Ender 3 v2 filament curling after hotend upgrade

  • Hi, folks!

    Can anyone help troubleshoot my filament curling problem please?

    I upgraded my Ender 3 v2 hotend to the Micro Swiss All Metal Hotend, and my filament started curling around the nozzle right after the priming line & blob.

    I'm using the same Comgrow PLA filament as before the upgrade. Same nozzle & bed temperatures -- 200C & 60C.

    I heated and raised the nozzle up, manually extruded 50mm out of the nozzle, and there's no curling -- the filament came out straight down to the bed. I tried another print and the priming line & blob was fine, but again right at the start of the actual print brim it started curling again.

    Why would it only start curling after priming? I'm stumped, and also a bit annoyed as the hotend was supposed to be an upgrade.

    Any help would be much appreciated!
