SKR Mini E3 - The best Ender 3 upgrade from stock?

[@shockwaves59]

ohh my god... so i jumped the gun thanks to your video, you are NOT KIDDING about with the noise difference, i actually giggled like a school girl, i cant get over how quiet it is...!

[@mdurbs5361]

The ONLY reason I am pondering making this upgrade is because my printer is working so absolutely brilliantly as a result of all the other changes I have made from Michael's Videos I just don't want to go one tiny step backwards. Literally from the test cube I have from my first print, to now is night and day different. My latest cube almost resembles an injection molded model!! You are changing the game Michael, please keep them coming. (I will undoubtedly do more).

[@TeachingTech]

Thanks buddy that is extremely kind. Glad to hear your printer is doing so well.

[@mdurbs5361]

Teaching Tech question whilst I have you.... any chance you can share your test print ‘X’ looked for something similar on thingiverse but couldn’t find anything. Assume I could make something easy but if you’re willing to share, thought I’d ask.

[@nightfallbob]

Thanks Michael, I was going to buy the SKR 1.3 but kept putting it off. Now thanks to your video I have just ordered the E3 board. Your channel is an asset to our community. Cheers mate

[@kylek29]

Curious if you'll get it soon .. the AliExpress store (official BigTree) just updated that they're having supply issues with the 2209 and won't ship until mid-October.

Received mine today 9th Oct,

[@sswbarnard]

Just received mine, a v1.2 board. Only 2 weeks from order to delivery in UK. I followed your instructions and was up and working inside of 30 mins. I'm really enjoying the near silence and so far print quality seems noticeably better. Really great instructional video (like all of your content), thanks very much Michael.

[@havoc010101]

Michael, Thanks a million. I assembled my Ender 3 and was up and running in a matter of hours thanks to your videos. I think that the SRK mini 1.3 will be the next upgrade as it solves all the issues that I intended to fix on my 3d printer. One of the features that I liked about the SRK mini was the addition of the BL Touch without the need to cut wires. Great video. Keep the content coming! -Michael

[@oleksandrpanforov2203]

First of all - thank you so much! Recommendation and tutorial are great. This is literally the best upgrade I've done to my Ender3. I've installed SKR 1.3 alongside with Noctua fans, and boom - it's now so quiet, I could print in the bedroom at night if I wanted to.

[@Shaennamun]

So let's talk about the duck. It's actually a programmer's friend. Whenever you're trying to fix a bug and can't seem to find the problem, you talk it out to the duck. If it's a difficult or persistent issue, you gather a council of ducks to work on the problem. Since talking out the issue often helps, and a rubber ducky will never get horribly confused or bored, this little ducky can be your helper friend. If all else fails, you have something squishy to hurl across the room.

[@AL8INOCARE8EAR]

II just outfitted my printer with this board and I cannot believe how much quieter it has made the motors. I was a little skeptical but very willing to make the printer quieter, as its set up in my bedroom, and I could not be happier about the result! Thank you SO much for this guide.

[@Cklauber]

You got the sub when I saw the Ayrton Senna jacket! This tutorial is awesome!

[@Justin-C]

Ordered shortly after this video was posted. Just got my board today & finished installing it. HOLY CRAP! Virtually zero stepper motor noise!! *Very* satisfying, if a bit unusual after hearing stepper motor noise for dozens and dozens of hours. Easy swap, came with Marlin 2.0 bugfix right out of the box, prints perfectly with no tweaks. Looking forward to trying linear advance and some of the other things I couldn't previously use.

