<p>ファーストレイヤーキャリブレーションは、ノズルの先端とプリント面の距離を調整するためのものです。 押し出されたフィラメントが、わずかに押しつぶされてヒートベッドにぴったりとくっついている状態になるようにノズルの高さを調整していきます。</p>
<p>組立て済みのPrusaプリンターはすでに微調整されています。このキャリブレーションは、キットバージョンを組み立てた場合、またはノズルを変更する場合のみ必要となります。 ファーストキャリブレーションはウィザードの一部です(XYZキャリブレーションの最後のステップ)。 後で <em>LCD menu - Calibration - First Layer Calibration</em> から再度、ファーストキャリブレーションをすることもできます。 このキャリブレーションを実行中、プリンターがジグザグパターンをプリントしているときに、ノブを回してノズルとベッド間の距離を手動で調整していきます。</p>
<div class="warning-callout"> シートの種類（スムース、サテン、テクスチャー）ごとに厚みが異なるため、それぞれに異なるファーストレイヤーのキャリブレーションを使用する必要があります。そのために、便利な機能が用意されています。<a href="http://help.prusa3d.com/ja/article/steel-sheet-profiles_1955">スチールシートプロファイル</a>.</div>
<p>新しく組み立てたプリンタでは、値をゼロから開始して負( - )の値の方に移行させ、ノズルとヒートベッド間の距離を縮めていきます。初期のゼロ値は、P.I.N.D.A/SuperPINDA.の位置で設定されます。 <strong>ノブを反時計回りに回すと、ノズルがベッドに近づいていき、値がゼロから離れていきます。 &nbsp;</strong>この値はプリンタ毎に固有で、時間や使用歴によってわずかに変化する場合もあります。したがって <strong>高さを調節するときは、設定値ではなく、目視で確認する必要があります。 &nbsp;</strong></p>

<p>ファーストキャリブレーションが正しく設定されていないと、さまざまな問題が発生する可能性があります。 ノズルがプリント面から離れすぎると、プリントが適切に貼り付かないリスクがあり、<a href="http://help.prusa3d.com/ja/article/extruder-blob_2005">ブロブ</a> が発生する可能性があります。 一方、設定が近すぎると、 <a href="http://help.prusa3d.com/ja/article/clogged-nozzle-hotend-mk3-5-mk3s-mk2-5s_2008">詰まり</a> やプリント品質が低下するだけでなく、場合によってはヒートブレイクやプリントシートなど、ハードウェアが損傷する可能性もあります。<strong>プリントがくっつき過ぎることもあります。<a href="http://help.prusa3d.com/ja/article/flexible-steel-sheets-guidepost_2195">Flexible steel sheet</a></strong>したがって <strong>この作業を適切に行うことが重要になります。 </strong></p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01.jpg" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01-300x62.jpg 300w, http://help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01-600x125.jpg 600w" width="600" height="125" data-hd-align="center"></p>
<p>この作業を行う前に、プリント面 (サテン、スムース、テクスチャーのあるスチールシート) がきれいなことを確認してください。クニーニング方法については、 <a href="http://help.prusa3d.com/ja/article/first-layer-issues_1804">PEIプリント面の準備</a> を参照してください。 テクスチャー加工されたスチールシートとスムーズスチールシートを使ったときの外観には、いくらかの小さな違いがあります。よって、まずスムーズスチールシートで説明した後に、両方の写真とガイドラインを示します。</p>

<h3>スムーズシート</h3>
<h4>高すぎる</h4>
<p><strong>ラインは平らになっているが、押しつぶしが足りない。</strong> テストラインの最後にプリントする塗りつぶし四角形パターンで<strong>ライン間に隙間が発生しています。 (<span style="color: #e03e2d;">左の写真</span>)のようなときは、ノズルの位置が高すぎることを意味します。&nbsp;</strong>このときの値は、適正値よりもゼロに近い値になっています。</p>
<h4>低すぎる</h4>
<p>ノズルの位置が低すぎると (<span style="color: #e03e2d;">右の写真</span>) ラインが完全に押しつぶされており、最後の塗りつぶし四角形の<strong>ライン間に隆起が見られるときは、ノズル位置が低すぎるサインで</strong> 適正値よりゼロから離れた値になっています。 低すぎると、塗りつぶし四角形の端がめくれ上がりはじめることもあります。極端な場合、フィラメントが非常に薄く広がり、プリントされたフィラメントが透けて見えるようになり、ホットエンドの詰まりの原因にもなります。</p>
<h4>適正</h4>
<p>適正に調整すると、ライン間に隙間や隆起がなく、平らな表面 (<span style="color: #2dc26b;">中央の写真</span>) が形成されます。 先に述べたように、数値はP.I.N.D.A./SuperPINDAセンサーが固定されている位置とノズル先端の高低差によって異なります。これは各マシンで固有であり、プリントしたときの状況を目視でチェックしなければ意味がありませんが、目安としての<strong>一般的な範囲は-0.400 〜 -1.500です。</strong></p>

<h3>テクスチャー加工シート</h3>
<p>テクスチャー加工シートは、PEIのスムーズシートよりも薄いため、ノズルを少し近づける必要がありますが、スムーズシートと同じ結果を求めています。繰り返しますが、<strong>設定が低すぎると(<span style="color: #e03e2d;">右の写真</span>) 、フィラメントが付着していないように、フィラメントがエッジの周りで丸まり始める</strong>ことがあります。数値が適正値よりもゼロから遠すぎていますので、調整し直す必要があります。</p>
<p>ノズルの位置が高すぎると、ラインが丸くなり、最後の塗りつぶし四角形のライン間にギャップができます。この場合、値は適正値よりもゼロに近すぎています。</p>

<h3>ノズルを見ましょう</h3>
<p>1層目は約0.2mm/0.00787402インチです。 ノズルとシートまでの距離を目視で確認することも値の設定の役に立ちます。 ただし、プリントされた層をノギスで測定することは、最初の層の調整に推奨される方法ではありません。</p>

<h3>1層目のキャリブレーションを実行するタイミング</h3>
<p>一般に、&nbsp;<strong>1層目のキャリブレーション</strong> は、<strong>アセンブリに大きな変更</strong>があるたびに実行する必要があります。これには、ノズルの変更、エクストルーダーのアップグレード、またはその他の軸の更新などが含まれます。プリンタを別の場所に移動する場合も、すべてのキャリブレーションを実行する必要があります。</p>

