Anyone tried the Creality CR-10 3D printer?

@neverdie What kind of print speeds are you going for. The quality at higher speeds I think depends largely on the rigidity of the frame of the printer. Somehting like mine which is considered an I3 clone which is an open frame printer vs something like you mentioned, a hypercube is going to be different.
@dbemowsk I'm just trying (and apparently failing) to understand why someone would want to own a hypercube instead of an i3. OK, so the frame on a hypercube is more rigid. So....what? Does it do better prints? Does it do the same prints faster? i.e. why do I care? Even if the i3's frame isn't as rigid, maybe it's already rigid enough that being more rigid has no discernable advantage.

Anyhow, partly for family reasons, I think I'm probably going to order the Prusa I3 MK3, even though production is backlogged with orders. 1. It seems more kid friendly than what else I've seen, and 2. its very low noise means I can run it at night without waking anyone up. My wife did not at all like the noise my CNC makes even during the day, so that's partly why it was banished to the garage. Maybe we can run the Prusa inside the house, provided there exist print filaments that are non-toxic when used for 3D printing (I haven't yet looked into that, but maybe PETG is one such filament).
The other, new reason, now is that maybe I can leverage Tom's research on filament properties. I hope I can be fairly confident of getting the same results as him, provided I use the same print profiles as what worked best for him on a particular filament. Since he's using an MK2 to develop his data, the results should translate very nicely. I'm hoping this could save me a lot of testing and trial-and-error.

@neverdie I didn't realize that was your reasoning behind the questions. One nice thing about owning a 3d printer like the I3 is that even though it may not be quite as rigid, you can print parts to make it more rigid. I saw this meme on the Anet group that I am on on Facebook: You buy a 3D printer to print a 3D printer and then return the one you bought.
There was the talk of printing in ABS and PETG. Using the I3, you should be able to print ABS if you build an enclosure. As for PETG. that you should be able to print fine straight out of the box.

LOL. Very funny!
And from what I've seen in reviews, the corollary to that would be: buy a 3D printer that, even if it's bad, is at least good enough to print the parts needed to eventually make itself print well.
Looked at that way, 3D printers are a marriage made in heaven as the remedy for sub-par Chinese quality. :grin:

@NeverDie maybe because i3 design is common, for people watching.. I can see a big kossel behind him ;)
regarding print strength, another vid if you're interested, it's about volcano hotend.
at 8:10
https://www.youtube.com/watch?v=93LJui-pC2Qstrength should not be influenced so much by the printer I think, except its calibration, important. Strength can be improved with the right filament, hotend+nozzle size+settings, and the way the object is printed (for exemple if force would be applied in same direction as printed layers then it could delaminate).
Cool, curious to see whether you'll buy one, and which one :nerd_face: I feel you have a preference for prusa :)
It would be cool to have a printer that had both a regular hotend (for finely detailed print jobs) and a volcano hotend installed on it. Maybe then changing from one to the other might be as easy as changing which one gets get fed the filament.

@neverdie I use XT60 and JST connectors on my hotends, 2 minutes job to replace, including heating and removing filament.
You seem to get the strong points of a cube design, speed, sturdiness and "enclosability".
The kinematics can be corexy or simple cartesian (flsun cube) or even wicked gantrys like the ultimaker.
As long as you are near the 30-35mm^3(cubic)/sec melting limit of the Volcano heatblock you are maxed out and can't go any faster in speed. Knowing that usual layer height is nozzle diameter/2 and layer width is 1.2nozzle diameter, divide the more realistic 30mm^3/sec to the widthheight and see the max speed you can achieve. That should determine the type of printer you use. Also remember the max speed is achieved only at long straight moves, acceleration plays a huge role, and accelerating a big heated bed with glass on top is not easy, while throwing around a light bowden hotend on a corexy is a breeze. Like comparing a narrow, curvy, mountain road for a big truck vs a sports car.
The noise is dependent on the drivers, use tmc2100 or later (2108, 2130, etc) and all noise is gone. What control board to use is a whole new story. -

Funny you should mention that. At the school district where I work we have some Makerbot 3D printers. These use the Makerbot Smart Extruders. I can literally change the extruder in less than 10 seconds. I don't know if they have different types of extruders, but that would be nice.
The back is magnetic (the four rounded tabs) with a spring loaded header and a locking shaft for the extruder motor (left of the pin header). Once your filament is unloaded, you literally pull the extruder off, and snap the new one on. If they had different extruder assemblies, it would be an easy change. Problem is, one extruder assembly costs just over $200 US. -

Based on those assumptions, I calculate 41.7mm/sec as the max speed.

