BIGTREETECH SKR Mini E3 V3.0 Control Board Integrated TMC2209 UART Stepper Driver Supports Marlin/Klipper Compatible Ender 3/Ender 3 Pro/Ender 3 V2 3D Printer Motherboard ZZB000590 Black

I installed the BIGTREETECH SKR Mini E3 V3.0 in my upgraded Ender 3 Pro, and it has been one of the best upgrades I’ve made to the printer. The form factor is perfect — it’s a true drop-in replacement for the stock Creality board, so it fits the existing case with no modifications. Installation was straightforward, connectors are clearly labelled, and documentation is decent enough that the whole swap was stress-free. Performance-wise, this board is excellent. The printer is noticeably quieter thanks to the TMC2209 stepper drivers, motion is smoother, and overall print quality has improved. It handles modern firmware like Marlin and Klipper very well, which makes it a great choice whether you’re just upgrading or planning future mods. Ease of use is another big plus. Everything worked as expected once installed, and setup was simple even with additional upgrades. It feels like a properly thought-out board rather than a budget compromise. Considering the features, quality, and performance you get, this is outstanding value for money. It transforms the Ender 3 into a far more capable and refined machine for a very reasonable cost. If you’re looking for a reliable, quiet, and powerful mainboard upgrade, I wouldn’t hesitate to recommend the SKR Mini E3 V3.0.

I recently upgraded my Ender 3 Pro with the BIGTREETECH SKR Mini E3 V3.0 Control Board, and the difference has been remarkable. This board is a direct replacement for the stock Creality board, making installation straightforward. With the pre-installed firmware, I was up and running in no time. The standout feature is the silent stepper drivers—my printer is now whisper-quiet compared to the stock board. No more loud motor noise, just smooth, precise movements. Print quality has also improved, with noticeably fewer artifacts and better control over retractions. Another great feature is the 32-bit processing power. Compared to the stock 8-bit board, everything runs smoother, from faster calculations to better handling of complex prints. It also supports Marlin 2.0, giving me access to advanced features like linear advance and thermal runaway protection for added safety. For anyone looking to upgrade their Ender 3 (or similar printers) with a silent, powerful, and reliable mainboard, the SKR Mini E3 is an absolute must-have. Highly recommended.

I love BTT boards for upgrading my 3d printers, they have a solid feature set, decent stepper drivers, are nice and quiet , and for me have been very reliable over the years. Picked up the V3 mini to go in an ender 5 pro so that I can add dual Z axis, but there are a few issues (which can all be worked around) you should be aware of. Firstly and the biggest issue, is that if you want to use a BL or CR touch for Z homing, the 5 pin header on the board DOES NOT WORK when using all 5 pins. Neither the precompiled BTT firmware provided by BTT themselves on GitHub or compiling yourself using the latest Marlin will work - the probe won't stop the bed crashing into the hotend. The only way around this is to recrimp the wires on your BL Touch to be a 3pin + 2pin JST, and plug the 3pin into the 5pin BL Touch header on the board, and plug the 2pin (black & white cables) into the Z endstop header. Z homing will then work perfectly. I spent hours trouble shooting this, it's been reported on GitHub as an open issue, it simply doesn't work using only the 5pin Secondly when using an ender printer the hotend fan isn't terminated in a JST 2pin header, as the stock board has a dedicated terminal for directly wiring it up. This isn't present on the V3 mini, so you will have to crimp your own header to allow plugging into the fan headers. Also from a Marlin standpoint, BTT haven't provided ANY settings for people that want to compile their own firmware, and haven't provided any fresh firmwares based on the latest Marlin releases - the most recent release is over a year old. It's also not yet officially supported by Marlin with their example configs in the stable release channel, although there are some configs in the current nightly builds - these aren't flawless however and I've still had to tweak them to get everything working nicely. It'd be a lot easier if BTT would open source what changes/settings are needed for Marlin, rather than only providing precompiled firmware. Also as mentioned above their BL Touch firmwares for Z safe homing DO NOT WORK, your bed WILL smash into the hotend.