<h3>概要</h3>
<div><strong>PETG</strong> は最も簡単にプリントできる材料の一つで、<strong>安価で初心者に適しています</strong>。 <strong>比較的高い靱性と耐熱性があるのでエンジニアリングパーツ</strong> (たとえばプリンターパーツ)のプリントに適しています。</div>
<div>&nbsp;</div>
<div><strong>推奨ノズル温度:</strong> 1層目が230℃ 、2層目からは240℃</div>
<div>&nbsp;</div>
<div><strong>推奨ベッド温度:</strong> 1層目が85℃、2層目からは90℃</div>
<div>&nbsp;</div>
<div><strong>シート:</strong> パウダーコートされたテクスチャーもしくはサテンシートの使用を強くお勧めします。スムーズPEIシートにプリントすると密着が高すぎてシートが破損することがあります。</div>
<h3>詳細な説明</h3>
<div>
<p><a href="https://shop.prusa3d.com/en/prusament/801-prusament-petg-prusa-orange-1kg.html"><strong data-stringify-type="bold">PETG</strong></a> (グリコール変性ポリエチレンテレフタレート) は一般的に使われる工業用プラスチックであり、<strong>低価格と優れたプリント性</strong>で3Dプリンターユーザーに人気があります。 粘り強く、優れた耐熱性を備えています; PETGは、層間の接着が優れているので、さまざまな機械部品、ホルダー、クランプ、および防水部品のプリントに最も一般的に使用されています。</p>
<p>PETGは表面に光沢があり、プリントシートに強く接着し、<strong>収縮や反りが少ないため</strong>（熱膨張がほとんどない）、大型モデルのプリントに適しています。 さらに、それの持つ高い粘り強さと柔軟性により、<strong>割れにくい材料といえます</strong>。 また、耐熱性も優れており、PETG部品は屋内および多くの屋外での使用（80℃未満の温度）に適しています。 <strong>私たちのプリンターの樹脂パーツはPETGで作られています！</strong></p>
<p>PETGの最後のGは、製造プロセス中にグリコールで変性されていることを意味します。 グリコールを使用すると、PETの脆性が下がり、プリントが容易になり、半透明のプリントで透明性が高まります。 もちろん、グリコールを含まないPETフィラメントでもプリントできます。 しかし、PETのプリントは難しいだけで、何のメリットもありません。</p>
<div class="warning-callout">PETG自体は<a href="http://help.prusa3d.com/ja/article/food-safe-fdm-printing_112313">食品安全</a>とみなされる場合がありますが、他のすべての3Dプリントと同様に、時間の経過とともにバクテリアが成長する可能性のある微小な隙間が存在する積層構造です。 <strong>食品安全な（エポキシ）コーティング</strong>を施すことでこれを防ぐことができます。 また、食品を扱うことが意図された用途である場合は、ステンレスノズルでプリントする必要があります。</div>
<p><strong>PETG</strong>は<strong>食品業界</strong>で多く使われており、<strong>食品安全</strong>とみなされていますが、食器や食品と直接接触するその他のものをプリントする場合は、PETG（またはその他のフィラメント）はお勧めしません。 主な理由は、細菌の成長を助長する多数の微細な積層間の表面溝が存在するためです。 ただし、それでも3Dプリントされた皿が必要な場合は、<strong>表面をシールする特別な層を適用し</strong>（食品安全コーティング）、きれいなステンレスノズルでプリントすることをお勧めします。</p>
<p>一部のメーカーは、<strong>PETGをさまざまな添加剤で強化</strong>し、別の名前で販売しています。 たとえば、E3DによるSpoolworks EDGEは、添加剤を使用して変更されたPET/共重合ポリエステルのブレンド品です。 目標は、より良いビジュアル品質、積層間の密着強度など上げることです。</p>

<h3>ベストな用途</h3>
<p>PETGは広く使用されていますが、屋内と屋外の両方で使用される機械部品に特に適しています。 私たちのプリンターの樹脂パーツのプリントにはPETGを使用しています！ ペットボトルも似たような素材で作られています。</p>
<h3>うまくプリントするためのヒント</h3>
<p><strong>温度設定と冷却</strong></p>
<p>PLAとは異なり、<strong>PETGには加熱ベッド（85℃）が必要です</strong>。 PETGのブリッジとオーバーハングの仕上がりは一般的に悪く、さらに糸引きが現象が出やすいです。 糸引きは、より早いリトラクションとより低いノズル温度で抑えられますが、<strong>うまく動作するようにチューニングされたPrusaSlicerプロファイル</strong>の使用をお勧めします。 <strong>PETGプリントでは冷却方法が重要なポイントです</strong>。冷却により、精細なモデルが可能になり、糸引きや垂れを防ぐことができます。 ただし、モデルの強度が気になる場合は、逆にプリントファンをオフにしてみてください。 フィラメント温度が高いほど、層間の結合が改善され、機械的性質が向上します。 それ以外の場合は、変形を防ぐためにプリントファンをオフにして最初の数層をプリントし、次にプリントファンを半分の速度で動かすことをお勧めします。 </p>
<div class="warning-callout">粘着力が強すぎて壊れる可能性があるため、<strong>スムーズPEIシートにプリントしないでください！</strong></div>
<p><strong>プリント表面の準備</strong></p>
<p><a href="http://help.prusa3d.com/ja/article/pei-print-surface-preparation_2203">別の記事</a>で説明されているように、プリントする面がきれいであることを確認してください。 <strong>パウダーコートされたプリントシートの1つを使用することをお勧めします。 粘着力が強くなりすぎることがあるため、スムーズPEIシートにプリントしないでください。</strong> どうしてもスムーズPEIシートを使用する場合は、プリントする前にプリント面にスティックのりを塗ってください。</p>
<p><strong>ソリッドパーツには、外周の数を増やしてください</strong></p>
<p>真にソリッドなパーツをプリントする場合は、インフィルを追加するのではなく、<strong>外周の数を増やして</strong>みてください。</p>
<h3>ポストプロセス</h3>
<p>PETGは、乾式と湿式の両方で簡単に研磨できます。</p>
<p><strong>PETGの溶解</strong></p>
<p><strong>PETGの溶解と平滑化</strong>は、熟練者が <strong>危険な化学物質</strong>（ジクロロメタン）を使用可能なラボ施設で作業することが必要になります。</p>

