with recommended or custom settings i have this results....as you see in first photo this is not a heated bed issue any ideas ????
From the first photo it looks like you are over extruding filament, try reducing the extrusion rate in cura for better layer quality.
Also for the first layer, I'd recommend printing in the centre of the bed, and also using the raft setting in cura.
Nozzle too close to bed or bed level issues
