Happy with my old Boxford 190VMC, but would like to do some tapping on it.
at present cant reverse spindle the set up is as follows.
Spindle drive is EVD534-E LENZE the BOB is hooked up to DIYCNC Spindle V4 board, not sure what the motor is, assume its the original from boxford 450w one.
the wiring on bob is setup for reversing but when you input M3 S whatever, spindle turn on CW, when input M4 S whatever, spindle stops and starts same way CW, does not reverse.
Is there a way to enable spindle reversing on above setup? or do I need to buy a new Spindle Kit? ie spindle drive + control board + spindle motor.
