Example: simplest possible linear cam for endlessly rotating processing

The table above with two slave position entries is the simplest conceivable cam description of a straight line in the form of a table.

The cam must be used endlessly in the positive direction. Otherwise, the dashed curve is run through.

In the case of closed scanning, the resulting straight line must pass through precisely the modulo range of the slave, i.e. it must have the pitch 1 as otherwise there is an abrupt position change at the modulo limit, i.e. with a straight line that has the pitch 1 as the cam a GearIn with the ratio 1:1 can be duplicated:

If you want to duplicate a GearIn with a straight line that has a pitch of 1, this is not possible with closed scanning!
