Extruder Stepper Motor Driver Fault Detected
Quick Answer
Error code E_DRIVER_ERROR on your Creality FDM 3D Printers means: Extruder Stepper Motor Driver Fault Detected. This is usually fixable — see the step-by-step guide below.
Affected Models
Applies to all models
CR-10 SECR-10 Smart ProEnder-3 S1 ProEnder-3 V3Ender-3 V3 SEEnder-5 S1K1K1 Max
Likely Causes
  1. TMC stepper driver overheating due to insufficient cooling on the mainboard
  2. Stepper motor winding has a short circuit
  3. Loose stepper motor cable connection at the mainboard
  4. Driver current set too high in firmware causing overcurrent protection to trigger
How to Fix It
1
Power off and check the extruder stepper motor cable connector on the mainboard for secure seating
2
Measure stepper motor winding resistance between coil pairs (should be ~2-4 ohms)
3
Verify driver current settings in firmware (Klipper: run_current, Marlin: TMC driver current)
4
Ensure the mainboard has adequate cooling airflow to prevent driver thermal shutdown
5
If using Klipper, check DUMP_TMC output for driver status flags
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
