However that's how i broke my first glass bed. :-(

The nozzle presses down on the bed when it glides over parts that have already been printed and those parts aren't entirely flat. If there's no give, the nozzle has a good chance of crashing into the printed plastic and skipping steps.

But it will also mean that if you have a whoopsie with your bed height being mis-set, you risk then doing serious damage to your x-carriage or nozzle tho..

So you can adjust the build platform. The bed isn't threaded, it relies on the spring pressure to push it against the top of the bolts.

Ok so this is the only reason? Because maybe I want to try using self locking nuts then with some washers in between. It seems to me the stability will be improved this way.

Just make sure you start your z-height and levelling with all 3 screwed down, then they shouldn't need to screw in more than a few turns to get it even.. if you start your adjustment with them already at half way, then by the time you're done they will be much much higher...

I have a solidoodle 3 and changed the wooden platform for the new aluminium. When I took the printer apart I noticed the springs make it possible for the heated platform to move around much more than I expected. Doesn't this cause the printer to lose accuracy?

My question: Can someone explain the reason of the springs below the heated platform?
