Big Tree Tech 7" Touchscreen TFT70 V3.0 - Super Cool - Chris's Basement 

I'm glad I found this video, I was just about to order a TFT35 V3.0. At the beginning of this video, you asked "Who would ever need a 7 inch touchscreen on their machine??" How about guys like me who don't really have good eyesight, or even arthritis, and working smaller screens isn't really all that easy. This was very informative, and well explained. GREAT VIDEO!!!!!!

Thanks Chris. Just installed a TFT50. Your videos are always clear and helpful. Geoff

It's amazing not only what you can do with these things as far as creating, but the amount of upgrades there are. Not sure which I enjoy more, the tinkering with the printers, or printing itself 😂 Either way, love the technology and education I've gotten and will get from this. Thanks for your channel and all you put in.

Been watching for a few years now, but hot damn this last year you've been crushing it 10x with these klipper videos. Got my pi ready for klipper which I never thought possible when I started from scratch a few years ago

Great video, and nice update to the surround as well. 👍 I should hopefully have a frame mounted back panel sorted soon.

Hi Chris another brilliant video so easy to follow from installation to set up. Always inspirational

Really love the way you explain and show!!

Excellence video. Lots of good info here. Very precise and easy to follow. Thanks Chris

DANG DUDE! Didn't know they had one that big! That would definitely help with seeing easier and make your printer look good.

Looks really nice! Good video as always Chris :)

I picked up one of these because, while updating the case for my TFT3.5 I managed to reverse the RS232 connection. Even a guy with decades of electronic experience can screw up! It let the smoke out of the wires/IC's. I hate when this happens! Anyway, my 3.5 is toast and I went a head and ordered this TST7.0 v3.0. Old guy eyes might benefit using this screen. So, double check the cables are going to the correct pins. Thanks for your videos Chris! I always learn something new. You are a master at communicating what really matters!

Well, ... Timing is EVERYTHING, my Mini e3 arrived today, my TFT70 should be here Fri. Thanks for the setup tips.

Nice, I was just looking at these! Thanks

And I thought full screen of Marlin mode was stretched on the smaller BTT screen. lol. Very cool. Thanks Chris!

Very nice Chris Looks like I’m gonna have to have a 7 inch display on my ender3.

Yet another one of your videos saved Chris, screen on order...:)

cracking video as usual chris

Yet another great video👍 one note you can also copy config.ini to the sd card and have your settings changes made there instead of firmware. It's a new thing from BTT

I recently bought a 7" touch screen android head unit for my car. They are probably using the same panels.

Fantastic video

Great information.

the slow motion pealing got me 👌

The fun part Chris, is that the display uses an stm32 processor that is more powerful than those in typical printer mainboards. I wonder if the same thing could be whipped up using a Nextion display... A nice video Chris!

Thanks for this video! I used it as the guide for what i tried to do. On the BTT github for firmware it says that the screen can be oriented to 90 degrees if you need to so I decided I needed to do that to my TFT50. The process did not go well. The first hurdle was it kept failing when I tried to compile. Turns out I had to upgrade platformio. The nonupgraded version I guess has a bug that keeps saying file not found. Once I figured that out, it failed the first time but I hit compile once more and this time it was a success. I got the change listed on the github (uncomment "; DPORTRAIT_MODE") done and compiled the file, I saved all needed to the SD card. All included the new FW in the PIO folder, the language file the config file and the TFT file for the theme I wanted and the reset text command. Went up to the printer and it did indeed switch it to 90 degrees and could tell because all of the config loading was happening in portrait mode. It got to the bitmap files, flashed an error message but kept going. I figured out that it was looking for a "logo_portrait" bitmap file so I changed the name of the logo bitmap file to that and finally the entire process completed. I reset the printer and I had a portrait mode screen. So I thought. The screen moved super slow when switching between different functions and the font was overlapping and incomplete on several items. I ended up going back to landscape mode and leaving it like that.

Worth it for a speaker :) Maybe add a small grid to allow more sound out, play a tune when finished printing, change filament indication, etc...

