Pibot also has a nice looking setup and they are actually no longer in backer mode but selling.

They also have a nice full system as well. Aluminum-Magnesium alloy frame.

Quite a different product! All those external stepper driver boards... Which could be quite good, they certainly look like they have proper cooling, probably for the higher current capacity for bigger motors. There's no raspberry pi / SBC involved there, looks just like a regular uC-based system with all the bells on, I guess the "Pi" in their name is largely coincidental?

My favourite description: "no fuss, no strange"

I guess what I liked about the zeropi thing was the low cost / low feature approach, using the familiar toolchain, with the direct connection to the raspberry pi - a cheap & compact pathway to a highly effective internet-connected 3d printer system?

Looks like:
* 32-bit ARM
* Runs a port of Marlin
* Enough I/O for a single-extruder printer
* Bolts straight on top of a raspberry pi
* Only $25

Maybe worth trying as a budget replacement board for a solidoodle?

Usual riskiness/delays of kickstarter applies!
