Enhanced 425Oz Stepper Motor Router with Extended Length Review

Bought these for my first CNC build. The engines run great with no problems. I had to connect them. If you're a beginner like me, remember the current rating is 4.2a. A cheap $7 driver won't work. These bad guys need big drivers. When construction was complete and testing began, cheap drivers worked just fine. When trimmed, cheap drivers just couldn't compete with them. Invest in good drivers to take full advantage of these engines.

I was surprised to see such a great stepper for such a low price so I decided to buy one and see how well built it is. Well I've since bought two more and plan to use them in a CNC router/mill. They're pretty well done. I think my only real complaint is that the shaft is a D-shaft and not a spline, but I think it probably won't matter in the end. Can't wait for the car to work. I checked the motor and while I have no way of checking the torque rating, it seems relatively accurate. Considering…

Used to replace the stern drive motor on my 900X600 laser cutter. Connected to the laser cutter, Z-access allows me to change focus as I work. I wanted something big enough and this one manages without missing a step. This engine is pretty big. About 2-2.5 times larger than the X and Y steppers on my cutter. I set up the stepper motor driver with as few microsteps as possible to keep the torque as high as possible. In any case, Z access does not require a large amount of microstepping. Driving…
