[Problems in printing with PLA]

Hi,

Thanks for these tips.

I guess I have to check the nozzle.

I'll let you know what was the reason for incorrect printing with PLA.

[Problems in printing with PLA]

Hello to all.

Here is a new member of this magnificent forum.

I have bought my Ultimaker just one month ago and looking forward to learn exploit this miracle machine.

" If you want some honey be prepared to wasp's sting" as they said.

Some problems needs to be solved.

I have tried to print couple of parts loaded from Thingiverse with my Ultimaker.

With ABS printer worked very well but when I changed filament to PLA, troubles began.

First printer make the "grid net" below the object just fine but some 10-15 layers after, appears the first loose strings.

This means that object printing must be canceled to avoid waste of filament.

I have Cura 12.08 on my computer and it works well with the Ultimaker.

Here is the profile of printing parameters that with I tried to print PLA:

[profile]

machine_center_x = 100

machine_center_y = 100

flip_x = False

flip_y = False

What can I do to get my Ultimaker to print PLA properly?

Can someone please help me?
