After working flawlessly for months my AMS have started acting up. I was running a 10 hour print with the remaining 10% of a spool and then with auto renew (or what it is called) setup to switch to a new spool.
The print goes flawlessly until the first spool runs out, the AMS loads the new spool and continues printing (I witnessed this). But then after a while when I check on the print again the toolhead is a good 10 layers above the print with nothing coming out of the nozzle. I open up the AMS and nothing seems to be stuck. And I also do not see the AMS pulling more filament which I normally can see every ~10 seconds.
I have opened up the AMS to see if the is any filament stuck in any of the tubes and nothing was stuck. I tried changing AMS slot for the next print but I get the same issue after a few layers.
I’m using Elegoo spools in the AMS. And my first thought was that the spool was “slipping” but when I opened the AMS the wheels never turned so I don’t feel like that was the issue after all.
Have anyone encountered something similar? I don’t really know what to look for or what to search for (here or in the troubleshooting guide).
Thanks in advance
