@@martindare5803I print a lot of PETG with bed temp at 70°C, and the CR-touch works very well at least for me in that temperature environment. So I'm very happy that I got it.
I was having similar results and found I had misconfigured klipper so that the input pin wasn't pull down. I am not sure how Marlin handles it, but this could have been the issue.
What a great and thorough review! I hope my infant daughter grows up to be like you! You have quickly become a trusted source for information for me on 3D printing and CNC, and I always look forward to your videos! Thank you to you and your brother for the great content!
I would try a different CR Touch. I have one and it works great. I have seen similar tests by other trusty creators and they show a very different result. They showed the CR Touch ahead with far better scores. I think you just got a defective one. Not uncommon with any electronics.
The CR touch may very well be a licensed copy, it actually looks like an improvement over the original and has been re-designed to work plug and play with the Ender series printers. bTW, I've seen other reviews of this where it actually worked BETTER than the BL touch, so you might want to get another one and try it again. Your's could be defective. The PINDA inductive sensor looks like an improvement over the commonly available larger units, however there is nothing wrong with those when used with spring steel coated build surfaces. Note that inductive sensors are available in both NO and NC PNP or NPN type switches. The NPN type can be run at 12 or 24 volt power with 5v logic switching while the PNP type are restricted to switch their output signal at the power supply voltage. Since these sensors perform best above 6v power, the NPN type is preferred. These switches are Open Collector. PNP switches will require a logic voltage level conversion. NO and NC sensors are both OK, but you will need to configure the software to use the kind you have.
Great video and pretty much the only one that compared all the popular probe types. One thing I'd mention though, by testing on different printers, it adds a ton of variables. Mainly that the accuracy of the Z axis greatly affects the accuracy of the probe. I'd love to see a video where all the probes are tested on the same printer, but using different mounts ofc.
You and your brother are doing some of the best tech videos ever. To the point. Showing exactly the information needed. Very impressive. Please keep up your great work!!
I just hit play on this video. Her videos are always so great. I'm so glad it's not a review video. Please keep making videos like this and make videos setting up your favorite things
Yea, I wanted to say thank you too, your videos are great, I just got an MK3S+ and I watched your whole assembly video before building, big help. My latest issue is my prints keep turning to spaghetti at mid Z heights (seems to be around the same height). People say increase temp, but it's PLA at 215 C, so not sure how much higher I should go.
Hi, it would be easier for me to find the cause if you can make a video. But I would say if it’s a temperature issue, it shouldn’t fail at the same height every time. It should fail or you should see the problem once you start printing the first few layers.
If it occurred on same height could be a couple things. Does it happen on all models? You can test this by printing a tower taller than where it starts to mess up. If it's on a single model it's possible the model has a design error or slicing error
Excellent testing, professionnel et approche scientifique, un nombre suffisant d’objet à tester pour être crédible ! Tu as tout d’un laboratoire dans ta façon de faire, continue, c’est génial ce que tu fais ! Même si je ne parle pas très bien l’anglais, tu es ce qui manque à tous ceux qui parlent d’imprimante 3D. Bravo à toi et continue, tu es géniale !
I look forward to your videos. Another great one. You and your brother are on to something here regarding 3d printing tech. I'm not sure what yet but I can't wait to see it.
with a theme like this, I normally doze off after 2 minutes...but funny enough I was awake during the whole video. Again, Prusa shows us that quality in every detail leads to outstanding results. Your worst candidate was off by 10%. But 10% of 0.2mm is just 0.02mm. My bed screw has a pitch of 0.75mm per turn so to achieve the accuracy of your worst contender by hand I have to be accurate within... roughly 1/40 of a turn. You make me do difficult calculations, oh my god. But here is a challenge: The Strain Gauge is not very accurate as it does only one move to measure (I claim). Can you write G-code to make it move once till contact, then back off 0.1mm, and then measure again with just 10% of the speed? I think it would be crowned the KING. Thank you for this FAN-TAS-TIC video.
I have a CR Touch on an Ender 3 V2 and one on a CR-10s. I do notice that the pin retraction is slow and the speed does vary but it doesn't seem to affect accuracy. I've done several tests on both and the worst I ever got was 0.007 and the best at 0.002. I think all are good enough that it won't show in the print so it seems like whatever is cheapest is the best option. I'll probably try a 3D Touch on the next one.
