grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

TRINAMIC Motion Control's new TMC2660 stepper motor driver IC supports motor drive currents up to 4A. The new IC integrates both a pre-driver for real-time calculation of motor coil current values, ...

Packaged in a single multi-chip module, the integrated driver/amplifier achieves the lowest power dissipation currently available for a 4A stepper motor driver.

Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.
