Silvertail A0 Laser Cutter/Cutting Parameters

If you experiment with different materials or speeds, please note down all successful settings here,

Cutting

Acrylic (Perspex)

Thickness (mm)	Speed (mm/sec)	Power (%)	Corner Power (%)
2	50	100	80
3	30	100	80
4	20	100	80
5	15	100	80
6	10	100	80
10	5	100	80

Ply (Birch)

Thickness (mm)	Speed (mm/sec)	Power (%)	Corner Power (%)
2	60	100	80
3	55	100	80
6	15	100	80
9	3	100	100

Ply (Poplar)

Thickness (mm)	Speed (mm/sec)	Power (%)	Corner Power (%)
3	60	100	80

MDF

Thickness (mm)	Speed (mm/sec)	Power (%)	Corner Power (%)
3	50	100	80
4	40	100	80
6	15	100	80

Foam board

Thickness (mm)	Speed (mm/sec)	Power (%)	Corner power (%)	Examples / Notes
5	50	25	23	6 passes* for a clean cut with minimal foam shrinkage
5	80	25	23	for a 50% score cut
5	80	20	18	for burning line markers/text into the paper coating

(*) this needs to be retested since we are not supposed to make multiple passes over the same path
