Look into ISOLCPUS for the realtime kernel.

at the command line run:
$ sudo nano /etc/default/grub

Find the line GRUB_CMDLINE_LINUX="" and update it to:
GRUB_CMDLINE_LINUX="isolcpus=1" (where 1 is the highest CPU core, dual core = 1, quad core = 3, etc)

then run:
$ sudo update-grub

and reboot, your RT jitter times should decrease


Thank you Sockheaven. Exactly, I will try tomorrow.

And, my scaling problem is continuing. I do not understand scaling or specify basic gear ratio. Not only in rotarydeltakins but also trivial kinematics.

Hi Sockheaven,
Now I get servothread max jitter 24000 and base thread max jitter 36000.
Thank you.

There is another user here on the forum from Turkey, so might want to chat with him, but it is hard to find it here since i do not recal his user name.
What problems ?
