Step 1 Preparing MK2.5S upgrade kit

⬢Welcome to the tutorial how to upgrade your Original Prusa i3 MK2/S to Original Prusa i3 MK2.5S

MK2S to MK2.5S upgrade is no longer being supported nor sold as a kit. Please see this article about current upgrading options for MK2/S and MK2.5 printers.

⬢Prusa Researchから届いたMK2.5Sアップグレードパーツを準備してください。

The items on the picture might differ from yours.

WARNING: This assembly guide is valid ONLY FOR SINGLE MATERIAL MK2.5S!!! For MK2.5S MMU2S, please wait for the guide to be published. Different parts are needed!

Step 2 Getting the necessary tools

⬢For the MK2.5S upgrade you will need:

⬢Needle-nose pliers (1x)

⬢Allen key 2.5 mm

⬢Allen key 2.0 mm

⬢Allen key 1.5 mm

⬢Slotted screwdriver for the belt insertion

No soldering is required.

No wire crimping is required.

Step 3 Use labels for reference

Most of the labels are scaled 1:1 and can be used to identify the part :-)

⬢最も一般的なよく使うネジ、ナット、PTFEチューブなど、実寸大が描かれた Prusa Cheatsheet で、一つ一つ確認することができます。

You can download Prusa Cheatsheet from our site. Print it at 100 %, don't rescale it, otherwise it won't work.

Step 5 Printed parts - versioning

⬢Most of the 3D printed parts on Original Prusa i3 MK2.5S most are marked with their version.

⬢Cx series (e.g. C1) - those parts are printed on Prusa Research farm and are distributed with the kit.

⬢Rx series (e.g. R4) - those parts are available for download and printing by the user. They are identical to the factory ones.

Step 6 Printed parts - self printing

Before we start disassembly, you need to print all the necessary parts. If you already have the parts, you can skip to the next step.

⬢For MK2/S to MK2.5S upgrade you need to print the extruder parts, which are separated into more G-codes. Use enclosed BLACK PETG or similar material. The colour should be black to avoid issues.

⬢G-codes and STL files are available on our website: prusa3d.com/prusa-i3-printable-parts

For printing individual parts it is recommended to use Slic3r PE with 0.2 mm layer height, GRID infill at 20%, no supports!

Fan-shroud must be printed from ABS only!!! We include this part in the upgrade package.

The pictures does not represent all the parts.

Step 8 Pro tip: inserting the nuts

⬢3D printed parts are very precise, however, there still might be a tolerance in the printed part and same goes for the size of the nut.

⬢Therefore it might happen, that the nut won't fit easily in or might be falling out. Let's see, how to fix it:

⬢Nut won't fit in: use a screw with a thread along its entire length (typically: M3x10, M3x18) and screw it from the opposite side of the opening. While tightening the screw, the nut will be pulled in. Remove the screw afterwards.

⬢Nut keeps falling out: Use a piece of tape to fix the nut temporarily in place, as soon as you insert the screw in, you can remove the tape. Using glue isn't recommended as it can partly reach into the thread and you won't be able to tighten the screw properly.

⬢Every time we recommend to use the "screw pulling technique", you will be reminded with Joe's avatar ;)

Parts in the pictures are used as an example.

Step 9 How to successfully finish the assembly

To successfully finish the assembly please follow all these:

⬢Always read all the instructions at current step first, it will help you to understand, what you need to do.

⬢Don't follow pictures only! It is not enough, the written instructions are as brief as they could be. Read them.

⬢Read the comments from the other users, they are great source of ideas. We read them too and based on your feedback improve the manual and the entire assembly.

⬢Use a reasonable force, the printed parts are tough, but not unbreakable. If it doesn't fit, check your approach twice.

⬢Most important: Enjoy the build, have fun. Cooperate with your kids, friends or wives. However, we take no responsibility for possible fights ;)

⬢READY? You can start by assembling Y-axis in the next chapter - 2. 分解