[@georgemccann3886]

DONT GET CAUGHT OUT LIKE ME For anyone that has JUST revieced the v1.2 E3 MINI board and are trying to get your bltouch working on the default firmware but follow teaching tech's excellent video, Although Michael mentions about reversing the ground and +5v pins/ the UPDATED board is wired entierly different on the SERVO port i.e Gnd,+5V,PA1

[@mylesc2688]

Did you get the bltouch to work? After many hours of trying and reading commits for marlin 2.0 it seems like there is an bug in the code as they have changed the way auto bed levelling works. My machine doesn’t calculates the probe area correctly and goes off the build plate. If you have any tips I would be greatly appreciative. Cheers

[@mylesc2688]

Also this comment should be pinned as my pins were different like you said

[@georgemccann3886]

Myles C ensure you’re using the dedicated firmware from big tree’s github page for the 1.2v only, all the bed settings are correct within the version of marlin so shouldn’t need to play around too much although by default it’s a 7x7 grid for bl touch , don’t be shy to read the config file for marlin there is soo many new cool features and most of settings have an explanation about the settings above them

[@mylesc2688]

George McCann yeah I did use their version first but I think it’s in a recent update that might be causing an issue. My bltouch works fine it’s just the bed levelling. I have gone through every line of the config and read all the documentation I could find. The issue seems to be with the probe locations which is based on the new probe offset syntax NOZZLE_TO_PROBE_OFFSET. Is your version using that?

[@georgemccann3886]

Myles C I cannot even find that setting within config or config_adv If you’d like I can copy my entire config settings and put them in a text file for you?

[@chrisryan5052]

First off, thanks. Awesome tutorial. Second, not sure if anyone else had the same experience as I did but in performing the board swap-over just now, every single one of my connections on the original Creality board were hot glued into place. Took way longer than 15min... but works like a dream now.

[@hapihap8888]

you are the best dude, ty so much for all the hard work you do. my ender 3 experience would not be the same without you!

[@havoc010101]

Michael just installed the SKR MINI E3 v.1.2 mainboard and I must agree that in terms of the noise level over the stock stepper motor drivers is night and day! When homing or printing, the stepper motors bearly make any noise at all! Now if I could just find a more quiet mainboard cooling fan and hot end cooling fan I would be in business! Definitely worth the money! Great video, keep the content coming!

[@luciomachado6727]

I received my Mini E3 two days ago and even before I had time to try to install it you posted this video. Thank you very much!!! It will be much easier now.

[@xXxDJDANxXx1]

Thank you SO Much Michael. I've just recently purchased a SKR Mini E3 V1.2 Board as i was recommended to buy it over the upgraded Creality 1.1.5 Silent Board and just Wow. I'm so happy that I'm now able to use my Bltouch and My old Z end stop as a filament run out sensor both at the same time thanks to your excellent programming of the firmware and the fact that this board has a 32 bit processor and loads more space than the creality one. thank you once again for all the time your have taken to get this right for the people who with use it and thank you for releasing your version of the BTT Firmware Pre Compiled it has really helped me get off to an amazing start with this new board. KUDOS to you my friend and well deserved at that. keep up the excellent work because you don't get enough credit for what you are doing

[@Skeptic2006]

[@TomaszStachewicz]

thank you for your videos. thanks to them i took a dive, ordered skr mini, put it in my ender 3 in place of stock mainboard, using your wiring diagrams, and everything works perfectly from the get-go. this is my first 3d printer and without your videos i'd probably keep being afraid of upgrading.

[@Iboo30]

Awesome, thanks man! I just ordered my Ender 3 last week after the engineering company I was at bought one. Me and the coworker in the design department spent around two weeks playing around with it. I also watched most of your videos regarding it in addition to the other major 3d printing youtubers so I think I´m set and confident. This is a really cool addition that saves me a lot of trouble, I´m lucky I saw it.

[@spartan3299]

I installed the SKR Mini E3 1.2 into my E3 Pro. Works ok. Needs tuning and needs a new Marlin build that includes Mesh manual bed leveling. Now trying to learn VS code and platform IO without success so far. But I am new to all this. Thanks for all the great content!

[@TeachingTech]

Some FAQs from the comments: 1. -There are notes in the github about having to emulate EEPROM for this board with a file on the SD card. When compiling from Marlin 2.0, I only uncommented auto init eeprom and it worked without any problems. It made it's own EEPROM.DAT file on the sd card. EEPROM is verified working for me. Only downside is having to have the SD card in when you boot or try to save settings.- UPDATE: Thanks to my Patron Glen Roe for keeping me up to date. Marlin 2.0 has now been patched to avoid the need for the EEPROM data to be stored on the SD card. All of the downloads above been updated. 2. There are a few spare pins free for things like filament runout sensor, plus dedicated ports for RGB LED. It also support the new BIQU TFT24 touch screen. I plan to make a follow up covering these. 3. This board connects like usual to Octoprint or PC via USB. 4. If you've already upgraded to the SKR V1.3, don't despair! It's a more powerful board with more extend-ability. Only real downside is needing to print new case to fit it. 5. I purchased the Senna hoodie at the Aus GP this year. I'm sorry but I don't have an online link :)

Bought this board along with a BLTouch as my first hardware-related upgrades to my printer. The diagrams were very useful for the swap, I appreciate it

[@axelhopfinger533]

Definitely puts the Creality upgrade board to shame. By far the better value offer.

[@Arek_R.]

I know right? When I saw that they charge you over $50 just for stepper motor IC upgrade I immediatelly ignored it. They should sell it without trying to make a profit, they already made a profit on the sale of the printer.

[@axelhopfinger533]

@@Arek_R. No, they can make a profit. Just a reasonable one, in relation to the price of the printer. The Creality products just offer too little value and features for the price compared to the competition. Like, when they try to sell some bog standard cheap spatulas as "special print removal tools" for over $30 for a set of 3. Sure, quality is an important factor, but in the end, it's all made in China.

[@CYellowan]

Dude, i love that TT in the back. I got a bag of 100 RGB leds, lots of solder, wires, heatshrink, a 3D printer and plenty of filament. It's a HARD must to make my own like that from scratch with my own logo. Hell i even got a nano board and a spare chip so i can probably make a wave-program for the leds. Being a maker with printers is sick, thanks for the info and being inspiring. That goes to all these informative printer channels too!

[@bigmoike2833]

I'm having the same issue but cant find the latest fix for it :-( I'm technically challenged when it comes to editing marlin.. would someone have a firmware.bin for the v1.2 board? Or can someone confirm if the firmware.bin file that Michael has works without losing any new features?

[@Clubman-gt]

BigMoike01 hi just just go to the github skr mini e3 page and download the firmware v1.2 put it on your sd card and power cycle the printer hope this helps

Ahh.. ok.. I actually just downloaded that an pit it on the sd card... the the auto home fix is in that bin file?

[@bigmoike2833]

Humm, how do you know that the firmware has updated? I rebooted the E3 and the screen was blue, so I am assuming that it was loading... I have waited a bit now, but screen is still blue.. wondering if I now have to power down, remove sd card and power up??

BigMoike01 not sure? It’s about 10 seconds to load the firmware double check you got firmware for v1.2 board

Thanks Michael. Great video! I've learned a lot watching your videos along with others. I've had my Ender 3 for over a year now and have made many upgrades. When I found this video I had a SKR E3 DIP on the way with tmc2208 setup for UART. I was wondering if you're planning on doing a video about the DIP board with UART setup. If so, great. If not, I'm sure I'll be able to get it setup without much trouble. Thanks.

[@damienmartinguillerez]

Hi, Thanks for a great summary video of that board. It will help a lot people to get started with what I also consider the best board for the Ender 3. Your video however show the mini ups as an extension available for this board but this mini ups deliver 12v and the ender 3 is 24v.

[@TeachingTech]

I have them sitting here but haven't looked into them yet. I'll probably make a video on them at some stage.

[@damienmartinguillerez]

@@TeachingTech I do have one. It works fine for 12v but I cannot see how it can work with a 24v system. When charging them with 24v it might not blow (each caps is protected and unless you go over the fuse, the ups should be fine. Unless one of the component is rated for 24v max). There are voltage regulator around the circuit that will force the voltage to be max 2.5v x 5 = 12.5v. If I have not made oversight, this will force the voltage of the PSU to output 12v or will take a lot of heat in a single resistance. I would not test it on a 24v system. Best case the thing works but suddenly your motor gets half the voltage so needs twice the power and start heating. It's 0 risk for the printer but the charge wont be enough to park the head and save everything before proper shutdown. Anyway this sounds like an interesting experiment to drive if you wish to know what happens used on a 24v system. Just be prepared for the ups to smoke. If I am wrong with the voltage regulator behavior, then the supercaps will explore and the gas of caps are pretty nasty. Anyway I'll be really interested to see an actual test if you are willing to take the chance ;)

MKS Gen L is still a good mainboard!

[@oleurgast730]

If you have an Gen L, you might upgrade to an SKR 1.3 which has same formfactor. It has a CPU with EEPROM, so no need to emulate it on SD as on the STM32 boards. As you already have the stepper drivers, going 32bit is less than 20$. Also on SKR 1.3 you can use smoothieware.

[@CS-PROD-i3s]

@@oleurgast730 I Think I'm going to have to try the SKR 1.3 because for the life of me I cannot get the GEN L to work. I might have fried it. It accepts firmware but it does nothing and my MKS touchscreen does nothing. The temps show 0 across the board. The touchscreen is working but the buttons do nothing...

[@SmallSpoonBrigade]

The sound level difference alone was sufficient to warrant me buying that bad boy. My E3 isn't particularly loud to begin with, but if you're getting that kind of a reduction, it means that I can definitely use it at times when the neighbors want quiet. The other stuff is just bonuses. And BTW, when I bought the ABL from Creality, it came with the necessary gear to update the firmware.

[@shockwaves59]

i have to say im not all that impressed with the Screen they do, its literally plug and play in to the TFT marked headers , no firmware changes or anything which is great for ease of use, but theres a few problems ive had which ill get in to later... from what i understand (forgive me if i get this wrong then feel free to correct me) it seems to piggy back on the serial connection as if it was plugged in to the USB port. here lies my first conflicts with the screen and octoprint which again ill get in to soon. if you've used octoprint (who dosent..?) you know the annoyance of trying to cancel a print or change temperature while its pre-heating, either you wait a few mins depending on your material and temperatures or you switch it of at the plug and back on if your home/by it. if you try and change the temperature while its heating up you cant! you have to wait till its finished heating up before you change or use the STOCK LCD with your printer. so.. same deal, the printer sends the same busy commands too the TFT locking it out of any changes at all until its finished heating, of coruce you can use the m108/EMERGENCY_PARSER commands with octoprint but the e3 mini firmware screams at me if i try and enable this saying its not supported yet, and there dosent seem to be a easy way of adding these to the TFT firmware Evan if i had it enabled, but i could be wrong.. another annoying thing i've bumped in to twice now in my few weeks of owner ship is that because the TFT seems to share the same serial as octoprint, i've had octoprint error out of my a few times just disconnecting saying something along the lines of "timeout" "too many connections" again not exactly what is said but my memory is shot today hah, and the layout is kinda boring and poor for a COLOR screen now don't get me wrong its very handy for changing a temperature quickly if you want to do some testing before a print or to change it AFTER heat up, but for the time in between when you think "oh crap wrong temperature" you find your self having to use the stock screen, so then your left with using both, probably not the upgrade solution others and me included was expecting so to summarize seems to share this serial connection the screen also has the same limitations seems to conflict with octoprint causing disconnects and then failed/unfinished prints poor layout and use of a color screen and i am i no way trying to say its crap, as the main board it bloody amazing, but the screen.. eh.. i dunno id stay away from it, maybe instead get your self a screen for your PI and set up touch UI for octoprint, and have a much better UI experience and hopefully no serial conflicts, i mean you probably have your pi right next to the printer anyway right?.. i think that's the route i'm going to take next..

