Overview
Esp cnc is an open-source printed circuit board by funkBuild, from the funkBuild/esp-cnc repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 33 parts on 119 nets, routed with 158 tracks and 0 vias.
It is built around the ESP32-WROOM-32, TL072 and 74HC595, with the PCM5102APW among its other parts. Its parts include 12 ICs, 7 resistors, 7 connectors, 6 capacitors and 1 diode. It belongs with the robots and motor control boards and the ESP32 boards of this library.

-
position callback called on a timer. Motion handlers register with it for each axis
-
Convert stepper to use position as mm instead of steps
-
Brake outputs for each axis

spindle speed variation. M138 / M139 https://www.haascnc.com/service/codes-settings.type=mcode.machine=mill.value=M138.html
Haas - 4th axis - M11 unclamp, M10 clamp 5th axis - M13 unclamp, M12 clamp
- Properly calculate feed rate on 3 axis (GRBL is wrong??)
- Calculate 5 axis feed rate using distance to axis of rotation
- Support inverse time feed rate

Questions
What parts does the Esp cnc use?
33 parts, built around the ESP32-WROOM-32, TL072, 74HC595 and PCM5102APW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Esp cnc KiCad files?
From the funkBuild/esp-cnc repository on GitHub, at the commit this page was made from: the board is pcb/pcb/pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp cnc design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
