What is the problem?
Can't get Octopi to talk to my printer. I have a Davinci Pro 1.0
What did you already try to solve it?
Turned off printers Wi-Fi since I thought it may be interfering with the serial port connection. I also created a profile for my printer using "generic" and changed all of the settings to match my printer including build plate size, etc. I tried both the auto and the dev/ttyACMO serial port settings with auto for the baud rate.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
I'm using Octoprint version 1.3.9 on a raspberry pi3. I have successfully connected to Octopi using my browser over its Wi-Fi. The terminal log of the connection process follows:
