Measuring volts from the pots on the stepper drivers to any ground with a multimeter (I use the outside part of the USB plugged into the board) gives you a number that represents the amperage sent to the motors during operation (I believe 0.1 volts is 1 amp, not sure on this). You should be able to run them up to 0.4 without any active cooling assuming no enclosure. If they're higher than that, try turning it down and see if that helps.Quote

My only thought is that some of my Polulu stepper driver heatsinks are getting rather hot to the touch, and I don't have active cooling in place. Could the X driver be overheating and stopping at some point, causing the offset?
