Well the Hackerspace Frankencake 3dprinter is now working .Its only limitations are 100mm x 100mm build platform and it can only run at 50mm per second as the makerbot stepper motors are really weak.
It still needs a cooling fan for the build area but I figure that some one else can contribute that piece of engineering.
The original makerbot PSU isnt strong enough to power the machine so I need some one with some experience to convert 2 of the high current PSU's at the space. ( one for the CCHS Mendel and one for the Frankencake).
If some one with some digital artwork experience would like to design a 3d printable Frankencake name plate and logo that would be fantastic.

Hello John
Good to hear! I'm quite looking forward to working with it. I'm happy to
look into creating the fan, but I would need to
a) know whether the fan is to cool the plastic on the bed to make it
solidify faster, or whether it is to aim at the top of the hot-end to
cool that part down, and
b) check how to best mount it.
Cheers,
Holger
PS: Your Frankencake puts my Frankenmax to shame ;)
PPS: No, I don't have experience with digital artwork :(

Someone suggested just hooking up one hard drive to draw some power
should work. Plus of course you'd need to short PSON and Ground somehow.
Does anyone use computer PSUs on their printers - or is that what Holger is
talking about in the first sentence? I've got one at home that I use for
that odd 12V/5V source in a pinch. Cheaper than the $99 listed below and
easy enough to work with if you can get some Molex connectors.

I payed $35 for my pc supply and it has 2 completely separate 12v rails
good for 32amps - purchased from weekend computer swapmeet, google swapmeet
and look for technology markets for areas, dates and times

I just bought a PC PSU with 40A 12v and I'm not happy with that it still drops to 11.5 volts with about 13Amps hanging off it ( the Frankencake) I think I am going to go with the 13.8v one Holger suggested

Where are you measuring the voltage? A drop of 500millivolt at 13 amps can be caused by a 38 milliohm lead ... and you certainly can achieve that with the Jaycar unit as well ... unless you use a Kelvin 4 wire connection which allows for the resistive drops to be compensated.

I'm measuring at the supply itself. I'm not to worried , it's easier to up the voltage . Everything works better in these printers with more volts. the heaters warm up a bit quicker. I am running one of my printers at home with 17 volts.
the steppers have way more power and thus skipping steps is less of a problem.

Just remember if you have the diod removed on the ramps and are running
higher than 12v then forget using you machine stand alone as you need to
power the arduino separately else you are going to need 2 power sources

I am planing to run the spaces Frankencake on 12v only so it can be stand alone when we add the new controller board. on my one I will add a 12v reg to run the arduino.