Sweet holly mamma! Like it;) was thinking to buy one about month ago but once the btt published new firmware and install it to 3,5 v3 and think I do not need 7’

Great video Chris. 3DJIMMY would have loved that huge marlin screen,lol

Great vid Chris. Question: @ 14:00 do I need to edit the TFT LCD firmware to match the size defined on my BTT mini v2 firmware for bed size Min_Max? - Would that be a conflict? Thanks man.

Thanks for this tutorial. i went through all the steps to upgrade my TFT35 and TFT70. While with the TFT35 everything went well by compiling a custom firmware, with the TFT70 not all the customizations (preheat temperatures, table dimensions for example) had no effect after flashing. Many settings like the changes display colors and language were set correctly. I have tried compiling several times with VS or Atom, the compilation was successfully but settings was not. Then, I add to the SD card with the TFT70 folder and the firmware the config.ini file too, with the settings I wanted and only in this way the firmware has received the changes. So if someone has an issue like mine try this way to have a personalized configuration.

Now from last upgrade of v3 even 3,5 you can control junction deviation ;)

helpful for the visually impaired.

I just got this and hope it works with my MKS Monster 8 v2 board.

That music for peel was a winner

I got one and love the screen

Are going to do a video on the new marlin style tft generic displays? The new feature they added in the latest update.

Hi Chris, great video as always... i should like to how to configure Mixing extruder and z alignement on that screen , how the image comunicate to send command on that.tks

Chris, first that you so much for this guide. I got the TFT70 and am trying to get it up and running and this is very helpful. I do have two questions. First, do you enable both the CR10 display AND the REPRAP_DISCOUNT..., or just one? Second question is I have a SKR E3 Turbo V3 and am not sure which port number combo to use. Any idea on that?

We the elders appreciate it...and the sexy peeling too!

wow thats a really nice screen :)

Hi Chris. A very good video with a great explanation on the set up. I have the 7" screen. I managed to print the cover but I am having a real problem orientating the base stand for printing. I am using Cura 4.8 for my Ender 3 Pro. Just lacking experience, can you give me any clues as to the best way to orientate the base on the build plate. Just about to pull what's left of my hair out. it is a real good mounting for the screen. Regards Ernie the old newbie from Australia

Was gonna buy a skr3 ez and since i dont want to start cutting parts of the aluminum case of the ender 5+, i was wondering, do you still need access to the board usb and card connector when you get all those ports on the screen? Like pluging a raspberry pi in the screen usb port?

Hi Chris, i love your channel. Have you heard anything about Biqu kickstarting a new Biqu BX model?

Awesome.. I have the same screen but in 3.5" and at the beginning I wasn't able to make it work in graphics mode, there was an error like printer not connected (marlin mode worked ok). Every post I found said the problem was a wrong baud rate but in my case wasn't the problem. At the end the problem was in the marlin config, I had only defined one serial port, when I defined the second serial port and compile, the graphics mode worked ok (like you recommend it) ... The same message appears when I turn ln the printer but it last a couple of seconds and it disappears

slow motion peeling in 4K ...... ohhhhh yeah :D :D

It would be nice if they can add a third mode to this screen to connect a raspberry Pi touch mode , Marlin mode , octoprint Pi mode :)

Great Video Chris! Do you use EXP1 and EXP2 as well as the AUX1 for a ramps board? or just the Aux1?

I'd like to know if its possible to let the knob enabled at the same time as touch mode.

I've had mine for few weeks but marlin mode is working. Got a few things to tinker with before I know if it falty but definable looks good on core xy printer

Thanks for your good VIDEO. I want to use Thais to run a CNC . Do you know if there are icons and firmware available for this purpose?. Thanks In advance

great video, i got one of these thanks to you. got it working.. but i also had to modify the printer firmware, I still have one question: there is a ps-on connector there, would that by any chance turn the printer off after printing? if yes.. is there any tutorial how to do it? switch main power with ssr ? or something else? Any hint would be very much appreciated. Luc

Great video Chris. I was like the ability to switch back and forth between Marlin and Touchscreen. I would like to order this screen and setup with my Raspberry PI 4. Is it possible to use this screen, Octodash and Marlin that way still have option of the push wheel?

