BigTreeTech - SKR Mini E3 v3.0 - Chris's Basement

[@KevinsHope]

So...Chris....you keep talking about why its important to go over hook up even though you've done it before. That was the part of this video most important to me. When I realized they had changed the hook ups (removing the fan screw in), I was like...wth? Opened the instructions which referred to one hook up as hb, which I had no idea what that meant and they didn't define it. I hooked it up, thinking maybe it meant heated bed, but I wasn't sure. Your video helped me VERY much by confirming where that fan went and what needed to be in the screw down plugs. Also, I had all my fans hooked up in the wrong place. LOL Thanks for taking the time to go over hook up again. That is what I needed to see. Thank you, thank you, thank you.

Awesome to hear, I am glad these are still useful.

Can you set the stepper motor current. I didn't see any trim pots. Thanks Chris! Your videos are so helpfull.

[@ChrisRiley]

Yes, depending on the firmware you can run a command to set it. In Marlin it's M906.

[@beezaa]

Appreciate the installation guide. I just went to install mine and was scratching my head trying to figure out how to connect the hot end fan. I just assumed I would be able to plug and play. This video cleared things up.

Didn't plan on an upgrade, but my new Sprite all-metal hot end has a bltouch connector that won't fit into the BTT SKR Mini E3 v2 (it has a port for it, but it has a form-factor for a three-pin and a two-pin connector, instead of a straight-5 pin connector). Great video for covering everything I needed!

And... I also did get the yellow duck, the crown of victory on my board upgrade!!!

[@parker1ray]

I have moved way past the Ender series printers, but still have my very first old original Ender 3 standard. I recently upgraded it with this board and the CR Touch! It has many other upgrades, and still prints very well! I have two Anycubic Kobra 2 V2 that prints at 150 mm/sc. These print in a fraction and came with runout, power resume, auto mesh leveling, and direct drive extruder, all for $200.00.

That's awesome! Those Enders are pretty good!

Hi, is it possible to connect LCD 12864 to this board BIGTREETECH BTT SKR Mini E3 V3.0?

[@ChrisRiley]

You would need a converter or use a ENDER 3 style screen.

[@YahWho-is1tt]

Hello Chris - I'm HOPING you might spot this, in spite of the age of this video??? I want to pick your brain for your off-the-top guess on where you think I might need to look first: about a year ago I upgraded my old Ender 3 with this SKR Mini E3 along with a BTT Pi in order to move into Klipper. For the most part things seem to work (from Klipper (mainsail) anyway) - BUT -- I can no longer print directly from the printer's control knob! I can "see" all the gcode files of jobs that have already been uploaded/printed, but there does NOT seem to be ANY way of selecting one with the knob/switch. Other things in the menu system seem to work (like setting temps, homing and manual moves of the hotend) but it sure would be nice once in awhile to fire it up and print something without all the steps of mainsail. At least for prints that have proven successful already. The other odd thing is that there is no way to connect to the SD card slot in the Mini - I can only see the card that the Pi boots from! Have any guess? Thanks in advance - even if all you do is read this and round-file it!

[@ChrisRiley]

Not sure if you have seen this one, kzbin.info/www/bejne/naavl3yYiK1gf8k but the only thing I can think of is the pins aren't mapped correctly for the mini to the screen. I remember there being some strange stuff with the LCD in Klipper, like it would set the print ready, but not start it or something like that. On the SD card on the board, that is standard fair for Klipper, it only talks to the MCU to load firmware, so Klipper can access it.

Even if it's blank, it should be okay to turn it on. It's probably a firmware config. Do you know what screen this is?

Just received my SKR Mini E3 V3.0, 9/22/2022. The processor is STM32G0B0RET6. The data sheet on this says it is 512kb flash and 144kb SRAM memory, 64Mhz.

For the BTT Mini 12864 LCD's there's a way to wire and mod the firmware to work with the neopixel pins and EXT connector since it's missing EXT1 and EXT2. It's a pain but it's available and no SD support unfortunately.

[@ChrisRiley]

Nice! I didn't know that, thanks Mitch!

[@impatientmaker8469]

Great video as always Chris! I just got this board to replace the v2.0 (my USB port broke off). I had some pre-wired JSTs that I could solder to the fan wires, and discovered that there are two standards for polarity with JSTs. There is the original RC standard which is opposite to this board, and there is also, for lack of a better word, Arduino standard, which is correct. Just wanted to mention for folks that get pre-wired JST plugs.

[@ChrisRiley]

Thanks a lot!

