User Defined Program for Homing

Hi,
Newbie here, I have a custom program for homing and Tool Change in C/C++.
I want to replace the existing homing and Tool change  to integrate my homing an tool change program with LinuxCNC .
I don't know how to approach this problem so need some help to figure it out.

Thanks and Regards
Abhishek

homing.c  controls homing. 
Start here for a custom homing component
linuxcnc.org/docs/2.9/html/man/man9/homecomp.9.html
You need V2.9 or 2.10 for this.

Hi Rodw,

Thanks for the Reply.
I am using V2.8.2 so the above link might not work for me, is there any other alternative.
If possible can you help with Tool Changer.
As different machines should have different way of implementing Tool Change, so how do we integrate our custom Tool change program in LinuxCNC.

Thanks & Regards
Abhishek

V2.8 does not include the homecomp functionality. You would have to modify homing.c
Consider upgrading to V2.9 to get a more modular approach
