Plugin to control arducam motorized focus?

I use the plugin put out by arducam directly and it worked last time I tried it after finding one fix on the system side. I updated the instructions on the plugin's listing accordingly.

talking about the link to github in thread history cause I tried that too. I think I might be updating wrong config.txt maybe. I pulled sd card out of pi put in reader and added the lines to the config on the sd card...Is that the right one??? First pi never messed with before couple days ago so bear with me. I am having to do a lot of googling to keep up...

I think I may have found it, I did not do this part till just now...
sudo raspi-config

after fighting with this for a day, I finally got past unable to use smbus now I am getting

Trouble accessing camera. I2C bus failure. Is camera plugged in?
I have a pic on the app so YES camera is plugged in you goofy plugin...

Ok, Finally got it changing SMBus(0) to (10) did the trick.
Thanks

I am new to all of this, so I'm sorry if this is obvious - but how would I go about to edit the init.py file? Would I be able to edit it via SSH using Putty? Thank you so much!

I won't do this to code from someone else.
