Congratulations! From a side of printing that's heavier-duty and plays with engineering materials more, have some knowledge:
- PLA+ != PLA. PLA+ is a monster of a plastic blend that'll do a lot of heavy-duty things provided you keep the heat light
- Carbon fiber is not what makes a plastic strong. Treat CF blends individually -- Nylons are usually pretty good structurally, PLA-CF less so
- Moisture content has a huge impact on print quality. +1 for a good filament dehydrator
- Keep yourself safe. Do not sand or cut filled plastics (-CF, -GF, etc.) without PPE! Don't be the example case for new-age asbestos lung

Yeah, the link on the Index seems to still be live from over here
