Thank you for the video! The profile you mention on Printables eliminated my stringing problems so it's worth the extra print time. Have you tried to successfully print tpu 85A?

Bambu support tickets are the worst. My x1 I think was damaged in transport because it can’t print on parts of the plate without the belts failing. I’ve now been trying to talk to support for a return for two weeks. They are the least helpful people of all time and I’ve just been manually fixing it every way I can but it still can’t print fast and can’t print PAHT at all which is what I freakin bought it for

Do you consider that we need to modify the inside of the extruder to print with TPU? I am having a lot of problems printing big pieces with tpu with x1 carbon 😅

GAME CHANGING! I was having stringy mess issues with Bambu TPU 95A HF. I even dried it, no luck. Until I watched your video. Thank you!

Where is the 2nd part ?

I build one using sensor 1.2 and a ESP01 ... I cannot see (really) this working fine... every time is between 99 and 100% :( (some times I do not put water in plant for 2 weeks ... ) do you already test using ESP01 ?

I have been using the Bambu A95 HF TPU for several months and I have never needed to lower the speed of the stock TPU HF profile.. I only have to adjust the retraction.. Are you sure you have TPU HF? and Buy a PEI sheet..

I could not get the TPU to work at all for a couple of months. I did a firmware update about a week ago and tried again with the TPU and got a great result. I guess they may have fixed something.

Great video, gives me some new ideas! Thanks for sharing w us!

Please keep this gowing

Very nice video. Can't wait for the next chapters..... But MAJOR TIP/REQUEST: *Would it be possible to lower your screen resolution when recording please!* Even at 1080p playback it is extremely hard to follow along as the recorded resolution is much much too high (and thus texts, menus, etc way too small, even on 1080p playback). It is even completely impossible to see the GUIs and code on tablets with lower resolutions. PS: I wouldn't mind even more detailed/longer videos though 😉

Can't wait for the second part

Bought a Snapmaker J1 this week to print something like this and to speed up dual color prints.

Great video. Printing TPU is (was?) always a hassle, so you video helps to look at the right parameters. Thanks for sharing.

got my sub, thank you for all your hard work!

Hi, I just discovered your channel after researching tpu printing. I was really starting to despair, all my tests were horrible. I'm just starting a test with your profile and I don't know what to say, except thank you very much !!!! I'm only at the beginning of my printing but the rendering is simply incredible compared to before. You've earned a nice like and a new subscriber! Thanks again

Ah yes, the "wbdvfdaslfgaldgh" setting. I know exactly which one that is. If you're gonna present a video in English, make it ALL English ffs

Thanks for the video. I just used this method to print PETG-CF letters on top of TPU surface. I used the TPU setting to print the PETG-CF and had no issues. I am using a 0.6 mm nozzle which helps.

Thank you for sharing. I have been experiencing problems with my new X1C and I am going crazy. I can find good settings for it. Could you please share your settings for PETG? Thank you.

Dude this seems to have been the solution to my TPU issues! So happy the print is finally looking as it should. Thanks for the awesome content.

Thanks a lot, this really helped me out. Making a very simple gasket 0.6mm thickness, from 26 min to just 18 min blowed my mind, with slower settings... ?? Cheers from Sweden

can I put PETG in ams and tpu on the external spool holder, and print it without touching printer?

Also waiting for whenever you are ready...

Nice video , also i am waitng next part

Somehow bambu lab printers bring back old hearsay about tpu… It does not need to be printed slow or with slow volumetric values. Bambu lab printers can print tpu fast but you need to lower the tension on the extruder which needs to be modded for it to be easy. I printed well over 100kg tpu and print it at 25mm3/s. You also need to have as little friction as you can for the extruder when pulling the filament. Also tpu likes to build up an over pressure in the nozzle so one needs to usually run really high values to compensate that. I have not bothered with tpu on the bambu printer cause I have bigger printers printing tpu faster. So can’t say for sure how fast the bambu printer can print tpu. All I’m saying is that I know it should be able to do it way faster.

Sorry guys, I'm unfortunately behind schedule with the second part of the video. I should be finished by Thursday next week.

