Hi everyone,

i have created a fork of the UM2Marlin firmware on github.

The modifications i have done allows one to store and print "UltiGCode" files to the Ultimaker 2 over the USB port.

Maybe this is useful/interesting for someone...

The work is not fully done, the missing cleanup and documentation as usual - but it works.

It is based on the original Ultimaker2Marlin firmware 14.11-RC8.

There is a quick'dirty python commandline script to download and print UltiGCode files to the UM2, too.

Here is the link to the repository: https://github.com/ErwinRieger/Ultimaker2Marlin-USBPrint

Link to the documentation: https://github.com/ErwinRieger/Ultimaker2Marlin-USBPrint/wiki

Here is the download link: https://github.com/ErwinRieger/Ultimaker2Marlin-USBPrint/releases/tag/14.11-RC8-UP1

Regards, ERRI

    Hello,

    yes, in the first place it allows me to:

     

    • store UltiGCode printfiles on the SD for later manual print, or
    • download and "remote - print" a file immediately, or
    • start the print of a file on SD remotely,

    without touching the SD card in the UM2. That a my current usage scenarios.

    Other possible (future) uses are direct print over USB from Cura or wireless print with OctoPrint - if they were modified accordingly.

     

    Regards, ERRI

    Hello,

    please note, that the "sending side" (cura, octoprint, printrun, doodle3d and so on) must be able to pass through the gcode comments that are part of a UltiGCode file.

    Cura can't do this, and printrun strips theese comments :-( Don't know about octoprint or doodle3d...

    If you want to start printing over USB, a new custom command "M623 <file>" has to be sent. None of the said tools know this command, yet. As far as i know, this should be easy to configure with octoprint.

    That's the reason i hacked my own little utility for usb-download and -print: ultiprint.py.

    Regards
