Wouldn't need to rotate it at 150x150 with CR10S. But it would take days to print at 400 high with any decent quality. Think if I was building tall parts I'd fit it inside a box to retain the heat and probably upgrade the bed. But that said I've not done a thing to my printer other than print adjusting knobs for the bed to make it easier to setup and I'm very happy with it for what I do, which isn't anything fancy or taxing.

I can vouch for that,. I've printed lots of parts for testing on machines and I've also got a couple of customer machines running 3D printed PLA motor mounts in a 10hr day working environment. All the machines I build have at least 3-5 individual 3D printed parts ie: Limit brackets etc and growing as they test out ok.
Re: Reliable printer out of the box ?
I see the Cr10s has one variant which is 500x500x500 build area. Good size but wow is that expensive (for me anyhow)

IIRC I paid about £190 for the printer via Creality's AliExpress store, including the glass bed option, as it was on special offer at the time.
I’m a bit confused about this. I buy Chinese parts all the time. But wouldn’t a printer coming from China be a clone of the real thing ? And therefore worse quality ? Or is it a Chinese brand ?

The Dual gear filament head looks exactly the same as what's on my 10S but they have integrated the out-or-filament switch into the head by looks of it. Again this nothing special.
The extruder looks pretty much the same but they have a switch type bed leveling sensor fastened to it. Again nothing special and could easily be added for a few Euro's.
The main thing I see between the V1 and V2 is the base now houses the electronics which I wouldn't want if I'm honest. The heat of the bed and printing cannot be good long term for those electronics. Large prints take days and all the heat from printing will radiate down into that box. I much prefer my separate box.
I wouldn't pay $200 more for the V2 I'd buy the 10S and upgrade it with the $200 saved, then you'll have a really great machine.

Creality is a Chinese company. The official website is www.creality3dofficial.com
They've done a brilliant job of refining their printers to make them as cheap as possible, while still being reliable, so they filled the gap between the absolute budget build/print your own using hundreds of bits then spend hours fettling it to get it to print consistently, and the more expensive turnkey solutions.
Re: Reliable printer out of the box ?
i use emachineshop (free) cad software and Cambam (licenced) for my CNC projects.
Whats a good combination for 3d printers please ?. Ive never had any exp with them

You want a 3D modeling software that can save in STL format. Then use a Slicer like Cura to create the G-code. I think fusion 360 now also a slicer integrated into it.
Re: Reliable printer out of the box ?
If you want a reliable printer and your money to go into the right direction buy Prusa or Steel, as they have better quality electronics.
Hi guys, a bit late in the discussion.
If you don't want to spend money, buy it assembled second hand, as many of the freaks will like to buy the latest edition and could be selling one in classifieds. And search Facebook for the Prusa group and ask there.
Under 1k there are not other better or reliable printers. All else has a serious fault or 2. Not that the prusa is perfect, as it would have benefited from hiwin12 and would have become perfect.
When i say reliable printer i mean to work 24h without any fault and produce impeccable parts, properly sized parts that fit together, and most of all does not burn your house.
In a printer there are like 100 things to adjust in the program for one to understand properly what's going on. It took me about a month to become an expert, playing 10h per day with the thing. Once you understand the logic behind everything its very easy to correct deviations. The Prusa printer helped in that as was super reliable.
Now add to that a crappy printer, with crappy electronics and god forbid crappy extruder and you will never understand whats going on and it will finish in a corner somewhere.
Just my 2 cents.
PS. I print and sell a cnc dust shoe / see signature/, it takes like 24h to print the main part and it has to have a tight fit to any spindle. Its a very tricky print as one has to take into account also the retraction of the material after print, that is opposite for the 2 holes, one tries to become bigger and the other smaller due to the material cooling and stressing the print. Also have printed my self working Japanese flute, working chuck, and many more things, usable things. Also have repaired my friends crappy printer so i know the difference
What i am saying is the main thing is to learn the printing and concentrate on designing and producing, not figuring what is not right and repairing. Filament is cheap, but a 24h print is 20e in materials. A couple of fails and you are in the hundreds of lost money

You probably should understand the tool-chain.
CAD: You have your CAD software - which you're familiar with from your CNC work. That's pretty much your choice.
TESSALATION: Now, the 3D modelling/printing process then leads you to tessellation - the transformation of the CAD output into a description modelled into 3D space in terms of generating a (lot of) triangular faces that describe the object. Imagine the wireframe image of a 3D-object, that's kinda what I'm struggling to describe. That is the STL format that Jazz eludes to. If your CAD will generate STL then stick with that. F360 (that I'm familiar with) will export objects as STLs. https://www.emachineshop.com/help-im...ort/#undefined suggests the emachineshop's CAD software will also do this. You probably want to use CAD software that exports the STL directly rather than using a 3rd-party agent.
SLICER: Next, you feed the STL object into the slicer. The purpose of the slicer software is broadly similar to CAM - it generates a series of layers, maybe 0.25m in height each (user programmable) and generates the X/Y tool path for the 3D printer, often presented as G-Code. Each layer is essentially a horizontal slice through the STL model at that given height (hence the name). There's lots of slicers on the market, usually bundled with the machine (and maybe optimised for the machine). It's within the slicer that you'll control filament parameters (extrusion rate, retractions), extruders (temperatures, cooling fans), machine (feed rates), to output a file suited to print.
PRINTING: Maybe integrated into the slicer, or a separate printer control program, or you simply dump the output from the slicer straight onto the printer (removable media) and print from the printer.
My particular toolchain:
Fusion 360 for CAD and tessellation. The STL Export integrates with the "QIDI Print" application that provides the slicing and is a poor-man's version of the very popular Cura software. From there I can export over WiFi to the printer and elect to print from that software. So, in a nut-shell, F360 and Qidi-Print.
But your choice will be very dependent on your CAD intent and your choice of printer.
