Write down your process step by step. You always write just about plate solving. There are three plate solving processes, one of which is performed at the PA. Second you can start on the left side of the app and the third is executed after the GoTo.
What you write sounds similar to the problem I have from time to time. The PA always works perfectly for me. Every now and then I have plate solving problems after the GoTo.
What has helped me to reduce the problem to a minimum is that I first go to the home position after the PA. And only then with GoTo to my target.
When I change the target, I first go back to the home position and then to the new target.
If an error then occurs, I go to the home position and switch everything off for a few minutes. I disconnect it from the power supply. And then, as if by magic, everything works perfectly.
It is crazy that such problems occur at all with the basic things this system is supposed to fulfill.
