Hi everyone I am new to the community and have recently become interested in CNC routing and woodworking projects. Before I get too deep into the hobby, I wanted to ask: what are the most important things a beginner should learn first?Are there any common mistakes with machine setup, tool selection, or project design that I should watch out for?Looking forward to learning from your experience. Thanks
A common mistake is worrying about perfection.
Don’t get hung up on the perfect machine setup or the perfect feeds and speeds before you start cutting. And certainly don’t get hung up on achieving the perfect end result right out of the gate.
Get to cutting and learning. You will develop a sense for what is important.
For every cool looking YouTube video there are many many failures and hours that went into it.
You want things to be good enough for you to start to learn and then you tighten up the machine and the process as you go.
Major things to focus on are workholding and dust collection. Don’t underestimate the power of that spinning bit to move the workpiece if it isn’t held down properly.

The biggest mistake is not reading/watching the documentation:
or failing to understand it and having a mismatch between Job Setup:
job setup:
and how origin is set relative to the stock:
Or failing to respect the machine and its limitations (wrong feeds and speeds, trying to cut through 2" thick stock w/ a 1" long endmill, trying to cut a too deep slot, &c.)
A couple of videos which touch on this subject:
You said it, experience.
You can not buy it, just do it and it will come.
Do small project, and then…

First off, welcome to the forum. All the advice posted so far is excellent.
Learn the machine - It’s important you know the X, Y and Z axis and relative movement.
Material holding - numerous ways to accomplish this. Ensure clamping of the material is sufficient.
Tooling (bits) - learn the difference between upcut, downcut and compression bits. They each have a purpose. V-bits, ball nose etc. have their purpose as well.
Router/Spindle - If you can get a spindle, do. They are quieter, vary RPM through your software based on your tooling and generally last much longer than the routers do. I know they are more expensive to begin with but they are worth the investment.
Software - I use Carbide Create and Carbide Motion. You are not limited to CC/CM, however there is a process to use other software. Just be aware of it.
Practice, practice, practice… - You can use CutRocket (C3D’s own site that has free files to use) or you can design your own. You can design basic projects and then cut them and make changes as you go to learn the process. This is one of the most important things for the new learner, practice on MDF or pine.
