I am having a problem with my 1.1 machine trying to calibrate the platform.
When I try to calibrate it, the platform and vat does it's thing, then the platform goes down to the calibration position and I can hear it activate the bottom switch. Then, I tighten the screws and click on the next step to raise the platform. It won't raise.
I have to manually turn the lead screw about 1 turn, then, it comes off the switch and goes up. So, effectively, I can't calibrate the platform correctly.
What would cause this to happen.
