I'am using the creality cr-10 s4 and i love it.
The size of the prints are massive and i almost dont have to cut the prints.
The part i love most is the strait forward way of use, its just plug and play and there's not much that can go wrong.
The only con is the out of filament sensor, i didnt find a way to make this work, its pauses my prints every 10 min or so so i had to remove it.
As a slicer i use Simplify 3d.
Yes i know you have to pay for it (lucky i got it from work).
There a so much features and tweeks you can do it can be overwhelming.
There are so much features on this!!! you can modify everything to your liking!!
I found out it works even better then cura (witch is an amazing program).
When you are printing more parts a the time you can modify your print program to every print part so they come out perfect.
And the way the supports work its simply awesome.
I like to use a cheap solder iron and super glue to combine the parts.
Also a dremel and a small sanding machine.
Lots and lots of sanding paper primers fillers and so on.
At the moment i am working on a clone trooper amor!!
