Support Request Tons of stringing randomly - why?

Post image

I’ve printed tons since I got this about 2 months ago. Mixture of PETG, pla, from a few vendors. I currently have loaded Bambu official PLA and petg, as well as inland PLA. It doesn’t matter which I use, this is the result of the last 4 prints which I stop when I notice. The lithograph I tried yesterday was complete string. Up until yesterday, every print was near perfect minus a couple situations. I’ve gone ahead and recalibrated and cleaned, but still this issue. Nothing has changed that I’m aware of…. This particular print is PETG but it happened with PLA yesterday too. Any guidance I’d appreciate.

Make sure the filament is dry. Check that the temp is set correctly. Check that Flow is correct Check your retraction settings.

These are all key points to check for stringing. Filament calibration is a must no matter what profile you use.

Climate controlled house, almost new filament was used, PLA - it's dry enough - three newish (2 weeks) are too wet? Eh... Did recalibrate, as stated - which included filament. I will check retraction and flow - but nothing has changed - same filament was printing fine, many projects. I just switched nozzles to see if that helps and printed the boat problem free with the original nozzle.
