The new I/O module controls stepper motors with Modbus/TCP, Ethernet/IP or PROFINET interface to host PC, PLC or PAC.

The Arduino-based evaluation kit (EVK) is said to supports the evaluation of ROHM Semiconductor’s motor driver devices and enables, facilitates and accelerates customers’ developments. Designed as a ...

Very nice project. As described in the video, for servo motor v dumb stepper, servo motor is more efficient and servo motor won’t miss steps, or at least not without being able to provide a warning.

One of the bigger problems with any CNC machine or 3D printer is the issue of missed steps when moving the toolhead. If a stepper motor misses a step, the entire layer of the print – and ever… ...
