REM Updated 30 Aug 2018
REM Auto Tool Zero Z- Metric 2 pass Version
REM Based On the BigTex script
REM (09 Feb 2018) Hint added To Material Thickness offset request box.
REM (20 Feb 2018) Request To touch the touch the touchoff plate To the bit To start probing added. Thanks To Glen Higgs For this addition.
REM (27 Jul 2018) Minor changes To Error Handling And Grammer correction
REM (30 Aug 2018) Feedrate override safety Reset And restore added.

And do I need to connect the B- purple and black wire to pin 4 ?
And, how do I make it so that I can enable from pendant (and not have to hold button permenantly)?
