Bigtreetech SKR Mini E3 V3 Support

[anilgunduzz]

Hi,

I installed the Professional Firmware a few days ago. It's really marvelous. But I bought the Bigtreetech SKR Mini E3 V3 because of some new features like TMC2209 (sensorless homing, linear advance), neopixel led slot, third fan slot etc. I also found this little adapter for the DWIN display compatibility and ordered over JLCPCB: DWIN Display Adapter

Do you have a plan for this mainboard in the future? I would like to keep use the Professional Firmware.

Best Regards.

[mriscoc]

EDIT: Now the firmware has support for the SKR Mini E3 V3 (a screen adapter is required)
Here is a Video about of Installing a BTT SKR Mini e3 v3.0 on an Ender 3 v2: an Upgrade that Includes How-to Wire the Display

I don't have that board to allow me to do tests. Maybe I will post some experimental version to be tested by you.

[anilgunduzz]

Hi again,

I received my BTT SKR Mini E3 V3 board finally. Can you please prepare a .bin file for this board with UBL? I have also BL Touch.

Best Regards.

Best Regards.

Can you share where you got the adapter. Did this firmware work

[anilgunduzz]

I uploaded the Gerber file to JLCPCB and ordered over them. I couldn't test it yet because I don't know which direction should I connect the adapter. I don't want to burn my screen or new mainboard :/

[mriscoc]

Have you the adapter for the DWIN/DACAI screen? There are some guides on the web about how to connect the SKR mini. I don't have that board but I think that Marlin has configuration files, it could be ideal if first you try with the official bugfix to know if your hardware is correctly connected.

[anilgunduzz]

I also got this adapter: Link But I'm not sure if I soldered the sockets right. Can you please check if this adapter will work or not? Because if I soldered wrong, it might damage the screen. I know you can understand these diagrams much better than me :) I attached some screenshots.

Thank you!.

[mriscoc]

Maybe this adapter is to be connected to the screen, see the label "Top of Screen"

[anilgunduzz]

Make sense but I checked this screenshot:

for this diagram, (In my opinion) sockets should be soldered to the opposite side, so the socket marks seem not right. Maybe I'm wrong, I'm not good at PCBs.

What do you think?

UPDATE:

I just tried a few connection combinations and tested with a multimeter, and finally found the correct way to solder connectors for this PCB adapter. I Tested every pin and checked the mainboard at the same time.

This PCB adapter should be updated by the author. Otherwise, other people can damage their mainboard.

So, I'll just need a 90-degree female header, then I'll test the mainboard with the DWIN screen.

[anilgunduzz]

Update: I soldered a 90c header to the adapter.

I just tried to compile your firmware. I opened your configuration.h and configuration_adv.h files with VScode and compared them with BTT files. Then I replaced some lines. But when I try to compile, It's ending with an error but VScode is not telling me what is the error.

Can you help me to compile it?

[mriscoc]

Because PlatformIO is updating the current source code is not totally compatible. In the next week I will post new source code with several improvements and updates. Could you zip and send me your configuration files?

[anilgunduzz]

You can find them here. But I don't know if I did everything right or not.

Configuration.zip

[mriscoc]

I just compiled your configuration with a test branch. Please check with caution, I don't have any way to do a test because I don't have the board. I think that the control for the board fan is missing in your configuration. Do basic tests, don't print with this version yet.

New version here: #131 (reply in thread)

[anilgunduzz]

Firstly, many thanks to you! Screen is working! I'll gladly be a volunteer to test your firmware for this mainboard!

I did those tests:

Dwin Screen (with converter adapter): ok (a few tiny glitches)

BL Touch: ok

Tramming: ok

Mesh Leveling: ok

Hotend fan: ok (It's working only when the hotend starts to heat. I also tested it with standard marlin and klipper but nothing changed. I think this is the mainboard's feature and I love it! More silence! )

Part Cooling fan: ok

Mainboard fan: Nok (I knew I missed something :) )

Mainboard fan connected to PB15 pin.

Please let me know if you need any additional tests. I'm also waiting for print tests.

[mriscoc]

That is excellent news! I will correct the board fan later. About the screen glitches, secure the connectors, keep the wires short, put a ferrite ring.

[tjs2906]

I would be happy to help test. I rewired my cable to support my DWIN lcd. I also have V3. I have different offsets than most. Will I be able to compile my own firmware or can I send you my config files? Thank you for all your hard work.

[mriscoc]

The source will be available along with the release of the latest firmware version maybe this weekend.

[tjs2906]

That's Great! Thank you. Have you tried to enable MPCTEMP? It is a much better system to regulate nozzle temp. It almost completely eliminates temp overshoot.

[mriscoc]

Correcting Mainboard FAN

[anilgunduzz]

Interesting,
I have never seen it before. What is it and what should I do?

