Matt,
PC-DMIS will allow you to set the speed in mm per second. You need to go to options/setup/CMM. You will find a box marked speed. You can enter a variable that matches the speed capability of the CMM. Unfortunately for me, the LK G80C is a slower machine. I have set the axis acceleration up to 500 on all axis, but there is no difference in the speed, or acceleration. I guess now would be a good time to hit the company up for a new CMM. Maybe a B&S Typhoon.
