LinuxCNC stops during process was created by maexbecks
Hi,
I have a problem with a machine of mine. It runs on Ubuntu 8.04 and LinuxCNC 2.3.5 with
all new updates for that system.
I let the system start by an output from another machine, which I declared in the HAL File:
The program starts mostly without any problems, but sometimes like every 1000. time the
program just stops and creates this output:
program continues from the point where it stopped. It also mostly stops in the same line,
but again for like 999 times the program runs perfectly fine.
What is the problem here?
This is the program where it infrequently stops, but I don't know exactly in which line anymore:

I think what may be happening is that you are pressing the button between the system polling mode.auto and program.run.
The parallel port updates on a fixed schedule in the real-time thread, which interrupts the user-interface code.
The solution is probably to test that the mode is correct before setting run. Even with this there is then a small chance of setting auto-mode and then releasing the button before run...
If you already have some and2 functions loaded then you will need to edit the quantity of them and either give them all names, or use and2.5 (or whatever) in place of runbutton in the above.

Thank you for your response. I will try that.
Is there another possibility to start the program with an external signal on the parallel port?
But here the only problem would be that the programm would not start at all? So I could give the signal as long as I know
that the program was started and this problem would be gone?

Yes, as long as you press the button until the program starts, it is all good.
It is just that once every seldom, if you press "run" then change your mind you will find the machine is unresponsive until you press "stop"

There was some discussion that halui and a GUI can occasionally fight for the NML messages.
This may be showing up here.
There was nothing that could be done at this time, if this is what the problem is.

@andypugh I tought about your suggestion today, but since the program stops while the program is
already started, I think it must be something else.
It also seems that the downloadable image of Ubuntu 8.04 with LinuxCNC 2.3.0 doesn't have this
problem.
If there is no other solution I would have to setup the machines with an old version again, I guess.

Is the problem possibly due to noise on the parport line?
Maybe a combination of the and2 (to get the sequence correct) and a long (2mS) debounce would help?

This may be... how can i make the debounce in hal?
Edit: Got it. Lets see how it will work out... Thanks for your help.
