pre-sliced Orca Slicer VFA test for Prusa XL
Description
PDFI am investigating an issue with perfectly repeating VFAs (Vertical Fine Artifacts) on my Prusa XL. By the time, I found more and more examples on other user's Makes that show the same pattern.
The problem is described here: https://ellis3dp.com/Print-Tuning-Guide/articles/troubleshooting/vfas.html
For comparison and reproduction of the problem I exported this pre-sliced gcode for Prusa XL in stock settings (you can change the toolhead). You can generate it for yourself with Orca Slicer 2.1.0 (I had problems with versions below and above that):
- Prusa XL, 0.4mm Nozzle
- Prusament PETG, 250°C first layer, 250 °C other layers
- VFA Test
- 20 - 160 mm/s
- 10 mm/s increase
I am not responsible for any damages running my pre-sliced gcode, which generally has to be done with caution. Please stay with your printer and prepare to interrupt the print, if you notice something strange, especially during the preparation phase of the print.
The .stl file ist just for demonstration, it is generated by Orca Slicer, you do not need to print this, as is contains no speed changes. Orca Slicer will generate the STL for you in the calibration menu.
Please share your makes, which are comparable if you use glossy (black) PETG (Prusament or other brand) and the pre-sliced gcode or the same settings.
Attribution: The VFA calibration test is generated by Orca Slicer, wich was forked of Bambu Studio, which was forked of Prusa Slicer, and so on. Thank you! See Github link below.
Discussion in the Prusa Forum here.
Here you can find some examples of VFAs that seem to be generated by the Prusa XL:
