I have Mach 3 installed on two machines and the arrow keys on the keyboard will jog on my router table but they don't work with my last install on my mill computer.

Mach is working fine on the mill but I have to use the on screen MPG buttons to set up the cut and I would rater use the arrow keys on my USB number pad.

Their must be a switch somewhere that I am milling.

Thanks
Dave

Edit

OK I found the switch under the MDI tab window. Just a click and the arrows keys now work fine.

Perhaps someone knows why when I cut a 360 deg ark the machine stops and starts at 180deg on every circle?
