Since Inkscape outputs data using "relative" coordinates by default, this means that some designs that look just fine when viewed in Inkscape, Firefox, Chrome, etc, come out totally screwed up in Corel Draw.
This sucks - but it's not unique to Corel Draw - I've seen similar issues in both Firefox and Chrome web browsers. If this is a problem, the only work-around I have is to rescale the image in a paint program (GIMP/Photoshop/whatever) and re-import the image so that I don't have to rescale it.
Check the "Scale proportionately" box and make sure that "Apply to each object separately" is NOT set. The simplest way to do this in Inkscape is to use "Edit/SelectAll" then "Object/Transform." select the "Scale" tab, set the units to be "%" then enter 106.667 as the scale factor. To fix this (when exact dimensions matter), you have to scale everything by the ratio of the two PPIs - scaling everything up by 106.667%. Hence everything that you draw in Inkscape comes out about 6% too small in CorelDraw. So if you draw a 1 inch long line in Inkscape - it'll be stored as a 90 pixel line in SVG, which CorelDraw will convert to 0.9375" (90 pixels/96 ppi) as it loads it. Unfortunately, Inkscape uses 90 ppi and CorelDraw uses 96 ppi. In order to allow you to work in real-world units, programs have to assume some arbitrary number of pixels-per-inch (PPI) for the device you are using. However, the SVG standard requires that dimensions, positions, etc are stored in abstract units ("pixels") - not real-world units like inches or centimeters.

To be fair, none of these are Inkscapes' fault - but rather shortcomings in either the SVG file format, in CorelDraw or in the Laser Cutter drivers themselves.
However, there are a few "gotchas" to be aware of.

Since you'll need to transfer the files to the laser cutter's PC (which has a copy of CorelDraw) - this is no big deal. Hence if you want to do your design in Inkscape, you have to import the resulting SVG files into CorelDraw for lasering. Unfortunately, you can't drive the laser directly from within Inkscape because it rasterizes all of the vector data before sending it to the device.

One good/cheap option is to make your drawings in SVG format from " Inkscape" which is free/OpenSourced and runs well under Windows, Mac and Linux. But because Corel Draw costs $400 for the mainstream version and $99 for the student edition - you'll probably want to do your design work in some other piece of software. We generally operate the Blue Laser Cutter from within Corel Draw.
