Wow, this is the EXACT video on replacement boards I've been looking for! This helps me feel way more confident about doing this myself on my CR-10. THANK YOU Aurora for another AMAZING video! Your videos continue to surprise and impress me. You're content is better than 90% of the other youtubers out there, and you clearly put in a TON of prep, filming, and post-production / editing time and effort!

I wasn't looking forward to this. Nobody else made it this clear any easy to follow. Well done. Thanks

Out of all the videos and articles I've read while trying to install my SKR and TFT35, this was the most helpful, so thank you very much! Keep up the good work!

I’m late to the action but I’ve been fighting this bl touch for 4 days and as I was about to say screw it and go back to the OG parts I found this video. Much love.

I have been wrecking my brain trying to do this exact thing all day, and you just made it look so easy! I really appreciate the wiring diagram stills with the pints labeled. Thanks for the video! Hope to see more of your videos!

Thanks kids! Even after 2 years the video is still relevant. I decided to do some maintenance to my Ender 3 Pro with an SKR Mini E3 V3 and tidy up all the wiring for the BL Touch and add a Creality light kit. I think I've had my Ender 3 for about 5 years and the only problem I've had with it was the original controller board quit working so I replaced it with an SKR Mini V2 board, then upgraded the V2 to a V3. You videos have been helpful, thank you very much for taking the time to make them.

This is the exact video I needed to see. I want to upgrade my ender 3 max stock 4.2.2 board with the mix of silent and loud steppers to an all silent board and have been debating between this, the v2 verson and the 4.2.7 board. Thank you so much for sharing!

I was looking for a video that explained how to replace the stock board on my Ender 3 Pro with the BTT E3 v3 and how to connect a CR-Touch properly. After a few videos I found yours and I'm glad I did. You put time and effort into your video and it shows. Very clear information and explanation! That alone earned my sub :-)

I think you are the only person who has solved the BL Touch problem. You did it because you have the experience of installing the version 2 BLTouch. Whereas BTT is assuming people will install the Version 3 BL Touch. Well done!

HOLYCRAPBOTZ! BEST DAMN 3d printer tutorial EVER! specific, to-the-point, no BS-ing around! if you are here to SPECIFICALLY learn step-by-step how to install the Big Tree Tech SKR Mini E3 V3.0 and 3.5” touch screen - you are in the RIGHT spot. her narrative and accompanying production design alongside her SHOWING you where everything goes is better quality than i've seen of these types of videos. (believe me - i watch a LOT). why is it so far down in the you tube search quarry? this is the best one. - seriously, it is. this girl knows her stuff!

This may be my favorite 3D printing channel on KZfaq!!!! Great job!

A+. Appreciate that you kept your trouble shooting logic in with the BL touch and the firmware in the video instead of skipping to "just do this". Going to order this board now!

I installed my new board a couple of weeks ago and it was a total nightmare. I couldn't find a single video or article explaining how to do it and ended up with three tabs with different wiring diagrams in each. I'm now trying to install a BL Touch and stumbled across you and I really wish I'd found you when I was installing the board! This is exactly the information I needed, presented in a clear manner. Thank you so much! I will definitely be coming to this channel for info on further problems.

Ordered a mingda magician pro based on your great review. Now I'm looking for resources to upgrade my ender 3 pro with bl touch to the skr mini e3 v3 with tft and came across this video. Really great and clear video and is exactly what I needed. You earned a sub, keep up the great work!

My board will be arriving in a few days and I will definitely be referring to this very detailed and informative video to get the upgrade done. Thanks Aurora & Helios. Amazing job.

This is the most thorough review I've seen, really exceptional job.

Great video! I bought the Creality 4.2.7 silent board for my Ender3 only to have the bed mosfet fail. I replaced it with BTT board just as this video shows and it's been great. One of the best pieces of advice is taking pictures of original board connections before starting. This is great advice before doing anything you're modifying. I work on motorcycles and document steps start to finish.

