Replacement Tips

1. Rule out a clog first – A partial clog can cause skipping/under-extrusion even with a good motor.

3. Take photos of wiring – Photograph connector placement and cable routing before disassembly.
4. Use official guidance – Start from the A1 maintenance page for safe toolhead access.

FAQ

Q: Is this compatible with A1 Mini?
A: Yes. This motor is listed for A1 and A1 Mini.

Q: Do I need to recalibrate after replacing the extruder motor?
A: Usually no. Run a filament load/unload and a small test print to confirm consistent extrusion.

Q: My extruder clicks—does that always mean the motor is bad?
A: Not always. Clicking is commonly caused by a clogged nozzle, excessive backpressure, or incorrect temperature/settings.

Q: Does this include the extruder gearbox/gears?
A: No. This is the motor only unless the package contents indicate otherwise.
