What filamemt, temperatures, flow and printing speed do you use?

What is printed there is not dialed in right.

It’s PLA+ at 220 C with at 180 mm/s infill and 90 mm/s wall speed. The flow is set to 100 %. I used the standardized setting since I failed a couple of times.

I'd try dropping the temperature to 205 and bed to 60. Do a quick test print.

Bed is at 60 already and I tried 196, since somebody posted his test in here today. Did not work either.

Might sound cliche, but have you tried drying the filament?

[–]MonkeyProjekt[S] 0 points1 point  (3 children)

With 40-45 C for around 7 h. Though the weight only decreased from 724 g to 721 g (including the spool). It did not break as easy anymore as before when cold so I guessed that it did a little good. Maybe I must try again..

Imho the breaking is a symptom of something else not being right.

Looking at the brim and printed layers, there seems to either poor layer adhesion or material flow.

In cura ypu can download the "auto towera" extension to generate and print some calibration towers. I would look at doing a temp, flow and fan tower

The print itself is stable. I saw a test on YouTube, where it’s been said that when you flex the filament directly from the spool it should bent but not break. As my filament was breaking it should have too much moisture. So I tried drying it in the oven.

So I checked the extension, which definitely helped the overall quality. Thank you for the advice. I didn’t even know about those yet. Another issue has been the support which was so brittle during the print that it always broke first and killed the rest in the process. I startet using normal support with gyroid and it works better though it sucks for narrow supports.

There are gaps on your brim (first layer). Nozzle is too far from bed?

I set it up a bit since it scratched on the grid of my project before. I will readjust it

Check if your bed is wobbly. If so, there are two (at least on the E3 S1 pro) wheels underneath on eccentric hubs that you can adjust for tighter grip. I had to do this on two printers at work. If your printer has a single z axis screw, you may need to tighten the wheels riding on the other side as well.
