# Motorized Camera Slider 2-Axis ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/136/752/medium800/3d_printing_hero-white.jpg?1747058070 ) https://youtu.be/5qv4TInZV0k https://youtube.com/live/7giKCuUSC2M?feature=share ## Slide & Pan This project uses two stepper motors to create smooth cinematic motion for capturing video or timelapse photography. You can use it to automate both trucking and panning for beautiful compound camera motion. It features a 1.3in TFT screen for displaying a user interface and a rotary encoder for controlling the stepper motors.  It's powered by an Adafruit KB2040 running CircuitPython. The TMC2209 stepper motor drivers offer smooth and silent micro stepping.  The software features a mode for capturing timelapses and a one shot mode for filming video. ![](https://cdn-learn.adafruit.com/assets/assets/000/136/767/medium640/3d_printing_hero-unicorn.jpg?1747078288) ## DIY Motorized Slider 3D printed parts support two pieces of aluminum extrusion. A timing belt and pulley wheels are used to slide the carriage along the profile offering about 16 inches (40cm) of travel. A second motor is dedicated for panning offering a bit over 180 degrees. A custom PCB reduces the amount of wiring connecting the microcontroller, TFT display, buck converter and two stepper motor drivers. It runs off a 12V AA battery pack making the build portable for filming outdoors. ![](https://cdn-learn.adafruit.com/assets/assets/000/136/768/medium640/3d_printing_hero-outside.jpg?1747079593) ## Crank It! Use the rotary encoder to set the start and ending positions of the panning motor. A 3D printed rotary handle lets you crank the motor making an intuitive interface for setting the panning stepper motor. ![](https://cdn-learn.adafruit.com/assets/assets/000/136/758/medium640thumb/3d_printing_motor2-loop.jpg?1747069575) Primary: This learn guide assumes prior experience with electronics, 3D printing, mechanical engineering and videography.

It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate. ## CircuitPython Quickstart Follow this step-by-step to quickly get CircuitPython running on your board. [Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_kb2040/) **Click the link above to download the latest CircuitPython UF2 file.** Save it wherever is convenient for you. ![install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/655/medium640/install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg?1618943202) ![](https://cdn-learn.adafruit.com/assets/assets/000/108/852/medium800/adafruit_products_KeeBoar_boot_reset.jpg?1644515196) To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RPI-RP2 drive appears!** If the drive does not appear, release all the buttons, and then repeat the process above. You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button. A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.** You will see a new disk drive appear called **RPI-RP2**.   Drag the **adafruit\_circuitpython\_etc.uf2** file to **RPI-RP2.** ![install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/656/medium640/install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg?1618943666) ![install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/657/medium640/install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg?1618943674) The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear. That's it, you're done! :) ![install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/658/medium640/install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg?1618943864) ## Safe Mode You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help. Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_. Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive. ### Entering Safe Mode To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.) ### In Safe Mode If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times. If you connect to the serial console, you'll find the following message. ```terminal Auto-reload is off. Running in safe mode! Not running saved code. CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode. Press any key to enter the REPL. Use CTRL-D to reload. ``` You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._ ## Flash Resetting UF2 If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RPI-RP2. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython. [Download flash erasing "nuke" UF2](https://cdn-learn.adafruit.com/assets/assets/000/101/659/original/flash_nuke.uf2?1618945856) # Motorized Camera Slider 2-Axis ## Code the Slider Once you've finished setting up your KB2040 with CircuitPython, you can access the code, images, font and necessary libraries by downloading the Project Bundle. To do this, click on the **Download Project Bundle** button in the window below. It will download to your computer as a zipped folder. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/TMC2209_Camera_Slider/CircuitPython/code.py ## Upload the Code and Libraries to the KB2040 After downloading the Project Bundle, plug your KB2040 into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called **CIRCUITPY**. Unzip the folder and copy the following items to the KB2040's **CIRCUITPY** drive. - **lib** folder - **code.py** - **adafruit\_tmc2209.py** - **generic\_uart\_device.py** - **icons.bmp** - **Arial-14.bdf** Your KB2040 **CIRCUITPY** drive should look like this after copying the **lib** folder, image file, font file and the  **Python** files. ![CIRCUITPY drive](https://adafruit.github.io/Adafruit_Learning_System_Guides/TMC2209_Camera_Slider_CircuitPython.png ) ## How the Code Works There are three code files: **adafruit\_tmc2209.py** , **generic\_uart\_device.py** and the main **code.py**. **adafruit\_tmc2209.py** and **generic\_uart\_device.py** are driver files for the TMC2209 UART control. The **code.py** file depends on these files to control the TMC2209 drivers. At the top of **code.py** are some user parameters. `RAILS` is the length of the rails in mm. `microsteps` are the number of microsteps used by the stepper motors. `gear_ratio` is the gear reduction for the camera pan mechanism. Finally, `shot_velocities` contains the one-shot speeds in seconds. ```python RAILS = 520 # length of rails in mm microsteps = 128 gear_ratio = 41 / 16 shot_velocities = [ 20, 15, 10 ] ``` ### Keypad, TFT and Encoder The two end stop switches and the rotary encoder button are instantiated as a `Keypad` object. The TFT is controlled via SPI. The rotary encoder is wired directly to GPIO for `rotaryio`. ```python keys = keypad.Keys((board.D2, board.A2, board.A3), value_when_pressed=False, pull=True) encoder = rotaryio.IncrementalEncoder(board.D7, board.D6) last_position = None spi = board.SPI() tft_cs = board.D10 tft_dc = board.D8 display_bus = FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=board.D9) display = ST7789(display_bus, width=240, height=240, rowstart=80, auto_refresh=False) ``` ### Graphics The icons for the different menu options are on a single bitmap file ( **icons.bmp** ) and are used as a sprite sheet with `TileGrid`. There are two text objects: `title_text` and `text_area` that update depending on the menu. ```python splash = displayio.Group() display.root_group = splash bitmap = displayio.OnDiskBitmap(open("/icons.bmp", "rb")) grid_bg = displayio.TileGrid(bitmap, pixel_shader=bitmap.pixel_shader, tile_height=100, tile_width=100, x=(display.width - 100) // 2, y=(display.height - 100) // 2) splash.append(grid_bg) text_group = displayio.Group() font = bitmap_font.load_font("/Arial-14.bdf") title_text = "Camera Slider" title_area = label.Label(font, text=title_text, color=0xFFFFFF) title_area.anchor_point = (0.5, 0.0) title_area.anchored_position = (display.width / 2, 25) text_group.append(title_area) splash.append(text_group) text_area = label.Label(font, text="", color=0xFFFFFF) text_area.anchor_point = (0.5, 1.0) text_area.anchored_position = (display.width / 2, display.height - 25) text_group.append(text_area) ``` ### TMC2209 UART The two TMC2209 drivers are controlled over UART. Each driver is on its on UART line. Driver 1 uses the default UART ( **RX** and **TX** ) and driver 2 uses the secondary UART ( **D4** and **D5** ). The microsteps are set for each of the drivers, along with a starting direction. ```python uart = busio.UART(tx=board.TX, rx=board.RX, baudrate=115200, timeout=0.1) driver1 = TMC2209(uart=uart, addr=0) driver2 = TMC2209(tx_pin=board.D4, rx_pin=board.D5, addr=0) version1 = driver1.version version2 = driver2.version print(f"TMC2209 #1 Version: 0x{version1:02X}") print(f"TMC2209 #2 Version: 0x{version2:02X}") driver1.microsteps = microsteps