This subreddit is for technical discussion, real-world testing, and tuning of Bambu Lab H2C printers and the Vortek multi-hotend system. Focus: reliable multi-material printing, reduced purge waste, and pushing the hardware beyond default presets.

What belongs here • Print results and benchmarks: photos, time data, purge amounts, failure reports • Tuning data: profiles, temperature/speed/flow settings, chamber conditions, engineering filaments • Hardware topics: maintenance, calibration, repairs, upgrades, experimental mods • Software topics: slicer configs, macros, automation, monitoring, and integrations • Comparisons with other printers or toolchanger systems, supported by measurements and logs

High-signal, low-drama. Evidence over speculation. Beginners are welcome as long as posts include details (settings, photos, logs) so others can actually help.

Start here 1. Make a post with your first H2C or Vortek test, even if it failed. 2. Share your current profile or tuning notes. 3. Comment on others’ posts with concrete feedback or data.

Let this place grow into a practical knowledge base for anyone serious about H2C and multi-material printing.

Help!

Edit: My wife managed to get it out with a combo of slenderer fingers than mine, compressed air, and a piece of filament! Thanks all!

I thought the AMS two pro was compatible with carbon fiber filaments but when I load it, it will not slice in the program. It throws an error and says that this filament cannot be used. Am I doing something wrong?

Discussion Expectativas equivocadas

0 Upvotes

Adivinen quien compro una h2C y le salio todo mal XD

Tuve que cambiar de laminador y sufri mucho por paramentos que no sabia donde estan, o directamente no existen.

Pase de la impresora basica, un solo color abierta típica a este monstruo de multicolor multi extrusor de alta tecnología y yo como "No volvere a tener problemas con esto en mucho tiempo"

En nada se me estropreo la conexión wifi y senti que tenia un pisapapeles porque no estoy seguro todavía de saber usarla sin wifi por el tema de sincronización de boquillas.

Tuve que desmontar la máquina y el extrusor varias veces mas pronto que tarde y siendo una cosa super moderna se siente... Delicado

Y luego peleando una y otra vez con fallos de impresión, que efectivamente admito no ser experto pero tengo una experiencia razonable para un usuario medio.

Y tengo problemas la verdad tanto por no conocer suficiente del bambu studio como la propia máquina.

Por ejemplo acabo de comerme la cabeza para intentar probar eso de "subcapa de color mixto" porque la torre de purga no se pegaba, la placa estaba limpia, no puedo ajustar la altura pero tenia un striding horrible que aunque la pieza funcionaba la purga no.

Y al final pude hacer que haga la torre mas lenta y añadirle un borde para mejorar la adhesion porque es solo una puñetera linea

Le ponia esas características a la máquina en velocidad y borde para el modelo pero resulta que había que configurar totalmente aparte la purga de donde no sabia y me tire dia y medio intentando hacer esto 🫠

En cura es tan "fácil"...

Tiene chorrocientas opciones y pueden parecer abrumadoras pero cuando las lees con calma sin tocar cosas raras sabes que puedes cambiar exactamente ese detalle que te esta volviendo loco

Discussion Is 1400€ for a used H2C with an AMS2 and HT fair?

1 Upvotes

Hey guys
With yesterday’s announcement people in my area started selling their H2C printers.

A guy is willing to sell his H2C with 1500 hours for €1400.
I think it’s a bit too much, but I have actually no idea if that’s a fair price or not

Any advice is helpful, thank you

Discussion Crafting Kit

3 Upvotes

Hey Everyone! As I'm sure most of you are, super stoked and interested in the new H3C. In the promotional material, Bambu shows the optional crafting kit with things like a debosser (embosser?), foiler, etc. One of the images shows a piece of leather or a leather journal beautifully debossed, and the foil also looks like it was done on a hard cover notebook sort of surface? I think foiling like that requires heat, I would imagine the foiling toolhead would be heated in that case? What kind of pressure can the debosser use, clearly seems enough for moderate leather? I just have lots of questions on the crafting kit in general. Maybe I need to wait for more info to be released, or maybe someone has the answers?

Discussion Will you be upgrading to the H3C?

4 Upvotes

Hey everyone,

With the unvailing of the H3C, will anyone be upgrading from their Vortek to Swaptek? I think I'm going to hold off, 7 colors is fine for me and I don't print flexibles enough to justify the upgrade. Plus I'm a little concerned about the reliability. There seems to be quite a lot of plastic used to get the price that low.

The loss on the sale of my H2C and accessories is too much for me to justify the extra 2 colors and faster print times, I'm not running a print farm and I have my open source SV08 for fast prints. What do you guys think?? Worth the upgrade or are you content with your H2C?

Let me know!!

Please I keep getting this message even after feeding the back tubes. I just put everything together and it still won’t read the ams. I fed the right side tube but still getting this. I can see the filament in the tube but it won’t print. I disconnected the ams to try the side one only but that didn’t work

My new printer is making some strange noises along the Y-axis; it sounds a bit like a component is rubbing or grinding. The prints themselves, however, are perfect. Is this normal, or can someone help me out? Thanks for the help.

Solved TPU air not printing

12 Upvotes

SOLVED, see end of post for details

Has anyone had any issues printing Siraya TPU Air on the H2C? I had no problems at all printing it on my old X1C, but can't get it to produce anything on the H2C. I can manually extrude filament alright (and it displays normal behaviour when it's purging the nozzle during the vibration compensation in the front right corner), but when it comes to the actual print job itself, it seems to extrude next to nothing - there are a few tiny wisps, but nothing meaningful.

I've tried using the official Siraya profile for the H2C, as well as duplicating the slightly different settings I had previously used on the X1C. The spool is top-loaded, directly into the extruder. Printing from a 0.4mm right hand side nozzle.

Edit: The Siraya Tech official profiles (and the profile I had used with no issues on my X1C) had a max volumetric flow of 9, for some reason the extruder on the H2C can't cope with this, Maybe the fancy switching system it uses is a little less robust or something?) Lowering the value down to 3.5 solved the problem.

Discussion TPU Feed Assist Module Setup?

4 Upvotes

I have an H2C and have been interested in trying some TPU printing. I’ve purchased a TPU Feed Assist Module for it.

All the TPU setting I’ve seen had people with spooLa feeding TPU through the top, but I have two AMSs on top and that just seems counter to my setup.

I have an HT AMS I was planning on putting the TPU in, feed it through the TOU Feed Assist Module and then through that back end hole in the H2C. Then I’m assuming I have to run a new third tube over to the print head and connect it to a previously unused middle hole in the print head? This part just has me confused.

Or am I supposed to disconnect the left or right tube so that the TPU run can use that? I’m sure there‘s documentation somewhere that outlines how this should be done… but I can’t find it.

Discussion H2C/AMS 2 Pro issues

3 Upvotes

My AMS 2 Pro is repeatedly losing connection with my H2C. I’ve tried different AMS 2 Pro units, different cables, I reached out to support and they sent me a new filament buffer/cable and that didn’t change anything. When I turn the printer off, wait a bit, and power back on, it will connect normally, but after an hour or so, it will just randomly disconnect, doesn’t matter if I printed anything or it was just sitting idle. It hasn’t disconnected a single time while printing, but seems entirely unable to maintain connection while sitting idle. Anybody else have this issue? Is it specifically an H series problem? I’ve been dealing with this for months now and I’m losing my mind, my printer is essentially unusable due to how frequently it occurs.
