AcuMotion made the MyTMill systems. The early ones were
phase drive from the parallel port, and I do not know what the
signal pin assignments were.
The newer step and directions versions used this pinout:
Axis?? Step?? Direction
? X?????? 2???????? 3
? Y????? 4???????? 5
? Z????? 6???????? 7
The older drivers were unipolar for 6 wire motors. They were half
step drivers which results in 8000 steps per inch. Later systems
offered bipolar drives but I do not know their specifications.
The MyTmill systems were delivered with their own software, but
should run just fine with LinuxCNC or Mach software driving the
parallel port.
