Description
- 1x Sherline CNC Controller Board
- Logic high levels must exceed 2 volts
- Logic low levels must be below 0.5 volts
- Step pulses are active low
- Step pulses must be at least 22 microseconds in duration
- Lines labeled as LinuxCNC inputs or outputs can be disregarded in other systems
- For non-LinuxCNC software, ensure the software addresses the correct I/O lines for step and direction
- An 800 MHz Pentium class computer or faster is recommended for frequency mode
- Motor power is reduced to half current after 3 seconds of inactivity; can be changed to 1/4 power with a jumper on H1
- DB25 pinout:
- 1: Input from LinuxCNC (may be ignored in other systems)
- 2: X Direction
- 3: X Step
- 4: Y Direction
- 5: Y Step
- 6: Z Direction
- 7: Z Step
- 8: A Direction
- 9: A Step
- 10: NC
- 11: Output to LinuxCNC (may be ignored in other systems)
- 12: Output to LinuxCNC, XYZ home (may be ignored in other systems)
- 13: NC
- 14: Input from LinuxCNC, C1 (may be ignored in other systems)
- 16: Input from LinuxCNC, C2 (may be ignored in other systems)
- 17: NC
- 18-25: Ground
- Headers on PC board:
- H1: Reduces current to 1/4 after 3 seconds
- H2: Unimplemented
- H3: Removes power from drivers immediately (panic stop)
- RESET: Holds the drivers in reset condition
- Motor connectors: 5-pin DIN male
- Voltage: 5 to 30 volts (better performance at higher voltage)
- Current: 2 amp unipolar configuration
- Steps: 800 steps per revolution (microstepping), equates to 16,000 steps/inch with 0.050″ pitch leadscrew
