Problems with Bondtech extruder

[cvt 1]

Hello, I recently purchased the Bondtech extruder, and I have nothing but problems.

I tested with the firmware attached to the brand and Marlin with the same results, changed to 1000 mh, the cure 3 and 14.5 and nothing.

Every time he wants to let loose a stream of filament and spoil the impression, it is not always in the same place.

The truth is that I do not know what to touch because I do not give with the solution.

I have a UM2 + extended, to see if I can upload photos and someone can help me.

Greetings and thank you .

Bondtech QR or DDG?

Make sure the z shaft is clean and lubricated - maybe your issue originates there.
