text: <s>[INST] Rotary camming Summary: need help with cam I am fairly new to motion programming and I am working on a rotary axis project. I need to match position of the gearbox output and I have the cam created to do this and it works fine. I need to advance and retartd the slave in relation to the master and this is where I have a problem. I am calculating the cam on the fly, the cam is calculating correctly but when the pend mapc locks and is running the cam, the slave will run to the unwind and stop and reverse. I have the mapc set to continuous. basicly I am shifting the slave up one segment. I also program this cam table into a mapc and it does the same. can I not offset the cam in a rotary application? any help is appreciated! [/INST] It sounds like you have two problems? First, the cam doesn't run continuous in one direction, but oscillates? And second, you cannot offset the cam? The answer to the second is yes, you can offset the cam. Issuing an incremental MAM on the slave axis will offset it. Post your ACD file, let us take a look at it. The answer to the first question could be difficult to to solve without seeing your cams. \\n </s>
