Featured machines

ZeroG Hydra Large-format CoreXY · quality-first · sensor-rich A custom Mercury/Hydra build designed around a large build volume, automated calibration, and repeatable print quality instead of chasing speed alone. Three-point floating bed with automatic tramming Beacon eddy-current probing and accelerometer Filament monitoring, cutter, LEDs, and toolhead display Phaetus Rapido hotend and Clockwork 2 extruder Build story + gallery →   Configuration files →

Delta 3D Printer Closed-loop motion · custom effector · CPAP cooling An experimental high-speed delta built from a TEVO Little Monster frame and developed through three generations of custom effectors. NEMA 17 closed-loop steppers with encoder feedback Remote CPAP blower for lightweight part cooling Direct-drive extrusion and nozzle-mounted probing Pivoting TFT35 interface running KlipperScreen Build story + gallery →   Configuration files →

Voron V0.2990 High-speed V0.2R1 · custom high-flow toolhead · serviceable electronics A serialized Voron V0.2R1 pushed beyond its stock configuration with custom cooling, filtration, monitoring, lighting, and electronics mounts. 225–350 mm/s printing and up to 650 mm/s travel Custom high-flow toolhead and auxiliary cooling Active carbon filtration and chamber monitoring Camera automation, runout sensing, and hinged electronics access Build story + gallery →   Configuration files →

Before using a configuration

Caution

These files were written for specific custom machines. Do not copy a configuration directly to another printer without checking its hardware.

At minimum, verify:

• MCU pin assignments and stepper direction
• Thermistor and temperature-sensor types
• Heater limits, power control, and thermal protection
• Bed dimensions, axis limits, and homing behavior
• Stepper currents, microsteps, rotation distances, and gearing
• Probe offsets, safe Z movement, and emergency shutdown behavior
