The home position was just set at 6" arbitrarily.
That's what I said. But then the home position may not be called home
position. It might be a workpiece origin, a reference point, what ever.
Homing is complicated!
Not at all! But wordings and diagrams should be clear and understandable.

Fusion360 CAM assumes that a G53G0Z0 will retract the tool to the top
of Z travel. I have seen a number of

I didn't create the homing routine but it seems reasonable to me.
Linuxcnc is capable of doing exactly what you are used to, just set some of the
settings to zero.
There is a case where the home position MUST be

but it also allows one to set the origin anywhere and adds an optional move

What does the "loadrt hm2_rpspi" line look like before twopass processing?

Reinhard,
I agree that it's logical to use positive offsets for tools in a spindle
(since a negative physical size is nonsensical). However, what if you have
an auxiliary spindle with a tool tip above the zero height of the main
spindle? I'm not saying that's a wise choice, but it would be

The problem seems to come from people thinking the contact with the homing
switch is where home is.
which is not surprising, as when you ask linuxcnc to
