Started my CNC machine after a month idle time, tried to Ref All Home. The Z & Y axis move fine. The X axis moves but the slave axis A does not. If I jog the X axis both X & A move. During home the X axis will move until the gantry angle is such that it stalls and chatters. This did work previously, I tried older versions of my configuration (xml files) with no success. Looking for some direction as to what might have changed.
