Fysetc pays to Duet3D and the dc42 fork of RepRap?

[Wyvern]

The Duet isn't cheap and I can see where a clone may be tempting, but, If you are paying $100 already, just fork over the other $60 and get a genuine part that has been tried and tested.

I've been burnt on clones before, and an expensive printer that extrudes expensive material and can easily destroy it'self in a matter of seconds and can start on fire isn't something to cheap out on.

[dc42]

One thing we don't know about the clones is whether they use 2oz copper for the top and bottom of the PCB as we do, or whether they use the cheaper and more standard 1oz copper. If they are using 1oz then the stepper driver and MOSFET heat sinking won't be as good, and the bed heater maximum current should be de-rated.

Genuine Duets sold by Duet3D and our distributors come with a 6 month warranty and include a connector pack.

@dc42 It probably varies depending on the clone manufacturer. Not all of the Chinese manufacturers are in a race to the bottom - a friend of mine goes to China for Apple to handle hardware QA, and nobody seems to call Apple hardware cheap and shoddy. But then, when you want quality from Chinese sources, it isn't dirt cheap anymore, and many of the people buying stuff on AliExpress are just looking for the cheapest possible price, so they get rock bottom quality for rock bottom price.

My original question was more just idle curiousity about whether Fysetc was actually sending some money back to you guys.

The Duet WiFi is far too much hardware for my little Ender 3, a Duet Maestro is a better fit. Someone is coming out with a drop in replacement board on the Ender 3, which is basically a Smoothieboard with TMC2208s, 4 layer 2oz copper/layer PCB, properly spec'd connectors, etc... which will cost about the same as a Duet Maestro, so I've been looking at the Duet Maestro vs future Paquette Smoothieboard. The more basic decision for me is RRF vs Marlin and not Chinese clone vs authentic Duet, or Duet 2 Wifi vs Duet Maestro.

Marlin seems to have large pool of committers, big feature set and the predictably uneven quality, while the dc42 RRF seems to have a very small set of committers and less features, but a better reputation for quality. I still think it makes sense to have a way to collect donations to support ongoing development, and not depend solely on hardware sales.

@dc42 do you have patreon?
I had opportunity to compare both clone and original DUET Wifi boards
There are many many differences starting from components to assembly quality and even traces....
Clones are much much more likely to be shortened and burned.
Also there are missing many safety features, that original DUET board has, so I dont know if 20USD is worth burning your house :?

Are there any particular features of Marlin that you want, that RRF doesn't support?

Don't forget that RRF has some really major features that Marlin lacks: boot time/run time (instead of compile time) configuration, web interface, macros, flexible tool definition and management, additional axis support. Also, many features that Marlin has specific code to support can be implemented in RRF using macros and other standard features.

@dc42 I'm an unsophisticated hobbyist user and not focused on individual features, so much as general attributes:

1. Stability.
2. Usability - ABL using BLTouch, a good web GUI, good tools for monitoring printer status
3. Configurability - I had to edit header files and rebuild kernels in the 90's, but that's a 1990's workflow - hopefully it shouldn't need to be done very often in 2019
4. Safety - not interested in a long running print turning into a potential fire hazard due to poor thermal design on the controller board, shabby component specifications, or poor error handling in the software cascading into a catastrophic hardware failure.
5. Print speed and quality - I don't want processor speed and outdated algorithms to be the bottleneck in getting good prints at 100-150 mm/s print speeds.
6. Quiet - the Trinamic drivers seem to be the ticket

@sychan and every one of those items you have listed are in RRF What features does Marlin have the RRF Doesn't?

@sychan

you say apple products are not cheap and nasty, i disagree, they are some of the worst products on the planet, the only thing apple is good at is marketing and the sheeple lap it up.

if you disagree with me about apple providing terrible quality i suggest you look up a repair channel on youtube Louis Rossman

Go watch a few of his video's then come back and tell me that apple dont sell cr*p

apple are also proven to lie to their customers... all facts so please dont use apple as an example of quality...

[A Former User]

the real worm in the apple is planned obsolescence and the vendor lock-in that has a service department whose 1. priority is to sell you a new device.

anyways, back on topic; Fysetc clones are 1oz/35um copper top and bottom (or they were a while back), no idea about the other issues mentioned.

I'm not sure why this 7 1/2 month old post has been resurrected but I doubt that having a pop at @sychan is having much effect - given that he only ever made 6 posts and was last online on 28th February 2019.

[A Former User]

@deckingman

who was having a pop ?

I was merely pointing out a fact, that in no way can apple be held up as a shining light of quality...

[deckingman]

@calvinx For sure I agree that Apple products may not be the shining light of quality but why wait more than 7 months to reply to a post that was made on 12th January, on a 3D printing forum, by a user who last visited these forums on 28th Feb to make that point? I'm not trying to start an argument but it just seems a strange thing to do.

You can donate yourself to dev. team

Are you sure? How?

Regarding Fysetc, they started to have their own PCB layouts such as the small footprint PanelDue 5i. Anybody knows if those layouts are open source?

[T3P3Tony]

@zapta as far as i can tell nothing they do is opensource, although obviously copies from us.

[zapta]

@t3p3tony, now I get the trade war.
