What is the problem?
my ender 3 pro (fw 1.1.6)is not connecting to my pi the problem is with the ender it self so far i could figure out -i only managed to conect to octoprint briefly after many attempts only once -after doing a test print it suddenly lost conection
What did you already try to solve it?
Connecting it to my pc (will conect to the pc -and can confirm i can control it with pronterface)
connecting it tough OTG adapter with my phone works (after i restart the printer with the cable pluged in )
to rule out a bad cable (the cable is new)
so far is i could find out the problem is at my printers end
i can confirm it will see a USB port when powered trough a cable only when the printer is powerd off
i managed to conect octoprint briefly but how i did this i have no clue
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
