Second prototype gets some guts
I've got the electronics mounted up and the motors installed. This is much more of a working environment than a prototyping environment, so all the baords have been hived off into a little plastic box. It has a lid, and maybe one day that'll fit on. Meanwhiles, I fear the spaghetti will proliferate a bit. Thought you might want to see this morning's progress:
Yes, I know we planned to mount the little boards on the parts that they control. However, I need equipment that will survive the airline baggage handling system so something a little more robust is needed.
There have been questions about how the Polymorph and No. 8 wire are used to hold on the Mk 2a head, so here's a detail view with the background shaded out to clarify things. The long machine screws have a nut on them underneath the Polymorph, which is in turn cored with single strands of No. 8 galvanised fencing wire:
A wire end can be seen sticking out lower right. The saddles provide a handy anchor for hose clamps, and are contoured with a lip to help keep the clamp in place. The black heater power cable snakes through the view.
Vik :v)

I've pretty much arrived at the same conclusion. That way all the electronics can go in one box with a cooling fan or two and maybe even the power supply.
In fact, why not put the whole shebang in a minitower? Hmmm...
I can see why Sai wants to take it apart. :-D

It should be interesting to see if they are going to let you on a plane with all that suspicious electrical stuff and a sack of white CAPA granules. :-D
Fantastic. That really looks the mad-scientist part - perhaps you should add flashing lights and a skull somewhere.
How about a Jacob's ladder? Bzzzt-bzzt-zzzzzt! :) Also, I highly recommend blinking LEDs. They give the workshop, ahem, -lab- an atmosphere of cryptically monitored technology.
BTW, that closeup of the extruder really shows how RepRaps can be built much more lightly than subtractive CNC machines. I also like how the extruder is static. That way, the tallest component is not swaying back and forth as the machine works.
Now as for the skull suggestion, how about a brain, a Brain... Aaa -BRAAAIN-!! Bzzzt-zzt-bzzzt!
