Hi, with my tronxy x5sa pro i have some problem when I start first layer. Before print first layer the nozzle spits some PLA dirtying the first layer and consequently the whole print. To overcome this problem I added some lines in CURA that print on the edges of the bed pla by cleaning the nozzle.Do you know any fix for this annoying problem? Does it happen only on the tronxy? Is it a question of the extruder?
