Some good and bad of an update. I was able to get the axis all moving again and even made a part with the machine about 2 weeks ago. Thinking things were good to go, I attempted another part yesterday where the Y axis stalled at times and seemed jumpy. The gib on the Y axis didn't have a square shoulder for the adjustment screw to push against so I figured when the table hung out too far that it was popping out of place and binding. After grinding a better notched shoulder on it and replacing it, things worked better but only briefly. I was loosing Y axis steps and was seeing that during my adaptive roughing routine taking too large of a stepover after coming back around. So basically there's still electrical gremlins to sort out. I'm going to blame the connections at the rear of the controller box and try to bypass them next going straight from the drivers to the motors.

Here's the machine the other weekend making a sample part to weld just to see how it turns out.
