Here’s a concise, useful paper-style guide for installing firmware on the QIDI X-Plus (original model, not X-Plus 3 unless specified).

The Ultimate Guide to QIDI X-Plus Firmware Installation: Step-by-Step

If you own a QIDI Tech X-Plus, you already know it’s a workhorse in the professional desktop 3D printing space. However, to keep it printing at peak performance—whether you’re using PLA, ABS, or advanced nylons—keeping the firmware up to date is not just recommended; it’s essential. A successful qidi xplus firmware install can unlock new features, fix thermal runaway bugs, improve bed leveling accuracy, and expand material compatibility.

Yet, unlike simply updating an app on your phone, flashing firmware on the X-Plus requires precision. A mistake can lead to a "bricked" motherboard. Do not worry. This guide will walk you through every single step, from identifying your current version to performing the final calibration.

Step 5: Post-Installation Configuration (Don't Skip This)

After a successful qidi xplus firmware install, the printer resets to factory defaults. Your old EEPROM settings are gone. You must reconfigure:

  1. Thermal calibration: Go to Tool -> Calibration -> PID Autotune. Run this for both the nozzle (240°C) and the heated bed (70°C).
  2. Z-Offset & Leveling: The Z-stop position shifts after an update. Re-level the four corners using the paper test.
  3. Filament Settings: Re-select your material type (ABS, PLA, PETG) because the thermal profiles have been reset.

Step 3: Initiate the Flash

  1. Turn off the printer using the power switch.
  2. Insert the SD card into the slot on the control box.
  3. Turn the printer on.
  4. Watch the Screen:
    • The boot logo will appear.
    • The screen may flash or turn off for a moment.
    • The progress bar will move slowly. This indicates the firmware is writing to the board.
  5. Completion: Once the process is finished, the printer will boot to the main menu.

Qidi X-Plus Firmware Install

The Qidi X-Plus is a versatile consumer 3D printer known for its enclosed build chamber, dual-extruder capability (on some models via upgrade), and ease of use. Like many hobbyist printers, it occasionally benefits from firmware updates to fix bugs, improve print quality, add features, or support new hardware. This essay explains the reasons for installing custom or official firmware on the Qidi X-Plus, outlines preparations and required materials, presents a clear step-by-step installation procedure (covering both official updates and common custom-firmware approaches), discusses post-installation checks and troubleshooting, and assesses risks and best practices. The goal is to give an informed, practical guide so an owner can decide whether to update firmware and, if so, perform the installation safely and effectively.

Why update firmware

  • Bug fixes and stability: Manufacturers periodically release firmware updates that address crashes, heating control issues, or incorrect sensor readings. Installing these can improve reliability.
  • New features and improvements: Firmware updates may add features such as improved thermal protection, better bed leveling routines, filament runout detection, or optimized motion control settings for smoother prints.
  • Hardware support: If you install upgrades (e.g., new hotend, BLTouch/mesh bed-leveling probe, different stepper drivers), updated firmware may be necessary to enable correct operation.
  • Customization and control: Advanced users often install community firmware (e.g., a tailored Marlin build) to gain greater control over acceleration, jerk, thermal settings, additional safety checks, or custom G-code macros.

Preparations and required materials

  • Determine model and board: Confirm the exact Qidi X-Plus revision and its mainboard model. Different board revisions use different firmware file formats and flashing methods. This information is usually in the user manual, on a sticker on the board, or on the printer’s “About”/firmware screen.
  • Choose firmware source:
    • Official firmware: Download from Qidi’s support site or the official product page. Official releases preserve OEM features such as the touchscreen interface and proprietary controls.
    • Custom firmware: Many community users build Marlin or other open-source firmware configured for Qidi hardware to enable advanced features. Ensure you use a configuration that matches your board, thermistors, stepper wiring, endstops, and any added hardware.
  • Backup current settings: Record or photograph current firmware settings (e.g., current PID values, steps/mm, acceleration, Z-offset, flow multipliers) and copy any custom macros or start/stop G-code. Some printers allow exporting settings to an SD card; otherwise, note them manually.
  • Tools and supplies:
    • A reliable microSD card (or the card supplied with the printer) formatted FAT32.
    • USB cable if flashing via a computer is required.
    • A computer with the required flashing software/drivers (e.g., Cura, Qidi software, or avrdude/STM32 utilities depending on the board).
    • Basic tools to access the controller board (screwdrivers, flashlight).
    • Multimeter (optional) to check connectors or voltages if troubleshooting.
  • Safety precautions: Work with the printer powered off when opening the enclosure. Avoid shorting connectors. If flashing requires powering the printer on, keep hands clear of heated components and moving parts.

