- Physics settings include joint-loss and brake calibration against a physical test print.
Field notes
The editor exposes track geometry and print construction as separate sets of controls, including support spacing, column width, and whether a centre spine sits under the ties. The print plan says it creates one STL per part, with parts sorted into track, supports, and baseplate folders and assembly notes included. Physics settings cover rolling resistance, loss at joints, and brake strength; the page advises measuring rolling resistance with a calibration rig.
