Must admit, I haven't checked the software version yet.... "add that to list!"

I resoldered some target wires the other day, and for about 5 minutes T-Rex moved perfectly back and forth, but then got stuck again. It could a dicky limit switch as even though it has pressed the switch lever, it just wanted to keep going. I'll swap them around and see if the jamming issue moves with it. I'm not too confident that that is the problem, as in the diagnostic mode the limit switches when activated do show up on the screen.
