Everything you need to know to design your own CNC router

I wanted to check it out at some point though I'm a little scared about the ability of Linux to pulse step and direction with the same precision of a 15 year old DOS setup that has no background tasks and just hits that timer interrupt with very predictable result... The motion generation capabilities of TurboCNC are pretty basic though.

Btw, if anyone is interested that build is documented here: https://www.cnczone.com/forums/diy-cnc-router-table-machines...

I run LinuxCNC on a Raspberry Pi 4, and it works wonders. LinuxCNC is installed with a realtime Linux kernel; it'll run just as realtime as DOS.

I tried as well but found no guides to build a RPi4 LinuxCNC machine with realtime. Can you point me to some tutorial or ready SD card image?

I'll go through my saved links tonight. I remember it was a bit of a cludgy operation, like all things new+Linux, but after I got everything setup it all worked as expected.

I think this forum post pointed me in the right direction: https://www.forum.linuxcnc.org/18-computer/36879-raspberry-p...
