I had been having great success with my prints right out of the box with my P1S and AMS combo. I am not sure what has changed, but my prints no longer come out right. Same files I have printed multiple times are now not coming out right. Also noticed the filament poop has been kinda thicker and smooth compared to older poops from successful prints.
Did the software update trip me up. I’ve re-calibrated and also tried manual calibrations on my filaments and that does not work either.
I’m using Bambu Lab PLA Glow filament. I’ve washed the PEI textured plate with dish soap, I’ve oven dried my filaments for 6hrs at 170 degrees. I’ve checked the nozzle for clogs. Please guide me on how to solve my problem? Happy to provide more useful info just let me know what that is?
You say oven dried - gas or electric? Reason I ask is combustion humidifies the oven some and is why some cooks prefer ovens heated with fire. You’ll get lower water content in an electric oven.
About the software update - was that a good demarcation between when things worked to when they didn’t? If you had good prints afterwards, it might not be your issue.
Also, if you open other peoples 3mf files and they have different settings, and you overwrite your own defaults when it prompts you, it could be you just accidentally changed something important for your prints.
Lastly, as seasons and weather changes, ambient conditions may change. Air from an A/C register, humidity, room temperature, etc can all impact prints depending on enclosure (if present) and if doors are open.
software update, I don’t think I’ve been getting good prints since I updated
My same files were working great previously. These were my files that i created.
I’ve been using mor eAC in the home recently, and noticed the humidity level went up to 3. After oven drying and adding decessant packs to the ams and under the plate area, the levels show that is back down to 1.
Do you still have older printer files already sliced where you could print a test without having to slice again and maybe pick up any bad settings - if there are any bad settings.
With a gas oven you won’t dry as much as with electric all things being equal. You still have the heat but it’s a semi-moist heat. But if the AMS went to 1 on their humidity scale you are probably fine. I use PLA glow a fair amount here ant it behaves a lot like regular PLA for me. I haven’t had issues.
If you think you might have accidentally overwritten your defaults that used to work, you may be able to move them out of the way (somewhere safe if you have tweaked them) and start Studio. It may regenerate the stock set. Or you may have to remove and reinstall the software to get it to regenerate stock settings files. Hopefully you see where I’m going with that.
But don’t have much more to offer. Not familiar with that printer so might be off base. Might look into some of the other threads on PLA glow too - it’s abrasive and eats tubes and fittings slowly but it does. Good luck!
Thank you for your insight. I am experiencing the error with basic PLA as well unfortunately. I may try “reseting” my Bambu Studio software, or like you say un-installing and re-installing to wipe out any conflicting settings.
This means your printing too cold. GITD needs at least 5*-10* hotter temp then regular PLA. Also, increase temp 5*-10* if your using a hardened nozzle.
I am using the 0.4 nozzle that came stock with my machine. I’ve had over 50 successful prints with this nozzle and glow PLA before the failed prints began just a couple weeks ago.
from top down you can begin to see the poop change. After the glob, I cleared the nozzle and recalibrated and you can see the last one is thicker (indicating the temp is too low by 5-10*?)
GITD or any abrasive filament will eventually destroy a normal nozzle.
If you’ve done 50 prints, there’s a good chance your nozzle is no longer is a .04.
There are 2 things you can try if you don’t want to try raising the temp 5*-10*.
Replace the nozzle & test again or try a color that’s not black.
There’s your problem.
Glow is abrasive. It will chew up the standard nozzle. Should use a hardened steel nozzle.
The reason you see the change is glow has made the nozzle hole bigger.
Thank you for the guidance! I would be totally lost otherwise. I just ordered a hardened steel nozzle replacement from bambu and will follow up on this thread once I try it.
You should start a new topic and be sure to specify what brand/make/color filament, printer, nozzle, temperatures, any settings you changed that might be relevant, and maybe even provide some photos. The more you tell others that is important to the issue (which obviously you might not know up front), the better your responses and more likely you’ll get help quick. Good luck!
Since you’ve also tried drying your filaments and manually calibrating them without success, it’s definitely puzzling. Consider checking the slicing settings in your software, particularly the temperature settings for PLA Glow filament. Sometimes slight adjustments there can make a big difference in print quality.
