What is the problem?
My FLSun SR printer is not connecting to Octoprint. OTG cable is plugged in using the cable sent with the printer.
What did you already try to solve it?
I read online that the baud rate needed to be 256000 so that's been tried, still no love.
Changed connection from Auto/Auto to Auto/256000
Verified OTG with usb thumb drive
Of course, reboot everything several times.
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
No
