This is one of my 4 axis stepper motor board revisions.
The goal design is to provide a simple, low-cost CNC controller for smaller "desktop" CNC-machines of the Sherline or Taig variety. This is sort of defined by stepper motors that need no more than 2 amps for each coil. The goal is to support either a parallel port or an RS-232 interface.
The following documentation is available:
- Design Notes
- The design notes for the motion controller board.
- Circuit Schematics and PCB
- The circuit schematics and printed circuit board layouts.
- Firmware
- The firmware for the microcontrollers.
