Marlin - Short file name from a Long file name

Posted · Marlin - Short file name from a Long file name

I'm posting this here because some of you folks are really good with software.

 

I've been working on an application and one of the features I'd like to add is to be able to call a 2nd gcode file from within a 1st gcode file.  M32 works but requires the 8.3 filename to be written on the line in the 1st gcode file.

I've posted on the RepRap Marlin forum but I thought I'd ask here as well...Is there a way to anticipate how a long file name will be truncated to an 8.3 filename by a printer?

 

As an example, if I copy "B.gcode" to an SD card, stick it in the printer, and query with M20 I get back "B2726~1.GCO".  Then I have to go back into my gcode file and alter my line to M32 S????? B2726~1.GCO.  It's a clumsy way to accomplish what I'm trying to do.  A user would probably find it daunting if not impossible.  If someone could point me in the right direction I'd appreciate it.

 

Thanks,

Greg

    I get to pull this out of my "Things I never knew" file (it's still over a yottabyte) and put it in the "Well now I know" file.

     

    Ta-Daaa...🍺

    The operating system in the computer assigns the 8.3 file name to any file.  The printer just pulls it out and displays it.

     

    This was also from the reading assignment.  I think it stays in the "Things I don't understand" file.

    "... followed by 4 hexadecimal digits derived from an undocumented hash of the filename."

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
