My retraction settings are 1.25mm at 30mm/s…and I’ve never stripped the PLA like your picture shows. That’s on a TAZ 6 w/ the v2.1 head.
The only thing I can think to suggest is to check your idler setting…I actually had mine cranked too tight for a while, and would get a nasty noise from time to time…maybe a partial stripping? It never failed a print though. I was basically compressing the PLA, making it wider, and it would start to bind. I printed out the idler setup block, adjusted to that, and have never had an issue since. Based on your picture, it looks like you are getting deeper tooth marks than I do but I can’t tell for sure.
Also, depending on your flavor of PLA, that temp may be a bit too low…so maybe the extruder is having to fight to shove material in to the hot end? Just a guess. I use Voltivo Excelfil PLA and it likes 205-213.
