AvidCNC-based CNC Router
I started with an AvidCNC PRO4896, and added my own servos, control system, and ATC spindle to it.
Teknic SDSK servos.
The configuration files are available on GitHub.
The tool changer uses compressed air to hold and release tools. The spindle has a constamt air purge of the main bearing to keep dust out.
A bit of overkill for this project, but I used the beautiful, Italian-made HSD ES330, a 4.5 kW, 24,000 rpm, air-cooled spindle with ATC.
This required a VFD that’s export-controlled.
