Printing PETG on textured powder coated sheet with same quality as Prusa obtains on the MK3S front panel face?

I am trying to print my PETG parts with as good of a texture as Prusa is able to obtain on my MK3S front panel, which virtually has zero texture defects:

Here is the best I can get so far (I increased all nozzle and bed temp from default values by 5 degC which was better than the defaults):

 

To me, it appears that the material is not flowing into the texture as well, so higher in temps may work but how high can I go?

What will I see when I get too high in temps besides more strings?

I do not want to have my nozzle seize up with overheated plastic.

Any ideas how to achieve their results?

Are the parameters which they use in their farm available to us?

Dale

Hi Dale, I don't know about exact factory  settings, 
If you download  a Gcode set from the Prusa Printable files section, there should be a set of settings, included

Hi Joan, that is great info, I will get those gcode files and have a look.

I see that PrusaSlicer can export gcode easily but what about importing gcode so that I can use the settings in the gcode files in PrusaSlicer, if not can gcode settings be converted to ini files?

Hi Dale, 

You can use 
Export config and import config, to move and save setup info...

Hi Joan, I am unable to find the gcode here: https://www.prusa3d.com/prusa-i3-printable-parts/

I only see options to get MK3S stl files which won't have the Prusa settings in them:

Is there another place to look for the files, Google didn't help with a "prusa printable gcode files" search...

But I do not see a way to import config info or Prusa settings from a gcode file, I only see export to a config file, am I missing something?

BTW:

I have figured out how to achieve a similar quality texture but I would still like to see the gcode files with their settings in them 😉

1. My temps were (E&B_250,95_1st_then_258,98)

2. Lowered 1st layer thickness from 0.2 to 0.15

3. Set LiveZ so that it looks like the nozzle height on 1st layer is a little too low.

Try File->Import config and select an existing gcode file. If the gcode was generated in PrusaSlicer (or its predecessor Slic3r), the settings will be imported.

Ah thanks and sorry, I missed the fact that a config.ini could be imported and created from a gcode file 🙂
