Abstract
In this paper, the feasibility of using iron-cored permanent magnet linear synchronous motors (PMLSM) to develop microsteppers with multiple DOFs is demonstrated. To do this, the accuracy of the mathematical model of the longitudinal and normal forces generated by one PMLSM as well as the performance of a nonlinear feedback linearization controller are investigated. Demonstration of several PMLSMs together can control three DOFs. In both experimental setups, linear guides are used to constrain the motion to be purely translational. Linear guides entail friction, which is undesirable in the photolithography process. Future research involves eliminating linear guides and controlling six DOFs (translations and rotations of the platform).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
