If your part is longer than your travel or you want to reposition stock, plan registered passes: cut a section, then move the foam to a repeatable reference (a fence or pins) and continue, so the segments line up. The key is that the foam returns to a known position each time — any shift shows as a step in the surface.
For very long extrusions, keep the wire span and tension consistent between passes. In https://cncfoam.com you can model the material block and position the cut, which helps you plan where each pass starts. Mark your reference clearly and cut a test to confirm the join is invisible before committing an expensive block.
