Some Questions

[3DCoded]

I am looking into building this for my Prusa MK3S+, but I have a few questions first: This is (will be) a custom-built Prusa MK3S+ made from the frame left over after I did the Bear Upgrade. My only significant changes were using 0.9º steppers on x and y (high torque on y) and making a custom dual extruder head.

• What parts need to be removed/modified from the original Prusa to do this upgrade (so I don't buy them)?
• Where do you buy your aluminum extrusions and DIN rails (I couldn't find the right lengths on Amazon or Alieexpress)?
• What's the status of the build instructions? I don't think I'll be able to build this without them, as this will be my first time messing with CoreXY.

I have the same 0.9º E3D high torque motor on mine too. They are work great up to about 300mm/s.

* What parts need to be removed/modified from the original Prusa to do this upgrade (so I don't buy them)?

The list available on our google doc BOM list

* Where do you buy your aluminum extrusions and DIN rails (I couldn't find the right lengths on Amazon or Alieexpress)?

Bought mine from Misumi. You can get our open-beta kit from Fabreeko. It have most of the parts you will need.

* What's the status of the build instructions? I don't think I'll be able to build this without them, as this will be my first time messing with CoreXY.

We only have a simple build log, and some live build videos on our youtube channel now.