print(driver1.microsteps) driver2.microsteps = microsteps print(driver2.microsteps) STEPS_PER_MM = 200 * microsteps / 8 driver1.direction = False driver2.direction = True ``` ### Menu The menu system is the backbone of the project. It is used to navigate through setting up a shot sequence. The TFT displays icons and text that correspond with each menu scene. The `adv_menu()` function takes care of advancing the graphics. ```python titles = ["Camera Slider", "Motor 1", "Motor 2", "Mode", "Timelapse", "One-Shot", "Start?", "Running"] home_text = ["Press to Begin", "0"] motor1_text = ["Slide to Start Point", "0"] motor2_text = ["Move to Start", "Move to End", "0"] mode_text = ["Timelapse", "One-Shot"] time_text = ["1", "5", "10", "15", "30"] shot_text = ["Slow", "Medium", "Fast"] start_text = ["Go!", 0] running_text = ["STOP!", "Pause/Resume"] running_icons = [6, 7] mode_icons = [3, 4] sub_titles = [home_text, motor1_text, motor2_text, mode_text, time_text, shot_text, start_text, running_text] text_area.text = home_text[0] def adv_menu(m): m = (m + 1) % 8 title_area.text = titles[m] sub = sub_titles[m] if m == 4: grid_bg[0] = 3 elif m == 5: grid_bg[0] = 4 elif m > 5: grid_bg[0] = m - 1 else: grid_bg[0] = m text_area.text = sub[0] display.refresh() return m ``` ### Moving the Motors Each driver has a dictionary to track its movement and start/pause/stop state throughout the different movement functions and the main loop. ```python motor1_movement = { "is_active": False, "current_step": 0, "total_steps": 0, "start_pos": 0, "end_pos": 0, "step_direction": 1, "last_step_time": 0, "step_interval": 0, "is_paused": False, "toggle_pause": False, "stop_requested": False } motor2_movement = { "is_active": False, "current_step": 0, "total_steps": 0, "start_pos": 0, "end_pos": 0, "step_direction": 1, "last_step_time": 0, "step_interval": 0, "is_paused": False, "toggle_pause": False, "stop_requested": False } ``` A few functions are used to control the motor movement. Driver 1, which moves the camera along the rails, has its own set of functions since it is moving a much longer distance than driver 2; which pans the camera. Both drivers utilize the velocity calculation from the datasheet: ```python vactual = int(microsteps_per_second / (fCLK / (1 << 24))) vactual = max(-(1 << 23), min((1 << 23) - 1, vactual)) ``` Velocity is used instead of individual steps because its a lot smoother and silent. The functions let you pass the time and number of steps and calculate the velocity from that. Additionally, with the combination of the dictionaries, both motors can be paused/resumed/stopped without blocking in the loop. ### The Loop At the top of the loop, if either of the motors' `["is_active"]` parameter is `True`, it means that they are rotating. `ticks_ms()` is used to keep track of the time.  ```python while True: if motor1_movement["is_active"]: current_time = supervisor.ticks_ms() elapsed = current_time - motor1_movement["movement_start_time"] if elapsed >= motor1_movement["movement_duration_ms"]: driver1.rotate(0) driver1.disable_motor() motor1_movement["is_active"] = False if motor2_movement["is_active"]: current_time = supervisor.ticks_ms() elapsed = current_time - motor2_movement["movement_start_time"] if elapsed >= motor2_movement["movement_duration_ms"]: driver2.rotate(0) driver2.disable_motor() motor2_movement["is_active"] = False ``` `Keypad` events and the rotary encoder are used to navigate the menu system. When the rotary encoder button is pressed (`key_number 0`), the menu advances. It is also used to pause or stop the motors while they are moving through a shot. The end stop switches and rotary encoder have different functionality depending on the menu index. The display is updated with different text if the rotary encoder is used to scroll through options. ```python event = keys.events.get() if event: if event.pressed: print(f"{event.key_number} pressed") if event.key_number == 0: if menu == 0: menu = adv_menu(menu) elif menu == 2: if select == 0: motor2_coordinates[select] = driver2.position if select == 1: motor2_coordinates[select] = driver2.position select += 1 text_area.text = motor2_text[select] if select > 1: select = 0 menu = adv_menu(menu) if motor2_coordinates[0] > motor2_coordinates[1]: move = motor2_coordinates[0] - motor2_coordinates[1] else: