The material is not sticking to the building platform!

[Magor]

I set everything ready to the printing, then the printing starts, but the material is not sticking to the surface. It just grows around the extruder. I cleaned the surface properly with alcohol, I set the gap between the extruder and the plate correctly.
Do I need a piece of glass on it? In the description it is said that "Super-flat aluminum alloy print surface for better adherence". So I guess there is no need to glass.

How about use some spray on the bed? and the temperature 65for PLA, try it. And you can buy a glass, it's more useful I think.

About what kind of spray are you speaking?
For sure: greasing, adhesive, cleaning, anti-mosquito, body deodorant?

The best will be to hear particular name of spray and of manufacturer.

I'm using this one, check the picture below:

Thank you a lot

Huh. Returned while commiting to buy. But it is not a spray? It is PVLA.

[Mark]

my bad, yeah it's PVAL, not PVLA.

[liutas4x4]

Sorry for beeng so perisher: PVAL and PVLA is common mistakes, written on cans. It does not matter - there are the same we are speaking about, - water based glue.
My question is about Spray: this glue is common in liquid form, but I never saw it in spray. It matter: while spray distributes on surface more eventually, the liquid form may lead to too thin layer problem, not it?

[Mark]

Don't worry about that, it will not affect the thickness of the layers, and it helps the filament to stick to the bed easily.

OK. I'll check it @ evening.
Thank you.
