Double shell lines, bad circles and first layer not sticking

[halobump 0]

Hello guys,

I'm new to 3d printing and recently I bought an Anet A6. I read many guides and settings and printed 2-3 models after many attempts. I want to print this model https://www.dropbox.com/s/opb7mvzoxky47ey/Crown.stl?dl=0

My result of the first layers is this https://www.dropbox.com/s/y60wwepsifqnuwl/IMG20170711112438.jpg?dl=0

So the 3 problems I face in the title are double outline (even if I have the same shell thikness everywhere), I can't print circles (from the sides it makes them like square) and most times the first layer is not sticking even if I adjusted the bed many times.

Also I have my PLA at 230 and the bed at 70. Otherwise there is no way for my layer to stick as I have airconditioning in the room and maybe this colds it.

Thank you in advance. Ask me for any settings or tell me if there is a way to mass copy and paste them here.

You realise you're on a forum where 99.8% of users are Ultimaker owners, right?

Seeing something similar on an Ultimaker I would diagnose it as backlash and tell the user to tighten the short belts that run the X and Y movement. For your printer, not sure. But search for "backlash Anet A6" and see what that turns up.

Oh, i didn't know that, as the Cura 3D software that was with the printer is from ultimaker. I will search it as I don't even know what is this that you said. Thank you.
