Your efforts are very welcome. I was thinking about a polymer paste applied on PLA or ABS, maybe in printed grooves. Later i would apply a layer of solder on the whole issue. Unfortunately i have no experience with polymers. Could be possible from what i have heard about polymers. How conductive are those polymers? Could you blend them with metal powder? Do they degenerate fast? Are there polymeby IRBaboon - Developers
Great! I need a controls like those too. Maybe 2 servo drivers for a fourth axis and bowden extruder with feedback. This is the first reprap electronics i like. Well ok, i like the expansion header from generation 7 too and ramps has at least 5 stepper drivers. Those Pololu stepper drivers are like toys, oversold and to weak for nema 23 stepppers.
