Hi Gang!
I'm trying to get my Prusa MK2 clone working. I have on my Z axis 8mm smooth rods and T8 Acme screws. At the top I have the bracket with a bearing to hold the threaded rod.
The Motors were skipping as I try to send it up. I am trying to manually rotate the motors (power off) and I'm binding an inch or two from the top.
Any thought on how to fix this?
At least to my eyes and a ruler they are straight.
I was thinking about removing the bearings to give the threaded rod slack? But it could be the smooth rods?
----------------------------
It seems to move fine toward the bed. So that makes me think it is not binding between the threaded and smooth rods.
