3D chocolate printer made from LEGO

Step 9 Build a lego gantry

I can't remember all the details, but it's pretty simple. i used rack and pinions for the X and Y axis gantries.

there are lots of ways to do this. You really want z axis too. i hacked the Z axis by using a layer by layer increment ratchet that was mechanical. given the memory limits of the PCX bricks, one layer was about all you could program before having to upload a new layer code anyway.

isn't the frame work that znaps stuff?, iv'e got some somewhere... im planning on using an old hp printer and exchanging the ink for a feeding chamber for the stuff that will print out the 3d model, not sure what yet maybe sugar or something...

worth the try, we all have old printers sitting there doing nothing,
but i worry about the programing?!
any idea?? even to be used in CNC???

Fab! Has anyone got actual plans (including a Lego parts list) to build this?
