Hello everybody and welcome to another video tutorial. Today we’ll be addressing the question that some of you had in the past as to how to change the nozzle on the CR10 V3 since the housing is very tight and difficult to disassemble. Well the good news is that you can do this pretty much as easily as any other machine if you know what to look out for in the process. As always, I am in no way responsible for any damages that may occur so do this at you’re own risk.
Before we even begin removing the existing nozzle we first need to clean out the hot end and there’s a very simply method that I prefer to use for this. The main method I use now days is commonly known as a “Cold pull”. Not only is this great for cleaning out your nozzle if it’s jamming, but it’s also great for clearing out the passageway when doing a nozzle change.
Although I do prefer to use some TPU while doing this, PLA will also work, but you’ll just have to be careful not to snap it in the process. To start things off, if you don’t have any filament already loading into your machine you’ll need to preheat the nozzle by going to “Prepare” + “Preheat PLA” and “Preheat PLA End”. Both PLA and TPU will both use the same temperature settings in this case. Now with TPU you have the option of tying the end into a knot which will make it easier to remove later on, so we’ll cut a piece off that’ll be long enough to feed through and feed it into the hot end. Just make sure that it’s a little longer so that it extrudes slightly. Remove the part that extruded from the hot end and begin cooling down the machine by going to “Prepare” + “Cooldown”. The hot end should be at its normal room temperature before continuing to the next step. Once it’s Cooldown completely you’ll restart the heating process while tugging on the filament at the same time. As the hot end heats up any residue will be dislodged when the filament is pulled out at a low temperature. As you can see I did this process with both TPU and PLA with the same results. Once again just make sure not to snap the filament while doing this step.
For the following steps here’s what I recommend you pick up for the nozzle change. While some of these are optional most are highly recommended. A ratchet with extender and bits, needle nose vice grips, magnetic tray, pipe joint tape and your replacement nozzle.
With the nozzle cleaned up we can now begin swapping the end so to do this will need some needle nose vice grips. Normally for most machines you don’t need this specific tool however because of how close the hot end assembly is to the components and the difficulty which can be experience in removing the outer shell I do highly recommend you pick this up. A small ratcheting socket set is also helpful however there are more specialized tools out there, so this one isn’t as necessary. You’ll want to take a close look underneath to check where the wiring is mainly located since the last thing we want to do is damage the thermistor or heater cartridge. To do this we’ll raise the hot end assembly up the Z axis by going through the menu system. Go to “Prepare” + “Move Axis” + “Move Z” and we’ll set the number high enough to easily access the hot end with our tools. As an extra precaution I would also recommend putting something on the glass bed just in case you drop a tool on the surface.
Anything after this point should be done with a minimum of one glove on your hand to keep from burning yourself. With your vice grips you’ll lock this onto the heater block while making sure to avoid any of the delicate wiring that’s on the inside. Luckily the design of the hot end assembly automatically places these components into an area where they’re less likely to get damaged. Here’s a picture of how this looks under my machine but double check just in case before clamping the vice grips in place. The nice thing about using a ratchet which has an extender on it is that the extender helps to defuse the heat far easier and prevents burning. So you’ll unscrew the nozzle carefully and remove it from the hot end assembly.
Before we begin putting on the replacement, we first want to add some pipe joint tape since this’ll help produce a greater seal within the threads and prevent material from oozing out. I personally prefer using the version which is thicker since it requires less wrapping, but that’ll depend on your preferences. This material can be found at any local hardware store or online depending on what’s more convenient. A very important note is to make sure that the hole isn’t in any way covered or that you get this material inside. This can cause some very bad nozzle jams so take care of this step. If it’s covered, simply use your tweezers to punch a small hole and roll the material around the edge of the thread. Now we simply screw back in the nozzle making sure to have it just tight enough to hold into place. Just as you’re getting close to finish tightening the hot end, you’ll hold onto the vice grips and tighten the hot end followed by slightly turning the vice grips to allow for a greater seal. DO NOT under any circumstances do not overtighten the nozzle since it can snap in the heater block. Simply remove the vice grips, and you’re ready to go.

Hello everybody and welcome to another video. In today’s review, we’ll be taking a closer look at the Ender 3 S1 by Creality and see what this machine has to offer. Full disclaimer, I purchased this machine with my own money in order to do this review, so everything you see here is based on my own opinion.
With this new machine, with have a newly upgraded build plate which is both flexible and has excellent print adhesion. While I have had this machine for a couple of months now, the build surface has held up and has not visible damage as yet. I haven’t had any issues with the prints sticking and removal has been quite easy with the print’s, self releasing if they’re allowed to fully cool down. In fact, I was so impressed by it that I order a second surface for my Ender 3 V2 which I had upgraded in a previous video.
