Hi , I have a cr-10 max and have an issue about it. I sit all the sittings for printing 3 days ago and left it for 10 hours. When i came back i found that the filament comes loose in so much quantity down the nozzle which formed a hard circle shape which stopped the process. Now i tried to remove this from the nozzle but it is too hard and i do not want to affect the head of the printer. so any solutions please?
