Calibrate Real Filament PETG Settings
Hi fellow Prusa users 🙂
I recently made the upgrade to the MKS version of the printer. As my NGEN did run out i ordered some PETG from "Real Filament" company.
Its quite cheap and easy to get by in Europe: https://reprapworld.com/products/filament/real_filament/petg/real_petg_smoky_black_spool_of_1kg_1_75mm/
Unfortunately the Prusa Settings for PET did not do the trick for me and i had to search the net quite a bit to find settings that produce good prints.
Here i want to share my settings as i think they are quite good for PETG but also want to get some hints to dial it in a bit better and make it perfect 😀
You can Download my Settings for the Prusa Scli3r here: https://drive.google.com/open?id=0B6IyuWA33ROBTE9zT1Z2VGNRS2c
Here is my best print so far with the settings from above.
What could i try for a better top finish?
There is some filemant in one of the holes. Ideas why just one? Thanks
What could cause these "lines" ?
Uneven lines.
If you have any suggestions how to make it look even better i would greatly appreciate them! 😀
PS: Yes that is PEI on the botton. This PETG sticks like hell. Make sure to cool the bed before removing.
Thanks for your help and have fun with the settings 🙂
Re: Calibrate Real Filament PETG Settings
If you clean the PEI with Windex window cleaner, it leaves behind a residue that will prevent the PETG from sticking so well, but still stick plenty.
You should NOT do PET on PEI clean due to this adhesion. I like windex, but some use glue stick.
Since I don't have, nor do I want, a google account, I can't see your settings. It would be better if you added them as an attachment (ZIPed if needed).
I think you should slow the printing down some to improve your print quality.

I think you have under extrusion. Possibly because you seem to print at 235 degrees, which is too cold. Try 245 for better results.

Hi
i calibrated my extruder and tinkerd with some settings and it helped even more 🙂
Is there an alternative for Windex cleaner in Europe ? US import is like 60 € per Bottle....
I will post pics soonish 🙂
Re: Calibrate Real Filament PETG Settings
I would think there is a European equivalent. It is just a window cleaner.

Im using a brand named Ajax (Sweden). This is manufactured by Colgate so i bet it will be available almost everywhere but maybe under different name.
I think any of the blueish window cleaner will work.

Re: Calibrate Real Filament PETG Settings
if you are from the netherlands, you could try glassex instead of windex. Or the knock-off from action, which works just as well.
I am using the orange petg from real and have found that it prints best at 245 nozzle and 70 degrees bed. all other settings i have left as is from the prusa pet tab and just saved the adjustments to a new filament profile.
My prints are just as good as with pla so i'm happy with these settings.
Before every print i clean the bed with glassex and prints come off without any drama.
Adjust your z-height so it just sticks well enough to the bed that you have to push it with a fingernail to make it come loose but not so much that you have to scratch it and you'll be fine.
good luck printing real petg ☺

Hi Patrick,
Thanks for the replay. I found out that the blue ajax cleaer also works good 🙂
As for the settings, i have to really print slow 10ms so the outer layers look really good. Did you achieve better results with higher speeds ? (I uploaded a picture to my google files, they are updated now too :-))
I printed a temp tower and i seem to geht the best results with 335 degrees of the nozzle 245 is melting some fine structures. But even with 335 degrees i get fine hairs, stringing but it got better.
Any other ideas ?
