Hack Chat 0x01: Introduction to Laser Cutter
Steag Center For Smart City Technology is organizing Hack Chat regarding Laser Cutter. The Center is equipped with 150W C02 Laser cutter and Engraver,
In the session, we will look into the working principles and operation workflow the laser machine for cutting and engraving.
The Session exclusively for the Rajagiri School of Engineering & Technology students.
Date: Feb 6th 2020
Time: 5:00 PM to 5:30 PM
Venue: Steag Center For Excellence in Smart City Technologies, KE Block Extension RSET
Note: The Session exclusively for the Rajagiri School of Engineering & Technology students.
What is Laser Cutter/Engraver?
Laser cutting is a technology that uses a laser to slice materials. While typically used for industrial manufacturing applications, it is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. (Wikipedia) .
CO2 (Carbon dioxide) Laser?
The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964, and is still one of the most useful. Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO2 laser produces a beam of infrared light with the principal wavelength bands centring on 9.4 and 10.6 micrometres (μm). (Wikipedia)

Really insightful on how to use the laser cutter, especially in projects based application
As a student spending money on website hosting is really a big problem, and Thanks to GitHub pages now we can host our website for free thanks @salmanfaris for this article, looking forward to see more useful article like this
@Ggreeshma-stani Nailed the PCB in terms of the schematic. But you got it a little bad on the layout side. There are some thumb rules while designing a layout of PCB.
Always place the oscillator and it's capacitors(C1, C2) near to the IC. If you have a doubt on this try checking the Arduino boards or any other boards. you will find an SMD chip crystal alongside of the Arduino XTAL pins. If you ask the reason for this that's simple, to avoid noise creeping in. Crystals provide the clock to the entire digital logic inside the IC. So, there should not be any noise in it. If noise is there, obviously you'll have timing issues.
The bypass caps on the voltage regulator must be placed close to the regulator's input and output pins. The reason for this is also pretty simple, bypass caps will filter out noise coming from the power supply and few other reasons too. So, try placing these bypass caps as close as possible to IC.
Apart from these points, the PCB looked good. Great work. Remember that this message is not to discourage you but just to give a suggestion so that you'll improve it in the next design.

@salmanfaris the pressure range that we have to measure is between 5-10 cmH20 (ie almost 0.07 - 0.0.14 psi)