[mriscoc]

Delete the file and try again please.

[anilgunduzz]

Deleted the PLR file, tried again but nothing changed. I got the same error. Then I checked the sd card again and saw the PLR file again.

[mriscoc]

OK thanks, that allows me to know where to look for.

[mriscoc]

That board has a POWER_LOSS_PIN (PC12), that pin detects when the main power outage is going to occur, allowing the board to save a power outage recovery file (PLR). We are having false power outage triggers.

So, I can disable that pin or maybe you have a way to make it work for your setup.

[tjs2906]

I reinstalled the marlin ui firmware, I have power loss enabled and I don’t have that issue. I just checked again. I will reinstall your firmware and check it if you want, but I cant actually print anything because of the offsets being way off for me. Tom

[mriscoc]

Hi Tom, the problem is not with the power outage feature is only with the POWER_LOSS_PIN, when that pin is disabled the power outage feature save the PLR file at intervals of 0.05mm of Z. When that pin is enabled, the system relies on the logic value of that pin to detect a power outage.

[mriscoc]

This version disables the POWER_LOSS_PIN, please check
firmware-20220526-140647.zip

[anilgunduzz]

With this version, I checked the power outage option, stored settings and started a print. It worked without issues. I also cut the energy and tested the power outage. It's also working.

On the other hand, I am already using Octoprint. That means I can't use this feature. But I prefer this version to be available for all SKR mini e3 v3 users, not just for my setup. So maybe the power loss pin should stay functional, maybe a new menu item like "enable power loss pin" can be added, I don't know. What do you think?

[mriscoc]

I think that having a POWER_LOSS_PIN enabled is a very special case. I will leave it disabled in the precompiled binaries and if anyone need it can easy reenabled it in the configuration files and compile a custom version.

[tjs2906]

Ah ok. Looking forward to installing this on my printer, I just need to tweak offsets and bed size, min max etc. Thanks for all your hard work. It is appreciated. Tom

[mriscoc]

OK, I think that we have a finished version ready to be released.

[anilgunduzz]

With the standard options, yes I think it's ready. Many thanks to you, really!

Btw, the most valuable thing for this mainboard is the TMC2209 drivers and they are supporting the linear advance feature. Are they needed to be activated only within Marlin codes or will they support it without any additional config?

[mriscoc]

For linear advance, somethings need to be enabled and others disabled in configuration files.

[mriscoc]

Now there is a linear advance enabler json file and the corresponding configuration files have been generated: https://github.com/mriscoc/Special_Configurations/releases/tag/SKRMINI-LA

[tjs2906]

The only thing I have found that uses that pin is the autoshutdown module. I have it, I just haven’t installed it yet. When I get around to doing that, I’ll let you know how it works out.

That is a perfect example of when a custom build is needed.

I didn’t realize you could set ALL of the min/max bed size/pos, Probe offsets, etc. from the lcd. Your firmware is even more awesome than I thought. It is working perfectly so far on my printer.

Binaries and source code available in the repository.

[anilgunduzz]

So, we have an official release. This was very fast to me. Thank you again.

When you proceed to improve the firmware in the future, I'll gladly help to test new features for this mainboard. So we can always keep it up-to-date. Please let me know when the time has come!

Unable to compile in VSCode using the special configurations for Ender3V2-miniE3V3-BLT files. Getting the following build environment error: Error: Build environment 'STM32F103RC_creality' is incompatible with BOARD_BTT_SKR_MINI_E3_V3_0. Use one of these: STM32G0B1RE_btt The previous firmware I was using did use STM32G0B1RE_btt. What should I do here?

[tjs2906]

You have to uncomment (delete the # before STM32G0B1RE_btt). I did and it compiled no problems. Mriscoc is this correct?

[platformio]
src_dir = Marlin
boards_dir = buildroot/share/PlatformIO/boards
#default_envs = STM32F103RC_creality
#default_envs = STM32F401RC_creality
default_envs = STM32G0B1RE_btt
include_dir = Marlin

[mriscoc]

Yes, that is correct

[niblem85]

Yes, this works. Thanks. Great firmware, I highly recommend it for anyone with an Ender3V2 and a CR Touch because it simply just works as compared to Marlin or BTT firmware.

[krziwan]

Hi Miguel!

I have an ender 3 v2 with SKR mini e3 v3 and followed the instructions here and it works perfectly!! After struggling for days trying to have a working printer. I love the firmware!! thank you very much for your time and good work!

One Problem though. I am using Octo4a (Octoprint) on an "old" cellphone and I can't get a connection to the printer. With the stock motherboard it used to work perfectly and without glitches (also with your firmware). Do you have a suggestion? I tried different configurations and I am using the cable provided with the board and nothing. In the phone when I try to select each of the serial drivers it shows " requesting permission to device" and it doesn't get it:

Hi!

