NAME

       homecomp - homing module template

SYNOPSIS

       Custom Homing module loaded with [EMCMOT]HOMEMOD=homecomp

DESCRIPTION

       Example  of  a  homing  module  buildable with halcompile.  Demonstrates required code for
       #includes, function definitions, etc.

       If HOMING_BASE is #defined and points to a valid homing.c file, an example of a customized
       homing  module is built.  This module creates input hal pins joint.n.request-custom-homing
       that enable an alternate joint homing state machine for requested joints.   A  hal  output
       pin joint.N.is_custom-homing verifies selection"

       The  customized  homing module utilizes many of the base homing api routines from homing.c
       without modification but augments other base functions to add support for custom hal  pins
       and  custom  joint  homing  state  machines.   A  user-built  module  will  likely replace
       additional api functions or augment them with other customizations.

       If HOMING_BASE Is not #defined, an  actual  homing  scheme  is  not  implemented  but  all
       necessary  functions are included as skeleton code.   (All joints are effectively homed at
       all times and cannot be unhomed).

       See the source code file: src/emc/motion/homing.c for  the  baseline  implementation  that
       includes all functions for the default homemod module.

       To avoid updates that overwrite homecomp.comp, best practice is to rename the file and its
       component name (example: user_homecomp.comp, user_homecomp).

       The (renamed) component can be built and installed with halcompile  and  then  substituted
       for the default homing module (homemod) using:

         $ linuxcnc -m user_homecomp someconfig.ini

       or by inifile setting: [EMCMOT]HOMEMOD=user_homecomp

       Note:If using a deb install:

       1) halcompile is provided by the package linuxcnc-dev

       2) This source file for BRANCHNAME (master,2.9,etc) is downloadable from github:
