I have seen clones without the proper attribution.

So sad

Do you think it's 'cause they try to pass off as genuine or they just couldn't bother the modify the silkscreen?

Don't know if any of the clone sellers pay any $$$ to the duet.

They don't.

Expected so, but hoped there are at least some

the latter; there isn't any incentive and what you see isn't always what you get either, so passing it off as genuine comes down to the pictures, not the product

not to mention few (if any?) clones are using 2oz copper

Yeah, completely forgot about that, I kind assume most multilayer (more than 2 layers) boards are 1oz as I design those didn't know original is 2oz. I have 2 clones here, will run them trough same paces and test with thermal camera, will be interesting to see

@bearer weird, the two clones I have, one is from fystech or something like that and other from big tree tech and two originals one from e3d and other from some usa seller I think matterhacker but I get them all mixed up (brother clicked on the first usa seller he found on duet site and got me one, iirc it came with matterhacker stickers + duet stickers) ... both clones look close to originals but silk states it's "based on".. but of course, probbly there are cheaper clones too

Have you considered releasing kicad files already with the 'Based on ...' silkscreen?

This will avoid confusion from lazy or uninformed cloners and is still a valid OSH.

That's exactly what we did for the 1.03 and 1.04 PCB revisions.

Anyhow, yet to see a clone that does not say it's a clone.

A clone that doesn't say it's a clone is a counterfeit. A clone that says it's a clone is a lawful reproduction which is one of the goals of OSH.

One problem is that the names Duet (an OSH design) and Duet3D (a brand) are too close and easy to confuse.

What is Aliexpress's policy about counterfeits? Do they take them down.

That's good. Have you seen 1.03 and 1.04 clones that didn't have the attribution text?

If so, it's malicious.

Some decades ago I made some soldering iron driver for 2 type of 4 wire soldering iron handles (the RTD ones like hakko and clones and TC ones like solomon and clones, but 4 wire only, so heater and sensor separate - I still run my weller using it and use it much more than my pace or hakko's) and I seen that same driver being sold on the aliexpress. I contacted them mostly as a joke (as I push all the work I can with unlicence but that project was not marked with any licence at all at the time so it's gray area) and never got any response from them, neither from aliexpress nor from the seller's ( 2 of them were selling it). The board was not for sale for long (maybe 6 months tops) as better driver became available that supported both 2wire, 3wire and 4wire handles, they ripped off some guy from Romania that designed that one. So in my experience, AliExpress ignores you if you contact them as private person about counterfitting and IP theft. Now, probably, if you send them a letter from layer with proper format and wording things would be different.

I just did a quick search on Aliexpress and couldn't find a single duet wifi that is represented as a genuine or by Duet3D. The ones I found actually said 'cloned' and the back of the board had the 'based on ...' text in accordance with the OSH license Duet3D chose to use.

it is in-line with my experience too
