General Mach Discussion / Possible to Enable Softlimit while Homing?

« on: May 26, 2011, 03:51:28 PM »

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!

Had a similar problem with a home-built machine.  I had my debounce interval too low.  I have it set on 150 now, and never have a problem.  The wiring was too noisy to hold a steady signal from my limit switches, so Mach3 read it as hitting the switch, coming off, and then hitting it again, before it ever traveled away from the switch.
Just a thought.
