Problem with first Layer

Recommended Posts

Posted (edited) · Problem with first Layer


i have the Ultimake 2+ since last weekend and always the first layer looks bad.

I tried to calibrate the bed new, increase the tempeture from 60 to 70 degrees,

lower the first layer printspeed to 20mm/s.

Edit: it is PLA the silver from Ultimaker

    You need to clean the class and try not to touch it as the oil from your fingerprints can cause this.

    Some isopropyl alcohol or glass cleaner is best.

    those bubble looking marks are where the filament it not sticking to the glass.
