Dear community,
I’m having my P1S for a week now and I printed some really nice, high quality models, until two days ago.
This is the quality I’m getting right now. Is printed on a stock P1S, with standard Bambulab PLA and default Bambulab print settings for Bambulab PLA. I’m getting alike results with other filaments.
As I’ve just got this printer i did some experimenting between the good quality prints and current bad quality prints:
- Updated printer firmware and Bambulab Studio
- Printed 1 model with PLA-CF (with the standard non-hardened nozzle and Extruder Gear
)
- Ran the manual flow and rate calibration (didn’t use the calibrated profile on this print)
Do any of you have a pointer on how to back the nice print quality?
This could be so many things. It looks too small to cause so many issues due to Flow Calibration, but there is/was an error where it would go crazy, especially when using external spool, right after calibration. The fix is to power cycle the printer and just reprint it.
It could also be some major inaccuracy, either with extrusion or with motion. Do you print with the top or door open? Any weird sounds coming from the printer? Can you detect play anywhere if you try moving the nozzle by hand (yes, I mean literally grabbing the nozzle and trying if it moves)?
I did cycle power a couple of times, and keep my top cover and door closed most of the time. I gently tried to move the nozzle by hand, it seems to fixed in place nicely.
In the meantime I followed the 1st unclogging approach on the wiki (turn up the nozzle temp and let it run for a while), that did not do anything for the quality.
Open the top or door when printing PLA, see if it helps. Could be clogging because of that.
The wiki doesn’t tell you to just up the temperature, it let’s you up the temperature and extrude, but it never fixed anything for me.
If you want to make sure the nozzle is unclogged and clean then folow the cold pull procedure from wiki
Thanks so far. I’ll give it a try with the top off and do a cold pull when once I get my hardened nozzle.
Yeah, don’t print PLA-CF with a steel one, though the Bambu PLA-CF is a very “mild” CF. Damage to the nozzle can also be not that apparent, it can literally eat it from inside.
I had these issues after a firmware update and fixed it by doing a factory reset and doing the full calibration over again.
That was worth a try, but unfortunately no change in print quality.
I’ve got my new nozzle today, and replaced it, same bad results. Next, I followed the instructions clean extruder clogs, that was a bit frustrating as none of the provided hex keys fitted the screw on the filament cutter lever. But after searching my tools the extruder came off, to be found it was clean. Printed again, with no success.
Next, I ran the manual flow dynamic calibration and the manual flow rate calibration and printed again with the calibrated profile. This time much better! The infill close to the edge is not perfect, but pretty happy overall. (For those who would like to know, it’s part of the press-to-open mechanism of my trashcan)
Now the question remains, how to fully reset to factory settings? I did a fresh install of Bambu Studio, did not save the user settings, reinstalled without cloud sync, and did a factory reset on the printer. Or was this issue not caused by my first calibration?