This machine has been the first to come with ferrules connection out of the box, which I’m happy to report. What I have found confusing however is the fact this machine has proper connections while the CR10 Smart Pro still has tinned one. So although my machine has the proper connection types, I would still recommend you double-check yours since I purchased mine on Amazon and some reseller’s upgrade the machines prior to sending them out.
This machine does in fact have silent stepper drivers, however they did not upgrade the extruder fans to be more silent, so it can be still quite loud during operations. This is an unfortunate oversight since the hot end assembly has so many great innovations included within its design.
Similar to other recent machines, this one has a drawer which contains all the tools you’ll need to repair it in the future. This is appreciated since it makes it easier to keep everything organized and easy to find when you need it. I’ve gotten in the habit of storing original hardware, which I may have replaced, in this drawer just in case I need it later on.
The X gantry has a small clip to help to hold the cable to the hot end assembly, and while this allows for clean cable management, it doesn’t quite work correctly. When printing, the cable for the hot end assembly bends and cause the limit switch and motor connections to become strained. If you already have this machine, you may which to print this cable support to help keep this portion into place. You’ll need an extra long M3 screw to attach this into place, along with a Zip tie. I will have this file available on my website along with the PDF survival guide for this machine.
Thermal Runaway Detection was tested and is fully functional. The nice thing about this extruder drive is that it can easily be detached with the cable, so you have access to all the connections. This made it a lot easier to test as a result and will make maintenance in general a lot easier. The company has also recently released the source code files for the firmware, which should make it easier to upgrade in the future. Although not all of their machines are currently available, it’s likely that they may be in the future. I will include a link in the description below as to where you can find the repositories.
With the new dual Z axis, bed levelling should be less of an issue and shouldn’t be required as often. Both motors are linked together with a timing belt to help keep them in sync with each other. Although you shouldn’t have any issues out of the box, you’ll want to make sure that your stepper motor timing is properly synced up. For this, you’ll loosen one of the clutch screws for both motors and, with the machine turned on, use the menu to lift it up and down a bit. You’ll then simply re-tighten them, and should be good to go.
The spool holder and filament run out are both located on the top of the machine and have also been updated. The spool holder has the filament run out sensor attached to it’s front, which allows the sensor to rotate with the hot end assembly. While this helps reduce the amount of friction it does raise the overall height of the machine and because of my limited amount of space I had to create this filament guide to get around the issue. It should also be noted that having the spool holder on the top of the machine can cause more vibrations, which can affect final print quality. So although this is a great innovation, you may need to do some form of modification depending on your space limitations. I will have the STL for this modification available on my main website if you wanted to try it out for yourself.
With the upgraded hot end assembly, we now have the new sprite extruder, which uses a direct drive mechanic. It’s similar to that of the CR10 Smart Pro with one important difference. In this case, although it is does have a Sprite Extruder, it isn’t an all metal hot end. This machine has a Bowden tube which lines the inside of the heat break and should be replaced with a Capricorn one to prevent any future issues. At the time of this recording, some upgradable or replacement parts were not yet available within my area. The only way to get the upgradable components is by agreeing to the terms of service and become a Creality reseller. Due to how the wording of certain clauses are, I find this to be risky and have refused to do so.
So what is the final verdict on this machine? Well this machine is a very reliable one which has become my go to for many prints. With the source code released, it’s a great option for those just starting or more advanced user’s alike. The only sticking point at the moment is the lack of available replacement parts, so although that’s something they’ll need to address in the future, they have left it open to modifications and alternatives. So for me, this gets a solid 8/10 for both new users and veterans alike.
So how does Creality treat its vendors? Just how much do they want to control the message that goes out to the public? Well, I found this one their main website by accident when I needed a replacement part for a video. I personally find this to be very concerning and worry about how they treat their resellers.
The issue I found this with this is that they haven’t limited their use of any assets which are shared on their platform, and it could potentially be used to resell STL’s and take the revenue from any shared videos. At the time of recording this, this was the only way to get certain replacement parts from the company, since their resellers didn’t have them available at the time. So in order to purchase any items you must be signed up to this service in particular and be restricted to their reseller program. With some of their reseller’s limiting their selection of products this will make it difficult to buy replacement or upgradable parts which is most likely to limit the lifespan of newly released machines.
While I am focusing on the use of the information that’s shared within this contract, there are certain areas which could also be problematic. The clause of additional fees could easily be used to sell the work of other’s by including this as a service. Since this contract is clearly stated as being flexible and could change at any time, there is also the potential for this contract to be changed to something more questionable in the future.

Hello everybody and welcome to another video. In today’s review, we’ll be taking a closer look at the CR10 Smart PRO version by Creality and see what this machine has to offer. Full disclaimer, I purchased this machine with my own money in order to do this review, so everything you see here is based on my own opinion.
