t_box_millA CNC mill constructed as a box shape
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.
