4-Pack TL-Smoother PLUS Module for 3D Printer Motor Drivers
4-Pack TL-Smoother PLUS Module for 3D Printer Motor Drivers
4-Pack TL-Smoother PLUS Addon Module for 3D Printer Stepper Motor Drivers
Upgrade your 3D printer's performance with the Mellow TL-Smoother PLUS addon module — a plug-in board designed to deliver smoother stepper motor movement, reduced vibration, and quieter operation. Compatible with a wide range of popular 3D printers including Delta Kossel, MakerBot, Reprap MK8 i3, and Ultimaker 2.
What Is the TL-Smoother PLUS?
The TL-Smoother PLUS is an addon circuit board that installs between your 3D printer's stepper motor driver and the motor itself. It provides flyback diodes (freewheeling diodes) on all motor outputs, protecting motors against induction voltage spikes even when the driver is in an unpowered state. The result is noticeably smoother motion, especially on delta-style 3D printers running DRV8825, A4988, or A4988/2 stepper drivers.
Key Features
- Smoother Movement: Significantly reduces stepping artifacts and improves print quality on delta and Cartesian printers alike.
- Lower Vibration & Quieter Operation: Dampens motor vibration for a quieter printing experience.
- 8 Large SMC Package Diodes: Big SMC diodes offer superior heat dissipation and can handle larger motors compared to small surface-mount diodes.
- No Assembly Required: Ready to install right out of the box — just plug in and start printing.
- Broad Compatibility: Works with DRV8825, A4988, and similar drivers used in Delta Kossel, MakerBot, Reprap MK8 i3, Ultimaker 2, and more.
- Protection for Motor Outputs: Flyback diodes protect stepper motor windings from voltage spikes during operation and at rest.
- Pack of 4: Includes four TL-Smoother PLUS modules — enough to cover all axes on most 3D printer configurations.

Who Is This For?
Whether you're a hobbyist fine-tuning your delta printer or a maker looking to eliminate unwanted noise and stepping artifacts from your Reprap build, the TL-Smoother PLUS is an affordable, effective upgrade. It's especially recommended for machines that exhibit surface ribbing, ringing, or inconsistent motion — the larger SMC diodes make it even more effective on higher-current motors.

Frequently Asked Questions
Q: What 3D printers are compatible with the TL-Smoother PLUS addon module?
A: The TL-Smoother PLUS is compatible with most 3D printers that use DRV8825, A4988, or A4988/2 stepper motor drivers. This includes popular models such as Delta Kossel, MakerBot, Reprap MK8 i3, and Ultimaker 2. If your printer uses one of these common stepper drivers, the TL-Smoother PLUS should be a direct-fit upgrade.
Q: How many TL-Smoother PLUS modules come in the pack, and do I need one per axis?
A: This listing includes 4 TL-Smoother PLUS modules per pack. Most 3D printers use 3–5 stepper motors (X, Y, Z, and one or two extruders), so a 4-pack is typically enough to cover the primary motion axes. You install one module per stepper motor driver output for best results.
Q: Do I need to solder or assemble anything to install the TL-Smoother PLUS?
A: No assembly is required. The TL-Smoother PLUS comes fully assembled and ready to install. Simply plug the module between your stepper motor driver board and the motor connector on your printer's mainboard and you're good to go.
Q: Why are the SMC package diodes better than smaller diodes on other smoother modules?
A: The 8 large SMC package diodes used on the TL-Smoother PLUS offer significantly better heat dissipation than smaller surface-mount diodes. This means they can handle higher motor currents without overheating, making the PLUS version more suitable for larger or more demanding 3D printer setups.
