@PatJac The rk3588 works really well indeed with the 6.1.75 kernel and just the last core isolated. The 6.12 kernel deb files are now uploaded for both boards too. And let us know the result you can get with the RK3399 board please. But likely the results will be better when the LinuxCNC source code will be edited so it'll move the rt task to the isolated core instead of the fixed last core, because the first 2 cores are the faster ones.

Mein "Werkzeug" hat einen Durchmesser von 42 mm (oder etwas mehr) und nein, ich kann es leider nicht kleiner machen.

Das dürfte schwierig werden ER zB hat meines Wissens maximal 36mm (ER50).
Das sind schon eher Dimensionen für Spannzangen der WerkSTÜCK spannung (zB F66).
Auf was für einer Spindelaufnahme soll das denn montiert werden?

During cutting the hafnium is in molten state. Thats why you do controlled current ramps, to try and keep the hafnium steady.

”Most of this wear occurs at the start and stop of a cut when the molten hafnium material quickly heats up and cools down, melting then re-solidifying.”

@Hossein74Majidi That's a pity then that it doesn't work. But now LinuxCNC does work with this image you should be able to use the other kernel with another image which works with LinuxCNC.
To compile your own image with Armbian:
- You'll see in the directory patch/kernel/archive wich kernels (rockchip64) has the patches to add the opi 4
- In the this file you can set the kernel version: config/sources/families/include/rockchip64_common.inc
- The rt patch (except for 6.12) you put in the directory patch/kernel/archive/rockchip64-6.*
- Remove the part from the patch where it adds the "localversion" like you see here under, otherwise you'll get an error the moment it will install the kernel in the image

- In the file below you might want to change the gpu governor to performance (which I didn't):
packages/bsp/rk3399/20-gpu-governor.conf

./compille (optional) EXPERT=yes
If you've done it correctly, after you chose the option that you want to see the kernel config, you'll see the option "Full preemption realtime" in General setup.

Gut, dass ich gefragt habe, denn das zeigt mir, dass ich einiges noch nicht verstanden habe.

Zur Verdeutlichung habe ich mir mal ein Bild im Netz gesucht und versucht, die Teile zu benennen, damit ich weiß, was was ist.
A = Werkzeug (Bohrer etc.)
B = ER-Spannzange
C = ER-Spannmutter
D = ER-Spannfutter
 

Mein "Werkzeug" hat einen Durchmesser von 42 mm (oder etwas mehr) und nein, ich kann es leider nicht kleiner machen.

Warum, möchte man darauf verzichten?

Die Spannzangen in Übergröße würde ich versuchen zu vermeiden.

Das wäre für mich ein wichtiger Aspekt.

roland wrote:

Die Spannmutter und die Spannzange sind ungefähr bündig.

Ok, dann gibt es verschiedene Dinge, kann man da pauschal Vor- und Nachteile der einzelnen Varianten (OZ, ER, ...) benennen?

Das von dir verlinkte Spannzangenfutter ist OZ und somit nicht passend für ER Spannzangen

 

Thanks! I will check this out.

hey there,

i have this problem, that status time is not counting, 
im using fusion 360, it has been counting before

idk if it´s fusion or qtdragon

hope for some advise

merry christmas every one !
 

need more information on your build, what debian version what kernel version etc... the sim here is working as expected so i would assume the issue is a compatibility problem you are experiencing perhaps or maybe the custom_config.yml file needs to be updated.

have you tested using the simulation version of probe basic?