Manual changelog MMU2S

<p>When used with the new <strong>Multi Material Upgrade 2S</strong>, the new IR filament sensor needs to be calibrated before first use, in order to work properly. The calibration of the IR sensor is based on the position of the chimney (IR sensor holder) on the extruder. This calibration is purely mechanical. There is a warning in the assembly manual and the exact procedure is also described in the MMU2S Handbook you have received printed in the MMU package.</p>
<div class="warning-callout">If you do not have the <strong>Multi Material Upgrade 2S,</strong> this guide is <strong>not</strong> for you. You may be looking for <a href="http://help.prusa3d.com/ja/article/ir-filament-sensor-troubleshooting-mk2-5s-mk3s_112226">IRフィラメントセンサーのトラブルシューティング(MK2.5S, MK3S)</a>.</div>
<h4><strong>What does it look like</strong></h4>
<p>Even when there is no filament inserted in the MMU2S extruder, it is possible the sensor assumes the opposite. In a similar way, even during a print when the filament is in the extruder, it is possible the sensor suddenly stops registering it. It might then trigger filament change, or the 'Spool join' feature if you have it enabled.</p>
<div class="tip-callout">Since the 3.7.2 firmware version, the printer is able to test the functionality of the IR sensor by itself during the Selftest.</div>
<h4><strong>How to fix it</strong></h4>
<p>First of all, make sure your printer is running on <strong>firmware</strong> version 3.6.0 or higher. You should be always running on the latest <a href="http://help.prusa3d.com/ja/article/how-to-update-firmware-mk3s-mk3s-mk3_2227">firmware version for your printer model</a>.</p>
<p>We need to <strong>calibrate the position</strong> of the chimney that houses the filament sensor. The MMU2S modification of the MK3S extruder consists of 3 plastic parts: the FS-cover-mmu2s, the IR-sensor-holder-mmu2s, and the IR-sensor-cover-mmu2s. During the following procedure, <strong>move only with the IR-sensor-holder-mmu2s</strong>, for simplicity, we will continue calling this specific part "the chimney".</p>

<ol>
<li>Unscrew the Festo fitting of the PTFE tube leading from the MMU to the extruder.</li>
</ol>
<p><img decoding="async" style="max-height: 300px; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/odpojenej-lauch.png" data-hd-height="300px" data-hd-align="center"></p>
<ol start="2">
<li>Open the <em>LCD menu -&gt; Support -&gt; Sensor info</em> and focus on the <strong><em>IR value</em></strong> <em>(Fil. Sensor)</em>. <em>In firmware version 3.10.0 and newer this value is referred to as <strong>Fil. Sensor.</strong></em></li>
</ol>
<div class="note-callout">The IR sensor (Fil. Sensor) value has to be a stable 0 when there is no filament and a stable 1 as long as the filament is present in the extruder.</div>
<ol start="3">
<li>Loosen both M3 screws on the chimney. Move the chimney as far left as possible until the IR value (Fil. Sensor) is 0.</li>
<li>Tighten the M3 screws on the chimney.</li>
<li>Insert the smallest 1.5 mm Allen key (ideally the long one included in the MMU kit) instead of a filament into the extruder (without preheating), <strong>push it in between the Bondtech gears to move the lever</strong> (don't be afraid to apply a fair amount of downward force in order to get the key in between the gears). If the IR sensor (Fil. Sensor) value turns to 1, the calibration is done correctly.</li>
<li>If the IR sensor (Fil. Sensor) value stays at 0, pull out the Allen key from the extruder. Loosen the M3 screws on the chimney and move the chimney a tiny little bit to the right. Return back to step 4.</li>
</ol>
<div class="tip-callout">Check the chimney for little strings left after printing. These need to be cleaned out before attaching the IR sensor as it needs to have a clear field of view.</div>
<h4><strong>What if it does not work</strong></h4>
<div class="note-callout">Keep in mind that the idler screw tension is important too (idler screw is the one with the spring on it). The head of this screw should be flush with the extruder body, or slightly protruding from the left side.</div>
<ul>
<li>If the value is stuck on either 0 or 1 and it <strong>does not change</strong>, you may have overtightened the M3x40 screw that serves as the axle of the idler door. Try to loosen it a little bit.</li>
</ul>
<p><img decoding="async" style="max-height: 390px; margin-left: auto; margin-right: auto; display: block;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/anxle-screw.png" data-hd-height="390px" data-hd-align="center"></p>
<div class="warning-callout">The same applies to the <strong>M3x40 pressure screw</strong> with the spring on it - the head of this screw should be <strong>flush with the Extruder body.</strong></div>
<ul>
<li>Another screw that must not be overtightened is the <strong>M2x8 screw going through the IR sensor.</strong> Try to loosen it a little bit if it's screwed in tight, or, alternatively, tighten it if the sensor board is loose.</li>
<li>Also, check if your IR sensor PCB is not loose. If it is, it can slightly rotate around the screw which can influence the readings. The IR sensor board must be <strong>perpendicular to the lever.</strong></li>
<li>In case the <strong>sensor keeps showing 1</strong> even though the chimney is pushed all the way to the left, you first should make sure the filament was unloaded and changed correctly. <a href="http://help.prusa3d.com/ja/article/checking-re-aligning-the-bondtech-gear-mk3s-mk2-5s_133176">Make sure the Bondtech gear is aligned</a>.</li>
<li>It might be necessary <strong>to cut a small dent (roughly 0.5 mm)</strong> at the top of the lever with an Exacto knife. <strong>Do not remove more than 2 or 3 filament layers!</strong> It is very easy to clean up too much for the sensor to be functional, in which case you must print a new idler. Consider having a spare before doing so, or you must disconnect both the power and signal cable of the MMU2S to use the printer in single filament mode.</li>
</ul>

IR filament sensor calibration (MMU2S)

<p>If the selector of your MMU2S upgrade is not moving smoothly, or if it cannot reach a certain position, the cause is usually one of the following issues:</p>
<h3><strong>The selector blade is loose</strong></h3>
<p>The blade that is supposed to cut the filament strings was not attached properly or tightened enough during the assembly. It may have moved out of its socket and now it is blocking the movement of the selector.</p>
<ol>
<li>Release the three screws holding the selector motor in place (left picture) and pull the motor out by turning the threaded rod of the black trapezoid nut. <em>You can also release the two M3x10 screws securing the trapezoid nut.</em></li>
<li>Pull both of the small smooth rods out using the Allen key (right picture). Then remove the selector (<span style="color: #2dc26b;">green circle</span>).</li>

<h3>Updated selector blade holder</h3>
<p>The blade equipped with the selector, which will cut the tip of the filament unloaded from the extruder, if needed. Until firmware version 3.9.0 of the MK3S/MK2.5S the cutting function was not enabled.</p>
<p>To start using this function, make sure you have:</p>
<ul>
<li>Firmware 1.0.6 or above installed in the MMU2S unit.</li>
<li>Firmware 3.9.0 or above installed in the MK3S/MK2.5S.</li>
</ul>
<p>The printed parts for the selector (mmu2-blade-holder and mmu2-selector-finda) were updated to provide a better grip of the blade and are <a href="https://cdn.help.prusa3d.com/wp-content/uploads/Updated-MMU2S-blade-holder-and-selector.zip">available for download here</a>. <em>Print using PETG and PrusaSlicers 0.2 mm QUALITY preset.</em></p>
<h3><strong>The filament is bent and stuck in the selector</strong></h3>
<ol>
<li>Release the three screws holding the selector motor in place and pull the motor out by turning the threaded rod of the black trapezoid nut. <em>You can also release the two M3x10 screws securing the trapezoid nut.</em></li>
</ol>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/bfGEUfLI6f5Jwh3y.jpg" alt="" width="400" height="300"></p>
<ol start="2">
<li>Pull both smooth rods out (use the Allen key) and remove the selector.</li>
<li>Remove the broken filament string from the selector and reassemble the unit.</li>
</ol>
<h3><strong>The selector motor isn’t working</strong></h3>
<ol>
<li>First, try powering the printer off and moving the selector by hand, by turning the threaded rod.</li>
<li>If that didn’t help or if you were unable to move the selector, release the three screws holding the selector motor in place (picture above) and pull the motor out.</li>
<li>Push the smooth rods out with an Allen key. You can now easily remove the selector.</li>
<li>Clean any stuck filament and try pressing the left and right control buttons. See if the motor’s shaft rotates. If not, the motor may be defective, or it is plugged incorrectly. Remove the MMU board with its cover and <strong>cross-check with the picture on the right</strong> to see if that is the case. Try also to unplug the cables and plug them back in to be sure.</li>

