Laser camera not working

Hi, i received and built my machine this weekend but it doesnt seem able to do a camera calibration for the laser or when i get it to take pictures of the bed in the software on my laptop it just has black squares with some blurry bits, nothing representing what is on the bed at all. I’m away for a few days so unable to take screenshots to show whats happening just yet.

Has anyone else come across this?

sorted! i needed to click on the calibrate button in the software now its spot on