[@SmallSpoonBrigade]

Probably not worth it, the board is a literal nightmare to install due to the lack of documentation and photos. The support staff seem helpful, but for something that's allegedly plug and play, it's way too hard to get working. Having proper photos of the board with the relevant wires rather than a wiring diagram would go miles towards making the process real. As would having real documentation about how the firmware is supposed to work, including video of the procedure as it's far more difficult than just loading the firmware onto an SD card and powering on the machine.

Thanks for the info on the SKR mini E3. I just built my Ender 3, and the board that came with it had a bad Z axis driver. So there is a SKR mini E3 on the way.

[@YpsilonTM]

I've only had problems with this board, BLtouch has so many problems with this board.

[@TeachingTech]

Did you connect it as shown or with the 'probe' port?

[@YpsilonTM]

@@TeachingTech Yes, it's connected to the Z-Stop Im on marlin 2.0-Bugfix. It's a V3.0 BLtouch and I've read so far alot of people have this problem with the board. And when they switch to the original Creality board the BLtouch works just fine. This is a video of the problem we are all having (i.imgur.com/BEdxRFO.mp4) So while probing it randomly fails, you see the BLtouch led becoming red but the trigger is not registerd by the board.

[@boggisthecat]

Ypsilon Media Designs That looks like a firmware problem, but could be a marginal signal. Is it only the BLTouch version 3 affected? If so, perhaps the hardware fix for the original Melzi boards would work?

[@Cloudman572]

@@TeachingTech Reddit has lots of problem comments about the mini and the DIP boards including dead drivers and BL touch sending nozzle into bed or model.

[@originaltrilogy1]

@@YpsilonTM Interesting, I have been running this board and a BL-Touch version 3 and haven't had that problem.

[@Mr_Gadge]

V1.2 is in! :) one week for delivery in UK. Just installed. EDIT: All sorted. Did loads of pids, rock solid now, under 0.5 degree variance. I've never used bl touch but would like to, just dunno about all this wiring malarkey. Gonna look into both as I don't mind a marlin fiddle.

[@videogame1291]

Next you need to do a tutorial for installing auto-leveling sensors on the mini E3

[@luciomachado6727]

I just installed the SKR Mini E3. It was very easy. I didn't have to flash a new firmware, everything worked well. I think it solved all the surface artifacts and apparently my Ender 3 prints as well as the Ender 2 now. I still have to check with a grey or black filament to be sure.

[@GilDev2]

Great! Was looking for this video to be made! :-)

[@Crazyates11]

I was looking at the SKR 1.3 and a set of 2209, but for this price/convenience, I think I'll do this. Thanks so much!

[@oleurgast730]

You might prefer the SKR 1.3 as it has an other CPU. The SKR 1.3 can be used with smoothieware, which is more advanced than marlin 2.0.x. Marlin 2.0.x is alpha. Until 07-30-19 even the HAL for the STM32 was defect, as soon as you went aside from stock configuration, strange things happened (like activating the probe input to use a simple film probe or a piezo, all endstops where deactivated). The CPU on the SKR1.3 is much better supported, as its the same as on smoothieboard - the STM32F1-series is relative new for 3d-controllboards. Also the STM32F1... have no EEPROM. Marlin emulates EEPROM on Micro-SD. Can give some trouble if changing the SD-Card...

[@thisiskeithb]

Just be mindful of the center mounting hole on the E3 boards. It’s dangerously close to a resistor that can be crushed by a screw head, so it’s best to leave that screw out.

[@TeachingTech]

Great tip, thanks Keith. Thanks for all your work with Marlin too!

[@Sharft6]

I think this mod is quite a long way from being the best. 1. stock 4.2.2 and 4.2.7 boards dont need a bootloader either. or already have it integrated? 2. easy enough to update marlin with thermal runaway protection etc on the stock board. 3. stock 4.2.2 and 4.2.7 is also 32bit 4. manual bed leveling is easy and cheap/free when you get the hang of it. 5. Only surface artifacts I see are caused by the infill showing through if the walls are too thin 6. Love the classic loud stepper sound 7. Not as easy or affordable as the stock board already in the machine I would say hands down the best upgrade I did was adding a bimetalic heat break and a hardened steel nozzle. Even cheaper than changing the board and it lets me print all kinds of filament. For the price though, you cant beat the cardboard box enclosure - another fantastic upgrade for the ender 3.

