I’ve found lot of information about other shapers but for some reason I can’t figure out what MZV is short of. Is it Unity Magnitude Zero Vibration (UMZV), Modified Input Shaping Zero Vibration (MISZV) or completely something else?

MZV was created by Dmitry (dmbutyugin) for 3d printers. He discussed this briefly on Discord last year. When he was asked “Oh, and by the way, is MZV your shaper? I have not found that particular set of times and factors in the literature”, Dmitry responded: Yes, but there’s no magic in it. The …

Lets call it magnitude zero vibration.

Good question, actually. When researching about this topic, I came across: ZV: Zero Vibration ZVD: Zero Vibration and Derivative EI: Extra-Insensitive (sometimes also called Extra Intensive) MIS: Modified Input Shaping SNA: Specified Negative Amplitude UMZV: Unity Magnitude Zero Vibration But ne…

See my post above. This suits well to your UMZV.

Actually without any reference I do not want to speculate. There are papers that talk about a MODIFIED ZERO TIME DELAY INPUT SHAPING or a modified zero vibration (ZV) input shaping technique or a MISZV (modified input shaping zero vibration) I’ll stick to “Magical” unless someone know better …

Thank you for your answers and discussion. @LifeOfBrian I really would like to know where did you got the name magnitude zero vibration? I’ve seen ALL3DP calling it that but nothing else. I also don’t find any research papers on magnitude zero vibration only about UMZV. @Sineos I guess I should ju…

Maybe it is Multiple Zeta Values as used in the Riemann Zeta Function? Maybe this analysis tool is used in input shaping? See: Multiple zeta function In mathematics, the multiple zeta functions are generalizations of the Riemann zeta function, defined by and converge when Re(s1) + ... + …

Yeah I have it from All3DP but think there once was a table with those popular shapers and there whole names. However I don’t find it any more.

Perhaps we need a Knowledge Base Glossary page listing all the names of Input Shapers? It seems that the experts in the field know their terms so well that none ever explain what they mean - assuming that others in the field already know. Not much good for people who just want to select an option fo…

[image] JassMan23: Not much good for people who just want to select an option for their printer. Actually, apart from the “scientific interest”, I do not see any practical use: Klipper is not supporting most of the shapers you listed In the end they could be named MickyMouse1 to MickyMouse2…

OK I could delete it. It just thought others may be curious as to the meanings of option in their configs.
