Good upgrade

Installation took some time but works well. Had to adjust the motor current slightly but prints are much better.

Perfect fit

Mounted on my Ender 3 without issues. All holes lined up and the wiring harness was long enough.

Solid construction

Metal parts feel durable and the heatsink is adequate. No overheating issues during long prints.

Great for TPU

Finally printing flexible materials without jams. The direct drive makes a huge difference compared to the bowden setup.

Heating slow

Works but takes longer to reach temp than stock. Maybe my power supply is borderline. Prints are good once heated.
