I’ve tried several prints now and every one of the tries to fill my entire cut area. I’ve built a 2’ X 3’ unit and when I print something, it scales up to fill the area.
I made a test file with a part that is supposed to be 350 mm wide. When I try to cut it, it is tried to cut 900 mm wide. I have been careful to make sure all my measurements at in millimeters but I can figure this out. Is there any setting in the marlin firmware that I shave changed?
I’ll using the an Arduino mega, with a ramps 1.4. I’ve added all three jumpers under the drivers for 1/32 steps.
When I generate the NC file, I view it with a CNC viewer (CAMotics) and it appears to be the right size and scale?
What else should I be looking at?
