I still have to port it to the main branch, but it already works in dev.

Do you have an example config for this setup? I just installed the dev branch and wanted to try out the modbus spindle control with buttons like that video but I wasn't sure what plugin to use and how to connect the hal. Dev branch is looking really good btw, I am really excited to try out the remote devices over rs422, I was thinking of building a plasma controller for a THC to start with

zum rumspielen ist denke ich, ist der TangNano9k ein guter einstieg,
im prinzip geht es auch günstiger, ber dann ist man extrem limitiert.

Aber es kommt immer drauf an was du machen möchtest, es sind halt nur dev-boards.

Halt stop, zurück :)

den TangNano9K kann man nicht vom RPI4 aus programmieren, dafür braucht man einen PC.

Was ginge den vom rpi4?

Ich hab ein rpi4 mit 7i92 an einer emco vmc100.
Läuft super.
Latenz ist aber so lala.. daher wollte ich den für nen tischaufbau nutzen km sachen zu erproben.

An die vmc100 kommt n optiplex 3050m.
