ProosaXY (Prusa Mk3 CoreXY Conversion Kit)

ProosaXY is a Prusa MK3/S CoreXY conversion kit that aims to get more performance out of your 6 years old machine with the lowest cost possible by re-using most of the stock MK3/S parts.

Make sure you read the open beta kit notes.

Specs

  • Better performance (check input-shaper in pictures).
  • Triple Z (independent or sync based on controller board) 
  • Single v6 hot end (default) or mixed 2-in-1-out hot end (WIP).
  • Optional AUX cooling fan.
  • Semi-enclosed (default) or fully-enclosed with top hat (coming soon).
  • Our industrial leading SnakeOil technology 😉

Notes

  • This mod requires some drilling on the original center frame plate and cutting the original motor leadscrews. This drilling/cutting is easy enough to be done with a hand drill and a hacksaw BUT THERE IS NO WAY BACK. You won't be able to convert back to the original MK3/s machine if you change your mind later.
  • To keep the cost down and reuse old components, there are some trade-offs I made:
    • The machine is semi-enclosed by default and will need some printed panels and a top hats to fully enclose it.
    • To match the frame height, cutting the motor leadscrew and linear shafts is required.

What's in the Kit

  • All new extrusions (drilled and tapped)
  • Fastener/Screw/Washer kit with 20% extras *except for a few sizes mentioned in notes below

  • 4x 2GT 16T idler 3mm bore
  • 2x 370mm linear shaft (d=8)
  • 2x 330mm linear shaft (d=8)
  • 3x 260mm linear shaft (d=8)
  • 6x linear bearings
  • 1x Rubber tape (60x18x0.5mm)

Open Beta Kit Specific Notes

We're offering beta kits at a discounted price for customers who are willing to address the notes below during their build. These issues will be fixed in the production version of the kit.

Beta Kit - Things to FIX

  • Frame extrusions:
    • We found some extrusions in beta kits that were not cut 100% square, but are still usable. Use the included corner brackets to ensure everything lines up.
    • Check for "fence burs" in the tapped ends and sand/file as necessary.
    • Extra wrench hole in two extrusions for easier motor mount access (optional).
  • Motors:
    • Motor shafts are a little short (23mm instead of 25mm) and only make minimal contact with the support bearings.
    • Also, the support bearings may be too tight to fit properly on the motor shaft. Some sanding/filing may be necessary, or simply install without the support bearings.
  • Cut rubber tape into two strips of 5x48mm
  • DIN rails may be a tight fit. Shorten by ~1mm (if necessary)
  • Aux fan is 12v (instead of 24v) so be sure to use a buck converter or an MCU with selectable voltage

Beta Kit - Things to ADD

  • +12 m3 square nuts
  • +12 m3x25mm button head screws
  • +2 m3x30mm socket head screws
  • 24v hotend fan and part cooling fans **be sure to use a buck converter or an MCU with selectable voltage if you're re-using your existing 5v fans
  • Drill bits and m3 tap for drilling front center frame plate (optional)
    • 2.6mm drill bit
    • 5mm drill bit
    • m3 tap

We also recommend upgrading your MCU and hotend to take full advantage of the increased speed.
