Another extruder jam story

I had a failure to retract filament on my P1S yesterday while using the AMS and PLA
I couldn’t pull any tubes off meaning the filament was jammed in the extruder.
I had to remove the hot end, the sliding part just above the extruder and then the extruder off. I didn’t want to cut the tubing.

Remove tension and took cover off the extruder but that’s about as far as I could go. Main drive gear would not come off. Filament was stuck between the two filament drives.

Not wanting to give up I carved one of those push up knives to about 5mm wide. Sharpened a squared up tip and heated the tip with a lighter. There is just enough room to get the knife in between the drive rollers and carve up filament. Then remove the yellow drive gear and clean everything out.

From what I can see if filament flares (expands or gets chewed up) in that drive section then the filament isn’t going anywhere. First time this happed.

dean448 great video on youtube for steps on getting tubes off…Mine is doing the same. Also clogged and chewed up around the gears.

I have had my machine for 2 weeks and now clogged for the 3rd time. I am getting ready to take it apart again for the 3rd time to try to get it running again. I am so discouraged and my husband thinks I bought a POS…Someone please explain to me why this is happening. I haven’t changed anything on the machine it is as it came. I have had a few successful prints, ran out of filament on a print and was clogged, Now 2 days in a row after that first clog, it keeps clogging. I am so frustrated! Ready to return this machine! I had Bambu black PLA, .04 Nozzle. Printed the Bambu silk thing hand without a hiccup between the 2 clogs. I am going to try leaving the top and the door open. I hope this fixes this issue. Any other idea’s appreciated and thank you.

You should always print PLA with the cover off or lifted. It was only possible to print PLA closed up with the cool plate which is no longer available. Using a PEI sheet at 55 deg will cause clogs after a few hours of printing.

Absolutely this is temperature related. The filament can’t soften in the extruder area. This is a new filament for me and I’m not disciplined about door open or closed. I’m using a cool plate for PLA but don’t think that has anything to do with this.
So I guess I’ll have to keep the door open when printing PLA in the future.

Thank you so much. Going to be unclogging here shortly. Been dreading it and putting it off.
