... What was it that made you abandon the idea?

What you're desicribing sounds similar to the SkyDelta without the springs?

I plan on having the motors on the platform. This makes the design more compact too.Quote

You have to make the print head extra heavy.
That's why I think three action lines downwards (lines from print platform towards wall/floor) is a good idea. The one action line going to the roof could be made triple and attached to each corner of the triangular print platform to handle forces downwards. Three lines of equal length towards the roof would help keeping the platform flat, and would have no syncing issues since they are driven by the same motor. If this would allow us to skip the paralellogram lines downwards, that would be a nice simplification (no need for bearing at wall/anchor point).Quote

The main problem seems to be though that during extrusion the extruder normally "flattens" the extruded material and "scrapes" a bit over the stuff. This is normal but with wires this causes forces upwards and creates slop.
Absolutely, but I think there is a possibility to make the homing process much cheaper and simpler. I sketched it out on the wiki-page. It's basically just putting a detectable point on each of the lines. This procedure forces the linefeed-mechanism to be slack tolerable (which it should be anyways).Quote

They mention an automatic homing system. There are tracking solutions for PC games using web cameras and IR LEDs. That could be used to automatically calibrate and supervise the printing process.
