H2 V2S Revo tpu printing issue

[lowki]

Hello!

Since I replaced the original extruder of my Artillery X1 by an H2 V2S Revo, I can't print TPU.

After a few layers, 3 or 4, the filament jams into the extruder every times.
It is the same filament, same spool, I was using with the original extruder, without any issues.
I tried with different temperatures, different speeds, different retractions lengths and speeds, but nothing fix this issue.

Do you have any advice?

maybe loosen the spring pressure?
