Any ideas on the design of this X-Z axis?
The X axis part (Cyclone PCB factory v0.8.5) has turned to be a really challenging print. It is very difficult to get the linear bearing aligned properly: they are far from parallel and are subject to lots of effort, so they don’t slide well!!
The idea is to have the Z axis slide with a plastic guide covered with Kapton tape (or similar) to reduce friction.
The Z motor will be over the X carriage, spinning the Z threaded rod directly. The hand-drill will be attached to the same part as the Z motor.
