PCB MILL Need help

I was wondering if i could get help initializing my pcb mill. The pcb mill is a sanesmart 3010 pro. I have added a circuit on the zprobe to help it be more electrically isolate. I also installed limit switches on it. It is running grbl on the wood pecker 3.2 A clone controller board. I can pay 80 dollars for the help.
