Posted · Lift head setting

Hi, been 3D printing for a while and have moved to Cura as my go to slicer, to make my prints better on small layers I have turned on the Lift Head function in order to allow the PLA that I print with to solidify before the next layer, however this then results in ooze from the print head which can lead to under extrusion in subsequent layers. There is the option for retract when Z-hopping but not for lifting the head or are these two things the same, if I enable retract for Z-hop will it view the head lift as a Z-hop and retract the filament?

If this is not the case could this be considered as an option for future versions of Cura, either combining the setting of retract for Z-hop which will also cause a retract on head lift or a bespoke setting for retract on head lift?

    I'm pretty sure it *does* retract when it does "lift head".  But retraction only lasts for a second or so - enough time to jump to a new part of the print.  But lift head will often sit in the air for 3 seconds - plenty of time for a micro sausage to come out and then get deposited on the print when it starts printing again.

     

    The only good solution I've seen is to print a tower next to the part so that the print head can go to the tower and print a little bit to give the print time to cool (just a few seconds is usually enough.  Keep the tower in a position such that when the head goes to it the fans blow on your part (if possible).

     

    Instead of a tower, sometimes I print 2 or 3 or even 7 of the same part.  While printing one parts the other parts all have time to cool.
