Which side is master and slave on the CNC machine
If you’re new to CNC machines and machining, you may have a lot of questions about the various components of your machine. One question that I hear all the time is, “Which side is master and which side is a slave on my CNC machine?” Just like every other part of a CNC machine, both sides have specific functions. This guide will explain exactly what each side does and when they’re used.
The master and slave are on the cnc machine.
The master is the drive that sends pulses to the slave. In this case, the X-axis is the master, and the Y-axis is the slave. There is no hard or fast rule for which axis should be master or slave. It all depends on your design and how you are going to cut your material.
For example, if you have a long wide surface to cut, you may decide to have the direction of travel be along the X-axis and cut passes along the Y-axis. With this setup, you would want the X-axis to be master and the Y-axis to be a slave. However, if you have a tall workpiece with multiple passes in both directions X & Y, then it really doesn’t matter which one is master or slave as long as they are synchronized with one another.
The cnc machine is a computer numerical control machine.
The CNC machine is a computer numerical control machine. This is an automatic machine that makes use of a computer program to perform the cutting and drilling operations. The CNC machines are capable of producing accurate results as they are pre-programmed and are also capable of performing repetitive tasks at higher speeds.
In the CNC machine, one side is a master and the other side is a slave. The master device is used to give the command to a slave device and it depends on the type of CNC operation being performed. CNC lathe machines have one master axis, which is used to give commands to a slave axis. For example, if you want to cut something in a circular motion, then the master will be used for the rotating function and slave will be used for the cutting function.
Similarly, in a CNC milling machine, two devices are used as masters and the rest are slaves. The left side of the workpiece is used as a master axis and it controls the movement of the X-axis while working with this axis you don’t need to look at the workpiece because its movement will not affect your workpiece. It’s just like you’re using a ruler on your paper when drawing any shape.
Master side is where your main controller is located.
The left side is master, the right side is a slave. The Master side is where your main controller is located. The Slave side has no main controller and has a remote box that re-transmits signals from the master side to the motors on the slave side.
In other words: if you were to draw a line down the middle of your CNC machine, everything on the left is master, everything on the right is a slave.
The power supply will be the only thing that can be traced to both sides.
Example: I have an X-axis motor on the right side (slave). The motor will not be controlled by an encoder or drive located on that side – it will be controlled by a drive located on the left (master). An encoder mounted next to that motor will send signals back to that drive over a remote box.
Slave side is where your secondary controller is located.
This is usually the machine that you are running a program on (i.e. the one that will do the cutting). The master side of your configuration is the PC that has your CAM software running on it, which writes the code to your secondary controller.
The serial cable needs to connect both controllers together, such that they can communicate with each other. If you have a machine with two controllers in it, there will be two serial ports on each controller and you would use a straight-through cable to connect them together.
Main controller is the one which controls the other devices connected to it.
The master sends commands to the slave and the slave obeys. A master-slave relationship is usually a one-to-many relationship. For example, a keyboard and a mouse are master devices when connected to a computer.
The master also controls the clock signal (CLK). All devices on a bus must be synchronized with this signal. The synchronization is achieved by connecting the CLK pin of all slaves to the CLK pin of the master device.
Secondary controller is the one which allows you to control another device without having to access primary device directly.
When using a CNC machine, the secondary controller is the one that controls and monitors it.
The main difference between primary and secondary controllers is that primary controllers are used for certain activities only.
Secondary controllers have full control over all operations as well as external devices connected to them such as motors or other hardware components.
If you want to control a CNC machine with your PC, it’s possible but you need both types of controllers connected together; however, there are some restrictions on what type of communication can take place between them (e.g., serial versus parallel).
Most common use of secondary controllers is controlling printers, which can be done using USB, RS232 or parallel port interface if available on your motherboard but some motherboards only provide RS232 interface so they cannot print anything without secondary controllers being installed firstly before connecting it to primary PC via ethernet cable (which doesn’t require any additional drivers).
Usually, the primary controller has no problems communicating with any other hardware through its own interface because it only needs one interface cable from the primary PC to connect two devices together; however, sometimes additional cables will be needed when connecting some external input/outputs like limit switches, spindle motor encoders, etc if necessary according to their specifications – such as RS232 serial port connections for example (which requires special drivers).
CNC machine has a main controller and a secondary controller, which can be used for printing or other purposes.
The main controller is the master side, the secondary controller is the slave side.
The main control system of the CNC machine tool has two parts: (1) the main control system; (2) the auxiliary function subsystem. The main control system mainly controls the processing location of the workpiece, and the auxiliary function subsystem provides additional functions required by the machining process. The latter includes an automatic tool changing device, automatic workpiece clamping mechanism, automatic inspection device, and so on.
The main control system mainly includes a program input device, arithmetic unit, numerical control drive device, and machine tool interface.
