In some cases, GPP2 has to stop the cutting motions in the middle of a 5X segment, and rotate the machine to another equivalent position before continuing with the toolpath.
GPP2 identifies the need for such connections automatically, and handles them without any help from the EX2 program. However, the shape of the connection may be controlled as explained below.
These connections are only needed for machines with hard limits on their axes. GPP2 will apply a 5X connection in one of the following cases:
Switch to Other Solution: Many times, there are two solutions for a given orientation of the tool. When the solution used reaches the machine angle limit, it is often possible to switch to the other solution and continue the operation.
Rewind Axis: Sometimes, there is no other solution (For example, on a 4X machine), and the axis must be rewound one or more full rotations before cutting can continue.
Find Middle Point: In rare cases, it is not possible to switch to the other solution at the current tool point (that solution is not valid), but it is also not possible to continue to the next point without doing the switch. In such a case, GPP2 will find a middle point, between the current and next points, where both solutions are valid, and the swap may be done. This is done by GPP2 automatically.