MMU2S Selector not moving

<p>リモートでファイルを転送し、プリントをスタートする方法があるように、SDカードやUSBフラッシュメモリは、最も一般的で信頼性の高い方法です。一般的で便利ではありますが、フラッシュメモリーはそれ自体最も信頼できるものではなく、ストレージが破損したり、明らかな兆候なしに容量がいっぱいになってしまうことがあります。そこで、Original Prusaプリンタ用のメモリーのメンテナンス、フォーマット、購入の方法について、ガイドをまとめました。</p>
<h3>SDカードがロックされていないか確認しましょう</h3>
<p>SDカードの側面には、ラッチが付いています。SDカードを使用する前に、ラッチが「ロック」の位置になっていないことを確認してください。ロックされている場合、カードにファイルを保存することができず、プリンタもSDカードを開くことができません。</p>
<p><img decoding="async" style="max-height: 350px; display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01.jpg" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01-300x293.jpg 300w, http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01-410x400.jpg 410w" data-hd-height="350px" data-hd-align="center" /></p>
<h3>32GBを超える容量の場合</h3>
<p>対応する記憶媒体の容量に上限はありませんが、<strong>Windows内蔵のフォーマットツールは、32GB以上の記憶媒体をFAT32にフォーマットすることはサポートしていません。</strong>弊社プリンタでは現在サポートしていないexFATのオプションが提供されるのみです。Apple社のOSxの各バージョンでも同様の制限があり、正しくフォーマットするためにはサードパーティーのアプリケーションを使用する必要があります。</p>
<p>このようなドライブをフォーマットするには、Rufus、FAT32フォーマット、またはEaseUS Partition Masterなどのサードパーティアプリケーションが必要です。このようなプログラムを使用するときは、誤ってハードディスクなどの間違った記憶媒体をフォーマットしないように注意してください。ただ、Gコードファイルが100MBを超えることはほとんどないため、容量が8～16GBあればほとんどの場合は十分です。</p>
<h3>USBドライブ/SDカードをフォーマットする方法</h3>
<p>SDカードやUSBドライブの容量がいっぱいになってしまった場合や、ドライブの中身は読めないものの、ドライブ自体はWindowsで認識される場合、ほとんどの場合、ドライブをフォーマットすると解決します。</p>
<div class="note-callout">USBドライブやSDカードがコンピュータのエクスプローラにも表示されない場合は、修復不可能なほど破損しているか、少なくともこの記事でフォローできる範囲を超えている可能性があります。下の写真のようなエラーが発生し、どこにも表示されない場合は、googleで検索してください。</div>

<h3>Windowsでのフォーマット方法</h3>
<p>Windowsの場合は非常に簡単です。マイコンピュータでUSBドライブまたはSDカードを探し、右クリックして、フォーマットを選択します。</p>
<p><img decoding="async" style="max-height: 350px; display: block; margin-left: auto; margin-right: auto;" src="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03.png" sizes="100vw" srcset="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-300x288.png 300w, http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-417x400.png 417w, http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-768x737.png 768w, http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-625x600.png 625w" data-hd-height="350px" data-hd-align="center" /></p>
<p>新しく小さなウィンドウがポップアップ表示されます。ほとんどの場合、すべてをデフォルトのままにしておけばよいのですが、<strong>最も重要なのは、File SystemがFAT32に設定されていることです。</strong>この設定とボリュームラベル（ドライブの名前）を設定してください。Startをクリックすると、数秒でドライブがフォーマットされます。</p>
<div class="warning-callout">ドライブをフォーマットすると、そのドライブの内容がすべて消去されてしまいます。バックアップを取るようにしてください。</div>
<p><img decoding="async" style="max-height: 300px; display: block; margin-left: auto; margin-right: auto;" title="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-166x300.png 166w, http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-222x400.png 222w" src="http://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04.png" data-hd-height="300px" data-hd-align="center" /></p>
<div class="note-callout">この手順を行ってもUSBメモリが動作しない場合は、USBメモリが壊れているか、「パーティションスキーム」がGPTに設定されているため、正しくありません。MBR(Master Boot Record)に設定する必要があります。変更方法については、マイクロソフト社の公式ドキュメントをご参照ください。<a href="https://docs.microsoft.com/en-us/windows-server/storage/disk-management/change-a-gpt-disk-into-an-mbr-disk">Microsoft's official documentation</a>.</div>
<h3>Macでフォーマットする方法</h3>

ファームウェアのアップデート時の問題 (MK2S/MK3S/MMU2S)

