The Madison Park Vocational Machine

This machine's vocation is making other machines.

Here you'll find documentation for the mechanism and design of the machine pictured below, and rough documentation on how to build it.

mill

This implements the RCT Gantries project for axis design, and the AutomataKit project for controls.

The machine has a bed size of 410 x 820 x 40mm (16.15 x 32.30 x 1.5") - the machine itself is 740 x 1100 x 430mm, and weighs about 20kg. It fits on one 4x8' sheet of HDPE, that we cut on our shopbot with a 1/8" single-flute o-cutter. The whole thing machines in about 2.5 hours, and goes together in a few afternoons or less.

CAD and CAM

There is a rhino file for perusal under /cad in the repo. Axis are organized onto layers, and the sets of parts needed for 3D Printing and Milling the machine are present.

Jake ToDo

  • upload new .stp for other-cammers
  • link to fusion cam as is
  • fillet some more corners
  • lift psu wall if you can
  • psu holes X
  • decrease long dimension by 4mm, pull out from wall 1mm, psu is 67mm tall
  • holes are too large, decrease to 1/8" or just above

Assembly

The Tools You'll Want

  • soft hammer

  • drill, and driver (nice to have two)

  • size 34 or equiv. drill bit

  • 3.25mm or close drill bit (1/8")

  • t15 driver

  • 2.5mm hex driver

  • 4mm hex driver

  • clamps?

  • de-burring tool

  • flat head screwdriver (playing the role of crowbar)

  • Z Gantry 1st

  • bang together and screw

  • YZ Block now

  • all hardware should go on (save for motor) before the go-together - but fit up so that you understand orientation

  • socket head cap screw heads should face towards other gantry... think of where you'd like more clearance

  • X Rail, or first, or simultaneous

  • rollers go on

  • beam goes together - try to make it straight!

  • careful on the direction of the back plate - look at the wire routing bit!

  • Y Gantries / Rollers

  • hardware on, then bang on, then motors. tight screw, but manageable

  • Chassis

  • assy Y rails on sides

  • recommend hitting these edges with the deburring tool

  • floor, then sides on to floor

  • faces

  • Final Assy
