Ultimaker 2+ Extended Nozzle Temp Drops After Mid-Print Filament Change


Recommended Posts

Posted · Ultimaker 2+ Extended Nozzle Temp Drops After Mid-Print Filament Change

Title says it all.


Filament change is initiated, the current material will retract, I insert the new material and select Ready to advance it. when it starts coming out of the nozzle, I press the Ready button again, and when that happens, the print will start back up as it should, but the nozzle stops heating. The nozzle temp will just start dropping. This prevents the material from coming out since it's solidifying now.

I hope this is an easy solution but every time I google the issue, I get very generic 'solutions' since the search terms are generic phrases/words.

I've tried OctoPrint mid-print filament change, using Cura's Post-Processing Plugin, and manually pausing my machine to change filament. This tells me it's a firmware (machine specific) thing and not Cura itself.


The only way I've gotten it to 'work' (not really) is that if I'm using Octoprint I can quickly turn back on the nozzle heater after I complete the filament change, so the nozzle temp drops for only a second, but that's not exactly a solution.


Look forward to your help.

        (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
