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.

you shush

The best thing to do is to sit back and wait for a reply that he has fixed it

There is also "psng" and my own fork of psng here:
github.com/andypugh/probe-screen-ng
(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.

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?

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
When I start this Setup following error occurs:  

This was my try to set the PINs:
Would be nice if onyone could show my where I'm wrong.

It also causes errors even
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 ?

Can _what_ be run on Linux?

Can you explain what you want to do?

Check and lower the P value in the ini.

Estop fixed, my mistake.
But as soon as i enable, the servos howl like mad, even though i had just tuned them perfectly. Hmmmmmm.

Have you raised an issue on the LinuxCNC github page?

While I've raised a couple issues in the past, I am reluctant to directly engage on GH because I don't speak 'computer' fluently.  I can describe an issue in laymans terms, but as soon as any discussion moves towards code-type testing & solutions I'm lost.  My typical modus operandi is to prompt enough discussion on this forum that somone clever takes up the torch over on GH.

I'll raise one now, thanks for the reminder about it.

EDIT: github.com/LinuxCNC/linuxcnc/issues/3455

I have no working config.
ill figure it out after lunch.
