no control over printer
i hav connected the printer and the server found him, but when i will start the heating or so on the printer nothing do
Just to be sure connection is really established, the icon for connection gets green and if you go to console you could send M114 and get a response in the log?
Many printers react to commands as soon as usb is connected. Only after they get main power heaters and motors will work. So make sure you have turned it on and it also reaches the printer board.
