Big Tree Tech SKR Mini E3 V2.0 - Silent Main Board - Install - Chris's Basement

[@scotchman2571]

Best tutorial available anywhere. If you're having issues with getting your printer working, just get the hardware that you see in this video and follow along. Chris is going step-by-step which might seems unnecessary but if you're new to 3d printing it's very much appreciated. Keep up the good work Chris!

[@ChrisRiley]

Thanks!

I'm 74 years young and brand new to this, Chris has been a lifesaver! He does talk a little fast but I know how to back up and play it over again. My new BTT SKR is working great, now on to his other video on how to add a BL touch. Thank you very much Chris.

[@AverageNerdGuy]

Just put my SKR v2 in my Ender 3 Pro, The drivers are CRAZY SILENT with these step motors and it runs SOOOO much smoother and faster. I was super concerned about building a new firmware for my board but this tutorial was perfect and taught me a TON!!!! Such a great upgrade. Gonna put in my BLTouch tomorrow or sometime next week, I also have the FTF70 7" touchscreen to do but wanted to get this installed and the machine speed up so when I print the casing it doesnt take me forever and I get the best quality. For now this get the thing running flawlessly!! Thanks again.

[@BlueKaiTheEnd-]

Possibly the best video on the SKR Mini E3 V2. You get right to the point. Got this board last week and added this and the TFT35 V3 to the ender 5 plus. Got 2 very minor issues related to re configuring a pin for an extra fan and hotend trying to move beyond the the beds x/y bounds. Think this tackles the re configuration issue. Will give that a try later.

[@ChrisRiley]

Nice! Hopefully this will be helpful.

@@ChrisRiley This was a huge help in figuring how to edit the configs and compile everything. One thing I did different was in platformio.ini, I had to change default_envs to "STM32F103RC_btt_512K" instead of "STM32F103RE_btt".

Chris your explanation is outstanding. I'm waiting for my Ender 5 to arrive & ordered the SKR V2.0 board with it. I am a completely new to 3D printing this will be my first time & gotta say its a bit intimidating having to config things at this level. Watching most videos has left me a bit confused, esp since I have never used Github before & your style of explanation has given me way more confidence - much appreciation, well done!

[@ChrisRiley]

Thanks! Good luck with your projects!

[@jaytee60399]

Quick warning. Just did this exactly how Chris did it. Found out that the colors for the hot end thermistor and heated bed were swapped. To avoid any problems, do the following: 1. Once configured, set the heated bed to 50c and feel it for any temp change. 2. If it does not change in temp or it shows the temperature of the nozzle increasing, simply swap the connections and repeat. Don't just assume that the wiring is correct like I did. Made the mistake and my heated bed started increasing in temperature almost immediately. Error was given and had to swap the wires. Fixed the issue. Just wanted everyone to know.

Just ordered the board and touchscreen combo. This was the best video covering Marlin. I've done 1 Marlin config 32bit board before, but I needed a serious refresher. Lol I'll have to tweak my E steps, turn on Auto PID function because it's so handy, set bed size to 235x235, tweak BLtouch probe offset from nozzle, and that should be about it.

[@ChrisRiley]

Awesome, thank you!

[@stuartcrann]

Cheers Chris. If I'd actually seen the fan cover mod, I wouldn't even be doing this! The reason I bought the board was because I dropped a couple of nuts in the fan (Didn't realise that's where they'd gone) whilst doing a fan upgrade on the hot end. Said nuts fell through the fan and shorted the OEM board when I turned it on.

[@rambokd]

Chris, the fan pins you used for the hot end are setup for the MB fan, It’s is controlled by firmware but the reason it came on is during any movement by the steppers the MB fan comes on which was always on on the 1.2. My hot end fan is on all the time with the constant power setup...cheers as I got further in the video I saw you figured it..

I have an Ender 3, which I have had for a number of years. It is a great printer and has served me well so far. I have been running it with the stock Ender main board & using MatterControl, as I like the ability to send send files directly to the printer, from the computer and to be able to control the printer while it is operating.

OK Chris, fan question, fans are, case fan, hot end fan and part fan- on my OEM Ender 3 board i have stripped wires that go on teh screw terminal beside the main board power and my other 2 clipped on the board. i follower your video to set the fan in the code (FAN1_PIN) with the set value of 50 like you.. but can I still do that with putting my wires back in the screw terminal ( which you didn't ) as you have another setup, or should I splice the board connector to go on the hotend fan and then constant the case fan to the constant power... ugh

[@ChrisRiley]

So the fans got sorted?

