| + | Faults that trigger FAULT MODE: | ||
| + | * Overcurrent (Adjust current down a little) | ||
| + | * Overtemperature (Adjust current down a little, improve cooling) | ||
| + | * Short circuit (Check wiring, Check motor) | ||
| + | * Low Input voltage (Check Power Supply) | ||
| - | Make sure to set grblHAL settings (CONTROL > Grbl Settings Tab) | + | If you encounter a Driver Fault: |
| + | * Turn off power | ||
| + | * Resolve the issue | ||
| + | * Give the drivers a few minutes | ||
| + | * Turn power back on | ||
| + | * Note: The FAULT will persist until both cleared, and power has been turned off and on, to protect the stepper drivers | ||