I had to change the driver to the CDC mode in the Octo4a app and it worked!

Thank you!

[okcub2010]

I have several pin 27 boards I won't use again. I'm thinking I'll cut and rewire the trace on one.

I used a piece of scrap print to stabilize the board.I need one more so my next version may be more refined, or not! Once installed it just stays there and works.
Great original idea of a adapter board I borrowed the idea from. Thank you.

[theSt33v]

@mriscoc Have you started creating a version of this for the S1? If so, I'll be ready to test in a few days. I finally have all the parts needed to create my breakout cable for the sprite extruder assembly.

[mriscoc]

S1 with a SKR mini E3? I Think that you could use the current firmware for the SKR and only adjust the physical dimensions and offsets.

[theSt33v]

Awesome. I'll give that a shot and let you know how it goes.

[theSt33v]

I now have a fully working build of the professional firmware for the Ender 3 S1 + SKR mini E3 V3. If you're interested in adding this to your support list, here are the configs.

[Moobien]

As per advisement I am posting these questions here.

Hey Folks, I got my SKR Mini E3 V3 installed today and I have a few questions I was wondering if the community could help me with. I will say in advance that I have NEVER compiled firmware and have absolutely no idea how to so please if you help me, treat me like a luddite lol.

Questions:

This board has a neopixel port. Is there any difference between NeoPixel and RGB or are they interchangable? ie can use any RGB strip. The main question for this is can I control this via firmware?

The board supports sensorless homing, does the firmware support this also? (I probably won't use it myself)

The board has a third fan connector for the board cooling fan so all 3 fans have independant ports. Is there any way to have control over this fan?

3a) I did notice that when I turned on the printer with the new board the c

ooling fan for the hot end didn't seem to turn on.

I know I am probably gonna have to compile my own firmware for all this so is there any GOOD 'firmware for dummies' resources I can use to guide me through this?

[mriscoc]

For reference if you buy a premade cable to connect the screen to your SKR Mini E3 V3 board take note of this:

If you connect the cable incorrectly the screen will not turn on or pressing the encoder button will reboot the printer due to a short circuit.

[Moobien]

I got that cable, it is worth the money as there is less fiddling around.

[Stemwrench]

Not sure if this the thread to put this or in firmware but i have this board. I flashed with the SKRME3V3-BLTUBL-MPC-20230312 bin and realized that the screen will reboot after i try to do another print. The screen doesnt shut off. But hotend fans and bed turn off for like 2 seconds and the banner appears again and i'm able to start printing again. is it something i have to look in firmware or do i have faulty sd card?

[badaszszsz]

I am lost connecting my fans. I seen three resources to get this info.

Solved thanks to @Moobien - ref: https://www.makenprint.uk/3d-printing/3d-printing-guides/3d-printer-mainboard-installation-guides/btt-skr-mini-e3-v3-guides/btt-skr-mini-e3-v3-setup-guide/#thermistors

To which connectors should I connect

• Chassis / controller one Edit - quote: Board Controller Cooling Fan - Additionally, the FAN1 connection is located idyllically for use with the fan that helps keep the mainboard cool. Like the part cooling fan, the polarity is with the red positive (+) wire to the left and the black negative (-/GND) to the right.:
• part fan Edit - quote: Part Cooling Fan - By default, the connection for the cooling fan for the filament is FAN0, with the red positive (+) wire to the left and the black negative (-/GND) to the right.
• extruder / hotend fan Edit - quote: Hot End Heatsink Fan - Finally, the fan connection for the hotend heatsink fan is the FAN2 connection. Once again, the red positive (+) wire to the left and the black negative (-/GND) to the right.

Marlin issue: MarlinFirmware/Marlin#17301
saying in comment:
0 - chamber
1 - extruder
2 - controller
which is not understand by me, as controller/chassis=chamber? is the same? so where is part cooler there?

I seen comments in this (unrelated to SKR board) file:

Ender3V2S1/Marlin/src/pins/stm32f1/pins_CCROBOT_MEEB_3DP.h

Lines 117 to 119 in cef4e6d

	#define FAN_PIN PA7 // FAN (fan2 on board) model cool fan
	#define FAN1_PIN PA8 // FAN (fan0 on board) e0 cool fan
	#define FAN2_PIN PB9 // FAN (fan1 on board) controller cool fan

in V3 I see:

Ender3V2S1/Marlin/src/pins/stm32g0/pins_BTT_SKR_MINI_E3_V3_0.h

Lines 137 to 139 in cef4e6d

	#define FAN_PIN PC6 // "FAN0"
	#define FAN1_PIN PC7 // "FAN1"
	#define FAN2_PIN PB15 // "FAN2"

with no description.

