VHS has some new laser cutter lenses!
For information on how to change, use and care for these lenses check out the VHS Wiki → VHS Laser Lenses Documentation
There is a 2.5" standard lens(green tape), a 4" lens (orange tape) for cutting thick material, and a compound engraving lens (blue tape).
All VHS users are encouraged to experiment with these lenses and share their settings with the rest of the community. For an excellent example of sharing laser cutter lens settings please see → Laser Cutter - 7/16 Maple Hardwood
