Describe your issue:
After doing Input Shaping with KUSBA using the following commands:
SHAPER_CALIBRATE AXIS=X
SAVE_CONFIG
SHAPER_CALIBRATE AXIS=Y
SAVE_CONFIG
Klipper recommended shaper_type_x = ei, shaper_freq_x = 40.8 Hz, sm ~=0.19, accel<=3100; shaper_type_y = mzv and shaper_freq_y = 35.2 Hz, sm~=0.16, accel<=3700.
In OrcaSlicer, I used the following settings:
Basic information->Advanced->G-code flavor: Klipper (rather than Marlin)
Other layers speed
Outer wall: 15 mm/s (higher values produced poor surfaces with lots of holes on the vertical wall)
Inner wall, Sparse infill, Internal solid infill: 150 mm/s
Small perimeters: 50%
Small perimeters threshold: 0 mm
Top surface: 100 mm/s
Gap infill: 30mm/s
Support and Support interface: 80 mm/s for both.As for the Travel speed: Travel 120mm/s.

Normal printing: 500 mm/s2
Outer wall: 3100 mm/s2
Inner wall: 10000 mm/s2

Sparse infilll and Internal solid infill: 100% for both
First layer: 300 mm/s2
Top surface: 3100 mm/s2
Travel: 10000 mm/s2All Jerks (XY) parameters are set to 2 mm/s
Advanced Extrusion rate smoothing: 0 mm3/s2Flow ratio: 0.9981
Enable Pressure advance with value 0.05
Retraction Length: 0.3 mm
Retraction speed: 20 mm/s
The resulting print is not even. It looks like somebody printed it using a brush. There are also two small holes. Also, the vertical edge indicated by the green arrow is supposed to be straight and sharp but it ended up rounded along the height. Previously, I did a PA Calibration (PA Pattern) in OrcaSlicer but all angles were rounded. I tried various values but they all didn’t look sharp. Any good suggestions on how to improve the vertical wall so that it is smooth, sharp on the vertical edge and nice even looking?
