Z Wobble with 2 Independantly Driven Z Motors
-
Hi,
I recently reworked by DBOT to try out bed leveling via a 3 lead screw setup.
Having some problems in the past with lead screws driven directly from the stepper motor shaft on this printer I mounted the lead screws using common lead screw bearings and connected the motors via belts.
Very happy with the result.

Meh. False alarm. On careful remeasurement of the DXF files the base plate for the motors is wider than the main frame, giving the impression the rods are 0.3mm too tight when checked with the vernier. Investigation continues, but a z motor mount that allows me to adjust the centre of the z motor a little can't be a bad thing. Something is positioned wrong, just can't see what yet!
