I would like to add a base under my M90 to increase it's already very rigid and stable design and to add some more weight to anchor the machine (I can't say more weight would help but it don't think it would hurt).
I think I read somewhere that Z never needs to be adjusted unless the machine is moved from one surface to another. I assume some rigid material bolted to the machine base would eliminate the need for recalibrating Z even if it was moved because two layers of flat material sandwiching the aluminum square tube would ensure a very firm foundation.
Once I shifted the machine sideways during a print and the layers came out of alignment. I can't see that happening with a second base. Lifting a corner of the machine does seem to induce twisting in the structure; this would also disappear with a base under the machine.
I am thinking to use maybe 25mm Baltic Birch plywood or MDF. Which would be more flat? Stable? Least likely to warp? MDF is cheaper. I think it's also heavier than the plywood because of the amount of glue in it.
Any thoughts? Is this a good idea or unnecessary? Thanks!
