The T indicates the number of teeth or ridges in the servo spline. You need to match the servo spline to any device splines or they won't mate. :EDIT: Because it's a good link, and because I hate it when links to resources rot, I figured I'd duplicate the information here from the excellent Servo City: Servo Splines Servos have an output shaft that ...

Industrial servos with integrated driver and encoder have a limited power compared to non-integrated counterparts. Other then that, their spec sheet specifies their accuracy and if they are good/acceptable quality they will conform the spec sheet. You can extrapolate the positioning accuracy of your robot, based on your mechanism and the positioning (in)...

This is something I used in a Lego assembly some time back. It's using an FS90 servo which is considerably smaller than the one you list, but You can get the picture. This version of gluing things on, allows some amount of disassembly and reuse. Other glue jobs are not equally as graceful. To get the servo horn screw in, I had to knock off the corners of the ...

grbl has a trapezoidal velocity profile. It has an acceleration limit (so a ramp on the velocity), but does not set a jerk limit. Jerk limiting would be probably an overkill for stepper-motors. However, grbl does use smooth stepping on for the stepper motors, this reduces the stepping frequency induced vibrations. Source: here

If you are not familiar with the unit of measurement: 1 oz-in = 0.00706 Nm if you are not familiar with torque: 1 Nm torque translates to 1N of force at a radial distance from the shaft of the motor of 1 m. As 1N gravitational force corresponds to an approx. 0.1kg weight, 1 Nm torque can lift* 0.1kg weight 1m away from the shaft, or 1 kg weight 0.1m away ...

Measuring motor temperature and either forcing a stop or limiting performance when it gets too hot is common practice. I have always used a simple thermistor. You should make it have intimate contact with the motor's metal either by using thermal paste or epoxy. Sometimes, you can put it in a small hole drilled in the motor mount. The danger with ...