Well, that does make sense. So, if a corexy has a faster print speed, I guess it will be coming from that. So, what kind of print speed improvement (as compared to an i3 design) does that typically translate into? By that I mean, is it typically, say, a 10% improvement, or is it as much as a 400% improvement?

@neverdie that depends entirely on the part you print, big simple square piece, no cutouts equals less difference. Complicate parts, lots of direction changes, equals more time savings. Remember every printer will print slower than what the slicer estimates, slicers don't take acceleration time into account usually, or they use a very conservative value.

there are so much settings, and "little" things to know that's not easy to explain everything :)
Volcano is simply an extended e3dv6, maybe 1cm taller. You could just buy the volcano heatblock and nozzles and update an e3d. I have a lot of spares parts for hotends, handy.
It has a bigger heatblock=you can push more filament in it, and if you don't need a 0.2mm and very fine details, that can save a lot of time, like divide by 2 print timeAbout printers, well, I already exposed my points. When i started, I hesitated to build an i3 Steel (i wanted something sturdy, I prefer sturdy/fast/precise CNC's machines, makes sense to me for a good start). Remember the first commercial slow color ink printers 20-25 years ago??
So I was going back&forth, read a lot, asked for advices to a few gurus on reprap forums, and finally I thank them and am happy with my choice. But this a choice by a "maker" (not "afraid" to build/study new things) + I like good stuff.. and it cost me less than an original prusa! approx 350, 2years ago.imho, what I "don't like" in the hypercube is:
- rods and LMUU : I prefer vwheels like on the dbot printer (cheap vwheel on ali). With the slots acting as linear guides and replacing rods, it gets more sturdy
- the X axis with its vertical rods which is the same on prusa though.. not the best if you have weight on your gantry. Here, I use bowden setup, so it's lighter&faster to move. but I'm not fan of this vertical rods strategy especially for direct drive. that can work, but can be limiting too at a moment.

Are you using a thermocouple rather than the thermistor on your hotend? Since the E3D V6 has the capability of reaching thermistor destroying temperatures, I don't understand why a thermocouple isn't the default. I guess because it's not as accurate or something? If so, how is the lower accuracy of the thermocouple managed? -

I don't care about accuracy, I print a temptower and decide the best value for a filament lot that I buy and a nozzle/heatblock I intend to use. A full metal heatbreak is all you need, a teflon lined heatbreak tops at 240-260°C, the thermistor can go up to 300°C, ABS needs 240°C at most, PETG 220°C, PLA 200°C. -

I typically print my ABS and PETG at around 240°c and have never had any issues with the thermister. Boards that run skynet or marlin as their firmware should have thermal runaway enabled.

This is my corexy workhorse, all metal, linear guides, has a few hundred hours of running without any trouble, only improvement I did was adding a piezo sensor for bed leveling.

@executivul did you buy a kit?
@gohan It seems the link @executivul provided is the kit. I wouldn't know how to order it, though, as I can't read Chinese.
The price is certainly cheap though. Is it simply called a TaoBao 3D printer? Is there some other source for it?
You know, it already has 2 stepper motors for the z-axis. If you could just add a third, then maybe true auto-leveling (i.e. not just in software) would be a snap, since 3 points determine a plane. Well, you get the idea. In practical terms it might be easier to have one at each corner of the bed (for a total of four). The extra oomph might also help with accelerating the bed, since that's the weak leak in all of this....

Guys the printer is a kit. I used the Android taobao app and contacted the seller, he was nice enough to arrange shipping via a Shenzehn shipping company and DHL, paymend via paypal, the guy is reliable.
I've bought the mechanical kit only since I already had all the seppers and electronics from a Prusa i3 clone.
For me this was the best printer I could buy in August 2017 for that kind of money, far better than anything on aliexpress or ebay back then and even now. He was talking about adding it to ebay, but I don't know if he did it by now. -

@neverdie you can't! since any missalignment will cause binding on the z movement, the linear bearings and ball screws are pretty sensitive to missalignments
