Hey Guys!
We've had to scrap quite a few prints that required the Material Manager to swap to the next roll of similar filament mid-print. However, we've found out that if we cut off the bend in the end of the filament, our Material Managers have no problem. What we observe is the bend at the end of the filament gets caught and the Material Manager's feeder will just spin out on the filament, causing a non-recoverable error (usually ER59) and scrapping the print.
It's also worth noting that we use mostly Ultimaker Tough PLA and Breakaway.
It's nice that we can prevent this issue by cutting the filament, but it's very inconvenient as we can'y access the tip at the end of the spool until it very close to being empty. We've had to pause a lot of prints before we leave for the day as the material would run out at some point during the night.
Does anybody have another remedy to this, or is Ultimaker planning on doing something to prevent the end of roll from jamming?
