Installing Mach 3 is driving me mad!

[tonygagey]

Have you set it to mm in Mach post the top 30 lines of your gcode.. I take it when you make a Z move to cut it does a -Z move and not a +Z There is nothing wrong with Mach it just need to be set up correctly then you will be fine.

Set To mm Yes. You want me to post the first 30 lines of gcode but not sure how?will try to copy + paste here
