No Lack of Wobble

OK so I built my enclosure (see below) and it looked really cool.. Until it started printing. 

What is it with the Wobble? Has anyone solved the Wobbly Lack Issue?

I have reduced with twin towers that are mounted to one another.

A granite surface plate is probably the most cost effective. I opted for a granite pastry board.

Anything to get the mass up. My enclosure is also only two high. Three does not look stable...

I dramatically reduced wobble in my three high LACK towers by bracing the sides and backs with angle brackets. Only the bottom two of each tower were braced together, but even that requires quite a few brackets. The top LACKs remain removable.

I forgot one part, I added an 18x18 tile to each table.

I put a rolled up handtowel behind my Lack tower between it and the wall.  It helps.  I need to secure some foam blocks that rest against the wall.

I documented my process in this thread. Basically, you've got 2 challenges:

  • Increase the mass of the printer to reduce mechanical noise and vibration. You can do this by coupling the printer to a large mass.
  • Decrease transmission of vibration into large resonating surfaces. You can do this by de-coupling the printer mass from the surface it sits on.

Details in the linked thread. Be sure to check out the CNC Kitchen videos on the topics to understand the perils of simply using isolating feet.

Thanks for all the replies - currently my tower is a decorative storage rack for filament, tools and prints. It also still has the PSU attached to it. The Mk3 sits on a very sturdy, and heavy cabinet next to it.
