STōN-WoLF
High-speed. Built in Prague. Open source.
Cartesian flying-gantry 3D printer kit with 48V motion, CNC aluminum frame, and Klipper + Mainsail pre-installed.
Built and assembled one at a time. Every unit has a build number and is serviceable by the person who built it.
QUICK OVERVIEW
Build volume: 300 x 300 x 285 mm
Optional Z600: 300 x 300 x 600 mm (made to order, 4–6 weeks)
Travel speed: up to 1500 mm/s
Print speed: 300–600 mm/s
Acceleration: up to 50,000 mm/s² (hardware-limited)
48V motion system
Raspberry Pi CM5 with Klipper + Mainsail pre-installed
WHAT THIS MACHINE IS
The STōN-WoLF removes the usual tradeoff between ease of use and performance.
It ships ready to print from your phone or local browser. No SSH, no internet, no cloud, no terminal, no Linux setup required.
Nothing is locked down. Advanced features can be enabled or disabled at any time.
PERFORMANCE
Travel speed: up to 1500 mm/s
Print speed: 300–600 mm/s depending on material
Acceleration: up to 50,000 mm/s²
Built-in motion safety automatically limits acceleration at high speeds:
Above 1000 mm/s → capped at 25,000 mm/s²
Below 1000 mm/s → full performance allowed
This is enforced at firmware level (motion planner), not slicer or macros.
