P1s is not detecting filament

Bambu Lab P1 Series Troubleshooting
1

I already replaced the extruder/filament sensor. The printer does not detect the filament when fed by the ams. I can print via an ex t ernal spool as the filament is not detected automatically

I am having the same issue.

I’m also having the same issue, but I’ve tried feeding the filament from the external spool and the toolhead is still unable to detect that there’s a filament being pushed into the extruder

i reverted my firmware to 1.04.01.00 and that solved the issue

I reverted back to firmware but still having the same issue. Any other suggestions would be helpful

Did you install Something like that?

Really helps.

for me the issue was not getting the filament to the detector. the issue was the detector detecting it.i did print something similar out of pla. it broke a while ago and i never replaced it.
i previously had issues with a y splitter so i could use an external spool without taking anything apart and it was a problem. if you have one of those id get rid of it.

I’m having issues with the sensor not detecting the filament, I already changed the nozzle and hot end, and still not working.

Welcome to the forum.

Have you checked the filament sensor itself?

Here is the wiki for the filament sensor.

Hello, I am having a similar issue with my P1S and I am new to 3D printing. I have replaced the entire extruder unit, filament sensor (Hall switch board with cable) as well as the mini board with the 4 electrical connections (extruder board) in the print head but despite Bambu Studio and Bambu Handy showing the correct filament status (green dot) the P1S screen and the Panda Touch screens will not show a green dot when filament is manually inserted. I downgraded the P1S firmware to 1.07 but that made no difference. Any experience with this issue?
