Hello,
I have a raspberry pi printer running nano dlp that is direct controlled using a stepper motor driver. my question is the printer starts the print at the top of the z axis. Which would be the furthest from the basin then moves down. do i need to invert something in a config file in the pi? honestly stumped after fixing all the other issues. If i need to attach a file please just ask.
Thanks for the help

Make the printer top-down from the setup page.

So the design i am using is GPIO controlled and not serial. I tried changing the shield axis direction from zero at top to zero at bottom but it didn't work. it just does the same thing as before when a print is started. The motor goes in the correct directions when you tell it to go up or down.
Is there a calibration process that needs to be done ? i wouldn't think it would be the motor since it is moving in the correct direction when told.
Or could it be a config file issue on the raspberry pi ? if i missed something could you point me to the right direction.
