Re: ENA +/- on G0678

Re: CNC12 Tool Touch Off Height Offset Z movement to point #1 Aborted

where did you set the home position? the G28 is set to same position as home in your report, so its trying to move to Z home and notices that z home is below where the machine is now so it won't to prevent a crash. and unrelated but, .1587 turns per inch for X axis? what kind of machine is this?
