Problem encountered while printing with PETG, HELP needed!
Hi everyone, I have a quick question toward my PRUSA i3 Mk3. So, I was printing with PETG earlier, and the first layer printing was as shown in the picture attached. I was thinking the nozzle is too close to the sheet, so I ran a 1st layer calibration, but the result does not look fairly good though. Then, when I took a look of the nozzle, there was little filament segments extruded from the nozzle even before the printing starts. As I kept the nozzle temp high (250), there was stringy filament kept coming out of the nozzle. After I unload it, it looks like what the picture shows. I am wondering what's going on? Is the nozzle clogged? How should I fix it? Please help me, thanks!
