This is solved.
in c:\Program Files\Bambu Studio\resources\printers\filaments_blacklist.json
Change the action to “warning” for all TPU filaments. The AMS check will then pop up a WARNING that TPU isn’t recommended, but you can click ok, and it will allow you to proceed. Here’s my filaments_blacklist.json file as edited
It should correctly say: You can, we’re just putting in hurdles so that you can do what we even confirm is possible… and I don’t have to understand that. My solution, TPU on the M5 and that’s it - Fully satisfied with this solution and bye bye Bambulab for TPU. It’s very easy and extremely simple - fired on TPU and done.
Even if the link has been shared here several times, first thurh the_Raz. This describes the TPU compatibility of the AMS…:
And when you want to load TPU into the AMS the printer still says no.
Flashfroge, Checking for updates: On or Off (on the printer itself)
New update avalable, you like to install? (on the printer itself)
By Flashfroge I do not have to install an app to check or install any Updates anywere like by Bambulab - well everyone can do it as ever he wan`t. In my case Bambulab just getting fierd for TPU and I just moving forward to the next printer.
I`m not the electrical drill service machanic for every manufacturer. And those who want to do that, thas also absolutely fine - no problem at all I’m also not looking for a hobby that I can tinker with to pass the time…
And I certainly won’t use a advertising billboard for Makerworld as a slicer. Again, those who want to do that, thas also absolutely fine - no problem at all
You see he has incorporated “makerworld billboard” in his training data from that other post. Also how could a human mistype Flashforge as Flashfroge EVERY TIME.
You’re not going to “screw up the AMS”… yes, it may jam, but its simple enough to clear the jam… cut the filament at the spool, unplug the bowden tube from the back of the AMS, and pull the filament out through the back… simple and easy to clear… I regularly pring 98A TPU with my AMS, and it jams about 3 or 4 times, and this is how I clear it every single time… yes, its a bit of a nuisance, but if you want to do multi-material prints with TPU, there aren’t really any better options.
I have an idea. Maybe have a grabber on the pyre, and starts at output of Ams. It somehow grabs onto the filament, and moves along the ptfe with the filament.
The problem is the ptfe tube. On my other printers, to print TPU, the instructions state to run it directly to the hot end and to NOT put it through the bowden tube also known as a ptfe tube.
Has anyone considered using Capricorn instead of Bowden? It might work (at least for a while). Worth a try.
“Capricorn” is an overpriced brand of PTFE (Teflon) tubing.
A “Bowden cable” is the name of the mechanism: it’s like your bicycle brake or gear-shift cables where you have a fixed outer housing (the “Bowden tube”) and a moving inner cable that transmits force.
3D printers use the Bowden cable concept, though not to transfer force, but simply to route the filament to a destination. The housing is Teflon because it has low friction compared with similar plastics.
I have used Overture high speed TPU in the AMS a lot. I have not had an issue. Simply create a PETG profile and port in all of your TPU specific settings. It works like a dream. Ive got a print going right now that is TPU and PLA combined together so I can have print in place flexible elements. So far it’s been churning through filament changes without breaking a sweat.
I also recommend printing any TPU at a lower temp than suggested. 210 C has seemed to be perfect and it reduces the amount of stringing and enhances the clarity of clear TPU greatly.
Not exactly. You seem to miss the point of why people use the Capricorn tubing. The feature of the Capricorn that is desirable to TPU printing is the smaller inner diameter that better supports the TPU and prevents it from buckling or getting jammed up in the tubing.
From the Capricorn website; 1.9mm ± 0.05mm Inner Diameter A tighter inner diameter tolerance than traditional tubing reduces the “wiggle room,” or buckling, inside the tube, allowing you to print flexible filaments even on the longest Bowden systems.
