Drooping Edges

Bambu Lab A Series Troubleshooting
1

Benchy and other items have the drooping edges as shown in the picture. This happens on edges like this. Started happening all of a sudden, I’ve been printing only a week.

Can anyone help me?

ELEGOO Rapid PETG, eSUN PETG Translucent, Bambu Lab PLA Basic Black

A1 0.4 nozzle that came with the printer

I printed the benchy with PETG in 230℃ 235℃ 240℃ 245℃ 255℃ but it didn’t help.

I also checked the fan speed, but it was working correctly (100% when printing the overhangs)

I did the overhang test print and the problem starts at right about 50 degree as seen in the picture.

Hello @Minase

This issue can be caused by 2 things:

-Wet filament: Since you are printing in PETG, it is a VERY hygroscopic filament, it tends to absorb a LOT of moisture.

-High temperatures: Many times the original profile isn’t perfect, try lowering slightly the temperatures or overhang speed.

you should probably slow it down a little too

I am in the “likely wet filament” camp.

Speed isn’t likely the cause as the test Benchy can be printed perfectly in ludicrous mode.

Thanks you for the reply!

Yes, I dried my filament and printed using an enclosure for AMS Lite. There is also a droop on the temp tower even with PLA.

But after I changed my nozzle, it might be fixed. I wonder why there was a partial clog after using the printer for only one week.
