If you don't already have the latest version of Cura, you can get it here:

https://ultimaker.com/software/ultimaker-cura

Beta version 0.4 of the profiles can be found here : https://cdn.hackaday.io/files/1871448006768896/Ender3LuckyBotProfilesVer0.4.zip

The Zip file contains all the files needed to create a new "Ender 3 Pro LuckyBot" printer and extruder profile.   Each file goes to a different location as follows.  If you are on Windows 10/11 with Cura 5.1.0 it probably looks something like this:

copy /y chocolate.xml.fdm_material                 "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\materials\chocolate.xml.fdm_material" 
copy /y creality_ender3pro_luckybot.def.json       "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\definitions\creality_ender3pro_luckybot.def.json"
copy /y creality_base_extruder_0_luckybot.def.json "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\extruders\creality_base_extruder_0_luckybot.def.json"
copy /y creality_ender3_luckybot.3mf               "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\meshes\creality_ender3_luckybot.3mf"
copy /y base_global_standard_luckybot.inst.cfg     "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\quality\creality\base\base_global_standard_luckybot.inst.cfg"
copy /y creality_ender3pro_luckybot0.84.inst.cfg    "C:\Program Files\Ultimaker Cura 5.1.0\share\cura\resources\variants\creality_ender3pro_luckybot1.0.inst.cfg"

Now that Cura is updated, you simply need to add the printer.  Click the pulldown for the machine and select "Add printer"

Select "add a non-networked printer" and then expand the "Creality" group.  Here you will find a new "Creality ENder-3 Pro with LuckyBot".  Select it and then click the Add button.

You should now see the window below with the "LuckyBot" extruder showing up.  This contains the custom Gcode and offsets.  Note that if you did not use the Creality extender, your build volume will be smaller than this. You can change it here. Click Next

If all the files were copied over correctly, you should now see your "Creality Ender-3 Pro With LuckyBot" printer, a "Chocolate" material, and a "LuckyBot Standard" print profile.  You can modify the profile for your own options. Right now, it defaults to 40% infill using lines and a "brim" around the part to prime the chocolate.  

This is just an "Alpha" version. If you see bugs or have suggestions, click here:

I can only create profiles for the printers I have.  If you modify the existing profiles to work with your own setup, I'd love to add them.  Just reach out.  Even better, if you know git and cura come join me here: https://github.com/burhop/cura-luckybot
