@freemo Thanks for explaining how it works (I haven't paid any attention to that yet), and making a good argument for the choices made. :D
I recently did a massive redesign of a 3d printed magnetic stirrer I designed a few years back. Here's a brief writeup showing what changed (and why) and the evolution of the design process. https://www.cartesiancreations.com.au/design-revising-the-magnetic-stirrer/

Lovely work. Here's a couple of trials on my CoreXY (Custom 350x350x430). Rotated 45º. I think it's clear which print has had input shaping turned on. :D
