PETG Leaves Blobs While Printing...



  • ...with a CR-10 and Cura 4.8. Seems to print great but every once in a while, say 2 or 3 times during a 3 hour print, there will be this blob of material that appears randomly. Sometimes off the part and sometimes right in the middle creating all sorts of havoc. Any suggestions very welcome. Thank you



  • @lhawes You might have some PETG on your hotend where its not supposed to be and it heats and falls off. See if you have some filament between the heatsink and block or some around where the nozzle screws in - then you have a leak inside the hotend and it will get worse. You probably will either have to do a real good cleaning and reassembly job or replace it
