Mesa 7i76e - Joint 0/2 following error

Unfortunately, "more powerful" doesn't always mean "lower latency"

I don't have a 7i76E so can't give any specific recommendations, though.

Before you give up on your current CPU, What OS/ kernel are you using?
(uname -a will print the kernel version)

If you are using the years old 3.2 Preempt-RT kernel you may do better with a newer kernel
(Trying the new Debian Stretch ISO + 4.9 Preempt-RT kernel is at least worth a try)

Hi Andy,
true!

Hi PCW,
uname -a
Linux LinuxCNC 3.2.0-4-rt-686-pae #1 SMP PREEMPT RT Debian 3.2.89-2 i686 GNU/Linux
Thank you for checking!

Regards,
Jack.

I would try what PCW suggests. If you buy new hardware, you probably will need to use a more modern build of Linux to get the driver support so you might as well practice on your existing hardware!

I have not got any direct experience but when I was looking for hardware, Celeron based chipsets were recommended. PCW will know more but something like a N3160 cpu which will save you some money. Your Chinese friends will have one....

Hi Rod,
I found this refurbished PC, not expensive, but it may not be a Celeron.

This was the cheapest, though.

Jack, sorry I can't really advise you on hardware. There are a few Core2's listed here
