Building A DIY Prusa I3 MK2
Hello,
I have ordered a Prusa is MK2 Kit but would also like to build a second printer on my own while I am waiting on my factory i3 to be delivered. I have found just about all the info I need except a few things. Here's what I need to find out:
What is the length of the M10 Threaded Rods used on the Y-Axis?
What is the length of the M8 Threaded Rods used on the Y-Axis?
Where can I buy a 623 housing used for the Y-Axis smooth idler?
What is the length on the 3 sets of 8mm smooth rods ???? I am seeing conflicting info not sure what 3 lengths to get,
if anybody can help me out, I would be much obliged. Thanks.

Threaded rods:
4 pcs M8*200mm
2 pcs M10*350mm
The hex-nuts are 0,5d type. Washers are standard size.
8mm linear guiding rods:
2 pcs 320mm
2 pcs 330mm
2 pcs 370mm
Wait for a verification from somebody else before taking this as fact!!!

...but would also like to build a second printer on my own while I am waiting on my factory i3 to be delivered.
main problem (and, beside the rambo board, most expensive part) will be that you need to get an MK42 heat bed and the required inductive sensor (called "pinda" here), these parts are only available for customers as spare parts after your account has been unlocked by the customer service.
if you want to stick with the original design (because you've asked for the exact length of the rods), you'll then need the frame and the y-carriage as well from prusa.
all other parts and even the rambo could be ordered somewhere else.
dem inscheniör is' nix zu schwör...

FWIW I will have some MK42 beds in a week or less. I am having about 20 printed and setup. I might be able to part with one or two as I'm having them built for another project. PINDA projectors are just induction injectors. Which means they respond to ferrous material. You don't even need to find a exact PINDA injector but rather something like this should, in theory, work! http://www.aliexpress.com/item/10pcs-NJK-5002C-NPN-NO-10mm-Hall-Effect-Sensor-Proximity-Switch-DC-6-36V-Inductive-Proximity/32701042659.html?spm=2114.13010208.99999999.264.79631H

Thank you everyone for the help. I sincerely appreciate the time you guys took to help me out. Very much appreciated.

The induction probes do not require a ferrous metal; the current probe points are copper.
Unfortunately, the probes need to work from a 5V supply, so you will need to find something other than those linked above.

Oh, thank you for that bit of information! I would have been beating my head over why it probably wouldn't have worked!
Re: Building A DIY Prusa I3 MK2
If you are in the UK I can recommend Ooznest, I got their own brand frame, the rods and a power supply from there and then ordered the Mk2 upgrade kit for the other bits from Prusa. The only place I could find with the RAMbo in stock was Ultimaker.
