I've been trying to setup my ender 3 pro printer with octopi but without luck so far.
What is the problem
The problem is that I can't connect to my printer to octopi, when im trying to connect on octopi.local I will get the following error message "No more candidates to test, and no working port/baudrate combination detected"
What did you already try to solve it?
What I've been trying so far is that I tried multiple cables without luck
@Ewald_Ikemann why? I see no reason that the OP must use Marlin. If they would like to use Klipper, then they may do so.
@cupsen12 it looks like you need to build & flash the latest version of Klipper to your printer, as you have a mismatch between the host (Pi) and MCU (printer). The instructions for that are in the same docs that I linked before, here.
