(superseeded) Linuxcnc on Linux Mint 19.3 quick and easy installation

Tom, do you think the what you have given for Debian Buster could/should work for mint 19.3 too?

Tried it, does not work, next will be a try to add a buster repo

this works:
download kernel 4.9.0-12-rt-amd64 from herehere
gdebi linux-image-4.9.0-12-rt-amd64_4.9.210-1+deb9u1_amd64.deb
edit /etc/default/grubthe line "GRUB_TIMEOUT=5" (lets you choose which kernel you like to boot)
reboot
select the newly installed kernel

The same kernel for Buster will work on Mint but has to be manually downloaded and installed.And the 5.4 kernel will also work on Buster.

Got 4.9.0-12-rt-amd64 installed, rebooted into it and am running lcnc-hw now for more than 35 minutes. So far no realtime delay. Hope it stays so.

With or without base thread ?
You do not need base thread if you do not plan to use software stepping/parallel port, so base thread is useless in that case and might cause worse servo latency.
