write to ulticontroler's SD from inside cura

Recommended Posts

not sure it this is Cura related or firmware. it probably requires collaboration from both sides, but it would be soooo cool :

the hability to save the Gcode that cura just generated to the SD card that is inserted in the UltiController.

that would allow to have the advantages of printing from SD without the hassle of mounting and dismounting the card from UMO to computer and back.

it probably requires more work from the firmware side than from Cura's, as from cura's point of view, that's not different from direct printing, just need to provide a filename and that's it. just send Gcode through USB.

what do you think ? wouldn't this be usefull ?

The USB connection is an USB-Serial connection. (Translation: SD as an USB storage device is impossible with the current hardware setup)

While there is actually code in place to send the GCode trough the USB-Serial to the SD card, this takes almost as much time as actually printing the file. So the added value is not that high.

You could try this custom firmware: https://github.com/ErwinRieger/Ultimaker2Marlin-USBPrint. With it you can store or print your Cura generated UltiGCode through USB on your UM2.

But note: there is no cura integration (yet ;-)), you have to use a commandline utility to download/print your gcode: https://github.com/ErwinRieger/Ultimaker2Marlin-USBPrint/wiki/UltiPrint.py-Utility.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
