I am back again as the homing once again stopped working. Again when I home the machine hits the limit switch for Z and then begins to move across the X while starting to Y. However, I have noticed that for some reason only the left side of the Y moves and the as if the right side has stopped. If I Home again it continues to do the same thing and appears to get extremely out of sync/square. Any suggestions on squaring the Y or why the Y limit switch would be triggered on only one side which is what happens after it stops, shows Y has ht limit. This issue is getting a bit old and hope I can get a permanent solve.
