Now I want tell to you, how to send/receive the messages from/to Arduino in Linux-Terminal.

As you know, all devices of serial ports are represented by device files in the /dev directory. It is through these files that Linux OS communicates with an external device...

OLED I2C display have a 4 pins: GRD, VCC, SCL, SDA. These pins connect to Arduino in the following way:

M05  - stop spindle rotation

M03  - start rotating the spindle clockwise (M3 S2000)

M04 - Start rotation of the spindle counterclockwise (M4 S2000)

 

I want to note, that in engraving machines M3 - laser activation, M5 - turn off the laser and S -...

Function H performs length compensation, and function D performs radius compensation

Length compensation is possible in two ways: relative to the front plane of the spindle (pic. 1) or in relation to the "zero instrument" (Pic. 2).

The G02 command is used to move the cutting tool of the machine using circular interpolation, so that the movement to the end point specified in the block is carried out in an arc (circle) in the clockwise direction.

The use of this command is used directly to process the material with a machine tool.

The movement speed of th...

G17, G18 and G19 used for plane selection. Each is modal and applies to all subsequent circular motions.

The default plane selection is G17, which means that a circular motion in the XY-plane can be programmed without selecting G17, if G18 XZ-plane as active, ...
