Creality 32 bit V4 board guide - Ender 3 V2, BLtouch & more

[@thecampbells8705]

For anyone struggling with a 4.2.7 board and using the 5 pin BLTOUCH connecter: I followed the video, and after uploading, my Z axis would only go up during auto home. The solution was to COMMENT OUT //#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN and UNCOMMENT #define Z_MIN_PROBE_PIN 32 // Pin 32 is the RAMPS default. Michael, your videos are the BEST.

[@MiroslavKastak]

I tried both ways and my ender 5 pro with 4.2.2 motherboard still won't homing 😟The bed just go down but never go up even if I try it manualy from display. Any idea what I'm doing wrong ? I use Creality BLTouch vith 5 pin conector

[@ryanpeinhardt602]

Heads up: at <a href="#" class="seekto" data-time="495">8:15</a>, the call out on the right side of the frame is capitalized differently than the actual code on the left side of the frame. "STM32F103RET6_creality" as shown on the left is correct. The project will not compile if you use STM32f103RET6_creality as shown on the right.

[@37Kilo2]

Thank you! This was preventing me from building the firmware.

[@37Kilo2]

Spoke too soon, now I get: Environment Status Duration ---------------------- -------- ------------ STM32F103RET6_creality FAILED 00:00:00.669

Thanks for that. 2 hours of searching and a lowercase f was the cause. Just like working on my own code

[@hosjmanne]

[@OfficialRandomGaming]

you beautiful soul!

[@thomasalkhoury4434]

A note: Recently, I tried using the environment variable STM32F103RET6_creality, however this has failed when building in VSCode. The reason is because Marlin has changed it to STM32F103RE_creality. Use STM32F103RE_creality for newer versions of Marlin. Also, if you get an error about FAN_SOFT_PWM, make sure to go into the config file and uncomment FAN_SOFT_PWM line

[@junjieshen9985]

A quick reminder for those who purchased the Creality BLtouch kit: The cable provided by the kit does not work with Ender 3 V2 because they change the GND and VCC orientation. I did not realize this when I tried to install it and I fried my mainboard. A quick fix: you can swap the blue (GND) and red (VCC) cable by using a tweezer. Use the tip of the tweezer to pull up the black plastic behind each cable and swap them. I tested mine, everything works now.

[@MathieuGosbee]

Yep, same. Works now.

[@associaleAle]

same here, but I read this comment after I fried my mainboard :(

[@snecklifter]

Also fried mine, yaaaay!

[@chiefsmallrod881]

my board smoked up but i shut it off immediately and swapped the wires after reading this and it didnt smoke when i turned it back on... am going to test under close observation and see if boards actually fried or not. Probably going to order a new one anyways

[@gr7396]

Sorry this happened. For next Time and others that may trad this, Creality has a video out showing the pins being reversed when using their kit on a e3v2 and swapping them Many older BL touch videos for the e3 and e3 pro, Michael may have covered this then, covered making sure the wire pins were in the correct order when using the pin 27 board. The Smith BL touch firmware download page has pictures showing different long wire extensions and what the pin order should be. I do a lot of research before any wiring or accessory change/install. I’ve learned from my mistakes to make the time.

[@andrewsc7304]

Thanks for this amazing guide. Just wanted to mention, as of right now, uncommenting Serial Port 2 causes compiler errors, and the build fails. I have just set Serial Port 1, and left the 2nd commented out, and it worked flawlessly on my Ender 3 V2

[@gsiens5163]

thank you so much 😭

[@TeachingTech]

UPDATE: This seems to be working for people with the 4.2.2 and 4.2.7 boards. When adding a BLtouch, please actually use the provided wiring diagram! Too many comments here about just plugging it in and frying boards. The (colour coded) diagrams I provide are to avoid this from happening so please use them. Two corrections: 1. When specifying the environment in platformio.ini, I should have had a capital F in my graphic: STM32F103RET6_creality 2. The CR-6 SE has a different board. Thanks to Sebastiaan Dammann for the following information: "The CR-6 board is supposed to have TMC2209 drivers and not TMC2225. The TMC2209 drivers were a Kickstarter stretch goal - which has been reached. You can see a picture of the TMC2209 driver here: facebook.com/groups/cr6community/permalink/907195406473518/?comment_id=907405066452552&reply_comment_id=907736776419381 II don't know how these drivers are connected though (UART or standalone). Also, the board version is v4.5.2 - not v4.2.7. Check this: facebook.com/photo/?fbid=10157803199746200&set=g.839170129942713 Since there have been multiple cases of the stepper driver in the top right of that picture - for the extruder I guess - burning out, it may be possible a new revision of the board is being developed. The CR-6 board also has an extra stepper driver because it has two Z-axis lead screws."

