Mellow TL-Smoother PLUS — 4-Pack Addon Module for 3D Printer Stepper Motor Drivers
Upgrade your 3D printer's motion quality with the Mellow TL-Smoother PLUS — a plug-in addon module designed to deliver smoother, quieter, and more consistent stepper motor movement. Whether you're running a Delta Kossel, MakerBot, RepRap MK8 i3, or Ultimaker 2, this module is a straightforward hardware upgrade that makes a noticeable difference in print quality and machine operation.
How It Works
The TL-Smoother PLUS provides flyback (freewheeling) diodes across each motor output, protecting your stepper motor drivers against induction voltage spikes — even when the driver is unpowered. This results in cleaner electrical signals, smoother axis movement, and reduced mechanical noise during printing. It is especially effective when paired with DRV8825 or A4988/A4988-2 stepper motor drivers commonly found on delta-style 3D printers.
Key Features
- ✅ 8 Large SMC Package Diodes — Superior heat dissipation compared to small diodes, capable of handling higher motor currents
- ✅ Smoother Motion — Reduces micro-stepping irregularities for cleaner, more accurate prints
- ✅ Lower Vibration & Reduced Noise — Noticeably quieter printer operation
- ✅ Ready to Install — No assembly required; plug directly into your existing motor driver setup
- ✅ Wide Compatibility — Works with Delta Kossel, MakerBot, RepRap MK8 i3, Ultimaker 2, and more
- ✅ Pack of 4 — Enough to upgrade all axes on most 3D printer configurations

Frequently Asked Questions
Q: What does the TL-Smoother PLUS addon module do for my 3D printer?
A: The TL-Smoother PLUS adds flyback diodes to your stepper motor driver outputs. This smooths out the electrical signal delivered to each motor, resulting in more consistent and fluid axis movement, reduced vibration, and quieter overall printer operation — all of which can contribute to improved print surface quality.
Q: Which 3D printers and stepper drivers are compatible with this TL-Smoother PLUS module?
A: This module is compatible with most popular 3D printers including Delta Kossel, MakerBot, RepRap MK8 i3, and Ultimaker 2. It works best with DRV8825 and A4988/A4988-2 stepper motor drivers. If your printer uses one of these driver types, the TL-Smoother PLUS is a straightforward drop-in upgrade.
Q: How many modules are included, and is any assembly required?
A: Each pack includes 4 TL-Smoother PLUS modules — enough to cover all axes on most standard 3D printer configurations. No assembly is required; simply plug each module in between your stepper driver and motor connector following standard TL-Smoother wiring instructions.
Q: Why does the PLUS version use large SMC package diodes?
A: The 8 large SMC package diodes used in the PLUS version offer significantly better heat dissipation than smaller diode packages. This means the module can handle higher motor currents and is more suitable for printers with more demanding or less stable motion systems, providing greater reliability and longevity.
