Stringing issue with ColorFabb PLA Semi-matt white
I really love this material (ColorFabb PLA semi-matte white) but i'm having stringing issues.
Prusaslider has a specific profile for this filament (ColorFabb PLA-PHA), but it doesn't work well.
I did 5 stringing tests, changing the hot-end temperature and some changes in retraction parameter
From left to right (see picture)
Printing at 0.15 (detail)
1) Default ColorFabb PLA-PHA profile - temperature 215-215 - retraction 3.2 (default)
2) temperature 215-195 - retraction 3.2
3) temperature 215-190 - retraction 3.2
4) temperature 215-190 - retraction 4.2
5) temperature 215-190 - retraction 6.0
Lowering temperature produces better printing results (ColorFabb say min195-max220), while increasing retraction affects less.
I specify that i have no particular problems with other filaments (with Prusament no stringing at all, or very minimal).
I have some questions:
1) How far can I safely increase the retraction value?
2) Do you have any suggestions on additional changes to make in this case?
3) Could it be a problem caused by too wet filament?
Could it make sense to buy a filament dryer?
RE: Stringing issue with ColorFabb PLA Semi-matt white
I have had good results taming stringing with Bobstro's settings:
Retraction length is set to 0.2mm
Lift Z is set to 0mm
Retraction speed is set to 50mm/s
Deretraction speed is set to 25mm/s
Lift Z is a major cause of stringing but setting it to 0 can cause other issues depending on the model but it usually works for me.
I print mainly in white, although I use a different brand. I found 220 temp works best. White filaments have a lot of pigment and often print better at a slightly higher temperature.

Thanks for your reply.
With your settings i get the worst scenario. I guess that the hot-end temperature is too high, but also with retraction length set to 0.2 i have troubles just when start printing (as you can see in picture)

It could be wet filament, then.