<p>As you can see, there are five main LEDs on the MMU2 unit. Their arrangement corresponds to the arrangement of the 5 PTFE tubes and 5 filament channels. Each LED consists of two sub LEDs: <span style="color: #e03e2d;" data-hd-color="#fb9e00"><strong>Red</strong></span> status LED <span style="color: #68bc00;" data-hd-color="#68bc00"><strong>Green</strong></span> status LED.</p>
<h3><strong>Green light</strong></h3>
<p>As you would guess, the green light means that everything works as it should.</p>
<ul>
<li><strong>Stable green light (not flashing)</strong> - selector moved to the current position and ready.</li>
<li><strong>Stable green light after loading</strong> - filament successfully loaded.</li>
<li><strong>Rapid green flashing light (after pressing the middle button)</strong> - The filament loading sequence.</li>
</ul>
<p>This sequence won't stop until FINDA senses the filament flowing through or the user cancels the operation pressing the middle button.</p>
<p><img decoding="async" style="max-height: 20em; max-width: 20em; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/m-zvmz-54-h-e-1-qqaw.jpg" data-hd-height="20em" data-hd-width="20em"></p>
<h3><strong>Red light</strong></h3>
<p>As for the red light, its meaning also depends on the context:</p>
<h4><strong>Stable red light (not flashing)</strong>&nbsp;</h4>
<p>Wait until the printer finishes the current activity (there is not necessarily a problem).</p>
<p><img decoding="async" style="max-height: 20em; max-width: 20em; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/gc-3-m-ljxnfn-vmjwue.jpg" data-hd-height="20em" data-hd-width="20em"></p>
<h4><strong>Slow flashing during print</strong>&nbsp;</h4>
<p>An error occurred during the filament <strong>load.</strong></p>
<ol>
<li>Pull the problematic filament out from the PTFE tube and cut the end to create a sharp tip</li>
<li>Insert the filament back into the white PTFE tube</li>
<li>Press the middle button to start the loading sequence</li>
<li>Push the filament until it’s caught by the drive gear</li>
<li>If the LED turns red and green, press the right button for 1-2 seconds to continue the print</li>
<li>If the LED turns red, repeat the process.</li>
</ol>
<h4><strong>Rapid flashing during print&nbsp;</strong></h4>
<p>An error occurred during filament <strong>unload.</strong></p>
<ol>
<li>Remove the orange/white PTFE tube by unscrewing the silver fittings from MMU2 body</li>
<li>Check whether there’s a filament string stuck in the MMU2’s selector</li>
<li>Pull the filament out from the orange/white PTFE tube:
<ul>
<li>If you’re unable to remove the filament from the tube, proceed to the other end of the tube</li>
<li>Release the Festo fitting on the extruder and if needed open the extruder idler</li>
<li>Then pull the filament out from the extruder body</li>
</ul>
</li>
<li>Using your fingers move the filament back in the MMU unit and leave about 1 cm sticking out.</li>
<li>If the filament is stuck inside the selector and you’re unable to move it, press the left button - this will start load/unload:
<ul>
<li>If the printer failed at the loading stage the button works in loading mode</li>
<li>If the printer failed at the unloading stage, the button is in unloading mode</li>
<li>The middle button will be used now. Press it once and wait for the printer to finish the auto-check procedure.</li>
</ul>
</li>
<li>If the procedure finishes correctly, the LED above the affected filament will turn to red-green flashing, if the procedure fails it will remain red.</li>
<li>To continue after fixing the issue, press the right button.</li>
</ol>
<p style="text-align: center;"><iframe loading="lazy" src="https://www.youtube.com/embed/nx_ICcW3trM" width="640" height="360" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p>
<h4><strong>All five LEDs blinking red after power on</strong></h4>
<p>If the filament is present in the selector during power-up, it’s detected by the FINDA and the standard booting move sequence is interrupted, as it would bend or break the filament. Remove the filament manually first so the boot can continue. No need to press any button. As soon as you take the filament out, the printer will continue by itself.</p>
<ol>
<li>Try to pull the problematic filament out from the back.</li>
<li>If you’re unable to pull the filament out, try powering the printer off and try again.</li>
<li>You can unscrew the FESTO coupling from the MMU2 selector and instead pull the filament out from this side. If you’re able to pull the filament out in this direction, cut it near the spot where the filament enters the white PTFE tube.</li>
<li>As a last resort, remove the selector motor by unscrewing the 3 screws holding it and push the smooth rods out with an Allen key. You can then easily remove any debris stuck in the selector.</li>
</ol>
<h4><strong>All five red and green LEDs blinking</strong></h4>
<p>Resetting the MMU2S using the reset button on the side of the unit is usually enough. However, if all the LEDs keep on flashing simultaneously, then it may be a power issue:</p>
<ul>
<li>Inspect the signal cable and MMU2S power cable for damages and check if they are properly connected to the MMU2S control board and to the printer's Einsy board.</li>
<li>Verify the proper connection of the <a href="http://help.prusa3d.com/ja/article/ir-filament-sensor-troubleshooting-mk2-5s-mk3s_112226">filament sensor to the Einsy board.</a></li>
<li>Try flashing the firmware of the MMU2S unit again, even if you are on the most current version.</li>
</ul>
<p>&nbsp;</p>

<p></p>


MMU2S LEDs meaning

<p>As the MMU unit has its own separate logic board, it also has its separate firmware that is cooperating with the printer firmware. This MMU-specific firmware is flashed directly to the MMU2S unit, using the micro USB port.</p>
<div class="tip-callout">The firmware for the MMU2S unit is <a href="https://www.prusa3d.com/drivers/">available here</a>. The .zip package contains one MK3S+MMU2S firmware file, all possible MK2.5S+MMU2S firmware files, and <strong>one MMU firmware file</strong>.</div>
<p>On the right side of the MMU unit, there is a reset button. You can push it with an Allen key or with a similar thin, hard object. This button serves as a soft reset: it makes the MMU go through the initialization sequence and makes the selector return to the default position. This button <strong>does not</strong> serve for factory reset.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button-600x386.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button-800x515.png 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button-300x193.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button-768x494.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/02/mmu2_reset_button-1536x988.png 1536w" alt="mmu ports" width="600" height="386" loading="lazy" /></p>
<h3>Factory resetting the MMU2S firmware</h3>
<p>Note that the factory reset is a <strong>hard reset</strong> of the MMU firmware: it will delete the filament length calibration values. The MMU2S will calibrate the filament length automatically and store this value. The firmware version will not be changed.</p>
<div class="warning-callout">The procedure of entering the service menu and of factory resetting has changed a few times. <strong>The process described below works for MMU firmware version 1.0.5. and higher.</strong> It is not necessary anymore to observe or wait for the initialization sequence.</div>
<div class="tip-callout">You can find out your firmware version number by navigating to <em><strong>LCD menu -&gt; Support</strong></em> and scrolling down until you see <strong>MMU2 connected, FW:</strong> [firmware number<strong>]</strong></div>
<ol>
<li>The printer and the MMU must be on. <strong>Press and release the printer reset button</strong> (marked X and positioned under the control knob on the LCD panel).</li>
<li><strong>Immediately</strong> after releasing the X button, press the middle black button on the MMU unit and hold it.</li>
<li>Release the button <strong>only</strong> when in the first LED position, both the green and the red LEDs are on, and at the same time, in the fifth LED position, the red LED is on. See the photo below.</li>

Factory reset (MMU2S pre firmware 1.0.6)

