Is this board Genuine or Clone?!
-
Ladies and gents,
I need advice on this.
The other week I've bought a haul of quality 3D printing-related things, all "real deal" genuine parts like Openbuilds motion parts, Meanwell PSU's, E3D V6's/Titans, Mini and Einsy RAMBOs, Smoothieboard... and Duet WiFI with Duex5.
He even had some paperwork for some bits and pieces (from Ooznest, Ultimachine, E3D etc) but not for everything including Duet bits.
He claimed everything is genuine but I'm a little bit unsure about Duet.
I don't have my Duet anymore so have nothing to compare it with apart from 1-2year old memories of it...
What raised my suspicion was those blue heatsinks that clones come with (although he had a box full with random heatsinks so might have been added later one).
How can I tell it's real and not fake?!
Thanks.Kris

Pictures?

@kr15_uk pictures, and the serial number will help.

Aside from photos and a serial no., there are some other hints that may indicate you have a clone:
-
some clones are marked as such on the back side with a modified silk screen print. If that's the case it should be clear. Unfortunately, there are too many clones that don't honor this part of the license.
-
some clones are much lighter than the originals due to using a PCB with less copper. If you have the same revision original duet board at hand, kitchen scales might give the clone away.
-
some clones do not adhere to the colors of the status LEDs for VIN/USB/heating etc. A difference in LED colors might give the clone away.
There are some other indicators like clones also using cloned molex connectors which can have an off color, the screw terminals being different, etc.

My apologies. Please see pictures attached.
Unfortunately, Duet WiFi turns out to be a Clone board (sigh)...
But Duex5 seems promising though, can someone please confirm?!
Thanks.Kris

@kr15_uk the Wi-Fi is a clone. The duex might be the real deal

Duex5 looks similar to my genuine one, except for the heatsinks on the stepper drivers. Do these actually make any difference to? I thought the stepper drivers conducted very little heat through their plastic tops, mostly through their bases into the PCB, and had read that you get better cooling by mounting the heatsinks on the other side of the PCB!

@kr15_uk The Duex5 is genuine. Clones of that tend to be older versions without our more recent changes.

Precisely so! The stepper drivers have a large metal pad on the bottom to conduct heat away through the PCB. That's also why there are all those small holes underneath each stepper driver - they're called "thermal vias" and serve to increase the surface area of the connection between the chip's power dissipation pad and the copper of the PCB.
Putting heat sinks on top of the drivers is quite pointless if the PCB is correctly designed (which it is in the Duet3D hardware).
Putting them on the bottom might help with the tiny little plug in stepper driver boards used on other hardware, but compared to the size of the PCB on the Duet/Duex boards, I wouldn't imagine they would make any significant difference.
