SOLVED, I had a preceding slash in my /dev/ttyACM0 line.
Pi2 -> Arduino running vanilla GRBL -> TB6560 3A Stepper Motor Driver -> Z-Axis Motor
NanoDLP works fine, and I've tried ACM0 and ACA0, but i can't move the Z-Axis using the control buttons, or the terminal.
If i connect the Arduino to GCODE sender on my computer the Z-Axis moves fine, but I can't figure out how to get it to work when connected to my Pi.
