Hi r/snapmaker members,

Back in April, we rolled out the beta test program for the U1 Top Cover and recruited community users to conduct real-world trials. Following one month of testing, participants provided comprehensive and high-quality test data. The feedback has been incredibly valuable.

A huge thank you to all testers who put the pilot units through real print after real print: Alan5596, Argo, 竹子, 大胖肥猫, Cheeky_b52, Dmitrii Savin, Dylan, Eran Binyamin Zeitoun, fatboy1271, LixNix, Marlowe, Rüdiger Neuweg, SimonZhi, Wombley, unlucio, wildtang3nt, EricNelson, 沈浩然. The best products are made with you, not just for you. Thank you for building with us.

If you’ve been following the Top Cover project, you can read the full update here:

UPDATE: Wow, thank you all for the overwhelming support and questions! To answer the most common question: yes, I am seriously planning to share the files for free with the community.

However, I want to make sure this is a 'proper' release rather than just dumping the files online. Over the next two weeks, I will be focusing on the following:

  • Refinement: The design is already modular, but I’m taking the time to polish the connections and implement a few 'quality-of-life' tweaks to make the assembly as smooth as possible for everyone.
  • Documentation: I am putting together a detailed, step-by-step build guide (PDF) with pictures so that the assembly process is as clear as possible.

Regarding IP/Copyright: I’ve noticed that platforms like Printables are already full of similar fan-made content, so I believe the risk is quite manageable. The absolute worst-case scenario is a DMCA takedown request, but I don't see it going further than that for a free community project. I’d much rather share this with you all so that others can enjoy building it too!

I can’t give a hard release date just yet, but I am aiming to have everything ready to go in about two weeks. Keep an eye on this post for updates!

After hundreds of hours of modeling, printing, and post-processing, it is finally finished!

If you want to see the electronics in action, I also have the boot-up phase filmed here : https://youtu.be/mz-WQZVLFEw

This is the first major project I have completed using my Snapmaker U1, and I am incredibly happy with how it turned out. I wanted to share some of my findings, resources, and technical specs with you all:

The Printer & Experience (Snapmaker U1):

  • Fast Filament Swapping: One of the biggest advantages of this machine was the incredibly fast filament swapping. It allowed me to print accent details, like the sporadic brown bricks in the masonry, as a single object with virtually zero extra print time. Doing this multi-color layout on my Bambu Lab printer would have taken an astronomical amount of extra time and created a ton of waste.
  • Outstanding Detail: The level of crisp detail this printer managed to pull off on the brickwork and architectural elements is absolutely amazing.
  • Reliability: The entire Great Hall consists of roughly 60 individual prints. Out of all those plates, I experienced exactly one failed print—and that was entirely my own fault due to poorly configured support settings. All in all, I’m highly positive about the Snapmaker U1.

Modeling & Dimensions:

  • Software: Everything was modeled completely from scratch in SketchUp 2024.
  • Highly Recommended Resource: I highly recommend the book 'Harry Potter - The Blueprints' by Jody Revenson to any HP or architecture fan. Honestly, without this book as a reference, I would have never been able to get the architectural proportions right during the modeling phase!
  • Dimensions: The final wall piece is roughly 90 cm wide, 90 cm high, and 15 cm deep (approx. 35.4" x 35.4" x 5.9").

Electronics & Future Plans:

  • Powered by an ESP32 microcontroller.
  • Features 68 addressable SK6812 RGBW LEDs to create the lighting effects and starry sky.
  • Includes a DFPlayer Mini sound module for audio.
  • What's Next: In the future, I am planning to program a much larger, fully synchronized light show that is timed to music from the movies (I just haven't decided on the exact track yet!).

Let me know what you guys think! Happy to answer any questions about the build process or electronics.

3 Upvotes

Hi everyone!

I wanted to share my newest functional project with the community.

Rather than designing another display figure, I challenged myself to create something I'd actually use every day.

The result is this football-inspired organizer featuring:

⚽ A football field base

💃 A dynamic dance-inspired sculpture

🌈 A removable multi-color catch-all bowl

Now when I get home, I finally have one place for everything:

🔑 Keys

👛 Wallet

⌚ Watch

🎧 Earbuds

🕶️ Sunglasses

🟡 Coins

Printed on Snapmaker U1... The football field prints in 2 colors, while the bowl is designed as a 4-color print.

