Step 21. should be here between the step 15. and step 16. Before you do the step 21. the black, printed belt grabbers outer surfaces should be sanded for easier put into the EVA back core(green part). Do NOT cut the belt, just place the belt ends into the black, printed belt grabbers. Here you could see the video about it : https://www.youtube.com/watch?v=BZQMcpAv... .

Useful comment! I also applied small amount of liquid soap on the printed parts in the bearing bushing.

Step 11. could be finished after this step 8.

Screw in a M5 Cap head screw into each free M5 square nut avoid their sliding beetwen the printed part and the extrusion.

This step should be finished before the Electronic back plate frame assembled into the printer frame.

Change the step 6. and step 7. So start with the Step 7. and then finish with Step 6, then the Z carriages wont sliding off if you turn the frame upside down.
