problem with raft printing "pilling" in cura 2.3.1

[tyssoon 1]

hello,

i try to print with a raft and i obtain some "pilling" (not sure about the translation). I mean, on the second layer of the raft, the lines are cut, forming micro bullets of plastics, and of course the third layer isnt flat.

I print with PLA, 200°C, i have no problem of printing with brim or skirts. only with the middle layer of rafts.

I think it's a cura"s setting problem, can you please help me ?

I solved it myself ^^

it was a printing speed problem. i slowed it and it's now fine.
