Z axis not moving

Hello,
I am new to the resin printer world and my experience lies with fdm 3d printing. I am currently using a rpi zero wh (it's supposed to work, but it's slow) with an arduino with grbl and a cnc shield and an lcd screen.
nanodlp runs fine on the pi and grbl works on the arduino. I can manually controll the z axis stepper (nema17) if I use this command: G1 F200 to set the feed rate and then use G1 (how ever far I want to move).
If I try to print anything, the display shows the correct image, but the stepper motor does not move. I have tried changing the steps per revolution, and putting the G1 F200 command as a before and after layer command. However it still doesn't work.
Any help on this would be appreciated, since I can't find much information online regarding nanodlp with an arduino and grbl. The tutorial videos out there all assume everything is working properly and only go over connecting the arduino to the pi.

Thanks in advance,
guy1
