Do you have your stepper limits setup properly? (for noobs)

[guru_florida]

I am sharing this story for all the noobs out there:

I've been using emc2 for quite a while with limit switches on both axii ends. I just installed some opto interrupters I made and decided just to go with single ones as homing sensors and rely on software limits. It just clicked how software limits really work with Emc2.

Before if I approached my machine limit I would get a limit error and the machine would stop and leave Enabled mode. I figured software machine limits would do the same thing. I was wrong, the machine will go to the software limit but will simply stop there but still allow other axii movement.

I put my homing opto switch just out of the bounds of the machine limits. Now once the machine is homed it never triggers a limit error! I can be confident the program will finish since software limits are checked when the program is first started.

Also, learn about "Touch Off" if you havent already.

Well, how do you like your setup now? Can you post your new ini file please?

I love it! I am doing jobs that are tight to the extents and aren't hitting limits and wasting material.

I'll post my ini later when I get on my machine again.
