After fixing the rails, immediately add a stopper between the front of your frame and the carriage (cable tie). The carriage can escape the rail on the front.
For the z rails i think it's ok to remove only one stopper. In the next step insert the rail with the stopper facing bottom into the frame. It makes the handling much more convenient and safe.
Before you begin to install your frame, have a look at this video to understand the importance of squareness and how to archieve it: https://www.youtube.com/watch?v=h7ZTq2dD...
I found it difficult to get the magnets flush with the printed part, but this worked for me:
1) Widen the magnet beds a little bit with a 10mm drill if it is too tight.
2) Clean the magnet beds from leftovers and overhang print artifacts (especially for the frame magnet mounts)
3) Fit the magnet, check its orientation, and press it in with a screw clamp. (it does not have to be perfectly flush right now). A non-metal clamp makes your life easier.
4) Take a spare M3x25 cap head screw and place it onto the magnet with the head-side sticking to the magnet.
5) If the part you are working with is a frame magnet mount, fix it with another clamp to your workbench.
6) Carefully hammer and reposition the screw and press the magnet flush into it's bed.
Attention: Neodymium magnets are quite fragile and should not be hammered with force or gripped with pliers. They will split in many little sharp shards sticking to your tools, furniture and computer. Take care!
As my parts have a tight fit, i recommend installing the bearings now

In case the pins sit too tight, carefully drill (3mm, very low speed). You still want it tight!
