The VEHO 800 Pro is an open-frame Klipper printer with an 800 x 800 x 800 mm plate and a 320 °C direct-drive extruder. It is for workshops that print very large parts in PLA, PETG or TPU.
Choose the 800 Pro when you need a build volume of 800 mm and Klipper's flexibility and can accept no enclosure. For a closed chamber take the VEHO 800A, and for two-colour prints the 800 Pro 2E. If 800 mm is more than you need, the 500 Pro or 600 Pro V3 cost less and take less space.
优点
800 x 800 x 800 mm build volume with a 320 °C ceramic-heated direct-drive extruder (Tronxy).
Klipper with 36-point auto-leveling, four independent Z motors and seven linear guides (Tronxy).
Filament runout detection that pauses the print and lets it resume (Tronxy).
Works with SimplyPrint through Klipper, with Wi-Fi and Ethernet to connect it.
Large gear dual-drive extruder and a silicone heated bed that heats fast (Tronxy).
缺点
Open frame, and our facts list only PLA, ABS/ASA, PETG and TPU; large ABS parts need an enclosure you add yourself.
The maker's page lists no built-in camera. Add a camera for remote watching.
No independent hands-on review found, so the claims here are Tronxy's own.
适合谁
学校不太适合
An open 800 mm machine with a 320 °C hotend is not something to leave students alone with.
业余爱好者适合
Enormous plate with Klipper for makers who want to print big costumes, props or furniture parts.
企业可用
Good for oversized PLA or PETG parts; no chamber and no independent reliability data.
打印农场不太适合
Very large, open and camera-less; it is not a good unit to multiply across a farm.
Tronxy (Shenzhen Tronxy Technology Co., Ltd) is a Shenzhen 3D printer maker whose founder built the company's first printer in 2013. It sells low- and mid-priced FDM printers, from the X5SA and XY-3 series up to the very large VEHO line (1,000 mm and more), plus Moore clay printers, through its own store, Amazon, eBay, AliExpress, Alibaba and dealers. Buyers are hobbyists, schools and small businesses that want a large build volume for little money.
Mostly open: Marlin source on GitHub, Klipper on the newer large printers, open filament and no cloud. Documentation is thin, and firmware downloads go through an email request.
固件和自定义固件 ●●●●●
Tronxy publishes Marlin source for its STM32/GD32 boards on GitHub (tronxy3d) under GPL-3.0, covering nearly 30 X5SA, XY, D01 and VEHO 500-800 variants, last updated February 2024. Its newer VEHO PRO and A series ship with Klipper, and it sells a Klipper upgrade kit for the X5SA.

本地控制与集成 ●●●●●
We found no Tronxy cloud service or account. The Klipper VEHO PRO prints from a USB flash drive or over a USB data cable, Wi-Fi or Ethernet, all on your own premises, and Tronxy publishes the Marlin source for its X5SA and XY printers, which host software such as OctoPrint drives over USB.
[7][9][11]
第三方耗材、切片软件和零件 ●●●●●
Open filament (1.75 mm, with 2.85 mm print heads for the VEHO) and standard G-code, which any slicer produces. VEHO hotends and print heads such as the Ext06 are Tronxy's own parts.
[6][7]
维修和备件 ●●●●●
Tronxy's store sells model-specific mainboards, hotends, nozzles and extruder kits for current and older lines (X5SA, XY, VEHO), including Klipper-version parts.

社区和文档 ●●●●●
Firmware source and build steps are on GitHub, and upstream Klipper ships configs for eight Tronxy models. Tronxy's own download page asks owners to email for the right firmware instead of offering it directly.

优点
Very large build volumes for the price, up to 1,000 mm and more in the VEHO line.
Marlin source is public on GitHub, and the newer VEHO models run open-source Klipper.
No cloud or account: print over USB, memory card, Wi-Fi or Ethernet.
Spare mainboards, hotends and nozzles sold for current and older models.
缺点
Firmware on Tronxy's website is by email request rather than a direct download.
Dozens of models and variants with similar names (the published firmware alone covers nearly 30), so check carefully which firmware and parts fit.
VEHO hotends and print heads are Tronxy-specific parts.
实绩
十月 2022: Tronxy began publishing Marlin source for its STM32F446/GD32-based boards on GitHub (tronxy3d) under GPL-3.0; it updated it until February 2024.
