I saw that and set it to RPM control (also taking note of Terry Jones’ marlin fix to get that working here Control spindle RPM through RAMPS). I just need to figure out what the best way is to set the maximum output to 10V, as the spindle’s controller takes 0-10V.
I’m not sure if I should be setting the maximum RPM in marlin 120% (12V/10V) higher so it interprets the controller’s maximum as lower, or if I should set marlin to the actual max and offset Estlcam’s gcode output somehow. I’m not sure if that made sense, I but can reword it lol.
