I got this error today after a failed 2nd filament did load. I had never tried this before so I did know what to expect. After the 1st spool ran out I thought it was taking too long but waited maybe 5 minutes before checking. Meanwhile the P1S keep working like it had filament. I tried putting the new filament in where the empty one was but no good. Got the error several times.Here’s the error;
Please pull out the filament on the spool holder. If this message persists, please check to see if there is filament broken in the extruder (Connect a PTFE tube if you are about to use an AMS).
The two brands were Bambu and Sunlu in which Sunlu is listed in Bambu Studio, and both PLA’s too. what could go wrong.
For some reason I don’t think it is a filament jam or broken filament.
I’ll trouble shoot tomorrow but ask for suggestions. Thanks.
I have yet to use the auto reload feature and hopefully someone who has used it will comment.
That said, did you configure the Sunlu to the same material and color as the Bambu Lab filament. It’s going to read the RFID off the BL spool but it is dependent on you to set everything correctly for the Sunlu spool.
This is just me but if I was doing a print that was going to finish one spool and move to another, I’d make sure they were both BL spools so that the AMS could be read on both, in sdvace. Might be worthwhile to save the RFID from used BL filament for that purpose.
I’ve done that. Bought some other brand blue PLA and taped an old blue BL blue pla RFID to the spool.
Possibly a problem with the filament sensor at the extruder/toolhead since this error occurs if the system “sees” a filament as loaded via this sensor and it will assume that it is loaded from the external spool holder if the ams shows none loaded.
I’m away from home until Friday and undoubtedly will need help.
I was trying to run a low filament spool then have the AMS switch to the other spool. It didn’t. But, I have never tried this before and didn’t know what to expect. I waited about 5 minutes while the printer acted normal. Big mistake.
Thanks for your suggestions. It turned out to be a simple fix!
I disconnected the PTFE tube and found a loose section of filament about 200mm long that did not make it to the print head. I found nothing stuck in the head, then replaced the PTFE tube. I am printing a test piece right now and so far so good.
