Ive noticed that on a few recent prints that, it looks like the nozzle clogged for layer or so..
and its noticiable weak in that spot when i remove it..

im using a .25mm nozzle with ABS and a Bondtech v2 extruder
the extruder is so strong and grips the filament so well. I doubt the cause is slippage,

seems like the hotend is clogging occasionally, not sure what i can do about this.