Installation methods overview There are two common approaches to updating Qidi X-Plus firmware: qidi xplus firmware install

  1. Official firmware update via SD card or the printer’s UI — typically the safest and simplest route.
  2. Custom firmware flashing (Marlin or similar) via SD card or direct USB/serial connection — allows advanced features but carries higher risk and may void warranty.

Step-by-step: Official firmware via SD card (typical procedure)

  1. Obtain the correct firmware file: Download the official firmware package for the Qidi X-Plus model/revision from the manufacturer’s support page. Verify the file name and any included instructions.
  2. Prepare the SD card: Format a small-capacity microSD card to FAT32. Copy the firmware file (often named with .bin, .hex, or a manufacturer-specific extension) to the root directory of the SD card. Some models require a specific filename — follow the manufacturer’s naming instructions exactly.
  3. Power off the printer: Turn the printer off and insert the SD card into the printer’s card slot.
  4. Initiate update: Power on the printer while the SD card is inserted. The printer usually detects the firmware file and prompts to install automatically, or it may start flashing on boot. Follow any on-screen prompts.
  5. Wait and do not interrupt: Let the update complete. Interrupting a firmware write can brick the controller. When the process finishes, the printer will typically reboot.
  6. Verify: Check the firmware version in the printer’s About or Settings menu. Confirm touchscreen responsiveness and basic functions (axis movement, temperature reading).
  7. Restore settings: Reapply calibrated values (PID, steps/mm, Z-offset) if the update reset them.

Step-by-step: Custom firmware (Marlin) via SD card / binary flash Note: Exact details depend on your mainboard MCU (e.g., STM32, ATmega) and bootloader presence. Many Qidi boards use an STM32 MCU and require either a specially built .bin placed on SD card or flashing via USB/DFU or ST-Link.

  1. Identify board MCU and bootloader: Inspect the board label or consult community threads to determine whether it accepts SD-based bootloader updates, USB/DFU, or needs an SWD programmer.
  2. Obtain or build firmware:
    • Option A — Prebuilt binary: Use a community-provided binary specifically for your board and Qidi X-Plus hardware. Only use binaries known to match your exact board revision and hardware configuration.
    • Option B — Build from source: Clone Marlin (or chosen firmware), configure Configuration.h and Configuration_adv.h for X-Plus specifics: board type, thermistor table, steps/mm, endstop logic, bed size, filament sensor, BLTouch if installed, EEPROM settings, and safety limits. Compile using PlatformIO in Visual Studio Code or the Arduino IDE (if supported).
  3. Flashing method:
    • SD-bootloader method: Some boards accept a firmware.bin on the microSD card in the root directory and flash it on boot. Copy the compiled .bin (with the exact required filename) onto the SD card, insert it, and power on the printer to trigger flashing.
    • DFU/USB method: For STM32 boards with DFU, use dfu-util to flash the binary over USB. This may require putting the board into DFU/bootloader mode (shorting a specific pins or using a menu option).
    • ST-Link or programmer: If no bootloader is present, you may need an SWD programmer (ST-Link V2) to write the firmware directly to the MCU.
  4. Validate: After flashing, reboot and verify the firmware version and core functions (display, movement, temperature sensors).
  5. Restore/adjust settings: Custom firmware may start with default steps/mm and thermals; re-enter calibrated values. Run PID autotune for hotend and bed if needed, and set EEPROM save.

