Hi
No-one seems to be rising to the challenge
I have had to scale down the distances involved to get them to fit into a sim
The first punch is represented by the negative Z moves, the second punch is represented by the positive Z moves
Since there is only one tool origin on a sim, the moves are in the same plane but shown #<_between-punch-heads> apart
(ie offset from each other when in reality they would be operating on the same point on the workpiece)
This is not a polished piece, just an example of using a sub to activate the second head when the first is #<_between-punch-heads> ahead of a hole
There are many ways to do the same thing
Plot looks like this
regards
