hi,

Something that has me a bit confused, my machine will home just fine a few times and next minute it will home to the limit switch then just run back to the opposite side of the machine, I then have to restart the controller and program and rehome in order to continue use, any ideas what could be causing this issue.

Sounds like a faulty limit switch that is intermittently not closing when cleared. (if wired NC)
Work the switch manually (with your finger) slowly several times while watching the LED on the Diagnostics screen to see if it is intermittent in operation.

Just guessing,
Russ

thanks will give that a try.
