Hi Zoltan
I took a look at your XML file, The only thing I see is your X axis is set in Motor tuning, To X 44, 12000, 500 and A is 2000, 120, 4.
I think A is set to default settings, Probably whats Wrong.
I've never used pin 1 for motor output, I Think it was used for printer strobe, Just shied away from it, It may be fine though.
Most use X- 3, 2, Y- 5, 4, Z- 7, 6, A- 9, 8.
Try this XML,
Hope this Helps, Chip
