Murphy's Law: Workbed Prep and Positioning Materials for Laser Engraving

Hey all, Murphy here with another iteration of Murphy’s Law! Today, I’ll show you the secret to getting the best out of your laser engraver/cutter: proper bed preparation and precise material positioning. 

These techniques aren’t just extra fluff—they’re the backbone of achieving the ultimate, picture-perfect engravings that’ll blow your friends and family away. So, buckle up and get ready to transform your laser engraver into an ultra-precise, reliable machine!

Why a Well-Maintained Bed is Your Best Asset 

With your laser engraver’s working bed as the canvas, you’ll want to ensure your work area is primed and ready for production. Imagine trying to write on a crumpled piece of paper; it probably won’t result in your best work. The same goes for laser engraving. 

A clean, level, and well-maintained workbed ensures you’ll have consistent focus across the entire area, even power distribution, reduced risk of fire or damage, and improved quality of your engravings and cuts. In short, a stable bed means stable engravings! 

Preparing Your Laser Bed for Optimal Performance 

Maintaining your laser engraver doesn’t have to be a lengthy or strenuous project. In fact, only some tasks, such as clearing the working bed, should be done daily. Other maintenance can be done weekly, biweekly, or even monthly, depending on how often you utilize your laser engraver.

Here’s how to prepare your laser engraving bed for optimal performance: 

Safety first: Always make sure your laser is powered off and cooled down before cleaning. 

Debris removal: Use a soft brush or vacuum to gently remove particles from the working bed. Remember to also clear out the debris tray underneath the machine to get rid of any other crumbs. 

Wipe down: For residue, use a microfiber cloth and a mild, non-abrasive cleaner to wipe down the surface. For persistent burn marks, I recommend using a degreaser to get out those workbed stains. 

Ensure Your Workbed is Level 

A level bed is crucial for consistent results. If your working bed is even a couple of millimeters off, it could alter your final products drastically with out-of-focus engravings. Therefore, if you want your products to look sharp and accurate, make sure your work area is level. 

• Use the level that comes with your machine to check the bed’s alignment in multiple spots. I suggest you check all four corners of your working bed with your level or any other object with a sizable width. 
• If your bed isn’t level, you’ll need to adjust the bed’s legs as needed. You can use an Allen key to unscrew the legs underneath the bed and adjust them. Make sure to recheck with the level after you’ve adjusted the legs. 

Material Positioning Fundamentals 

Once your working area is primed and ready, you’re ready to position your materials. Proper positioning ensures your machine is optimally focused, consistently delivering power, and efficiently utilizing materials. With accurate positioning, your laser engraver will deliver higher-quality results with less material waste. 

Positioning Techniques for Various Materials 

Flat Materials

Working with flat materials like acrylic sheets, wood panels, or leather? If you’re working with thin wood that has a slight bow or materials that are prone to warping, utilizing honeycomb bed pins or magnets keeps your projects in place.  

Cylindrical Objects 

A rotary attachment is a must-have for those working on tumblers, wine bottles, or other cylindrical objects. Rotary attachments hold the item in place and turn it during the engraving process, allowing you to achieve 360-degree designs on irregular-shaped products. Our CO2 laser engravers, from our mid-range models to our desktop models, accommodate rotary attachment to add more variety to your engraving arsenal!

How to Align Materials in Lightburn

Before you position your materials, ensure that your mirrors are aligned as well. This will make sure your laser head is accurate before you start the alignment.  

• Using the Square tool on the left-hand side, draw a square on the template. Then click the cursor tool and make sure your square is the same dimension as the material you’re engraving or cutting. 
• Center the square wherever you want to engrave on the working bed. Select a color in the bottom left to designate the pattern as a burn layer. 
• Find the center to align the pattern by designating the job origin. We prefer to use the center, but you can also opt to position the job origin however you want. 

• Click on the Move tab and ensure the Fire button is there. If you don’t see the Fire button, go to Edit on the top left and select Device Settings. Turn on the settings for the “Enable laser fire button.” 
• Select the Location button on the left side. This button sets the laser position on the page. Click the center of the square to select where the laser will fire. Then press Go and watch the laser beam appear on your workbed.

• Place your material on the workbed and center it with the laser beam. You can also use the Frame button on the right side to outline the pattern of your material. This will keep your virtual pattern in line with your actual working equipment!
