A serpentine belt, also known as a multi-rib or poly-v belt, is a drive belt that runs multiple components in a vehicle's engine. ... The serpentine belt employs an automatic tensioner that adjusts ...

Layer shift caused by the belt being way too loose. 3D printer belt tension seems like a simple thing to deal with — you set the tension and then check it’s good now and then.

Despite doing so much, most of us forget the serpentine belt even exists — let alone that its tension matters. But it does. A lot. Too tight and it'll grind bearings to dust. Too loose and you ...

Belts on a 3D printer should be tight enough, but not too tight. That can be an iffy thing to get right for someone who lacks familiarity with CNC platforms. Prusa Research aims to make it a bit ea… ...

Spring-loaded automatic tensioners are the most common today, introduced in the mid-1980s. They use a coil spring to apply constant tension and usually self-correct for minor belt stretch over time.