THANK YOU!!!!! I was pulling my hair out! The whole reason I went with BTT was because Creality tends to have firmware issues they don't address, and BTT had a lot of positive videos on KZfaq. 🤬

I have been struggling with the Ender 3 Pro with the BTT SKR Mini E3 V3.0 and the CR touch for a while. This was the fix. Worked beautifully. - Updated BTT TFT Firmware - Updated BTT SKR Firmware (with Z-Homing) - Swapped the pins per video instructions. Thank you! :)

Awesome video! I will be completing this upgrade for my printer tonight and this video has me well prepared, thanks!

The best explanation on how to replace the motherboard and start printing after do it. A thousand thanks!

Literally just got this board in for my ender 3 pro. What a great video much appreciated

Absolute life saver Just fried the mainboard on my used printer and had no idea how to even start to approach this.

OUTSTANDING! Thank you for your time in making such an excellent video!

I got the V3 board for my Ender 5 about a month ago now, had to recompile Marlin to get bl touch and RGB leds going plus temp over run safety features. Works like a treat, very happy with it.

What a great video. Thanks to this video and the comments/description, I figured out what was wrong after I had somehow connected the three fans incorrectly, resulting in frequent heat creep due to the hotend fan not being switched on correctly. This video explains the upgrade process much better than the official video. I like the added schematic so it's easy to see exactly what connector you are talking about.

this is by far the best guide I have seen. you are awesome!

Thank you for an excellent, and very instructive video, I have been trying to get my CR Touch working, with my SKR Mini E3 V2.0, and you have found the solution. I now know where to look for the next time I run into a problem with my Ender 3 printer. You have a channel to be proud of!

Thank you! I've spent hours trying different firmware to try to get my BLtouch to work, thankfully I already had a box of JST connectors laying around so this was an easy fix.

Thank you very much for your solution regarding the CR-Touch! I have been looking for a solution to the Z-Homing problem for several days, I would never have thought of connecting the two wires to the Z-Stop. You were much more responsive than BTT support, who haven't answered me in over a month! Thank you again, keep it up, your videos are really very interesting!

Tremendously helpful especially the RS232 connector orientation on the board pins! Exactly what I needed. I was also preparing to connect the TFT screen power port to 5v on the board but it appears to be unnecessary!

I want to take a moment, To thank you. From the bottom of my heart, Thank you! You keep making content of this quality, You are gonna take over the world.

Amazing video! you showed everything and more that i needed to see, and the pinouts beside the video wer super helpful. you are going to make a ton of money in tech some day

Straight to the point of what you need to do, That what I was looking for. Thank you ☺️

Amazing video. Clear instructions and awesome explanation. Keep up the amazing videos.

best video I found on upgrading to this board. Thanks!

hitting same issue with the cr touch. hope this works - Thanks for all the great content.

Really nice video! would love even more Ender 3 pro content

OH MY GOD THANK YOU!!! 3 hours spent looking through Reddit posts and random websites and you answered my EXACT question in less than 10 minutes! Subscribed!!!

Very nice video. I used the TH3D Studios unified firmware. It cost $5 but worked on the first try and didn't require changing the CRTouch wiring. They probably had not released this firmware at the time this video was made.

you and your bother are amazing and informative. thank you for your wisdom and kindness :)

I’d like to point out that the fan2 port should be for the motherboard fan and the fan1 port will go to the hotend heat sink fan, so the video needs to point that out because I had tried configuring it similar to the video but my hotend fan would never turn on. Hope this helps!

