I just installed the default LinuxCNC Debian 12 to a dedicated desktop PC. There is a Tormach 770 PNC configuration available without anything special, and I've loaded that (though I am working with a 770MX, it is not connected to this computer). I am not a machinist, and I know very little about LinuxCNC, although the Tormach PathPilot is derived from LinuxCNC. From what I can tell the 770 PCNC configuration should work, and it sort of does. I can load a simple g-code file which I've used on the 770MX, and it shows the same graphical display as the actual 770MX (I also imported the tool table from the actual Tormach). The problem: There is no way to "run" the code.

I'm attaching a screenshot. You can see it is in E-Stop, and the buttons I think are for starting cycle (which is unclear if those are for that purpose) are grayed out. Menus do not have any way to take this out of E-Stop or reset. Maybe there is some added setup needed for this to be a simulation without hardware? Any suggestions on what to look at to make this run like a PCNC 770 from Tormach?
 

-power brownout
-lighting strike even several miles away
-processor had a hiccup
-failing power supply
-failing memory or memory controller
-failing capacitors on PC
etc
If any of the last 4, the issue will occur more often with time.
If the second, not much you can do.
If the first thing, and if this is a parallel port setup, and this happens again, see what equipment did you turn on in the house/shop/neighborhood, as big power draw equipment can cause this, easily, and they do for sure cause power brownouts.

Greetings,

I was machining two parts that I have run before at least 30 times.

First part machined as expected.

The second part got 3/4 through the program and the spindle and axis motors stopped.

Also, the AXIS screen was frozen up. No response to keyboard nor mouse.

I turned off the power and rebooted.

Next I started LinuxCNC 2.5.5. All went well.

Reloaded the program, dialed the part back in, and reset Z zero of the cutting tool.

Pressed Cycle Start and the program ran fine.

So, what happened?

Is there an error log/file I can look through to determine the cause of the shut down?

More clues.....
