The above video demos showing the effects of mitigating motor/rail movement induced vibration has been extended to an effective magnification of 800X!

The Raspberry Pi based multi-axis Stack and Stitch Controllers have also been expanded and custom Printed Circuit Boards designed and fabricated (a few are still available for select DIYers). These include those listed, and in addition high current, voltage and speed stepper motor controllers have been developed for expanding Focus Stacking and Stack and Strict efforts. All these controllers are designed to allow multiple parameter optimization for various motors/rails and setups, even including the development of a Hall Effect Sensor PCB for viewing the Sine and Cosine motor currents for improved motor/rail performance. These systems include programmable camera and strobe optical isolated trigger outputs.
The Trinamic 5130 based controller (used with Pololu Tic-500 in some 3 axis systems) has been extensively tested and evaluated with many flavors of motors & rails, WeMacro, Stackshot, MJKZZ, THK KR15 with NEMA 11, THK KR20 with NEMA 17, HIWIN KK50 with NEMA 17 for example. Other systems are in evaluation and all are working well.