For those of you who follow this channel, you already know my opinion on the regular CR10 Smart and this was quite a different experience mixed is with some familiar ones. To start things off, I didn’t need to update the firmware in order to get the machine to function properly, which is always a good sign. If you need to update your machine, however, make sure to check out my other video since there’s quite a few things to be aware of when starting off. So while the update process is still quite finicky, it isn’t required to get a functioning machine.
Unlike previous machines, the company has decided to stop providing the source code and this will make future upgrades more difficult and can prevent newer features from becoming available. Like most budget friendly machines, most of these are notorious for not updating to the newer versions of marlin, which often limits their usability and can sometimes present safety issues. I did test thermal runaway protection, and I’m happy to report that the safeties are in place for the stock version of the firmware. One thing I would have liked to see, however, is a specific warning of was triggered to make it easier to troubleshoot later on. As is, there’s just a generic warning in place. Now, if this warning triggers’ when you first get your machine, I could be that you improperly installed the connection to the hot end assembly. So you’ll first want to reseed it, making sure that both ends are properly secured and held in place with both the clips and the bracket.
I’m happy to report that the automated bed levelling feature works quite well on this machine out of the box. With the inclusion of the adjustment knobs, is easily adjusted to ensure proper print adhesion. When you first get your machine, you’ll first want to manually adjust the bed levelling prior to doing an automatic one. Once completed, you can choose to include an auto bed levelling procedure in your G-Code commands or do so when needed. As long as your print bed is levelled, you should only need to do this periodically instead. I will have a separate video on how to level your print bed, but for now I do have the downloadable PDF for this machine if you need it right away.
This machine like so many others on the market has tinned wired connections which should replaced with ferrule one’s. This is unfortunately a pattern with most companies and I would like this to be changed in the future since it does pose a safety risk. I already have a video going over this process in more detail, so please feel free to check that out if you ensure what’s involved.
The hot end assembly has been updated to include the sprite extruder with the all metal upgrade. With this addition, you can now print with higher temperature materials right out of the box instead of having to add this feature yourself. There is still is a small Bowden tube connection that connects to the feeder, which I prefer to replace with a Capricorn one, but I wouldn’t say this is required unless you encounter issues. Both the entire Hot end is a custom design, so unfortunately it’ll be difficult to purchase replacements from any other vendors at this time, but it was designed so that key components can be easily swapped out. The remainder of the hot end assembly is quite difficult to take apart since all the components have been tightly integrated together. Luckily, it doesn’t seem like this should be needed unless you were doing any modification. They seem to have learned from the Ender 3 S1, and have added some additional support for the hot end assembly cable. The cable does still do a twisting motion when moving around, which could cause it to wear over time, and there isn’t currently a purchasable replacement cable. Some hot end connections use a non-standard connector, which could make alternative replacement parts more difficult to find. The heat break is also using a different length and threading size than what’s standard, which once again makes it difficult to find alternative versions of these parts. The machine which I purchased showed signs of pre-testing, so quality control may have improved in comparison to previous versions.
A great new feature is the integrated lighting which has been included with the machine out of the box and is something which I didn’t think I would even need until it was available. So far this has made it a lot easier to work on the machine and turns off automatically when the machine is powered off. Alternatively, you can turn off the light with the power switch as well, making this new feature quite convenient to use.
The bottom screws that attach the base of the machine are very easily striped, so be very careful when putting them in or taking them out. I will be replacing those since I don’t want to risk being unable to access the components of my machine. When you open up the machine, you’ll see the integrated Creality Wifi Box which I of course disconnected, so I could use the USB port to connect to my computer or raspberry pie directly. I have a previous video going through this process if you intend to do the same.
The build plate has been upgraded to a flex build plate, and they’ve added some indentations to make it easier to line it up during re-installation. I personally love this new feature because it makes it so much faster to swap the build plate in and out. If you have a printing farm, then having a series of build plates you swap out just became a lot faster with this machine.
This machine has a lot of new innovations, and I’m happy to see that they’ve been properly implemented. With this however we are looking at a much higher price point especially when comparing it to the regular CR 10 Smart. So is this worth the price? If you want something that works out of the box, then this gets a solid recommendation, but I would also consider how some of this has been locked down by the manufacturer. You see, without the source code files and easily purchasable components, this machine does have a limited life span in comparison to other machines. With a regular Ender 3 V2 for example, I can easily upgrade the hot end to whatever I feel like using and this means that I can replace par ts from a larger amount of suppliers, in turn increasing the lifespan of the machine. It’s for this reason that this machine gets a 7/10. It’s a good machine, but without additional support materials and the files it may not be as repairable in the future unless you’ve created an account with the company and signed this really shady contract. Ah, ya…. as a YouTuber, I’m not going to agree to that.
