arcYZ_Theta()

Posted by On 09 / 26 / 2019 0 Comment

Description

Draws a circular arc using a clockwise or counterclockwise arc. The direction is from the positive direction of the X axis where the circular motion occurs.
This method uses the center point mode to control the arc path, and uses the positive and negative values ​​of the rotation angle to select clockwise or counterclockwise.
For more information about various motion methods, please see the Motion Method Explanation page.

Syntax

machine.arcYZ_Theta(cY, cZ, theta); machine.arcYZ_Theta(cY, cZ, theta, feedrate);

Parameters

machine: Machine object.

cY: Y coordinate of the center of the circle in circle center mode.

cZ: Z coordinate of the center of the circle in circle center mode.

theta: The angle to be rotated. Use positive values ​​for clockwise and negative values ​​for counterclockwise.

feedrate: Feedrate. If no parameters are passed, the last recorded feedrate will be used.

Return

bool:

true: The machine exists and is created successfully.
false: The machine does not exist or fails to be created.

Example

Set the basic parameters of the machine and move the machine in a 90-degree arc on the XY plane.
