Sorry if it's has been answer in the past but I've tried to setup OEM button for the X+ axis as a test and when I push it, instead of jogging while I keep button in,it keep moving until I hit ESC key or emergency stop. it won't stop when I release the pushbutton .I put 307 as OEM value in the hotkey menue. Any help please. Thanks

I took this value 307 here
