    Funny... or one could just read every post in this thread

    You are very correct in dealing with this from scratch. That is the very reason for this thread.
    I am a mechanical type with a little too much knowledge of the other disciplines.

    Have you tried putting the current bootloader on a 3rd party Nano?

    I watched the routine and I understand it...
    Basically, configure a NANO as an ISP and load the current Arduino bootloader onto a properly connected NANO.
    Does that not solve the CH340 issue?

    I also noted a few pads on the NANO on the USB CH340 chip side. Any idea what those selectors select?

    I'm buying NANOs from all over China to get a good idea of variation.
    I have seen people reload the bootloader to get access to the current bootloader in the Arduino IDE.
    I didn't have to do anything with regard to loading a special CH340 driver in Windows 10.

    Once I get a decent stock of Nanos, I'll see if I can do this.

    How many do I put you down for, John?

    "Basically, configure a NANO as an ISP and load the current Arduino bootloader onto a properly connected NANO."

    That is above my pay grade!!

    My nano's don't appear to have any pads on either side. They are "Elegoo" brand.

    What's not ok about using the "Old Bootloader"? Why bother to burn the current bootloader?

    Just a side hobby.

    This guy does well in explaining the process. It was a couple of these that made this whole thing make sense.

    Nano Pads

    These are often used for selectable options by either jumper or pull-up resistor.
    I'll have to ohm out where in the circuit they reside.

    I have 1 blank board, 7 stuffed boards, and a complete unit. ...save the one going to Alex.

    I've put the first ReCube up on eBay.

    More to follow as I start receiving more Nano's.

    Let me know what you think of the ad.

    The ad looks very good - clear and complete description IMO. Very good deal!

    Oh, and my nano does have those pads - I just didn't know where to look...

    Perhaps words like Hack Free Filament or something like that in the title would help too? Dunno if ebay still focuses searches on keywords on the titles...

    Once you find haxtom, I think you're there!

    This rarely happens... Today I received a second NANO from a previous order for only one Nano. Its got all the pins soldered in it making it hard to use for the ReCube.
    I'll add it to the Arduino development collection.

    The first ReCube Light Cubify Cartridge Recharge Wand sold yesterday.
    More will be coming as Nano's arrive.

    Need more eyes on the ad though. I'll see what I need some changes to make it more visible.
