Am i to stupid to Print PETG?!!
Sadly, there isn't a German CORE ONE L forum, so I will try my best in English.
First of all, I’m not new to 3D printing. My MK3S worked so amazingly well that I might be a bit spoiled by it; I never had issues with PLA or PETG on that machine.
I had a rough start with the Core One L because I didn’t mount the 0.6mm nozzle perfectly, which caused a minor crash. Luckily, no permanent damage was done. After that, I printed a few Benchys and Cali-Flowers in PLA, and everything was fine and accurate.
The printer is supposed to run daily for parts and jigs in our woodshop. I bought the Core One specifically because I want to design in Fusion and print parts quickly. However, it seems my Core One isn't printing as well out of the box as I expected. I admit I’m a little frustrated; I don’t want to spend time "tinkering"—I want to work and provide my employees with the parts they need just-in-time.
After some issues with large ASA parts (which were mostly geometry-related), my PETG prints are now failing as well. I’m using Prusament PETG right out of the box to print feet for a steel table. Here is what I’ve tried:
1st Attempt: 0.6mm nozzle, 0.32mm Structural profile (255/85°C), 4 perimeters, 6 bottom/4 top layers, 20% infill. Result: Huge layer shift at the top. No Foto
2nd Attempt: 0.6mm nozzle, 0.32mm Balanced profile (255/85°C), 2 perimeters, 4 bottom/5 top layers, 100% infill. Result: Nope
3rd Attempt: 0.6mm nozzle, 0.4mm Structural profile (265/85°C), 2 perimeters, 100% infill, reduced volumetric flow (10). Result: Also poor, canceled
4th Attempt: 0.6mm nozzle, 0.3mm Structural profile (265/85°C), 2 perimeters, 100% infill, reduced volumetric flow (10). Nope
5th Attempt: 0.6mm nozzle, 0.3mm Structural profile (265/85°C), 9 perimeters, 15% infill, reduced volumetric flow (10). Ok, but not
6th Attempt: (Tried standard parameters with a 0.4mm nozzle to rule out user error): 0.2mm Structural profile (255/85°C), 2 perimeters, 15% infill. Result: Severe layer shifting, canceled
Should I contact support directly? I invested a lot of money into a Prusa specifically because I need a reliable workhorse for my business. Any help would be appreciated.
PS: Actually it prints a perfect PLA print....
