Ender 3 Pro printing with PETG
I am still new to 3D printing, but have most of the basics figured out, and have had fun printing with PLA. I have an Ender 3 Pro with CR Touch, a glass bed, and upgraded Capricorn filament tube. I bought my first spool of PETG from Amazon (Overture). No default settings on Cura so I poked around until I figured out how to customize the material. Spool says 230-250oC nozzle and 80-90oC bed. I split the difference and used 240oC nozzle and 85oC bed. The generic PETG was 70oC bed and 215oC nozzle which looked liked it wouldn’t work for this material. Some videos I saw said 240oC minimum for PETG.
I uploaded a picture of the first layer. The outline printed ‘fatter’ than I would see with my PLA prints, and the first layer of a solid wedge shape was fraying off the bed. Bed adherence doesn’t seem to be the problem, but almost that it’s pushing too much material through the nozzle. I haven’t figured out playing with feed rates of material. Before I tinker too much on my own, I thought I would ask for help… Any advice appreciated!
