In this video it take the existing filament sensor which has a habit of catching and replace it with a modified version which works a lot better. I go through the installation and design process of how this modification was made.
Hello everybody and welcome to the 3D printer Modding series. In today’s video we’ll take the notorious filament runout sensor that comes with the CR10 V3 and modify it to be more fluid in how it lets filament pass through it. I also have a follow up video which addresses a proper cable guide for the hot end so keep an eye our for that video in the future. As always, please do this mods at your own risk and I’m in no way responsible for any damages that may occur.
So as i mentioned in my previous review of the Creality CR10 V3, the sensor was very much holding back the potential for this machine. Because of the initial design for the filament intake, it caused a severe amount of friction to occur which in some instances prevented the proper flow of filament through the nozzle. Before trying to create a new housing i did run a test to see if I could simply replace the existing sensor with one that I had lying around however this produced an error which prevented the printing process from starting. Instead of modifying the firmware, I decided to change the housing which I believed to be the main cause of the issue. The electronics themselves were very well designed so doing this also make this modification easier for other’s to undertake.
So the very first step was to the remove the existing component and open it up to see what was inside. Luckily, this was fairly easy to accomplish because of how it was assembled on the machine. Once you remove the 4 screws holding it in place you are immediately greeted with the electronic components. To make my life easier, I did decide to remove the filament stand, however this is not a necessary step.
Once the electronics were visible I removed the two screws holding them in place so that I could get a better look at the housing that already existed on the machine. The first step was the remodel the area where the sensor would be sitting and once that portion as completed I was then able to focus on the entryway for the filament. The issue with the stock version is that the angles were too sharp and this was what was causing the large amount of friction. Also the alignment was slightly off and this caused the filament to get stuck in the switch portion of the mechanism. In order to address these issues, I created a gradual entry way for the filament the pass through and changed the point where the filament intersected with the switch. This produced a much more gradual entrance which reduced the friction significantly.
With this out of the way it was now time to create the connection points in which the two halves of the sensor would meet and combine to make the shell. I then added the bolt indents to further make this easier to assemble. So after a couple of prototypes I finally had the final version that I would be installing on my machine.
IF you decide to install this one your own machine you’ll need to do the following. You’ll need to add the two screws to hold the switch in place after which you’ll add the screws and bolts for the housing. In my case I only had longer screws available so I ended up only installing two of these across from each other. This also allowed me to place a much longer screw going in the opposite direction to attach this to the sensor mount. I added a bolt behind it just to make sure that it didn’t come off latter on. With that completed I installed it onto the machine and quickly tested it with both flexible and PLA filament. After doing my first print I can say that it’s still working quite well and I’m happy with the results. This was the resulting test cube which was printed with a 0.8 nozzle and scaled to 130%.
Although this may seem like a simple mod I found this to be one in which I appreciate the most since the friction being produced has caused my filament to break in mid print on certain occasions. Since the filament sensor is mounted away from the nozzle it doesn’t register a break in the filament and keeps on printing which has been a issue in the past. With modification in place it should prevent this from reoccurring in the future.
Ever wonder just how difficult it was to add automatic bed leveling to your CR10 V3? In this video I cover the in’s an out’s of this process and give you a final verdict on who this upgrade might be for. Make sure to check out the main review for this machine at this link CR10 V3 Final Verdict
Hello everybody and welcome to another review. So in today’s video, we’ll go over the BLT touch installation for the CR10-V3 and whether or not this is worth getting. Before we begin, I’d like to make it clear that this review was in no way sponcered and that I had purchased the BLT with my own money at the same time as the CR10-V3 and this represents my own opinion on what I’ve experienced.
In order to do this upgrade you’re going to need know a couple of things. Now in most cases when you first order your machine, it came with a usb stick which had everything that you needed to get started including the firmware upgrade that you’ll need. If you don’t have this however, that’s fine since it’s also readily available through the main website of Creality.com. The firmware comes pre-compiled which is nice however the zip file has some extra character’s which prevents the operating system from recognizing the files. So the first thing you’ll want to do is remove the extra character’s after the .zip. At this point you can then extract the files within the folder where you’ll be treated to the instructional PDF’s as well as the firmware.
Before flashing the firmware you’ll need to connect your computer to the 3D printer and the required cable doesn’t come with the machine so you’ll need to obtain one prior to installation. Furthermore, you’ll want to make sure that your chosen slicer software is closed was well as any other flashing software such as Xloader, arduino or pronterface. In order to do this upgrade, you will need to use the included Creality Sliser since simply inserting an SD card with the firmware will not work or using Cura and Xloader. This software is also available through the main website. While you might be able to use a custom bootloader, this wasn’t something that was tested at the time since the upgrade worked with the included software.
Once you have the Creality Slicer open, you’ll need to make the following changes. Go to File, Preferences and change the printer window type to “Pronterface UI” then select “Ok”. Then go to File, Machine Settings and change the Serial Port to “COM3” then the baudrate to 115200 at which point you can select “Ok”. Then go to Machine, install custom firmware and navigate to the blt touch firmware that you intend to install. In my case I renamed the file however you’s will most likely be called CR-10 V2TF188.8.131.52BLTouchV3.1.
