although it says “Never change a running system” or something similar I changed the print head of this little fellow and swapped the RasPi 3 with an OrangePi Zero that was used on my CoreXY before.
Before all this I think I found a good config in terms of input shaping.
Due to changed mass of the print head I rerun resonance measurement with the ADXL345 for both X and Y and put the recommended shaper settings into the printer.cfg.
Then I printed a smaller resonance tower to save filament (Accel Ringing Test Remixed by _Frezap - Thingiverse) and noticed ringing.
Even without input shaping or different shapers and respective frequencies in my opinion the quality did not change…
Although without input shaping it looks the same I rerun the measurements with the RasPi3 but it was quite identical.
If you check the pictures there are two heavy resonance peaks on the X axis and I do not know whether the shaping can mask those properly.
I mean the print quality is not that bad but as it does not seem to change I’m asking for any ideas.
As it is quite hard to photograph I did not yet attach any photos of the actual prints. Just want to clarify whether there might be a bug or something or it is already the best due to those resonance twins or I missed something due to dirty glasses…
