The world's first torque-limiting turn knobs for 3D printer timing belts. Engineered to click exactly at the perfect tension. Never under-tighten or over-tighten your X and Y axes again.
Precision components designed for optimal dimensional accuracy.
Internally calibrated to slip exactly at 6 lbs of linear tension. When you hear the click, your belt is perfectly tensioned.
Designed with standard M4 threading to seamlessly replace compatible stock tensioner hardware.
Over-tightened belts can place unnecessary loads on stepper motor bearings. TorqTune provides repeatable belt tension without guesswork.
Select your printer to find the correct TorqTune configuration.
See how precise tension eliminates common print artifacts.
Properly calibrated belt tension yields smooth walls, sharp corners, and precise dimensional accuracy.
Under-tensioned belts can allow positional errors and contribute to layer shifts.
Improper belt tension can contribute to mechanical vibration and visible ringing artifacts.
Install in under 60 seconds.
Unscrew your existing plastic tensioner knob from the X or Y axis.
Screw on the TorqTune knob and begin taking the slack out of the belt.
Turn until the internal clutch clicks and spins freely. You're perfectly tuned.
