When you change the tool number, you must recalculate the toolpath...but why ?
It was really helpful if i can edit the tool number (offset number an tool for me is the same, don´t know anyone use different numbers) in the used tool list, without recalculate the toolpath.
So whats about an direct edit in the used tool list ?
We don´t have fixed tool numbers on the machine. So the 8mm end mill is today T15 next week T24.
Small programs can edit on the machine, but if there are many tools, it is more easy to edit this in fusion and post it again.
