You can disable all or individual drives to the stepper but how you do that depends on how your controller ( power supply,
dirve, etc. is wired). SAFETY is important, ie; maybe you want to take a measurement or change a tool , and you don't want the motors turning. You don't want to rely on software for this.
I use Geco 201's and have the disable pin switched for each axis, and another which will disable all axis's, also another emergency switch which will shut off power to my controller ( that one is on a cord which can be hand held). I will
call these "hard wired switches".
Post what kind of drives, etc you are using and surely someone will be able to relate to what you are using.
If hard wired is not what your interested in then just say so.
