Klipper - Any benifit to the duet?

Apparently speeds up printing on 8bit boards. Anyone have thoughts about integrating with Duet?

I'm sure it could be done, but what would be the purpose? The Duets don't have the same speed and RAM limitations that 8-bit boards have. The Duets do with a single electronics board what Klipper does with two, or with one and a dedicated PC.

Thanks that's what I assumed. The other issue I see if that on most printers, it's not the CPU preventing high speed, it's the rigidity of the machine. I doubt klipper will be able to solve that.

Klipper would seem to be a clever solution to making 8bit boards more precise at higher speeds. Its a neat idea since you might already have a ramps/mega plus a raspi (with octoprint) attached.

It surprises me that Marlin didn't go this way with their 32-bit move since its easier to add a pi (plus octoprint giving you wifi capability) for £20 than to buy a 32bit board (like a re-arm or mks sbase) and then rewire your machine.

At present, it seems to be a pretty basic firmware compared to Marlin, Smoothie or RRF. But its a nice lateral thinking solution to the problem of slow 8bit boards, just use the 8bit board as a slave unit.
