I had a bad board but the VFD I have was not well documented. All working now. Traveling now but next I can get you some hookup info if you haven't figured it out.

Which is what I have been saying... I don't know how to set up Mach3 to pass the signals I need through the BOB to trigger the output I need to drive the VFD. Ports and pins. If it was well...

I don't think it's a "bad" vfd. Actually I bought a nice ER20 2.2KW spindle and that was the 2.2KW VFD that was in the bundle. VFD is labeled A2 Series. It seems to have all the same functionality of...

I can get the relay to latch on the BOB and get the spindle to run sort of but I don't understand the settings, ports and pins, no speed control certainly and not turning on and off properly. Tried a...

Oh and one last thing the VFD has three input terminals for speed control (frequency) input. 0-10V, 0-5V, and I think 0-200ma I think. The manual is pretty clear that those are all speed input ports....

The BOB I have has input voltage pins labelled 12-52V. I brought each function of the board back one at a time. X Step and pulse Y Z A. This was using only the USB +5v input without the higher...

Due to a spindle upgrade I am back up against the wall of setting up a spindle with a VFD. The VFD spindle were an ebay combo. Seems nice enough quality. I have installed...

I believe my question is whether the relay is a dry switch or is it powered internally from the breakout board? In other words do I have to provide input power somewhere to provide power for the...

Here are the two breakout boards I have to swap in to get the relay to control the spindle. The three relay one has a separate 15-32v input. The single relay one doesn't.

Have a 4'x4'x 6.5"Z router. Generic DIY build with aluminum extrusion, steppers. All works well. Have 2.2KW water cooled spindle and VFD. Just baffled by the almost completely confusing wiring info...
