Welcome to the forum. I'll need a few more specifics about your machine. I think I can best help you via the phone. I left you a phone message to call me back.

Hi Doug,

Will the controller work with MYSWEETY CNC 3018-PRO?

I took a quick look at it. There doesn't seem to be any documentation on the interfaces. I'll assume that the motors are bipolar steppers and that they will work fine. The spindle control is through a pwm interface. There is no indication of the voltage amplitude that is required for the pwm signal. The BB controller puts out a 3.3 volt signal, so you might have to add a level shifter to make it compatible with their spindle.
