Hi guys,

So after a turbulent trip down ordering a chinese laser (had to scrap the first one, since it was defective to any extend) i finally have a decent machine running. However. (there is always a however).

Its supposed to be an 80w laser tube and its an EFR tube.

But as you can see on these 2 pics below, its struggling to cut 3mm plywood and 3mm acrylic, until it gets to a very very low speed.

Am I doing something wrong? Im using the focus pieces that came with the machine, which is roughly 8mm.

Im afraid, that I wont be able to cut anything thicker than 3mm without having to go down to maybe 5mm/s and with full power

Any tips and tricks?
