Hi, For reasons I dont understand, many people prefer to use extremely legacy hardware to run linuxcnc. the hardware list in the wiki is extremely outdated, and there is no real recommendation on what to buy currently. just for fun I tried to run it on modern hardware, and it worked really well. I used a Pentium Gold G5400 on a rog strix h370 mainboard(dual ethernet), booting from nvme. 64 bit, and efi boot, you cant legacy boot from nvme. I tried the 4.19 and 5.4.19 rt preempt kernel from the debian repo. both get extremely good latency of 1500-10000 ns, depending on bios settings and kernel args. but even the defaults are fine. I tried on a few other non-legacy PCs, and could not find a single one that doesnt work well with rt preempt.
imho rt preempt is the future, as it is maintained, and you can get modern kernels with it. just trying to kill the rumor that linuxcnc doesnt work on new PCs.
