How is rq_ignore_snapshot_pos() used to offset the snapshot position so stacked parts using the parametric teach mode are found?Using the "Manage Stacks - Application Package" as a starting point, I have a program that is supposed to locate and pickup grinding wheels taught as a parametric with dimensions 152,75,52. At the bottom layer, the camera locates the part no problem. with a stack, the camera never locates a wheel. (threshold is 45%, teaching gets over 75%). I guessing the camera is calculating two stacked wheels as a single wheel with a height of 104, and therefore not detecting/locating.The "Skills_Camera_Add-On.PDF" states, "It can be used to offset the snapshot position when managing stacked parts..." but that document does not offer any examples of how or what to do to make that happen.