Hi Chris, I'm building a large 3d printer, this touchscreen is great for my project.

Nice details Chris. One thing I’m not seeing is the ender3 micro SD card listed, only usb and tft card when print. Not sure where I missed that setting.

Ok ok ok.. I see so this firmware will work on the 3.5" one? I love the idea of sending gcode directly from it while tuning.

Would you know is that "Reset Defaults" , returning the values etc that were just uploaded ? ,or does it , return values to default factory settings ?

making the icons larger isnt my issue, its that these larger screens are a different aspect ratio to the smaller ones. those are 4:3 and these are 16:9, and the icons and text just looks weird. in touchscreen mode its usable but marlin mode looks like when we first got widescreen TVs and everyone stretched old 4:3 content on it. off topic, are you going to check out the BTT expansion boards, I just got the reprap firmware wifi expansion board

Hey Chris. I have a skr 1.4 with the smaller touch screen. I would like to use the dual mode on the screen with ONE ribbon cable. I do need sd support from the tft. What do i need to do with firmware and wires?.... thank you

Who needs it? I do people with a visual impairment lol. Unfortunately I had already bought the 3.5 when this came out.

Hi Chris nice video. Can this be added to a Ultimaker2 with its standard white board

Chris I know its been awhile since you have done this video, which is great by the way. I done loaded the zip file from GitHub but when unzipped and loaded into VS code there is no .pio folder. compiled file successfully but don't know where the bin file is now located. Any thoughts?

Overkill. I want it!!!

Haha, I literally Lol'd in the intro

If you'd like some prettier user interfaces for the touchscreen mode on BTT TFT's a member of the community that goes by theveel has a patreon where you can download his graphical updates which are really slick looking.

When plugged into a Skr e3 V3 will in still run on klipper or will it have to be plugged into pi and klipper screen use only.

Does board filament runout (so sensor on board not screen) work with OctoPrint and a screen now? Last time I tried a screen like this, it wouldn't properly pause the OctoPrint job when the screen was used. So it was either no screen or no filament runout...

If you are planning on using this screen with the SKR1.4 Turbo, along with the expansion board (BIGTREETECH Module BTT EXP-MOT V1.2) in UART mode, that takes up both EXP1 & EXP2, then would be unable to use Marlin Mode on this screen, correct?

can you use the color ui marlin touchscreen or just the classic?

Are you doing closed loop drivers like s42b on skr 1.4 board? I'm not clear on the jumper setup and marlin 2.0.6.1.

Is it possible to do thumbnail print previews on any of the tft dual screens?

Awesome VIdeos Chris just a bit of a note i followed the video and the one on configuring marlin for a SKR Mini i could not get my TFT35-V2.0 screen to work if anyone has this issue i sugest making sure you check the version your running and update to the latest version it fixed my issue right away of "no printer found"

Hi Chris Is there any know way to get a BTT TFT to control a second extruder and second fan? I have a TFT35 but am unable to control the extra extruder and second fan. If there's a fix or recommended screen, please let me know. Thanks.

@Chris Riley I have a question ❓ I purchased a BTT TFT 70 V2 a few months ago and wanted to use it for a voron 2.4 with octopus 1.1. Well there's no bin file or anything, do I need all that if I want to run klipper screen with my raspberry pi 4 an octopus 1.1? Someone else told me that I could use the TFT5 inch firmware or TFT 70 V3 ,is that true? Or is it possible to create a firmware compatible with my screen using platform io?

Has anyone created a larger screen like the one you showcased to replace the small screen on the Prusa i3 MK3 printer?

I have this screen. I intend to mount it to the front of my printer at an angle, attaching it to the extrusion.

I've tried loading the firmware how u stated with the tft70 bin file along with the themes. However my screen won't switch over as yours did and my info is still showing original firmware.. I'm using a micro sd plugged into the usb port. Will it not update through usb?

Does this screen also have a resistive touchscreen? Looks like it, would be very 'oldskool'.

Chris can can this case be printed on a xtandard Ender 3 Pro?

Do they have firmware for CNC? I tried the MKS and though i was able to get 2 jobs ran it bricked at the end of the second job by freezing at 100% complete and upon shutdown all i got was black screen after that. i have an stlink cable coming but not fond of their closed source

What would make that perfect is a wireless tablet style connection to the printer.

