Cannot control printer, raspberry pi image

in General
Hello, i just installed the raspberry Pi Image with repetier server, tested on a Pi 3b and a early model A.
Both with the same problem, serial port is opened, but no communication happens.
Works fine on windows with the same settings.
Using Repetier Firmware, baud rate 115200
Printer is connected to server, but I cannot control it
Here is the console output

    Did you set firmware to Repetier-Firmware? I see it starts with communication but the second command here seems to cause an error and then it stops. Maybe that prevents full correction.

    Yes, repetier firmware is set, I want to try to "adduser repetierserver", how do I quit the server frontend and access the raspberry console?
  • RepetierRepetier
    To access console you jusr login using a ssh client like putty with login pi and password raspberry. But that is not the problem.

    is coming from firmware so it has a connection at startup. Are you sure connection does not work? You could enable logging to show a complete log, but I see here

    So after resend it took 10 minutes to get the next communication error. Since timeout is 30 seconds it seems that in between there was some communication. So it looks more there are communication errors.

    Is the baud rate correct? If you have 250000 it will connect also with 230400 but with lots of errors.

    It's working now. I had strange communication errors on due programming port. Switching to native port solved the error. Time to purchase pro version! Thanks for your great software
