I´m new to simplify3D, and looking for a way to lower the inactive hotend temperature in process settings in a dual extruder to prevent oozing I haven´t found anything.
From the prints I have done, I always found that this causes more issues than it solves. Constantly raising the extruder temperatures up and down creates lots of other print quality issues, since it takes time for this change to happen, and usually it affects the plastic in the nozzle as well. I always found I got far worse prints when trying to cool down and extruder in the middle of the print, so I've just been using the ooze shield which catches the majority of the oozing and also making sure I have a good tool change retraction distance in my settings.
