Hi,
How does one program FreeCAD Path to raise the Z axis after I've manually zero'd the endmill to the starting position/origin or to change tool bits?
I'm using a Shapeoko CNC router for reference.
FreeCad Version 0.19

Re: How to raise z-axis for tool change
If you zero manually, you must have the tool already inserted. For the intermediate tool changes the tools is raised to the clearance height. See the section "Heights and depths" in the Path Workbench wiki.
If you need something else: You can always insert a custom command.

Re: How to raise z-axis for tool change
Depending on your physical setup it may be easiest to just jog the control to raise the z.
The FreeCAD Path gcode will automatically bring the tool back down to the clearance height when you are ready to start the next job or continue with the existing job. If your zeroing process was properly recorded by the machine controller this should work perfectly.
Otherwise, just do what Chris said.

Some of the Post Processors have a Tool change option eg grbl has --tool-change.
Double click on the Job, select the Output tab, then hover your mouse over Arguments field to see all the options for the selected Post Processor.
