My build based on this:
- http://www.prusamk2.com/haribo-3030-extruded-aluminum-prusa-i3-mk2-build/
-
...Plus https://github.com/PrusaMK2Users/3030_Haribo_Edition/tree/master/STL/optional
And also on Tom’s 3D work:
- https://toms3d.org/2017/02/23/building-cheapest-possible-prusa-i3-mk2/
You can use end stop switch first, there are holes for them on the X and Y, same as the Prusa.
For Z auto-leveling, because of the glass surface of the Ultrabase, I have used a BLTouch original.
For assembly, I mostly referred to Prusa MK2 kit manual:
- https://manual.prusa3d.com/c/Original_Prusa_i3_MK2_kit_assembly
Except for the Extruder assembly wich is a mix between MK2 and MK3:
- https://manual.prusa3d.com/Guide/5.+E-axis+assembly/510?lang=en
Also, I have used Marlin 1.1.9 and customized it for the printer, if you need the settings, ask me and I will give you some of my settings for you to configure your own Marlin, you should do this anyway it's a good way to learn.
I have bought some 3030 aluminum extrusion from a local shop and cut them to length from the instructions of www.prusamk3.com:
Clear anodize 3030 Normal Rigidity Type extrusion
- 3x 354mm
- 2x 320mm
- 2x 330mm
I have redone some parts in Fusion 360 to accommodate my 90 degrees angles that I used to assemble my 3030 frames instead of having to thread the ends of the 3030 and drill holes precisely in the 3030 to fix the Z frame. This way you can adjust the position of the Z frame. So there is a 90 degrees angle behind both Z motors supports, and you use a screw through the Z motor support into the 90 corners instead of a set screw.
I also had to redo parts of to have room for the Z motors adapter to clear the X gantry.

Finally, a bit of warning, if you attempt this build, make sure you are following every precaution you can, and make sure you know what you are doing, you are dealing with High
