The TL-Smoother is an addon 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 un powered state of the driver.You will experience smoother motor operation especially on the delta-style 3Dprinter under DVR8825 stepper drivers or A4988/A4982 drivers.
8 big Package(SMC)diodes provides better heat dissipation performance that can handle bigger motor than small diodes.
Lower vbration lower noise smoother result！
Note: DO NOT use smoothers with the TMC line of chips (2208, 2130, 2209, 2100)
It worked perfectly, removing vertical resonance lines in my prints.
The name says it all: it's a smoother. I had some "vibration"on axis X and Y. I installed these soomthers on X, Y and the extruder (Hemera on a Geetech I3 Pro B). The enhancement is visible. See attached photo.
Installed them on my Ender3 not that big a difference in sound.
Should have gone with the silent board.
