I have the 4x4 gantry kit and have everything set up but it will not cut. When I load gcode into mach3 and try to hit run the gantry moves and the torch goes down to make contact with the metal. After making contact the torch fires and instead of moving to make the cut it just stays in the same place blowing a hole in the metal and that's it.
Does anyone have any idea what this could be? I have been trying to figure this out for days now.
