DCI stepper motor driver.
Stage
The provided stage. Marked "DCI MC-001".
Bottom of stage has four holes in a 2x2 grid. Holes are tapped for 10-32 machine screws.
ID of holes is 4.15 mm.
Pitch of holes in short axis (direction of motion): 50.53 mm
Pitch of holes in long axis: 79.55 mm
Top of stage has six 10-32 holes in a 2x3 grid. Spacing in both axes is 50.53 mm.
Joystick
The stage is meant to be manually controlled via a joystick.
The joystick module is a 2-layer PCB which generates step/direction pulses using one CD4046B PLL IC for each axis. This is clearly a prototype or low-volume product given that there are at least four obvious pieces of rework on the board.
Drive
The drive unit accepts step/direction pulses on a DA-15 D-sub connector. Only six of the 15 positions are loaded, configured as follows. All signals are 5V CMOS logic levels.
| Pin number | Wire color | Function |
|---|---|---|
| 1 | Black | Ground |
| 5 | Orange | +10V power to joystick |
| 9 | Yellow | X axis step |
| 10 | Green | Y axis step |
| 11 | Red | X axis direction |
| 12 | Brown | Y axis direction |
