Is there a way to recover a print when the ams says it cannot remove filament from tool head? The wiki for the error isn’t much help
Removing the ptfe from the tool head I do see some filament in the hall sensor area… the wiki recommends…
“ to remove the Hall switch holder and check if there is a broken filament. If there is no broken filament inside, please check whether the magnet of the detection switch can spring back smoothly.”
If I do this, I end up powering down the machine and losing the job
All I need is to heat up the tool head and push the filament out, but it can’t seem to do that
I am hours into a multicolor job and 85% from finish… is there anyway to get the detection switch to spring back without turning off the machine?
guess no one has experienced this. So I seem to have lucked into a “solution”.
i was frustrated with the situation (wasting a perfectly good print job) and needed to go out… So i just decided to shut off the machine, since it was keeping the bed hot at 65C continuously while in this error condition.
much later, i decided to come back and troubleshoot, first thing i did was to turn on the machine.
it told me i had a job in progress, and if i wanted to continue, this was both on the front panel, as well as the app. I said yes, continue.
it restarted the print without any issue.
i’m guessing the hall switch reset when the power was turned off, and the printer resumed like it had no issue. This sucks that the hall sensor can trip up a print.
good news - print finished
bad news - small layer shift at the place where it stopped.
I experienced, similar issue twice with one of the filaments . Ones was able to recover (not sure how ) by disconnecting AMS and using external roll loaded the filament and continued. no AMS that was on the older firmware. The second time failed and had to restart the Print Job, but a few times run out of filament on the AMS . And i disconnected it, and connected it back and usually continues the job .
hi, thanks for your comment - are you saying that you were able to restart the print job by disconnecting the AMS and reconnecting? do you do this by removing the power connection between the printer and the AMS?
yes, i will retry it this weekend to see how exactly did it , also there are two firmware versions i have been playing with and will let you know which one with , but definitely was able to continue one of the prints which was around 10 11 hours. Actually runout of filament more than once
So I just had this happen yesterday and I was 15 min off of completing an 9 hour print job. I have had the same issue of not being able to do anything to clear the filament.
I powered off and then back on the machine and then resumed the print. However, I did not realize it started printing from the external spool instead of the AMS, even though the print was entirely printed with the AMS only. So I eventually had a missing layer before I could pause the print. To fix this, I basically removed the filament from the AMS and loaded it as an external spool. This allowed it to continue correctly after the missing layer.
So after powering the machine back up and before pressing resume, I would advise to check the filament source.
Hi Jerich, Yes resume works almost always, I just did a new test with ABS, Filament finished , disconnected only AMS from the tube and the AMS cable. Important do not turn off the Bambu printer. Moved the AMS to the table made a mess with the filament as i cut to simulate. fixed and feeded the filament into the AMS . Reconnected waited around a minute for bambu to recognize the AMS and resumed using the retry no problem with out even checking filament source. There might be a few caveats, one of the time when had to take it a part a resumed from the external roll , but with out reconnecting the AMS and as Morius mentioned you may need to check the source and the type when you do that. One minor problem as X1C not always clean well the head when it happens and usually an artifact shows if especially on external wall. I have 7 rolls of PLA which breaks very easily and doing a big print(around 3Kg-4Kg, 58 parts) and decided to use only external for it as it broke a few times into the AMS and jammed 2 times once had to take it apart. But have not had any issues like that with ABS and , eASA and PLA+ good filaments.
