Hiệu chuẩn Input Shaping: Ringing Tower dạng cube (bản thay thế)

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}
