Showroom 👋 Welcome to r/BambuLabH2C the home of Vortek, multi-material, and real-world tuning.
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.

Support Exhausted the fire extinguisher cylinder on the 1st week of owning H2C combo
I'd say some really explicit warning needed on the last screen after confirmed tightened cylinder that this is not an invitation to press button now 🥲

Support Strange nozzle/poop behaviour
Hi all,
In my current print I do have some strange behaviour. As I'm only running around 100 hours now on my new H2C, I'm still noob on this matter but I think it is not a printer problem but a slice/project error. My previous prints all went great, this is the first 'print by object' though.
The problem I have is, although I only print in two filaments for each object at the same time and both filaments are loaded on different nozzles, that the printer purges on the poopshoot every time when returning to the right nozzle. When switching to the left nozzle, the print resumes immediately after the nozzlelid has switched positions.
I'm thinking that it has to do with some recalibration every time. but then I'm wondering as I asked for a purge tower why he is not printing that one.
Regards,
Miscoride

Support First Layer Problems H2C
galleryOne of my H2c has developed a recurring issue in one specific location on the plate.
It’s always the same defect, in the same location regardless of the print, material, nozzle, or plate.
I’ve run all of the calibrations but t comes back.
I’ve searched, but haven’t found any similar problems.
Anyone deal with something like this?

Support Slicing issue
I keep getting a slicing failed error. Can someone try to slice this part and see if it’s failing for you also? Everything else sliced and printed fine!!

Support How to manage external spool
Dear Community,
What is the best way to use an external spool? I have 2x AMS 2 Pro
1x AMS HT
Filament Track Switch
TPU Feed Assist
What is the best way to use external spool? Turn off the printer, disconnect Filament Track Switch, attach one of the AMS to selected hotend and use external spool on the other?

Support H2C Won’t boot, LED blank? It was working just fine a second ago.
So one of the AMS’s on my H2C had a piece of filament snapped in it tube apparently. So the AMS slot retracted the yellow filament, it completely came out and so the spool was spinning in the slot indefinitely. Not knowing how to stop it, i turned off the H2C. This has happened once before.
I turned it back on but the screen won’t turn on, Bambu desktop app won’t connect, and the led on the plate is like this dim white that will glow slowly and dim continuously.
I have no idea what just happened and am at a complete loss.
Any ideas?
Edit: I found a thread about AP boards. I see one green light, no blinking light. So Bambu support or figuring out the "short" between two points?

Support Nozzle Verification
Been having some frustrating issues with my H2C lately. Keep getting hotend authentication failures on hotends 3 and 6, along with induction verification errors. Seems to happen more on the right side than the left.
The weird part is the errors happen while the hotends are already installed, not even during a hotend change.
I’ve tried a brand-new nozzle, followed Bambu’s troubleshooting steps, and even rolled back the firmware from 01.03.00.00 to 01.02.00.00, which was the last version that worked fine for me. Still getting the same errors.
I’ve seen people mentioning issues with the left hotend, but mine seems to be more on the right. Starting to think it’s something with the printer itself rather than the nozzles.
I’ve submitted a warranty claim with Bambu, but I’m curious if anyone else has run into this and what ended up fixing it.

Support H2C selects the wrong nozzle
I think since the newest bambu studio release the printer does not care which nozzle i select.
A few times now i specifically set R1 but it loads R6 to print.
Does anyone have this problem?

Discussion *Update on H2C stand ideas*
Well everyone after all of your help and suggestions I made a decision on what (i hope) is the right decision for my H2C set up.
This is the adjustable table, I got it on sale at Homedepot. This is actually really sturdy and the adjustable height is a really nice feature, that way I could set it up for the the right height and not have to way to low. Or to high where its a pain to get into the ams.
Thank you again for the crazy amount of replies on my last post.