Cette carte mère remplace définitivement, et sans regrets aucun, mon ancienne carte mère 8 bits d'origine sur mon imprimante Ender 3 PRO. Conçue pour la remplacer parfaitement, aussi bien au niveau de la disposition des connecteurs que des trous de fixation (d'ou son suffixe E3...), celle-ci apporte un lot de nouveautés et d'améliorations très sensibles. Déjà, la gestion des moteurs pas à pas TMC2209 avec les pilotes fournis est différente, et l'imprimante est devenue RÉELLEMENT silencieuse à ce niveau, c'est vraiment impressionnant. Lors d'une impression, seuls les ventilateurs se font désormais entendre... Et encore... Au démarrage, ceux-ci, gérés en mode PWM par cette carte, sont sur arrêt tant qu'il n'y a pas de besoin. On sent également que les moteurs sont quand même bien moins secoués, c'est beaucoup plus soft et sans à-coup ce qui devrait les préserver beaucoup plus, et la qualité des impressions va de pair. Ensuite, elle intègre plusieurs ports supplémentaires : port pour le détecteur de filament, coupure de l'alimentation, BL-Touch, écran LCD d'origine et/ou TFT (le très bon écran TFT35 E3 v3.0.1 de la même marque par exemple...), et même un port pour y connecter un ruban LED RGB. Le port USB mini passe au format USB micro, plus pratique... La gestion 32 bits permet également d'avoir une mémoire interne largement suffisante pour y loger tout les firmwares que vous voulez. BigTreeTech fournit sur son github des firmware Marlin ou Klipper prêt à l'emploi, mais rien ne vous empêche de compiler votre propre firmware personnalisé, ce que j'ai fait à partir de la dernière version stable de Marlin en V2.1.2.1 et ça marche parfaitement, avec les dernières fonctions à jour une fois activées (nivellement UBL, Z-probe Wizard, etc...). Elle intègre également une mémoire EEPROM (permanente) pour y stocker tout vos paramètres une fois définis. Bref, il ne lui manque rien par rapport à d'autre cartes, et mon imprimante va pouvoir reprendre quelques années de service sans trop de soucis...

Amazingky silent motors of my Ender 3 Pro

Comprata per sostituire la vecchia scheda V1.1.3 della mia Ender 3, dato che era arrivata a fine vita, ho preso questa Skr mini E3 V3.0 e le differenze si sono notate già da subito, qualità di fabbricazione molto buona, ultra silenziosa, si sentono solo le ventole quando è in funzione, le uniche 2 pecche sono la mancanza di un foglietto illustrativo dei collegamenti , e la seconda porta per l'asse Z, che purtroppo condivide lo stesso Driver della porta pricipale, per il resto super consigliata P.S se dovete montare il Bltouch o il CR Touch ufficiali Creality, il firmware che trovate sul Github con scritto Bltouch non va bene, perchè non è stata configurata la porta esatta, quindi dovete abilitarlo su Marlin attivando solo la porta Bltouch, senza specificare il pin "#define BL TOUCH", e funzionerà quella di default che sarebbe la porta adibita al bltouch come su scheda Creality 4.2.7

Mein Creality v4.2.2 Board hat ein Problem mit dem E-Stepper. Ich wollte es durch ein v4.2.7 ersetzen. In den Rezensionen dazu hatte ich von Qualitätsproblemen gelesen und mich - entsprechend einer der dortigen Empfehlungen - zu BTT umentschieden. Im Nachhinein eine ausgezeichnete Entscheidung. Das BTT passt perfekt und mit den TMC2209 läuft der Drucker jetzt super leise. Die Verarbeitung ist erstklassig - kein Vergleich zu meinem v4.2.2, das erhebliche Qualitätsmängel aufweist (beim/nach dem Ausbau gesehen). Falls ich nochmal ein Board kaufen müsste - auf jeden Fall wieder BTT. Da es in den Rezensionen negative Aussagen wegen bereits geöffneter Verpackungen gibt. Meine Verpackung war ebenfalls "geöffnet", ABER: * der Karton enthält keine Spur von einem Kebestreifen/Klebepad etc. - möglicherweise klebt BTT einfach nicht zu * die antistatische Folientüte - in der das Board war - zeigt keine Spur von Aufschneiden/Aufreißen, die Einkerbungen zum Aufreißen sind noch da - möglicherweise schweißt BTT die einfach nicht zu * Ich gehe also davon aus, das mein Board keine Retourenware war! Ein paar Tipps zur Installation und Firmware: * Anschluss der Lüfter - hier musste ich einmal umstecken, weil "Part Cooling" und "Enclosure Fan" in manchen Beschreibungen vertauscht sind * die von BTT bereitgestellte Firmware mit BL-Touch Unterstützung hat den selben nicht erkannt -> da kein Z-Endstop Schalter angeschlossen war hat sich die Nozzle beim Homing ins Bett gebohrt * sofort funktioniert hat hingegen die Firmware von "Seelenkind" (Seelenkind/BIGTREETECH-SKR-mini-E3 auf GitHub) * letzendlich habe ich mir die Marlin-Firmware dann selber gebaut (geht ganz einfach), um noch ein paar mehr Parameter meinen Wünschen anzupassen Mein Setup: * Ender-3 Pro * CR-Touch * Direct-Extruder (UniTak3D Ender 3 Direct Drive Upgrade-Kit mit Redrex Dual Gear Extruder)

It works great and made my original CR-10 very silent and smooth printing
