Dear reader,

First of:
Don't post any comment except a FAQ with an answer.
OR: if something is wrong in the FAQ or an addition to what's already written.

I'll reply to this comment. Please remove it when I did this to keep the comment section clean

That said:
I made this FAQ, Frequently Asked Question, because a lot of questions are asked a lot lately.
In this FAQ I, and other users underneath, will post a question with a answer to it.
Pleas check ALL FAQ's before posting a issue.

FAQ

When posting a FAQ underneath, please use the same style ;-)

Q: The print speed changes when I turn the rotary encoder

Answer: This happened because the encoder is hardwired to marlin.
For some more details see: #915 (comment) , #680, #757

Q: Switching to Marlin mode is giving me a empty screen

Answer: First, check your ribbon cable connections to the TFT screen.

A: In case your TFT does not have an EXP connector at all (TFT28 for example), you can not use the Marlin emulator mode.

B: In case your mainboard provides EXP1 and EXP2, you have to connect 2 ribbon cables connecting EXP1 and EXP2 of the mainboard to EXP1 and EXP2 of the TFT. In the Marlin firmware of your mainboard, make sure that ONLY the "REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER" is activated in Configuration.h and that all other controllers (especially the "CR10_STOCKDISPLAY") are Deactivated.

C: In case you have a "E3" mainboard, which provides a single EXP connector, you have to connect 1 ribbon cable connecting EXP of the mainboard to EXP3 of the TFT. In the Marlin firmware of your mainboard, make sure that ONLY the "CR10_STOCKDISPLAY" is activated in Configuration.h and that all other controllers (especially the "REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER") are Deactivated.

Q: Touchscreen doesn’t respond/ stay’s in the “Choose mode” selection

Answer: There are 2 possible problems that can be causing this.
a) The screen stay's in choose mode
The screen is touching the frame where it’s mounted in.
Create more clearance in between the touchscreen and the frame where you mounted it.

b) The screen doesn't respond to any touch
The touchscreen settings could be corrupted. The screen doesn't know at this moment how to correctly respond to a touch.
A way to solve this:
Place a text file reset.txt in the root of a SD-card and insert this in the screen
Reset the screen.
When the screen is booted there will be a touchscreen callibration screen. Calibrate the screen and it should be solved.

Q: can't update the firmware of my tft35 V2.0

Answer: there is a bug in the bootloader on your screen. You should update this.
See this for more information and the new bootloader: https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/tree/master/Bootloaders/TFT35_V2%20Bootloader%20fix

Q: scrambled icons and/ or fonts after firmware update

Answer: when you update you're firmware you always should check if there are also changes to the TFTxx folder (where xx stands for screen size). When these are new you should also upload this folder to your TFT screen.
When updating the firmware it's always a good idea to update your config.ini. this will prevent unexpected behaviour.

Q: Filament sensor triggers with filament when filament is inserted

Answer: When you connect the filament-sensor to the TFT screen and you’ve got the message “No filament” on you’re screen it could be that you need to invert the filament sensor. To do this you should got to Menu –> Settings –> feature and search for invert filament sensor. Toggle this one. It should be solved and be working correctly

Q: Unexpected freezes when entering a menu after newly compiled firmware

Answer: Did you also update the config.ini on you're screen after the update? For example the freezing in preheat menu is caused by using a old config.ini.
Please try if this work. When it didn't work place an issue and tell that you did update config.ini ;-)

Q: I received the error “Fade height off". What does it mean and what to do?

Answer: Fade height is a setting for auto bed level. This message will appear when you configured auto bed levelling on your printer.
The reason you receive this message is because you didn’t setup the fade height. Fade height is made too smoothen the bed level mesh.
Set this to 1 or higher to get rid of this error

Q: How to preview 3D-models on the TFT-screen

Answer: For previewing the 3D model on the TFT screen there are some things you should do:

1. Install the Cura plugin: https://github.com/bigtreetech/Bigtree3DPlugin
   --> Please read the readme on this github page!
2. Transfer the generated gcode to your sd-card or pendrive.
3. Make sure that the file-list settings is set to false in the feature menu
4. insert your sd-card or pendrive
5. In the print menu you can see the 3Dpreview for your gcode:
   
   When printing it's displayed on the bottom half of the screen.

Note: To use this option you need the newest version of the TFT firmware!

Manual

I'm currently working on a manual. I will put information in there about GIT, compiling/ building and more.
I try to make it easy to read with no too much text. (I hope you can appreciate it ;-) )
I've added the same FAQ in there too.
You can find it here: https://github.com/traffic-light/manual_nogoodnameyet/blob/master/EN_manual.pdf
It's not done yet. In the next version chapter 1 will be completed.

[traffic-light]

Motion for me:

• Remove the word faq in post
• Make section with known bugs
• Make section with faq
• Add "printer not connected" to the faq (check cables, serial ports and correct orientation of black ribbon cable)

For some more details see: #915 (comment) , #680, #757

@traffic-light Please correct the error description.

Guruathwal has created a fix to address this issue.
the condition is a new FW Marlin and connection via connectors EXP1 and EXP2
For connection via EXP3, adjustment does not work.

I have an idea how to apply Guruathwal correction also for deskz with EXP3 connector (for example SKR mini E3).
It means a small modification of Marlin and the connection of one wire.

Thank you for notifying me. Forgot it there was a fix for 2 wired marlin mode.

Wil update it soon
