Each time printing TPU on the x1C it prompts me to cold pull before doing so.
It would be great if Bambu could implement the walk-though sequence for cold pulls in the tools menu, like the H2D does. Any reason this hasn’t been implemented already?
Thanks :o)
The short answer to the question $$$$$.Why do you have to do a cold pull? I use TPU, no issues. Can you print with other filaments with no cold pull?
I don’t usually do a cold pull before printing TPU and I haven’t had any problems yet… 
I completely agree with this!
It says to use the printer menu to do the cold pull but it’s not there… it looks like cheap not to have such a simple thing implemented.
Unfortunately companies usually do not add features to a product that is marked EOL.
End of line, perhaps, but there are a large number of existing Bambu customers who have X1C’s as well as other Bambu printers. It’s such a simple thing to implement, for the benefit of many thousands of users.
Because TPU is softer and more likely to clog, if the nozzle has residues of other filaments still in the nozzle, particularly filaments with a higher melting temperature.
I agree with that, I still have my X1c!
I have switched between ABS and TPU with no issues.
Congratulations. I guess Bambu put that cold pull warning there for no reason. 
I have been using “TPU for AMS”, switching from PLA with no issues. The soft TPU is another story.
Personally I don’t bother with the TPU for AMS. It’s not a true TPU, in terms of it’s properties or usefulness.
It’s one of my favorites for strong parts like castors, gears, giant lids, rollers etc. I use from 5 walls to “all walls” on everything. Wish they’d produce some dark grays and even harder variants.
Never cold pulled!
I’m in the process of trying to get one of Bambu’s TPU Feed Assist Modules (now expected 5/21/26) to use along with my AMS HT so I can use Bambu’s TPU 95A Hf Filament, the real flexable material. The TPU for AMS is better than nothing, but not real soft.
