I was pretty careful and tried to keep the work raised off the table some to give me a chance to stop the mill if needed and used some cheap AL plate to protect the table most of the time. I did manage to estop several times when things when wrong, before I drove a 3/8 mill into the table during a rapid reposition where the machine somehow lost it's Z reference.....I then decided it was time to get some limits installed. |
Can a limit switch prevent the Z from going too low? It seems like it would only work if all your tools were the same length.
