BIQU TL-Smoother Board V1.0 (Pack of 4)

The BIQU TL-Smoother Board is an add-on module for 3D printer stepper motor drivers.

The board provides flyback diodes (freewheeling diodes) for the motor outputs so that they are also protected against induction voltages in the unpowered state of the driver.

They fit between the stepper drivers and the stepper motors, where they help reduce feedback and inductive charges with flyback diodes. This can make a big difference in the quality of prints produced, as it ensures the stepper drivers and motors always deliver the exact electrical signals and mechanical movements that you’re expecting, resulting in prints that look and feel great without any signs of motor jerking or the common “Salmon Skin” problem.