[@eekovalev]

Why don't you replace 'X_DRIVER_TYPE TMC2208_STANDALONE' and others with A4988 for non-silent v4.2.2 boards?

[@ChrisKoups]

They are 4 pins underneath for G-DIR-STEP-EN so I think that is the legacy mode... Is it?

[@seanawesomemega]

Do you need to re-align the wires on the bltouch side as well, or just on the motherboard side? I reset the wires on the motherboard side and the bl touch responds (test probes, and will blink if it's too close to the bed) when I turn the printer on (installed the 4.27 custom firmware you provided) but it doesn't probe on command and can't be controlled from the settings

[@kh0sa]

I just upgraded to SKR Mini 1.2 on all 4 of my enders. Love that board!

[@VVinoh]

Did you try the SKR on an Ender 3 v2 with the DWIN color display?

[@troykirchenbauer]

I did the whole kit upgrade from my ender 3 pro, the 4.2.7 board, new LCD display, BL Touch and filament runout sensor. It was my first time compiling Marlin firmware and I had to build the visual studio setup. I am very grateful for the video. It was well done but did leave me wondering how the heck to install the filament sensor other than just leaving it hanging in the air. Of course I took my printer apart before realizing I needed to print the BL touch mount. After putting it back together with the new board to print the mount, I realized there is likely a mount for the sensor. My biggest challenges were needing to make the end for the z axis plug in from the parts in the BL touch kit at the extension cable had a three prong plug, not a two prong plug. And, my other challenge was not listening with Michael said that the Z offset setting that worked for him was 2.something. I was moving it .10 to .30 and I could not see it move at all. I assumed I had done something wrong, but after going over it all again and again, I finally found a post were someone pointed out that the adjustment is very fine and you would really need to get after it to see it move. I did notice that the Z offset control does move the head just by turning the dial, you do not need to click. Perhaps this is a firmware change since Michael's post. All in, this took my the better part of my Sunday, but I am thrilled to have it working and appreciate the great video. Thanks!

[@kimberlylyon3738]

[@TheSelfdeterminant]

OK, I'd like to thank the living hell out of you. I spent time with your videos before really getting into the assembly and attempted first print so by the time I did the thing I just went for it. The print came out flawlessly and I can guarantee it was due to watching you and a couple of others. Patreon inbound.

[@VincentGroenewold]

Another update if you're using the latest bugfix releases, don't uncomment the //#define SERIAL_PORT_2 -1 line as this is now handled automatically. Otherwise errors pop up. Also, my extension cable had a 3-pin connector for the Zstop, while the Zstop on my board only uses 2. I took the connector of of the old Z stop connector (pressing down and wiggeling on the metal inserts) and exchanged those.

Another update; when using Klipper, it's best not to use the Z endstop for the BLTouch. It might work with the mod for that I guess, but I just plugged the BLTouch into the sensor pins meant for it (making more sense as well).

[@xPureL]

Thank you for the great video! Really clear and useful, helped me install the 4.2.7 (while I ordered the 1.1.5.) There were some things different than the video, but managed to get through them. I'll write them down, maybe it helps someone. 1. When copy&paste the files from configurations-folder to Marlin-folder, specific for the printer in use, the Ender 3 folder contained more folders than expected. The Examples>Creality>Ender3> has a CrealityV1 folder that contained the right files. 2. I had to install PlatformIO IDE 2.0.1 in VsCode. (also Build and Run 0.2.0 and C/C++) to get the 'build' button below in the blue bar. 3. When typing STM32F....etc... at the first VsCode edit, the letter 'f' is shown in lower case in the floating box. I did type the uppercase F, since that's what the printscreen showed. 4. After upgrading my Ender 3, all the motors went into the wrong direction. Nearly broke them. So my advise to others is to do manual movement of the XYZ first, by 1 step at the time, to see if the directions are correct. (Correct me if I'm wrong, but Positive numbers should go more Z-Up, Y-Back and X-Right.) But via Configuration_h around line 1100, i could change the motor direction by reversing the true/false. So all is fixed. Thank you!

Hey man thanks for going through the trouble of making this video. I bought a Creality Ender 5 Pro with the 4.2.2 silent board. I wanted to print carbon fiber ABS so I had decided to upgrade to a Micro Swiss Direct drive hot end, Bltouch, Big Tree Tech Smart Filament Sensor, Noctua fans with buck converters, Wham Bam Double Wham Flexible Build System, and 120 volt heat bed with solid state relay system. Doing this all at once! The physical install of these systems was the easy part, the firmware has been a whole different story. I have spent a couple of weeks attempting and failing at compiling the Marlin Firmware to support all this. After watching your videos about these systems I was able to finally compile a firmware that facilitates all of these systems

Perfect tutorial for my e3 v2 for the bltouch.

