Error and CPU load Gmoccapy vs. AXIS

Hello,

I have this G-code file
leteckaposta.cz/408997868
It has only 51Mb.

When I run this program, after a random amount of time the machine stops and displays this error:
 
Does anyone know what this error means?

I can rule out a miswired wired Emergency STOP button as I have it disabled.

Computer latency is also good.

The problem occurs on two completely different computers.


I don't know if this is related to my problem, but I found that if I just load this program I get 100% CPU usage. The processor is still busy even though I'm doing nothing. Preview rotation is choppy and slow.
 

When I load this file in the AXIS GUI, the CPU usage is fine. I can have the program running, I can rotate with the preview. The preview rotates beautifully smoothly according to the mouse movements, but I don't use the CPU at 100%.
 
I tested Gmoccapy in version 2.8.0 and also in version 2.8.4. The behavior is the same.
 

I have bad news. The program is stoped in AXIS too.   This is friends machine. He tried it several times. Sometimes it is stoped after one hour, sometimes after two hours. It is randomly.

But in the AXIS the error has only second message. "Joint 2 following error"

Here is the G-code:

First link for G-code dont work.

Here is config for Gmoccapy:
 

Here is config for Axis:
 

the Gmoccapy error 'spindle off etc' is unimportant, it's just the code turns the spindle off after the machine has tripped for joint folling error and of course cannot.

I am makeing some tests. I have same theory. I will get report.

Hi,

at the moment I can rule out a connection between CPU load and the machine stopping. Anyway, I'll explore the 100% CPU usage later. Right now I want to devote my time to the cause of the machine stopping.