[@tappiera]

Reading your comment a bit too late myself 😅

[@alejandrorugero]

in the ender 3 pro in the green sockets there is a fan, the first 2 negative and positive, you don't say the cables where they are placed, and by the way, what fan is it? and on the board that you show there are only 2 connections for the bed and the hotend.

[@ChrisRiley]

Check the pinout for polarity. Fan0 is the part fan, fan 1 or 2 can be the hotend fan or controller fan. github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/hardware/BTT%20SKR%20MINI%20E3%20V3.0/Hardware

[@goesintite]

Could I use a Z axis proximity sensor instead of the bl touch sensor? If so, which pins would work with this? Could I use the bottom 3 Z probe pins?

[@ChrisRiley]

It depends on the sensor, but yes, it you still want to have a Z min switch the probe pins will work.

[@goesintite]

I'm assuming you mean the BT sensor pins? Thanks, Chris. I burnt up the board btw. DoH!

As far as the firmware goes, it won't matter for the PRO, you should be all set.

[@tonnyprasetya48]

Make guide for mk3s with SKR mini E3 please!!

[@ChrisRiley]

It should work the same as the Ender 3, but you will lose all the Pursa firmware goodness.

@@ChrisRiley im so noob on custom programming like this but i have prusa bear kit i used to use with my prusa mk3s. Now mk3s back to stock i have left with all frame & linear rail, just need printed parts and electronics so im planning to revive that with fly e3 pro.

It can go in a few different spots. Try FAN2.

Make sure you have the serial set right. Serial 0 should be -1 serial 1 should be set to 2. Make sure the baud rates match.

Hi Chris How do I use this board to run a diode laser engraver. Have an old laseraxe running with the original arduino mini and driver board

[@ChrisRiley]

I don't know much about the laser setups, I've never tried to do it.

[@axelollars]

I had the 4.2.2 board and now recently upgraded to the 4.2.7 with klipper. Is it worth it to get the skr or should I continue with the 4.2.7. How much better is the skr?

[@ChrisRiley]

Unless you need more ports for some reason, they are going to be about the same.

[@GregoryAlexander-n1w]

Hey Chris! I just purchased this board and the TFT35 E3. V3 Touch Dual mode display. However after install when I try to do the 4 corner bed leveling, I get the front left and right corners done, but when I tap the button for either rear left or right it gets in position and rather than go down for the adjustment it seems to stop. However I noticed both Z motors were ever so slowly raising the extruder! I've installed updated firmware with no success so would this be a moment where I have to go in an custom edit the firmware?

[@ChrisRiley]

That's a really strange issue. I would guess it's something with the screen. Sometimes the firmware on those does really odd things. Not sure exactly how to correct it.

[@GregoryAlexander-n1w]

@@ChrisRiley Thanks Chris. I think I'm going to go back to the old screen for now.

[@Iphonedylan]

I ordered one of these boards for my stock ender 3 pro. is it required that I put those JST plugs on the fan wires? I just dont have the supplies to do so right now, I was hoping to do this on a budget lol

It's going to be pretty hard if you don't. You could get some pig tails and splice them or solder them? amzn.to/3O8V34p

[@bradleydach9672]

Will the version 3 5v outputs be adequate for a Pi 4?

[@ChrisRiley]

It's really hard to say. I don't think I would trust it running a Pi4, they need a lot of juice compared to something like a zero.

[@craftsandallthatjaz]

hello! I just installed this BigtreeTech skr mini e3 V3.0.1 into my CR10 v2 and was able to get some help for the firmware by someone else.., but I am still running with the issue for the heating process. The bed or nozzle will start to heat up and then fail after a few moments. is there a reason for this and how can I fix it? I also have 4 extra wires labeled k-fan, x limit, z limit and D11, & im not sure if I need these or what to do with them. :(

[@ChrisRiley]

Does it throw an error? Does it reboot? Sounds like you might not have everything hooked up that it needs. I would have to see a picture of the board and the wires.

[@craftsandallthatjaz]

@Chris Riley it throws an error that it failrd and needs to be reset. I do have a few wires out that i didnt know where to go, i was told by someone else that those weren't necessary but id have to show you, would there be anyway to send u a picture of that? I really appreciate the help ! 🙏🏼

Good review. I have had really good results with my BTT boards - 5 mini V2 and the Octopus. They have a good product at a reasonable price.

[@ChrisRiley]

Thanks Dave, for the most part I have had really good luck with these.

[@Eduqueebrinque]

Please help me with a doubt, I installed my skr 3.0 on my ender v1, everything worked perfectly for 10 minutes, then it stopped and gave a Heated E1 error, I believe that the thermistor of the v1 is 12V and the skr 24v, so Please help me with this doubt, should I change to a hotend thermistor for 24v?

