I’ve tried a few cuts on a 3mm poplar plywood circle and my setup was:

• 250mm / second, 100% intensity

i’ve cutted seven circles and every cirly with a higher number of rounds.

First Circle: 1 round, 2nd Circle: 2 rounds and so on.

The first total cut-thrugh was at

• 5 rounds with 250mm/sec and 100% energy.

So this is my optimal setting for cutting out 3mm poplar plywood with the Mr. Beam II lasercutter.

Next i will try faster speeds to optimize cutting time .