Ok, I ran the experiment on the TH3D EZABL, an inductive sensor similar to the Prusa Pinda, on my Ender 3 V2. The probe points were 3x3 by default; I'll re-run when I update my firmware and set to 4×4. On 3x3 I got average standard deviation of 0.0031, or 1.56% at .02mm layer height. 👍
Nice data. One thing I would be interested to see is temperature compensation. I know that super pinda and bltouch both have a temperature sensor and they do compensation on when the probe is warmer or colder, but do the others have similar features and how much are they affected by ambient temperature
I installed the CR-touch on my good old Ender-3, and I'm quite happy with it so far. I really just bought it because it looked sturdier and a bit nicer than the BL-touch, but it also works very well for me, and an inductive probe was no option for me unfortunately, because I like to use a glass bed from time to time. Thank you for the comparison 👍
I’m not surprised by the CR touch, I have one myself and it does alright but you bring up a great point on the inconsistency. I think I’ll switch to the BL touch, though I’m not crazy about its appearance. It’s also funny that creality firmware doesn’t seem to work with their own product. Given this along the fact the CR touch literally comes with the instructions to use the BL touch firmware. I smell a company that has an insufficient firmware development team.
I believe you received a defective CR Touch. The reviews I'm watching show a slightly better performance than the BLTouch. Anyway, your thorough analysis and method is really good. Props on that!
I really enjoy your videos. You deliver the content clearly and calmly. I hope you do not neglect your school work, this is more important than teaching your viewers. I am sure your parents keep that in mind. Children don't develop your level of confidence and intelligence without good parents as mentors. Well done to your and your parents. I look forward to your next video.
I agree. But do not worry about her school work, I know about Asian moms. It is not just the presentation that fascinates me, it is also to a big part the preparation and research. I also look forward to the next video, a very impressive channel.
@@aps3000miki Agreed, my daughter is smart, hard working and is on track to get a 1st in an honours degree, she could if she wanted, go all the way to a PHD. But if I think back to when my daughter was that age. I just can not imagine her presenting so professionally. Without wishing ill will I hope this young lady does not get scooped up by Disney, the world does not need another Brittney. Part of the reason I watch is because she reminds me of my daughter. Apart from when she was a baby. We always treated her as a young person, and encouraged her to take decisions and responsibility. We are far from perfect roll models but she's become the best of both of us. I think we underestimate the ability of young minds, there is much we can learn if we listen.
CR Touch was bound to be dodgy it was Creality made! I would like to know which has the greatest tolerance range, my Ender 5 Plus's aluminium bed was high in the middle like the majority of those machines, because of this the bulldog clips deformed the glass from the corners and took the bed out of the BL Touch's tolerance range. I fixed this by using the screw type bed clips that can be fitted so they just hold the bed without being too tight, I placed just two of them in the centre left and right as there is no bed slinging and just Z motion and this is adequate.
Your CR-Touch seems to behave a bit different from mine. When probing, the Z-axis start to lower, and CR-Touch pin touch the bed, and it will only go low enough that the pin will dip about 1/8in (1mm), and the LED colour will change and Z-axis start to rise. So my CR-Touch doesn't need to go low enough to trigger the pin to "retract" all the way in. So possible you have a defect CR-touch.
I have a CR 10S Pro V1 which came with an conductive sensor i had a terrible time leveling, so I switched to an Inductive sensor. Based on recommendation from Make Muse. It has worked good then i switched to a glass bed and had to adjust so close to the glass it was a problem if a part warped. So then I went to a composite bed plate and glue stick. Recalibrated, releveled the table, the machine frame and tightened the bed springs. Now i get very accurate level. I want to repeat your study to see how accurate and repeatable it is. Can I beg for the excel Template?? You guys are so good. I share your video with friends. Although you talk too fast for my old ears I just replay that section and I can get it. I am learning from you guys every video. the oven knob and Fan blade was great. I also use Fusion 360 and OctoPrint on my 1os Pro V1. I did add struts too you may want to see what I did it stiffened the Z by a LOT. 10X or more stiff. Take Care you guys, tell Mom & Dad Hello, You have great Genes. D
It looked like you only tested the cr-touch on a magnetic build plate. Might try testing it on a glass build plate, the magnet might be influencing it a bit.
My results are better than the bl touch results she comes up with. CR touch on glass bed. Ran 5 cycles to achieve a sum average then repeated the whole process 5 times. My CR touch on a glass bed after 25 cycles comes to a 1.18% average.
@@chrisramey5033 Your not the first person I have heard make the claim that the cr-touch is more accurate than the bl-touch. This is why I think the magnetic bed she used may be influencing the results. I am happy with the $11 3d touch kits I have been buying off Aliexpress and will continue to purchase what is cheapest, so it dosnt really matter to me which one is more accurate. I would like to see the test repeated though with two different printers that are identical in all ways except for the bed, mostly just out of curiosity.
I actually had to take my CR touch apart this week and fix it because the metal probe was slightly bent and was getting stuck in the sensor causing a blinking red light and no function. Really disappointed with it especially after seeing the results of this video. I feel like they could make it really accurate with some more thought put into it
Thank you for the stright forward explanations and the added Excel tips! I have an old MakerFarm Pegasus 12 I"m upgrading to add mesh bed leveling with the BL Touch. I wished this video was available a year ago. I would have purchased the cheaper 3D Touch knockoff. :)
On v-core 3 i had problems with 3d touch, because bed leveling have 0.02mm tolerance. My 3d touch had deviation around 0.021, after turning screw i got deviation around 0.005 and i was able level the bed, but i also ordered original bltouch, just for sure and consistent deviation.
There is a Marlin command M48 to test the probe's repeatability, the methodology it uses should give the right result because the testing method in this video has many factors to affect the final result.
@@AuroraTech I’m one of your subscribers and I looked at all your videos, but I couldn’t find any on the Autolev brand bought from Substanica 3D. I’m a older gentlemen and not the best at the computer. Each time I watch the TH-cam videos they are older and the screens have changed so it is confusing. I’ve watched your videos and you explain thing very well and have had some success with your instructions. I need assistance to get this probe working on my Ender 3. I’m terrible at downloading and getting into my machine. I would appreciate any assistance available in helping me or a place I can get the assistance I need. Thank You keep up the good work
This is not one of the major leveling sensors, but I saw they also have instruction videos on their site: Hardware Installation: th-cam.com/video/DjAO5SMCNNk/w-d-xo.html Firmware update: th-cam.com/video/rsSK1m6XlbI/w-d-xo.html www.substancia3d.com/AutoLev/
I’d like to see all of these tested using the same firmware. I’m using klipper and I have the crtouch not retract the pin while probing. It seems like it would be more consistent that way.
Hi! Thanks for your video. I was wondering if you can give me some directions with my cr-10 max. It's been an awful experience. I don't know if the fact that the printer comes with such a big bed, it's part of the incovinient.
you can paste the data in excel and use "text to colums" from the data tab; select space as a delimiter, apply and delete unnecessary cells. that way you dont have to do all of the time consuming stuff manually
Great video. Ideally, testing would be performed on the same machine and build surface. I've had mixed success with the 3dtouch - unfortunately there are multiple versions being sold. The older '2.0' version was problematic - poor precision due to play in the play in the probe, and inability to 'stow between samples' (in Klipper). The newer '3.2' version seems to have fixed these issues, and I now get comparable performance to a genuine BLTouch on an Ender3V2 for a fraction of the price. I don't know which version you've used in this testing - your mileage may vary. I haven't tried inductive probes or strain gauges. 👍 Good stuff!
Lets be honest here though, its barely a difference lmfao. I have a cheap ahh ender 3 with a cheap ahh 3d touch. Its impossible to tell the difference between that and a bamboo labs. The motors along with the electronics along with the firmware, are all the same. With the only difference being the frame and random features.
I can't believe, how Průša called his sensor! :-D. I can't tell you what it means (in his language), since there are kids involved in this channel... He has a lot oof sense of humor, making this word say half a world :-)
Great job, the CR touch retraction is controlled by the CR touch after triggering, the retraction speed should not affect accuracy, but different amount of probing points and different printers and control boards will. Better not use 4x4 probing
My CR-10 Smart Pro when auto leveling the CR Touch drops twice for each point, once it moves quickly and the second time moves much slower. I noticed that in your video it drop only once per point. I wonder if this has anything to do with the poor result.
First time viewer here, I was taken aback by his young the host is. Damn, young generations are getting smarter by the day; is this what it feels like to be middle aged? Despite me only in my 20s
You saved few $! Thanks a lot. I have a BL touch knockoff and although it works well I never liked the plastic needle. I am always concerning that the tip will eventually melt at a certain point during probing.
I have a quick question, I still have either the old 8/16bit Silence MB for each of my Ender 3s. Will the BL touch will for it? Also THANK YOU for this guide! Straight to the point, Data to back it up and variations to results considered! Couldn't ask for a better guide!
Thanks. I had the creality one in my cart. Desperately trying to fix a warping issue but already threw a lot of money at it so trying not to order this unless the other parts don't help. At least if it comes to that I know which one will be accurate!
I'm about 90% certain it's not me, but I've had 2 bltouch and 3 3dtouch units fail on me shortly after installation...I mean VERY shortly! The longest one was a 3dtouch that lasted about 2 ½ days. I tried them on 2 different printers, so it can't be the printer's fault, right?
I have around 10 printers, using different ABL sensors, including both bltouch and 3d touch. They both worked fine for years, with no issues at all. No offense, but... besides the printers, sensors, there is another very important variable...
@@georgecarter5664 maybe you can give me an idea why then? They all behaved the same way: worked initially, then started the fast blinking thing and stopped accepting commands even after power cycling the printers. Two of them then quit entirely after that, not even lighting up. No one I've spoken to can figure out why, and I can't find anything online that explains it either. Thanks! 🙂
I tried one of those 3D Touch clones and couldn't get reliable results from it. I suspect that there is a little bit of luck involved in getting a good one.
In Canada the crtouch can be had for a third of the price of bl. I think the prusa should be excluded from this because the barrier to entry for most people to buy a prusa is 3 to 4 times the price of printers with similar print quality. I knock prusa alot but if you live in Canada then you'd understand. Plus they haven't evolved at all because they have such market dominance that they don't have to. It's holding the whole consumer level printer market technology back by years because everyone plays flow the leader. Ask yourself this question, when will people without any technical know how be able to buy a printer and plug it in then be able to open a file and press print like you can with an ms word document?
i'd love a strain gauge made by prusa, seems like they are on top of the ABL game right now. but i just low how you can't even tell there is ABL on the strain gauge by CR
I have a Creality 4.2.7 board and using a CR Touch. Works fine but starts to slow blink after it starts printing. Is that normal or is there a way to make it stop? (Update) I tried a different CRTouch. That was a loss of money it did not make any difference.
I got it fixed by turning the internal pull up resistors on my board.4.2.7 and 4.2.4 Creality Motherboard. PB0 and PB1. By adding this to my pins_CREALITY4.h at the end of the file #define BOARD_INIT() SET_INPUT_PULLUP(PB0) SET_INPUT_PULLUP(PB1) Thanks to Scott Lahteine
i have an cr-touch on my ender3(4.2.2) and don´t find it much slower than my previous bl-touch (the retraction speed of the sensor has no influence on the measurement result, since it only depends on the triggering time when the sensor starts to move, how long it then takes to fully retract is irrelevant ) with the m48-command i get 0.001250 on the cr-touch, while the bl-touch was around 0.004500 i´m not sure if the m48 is as accurate as your measuring method greetings from germany
CR Touch pin shakes like crazy! When printing. You're readings of the CR touch are totally correct. 👏 You are doing awesome content subbed and will follow your new videos.
I really enjoy your channel. You present the printers and other devices with clarity. Much better then most of the 3d printer reviewers on here. You are amazing at such an age ( I'm only guessing you are younger only because in one video you mentioned your mother would be upset by using her microwave as a kiln-lol ). I will comtinue to watch and be inspired by your vids- never stop exploring and grow, the TH-cam world is a better place with you! :)
great video , I never even knew the super pinda or the strain gauge existed , so can the pinda be used on an ender 3 pro? and is the pinda the only one that doesn't work on a glass bed? Also funny thing is that I saw some other videos comparing the BL touch to the CR touch and the retraction was worse on the BL than the CR , I was going to pick up a CR touch for my ender pro 3 (my first 3D printer and I have not even unboxed it yet) my local microcenter had one for $39 open box last week so I was planning on going there this week and I checked the stock again today to see if they still had the open box one , to my surprise the stock for open box now says 3 instead of one! so it looks to me that these things are being returned quite a bit for some reason also never knew the 3d touch was so cheap maybe I will just go with that instead unless the pinda can be used with the ender 3 pro , but then again if the 3d touch works on glass bed then maybe I should go with that one in case I decide to update the bed later on
I tried ordering a Super Pinda from Prusa. They would not sell one to me because I don't own one of their printers. I ended up with a BLTouch for my Elf.
Nice video & I just found your channel ( and subscribed ) Out of curiosity what do you use all your printers for, is it a business or just a TH-cam hobby. Not that one is better than the other , just curious. Ps - I also learnt some new things with excel too …
Obrigado, vou compartilhar com a comunidade brasileira, tava com o CR touch no carrinho para comprar, mas deu pra ver que é um produto de qualidade duvidosa.
I'm Surprised by this. I find the BL Touch to be flaky. It often fails during self test, and randomly during leveling. I have NEVER had my CR Touch, Fail at any point. Your CR TOUCH does appear to be slow to respond. You may have a bad unit. I have a BL TOUCH, still in use, and, when it dies, I will replace it with a CR-TOUCH, though, this was very interesting, and I will have to keep my options open, with all this detail in mind. Nice work.
His test as the advantage of moving the head, which would check if it has an impact on the precision. I would say this test and a M48 at the end to check the deviation would be a great addition :)
This lady is a billion times smarter than I'll ever hope to be! 🤣

When probing, the Z-axis start to lower, and CR-Touch pin touch the bed, and it will only go low enough that the pin will dip about 1/8in (1mm), and the LED colour will change and Z-axis start to rise. So my CR-Touch doesn't need to go low enough to trigger the pin to "retract" all the way in. So possible you have a defect CR-touch.
Could you be using Jyres HS (high speed) firmware? That enables the probe to not retract after each probe point.
I have a CR 10S Pro V1 which came with an conductive sensor i had a terrible time leveling, so I switched to an Inductive sensor. Based on recommendation from Make Muse. It has worked good then i switched to a glass bed and had to adjust so close to the glass it was a problem if a part warped. So then I went to a composite bed plate and glue stick. Recalibrated, releveled the table, the machine frame and tightened the bed springs. Now i get very accurate level. I want to repeat your study to see how accurate and repeatable it is. Can I beg for the excel Template?? You guys are so good. I share your video with friends. Although you talk too fast for my old ears I just replay that section and I can get it. I am learning from you guys every video. the oven knob and Fan blade was great. I also use Fusion 360 and OctoPrint on my 1os Pro V1. I did add struts too you may want to see what I did it stiffened the Z by a LOT. 10X or more stiff. Take Care you guys, tell Mom & Dad Hello, You have great Genes. D
Sure, here you are:

@@AuroraTech Thank You So Much, Hey I slow the speed to .75 and I can hear you perfectly!!!!!!! Thanks D
It looked like you only tested the cr-touch on a magnetic build plate. Might try testing it on a glass build plate, the magnet might be influencing it a bit.
My results are better than the bl touch results she comes up with. CR touch on glass bed. Ran 5 cycles to achieve a sum average then repeated the whole process 5 times. My CR touch on a glass bed after 25 cycles comes to a 1.18% average.
@@chrisramey5033 Your not the first person I have heard make the claim that the cr-touch is more accurate than the bl-touch. This is why I think the magnetic bed she used may be influencing the results.
I am happy with the $11 3d touch kits I have been buying off Aliexpress and will continue to purchase what is cheapest, so it dosnt really matter to me which one is more accurate. I would like to see the test repeated though with two different printers that are identical in all ways except for the bed, mostly just out of curiosity.
I actually had to take my CR touch apart this week and fix it because the metal probe was slightly bent and was getting stuck in the sensor causing a blinking red light and no function. Really disappointed with it especially after seeing the results of this video. I feel like they could make it really accurate with some more thought put into it
Impressive attention to detail and a pleasure to listen to. Keep it up!
Great job explaining your material. You're a natural presenter. Keep it up your channel will be a success, I have no doubts.
Thank you for the stright forward explanations and the added Excel tips! I have an old MakerFarm Pegasus 12 I"m upgrading to add mesh bed leveling with the BL Touch. I wished this video was available a year ago. I would have purchased the cheaper 3D Touch knockoff. :)
Hi Aurora Tech, could you do a installtion and config of the SuperPinda style sensor on a Ender 3 v2?
On v-core 3 i had problems with 3d touch, because bed leveling have 0.02mm tolerance. My 3d touch had deviation around 0.021, after turning screw i got deviation around 0.005 and i was able level the bed, but i also ordered original bltouch, just for sure and consistent deviation.
M48 for my cr touch result is 0.004250 it measure same spot 10 times. Also probe doesn't moving all way up, it stopes after light is on
Hi, can you help me connect the superpinda to Ender 3 S1?
There is a Marlin command M48 to test the probe's repeatability, the methodology it uses should give the right result because the testing method in this video has many factors to affect the final result.
Do you have or will you do a video on the Autolev probe installation and setup please
Yes, I have made a few videos for that. Please check the 3D printer upgrade playlist.
@@AuroraTech I’m one of your subscribers and I looked at all your videos, but I couldn’t find any on the Autolev brand bought from Substanica 3D. I’m a older gentlemen and not the best at the computer. Each time I watch the TH-cam videos they are older and the screens have changed so it is confusing. I’ve watched your videos and you explain thing very well and have had some success with your instructions. I need assistance to get this probe working on my Ender 3. I’m terrible at downloading and getting into my machine. I would appreciate any assistance available in helping me or a place I can get the assistance I need. Thank You keep up the good work
This is not one of the major leveling sensors, but I saw they also have instruction videos on their site:

@@AuroraTech Thank you I really appreciate the information
I’d like to see all of these tested using the same firmware. I’m using klipper and I have the crtouch not retract the pin while probing. It seems like it would be more consistent that way.
Hi! Thanks for your video. I was wondering if you can give me some directions with my cr-10 max. It's been an awful experience. I don't know if the fact that the printer comes with such a big bed, it's part of the incovinient.
Very helpful, gives me things to think about for my next printer build.
That's a great compression video!
Thank you
Thank you for sharing this academically rigorous experiment. You have helped me make my decision about which Bed Leveling Sensor to purchase.
you can paste the data in excel and use "text to colums" from the data tab; select space as a delimiter, apply and delete unnecessary cells. that way you dont have to do all of the time consuming stuff manually
Great video. Ideally, testing would be performed on the same machine and build surface. I've had mixed success with the 3dtouch - unfortunately there are multiple versions being sold. The older '2.0' version was problematic - poor precision due to play in the play in the probe, and inability to 'stow between samples' (in Klipper). The newer '3.2' version seems to have fixed these issues, and I now get comparable performance to a genuine BLTouch on an Ender3V2 for a fraction of the price. I don't know which version you've used in this testing - your mileage may vary.
I haven't tried inductive probes or strain gauges.
👍 Good stuff!
Lets be honest here though, its barely a difference lmfao.
I have a cheap ahh ender 3 with a cheap ahh 3d touch.
Its impossible to tell the difference between that and a bamboo labs.
The motors along with the electronics along with the firmware, are all the same. With the only difference being the frame and random features.
Is it possible to replace the strain gauge to a bltouch in a cr10smart printer?
I can't believe, how Průša called his sensor! :-D. I can't tell you what it means (in his language), since there are kids involved in this channel... He has a lot oof sense of humor, making this word say half a world :-)
Great job, the CR touch retraction is controlled by the CR touch after triggering, the retraction speed should not affect accuracy, but different amount of probing points and different printers and control boards will. Better not use 4x4 probing
Wow! Greaat testing method and data! Thanks!
My CR-10 Smart Pro when auto leveling the CR Touch drops twice for each point, once it moves quickly and the second time moves much slower. I noticed that in your video it drop only once per point. I wonder if this has anything to do with the poor result.
Another one knocked out of the park. Always look forward to your videos
Killer info, EXACTLY what I was looking for. Thanks!
VERY PROFESSIONAL REVIEW. You have a valuable talent.
First time viewer here, I was taken aback by his young the host is.
Damn, young generations are getting smarter by the day; is this what it feels like to be middle aged? Despite me only in my 20s
Can the Prusa sensor be used on any printer? If so, is it more difficult to integrate ?
Quiero instalar cr touch en artillery X2 alguna idea?
Hi. Do you have the ender 5 firmware with cr touch you can share?
Great job! Thank you for sharing the data and showing your calculations... that is super helpful.
My CR-6 SE strain gauge accuracy is 3.20% (using this method) yet I can't get a perfect first layer....
nice!! now i know which to buy for the Ender 3 Max at home! thank you Xiao Aurora
You saved few $! Thanks a lot. I have a BL touch knockoff and although it works well I never liked the plastic needle. I am always concerning that the tip will eventually melt at a certain point during probing.
Will the Prusa SuperPINDA work on BIGTREETECH mainboards??
I have a quick question, I still have either the old 8/16bit Silence MB for each of my Ender 3s. Will the BL touch will for it?
Also THANK YOU for this guide! Straight to the point, Data to back it up and variations to results considered! Couldn't ask for a better guide!
Excellent job! Well spoken. Keep up the good work. Thank you!
It would be interesting to run the CR Touch on a non-magnetic build surface to see if the metal probe responds better.
I wonder where the ezabl would have landed.
Thanks. I had the creality one in my cart. Desperately trying to fix a warping issue but already threw a lot of money at it so trying not to order this unless the other parts don't help. At least if it comes to that I know which one will be accurate!
Will super pinda work on Sovol SV01 or Ender 3 v2?
I'm about 90% certain it's not me, but I've had 2 bltouch and 3 3dtouch units fail on me shortly after installation...I mean VERY shortly! The longest one was a 3dtouch that lasted about 2 ½ days. I tried them on 2 different printers, so it can't be the printer's fault, right?
I have around 10 printers, using different ABL sensors, including both bltouch and 3d touch. They both worked fine for years, with no issues at all. No offense, but... besides the printers, sensors, there is another very important variable...
@@georgecarter5664 maybe you can give me an idea why then? They all behaved the same way: worked initially, then started the fast blinking thing and stopped accepting commands even after power cycling the printers. Two of them then quit entirely after that, not even lighting up. No one I've spoken to can figure out why, and I can't find anything online that explains it either. Thanks! 🙂
@@MAGA_Patriot2024 Maybe you must check the voltage, some of those device only work on 3.3v and the most recent can accept up to 5v
this is some incredibly qaulity content right here!
Damn almost bought the CR Touch good thing I watched this
I tried one of those 3D Touch clones and couldn't get reliable results from it. I suspect that there is a little bit of luck involved in getting a good one.
In Canada the crtouch can be had for a third of the price of bl. I think the prusa should be excluded from this because the barrier to entry for most people to buy a prusa is 3 to 4 times the price of printers with similar print quality. I knock prusa alot but if you live in Canada then you'd understand. Plus they haven't evolved at all because they have such market dominance that they don't have to. It's holding the whole consumer level printer market technology back by years because everyone plays flow the leader.
Ask yourself this question, when will people without any technical know how be able to buy a printer and plug it in then be able to open a file and press print like you can with an ms word document?
i'd love a strain gauge made by prusa, seems like they are on top of the ABL game right now. but i just low how you can't even tell there is ABL on the strain gauge by CR
It is very useful. Thanks for meaningful job!
This is calculating the repeatability, or precision (not accuracy). but great job at applying stat in this comparison. 👍
why you divide by 0.2 because this is 100% of layer height?
Did you factor in the Z positioning accuracy of the printers?
It would be interesting to see how the CR-Touch would perform if you used it in Marlin's BL-Touch "Fast mode", i think it would have performed better.
I have a Creality 4.2.7 board and using a CR Touch.
Works fine but starts to slow blink after it starts printing.
Is that normal or is there a way to make it stop?
(Update) I tried a different CRTouch. That was a loss of money it did not make any difference.
I got it fixed by turning the internal pull up resistors on my board.4.2.7 and 4.2.4 Creality Motherboard. PB0 and PB1. By adding this to my pins_CREALITY4.h at the end of the file #define BOARD_INIT() SET_INPUT_PULLUP(PB0) SET_INPUT_PULLUP(PB1) Thanks to Scott Lahteine
Very informative, I was about to spend on clearity, now it’s a big no. I’ll go with Bl touch thank you for the info.
Impressive assessment and delivery! I'd be interested to see if the CR Touch is just a bad sample. Excellent work 👍
Very well done and informative!
Very informative and well presented. Thanks
I bought a 3d touch a few months ago. It just gave me an error the moment i plugged it in.
i have an cr-touch on my ender3(4.2.2) and don´t find it much slower than my previous bl-touch
(the retraction speed of the sensor has no influence on the measurement result, since it only depends on the triggering time when the sensor starts to move, how long it then takes to fully retract is irrelevant )
with the m48-command i get 0.001250 on the cr-touch, while the bl-touch was around 0.004500
i´m not sure if the m48 is as accurate as your measuring method
greetings from germany
CR Touch pin shakes like crazy! When printing. You're readings of the CR touch are totally correct. 👏 You are doing awesome content subbed and will follow your new videos.
You videos are great keep it up!
Nice review.
Good in depth test.
hello you forgot the EZABL from TH3D
I really enjoy your channel. You present the printers and other devices with clarity. Much better then most of the 3d printer reviewers on here. You are amazing at such an age ( I'm only guessing you are younger only because in one video you mentioned your mother would be upset by using her microwave as a kiln-lol ).
I will comtinue to watch and be inspired by your vids- never stop exploring and grow, the TH-cam world is a better place with you! :)
great video , I never even knew the super pinda or the strain gauge existed , so can the pinda be used on an ender 3 pro?
and is the pinda the only one that doesn't work on a glass bed?
Also funny thing is that I saw some other videos comparing the BL touch to the CR touch and the retraction was worse on the BL than the CR , I was going to pick up a CR touch for my ender pro 3 (my first 3D printer and I have not even unboxed it yet)
my local microcenter had one for $39 open box last week so I was planning on going there this week and I checked the stock again today to see if they still had the open box one , to my surprise the stock for open box now says 3 instead of one!
so it looks to me that these things are being returned quite a bit for some reason
also never knew the 3d touch was so cheap maybe I will just go with that instead unless the pinda can be used with the ender 3 pro , but then again if the 3d touch works on glass bed then maybe I should go with that one in case I decide to update the bed later on
I tried ordering a Super Pinda from Prusa. They would not sell one to me because I don't own one of their printers. I ended up with a BLTouch for my Elf.
Thank you Aurora! I will Get the BL Touch
Nice video & I just found your channel ( and subscribed )
Out of curiosity what do you use all your printers for, is it a business or just a TH-cam hobby. Not that one is better than the other , just curious.
Ps - I also learnt some new things with excel too …
Obrigado, vou compartilhar com a comunidade brasileira, tava com o CR touch no carrinho para comprar, mas deu pra ver que é um produto de qualidade duvidosa.
I'm Surprised by this. I find the BL Touch to be flaky. It often fails during self test, and randomly during leveling. I have NEVER had my CR Touch, Fail at any point. Your CR TOUCH does appear to be slow to respond. You may have a bad unit. I have a BL TOUCH, still in use, and, when it dies, I will replace it with a CR-TOUCH, though, this was very interesting, and I will have to keep my options open, with all this detail in mind. Nice work.
Hey so just an update marlin setting search m48 and enable it and just send m48 in octopi
His test as the advantage of moving the head, which would check if it has an impact on the precision.
I would say this test and a M48 at the end to check the deviation would be a great addition :)
