The VEHO 3 is a mid-size open-frame Tronxy Klipper printer: 330 x 330 x 400 mm, 320 °C hotend and 600 mm/s listed speed. It is for hobbyists who want an affordable, fast Klipper machine and are happy to tinker.
Ships Klipper with Moonraker: KlipperScreen on the touchscreen, Mainsail in the browser at the printer's IP (manual, resonance-compensation section).
来源
Choose the VEHO 3 for a Klipper printer with a 330 mm plate in PLA, PETG and TPU. It is open frame, with an enclosure only as an option, so ABS and ASA are harder; the VEHO 3A is the enclosed version and the VEHO 4 has a bigger 400 mm plate. If you want something that works with no tuning, a Bambu Lab A1 or P2S has independent reviews behind it, which the VEHO 3 does not.
优点
330 x 330 x 400 mm build volume with a 320 °C hotend (Tronxy).
Klipper firmware at up to 600 mm/s, so it works with SimplyPrint through Klipper.
Four independent Z motors, 36-point auto-levelling, seven linear guides and resonance compensation (Tronxy).
Magnetic removable PEI bed, filament run-out detection and Wi-Fi, Ethernet and USB (Tronxy).
Dual-drive large-gear extruder with a 320 °C hotend (Tronxy).
缺点
Open frame; Tronxy lists a full enclosure only as optional, so ABS and ASA are harder.
No camera in our facts.
No independent hands-on review found; only Tronxy's own claims.
Express and air shipments are priced without import duties and taxes, which the buyer pays at customs; Tronxy lists sea shipments as tax-free, door to door.
适合谁
学校可用
Easy to start Klipper printing on, but the open frame leaves hot parts in reach; the enclosed VEHO 3A suits a classroom better.
业余爱好者适合
A big plate and Klipper, if you accept tinkering and no independent review.
企业可用
Fine for PLA and PETG prototypes, but open frame, no camera and no track record.
打印农场不太适合
No camera, no plate-swap kit in our facts and no reliability record for a fleet.
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.
[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.
