New start

Thanks!

That's exactly what's confusing me.
Even when I reset the e-stops port and pin to 0/0 instead of pin 12 port 3 (in my case) I still get ext e stop.. weird!

Are you using a formal release or a test release? If you are using a test release I'd install a formal one and/or contact CNC Drive because if you have disabled hardware e-Stop then it really sounds like some invisible configuration issue or a software bug. I think you should send them a mail or post this on the CNC Drive forum. I am pretty sure you would quickly get an answer there and Balazs would quickly start debugging and solve the issue.

In any case, debouncing is not the right way to go, the problem must be caused by something else. If the e-Stop port and pin is defined as 0/0 then it should not be caused by the hardware.

Exactly!

I am using 1.2047, latest stable release according to cncdrive..
Have emailed balazs, hope he has a solution ;)

Don't know if you are using USB version or not but I'd check your PC settings because could be energy saving shutting down the USB ports when thinks Pc is idle.? This would have the same affect as E-stop to the controller because lost connection with PC which would explain why still get E-stop message when not connected.!

Could even be a program working in the background which try's to check ports etc causing blip just long enough to trick controller it's lost connection.

I thought about that also but he said that UCCNC detects a hardware e-Stop, not that it lost connection.

It might not show as a full loss of connection but does cause's an interrupt just long enough to trick controller. These are the Silly tricks USB gets upto and why I won't use it.!!
Also do you know for sure that UCCNC displays connection lost message and doesn't just throw a Generic E-stop message if doesn't fully lose connection.?

Well during large noise problems (tried unshielded vfd wire) uccnc looses connection with uc300 and can't be reset without disconnecting usb and reconnect.
That is way worse then e stop.
Now when it e stops I can just reset, run spindle and then start cycle again.
But for every time I do so it will run a shorter time before it e stops again :(

USB will generally just fail/lock up. If you do get problems with that, get a USB isolator.
Search ebay for "USB Isolator", and get one that uses an ADUM chip (I think most of them do).

However, it sounds like you have a noise problem.
Simple fix is to add a small capacitor to the E-stop input to the controller to act as a basic noise filter, but depending on your e-stop circuit, it may be better to add a resistor to increase the load on the circuit so noise isn't as big a problem.
The only concern with those fixes is, the noise may be affecting other things, but not as noticeably I.e. lost/gained steps.

This might be it.. not power setting but background programs.
I have checked power settings and they are set to "always on"

I'm using my old home computer so there are all sorts of programs installed. Should test reinstall but I have no valid windows cds left. Stuff like that gets destroyed some were between child 2 and 4 ;)

Its still strange that it starts to happen after about 2h and not when running pockets and contours just 3d....

Hi nr1madman

Do you have fault relais from the drives hooked up to the emergency circuit?

Just guessing?

Hey!

No I haven't gotten that far yet :)
The e stop circuit is made of e stop buttons and a momentary button driving/latching a relay.
This relay supply the signal to the bob for e stop and power the drives psu and vfd.

So in my thinking a fault in relay or e stop buttons would disable drives and vfd aswell...
