Re: E3D firmware update for Printrboard
You'll need to spend some time looking over things as that firmware is not set up for dual extrusion. Should just be a simple matter of Un commenting the appropriate lines to enable the second extruder. Maybe have to double check some pin assignments and verify that they are correct for the Z axis issue. I'll spend some time digging for a preconfigured version for your machine. Being able to flash successfully is the hard part, good job.
