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.

What slicer to use for the Tronxy VEHO 800 Pro
None of the slicers in SimplyPrint's cloud has a ready-made profile for the Tronxy VEHO 800 Pro, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Tronxy VEHO 800 Pro.
Cloud-Based Slicer for Tronxy VEHO 800 Pro
All supported slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your Tronxy VEHO 800 Pro models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Tronxy VEHO 800 Pro: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the Tronxy VEHO 800 Pro
Tronxy doesn't make an app for the Tronxy VEHO 800 Pro. SimplyPrint works as its app: on your phone and in any browser, with a slicer in the cloud.
There's no plate swapper or auto-ejection kit for the Tronxy VEHO 800 Pro in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
Ways to automate it
Your own ejection G-codeWrite the routine that clears your plate, and AutoPrint runs it after every print.

What filament can the Tronxy VEHO 800 Pro print?
Filament compatibility for the Tronxy VEHO 800 Pro: the materials Tronxy lists for it.
Filament
Suitability
Notes
PLA
Great
On the maker's list of materials for this printer.
PETG
Great
On the maker's list of materials for this printer.
TPU & flexibles
Great
On the maker's list of materials for this printer.
ABS & ASA
Great
On the maker's list of materials for this printer.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
With care
On the edge - PC really wants an enclosed, hot chamber to avoid warping.
Carbon-fiber & glass-filled
With care
Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
Best filament for the Tronxy VEHO 800 Pro
Filaments the Tronxy VEHO 800 Pro prints well, Tronxy's own first, then the best known.
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.
Pros
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).
Cons
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.
Who it suits
SchoolsNot a good fit
An open 800 mm machine with a 320 °C hotend is not something to leave students alone with.
HobbyistsGood fit
Enormous plate with Klipper for makers who want to print big costumes, props or furniture parts.
BusinessesCan work
Good for oversized PLA or PETG parts; no chamber and no independent reliability data.
Print farmsNot a good fit
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.
Firmware and custom firmware ●●●●●
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]
Local control and integrations ●●●●●
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]
Third-party filament, slicers and parts ●●●●●
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]
Repairs and spare parts ●●●●●
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]
Community and documentation ●●●●●
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]
Pros
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.
Cons
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.
Track record
October 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.
[8][9]
December 2020: Tronxy launched the XY-3 SE on Kickstarter; the company says shipping finished in April 2021.
