So I have a bambulab A1 and recently wanted to print something with TPU. The issue I have however is that the extrusion is just hella inconsistent. I get a coupel seconds of normal extrusion and then a couple seconds of pretty much none. The first layer was only half filled when I checked and I want to know if you guys have any suggestions.
I used the base preset for generic TPU.
Gotta dial in those settings, I had lots of issues with tpu at first. I found my specific issue was with my retraction amount and getting clogs. Some.brands have profile for their fillaments on their websites that I’ve found good in the past
I found the profiles but they only have them for different bambulab printers. I assume I can use those though?
I would assume so, worst that can happen is a failed print
turn off dynamic flow calibration, and print slower. Don’t use AMS, you have to use the external spool holder.
I never used dynamic flow calibration and don’t have an AMS. Should I just reduce the default preset speed then?
Maybe try with these settings (found elsewhere) : imgur.com/a/vGV9DV0
It seems like it’s the default TPU settings with these tweaks :
Thanks. I’ll try this if the manufacturer preset turns out to not work

Is your filament dry? With TPU, it’s the first time that I saw a drastic difference of print quality. I dry my TPU for 3 hours at 45°C each time before printing.

I dried it for 8 hours before printing

After that the next step is usually to do a test print where you increase temperatures until you’re at the maximum range for the filament.
Basically you’re searching for the sweet spot (heat is a major variable because it also affects flow).
