Thank you for sharing. i have recently purchased a U30 and no problems with PLA, i would like upgrade for TPU with your model.
where should we put the additional PTFE tube ?

Thank you

It depends on your coupler. If it is wide enough so that ptfe goes all the way through coupler it should go just to the extruder gear.
If coupler is smaller (original) you have to cut and put additional piece of ptfe inside the part.

I've recently purchase tpu but couldn't extrude anything properly with my alfiwise u30. Could you help me with the settings ? Also if you have tips to make it work it would be great. And thank you for this post

Hi. It doesnt really need any specific settings. The most important is to print slow and use tpu with more hardness. very flexible marerials are hard to print.

Must have fot TPU, easy install - no more problems :)
