I have recently run a bunch of parts that required 5-8 toolchanges each. The job went over without a hitch. When I started the machine a couple days later the ER3 light is on. I tried deleting all of the tools, and zeroed all pots and the spindle tool. I can not get the light off. I've tried a manual toolchange through M31, everything works. I can zero all axis. I have no clue what the problem could be? Any suggetions would be greatly appreciated. I have a Fanuc 6m control
Thanks!
