Hello @Pure_Bulat. The removal process is a bit mystical, as it is not well documented.
Here are my observations (Moai 200, Firmware: SLA-200 1.00):
If Z Follows = 0, then the vat tilts at the end of a plane slowly down, and if it is at the bottom, then the Z-axis moves fast up to the next level.
If Z Follows > 0, then the Z-axis will descend slowly as you tilt and at the lowest point quickly up to the next level.
What’s curious: Z Follows is set to zero in the first 33 levels (turned off) by the firmware. I do not understand the meaning, why is this done?
@peopoly, is this a mistake or what is the purpose of this?
I have measured the following values:
The whole procedure is to help that the FEP foil gently detaches itself from the laser-exposed plane and does not interfere with the print object due to excessive peeling forces.
I hope this helps a bit better to understand the PM process a little better.
