Hi all,
in case someone got problems with the first layer.
This is how my 1st layer looked like with Extrudr PETG filaments and 0.4 noozle at 0.20mm layer height:
Generic PETG Profile at 0.95 Flow Ratio and 230 degrees noozle temp:
And then: Generic PETG Profile at 1.0 Flow Ratio and 230 degrees noozle temp:
So the solution in my case was to increase the “Flow Ratio” from 0.95 (Generic PETG Profile) to 1.0 (Generic PTG Profile)
These are my overall settings for the Generic Profile for PETG. I adjusted the max temps according to the Vendor reccomendations of Extrudr:
I did not touch any other Generic PETG settings, just the temps and flow ratio to 1.0.
I hope this helps other people who got problems with the 1st layer prints.
No problems here. Some weeks ago, I printed some parts with Extrudr XPETG Matte on my enclosed P1P. All parts stick perfectly together and had no problems with 1st layer.
I’m using OrcaSlicer and did the “Pressure advance” and “Flow rate” calibration with the filament before printing parts.
Hi Finsterwald,
I have not used the extrudr brand petg also @ 10 max volumetric speed your @ 133 max speeds.
My petg brands and colors have been running between 0.96 to 0.98 on the flow ratio and my temps can be 250c to 280c you will know if your petg is to cold if the color is flat but I also run faster petg speeds than you.
You can also even try your first layer height @ 0.24 if needed but 0.2 is working for me with petg also.
Plus I set my petg first layer speeds lower @ 40 and 60 infill you can push them faster but I just want my first petg layer down real good and perfect.
If your parts are coming out perfect than you are all good to go 
yeah, I have now also decreased my first layer speed to 30 mms. It certainly has a better foundation now.
From your first picture, you have used “Flow calibration” (the lines at the front of your plate), I would recommend to not use it especially on textured plate.
EDIT: Either set an average PA value or do a PA calibration in Orca Slicer. (And uncheck “Flow Calibration” on print start)
As I do have a couple of spools here of XPETG from Extrudr, would you mind sharing your filament and cooling setting?
Do you use any extended settings for start and endcode?
@derpuma, I’ve printed with “my settings”. But on end of march, Extrudr released their own custom profiles on their website (settings “extrudr profile”). Maybe try a print with both settings.
Thx a lot for sharing. Your filament settings look almost exactly like the one I use on my other printers. Interesting would be also the settings for cooling, as I had some problems with rougher outer walls with XPETG, especially when I print faster on my other printers. XPETG from my experience is a little bit harder to print with, compared with regular PETG, especially from Extrudr.
I will check out the Extrudr profiles too! Thx for sharing this info. I have over 20 spools of Extrudr filament sitting here, so did not visit their website for quite a while.
My settings for XPETG uses for cooling the settings of the “Generic PETG” profile from Bambu Studio. Based on my calibration prints and the Informations from the Extrudr XPETG datasheet I have only changed the “filament” settings.
For me it’s very interessting, that the “Extrudr profile” lists Density = 1.27. But their datasheet says 1.41 g/cm3. 
I think this is a mistake and they took the value from the generic profile, as it looks like it is not changes. I go for the value, Exdrudr stated in the material data sheet, which is 1,41.
Yes, I think too. But this shows me, that I stay with my previous method and creating my own profiles by adapting the generic profiles using the vendor datasheets for filament and the results of the 3 calibration tests from OrcaSlicer (flow rate, pressure advanced and temp tower).
