Hi"

I am new at this game and I have been trying to set up CNC machine. I cannot get past first base as I keep getting an offset which I cannot get rid of.

All my homing switches work and I have read all the manuals. When I go to home ( reference all ) the machine stops in all different positions.
The offset keeps getting digger.
I cannot run the machine as it will crash ,

I also get a error Z not set
Is there anyone that can help me please

So you are saying when you press the RefAll the machine moves towards the switches but stops before it gets there? If so then you either have electrical noise or vibration is causing the switches to trigger. If the former try going to config menu then General Config and set the Debounce Interval to 2000 and see if it helps.
