Ready to see the simulation in motion? Watch the embedded video above. If you have successfully rendered your own version of the TMC FAE DCAY Hourglass Expansion, post your render time in the comments below. For the raw node setup and FAE solver files, check the link in the description.
| Segment | Time | Content | |---------|------|---------| | Hook | 0:00-0:20 | "If your stepper motor is screaming or losing steps, your DCAY setting is wrong. Here is why the Hourglass Expansion matters to every FAE." | | Problem | 0:20-1:30 | Show a motor making noise. Explain – Slow vs Fast decay. Show the ugly "valley" of distortion. | | Concept | 1:30-3:00 | Introduce Hourglass Expansion – A graph showing torque ripple expanding and contracting like an hourglass as microstepping increases. | | Solution | 3:00-4:30 | How TMC drivers (SilentStepSticks) use mixed decay to flatten the hourglass. Oscilloscope footage. | | Outro | 4:30-5:00 | "Next time you tune an FAE's nightmare system, remember the hourglass." | video title tmc fae dcay hourglass expansion
Oscilloscope waveforms, 3D hourglass morphing into a torque curve, TMC datasheet screenshots. Ready to see the simulation in motion