Give the machine a little time to finish the upload at which point your ready to do the rest of the installation process.
To begin, we no longer require the Z axis Endstop so for this reason we’re going to remove this so that it doesn’t interfer. The next stage is the install the BLT touch itself. You’ll want to put the first two screws going upwards from the bottom of the sensor on the side which you see the 3 holes. Only the two holes will will have screws for them. Make sure to add the connector cable to the BLT since it will be difficult to access this once it’s installed fullly. After you can then install the remainder two screws to the appropriate location on the nossel housing. Remove the XE Transfer Interface Housing so that you have access to the female pin header and attach the connector to it. You can then reatach the housing to complete the assembly.
The next stage is to setup the BLT touch leveling and first we will do a basic bed leveling to determine the low and high points on the machine. To do this, go to Prepare, Bed leveling and allow the machine to complete the probing. We now need to set up the Z offset which is currently set higher to ensure that the bed isn’t damaged. Go to Prepare, Move Axis, Move Z, Move 10mm where you’ll set this to 00.00. Then go to Move 1mm and lower this the first couple of increments but not to far otherwise you’ll hit the bed. You’ll then want to move it 0.1mm at a time to get it to the appropriate height. Make sure to write down this value since you’ll need this latter. You can use a piece of of paper to help ensure that you have the proper distance if that’s what you’re currently used to using. Go back up the menue hierarchy and go to Control, initialize EEPROM where once you enter this menue you’ll get a warning beep. Go to the Motion, Z Offset and set the number that you wrote down here. Go back one menue and choose Store Settings at which point the machine will beep another warning. Navigate out to the main menu where you can then start your first test print. I’m using a model which was created by Bnimon on Thingiverse Since they created a file for the different nozzle widths and I had changed mine to a 0.8. I will be including the link in the discription below if you would like to use this yourself.
Make sure to keep the wire slack otherise the connector will get removed while printing. With all these steps completed it was now time to do a test print and these were the results. For any of you who’ve been doing 3D printing for a while now, you’ll have an appreaciation as to how long it can take to clean up a model such as this. In this case it took well over an hour just to remove the supports and I ended up getting large chucks half accross my room. So ya, I’d highly recommend some eye protection depending on the filament that you using and unless you have very calloused hands you may also want to use gloves. Over all however, the final model turned out pretty good considering it was printed with a 0.8 nozzle and 0.5 layer height.
So was this mod worth the effort. In my case I would say that it was since I rarely swap out my nozzle however if you swap out your nozzle more often then this may not be faster then simply hand leveling the bed although it is more accurate. So like most cases, it will depend on your use case but I would suggest adding this if you have the oppertunity since it is quite useful.
In this video I take the CR10 V3 and put it through it's paces to find out just how good this machine is. I talk about the build quality, some suggested improvements and the overall design and functionality of the machine. I also tested this machine with a some flexible filaments to see just how this machine might perform and show the final results.
This video is a follow up video to the original unboxing of the machine and you can view that video at the following link. Unboxing the CR10 V3
Hello everybody and welcome to another video. In today’s video I will taking a look at the New CR10 V3 printer which came out recently. This is the follow up video from the initial unboxing experience so if you’re curious about what it’s like to put the machine together, make sure to check out that video in the description bellow. Now full disclaimer before we begin. I purchased this machine with my own money and was not paid to do this video so everything you see here will be based on my own opinion.
To start things off this machine is a large printer which prints a dimension of 300x300x400mm and can reach hotbed temperatures of up to 100°C with a printer nozzle temperature of up to 250°C. Unlike many 3D printers this machine uses a direct extruder which pushes the filament directly into the nozzle instead of the traditional bowden tube. This feature makes is quite suitable for printing flexible filaments which is what was tested for this machine. Also included with the machine, is a run out filament censor which is located a the top of the machine along the spool holder.
If you getting this machine yourself, you’ll want to keep the spool holder height in mind since it does take up more room because of it’s current location. This is however useful if you’re more limited in your overall space since you can easily place this on a table which doesn’t have any fixtures above it. I personally did end up liking the fact that the control box was separate since this allowed me more options in placing the machine. I for instance placed the 3d printer sideways but oriented the box controls towards the front of the table so I would have easier access. Having the control box separate also makes repairs a good deal easier since you can completely disconnect the machine in order to do the proper maintenance without having to deal with the whole unite.
The hotbed itself has a very unique design in that it’s easily removable which makes replacements easier in the future and I do which more companies designed their print beds in a similar manner for this reason. This design also makes is possible to upgrade the print bed in the future with a flex plate which is great news for those who enjoy tinkering with their machines. The print bed is also pre-insulated to help retain the heating temperatures and is a welcome improvement to what can be typically seen in most printers today. I did see some reports about the V2 model having issues maintaining it’s heat however this isn’t something in which I found to be an issue with the model that I currently have.
