Solved my temperature fluctuation issues

The temperature sensor in this pack resolved the random thermal runaway errors I was getting. Very stable readings now during long prints.

Perfect replacement for my A1 mini

My original extruder gear started slipping after heavy use. This kit fit perfectly and the new bearings are incredibly smooth. Print quality is back to normal.

Great value for a maintenance kit

Instead of buying a whole new hotend, I just replaced the worn-out gears and bearings. Saved me money and took only 20 minutes to install.

Fast shipping and exact fit

Arrived quickly and everything fit without any modification. My A1 is running quieter than ever thanks to the new bearings.

Good quality, instructions could be better

The parts themselves are excellent quality and match the OEM specs. However, the installation guide was a bit vague. I had to watch a YouTube video to get it right.

Solid components

The metal quality on the gear set is impressive. One bearing was slightly tight out of the box but loosened up after a few minutes of operation.

5 FAQ

Q: Do I need to recalibrate the printer after installing these parts?

A: It is highly recommended to run a flow rate calibration and check your pressure advance settings after replacing extruder gears to ensure optimal print quality.

Q: How often should I replace the extruder gears?

A: Gears generally last for several hundred kilograms of filament. You should consider replacement if you notice consistent under-extrusion or visible wear on the gear teeth.

Q: What tools are required for installation?

A: You will typically need a hex key set (usually 2mm and 2.5mm) and a pair of tweezers for handling small components like the sensor wires.

Q: Does this kit include the heating element or just the sensor?

A: This specific kit includes only the temperature sensor, gear set, and bearings. The heating element and heater block are not included.

Q: Are these parts compatible with the original Bambu Lab A1 as well as the Mini?

A: Yes, this kit is designed to be fully compatible with both the standard Bambu Lab A1 and the A1 mini models.
