What Does 'Laser Parameters' Mean?

The PPI (pulses per inch) parameter determines how many laser pulses are being fired per inch of engraving. To achieve a good result, this really should be the same / a multiple of the dpi setting that is selected in your print setting. In Ruby® the PPI settings are adapted to the DPI settings automatically. If you set this parameter to 'Auto', JobControl will automatically determine the optimal resolution for your laser pulses. 

During the cutting process, the Frequency parameter is recognised and displayed to you in Hz (Hertz). This specifies the number of laser pulses per second. Usually, for a CO2 laser, the value can be set within a rough range of 1,000 to 60,000 Hz. For example, if you wanted to achieve a smooth, polished edge when cutting acrylic, you'll need to be using a higher temperature. That means the value needs to be set to at least 5,000 - 20,000 Hz. However, when cutting wood, a low frequency of something like 1000 Hz is necessary to achieve a bright, perfect cutting edge. 

Every material reacts differently to a laser process. During laser engraving and laser cutting, the supply of compressed air can significantly influence and improve the results. Furthermore, Air Assist protects the lens against damage as it prevents dust from adhering to it. The Air Assist is switched on and off automatically by the software. If the Trotec Laser is delivered from the factory with Air Assist and pump installed, the two units are directly integrated in the enclosure. Trotec laser systems are equipped with Air Assist; optional gas-kit available for connection to an external compressor.
