Almost- I don’t want to use a bump stop.
In all of my Rhino models I include a centreline at a specific point across the X axis, and two 6mm pins reflected on either side of it, for flip milling.
Yesterday I had some luck in doing the same thing in Fusion, by simply not selecting the waste board/centre line/pin positions as a model when running setup. After importing them into Easel, they looked like they were situated exactly where I wanted them. It seems like they is is positioning the triad at the X Y home position, and ensuring the Z axis is set above the height of the work piece.
I am in hospital for the next week, so I can’t run a test on the machine, but I hope to do so early next week. Thank you for your offer of assistance, if anything comes up, I’ll send you a message and see if you can give me some guidance.
