Summary

3D printer which will print its own body (I hope)

Thought's:
Print onto ABP with stepper as the Z axis, and canter the Y axis at 45deg which may allow very long prints. (STL's will have to be rotated to 45deg in skeinforge)

Objective:
A bot that can print bigger than itself.

Update 25 Sept 2011, Bot final dimensions 420mm Long x 210mm High x 198mm wide - Print Size 50mm High 215mm Wide.... errr and very long (hopefully)

Instructions

HAH none yet, first stage is get my mk5 going again, work halted till then.

Attached is picture of the mk1, trying to export the simpler mk3 files at the moment but Alibre not behaving. (possibly im a bit drunk),

Update 25 Sept 2011- Still drunk (now MK7 looking good and has a name)

Sorted parallelism problems whent to rack an pinion system. Sorted slop on rack and pinion by positive tension between pinion and rack. XY axis now work well, although noisy. Also need adjustable mechanical end stop Y axis to stop print head burrying into print bed when motor turns off.

Belt no good, Size wrong 40mm former pipe ended up with belt wider than expected and thus tension system failed. Replacement of belt requires removal of front panel and hole belt system, also leveling currently wrong it needs tripod adjustment not just left and right but the front as well. Current design missing racers ether side of belt driven side to support long prints using printed support material.

Will try to sort, may even get the tool head channge to work as left space on right side of box for additional heads and the stepper is not part of the tool head, but thats for the future.
