Dave, I only run Linux on Pi, Raspberry and the PC that is connected to the MESA 7i92H. To get LinuxCNC onto the Pi4 I have this file in the same desktop folder as the Balena Etcher on a WIN-10 Laptop. 2020-09-08-linuxcnc-2.8.0-pi4.img came from the ZIP file I downloaded. Select the SD card location, click FLASH and when done insert into Pi4 which is connected to Screen, keyboard and mouse. Boot and follow start up instructions. Add or modify HAL and INI files and run LinuxCNC. This is really a brain dead installation. John Dammeyer