So had my TFT 35 working well, but then got a "Flash App" error. Had to reload the .bin file but this continues to show up when I start my printer. Any idea what maybe going on here? I'm not always successful reloading as the error shows up when it starts to load.

Thanks Chris, I purchased the BTT TFT50 V3 so the steps would be the same only using the TFT 50? I am hoping that the update will fix a problem with the BTT Smart Filament Sensor. I am having issues in modifying my firmware to work with my new settings. I have a BTT SKR Mini v1.2, BLTouch with offsets of X-48, Y-10, Z-4.68, BTT TFT50 v3, and the BTT Smart Filament Sensor using the PT-DET input (PC12). I can get everything to work fine until I added the Smart Filament Sensor. My LCD screen will send a message in the "Info" box of "Insert Filament and press button" but nothing happens then I get a message of " Heat Nozzle Press Button" The Filament sensor on the LCD screen is set to On. I recently heard that there is a bug in the LCD TFT that won't allow the sensor to work outside of Marlin mode?

Might want to check the TFT pins on the SKR 1.4 as I believe they are 180 Deg rotated compared to the the 1.3 !

😆 🤣 nice peel

Hello Chris, this is great, i saw your video and bought one, i did everything like you said, i have a SKR 1.3 i set the serial ports like you said, and i get the “no printer attached” message, baudrate is the same in the TFT and The SKR, any idea? Thanks in advance.

Hi, I love your videos. Thanks a lot. Is it possible to use this TFT70 screen with SKR 1.2 pro board ? I'm planning to build my own Core XY printer so it would be very sexy with this TFT70 screen; LOL

I have the. TFT50 and love it but after my upgrade to SKR 1.4 turbo from SKR mini 2.0 the screen won't turn on with both cables connected. unplug one and it powers on, reconnect it after its on and its fine...ideas?

A crocodile Dundee fan ;)

Just out of curiosity, the default firmware on those SKR boards is Marlin too or just based on Marlin?

I know its not really useful but can you cover how to enable the games? I found the option in the marlin firmware but I'm guessing I need to build the screen firmware as well

Her Chris, I've gone through all your videos and appreciate your work. My TFT doesn't consistently control the printer or it has a very long delay. This can be really bad when bed leveling or baby stepping. I've double checked baud rates and everything else i can think of but always end up having to switch back to Marlin screen mode to get it to work right. Any ideas? Thanks!

have u a link 2 the programming of the wifi module for this board

Does that screen work on the lerdge K board?

Great video! I'm not gonna lie, I would have paid more money for LONGER CABLES!!!!!!!!!

question what diffrance does it make with diffrant baud rates

Hi Chris. I was following this video to connect my new tft50 to my new SKR3 EZ but no matter what I try, I can't get them to connect. So I checked the pins and found the TFT50 has tx and Rx while the board has PA9 and PA10 which don't appear to be declared in Marlin. Any assistance would be greatly appreciated. Cheers. John

7 inch now, how long before we go 15? Cool feature I want is Remote Desktop....coming soon!

I finally have a BTT TFT70 as well. My Mainboard is a SKR 1.4 Turbo. Sadly I´m not able to reach the Marlin menu. My Cables are plugged in as shown in the Video. The BTT Menu works perfectly fine (except of the "All Low" Error message at the beginning). When I want to change to Marlin it shows "Marlin" at the top but nothing else. In the Firmware I was´t able to set the Baudrate to 115200 because a Error message accured immedeately. Is the Baudrate the Problem or what have I done wrong?

if i remember correctly the setting for the ports is not correct as if u use certain boards port 2 conflicts with another pin

would be perfect for my CR10 s 5 big printer, big screen ...

Hey Chris, I am having an issue I cannot figure out. I have updated the firmware, checked the Baud rate, and Marlin is at 2.0.7.2. BUT my TFT70 wont control my axis. When I go into move axis they jolt but barely move. I can set the axis to 10 and it doesnt hardly move but maybe 1mm. And the z axis wont move at all. Any Ideas?
