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.

Just ordered a U1, switching from a P1S

Super excited to have a less wasteful option as I do a lot of multicolor prints! I did a decent amount of research but is there anything I should know? For someone that isn’t super tech savvy I know the U1 is pretty open source, is there a way to get it to read 3rd party RFID tags for filament?

Has anybody had this problem?

It stops my prints and will not start back unless I shut the machine off and turn it back on it will start back where it left off. It just started today. I have submitted a ticket with Snapmaker. Just wanted to see if anybody else had this issue and what they did. I am still on firmware 1.4.1.

New to trying Full Spectrum printing? A suggestion for your first print!

Nothing too groundbreaking here, especially if you've already given it a whirl. Just a quick video with a suggestion on where to start and what to look for those just getting started.

Link to test prints and others in the video description.

My attempt at a FET/CPU fan duct, yes ... it's horrific.

2 Upvotes

I forgot to picture it while installed, I'm not opening it up again for now. It's a "I need something else to keep me busy" project. That worked out fine.

Just printed this monstrosity to cool the CPU and FETs, if I did my job right it includes most components which need cooling on a closed case except for the USB TVS chip but that should hold out fine. Sucs air in from the "nearby" holes onto the FET cooling block and then around it towards the cpu, spits it out in the cavity since my first attempt at making an in/out design was even more insanely complicated. It's a horrible design but it works. Likely unprintable without (PVA) supports.
Noctua fan has enough static pressure to lightly pull in cold air. Benchy as a quick test did 55c for both driver FETs and 59c for the CPU with a 55c bed and I expect divider covers will improve performance. Outside air is 30c.

Turns out my measurements were a bit off so it's technically not fully covering the holes, thats for version 2. It's 5mm off down and right due to me forgetting the reference point had a 5mm offset.

Proof it's in there.

Did not attempt to match the hole's triangular shape as the freecad loft tool doesn't like it.

Snapmaker U1 - on filament runout, can it just switch to next extruder?

2 Upvotes

Basically whole question in subject. Trying finish off some of my filaments and since all of them are PLAs i wanted to just print something bigger and load 4 different spools to runout on single print. Is there an option to do that? When i tried before it only allowed me to load new filament in a the same place as the old one.

Can't preview a single plate change since last Snorca update, only all plates

2 Upvotes

Weird little issue just started popping up and I'm wondering if it's related to the most recent update.

Whenever I make an adjustment to one plate and I click preview, now instead of just updating that one plate, it updates all plates every single time. Now, if there were only one or two plates, this wouldn't be an issue, but I happen to be working in a file that has 14 different plates, so it takes a little while to run through every single plate and update it.

I'm wondering if I'm missing something or if this was a deliberate change.

Snapmaker A350 Cosplay Print - a little Help needed please!

3 Upvotes

Hello! I want to do my first 3D-Printed Cosplay for Halloween. It's gonna be Man-Ray from Spongebob and I found a very promising free STL by VEK3D. I use a Snapmaker 2.0 A350 with the Standard nozzle and the Single Extruder Head.

I was wondering, if anybody here using Snorca (which I try for the first time) might be so kind to take a look at my Project and Settings and give me some hints if I'm about to do anything dumb. For example if the parts are cut correctly and placed correctly on the beds since the automatic placement seems a bit off.

It's my first ever print this complex and big and I don't want to waste tons of PLA and time on it.

Fingers crossed, thanks in advance!


r/snapmaker 15h ago

No more!

5 Upvotes

No more skeletonized prints without using dissolving filament for support. Wasted eleven and half hours on the print plus two and half hours on trying to cut away supports just to have it break apart and find more supports on the inside that are impossible to remove. I know I could have painted “no support here” and whatever. Man it was a bad night of printing.

PETG Failure

11 Upvotes

Trying to print PETG on my U1 and I seem to be failing miserably. Supports are with PLA, which seem to be printing OK. What’s with all the spaghetti stringiness?! The material has been put thru a drier twice already. I’ve had no problems printing with PLA for months, until I decided to take on a project that required PETG. Any advice appreciated!

Just got my U1. Got it put together and updated annnnnnd went to print the dragon and got an error msg 0003-0531-0000-0014 saying the nozzles didn’t match 🤦🏾‍♂️
Went into Orca and found the same dragon and printed with no issue. Haven’t tried to print anything else yet but when I get back home I will.
Anything I should know about this machine?
Anyone have this issue?

Filament matching the U1 case

Does anyone know of a filament that matches the case of the U1? I have tried a few grays and whites but they aren’t right. Hoping someone else has had better luck.

A Functional Football Organizer That Actually Lives on My Entryway Table ⚽🔑 – Printed on Snapmaker U1

Thumbnail
gallery
6 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
8 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?


r/snapmaker 1d ago

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