Hey there
I was looking to buy H2D for my special project which requires printing two TPUs at the same time, 95a and 85a. I know that you can’t feed 90a and 85a in to the left nozzle, but nowhere i coudn’t find if you can feed 95a to the left? Did somebody already tried it?
Unfortunately it wont let you, throws an error. Same thing happens when you try to print with PPA/PPS in the right nozzle.
Thanks mate, that’s bummer
Ya I was hoping to have dual color 95A prints, this sucks for sure.
Is there something inherently different about the TPU profile where you cannot just create your own filament type and just match all the settings?
Yes should be theoretically possible. But I wonder why the limitation to right nozzle, maybe will cause an extruder jam as its not optimal for TPU. Will test this out eventually when I have some time.
BTW, i tried to create a fake TPU profile by changing filament type, but in Bambu Studio it’s greyed out, is there any other way than creating a new filament and copying all the tpu setting?
Why can’t I just change type like in Orca…
You can always cheat…
Create a PETG or ABS profile instead and fill the TPU values in it.
Won’t give you the benefits of more or less tuned defaults but means you print (or try to) whatever you like.
After all - the filament profile mainly deals with temps and cooling settings…
Add a good k-factor calibration and all should be good.
BUT > This won’t mean I can recommend doing this as clearly Bambu has reasons for these limitations.
So if something gets messed or worse there is no chance Bambu gives you a warranty claim…
Big question is WHY there is these limits …
Is the filament transport, issues with the heat removal, mechanical or sensor issues, …
Could be just to make us suffer but without knowing all ‘workarounds’ mean you take a severe risk…
I think when the left hot end gets lowered there is a gap between the extruder and the hot end entry point, that why soft filament like TPU wont work, that is my best guess.
