RAMPS board pins vs GRBL board pins (4 replies)

I just got a RAMPS board, and loaded Marlin on the Arduino.

I want to do Laser. Can I switch to GRBL code and (LaserGRBL)? I know the RAMPS is bipolar and the GRBL has (drives) UNIPOLAR. but at the Arduino drive level, the pins could be the same, or maybe a header file can be configured on the GRBL build?

Thanks,
Alan
