FUYU FSL40 Mini Linear Stage Small Slide Guide CNC Screw Lead Motion Table Motorized Nema 23 Stepper Motor[300mm Stroke Work Size]

Amazing value for the money. Be a bit careful, the stepper wiring colours don't agree with the manual, but wow ! the rest of it. REALLY nicely put together, perfect components for our project.

For the price, I would expect something to use a MGN15H or MGN12H linear block. This one uses MGN12C. Too small of a block to handle heavy designs. If the manufacture could add a few dollars to upgrade it to a MGN12H, this is much better. What a disappointment.

These seem like such a well thought out product for the price. But about half of them (I bought five of various sizes) lock up or get very rough somewhere in the travel. The linear slides are decent.. The ball screws are poor at best. They do all have a giant smear of "Hope this fixes the problem" grease somewhere, the bad ones have more. I suspect that the ones that make it to Amazon are the ones that failed quality control in China and can't be sold there, because people would drive them back over and dump them on the manufacturer's door. Keep looking.
