EDIT: I’ve followed empireOfLove@lemmy.one 's suggestions and I have rerouted the bowden tube. Tomorrow I’ll start another print and see the results. I’ll report back.

Here’s the whole printer during that print…

…and here’s a detail image:

The printer is a Creality CR5 Pro HT running Klipper - although I doubt this is too relevant. The extruder is of the “push type” with the hotend only including the heated nozzle. Current speed is 70mm/s in the layers but at the moment of the video 35mm/s due to the top layer.

I have no idea why, with a relatively symmetrical print just this corner is so messed up and underextruded. Any idea would be nice.