Very knowledgeable and I had no idea the fan could be converted to a JST. I’d love to have the fan turn off after a print so I’ll be buying some connectors

ive been looking for a video like this all day thanks for the super descriptive video

Thank you for your video, perfectly paced and with all the information explained and shot with an eye to thoroughness but avoiding being repetitive and tedious. I have just bought the BTT mine E3 v3.0 for my E3v2 and am at the moment wiring the LCD cable. I have experience crimping and have the tools as you have (although yours look novelty oversized but i think its the small hands) and bought some IDC blanks and had some suitable ribbon. There is still the other end of the adjusted lead which needs the wires rearranged and put into a plug with crimped connectors. So it isn't for the faint hearted or time poor. In fact the idea that this is a "drop in board" is a little misleading as there are obviously moderate level tweaks to the fw and significantly more involved faffing about with the E3.2 LCD lead.

Great video, I upgraded the v1.2 board in my E3Pro to the newer v3 last December, and the only issue I had was that the stock firmware did not like my SD card being formatted to FAT32. Once I reformatted to FAT16 and applied my own custom firmware I was able to switch back to FAT32. I based my own firmware on the bugfix-2.0.x from Marlin direct, there are v3 BTT configs already available, I added my own tweaks for the TFT, BL-T, NeoPixels and smart runout sensor plus other things, and it works like a charm. Being able to finally shut the hotend fan down when below 50c is wonderful as well as better control of the board fan.

I had a feeling the BL Touch issue you show here was related to the port not being supported correctly yet. I almost tried switching it to the z limit port but hadnt yet as i was waiting on some fans to do all my wiring at once. Looks like ill be switching my wires on the connector to a JST :) Thanks again for your videos. Now to find a Orbiter mount for a Aquila with a v6 :)

I could unsubscribe all my major well known 3d print channels because you are combining the whole worldwide existing 3d printer knowledge.

Waaayyy better than any other video out there thanks!!!

Nice tutorial, thank you Aurora.

Gawwdam hella knowledge!! I’m definitely going to upgrade to this silent board, pancake extruder and run out sensor

I subscribed after the first 30 seconds.. outstanding video!

thank you for helping me get the touch working

Thank you! I had this issue. For SKR E3 mini V2 it worked in the BLT connector, but for V3 it does not. Going to try this :) Thank you again!

Great detailed video. Thanks so much.

Thanks, I had the exact same problems using the BLTouch Z homing firmware provided on BTT's github. I moved the 2 wires to the Z-stop plug. Might I add that you should mention that if the wires are reversed, it will continue to drive the nozzle down even when the sensor is tripped. Simply reversing the wires solves this. I did this, as my wire colors were totally different than yours. I knew what to do because I had to reverse the wires when I installed a BLTouch on an old CR-10 years ago.

A truly impressive and informative video.

Thank you!! This video is 10000 times better then BTT's video guide.

Best video about this that i seen. Thanks from Brazil

I thanl you from the bottom of my heart. Saved me tons of hours

The touch screen firmware also comes with several different icon theme packs. I prefer the Round Miracle Menu Material theme, so much nicer than the default square icons. Just add the folder to the SD card when updating the screen firmware.

Awesome! Very nice explanations. Greetings from Spain.

Great explanation, wish I would have seen this before sending it.. would have saved some head scratching for the fan connections 😂

THANK YOU Aurora!!!

Recently upgraded my firmware and kouldnt get it to auto home what so ever YOU SAVED ME lol thank you

thanks for the bltouch solution!

Awesome video 😎👍

Awesome videos as always! Can you do and show some upgrades to the sovol sv01?

Awesome video!!!

Another great video, but you missed something special. Using the touch sensor as the Z stop, you can replace the springs for posts and never worry about your bed again! Perhaps you can do an update. Instead of trying to cut small tubing to exact lengths, you can just fill the existing screw with common hardware store nuts. Then with a final locknut under the carriage, you have identical length posts. The only worry is the carriage wheels being sufficiently tightened to avoid wobbles. If you try it, please make an update video. Keep up the good work.

very detailed, easy to follow and reproduce information. Again, I learned a lot. One question remains: does this board with this massive heatsink still need a mainboard cooling fan? Well done Aurora and Helios, Fan-Tas-Tic

I'll be adding this board and some updated screens to my 2 Sovol SV05 printers.

