Tool change  
Hello,  
I am generating G-code using Estlcam.

During the tool change performed by the gSender wizard—using the “standard re-zero” strategy—the new tool passes too close to the work surface.  
If the workpiece isn’t perfectly flat (which often happens), the tool leaves a nasty scratch.

How can I increase the “air-travel” distance at that specific moment when cutting resumes?

The clearance height is set correctly at 5 mm, but that setting doesn’t affect the resumption of work—I’ve already tested it.  
Thanks in advance for your help.
