<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>

<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>

Load to extruder failed #04108 (MMU)

<h3>What happened?</h3>
<p>Implausible reading by the Filament sensor inside the extruder, while loading a filament. The filament shouldn't be in the extruder yet but is detected there anyway. </p>
<div>
<h3>How to fix it?</h3>
<p>Remake 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>. </p>
<p>Open the extruder idler and make sure that there is no leftover filament in the extruder causing the sensor to trigger too early.</p>

Filament sensor too early #04106 (MMU)

<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)

<h3>What happened?</h3>
<p>Before it can align with any of the filament positions, the Idler inside the MMU unit needs to be “homed” to determine its position. First, the Idler moves to one end of the travel (endstop). Then, it moves to the other endstop, while measuring the angle between the end stops. The idler homes after the unit starts up has been reset or after another error occurred.</p>
<p>In case it can’t find the first homing endstop or the distance between the two endstops differs from the expected value, the printer will show an error. </p>
<p>Distance between the Idler endstops: 225 degrees <br />Allowed deviation: 10 degrees</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/a145b287aabbda1b90de462656d26eec.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Idler cannot home #04125 (MMU3)" alt="" width="450" height="338" loading="lazy" /></p>
<div class="note-callout">Endstops are detected using the StallGuard function. Note that the Stallguard readings are ignored while the Idler moves over the filaments to mitigate false readings.</div>
<h3>How to fix it?</h3>
<p>The issue is usually mechanical. If you get this error, check the following items:</p>
<ul>
<li>Verify there is no debris around the Idler and that it can move freely.</li>
<li>Release the idler tension screws slightly. If it is too tight, it will disable the Idler from moving freely.</li>

MMU MCU Error #04306 (MMU)

<h3>What happened?</h3>
<p>Implausible SuperFINDA reading. This error happens when a filament is detected by the SuperFINDA sensor although the MMU doesn’t have a record of any filament being loaded. It is unsure of which position the filament is loaded in so it can’t perform the unload automatically.</p>
<p>This usually happens due to a <strong>malfunctioning or improperly calibrated SuperFINDA sensor</strong>.</p>
<p>Another potential cause could be if the <strong>filament was inserted</strong> into the selector manually, <strong>bypassing the menu/buttons</strong>, or if the printer was restarted during a load/unload operation before it was completed.</p>

<h3>How to fix it?</h3>
<ul>
<li>Verify there is<strong> no filament in Selector</strong> and <strong>SuperFINDA sensor isn’t detecting a filament.</strong></li>
<li>If there is a filament loaded, unload it manually or clear the sensors from anything that caused it to trigger.</li>
<li>If filament is loaded, unload it manually or clear any obstructions triggering the SuperFINDA sensor.</li>
<li>Verify the proper <a href="http://help.prusa3d.com/ja/article/finda-setup-and-troubleshooting_2250">superFINDA calibration</a>.</li>
<li>Use only the menu on the printer to load or unload a filament during regular use. </li>
</ul>
<p></p>


Unload manually #04506 (MMU)

<h3>What happened?</h3>
<p>During Filament loading, either to the MMU unit or to the Nozzle, if the filament does not reach the  SuperFINDA or is not detected, the printer will show an error.</p>

<h4>Assembly</h4>
<ul>
<li>Check if the filament has been grabbed by the idler/pulley. In case it has not, the filament is too far back.</li>
<li>Make sure that the two spring screws on the sides of the MMU unit are properly tightened.</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>Go over the assembly manual and verify if the barrel is in the correct orientation.</li>
<li>Check the pulley gears for any filament remains, and make sure that the teeth are clean.</li>
<li>Check that the corresponding pulley inside the MMU unit is properly aligned with the filament and is clean.</li>
</ul>
<h4>Selector</h4>
<ul>
<li>Verify if the selector is in the correct position for the given filament number. After several unsuccessful retries, the selector will re-home.</li>
<li>Check the selector for any filament remains and filament strings accumulated.</li>

TMC driver error #04321 (MMU)

