Bigtreetech SKR V1.4 (Turbo) comprehensive guide

The SKR V1.4 is an update to the hugely popular 32bit SKR V1.3 from Bigtreetech. It now has more available add ons and also a ‘turbo’ variant. In this video, I will guide you through everything you need to know about this board and its configuration. This includes a buyer’s guide, differences, resources, firmware, wiring, various stepper motor drivers and accessories such as the BLtouch and Neopixels.

If you are happily running an SKR V1.3 there isn’t necessarily a reason to change to this new board unless you are after some of the new features.

This board was supplied to me free of charge by Bigtreetech for the purposes of making this guide. All opinions expressed are my own.

I have an Ender 3 Pro and replaced with BTT SKR 1.4 Turbo along with the original 12864 LCD Control Screen (came with printer). After doing everything Michael mentioned in this VERY HELPFUL video, I ran into ONE ISSUE. When scrolling down to print off the SD card I would only see "Attach Media". ... After many hours and taking out whatever hair I have left, I noticed under "configuration_adv.h" that the #define SDCARD_CONNECTION was set to LCD (#define SDCARD_CONNECTION LCD). Obviously there is no SD card slot on LCD. You'll need to change it to #define SDCARD_CONNECTION ONBOARD . Flashed the Firmware and finally I see the "Print from Media"! Hope this helps others with the same or similar setup.

I just received mine today and started with the struggle...best timing Michael!! Your channel is by far the best in the 3D printing upgrades department (specially ender family) and the quality of your explanations

Literally just bought a SKR 1.4 Turbo 2 days ago, this video comes more than perfect!
Thank You!

Very informative!
Few have covered these board as well as you have!
Looking forward to more of your content on the BIQU line. 👍🏼

[robdavidowitz]

Absolutely AWESOME and outstanding instructional video.
As a complete novice, this upgrade seems quite daunting for me but after watching this video and related link video, I feel confident to go out and buy the bits and pieces and cracking on with this installation.
I might get to eat my words but I somehow doubt it, given your extremely detailed step by step.
BEST instruction video I have seem in a very long time
Good on you Boet👌👍

In order to use bltouch proprietary connection in skr 1.4 board, you must change the pins port in pins_BTT_SKR_V1_4.h file.

From:
#define Z_STOP_PIN P1_27
To:
#define Z_STOP_PIN P0_10


Great content teaching tech, keep going!

[Commandos]

thank you very much, if it weren't for you, I wouldn't have realized that the problem was in the driver pins, I bent them as you did and everything became super)

[gibbnal]

Thank you for doing such in-depth guides. Tonight I upgraded my CR-10s to the SKR 1.4 with 2208 drivers and it went just fine. But it’s very easy to skip something and waste tons of time figuring out the mistake. My advice for noobs like me is to watch, listen and re-watch. Excellent content. Keep up the great work. 👍

i just received my BTT skr 1.4 turbo in the mail today.. your video is gonna be super helpful when im doing the install.. thank you so much keep up the stellar work

[Lozoot]

I was an early adopter of the 1.3, back before there was hardly any documentation - I'm absolutely amazed at not only how quickly this board became a staple in the 3D printing community, but also how awesome BTT has been with fixes, improvements and features that their customers can actually benefit from! It's nice when companies listen to feedback :D

[HotboiEngineering]

Looking forward to the Closed Loop Stepper video, i've always wanted that Prusa style step loss protection.

[quebecmultirotor]

thank you much Michael! i struggled for 2 days getting that bltouch hooked up and functional watching your video pointed me in the right direction .... my connections where wrong

I have an SKR V1.4 Turbo on order with the TMC2209 and a TFT35 V3.0. I've never performed any of what you've shown but understand what's going on and your video....well...so amazingly well done, to the point with sufficient explanations. Looking forward in executing this project which will involve replacing my controller box with something designed differently, maybe that one from Thingiverse between the frame rails. Thanks for a nother very informative video, I learned a lot.

So I've watched this guide multiple times start to finish and it's amazingly thorough. With that being said my ender 3 has been out of commission for about 2 months since I did this upgrade. I followed everything to the T and haven't gotten a successful print since the upgrade. Things I changed are SKR v1.4 Turbo, BLTouch, and Hero Me Gen 5. The issues keeping me from getting a successful print is as follows. When I try to home, the X axis will move slightly then home the Y and Z normally. I tinkered with the sensorless homing sensitivity but the issue is let's say at 55 it moves ever so slightly and stops as if it's homed and at 54 it crashes into the endstop makes a horrible sound until I power off the printer. There are times it doesn't do this so then I move on to bed leveling with the BLTouch, for the most part it levels the 9 points on the bed fine but sometimes when I get to this step it probes off the bed as if the offsets are off but trust me, they aren't. I've gone through the marlin rebuild process about 10 times now, each time starting from scratch and patiently ensuring all the settings are exact and perfect. Another issue is if I make it passed the bed leveling stage and attempt a print the printer acts as if its not leveled and prints like a whole 10mm off the bed and no amount of Z Offset seems to help with this. I've even gone to the extent of disassembling the entire printer and reassembling to make sure everything is square and not built unevenly. I pretty much gave up about a month ago after spending literally 10 hours straight marlin, and yes I mean literally my adhd had me in hyper focus mode and did break focus until i noticed how thirsty I was. It's just such a grab bag of issues that I don't know where to start or what would cause what issue. Like the issues I mentioned intermittent like I can have it to where the sensorless homing sensitivity is good enough to where the X will crash but stop after that which is annoying but hey atleast it's moving right? Then i get to leveling and it'll probe off the bed so I have to restart and now the sensorless homing isn't working? but the bed leveling is? makes no sense. I'm not trying to bash your video just really really want some help so I can actually print things again.

amazing video, thank you for all the info and time you put on this

Alter Falter! Bestes Tutorial zum Einrichten des SKR 1.4 Turbo im Internet. Sehr detailliert, kenntnisreich und professionell präsentiert. Weiter so!

[kevinm]

This is awesome, I have my turbo version with TMC2209 drivers ordered and will be here the 23 and this will come in SUPER handy to help me get my Ender 3 Pro setup. Thanks a ton for doing this U rock! Be safe in these trying times and keep up the awesome job you do for the community!

[eskbuilder]

Extraordinary as always Michael. Looking forward to future BTT videos. Interested in the closed loop steppers and ups module.

[yuriynovomail]

Thank you man! Very complete and quite useful! A lot of things shown that were missed by other reviewers

[RileyMoses]

Just wanted to let you know that you consistently nail the presentation for this stuff. I'll be sitting here watching and think of a question, and BOOM, five seconds later you either answer it or link to something that does. Thanks for never assuming your viewers already know what you're talking about, it's super helpful!