I also had to figure this out by myself. Though, im still able to print TPU on 150$ Ender 3 with 10$ direct drive upgrade ~7mm3/s with far better quality than in Bambu with 2.5mm3/s. That printer is just not for TPU.

If you get hard enough TPU you can just use it in an AMS

Seems like you had used the TPU HF profile for normal TPU? Because in Bambu Studio the normal profile is also set up to less than 4mm^3/s for the standard TPU 95A and the 12mm^3/s are for the modified TPU HF. I had 0 problems with the TPU HF I had recently gotten and the default profile.

Thanks for a great video, it is helping me a so much in finding out which hardware to use at home for my set up (indoor and outdoor plants). I look very much forward to your follow-up video. I especially like that you are comparing multiple boards and sensros, and also appreciate the structure of the video (distinct chapters and also sharing the various requirements in the way that you do). Thank you for all the effort you put into this!

I wish the TPU would work in AMS :(

That's interesting, thanks for sharing this 👍 I don't use ASA but have a lot of ABS that I use when i need better heat resistance or electrical insulation, having used a bit of TPU (with good results) I'll give a try to mix the two!

Now you just need to print 3 more! Do they work for damping vibration?

Why is there even a purge tower here? I do this on my Ender 3 all the time. Just setup the model, add a pause at the layer you want to switch, slice with one filament, save the gcode, slice with the other filament, then splice the two gcode files together where the pause is. Doesn't even matter if they are the same temperature range, just add temperature gcode at the splice.

@Willis3DDruck [German] created a video where he combined ABS with TPU: th-cam.com/video/5soAu6cinP0/w-d-xo.html

I'm using a P1 and a combination that works pretty well for me is Sunlu TPU with the Generic TPU profile - combined with the drying that you've already mentioned in your video. In general I can say that the Sunlu / Jayo brand works pretty well with the general profiles

If you change the seam to random, you won't get the seam in a vertical line...

why are you wearing gloves ? :)

Danke für die Erklärung. Habe gerade genau das gleich Probleme. Ich werde das mal testen.

I can do this exact same thing on my CR10s without all the software headaches by merely adding a layer interrupt script. Seems like more money to do more steps which in turn wastes filament by creating a purge tower which is wholly unnecessary.

Enjoyed the video. I actually started out with quite good TPU prints, and wondered why everyone else had issues. But I had downloaded a profile and was using that. It was fairly fast, with 140mm/s outer walls and I was using the 12mm/s3 profile. However, I had also almost immediately installed the aftermarket high flow head from aliexpress. At some point, I took that off, and my TPU prints started under extruding and failing. In search of a middle ground, I did the flow rate testing and played with higher temps. I found I could do a flow rate of 8mm/s3 if I upped the temp to 260. The head can still flow much more than that, but I believe the issue with TPU becomes cooling on overhangs. You probably have higher expectations than me, but I think you could go just a little higher on your speeds and still get good results. I've been so impressed that I can print TPU at the speeds my old bed slinger would print PLA. And the time is soo much shorter because of the travel speed.

FireBeetle 2 ESP32 C6 on DFRobot seems to be advertised as a board that has a "Solar Power Manager" and battery management - their marketing photo shows it connected to a soil moisture sensor, LiPo battery and Solar Panel. I stumbled on it randomly because I was searching for the most power efficient boards and FireBeetle seems to be one of the best "sleepers".

Hello. Great video. A tips for you, insted of hitting resume and pause, you kan hit close and use the meny as you want. You can even lift the table up and down ass you wish. When finished, go to homescreen and press resume. It will go back to correct tablehight by it self. Works great, espesially when embedding nuts and bolts in to prints 🙂

Any reason of why you are not using the AMS? Shouldn't it be even easier with it? Or it this just to make a compatible video for other printers?

So basically do what people have been doing for years. Pause and change filaments manually.

Please choose a different music for the background. Good lord is that annoying.

You don't need to press "pause" again on the filament switch. Just press "close" and the printer will wait for for next instruction (filament change, continue).

Good video. If the music wasn't there it would be better. That is annoying noise- not music.

This topic is super interesting! We have already carried out tensile tests to test the adhesion of different material combinations. Take a look and see for yourself -> th-cam.com/video/QI6OEWRrKq4/w-d-xo.html
