Hello. Recently upgraded my Prusa i3 with a Bulldog lite and J-Head Mk8.

I am going to try that next. I have applied all the recommendations in the post and the prints have improved. Going to try getting another role of filament this week. Any recommendations? I have been using microcenters filament.

I only use Microcenter filaments and actually it was my white roll from there that I have had overextension problems with. Just go buy a different color inland brand roll and you should be fine. I’ve been through 8 or so with no issues aside from my white one.

@Griffin_Paquette Thank you. Going to head over today and pick a roll.

Here is print with white filament. Definitely fling to pick up other filament this week.
