Thank you Stefan,

You have bought a pack E, so you have received :

  • One PCB with all electronic components already soldered, GRBL already installed.
  • Few jumpers to change microsteps resolution if you want (they are under the drivers)

It’s very important to follow carefully the chapter “Installation in K40” in this article :  link

Then you’ll have to install & configure Lightburn : link

After that, you will have to follow the steps for the first use in the K40 : link

Finally, you’ll be able to connect your ESP32 to your wifi network following instructions here : Link

Please take the time to read all instructions to avoid damaging your K40 or your new shield 🙂

Thank you very much again !
