Limit switch triggered. Which axis???
« on: September 15, 2013, 09:15:59 PM »
About this message "limit switch triggered"

I have the limit switchs NC.
Debounce interval 500 (then increments 250)
My last setup Debounce interval is 2750. Is that enough?

Something I want to know is:
Specifically. Which axis is the trigger?

The message "Limit switch triggered",
NOT SAY to me, the switch triggered.

That I can do to know the trigger axis?

I appreciate any related information.

Hi Riphet,

My view is that if it is not obvious which axis has triggered the limit switch then it could just be a false trigger. This can occur if the WatchDogs are enabled (Config / Gen Config) or if electrical noise is an issue - also mechanical vibration can activate some switches

Could you provide more details of when the limit switch triggered event occurs ?

Tweakie.
PEACE

That's the problem:

1. - Use watchdog is disabled.

2. - I do not know which switch triggered.

The machine works normal, but randomly trigger this message and stop.

Appears noise, but it was 4 months working without problems,
with Debounce interval ats 500.

Now Debounce interval is 3000. Is that enough?

First thing to ask is are you using the parallel port or an external controller?
