[Cold layer?]

Hi. first i test the temperature, and do the same.

Then i i lubricate the Z guide columns with the spesific oil, the Z screw was good. The tests after this are good.

Thanks for all.

[Cold layer?]

Hello, my name is Quicu, i have a ultimaker 2 printer from 1 mouth ago.

I'm doing tests, thanks to this forum and I have solved things , but now I have a problem I do not know how to solve .

Some times, some prints, not allways, the prints have a problem like a cold layer.

I'm working with 0.4 nuzzel, 0.06 layer and 28mm/s speed and 210º PLA, with CURA.

The printing is very easy to break in the deformed layer.

I dont know, if i have a temerature problem, mechanical printer problem... the problem is not allways at the same layer.

Thanks.

Quicu
