Step 15.3 New Slider Set - Different Phase

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)

There is far less to model that the first Piggyback Sliders. We can:

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

Add Piggyback Sliders - Slider Set 2

Add the new Sliders:

We give names: X-Slider1 and Y-Slider1 to the Sliders we added in Step 15.1. Here we will add two new Sliders, We will rename them to X-Slider2 and Y-Slider2.

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' on the moving Part. 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: Use Step forward a number of times to move the first Slider-Set along the Belt path.

Add the Function-Blocks

The two Motion FBs at the bottom of the image are connected to the existing X-Slider and Y-Slider.

STEP 1: Add two Motion FBs STEP 2: Edit the Motion FBs: Link one to 'X' motion, and the other to 'Y' motion - see Step 15.1 STEP 3: Rename the Motion FBs correspondingly to X2 and Y2 STEP 4: Add a Gearing FB STEP 5: Edit the Gearing FB. Edit the 'After Gear Ratio' parameter to 30 STEP 6: Connect the existing Linear-Motion FB to the Gearing FB STEP 7: Connect the Gearing FB to the two Motion FBs STEP 8: Connect the Motion FB called Y2 to Y-Slider2 STEP 9: Connect the Motion FB called X2 to X-Slider2 When you cycle the mechanism, Slider2 set is ahead 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 Point-Trace
