Linux loads hardware modules at boot time, no matter if it was plugged in during install or not.
Proprietary modules/drives will nor be loaded during install nor after, they will have to be installed separately, like NVIDIA or AMD ROCM drivers.
Linux is extremely good with this as you can even add hardware while the PC is running, granted that hardware does not require BIOS initialization, and it will happily load required modules, like USB video grabbers, and in some cases SATA and PCI-E stuff like hard drives and NVME if set to "hot plug" in BIOS.
I recall having to reboot the windows PC to be able to use the USB stick you just inserted...ah the trauma!!!

FF1 can be tuned further to flatten the ferror plot

Once this is done, you can usually add some I term

If a SSR seems on all the time, it may be that you have the polarity backwards

Getting back to this project.  Servo enables are working now, and started the drive tuning.  Was wondering if someone could take a look at the attached images and provide any recommendations.  Drives are moving smoothly with the tuning parameters, but wondering if there is further improvement to be made in the servo tuning.  I also have an issue where the torch enable signal is being sent all the time.  I have not fully debugged this yet in the wiring, but any suggestions on if there is a configuration issue that could cause this?  The LED on the SSR on the board does light up when the torch pulse is toggled to on.
