Maximum retraction speed?

Hello all,

What is the maximum retraction speed of the printer? Also what’s the maximum retraction distance before clogging is a large risk?

I’ve got almost everything perfect but I’m still getting the odd blob and zit so I would like to fix it.


I have mine set for
Retraction 4mm
Speed 110mm
PLA 190C
Sorry I don’t print ABS but I have seen 220C is a good temp
