Qidi Xplus Firmware Install Site

If you need custom features (e.g., BLTouch, linear advance):

Use PlatformIO in VS Code to compile to firmware.bin.

Install via SD card as in Method 1.

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

Preparations and required materials

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:

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:

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

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.

Flashing method:

Validate: After flashing, reboot and verify the firmware version and core functions (display, movement, temperature sensors).

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.

Risks and warranty considerations

Best practices and recommendations

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.

This guide outlines the standard process for installing or updating the firmware on your QIDI X-Plus (specifically focusing on the X-Plus 3 and modern X-series models) using a USB flash drive. Pre-Installation Checklist

Check Current Version: On the printer touchscreen, tap the Suitcase icon (Settings) > About to see your current version.

Format USB Drive: Use a FAT32-formatted USB drive for the best compatibility.

Backup Settings: If you have custom printer.cfg modifications in Fluidd, back them up before proceeding. Installation Steps If you need custom features (e

This is the core of the qidi xplus firmware install process. This updates the brain of the printer.

Even with a perfect guide, things can go wrong. Here is how to fix the most common qidi xplus firmware install errors.

Before diving into the installation, let’s discuss the "why." The QIDI X-Plus runs on a modified Marlin firmware. Updates usually address three critical areas:

A word of caution: Do not update just for the sake of it. If your X-Plus is printing perfectly, read the changelog first. Only proceed if the update fixes a specific issue you are encountering.

Turn on your QIDI X-Plus. Navigate to the Tool screen (usually the gear icon) > About Machine. Here you will see your current version (e.g., V1.2.3). Write this down. If you are already on V2.1.2, you likely do not need an update. Use PlatformIO in VS Code to compile to firmware

⚠️ Do not rename the .bin files.
