This is the conundrum with this method.
How do you index?
How do you make it repeatable?
With the crossfire pro you have no homing , you have no limit switches so effectively you’re completely blind with orientation .
If I was doing this operation I would set up a jig by trial and error and cut out as many of those pieces as I could with that jig during that session.
Here is a topic that gets into some indexing.
Again all these attempts are because the original crossfire and the crossfire pro are blind in respect of the torch:s relationship table.
