A friend of mine had a Creality CR10 V2 which he purchased some time ago. Evidently it had a bad board in it and he received a replacement but never got around to installing it.

I now have this printer and have replaced the board in it. I have tested the movement along each axis and tested the extrusion. Everything looks to me like it should be ready to go, but I haven’t been able to get it to recognize when an SD card is inserted or when I have a computer connected to it.

I’m a 3d printing newbie and I’m not sure where to go from here. Is it me? Am I doing something wrong? Or is it the printer?

Any advice or guidance on this would be appreciated.

Thanks!

    I don’t have this printer, but the Ender 3 1st Gen. So here are some suggestions for things, I’ve noticed on mine.

    • NTFS doesn’t work. So did you format the SD card with FAT32?
    • Is your SD card maybe too big and did you try smaller cards, with 4GB capacity for example?
    • Depending on your PC and the Mainboard of the CR10 you might need an FTDI driver to get it work. Did you check, if your OS recognises the printer in the device manager (Windows) or with lsusb (Linux)?

      Sorry for the delayed response. I’ve been out of town. Just got back.

      I’ll double check, but I’m pretty sure I used FAT32. I’ll have to check the size of the card, but I’m sure it is more than 4GB.

      The printer was not visible to the OS. I was not familiar with FTDI, but I just looked it up and installed the driver.

      Thanks for your response! I’ll give it another try tonight.

      Still no luck getting it to recognize the laptop or the SD card.

      Here are more details…

      I am using Windows 11. Updates are current. All drivers are current. The printer was not showing up in Device Manager, so I tried installing the FTDI driver as suggested. The printer still does not show up.

      I am using an 8GB SD Card. This is an actual SD card, not a Micro SD with an adapter. This is the smallest SD card I have at the moment. Do I need to go even smaller? Do they still make those? :) The SD card is formatted with FAT32. I even completely reformatted it, just in case. (Full format, not quick)

      The printer still says NO TF CARD after I insert it.

      I am using the Creality slicer, version 4.8.2-254.

      Going to Printer Info, it tells me it is:

      Creality 3D 1.1.6 CR-10 V2

      One thing I have noticed is that if I turn the printer off before unplugging the USB cable, it appears to be getting partial power from the USB port. The screen will flicker until I unplug the USB cable.

      As always, any guidance you can give me is greatly appreciated.

      It still requires USB connection. OP should also check if baud rate is set correctly

          When you connect printer to PC using USB cable you need (assuming you have windows):

          1. Driver for usb serial port(might be already installed, but check device manager. Look for guides how to install Arduino USB driver or maybe you can just install Arduino IDE which is not bad to have anyway
          2. Software to controll printer (pronterface, cura, etc)

          In software like pronterface you have to select serial port (1.) and correct baudrate. Baudrate is set in your firmware, but if you dont know you can try all possible options. Most likely 250000 or 115200

          If its not working try another USB cable. USB cable can be a pain, make sure you dont guide it close to stepper motor wires or some other electrical equipement. Get quality cable and not too long, even if its working it can cause problems.

          Its better to use SD card to avoid USB problems, but SD card must be formated as FAT32 within size limits of your printer board. Just in case, make sure you dont have weird symbols and file name is not too long, use simething like filename.gcode. And again, use quality SD cards.

          Both ways should work, but you can make extra step and get device like raspberry pi and connect it to a printer with usb cable. Raspberry can be connected to your network and you can install software like octoprint (super nice web UI for controlling your printer)
