Input Shaping Calculator

Interactive input-shaping calculator: ZV, MZV, ZVD, ZVDD, EI and multi-hump EI shapers applied to a damped spring-mass system. Shows time response, sensitivity curve and impulse sequence, and generates the matching Klipper configuration – useful for understanding resonance compensation in 3D printing.

• Eleven shapers to switch between: ZV, MZV, ZVD, ZVDD, EI, two- and three-hump EI and four more (UM-ZV, UM-EI, PS, SNA-EI), each on a damped spring-mass system.
• Time response, sensitivity curve and impulse sequence together. You can see straight away what a more robust shaper costs you in added delay.
• What happens when the measured resonance frequency is off: the sensitivity curve shows which shaper forgives the error.
• The matching Klipper configuration falls out at the end, for anyone trying to get ringing off their 3D printer.
