Snapmaker J1s input shaping tune wizard have a bug - not saving picked values. (FW 2.7.1) https://www.facebook.com/groups/snapmakerj1/permalink/1112429939797317/
To tune input shaping this model created. Why? There is a standard Ringing Tower model model to tune input shaping. Check it first.

But I wanted to do similar but different model by yourself. In Fusion360. I think it have some advantages.
- smaller - faster
- cube form - front and back sides
- each rows separated by line
But maybe it has disadvantages too. I do not have enough expertise.
How I calibrated my IS values and additional info can be found here: https://www.facebook.com/groups/snapmakerj1/permalink/1112429939797317/
How I sliced:
- layer h 0.2 w 0.5
- spiral vase mode
- no top and bottom shell layers
- brim
- max possible acceleration for model (10000m/s/s)
- reasonably fast printing speed (250mm/s)
- disable filament setting “Slow printing down for better layer cooling”
- Increase “Max volumetric speed” for filament to ~19mm3/s
- disable “Slow down for overhangs”
- maybe something more, check your flow and speed preview after slicing
To gradually increase input shaping values by 5Hz step to achive next distribution:
Row 9 - 65Hz
…
Row 2 - 30Hz
Row 1 - 25Hz
Row 0 - IS is OFF
Layer change gcode:
; layer_num: [layer_num] ; 0 layer print brim - it can be printed with current IS and LA {if layer_num==1} ; disable LA and IS M900 K0 M593 P0 {endif} {if layer_num==30} ;enable IS and then set current value M593 P1 {endif} {if layer_num>=30} M593 F{(25 + 5 * round((layer_num - 30) / 30))} {endif} G92 E0
