    After selecting the Auto Home function, the extruders move correctly to the 0,0,0 Axis, when they move to the center of the heat pad, the Y-Axis and Z-Axis move correctly by 1mm increments, but the X-Axis is moving by 2mm and moves past the end of the heat pad and bumping into the Y-Axis motor. Unsure why the X-Axis is off or how to correct this?

    Moving to 0,0,0 is always correct even if the motors do not move the correct distance because 0,0,0 is defined by the endstops. The motors move as long as the axis hits an endstop not matter how far that is in reality or as seen from the firmware/motor...

    Regarding your problem, can you go to the "Control"->"Motion" menu and look for the steps per mm setting for the X axis? Whats the value?

    The extruder stops at x170, y, 100, and 0z, after its bumped into the y-axis motor. It would be easier to view a video of whats happening. When I used the move axis feature, it's when I noticed the X-axis was moving by 2mm, in the 1mm setting.
    The Xsteps/mm is +160.00
    for reference these are the other values Ysteps/mm +180.00, Zsteps/mm +0400.0, and Esteps/mm is =0414.5

    Ok. Check the X axis motor. Is it the correct type? It must be a 400 steps motor...

    I believe that may be the issue. I need to double check all the motors. I'll re-reply when I have them all checked out.

    The symptoms match if you used the 200 steps motor, it will double the travel...

    Thank you very much. I had placed the wrong motor in the rear Bowden extruder. Problem resolved.
