Now click on the second box and with the Shape Properties box open, adjust the Power Scale to 90%.
Open Window and click on Shape Properties to add the Shape Properties box on the right-hand side.
Scratch paper full#
I take full responsibility for what I put my own machines through during testing). (Please note that it is not advisable to run the laser at more than 80% without running a risk of shortening its working lifespan and so on. I started with 1500 mm/min for speed – I’ve worked with paper before and almost had a little fire, be careful, do not use high power and slow speeds on flammable materials such as card or paper! First box 1500 speed 100% power. I used 9.Ĭlick on the first box and set the speed and power. This opens the Create Grid Array box, change the X columns to the number of power settings needed to test. It shows the different “layers” on the Cuts/Layers box on the right-hand side to match with all the boxes on the work area.īut what if you needed to test more settings at the same time, can it be done? Yes, it can! Using the Array Function in Lightburnĭraw a square with the rectangle tool on the left of the workspace. So, I drew up my own version of a test as below: Running a test like this would mean that you could have a maximum of 29 different settings of speed and power – aha easy really.
It appeared that on most of the ones I looked at, the bottom left-hand square related to one speed and power, the next along the same speed and a lesser power and so on, so why had I found this complicated? There was a bit of a lightbulb moment when I realised that each box would need to be assigned a different colour in Lightburn to signify each different setting (i.e., layer). So, it was time to pull it apart and see what it really does. Laser Testing Gridsįirst of all I’ll be completely honest here, since I’ve had my laser, I have repeatedly looked at “Test Grids” being used and I just didn’t get it I’m afraid, I am blonde admittedly but I’ve got to grips with most things but these grids just looked so complicated and I couldn’t seem to find an explanation of what they were supposed to achieve and how. This article is going to look at testing grids, using the array function in LightBurn, burn tests on scratch paper, burning an image on scratch paper and cleaning the image for display. Go raid your kids or grandkids' craft boxes if they have them or splash out and get a huge pack for about $30 / 20 GBP. Well, if you haven’t seen photographs of it done yet, you can get great results using your laser on scratch card or paper and the YoraHome CNC Laser Engraving Machine 6550 is the ideal machine with its laser to try this out. Who didn’t love scratch paper when they were little? Even the least artistically blessed could be proud of the colorful scratches they made on pieces of black card.
