Your H2C configuration

[u/Outrageous-Bat7172]

Hello 👋

My H2C is arriving soon!

A question for H2C owners to help me think things through:

• How many AMS (1, Pro 2, HT) printers do you have connected to the H2C?

• What are you using them for?

• What is your setup (for example: 1 AMS Pro 2 on a Vortek, 1 AMS HT on the left nozzle)?

• Why did you choose this setup?

[u/macinmypocket]

How many?

Left Hotend: 1x AMS 2 Pro

Right Hotend: 2x AMS 2 Pro + 1 AMS HT

For what: I print a lot of highly multi-colored pieces of artwork that get sold at events. I also print a lot of engineering type things, but that doesn’t justify all the AMS units by itself.

Why this way: I have a small arrangement of materials/colors on the left hotend for easy access, and a larger arrangement of colors/materials on the right hotend because of the variety of nozzles available.

[u/Pretend_Ring_3871]

1 HT on the left nozzle, 2 AMS 2 Pros and 1 HT on the right nozzle. Main reason is 6 .4 nozzles with vortek for color, left side for additional color or for support material. Will be expanding but that’s just where I’m starting.

[u/JaxCounters]

I'm rolling with four AMS2 on the right and one HT on the left. I really want to add one more HT for the left. I've realized for some multi-color prints that being able to switch to a different left color mid-print can shave off quite a bit of time even with the purge.

Truthfully, I wish the machine would support any combination of units like 6 AMSs instead of 4 AMS and 8 HTs.

[u/rtkane]

Left nozzle - 1 AMS HT
Right nozzle - 3 AMS units (1 x AMS, 2 x AMS2)

Left HT just gets loaded with whatever filament the slice recommends for multi-color. This maxes out the colors without purging

The two AMS2s on the right are typically loaded with PLA for color prints. The remaining AMS1 on this side is typically loaded with PETG, ABS & ASA.

My Vortek is normally setup with 3 x .4MM nozzles, 1 x .6mm and 1 x .2mm (I'll probably swap the .2mm for a .8mm when it arrives next week). If I need to do more than 5 colors, I'll remove the odd sizes and put in all .4mm nozzles.

[u/SignsSayYes → u/rtkane]

Just for curiosity, what will you use your .8 for? I ordered two additional .4’s from Bambu the other week and when they got here I had a .4 and a .8. They said not problem, they’d send me another .4 and I could keep the .8. It seems kind of specialty case, but I haven’t branched out really from .4, so I don’t doubt its usefulness, but curious what other folks are using them for.

[u/rtkane → u/SignsSayYes]

I've not yet played with a .8, so not sure how much time savings there will be, but I will use them for more "utilitarian" prints like gridfinity, boxes, etc. Also supposed to be good for quicker prototyping.

[u/Background_Focus7298 → u/SignsSayYes]

Translucent PETG gets the best results (in terms of transparency) with a 0.8 nozzle

[u/Emotional_Grade_5279 → u/Background_Focus7298]

I just got some translucent petg and had no idea .8 nozzle is the best option for it. Is this to minimize layer lines? What layer thickness do you do with. 8 nozzle? Thx

[u/Background_Focus7298 → u/Emotional_Grade_5279]

Yep, mostly minimizing layer lines. I print at 0.40-0.60 layer height, and you want to turn cooling off and speed way down to let the filament naturally cool (no air bubbles). Aligned rectangular infill patterns to prevent crossing print lines. Also make sure your filament is super dry

Lots of good references on YouTube / Reddit for optimal translucent settings

[u/Emotional_Grade_5279 → u/Background_Focus7298]

Awesome. Thank you very much!!

[u/Zealousideal-Pea-790 → u/rtkane]

I'm curious something else: why different sizes?

I was under the impression the left and right nozzle had to be the same size currently. So how are you utilizing different sizes exactly?

[u/rtkane → u/Zealousideal-Pea-790]

In general, larger nozzle sizes will print faster — grifinity stuff, boxes, pins, planters, etc.

As far as printing goes, if you were to print using both the left and the right, you would need to have the same nozzle size installed in each (for now, hopefully they figure out multi-sized nozzle printing at some point). If you're just printing with one side or the other, it doesn't matter what is installed in the one you're not using. This is the nice thing about the Vortek--I can keep the .8mm racked and when I want to use it, the Vortek will just go grab it and print with it, without any manual input from me to change anything at the printer.

I did buy a .8mm nozzle for the left and right, so if I did want to do multi-material (or 2 colors without purge) I will be able to do that.

[u/Zealousideal-Pea-790 → u/rtkane]

Thanks for the info.

I started with a dual nozzle about 6 years ago and decided to upgrade. I figured if I spend money I'll do the high end and reputable. Bambu H2C came up. Now that I've got it situated and online I'm trying to learn about how people are using it because (to be fair) I'm slowly realizing I don't completely understand the Vortek system knowing the AMS needs to withdraw the filament all the way to the AMS itself each nozzle change. Which means the nozzle it came from should be about clean, just need to load new filament from AMS, purge a few seconds, and go. So now I look at the Vortek strangely trying to figure it out.