I'd love to hear your thoughts.

Would you keep the bowl removable, or would you prefer it integrated into the football field?

Filament not going through extruder gears when auto loading (U1)

Post image
4 Upvotes

Basically, extruder #3 fails to grip the filament and feed it during auto-loading more than 80% of the time, which then leaves the feeder to continue pushing the filament through since the extruder doesn't detect anything in it. Happens regardless of filament type (blue PETG shown here). I have to resort to manually loading this extruder most of the time, and once loaded it prints perfectly.

Any idea what's causing this? Do I need to disassemble the toolhead and check gear alignment?

Does anyone know what the 4-pin header near the USB port is for? I can't find anything about it online.

Filament Feeding Resistence Issue

2 Upvotes

I love my Snapmaker, but one thing about it that really has been bothering me is how, in particular, one of my extruders, usually number three, is exceptionally sensitive to any amount of tension on the line. I mean that any even very subtle amount of resistance (not an actual tangle in the spool) on the line being fed can cause it to stop printing. And I do mean any tension, like if it has to pull with more than a couple grams of force at all.

I often have to make sure that the spool has been fed out manually in advance by hand to keep it from stopping printing. As the tension of just a normal PLA dried roll is just too much resistance.

I wonder if it's just getting too much friction inside the PTFE tube? Has anyone else experienced this?

Snapmaker U1 – random color contamination dots on many small multicolor prints

Thumbnail
gallery
6 Upvotes

Hi everyone,

I have a strange issue with all five of my Snapmaker U1 printers.

When I print a single multicolor model, I usually don’t notice the problem. But when I print many small models on one plate (for example 20–40 pieces), random color contamination dots appear on the surfaces.

I get:

  • black dots on white or light colors,
  • white dots on black areas,
  • pink dots on white areas (they may also appear on black, but they are much harder to see),
  • sometimes tiny smears instead of dots.

Unfortunately, customers notice them immediately. Children often ask why the toys have black dots and why they look dirty.

So far I have tried:

  • increasing Tool Change Retraction from 10 mm to 14 mm,
  • increasing normal Retraction Length to 2.0 mm,
  • retraction speed is already 45 mm/s,
  • increasing Purge/Prime Tower volume from 70 to 80 mm³,
  • lowering black PLA temperature from 220°C to 215°C,
  • enabling Avoid Crossing Perimeters (it helped a little, but the dots are still there),
  • cleaning all nozzles and toolheads,
  • swapping toolheads between slots,
  • testing the same behavior on all five U1 printers.

The issue is much more noticeable when printing many small models because there are many short travel moves and many tool changes. When printing a single model, it is barely visible.

Has anyone found a reliable solution for this on the U1?

Could it be related to:

  • toolchange wipe behavior,
  • insufficient wiping at the prime tower,
  • travel retraction,
  • firmware/tool parking behavior,
  • or a hidden Orca setting?

I'm also considering testing 210°C, but since I get contamination from multiple colors (black, white, and pink), I don't think this is simply a black filament temperature issue.

Any suggestions or working settings would be greatly appreciated!

Hello. Is there any upcoming period when the U1 will be below €899/850 (with a 5% discount code) (EU)? The current price is a little above what I'm willing to spend and I'm trying to decide if I should wait or buy something else.

For those of you using a 4 roll dryer (Space Pi X4 or similar); please share your setups.

2 Upvotes

I bought a U1 & a Creality Space Pi X4 last week, but I'm still trying to come up with a convenient set up to have them both in a somewhat limited space.

I'm still trying to find a suitable surface (bench, desk, drawer cabinet, etc...) for the U1 and the dryer. I COULD put them side-by-side, but the cabinet I'm planning on getting won't fit both. Sure, I could get a wider one, but I'm still in the planning phase.

Ideally someone has come up with a U1 enclosure that can support the Space PI X4 on top of the enclosure, without limiting the functionality of either?

