I know i have seen this answered before, but haven't been able to locate it. sorry for the repitition. But, when i set the motors, and use the jog buttons they work fine, i have set them a little slow for what they can run. when i save and go to the main screen and jog from there or try to run simple program, they are running way to fast and skip pulses,......i have changed the absolute, incremental, i/js and no help....you have a good forum, lot of good people. I am glad to be associated with it.