Post-installation checks and calibration

  • Thermistor readings: Heat nozzle and bed to typical temperatures and compare to an external thermometer if available. Check for runaway or incorrect values.
  • Motion tests: Home axes, test jogging, and issue small moves to ensure correct direction and distance. If an axis moves the wrong way, reverse the stepper direction in firmware.
  • Endstops and homing: Confirm endstops trigger and homing finishes reliably.
  • PID tuning: If temperatures oscillate, run PID autotune and save settings.
  • First-layer calibration: Re-level the bed or set new Z-offset especially after changing firmware or enabling mesh bed leveling.
  • Print a calibration object: Print a small cube and dimensional calibration test to confirm E-steps, flow, and steps/mm.

Troubleshooting common issues

  • Printer fails to boot after flashing: Reinsert original SD card firmware (if backed up) or use a programmer/DFU to restore factory firmware. Check for incorrect binary or wrong board selection during build.
  • Touchscreen not responding or missing menus: Many custom firmwares lack the OEM touchscreen interface. Using official firmware or a firmware build that retains touchscreen support is necessary for full UI features.
  • Thermistor errors or temperature safety shutdowns: Verify thermistor type in firmware matches installed sensor; incorrect thermistor settings can trigger false errors or dangerous readings.
  • Axis moves too far or too short: Steps/mm are misconfigured. Recalculate and set correct values for X/Y/Z/E and save them to EEPROM.
  • Bootloader missing: Some boards do not have a user-accessible bootloader; flashing may require an ST-Link or soldering headers.

Risks and warranty considerations

  • Voiding warranty: Installing custom firmware can void manufacturer warranties. Check warranty terms before proceeding.
  • Bricking the controller: Incorrect flashing or wrong binary can render the controller unresponsive. Having the original firmware or a recovery procedure reduces risk.
  • Safety hazards: Misconfigured thermal settings risk overheating or thermal runaway. Always verify thermistor types and enable thermal protection in firmware.
  • Loss of OEM features: Official touchscreen menus, proprietary filament profiles, or cloud features may be lost with custom firmware unless specifically supported.

Best practices and recommendations

  • Prefer official firmware for general users who want safety and full OEM features.
  • If installing custom firmware, use community-validated builds for Qidi X-Plus rather than generic configurations.
  • Keep a copy of original firmware and configuration files for rollback.
  • Make incremental changes, validate after each step, and document settings.
  • Use a reliable power source and do not interrupt the flashing process.
  • Join user communities (forums, groups) to find model-specific guidance and tested configuration files for Marlin or other firmwares.

Conclusion Flashing firmware on the Qidi X-Plus can bring important fixes, new features, and support for hardware upgrades, but it also carries risks including warranty loss and potential bricking. For most users, applying official firmware updates via SD card provides a safe, straightforward improvement path. Advanced users can gain significant benefits from custom firmware (such as Marlin) if they carefully match configuration to their board and peripherals and follow tested flashing procedures. Whether performing an official update or installing custom firmware, careful preparation, backing up existing settings, validating post-flash behavior, and following safety precautions will minimize problems and produce better printing results.

Here’s a solid, step-by-step blog post tailored for QIDI X-Plus owners. It focuses on safety, common pitfalls, and the official upgrade path.

Blog Title: QIDI X-Plus Firmware Update: A No-Nonsense Guide (And Why You Should Do It)

Intro: The Love/Hate Relationship with 3D Printer Firmware Let’s be honest—updating firmware on a 3D printer feels a lot like updating your router’s firmware. You know you probably should do it, but the fear of bricking the device usually wins.

The QIDI X-Plus is a workhorse. It’s reliable, enclosed, and handles engineering materials better than most printers in its price range. But that reliability hinges on one thing: keeping its firmware up to date.

Whether you’re chasing a new feature (hello, better ABL probing) or fixing a bug that caused that last catastrophic layer shift, this guide will walk you through the official QIDI X-Plus firmware install process—without the panic.

Before You Touch Anything: Two Critical Warnings

  1. Don’t use the “Wrong” file. The QIDI X-Plus, X-Plus 2, and X-Plus 3 use completely different firmware. Using the wrong one will brick your screen or mainboard. Always double-check your model on the back label.
  2. This is the official path. This guide covers the stock Marlin-based firmware from QIDI. If you’re looking for Klipper or a community build, this isn’t that guide.

