Re: GRBL controller 0-10v spindle
Your problem is probably ground current from the motor chassis return by using the GRBL connections.
You could start by powering the GRBL controller from the same outlet as the rest of the machine, but that will probably not solve the problem.
Powering the arduino from the PWM converter power supply could probably solve the problem. Check the maximum voltage your arduino board can handle.
The best solution to get rid of the problem is to add an optocoupler (galvanic isolation) between the output of the GRBL controller and the input of the PWM to 0-10V converter. Then you have an isolated PWM output on the GRLB controller and an isolated input on the converter. Add the optocoupler on the PWM converter side. Here is example on how to
