First, I measured the trackpad with my digial calipers. It was 2.9" x 1.7"

Then I opened up this dxf Hack-A-Day logo, filled in the color and scaled it to fit.

To fit the machine in the laser cutter without disabling any of the safety interlocks, I removed the display. On the E1705 it's just a bezel cover, four screws, the keyboard (two more screws), and the wireless antenna cable (two screws on the back cover to access).

I did a test run on some paper, then ran the job twice at 100% speed and just 15% power. I didn't want to damage the pad, so I went pretty low. To align it, I used my calipers to find the center of the touch pad and manually set the center position to it.
