rc.local would work, but not sure it is usable still on Debian, i know Mint stopped using it a while back, but it can still be made to work with a bit of fiddling.

Sometimes it does help, a lot, although only once in my experience, the rest (probably over 10) both sides worked better.
All VFD's i have used have separate ground pins for mains and for motor, probably have some LC filter inside but i never checked, waiting for one of those to die so i can open it.
Another thing i noticed with a cheap 2.2KW HY-whatever VFD was that grounding the motor wires on both sides would make it possible to use it without mains grounding at all, hence the above assumption on LC filtering.

Otherwise in /etc/rc.local above "exit 0": sleep 10 && echo .....

Or "sudo crontab -e": @reboot sleep 10 && echo ......

The sleep is necessary with the orange pi at least.

Here some pic assembled with the case.
Much more space in the cabinet now

ok, probieren wir aus

besten Dank, herzliche Grüsse

 Um einen NPN-Sensor mit einem 7I76-Eingang zu verwenden,
ist ein Pullup-Widerstand erforderlich
(schlagen Sie 1K 1W von +24V zum Sensorausgang vor)

Here's a fair description of whats needed:

guten Tag miteinanderIch versuche mich in LinuxCNC 2.9.3. an der
Einbindung folgender externer Komponenten in die HAL (und/oder INI) meiner CNC Maschine, so zum Beispiel

Werkzeug Längentaster
3D Messtaster (Schnittstelle)
Mindermengenschmierung

In Verwendung mitMesa 7i92Mesa 7i76Das Werkzeug Längentaster Signal liegt auf Kontakt 29 oder Input 14 TB5 der Karte, während /- des NPN 24V Sensors von einem Netzgerät gespiesen werden.Wenn ich den Taster drücke und die LED am Taster selbst ablöscht, erhalte ich in der Halshow keinen Wechsel von Input 29-not auf Input 29. Ich kann somit keine Werkzeug dynamisch ausmessen.Frage:Was mache ich falsch, oder  was muss in der HAL richtig schreiben?Halshow Component Pins:Owner   Type  Dir         Value  Name    36  bit   OUT         FALSE  hm2_7i92.0.7i76.0.0.input-29 ==> probe-delay    36  bit   OUT          TRUE  hm2_7i92.0.7i76.0.0.input-29-not

 

Buy Mesa 7I76 STEP/IO or 7I76U DB25 Daugheter Card
