Heat beds are a component of a Print Bed. You probably realized that this is tricky stuff which is why there's a little device that takes care of this for us which is called a Stepper Motor Driver. This can happens especially with cheap motors then they are useless. Stepper motors don't ware out since there's no friction, however the soldering that attached the wires to the motor can soften and melt if the motor gets too hot. If you hear grinding don't worry, it's just the noise of magnets and coils playing tug-a-war. A stepper motor doesn't have mechanical pieces inside, it's all magnets. This is called bipolar stepper motor which is what we need to use. To stop the rotation, simple inverse the sequence of the coils switching on and off. Switchinf these coils on and off will cause the rotor (attached to the permanent magnet) to rotated. Since the permanent magnet is locked in place and can only rotate, it will rotate away from the positive magnetic force and towards the negative magnetic force. So one coil with a positive and negative wire is placed next to and perpendicular to a second coil with a seperate positive and negative.В To create the rotation movement, the first coil will generate a positive magnetic force near the positive pole of the permanent magnet core while at the same time (or shortly after) the second coil will generate a negative magnetic force near the permanent magnet.

Becareful to not create a short circuit on the top of the stepper motor driver when installing the heat sink.ДЄ stepper motor will have at least 2 positives and 2 negative wires and a permanent magnet. You can also add a small fan toВ help even more. Heat will move from hot place (the chip) to cold place (the heat sink). The heat sink will suck the heat away from the chip since it conducts heat. everything gets unsynchronized ! To help avoid this, you should add a 'heat sink' on the micro chip (the black square) to help it cool down. Guess what happens when you have 4 of these doing different tasks in a synchronized manner and one of them decides to shut down for a fraction of a second. When it gets too hot, it has a feature that switches the chip off for a fraction of a second or more to allow it to cool down, and then continues. Since these chips are small and they can let through several amps of power, the chip can get very hot. A stepper motor can be controlled by many types of stepper motor drivers, in this case we use A4988 chips but there are others that exist with different characteristics. Those pins are ultimately connected to electrical devices like motors, heaters, and fans that perform a task.ДЄ stepper motor driver is a specialized chip that receives electrical pulses from the Ramps 1.4 and then interprets these signals (commands) and then sends electrical pulses out some other pins towards the stepper motors.

Your PC then sends these G-Code commands to the Arduino computer which takes these software commands and interprets them and then turns switches ON and OFF sending electrical pulses and power to specific metal pins (inside the black sockets along the edges). So your PC does the computationally intensive calculations and processing, then translates the instructions to print to G-Code. It's also built to use certain computer languages including G-Code.

Since it's intended to control other devices such as motors, it's built with the capacity to use and direct more power to it's pins to control a wider range of motors sizes and type.

However an Arduino is a computer that is designed to control other devices and it assumed that the Arduino will be controlled by another computer like your laptop. A Raspberry Pi is designed to be a small extremely inexpensiveВ widows type personal computer with graphic capabilities etc. The Arduino Mega 2560 is similar to a Raspberry Pi computer but different in many ways. Its so affordable thatВ people will buy and includeВ an Arduino in each device they build as opposed to reusing (plug and un plug) the Arduino for other devices.

In fact it's so cheap that most people building electronics will build it around the Arduino even though it provides way more computing power than is really needed for simple devices. This is very popular a small low cost computer. This is the Arduino Mega 2560 (called outside the U.S.).
