I mainly do wooden things on it. Cutting and engraving.
Lately I started to do bigger things and then I realized that I have a few accuracy problems with my machine.
Squareness - There is a bit of flex in the middle bit so the tubes of X and Y can be easily go out of square. I was hoping that IE_Middle_Z_rigid_v2 will help. It improves the situation but not completely resolving .
Travel distance - I try to engrave 440mm square. I get X perfectly 440 and Y 442.3. Both have the same driver, same stepper motor and same DEFAULT_AXIS_STEPS_PER_UNIT.
Any advice will be well appreciated
