Settings for agate coasters

[vecchioni54]

I have some agate coasters from JPPlus. Their settings are for a 60 watt laser. I have the GF plus. Has anyone worked with agate and have a starting point they could share? Thank you.

Agate slice and mat board tests

[Agate%20sample] [mat%20board%20cutout%20sample] First full day with the Glowforge testing agate slice for engraving and mat board cutout. The tests turned out fairly well. Agate slice engraving settings (200 speed, 30 power, 1 pass) Mat board cutout settings - with painter’s tape applied (400 speed, 55 power and 2 passes) *Note - I did get some burn marks on the back side of the mat board. If this is an issue, placing tape on the back would probably work well.
