Install parallel port

The parallel port is not the reason for LinuxCNC exiting

HAL: ERROR: bad position: 0 or
trivkins: already exists

are the issue

Can you post your hal and ini files?

Hoi,
I have run a "blank" stepconfig wizard. Named "my-test".

In the wizard only the name changed, the rest the "basic" settings, then in the hall file the port address changed to "ef00"
The same result, the machine does not start up and displays the error screen.

Also the same with the second address "ee00".

attached "show_errors.txt" the report generated by this error message.
also "my-test.hal" and "my-test.hal"

"Schermafdruk op 2021-03-09 18-02-05.png" is a screenshot of this attempt

The errors you have noticed are probably related to my joy pad.

"myn-cnc.hal" and "myn-cnc.ini" are the files from my original configuration.

Looks like you accidentally pasted the error message into the hal file:

addf motion-command-handler servo-threadinux parallel port @57344 not found

Indeed it looks like it, but in the "new" hal-file it is not and it does not start up there either, but there is an error message

"addf motion-command-handler servo-threadinux parallel port @57344 not found"

probably caused the "HAL: ERROR: bad position: 0" error

What is the current error?

With the "blank" stepconfig (see previous message) Again that "port was not found ...."


I can still assume that with a new "stepconfig" and no change other than addressing the parallel port in the hal-file, the machine should boot instead of not booting and displaying an error report.
So there is something wrong with the port addressing. linuxcnc finds no port at the address specified by lspci.
The question is how do I find out with which address linuxcnc finds the card.

Tomorrow I will find another computer and install everything again, maybe that works.

I dont think so, the parallel port message is a just warning (and maybe unimportant)

It looks like the error that stooped LinuxCNC was graphics related

Of course it could, but then it seems to me to be a bug in linuxcnc because when the process is interrupted at startup, for graphical reasons and only the port is reported as an error.
And why is it not listed as a warning or note, but as an error.
For me the botomline remains why does the machine not boot, if this is for graphical reasons how do I fix that.
The graphics card is also a plugged-in version, as recommended.
On the system, other graphics applications, with a much higher resolution than that required by linuxcnc, will run fine.

When viewing the error report, you see
It is reported that the graphical environment is starting up, then the port error is determined and immediately afterwards the shutdown is done.

So the case is stopped not after starting the graphical environment but only after the port error has been determined.

I am a novice in linuxcnc and linux, but I am quite familiar with computers. I am open to explore both avenues.
