Head RTCP

Head RTCP applies to machines with a rotating head (one or two axes are in the head). If supported, the machine controller will adjust the tool position with every rotation of the head, as demonstrated in the figure below.

Assume the tool is located at position 1, and needs to be rotated at an angle but still remain at the same tool tip position. Rotating the head without any correction would result in position 2, far away from the desired tool tip position. The spindle position must be corrected (moved to the right) in order to reach position 3.

With Head RTCP, it is the controller that handles the position correction. Without Head RTCP it is GPP2 that does the same.

For machines with Head RTCP, the M5_RTCP_HEAD variable has to be set to TRUE_. For machines without Head RTCP, it has to be to FALSE_. The variable can be set dynamically during the run - GPP2 will adjust its output accordingly.