<h3>What happened?</h3>
<p>Before it can align with any of the filament positions, the selector on the MMU unit needs to be “homed” to determine its position. For that, the selector moves from one end stop to the other while measuring the distance between them. The selector will home after the unit starts up, has been reset, or after another error occurred.</p>
<p>In case the Selector can't find the first homing endstop, or the distance between the endstops differs from the expected value, the printer will show this error.</p>
<p>Distance between the Selector endstops: 75mm<br />Allowed deviation: 3mm</p>

<h3>How to fix it?</h3>
<p>The selector might not move due to obstacles, debris, or remaining filament in its way. Before proceeding, make sure that the path of the selector is clean, and that any filament that has been cut by the selector blade is removed.</p>
<p>Clean also any filament that might be under the selector in the pulley body.</p>
<h4>Clearing the Selector</h4>
<p>Open the front Festo fitting to check the Selector.</p>
<p>If there is filament sticking out from the front PTFE tube, or sticking out from the MMU unit into the selector, take an Allen key to push the filament back.</p>
<p>If the selector has tried to move with the filament still inside it, turn the printer off, and manually turn the motor threaded rod until it aligns with the pulley body and you can pull the filament from the back of the MMU unit or push from the front of the selector with an Allen key. After that, <a href="http://help.prusa3d.com/ja/article/finda-setup-and-troubleshooting_2250">adjust the FINDA height</a>.</p>
<h4>Assembly</h4>
<p>In case the Selector is clean from filaments, check the following items in the <strong>MMU unit assembly</strong>.</p>
<ul>
<li>Verify if the <a href="http://help.prusa3d.com/ja/article/finda-setup-and-troubleshooting_2250"><strong>SuperFINDA</strong></a> sensor reads correctly.</li>
<li>The <strong>trapezoid nut</strong> on the selector motor might be loose or offset to one side. Remake the <a href="http://help.prusa3d.com/ja/guide/6-pulley-body-assembly_328918">Selector motor installation</a>.</li>
<li>The <strong>bushing tubes</strong> should be flush with the body of the Selector.</li>
</ul>
<div class="tip-callout">Both bushing tubes and the trapezoid nut are self-lubricating. Do not apply any lubricant to the trapezoid nut.</div>
<ul>
<li>The selector motor<strong> </strong>must not be loose on the MMU unit body. The top corner screw should be tightened slightly looser compared to the other two. The two screws should be tightened evenly. Remake the <a href="http://help.prusa3d.com/ja/guide/6-pulley-body-assembly_328918">Selector motor installation</a>.</li>
<li>In case you have printed the parts yourself, check if the <strong>printed parts</strong> do not have any surfaces that are lifted.</li>
<li>Especially the <strong>first time</strong> you are using the MMU unit, verify that the motors are connected in the correct order.</li>
</ul>
<p></p>


Selector cannot home #04115 (MMU)

<h3>What happened?</h3>
<p>After a startup / restart, the MMU unit performs a self-test. 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 the pulley motor TMC driver might not behave correctly, this error is shown.</p>
<h3>How to fix it? </h3>
<p>- Make sure your MMU3 unit is correctly assembled with the PD-board addon attached.</p>
<p>- Verify all the cables are in good condition and the connections are stable. <strong>Do not move, connect or disconnect the cables while the printer is on!</strong></p>
<div class="tip-callout">If the issue persists, contact support.</div>

MMU Selftest failed #04305 (MMU)

<h3>What happened?</h3>
<p>The selector on the MMU unit needs to move or re-home but a filament inside it is detected unexpectedly by SuperFINDA sensor. The selector can’t proceed because there might be filament in it.</p>
<div>
<h3>How to fix it?</h3>
<p>It is possible to check the FINDA status either by checking the light on top of it or on the LCD.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/02/35c472d5ac3ff43a_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Inspect FINDA #04107 (MMU)" alt="" width="400" height="300" loading="lazy" /></p>
<p>If there is no filament under the SuperFINDA sensor but its status is still 1, check the Selector for any leftover filament or debris.</p>
<p>If necessary, recalibrate the <a href="http://help.prusa3d.com/ja/article/finda-setup-and-troubleshooting_2250">superFINDA</a> by following the <a href="http://help.prusa3d.com/ja/guide/10b-mk3s-setup-and-calibration_334155">assembly guide chapter to re-calibrate the SuperFINDA sensor.</a></p>
<p>Clear the selector from any filament or debris causing the SuperFINDA sensor to remain triggered.</p>
</div>
<p></p>


