yeah you could just have bought something better, for less money that didn't need uopgrading so much out of the box.

Anyone recommending ender series printers need locking up.

Okay, what it does need is: converting to directdrive extruder, adding a second z-motor (assuming the pro still has just the one). And some side support rails would be a good idea too.
Sounds like you've already replaced everything else :-)

Also if you primarily intend to print miniatures, why not just get a cheap resin printer ?
Why get a large print volume machine that keaves the factory needing all it's original parts replaced ?

I wish you luck - but most people who buy ender printers do seem to regret it.
