I got a blob of around 5 x 8 cm out of PETG! Setting extruder temp to PETG or even a little higher. I did all with an older soldering iron. Simply (but carefully!) go with the point into the blob and take it slowly off. With a copper 'toothbrush' cleaned the extruder and nozzle more times. After mostly all was down I started first an first layer test (Prusa ...

I removed the mat from the bed and popped the print off

I had this exact issue - PLA wasn't sticking to itself. It was intermittently being dragged around by the nozzle, and prints literally fell apart when removing them. The problem: bad filament. I bought a new roll and the printer worked fine afterward.

Advantage: It should print like regular PLA at PLA temperatures. Disadvantage: the embedded metal particles are abrasive and will widen your standard brass nozzle over time. The fix is to use a hardened steel nozzle, or for the extreme, there are options like ruby-tipped nozzles. Advantage: It should look "metallic" in a way that is more durable ...

Looking at the first image, it appears that the nozzle is a little too close to the glass build plate. You clearly see that the nozzle scrapes over the glass and filament is deposited on either side of the nozzle. Re-level the bed with a (thicker) piece of paper or with a feeler gauge. Alternatively, increase the height of the nozzle by re-defining the ...

I'd suggest running through basic maintenance. Check Is the nozzle clean/unblocked? If not clean it out Is the nozzle worn? If so, replace it Is the bowden tube okay in the hot end ? If not, replace, or at least shorten it. Are your e-steps calibrated correctly? ...etc Also consider whatever mods were made, and whether they help or not. There's a ...

The way to optimise retraction is to use this retraction optimisation tool, which tests various retraction distances and speeds. Remember to perform this calibration AFTER you set pressure or linear advance, which has a higher priority. You will be able to pick the settings which work the best for that filament brand and type. You will have to do it again ...

Something strange happened to me (Ender 3 with CR Touch), changed my firmware and stringing happened. I was slicing with Cura and went through three days of breaking my head. You know how I fixed it? Simple, I looked for a pre-made retraction temp. And guess what? It was the slicer all along. I changed to Simplify3D and all of my stringing disappeared. I can'...

If the print bed is contaminated with oil or fat, print bed adhesion may be too low. Cleaning with alcohol might help.

After some trial and error, the answer seemed to simply be to "add heat." I bumped both the heat of the plate by 15 °C, and the extruder by 20 °C. I also increased the size of the first layer to between 0.3 mm and 0.4 mm and it's looking much better.

The extrusions look great to me, it just appears to me the nozzle is starting too far from the bed. If you go in to your slicer and subtract 0.1 to 0.3 mm or so from the Z-offset that might fix your issues. Or follow the supplied directions on how to tram (level) your bed as this tends to include setting the starting Zgap. If you did set the gap to your ...
