The gcode generated for simple shapes is being filled. I just wanted to get the gcode for the boundry .

I'm trying this code for the first time and the output looks correct except for being scaled up greatly. The output is too big by a factor of 37.566. Any idea what could be the issue?

When I ran npm install -g svg2gcode in Terminal I received a long error:

Could you help identify what I've done wrong? Thanks.

The README doesn't match the output of -h.

sorry to open ticket for my question but actually I'm looking for light gcode visualizer or probably cad2gcode convertor in my webpage , but this webpage hosted on tiny ESP826612F module which is connected to Arduino GRBL gcode interpreter by serial line, so I should have great care about its weight , My plan is just connect to wifi module and open the browser and do designated CAM job.,As I'm not pro in client side script like JavaScript I was hopping could have good advise here, do you suggest to make some plugin from such library so I shouldn't have to download or call all library ?
thanks

After finally getting Cairo installed everytime I put an svg through, it just gives gcode for a square pattern (small square, larger bounding square, repeat)..

This is my command

svg2gcode -t 3 -c 4 -d 3 -D 1 /Users/brod/Desktop/test.svg

Any ideas?

Do getPoints first, keep track of the bounding box, then use the abs max of the limits to determine an integer scale. This approach shouldn't require any tolerances to account for the divisions because we are working with the actual nominal curve instead of the theoretic one.
