FAQ
What shaft size do potentiometer knobs use?
Most potentiometers and encoders have a 6 mm D-shaft with the flat at 4.5 mm — the generator defaults.
The knob is loose or too tight on the shaft — what do I change?
Adjust the shaft diameter in 0.1 mm steps. Printed holes usually come out slightly small, so add 0.1–0.2 mm for a push fit.
