New 5 Pro underextruding



  • I have a new 5 Pro that has decided to grossly underextrude. Prints now come out as strings woven together. Have replaced nozzle, cleared tube and I can freely push filament thru a hot nozzle. Extruder calibration pushes 47mm of filament instead of 100mm. Filament is 1.75 white PLA. Have adjusted tension spring on extruder with no change. Any ideas?



  • @modeler1363 there is a setting that you can choose what size filament your using on the LCD. My was set to 1.75 and it caused major under extrusion. Turn this off and try again, this fixed my issue.
