Can you see via telnet what is going on?

Do you have the same issue with this build? https://github.com/probonopd/WirelessPrinting/releases/tag/bad8e51

Nothing unusual.

Yes, same issue.

It is necessary to power on the PC? i think if my mac goes to sleepmode, the print is stoping.

Ok, strange. If i open an terminal with telnet and my macbook goes to sleep mode or i hit the button "go to sleep mode", the printer stops the print. If i start my mac again, the print go on.

Not for normal operation. With telnet, maybe.

Ender2, SKR mini E3 v1.2 with Marlin 2.0.4.4

[cpeuschel]

maybe its not an issue

[probonopd]

Could you try e.g., on the Ender-2 with Marlin 1.x?

[cpeuschel]

Sure. It will take some minutes :D

[cpeuschel]

I think i cant install marlin 1.x on the skr mini e3

[probonopd]

ah, you don't have the original Ender-2 board left?

[cpeuschel]

i dont think so. There no rx + tx pins left

With telnet connection it took 10 secounds to write "sending"

With telnet connection and sleep mode by mac it took over one minute.

I have modify follow code:

inline void telnetSend(const String line) {
  Serial.println("\n sending");
  if (serverClient && serverClient.connected())     // send data to telnet client if connected
  {
    Serial.println("client available");
    serverClient.println(line);
    Serial.println("sending");
  } else {
    Serial.println("Client not available");
  }
}
