Static-test checkpoint

This is a clean starting layout, not a final certification. Tape the guides, load the actual blank with the intended reel and line path, then move or add guides wherever the blank, guide height, or line clearance demands it.

Smooth progressive curve

Starts with your chosen first-guide distance and automatically solves a smooth increasing progression so the stripper guide lands on the exact target measurement.
