Kinematics and Delta Robot

For multicore machines I have found big benefits in isolating the last cpu core for realtime events.
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

Yes I am using a PCI Wifi Adapter. I plug out it and I am scaned bios settings I closed almost everything except usb and Lan adapter.

And YES . I get Servo Thread Max Jitter is aroud 38800 and Base Thread Max jitter is around 42700.

That is much, much better.
Savaal, teshekyr, abey !
Was that correct ?

No. But when you say abey! We are laughing loudly in office. Now we are calling each other as abeyyy!!

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.

Nice !
