Laser Sculpfun S6

Hello,
I’m new here and I just installed a Sculpfun S6 laser with a GDRL driver. Unfortunately I don’t know if I have anything wrong, because i get error 5 when i run initial position command how can i fix?
If that doesn’t work, how do I calibrate the coordinates?

thank you for the advice.
