Z-axis G code not performed properly

Not sure if this is an issue with NanoDLP or the Marlin software I have on my Arduino, but:
I can move the Z-axis using the calibration commands or sending G-code through the terminal. It's been acting funny. I can go up any amount (eg. G1 Z21) but any time I want to go down (eg. G1 Z-12) it will go down the same amount it went up in the last command, regardless of the distance I tell it to go down.
It's kinda buggy. It also only accepts the negative Z command and moves once. If I repeat the command it does nothing at all. The RAMPS board replies "ok".

Probably not an issue with NanoDLP, but I swapped out my Arduino, RAMPS board, and motor controller, and tried a couple versions of Merlin, so I'm kinda at a loss.

Anyone else out there have this issue, or any have any insight for me?

Thanks,
Adrian

Re: Z-axis G code not performed properly

Maybe it has something to do with relative/absolute positioning. G90/G91

Re: Z-axis G code not performed properly

I'm having the exact same problem, did someone find what is causing it?

Edit: It was the Movement Positioning set to Relative in the drop down menu and G90 (Absolute) in the Bootup Gcode!
