Never calibrated your printer?
OK, if you bought an almost-assembled kit, you likely also got a reasonably working configuration with it. Still, calibration allows you to raise precision with...
This nicely describes why stiffness matters. A sturdy box won't notice when you knock against it.
Maybe that's a bit hard to believe, because many common 3D printer designs do not exactly shine...
Those who want to enhance their print quality often face the problem that calibration can be quite tedious. Messing through 10'000-line configuration.h files and such stuff.

No frame? Uh, that'll wobble a lot. :-)
But yes, one can build a printer for almost nothing. My last one, a Mantis Electron, did cost just some $200 with all new parts. And it works perfectly.
It's simple: Freeware has to be taken as-is; Open Source allows you to fix bugs, change its behaviour, add features. You don't have to, but you can.
1. Steps/mm of stepper motors. Servo drives aren't infinitely accurate, either.
2. Stiffness of the printer frame. That's why all the good models come as box with (partially) closed sides.
3....
