Weedo X40 3D printer

The Nanjing WEEDO 3D Technology Corporation is a small Chinese FDM printer manufacturer, based in Nanjing approx. 300 km from Shanghai. Weedo mainly produces printers for the consumer sector. Weedo develops the printers in their own development center and also holds over 40 patents. 

The Weedo X40 Idex FDM printer was also developed by Weedo.

Idex means Independent Dual Extruder. The Weedo X40 was therefore equipped with two print heads. The IDEX printheads allow printing with two colors and / or different materials. For example, you can use PVA as a support material, which can be completely dissolved in water after printing. So-called 2K printing (two components) is also possible. So you can print a hard and a soft plastic if the materials are compatible with each other. Enabling, for example, the printing of a box with a printed seal. 

The printer equipment also includes an automatic bed leveling and a filament run out sensor for each extruder. With the Weedo Wiibulid software, two small print objects can be printed at the same time using the two print heads. After printing, the printer is automatically switched off.


 Descripton  Specifification
 Hardware versions  There are two versions of the printer:
  • X40 V1: The first mass production version (Kickstarter Version). The production time is from November 2020 to June 2021.
  • X40 V2: The second production version. The production batch start from July 2021. The length in the Y-axis direction has been shortened. The Y-axis coordinate has been changed from (-2,310) to (-11,303).

 In the case of a firmware update, the appropriate firmware must be installed for the hardware.

Touch screen
  • Size: 4,3" (95mm x 53.9mm)
  • Resolution: 480 x 272 pixel
  • Color: 65K (65536) colors
  • Modell Nr. : DMT48270C043_06WT Interface : FCC 10Pin _ 1,0mm

 2 million-pixel camera that provides VGA video streams based on MJPG encoding.
 The camera resolution:

  • Video streaming 640*480 pixel
  • Still picture 1024*768 pixel

The camera can only be used by one device at a time and the streaming and snapshot functions cannot be used at the same time. For example, you cannot record a time-lapse with Octoprint and at the same time watch the video stream on your smartphone!

 Wifi WIFICAM uses a high-performance dual-core processor, runs at the main frequency of up to 600DMIPS, and integrates 4GB Flash, 802.11b/g/n wireless network module. Only the 2.4GHz frequency band is supported.

A MicroSD card reader is installed on the mainboard. The firmware supports the file systems FAT, FAT32 and VFAT.

FAT32 and VFAT:

  • Long filenames
  • max. 4GiB file size
  • max. 2TiB flash memory
  • Default by MicroSD Cards up to 32GB

The exFAT file system used with larger MicroSD cards (microSDXC-Standard) is not supported. You then need to format the flash memory to FAT32 with VFAT.

 Mainboard / Controller

R73 is the 7th generation 3D printer controller developed by WEEDO3D. It uses a 32bit large capacity mcu, stm32F103vet6, with 512k flash and 64k ram. R73 has 4 endstops, 2 runout sensors, 1 proximity switch, 3 thermistor inputs, and 6 stepper motors, 2 nozzle heating, 1 heated bed, 5 fan output. And support DGUS touch screen, WIFICAM and power management module. Due to the integrated interface, the R73 port is very simple and clear.
