Hello all,
I am running a prusa mendel with sanguiololu 1.3a controls. I recently wanted to switch one of my axis steppers to a more powerful stepper, and I seem to be running into a few issues. Originally I had a 4 wire stepper 1.8 rev per step, and I was going to replace that with a 6 wire stepper motor with the same 1.8 rev per step, but it was at a slightly lower current. So I disregarded the two common wires on my 6 wire stepper, found the two pairs and hooked it up. It runs almost perfect, except after a while of printing it looses its spot and then get off by about 30 steps. This is the stepper I am trying to use. I have tired flipping polarity and those sort of things, but still on a larger part it suddenly looses its spot. I am using marlin firmware. I should note that on smaller parts it seems to do fine, for instance on a 20 20mm cube.
Anybody have any thoughts?

These are nice 6 wire 1.8 degree stepper motors.
Type 103H5208-0842 or -1241 or -0841
