For Tpu you need the shortest way from spool to extruder. The more tube you have, the more screwed. You can print Tpu just fine using the spool holder, although, I rather have the spool on top of the printer with just a short tube going into the print head directly in the extruder, much better
I did the overhead ACE mount. Printed out a couple lid-hold-openers Spool sitting in the ace. filament runs out the open lid directly into the print head. works great. you'd probably need to set up some dangling overhead pulley system to print TPU if you didnt do the overhead ACE upgrade
I'm planning to put the ACE above the printer anyway and ever wondered if it is really not possible to find a way to mix print TPU and other materials. For example to print sealing directly within the model. When you use the ACE like you described, will the TPU filament be rewinded as much as needed to let the ace switch to another material if the TPU was printed in some layers? If, then this would be a great and simple solution.
@stefankauerauf4282 I disconnect the multi material hub and drop the single stand off tpu directly in. I'm sure they'll figure out how to do it sooner or later 🤷
I'm using the spool to print with TPU, it works well, although with some details. Since this is my first printer and I'm new to this, I didn't set the speed correctly and apparently, TPU filaments need a slower speed than other filaments. I set the bed to 50°C and the extruder to 215°C. I did this halfway through the print and it made a big difference, before that, the print base had lifted at the edges.
I have The same problem with “support for PLA/PETG from bambulab, but sometimes works and sometimes doesn’t. I didn’t do anything, just ok resume printing, still no idea to solve the problem
Ohh really, I guess it is hard for these multi color systems to print with soft filaments then. First time using one so I don't have much experience with it.
Yeah many people are getting that problem, I just keep sending it 2-3 times and if it does not work then I'll just restart the slicer or the 3d printer.
While the extruder is a direct drive extruder, the fact that the kobra 3 has really long bowden tubes it effectively acts as a bowden extruder. So super flexible filaments don't work well. I don't know if these exist, but is there any kind of filament that has tpu with a PVA core? If so, you could use the more rigid PVA and dissolve it with water afterwards. It would leave some gaps though so i imagine that filament doesn't exist. Thinking outside the box: if the outer shell of tpu filament was coated with a rigid wax, maybe that would help it get through the Bowden tube.
I'm glad I subscribed already hahaha Very interesting troubleshooting video! Nice work. Also, I'm pretty sure you can print TPU without the ACE (since it doesn't support it). Please share your findings on that!
I have the Kobra 3 with ACE and it is amazing. I have a way more expensive Snapmaker that I only use for larger PETG / ABS jobs that need 1 color 1 material. Kobra 3 fast and amazing is a PLA God.

Yeah, I just want to try and see if it works on the Ace pro.

Yeah, if you print TPU directly to the printhead with no ACE then it works. Yes TPU needs to print slower.
Try it without the ACE Pro on the single spoolholder.
I'll try that, but what I was planning to do it using tpu with other types of filament.
@@Scratch3DPrinting I'm shure that it works 😉. I would maybe put a small piece of PTFE tubing in the print head and then the filament. Good luck.
@@rolfklein2688I failed.Kobra 3 noice me couldn’t link to colorxxxx(?),and stop print.
Could you share your machine or slicer setting?
I have The same problem with “support for PLA/PETG from bambulab, but sometimes works and sometimes doesn’t. I didn’t do anything, just ok resume printing, still no idea to solve the problem
Sometimes it's just not working properly.
The filament holder that came with the Kobra 3 is where the TPU goes. The Anycubic webpage says the Kobra 3 can print TPU but the ACE unit cannot.
ohh, thanks for the info.
just like the ams from bambu lab the ACE does not support filaments that are super soft like tpu it just gets wrapped.
Ohh really, I guess it is hard for these multi color systems to print with soft filaments then. First time using one so I don't have much experience with it.
@@Scratch3DPrinting yea it’s just such a long path for the filament to travel even if it gets past the buffer. great video though
I need help, I can't send it from the PC to anycubic kobra 3, it says sent successfully.
Yeah many people are getting that problem, I just keep sending it 2-3 times and if it does not work then I'll just restart the slicer or the 3d printer.
the correct procedure to remove blocked filament is described in the anycubic wiki....
Yeah, I just found that out too. Thanks.
While the extruder is a direct drive extruder, the fact that the kobra 3 has really long bowden tubes it effectively acts as a bowden extruder. So super flexible filaments don't work well.

Yes that is true, the ACE Pro is like a bowden tube setup. I'll take a look at that PVA core. Thanks.
I hope that Anycubic provide a solution when they reveal how to connect two ACEs with a hub!
Yeah me too, I just want more information on the kobra 3 combo.
GG man, is there a way of contacting you
Dude, they need to start paying you, you have already helped me fix 3 of my issues way faster than support.
I know! I think my channel is just too small for them to notice but we will get there together! Thanks.
I'm glad I subscribed already hahaha Very interesting troubleshooting video! Nice work.
Also, I'm pretty sure you can print TPU without the ACE (since it doesn't support it). Please share your findings on that!
Thanks for your support. Yeah I have try many time and it give me the same error. I'll try to print it without the ACE pro and see what happen.
Also looks like the issue was trying to push a rope up a firehose. 😆 maybe a tighter tube?
For sure, a tighter tube might do the trick. I'll do more testing.
Bearing setup looks the same as the Prusa MMU.
Oh really that's interesting to know. Thanks for the info.
Yea the bambu printers can’t do tpu in the ams not really sure of the reasons but a lot of them can’t do tpu
oh ok. I guess the filament is to soft to push in the back piece for the ACE pro to know that the filament is not tangle.
Nice been thinking about picking this one up
For me it is a good 3d printer combo.
I have the Kobra 3 with ACE and it is amazing. I have a way more expensive Snapmaker that I only use for larger PETG / ABS jobs that need 1 color 1 material.
Kobra 3 fast and amazing is a PLA God.
Always print TPU with external spool holder. ASA need to be printed in a enclosed printer like ABS with temps of at least 240/90. Good video anyway.
Ahh yes, but what if I wanted to to print tpu with multi color how would I do it with out using the ace pro.
@@Scratch3DPrinting add a print pause in slicer when you want to change color. I can’t print tpu in my AMS. Very hard to print multicolor with TPU
NO TPU. Have to do that seperately
Yeah, cant do multi filament printing on the ACE pro with TPU.
Hey Man, i was reading the Manual, and isn't supposed to print TPU from the ACE, but nice tutorial anyway for troubleshooting.
Ohh really. I forgot to read the manual for the ace pro, I guess that's why I couldn't get it to print. Thanks.
Thank You good video
Glad you enjoyed it
TPU could be print without ACE.
It seems like it could, I was trying to mix TPU with other filaments.
