Overview

The Cut Line feature allows you to temporarily block the FieldPrinter from printing beyond a defined boundary. Cut lines are commonly used to control where printing occurs when parts of the slab are not ready, unsafe, or obstructed. Think of a cut line as a temporary, digital barrier that the robot will not cross during printing.

When to Use a Cut Line

Use a cut line when:

• A portion of the slab is obstructed or not yet ready (wet concrete, ongoing work, missing edge protection).
• Materials, embeds, or equipment are staged in one area and cannot be moved.
• You want to print one zone now and return later to complete the rest.
• You need a mini boundary to prevent accidental printing into an unfinished or restricted area.

Do not use cut lines to fix stationing, control, or accuracy issues.

How to Create a Cut Line

1. Open the editing tools
   • On the tablet, open the tool menu used for drawing or modifying layout elements.
2. Select the Cut Line tool
   • Choose Cut Line from the available tools.
3. Draw the cut line boundary
   • Draw a line across the area you want to block.
   • The cut line should fully separate the printable area from the restricted area.
4. Confirm the cut direction
   • Ensure the cut is applied to the correct side of the line.
   • The robot will only print on the allowed side of the cut line.
5. Verify behavior on the canvas
   • Confirm that layout geometry beyond the cut line is no longer eligible for printing.

How to Use a Cut Line During Printing

• Print the ready area as normal.
• The FieldPrinter will stop at the cut line and will not cross into the restricted zone.
• When the blocked area becomes ready, remove or adjust the cut line and resume printing.

Best Practices

• Use cut lines as temporary controls, not permanent edits.
• Place cut lines in simple, straight locations to avoid confusion.
• Remove cut lines once the area is ready to avoid accidentally skipping layout.
• Cut lines will not correct model or control errors.

Common Mistakes

• Using a cut line to hide incorrectly prepared layout.
• Drawing a cut line that does not fully block the intended area.
