I just recently got the X-Controler for my X-Carve 750. It was almost done with the second cutting and I lost power. The light on the power supply was on but not on the 2 circuit boards.
I called Inventables and there is an issue with the crimps on the E-Stop Circuit. I cut the crimps off, stripped the wires, and reconnected. Everything is working now. Issue resolved, just sharing the info
