After you get it assembled, try using the quick draw pen and some cardboard that came with your 5 pro to see if things are good with the machine. (a place to start)
Then do some test cuts with scrap wood and see how that turns out.
As pointed out by @WillAdams .
Not all problems are machine related, as in this post the compact router had quite a bit of runout.
There can also be issues with work holding, if not clamped tight the piece can move during machining this would not be machine related.
These are just a few things that come to mind.
Hope this is helpful.
P.S. Welcome aboard and have fun with your new 5pro.
