Under the "Current Axis Setup" is the  "External Increment" and the "MaxVel in ISteps/ms" have anything to do with the motor tinning? or this only the incoming Encoder as referred to the bitmap below?

Also after I upgraded to 2.6 My arrow keys will only jog when I push the Shift key along with the Arrow key. What is up with that and when I set the hot keys I never pushed the shift key along with the arrow key so why did this change?