Inspect FINDA #04107 (MMU)

<h3>What happened?</h3>
<p>The printer is trying to initiate communication with the MMU unit, but there is no response.</p>
<h3>How to fix it?</h3>
<p>Check the following:</p>
<ul>
<li>Make sure the MMU unit is present on the printer. If not, either connect the MMU unit back or turn the MMU off either by selecting Disable MMU or in the printer’s menu.</li>
</ul>
<div class="warning-callout">Do not move, connect, or disconnect the cables while the printer is on!</div>
<ul>
<li>Verify all the cables are connected properly. Do not move, connect or disconnect the cables while the printer is on!</li>
<li>Verify all the cables are in good condition and the connections are stable. </li>
<li>Make sure your MMU3 unit is correctly assembled with the PD-board addon attached.</li>
<li>Make sure you are using the correct up-to-date <a href="https://help.prusa3d.com/downloads">firmware</a> for both the printer and the MMU unit.</li>
</ul>
<p></p>


MMU not responding #04401 (MMU)

<h3>What happened?</h3>
<p>The filament has been ejected to the front of the MMU unit so that you can remove it.</p>
<div class="tip-callout">This feature is handy in case you are using the Spooljoin function. A depleted filament might be too short in order to be removed easily from the back of the unit. By ejecting it to the front of the unit, you can easily grab it and discard it. </div>
<h3>How to proceed?</h3>
<p>Remove and discard the ejected piece of filament and hit the button on the LCD screen.</p>
<p>If you accidentally triggered the eject function, push the ejected filament back into the MMU unit and make sure it isn’t protruding out of the short front PTFE tubes - so that the selector doesn’t jam later on.</p>
<p></p>


Filament ejected #04507 (MMU)

<h3>What happened?</h3>
<p>When the MMU unit unloads a filament from the extruder, the filament sensor inside the extruder should stop detecting the filament. In case it does not, this error appears.</p>
<div class="tip-callout">If there is an issue with unloading, the MMU gears might grind the filament. In case this happens, cut off about 40 cm at the of the filament, otherwise, errors might happen later.</div>
<h3>How to fix it?</h3>
<p>Check the PTFE tube that leads from the MMU unit to the extruder, and see if the filament has been unloaded or not.</p>
<p>In case the filament has been unloaded, but the printer shows this error, remake the <a href="http://help.prusa3d.com/ja/article/ir-filament-sensor-calibration-mmu2s_2245">filament sensor calibration</a>. </p>
<h4>Extruder</h4>
<p>In case the filament has not been unloaded, make sure that the nozzle is heated for the filament you are using. Then open the Extruder idler screw and the Festo fitting on the top of the extruder, and manually pull the filament. Note that some force might be necessary.</p>
<p>On the MK3S, check the <a href="http://help.prusa3d.com/ja/article/checking-re-aligning-the-bondtech-gear-mk3s-mk2-5s_133176">alignment of the idler door and the Bondtech gears</a>. On the idler door, check if the gear is moving freely and that the shaft is connected to both sides of the plastic part.</p>
<p>Make sure that there is no debris or pieces of filament in the idler door or extruder gears causing the filament sensor to falsely trigger.</p>

<h4>Filament</h4>
<p>Check that you are using the correct settings for your filament with the manufacturer. Filaments that have a lot of stringing might cause the filament to jam.</p>
<p>Before starting the printer operation again, make sure that the filament is straight and cut into a sharp tip, and that there is no damage on the first 40 cm of the filament.</p>
<p>In case the issue continues to happen over multiple unloads, check the <a href="http://help.prusa3d.com/ja/article/clogged-nozzle-hotend-mk3-5-mk3s-mk2-5s_2008">extruder for clogging</a>.</p>
