Yeahhhhhh, i'm not really sure it's exactly suitable for conversion, i was thinking it might be a good basis for an 'everything' machine.
It comes with probe and although i have not a clue how to use it might be be possible to use it for reverse engineering some things.
The current 'arm' with the probe would certainly be strong enough to mount a extruder on, maybe the rails etc could be increase in size or maybe just use the base as a table to build a gantry style router off?
