The resolution is dependant on a number of factors, including the mechanism used (note that these can vary between machines) and the controller (does it do microstepping?).
To determine the resolution, I took a rough guess @ 1000dpi, then sent commands through Linux EMC's MDI console to move 10cm, using the test button to manually fire the laser at the start and end of the movement. I then measured the distance between the two points using a vernier caliper, and adjusted the values accordingly.
I haven't yet fully calibrated it, but as it stands, with my controller set to 8 microsteps, I have:
Steps/rev: 48
Microsteps: 8
Leadscrew Pitch: 38.8mm
