marlin tft display brands

I was rebuilding one of my 3D printers — again — and decided I needed a display upgrade. A color screen is nice, but there are some limitations. I also found there are ways around these limitations, so I wanted to share my thoughts on a dual-mode color touch screen LCD controller for your 3D printer. The screen in question is a TFT35 from BigTree Tech. It is similar to an MKS screen, but it can operate in two different modes, as you will see.

A few years ago, I picked up an Anet A8 which was very inexpensive, especially on sale. Not the best printer, though, because it has that cheap acrylic frame. No problem. A box full of aluminum extrusion later, the printer was reborn. Over time, I’ve completely reworked the extrusion system and the Y-axis, leaving only the motors, bearings, and the controller/display as the original.

I happened to have one of these lying around so when I installed a new motherboard — a Fysetc Spider if you are curious — I also wired in the new LCD. I had to recompile Marlin, of course, but that’s easy. It all worked, it just looked a little bland.

There’s another way to control a printer, and it’s one you may have thought of before. Since the printer accepts commands via a serial port, you could take a computer like a Raspberry Pi with a nice LCD and just have it issue commands to the serial port. Bonus points if the board has more than one serial port so you can still hook up a PC or a Raspberry Pi running Octoprint or similar. Turns out, you don’t have to build this. The MKS touchscreen uses an ARM chip (it isn’t a Pi, though) and has a touch screen that you can use to control the printer. These come in different sizes and are usually called something like TFT35 for 3.5 inch display.

The advantage isn’t just appearance. Having a bunch of touch screen buttons makes many things easier. For example, if the printer is at (0,0) and you want to jog the head to (100,200), that ends up being a lot of button pushes in Marlin. With the touch display, you can bring up a navigation screen that makes it easy. Or, you can bring up an entire terminal and enter G-code. When you press Send, it shows the results of the command, if any. You can set a temperature with the knob, on-screen buttons, or press the number and type in what you want with a virtual keypad.

These displays are colorful and nice, but there are a few things they can’t do. Marlin has some wizards and user interaction that insist on a proper, local LCD. But the Marlin code thinks the MKS display is a remote host computer, connected over serial. Displays that can act like both types of LCDs are a sweet hack, and here’s the part that was never clear to me before: these displays can switch modes during printer operation. In other words, it is not a case of selecting a mode and rebooting everything. You can be looking at the colorful touchscreen, then switch over to the stock display while printing and then switch back any time you want. The best of both worlds.

On the face of it, the display looks like an MKS TFT. You have colorful menus and a touch screen. The connection for that is a simple two-wire serial port, along with — of course — power, ground, and an optional reset connection. They provide a cable you can use or modify to connect to your setup. There is also an EXT3 port for boards that have that connector.

If all you want is an MKS display, you are done. Since the display looks like a host computer, you don’t even have to recompile Marlin if the serial port you used was active. In my case, the second serial port wasn’t set up, so I had to recompile, but I do that often enough, anyway.

However, if you wire the normal EXT1 and EXT2 ribbon cables to your printer, the display can emulate a normal 128×64 LCD. If you are already set up to use one of these displays, you should not need to recompile Marlin to use this display. However, if you are set up for a different type of display, you’ll need to tell Marlin to use the normal “REPRAP DISCOUNT GRAPHICS CONTROLLER.”

Here’s what I never understood about the device. Looking at the write-up about it on different vendor sites like Amazon, Banggood, or AliExpress, it sounded like you could use the screen in either mode as a static configuration choice. In other words, you might wire up EXT1 and EXT2 and then use the emulated mode until you decided to switch over to serial at some future date. But that’s not how it works. You can connect all the cables and switch back and forth between display systems on the fly.

That’s huge. It means you can have a nice user interface that lets you control the printer, print from an SD card or USB stick, and even make customizations to the menu with the source code provided on GitHub or with a simple configuration file edit. (And, yes, you can add custom menu items simply.) But when you need to do something very specific to Marlin, or a new feature shows up that the LCD doesn’t know about yet, you can simply switch to the Marlin display mode. Then you can switch back.

The process to switch is simple. Just hold down the encoder knob or push the screen for a few seconds. A screen will show up allowing you to pick the Marlin mode or the BTT mode. Just touch the one you want. In Marlin mode, the touchscreen does nothing except switch modes, so you might want to use that method. If you hold the encoder down in Marlin mode, the printer will also see the repeated enter keys until the LCD pops up the selection screen.

Installing the LCD was straightforward save a few problems. For some reason, the pin 1 designation for EXP1 and EXP2 are not consistent among vendors. A Geeetech display worked fine with the Spider board, but the TFT35 didn’t want to come up in Marlin mode at all. I applied power at the serial port and the board appeared hung. The answer was to snip off the alignment tabs on the ribbon cables and flip them 180 degrees.

The serial port was also a mystery. With so little documentation on anything, I just soldered the power and ground wires and then hand twisted RX and TX so I could swap them until it worked. As I expected, the cable needed a cross on those lines to work. You also have to match the display’s baud rate to the port you are using.

After that, it all worked fine. The EXP1 and EXP2 connectors do connect to the board’s reset, so you don’t need to wire the serial port’s reset pin if you have those connected. However, I did notice that switching the mainboard to DFU mode will sometimes fail with the display plugged in. Reflashing the display requires an SD card that flashes a binary file and then reboots and loads fonts and icons. If it is connected to the Spider, it sometimes hangs when trying to reboot during an update. It also works sometimes, though, so I suspect it is just loading on the reset line. In any event, popping the connectors will make it work if you don’t want to try repeatedly.

The display has a number of other ports, but you probably shouldn’t use them. For example, there’s a port for a filament runout sensor. But if you connect it there, it will only work if you are printing using an SD card or USB stick in the display. A better option is to connect it to your printer and tell Marlin to notify the host if a filament break occurs. This will work with the display or something like Octoprint.

In theory, you should be able to connect Octoprint itself through one of the extra serial ports. However, I never got this to fully work. The subordinate port seems to work pretty well, but it never sends Octoprint acknowledgments so Octoprint waits forever or until you force it to continue — use the Fake Acknowledgment button in the terminal. Since the Spider has multiple serial ports, it isn’t a big deal, but in theory, the TFT should work a little better if it can intercept and filter the data stream between the printer and the host software. In practice, I don’t really notice any problems. Some Octoprint plugins like DisplayLayer can send status information to the TFT, anyway.

The truth is, I don’t switch over to Marlin mode very often, but it is nice to have it if I want it, and you can even change the colors to suit you. I really wanted the passthrough mode to work but couldn’t figure out what was going on without digging into the source code, and that might be a project for another day.

Another note: Using the jog keys sets the printer to relative mode. If you are used to popping codes into a terminal, you might want to get used to issuing a G90 before you send a move because the TFT will change it to relative anytime you do a jog.

These displays are inexpensive and easy to interface and since they can still work as a classic display, there’s no reason not to do this easy upgrade. There are plenty of mounting options you can print, of course. The finished result looks great and doing things like moving in both X and Y are much easier with the new display.

Up front, I need to say that in the end this turned out to be a nice display with all the functions and features I had hoped for, and it works quite well! Now I"ll tell you about the adventure to end up there... lol

That was all on a Ender-3 that has a SKR 1.3 board in it running the latest stable Marlin 2.0 firmware. I have another machine here that"s got a KFB3.0 board running Marlin 1.1.9, which I updated to 2.0 (to have support for using two serial ports) and attempted to set that board up with the TFT screen on the AUX-1 (serial) header. It still refused to connect, same issues as before. At this point I decided the board must simply have a bad UART on it. I was tempted to remap some pins and compile its firmware to use one of the spare UARTs on the board, but decided to just return it to Amazon and get another one.

Third screen arrived, late, but intact. This time around I had it plugged into the SKR board and set up in Marlin, it was working inside of 15 minutes. Much better. :D At that point I set out to update the screen"s firmware to get the latest features/fixes and the material theme you see in the pictures. It would have been fairly simple had there been better documentation (there"s next to none!) but I was able to figure it out. It"s actually quite simple once you know how to sort through the files on the github and assemble what you need in the proper folder structure. So here"s a few tips that may help someone else along the way...

UNcomment "#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER" and comment any other display you might have been using before. This is the get the 12864 emulation working. Plug in EXP1 and EXP2 cables

In configuration_adv.h, set "#define SDCARD_CONNECTION ONBOARD". This will allow the SKR 1.3 to read from it"s own micro SD card slot, using the normal Marlin menus as before. The TFT screen will also be able to read from this card slot using the "onboard" option on the screen. You can also use the TFT screen to read it"s full size SD card slot, or the USB port as needed and print from those as well.

When updating the screen"s firmware, place the proper bin file on the root of a full size SD card and place it in the screen"s card slot. (currently the newest is BIGTREE_TFT35_V3.0.25.bin) You"ll also need the font and icon files to match, or things will get all jumbled around on screen and not display properly. It wasn"t clear, but to get those updated, you need those in a file structure like - root>TFT35>bmp>icon files in this folder, and root>TFT35>font>font files in this folder.

