Trouble Printing ESD Filament on XL Nextruder.
I've ran into this before and now it happened again over the weekend. We have been using 3D ExTech PETG ESD filament for years with our MK3 printers and it prints relatively well with our new XL machine. The issues I'm having is that every few spools of it, the nozzle will become plugged way up high in the tube and the print will continue to print while not extruding material. The only fix I've found is to replace the nozzle and start prtinting again.
Does anyone know what is happening or how I can prevent this from occuring? It doesn't make any sense that a nozzle will print for several hours then all of a sudden just plug up? The filament feeder gears will push until it strips the sides of where it can't push anymore. Something causes a blockage inside the brass tube.
Any help would be great. All I got from Prusa is that the ESD-Safe Filament | 3D Printing | 3DXTech material isn't approved for the machine. Not sure why.
