My tires take 5:15 on my A1 Mini. Slow produces quality TPU parts.
I use PVA glue on a smooth plate. Generic TPU filament profile in Orca Slicer. 0.2mm standard print profile.
I print a plate of 8 tires on my A1 with a .6 nozzle and 95a HF TPU in just shy of 11 hrs

Are you using the default TPU settings? My first plate failed miserably so I asked for help in a women’s group for dialing in the settings. I did the settings recommended to me and these tires have taken me almost 3 days per plate of 8 on an X1C, I am using Comgrow 95a 
they came out good and I have had no failed on any of the TPU since but it takes such a long time!
Default Bambu 95a HF settings. If I am printing with non HF filament the time goes up quite a bit. HF is around 4 times faster

Next time I’ll get 95a HF. Pretty sure Geetec isn’t HF

I have a geeetech profile I can share that works for me if you want. But yeah it isn’t HF.

I realize now that it did come off as bragging, and that is not at all how I meant it. My reason for that post was to prove that it can be done. Its not the TPU that is the problem, its how we are routing it to the printer that is the issue most of the time. It took me a while to learn that.
I didn’t take it as bragging… you offer a lot of wisdom on here and I have put a lot of it to use. You sharing the speed of your build lets me know that I can push these printers a bit harder than I have and still have excellent quality…
You still da Man!

Thank you! Dealing with others today has me making sure I am coming across the right way. Glad to hear I was!
Hopefully in another 2 weeks or less I’ll be able to post my review of the TPU Assist module on my X2D and get my first try with PLA supports for the TPU!
You guys really have me thinking about switching to the Dark Side aka Bambu labs. lol.
I like the dark side
It really makes things a lot easier. I started in the dark ages and 3D printing has never been my hobby. It’s just a tool to me for my other hobbies. So now I have a printer that works 99% of the time and requires so little tweaking or fiddling.

I have my sister to thank for pointing me to Bambu. She is a technology teacher in K-6. She has gone to numerous workshops and her town went 100% Bambu because they were tired of printers not working…lol. She loves them. I love my A1 and P2S. I am hearing a lot of good things about the U1. Love to see where this multi-head printing goes.
I saw the U1 but I don’t want to have to not use Bambu studio to manage multiple printers. X2D is on my wish list. Just waiting for mid June to see if Bambu does any sale

Loving the X2D so far, it’s amazing how fast it switches nozzles.

I just had to share. If you are having challenges with TPU, just hang in there. Everyone is here to help. This is Geeetech Transparent. What a nice first layer.

I need to get one of those plates for my next build if it’s like a rainbow request

Finally able to try out the TPU Feed Assist Module on the X2D with PLA supports. Assembling the module was a little tricky but all in all not bad. Had to print a part since there is no spool holder mount on the left side of the printer stock, but that was easy as well. The wiki talks about it needing “calibration” but the light never blinked and so far its just working.
Using the Bambu 95a TPU HF profile with some Sunlu High Speed 95a TPU The PLA supports printing every layer adds a little time and some waste in the prime tower, but if it comes out cleaner I am happy! Next time I might just do manual supports and just put them at the bottom instead of going all the way to the top. That top part you will never see once its installed anyways.

I’ve got the TPU assist setup on my H2D right now and its been incredible how consistent it is. Definitely picking up another for the other machines when its available again.