Alter Marlin firmware to send queue in binary from to smart screen. If I recall correctly queue buffer size is 8K, so it is not a big deal even for UART.

Develop brand new firmware for smart screen that will use these data to draw picture on TFT screen (might reuse existing Marlin code for this). Some smart screens will need software FSMC impelentation (like 2.4" with STM32F103RC MCU)

Marlin is a huge C++ program composed of many files, but here we’ll only be talking about the two files that contain all of Marlin’s compile-time configuration options: Configuration.h contains the core settings for the hardware, language and controller selection, and settings for the most common features and components.

The two .h files contain all of Marlin’s build-time configuration options. Simply edit or replace these files, then build and upload Marlin to the board. Hundreds of user-donated configurations are posted at the Configurations repository to get you started.

Marlin is configured using C++ compiler directives. This allows Marlin to leverage the C++ preprocessor and include only the code and data needed for the enabled options. This results in the smallest possible binary. A build of Marlin can range from 50K to over 230K in size.

To use configurations from an earlier version of Marlin, first try dropping them into the newer Marlin, updating CONFIGURATION_H_VERSION and CONFIGURATION_ADV_H_VERSION, and building the firmware. As part of the build process, Marlin’s sanity-checking prints out helpful error messages explaining what needs to change.

The core and default settings of Marlin live in the Configuration.h file. Most of these settings are fixed. Once you compile Marlin, that’s it. To change them you need to re-compile. However, several items in Configuration.h only provide defaults -factory settings- that can be changed via the user interface, stored on EEPROM and reloaded or restored to initial values.

Marlin now checks for a configuration version and won’t compile without this setting. If you want to upgrade from an earlier version of Marlin, add this line to your old configuration file. During compilation, Marlin will throw errors explaining what needs to be changed.

#define CUSTOM_STATUS_SCREEN_IMAGE STRING_CONFIG_H_AUTHOR is shown in the Marlin startup message to identify the author (and optional variant) of the firmware. Use this setting as a way to uniquely identify your custom configurations. The startup message is printed whenever the board (re)boots.

The most important setting is Marlin is the motherboard. The firmware needs to know what board it will be running on so it can assign the right functions to all pins and take advantage of the full capabilities of the board. Setting this incorrectly will lead to unpredictable results.

This is the name of your printer as displayed on the LCD and by M115. For example, if you set this to “My Delta” the LCD will display “My Delta ready” when the printer starts up.

This value, from 0 to 6, defines how many extruders (or E steppers) the printer has. By default Marlin will assume separate nozzles all moving together on a single carriage. If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below.

This value is used by Marlin to compensate for Filament Width when printing in volumetric mode (See M200), and by the Unified Bed Leveling command G26 when printing a test grid.

The listing above these options in Configuration.h contains all the thermistors and thermocouples that Marlin knows and supports. Try to match your brand and model with one of the sensors in the list. If no match is found, use a profile for a similar sensor of the same brand, or try “1” – the generic profile. Each profile is calibrated for a particular temperature sensor so it’s important to be as precise as possible.

Enable this option to use sensor 1 as a redundant sensor for sensor 0. This is an advanced way to protect against temp sensor failure. If the temperature difference between sensors exceeds MAX_REDUNDANT_TEMP_SENSOR_DIFF Marlin will abort the print and disable the heater.

Maximum temperature for each temperature sensor. If Marlin reads a temperature above these values, it will immediately shut down for safety reasons. For the E3D V6 hotend, many use 285 as a maximum value.

Marlin uses PID (Proportional, Integral, Derivative) control (Wikipedia) to stabilize the dynamic heating system for the hotends and bed. When PID values are set correctly, heaters reach their target temperatures faster, maintain temperature better, and experience less wear over time.

Thermal protection is one of the most vital safety features in Marlin, allowing the firmware to catch a bad situation and shut down heaters before it goes too far. Consider what happens when a thermistor comes loose during printing. The firmware sees a low temperature reading so it keeps the heat on. As long as the temperature reading is low, the hotend will continue to heat up indefinitely, leading to smoke, oozing, a ruined print, and possibly even fire.

Marlin offers two levels of thermal protection: Check that the temperature is actually increasing when a heater is on. If the temperature fails to rise enough within a certain time period (by default, 2 degrees in 20 seconds), the machine will shut down with a “Heating failed” error. This will detect a disconnected, loose, or misconfigured thermistor, or a disconnected heater.

