PID tuning chapter in documentation should explain use of FF1 and other parameters #2116

Open petterreinholdtsen opened 1 year ago

petterreinholdtsen commented 1 year ago

The chapter in the documentation on PID tuning, <URL: http://linuxcnc.org/docs/html/motion/pid-theory.html >, only talk about adjusting P, I and D, but nothing about adjusting FF1 like the recipe on <URL: https://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tuning_LinuxCNC/HAL_PID_Loops >. Perhaps some of the information from the wiki recipe should be added to the PID Tuning chapter?

Maybe we can add the information from https://gnipsel.com/linuxcnc-old/tuning/servo.html ?

Both seem to have information that would fit well in the pid tuning instructions in that chapter. :)
