At the top of this page, under the ArtSoft banner you should see a box labeled Purchase. Click tha tbox and down near the bottom of the page that opens will be a purchase button. The wizards are called 'Add ons' and cost $50
You will be sent a license file by email. Save that file then copy it to the folder in which the MAch3.exe file is stored. On standard tormach installs I think that is C:\PCNC
Once the license file is loaded the wizards will save the gcode.
