@dc42
can you point me to the github of your low cost 32 bit board . I cant seem to find it.. maybe it will be good to prototype it.

Wouldn't the Replikeo Duet 0.6 at $50 be considered pretty affordable?
Those have a very poor quality reputation. So you might end up having to buy a couple to get a good one.

Maybe there would be a space for someone to do some real testing and report on these boards, pros/cons/price with a bit of controlling for various factors that form subjective opinions.

the moment you use it to power your bed the ramps will fail somewhere along a long print with a nice puff of smoke .

This "poor reputation" of Replikeo Duet 0.6 seems to come up every once in a while, which I find interesting as no relevant facts are provided.
Any evidence to back this up?

the problem is not the atmega2650 board . those things run fine. they are made cheaper by replacing the ftdi chip with a cheaper version. the problem is the ramps board. it works fine as long as your heated bed is powered from a ssr or relay.. the moment you use it to power your bed the ramps will fail somewhere along a long print with a nice puff of smoke .

It's hard to quantify. There have been several reports on these forums of Replikeo Duet boards not working as received, and at least two of those had manufacturing faults (a missing diode in one case, and an incorrect chip in the ohther) that should have been apparent had the boards been properly tested before being shipped. Both of those were several months ago. It may be that Replikeo's QA procedures have improved since then. Also, we don't know how many people have bought Replikeo Duet boards and not had a problem with them, because it is generally when people have problems that they post here.
Testing a 3D printer control board fully is not a trivial operation. For the next generation Duet board, I am designing automated test equipment that will simulate attached stepper motors, thermistors, heaters etc. and test the board thoroughly without taking a lot of time.

I suppose some sort of database of survey results related to boards and their quality would be biased by negative reports being more forthcoming. I wonder if there is any way to encourage those happy with their product to say so.

This is my point when I asked about the Geeetech gt2560, I got a lot of "don't buy geeetech they're rubbish" no actual negative reports, and one user who said he was very happy with it.
