I think its unlikely that you would need so much DPLL pre-trigger so I don't think
increasinh this timr to 250 usec is going to help

I would check hm2_7i76e.0.packet-error-total to see if you have dropped any packets

You might try plotting the following error and perhaps tuning by adding a little
FF2 (say .0003 to start) to the PID loop (using the calibrate menu so you can do this live)

Also, I considered using the directions at: forum.linuxcnc.org/9-installing-linuxcnc...tall-rtai-got-errors

but when I look at the directory linuxcnc.org/dists/bookworm/2.9-rt/binary-amd64/

I don't see a 2.9.4 version, so I wonder if that is the source of the problems (or maybe just completely unrelated).

I tried without removing any of the "rt" "linux_image" s . Again, there was no "non-rt" linux-images.

Also, I tried without linuxcnc-install.sh first (you'll see why later).

When I ran sudo apt-get update, it ran fine, but when I ran sudo apt-get install linuxcnc, it gives the error:

Package linuxcnc is not available, but is referred to by another pacakge. This may mean that the package is missing, has been obsoleted, or is only availabe from another source.

E: Package 'linuxcnc has no installation candidate.

So then I went back and did sudo ./linuxcnc-install.sh

I got the error:

E: Conflicting values set for option Signed-by regarding source httyps://www.linuxcnc.or/ bookworm: /etc/apt/trusted.gpg.d/linuxcnc.gpg.key.binary.gpg != /usr/share/keyrings/linuxcnc.gpg
E: The list of sources could not be read.

You might want to consider installating the docs package for your language
And also the linux-cnc-uspace-dev package
sudo apt-get install linuxcnc-doc-[en/'fr/de/ja/es/ru/da/hu/s1]
sudo apt-get install linux-dev

Next I ran sudo apt-get update and I get the following error again:

E: Conflicting values set for option Signed-by regarding source httyps://www.linuxcnc.or/ bookworm: /etc/apt/trusted.gpg.d/linuxcnc.gpg.key.binary.gpg != /usr/share/keyrings/linuxcnc.gpg

I can clear this error by commenting out both lines in /etc/apt/sources.list.d/linuxcnc.list . (I think this basically partially undoes the linuxcnc-install.sh . )

After that I'm back to having no install canidate for linuxcnc.

So, I did skip 7.1.3, which may be my problem, but none of the packages I have installed are "non-rt", so I don't know which to remove.

Also, I don't know if there is a step that tells the system where to get "linuxcnc". I suspect the linuxcnc-install.sh is supposed to provide it, but it just causes problems with apt.

Hello again!
Today, I tried my machine out with a new .ngc file for a part to mill, and while testing in the air, although with reduced G0 to 5500mm/min, I got the "motor-0-position error" again.
So, I changed the setp hm2_7i76e.0.dpll.01.timer-us -200 to 250. The next run comes without the error. But i am sceptical - how far can I go with this or should I change othere settings too?
WHat about the min Ferror - i had 0,01mm is this too much, should i go to 0,1?

Thanks for any answer!
Kind regards,
Hanno

Problem gelöst - dank TooTall18T's neuer Version 5.01 der Probe Basic WErkzeugwechselroutine. Siehe auch

Danke!

Copying the velocity FF command from the comp file to the XML file significantly reduces following error to a ramp. I haven't really tuned the drive yet. If anyone has found an auto-tune button, please let me know.

.comp
  drv_target_velocity = (int32_t) (velocity_cmd * velo_scale);

.xml
<pdoEntry idx="60B1" subIdx="00" bitLen="32" halPin="target-velocity" halType="s32"/>

Hello TooTall18T!
I tested the V.5.01 and voila - it works as it should and the Feed Override Slider is active again! Thank you for detecting that problem in your routine and fixing it finally! You are my hero, my machine is now ready for the first chips. (not really, but mainly)
Thanks a lot,
Hanno
