Why would I be crazy to use a Workbee 1510, put it in a case and add a 750mm c-beam z-axis? The camera and pan/tilt head, motor and frame I estimate at 6-7kg (perhaps an overestimate). Similar to this great build by nextoone, but with a pan/tilt camera platform instead of a print head. https://openbuilds.com/attachments/2015-12-27-09-03-02-jpg.13097/
