How to Use the Function of Rotary Marking?

Enable Rotary Marking

To control the Rotary Axis, users need activate the Rotary function by clicking the Layer object in Object Browser and then go to the Rotary Page of Property Table and enable this function. Or users can decide to enable rotary marking for each object or not under「Mark-Related Property Table」→「Rotary」. Layer rotary marking and object rotary marking are mutually exclusive.

Layer-Related Rotary

There are two methods of rotary: Cylinder Mode and Disc Mode. The difference between cylinder and disc is the figure of the rotary axis.

Cylinder Mode

Diameter: The diameter of the object.

Max Width: The ideal section width when marking. This value is based on the radius of axle.

Scale: Adjust the ratio of radius to reach the optimum marking effect. The default value is 1. Please refer to the following example and figures.

Example: Suppose that users set the value of rotate rate as 1.5, and the marking result is shown as Fig.6.1.03, all sections are overlapped. In this case, users should lower that value, such as 1.0, to make the marking effect optimum, see Fig.6.1.04. On the contrary, if the value of rotate rate is 0.5, and the marking result displays like Fig.6.1.05, there are intervals between each section. As a result, users should increase this value to make the marking effect become ideal, like Figure 6.1.04.

Cylinder Compensate: The default value of this function is disable. Enable the function, MarkingMate system will fix the overlapping of marking result according to the object’s radius and the Focal Length.

Focal Length: Input the focal length of the lens.

Disc Mode

Step Angle: Set the rotary angle for each step of marking.

Mark-Related Rotary

This page allows users to enable rotary marking for individual object. Fig.6.1.06 is the property page when selecting a general object.

General Object

Enable: Allow users to enable or disable the rotary axis function.

Start Position: The start angle of the rotary axis.

Text Object

When a general text object has being selected, the Rotary Page has some particular options, like Fig.6.1.07.

Text option

Separate To Character: Separate the selected text into individual characters.

Pitch: The distance between each character.

Center: Calculate the pitch based on the center of the character, see Fig.

Edge: Calculate the pitch based on the edge of the character, see Fig.6.1.09.

Diameter: The software needs the diameter of the workpiece to calculate the pitch when select Edge mode.

Rotary Control Panel

After enableing rotary, click button and do the further setting.

1.Click “MOVE TO…” button and input the degree value in the dialog box and click “GO,” the rotary axis will rotate to that specific angle. The rotating speed can be adjusted from “Speed” parameter.

2. Click the two direction buttons to move the rotary axis.
3. Click “ZERO” and the program will set the present position as (0,0).
4. Click “HOMING” and the rotary will move to program origin.
5. Click “MOVE TO P”, the rotary axis will directly move to the setting position (P0~P9). Users can click “SETUP…” button to set the value of these points.
6. Click “SETUP…” and do more detail settings, see Fig.

Program Org. [deg]: The program will consider this point as the program origin.

Axis Unit [Pulse/rev]: The pulse needed for rotary to move 1 round (must refer to the motor’s specification).

Speed [deg/sec]: The rotating speed of the rotary axis.

Backlash [deg.]: The transmission deviation between motor and axis.

Motor Reverse: Reverse the motor rotating direction.

Jog Reverse: When rotary axis is placed in the different direction with the software’s control panel, this parameter can make it rotate following the right direction.

Limit Trigger Level (0/1): 0: active low; 1: active high

Home Trigger Level (0/1): 0: active low; 1: active high

InPos Trigger Level (0/1): 0: active low; 1: active high

Acc/Dec Time [sec]: The time motor needs to reach the setting speed.

Init. Speed [mm/sec]: The initial speed of motor.

Inpos Timeout [sec]: The program will consider rotary axis completed position after passing the time setting here.

Inpos Delay [sec]: The program will wait for the setting time here to execute the next command.

Rotary Direction: Click to do further settings for the rotating direction of the rotary axis.

Method of Mark End: Five ways for laser to go back to the origin after finishing marking job.

• Reverse Direction: go back to the origin by backward direction.
• Shortest Path: go back to the origin by the shortest path.
• Reset As Origin A: set the mark end point as the new origin and the start point for the next marking.
• Reset As Origin B: set the mark end point as the new origin, but the rotary will move some distance (based on the distance of the object and the upper edge of software’s working area) and then start the next marking.
• Forward Direction: go back to the origin by forward direction.
• Please note that the origin represent different position according to the method of mark end. Only “Reset As Origin” method will consider the latest point as the origin, the other methods will treat the left-top corner of the work area as the origin.

Ext I/O Home: Using external controller (I/O) to do homing.

Ext I/O Jog+: Using external controller (I/O) to do positive shift.

Ext I/O Jog-: Using external controller (I/O) to do negative shift.

Home Speed [deg/sec]: The homing speed of rotary axis.

Home Back Speed [deg/sec]: The speed motor needs to move from home position to the edge of home sensor after reaching the home position (only for PMC2 &PCMark).

Home Reverse: Reverse the direction of homing.

Home Sensor Touching Mode (0/1): Decide that rotary axis will stop or do home in reverse direction when touching the limit sensor during homing. 0 is stop, and 1 is homing reversely.

Home End Point: Rotary axis will move to the assigned position (P0~P9) after homing.

Limit Stop Mode: Decide the motor stop rapidly (0) or slowly (1) when moving to limit sensor.

P0~P9 [deg.]: Set the position of P0~P9.

7. Click “XY-Table…” button can do X/Y Table control setting.
8. Click “Z-Axis…” button can do Z-Axis control setting.
