Reprap kits from Southern Alberta.


I will have kits, parts, and complete repraps for sale as soon as I am finished developing my current reprap.(hopefully by Dec) But since it is a pain getting parts here in Alberta(as I had to import almost all my stuff)once I get up and running, I am willing to cut a price break to anyone who lives in Alberta. But that requires me getting this done quick.

If you do live in alberta or want to be contacted when this stuff goes down (cause I will only have enough for about 40kits to start)

Contact me


But in the mean time, Here is info about me, my goals, status

Current Status:

Acquiring Parts / Starting to Assemble

Here is what I have so far:
  • Motors:
100 Sanyo Denki, Nema 17, Bi-Polar 6 wire stepper motors, Type: 102H5208-10U41 , 59oz-in holding torque.
File:Sanyo103H5208.pdf
with a 21 tooth MXL 1/4" wide pulley on each. Cost: PRICELESS steal!
cost me $114 bucks for the whole lot. But, shipping and import fees where $165 so it came to $278
but $278/100 = $2.78 for each motor with shipping... hmmmm. these motors sell at $15-40 on ebay... ($60 new)
However, getting the data sheet for theses was a royal pain, even at that I still need to update it.
60 T&L International Stepping motor, Bi-Polar 6 wire stepping motor, Type: 42BYG401-06A, apx 31+oz-in holding torque
with a 28 tooth mxl 1/4 brass pulley on each. Cost: Almost a Priceless steal.
little bit more pricey about $300 with import fees
$300 / 60 = $5 each with shipping, but they still have a gear head and it is the same sad story on ebay $15-40
Now data on these was even harder to find but I have some and am going to make a cad scehmatic soon
  • The Brain (aka BRAINS! or motherboard for the non-Zombie fans):
I purchase a "Seeedduino mega" when it was on sale
I think it is are great so I am planning on using it(even if it is overkill).
  • Motor Drivers:
I bought components for "EasyDrivers"
They will provide 750mAmps at 30v per phase
you can buy them from Sparkfun.com but I wanted to make my own)
  • Structure (aka Frame):
8 Hardened steel rods I salvaged from a bunch of old printers for the slides (free - 2hrs salvage)
6 3ft 5/16 galvanized Threaded rods ($3 each, got them on sale at princess auto)
apx 20+ nuts ( DANG expensive at home depot, or home hardware at +$0.26 each, buy them at totem for $0.12 instead)
100+ 1/4 USS washers (+$0.12 each, so I bought a box of a hundred at $0.05 each instead.)
USS type are NOT CONSISTENT IN THICKNESS(0.51" - 0.90"), they need presorting so they are 0.01" of eachother
  • Corners (aka the pieces that make those annoying angles):
I am cutting the intial ones out of 3/4 MDF which I will seal using wood hardener or glue-water mix.


So in essence My first reprap will actually be a repstrap/ wolfstrap since it uses wood, but hey it is cheaper than trying to buy the plastic parts since anyone I can find wants to charge a (explicit descriptive here) for them.

(The only reason this is not on a development page yet, is because I am still getting parts, taking pictures, procrastinating, assembling stuff, making excuses, writing essays)(OK, it is really cause I havent got to it yet, but I will as soon as summer semester is over (around Aug 16th))
