It is a pity that my Mach3 computer has been on furlough since March and lies idle in a cupboard awaiting rebuild.

It is impossible to trace your control box wiring as the photos have not shown us the connections of the BoB/Motion controller to the relay that switches on the spindle. Do the blue and black wires connect 5v (or Ground?) to FOR when the relay is energised? I don't know what signals the VFD needs.

You might be able to start the spindle by bridging the relay contacts, if so, then we need to go back and find where the control input for the relay originates and then how Mach3 is meant to activate it.

Can you post a clear picture of the whole of the motion control board please.

Did you get the xml file from the vendor and do you have a Mach3 profile that uses this file?

The VFD isn't setup for external control if PD01 =0. you need it set to =1

Then you must check the Output for the relay is enabled and set up with the correct pin number. Then in the spindle setup, you select this output for the M3.

When all these are set correctly it will work. If anyone isn't set correctly then it won't work.

For speed control, you will need a breakout board or controller that provides either PWM or analog spindle control. Knowing Merchant dice or Bionica whichever you want to call them this would have been a £500 extra for a £10 board which they didn't fit as standard.

If you can get better pictures of the boards then it should be possible to identify.

Jazz, I admire your restraint when mentioning Marchant Dice - Bionica. They have probably changed their name again to distance themselves from dissatisfied customers and creditors.

Agreed with pics... I'm pretty sure I've seen a photo of that board (or similar) recently - a USB controller board with a bunch of discrete optos on it. Half convinced it has the analogue output on it - but pics, pics, pics.
