Hello everyone,

After a million mistakes I learned from, I finished my first Table top CNC machine that I built from scratch and it works perfectly. Nevertheless, I am still a complete newbie.
Now I got the CNC bug, and I want to continue upgrading my creation. I recently purchased a chinese CNC spindle motor, and I would like to integrate it to the controller. I am currently using a HobbyCNC EZ board, which does its work just fine, but it does not have a spindle control output. I see a bunch of chinese made boards with a spindle controller output but I see that they only control low DC motors and the quality is far from being ok.
My motor is 110V, so I am looking for a controller board that can drive the steppers, control and drive the spindle motor.
Can I just use a regular on/off switch with a variable power supply to adjust speed?
Can I use a relay connected to a low DC spindle output to drive the AC motor?

Pictures of my little CNC monster to follow.

Thanks,

Gustavo
