Ian ,
yes sorry it is the default mach3mill.
this is what i'm doing,
run probectrl enter values, press config probeing routiine, comes back you can now load gcode.
load probe25.tap
single step to #1001=1, enter 1001 in var moniter and update, value returned 1
step to #1002=0 enter 1002 in var moniter and update, value returned 0
and so on to #1014=1 ,when i reach f#1001 the feed is entered into mach.
thanks mick.
