Hi Ger, I have tried out what you suggested but to no avail, however I understood what was happening and realized (and apologize) that I have misled you. I open mach 3 through the KeyGrabber in which I have a joystick configured to function with mach3. As can be seen on the attached photo, the problem (I think) is with re-assigning of the relative buttons to the new OEM buttons designated in the "Jog" tab control of 2010 screen set (as described in Mach3 macro program manual - http://www.machsupport.com/wp-conten...o_Prog_Ref.pdf ). I have no idea how I could identify their translation code so as to refer to it in the KeyGrabber, is there a way to know this?