[@belkocik]

Ok, now I'm ready to install the skr mini e3 :D How to plug cables for Z end stop - black and white when there is the Z axis plug [installing bltouch]?

[@TeachingTech]

The diagram is in the video and linked in the description.

[@833psz]

When installing a BLTouch you remove and discard your Z end stop switch, it is no longer required as the BLTouch acts as your Z-axis end stop. You can remove the switch from the side of the printer and remove the old wire completely from the motherboard compartment.

[@TeachingTech]

I agree except I leave my microswitch in place for videos I make without ABL. Including the next one where the BLtouch is in the way..

Have you find an answer? Been busting around and can't find a clear how-to (at least for my understanding) on how to install it.

This will be on my list of future upgrades. I'm upgrading in stages. Today Octopi goes on. Next I will be updating firmware, whenever my UNO R3 ATmega328P Development Board gets here. I'll run like this for a few months at least before I try switching out the main board.

[@tal1296]

Waited for this video, I would not buy this unless you approve it :) Great video! Will you show how to add filament runout sensor and RGB LEDs?

[@DougSchieszer]

I just installed this board in your rear enclosure and wow, so far very impressive and I love how the printer looks with everything in the back. It is so quiet now I notice the fan noise so much more! One thing I did notice is that when installing the mini E3 in your enclosure my z stop wire is just barely long enough. in fact I had to bend the pins a little on the switch to ease some tension. I might see if I can buy a slightly longer cable or just simply cut and extend this one. Thanks for your enclosure design and your videos!

[@axelSixtySix]

Actually, the Cheetah is less expensive than any version of the SKR, and also carries on board trinamic drivers, yummy isn't it ? 😉

I looked into it but there seemed to be some persistent bugs. I'm sure they will get them sorted though.

Michael, can you point us toward which pins to put the runout sensor on. I guessing everything else will be the same as the stock BLT and runout setup. Thanks

[@Waltkat]

@@tinkeringwithelectronics Not sure if this is useful or not but the TFT35 V3.0 display has connections for a runout sensor. It also has a connection for machine power shut-down once a print is finished.

This is 3 months after MIchael's video released, after they waited for the 2209 drivers backordered.. and it still has the buggy firmware. highly recommend you download and install the new firmware... otherwise when you do your first print it will send the nozzle off the edge of the bed and make a loud grinding sound as the belts slip... i downloaded the firmware and it fixed it right away!!

[@marktosiello666]

Just got my Ender 3 Pro and a few accessories (upgrades), including this board. Your installation diagrams are great! Having built numerous computers, this board would have been only a few minutes to change, EXCEPT for the insane procedure that Creality appears to use in which they HOT GLUE all of the connectors in place. It took me almost 40 minutes to get all of the hot glue off to the point where I was confident I could pull the connectors without yanking the sockets off of the PCB. It's a good thing I wasn't saving the original board, because despite my best efforts, some small amount of hot glue remained on the hot end thermistor socket which was enough to cause the socket to pull partially out of the PCB as I was removing the connector. Who does this? Anyway, GREAT content and I'm learning TONS from you!

[@seventyfive1]

I considered the mini dip but just said YOLO and bought the full SKR v1.3 and some 2209's. Printed a case and I couldn't be happier. The full board gives you so many more options and the only drawback is you have to print a case which takes about 6 hours. Knowing what i know now, I really just don't know why someone would buy a mini. The whole point of having a 3D printer is to print stuff so why not just print a new motherboard case and get a full board?

For real?- " I really just don't know why someone would buy a mini" Because it is cheaper and more convenient.
