Tighten each screw a little at a time so the wheel is pulled onto the collet evenly. For typical shafts, you will be able to tighten until the collet plate is almost flush with the back of the wheel, and the front of the collet is almost flush with the front of the wheel. If your shaft is a little larger than nominal, the collet might not press as far into the wheel, and if your shaft is a little smaller than nominal, you can insert something like a small washer between the collet plate and the collet to let it push the collet even farther into the wheel (i.e. past flush). Be careful not to over-tighten the screws as this can strip the threading on the collet plate.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eNote that it is possible to assemble the wheels with a little wobble, but if that is a concern in your application, you can adjust how you tighten the three screws to get it as lined up as you like.

Tighten each screw a little at a time so the wheel is pulled onto the collet evenly. For typical shafts, you will be able to tighten until the collet plate is almost flush with the back of the wheel, and the front of the collet is almost flush with the front of the wheel. If your shaft is a little larger than nominal, the collet might not press as far into the wheel, and if your shaft is a little smaller than nominal, you can insert something like a small washer between the collet plate and the collet to let it push the collet even farther into the wheel (i.e. past flush). Be careful not to over-tighten the screws as this can strip the threading on the collet plate.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eNote that it is possible to assemble the wheels with a little wobble, but if that is a concern in your application, you can adjust how you tighten the three screws to get it as lined up as you like.

Under the right conditions, these spikes can exceed the 35 V maximum voltage rating for the A4988 and permanently damage the board, even when the motor supply voltage is as low as 12 V.

A microstepping driver such as the A4988 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. For instance, driving a motor in quarter-step mode will give the 200-step-per-revolution motor 800 microsteps per revolution by using four different current levels.\u003c\/p\u003e\n\u003cp\u003eThe resolution (step size) selector inputs (MS1, MS2, and MS3) enable selection from the five step resolutions according to the table below. MS1 and MS3 have internal 100kΩ pull-down resistors and MS2 has an internal 50kΩ pull-down resistor, so leaving these three microstep selection pins disconnected results in full-step mode. For the microstep modes to function correctly, the current limit must be set low enough (see below) so that current limiting gets engaged.

In such cases, an alternative approach is to initially use longer M3 screws to engage the threads of the machined piece.

When the longer M3 screws cannot be tightened further, you can replace them with the included 14 mm screws and finish the assembly.\u003c\/p\u003e\n\u003ch2\u003eDimensions\u003c\/h2\u003e\n\u003cp\u003eThis adapter is intended to work with motors with 5mm diameter output shafts, and it fits most wheels that are compatible with standard 608 ball bearings.

The extremely precise, high-resolution servo pulses have a jitter of less than 200 ns, making these servo controllers well suited for high-performance applications such as robotics and animatronics. Built-in speed and acceleration control for each channel make it easy to achieve smooth, seamless movements without requiring the control source to constantly compute and stream intermediate position updates to the Mini Maestros.\u003c\/p\u003e\n\u003cp\u003eThe Mini Maestros also feature configurable pulse rates from 1 to 333 Hz and can generate a wide range of pulses, allowing maximum responsiveness and range from modern servos. Units can be daisy-chained with additional Pololu servo and motor controllers on a single serial line.\u003c\/p\u003e\n\u003cp\u003eA free configuration and control program is available for Windows and Linux, making it simple to configure and test the device over USB, create sequences of servo movements for animatronics or walking robots, and write, step through, and run scripts stored in the servo controller. The Mini Maestros’ 8 KB of internal script memory allows storage of up to approximately 3000 servo positions that can be automatically played back without any computer or external microcontroller connected.\u003c\/p\u003e\n\u003cp\u003eBecause the Mini Maestros’ channels can also be used as general-purpose digital outputs and analog or digital inputs, they provide an easy way to read sensors and control peripherals directly from a PC over USB, and these channels can be used with the scripting system to enable the creation of self-contained animatronic displays that respond to external stimuli and trigger additional events beyond just moving servos.\u003c\/p\u003e\n\u003cp\u003eThese fully assembled versions of the Mini Maestro ship with 0.1″ male header pins installed as shown in the product pictures.

Because the tracks are elastic, they will maintain tension even if you do not precisely match this distance.
