Intro to LaserCutting
Laser cutting is a technology that uses a laser to cut or engrave materials, it is typically used for industrial manufacturing applications and works by directing the output of a high-power laser through optics. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. The focused laser beam is directed at the material, which then either melts, burns vaporize away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.

Laser Safety
it is important to ensure that the laser cut is checked before and after you. Do not turn on the laser before you turn on the main switch, do not open the top with the laser button still on. always make sure you put the end of the gas pipe outside a window or door. always check the water tank and make sure it has water inside it

Machine preparation
Make sure to check all connections, this includes the power socket for the laser cutter, the smoke exhaust fan which should be open and running, the water tank, and the pump.

Running the machine
Turn on the laser cutter. place the material flat on the platform. place a block between the nozzle and material. rise platform to min the gap.
Power & Speed Demo
We create a demo which can check the best parameter. it is a 7 piece cutting demo with powers; 90,80,70,60,50,40,30 and a speed of 70mm/s.
​
The squares are drawn in fusion360 and imported into LaserCAD as a DXF file.
The Result
Each square is given an individual color during information insertion. the power and speed is also inserted and then the computer is connected to the machine and the process may begin
The cutter successfully cut through with powers, 80, 70, 60 and 50. it did not successfully cut through powers 40 and 30.