Marlin supports four kinematic motion systems: Cartesian, Core (H-Bot), Delta, and SCARA. Cartesian is the simplest, applying each stepper directly to an axis. CoreXY uses a special belt arrangement to do XY motion, requiring a little extra maths. Delta robots convert the motion of three vertical carriages into XYZ motion in an “effector” attached to the carriages by six arms. SCARA robots move an arm in the XY plane using two angular joints.

These settings allow Marlin to tune stepper driver timing and enable advanced options for stepper drivers that support them. You may also override timing options in Configuration_adv.h.

In print/travel moves, DEFAULT_ACCELERATION and DEFAULT_TRAVEL_ACCELERATION apply to the XYZ axes. In retraction moves, DEFAULT_RETRACT_ACCELERATION applies only to the E-axis. During movement planning, Marlin constrains the default accelerations to the maximum acceleration of all axes involved in the move.

Use this option if you’ve connected the probe to a pin other than the Z MIN endstop pin. With this option enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your board’s pins file (usually the X or Z MAX endstop pin since these are the most likely to be unused). If you need to use a different pin, define your custom pin number for Z_MIN_PROBE_PIN in Configuration.h.

With Marlin you can directly specify the bed size. This allows Marlin to do extra logic related to the bed size when it differs from the movement limits below. If the XY carriage is able to move outside of the bed, you can specify a wider range below.

With this feature, a mechanical or opto endstop switch is used to check for the presence of filament in the feeder (usually the switch is closed when filament is present). If the filament runs out, Marlin will run the specified G-code script (by default M600).

If you have SRAM to spare, this option will multiply the resolution of the bilinear grid using the Catmull-Rom subdivision method. This option only applies to bilinear leveling. If the default value of 3 is too expensive, try 2 or 1. (In Marlin 1.1.1, the default grid will be stored in PROGMEM, as UBL now does.)

Commands like M92 only change the settings in volatile memory, and these settings are lost when the machine is powered off. With this option enabled, Marlin uses the built-in EEPROM to preserve settings across reboots. Settings saved to EEPROM (with M500) are loaded automatically whenever the machine restarts (and in most setups, when connecting to a host), overriding the defaults set in the configuration files. This option is highly recommended, as it makes configurations easier to manage.

When Host Keepalive is enabled Marlin will send a busy status message to the host every couple of seconds when it can’t accept commands. Disable if your host doesn’t like keepalive messages. Use DEFAULT_KEEPALIVE_INTERVAL for the default number of seconds between “busy” messages. Override with M113. Marlin 1.1.5 and up include the BUSY_WHILE_HEATING option for hosts that treat host keepalive as a strict busy protocol.

This option applies only to character-based displays. Character-based displays (based on the Hitachi HD44780) provide an ASCII character set plus one of the following language extensions: JAPANESE … the most common

Disable all menus and only display the Status Screen with NO_LCD_MENUS, or just remove some extraneous menu items to recover space with SLIM_LCD_MENUS.

Marlin includes support for several controllers. The two most popular controllers supported by Marlin are: REPRAP_DISCOUNT_SMART_CONTROLLER A 20 x 4 character-based LCD controller with click-wheel.

REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER A monochrome 128 x 64 pixel-based LCD controller with click-wheel. Able to display simple bitmap graphics and up to 5 lines of text.

Temperature status LEDs that display the hotend and bed temperature. If all hotend and bed temperature set-point are < 54C then the BLUE led is on. Otherwise the RED led is on. There is 1C hysteresis.

Marlin includes support for the Baricuda Extruder for 3D Printing Sugar and Chocolate also hosted on GitHub. The feature adds the codes M126, M127, M128, and M129 for controlling the pump and valve of the Baricuda.

Marlin currently supplies two options for RGB-addressable color indicators. In both cases the color is set using M150 Rr Ug Bb to specify RGB components from 0 to 255.

#define NEOPIXEL_PIXELS 30 // Number of LEDs in the strip, larger of 2 strips if 2 NeoPixel strips are used #define NEOPIXEL_IS_SEQUENTIAL // Sequential display for temperature change - LED by LED. Disable to change all LEDs at once. #define NEOPIXEL_BRIGHTNESS 127 // Initial brightness (0-255) //#define NEOPIXEL_STARTUP_TEST // Cycle through colors at startup

To solve this issue, this option sets the number of milliseconds a hotend will preheat before Marlin starts to check the temperature. Set a delay sufficient to reach a temperature your sensor can reliably read. Lower values are better and safer. If you require a value over 30000, this could indicate a problem.

