Slider-Set 2
We will join the tool to the Belt at two separate 'anchor' Points, like Pins on a Chain.
In this Step, we use a new set of Piggyback Sliders to give the second 'anchor' point.
This Piggyback Slider Set is the same as the first set, but it runs before (ahead of, sooner than) the Master-Machine-Angle by 30º.
This means we can have 12 Tools along the length of the Belt. (360/30 = 12)
With this Piggyback Sliders. We can:
•Use again the horizontal Line in the Base-Part for the X-Slider.
•Use again the X and Y motions for the the X and Y Sliders.
NOTE: Remember - you can use the Motion-Path tool to add as many Motion-Points along the Motion-Path as you like. However, we do not have a Motion-Path in this Tutorial.
See Tutorial 16: Motion-Path FB and Blend-Curves

STEP 1: Add Sliding-Part, to the same Line as X-Slider1 STEP 2: Edit the new Sliding-Part, Add a vertical Line. Close the Part-Editor STEP 3: Add a Sliding-Part to the vertical Line STEP 4: Add a Motion-Dimension FB to the Sliding-Part that moves along the horizontal Line - rename it to X-Slider2 Tip: When you select the Slide-Joint as the first element for the Motion-Dimension FB, it not easy to identify the 'narrow rectangles' on the Line in the Base-Part as they are identical. It is easier to identify and select the 'wide rectangle STEP 5: Add a Motion-Dimension FB to the Sliding-Part that moves along the vertical Line - rename it to Y-Slider2 STEP 6: Edit the Base-Value of the new Motion-Dimension FBs to the same as the First set of Piggyback Sliders Tip: Do ALT+F a number of times to move the first Slider-Set along the Belt path. |

STEP 1: Add two Motion FBs STEP 2: Edit the Motion FBs: couple one to 'X' motion, and the other to 'Y' motion - see Step 15.1 STEP 3: Rename the Motion FBs correspondingly to X2 STEP 4: Add a Gearing FB STEP 5: Edit the Gearing FB STEP 6: Connect the existing Linear-Motion FB STEP 7: Connect the Gearing FB to the two Motion FBs STEP 8: Connect the Motion FB called Y2 STEP 9: Connect the Motion FB called X2 The two Motion FBs at the bottom of the image When you cycle the mechanism, Slider2 set is in front of Slider1 set by 30º of the MMA. There are two sets of Sliders: Slider-Set 1 and Slider-Set 2. Each Slider Set can trace out the path of the Belt. See: Add menu > Mechanism sub-menu > Add Trace-Point |
