'New Matter' launching the MOD-t Affordable 3D Printer Soon via Crowdfunding Campaign

Hi,
What about the possible "clattering"?? (I don't know if this is the right word to describe it), I refer to the little up and down movements due to the gears itself. If the bed is not held into the gears, with some guides as most printers do, every time a tooth is pushing the bed, it can move upwards instead of moving in the same plane. All the more if the bed is unbalanced and one of its feet is touching the base.
I know the movement could be mostly imperceptible but when I'm trying to print something with 0.05-0.1 mm layer thickness, that little movement could be very important in terms of quality.

Theoretically, the involute profile of the gears will give perfectly level motion. But of course, the gears are not perfect, and there will always be a tiny amount of up & down movement. In the prints we've tested, there is no noticeable up & down wobble in the print surface. (I'll try to get some hi res photos to post soon.) Also note that the main benefit of a really fine layer thickness is to hide the layer lines, and the layer lines still disappear even if there is a tiny about of variation in the build platform height.
