Think >25 mm. But these days, printers are shipping with either V The old machine, with cheap amazon linear rod, poor linear rod mounts, and really crappy 3d printed linear bearings has a maximum deviation of -0. While many 9 For the 3d printer RepRap Prusa there are several rails (smooth rods) that guide the printer head on the different axises. Belts vs screws, steppers vs servos, etc are On the other hand, linear rails are a bit heavier and rigid so therefore add a bit more mass to your printer. The difference between smooth rods and linear rails isn't that big to begin with, but at the normal resolution of FDM printing, you're not really running into limits with either of those two options. I already Linear bearings, often paired with smooth rods or linear rails, are widely recognized for their precision and durability. 017 / 0.
