Looks to be a pin-for-pin-compatible drop-in replacement!

I'm sure ednisely will chime in soon enough -- but basically, it uses a new high-speed CPU that can handle higher interrupt rates and more software features. Things like full mesh leveling with interpolation, ultra-high step rates (not for high speed, but for running 1/32 drivers at normal speed), and a non-laggy LCD display.

Almost a drop-in replacement---it has a microSD card slot that you either keep permanently occupied, permanently empty, or cut an access hole for.

Pfft: ya learn something new every day around here!

I like the 32-bit-ness, but know nothing about the Marlin4Due firmware branch.

Looks like a good way to get sliced on the leading edge …

Pfft, Ed that was a weak-ass reply, I figured you'd at least back up some additional benefits of 32-vs-8-bit for Farr0wn3d.

Wonder if I can get MG to buy me one so I can play with new firmware :lol: worked for the drop-in E3D upgrade (which nobody but me cared about apparently).

It certainly enables feature creep in a big way!

I'd vastly prefer something like Machinekit (http://www.machinekit.io/) or its direct ancestor LinuxCNC (http://linuxcnc.org/), because they're built on an industrial CNC base. Both let you write actual G-Code programs with variables & computations, plus drive the affair from an external program (not a G-Code stream); if those features show up in Marlin4due, it'd be wonderful.

That's basically the difference between a real CNC controller and an Arduino stuffed with a G-Code interpreter + quasi-real-time control. Nothing wrong with Arduinos, but 3D printers have long outgrown their capabilities and IMO it's a Bad Idea to keep building on that foundation.

Selah.
