Looking for some help please.

I have an Ender 3 S1 Pro, I just upgraded to the latest version of Cura, looking to add my printer via the USB-C on the Ender to Cura on my Mac.

 

Ive tried restarting the Printer, closing and reopening Cura, no dice!

 

any help welcome

    Printing over USB is deprecated and no longer supported. It's a remnant from the days when printers had absolutely no brains of their own and had to be told what to do one thing at a time.

     

    It's also a bad idea in general. If your computer crashes or something, then boom, there goes your print.

     

    You should save gcode files to a memory card/USB drive/whatever your printer uses and run it from the printer itself.

    The normal procedure for using the printer is that you slice your model, put the gcode file on an SD card on your computer, then insert the card into the printer and start from the printer's control panel.

     

    You can't update the firmware over USB, you need to put the files on a memory card. There should be instructions included with the firmware files. There should also be acceptably translated English instructions after the Chinese ones.

     

    As for whether you need to update, especially with Creality firmware, the general rule is "if it ain't broke, don't fix it". So unless you experience problems you probably don't need to update the firmware.

     

    I can't speak for the S1 Pro, but it looks pretty similar to the E3V2Neo and E3V3SE so the update process might be equally similar. Here's how you do it for the ones I know:

    1. You need to format a microSD card (4-16GB, if it came with one that should work) as FAT32 with a sector size of 4096 bytes
    2. Copy the firmware file for the screen to the card
    3. Insert it into the screen, turn the printer on, wait for it to update (it'll show you on the screen), then turn the printer off
    4. Connect the SD card to your computer again, delete the screen firmware file from it and copy the printer firmware file to it
    5. Insert the card into the printer, turn it on, it should show it's updating then start normally
    6. You can leave the printer firmware file on the card if you want, but probably better if you delete it

    Of course, this wouldn't be Creality if there weren't some things to bear in mind. This is the part where you should stop reading because you shouldn't worry about it, but I write for my own amusement and hopefully that of other experienced users on the forums.

    • I don't know what happens if you try using a sector size other than 4096 bytes, but any cards more than 16GB can't be formatted with sectors that small.
      • If you need to buy a memory card, and you don't have a stash of them like me from various gadgets, unless you want to order one direct from China it'll probably cost you the same as a 64GB card.
      • I haven't tried using a bigger card but creating a single 16GB partition, but that's a bit beyond the average user (no offence).
    • Both the E3V2Neo and E3V3SE come with a memory card and a USB card reader. I've been through one E3V2Neo and three E3V3SE's and the longest any of the included cards has worked was 3 weeks.
      • The median is two weeks.
      • The card readers tend to not even last that long.
      • If you don't have other cards or card readers, use the ones that came with it. If/when they fail it's not a catastrophic failure, you'll just get errors copying files over, or the printer and computer won't realise a card is connected, or something like that.
    • When the instructions for the E3V2Neo say to insert the memory card into the back of the screen, they mean it literally. You need to unscrew the back cover and there's a microSD slot on the back of the motherboard.
      • On the E3V3SE there's a slot in the side of the screen unit.
    • The E3V2Neo uses microSD cards for its primary storage. The E3V3SE uses a full size SD card, but you still need a microSD card to update the screen.
      • Luckily I found an 8GB microSD card laying around and about a million micro-full size adapters so I just use that.
    • The printer will consider any firmware file which has a different filename to the previous one it installed an upgrade.
      • Actually great for recovery if the update process %#(^s up somehow.
      • Also good for downgrading if an "update" turns to be more of a "downdate".
      • The screen is actually smarter than the printer in this regard, it will only update to newer versions.
