Filament retract during "Lift Head" for "Minimum Layer Time" in Cooling

· Filament retract during "Lift Head" for "Minimum Layer Time" in Cooling
In 5.0 and 5.1 you get something like this:
G1 F1500 X106.692 Y105.679 E230.0867 ;> Last extrusion
G0 F9000 X106.692 Y106.2
;MESH:NONMESH
G0 F600 X106.692 Y106.2 Z1.04
G0 F9000 X105.87 Y105.87
G0 X105.6 Y105.6
;Small layer, adding delay
G1 F2100 E225.0867 ; > Retract 5.0 if there was no retraction since last extrusion
G0 F9000 X105.6 Y105.6 Z4.04
G0 X119.742 Y119.742
G4 P48796 ; > dwell is dependent on Actual Layer Time, Min Layer time, and Min Speed.
There were a couple of instances in the gcode where there was no retraction within the "Small layer, adding delay" section. In all of those cases there was a retraction directly after the last extrusion and so a second retraction wasn't desired.
If you open the gcode file in a text editor and search for "G4" you will see the delay sections. If there is no retraction within the little section then look above for the last extrusion. There should be a retraction right after it.
If your "Max Combing Distance with no Retract" is too high, or if the "Retraction Minimum Travel" is too high then maybe there wouldn't be a retraction(?)

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
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.
