🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

The BTT Mini E3 V3 Mainboard is generally appreciated for its high quality and significant contributions to upgrading 3D printers, making them quieter and faster. One unexpected perk enjoyed by users is a small rubber duck included in the package, which is regarded as a fun and whimsical companion that seems to boost the printer's speed and accuracy. However, it appears that the mainboard is not a suitable choice for all models of 3D printers, especially the Ender 5 Plus, as it made the setup more complex and difficult.

Pros

  • 🦆 Comes with a fun and whimsical rubber duck that adds joy to the printing process.
  • 🤫 Has TMC 2209 drivers that make the printer very quiet.
  • 🔧 Offers potential for significant upgrades to printers.
  • 🔨 Provides ease of firmware update by just dropping a 'firmware.bin' file onto SD card and turning the printer on.

Cons

  • 🔌 Installation can be challenging, particularly if upgrading from a stock board that has components hot-glued.
  • 💡 Configuring the firmware for ABL with BLTouch can be tricky, due to lack of comprehensive instructions.
  • 🖨️ Not suitable for Ender 5 Plus and can cause complications.
  • 🔒 The board may require advanced skills to set up, as it is not exactly a plug and play.

Should I Buy It?

If you are a hobbyist or professional who is prepared for upgrading your 3D printer and are ready to leverage the mainboard's full potential, then this product is recommended. Keep in mind, though, that it might not be suitable for Ender 5 Plus and requires manual setup, thus it's not a plug-and-play solution. If you’re unsure about this, it might be good to stick with what you have, especially if it’s already serving you well.

Style: SKR Mini E3 V3.0+TFT35 E3 V3.0.1
Ok, I’ve had this board for over a year at this point, so I have a good bit of experience with it. I got it to try to run Klipper on my Ender Extender 400XL (can’t call it an Ender 3 anymore), which it failed with Klipper (my pi won’t connect for some reason), but it runs Marlin just fine. I see the reviews saying that it isn’t that quiet, but mine is whisper quiet compared to my old 4.2.2 Creality board, the filament coming off the 5kg spool is louder than the actual printer. There is still some noise from the steppers and the belts, but that’s pretty normal. Aside from the Klipper fail, this board has run flawlessly, only reason it’s not getting a 5 star is that Klipper issue I had, but even with that issue, there is a ton of adjustability in the menus: acceleration, stepper current, etc ... show more

    • One Small (?) QA Issue
Style: SKR Pico V1.0
Seems like a good board. Only noticed one small (?) QA issue so far: the hole spacing on the motor driver heatsink apparently does not match the hole spacing on the PCB. To make it work, Bigtreetech installed the fasteners at a weird angle that is putting a bunch of stress on the PCB. Guess only time will tell if it will destroy the board/ cause a fire etc. ... show more

    • The BEST upgrade for Ender 3 Pro
This mainboard was by far the best upgrade to my Ender 3 Pro (MicroSwiss all-metal hotend is a close second). The TMC 2209 drivers make the steppers so quiet that I sometimes forget it is actually doing something (although there is the fan noise). The added space on the EEPROM was perfect for fitting all the features I wanted into my Marlin build (Linear Advance, Auto-Bed leveling, and Junction Deviation in particular). Not entirely sure why BIGTREETECH only lists 256KB...it is actually 512KB which allows me to compile 'bloaty' stuff (PIDBEDTEMP, M503, boot images, extra menu items for LCD, etc.) into the firmware and not have to worry about saving every last little byte. Installation wasn't difficult, but it was frustrating as Creality hot-glued everything to their stock board. Took a long time to get that stuff off without damaging anything. Came pre-loaded with a recent version of Marlin and was easy to flash to a custom build by simply dropping a 'firmeware.bin' file onto SD card and turning the printer on. A nice feature is that after it updates the firmware, it renames the file to 'firmware.cur' so it does not try to reflash every time you turn the printer on (the bootloader I flashed to my stock board didn't do this). BLTouch & Auto-Bed Leveling I did have some trouble configuring the firmware for ABL using the BLTouch at first. Most guides out there assume you are plugging into the Z-Stop on the board, but this board has the 5-pin header for BLTouch (which was convenient to build a 5-pin DuPont connector right to the board instead of separate 3-pin and 2-pin connectors). In your configuration.h, make sure that #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN is commented out and that you are using #define USE_PROBE_FOR_Z_HOMING. One other thing I had to change was #define Z_MIN_PROBE_PIN PC14. PC14 is the Z-endstop pin from the 5-pin header. The pin set to this by default will not work. In configuration_adv.h, PROBE_OFFSET_WIZARD is a really handy menu option to help set the z-probe offset value. There are other minor things you have to change to get ABL to work, but all the guides out there cover that in great detail. The Instruction Manual does include a link to pre-compiled Marlin binaries for this board. I believe from that page the 'firmware-bltouch.bin' would have worked for me using the 5-pin Z-Probe header, however the webpage is unclear and I wanted more control over what features were in my firmware. Would be nice if they supplied the configuration.h and configuration_adv.h files for these builds so that users know what's in them. Extra Stuff I bought the kit with the Mainboard, BLTouch and no touchscreen display. Be aware that the wires for the BLTouch probe are nowhere near long enough to reach your mainboard. You WILL have to do custom wiring or need to buy a BLTouch extension cable (1-meter should be long enough). This kit does NOT come with a bracket for the BLTouch either. I printed one out from Thingiverse and it works great, but if you prefer a metal bracket, you'll have to buy it separate from this. The kit does have appropriate screws/washers/springs to install the BLTouch. It is pretty clear in the description and pictures that it would not come with the bracket or long-enough cabling, however some folks might not notice or realize they need these things and be very disappointed. Overall a great board and an awesome upgrade that would really only be better if the documentation was more specific instead of a few pictures and incoherent sentences. In particular, configuring Marlin for BLTouch using this board's 5-pin header (notably the PC14 pin). Oddly, the BIGTREETECH configuration files specifically for this board on GitHub for Marlin do NOT have the pin defined as PC14. Despite a few challenges, this is still 5-stars all around because this upgrade is not designed for people who like for things to 'just work' or simple plug n' play. Go buy a more expensive printer if that is what you want. ... show more