フィラメント詰まり（MMU2S）

<p>The FINDA sensor, sometimes referred to as F.I.N.D.A. is essentially the MK2/S PINDA sensor (without thermistor), upcycled to be used as a filament sensor. It is triggered by the proximity of the stainless steel ball. When the filament is pushed through the selector, it raises the ball towards the FINDA. There is a small red LED light on the top of the sensor that <strong>turns OFF when the filament is detected</strong>. When the filament is removed, the stainless steel ball falls back down and the red light turns ON.</p>
<div class="warning-callout">The FINDA is <strong>not</strong> the same as the P.I.N.D.A. or SuperPINDA used on the MK2.5S and MK3/S/+ extruder. These are not interchangeable with the FINDA and it is important to differentiate the different Original Prusa induction sensors.</div>
<p style="text-align: center;"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted.jpeg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted-600x391.jpeg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted-800x521.jpeg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted-300x195.jpeg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted-768x500.jpeg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/03/658bd1dcd75f59c1_painted-1536x1000.jpeg 1536w" alt="" width="600" height="391" loading="lazy" /></p>
<p style="text-align: center;"><em>The FINDA sensor must be distanced correctly from the steel ball (<span style="color: #236fa1;">blue ruler</span> - left picture) so it is triggered <strong>only</strong> when filament is present (<span style="color: #2dc26b;">green arrow</span> - right picture), pushing the steel ball higher.</em></p>
<h3>FINDA height setup</h3>
<p>The FINDA sensor has to be properly inserted into its socket: <strong>not too low, not too high</strong>. Check out our assembly manual, specifically <a href="http://help.prusa3d.com/ja/guide/8-preflight-check-calibration_219068#219937">this step</a>, to see how the FINDA fits in.</p>
<ol>
<li>Supposing the steel ball and the FINDA are still in the selector, loosen the M3x10 screw holding the FINDA in place. Do not remove the screw, you just need to be able to move the FINDA up and down.</li>
<li>Open the <em>LCD menu -&gt; Support -&gt; Sensor info</em> and focus on the <strong>FINDA value.</strong></li>
<li>Insert any 1.75 mm filament into the selector. The FINDA value <strong>should turn from 0 to 1</strong>.
<ul style="list-style-type: disc;">
<li>If it does not change from 0 to 1, <strong>push the FINDA down</strong> a little bit. Keep in mind you must be able to move with the filament freely!</li>
<li>If it does change reliably from 0 to 1 as long as the filament is inserted, the calibration is done.</li>
</ul>
</li>
</ol>
<div class="note-callout">The tip of the sensor does <strong>not need to press directly on the steel ball</strong> in order to detect it, it is triggered by the magnetic field. Thus, do not press the FINDA down during step 3.</div>
<p>Finally, tighten the M3x10 screw to prevent the FINDA from moving. The steel ball, however, has to move freely!</p>
<h3>FINDA troubleshooting</h3>
<h4>Debris in the selector</h4>
<p>As explained in the first paragraph, the steel ball has to move freely. Sometimes, however, filament <strong>debris, dust, or strings</strong> may amass in the hole or even in the FINDA/ball socket. <strong>Use compressed air to clean it</strong>.</p>
<div class="tip-callout">You can also use an interdental brush to clean debris. The diameter should be around 1.5 mm (0.06”) and the length should be 10-15 mm (0.4-0.6”)</div>
<h4>Faulty sensor</h4>
<p>You can always check the proper functioning of the sensor by inserting a piece of filament and <strong>observing the red light</strong> on top of the sensor. You can also go to the <strong><em>LCD Menu -&gt; Support -&gt; Sensor info</em></strong> to see the FINDA status. It should be 0 when the filament is out (red LED on) and 1 when the filament is inserted into the selector (red LED off).</p>
<p>In some situations, the FINDA itself may be working but its <strong>cable might be damaged</strong> and fail to transfer the information to the logic board. In most cases, it can be damaged during the assembly while doing cable management. It can be also damaged by opening the Idler body all the way and having it hang on the cables.</p>
<p>The best way to check the cable is to insert a piece of filament into the selector and go to the Sensor info menu. The FINDA value should be 1. Then <strong>wiggle with the cable</strong> and see if the value flickers and changes to 0 at any point.</p>
<h4>Wiring</h4>
<p>In case the FINDA value in the Sensor info menu is <strong>N/A</strong> during manual testing, check <a href="http://help.prusa3d.com/ja/guide/6-electronics-and-mmu2s-unit-assembly_44728">the cable connection to the MMU logic board</a> and the MMU cable connection into the RAMBo board (<a href="http://help.prusa3d.com">MK3S</a> / <a href="http://help.prusa3d.com">MK2.5S</a>). Pay attention to the <strong>order of the colors</strong> of the individual wires. <strong>However, during load and unload, the FINDA value in the Sensor info menu will be N/A.</strong></p>
<p></p>

FINDA setup and troubleshooting

<p>If your Original Prusa Multi Material idler barrel has some issues moving, makes clicking noises, or gives the error <a href="http://help.prusa3d.com/ja/article/idler-cannot-home-04125-mmu_395865">#04125 Idler cannot home</a>, something is preventing the full movement of the idler barrel.</p>
<h3>Loosen idler cover</h3>
<p>First, check the idler screws' tightness. Too much tension can prevent the motor from turning the idler barrel. You can try completely loosening the tension screws, and allow the MMU to finish the homing. If it passes, then the idler cover is too tight.</p>
<p>To find the perfect tension, tighten the screw about 0.1 mm to 0.4 mm under the edge of the hole on both sides of the idler body. All 5 filaments have to be loaded to the hobbed pulleys position. Then move with the selector to the far right (5th filament position) and back and observe. If you hear clicking, loosen the screws a bit and try to move with the selector again until there is no more clicking.</p>

<h3>Check the idler barrel path</h3>
<p>If the idler does not rotate freely with the spring screws loosened, you can open the idler completely and verify that nothing's blocking it, like the remains of filament or dirt. Check if the idler is centered and if the edges of the idler don’t grind the idler body.</p>
<p>Check the idler barrel connection with the Idler motor. The plastic around the motor shaft cannot be broken or worn out, which can happen due to heat. Move the barrel across the whole axis by hand, and make sure that during the whole range of rotation, the barrel does not touch the cover and does not scratch against the sides.</p>
<p>If the barrel is bent in relation to the rest of the idler, try loosening the two screws that connect it to the Idler motor, and tighten them again gently. Make sure that the two screws are tightened evenly against the flat part of the motor shaft.</p>

<h3 class="hd--html">Change Stallguard threshold</h3>
<p>If you are getting the <a href="http://help.prusa3d.com/ja/article/idler-cannot-home-04125-mmu_395865">#04125 Idler cannot home</a> error, the printer will give you two options. You can either click to Retry or Tune. If the issue is persistent even though you checked all the items above, you can lower the Stallguard value.  If the threshold is too high the MMU will not home. Therefore, start from the default value of 7, and decrease the value by 1.</p>

