One thing that could be a factor I suppose.. I am using the probotix 40v system, it uses a sla7078mr stepper driver. There is no shielding on the cables to the motor, and whenever I am routing plastic, if I run the vacuum too close, static discharge does something somewhere, and the drivers, or something fritzes until I cycle the power.
If indeed it is missing steps, I find it hard to accept that it is from overpowering the system. 40ipm in plastic with a .125" bit at .2" depth per pass isn't much.
