KastoWin Saw: Troubleshooting Stuck Round Bar Products

The KastoWin saw stops the round bar because the upstream source creates a basic component, while the saw routine requires a product with a defined product type. Replace the Basic Feeder with a feeder from the pm flow components category, configure it to create the required product, and select SRB in the saw’s Cutting Orders list. The routine can then recognize the incoming bar, match it to a cutting order, and advance beyond its first step.

Identify the Object-Type Mismatch

The visible symptom is a round bar that enters the saw but remains there while the routine shown in the process tab never reaches its second step. This behavior points to an input qualification failure rather than a conveyor-transfer problem. The saw receives geometry at its entry, but the received object does not expose the product information its internal process expects.

A basic component and a product can look identical in the 3D model while behaving differently in process logic. A basic component primarily supplies geometry and physical presence. A product participates in material-flow processing and carries the product-type identity used by machines, routing logic, and production orders. Passing the correct shape into the saw therefore does not prove that the correct process object has arrived.

The decisive correction is to generate products rather than basic components. The saw also needs a cutting order whose product selection matches the arriving product. For this model, use SRB in Cutting Orders.

Understand Why the Routine Stops Before Step Two

Material-flow machines commonly qualify an incoming item before starting their processing sequence. The qualification stage checks whether the object is a supported product and whether an applicable order exists. Only after that match can the machine associate the item with a process recipe and continue through its routine.

Because the input is physically present, repeatedly increasing conveyor speed, repositioning the bar, or extending simulation time will not resolve this mismatch. Those changes affect transport, not the product identity evaluated by the saw.

Build the Required Material-Flow Chain

The overall arrangement remains valid: feeder, input conveyor, KastoWin saw, and output conveyor. The required change is the type and configuration of the feeder, not the basic topology.

1. Use a feeder capable of creating products from the pm flow components category.
2. Configure the feeder to generate the product expected by the saw rather than an untyped basic component.
3. Connect the feeder to the input conveyor and the input conveyor to the saw.
4. Connect the saw output to the downstream conveyor.
5. Open the saw configuration and add or select SRB in the Cutting Orders list.

Keep product identity consistent across the entire chain. The feeder’s generated product type and the saw’s cutting-order product selection must refer to the same type. Visual similarity is irrelevant to that lookup: renaming an ordinary component or giving it round-bar geometry does not necessarily convert it into a process-aware product.

Run the Diagnostic Sequence

1. Inspect the saw metadata. Open the machine metadata and review its How To Use information. Treat this as the component’s interface specification: it identifies the expected upstream object class and required order configuration.
2. Inspect the feeder category. Determine whether the current source is a Basic Feeder or a product-producing feeder. If it is a Basic Feeder, the object-class mismatch is already identified.
3. Inspect the generated object. Confirm that the emitted round bar is a product and that it has the product type required by the cutting order. Do not rely only on its name, color, or shape.
4. Inspect Cutting Orders. Confirm that SRB is selected and that the order applies to the product produced upstream.
5. Observe one item. Run a controlled test with one product. Watch the process tab from arrival through cutting and discharge. A single-item test prevents queued bars from obscuring the first failed transition.
6. Separate processing from transport. If the routine advances but the finished item does not leave, then inspect the downstream conveyor connection and availability. If the routine still stops before step two, return to product and order qualification.

This order of checks follows the control path: machine requirements, source capability, product identity, order match, internal sequence, and finally downstream transfer. It prevents transport adjustments from masking a data-model problem.

Apply the Fix Without Rebuilding the Model

1. Stop or pause the simulation at a clean state.
2. Remove the Basic Feeder from the active flow path, or disconnect it while retaining it for comparison.
3. Add the appropriate product-producing feeder from pm flow components.
4. Configure that feeder to create the round-bar product required by the application.
5. Reconnect the feeder output to the existing input conveyor.
6. Open the KastoWin saw settings and configure SRB in Cutting Orders.
7. Clear any previously trapped basic component from the saw before restarting the test. An object already created by the old feeder retains its original classification.
8. Start the simulation and release one newly created product.

Replacing only the feeder while leaving an old bar inside the machine can make the correction appear ineffective. Test with a newly instantiated product so that the object comes from the corrected product-producing source.

Verify the Repair and Avoid Recurring Pitfalls

Verify both control execution and material transfer. In the process tab, confirm that the routine advances from its first step to its second step after the new product arrives. Then confirm that the saw processes the bar and transfers the resulting output toward the downstream conveyor.

Use the following acceptance checks:

• The feeder creates a product, not a basic component.
• The product reaches the saw without becoming detached from the intended flow path.
• The saw recognizes the product selected by SRB in Cutting Orders.
• The routine advances beyond step one.
• The processed output leaves the saw and enters the downstream conveyor.
• A second product completes the same sequence, proving that the first success was not caused by a manually cleared state.

Recurring mistakes include selecting a feeder by visual behavior alone, assuming geometry determines machine compatibility, and troubleshooting conveyors before checking product metadata. Another common pitfall is configuring a cutting order but producing a different product type upstream. When a specialized machine captures an item yet its routine remains at an initial step, inspect product class, product-type matching, and order selection before modifying physical layout.
