Hi,

I have a Chinese xyz-tech cnc machine. It worked well for 6 months but now the dsp handle is dead. I am planning to remove the handle and use a off-the-shelf parallel port interface like the CNC4PC instead.

The problem is, that I have no idea how their Spindle speed control works. There´s no wiring diagram and no manufacturer label anywhere. I tried to email xyz-tech a couple of times and had no answer. I am asking the cnczone community some educated guesses on what type of spindle control this is and how to connect it to a breakout board...or if there´s any way I can figure this out!

Your help is going to be very much appreciated!!!
