Homing using index

Greetings, I have a Deckel maho with linear encoder scales. I want to home the machine using Index in my linear encoder scale. the wires of index are connected along with their respective encoder wires on TB3. I don't know which pins I should assign for homing in PNCCONF. If I don't assign the homing pins then I am unable to edit the homing settings in PNCCONF as seen in the attached picture hence I am unable home the machine later on.

Hello Andy, i am not a programmer so i can't really get through it. Can you explain it a bit more? An example would be very helpful.

You need to take the time to read and understand these docs. linuxcnc.org/docs/2.9/html/config/ini-homing.html
PArticularly the diagrams,
No programing required...

  i read the document, but still it's not quite clear to me as what specific line i have to add. i understood the ini file lines that andy pointed out and i am able to run the homing cycle also after adding those lines. but it doesn't detect the index mark of the linear encoder scale . i am unable to understand the hal lines that andy is pointing out. a similar line is already written in the hal file, i am attaching the picture , can you point out where and what line i have to add?

If index is not detected, that may be a hardware issue.

To test,

1. Disable the drives
2. Monitor the encoder position and x-index-enable in halshow/watch
3. Set index enable true (halcmd sets x-index-enable true)
4. Hand move the axis past an index
The encoder position should be zero'ed and x-index-enable
should be set false on index detection

Greetings PCW, i tried what you asked and seems like there is no hardware issue, the linux detects the index perfectly well and responded as you suggested. I guess the real problem lies in the hal file. what line should i add in the hal file so that when the machine hits the index while homing, it gets zeroed.

EDIT:
i solved the problem, thanks to you guys. you guys are the best. i copied some lines from my last time and it works now. the problem was with the HAL only. thanks a lot guys.

it wasn't adding those lines because i wasn't choosing any home switch inputs in PNCCONF but then i used some random inputs so that it generates basic lines for inputs in both hal and INI files. then i switched the HAL input lines with the encoder inputs and voila , it works now. thanks a lot guys, a big help. although i busted a radial bearing while doing all this , i need to fix that first,. thanks a lot guys.

Hello
I just connected the z pulse signal from the encoder and I want to use it for homing.
(A, B are not connected) Open loop system
This is how I configured the ini and hal files.AndBut when the homing command is sent, the joint moves until it reaches the homing switch (for example, position x=20), then the axis value immediately becomes zero and moves in the opposite direction until it reaches the index pulse, and when the index pulse is received, the axis value is set to 20 and moves at maximum speed until it reaches zero.
What should I do if I want the joint to stop immediately upon receiving the index pulse and consider that point as the origin?
Is not connecting the encoder the reason for this last movement?
