I’m not sure why, but I’m having frequent issues with my Tz3.0 hot end and PETG filament. I was mostly printing PLA after I received mine and got the parts to fix it(heating element that ti came with was defective).
With PETG I’m getting frequent clogs in the nozzle and hot end with the 0.6mm nozzle. I tried a few different brands and colors of PETG and all of them have the same issue. As a sanity check, I put the Bambu 0.6mm how end back on my X1 and I’ve done close to 15 hours of PETG printing since then without a clog or any other issue.
I’m beginning to wonder if I received a defective unit considering all of the issues I had with it so far. However I don’t know exactly what would cause basically a metal pipe to be defective. I can’t find any issues with it when I look inside with a magnifying glass and light.
