I have discovered yesterday evening that the head does not move any more in y-direction after having activated the $J Jogging in the settings. It moves as expected in x-direction but the button for the y-direction does not work.
As soon as I deactivate the $J Jogging, everythings work as expected again.
I am going to offer a guess based on the fact that my $J stays on all the time. If this is a new issue, your controller software may be corrupt. If it has always been this way, it is by design in the controller software.
my machine (Ray) is pretty new. I guess it was always like this but can not confirm it. I wonder if I shall update the firmware again ? (I did it recently when I was setting up everything).
