Im looking on the Maslow website, under the guide step 5.
In step 8 it says the Design files for the sled can be found in the file section.
I download the file, has an awful lot of photographs and other non opening exe. but no NC of GCode?
Can someone point me in the right direction please?
Thank you for pointing that out. I will look into it right away. In the meantime I recommend this one as an actually better alternative:

You are right that there is not currently a gcode file in there for the sled. I will add one right away 
I’ve created a pull request here to add a ready to cut gcode file
Many thanks, I will use the recommended.
