New user here. A1 printer with the AMS Lite, current firmware. several flawless prints and LOVE the printer. Here’s what happened: Started a print with what was left of the spool in position 1 knowing it would run out but I was watching it carefully expecting it to then switch to spool 2 (identical filament and color) and resume the print. As spool 1 ran out after about 10 layers and pulled the tape off the cardboard core, the printer stopped and returned to home, and I watched for it to switch to spool 2, but instead I just got errors. One was an accelerometer error ( no idea what that is) and the other said tangled filament. From the A1 touch screen I tried to manually switch it to spool 2, but the load/unload/edit buttons didn’t work. At some point, it then tried to load spool 3 (different color) all on its own, so I just watch to see what would happen and as the head moved back to the project it loudly dragged across the layers that were already there, damaging the print. I ended up cancelling the print, removing everything from the build plate, clearing the spool 1 filament which by now had sucked into the AMS with the tape at the end, jamming it badly.
I can restart the project from scratch, and now I have a full spool, so how to go forward from here isn’t really my question. I’m more concerned with what to do next time. Do I just put no faith in the filament backup feature and make sure every project has sufficient filament on a single spool? Did I possibly miss a setting in Studio? I’m still learning the ins and outs of that as well. What should I be looking for in terms of how this thing should actually behave?
it sounds like the tape on the spool end caused the printer to believe a filament jam had occurred.
The error messages on the screen would have said this to you.
It is possible this triggered a situation you couldn’t resolve as the first spool would need to be removed.
You would then have been able to move the backup filament manually into the same location the offending spool came from and resume the print.
Whenever I know I’m using the end of a roll. I will check it a few times until I can grab & cut the end off…either a fold or tape. Then when the roll is done, it will switch without any issues.
That’s great advice, thanks. It would be nice if BL found another way to secure the end of the filament to the spool so this wasn’t necessary, especially in instances of overnight prints.
