Welcome to the forum!
Getting a grasp on what you are getting into is a good idea.
-CAD side: We had many users expecting to find ready made files that they could just load and cut.
This is rarely the case, because material thickness, bit diameter and other stuff is just not transferable from one machine to the other, unless all parameters are identical. So learning one of the CAD options is a must, as well as entering the correct settings to convert the drawing to g-code (CAM).
If you start learning how to adjust files to your requirements, you might as well design them from the scratch.
At the end of the day you will want to know how to cut you own projects.
-Hardware side: The MaslowCNC is not a ‘plug and play’ device. It takes some dedication to get though the setup and calibrate the machine. The frame needs to be built and router and ‘chain link’ need to be attached to the sled. Precise measurement and drilling skills are required.
The support on this Forum is the best I’ve seen, so there is help if you get stuck.
