I finally had a “need” to use the passthrough after three plus years of owning the machine!
Nothing too fancy, was making a template for a dashboard for a small motorboat, and wanted to test the fit of the components and the dashboard before making a final cutout on my cnc router.
The passthrough did it in three separate cuts. The only flaw was that I didn’t have the juice turned up quite enough to cut through the cardboard cleanly, but overall it was a success. Very small imperfections in the alignment, no more than 5 thousandths if that, barely discernible to my middle aged eyes.
And, the template gave me an opportunity to modify the design slightly for a better fit, so, mission accomplished.
