I was able to perform my first dry run tonight. I'm not sure how much one is suppose to be able to detect movement by touching the frame while the machine is printing, but it seems to me like adding rigidity would be helpful.

For reference, I already have a 6mm aluminum i3 rework frame. Let's say I have a desk that I absolutely don't care about. Is there anything to be gained from fashioning a bracket and bolting the printer to the table? Perhaps at the bottom and also along the top such that a "horizontal beam" is parallel to the Y axis?

Does this even matter?

Thanks
