Thanks for your fast reply.
That's the output of "gpioinfo", looks ok for me:

Hi Chris,
how to install this widget? Only copy the file indicatorMixIn.py to /usr/lib/python3/dist-packages/qtvcp/widgets ? Can it then be used with Qt Designer?

Are you using position-interpolated with your 8-count encoder?
Is there any quantisation of the error you see?
I haven't looked at the spindle synch code, but if it tries to "start early" before the index then possibly a low-count encoder will make that more difficult.

Not sure what P value in the ini.would do regarding servo drive tuning. this is position control ethercat.

I don't see any P value.

There is also "psng" and my own fork of psng here:

(My fork is adjusted for Gtk3 and Python3, but isn't currently working for me, I get no graphics in the tabs)

Yes, you are right, there is no error on multiple constant speed
paths, I had neglected to 0 the q parameter when testing.
This is because the return path has a constant x distance from
the cutting path.

You get the error if you change the spindle speed (or motion constraints)

Basically I would think the the z motion should be strictly geared to
the spindle (+- any deliberate offsets like "q") just like a mechanical
lathe.

Why does it seem like everyone here is Australian?

Category: Off Topic and Test Posts

When I first started with LinuxCNC the vast majority of the developers were in the USA. (with the exception of a Romanian)
There has definitely been a shift to Europe and Australia, though many of the folk here are still in the USA.
FWIW I am in the UK, because my antecedents managed to avoid being transported.

Which version of Linux, LinuxCNC and psng are you using?

I have done some work on psng to adapt it for Gtk3 / Python3 on Debian 12+
However, on my test machines, whilst it loads without errors, there are no graphics visible in the embedded tabs.

Have you run the "gpioinfo" command? That will list the available pins. If it doesn't work that may mean that you don't have gpiod installed.

Is your user account a member of the "dialout" group?

Not able to get outputs on GPIO of Raspberry5

Category: Installing LinuxCNC

Hi,
I'm a bit desperate. I want to replace my very old pc based linuxcnc with the actual version running on a raspberry pi 5.
I've been trying to get signals to the pin header for a day now.
First of all: Is there a tutorial for raspberry configuration? I found nothing except the general docu and then went from one error message to another.
What I did is:
1. Started Stepconf wizard
2. Replaced parallel port Pins with hal_gpioxxx, see attached hal file

File Attachment:

File Name: AndyCNC.hal
File Size:3 KB

When I start this Setup following error occurs:

File Attachment:

File Name: linuxcnc_report.txt
File Size:6 KB

This was my try to set the PINs:

halcmd: loadrt hal_gpio inputs=PIN3,PIN5,PIN7 outputs=PIN5,PIN6,PIN9,PIN10,PIN11,PIN17,PIN22,PIN27
Note: Using POSIX realtime
The GPIO line PIN3 can not be found
hal_gpio: rtapi_app_main: Operation not permitted (-1)
<stdin>:12: waitpid failed /usr/bin/rtapi_app hal_gpio
<stdin>:12: /usr/bin/rtapi_app exited without becoming ready
<stdin>:12: insmod for hal_gpio failed, returned -1
halcmd: Note: Using POSIX realtime

Would be nice if onyone could show my where I'm wrong.

at a constant spindle speed, as the offset changes with thread

Which LinuxCNC version? Not being able to cut threads would be a huge problem.

In your constant speed example, is there any possibility that what you are seeing is the "virtual compound angle" Q ?
