Thanks For Your reply !
What we have done is copied the profile from the Crealty slicer we didn't do any tweaking to the profile.
You can sea a big quality difference between cura porfile and simplefy3d the only problem is its price 150,- dollar that is a lot of money and you get only a year of updates.
I checked the retraction settings if they are correct whit the Crealty slicer and they are.
there needs to be a lot of tweaking to the profile. spanishcop Please keep us posted on simplify3d !!
