Authentic Creality 4.2.7 32 Bit TMC2225 Silent Control Board with Filament Runout Sensor, 24V Ultra Silent Fan for Ender 3 / Pro / V2 / 5 Includes 1M Capricorn PTFE and Other Accessories Upgrade Kit

Update 3/20/2021: The filament runout sensor uses a simple internal microswitch, and is unfortunately unable to accept a filament entering in reverse. This is a problem, because once the end of the filament triggers the sensor during normal prints and causes the printer to initiate the filament runout sequence, the subsequent filament unload process wont be able to push the remaining filament back through this sensor! The filament will get stuck inside the sensor resulting in the extruder clicking in reverse and its gears chewing filament in place. The design is really not great at all. A very very simple design tweak would have avoided the issue altogether (the internal lever should have been designed to have a hump shape instead of a cliff shape). Oh well, I guess for this price they could not be bothered to think through such corner cases. ----- Original Review: I can no longer hear the stepper motors at all after upgrading. I knew this was going to reduce some of the wee-waa noises during printing, but I was not expecting a difference quite this big. The only noise I now hear is coming from the fans, and I am working on strategies to make those quieter as well. I am really glad I went with this upgrade. A few things to know if you purchase this board: 1. the firmware that comes on the board is really old (1.x.x) and optimized for 8-bit ATmel processors. Its easier to download the latest firmware source code (2.x.x) and build it yourself with VSCode -- lots of videos online on how to do this easily. 2. Make sure you set the correct motherboard in Configuration.h (for example BOARD_CREALITY_V427) 3. Set the correct build target in platformio.ini (STM32F103RET6_creality). Good luck!!

Truth told, easy to install only gets a 4 rating because Creality saw fit to put the mainboard upside down in the housing, and its just a pain in the --- to get in there. The meat and potatoes of this one is, as an upgrade, it borders on essential. All the screaming the steppers did when my printer was new has been practically silenced with this board installed. Its also more capable than the stock board I had as far as installing a BL Touch sensor. (If you choose to install one of those - and you should - make sure your wiring is correct so you dont cook anything!) Worth the buy for sure, if only for the quiet operation. If youre a real modder, though, make sure you see if you arent interested in other makers boards. There are a LOT of expansion opportunities.

F1rst Layer has top notch support. I’ve basically upgraded my entire ender 3 pro through them. The only thing original here is the frame and power supply. They’re been there every step of the way to help with any questions I have

I added the sprite hotend to my Ender 3 Pro.Install was very straightforward and the addition of the silent fan helped quiet my setup. I mainly print props and figures and so far this hotend has not disappointed. This combined with the F1rstLayer firmware has helped me get great quality prints.

This direct drive extruder upgrade is a must have especially when paired with auto bed leveling and the silent board upgrade. This extruder is near dead silent when compared to the original hot end and is less prone to clogging and the better build quality and added thermal protection allows further ability to print in more exotic filaments and even more important allow higher print temps without having you hot end melt apart and cause a fire. If you haven’t upgraded your board or hot end please do the original build quality of the Ender 3 is sub par and has a few flaws that can be easily corrected within a few hours.

From whirring, buzzing, whistling and clicking to DEAD SILENCE - I mean you hear NOTHING AT ALL. Like a new father I was checking on my newborn constantly to see if it was still breathing kinda quiet. There are so many new features that are available as well. Print quality improved immensely and I am a total n00b to 3d printing. It was plug and play install on my Ender-3 - not a pro or V2. Install was easy and straight forward. The filament run out sensor stopped a print and waited for me to change out mid print and resumed exactly where it left off, Saved me 3 hours of reprint time the 3rd day after install. Only reason I put 4 stars on ease of install is the fans that came with it - the wires needed spliced and extended. YOU MUST INSTALL THIS IF YOU OWN A ENDER SERIES PRINTER - YOU WILL THANK ME!

Great product. Must get for ender 3 especially if you have multiple printers.

Wow I can’t believe the customer service they provide. I have a really old BLTouch that I thought wasn’t compatible to this board but I reached out and they walked me step by step almost immediately. The board really does what it says: quite AF prints! I can’t hear it at all it’s insane. Easy to install and easy to flash!

Easy install. Everything was plug and play. The XYZ axis motors are pretty much silent now. Definitely worth the buy.

Edit: The customer support team at F1rst Layer is First Class as they reached out to attempt to help me troubleshoot my issues. While they were not able to resolve my issues (I am going from an ender 3 to an ender 5) they were extremely detailed and attempted to provide many help articles and even offered for me to reach out and speak with them directly on Facebook for more support. The product itself works, it just didnt work for me. 6/10 product 4/10 installation support/guidance 10/10 Customer Support (Original Review Below) ======================================================== Black Screen of Death Control Screen Hot end Immediately Heated up after power was turned on Firmware update after firmware update after firmware update Bubbly Prints Jams The list of problems is Ongoing There is almost 0 support to be found online regarding these products, nor is there an agreed standard I only bought this kit because the factory hot end welded itself to the nozzle and I couldnt replace the nozzle without replacing the whole hot end. Hopefully I can return this, because honestly I shouldve just purchased a new Hot End and kept everything else the same. This Ruined my Ender 3 V2