    • Quack-tastic Delight: A Rubber Ducky Marvel in a Mainboard Box!
Style: SKR Mini E3 V2.0 (STM32F103RCT6)
Review Image by Harry bugger Harry bugger
Let me start by saying that I never knew a tiny rubber ducky could bring such joy to my life, let alone a mainboard purchase! If you're wondering how this review ended up focusing on a rubber ducky rather than the actual product, you're in for a treat (or should I say, a quack). So there I was, eagerly unboxing my brand-new BTT Mini E3 V3 Mainboard, ready to dive into the world of 3D printing marvels. And what do I find nestled inside the packaging? An unexpected surprise, in the form of a pint-sized rubber ducky. What in the world was this little fella doing here? I couldn't help but chuckle at the audacity of it all. At first, I thought, "Okay, this must be some sort of secret debugging tool for advanced users." But alas, it was just a rubber ducky in all its unassuming glory. Well played, BTT, well played. Who knew that alongside high-tech components, what my 3D printing adventures were truly missing was a whimsical companion? This adorable, quacking sidekick has since become an indispensable part of my creative process. Every time I power up my printer, I can't help but place this mini ducky next to it, watching over me with its beady little eyes, as if to say, "Let's make some quack-tacular masterpieces together!" It's not just the quirkiness that won me over. This rubber ducky is also an absolute wizard at troubleshooting. Whenever I encounter a printing hiccup or a stubborn clog, I turn to my newfound feathered friend for guidance. It's amazing how a simple squeak from the ducky can seemingly unlock the mysteries of the universe and make my prints magically succeed. I've even noticed some hidden superpowers this ducky possesses. Its mere presence seems to boost the printer's speed and accuracy. Seriously, this ducky is like the Flash of the 3D printing world. I'm half-expecting it to sprout wings and zoom around the room, ensuring perfect layer adhesion and infill density. In conclusion, the BTT Mini E3 V3 Mainboard is top-notch, but let's be honest, it's the rubber ducky that steals the show. It might seem like a minor detail, but trust me, this quacking critter is a game-changer. So if you're in the market for an excellent mainboard with a bonus companion that brings joy, humor, and unexpected troubleshooting prowess, look no further. Prepare to enter a world where technology meets whimsy, and 3D printing becomes a delightful quacky adventure! Five stars, not for the mainboard itself, but for the rubber ducky that has revolutionized my printing experience. Bravo, BTT, bravo! Quack on, my fellow 3D printing enthusiasts! ... show more

    • Buy parts separately don't buy kit
Style: SKR Mini E3 V3.0+TFT35 E3 V3.0.1
TFT35 screen was trouble from the start. Reflashed firmware did no good. Main board is fine. Everything works with old screen installed. In order to get a new screen, I have to return everything. I'm not taking the main board out again. So, buy the parts separately, not in a kit like this. Update: The seller sent me a new TFT35 screen and everything works now. Deducted one star for the hassle. I still stand by my recommendation to buy the parts separately vs. this kit. It took two weeks to get this resolved and would have been significantly less time and trouble if I could have replaced just the defective part. ... show more
