TL;DR: I've been building iDither.com, a tool for getting better full-color prints from the Snapmaker U1. It predicts how textured 3D models will actually look when printed using the limited number of toolheads. I’m looking for other U1 owners to help test generated prints and compare the real results against the website’s predicted preview, since I only have one printer and each test takes hours.

How it works:
You upload a textured GLB, choose the filaments you actually have, and iDither analyzes the model to determine how those filaments can be mixed into virtual colors. It then shows a predicted print preview so you can see what the model should look like with those specific filaments before committing hours of printer time. It can also generate a 3MF for printing, using all of the available 60 virtual colors.

The goal is to solve a pretty annoying problem: what looks great in the original textured model isn't necessarily achievable with four physical filament colors. Choosing the right filament combination - and knowing what the resulting colors will actually look like - is difficult and can waste a lot of filament and print time.

I need help validating it against real prints.

I only have one Snapmaker U1, and these tests take a long time to print, so there's no realistic way for me to test every filament combination, model, and setting myself.

If anyone here has a U1 and is willing to help, I'd love to have people:

• Run models through iDither
• Print the generated result
• Compare the actual print to the website's Predicted Print Preview
• Send photos and let me know where the prediction is accurate or wrong

The more real-world data we can collect, the better I can calibrate the prediction system for everyone.

If you're interested in helping test, please comment or DM me. Even one test print would be useful.

This isn’t all of them.

Just printing a 5mm thick rectangle with 0.08mm layers on Snapmaker U1. 6mm brim. Polymaker PLA.
I heard the print head grinding on part of the model and I stopped it. I did bed level calibration before the print started.

Trying it out with only the head first

He’s adamant to ruin my prints.

✅Warm
✅Butt Vibrations
✅Perch

Not sure what to do…

Surprisingly bad print failure. AI didn’t detect anything wrong.

Migrated from Bambu A1 over to Snapmaker U1. Never used textured build plate. Just throw it away?

Bambu AMS TPU is the name of the filament.
It’s completely dry, and I tried it with and without AMS.

I convinced my wife to get my first little set of Milwaukee tools after my Hyper Tough drill finally died after over 10 years.
I lost my drill for a whole week, and I looked everywhere.
Turns out I left it outside during a very rainy week, and it finally wouldn’t turn on with a full battery!

Well, today the Milwaukees arrived…and my Hyper Tough came back to life!! Not sure if my wife has to know. 🤔

I am not sure what I'm doing wrong. Plz help.

I never unwound it, it was like this from factory. 😒

The lock sometimes prevents my door from closing at all if the door is still left open after 30 seconds.
After 30 seconds the lock is initiated whether the door is open or not.
I have a door position sensor on the door so it should be possible to only lock when the door is detected as closed?

I am also willing to do some “processing” if a filament that looks like brushed aluminum doesn’t exist.
