Why 99% is NOT Enough - Marble Machine X Accuracy test In a recent episode from Wintergatan, Martin Molin dives deep into the workings of his intricately designed Marble Machine X, focusing on the importance of absolute precision in its operation. The video, titled "Why 99% is NOT Enough - Marble Machine X Accuracy test," brings a meticulous examination of how slight deviations can lead to significant issues in the machine's performance.

Overview of the Testing Process​

Molin begins by introducing enhancements to the Marble Machine X. Specifically, he tests the divide-by-four mechanism, which is crucial for distributing marbles into four equal channels. This distribution is essential to maintain smooth operation. However, he quickly realizes the challenge of achieving perfect balance over extended periods. During a short test run, it becomes apparent that channels one and two are receiving more marbles compared to three and four. While the lower dividers worked perfectly, the upper one struggled with consistency. Molin records how this imbalance could lead to a backup in the marble flow, resulting in critical failures.

A Critical Failure​

The situation escalates when the marbles begin to get stuck in the pipes, ultimately causing the machine to overflow on the floor. Molin humorously describes how the machine bombarded him with marbles, leading to a rapid shutdown in an attempt to manage the situation. The failure, he notes, stemmed not from the divider itself but from the angle of the pipe, leading to a catastrophic design oversight.

Seeking Solutions​

Undeterred, Molin reflects on his initial designs and quickly moves to create an upgraded version of the divide-by-four mechanism. This revamped design incorporates "rocking flip-flops," improving the accuracy and speed of marble distribution. In this segment, viewers not only witness the iterative design process but also learn about the trial-and-error nature of engineering.

The Final Outcome​

After implementing the new design, Molin conducts a stress test, which showcases the machine's newfound efficiency. The improved divide-by-four mechanism performs exceedingly well, even under intense conditions. Molin celebrates this success with a sense of relief, indicating the design phase involved significant risk and learning.

Conclusion and Community Involvement​

Molin wraps up the video by thanking his supporters on Patreon and encouraging viewers to keep an eye on future developments. The engaging experimental work shown in this video not only illustrates technical challenges in engineering but also emphasizes the importance of perseverance and community engagement in creative projects.​
