Hi folks,
I have Ultimaker Extended 3 and I want to control my printer with Raspberry Pi 4B. I downloaded OctoPi 0.17.0.
I managed to reach interface of OctoPrint but somehow my printer doesn't connect with OctoPrint. When I've tried to manually connection, I'm taking that kind of error. Do you have anybody that can help me?
Connecting to: dev/ttyAMA0Changing monitoring state from "Offline" to "Opening serial port"Connected to: Serial<id=0xad1e9cb0, open=True>(port='dev/ttyAMA0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitorStarting baud rate detection...Changing monitoring state from "Opening serial port" to "Detecting baudrate"Trying baudrate: 115200Could not write anything to the serial port in 5 tries, something appears to be wrong with the printer communicationChanging monitoring state from "Detecting baudrate" to "Offline (Error: Could not write to serial port)"Connection closed, closing down monitor Closing down send loop

I've tried to give authorisation with
sudo usermod -a -G dialout pi
sudo chmod a+rw /dev/ttyACM0
I'm pretty sure my printer's port is ttyACM0 because there is nothing like ttyUSB when I'm searching.
This is my last 20 line of dmesg
