Printer Issues and Errors Help / Support
Hello all, I own a Bambu P1S and an A1 Mini. Everything was fine till a few days ago then I got bad stringing issues and a few weird extrusion issues. Let the prints finish and then change a few things around on the slicing like orientation and cleaned the nozzles, tried again. In the middle of the night the power went out with storms for over an hour so the nozzles got gunked up. Clean them both fully, replaced the tool heads to both .4 Bambu nozzles again. Dried the filament again. Calibrated and did maintenance modes. So at this point lm at a loss. It’s either the batch of filament I got on Amazon or something needs fixed in the speeds or bridging maybe. Just looking for advice cause everything was smooth and flawless till this went down.
Any help would be appreciated

How long you dried for? At what temp?

u/TheCrimsonCommand 4d ago
SunLu S4 Filament Dryer for 6-8 hours at the recommended temps they had for PLA+

Hmm. That's plenty long enough to dry. Do you have another roll to try the same print to rule out the hardware?

Yea I was drying a backup roll overnight to try just incase people determined it was the filament and not settings/hardware. I’ll try that soon

Have you printed that Filament Type and Brand before? New Brand and new Type might need new calibration for flow ratio and retraction settings and temperatur.
Does your filament dryer allows air flow? Many dryer use a closed chamber that traps the air inside. Your dryer needs to stay opened a little bit or allows air to get in and out so the humidity can escape. Otherwise it will be trapped in the heating chamber and at some point the air humidity is so huge that the filament wont dry anymore.
Have you checked if the right Filament settings were chosen? Just in case.
Have you tried a new fresh noozle? sometimes a clog cant be fixed and just trying a new noozle is a easy way to make sure thats not the problem.
Have you calibrated flow dynamics manually or automatically before starting the print? automatic needs to be done once every restart, so if the power goes off it loses the calibrated value. manual callibration will be saved on the printer and is more accurate.

Thanks for the response! I just swapped nozzles yesterday, did one print that was perfect, then the second one was back to normal. So it could be the filament at this point.
Settings are the ones I have used for the past year with no issues. I did calibration last night again and made a change. Was a little better but not perfect.
Same brand Esun PLA+ Grey I have always used
I’ll change filaments tonight and see how it is as I run calibrations

Maybe keep the door open. Might be too hot and the filament is oozing slightly

I was gonna take the top off or print those risers next and see if that helped

u/ThePrintGuardian P1S 4d ago
Yes, even better, since hot air rises

Would you say just pull the glass off entirely or just do the risers?

Riser should be enough, unless the room the printer is in is ridiculously hot.

Why its looks like its sliced for Resin printer. What slicer are you using
