 + 
 +Okay, but I have a Gerber file (that someone gave me, so, no, I can't re-export from Eagle/​KiCAD) and your laser takes DXF and I can't find a free Gerber to DXF converter. ​ What do I do? 
 + 
 +Simple! ​ (Not really, but it seems to work) 
 + 
 +  - Open the GTP file in Gerbv 
 +  - Export as PNG, 1016 dpi (this is arbitrary and is a leftover from a previous attempted workflow) 
 +  - Load PNG into GIMP 
 +  - Set DPI in Image->​Print Size.  Take note of dimensions in mm 
 +  - Colour->​Invert 
 +  - Colour->​Threshold (about 3/4) 
 +  - Select->​By Colour, click black 
 +  - Select->​Shrink Selection (5 seems to be good) 
 +  - New Layer, white background 
 +  - Fill (whole selection) with black 
 +  - delete original layer 
 +  - Export as PNG 
 +  - Load PNG into Inkscape 
 +  - Trace Bitmap 
 +  - delete bitmap 
 +  - Note dimensions in mm 
 +  - save as DXF 
 +  - Load into Smartcarve 
 +  - Set the dimensions
