Same issue here,
Iam very new to the Mach-ecosystem. Iam coming from linuxCNC, machine works fine.
Then i tryed Mach3 first (demo version) and everything works fine (homing, jogging,...)
then i tryed Mach4 + Darwin:
Jogging over keyboard is possible, Inputs configured (homing and limits) but when i click on "Ref All", button gets grayed out and nothing happens.
also its not possible to switch on Mist or flooding. (outputs configured to correct pins. If i click "Toggle" in Darwin-config-outputs, the solenoid gets activated correctly)
3hours of testing and reconfiging yesterday, but couldnt sort it out.
anything else what i can try?
anything else of information i should provide?
thank you in advance.
