Aligning the steps for the axes. Using Open Control and a Black box. X and Y went fine. Z - using the wizard a 50 mm move was only 12mm. Entered that as the recorded value. Tried again and the Z only moved 7mm. At that point things began to hang up. When trying to jog the Z I get an alarm - seems to be different, so far I have seen 144, 17, and 143. All listed as unidentified alarms (surely someone knows what these mean?) Z moves a little and then the alarm comes up. If I clear the alarm and try again I get a 'Please wait for the machine to be idle before jogging. Could this be due to a too fast attempted travel rate? Could this be due to an overheating stepper motor (motor was hot - not horribly, but hot none the less) What do these alarms mean ? At this point, if I disconnect, kill open controls, relaunch it, re-connect, I can get about a half second of Z before the alarm comes up. Then I'm stuck in 'wait for idle' mode.
