The problem is with your flippy mod. You need a pull-down resistor on the input to the FET that enables the stepping past track 0. The line floats when powered externally with the SCP not connected and this will cause a problem for drive electronics. Add a 10K-47K resistor from ground to the pin 33 input and that will solve the issue. I had to do the same with mine.
