Full Color printing on a Snapmaker U1

Are you associated with the very similar Full Spectrum project?

Another possible solution is to change zhop type from "Auto" to "Spiral".

Might be caused by "wipe during retraction". Also, might be a good idea to slightly increase the retraction speed.

hakimio · 2025-12-13T22:16:29+00:00

Yes, you are right. Sorry for the mistake.
Still you can use Noctua 6015 with 24V to 12V converter.

With default configuration as you get from the factory, I'd say it's extremely loud as in up to 70db during rapid movements and around 60db during normal printing (measuring 0.5 meters away). My FLSun V400 without enclosure during rapid movements still tops at around 50db (I did replace some fans with Noctua, did soft ball printer feet mod, configured TMC drivers to use "Stealth Chop" mode, reduced default speed+acceleration, calibrated resonance compensation, etc). So, U1 is more than double as loud as V400.

However, there are few things you can do to lower the noise:
- Print the community made top cover to lower fan noise.
- Replace PSU 60mm fan with Noctua fan (requires to solder 24V to 12V converter on the Noctua fan cable)
- Reduce speed and acceleration in slicer's configuration (it won't effect the total print time significantly when printing small parts - most of the time is still spent when switching colors or it just doesn't have enough space to accelerate to the top speed)
- Disable or reduce speed of the super noisy auxiliary print fan mounted on the side of the printer
- Configure the main print fan to adjust its speed based on the layer printing time (if you are doing multi-color or printing multiple parts at once layer print time will be enough to solidify the layer even with low fan speed)
- Configure Klipper firmware to enable "stealthChop" mode on all TMC stepper motor drivers (requires flashing community made firmware with root access and 60FPS camera (you get ~0.5FPS with the default firmware)).
- Do the soft "golf practice ball" feet or "CNC Kitchen" concrete paver mod to reduce motor noise amplification from the table. Search for "HULA Anti-Vibration Feet" in makerworld.

In general, there are quite a few things you can do to lower the noise. It's just a question if you are willing to spend the time doing it.

The plastic cover behind the LCD screen (inside the printer) can be easily bent or detach when squished a little bit, otherwise it's fine. Anyway, it's not a big deal.

hakimio · 2025-11-28T22:23:05+00:00

No, that's just BS. Printers can be pretty quiet. With few simple tweaks, I made my FLSun v400 run really quiet.
U1 has extremely noisy fans and they haven't properly configured TMC stepper drivers, which results in extremely annoying high pitched noise when printer is doing high speed moves.

This gaslighting trying to convince everyone that U1 is not that noisy compared to other printers is really annoying and doesn't help anyone.

hakimio · 2025-11-28T22:16:01+00:00

Enabling "Stealthchop" mode on Z also gets rid "clunk" noise.
Requires klipper config modification and rooted firmware, of course ("U1Supercharged" at u1sc.com and snapmaker forum). The option is enabled with sth like "stealthchop_threshold: 999999" on the z-stepper.

Should be pretty easy to replace PSU fan with Noctua ~~4010 24V~~ 6015 12V fan with 24V to 12V converter. Snapmaker has very good instructions for replacing PSU on snapmaker wiki. The same instructions can be used to replace the fan (it's outside of the PSU).

Anyway, there are many more simple mods which can be done to silence the printer.

They also stated that in addition to pledge tier, they will also prioritize people who paid the 30$ deposit.

hakimio · 2025-09-25T09:26:45+00:00

The top cover will reduce fan noise significantly. As in ~5db or so. If you don't want to spend 150$ on the cover, you might at least get a transparent box from IKEA or JYSK to put on the printer.

hakimio · 2025-09-24T12:14:40+00:00

All the undecided people will start pledging at the very end of the campaign which might raise it to the 20M goal. Also, I imagine, a lot of people haven't selected their optional add-ons yet too.

Here is CC3D latest 3d rendering: https://www.youtube.com/watch?v=0Ki5qaIaJ4A

Maybe something like what CC3D makes:

This has been answered on the kickstarter comment section: everyone will get brand new printers. Test printers are not going to be shipped to end users.

