Printer suspension, any data?
Hi,
there are two mechanical extremes for the suspension (think "car") of a printer:
- Enforce zero movement: Place on a solid stone floor, maximum force / torque at the contacts but the movement vector is ideally zero
- Enforce zero force / torque: Place on Hula feet with thrust bearings or suspend between bungee cables (as an extreme thought experiment) or shoot into a low-earth orbit (hope your WLAN is good...) The boundary conditions don't allow force or torque, the printer can move freely.
Reality is of course somewhere in-between, and probably more complicated. E.g. the source of vibrations - the XY gantry - is actually quite far away in "Z" from the feet.
Is there already some consensus as to what works best? Of course, tuning needs to be re-run on the actual suspension, or results are meaningless.

I have both Hula feet and a very rigid tabletop. Subjectively it seems better. I have been planning to do a before/after comparison at some point.
