Ahem. You'll eventually wonder what causes small shifts in various layers of your objects... [grin]
The extruded thread making up the objects will be less than 0.5 mm wide and you can
see variations well under 0.05 mm. For comparison, human hairs are about 0.04 mm in diameter, so there's plenty of room between "seems to stay put" and "doesn't move at all". Those ugly binder clips serve a useful function, although there are other ways to keep the platform in position.
Getting good results from a 3D printer requires paying close attention to details that can't
possibly make any difference: small temperature variations, tiny angles, minute position changes, slight diameter changes, and a host of other "irrelevant" measurements. The M2 will deliver accurate and stable results over the long term, with just routine maintenance, but (as with any 3D printer) achieving great results doesn't happen by magic.
Don't feel bad: we all started from where you are now (some of us with
much worse printers) and the forums have a wealth of information. Take a look at the photos in the Showcase section to see what
you will be doing in short order.
Welcome aboard...
