Well, there you have it! A starting guide on how to find the right speed vs power settings for your laser cutter.

As you can see, finding the right balance really isn’t that hard and all it requires is a little trial and error. Speed and power have a delicate balance and there are only a handful of combinations of both that will produce the best results. Alternatively, you could adjust your laser’s z-axis for darker results. If all of your squares are too dark at high speed, then you can try lowering the speed until you find your desired engraving. Look for things such as how many different levels you have and how they transition. If a box is 50% gray, then a 50% output will be used. The different shades of gray will output various engraving power in the laser.
Start with high cutting speed and begin engraving. Instead of making one yourself, I would suggest downloading one from Thingiverse.Ģ. Create the same grid as the method above, except this time, the squares will have to be outlined and filled in different shades of black. The test is basically the same as the laser cutting one but using the grayscale method instead. To find your desired darkness, we need to use the right amount of power and move fast enough to ensure that we only affect the surface. If you are unable to produce your desired edge quality, then you might have to look into some other parameters like the number of pass-throughs. If you want to test even further, you can test in the range of the best results with smaller increments.įor instance, if 50%/60% power and 50%/60% speed were the best, then you can test the numbers in between that (like 51% then 52%, etc.). When the test is over look for the squares that are completely cut, with straight edges and no char. Assign the outline of each square in your matrix according to colour. In your laser cutting program, assign each colour a different setting. Name the y-axis ‘power’, and match each row with the percentage tested.ģ. Name the x-axis ‘speed’, and write the percentage tested on each column. You could get this done within 8 copies and pastes.Ģ. 10×10 for 100 combinations) making sure to leave some space in between them. In your drawing program, create a grid of unfilled boxes (e.g. This will determine how many combinations you will test (100 combinations are usually tested to find an acceptable zone). Determine how accurate you would like to be. To penetrate the material entirely and cleanly, we need to have enough power to cut deep and enough time for the laser to penetrate. Make sure to keep your results! Cut out the grid and keep it somewhere so you can always refer back to it! Laser Cutting Matrix Test The best thing about this test is that you only have to set up most of it once! That’s why in my guide on Laser Cutting Materials, I intentionally excluded specific speed and power settings. Whenever you use new materials, you should use this test on it because every laser cutter will react differently.
While they can be useful, you should still test it out for yourself. You can find many charts online with predetermined settings, such as this one. There is a quick test you can use to find the best speed and power settings for your cut. How to Find the Perfect Speed vs Power Setting Getting within the range of an acceptable balance isn’t as hard as you think. With power and speed levels ranging from 1-100, there are 9801 different combinations to use, with one that is optimal and a hundred more that are acceptable. But don’t worry, most of the time we’re looking for more of an acceptable balance, rather than perfect. The Delicate Balance Between Speed and PowerĪs you can tell, there is a delicate balance between speed and power. Going too fast or too slow could result in undesirable edges. Lower speed = slower cutting = deeper cut Higher speed = faster cutting = shallower cut