move = motor2_coordinates[1] - motor2_coordinates[0] move = -move driver2.step(move) elif menu == 3: if select == 1: timelapse = False menu += 1 select = 0 else: timelapse = True menu = adv_menu(menu) elif menu == 4: menu += 1 time_mode = select menu = adv_menu(menu) select = 0 print(f"{time_text[time_mode]}, timelapse: {timelapse}") elif menu == 5: shot_mode = select menu = adv_menu(menu) select = 0 print(f"{shot_text[shot_mode]}, timelapse: {timelapse}") elif menu == 6: menu = adv_menu(menu) if timelapse: movement_time = int(time_text[time_mode]) * 60 print(f"starting a timelapse for {time_text[time_mode]} minutes") status1 = move_motor_with_rotate( driver1, motor1_movement, start_position=0, end_position=int(RAILS * STEPS_PER_MM), duration_sec=movement_time, microsteps=microsteps ) if abs(motor2_coordinates[1] - motor2_coordinates[0]) > 0: velocity2 = move_steps_over_time(camera_driver=True, start_position=motor2_coordinates[0], end_position=motor2_coordinates[1], time_seconds=movement_time, microsteps=microsteps, ratio=gear_ratio) print(f"driver2 velocity is: {velocity2}") driver2.enable_motor(run_current=25) driver2.rotate(velocity2) motor2_movement["is_active"] = True motor2_movement["start_pos"] = motor2_coordinates[0] motor2_movement["end_pos"] = motor2_coordinates[1] motor2_movement["movement_start_time"] = supervisor.ticks_ms() motor2_movement["movement_duration_ms"] = movement_time * 1000 motor2_movement["velocity"] = velocity2 motor2_movement["total_steps"] = (abs(motor2_coordinates[1] - motor2_coordinates[0])) else: print(f"starting a {shot_text[shot_mode]} one-shot") movement_time = shot_velocities[shot_mode] status1 = move_motor_with_rotate( driver1, motor1_movement, start_position=0, end_position=int(RAILS * STEPS_PER_MM), duration_sec=movement_time, microsteps=microsteps ) if abs(motor2_coordinates[1] - motor2_coordinates[0]) > 0: velocity2 = move_steps_over_time(camera_driver=True, start_position=motor2_coordinates[0], end_position=motor2_coordinates[1], time_seconds=movement_time, microsteps=microsteps, ratio=gear_ratio) driver2.enable_motor(run_current=25) driver2.rotate(velocity2) motor2_movement["is_active"] = True motor2_movement["start_pos"] = motor2_coordinates[0] motor2_movement["end_pos"] = motor2_coordinates[1] motor2_movement["movement_start_time"] = supervisor.ticks_ms() motor2_movement["movement_duration_ms"] = movement_time * 1000 motor2_movement["velocity"] = velocity2 motor2_movement["total_steps"] = (abs(motor2_coordinates[1] - motor2_coordinates[0])) elif menu == 7: if select == 0: stop_all_motors() text_area.text = "Stopping..." menu = adv_menu(menu) elif select == 1: pause_resume_motor1() pause_resume_motor2() paused_state = motor1_movement["is_paused"] or motor2_movement["is_paused"] text_area.text = "Paused" if paused_state else "Running" display.refresh() if event.key_number == 1: if menu == 1: driver1.direction = False driver1.reset_position() menu = adv_menu(menu) elif menu == 7: stop_all_motors() menu = adv_menu(menu) if event.key_number == 2: if menu == 1: driver1.direction = True driver1.reset_position() menu = adv_menu(menu) elif menu == 7: stop_all_motors() menu = adv_menu(menu) display.refresh() pos = encoder.position if pos != last_pos: if pos > last_pos: if menu == 2: driver2.step(-10) if menu == 3: select = (select + 1) % 2 text_area.text = mode_text[select] grid_bg[0] = mode_icons[select] if menu == 4: select = (select + 1) % len(time_text) text_area.text = time_text[select] if menu == 5: select = (select + 1) % len(shot_text) text_area.text = shot_text[select] if menu == 7: select = (select + 1) % len(running_text) text_area.text = running_text[select] grid_bg[0] = running_icons[select] else: if menu == 2: driver2.step(10) if menu == 3: select = (select - 1) % 2 text_area.text = mode_text[select] grid_bg[0] = mode_icons[select] if menu == 4: select = (select - 1) % len(time_text) text_area.text = time_text[select] if menu == 5: select = (select - 1) % len(shot_text) text_area.text = shot_text[select] if menu == 7: select = (select - 1) % len(running_text) text_area.text = running_text[select] grid_bg[0] = running_icons[select] last_pos = pos display.refresh() ``` # Motorized Camera Slider 2-Axis ## PCB Assembly ## PCB Parts Gather up the components that will be soldered to the PCB.