While having a touchscreen is more visually appealing and less daunting to those who are new to 3D printing it is still fairly easy to navigate. The machine does come with some basic instructions which do help significantly in this area. There are some things you may wish to know since they can often be taken for granted. For instance, if you the filament sensor goes off because there’s no more filament available and goes into standby. In this case the nozzle will cool down which is a good thing for safety reasons however it will mean that you need to reheat the nozzle prior to changing the filament. This is something you can easily do by going to “Prepare + Preheat PLA + Pre Heat nozzle” This will only pre-heat the nozzle at which point you can remove the filament in question. Be very careful not to jostle the nozzle otherwise your print will shift and this could cause the layers to be more brittle when they come apart.
Now although the direct extruder is great for working with flexible filaments you definitely want to be aware that it can be difficult to maintain. The way it’s assembled, the wires do get pinched very tightly onto the side of the housing which does keep them out of the way however it can make reassembly interesting to deal with. Nozzle replacement shouldn’t be too affected however just keep in mind that you’ll want to raise up the print head before you do so. Creality has a very good tutorial on their YouTube channel which walks you through the steps and I recommend that you look at that video for more details. Most blockages can be removed with the aid of the provided tweezers so keep those nearby should you need them. For more severe blockages, you will most likely need to use the included needle to help push the blockage up and out but in most cases it can be removed by doing a cold pull. From a complete cool down state, start heating the nozzle up to temperature while pulling on the filament. This causes any deposits to be lifted up with the filament since they become just hot enough to stick to the filament being pulled out. This may have to be repeated 2 or 3 times but does a more thorough cleaning of the nozzle. One thing to keep in mind is that the extruder does have a bowden tube placed inside of the heat sink so on occasion this may need to be replaced however this should be a rare occasion.
The nozzle does ship with a 0.4 nozzle along with it’s replacement however I would suggest that you replace these with a 0.6 or 0.8 since this will reduce your print times significantly for larger prints. If you require more detailed pieces and are willing to wait significantly longer than it may still be worthwhile. When it comes time to removing the filament, You’ll want to push this portion forwards until the filament comes out. Make sure the nozzle is heated before you do this otherwise this will be far more difficult to achieve and could result in the filament snapping within.
The filament run out detector currently only accepts 1.75 filament which isn’t unsurprising since the filament trajectory could be problematic when the print head comes too close to it’s maximum height. I’ve had some issues with the filament snapping since it doesn’t have a bowden tube to help guide it’s trajectory. Fortunately this was mostly an issue with the cheaper filaments which were more brittle however part of this could of been caused by the extremely tight filament sensor. This filament sensor produces a lot of friction which may be the source of this issue and I would like to see this address in the future. When the filaments snaps, it doesn’t trigger the run out sensor because of it’s current location. This was far less pronounced when printing with TPU but was aggravated when using soft PLA. Having the sensor away from the print head is still very much appreciated since it make filament removal easier however I would like to see the angle of the spool revised along with the run out sensor. Having a gradual entryway to the filament sensor would get ride of the hard edges which seem to be causing the friction and should be a minor fix in the future.
The frame is very well supported and given it’s size I’ve experienced very little Z-Wobble which is very much appreciated. For the wiring, some areas have been glued to help ensure that their connection points don’t come lose over time which is a good call since I’ve definitely experienced this issue with other machines in the past. The only thing to keep in mind is that this will make it more difficult to replace such wires in the future because of how they are currently attached however if they last much longer then this shouldn’t be an issue. All the cables are clearly labeled so tracing connections are a lot easier and will make future modifications easier to achieve. Along with the sturdy frame, the machine has silent stepper drivers and a built in mosfet. Although I personally prefer when the mosfet is separated from the board because it’s easier to replace, I can appreciated the fact that there’s one less item to troubleshoot in the future.
So how did this machine perform? Well let’s start with the default Test print that comes which the machine. These prints are always a good way to make sure that you’re machine is functioning correctly and should always be the first thing that’s printed. So in my case I choose the dog and although it’s difficult to see just how well it printed because of the filament color that came with the machine it did very good. I then tried printing with flexible PLA which I soon discovered had a tendency to get stuck because it shaved so easily within the gear system. The results however were very comparable to the dog print. With that out of the way, I immediately changed to a 0.8 nozzle to see just how well it could print with a wide variety of materials. Once again I printed with the flexible PLA as well as some regular PLA and TPU filament. Here were results of the standard Benchie Test. I then followed up this print with a large scale print for my client in TPU which for NDA reason I can’t show on video. I can say that the 4 day print was very comparable in quality to my small Benchie Test print in TPU. I also 3d Printed a bust of one my sculptures. To test the full build volume, I then printed a vase in vase mode.
This machine is really good. Especially if you already know that you want to use it for flexible filaments. While the user interface is perhaps not as modern, it does the job quite fine and with a couple of tweaks this could be an even greater machine. So would I recommend this machine? It’s a good machine if you already have some basic experience. I probably wouldn’t recommend it as your first printer because of the user interface and most user’s don’t require such a large build volume starting off. This is a very good upgrade to your current repository and is an affordable next step.