[@AmochaSagolsem]

I am new to 3d printing. I have ender3v2. I just upgraded my motherboard with v4.2.7 cuz the old one causes layer shifting. I tested the motherboard and it works fine but there was power outage and there is no resume function in this new motherboard. Can you please help?

[@olegs1437]

Thanks Michael! I got E-3Pro v1.5 about 2 month ago and it had excellent printing quality out of box. But I needed to print TPU parts for my main hobby (drones). Also manual bed levelling and stepper motors noise were irritating. So, first I installed some generic BlTouch clone, converted printer from Bowden to direct drive, and, finally, changed motherboard from Creality 4.2.2 to SKR MiniE3 v2. On the way I learned how to install VB, how to compile and debug Marlin soft. Thanks to yours videos (and I believe your videos are the best in this area) my way was far less bumpy than it could be. The hardest was BlTouch install as there were no clear explanations how to wire it up on 4.2.2 board. I had to open/close motherboard compartment at least 20 times and was ready to through BlThouch to rubbish bin. You released this video right in time to save me:) And thanks to another video of yours upgrade to SKR MiniE3 took only couple of hours and second compiled binary was fully working. Keep safe (I hope you are not in VIC:( ) and all the best!

Can you do a firmware video for an Ender 3 pro with an extender and BLTouch using a 4.2.2 board.

[@julienmolina9485]

Thanks for this video, it helped me a lot. I just upgraded my Ender 5 to board 4.2.7 and it wasn't as easy as I wished. I tried without modifying the firmware because the board 4.2.7 was supposed to come with the right firmware for my Ender 5 (It was a non modified Ender 5). Almost everything was straightforward thanks to your wiring diagram at <a href="#" class="seekto" data-time="270">4:30</a> but I had a problem with my extruder going backward. The first option would have been to wire the stepper motor differently but I found out that too many ppl fried their board so I choose option too : compile marlin. I followed this video but I had a few adjustments to make : even if I selected the Ender 5 default configuration a lot of parameters were wrong for me : - The home location was not correct => Auto home goes the wrong way for X and Y - The extruder was going backward - The Z axis steps / mm was 400 instead of 800 for my printer => The result of this looks like over extrusion (of course it's going down only half of what you want) Now I'm finally able to print again, the stepper motors are so silent now, It's just crazy. I think I have one problem left with the fans. The hot end fan is always on but the board fan is enabled only during a print. I think it should be the opposite but I don't know how to change that yet.

A big thank you for this tutorial on upgrading to a 32 bit board for the Ender 3. I just bought a Creality V4.2.7 32-bit board along with their touch screen LCD panel to install in my first generation Ender 3 that's getting a little functionally antiquated and was unsure of how to go about installing the firmware. In the past I had replaced my Ender's original 8-bit board with an SKR Mini E3 board which worked well but it failed after one month and BTT refused to honor their warranty for no particular reason so I reinstalled the original board to keep my Ender running vowing to never buy another BTT product again. Hopefully this new Creality board will last longer than a month and if it does fail, Creality will honor their warranty.

Hello everyone. Please exercise extreme caution when installing a filament sensor by following the wiring diagram in the tutorial. Pin 1 and 3 are reversed on this picture, on the back of the board it is printed correctly. If you're installing the bigtreetech smart filament sensor as I have the wiring of that cable is completely correct! No need to try and flip the pins, in fact it can damage your printer from what I've read. So I needlessly changed mine up and then had to change back when I noticed it not working. Thank you for the video otherwise, it's been amazingly useful for me as a beginner!

