What I was asking. not too well, is what does this "cura" run on?, the printer or some computer I need to buy to complete the data chain between openscad and the printer? Or can I run it on this linux box? Then export that gcode over cat5 to the printer. > You can put the gcode file on an sd card and plug it into the printer > or I use repetier host as a gui that draws pretty pictures as it > streams the gcode to the printer.

I figure they are, much of what code generators produce that runs to several gigs per part, can also be produced by a 100 line gcode file using loops. The diff at the part level isn't, but one can be gigabytes where the other might be 4000 characters. Your own optical encoder wheel is a good example, I've further modified it and used it, several tines now.
