Print the Smooth Curves Stencil Design


This article has instructions for printing a fast and easy diagnostic print. We call it the Smooth Curves Stencil, and it’s designed to test many different types of Glowforge behavior, from head speed to focus calibration.

If you’re having trouble printing with Pro Passthrough, you’ve probably already been asked to print this test pattern.

If you haven’t already contacted us, but your Pro Passthrough print didn’t align quite correctly, please do this test print and then send email to Glowforge Support. Printing this in advance makes it much faster for us to diagnose what’s going on with your Glowforge.

When you follow these steps and then tell us what happened, it gives us a lot of good information that will help us get the problem fixed.

And bonus, even when it’s not a test, it’s a really cool print! This stencil is a much-loved everyday tool for drafters, illustrators, and designers.

Get the design

Go to the Smooth Curves Stencil at and get the design. You’ll follow the same shopping cart check-out process as to purchase a design, but since the design is free, there’s no charge.

Print the design

  1. Place a sheet of medium draft board into the Pro Passthrough slot longways and ensure that the portion sticking out of the printer is supported so the material lies flat on the crumb tray inside the printer.
  2. Double-check that the material is completely flat against the crumb tray. A quick way to do this is to press gently on the material where it rests on the tray and feel if it moves. If it’s flat, it shouldn’t move.
    Note: It can help to use pins to hold the material flat against the tray. For example, a lot of customers use small pieces of scrap to print these pins available in the free laser design section.
  3. On your Dashboard, open the Smooth Curves Stencil design.
  4. In the workspace, open the 3 dot More menu, and make sure Pro Passthrough is turned on.
  5. Select the entire design, and arrange it so that the tips of the arrows touch the dotted line at the top of the work area as shown below.
  6. Place your material on the printer bed, and select the type of material in the top left.
    1. Click print and run the first section of the design.
    2. After the first section completes, your Glowforge will inspect the design and take pictures to help with the alignment in the next step of your print. Please do not move your material or open the lid until prompted by the onscreen instructions.Second subsection
    3. After your Glowforge has taken pictures to help with the alignment of your design, follow the onscreen instructions and move your material through the Pro Passthrough slot so the printed area is more than 3 in (7.6 cm) away from the front of the Glowforge.
    4. Follow the prompts and run the 2nd portion of the test print.


  7. If you are working with the support team on a specific issue, once the test print is complete, please reply to the email from support and send us photos of the front and back of the finished print along with the date and time when you printed it.

  8. If you haven’t already, please contact Glowforge Support and include the following information:
      • Any photos you took during the troubleshooting steps above.
      • A description of the trouble, including any screenshots you have from the app.
      • The approximate date and time the problem began.
      • A copy of the design file you were trying to print.

Once we have photos of your diagnostic print, We’ll review everything and follow up with next steps. Thank you in advance for running this test – it makes it much faster for us to get you the answers and fixes you need. You’d be amazed at how many mysteries are solved by a simple photo of a squiggly curve.
