3030 CoreXY Motor Shims

thingiverse

Depending on the motor mounts, the XY motors may be pulled out of alignment with the belts due to the torsional forces generated by belt tension. I had one motor that needed a thin shim behind it to adjust its alignment perfectly. This issue prompted me to design this system to improve motor mounting appearance and add adjustable capability. Be cautious when adjusting, as this shim could apply excessive force against the motor and mount, causing potential damage.
