My CNC has been working very well, and suddenly stopped. Initially I thought the cause was a loose connection with the USB. I solved that, but now I cannot get the Router to work. Everything else is 100%OK. X,Y & Z all perform as required, however the actual Router is not spinning. Mach3 also indicates the expected router speed.but then nothing !!

I live in the Bristol area, and am seeking a "Hobby" Engineer, who I could seek support from. Does anyone have any suggestions to help me.

In anticipation .... thank you
