Hey guys, im going to try and explain this the best way I can so bare with me.

When I make a cut on my cnc I'm usually using multiple tool paths one after the other with a tool change for each tool path, so when I start mach3 I jog to the centre of the workpeice and home it a couple of inch above where I need it to be and the dro then reads zero on all axis but on one of my other jobs I accidentally saved fixture when I shut mach3 down, so now when I try to set my home position the dro doesn't zero itself. Can anyone help me reset my home position?

Thanks