[@PMcDFPV]

I do have a question though, what do you consider or what did I say to Max temps are for the hot end in the bed? And then what kind of increase can you get on that by breaking off the MOSFETs?

[@PMcDFPV]

What did it say* sorry I dictated that and should have checked first lol

[@ChrisRiley]

So it's really not about max temp as far as the board goes, the hotends, you see 50w heaters, about any mosfet will run it. Now beds, you can really only expect to get around 120c max on DC, and if it's over about 220x220 the load can get really high, above 11amp. That is where you need to look at the loads and consider moving that to an external mosfet. I would have to look up the chip numbers to tell you max load. A lot of us go to AC beds for this reason.

[@TuxWing]

Why did it look like your hot-end fan and heated bed terminals were wiggling as you were touching them with your screwdriver? That doesn't seem safe!

[@ChrisRiley]

Sometime those terminal aren't the sturdiest items.

You say Fan0 (PC6) in controlled by default?.... that is where the the original (creality) blue/yellow wires go, correct? I have no control over the part cooling fan when connected there. It stays on permanent and no control from the console either. With the v1.2 board it does control the part cool fan without any issues. It seems like I'm finding a lot out there with the same issue.

[@ChrisRiley]

Yes, fan 0 should be your controllable part fan, you have it correct. I guess it's a board issue. That is sad to hear.

[@Alegzander1990]

Hello Chris, i have a question. I've installed this board on a CR10-Mini. It was running an SKR 1.4 Turbo before (temporarily since i didn't want to cut up the control box for SD and USB), and it was fine, nothing weird going on. However i had a bunch of issues with the Mini E3. The steppers were receiving the wrong commands. For example X was behaving like Z both in terms of Hybrid Threshold and steps/mm, Z was behaving like either X or Y (couldn't quite tell) and Y seemed to behave like the extruder and got hot AF, even though they were all wired correctly. I didn't want to start from the Ender 3 config and change it for my machine, rather i started from the stock Creality config and changed it for this board. After a day of troubleshooting i found some settings in Marlin that would allow me to get them running proprely (X_SLAVE_ADDRESS 0, Y_SLAVE_ADDRESS 2, Z_SLAVE_ADDRESS 1, E0_SLAVE_ADDRESS 3) and the "best part" is i couldn't find anything regarding the issue on the internet. I still have one nagging issue though. My part cooling fans (i have 2 5015 in parallel and a Noctua 40x20 for the hotend heatsink on a Hero Me Gen5) are buzzing. Sounds like PWM noise, but it's really annoying and loud. Sounds almost like a small speaker. They seem to only buzz below 75%, or maybe it's just the fan noise that masks it at 75% and above, but it didn't seem like it, i tried listening carefully. I don't know about the heatsink fan since i always run that at 100% and it's basically dead silent. I had tried enabling FAST_PWM_FAN in Marlin (Configuration.h) since the description seemed to suggest i might fix my issue, however it doesn't seem to be supported for that chip yet. My question is, do you think this is a "bug" with the board, maybe related to the fact it's running 12v and not 24v (even though it can run in both and they also state it supports the CR10 Mini and original CR10 which are both 12v) or a config issue or a hardware issue on my side (fans or wiring) ? Have you installed it alongside a 12v PSU or encountered this issue with any of your machines ? Curious if maybe you know of a solution for this. Needless to say, neither of these issues presented themselves on the SKR 1.4 Turbo...

[@ChrisRiley]

I think it might be a bug on the board, I haven't tried these on 12v yet, but I can almost guess that it has something to do with the new regulator on the board they are using. Not sure what the fix would be.

[@crookedtooth6445]

I've had the exact same issues... I just fixed the steppers by comparing the configuration_adv.h with the official marlin branch with the broken one from BTT (the current BTT branch doesn't compile) and from there change stuff to copy the BTT branch. As for the PWM noise. I feel like it's hardware related and seeing that the only major change from V1.2 is the 5V regulator it would seem like a logical source... I run on 12V but it really shouldn't make a difference from running on 24V, if anything the datasheet says the regulator is more efficient at 12V. I think i'll check it out with an oscilloscope next friday and try to figure out were the noise is coming from.

[@ChrisRiley]

@@crookedtooth6445 Thanks for the the update, I would be interested to see what you find.