What You’ll Need

  • A microSD card (8GB or smaller works best—the X-Plus bootloader is picky).
  • A microSD card reader for your computer.
  • The latest firmware .zip file from the QIDI Tech support page (we’ll link it below).
  • Patience (the printer will beep and flash—don’t panic).

Step 1: Identify Your Exact Current Version On your X-Plus touchscreen:

  • Go to Settings > About Machine.
  • Write down the current firmware version (e.g., V1.0.9 or V2.4.5).
  • Pro tip: If your version is older than 6 months, you’re likely missing thermal runaway protections or improved motion algorithms.

Step 2: Download the Correct Package Navigate to [QIDI’s official download page] (usually qiditech.com/pages/download).

  • Select X-Plus (not Pro, not Max, not 2).
  • Download the “Firmware & UI” bundle. Do not just grab the mainboard file—you need both parts.

Step 3: Prepare the SD Card (The Critical Step)

  1. Format your microSD card to FAT32 (not exFAT or NTFS).
  2. Set the allocation unit size to 4096 bytes.
  3. Extract the .zip file. Inside, you’ll typically see two folders: Mainboard and UI (User Interface).
  4. For the mainboard update: Copy ONLY the QIDI_UPDATE folder (or the .bin file, depending on the version) to the root of the SD card.
  5. For the UI update: You’ll do this separately using the same SD card (or a second one), following the same root-directory rule.

Step 4: Update the Mainboard (The Brain)

  1. Power off the X-Plus completely. Unplug it for 10 seconds.
  2. Insert the SD card (with the mainboard update) into the printer’s internal SD slot (behind the touchscreen door, not the front panel slot).
  3. Power on the printer.
  4. What to expect: The screen will stay blue or show a progress bar. You’ll hear a series of beeps (3-5 beeps is normal). After about 30 seconds, the printer will either reboot or go silent.
  5. Success indicator: The printer boots to the home screen. Power off, remove the SD card, and delete the firmware file from the card (or the printer will reflash it next boot).

Step 5: Update the Touchscreen UI (The Face) This step is where most people get stuck.

  1. Take that same SD card and delete the mainboard files.
  2. Copy the UI folder contents to the SD card root. Look for files named DWIN_SET.
  3. With the printer powered off, insert the SD card into the internal slot again.
  4. Power on.
  5. You’ll see a blue screen with orange text showing file counts (e.g., “Writing 0/128”). Do not touch anything. This takes 2–4 minutes.
  6. When it says “End” or reboots to a calibration screen, power off, remove the SD card, and power back on.

Step 6: Re-Calibrate (Non-negotiable) A new firmware means new default values. You must:

  1. Run Auto-Leveling (from the Tools or Settings menu).
  2. Re-set your Z-offset using a piece of paper.
  3. Run a PID autotune for the hotend and bed (usually hidden in the Settings > Advanced menu).

Troubleshooting: When Things Go Wrong

| Problem | Most Likely Fix | | :--- | :--- | | Screen stays blue after mainboard update | Bad SD card format. Re-format FAT32, 4096 bytes. Use a 4GB or 8GB card. | | UI update hangs at “0/128” | The DWIN_SET folder is corrupted. Re-download the zip and replace the folder. | | Printer boots but touchscreen doesn’t work | You updated the mainboard but not the UI. Go back to Step 5. | | “No printer attached” error | The ribbon cable between screen and mainboard is loose. Happens during vibration. Re-seat it. |

The Verdict: Is It Worth It? Yes—with a caveat. Installing Qidi X-Plus Firmware: A Step-by-Step Guide The

The official QIDI firmware isn’t exciting. It won’t give you a fancy web interface or input shaping (that’s what the X-Plus 3 is for). But it will fix silent bugs: thermal runaway false triggers, SD card read errors, and first-layer inconsistencies.

If your X-Plus is printing perfectly right now? You can skip the update. But if you’ve seen any weird behavior—save this guide for a rainy afternoon.

Final Tip: Join the r/QIDI community on Reddit before updating. Search for your exact firmware version number. Sometimes the community finds bugs before QIDI posts a retraction.
