Well as a few of you know im in the middle of building my machine as if i haven't enough things to think about and stress over, i decided fire up my mach3 software and give the motors that i have at tho moment a spin! all was working fine untill just, out of the blue the Z axis will not move and i keep getting the error safe z turned off ignoring safe z move! ive not touched anything since last time i had a mess with it and it was working fine! it wont move when im in the motor tuning setup either.

Ive looked at a few settings but im new to all this and i cannot see what could be the problem!

Anyone have and ideas or has come across this before?
