nanoDLP

Hi there!

I am trying to set up nanodlp for a top down printer. I found on this forum some advice that I need to put some G-codes in the "Before Each Layer" and "After Each Layer" boxes. But I can't find these boxes. Where are they?

I tried writing the code in the "Shutter Open" and "Shutter Close" boxes, but the result was that the projector didn't project anything.

If I try to use nanodlp out of the box, the "Z Axis Control" thing works (the stepper moves, although not every time), the "Projector Calibration" thing works (I can see the images being projected), but when I try printing a file it just projects the images, without any movement. That's why I researched and found on this forum that I need to instruct nanodlp what to do. It all made perfect sense, I understood the G-codes, I downloaded the patched Marlin, I saw the "Z_move_comp" responses in the terminal, all seemed smooth. But when I tried to write the G-codes, I couldn't find the "Before Each Layer" and "After Each Layer" boxes.

Could someone help me please?

Thanx
