Help Needed: Cracking the Code on LinuxCNC Servo Homing Setup!

Here is the latest ini. Still having issues while powering off lcnc, but after homing, jogging from 0,0,0 to any other point, and power off, does not complaining about softlimits. Am I missing something? 

Here is how I did it.

But still having issues to turn off internal homing, after homed.

This is how I solved for now: moved all axes 1mm out from home 0 point. 

This is not a good solution, just temporary, but working. Still not understand how soft limits work (in lcnc), and how to stop the machine in a distance from the switches. 


 

Nothing happens if

home_offset = -1

or

home_offset = 0

the machine still can go to the switch.

Since 'home_offset' is the standard procedure for this and definitely works on my machines I would guess your custom homing comp does not support 'home_offset'.
Does the drive use the limit switch for homing?

Yes, the drives using limit switch to homing. The homing process is:

1. Fast limit sw search
2. direction change at low speed
3. stop at first z signal
4. lcnc homed

It is possible, the offset is not implemented. I'm using Marco Reps modifications with a custom comp file, which is based on standard homing.c

What is the desired motion if home offset is on? Let say 1mm.

Here is an example of a Z-axis on a mill using a limit/home switch at the positive end of travel and an index signal from a linear glass scale:

Looking at 'el8_homecomp.c' confirms that 'HOME_OFFSET' is indeed not implemented:

 

Looking at the default 'motion/homing.c' it may not be all that much work to get it to work:
