Qidi Xplus Firmware Install //free\\ May 2026

Here’s a step-by-step guide for installing firmware on a QIDI X-Plus (assuming you meant X-Plus, as “X-Plus” is the correct model; “Xplus” is a common shorthand).

Troubleshooting Common Issues

The printer ignores the update (Original X-Plus):
- Try a different SD card. Some cards are not readable by the bootloader.
- Rename the .bin file to a shorter name (e.g., update.bin).
Screen freezes during update:
- Wait at least 10 minutes. If it remains frozen, power cycle the printer. If the screen lights up but the printer won't move, the mainboard firmware may need to be re-flashed.
OTA fails (X-Plus 3):
- Check your Wi-Fi connection strength. Use the manual USB method described in Part 1 if the connection is unstable.

Troubleshooting Common Installation Failures

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

Error 2: Printer Freezes on Boot (Blue Screen)

Solution: You have a corrupt flash or mismatched hardware version. You need to perform the "Emergency Recovery":
1. Create a text file on the SD card named reset.txt.
2. Insert the card and reboot. This forces the bootloader to skip the corrupt sector.
3. Re-download the firmware and try again.

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 2: Downloading the Correct Package

Navigate to the official QIDI Tech support page (www.qiditech.com/Support).

Select "X-Plus" from the dropdown.
Look for "Firmware & Software."
Download the .zip file. Do not rename the file. Inside, you will typically find two files:
- QIDI_Update_screen.bin (For the touch screen)
- QIDI_Update_MKS.bin (For the mainboard)

Step 4: Verify and Reset

It is good practice to "Reset to Factory Settings" after a firmware update to ensure old settings do not conflict with new code.

Go to Settings > Restore Factory Settings.
Re-level your bed and check your Z-offset.

Prepare

Download the correct firmware for Qidi X-Plus (match model and version).
Tools: USB flash drive (FAT32), microSD if required, USB cable, PC.
Backup: save current settings and any custom profiles.

Choose flashing method

SD/USB boot: many Qidi printers accept firmware via SD/USB.
USB to serial (advanced): for direct flashing with bootloader tools (requires opening printer).

Flash via SD/USB (typical)

Format USB/SD as FAT32.
Copy the firmware file (usually .bin or .hex) to the root of the drive. Rename if the vendor specifies (e.g., firmware.bin).
Power off the printer. Insert drive.
Power on the printer and watch the display/LEDs — firmware update should start automatically. Wait until complete (do NOT power off).
After success, remove drive and reboot.

Flash via USB (if supported)

Install drivers (VCP/CH340/STM) on PC.
Use vendor-recommended flasher (e.g., Qidi updater or STM32CubeProgrammer/avrdude depending on board).
Connect printer via USB, select correct port, load firmware, and flash. Follow tool prompts.

After flashing

Restore settings/profiles.
Run level/bed auto-home and PID/autotune if needed.
Print a test object.

Troubleshooting

If update fails, try reformatting drive, different USB, or re-download firmware.
If printer won’t boot, try re-flashing original firmware or using USB-to-serial recovery.
If unsure, contact Qidi support or community forums.

If you want, I can:

Provide direct links to official firmware and tools (I can search for latest files).
Walk through the exact steps for either SD/USB method or USB-to-serial for your printer's board.

(Note: you didn't specify whether you want the official or aftermarket firmware; I assumed official. If you want Marlin or custom builds, say so.)

Installing firmware on a QIDI X-Plus varies slightly depending on whether you have the original X-Plus, the X-Plus 3, or the newer X-Plus 4. Most updates are performed offline using a USB drive formatted to FAT32. Preparation: Hardware & Files

USB Drive: Use a drive smaller than 16GB (ideally 8GB or less). Ensure it is formatted to FAT32.

Download: Get the correct firmware package from the QIDI Tech Firmware Download page or the official QIDI Wiki.

Extraction: If the download is a .zip or .rar file, extract it on your computer first. Installation Process by Model QIDI X-Plus 3 & X-Plus 4 The modern X-series utilizes a QD_Update folder structure. Here’s a step-by-step guide for installing firmware on

Transfer Files: Copy the entire QD_Update folder to the root directory of your USB drive. Insert & Update: Plug the USB drive into the printer while it is off. Turn the printer on. Navigate to the Settings (suitcase icon) > About.

An "Offline Update" or "Update" prompt should appear in the lower-left corner. Click it to begin.

Completion: The process can take 20–30 minutes. Do not power off the printer until it restarts automatically. Original QIDI X-Plus

Older models often require "printing" the firmware files like G-code.

Transfer Files: Save the three extracted files (typically update.qd, a .bin UI file, and a .gcode parameter file) to the root of the USB drive. Execute in Order: Insert the USB and go to the Print menu.

"Print" update.qd first. The printer will beep and restart the screen. "Print" the .bin UI file. "Print" the .gcode parameter file to finalize settings. Critical Post-Update Steps Troubleshooting Common Issues

Firmware updates often reset calibration values. Once the update is finished, you must perform the following to avoid print failures: Auto Bed Leveling: Recalibrate the mesh.

Z-Offset Calibration: Ensure the nozzle height is correctly set.

Input Shaping: Run the resonance compensation test if supported by your model. Troubleshooting

Update Not Detected: Ensure the QD_Update folder is the only item on the drive. Some users find unplugging the power cord for 30 seconds before booting with the USB inserted helps.

White Screen/UI Error: If the UI fails to load, you may need a recovery file (like mksclient.recovery or mksscreen.recovery) placed on the USB root to force an automatic reset. To help you find the exact files you need:

Which specific version of the X-Plus do you have (e.g., original, 3, or 4)?
