Using an inkjet print head on a CnC device. Answered

Ive had a bright idea that in short requires me to mount an inkject on a 3d printer of sorts for printing on a complex shape. Ive only done some cursory searching, but not found a "here is how to drive the inkjet" or "We recommend this model" for my purposes. Im toying with the idea of just ripping up a standard printer and seeing how well I can reconfigure that to my purposes, but I don't think it will do quite what I am looking for (in addition to the X and Y axis, there will need to be a Z, and in the eventual build probably a sensing mechanism to detect the shape it is printing on (im imagining a projected grid, but that is a ways down the line)). I'm going to have to learn a good bit of methodology to write the needed code, which is going to be a blast. But the starting point will be just the x & y coordinates and a DIY mounting of the print head.

Any advice out there?

I may build it out eventually on a raspberry pi but I haven't gotten that far as getting the mechanics working by feeding input to an Arduino for an almost etch a sketch mode will be my starting point.
