Profile

  • Name: David
  • Country: Canada
  • Schooling: Currently attending University
  • Field of Study: Combined Computer Science and Business Management

My Goals:

  • To build a RepStrap/CNC platform that has quickly Interchangeable/Multiple Tool-heads.
  • To contribute to the RepRap community, via wiki, and hopefully The sale of RepRaps kits/parts to help this community grow.
  • Learn More than what I already know.
  • To help in the development of a basic sewing machine / Embroidery attachment for the RepRap.


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 me $278/100 = $2.78 for each motor with shipping
However, getting the data sheet for theses was a royal pain, even at that I still needed 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.
$300 / 60 = $5 each with shipping, but they still have a gear head and it is the same sad story on ebay $15-40
the motors sound grainy when turned
  • The Brains:
Ramps 1.4, Melzi, Generation_6_Electronics
  • Motor Drivers:
Ended up getting some polulu motor drivers when they went on sale for my first reprap
A4988 Polulu drivers
I bought components for "EasyDrivers"
for when I get around to playing with making circuit boards
They will provide 750mAmps at 30v per phase
  • Structure (aka Frame):
8 Hardened steel rods I salvaged from a bunch of old printers for the slides
6 3ft 5/16 galvanized Threaded rods
5/16 nuts
5/16 external tooth washers
100+ 1/4 USS washers
USS type are NOT CONSISTENT IN THICKNESS(0.51" - 0.90"), they need presorting so they are 0.01" of eachother
^ know what, forget presorting, as long as the nuts are in the right spot, the washers can be as big as they want to be.
