Availability of 32 bit controllers

It seems to be hard to get hold of 32 bit controllers right now:
Azteeg X5 - out of stock at panucatt, matter hackers and ultibots.
Duet 0.8.5 - out of stock at filastruder and think3dprint3d.
RADDS - out of stock at reprap.me and makerfarm.
Smoothieboard - available
AZSMZ - available

Is there some reason for this, like component availability or because a new generation of boards is about to hit and the old stock is being run out? I ask part because of idle curiosity and partly because I'm considering what 32 bit controller to use on my Eclips3D.

I can only comment on the Duet board....
I have an order in for a Duet 0.8.5.from Filastruder, that should be arriving in a small batch in the next few days. I was told just before I ordered that they also had another batch coming in after that.

Duet series does have a new board in development called the DuetNG (NextGeneration) but in the announcement it was said the 0.8.5 version would also remain available.

MKS SBASE Smoothieboard clone is also available. It's cheaper than the Smoothieboard (~$80) and has five stepper drivers, but comes with the standard Chinese-clone quality control.

Gen7 appears to be available.

I can only speak to Duet, the limitation is supply-side - the UK manufacturer that T3P3 is working with can only crank them out so quickly.

And this is how the Chinese are.getting the Change to take a big peace of the marked. All that cant deliver now should not complain later.

P3steel DXL, with Due/RADDS/Raps128 dual Wade's extruder

... I'm located in Germany and in contact with the developers of the RADDS-board, so no problem to get them (have got some 10 of them together with the Dues - 7 in use, 3 spare)

AFAIK they ordered/built a new batch, which is actually been delivered to some of the resellers ...

So whats the difference with the Duet's you see on ebay quite cheap and the 0.8.5 version?
Also I think the numbering of this might put some people off, they may be waiting for the 1.0.0 version....
it sounds a little unfinished despite how well it might work.

Unlikely. Controllers are pretty much the same since years now. Look at the good old Gen3, it does pretty much the same as recent controllers: drive 4 steppers and 2 heaters with an affordable MCU. 32-bit is less the result of an urgent demand, more the result of the availability of such chips.

These days it's also clear that selling printer parts and/or kits isn't a get-rich-quick recipe. With Solidoodle, RepRapPro, eMakershop, others closing, much of the enthusiasm is gone.

... I've changed for the 32bit controllers for speed reasons - this will be different, if you don't have speed- or timing issues with the older types, but 16/20kHz compared to 90/200kHz is a pretty big leap forward.

... so, if all the people have learned this lession ... maybe we can rethink the basic idea around "...wealth without money"

As far as the Duet 0.8.5 is concerned, I think T3P3 has been caught out by demand ramping up much faster than expected. Some high-end kit manufacturers and manufacturers of professional 3D printers have adopted the Duet or are in the process of doing so. Stocks are definitely not being run down in anticipation of the Duet NG, which is still a few months away. The latest I heard was that new stock is expected in a couple of weeks or so.
