perfect

This is good laser machine. 100w is more than enough for cutting easily mdf 10mm in one pass at 75 % power 5mm /s. Good decision when order ad water chiller in package. I regret because we dont order bigger smoke extraction ventilation because if you work wth mdf and hdf as me, you will need more power ventilation system extractor. I ordered here in my country, and now i have less smoke in room. Machine is in good factory calibration need very litle adjustment to set first work. Recommend!
