Answer to "How to use scale in laser controls?"My solution on scaling: Think in pixels as your unit of measurement I was not able to scale large images down was my issue. After a call to BoXZY, I found out that the system works in pixels. Using Corel Draw, I changed my units there in pixels. No problems since on predicting what I will have when opening the image in the BoXZY interface. Formula to use: Inches × DPI = Pixels Use 250 DPI in your calculation here and don't forget that if you are dealing with metric (mm) values to divide those values by 25.4 before using the above formula. As for inside BoXZY, you can scale up, not down below the .1mm scale in the dialog box.
