Hi,
We have a couple of CNC machines running a mesa board with very similar NUC Intel PCs running LinuxCNC
The Mesa board should greatly reduce critical timing requirements for the host machine, I've turned off everything in the bios that is suggested and whenever I run a jitter test I get decent looking numbers. But sooner or later I always seem to get a communication error, apparently related to timing, it's like sooner or later something somewhere holds things up for just too long.
Now one PC has died (power supply failure) so it needs to be replaced anyway, and I'm wondering whether we should try going down a different path with something ARM based such as a Pi 5.
So, is it a good idea? Will it improve things? Are there other better/cheaper allternatives?
regards
Jonathan