Also, I see additional naming convention not found in BTT SKR MINI E3 V3_0 header:

• CONTROLLER_FAN_PIN
• E[0-7]_AUTO_FAN_PIN
• CHAMBER_AUTO_FAN_PIN
• COOLER_AUTO_FAN_PIN
• FAN0_PIN pointing to FAN_PIN
  not definied in SKR e3 v3 board.

Is there way to prepare more documentation? Where I should reference to if want to prepare it? Thanks in advance

[Moobien]

I simply plugged them in according to this webssite and they worked. https://www.makenprint.uk/3d-printing/3d-printing-guides/3d-printer-mainboard-installation-guides/btt-skr-mini-e3-v3-guides/btt-skr-mini-e3-v3-setup-guide/

[badaszszsz]

okey thanks @Moobien , how your experience? Have you compared with Klipper?

[badaszszsz]

btw. on 422 ealier with 3 v2 Neo I got some improvements on printing when increased resolution approximation w/o Klipper. I heard that Klipper is very nice and wonder what you think.
And if you checked out Linear Advance on SKR

[Moobien]

okey thanks @Moobien , how your experience? Have you compared with Klipper?

Never used any firmware other than stock and this one so no idea

[Chris-Jayden]

This is more of a general question with respect to Marlin and the physical pins instead, but...

Does anyone have any insight on why all the quick-fixes (for making Ender 3 v2 DWIN LCD screens compatible with SKR Mini E3 and SKR 2 motherboards) require physical modification to the LCD wires in addition to the changes in the respective Pins.h?

Is there a physical constraint with the MCU such that we cannot simply change the respective Pins.h in Marlin to match exactly without needing to also physically modify the LCD wires?

Would it be a constraint related to the ground, voltage, RX, and TX pins not being able to be re-pinned-out?
I would assume (possibly incorrectly) that we would be free to adjust the pinouts of signal pins at the very least

[Moobien]

Honestly not sure, i paid 10 dollarydoos for a cable that was already the correct configuration to do this.

[Stemwrench]

that would be a nice feature for a hopeful marlin updates/upgrades. yes, i did buy the cable as well but it be nice to actually learn and change the pin-outs ourselves to make the current E3V2 display ribbon. especially if youre commissioned individual to prevent downtime on products. hopefully this could be a compatible thing.

[mriscoc]

Power and serial pins can't be changed via pin definitions.

[Comicrocket]

has anyone figured out how to get the hotend cooler fan to work for plug (fan 2) ?

[mriscoc]

I think that fan turns on automatically in the SKR MINI V3 E3 when the hotend is at 50 °C

[Moobien]

Mine turns on whenever the bed is heating

[rapinball]

My Hotend and enclosure fan is running correct after switching the plugs. Put your hotend fan to the enclosure fan plug and the enclosure fan to the hotend plug.

[rapinball]

Hi all,
is there an MRISCOC precompiled version for SKR3mini v3 with BLtouch , input shaping and linear advance enabled?
I only found with bltouch and linear advance.

[rapinball]

By the way....best firmware I have seen

[mriscoc]

There isn't a precompiled one with LA and IS for SKR.
https://github.com/mriscoc/Special_Configurations/releases/tag/sponsored

[rapinball]

No problem.I managed to compile one by myself with your configurator. I made a donation today. Just to let you know how amazing your software is. I love it. Best software I have seen. After about 6 different printers. You software is amazing. Has everything...easy to use. Amazing job. I wish you all the best Sent from Outlook for Android<https://aka.ms/AAb9ysg>

Follow that:
"CAUTION! DWIN_CREALITY_LCD requires a custom cable, see diagram above this line. (Define NO_CONTROLLER_CUSTOM_WIRING_WARNING to suppress this warning.)"

[rapinball]

Did you to undefine (//) the lines referring to the custome cable?

[bagsofcole]

Thanks guys. I thought it was ‘no editing required’. I’ll check that out. Thanks,RoyOn Nov 26, 2023, at 10:17 AM, rapinball ***@***.***> wrote: Did you to undefine (//) the lines referring to the custome cable? —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you commented.Message ID: ***@***.***>

That line is a warning because if you connect the screen with the wrong cable it can damage the board.

Hi,

has anyone already found a solution for the probe fails with a BL-Touch V3.1?

It's not the hardware. There are no problems with a 4.2.2 board.
I have already destroyed two PEI permanent printing plates because of this error.

I found this, even more guys have this problem. If I understand correctly there is no real solution
MarlinFirmware/Marlin#24351

[mriscoc]

In the comments of that thread it is mentioned that there appears to be a hardware problem with the E3V3.

[MRichter187]

I have an ender 3 with a BTT SKR E3 V3 paired with the BTT TFT35 display. Can I run mriscoc? If so how to get firmware and where
