Go to the desired location in the map, set two markers by clicking the map to define a rectangle (or enter coordinates manually). Click the button [get data]. Optionally you can change the number of elevation samples you want in each direction, the more the better (max 400). You can also change the number of contours or set custom contour values. You can save some data in cookies, however there is a limit. Use the manual saving text areas below alternatively.

: One of the most reliable sources for the LaserDRW and CorelLASER installer is the OMTech Software Download Page . They provide clean, direct links for K40-compatible software.
Many users find the original Lihuiyu software limited. If you want a more modern workflow, consider these alternatives that work with the stock M2 Nano board:
: A standalone design and control application. It is basic but reliable for simple tasks like stamp making and direct engraving.
: During installation, you must select your specific motherboard model (usually 6C6879-LASER-M2 ) in the software settings to ensure correct motor speeds. Top Modern Alternatives (No Dongle Required)
: Some users find official files via the manufacturer's technical domains like 3wcad.com or cncu.co.za , though these sites may require translation. Installation & Hardware Requirements
Lihuiyu Studio Labs is the primary developer of the control systems found in the ubiquitous . Their hardware—specifically the M2 Nano and M3 Nano motherboards—is the backbone of entry-level laser cutting. To operate these machines, you need specialized software like LaserDRW , CorelLASER , or WinsealXP .
: You cannot run LaserDRW or CorelLASER without the physical USB dongle (often yellow, blue, or white) that came with your machine. This acts as a hardware license.
