The model of the Laser Engraving Machine located in Hackerspace.gr (Ampatiellou 11, 11144, Athens) is HQ-3020B. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as CorelDraw and Inkscape.

Maintenance

Laser cutter mirrors and lens should be cleaned every time before startup and thoroughly one per month as instructed in this guide.

Once per 6 months the cooling liquid needs to be grained and replaced by new. The liquid is a mix of distilled water and anti-algae solution. With every cooling liquid replacement is also good to perform a cleaning of the cooling system following this guide
