I have been tuning my motors for the last couple of days and having some success, except I really have hit a wall with regards to Kflop disconnecting from my computer when moves of a certain size or speed are sent to the board. I am using a Snapamp 1000 as an amplifier, and I am currently running two DC servos (MCG 1D-3303). Things seem to be going fine until I reach a certain threshold, usually a size move of 100000 or more and velocity over 80000. I suspect that the motor leads are somehow interfering with the USB, but I can't seem to sort it out. The motor cables are shielded and grounded to the control cabinet. Any help here is greatly appreciated.
