I just wanted to point out that a *genuine* Smoothieboard is in the same price range as a *genuine* RAMPS or Rambo.
Burnt-your-house-down not-to-spec RAMPS counterfeits from China, sold something like $20 nowadays, completely skew everybody's perception of what it actually costs to produce, test and distribute these boards.
I think Duet is probably, right now, the least expensive board that still gets produced with sufficient quality. So go for that if you really care that much about the price difference, and the Duet's features match what you want.
If you sell a board for cheaper than that, you are stealing from your customers in one way or another ... maybe producing crap boards, maybe not testing them, etc ...
And that's not even taking into account the fact that when you buy some boards, you are actually helping develop the next version, writing documentation, help users, etc ...
While for some other boards, you are just paying some random guy's salary and that's it.
That difference has to be worth something.

Your not by facts supported claim/remark is NOT helping at all but will cause damage to the 3d printer community.

But is that because of the cheap board being build so bad they start burn down your house (your words & jinx) when you even dare to look at them or because those very cheap board lowered the barrier for a significant larger group of people to start buying/building a 3D printer! And with that group came maybe the not so "experienced" users making more mistakes? Example [forums.reprap.org]Quote

* As soon as those cheap RAMPS, two years ago, started appearing, the number of reports of dead/burnt boards in the community sky-rocketed ( ask anybody who is helping on IRC on a regular basis ). This clearly shows the difference between produced-to-specs RAMPS, and these very cheap RAMPS.

really didn't think it was that important from a build point , one builder,one printer, one controller 'if I had ten controller then maybe your reasoning would make more sense to me. Yea there loads upon loads of ramps out there, but they ain't all trade seconds on the cheap either."Quote

as for the benefits of the modern 32 boards human error is reduced, feature of that is setting the driver current in software reducing the risk of burnt/shorted drivers. better fuses and so on, save setting which to restart printing if power goes out ,, nice feature of the overlord.

These are not all features exclusive to 32-bit boards. These are features of the board design, not the processor. The 32-bit boards have the advantage of being designed after the RAMPS has gone through several iterations and various needs being discovered that RAMPS couldn't support. But those features can be present on 8-bit boards if you design one to support it. The Printrboard software settings for the driver current, better fuses and so on, but is an 8-bit board.
humour aside you keep on encouraging folks to go cheap, maybe you want to mention having an CO2 extinguisher at hand "for the just in case moment your house starts burning down!!!Quote

I agree elmo and when I was writing about the fuses I was thinking Geeetech GT2560 " there still life in the 8 bit yet". dreammaker overlord got mega a 2560 at its heart. to be Honest most of that sentence comes from a desire to see those features become standard in the new boards.

one of my main concern I have with 32 bit boards design are the drivers being soldered to the boards locking me in to a driver I can never change and should I burn a driver I got the prospect of either buying a reflow oven or scraping the whole board, Personally they should have 6 driver on any modern board just to keep up with hotend designs like the diamond. aint so keen having to use of extension boards at even more cost, when designers of these boards should have anticipated, especial with reprap community teetering on the edge of multi, nozzle/colour printing becoming the norm for the last 2 years.

Boards that are manufactured in Europe or the USA and are thoroughly tested, such as the Duet 0.8.5 and the Smoothieboard, cost a lot more than boards that are manufactured in China and in some cases appear to be hardly tested at all.

all good points but still I want 6 drivers though "cant believe folks would be put off by a little extra board spaceQuote
DC42
As for putting 6 or more drivers on the board, one of the constraints is space. There needs to be room on the board to have most of the connectors around the edge (to avoid the horrible tangle you get with RAMPS and allow air to flow around the board)
like what did there am wondering about having an esp wifi and webcam into the mix for a remote shut off.Quote
