Having made the proposition, i guess i'm an obvious candidate for testing
I have a single extruder Orca .03 and an Replicator 2X.
The Orca i have to repair first, its got a congested and probably damaged nozzle. And the nozzle that fits these aren't made anymore. So i got a J-type ready for it but i will probably have to modify the X carriage to make it fit. While doing that i'm probably going to look to make it dual extruder (or more) ready.
But i can already test anything you guys have with the Replicator 2X. If convenient, i also have a small virtualisation farm going at home. So i could run a local version of the server for testing purposes. It's a ProxMox, and can run OpenVZ or QEMU images.
Just let me know what i can do.