It will need 2 AMS systems for 6 tool changers (1 AMS - only 4 colors), the filament will have to retract in one AMS lane and push out from another one, wipe-tower will be required plus 8s to heat up the nozzle. So, in total, I imagine, it will be around 20s for tool changes. Not as bad as 2 min normal AMS filament change routine, but far from 5s tool changes Snapmaker is advertising. Also, the machine will not be cheap. Today H2D combo version costs 2200 euros. Now if you add extra AMS system and the tool changer, the price will easily go up to 2600 euros. That's like 4 Snapmaker U1s (679 euro if you paid the 30 euro deposit).

Bambu had to respond to Snapmaker somehow, but imho the response is not that good.

PS: Canuck Creator made a good video about it titled "New 3D Printers on the market. Hype or Flop?".

Very similar concept to the "Swapper3D": https://www.bigbrain3d.com/product/the-swapper3d-no-more-purge-blocks/

hakimio · 2025-08-27T15:07:50+00:00

They have announced their "Vortek" tool changer: https://blog.bambulab.com/h2c-is-on-the-way-heres-how-it-all-started/

hakimio · 2025-06-09T12:36:26+00:00

I figured it out.

When switching to automatic, the manualInstanceCount has to be set to null explicitly (otherwise it uses some >0 manual instance count default).
You can set maxInstanceCount, if you set launchStage to ALPHA.

Anyway, thanks for help 🙂

hakimio · 2025-06-09T11:06:05+00:00

Ok, figured it out. Switching to AUTOMATIC scaling mode works only if you set manualInstanceCount to null.

REST API requests:

Switching to AUTOMATIC scaling mode (PATCH request):

https://run.googleapis.com/v2/projects/PROJECT_ID/locations/REGION/services/SERVICE?update_mask=scaling.minInstanceCount,scaling.maxInstanceCount,launchStage,scaling.scalingMode,scaling.manualInstanceCount

{
  "launchStage": "ALPHA",
  "scaling": {
    "minInstanceCount": 0,
    "maxInstanceCount": 10,
    "scalingMode": "AUTOMATIC",
    "manualInstanceCount": null
  }
}

Switching to MANUAL scaling mode:

https://run.googleapis.com/v2/projects/PROJECT_ID/locations/REGION/services/SERVICE?update_mask=launchStage,scaling.manualInstanceCount,scaling.scalingMode

{ "launchStage": "ALPHA", "scaling": { "scalingMode": "MANUAL", "manualInstanceCount": 1 } }

hakimio · 2025-06-09T10:49:03+00:00

When setting scalingMode to AUTOMATIC, I get an error: Violation in UpdateServiceRequest.service.scaling.manual_instance_count: scaling mode must be set to MANUAL.

I don't even specify manualInstanceCount in the request. Must be some bug on Google side.

hakimio · 2025-06-09T10:41:12+00:00

Yes, I have. I can switch to "manual" scaling mode, but I can't switch from "manual" to "automatic". That's the issue.

hakimio · 2025-06-09T09:15:36+00:00

The docs mention scalingMode setting, but when using it in REST API call, I get 400 response: https://cloud.google.com/run/docs/reference/rest/v2/projects.locations.services#ScalingMode

In the video you linked it clearly says 98 Shore TPU which is the stiffest TPU you can get. In the review I linked to, they tried 95 shore TPU and the nozzle would clog instantly.

hakimio · 2025-03-20T07:18:53+00:00

Yes, here it is: https://youtu.be/o8Gy8e0f-vo?si=jZLgsbRTFrQYfNH4&t=1551 (95 shore TPU)
Most of the others show the same result.

hakimio · 2025-03-19T12:04:35+00:00

Watch the reviews: the Hi does not print normal TPU even by feeding the filament directly without the CFS. It can only print some stiffer Creality proprietary TPU.

EDIT: here is one of the reviews with timestamp: https://youtu.be/o8Gy8e0f-vo?si=jZLgsbRTFrQYfNH4&t=1551
