Stringing retract distance
I have a X5SA and am using the Repetier-host software with slic3r, I have seen tons of video's on stringing and read countless articles on how to adjust and correct for this and have run enough print samples to know that I need to retract 8mm. BUT, nothing and no-one will tell you how to enter the settings into the software. every thing i can find just says to adjust it, but, HOW DO YOU DO IT. all i can find is the backup speed (30%) but not the distance setting. please help.
