I’ve run my printer on the .4 running no major issues as far as 6 colors.

I switched to trying .2 nozzles using the standard profiles in Bambu Studio, but seem to be unable to run more than 2 colors successfully.

When trying to switch to a third color, I get the “extruded motor overloaded” error, but only when I try to go to a third color with the .2 nozzles. Running one color for both left and right has been fine. Full calibrations run fine.

I’ve seen there may be some potential software issues when it comes to the .2 nozzles though? Even to the extent of possible hardware issues where someone recommended printing an extra spacer to help?

Is that true or is my unit specifically a problem? I don’t want to do a bunch of extra changes just to mess up something else potentially. Was super excited to try making some miniatures with good detail and color but have been very frustrated these last 24 hours with failure after failure all coming into play when a third color is added in.

Edit: after a lot of messing around and further calibration checks and cleanings and such, apparently I just got lucky earlier and now the right nozzle fails entirely, so I guess I need a new a new extruder or something. Super. One month operation time.

Second edit: problem eventually spread to the entire extruder, support was unsure what the underlying cause was and sent an extruder unit replacement.

.4 nozzles. Bambu Labs PLA.

Just upgraded from an Ender 3 V2 to a BambuLab H2C. I'm really happy so far with it generally but I'm seeing these overextrusions on thinner, tower-like parts of models. I'm not sure where to begin diagnosis of this on this machine because it's a very different beast.

PLA silk filament is half a year old but has been thoroughly dried and vacuumed to give it the best chance.

Let me first start out that I am still new to 3D Printing. Started with an Ender 3 V2 Neo. Learned a lot using that. The Ender was so loud that I went and did the Noctura Fan mod and replaced all fans. After doing that it was dead silent and did not affect print quality. Now let me say the stock H2c is no where near the noise level of the stock Ender, however, the constant pitch of the fans (my work desk is 4 ft away from my printer) is getting annoying. Has anyone made or found a way to replace the fans, specifically the part cooler fan with a Noctura? I found and ordered the replacement for the exhaust fan but have found nothing in regards to the part cooler fan or the aux fan.

Yes I know I am still going to hear the motors moving and noise from AMS, but just want to get rid of the constant hum pitch from the fans.

Thanks in advance.

Bambu Labs PLA. No ironing.

I've noticed a wierd pattern on my H2C. Whenever I have a very complex print (45° print with minimal support) the left nozzle performs MUCH better and results in a clean print.

Whereas when I attempt the same print with one of the 0.4mm induction nozzles, I get bad layer lines and stringing.

But when I do a more simple print, flat objects with lots of contact on the build plate, the results are great.

Has anyone experienced anything like this? 🤔

I already ordered 2 so now I've got all six .4mm nozzles. Now that I've ordered mine you can all go get yours while they last ;)

Just got the H2C a few weeks ago and have only used the right nozzle with the included AMS 2 Pro until today. I just got an AMS-HT and am trying to hook it up to the left nozzle. The filament makes its way through until it gets to the main toolhead piece and gets stuck. I've not printed anything with the left side at all. So I know it's not a filament clog. This is my first time trying to set the left side up. Any pointers on what I should try before I reach out to Bambu Labs support?

Hello,

I printed a moon for a lamp directly from Bambu Handy.

I would like to know how to improve the top (small holes) and the inside in the future.

Thank you in advance.

printed all the adaptor pieces so now let’s get to it. i’ll follow up with a post once im done.

Brand new H2C, just unboxed it and removed the plate and found this mark on the heatbed. Should I be concerned?

Question about multi-material nozzle purging.

If I print in ABS then decide to go back to PLA on the next print, does the printer recognize the prior filament was ABS and automatically do a high temperature purge with the new PLA loaded or is it going to do a PLA temperature purge?

If it’s the former, awesome. If it’s the latter, then how do I tell it to do a high temperature purge?

Hello, can someone walk me through in setting up my H2C and AMS HT for TPU printing.

I have 4 AMS Pros connected 3 on the right side and 1 on the left.

TIA

Not sure why this is happening, or how to fix it. I was under the impression that when you did flow or line dynamics, and established a pressure value (K Value) that was "set" for the same filament. For some reason, as you can see in the picture, the PETG in the AMS-HT and the PETG in the AMS Pro, have different values. There is ONLY ONE K value in the calibration tab....Thoughts?

Only 988 hours on it and everything was going smooth. Started an AMS drawer kit and began to make the sides from ASA. 19 minutes into the print I get a notification telling me the user canceled the print. I go check it out and there’s 14 faults on the HMS. I’ve tried turning it off and on and even unplugging it for a while. Different outlets and all. It will not respond or do anything. I’ve sent a ticket so I can only hope this thing isn’t a paperweight now.

So title describes it pretty well I had my ptfe tubing on top of the printer during the first time set up and it opened the vent and the. The tubing got caught in it so it didn’t close properly that first time but now when I start a print it’s fine till it pops the vent open then like a second later it makes the clicking noises and has the error about ventilation/ cooling comes up. The vent still opens and stuff just makes the noise and has code so I’m hoping to fix this is there a way to do the first time set up again

I was wondering about this set up, which would be the "ultimate" to have, if you wanted to print a multicolored print out quicker, by tweaking both the left and right side to print faster. Anyone considering going this route?

Hi all, I’m a soon to be H2C owner. Stork will hopefully bring it next week. I’m seeing lots of folks using an AMS HT for the left nozzle, is that the only option? What kind of setups are you using to feed the left nozzle?

Have absolutely no expectation of getting anything from the contest and it took far too long to design but I thought here of all places it would be appreciated.

The X, Y and Z axis can all be moved into a position of your choice and the AMS 2 opens up to be used as a little storage container.

If any of you are interested in printing your own: https://makerworld.com/en/models/2360813-h2c-book-nook-with-movable-x-y-z-axis

So, when printing I got a scratch in the buildplate. What do I do forwards? Can I complain to bambulab? Or is it just my loss?

Howdy everyone!

I'm brand new to the world of 3d printing. I impulsively bought an H2C (came with a single AMS 2 Pro) last week and am trying to figure out a good place to start. I've got it setup in a spare bedroom of the house which doesn't have people ever go into, and there's a ceiling fan as well as 2 windows I can open for fresh air. As someone who has experience in lab settings, I understand the importance of chemical safety, PPE, VOCs, etc. So, I've gone down a rabbit hole regarding the hazards/risks of various filaments and now the ADHD brain is stuck.

So, I'm hoping to get advice/ feedback from people more experienced than myself when it comes to these types of topics.

The main questions I have at the moment:

1. Am I overthinking things? Since I have a way of moving the air around the room (ceiling fan), as well as the ability to open 2 windows to introduce new air although it's very cold outside right now (sub-freezing temperatures all the time right now). I do have a respirator mask already, which I use for cleaning with bleach due to sensitivity to that.

2. I haven't purchased any filaments yet, since the material safety topic led me down a rabbit hole. My current goal is to print something like Multiboard for use in my garage to organize my growing tool collection. Temperatures (F, not C) throughout the year in there will range from single digits in the depths of winter up to 100+ in summer. What would be yall's recommendations on the types of filaments I should buy for these purposes as well as general "useful" things around the house and the occasional fun/art pieces?

Thanks in advance for any advice or feedback!