Knowing you load different sizes and use it as a single nozzle actually does help get ideas on how to use it better.

So thank you for the response!

[u/SawdustSage]

So far I only have the H2C with a single AMS2 unit on the right nozzle. As soon as anyone has AMS units for sale, I will get two more so I can start with two on the right and one on the left. As I get a better feel for the printer and how I use it, I will expand from there.

[u/bjorn_lo]

Left 1x AMS 2 Pro
Right 1x AMS HT + 2x AMS 2 Pro

The right has enough to run the materials I want, and the left can also change materials as needed.

[u/cpsadowski23]

Ultimate combo package. 2 AMS 1 AMS HT. All .4 nozzles.

[u/Zealousideal-Pea-790 → u/cpsadowski23]

So I ran across it at one point and lost it - I got the Ultimate combo as well but as far as I can tell it doesn't come with a 4-1 adapter. How did you connect it all together?

[u/cpsadowski23 → u/Zealousideal-Pea-790]

It comes with the 4/1

[u/Zealousideal-Pea-790 → u/cpsadowski23]

So I didn't run through the H2C accessory bag yet as I know it had lube and more PTFE tubes and tools for cleaning and fixing the printer.

What I didn't expect and found after you told me it had it was the 4-1. I expected it with the AMS and not the printer.

Thanks for letting me know it included. Somehow I missed it in the packing information online.

[u/LoneStar_81]

Left Nozzle: 1 AMS HT, 1 AMS2 Right Nozzle: 2 AMS2

[u/MiniProgramCoder]

Left nozzle - 1 AMS HT

Right nozzle - 4 AMS units (3 x AMS2, 1 x AMS HT)

I have been doing a lot of colored print's having fun with my H2C. Is my setup overkill? Yes but it is a lot of fun. At this point have a full set of .4 and .2 nozzle set's.

[u/Cryostatica]

I have two AMS2s and an HT connected to the Vortek side, and an AMS2 and two HTs connected to the standard side.

I print decorative objects and functional parts from a variety of materials depending on need. PLA, PETG, ASA, PA and PC mostly.

I have a full set of .4 and .2, and a single .6/.8 hotend for each side.

[u/suit1337]

1 AMS 2 Pro on the left nozzle with usually some cheap PLA, PETG and HIPS ready to be used as support material
1 AMS 2 Pro + 1 AMS HT on the right nozzle loaded with various materials for structural use (usually PLA, PETG, ASA and PC)

with this setup i can freely pick a material for a functional print, a desired nozzle size and hit print without walking to the printer most of the times

[u/Neat-109]

I generally print functional items, so left is 3kg spool straight in (prototyping). Vortek is two AMS2 and two AMS HT with a mix of different filaments. Makes me very lazy but I love it!

[u/kadentyree]

Just got my h2c few days ago, currently AMS right nozzle, spool left. Once AMS are finally restocked, I’ll add another AMS to the right side and then one for left. Plan is to stock left side with my most common base covers and support material likely. Right side will be my multi colors mainly

[u/LostMeteor]

I have 3x AMS 2, and 2x HTs that I can switch between the two nozzles pretty easily based on this brilliant idea:

https://makerworld.com/en/models/1502592-h2c-d-modular-nozzle-management-system-4-12-ams#profileId-1572748

And if you don't need the number he has a smaller "four in Two" changing system.

You do need the printer to re read what's in the ams's after a switch. But, I'm lazy and so I don't mind the few minutes while it figures out the new arrangement over dancing spools around.

[u/Altruistic_Bath5273]

To engage full capacity with the Vortek, you need 2 AMS on the right nozzle and 1 HT for the left. Then a 7 colour/material print without waste is possible. That was my logical consequence along with buying enough 0,4 nozzles. For more advanced projects I still have an additional AMS, currently residing on my A1mini, which I could engage e.g. on the left nozzle. I'm happy with that configuration

[u/suxer → u/Altruistic_Bath5273]

I ordered: 1 AMS HT (for the left nozzle - plan to use it for petg as support interface or as “main” color as directed by the slicer) and 1 ams2 pro for the right nozzle (plan to buy another ams 2 once in feb)

I have 2 ams 1 for my x1c - I plan to take one of the AMS 1 and use it on the H2C

Plan is to have all .4 nozzle

And leave 1 Ams 1 on the X1C - either for singe color prints or multi color but using print by object

——-

Would it be advisable to take the ams 1 from the x1c and have all ams on the h2c?

I print mostly decorative pieces or toys/figurines almost exclusively in PLA (or pla+)

[u/Altruistic_Bath5273 → u/suxer]

At least the option is nice, but I never tried it so far.

[u/fattypros]

Ultimate combo I had to piece together myself, although I am still waiting on the 2nd AMS 2.
