Machine reset
« on: October 20, 2014, 07:56:51 PM »
I am building a wood router and having a problem with the control resetting.
It will only reset briefly 1-5 seconds and go's right back into estop.
During this short time I can move the axis motors and they sound good.
Just don't understand why it keeps going into estop.
Checked all my switches, they are OK and all the LEDs are out.
Can anyone help?

Sounds like electrical noise being picked up on the E-Stop or Limit inputs. You could try setting the Debounce Interval (on General Config page) to 2000 to see if that helps. If it does then it would seem noise is the issue and ideally you should shield and properly ground all of your signal wiring.

Thanks, that worked!
I will change all my switch wiring.

Everyone
I'm still having trouble with my router going into estop
I have replaced all of my limit and home switch wires to 2 conductor 24 gauge shielded wire.
The only way the machine runs for a short period of time is to set the Debounce interval on the configuration page to 2000
I still must have noise somewhere.
Could it be one of my switches is not too good?
Any ideas?
Thanks
Tim

It could be the switch bouncing.
Do you have the shielding grounded only at one end and all to a single point with that point having an earth wire?

I have them grounded at both ends and even ran an extra wire to ground everything.
I did have a little luck. Since I am running a touch screen monitor on my control panel I ran a ground wire to the aluminum frame and things are better.
It now runs with debounce set at 2000.
Thanks

The current thinking on grounding is that only the control cabinet end of the shield should be grounded and that all grounds should be to a single stud and that stud connected to Earth.
If you have two ends connected it may cause a ground loop, so disconnect at the switch end and see if it helps.
