I need to retract to a safe location
for B rotations. On the Fanuc controlled machines
the program looks like this:
G43
Z1.0 H125 M50.
To output this my post looks like
this:
G43 Z#V13 H#LOFF #V17
It defaults to Z1.0 unless I add #V13=6, #V13=8,
Etc, Etc. as a User Event for the Z clearance that I want
to retract to. When I want to default back to the
Z1.0 level I add a #V13=1. This way it only changes when I
want it too for the certain tools that I need it
too.
When machining the same parts on all 4 sides
of the tombstone I have the safe retract built into a machine macro
that looks like this.
G91G28Z0.
M28B90 G90 M99 This way it always retacts to Z home before the
rotation.
