Creality CP-01 prrinter

What is the problem?

I cannot make a connection from Octoprint to my Creality CP01 printer

What did you already try to solve it?

Tried different cable, tried 5v back-feed cable modification,

Have you tried running in safe mode?

No I'm not sure how that will help

Did running in safe mode solve the problem?

Don't know

Hello everybody, hope this is legit way to post asking for help.

Has anybody managed to connect a Creality CP-01 to Octoprint ?

When trying to connect I get ;

"Changing monitoring state from "Offline" to "Detecting serial connection"
Performing autodetection with 0 port/baudrate candidates:
Changing monitoring state from "Detecting serial connection" to "Error: No more candidates to test, and no working port/baudrate combination detected."
Changing monitoring state from "Error: No more candidates to test, and no working port/baudrate combination detected." to "Offline (Error: No more candidates to test, and no working port/baudrate combination detected.)"

It seems like the port USB is not detected or that the Creality control board does not get recognised somehow, more likely seems to me that a serial connection over USB is not being detected as no settings are even tried. Only AUTO is available for the port, no other choices. Printer is about 12 months old and works Ok when I put a SD card in it and load from their control panel.

How many cables have you tried? Not all of them work, since they are not all full data cables. Try at least 3, see if they work. You are correct when you say it seems like the creality control board is not recognised by the printer.
