# 7.2 Options in extstgmot.c

Your system may require changes to extstgmot.c. After making any changes you will need to recompile. Here are some of the options from the source code.

> /* Uncomment any of the following declarations to inhibit
> the use of home switches or index pulses when homing, or to
> ignore limit switches if you don't have them. */

> /* Uncomment NO_HOME_SWITCH if you want homing sequence to
> ignore the home switch, and only use the index pulse for homing.
> This has the effect of making the home switches always appear tripped. */
> /* #define NO_HOME_SWITCH */

> /* Uncomment NO_INDEX_PULSE if you want homing sequence to
> ignore the index pulse, and only use the home switch for homing.
> This has the effect of making the index pulse always appear present. */
> /* #define NO_INDEX_PULSE */

> /* Uncomment NO_LIMIT_SWITCH if you don't have limit switches.
> This has the effect of making the positive and negative travel
> limit switches never appear tripped. */
