Hi and thanks in advance.
I badly need help in tracking down a controller for the 3040 CNCEST 3 axis router machine.
Mine has suddenly developed a strange fault: 3to4 minutes after starting its run the operation stops. The power that drives the machine goes off, but not totally, the spindle keeps running.

Does anyone know how difficult it would be to build a new controller, or source an equivalent one?

Best regards,