#if EITHER(ULTIPANEL, EXTENSIBLE_UI) #define MANUAL_FEEDRATE { 50*60, 50*60, 4*60, 60 } // Feedrates for manual moves along X, Y, Z, E from panel #define SHORT_MANUAL_Z_MOVE 0.025 // (mm) Smallest manual Z move (< 0.1mm) #if ENABLED(ULTIPANEL) #define MANUAL_E_MOVES_RELATIVE // Display extruder move distance rather than "position" #define ULTIPANEL_FEEDMULTIPLY // Encoder sets the feedrate multiplier on the Status Screen #endif

#if ENABLED(LED_CONTROL_MENU) #define LED_COLOR_PRESETS // Enable the Preset Color menu option #if ENABLED(LED_COLOR_PRESETS) #define LED_USER_PRESET_RED 255 // User defined RED value #define LED_USER_PRESET_GREEN 128 // User defined GREEN value #define LED_USER_PRESET_BLUE 0 // User defined BLUE value #define LED_USER_PRESET_WHITE 255 // User defined WHITE value #define LED_USER_PRESET_BRIGHTNESS 255 // User defined intensity //#define LED_USER_PRESET_STARTUP // Have the printer display the user preset color on startup

Use the optimizations here to improve printing performance, which can be adversely affected by graphical display drawing, especially when doing several short moves, and when printing on DELTA and SCARA machines.

Some of these options may result in the display lagging behind controller events, as there is a trade-off between reliable printing performance versus fast display updates.

This feature allows Marlin to use linear pressure control for print extrusion, to eliminate ooze, improve corners, etc. See Configuration_adv.h and the Linear Advance page for more complete documentation.

Some hosts use a proportional font in their output console. This makes it hard to read output from Marlin that relies on fixed-width for alignment. This option tells Marlin how many spaces are required to fill up a typical character space in the host font. For clients that use a fixed-width font (like OctoPrint), leave this set to 1.0. Otherwise, adjust according to your host.

Experimental feature for filament change support and parking the nozzle when paused. Adds the M600 command to perform a filament change. With PARK_HEAD_ON_PAUSE enabled also adds the M115 command to pause printing and park the nozzle. Requires an LCD display. Note that M600 is required for the default FILAMENT_RUNOUT_SCRIPT. Requires LCD display and NOZZLE_PARK_FEATURE.

You’ll need to import the L6470 library into the Arduino IDE for this. See Configuration_adv.h for the full set of sub-options. NOTE: Support for L6470 was removed from Marlin in version 2.1, but may be restored in a future version if there is some demand.

This feature can be used to talk to slave devices on the i2c bus, passing data back to the host. With additional work the TWIBus class can be used to build a full protocol and add remote control features to Marlin, distributing load over two or more boards.

SuperPid is a router/spindle speed controller used in the CNC milling community. Marlin can be used to turn the spindle on and off. It can also be used to set the spindle speed from 5,000 to 30,000 RPM.

Enable to add support for a filament width sensor such as Filament Width Sensor Prototype Version 3. With a filament sensor installed, Marlin can adjust the flow rate according to the measured filament width. Adjust the sub-options below according to your setup.

It is recommended to enable this feature (along with EXTENDED_CAPABILITIES_REPORT) to install the M155 Auto-Report Temperature command. M115 tells Marlin to send the current temperature to the host at regular intervals, instead of requiring the host software to send M105 repeatedly. This saves a space in the command buffer and reduces overhead.

Enable this option for a leaner build of Marlin that removes all workspace offsets. This simplifies all coordinate transformations, leveling, etc., and may allow for slightly faster printing. With this option, M206 and M428 are disabled, and G92 reverts to its old behavior, as it is in Marlin 1.0.

#define MAX7219_INIT_TEST 2 // Test pattern at startup: 0=none, 1=sweep, 2=spiral #define MAX7219_NUMBER_UNITS 1 // Number of Max7219 units in chain. #define MAX7219_ROTATE 0 // Rotate the display clockwise (in multiples of +/- 90°) // connector at: right=0 bottom=-90 top=90 left=180

On a board with a ATmega2560/1280 micro-controller you have three potential serial ports to use for the MMU2: serial 1 (pins 18/19), serial 2 (pins 16/17), serial 3 (pins 14/15). Define the port your MMU2 is connected to - this activates an additional serial connection in Marlin named (in the example configuration) internalSerial.

The MMU2 LCD menu allows you to load filament to the nozzle. The MMU2 will transport the filament all the way to the extruder gears. The required extruder steps to load it into the hotend have to be defined in Marlin.
