Hi, I am quite ‘green’ with SGP and have recently fitted a Sesto Senso 2 to my Skywatcher 120ED refractor. I have calibrated it in the proprietary PrimaLuceLab (PLL) software and found the racked out maximum to be around 191000 and focus to be achieved around 131000.
When connecting to the focuser with SGP it reads back the current position of the focuser ok, however when I tried to follow the set-up guide for auto-focus to calculate the step size required as soon as I tried to move the focus position out SGP gave me the 100000 step size error and pulled the focuser into the 100000 position. I move the focuser to 80000 and then tried to go beyond 100000 as an experiment but SGP overrode my manual focus point choice maxing out at 100000.
I have been looking and have been unable to find a workaround apart from not using the focuser with SGP. I did see one post on another forum which linked to a Twitch stream where PLL apparently described a fix but unfortunately that link is dead.
I also noted that the temperature initially reports back from the focuser as -273 degrees taking a couple of minutes before the reading is correct, this is the same for my weather box that is attached, not too worried about this behaviour, only mentioned it in case it is abnormal behaviour.
I have attached a link to the log where I tried the above.

Hope the info is helpful to finding a solution or to point out where I may have missed something as I was setting up the focuser within SGP.
