1. Easle
Easle is a web gcode creator. You upload your svg there and also manipulate it. You can also send gcode directly to your machine as we used to do it for our stepcraft machine.

The sled files you can find here https://github.com/MaslowCNC/Mechanics/blob/master/SVG%20Files/SledFiles.zip
2. Makercam
I have not used this yet.
