Posted · Temperature drop on certain prints

I have a UM2+ running Tinkergnome. I use Cura 15.04 to generate the gcode. I drag the gcode to OctoPrint and it prints.

Some things I print, start fine, but the temperature drops and then nothing comes out after that. But others print out without issue. The process for everything is the same.

What in my process would alter the temp like that? Is there something I can look for in the gcode?

    It's probably related to the "heater timeout" in the firmware. If you print via USB (like Octoprint does), you should disable it on the printer:

    Advanced -> Preferences -> Heater Timeout

    (reduce the value for "Timeout" until it shows "off")

    Currently, it is set to 3 minutes.

    Why would that setting only affect larger prints and not smaller ones?

     

    My suspicion is that this happens, if the command buffer runs empty. And the probability for this is much higher on longer prints with many (and small) line segments.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
