I’m considering adding a sliding mass dampers to my x or y axis to try and increase my high speed print ability. The x axis mass would be pretty constant throughout the print, y would grow as the print goes, but I’m thinking compensating for the bed mass would at least theoretically help.
My initial thought Is a 3rd slide of some sort, with a dense tungsten weight tied to the opposite direction leg of the belt. It would double the mass on the stepper and the belt, but larger belts and pulleys and larger steppers are feasible. Maybe a spring in line with the weight to prevent startup shock? The other thought is a rotary damper on the back end of the stepper.
Any thoughts? Is this a viable approach or just adding mass to a system that won’t benefit it?
