So what do you guys put your 3d printer on so that it is rock solid. I put it on my work desk (which is where my two 24" LCD are mounted onto a LCD mount). I notice that when the 3d printer moves, the vibration of the printer vibrates the table back and forth. This micro-vibration seems to be the cause of surface artifacts on my print. This is more prevalent on objects that are thin walls: a hollow box.
Is there a recommended surface to mount the printer on? Is this issue specific to my Printrbot Simple Metal (and I can fix it by 3d print something)? Am I coming up with this for absolutely no reason since the issue with my print quality is some where else?
I’ve heard of other folks complaining/commenting about the same thing and some have tried flexible, vibration absorbing feet and reported good results.
You could always try an experiment or two. Find a quick test print that shows these artifacts and print it on your current workstation, then on the floor, then on some flexy-feet.
I talked to guy who suspends his Printrbot on bungee cords! He said it wiggles around but was immediately got better prints. Sounds crazy but now I want to do a dude by side. And I wonder what zero gravity does… Gotta try that. I bet a floating printer in zero G would physically move half the distance of x y z as it moves. Ya, gotta try that.

A printer in zero G would move in roughly in proportion to its ‘moving’ mass divided by the remaining machine mass. It gets pretty complicated when motion is not in line with the body’s overall center of mass, so the machine is likely to rotate, too.
@Brook_Drumm I’ll do that with @Cohesion3D . The new frame design is incredibly rigid and we’re always testing it by lifting the entire machine by the handle and even the extruder cart on the single c rail which should be the weakest link.
I’ll either hang it by the handle/ 2 points on that beam or upside down. Since the bed doesn’t move, hanging it right side up and running a print would move the whole frame which might be a bit tricky…
