My router came with this breakout board. Not quite seen in the photo, it has its own power supply attached to terminals to the right of the USB port. My question is, do I still need to connect the usb power

I believe that BOB needs 24v to run the relay. See link for a wiring diagram. I've seen that BOB referred to a "China BOB" on forums.

Thats a very common board.You may find an answer on this forum or you may find a few videos on youtube.Is there a particular reason why you chose Mach3?Its quite old and has been superseded by Mach4.
According to postings here on cnczone Mach 4 has more problems than Mach ever had or will have.
In order for the inputs to work, you need a 24V power supply in addition to the 5V supplied by the USB cable.
IIRC you can also use the 4th axis output if only using 3 axis for VFD on/off. using the open collector Step pin and assign it in Mach3. This avoids using 24vdc

That makes me really glad I went with LinuxCNC.Quote:

Also I have posted a picture of the old Ah Ha control box. I have no idea what to do with the settings on the front, I have assumed that the previous operator had everything set up for these motors...Quote:
