Help to choose the 1st 3D printer - Tronxy X5SA Pro or Creality CR-10 V2

[curious aardvark]

I found that Creality has better quality both on the parts they use,
as also that of construction solutions.

Yes you missed something.
You ignored the reasons I gave for why creality suck.

Weird as you claim to be an engineer :-)

Also creality have one of the worst reputations for build quality and customer support in the industry. They make I3's that have been crippled compared to the original design.
There is no logical reason - josef prusa's design is opensource, you don't get sued for copying it.

As far as moving a large mass around - you just need better belts, linear rails and more powerful stepper motors.
I admit I have bolted my printer to a fairly substantial aluminium sheet with rubber feet (frame was in 2 parts, so i made it one :-). So that probably helps somewhat with my particular machine
Also the acceleration settings will also help.

But basically a good i3 can and should be a very fast machine.


And until you've attempted to align dual side by side heads - you have no idea how tricky it can be :-)

Look into the mosaic palette 2.

Most reviews on youtube are done by people who are paid to review the machine.
Mostly they are 'paid' with the machine itself.
And that's one reason there are so many positive creality reviews - people don't want to kill the golden egg laying goose.

Even a 'bad' review will say things like: 'well it's got a few niggles, but on the whole its a decent machine.'
After all, who wants to upset someone who gives you free stuff ?

My other reasons are simpler still. Creallity leads the pack in the number of issues and problems people come here with.
We have significantly more posts about problems from creality owners than ALL other 3d printer manufacturers put together.

I mean, by all means ignore everything I say. My opinions are purely based on extensive experience with 5 assorted 3d printers and 6 years of dealing with issues on this forum as well as extensive study and research into 3d printing in general.
I just cannot be arsed to set up a youtube channel. I'd be up to my arse in free printers if I had, as it's the only question manufacturers ask when they contact you.
And I have been contacted a fair few times.
