Introduction
SeeMeCNC H-1 design is based on the Huxley. Primarily to produce as many parts as possible with injection molded parts.
Notable difference in the H-1 is that it's built primarily for using standard SAE hardware and English units. All of this is supposed to make the sourcing parts and building components easier in the U.S.A.
Uses 1/4-20 threaded rods for the main frame and the Z axis lead screw, and NEMA 11 thru 17 sized Stepper Motors.
H-1 Build Instructions

Supplies
All of the hardware should be readily available at local hardware stores. The plastic parts can be purchased from SeeMeCNC.com or from someone who has printed the parts from the CAD files.
Some parts, like the PTFE tubing and electronics, have come from sources other than local stores.
(soon to be uploaded)
Dimensions
Approximate Build envelope is 6" X 7" X 4". Although, enlarging the machine slightly involves only replacing the threaded rod sections
Injection Molded Parts
Printed parts
Need sources
Electronics
SeeMeCNC is using mach3/EMC2 configurations on their prototype machines. Any other type controller electronics could work, such as arduino, sanguinolulu, ultimaker RAMPS etc...
Do not buy their electronics if you want to run an arduino based setup, just buy their hardware.
Steppers
Standard NEMA 11 OR NEMA17 steppers.
Extruder
"Steve's Extruder" is a gear-driven, dual driven pinch feed roller design. It uses either a NEMA 11 or NEMA 17 stepper motor. The hot-end uses two 6.8 Ohm resistors, and a thermistor for temperature control. The gear driven unit has a gear reduction ratio of appx. 6.5:1.
Timing belt
Metric T-5 timing belt
Bearings
Plastic Acetal molded bearings or 1/8" x 3/8" steel roller bearings
Nuts and bolts
All hardware is standard inch units. 1/4-20 Threaded Rod 1/4 Drill Rod (for linear rod) 5-40 nuts/bolts for sub assembly of linear bearing plates
