Cut up my battered and dented cork noticeboard into several new ones into trendy hexagon shapes. Took a few passes and adjustments to the settings to get all the way through. Worked out that there was no burn if I did them upside-down. It was interesting that the burn wasn’t on all the sides too.
All passes at 250sp and full power
Focus height
1st pass 0.46
2nd pass 0.40
3rd pass 0.35
4th pass 0.30
once I turned it over the 4th pass wasn’t needed.