MMU2S idler unable to move freely

サービスメニュー - 工場出荷時リセット

<h3>What happened?</h3>
<p>While loading to the extruder, as soon as the filament sensor detects a filament the printer performs an automatic loading check. If the check fails, this error is shown. Each failed load might be accompanied by the printer beeping.</p>
<p>The printer’s automatic loading check loads approximately 40mm of filament and then unloads 30mm of it. If the filament sensor stops detecting a filament at any time during the process, the error is shown. This process is very sensitive, so making a precise Filament sensor calibration is needed in order to prevent print defects.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/07/a0439f90aec30ca2278a45e6164a7c07_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Load to Extruder failed" alt="" width="450" height="338" loading="lazy" />  <br />While your MK3S+ is performing the loading check, <strong>solid blocks</strong> should be generated on the bottom of the LCD representing the IR filament sensor <strong>detecting a filament</strong> during the process.</p>
<p>If there is a<strong> line instead</strong> of any blocks (drop in the sensor’s reading), this means that the sensor <strong>stopped detecting</strong> filament at that moment, resulting in a failed loading check. The printer then retries the load. If the cut function is enabled, the MMU tries to cut a filament tip. If the drop while loading persists even during the retries, the printer unloads the filament and shows the error.</p>
<h3>How to fix it?</h3>
<ul>
<li>Redo the <a href="http://help.prusa3d.com/ja/article/ir-filament-sensor-calibration-mmu2s_2245">IR filament sensor calibration (MMU2S) [進行中の翻訳]</a>.</li>
<li>While the printer is Idle, you can use the Loading test in <em>LCD menu -&gt; Settings -&gt; Loading Test</em> to verify the filament is able to load properly.</li>
<li>Undo the PTFE tube from the FESTO fitting and pull the filament out by hand to inspect it. The last 40cm (15") of each should have no dents in it, or the gears won't be able to grab the filament. Cut off part of the filament with defects such as indentation or a deformed tip. Make sure the filament end is straight and has a sharp tip at the end. Reattach the PTFE tube and hit Retry.</li>

<li>Inspect the filament spool and the buffer for excessive friction or filament jam. Make sure the filament is able to move freely.</li>
<li>Use only high-quality filaments. Certain poor-quality filaments or very specific types of material might not work correctly with the MMU.</li>

Load to extruder failed #04108 (MMU)

<p>This article is describing the status of the LEDs located on the multi material unit. Together there are five LEDs on the unit that correspond to the five available filament positions. </p>
<div class="warning-callout"><strong>Attention</strong>: MMU3 issues should be primarily resolved using the error codes displayed on the printer's screen. This article explains basic LED statuses and also includes information for developers.</div>
<div class="note-callout">This article is valid for the MMU3 <strong>firmware 3.0.0 </strong>and up. <br />Note that the earlier MMU2S firmware 1.0.6 or below behaves differently.</div>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/07/cc78fe05f7942c4acdaf41c0620e402a_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Status LED explained (MMU3)" alt="" width="450" height="338" loading="lazy" /></p>
<h3>During the regular MMU operation: </h3>
<ul>
<li>GREEN solid light: The MMU has a record of the given filament being loaded in the extruder.</li>
<li>GREEN flashing light: There is a loading/unloading process going on.</li>
<li>RED flashing light: There is a loading/unloading error with the given filament. The unit is waiting for user interaction.</li>
<li>RED and GREEN flashing lights: Internal runtime error, refer to the error shown on the printer’s LCD.</li>
</ul>
<h3>MMU Firmware start:</h3>
<p>After the MMU unit has been turned on or restarted, green LEDs light up from positions 5 to 1 shortly (~100ms). Each signalizes one component up and running: </p>
<ul>
<li>LED 5: Shift registers initialization</li>
<li>LED 4: USART initialization</li>
<li>LED 3: SPI communication initialization</li>
<li>LED 2: motion system initialization</li>
<li>LED 1: ADC initialization</li>
</ul>
<p>If the MMU stops in this setup phase (the LEDs stay on and do not turn off), something is wrong with the electronics.</p>
<p>Then, a selftest routine is performed. It checks if the main control board behaves correctly and if all the signals from the microcontroller get to the TMC motor drivers on the control board properly. If the MMU unit suspects the communication with any of the three TMC motor drivers might not behave correctly, an error is shown. In that case, refer to the printer’s LCD screen.</p>
<p>LED lights indicate the ongoing phases of the selftest routine:</p>
<ul>
<li>LED 1: ok (green) / error (red) on STEP signal</li>
<li>LED 2: ok (green) / error (red) on DIR signal</li>
<li>LED 3: ok (green) / error (red) on ENABLE signal</li>
<li>LED 4 indicates which TMC driver is being tested
<ul>
<li>Idler = green</li>
<li>Selector = red</li>
<li>Pulley = green+red</li>
</ul>
</li>
<li>LED 5 is flashing green while the process is still ongoing.</li>
</ul>
<h3>Other LED lights on the unit: </h3>
<p>There are also other less important LED indicators on the unit.</p>
<ul>
<li>A green LED on the MMU3 PD-board addon, on the back of the unit. It signalizes the board receiving power from the printer.</li>
<li>An orange indicator "breathing" on the inside of the MMU unit, on the main control board, signalizes the electronics booting up.</li>
<li>A red indicator on the top of the FINDA sensor signalizes the sensor being powered up and NOT detecting a filament.</li>
</ul>
<p></p>

<h3>What happened?</h3>
<p>While the MMU unit was unloading a filament, the SuperFINDA sensor inside the selector stayed triggered/detecting a filament, while it shouldn’t. </p>
<div class="note-callout">The superFINDA might be referred to as FINDA on the printer.</div>
<h3>How to fix it?</h3>
<p>Check if the filament has been unloaded or not.</p>
<p>If the filament has been unloaded, but the superFINDA is still triggered, open the Festo fitting connected to the selector, and check if there is anything stuck in the selector (e.g. broken filament, string).</p>
<p>Also, make sure that the superFINDA is working: <a href="http://help.prusa3d.com/ja/article/finda-setup-and-troubleshooting_2250">FINDA setup and troubleshooting [進行中の翻訳]</a>.</p>

<p>In case the filament is stuck between the MMU unit and the extruder, remove the PTFE tube from the FESTO fitting. Remove any debris that might be stuck in the PTFE tube. pull out approx. 40cm of filament and inspect it for indents. If there are any, cut off the damaged part of the filament, re-install the PTFE tube, and hit Retry.</p>
<p>Make sure that the tip of the filament is sharp, and not stringy or expanded so that the issue does not happen again.<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/db89b73cc9e446ce_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="FINDA: Filam. Stuck #04102 (MMU)" alt="" width="400" height="300" loading="lazy" /></p>
<p>If there is any debris or broken pieces of filament inside the selector, it can be cleared up using the 1.5mm Allen key, if you remove the FESTO fitting and move the selector all the way to the right. If the SuperFINDA sensor was triggered due to debris / broken filament, the actual filament might be far behind the pulley wheel and might need pushing into the MMU from the back, while retrying the loading operation.</p>
<p>Multi-material operation is sensitive to proper temperature settings. Check that you are using the correct settings for the given material in Slicer. Incorrect nozzle temperatures will cause issues with filament load/unload. Note that with MMU, some 3rd party filaments might behave differently than during the single-material operation even with the same settings.</p>
<p>Some filaments sensitive to moisture might need to be dried out before use. Moist filaments are usually more stringy and this might cause the filaments to jam. You can read more about how to lower the stringing in our <a href="http://help.prusa3d.com/ja/article/stringing-and-oozing_1805">糸引きと垂れ</a> article.</p>
<p>It is recommended to use only high-quality filaments. Certain poor-quality filaments or very specific filament types won’t work correctly with the MMU. In this case, change the slicer settings according to the manufacturer's instructions.</p>

