I think the for loop (i=0..4) on extruder 0 is not supposed to be there in ISR(TIMER0_COMPA_vect) in steppers.cpp, which then causes issues with the Advance algorithm putting 4 steps worth of plastic down each time the interrupt is called.

I'm guessing it maybe an overhang from initially using a for loop for multiple extruders and then changing to #ifdef's.
