Mach4 General Discussion / script for limit switch override
« on: January 02, 2018, 06:12:00 PM »
I am trying to write a lua function for turning on and off limit switch override. (I can provide more details as to why, but it's not important for this post)
I couldn't find anything in the core API help file that came with our copy of mach4.
Any help or suggestions would be great! 
Thanks,
David

I have a stepper motor driven linear actuator that I am using as my B axis.  When it occasionally gets jammed with something, I have no way of knowing until I check up on my machine.  What I would like to do is set my softlimits slightly beyond my homing switches.  When the machine tries to home the B axis but reaches a softlimit, it will essentially know that the axis is jammed and stop.  When I tried to implement this, Mach3 ignored the softlimits that I had set, because it turns them off when homing.  Does anyone know a way to override this?  This would be a HUGE help! Thanks!
