I've been out of this thread for a long time now. I can say that I've given up on the CubePro. It is not worth the time and effort to get good prints. The early folks and Simplify3D made the CubePro a usable machine for a while, but constant filament errors, lousy bed adhesion, and very very fragile hot-ends have cost us thousands in lost time and replacement parts.
I've bought a RAMPS board and a Chimera(knock-off) hot end (total of $100) in parts and I'm in the process of rebuilding this printer.
So far, it has been relatively painless. I've got the motion control working well so far. By next week, I should have the thermal stuff in and working.
My advice to anyone STILL trying to make these #$%# devices work, think about gutting the printer. Simplify3D is vastly superior to the stock software, but there are just too many gaping holes and workarounds STILL left to do to get good prints.
If all goes well, i'll post what I've done.
