Hi
Bought this one off Amazon,
RoboJax MG996R Metal Torque Gear Digital Servo
Issues:
The back side chrome screw heads are bit large, I had to file the DSE hole larger.
The cable connector different type, modified to fit.
Irritating, the brass gear was bit larger, had to heat up the bearing lever to press fit.
So DSE backup at this point (bed level issues, so still not actually printing models yet)
