No Prob. Buy a pack of these
Leads to connect your axis drivers to the board as well.
This is the board in place, I've not yet wired in the external E-stop switch as I need to find a suitable place to mount it.
Using the leads I linked to above, this is how I connected them to the existing driver wiring. I removed the forth (white) wire from the plug as I did not need it.
This is the wiring from the VFD to the board.
Yellow is X1 terminal, goes to pin 17 on the BoB
Red is the AN1 terminal, goes to 0 - 10V spindle speed pin on BoB
Black is COM terminal, goes to GND pin for spindle control on BoB
I used 4 core shielded cable for these connections, and cut out the unused cable. The shield is also connected to the COM pin at the VFD only i.e. not connected at the BoB end.
VFD programmed as per this video
I've also attached the best manual for the board I was able to find.
I think that about covers it. The Mach3 settings are as per the attached manual.
Good luck!
Edited to add: You will almost certainly have to cut a slot in the control box for the USB connection. You need to power the board with both a 5V USB lead, and a 12 - 24V supply from your control box's power supply.
