I want to print nylon and carbon fiber on Ender,..HELP Please

All the reviews out there hard to tell some are years old. The new S1 looks good but dont trust the head and would have to upgrade. The body looks great well desgned.

So do I just get the 3 V2 or go with the 5 and upgrade. Price is not a huge concern but dont want to get crazy I know a new hot end should be needed as well as a good heated bed.

Sold the Markforged line so I know enough to be dangerous. But that is a very closed system and expensive. Been a cnc machinst/programmer in another life now I am just older and want to build ot my own shop in the garage.

I want to print strong parts and try to make a better MPCNC.

​

Thanks in advance
