What is the problem?
About a month ago I had a print going that messed up, blob on the print head and during removal, I broke the thermistor wire (it was heated an on to try and melt but I did not wait long enough.
What did you already try to solve it?
I replaced the entire hot end assembly, re calibrated and got back in business, but my octoprint would not connect. SD card prints worked flawlessly.
Mind you I have a MK3s working flawlessly with the same setup with octoprint sitting next to the MMU2s/MK3s unit I can not connect.
Using a laptop and usb cable, I updated to the current firmware ... so USB port seems to work?
Formatted the micro sd card, downloaded latest octopi .17, inserted into the Pi and after a minute or 2 I was in octoprint setting up the profile.
EDIT: setup the profile using 5 extruders and shared nozzle as seen in another post
With the serial port and baud rate set, it would not connect, when i set it to auto it connected and said operational, when I went to send a print, it never asked for filament and after 30 seconds timed out.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
one clip from the terminal:
Changing monitoring state from "Offline" to "Detecting serial port"
Serial port list: ['/dev/ttyACM0']

logs removed because it has more than 2 links in it, will post in reply
