Hi Lee,
Thanks for checking into it. I did retune the motors after (I set acceleration to 350 again) and followed the mach manual in sec 5.5.2 regarding retuning. When I use the arrow keys to jog or the arrows on the on screen pop up jog controls I get full speed jogging at 350IPM. Also mdi gcode commands move at 350IPM as well. It is only with the xbox controller that I get 180IPM max for jogging. It's probably a config issue on my machine or a mach bug then if your code does not factor in kernel speed. I will keep trying different things on my end. Were you able to reproduce the issue on your end? It would be interesting to see if it is reproducible on a different computer/machine. I wonder if this issue is also encountered with other pendant plugins like the shuttle pro.
thanks,
Brendin
