HowTo configure Homing

Hi
I have a CNC control by a Mesa 7I96.
It works fine.
But I would like to add a automatic homing.
I have performe the wiring modification.
Now I have to HAL sensor connect to the IO of the mesa card.

Did you now a nice HowTo document to add the homing function ?
I have try to look but I only found the LinuxCnC documentation that explain everything which is to complicate for the beginning

Thanks

its quite easy
if you use the configuration TOOL
github.com/jethornton/7i96

THE Inputs standard firmware maps GPIO 0..10 to 7I96 TB3 inputs 0..10
YOU can check by
halrun
loadrt hostmot2
loadrt hm2_eth board_ip=192.168. your ip

show pin

OR on running System as you said
FIRST Check the Signal in your Halmeter if it gets on off by hand
CHECK by the PIN of the 7i96

THEN the SAME as the Output with the extra not you can reverse the input
net homein <= YOUR PIN
net home-y <= parport.0.pin-12-in-not
net home-xz <= parport.0.pin-13-in
net all-limit <= hm2_7i96.0.gpio.000.in
and on the AXIS or Joint in the HAL yoiu set

THEN the out to the AXES as
net home-xz => axis.0.home-sw-in or the name you gave
net all-limit <= hm2_7i96.0.gpio.000.in
#
net all-limit => axis.0.home-sw-in
net all-limit => axis.1.home-sw-in
net all-limit => axis.2.home-sw-in

Thanks for Reply

So I have :
Clone the configuration tools
Use it by assign Input to Joint Home
check in the running linuxCnC with Hal meter that
- hm2_7i96.0.gpio.000.in change to TRUE when the magnet is in position for X axis
- joint.0.home-sw-in change to TRUE when the magnet is in position for X axis

- hm2_7i96.0.gpio.001.in change to TRUE when the magnet is in position for Y axis
- joint.1.home-sw-in change to TRUE when the magnet is in position for Y axis

For the moment I do not home the Z axis...

But now I am not sure to understand what you mean with :
- THEN the SAME as the Output with the extra not you can reverse the input ?
- THEN the out to the AXES ?

Thanks

so this is fine now the INI

Mashine is on metric

##############
ALL in mm
#############

So you mean with the tools I have set the configuration in the hal file.
And I have just to modify my ini file ?
And you provide your ini file, so I just have to add the
HOME_OFFSET
HOME_SEARCH_VEL
HOME_LATCH_VEL
HOME_FINAL_VEL
HOME_SEQUENCE

With some value and it should works ?

Basically yes, you need to set these values for all axis in your .ini file

The definitions of these values, and how they affect homing are described here:

linuxcnc.org/docs/html/config/ini-homing.html

Ok thanks
I think I begin to understand better this page now
And will the homing be perform automaticly at power on ? or do I have to use the LinuxCnC to activate it ?

Stupid question ... I just perform the test
And it does not start automaticly...

You _can_ home automatically (when LinuxCNC in changed to machine-on state) but for many machines, this is quite dangerous...

I belive you but I am also curious
Could you explain wy is it dangerous ?
