SD card upload #4

Open ErikDeBruijn opened 13 years ago

There currently is no support for uploading files to the SD card during printing for untethered printing. This would be very useful to have. Just printing a file preloaded on the SD card would also be a big bonus, especially with an LCD, so you can have a fully standalone machine.

going the sd card route is a detour, I would think: if you use a at90USBkey instead of a arduino mega, then you can let it function as a mass storage device, store your g-code file on the onboard memory (only a few Mb, but much more than a stock arduino). In effect this means that you connect to the host computer with usb (no serial bottleneck), upload your g-code, and disconnect again. From there you start the build with the lcd-interface?

The downside is that this USB key is in short supply and has no nice 1/10 pin layout and you need some more changes to fully support it.

Thanks JelleB, for the suggestion. I'll definitely look into this! I had other plans for giving it more connectivity (running Linux), but this seems like a viable path too...
