Looking good..... I started on gutting the drive side. Need to track a few more wires so I can gut the rest. Figure I would get servos, encoders, and limits hooked up first then track down the spindle. After that start on the tool changer.



Trying to decide if I need this unit or not.

There are the two large 3 pole contacts in the drive side enclosure. I seen you removed the relay board that was over them. What did you do to make the contacts work again? I have been chasing this issue for a couple hours and I can not find any information on those contacts. My goal was to use the relay board. but again no information so I am resorting to removing the relay board.

I managed to get the original relay board working so far. Took some searching with my multi-meter. Now those contacts work when triggered.

Working on the lcnc install now. I am following this build from this thread for lcnc on mint.

I will update with results.
