General Mach Discussion / DIY stepper-servo
« on: April 28, 2023, 01:53:31 AM »
I've recently seen a new type of stepper driver board that has a solid-state rotary encoder chip fitted. The boards fit on the back of a stepper which has to have a shaft extension, on to which is fitted a small magnet. These encoder chips (from Broadcom for example) can have extraordinary resolution and accuracy at low price. See for example here:

The result is a stepper-servo drive in effect, though you have to do your own "system integration".
Does anyone have experience with these please?
