Retraction to reduce stringing

I am quite new at SnapMaker and having problems with stringing. Based on testing I did with Gcode files I found on the internet I believe I need to do retraction. That is retract the filament from the nozzle, not retract the whole head. Does Luban have that capability? Or advice on how to get rid of the stringing.

Welcome to the forum.
Retraction is how much it ‘sucks back’ the filament when it stops printing and moves to a new area. SM default is a lot higher than needed for the type of print head it has.
Temp and retraction are main adjustments.
Try a search. Lots of discussion of this on here.
