28 kwi 2024 · Syntax for G68 Coordinate System Rotation (Fanuc & Mach3) The syntax for a G68 is pretty simple. For Fanuc, use: G68 <alpha> <beta> R<angle> Where, alpha and beta are words for the 2 coordinates of the circle’s center we want to rotate about. For G17, <alpha> is X and <beta> is Y. In the example, we had the circle center at X0Y0.

The G68 command (G-code) is used to perform rotation of the coordinate system by a certain angle. X and Y are the coordinates of the point relative to which the coordinate system will be rotated, and R - determines the value of the angle of rotation.

When you command a G68, the control rotates all X, Y, Z, I, J, and K values about a center of rotation to a specified angle (R),. You can designate a plane with G17 , G18 , or G19 before G68 to establish the axis plane to rotate.
17 sty 2022 · After you load the .obj into Rhino, you will see that the 3d map piece is rotated. To rotate the piece back, I figured you need to rotate around -longitude seen from the top, then 90-latitude seen from the front, and -90 from top again, and you have your piece perfectly leveled.
