So I fix one wire. Then I do about 15minutes of milling, then the x-axis starts shuddering and screeching again. Yep another wire has gone! It’s not my soldering job from my first repair, but another original wire. I think I’ll just avoid future problems and just re do all the wiring myself.
Which makes me wonder if it’s worth taking some of my models, that are waiting to be milled, and send them to shapeways, in order to get anything made.
