So I’m trying to get my printer to a point where i can pretty consistently turn out high quality prints, but I’m at a point now where i get results like this. These two prints are from the same batch, same print job, and I’m completely clueless on how to fix it. I have an ender 3 v2 with a bltouch, I’ve adjusted the eccentric nuts, tightened the belts until the tips of my thumb and index finger couldn’t tighten them any further, bed is level, using hatchbox pla. I know i can do ironing to fix the cosmetic problem, but I’d prefer to fix the root issue if possible.

    Yeah that’s a pretty tight range for the bed leveling, shouldn’t be causing any issues then. OK another possibility here… the failing prints, are they on the left side, right side, one specific corner, or does it tend to move around between prints?

    E-steps varies per extruder, not per manufacturer. What they recommend will get you close but there will always be some variance. On my printer Creality recommended a setting of 93 but my measurements put me up around 98, so quite a difference. Are you still using a bowden tube style extruder or did you upgrade to a direct drive? And is your filament spool mounted on top of the printer (if so, what guides have you added for the filament path), or did you move it off to the side?

    Erg sorry, jerk is probably what you’re looking for here. It’s been awhile since I did much printing so I keep confusing the terms.

      The falling prints i think have issues in the same spots, there are relatively small patches around the print surface that don’t print very well, though they don’t seem to correspond to the bed leveling screws or anything. Now that i say that I’ll have to check that I’m using the mesh level correctly when i get home.

      I’m still using a Bowden type extruder. The extruder itself is a generic aluminum one. My filament is run out of a sunlu dryer by the side of the machine.

      I think i actually raised the jerk at one point to reduce the radius on corners, so i can bring that back down again and experiment with acceleration.
