Spindel Control? using mach 3 signal on power supply

[dominic666 (Anton)]

Hello people !!! Sorry maybe the topic has already been.
In general, I have such a power supply unit and a spindle of 500 watts. On the unit itself there is a signal mach3.
Please tell me how can I use this to control the spindle

Somewhere I remember there was a topic using D9 output

What control board are you using? Are you using Ryan’s firmware version of Marlin?

This topic might help you a bit.

Control spindle RPM through RAMPS

I’ve ordered 600W spindle with this 600W power supply: Wow! That’s a big link! Hopefully it will get you to the item in question. There is also a picture of the power supply attached. Potentiometer (speed governor) comes in the package so some control of the spindle speed is possible and thing can be connected to the MACH3 controller so PWM speed control is also possible. Since I’m a complete noob regarding RAMPS and cnc controllers, could someone explain to me how could this be connected …

I should just turn the spindle on and off
