Describe your issue:

Hi, I have a Flashforge Creator 3 that I have gutted and started the conversion to klipper.

It has a camera with 5x wires as pictured. The larger black wire on the left is the shields ground, I assume the red and black on the right are 5vdc. Flashforge bricked this printer with a firmware update sometime ago after the warranty expired and immediately wanted me to buy a motherboard to fix a firmware break.

I am not a camera expert, so if anyone know how to figure it out I would appreciate it. I am assuming it just plug into USB becasue of the AU3841 chip, but I am not sure, so I am asking. Pictures attached.

Thank you,

Would it be safe to assume that if Pin 1 (red) is denoted as 5v, and pin 4 (white) is denoted as ground, then would Pint 2 (black) be Data-, and Pin 3 be Data+?

Thanks,

In the first picture: Did you made the plug yourself or was it delivered that way?

The connectors appear to be not completely in the socket.

Get the datasheet and measure / trace the connector pins to the relevant pins on the AU chip.
(or make your life easier and ditch the crap, since you anyway do not know if you get it to run under Linux)

Never assume! You need to know, what you are planning to do… else you fry your electronics

One question first, did you get Klipper running on your Flashforge Creator 3? For me, the camera would come later.

Probably, but again, don’t guess! You need to know. Measuring is the way to go, if you don’t have any schematics.

I assume the red and black on the right are 5vdc.

Why not measuring?

My bit of advice to you would be, take your time and make a good plan.

Good luck, hcet14

I don’t think so.

Do you have the schematics of the printer board?

If not, scary.

Just have a look at that over 200 pin Nuvoton chip. Not supported by Klipper.

I don’t think you’ll get any support from flashforge.com, they just sell! If you want to reuse the printer HW, you’ll need a new concept.

Oh, I forgot. I downloaded the FW.
download center 3d printer software (flashforge.com)
No clue which FW that printer is running.

Sorry, been on a bit of a technology detox. Necessary every once and awhile. Making some headroom. I am almost to the config fine-tuning. It loads, just not everything is reference properly yet, and for my conversion the back of the bed will not be printable, but for my uses that is ok.

Yes, just like the other FF garbage, lol.
