A CNC mill in the general shape of a box

A new mill based on the lessons learn from the t_strap_mill.

Overall design ideas/goals

  • Use OpenSCAD to create the assemblies inside the computer possibly avoiding some designs flaws prior to printing and fitting the parts.
  • Parametric design when possible.
  • Use the OpenSCAD data to create the Bill of Materials, probably using ThingDoc.
  • To be designed with a moving Y axis.
  • Replace the threaded rods as structural components with MDF sheets, both are annoying to cut, but it is easier to create rigid structures with MDF.
  • Use of rectangular cut MDF panels, no fancy curved parts.
  • To be created as a box with the front side open.
  • Should remain small enough to install inside a Ikea Stuva cabinet for additional noise reduction.
  • Reuse parts from the t_srap_mill when possible, probably only the motor mounts.
  • Reuse the "expensive" hardened steel rods (and other vitamins), but keeping in mind that upgrading steel diameters should be relatively easy.

Possible design issues

  • Resonance, the use of large MDF panels could turn the mill into a "speaker", on the other hand semi enclosing the noisy spindle and milling action may dampen some noises.
  • Wood, The switch from a plastics and metal construction to a wood based design may cause issues with moisture expansion, however other mill and 3D printer designs successfully used wood.
