The original Plastic bearing did not work very well in my place. So

i got it working with LM8UU Bearings instead. But two pieces need a replacement.

You need

• 1x drawing_machine_y_end2_v3.stl
• 1x drawing_machine_z_stage_face_v3.stl
• 2x LM8UU Linear bearing
• 2x 8MM rods 60mm long( i think)

Also its essential that you run the Z stage really slow to gain momentum. In my place it works with Marlin Settings for Z stage velocity Vmax=1 or 2 at the most.
