Yes, some things are just inherently

Gentlemen,
Put the home switch wherever you want it OR wherever is convenient.
You can use the +-sign in the ini file to determine which direction to seek
and search for the home switch and index.
You can then offset the home position to wherever you want it AND
you can put +- in the axis limits

Near the middle might be best, but it needs to be off for half the
travel and on for half the travel.
LinuxCNC knows how to back off the switch if

Actually, this is almost normal for the Z axis. In fact my CAM package

If you would include a link to your ini file it would be much easier to
diagnose and answer.

There are multiple parameters:
1. You can declare the homing switch to be a coordinate other than 0.
e.g. "after we settle on the switch, this axis is offset so this is now
+1.25 inches"
2. You can set axis limits at anything. I probably would never set a
negative coord as a limit but
Just guessing, but you might have software limits set to 0. That'd be a
configuration issue, I'd guess the .ini file or the main *.hal file would
have those in it.
You should be able to travel past the home switch. On a side note, I have
no home switches and will 'manually' home in Axis by
Is there any way to move past home position.
Each of my Axis, X, Y, and Z use three sensors to provide inputs for min
and max limits and Homing. We have the Home switch set about 1 inch
inside the max limit switch. However, We need to raise the Z axis above
the home switch but inside the
