Does Marlin change the material-settings definitely on Ultimaker 2+?


Recommended Posts

Posted · Does Marlin change the material-settings definitely on Ultimaker 2+?

I can find a lot of information about Marlin, but can't find this specific question, so maybe someone can help me out.

 

I consider to change the g-code flavor from ultimaker2 to Marlin because I want to have a higher temperature for the first layer for one print. The printer warns that this will override the machine settings (for the materials). This is fine for this print, but does it change the material setting only for this print, or is the change definitely on the machine? When I make an other print after this one with flavor ultimaker2 (with no material setting in the g-code) does the printer uses it's original setting of the loaded material, or does it use the material settings from the latest print? In other words, is the change in the material-settings with the Marlin flavor definite, or only for the print concerning the g-code?

 

I think I asked the same question in thee different ways in the text above 🙂 But maybe I don't know enough about this and one question leads to another answer. There is probably a lot to learn for me still 🙂

    It does not actually "override" the configured materials, it just ignores the material that is selected on the printer. The material configuration on the printer (from the "material" menu) can not be changed with gcode commands - so all-clear on this topic (IMHO).

     

    On the other hand... all (other) Marlin settings are "sticky" and stay active until the next explicit change. Not all of them are reset at the beginning of a print. This applies (e.g.) for acceleration settings and speed factors.

    That's why it's generally a good idea to reboot the printer between prints with different gcode flavors.

    thanks for this clear answer! By rebooting you mean switching the power off an on with the switch on the back?

    Yes, that's the easiest way.

    As an alternative one could add M501 to the very end of any gcode file. For example by adding it to the end g-code in Cura. This would fulfill the same purpose.

      • 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
