TPU with no stringing, how?
I run a small print shop and I've owned close to 25 printers over the last few years. Various brands and models.
I just picked up a new Mini a few days ago. I'm not new to Prusa or Prusaslicer though, as I have a MK3/MMU setup that's been a real workhorse.
I specialize in printing TPU, and that's where I'm having trouble with this Mini. For the life of me, I can't figure out how to get a clean print. Its either solid, but littered with strings, or underextruded and falling apart. I primarily print Sainsmart TPU, so of course I tried the Prusaslicer-provided profile, but it print waaay too hot and covers the print in strings. I tried adapting my MK3 TPU profile to the Mini, but that turned out no better.
Is it possible to get a clean TPU print with the Mini?
From doing a bit of reading here in the forum (I had previously just searched google) it sounds like I need to order the Bondtech upgrade.
I thought I had z-lift disabled, by unchecking it in the filament settings. Then it occurred to me that filament overrides were exactly that, they override the default printer settings. So I checked z-lift and set it to zero. Barely any stringing!
Are you willing to share the TPU settings you are using for SainSmart TPU
Thanks for the advice! I read it and it makes sense.
