I am a beginner and this laser engraver is equipped with everything I need. I USED GBRL SOFTWARE WITH A MAC SYSTEM AND THE CONNECTION WAS EASY. When cutting wooden blocks, I find it as easy as carving planks. And the effect is not bad, it is a good laser machine.

The machine came a few days earlier than stated. Very well packaged and the installation also went smoothly. After I executed the commands and calibrated the device, everything went as it should and the machine correctly found the position of the laser head. I hope that it will remain stable in the future and that the values will remain as it is calibrated. Everything works correctly I am really impressed with the performance of the machine and the results of the laser work.

I did find that there was some smell while using it and found it would be better to use this engraver in a ventilated area. I think it should be necessary to buy another air assist to direct the airflow to the outside, the effect will be better!
