Would there be a way to disable or override the axis limit on the J3 motor for an AR3? I've manually clicked and moved the limit switch out of the way for the J3 motor but the program wont allow for me to jog -10 degrees after moving +10 degrees. Is there a problem with my assembly or could it be a wiring issues? I would appreciate any help that can be provided.

For the AR3 software its not as easy to adjust the axis limits. If you can use the latest software for the MK2 and then select the presets for the AR3 you can adjust the limits. I dont understand the -10 to +10 jogging issue. You said you moved the switch out of the way - was that because of a calibration issue? is it not autocalibrating? If you could send me a quick video of what you are seeing that might help.

My main issue is that the ARCS program isn't reading my positions properly and the only error I recieve is a axis limit. My auto calibration doesnt seem to work properly since it keeps grinding the motors. I've included a video of my J3 position errors and calibration process.
