I recently upgraded a techno-isel lc series from stepper motors to servos (bought the whole setup from techno). The problem I am having is when a program finishes the z axis raises all the way up until it hits the limit and shuts off. The problem is not in the nc program. It happens with programs I write, and with the test programs that come with the machine. I know that the cutter should come to clearance height (.500) which it does but then it rapid feeds to the top. I am not having much luck with techno figuring this out. If anyone knows what is happening, please let me know. Thanks in advance.
