MPCNC with ramps 1.4
I know the dreaded laser control questions…
I have a Elekslaser 2500mw 3 wire unit and i am curious if everyone is leaving the ramps configured as EFB or are you changing to SF mode for specific spindle or Laser controls?
second question is in regards to speed control for my spindle, it has Mach3 speed control (10v pwm)
has anyone done this native on the RAMPS or are we needing to build some sort of 10V control circuit to do this?
