Heating Cycle

My apologies if this is covered elsewhere, but all the search terms I can think of are so generic I can't find anything that covers this.


I'm now on the latest but one version of Cura 4.6.0 and use a generic Prusa i3.


One thing I find very frustrating, is that Cura heats the bed, and only then heats the extruder, rather than doing this simultaneously. Manually preheating is a chore I would prefer to avoid.


This can be  a huge timewaster on small parts, add in several minutes to the warm up time (I have both and under-insulated bed and use a silicon sleeve on my extruder block - before adding these it was even worse!)


When printing a series of small parts or fine tuning z-height after a nozzle change the extruder inevitably cools significantly even if I am quick so the bed only needs to warm a few degrees.


I have searched in vain for somewhere to change the startup sequence, but it seems to be hard-wired into the i3 profile in Cura.


Am I mistaken? Is it possible to change this and, even so, is it worth changing the default to simultaneous warm up of extruder and bed?

      • 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