FINDA: Filament Stuck #04102 (MMU)

<p>Information from the data logged via serial line can be useful when doing advanced troubleshooting with your MMU2S unit or for providing it to <a href="http://help.prusa3d.com/ja/article/customer-support_2287">カスタマーサポート</a> when requested.</p>
<p>To obtain the log you will need to connect the printer to a Windows computer or to RPi/Linux computer.<br />When you connect the printer by the USB cable to a Windows computer, the printer should be showing up in the Windows Device Manager as a “COM device” under “Ports (COM &amp; LPT). Write down or remember the number of the COM port.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Windows-ports.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Windows-ports-300x52.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Windows-ports.jpg 1600w" alt="" width="300" height="53" loading="lazy" /></p>
<p>The port number can be also found in the PrusaSlicer menu under <em>Configuration -&gt; Flash Printer Firmware</em> and then in a row labeled Serial Port. This is applicable to Linux as well.</p>
<p>You will also need to download the logging script. It is available for Windows and for Linux.</p>
<h4>Windows</h4>
<p>To register the Multi-material log using Windows, find the script in <a href="https://gist.github.com/heiswayi/10b412aa96d3f35d85f5f8c2e0075a33#file-serialportreader-ps1">GitHub</a>, and do the following:</p>
<ol>
<li>Connect the printer with the USB cable to a Windows computer.</li>
<li>Paste the code from <a href="https://gist.github.com/heiswayi/10b412aa96d3f35d85f5f8c2e0075a33#file-serialportreader-ps1">GitHub</a> to Notepad++.</li>
<li>Go to <em>File -&gt; Save as</em> and save the file as Windows PowerShell (*.ps1;*.psm1).</li>
<li>Right-click the saved script file and from the menu select “Run with PowerShell”.</li>
<li>If you get asked about “Execution Policy Change”, press “Y” [Yes].</li>
<li>When prompted for “PortName”, enter the COM port your printer uses, e.g. "COM4" and hit Enter.</li>
<li>When prompted for “BaudRate”, enter “115200” and hit Enter.</li>
<li>After that, the script will start showing the communication between the printer and the MMU2S unit. It will also start saving everything into a .log file in the same folder where the script is located. (For example “2022-08-08-MMU.log”).</li>
<li>Try to reproduce the MMU2S errors you are looking to resolve and mark down the time they occurred.</li>
<li>To stop the script from running, press Ctrl+C or close the window.</li>
</ol>
<p>The above steps should show a log similar to the one below. This is an example of one failed attempt at the “Load to nozzle” function for filament #3 (with MMU2S firmware 1.0.6).</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Load-to-nozzle-mmu-fail.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Load-to-nozzle-mmu-fail-600x400.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Load-to-nozzle-mmu-fail-300x200.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/11/Load-to-nozzle-mmu-fail.jpg 1600w" alt="" width="500" height="334" loading="lazy" /></p>
<h4>Linux</h4>
<p>In order to run the Linux script, you will need to have installed some extra packages. You can install them using this command:</p>
<p><code class="codesample-inline">sudo apt install socat rlwrap tio moreutils</code></p>
<p>Linux script:</p>
<p><code class="codesample-inline">log=${1}<br />
dev=${2:-/dev/ttyACM0}<br />
dsc=${3}<br />
rate=115200<br />
prefix=${log%%_log.*}<br />
echo $3 &gt;${prefix}_dsc.txt<br />
​<br />
if [ -z "$log" ]; then<br />
  echo "Usage: $0 &lt;log&gt; [device] &lt;description&gt;"<br />
  exit 2<br />
fi<br />
echo "Log: $log"<br />
echo "Port: $dev"<br />
echo "Description: $dsc"<br />
echo "Dsc file: ${prefix}_dsc.txt"<br />
​<br />
{ rlwrap -a -S '&gt; ' tee &gt;(sed -ue 's/^/SEND /' &gt;&amp;2)<br />
  | socat - "$dev,b$rate,cfmakeraw" | sed -ue 's/^/RECV /'<br />
} 2&gt;&amp;1 | ts '[%Y-%m-%d %H:%M:%.S]' | tee "$log"<br />
 </code></p>
<p>To register the Multi-material log using Linux, do the following:</p>
<ol>
<li>Connect the printer with the USB cable to a Linux computer.</li>
<li>Create a .sh file using the script above (file name example: <strong>prn-session2.sh</strong>).</li>
<li>You will need to know the name of the serial port the printer is connected to in your system. For example, to log to a <strong>file test1_log.txt</strong>, using the serial communication on <strong>/dev/ttyACM0</strong> and a with a description <strong>"MMU2S logging 08-08-2022"</strong> run the following command: <strong>sudo ./prn-session2.sh "test1_log.txt" /dev/ttyACM0 "MMU2S logging 08-08-2022"</strong>.</li>
<li>After that, the script will start showing the communication between the printer and the MMU2S unit. It will also start saving everything into a .log file.</li>
<li>Try to reproduce the MMU2S errors you are looking to resolve and mark down the time the error occurred.</li>
</ol>
<p>The above steps should show a log similar to the one below. This is an example of a successful attempt at the “Load to nozzle” function for filament #1 (with MMU2S firmware 1.0.6).</p>

Logging data over serial line (MMU2S)

<h3>What happened?</h3>
<p>The Original Prusa MMU3, as well as the MMU2S with firmware version 3.0.0 or higher, feature a voltage sensing function managed by the Main Control Unit (MCU). This function monitors the 5V line supplying the logical components with power. It helps prevent malfunctions in the control board's components due to inadequate power supply. If the MCU senses insufficient power, the printer will display the message:<strong> "MMU MCU detected a 5V undervoltage. There might be an issue with the electronics. Check the wiring and connectors".</strong></p>
<p>Error name: MMU MCU Underpower</p>
<p>Error code: #04307</p>
<p><span style="font-size: 17.55px; font-weight: bold;">How to fix it?</span> </p>
<div class="warning-callout">Do not touch, move, connect, or disconnect any cables or electronic components while the printer is on. This can result in irreversible damage! </div>
<p>Access the MMU control board, and inspect it visually to spot any incorrect assembly, or damage on its surface or damage to the cables. Attempt reseating the cables to ensure their connection. In case of poor cable connection, clean the connectors mating surfaces. In particular, make sure that the MMU3 <strong>PD-board</strong> add-on is attached to the control board.</p>
