CNC Controller Board
With removable fuses
| Parameters | Logic high levels should be greater than 2 volts. |
|---|---|
| Logic low should be less than 1/2 volt. | |
| Step pulses are active low. | |
| Step pulses should be at least 22 microseconds long. | |
| The lines labeled as LinuxCNC inputs or outputs can be disregarded in other systems. | |
| For use with software other than LinuxCNC, make sure your software addresses the correct I/O lines for step and direction as shown below. Sherline is not able to provide assistance for other programs. For help with the LinuxCNC software, see http://www.linuxcnc.org/ | |
| We recommend at least an 800 MHz Pentium class computer or faster for use with the frequency mode. | |
| In operation, the power to the motors will be reduced to half current after 3 seconds of inactivity. This can be changed to 1/4 power with a jumper on H1. | |
| DB25 pin out | 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 – Will reduce current to 1/4 after 3 seconds |
| H2 – Unimplemented H3 – Will remove power from drivers immediately (panic stop) | |
| RESET – Will hold the drivers in reset condition | |
| Motor Connectors | 5-pin DIN male |
| Five to 30 volts (better performance at higher voltage) | |
| 2 amp unipolar configuration | |
| 800 steps per revolution (microstepping), equates to 16,000 steps/inch with .050″ pitch leadscrew |
