FSL40 Version 2.0 Linear Guide Rail Slide Ball Screw Motion Table CNC Linear Guide Stage Actuator Motorized Nema 23 Stepper Motor[350mm Stroke Work Size]

Works well with a DM542 driver I had. The sensors seem accurate.

I’m building a 1000mmx1000mmx100mm cnc plasma cutter with these. They work great and if you go to their US website for technical questions they will work with you to buy brackets, drag chains, and anything else you need. I’ve even received drawings from their team. Be patient with them because of the time zone difference but they will work with you for a good solution.

Company made CAD files available to the specific model. Solid product.

I got 4 of the 800mm for the Z axis on my 3D printer and they are amazing! May not be for the average 3D printing hobby person. But for someone who prints for profit, these are great. The consistency, accuracy and durability is top notch. This means less time is spent adjusting the Z axis between prints. i can easily load the same file, print and walk away with confidence. The only reason why i didn't give it a 5 star was because 2 of the ball screw plates were slightly loose. It was a simple fix. loosen the 2 screws, push the bracket and tighten the screws. A loose bracket could reduce accuracy. Thankfully i caught before installing them. Also, i wished they came with 2.8A motors. I swapped out the original 2A motors for 2.8A so i wouldn't sacrifice torque while being inside a heated enclosure. otherwise i would have had to reduce the Amps to keep them under their Max Temp. Overall, im extremely happy with these! I may purchase 3 more to convert the X &Y Axis to a ball screw system.

Poor quality it’s broken even before a single use

Works amazing

We purchased this actuator to automate an inspection system. It was in inventory at Amazon and available for next day delivery. All in all .. we are happy with the service and the device.

The description shows holes through the mounting rails and says "The backplane is provided with fixed mounting holes for secure installation." Well, those holes are just not there. Others have posted pictures, the linear guide is mounted on standard un-modified 8020 rails. Didn't think I was going to need them so I didn't return, but now I realize I need them and will have to drill through myself... Also, the unit is listed as FSL40 but is actually FSK40. The on-page instruction manual is poorly translated. I ended up using the Chinese side with Google lens to translate. Other than that, it's a NEMA-23 and works well.