Thank you very much!

I've been in electronics/IT world for 25 years, I've never been sold on Ferrels, to me its better to allow the wire strands to spread out within the clamping mechanism, allows better connection.

Really clear and excellent presentation (as always)! Is there a more current firmware upgrade that includes the bltouch and "normal" wiring?

Great video!!!!

BTT should link to this video for install. Also you should tag the cr touch in the description to help people find this solution.

Thank you!

Awesome video thanks so much. only 1 question you were so thorough on everything except if we want to use marlin mode which port do we plug into??

Very informative video as always. A bit of emotion or enthusiasm during the long dialogues would be appreciated. Very happy with my Ender 5 Pro thanks to you 👍

An excellent video, very well presented and easy to understand; thank you for sharing! 🙏 Do you have a video showing how to add the BTT SKR Mini E3 V2 board to a CR-20 PRO and connecting the CR-20 LCD screen to the SKR Mini?

superbe vidéo , merci !!!!!!!!!

THANK YOU SO MUCH

Great video Aurora. I have the BTT V2.0 board in my Ender 3 Pro. I just installed the dual Z axis upgrade and saw there were 2 Z ports on the BTT V2.0. The cable that came with the upgrade kit is a splitter cable. I wanted to find out if I should run a separate cable from each Z port to each Z axis motor instead. I didn’t realize it until I watched this video that the 2 Z ports are coming from the same stepper driver. So now I know that the one stepper driver can handle both stepper motors. You have a new subscriber.

Thank you so much

You might want to add a link for the Ferrules and crimp tool as well. I just purchased those and would gladly use your link for those as well.

Wow! Best video I've seen on this...well done, you made this super easy to understand. Do you have a video that explains how to modify firmware now that it is released? I cannot get firmware to compile is VS Code to save my life. Just trying to comment out the Z limit switch.

Loved the video! I did run into one issue though.. I did everything and followed you step by step. I connected my bltouch using the 3 pins on the bltouch port and the 2 pins on the z limit, but when I try to auto home or anything the z axis goes down to the bed and it doesnt stop it just keeps trying to lower

Best video explaining the problems on the SKR mini E3 V3 board! Thank you!

Usually pronounce ARM processors as like your actual “arm”. Nice video ✌️

Good evening Aurora, I follow with great interest your videos and congratulate you on your work; Would you be able to make a video on the installation of Klipper with the sonic pad on the SKR mini E3 V3 on an Ender 3 pro. That would be great for updating my machine. Thank you in advance

Your Video, explain the bltouch and crtouch Problem thank you

Had the same issue with skr mini e3v3 and cr touch, i compiled a marlin fw and got it to work without removing any pins. So it can be done without hardware modifications. I think i enabled z safe homing and z homing probe and bl touch. Great video nevertheless 👍👍

A quick note for those running klipper, the touch screen offers no advantage over your stock screen. It will only work in marlin emulation mode, no touch screen unless you have marlin firmware.

Thank you for the video, it's well done like the rest of your videos. What is the pitch on the JST connectors you used for the fan? Do you have a link where I can order these? Also a link for the crimper and furrells? Thank you!

Thanks for the amazing video! Do you know if the firmware issue with the BL touch has been updated yet? Thanks.

Nice you made a biqu b1

I installed this same board to my aquila with a tft35 v3. Everything worked great with also a smart filament sensor connected to the board. Up until I upgraded the tft35 firmware which removed the smart option from the filament runout on and off button. And now I get filament runout warning everytime I try to print.

Thanks for the video! Do you think this would be worth installing on a Voxelab Aquila?

I used this fix with my bltouch and it worked great! Thank you so much! I have one question. When I flash the firmware.bin to my board, it overwrites all my changes to marlin. When I flash it again with my fixes, it overwrites the bltouch fix and it stops working. What was changed in that firmware.bin that made the bltouch work?
