DuetWifi clones and support

(and tbh, I was really surprised the quality of the PRC clone was indistinguishable from original apart from crimp pins being thin PRC stuff compared to original being nicer thicker easier to crimp)
as fair as i understand, the prc clones skimp on the copper in the pcb for thermal transfer. something that you can not see by eye.

yes it is very possible the PRC pcb is 1oz, I doubt that original is more than 2oz (cause 3oz requires 10mil clearance and that's too much for both the mcu and the drivers) so not a huge difference .. the bigger issue might be the metalization of thermal vias under the drivers but I'm making PCB's in PRC factories for 20+ years and never had issue with that...
I'm more afraid they use sub-quality parts, e.g. fet's can be PRC knockoffs or mcu can be second hand.. but looking at the price of the clone, if they were skimping much the price would be much lower, these are fairly expensive clones and we know PRC sellers have puny margins. for e.g. me doing soldering myself, acquiring parts using a huge discount I have at farnell / digikey and making PCB in PRC factory cost me approx the price of the PRC clone..
anyhow I'm always encouraging ppl to buy original, there's always enough small details PRC "engineers" don't understand and do wrong + if you really want the product to thrive and progress you need to support it

What an offence seriously?!?!? Rich people can afford Without thinking, middle level buys what affordable and homeless has nothing to loose....

most if not all do 35um/1oz, without a side by side comparison its tough to spot by eye; relatively easy to measure with a micrometer as the corners with screw holes are bare FR4 giving you a reference to measure the copper thickness.
but yeah, the (for the most part*) open and welcoming community is a big pluss for duet, and not supporting cloned hardware isn't a big deal as most of the support is for the open firmware anyway, which almost doesn't care if you go DIY/LPC/whatnot.

Now my question is regarding the Duet Wifi clones out there..
Are you asking about supporting Duet HARDWARE or supporting RepRap FIRMWARE? Your comment refers to hardware yet implies firmware. Its kind of like the commenting on religion and ethnicity. One does not mutually exclude, or include the other.
I do run the LPC port on one of my printers. I also own 2 Duet 2 boards and Duex expansion boards and 2 PanelDues- by your logic, have I 'spent enough' to qualify for support to ask about the LPC installation?
I didn't port the LPC fork. I just use it. dc42 has frequently contributed to the discussion and supported and championed the effort overall. And why shouldn't he- it spreads the gospel of RRF. He offered support on the IR Sensor board when I was trying to get it working on Marlin.
People will ask me if the LPC port is 'as good as a Duet board'. I always tell them that its worth consideration as an alternative to Smoothie and Marlin. If you want a real Duet board but don't want to spend a lot of money, then get a Maestro or look for used Duet board.
There is rumor as well that there other ports in the works by others that will provide RRF 2 and 3 to more platforms.

I suppose its more targeted at the hardware side of things. Seeing some of these clone boards melt down and then people assuming it was an original Duet board is where things get sketchy, but clearly not something that is easily resolved due to the chinese way of doing things as cheap as possible.

isn't that more a problem with people assuming things than Duet and the clone wars? i for one would be looking at wiring before any potential board/clone issues if something melted. there are those among us who will run mains voltage through an tv aerial cable as part of a fixed installation..

@bearer
Fair point.
The chinese branding things as Duet, without disclaiming that it is a clone / fake. And they will use the cheapest crap components possible. But as you said, that doesn't eliminate the user error.

Duet predates the reprap movement. Anyone remember the Boxford CNC that you could stand up in mill configuration or lay flat for lathe?
