X1 encoding: the rising or the falling edge of channel A is counted. We can increase encoder’s resolution by counting the rising and falling edges of two channels, detail is explained below. When it moves/ rotates in a forward/ clockwise direction, channel A leads channel B, and in case it moves/ rotates in backward/ counterclockwise direction channel B leads channel A. But for quadrature encoder, it produce two channels, named channel A and channel B. With a single output encoder, it has no way of detecting in which direction the motion is happening. The two output channels from an encoder, with one being offset by 90 electrical degrees, or one quarter of a cycle that usually called quadrature encoder. The optical encoder is widely used due to its low cost and ability to provide signals that can be easily interpreted to provide motion related information such as speed or position. High LPI indicates greater detail and sharpness.

Lines per inch ( LPI) is a measurement of printing resolution.

In the case of rotary encoders, resolution is specified as the cycles per revolution ( CPR), some manufacturers use terms like “ counts per revolution” (also abbreviated CPR) or pulses per revolution ( PPR).

Optical sensor and control board: It is not clear, part number maybe J15 (0947). OPTICAL ENCODERS: There’re 2 kinds of optical encoders in DELL printer as follows: I only saw two DC motors equivalent to my printer motors, as follows:Ģ. But I could not find out the specifications of these motors on MABUCHI MOTOR website according to the order number written on the motors body. Through my searches on internet, perhaps these motors belong to the MABUCHI MOTOR manufacturer. DC MOTORS: There're 2 DC motors for X & Y axis as follows: 1pcs x Aluminum Flexible Shaft Coupling, Inner Hole Size: 10mm x 10mm.ĭetails of printer components are described below:ġ.2pcs x Male & Female 40pin 2.54mm Header.2pcs x 2.54mm Pitch 40 Long Pin Single Stackable Shield Female Header.1pcs x Single/ Double Sided Printed Prototyping Board.2pcs x XH2.54mm – 2P 20cm Wire Cable Double Connector.2pcs x XH2.54mm – 4P 20cm Wire Cable Double Connector.1pcs x Old CD/DVD Burner Writer Rom Player Drive.I used old printer head frame from DELL printer, one optical encoder is linear type and the other is rotary type.

To install the library, navigate to Sketch > Include Library > Manage Libraries… Wait for the Library Manager to download the libraries index and update the list of installed libraries. This library is not included with the Arduino IDE, so you’ll need to install it first.

It supports multiple steppers at once, with independent concurrent stepping on each stepper.

It supports acceleration and deceleration.

It outperforms the standard Arduino Stepper library in the following ways: So, for our next experiment, we will use an advanced stepper motor library – the AccelStepper library.

However, if you want to control multiple steppers, you’ll need a more powerful library. The Arduino Stepper Library is perfect for simple, single-motor applications.

For example, on a 100-step motor, if you set the speed to 1 RPM and call step(100), this function will take a full minute to finish. This means that the Arduino will wait until the motor stops running before proceeding to the next line in your sketch. Please keep in mind that step() is a blocking function.
