TL-Smoother module for 3D printer motor drivers V1.0 A smoother module for stepper driver motor is an add-on module for stepper motors of 3D Printers. It is useful for a softer movement in Delta Style 3D Printer as when using DVR8825 or step and drives and A4988/2 driver unit. TL smoothers are popular little printed circuit boards (PCBs) that are often used in FDM 3D printers to not surprisingly, smooth out the look of prints. In other words, they reduce surface artifacts caused by irregular stepper motor motion, often dubbed “zebra stripes,” “salmon skin,” etc. These smoothers are often sold as 4- and 8-diode variants, with the 8-diode ones (pictured above) offering a stronger smoothing effect. They plug into any 3D printer between the stepper drivers and the stepper motors, working their electrical “magic” without any other setup needed. Their low cost, plug-and-play functionality, and seemingly magical effect have made them quite beloved, albeit slightly controversial. 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. You will get smoother movement. Features: Suitable for all FDM types of 3D printers Lower vibration, lower noise, and smoother result. Smoother movement especially on the delta-style 3Dprinter under DVR8825 stepper drivers and A4988/2 drivers.
