@FreeCAD I'm working this #FreeCADFriday on a new open licensed CNC mill design. Helpful critique on how I'm using #FreeCAD and the machine design itself is very welcome!

I started a thread on Maker Forums about an open hardware design for a home shop CNC mill that is designed to cut steel. It's called the Chela Mill. Many details are still TBD so if you're experienced with (or interested in) machine tool design then I'd love to see you weigh in, here or in the forum.

One step closer to using a FOSS CNC controller to make atoms move.

I'm having a heck of a time finding a spindle and VFD combination with enough torque at steel cutting speeds (600 to 1200RPM), has a power drawbar for ATC, and has a taper like a BT30 or TTS. I aim to keep the total Chela mill material costs around $5k so a $4k spindle like CNC Depot's FM series, while excellent for many projects, won't work here:

In quite moments during the holiday I started an open design for a CNC mill that:

- Fits within a 1200mm x 1200mm x 600mm footprint (~4' x 4' x 2')
- Has a cutting envelope of 700mm x 300mm x 200mm XYZ (~2.3' x 1' x 0.6')
- Easily cuts mild steel and can take light cuts on stainless
- Uses a fully FOSS workflow including FreeCAD and LinuxCNC
- Avoids vendor lock-in
- Works with single phase 220

Ok, I started a build thread for a DIY CNC mill over on Maker Forums:
