Or more accurately, is there a ZN in your R1 plus? Having upgraded my R1+ to an E3Dv6, I learned just how heavy that carriage is. It's impressive that such a mass can move as quickly as it does and produce such good prints. I've been interested in remote direct drive systems from when I first learned of a Kickstarter option many moons ago. I hadn't yet built my delta printer, a good candidate for such a drive (and have not yet built it) but figure a ZN would be a good upgrade for an R1+. Has anyone done this sort of mod? I see there's a Thingiverse adapter for the Nimble, which is promising, but I'd like to hear from someone who has completed such an upgrade.
