Frequently Asked Questions

Winding Machine

Is CAD data for this project available?

No, the CAD data for this project is not open source. For more context, read our blog post: Why Open Source Hardware Is Hard

Why not NEMA stepper motors?

NEMA steppers could be used. We use BLDC motors just because we build them.

Why closed loop control?

Closed-loop control is absolutely critical. If an open-loop stepper misses even one step (e.g., due to load, acceleration, or external force), the entire winding pattern gets messed up. Closed-loop ensures the motor always knows its exact position, correcting for any missed steps or external disturbances.
