Just installed machine, and everything looks nice.

But my first test cut shoving incorect cutting, insted 90 degree stright cut my machine cutting something like 115 degree angle. This is 3mm plywood. Looks like the laser head is not installed properly. I do not see options that can be adjusted. If you cut 10 mm plywood different it will be much biger. Check yours machines probably doing same things. I am thinking to return mine because of this, even my diode laser cutting more corecctly.
