@Phaedrux Sorry for the late reply, you wouldn't believe how busy I've been.
Yep, I posted on E3D Bigbox forum without success but my last look for responses was 5 or 6 days ago, there may be some answers now !
I was thinking about pulling out the Duet equipment, putting RAMPS into Bigbocks in its place and selling each as separate entities. Duet and PanelDue as one and the printer as the other. I wonder which will sell first and for the most ... no, no need to wonder, the Duet will win hands down
So that's my next project, at the moment I'm ultra busy listing, packing and visiting the courier drop off shop. Once I've got rid of most of my gear I'll spend some time one the Bigbox modifications.
