What is the problem?
I’ve had my pi for about 3 years, hooked up to my makerbot. Installed octoprint and basically have had zero issues. On Saturday things started acting wonky, first I had a sudden loss of communications between octoprint and the printer, the fix I found was to change the Gcode flavor in GPX from Makerbot to RepRap, I had never changed that setting since originally installing OctoPrint. I made the change and suddenly things started working again.
It printed fine until Sunday morning or so where i again lost complete access to the printer remotely. I found that most of my Version of OctoPrint, Octopi and pip all required updates. I updated them and the problem continued
I bypassed the pi completely and plugged my laptop directly into the printer and had full comms (verifying usb on the printer is good). I stepped back and swapped to all 4 ports on the pi, no coms. My webcam is working through my Pi and I am receiving temperature readings from my printer, so some kind of communication is happening however when I click Print I get a serial error.
TL:TR So I can talk with the pi enough to interface with octoprint, I can receive webcam and temp updates like normal, however once I click Print I get a serial error and everything shuts down.
What did you already try to solve it?
Upgraded Versions of All Programs to there latest version, No Change
Hardwired Laptop to Printer, Bypassing Pi and OctoPrint and have communication (This verified USB on Prtinter is working)
Changed Cable from Printer to Raspberry Pi, no Change
Changed Ports on Raspberry Pi, No Change
Installed Fresh copy of OctoPrint, Didn't Restore from backup, set up parameters manually, no change
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
