Connector Basics particularly the USB section.If you need a refresher, feel free to pop on over to these links. You should be familiar with these topics before diving into this tutorial.

In this tutorial we will discuss what a terminal is, which terminal programs are best suited for certain situations and operating systems, and how to configure and use each program. There are lots of different terminal programs out there, and they all have their pros and cons. Once you have learned the ins and outs of a terminal application, it can be a very powerful tool in your electronics and programming arsenal. They allow you to see data sent to and from your microcontroller, and that data can be used for a number of reasons including troubleshooting/debugging, communication testing, calibrating sensors, configuring modules, and data monitoring. In short, serial terminal programs make working with microcontrollers that much simpler. This tutorial is here to help you understand what these terms mean and how they form the larger picture that is serial communication over a terminal. For someone who isn't familiar with these terms and the context in which they are used, they can be confusing at times. These are all words that get thrown around a lot when working with electronics, especially microcontrollers. As long as you have the adequate amps to cut through the metal and move at an optimal speed, experimenting with the air pressure is the best way to get the most accurate cut.COM ports. It's the air pressure (not amperage) that makes the difference for a clean and good cut. At 30 amps the cut will look about the same width as the 25 amp, but it’ll cut much more quickly and easily!.At 25 amps the cut will go a little quicker, and the 25 amp cut will have a few smaller kerfs.At 20 amps the cut will take a long time - it may just barely cut through the metal.Then cut it at 25 amps and 30 amps and check the quality of the cut.Turn the amperage down to 20 amps at 60 PSI, give that a try.Push down the knob to make sure the pressure regulator is locked in place.First, turn up the air pressure to about 60 or 65 PSI for 1/8-inch thick hot rolled steel.At first, it's set pretty low, right around 15 PSI. On the plasma cutter's front panel, you’ll see a pressure gauge.
