The VEHO 800-12 is a very tall Tronxy printer with an 800 x 800 x 1200 mm plate, a 320 °C direct-drive hotend and Marlin firmware. It is for makers who want an extremely large build space and are comfortable with a basic, offline machine.
Manual lists "USB cable (for skilled users)" beside TF card and USB disk; Tronxy Marlin build with a CH340 USB-B port (community notes), like the VEHO 600.
来源
Choose the 800-12 when height and floor area matter more than modern features: it has no Klipper and no Wi-Fi in our facts, so it prints from SD or USB. If you want Klipper and network control, take the VEHO 800 Pro; if you want a closed chamber, the VEHO 800A. SimplyPrint compatibility through OctoPrint is expected for this Marlin printer but has not been confirmed.
优点
800 x 800 x 1200 mm build volume, one of the tallest plates in Tronxy's range (Tronxy).
320 °C direct-drive hotend, a silicone heated bed with tempered glass and insulation, and an optional magnetic PEI sheet (Tronxy).
Linear guide rails on X, Y and Z with a ball lead screw on Z, and TMC2209 quiet drivers (Tronxy).
Expected to work with SimplyPrint through OctoPrint (not yet confirmed).
7-inch screen and eight interface languages (Tronxy).
缺点
Marlin firmware without Klipper, and no confirmed SimplyPrint method yet; OctoPrint is only expected to work.
Files go in by SD card or USB only; no Wi-Fi or Ethernet is listed, so it is not remote-friendly without OctoPrint.
Open frame without a camera on the page, so large long prints are unsupervised.
Sources disagree on hotend temperature: Tronxy's page says 320 °C, our facts say 335 °C. No independent review found.
适合谁
学校不太适合
A very large open machine with a hot nozzle; not a classroom printer.
业余爱好者可用
Cheap way to print very big, but older Marlin firmware and no network connection make it less pleasant than the Klipper models.
企业可用
Fits oversized parts, but it needs supervision and has no independent reliability data.
打印农场不太适合
No Klipper, no network and a size nobody puts in 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.
[8][9][6][7]
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.
[6]
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.
[4][8][10]
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