Another respons to this video, this time about the BLTouch for other viewers: I've installed bltouch as shown in the video. Then, when adjusting the bltouch height, I found out that the height has to be as followed: when the bltouch 'feeling point' is extended, it has to be lower than the nozzle, of course. But when retracted (that's what happens after a 'touch') it must be higher than the nozzle. An easy was is to start bltouch bed leveling, let it touch the plate our your hand, when the pin is retracted inside, turn off the printer. Then lower with the z-axis the nozzle to the bed, then adjust the bltouch height so it's 2-3mm above the bed. Then do your first bltouch bed level and let it complete. Adjust the z-probe when printing a flat wide object. In the video he says " minus 2.26 pretty ideal". But on my Ender3, older screen, I get the numbers 00.000 and then have to adjust. So I went adjusting to -01.000. Thinking this would be 1mm or 1cm. Next thing happend: I completely crushed my bltouch and nozzle into the plate. Broke it and probable made heavy damage on the z-motor! Luckily I could DIY the BLtouch and fix it, so works again. But not great! And therefor IMPORTANT: when you see your z-probe offset starting with 00.000, try to set it on 00.010 first, or maybe even 00.001. In my case, the 00.010 means 10mm. So I've got my Ender3 set on 00.016 for a good hight. Also, when printing and tuning the z-probe offset, the effect is inmediate while you set a number, so you don't have to press 'enter' to see the result. Just keep turning until the print is as you want it to be.

You just “chopped” that 8-bit board. Nice!

[@sarrieri]

First of all thank you Michael! I have the Ender 3 Pro and I have upgraded to the new motherboard v2.4.7, the trouble was when probing the bed, the BLtouch was probing outside of the bed surface. It seams to me as a problem that other users my have as well so here is my fix. In configuration.h #define NOZZLE_TO_PROBE_OFFSET { -43, -5, 0 } #define PROBING_MARGIN 15 You can play around with the PROBING_MARGIN values. Happy printing everyone, kudos to Michael again !

[@sarrieri]

Don't forget to install the auto build marlin extension too, it will help you a great deal.

[@rjvrensburg1809]

Thanks for this, decided after 4 years it was time to upgrade my old ender 5 with the new 4.2.7 board. One thing to note, if you had TL smoothers with the old board, take them out. They actually have a detremental effect on prints and noise coming from the steppers. The new TMC drivers do not want TL smoothers it seems. Also, found TH3D new firmware worked great, while I had some issues with vanilla Marlin.

NB do not set "#define SERIAL_PORT_2 3" if using bugfix or versions newer that 2.0.7.2 (when released) Newer marlin uses LCD_SERIAl_PORT and is automatically set to port 3 for this board and display.

Question: Will the Creality Color LCD from the ender3 v2 work with a BTT SKR Mini E3 V1.2 board?

[@MASTERERAZER]

This is a good question

Don't have the answer but potentially by looking at the pins files for the two boards it should be possible, defining what was required in the BTT pins file and then defining the Creality LCD as seen here.

Thank you for this information...Awesome! One thing I noticed with this upgrade, is that the stepper motors now have a little thump when powering on the machine, as if the steppers now receive a lot more initial power. It only happens when the steppers are in the home position, move them off that and the thump is gone. The prints are awesome, no noise!!! I have the 4.2.7 board in the Ender 3 v1 - Original.

[@tonykyle2655]

@Teaching Tech, Would like to know how it compares to the SKR Mini E3 v2.

[@spearview]

SKR mini v2 has tmc2209 in UART and this has tmc2208 in standalone. You can do linear acceleration and senorless homing with skr mini V2. The ender 3 4.2.2 board doesn't support those as the tmc2208 is in standalone (unless someone finds a way to solder a few wires and make it in uart which I haven't seen yet). Michael has explained this in his tuning linear acceleration video.

This fixed my issue with the new version of Octoprint by updating the firmware to Merlin instead of using Creality's OEM firmware on my Ender 3 V2.

Not sure if you have tried the Creality 4.2.7. I have fitted this board to my Ender 3 Pro also have a complete set of 3DFUSED linear rails and double Z drive. The v4.2.7 is so quiet when sitting at my desk within arms reach I have to check that the printer is operating when I don't hear the power supply fan running occasionally. I have the Marlin Bug Fix installed on this board In my opinion this is a great board. I have a SKR V1.4 Turbo board to install in this printer but I will hold of for a while to see how this board performs. PS FYI. I solved my previous problem.

Fortunately the board took over a month to arrive into Australia (never thought I'd say that), otherwise I'd have pulled my hair out!

[@corgano6068]

HEADS UP: The pinout for the runout sensor is BACKWARDS. The middle most pin is indeed ground - but the leftmost pin (closest to the screw terminals) is signal, and the right most is 3V3. This is easy to test. If you use female-to-male dupoint jumper extensions or other appropriate wire, it can easily seen that connecting the right most pin to the middle pin (confirmed to be ground) RESTARTS THE PRINTER. Connecting the left most pin to the middle pin toggles the state of the switch. This is important because if you're using a different kind of switch and want to wire it correctly / with only two wires, using the included diagram is absolutely useless since it's labeled incorrectly. The correct pinout is [signal, ground, 3v3] in that order!
