I’m not sure where you are in your process. As the first step, I’d install Repetier-Host on your computer, configure Repetier-Host, and use it to move your machine around to verify all the steppers are working. Once that is done, you should run a crown test. Near the bottom of this page, under the Test File heading, you will find a link to download an already created g-code file of a test crown. You don’t need to install EstlCAM or deal with anything else on this page. The crown g-code file can be delivered to your machine using either Repetier-Host or an SD card (assuming you have a display).
Once you have your machine correctly drawing the crown, you can look at what to do with Carveco Maker. It appears that Candle is GRBL only, so you will be controlling/delivering your g-code to your machine using either the display attached to the control board, Repetier-Host, or some other g-code sender. As for Carveco Maker, you will need a Marlin-specific postprocessor. See this topic for links to at least one, though you should read the topic in detail. It appears there are issues to be worked around. It is also possible that in the year since the last post in that topic, a different or ungraded version of the Carveco Maker postprocessor has been created.
