2. Why would you delete the complete hal? and Linux will not rewrite anything if not explicitly told to do so.
3. Yes there is, but on a lot of documentation for both the LinuxCNC and cards in use.
4. Yes, you need a DVM with memory function or min/max function.
5. ............... i see PCW has already replied

1. I´ve only run the Pnccwizard and added some outputs, I´ll try tomorrow if one of those comments removed does help
2. just to see if anything in the hal is causing the restart, maybe i made a mistake, but the hal was restored.
3.
4. I´ll try to check with my oscilloscope with high timeline
5. Yeh, but somehow, in the very exact moment i start Linuxcnc the computer crashes. I can let the pc run a whole day without crash. As soon as LinuxCNC is running it crashes sooner or later. And in alot of cases right when LinuxCNC starts. Is there a way to reset the mesa cards to it´s very orignal state ? I can remeber that i had flashed them with some firmware long ago, maybe that could be a cause, but since they are running fine (except the crashing pc) i guess they are ok.

Is there a Linux guru that can tell me how to read Linux error logs ?

dmesg
or
sudo dmesg

I've found a new 24v psu in my garage that I've bought for another project. I've hooked it up to supply the 7i77 and the 7i84.
No change. Still random restarts.

As far as I can tell. It's LinuxCNC itself causing the restart.
I connected the latch relay directly to the 24v so I can the machine into power mode without the card doing anything. Doesn't even need to be connected.
Then I've run my linuxcnc configuration I'm using all the time and ou of 10 tries it crashes like 7 times right on splashscreen.
Then I've tried the axis_mm configuration by right click on linuxcnc and choosing one of the axis basic settings.
I could start linuxcnc 20 times without restart.
Then ive tried my config again and got instant restart.

I'm sure my ini or config have a problem.
I'll try to post both of them

I would try an external 5V supply so any machine side 5V issues
do not affect the PC

You might also try another PC, maybe there are PCI issues of some kind

- Maho mains is ON

- i start Linux cnc
- when the Linuxcnc Splashscreen closes -> restart.

That is telling you exactly where the problem is......

2. I´ve then deleted almost the complete HAL but linux rewrites it..
3. Is there a documentation what LinuxCNC does with the cards on initial start ?
4. Or can i monitor it ?
5. So I think linux is doing something to the cards that causes a restart.

1. Yes it does, but it is not Linux at fault.
2. Why would you delete the complete hal? and Linux will not rewrite anything if not explicitly told to do so.

-
-Plug the PC on another socket in the shop, preferably not the same phase as the Maho,
-find another PC to test with, they are 50$ and up, so not worth the time lost chasing gremlins,
-if you do have a DVM with the above functions, monitor the 5V supply for both min and max values, under no circumstances they should deviate by more than 5%, or from 4.75 to 5.25V. I think for Mesa that should be even lower, like 2%.
-check if the PC power cord has grounding, do not use anything without ground on a machine.
-power the PC and 7i77 without powering the Maho, see if you get restarts. If yes, throw that Pc and get a new one. If no, something is wrong with one of the above or with the wiring/grounding or the supply voltage is dropping to the point of resetting the PC when Maho is turned on.

Did you try any of those things???????????????????
It is getting tiring to see so many replies to help you being ignored by you and insisting that LinuxCNC is at fault. It is not.

- Ive tried 3 different power sockets for the pc
- I cant buy another pc and i really dont want to
- i don have volt meter than can memorize voltage drops or raises
- pc cord has grounding
- I can do whatever i want with the maho. I can turn itś powerstages like 100 times on and off. The pc only restarts when Linuxcnc is running. Very often the pc restarts the very moment i start linux cnc.
- i have 24v from external power source
- i had 5v from external power source.

Nothing really helped. Itś fact that the pc only reboots with linuxcnc running and 24V rail powered. Machine can be latched on to hold 24V or not. Both are possible.
And for real, in like 7 out of 10 cases the pc restarts as soon as linuxcnc finishes splash screen.

Iĺl try to copy my config and check if leaving something out helps.
