Light Machine Corp. Benchman XTr (retrofit)

Thanks X! I'm trying to reconnect the Hall leads and power connections for the spindle. It looks like the Hall leads went to some sort of junction board on the right hand side of the rear panel:

I've also attached pictures of main board to give you an idea of what PCB I'm working with

If the hall sensors are in the wrong order then the motor will simply not run, or will run backwards.
You can just run through all 6 possible combinations to see which one works. The drawing shows which colour is which, and I would be surprised if they were not just ABC or CBA on the connector.

Thanks for that advice, Andy. Here's the trouble I'm running into. It looks like there were several slots on the spindle drive board that had multiple wires inserted. Like a wire from the spindle's Hall leads paired with a wire from the main control board. You can see the loose wires from the main board in picture of the spindle driver board posted above. Those aren't the Hall leads. And then there's the two wires from the spindle that each terminate in a two-pin header connector (also pictured above). Not sure what those are. I really need someone with one of these machines to help me out. Thanks.

Do you have the part number of the cable on the left side of the first photo? There should be a label with the part number attached. I have some connection diagrams and can check based on the P/N.

I have attached a photo of another (differrent) installation of that speed control.
(This is not wired exactly like your machine, so DO NOT COPY)
You can see that there are several locations with 2 wires in them.
I have also attached an explanation of the connections.

This should explain the connections from the motor to the speed control as well as the connections (Halls) that go to both the speed control and the control PCBs.

Once you give me the cable #, I should be able to give you more information.

Thanks for posting that picture! Unfortunately I couldn't find any label on the cable we're talking about, just the manufacturer's number;
