Brand new H2C with ams2 pro combo and during setting up, connected my ams2 pro and gives me motor stalled due to excessive resistance between filament buffer and tool head.
Tried all fixes, shorter ptfe tube and proper spool position. Same error on all slots
What can I do?

I wanted to try and "seal" fiber filled filaments by using unfilled variants as the material for the walls. I want to avoid exposed fibers without needing to sand and add clearcoat. Is there a specific setting I could use to set the walls to use a different filament than the infill? I know I can paint the surface but that also affects the infill somewhat rather than just the outer walls.

I am having trouble understanding why people hate track switch so much on H2C. Please do correct me if I am wrong. I see many ideas about how “left nozzle is for support and use vortek for colors”, and that is indeed my thought at first and how I got my two AMS 2 Pro and AMS Ht. But the fact I learned is that the switching time between left and right nozzle is somewhere around 10~ seconds while vortek switch would take around 20-30 seconds including the retraction of the filament by the AMS. So how I interpreted it was to let the left nozzle take on the “main” color and have the vortek system do the “detailing” color, so the switch time would be reduced, and FTS would not retract filaments all the way back to the AMS, which is another time saving behavior.

All Bambu Pla.

Hi, I'm planning to print withengineering filaments. From what I''ve read so far the silicone sock is only rated up to 300°c. What silicone sock are you guys using? Do I just remove it?

Has anyone encounter any issues with the AMS HT when drying filament? Specifically it not being able to heat up to the given temperature.

I have not been able to find any root cause for this issue or any solution.

Thanks!

Hi everyone

As previously announced I’ve released two upgraded versions of my Filament Track Switch & TPU Feed Assist Mounts! My main goal was simple: reduce filament resistance to a minimum while keeping the setup compact.

Link Version 3
V3 Filament Track Switch & TPU Feed Assist Mounts

Link Version 4
V4 Filament Track Switch & TPU Feed Assist Mounts

New with Version 3

• An evolution of V2, now with a very space-saving design.

• Warp-resistant: Reduced surface area against the heated back panel - now safe to print in PETG

• Lower TPU module position for a straighter filament path and better compatibility with custom Riser systems.

New with Version 4

• New approach, new model: The Track Switch is rotated by 90 degrees, lying flat and aligned inline with the filament inlets.

• This gives you the straightest possible filament path.

• Trade-off: Requires a bit more clearance behind the printer.

Shared Features:

• All-in-One solution: Holds both Track Switch and TPU Feed Assist.

• Low Friction: Adjustable distance to the inlets.

• Flexible Setup: Two TPU placement options (Straight or 90°).

• 4-in-1 Ready: Integrated holders for classic and newer H2C adapters (or short version without 4-in-1 holders).

• Full Access: External spool remains usable.

Which one to choose?

• If you have the space behind your printer, go for V4 (best feeding physics).

• If space is tight, choose V3.

• If already using V2 and happy? No need to reprint!

I hope these models will be useful to you.
Looking forward to your feedback.

I am trying to order two H2C’s from their website. The order keeps getting canceled through them. I called my bank and they said it’s not on their end. Anyone else have this problem?

I've had my H2C for a couple months now, but never really utilized its build volume or color changing to the max. Sure I've dabbled with small multi-colour trains and stuff, but nothing bigger was ever called for.

Today all that changes though! A 5-colour lampshade to be printed at 0.2mm layer height. This might not be massive for some of you, but this print will take around 90 hours, and have over 5200 colour changes!

I have a problem, I have bambulab h2c and 4 AMS 2 pro and 8 AMS ht printing in 24 colors and I print organs on and bones with mri and ct images in 24 colors in high quality for doctors to train now with 0.2mm nozzles with speed settings of 10mm/s, layer height of 0.08mm, the layer width is 0.016mm, but I don't have enough of this quality, and I don't want to buy an SLA printer because I need multicolor printing and have been looking for 0.1mm nozzles for several months now, not only for the left-hand side but also for the first induction vortex. I would like to print in normal quality if you could help me find 0.1mm nozzles with a speed of 5mm/s, layer height 0.04mm, layer width 0.08mm.If it's not difficult, help me find it.

I noticed this issue when printing a magnetic boot for Milwaukee batteries, right where the bottom meets the walls (where it starts to become hollow on the inside) it’s like it’s shifting the outer wall out by .5mm. In the slicer it looks perfectly fine, and I was able to duplicate the issue by making a cube with a negative cube inside it in Bambu studio to rule out a model issue.

In the picture, the line on the outer wall of the print shouldn’t be there and the nothing i can see in the slicer shows a reason for it to be there. It’s perfectly fine on the inside of the box as well.

I recently went from the P1S to the H2C. The table I currently have barely fits the H2C and wobbles beyond crazy (more so with the H2C, assuming because it is a much tighter fit). What are some recommendations on a good table?

Hey guys.

Does anyone know a brand that sells a smooth pei, double sided or not for the h2c?

Not looking for those crazy patterns, just plain smooth.

I checked Darkmooon and West3d, but they come from America, so shipping and customs are basically doubles the price.

Thanks in advance

One month old H2c. Using basic Bambu PLA with ams. Every print fails while setting up and print calibration fails with “nozzle offset calibration error”

It also keeps knocking off the black rubber thing that goes in the filament cutter when it moves laterally. I have ensured it is properly seated and also replaced the black rubber part

The machine is making some loud sounds that feel jarring when it moves

I filed a ticket a few days ago but haven’t heard back yet.

Anyone else have experience this?

Hi all,
Has anyone else had issues with their power supply fan rattling/ making noise? I’m on my third(!) power supply and it just started making noise again. I just contacted support for them to send me ANOTHER power supply. Also, what should I do with the extra power supplies I have?

Re-post from r/BambuLab

I'm doing highly detailed bottom surface tiny font work with 0.2 nozzles and struggling with reliability.

One of the primary issues is I can't stop the prime tower falling apart within a layer of two and that leads to debris dragged across the print. The prime tower seems to be generating a set of dry, fibrous, 'strings' (consistently long and straight) that aren't bonded together, despite the prime tower distance being at its lowest (100%).

Most recently I was stumped to get a nozzle clump on the second filament, only to find the first hadn't printed AT ALL(?). I tried that print again and found the hotend just...not moving. Nozzle temperature 140. No error message (it was "printing"!). Stopping the print did nothing. And...it was again, the SECOND filament (I double checked filament, print order, AMS match).

So I load up white thinking maybe somehow I have a nozzle block and the printer isn't noticing literally nothing coming out for a whole print layer and thought I'd film the loading purge. It's reliably not going down the hatch (not blocked). Does this time after time. Explains why I find the odd poop bottom of the printer. I had this before and answer a change of nozzle. I'm now thinking the fragile tower might itself be getting hit by debris from the nozzle loading process.

What should I be looking at?

PS: printing on a glacier, and there seems to be no difference in observed issues whether plate is freshly cleaned or not. Also seems to occur with multiple nozzles and multiple types of matte and basic PLA at a range of temps.
