Can anyone help with TPU? To get good extrusion on walls, I need to set Extrusion multiplier (aka flow rate) to something ridiculous like 2 (200%), but of course that leads to severe overextrusion on tops and bottoms
1st photo: bottom walls are flow rate 1, middle is 1.3 and the nice top ones are 2. Second photo: bottom layers at FR 2, severe overextrusion and jammed extruder.
Speeds aren't it, I'm getting similar results with anything from 8mm to 30mm.
@stooovie You can also leave filament loop dangle, as this creates the lowest resistance and TPU isn't known to tangle. But you'll have to periodically tug it to create the new loop.
@stooovie If you aren't allergic to Discord, come to Lost in Tech one; way easier to troubleshoot there and more people that printed more than 2 TPU things (like I have). https://discord.gg/Yy64JqC3dZ
@stooovie oh. Did not see your other post where you wrote that. Just know that the only times I’ve printed with tpu 6h in a convection oven was not enough
@stooovie Well, my (very cheap no-name) roll had been sitting in the open for almost a year before I even started printing with it. I dried it a bit more after that and it was better, but not “perfect”.
There might be something else going on for you though.. Partial clog in nozzle?
@linus no, happens with a completely new nozzle. Also it was a completely new spool (I understand they can be wet out of the box). Maybe it's just shitty filament 😂😩
@stooovie Haha, might just be that 💩. I print almost exclusively in ABS/ASA so my TPU knowledge is a bit sparse. Havent even gotten through that first roll of mine…
Here's bottoms with Flow rate 1 (perfect IMHO), BUT walls with FR 1 look like this. Nozzle 0.6, widths 0.6 (single wall vase mode but any walls look like this)
