Being new to 3d printing, Octoprint AND a Linux environment, I can't get Octoprint (running in web browser on a Windows 10 system) to connect to my Prusa i3 Mk3S (firmware version 3.8.0).
I have spent a good bit of time trying to get this to work before posting, without luck. Here's what I've done:
- installed my RaspberryPi Zero W into my printer. The micro SD card has been flashed with OctoPi 0.16.0. Turned my printer on, and set the RPi setting for my printer to On. Using PuTTY, I connected to it wirelessly, and using my browser (Firefox, most recent version), I can connect to the server as well. I ran the following commands to prepare to install PrusaMeshMap.
/home/pi/oprint/bin/pip --no-cache-dir install 'numpy<1.17' /home/pi/oprint/bin/pip --no-cache-dir install 'matplotlib<3.0'
I realize these are installing older versions, but PrusaMeshMap can't be installed with the new versions.
PMM installed fine, and it shows up in the Octoprint browser window, but I can't connect to the printer to use it. I also connected with the serial cable that came with my printer. The printer shows as Offline on the left side of the Octoprint window, and all my attempts to manually configure the serial port have not worked either. I tried baud rates, tried to add a port manually since the only option in the drop down menu is Auto, which didn't work, but I don't know what kind of port address it wants for the USB slot I plugged it into. I have tried suggestions in other posts on here, but nothing has worked. The log was nothing but saying it was switching from Connecting to Offline, and that I should try to configure the serial port manually.
I'm completely stumped. Any help would be greatly appreciated.
