General guide for operating jackpot 3 board

is there a good resource to show how to operate the jackpot 3 board? i finished my lowrider v4 build up to the point where i need to make the struts and have some questions with the software. for example, my z probe doesnt seem to be responding and in the probe section it comes up as a question mark. when hitting the button for z probing nothing happens. is there a link to a guide for how this is supposed to function?

Thanks,

Nick

Hi there. I would start here:

Also, is this a fresh Jackpot3 or did you install anything to the device yourself?

its a fresh jackpot 3 with no modifications.

The probing speed ( feedrate ) is extremely slow so maybe it is moving but very slowly. That got me in the beginning. So you can up the feedrate a bit.