[@ChrisRiley]

The termistor won't have a voltage rating, it's probably a firmware issue. Values for thermal runaway need to be adjusted.

[@kortt]

Thanks for your great videos, they have helped me so much over the years! Would you be willing to do a video on the BIQu Microprove v2 with the SKR mini e3 v3 marlin setup? I have both these bits coming for my Ender 3 v1 and am seeing that people are having trouble using the probe port on the board, they are having to use the Z MIN Endstop to make it work properly which would not allow the use of z endstop homing. There is a redit thread about this that talks about it I believe. Not sure if BTT has fixed this issue yet or not.

[@ChrisRiley]

Hey, thanks for watching over the years. I don't have one of those probes, but let me see if they will send me one and I will see what I can do.

[@grathado28]

But how to hook up this board to a Delta printer

[@ChrisRiley]

You will have to use the delta example in Marlin.

[@Mohound]

Thank you Chris for the video but I am having some trouble that you might know how to fix. I put in the board and everything but it is stuck on the bugfix marlin section when I boot it up. I can't think of an issue that would cause this, thanks

[@ChrisRiley]

That's not good, it won't post. About all I know to do is unplug all the connections except the LCD and see if it will post. Also, you might try reflashing with firmware from the BTT github.

[@Mohound]

@@ChrisRiley Thank you for the reply, I figured out that the firmware was not flashing unless I reformated my sd card. odd problem

Hey great video. I have a question, how to solve the problem with the 3 fans, how to control them on this board, two of them work and the third one does not, how to solve it in marline,

In the feature you would like to use with the fan, update it with the pin listed on the back of the board.

[@666Aries]

@@ChrisRiley I now that pin is PC6, it is manual control from the panel, but I want to control it by slicer, becouse that fan is for cooling filament, and when I slice the .stl the fan do not move.

The V2 screen is very hard to use on anything except the stock board. Klipper has very little support for any screen.

[@electro3976]

HI Chris can you print directly from onboard SD CARD slot with this board

[@ChrisRiley]

Yes you can, not issues.

[@0429reilly]

Hello, does this board act as a direct replacement for the CR-10S with the v4.2.2 board?

[@ChrisRiley]

For hardware, yes, you will have to get and upated version of firmware to flash it for the CR10 changes. By default they are configured for the ender 3.

[@jdjizzle]

Does the controller fan suck air out of the box or blow air in?

[@ChrisRiley]

It's blowing air in.

@@palewriter1856 I 100% agree. I finally gave up. I had the SKR mini e3 v3 TFT 25, sprite, cr touch, and all it ever did was give me the error kill code. So so annoying. So I went back to the 4.2.2 board and the stock e3v2 screen and it all works except the CR touch deploys off the bed when I auto home. insanely aggravating, but still miles ahead of where I was with the mini e3 nonsense.

How do you update this so my board works with CR 10 size I updated them as a combo

You would have to build it from a Marlin example for the4 CR10, check here. github.com/MarlinFirmware/Configurations/tree/bugfix-2.1.x/config/examples/Creality/CR-10/BigTreeTech%20SKR%20Mini%20E3%202.0 This will work with the V3 board with very minor changes.

I bought 2 of these boards, they've been sitting on my desk for a week now waiting for me to install them. I would love a follow up on this video about the sensorless set up. Thanks Chris

[@hobbyistnotes]

You just enable sensorless homing in your firmware and bridge sensorless homing pins with included little red bridge. I found it worst and more worrying than using actual switches and it's not that good as advertised. May be i am missing something important but it's from my experience.

@@ChrisRiley I have tried a lot of things. Using either an 8gb sd or a 128mb sd. Formatted at Fat and Fat32. Using firmware from bttgithub, skr e3 v3, ender3-bltouch.bin. Placed in root folder of sd and moved to printer. I have tried changing the name in all format configurations of fat. Firmware.bin Firmways123.bin. The only thing that does anything is if I rename it FIRMWARE omitting .bin as its already a .bin file. The printer will boot, pause for 2 seconds and then nothing is different with the printer. It will change the .bin file on the SD to a .Cursor file. So I am not sure what I am doing wrong. I have followed multiple tutorials all saying more or less the same thing and scouring reddit etc. Brand new skr v3 board. Thoughts?

Well it's flashing fine, so that's not the problem. You might not notice the change, I would try running the G29 command.

Thanks for the video Chris. I have two z steppers installed, would it be better to use the split cable or two separate cables and are there any issues to be aware of with either option? 👍

Both options should be exactly the same. I would just go with 2 cables I think.
