TMC2209 is a stepper motor driver chip from German firm Trinamic that I suspect folk interested in the insides of 3D printers will be hearing a lot more about in the near future. In many printers, the ...

The Toshiba TC78H670FTG two-phase, bipolar, stepper-motor driver removes the need for any external current-sense resistor by incorporating on-chip current detection. It’s often desirable or even ...

There are a few 32-bit ARM-based 3D printer controller boards out there such as the Smoothieboard, the Azteeg X5 mini, [Traumflug]’s Gen5 electronics, whatever board is in the Monoprice MP Mini Select ...

Alllegro MicroSystems, LLC rolled out a new 40 V motor driver IC capable of driving one stepper motor and one DC motor. The stepper driver outputs are rated up to 1.6 A and the DC driver at 3.2 A.

Medium-sized cnc machines, which I am defining as those using NEMA 23 and 24 motors, need about 5A per stepper, usually mandating separate driver modules alongside a control board. However, 3d printer ...
