Z axis limit switch question.
Posted: Fri May 01, 2015 11:43 am
I have an LO-X7 DSP controller. I have Z+ and Z- limit switches installed. The switches are wired Normally Open.
When I activate the switch the 24V on the DSP goes to zero as it should, but it has no effect on stopping the stepper motor.
I have the hardware limit box checked on the Manufacturers parameter sheet.
The Z- switch does work to reset Z if I enable Z axis home on power up, but it won't function as a simple limit (+ or-).
What am I doing wrong or what am I overlooking.
I have the same issue with X+ and Y+ not working as simple limit switches. X- and Y- work fine as homing switches but not as end limit switches.
I also have the same issue as Enphector talks about in the post below relating to flaky behavior of the hardware limit option unchecking itself.

I must be missing something pretty fundamental but I'm kind of at a loss.
Anybody help?
Thanks