[@Alegzander1990]

@@crookedtooth6445 I'd also be very interested in your findings. I have long since fixed my steppers, infact they were already fixed when i had posted this. As for the fans, i used SOFT_PWM in Marlin and they're definetly quieter. No longer do i have the annoying electrical whining, however now i've got clicking noise when it pulses at low frequencies (i.e. when you're running the fan slowly)... Could probably tune it by messing with the scale, but it eats into the range of PWM that you can use from what i understood. Anyway, haven't touched the printer in a week or so since i've been very busy with work and other things as of late.

[@GoranMilici]

i dont know if anyone mentioned but check the polarity when instaling and before powering on because they did change the polarity in 2 places right after the fan and two yellow wires on the CR10 . it use to be negative positive and now its backwards i ran my printer for 12 hours like that before i saw it. Lucky it didnt do any damage but im sure it isnt good for it

I'm not exactly doing a simple swap of the creality control board from the ender 3, I'm planning on using this board to control a 3d printer of my own design. If the board has 2 stepper motor ports for the Z axis connected to only one driver, then would the board still provide enough current for it to drive 2 nema 17 stepper motors for the x or y axis as well, using a parallel duel Z module?

[@ChrisRiley]

PC13 will be a high pin when used and it 5v. You could use it, but you would need a relay or something like that to be able to run a 24v fan. You MIGHT be able to run a 5v fan if it has very low draw.

Other than that they are pretty much the same machine. Same screen, same size main board and same print dimensions. I have my Zero 2 which I absolutely love with a passion. It has been such a wonderful printer and the output quality is crazy nice. But the main board is dying on me. I already have the BigTreeTech SKR V1.4 Turbo and the TFT 35 **** LCD and 2209 drivers. I want to use the SKR V1.4 Turbo in my Ender 5+ and continue using the original TFT the 5+ came with. It works great. Then I want to use the new TFT 35*** and the BigTreeTech mini board in my Zero 2. And the really sweet thing is looking at the mini board it appears I won't need to cut on the original Mega Zero 2 housing to make the Micro SD and USB ports to match up with the original boards. "It seems" to be a direct perfect fit from the videos I've watched. But I won't know for sure until I actually buy the board. Well, I guess I'll just go ahead and order it and see what happens.

I'm having trouble with the Extruder fan turning on at 50degrees, Extruder fan plugged into FAN1 and part fan into FAN0. I tried writing the code like the video to #define E0_AUTO_FAN_PIN FAN1_PIN, I also tried #define E0_AUTO_FAN_PIN PC7 and can't get it to turn on. I made sure to disable //#define USE_CONTROLLER_FAN when I go to heat PLA, the board says fan @100% but its not turning on either? I know the fans work but am having a hell of a time figuring this out. if i turn the part fan on manually through the temp settings it turns on and runs.

[@Austin-tp5qw]

I believe i figured it out. i am running marlin 2.0.7.2.. I had issues with this before where i would add .bin after the firmware name (firmware.bin) I removed the .bin and then installed it into the printer and it worked right away. not sure if they have changed it so you don't need the .bin.. it actually doesn't save as a firmware.bin file, at least for me. so adding .bin made it unreadable.

I have 2 problems. 1 When I reboot with the new firmware I get an error the error " failed to enable bed leveling" From what I have read, that is because there is no data. So the second problem. Homing, Everything seems to work when going to home, X & Y go home, the extruder goes to the middle of the bed, but the Z will not go down. it moves upwards, then stops. the BLTouch does it quick reset, probe extends and then I get an error "STOP called because of BLTouch error, Restart with M999" Any help from your user or you would greatly be appreciated. Thanks in advance...CO

[@ChrisRiley]

My guess is that it thinks the Z is always triggered. Check it with m119. Check you white and black wires are on the S and G pins. Try switching these marlin settings. #define Z_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Z_MIN_PROBE_ENDSTOP_INVERTING false // Set to true to invert the logic of the probe.

I don't see the point on why you did all that procedure for the fan (swapping the connections, swapping the pins in Marlin etc.). I mean: you're still going to have only one Marlin-controlled fan and the other one full-blown. Thus, the overall noise won't be reduced. So, why u did that?

The hotend fan is now Marlin controlled, it only comes on when printing.

[@GabrioB]

@@ChrisRiley Ok, now I see the point! Thus, I followed your guide and I have inverted the two fan connections on the controller board. Now the hotend fan is Marlin controlled while the controller fan is always on at full speed. But I replaced the latter with a very quiet 40x40x20mm Noctua fan and since I'm sharing the rear case with a Raspberry, I think it's ok to have the fan always on (perhaps I could GPIO contol the fan from the Pi?). Not a life changer while printing, but much more comfortable while idling at least. Tnx allot for your suggestion! :)
