eBay Chinese CO2 Laser Cutter & Engraver – Slanted Board Focus Measurement

As in this episode we will be using the slanted board method to determine the focus of our new Light Objects 18mm ZnSe lens. Because the board slanted (raised on one end by 2.54cm). The laser will start out of focus, run into focus and then back out. We can then measure with our scale the distance up from the bed to the position on the board where the bean is at it’s finest to find the sweet spot for the focal point of the laser.

eBay Chinese CO2 Laser Cutter & Engraver – New Light Objects 18mm ZnSe Lens

As in this episode we will be looking at the new Light Objects 18mm ZnSe lens which the post person brought.

Worth note we ran into some issues as think it is too good in that it has a tighter kerf than the original lens and when cutting acrylic especially multi-pass. The kref would fill back up with melted acrylic so I had to de-focus making for a wider kerf. I still need to sped some more time playing with it to dial it in finding it sweet spot.
