TL Smoother Addon Module,3D Printer Step Motor Drivers Controller for Pattern Elimination Motor Clipping Filter (6 Pack)

These will help reduce flyback voltage to your steppers to smooth out spikes which can cause unwanted artifacts. Super easy to hook up. A good, easy upgrade for a 3d printer. Super deal too. These improved the quality of my prints by eliminating salmon-skin.

It does what it says… removes patterns from 3D prints. I installed these on my Ender 3 pro to get rid of the annoying stripe pattern (shown in the first image) I am blown away by what a board with some diodes can do for 3D prints. I didn’t notice much change in stepper noise, though. But I was much more interested in how they affected print quality. One caveat: they are intended to be installed between the main board and the cable, not the cable and the stepper (the connector is different on the stepper end), I plan on building a secondary enclosure to hold the boards behind the main control box on my unit, so they’re not just flapping around.

It's not a huge deal to me, but I figured it might be for someone.. the product photo shows branded chips, and the actual product arrived with generic/no name chips. I don't care, but some people are sensitive to this sort of thing.. also.. on a positive note, another thing that doesn't match the photo is the solder job! The actual product came with nicely soldered joints, and everything is done really nicely, unlike the terrible solder joint shown in the photo. Im happy about this difference.

Put them on my Ender 3 Pro. Easy to attach and have nice jumper cables. Right away I noticed a vibrating noise when I had it go "Home". The motors worked fine however they were moving in a way that cause a vibration. I did 3 prints and it never changed. It's rather annoying since the printer is so quiet with the new MB. I noticed no difference in print quality from without them. I was surprised because you can physically feel the vibration in the chassis. So maybe I did something wrong but it doesn't matter with direction you hook them up. From my point of view it was a waste of time and money. Perhaps you may have different results.

I would definitely recommend this.

I haven't been able to measure any difference in print quality, but I also haven't run very many tests. Easy install, and they seem to work.

I put 4 on my Ender 3. One was for the extruder. The extruder was doing some funny things so took that one off. Did a test print, compared it to a before and noticed a small difference in the print. This was a small print though that really had no issues in the before.

I installed a set of these on my ROBO3D printer and there was a noticeable print quality increase, The biggest change was the how quite the stepper motor noise got. I can't hear them anymore. So I decided to put them on my Maker Select Plus IIIP, The motors are very noisy on this printer, unfortunately it did not help with the noise level on this printer, On a good note I did notice the prints are smoother looking. Still worth the price. I would buy them again.
