Delta Star Drive System

thingiverse

The Spectra fishing line is fed into the groove of the openbeam on the Delta Star 3D printer's drive system. This setup uses 623vv bearings as pulleys, with two at the top guiding each end into a groove and one at the bottom to loop it back up. A spool, paired with an additional 623vv bearing on the rail, provides a friction drive system for maintaining constant tension in a fixed length fishing line. This innovative line winding concept was inspired by: http://3dprinterhell.blogspot.com/ ### Example: The Delta Star 3D printer features an openbeam drive system utilizing Spectra fishing line. The fishing line is directly fed into the groove of the openbeam, with 623vv bearings acting as pulleys at the top guiding each end into a groove and a single bearing at the bottom for looping back up. A spool paired with an additional 623vv bearing on the rail creates a friction drive system that maintains constant tension in the fishing line of fixed length.
