  • thought that the g540s controller was replicated by the arduino and the two would clash. I guess I can just breakout the STEP/DIR pins from the DB25 input and hook those directly to my arduino? Wire up the relays/psu/vfd as required and go?

  • would that driver work for driving 4 steppers? bipolar parallel 2.8A/4V each. My PSU is a 48v/12.5a model. I have a geckodrive g540 but I’m trying to control my DIY CNC machine from firefly/grasshopper (an arduino plugin for rhino - cad program)
