LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Start with the official raspberry pi image, disable wayland, install the real time kernel and then the linuxcnc packages.

Plasma and Ethercat?

Category: Plasma & Laser

Still seems to far fetched, if it melts if will blow out the nozzle, very quickly, but might be just at the surface ...
Hypertherm, so lends to a lot of trust, although i am leaning to marketing.
I have read everything on Hypertherm, Kjellberg Finsterwalde, Thermal Dynamics, Cebora, Victor (now owner of most of these), etc, and never ever bumped into melting Hafnium, all say eroding, although technically that is melting small parts.
As for "controlled current ramps", it does help longevity, but older stuff never had that, just a relay switching on and off a huge transformer.
Some have another transformer to cut the cutting current for a short period while the pilot arc is on till it detects current flowing, then turns on the relay, Thermal Dynamic Pak90 has such a system, and uses high voltage pilot at 50Hz or 60Hz, not HF.

We should move this discussion somewhere else, any ideas welcome.

[OT] Frage zu Spannzangen und Eigenbau-Werkzeug

Category: Deutsch

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?

Was ist das F66? Wenn ich das bei Google eingebe, kommen nur Autos. (Ich glaube nicht, dass du das gemeint hast).

Die Spindelaufnahme ist noch nicht 100% definiert, wird aber wahrscheinlich so etwas werden:

Real-Time Kernel with Orange Pi 4 LTS

Category: General LinuxCNC Questions

@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.
