I recommend pressing the screw all the way into the plastic part, so that the screw head is almost aligned with the plastic (On some parts you have to apply some force here, as they have manufacturing tolerances).
Then screw the T-Nut onto the screw by JUST ONE turn.
Now place the part on the printer and tighten the screw SLOWLY.
Observe that the T-nut rotates 90 degrees. If not, DO NOT tighten, try again instead.
You have to remove the head from the "Phaetus Rapido V2 UHF Hotend" (secured by 2 screws). I think this step should be mentioned in the documentary.
Insert a screw in every second hole (like shown in the third image).
The Text sholuld be corrected.
The first image "6x M3x8 Cap Head Screws" seems to be wrong for this step?
You need 3x pillow_block printed part (green arrow), not 2. It is shown correctly in the image.

The plastic parts break extremely quickly when tightening the M6x12 screw. Be realy carefully!!!
It seems that the images are still wrong.
