When printing a model I pause the print at around 80 % complete to insert a new spool of filament since I'm at the end of my last spool of Polymaker PETG. I used Slic3r Prusa edition to slice the model but I didn't put in for the print to change filament. Then when I did my pause to fix the new filament into the gear on the extruder so it continues to print and feed into the hot end. After fixing the new spool into the extruder and resuming the print it starts too far above the actual part not allowing it to actually continuing the print. Is there anything that I have to change in the G-code that will then resolve this or is this just a slicer error or a print error with the G-code that comes stock with the Ender 3. Or do I have to plug the printer into my computer to then fix the error in the G-code?
