PanelDue USB Host



  • As main electronics is usually somewhere inside printer and not exposed to user, PanelDue with LCD is something to interact with.
    It would be nice to have option to load gcode file from USB thumb (save it to internal SD card if needed, mostly for cache purpose).

    I know, that there is SD card slot, but SD card is fragile, small and USB drive is something more common. Not every computer have SD card reader, but almost every computer have USB port.

    Neither the Duet nor the PanelDue has USB host capability in the microcontroller, which would be needed to support USB storage. The standard way to manage files on the Duet is via the web interface. If you want to back up gcode files to a USB drive, why not do it on the PC?

    What a pity. Ok, never mind 🙂

    The reason wasn't to backup files, but to transfer them to Duet some other way than SD card or Web interface.

    It's like when you have your files to print with desktop "paper" printer on USB thumb. There is also ability to print them over network and from removable device on printer itself.

    But never mind. When microcontroller can't do that, then I have to deal with it 😉

    I have never used USB thumb drives to transfer files to a paper printer, and I can't think of any reason why I might want I do so. My paper and 3D printers are on the network so that I don't need to do that. Perhaps you have come from the older generation of 3D printers where transferring the files physically on an SD card was the most practical way to get them to the printer, and you haven't got used to using the web interface yet?

    I guess if you take your printer to a different location where you are unable to connect to a network, then you might want to transfer files to it via removable media.

    "older generation of 3D printers"… that's a fancy name. Maybe I'll start to using that. 😉
    And yes, you are right. In fact I'm still used to using printer directly connected to computer. Even SD card is in my eyes cool think for printing gcode files.

    That's one of the reasons, yes. Or some place, where is network unusable, like conference or expo, where wifi is so jammed, like there is no network at all.
    But yeah, in these cases is SD card good option.

    I've noticed, that when smoothieware is connected to the computer, sd card is mounted as removable drive. For uploading file is it slow, but it's great for configuration purpose. Any plans with that?
    Maybe it's oldschool too 🙂

    The problem with that approach is that you can either mount the SD card as a removable drive, or the electronics can access files on it; but not both at the same time. Smoothieboard users sometimes get into a mess because they forget which mode it is in.

    When moving a Duet WiFi to a location where wifi is not available, you can configure the Duet to provide an access point, so that you don't need to connect it to another WiFi network.

    Ah, I didn't noticed. It seams that I'm one of those users 🙂
