I have power to the steppers, the limit switches are good, and I couldn't find any fuses anywhere to check. The motor drives each have a green light and a red light and the green lights are both lit. That's good, right? LOL
I'm wondering about these two spare chips that they sent with the laser. There's two identical ones on the main board. I hope they aren't soldered. I think if they just pull out and press in, I'll change them and see what happens. Could the problem be that simple? Does a former drill sergeant make a terrible therapist?
