CR-10 S4, BLTouch

  • Hi everyone,
    I'm installing my BLTouch on my S4 and when it came time to install the firmware with Creality Slicer, I connected the cable but I wasn't give the option to connect to COM3 or any other COM(s), just "AUTO". Anyone run into this problem before and have an idea of how to fix it. I ran through all steps again and I'm at a loss.

    Thank you.

  • @Dalffy windows? when you connect the cord, it probably prompts you to install a driver, which you have to do.
    There should be some "driver" files included on the SD card that you can select.

  • Your operating system may have com3 assigned to another device. Maybe a printer? Go into Windows device manager and release it, if it is.

  • Depending on your operating system, find the device that is using com3 and assign it a new com number. This will make com3 available for the slicer program to assign it to your printer.

    Ie. windows device manager
    A printer may take that port if it’s open when you first
    installed it.
