The X-Controller has PWM and 0-10V outputs for controlling spindle speed, and there is an option in the machine setup dialog flow where I can select “Automatic” for spindle speed which I presume means that GRBL should make use of those two spindle speed outputs.
When I check those outputs I see constant 10V on the variable output and 5V @ 100% duty cycle (meaning, no pulses just flat 5V) on the PWM output.
So, here’s the question: is there anywhere in Easel where I can tell the system to slow down the spindle on a particular job? Checking the docs on the cut settings I don’t find a spindle speed option.
Should I just be using M3/M5 gcode commands to make this happen?
