I recentst bought an anet a8 And had been getting decent results with pla filament from Tianze. Now i bought blue abs filament from esun and have been getting problems, this (pic) is only the verry first prints i did with it but i have Some troubles shown on the picture, there are like gaps And maybe even layershifting going on, what could this cause?

i use cura

240 nozzle

90 bed (cause it wont het any hotter than this for Some reason)

50 mm printing speed

1.2 wall thickness

the rest of the settings are basicly default
