Hi everyone, I hope someone can haelp me with a problem I've been having sin a change of filament in my printings. I use eSun PETG, prior settings 230 nozzle temp, 70 bed temp, 40mm/sec printing velocity and 100% fan speed, 0,1mm layer width. With this settings I was getting perfect prints, but a few days ago my filament run out and I change it to another, same brand, same material, same color. I started to print with the same file in my SDcard in the printer, same parameters as before and the infill started to show problems, also the first layers an walls. I've tried to modify the nozzle temperature, fan speed, printing speed, but no improvements. Any sugestion on this? Thanks in advance
