Info about the controller board.
blog posts: My basic Colinbus/Elektor Profiler,
stepper motors: ST4118M1206-A
The driver board has three ST L6208 driver ICs, in PowerSO36 packaging.
The logic input pins are TTL / CMOS and µC compatible. Pins: CONTROL, HALF/FULL, RESET, CW/CCW.
The EN pin needs special considerations.
The driver board has 3 male connectors for the controller board: HDR1 (40 pins), HDR2 (20 pins) and HDR3 (50 pins). Connection to the original controller board is as follows:
HDR1 - J3 HDR2 - J4 HDR3 - J2
Stepper motors: Nanotec ST4118 (ST4118M1206) NEMA 17 motors. Each motor is connected with 4 wires (not 6), the orange (A) and yellow (B) wire is not used. Note: X and Y axis motors are connected straight through, but the Z axis motor has winding 1 reversed. Home switches (Normally Closed) are connected at the last two pins (5 and 6 in internal connectors, 8 and 9 on DB-9 connectors).
Spindle: Ferm FCT-300