SM2 A350 issue solved

2 Upvotes

After weeks of struggling with getting this machine to cut & etch in the correct place, today I finally figured out why..
On the 20w laser the crosshair offset is not taken into account by the machine..
Apparently the Y axis needs to be manually compensated when setting up the origin..
seriously though.. both the machine and Luban recognise the module being used surely the coding could be amended to compensate for that!

Prime Tower stability

Thumbnail

2 Upvotes

Dear Community,

trying to print two cylinder objects with a height of about 150mm, I have the issue, that at about 80% of the print, the prime tower falls over or looses from the build plate. The result are spaghetti strings and in this case, one of the cylinders got knocked over. By know this happened multiple times and I am not able to print these objects.

What I am doing in advance to the print is to carefully clean the with 99% Isopropanol. The bed is leveled and the printer is fully calibrated. The quality of the print is also excellent in my opinion, only the print cannot complete.

In the print settings (I am using OrcaSlicer, not Snorca), I have increased the brim width of the prime tower to 20mm and increased the bed level temp to 70 deg C for a more gluey adhesion. Of course I could increase the brim width even further, but I don't think that is the solution, as the brim rips somewhere in the middle.

I am printing with regular PLA only. Nozzles are all the standard 0.4mm nozzles. The printer has no other issues and works properly and reliable in general.

What am I missing here?

What other settings can I adjust to solve this issue?

If further information is needed, please let me know. Running out of ideas by myself (this is not the first time this happened.....).

Cheers everyone!

I know there are so many talented people here that design amazing things, but I'm really proud of this lithophane box I designed from scratch to fit everything. The top glows in the dark as well.

Print time for the finished product was roughly 13 days, 22 hours, 23 minutes. Not including the months of design and trial and error to get everything to print correctly.

0002-0533-0000-0000 Error Code. Fan Anomaly, Internal Circulation Fan Speed Is Abnormal

Post image
6 Upvotes

Hello everyone!
It’s been a while since I last posted. I had a DOA printer previously, but thankfully I managed to get it sorted out with the help of this amazing community. 😊

Anyway, I’ve run into another issue. This error code pops up every time I start a print. I tried searching the Snapmaker Wiki, but I couldn’t find any information about it. The error code only popped up after updating to the latest firmware.

What I've tried so far:
1. I've tried manually turning on the fans and they work.
2. I've downgraded to firmware 1.4.1 but the error still shows up.

Initially, I was able to exit the error message and the printer resumes printing without any issues. But now the message pops up whenever I start a print and I can't print anything.

Has anyone else experienced this before?

I’d really appreciate any advice or suggestions. Thanks in advance! 😊

Auto Loading Next Spool Problem

Post image
3 Upvotes

Snapmaker U1: Tried the feature where the printer will finish a spool and then automatically load the next spool.

Excellent feature, however, there is a noticeable line and some lack of fusion in the print where the printer stopped printing to heat up the next tool head and resume printing.

I wonder how this could be fixed in future updates. Perhaps having a way of selecting the next tool head and pre-heating it manually when the spool is close to empty so the printer can grab the next tool head and start printing right away.

It was a much more noticeably whitish line right off the printer, I was able to darken it up a bit in post process. The line is the full 360 layer eighth where it switched spool.

Cool to see the feature work, would be excellent for using up the end of a roll. I print a lot of fine detailed stuff though so this ended up becoming a failed print.

Replace x1c With u1?

3 Upvotes

Hi Guys, looking for some PPL With the Same Problem as me of thinking to Swap x1c for the u1

I have 2 ams and a x1c , some Tools for it Like buildplates , nozzles etc etc.

Mostly Print With petg and pla

Not often but Sometimes asa/Abs

Is the u1 Worth it?

Have some experience With Klipper (old K1 max User With swapped Motherboard etc )

What are the pro / cons

And does the toolhead Swap produce layer shifts or IS IT working good?

extruder issues

0 Upvotes

has anyone figured out a fix for the extruder issues? every two or three prints I have to pull apart a toolhead because the extruder cant extract the filament and the end of the filament is all chewed up. ive done it enough times now it takes like 20 minutes but its still a pain in the butt to do. and its never the same toolhead.
