Try homing the machine. The jogging down to the top of the part and setting 0 for the z
If you need to go back to machine 0 thy a G28 which will put the machine at home without reseting anything.
This all asumes that the machine has home switches.
If the machine doesn't have home switches it becomes more complicated.
Let me know how you make out.

If you are still having problems, let me know what version of Deskcnc you are running and if it is a first gen or second gen card.
