Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

most simple way to fix stepper motor jitter!
Steppers need acceleration if you want 'em to go fast

Controlling a stepper motor with integrated encoder using C++ on Windows
Something like the Tic T825 you looked at might be fine. An Arudino-compatible microcontroller with the AccelStepper library would be similar but give you more flexibility in choosing any driver that takes step/direction signals.

Looking For Help Adapting a Library to SAMD21 - "iAccelstepper"
I am working on a project that uses an adafruit metro m0 express development board (using the ATSAMD21G18 ARM Cortex M0 processor) to drive a stepper motor. I have elected to use the Accelstepper library as it is well documented and makes controlling the stepper simple. The project also is driving a touchscreen display with the GUIslice library. Now - the Accelstepper library uses the main polling loop() function to repeatedly call the .run() method from the library to produce pulses to the stepper driver and move the motor. I have noted that when having the GUIslice function for polling the display in the same loop() function, it can hang the stepper motion for a split second as the processor is taking time to perform those functions (rightfully so).

How would one run two motors simultaneously at different speeds?
For stepper motors instead that is equally possible by just calling setSpeed(speed) with a different speed value on each motor (assuming the use of the AccelStepper library).

I have some a4988 stepper driver and esp 32 but no driver .How can i code for a diy cnc with these? What will be the instructions?
Hi there. Not sure of what your goal is. I assume you have basic knowledge of electronics. The first step is learning how to step a motor. The https://github.com/waspinator/AccelStepper library can help.

Simultaneously running stepper motors
Others have mentioned the AccelStepper library and I wanted to second this and also give you some example code you can get started with. The following Arduino sketch will spin 2 steppers motors simultaneousy and will hopefully get you started towards what you want to make!

Task Scheduler?
I'm making a Rube Goldberg machine assisted by an Arduino. There's lots of different motors and timed events, so I want to streamline things using a library like . Thing is, I have processes that have to run the whole time, like a rotary encoder reader ( library used), a PID controller ( library used), and a stepper motor ( library used).

Help. Stepper Motor not spinning when I increase the speed
AccelStepper may interest you, and I think Teacup can go even faster.

TMC2209 stepper motor driver: Any functional Arduino Uno example ino (and pinout) for sensorless homing (using stallguard)? Figuring out the appropriate pinout for Arduino Uno when using TMCStepper and TMC2209 libraries has been a little challenging. Thanks in advance for answering soon!
Now take a look at the header file of the library TMCStepper you want to use, https://github.com/teemuatlut/TMCStepper/blob/master/src/TMCStepper.h

Run stepper motor silently over Wi-Fi
My problem is that the library I'm using for the TMC2208 is made for the AVR architecture which means the ESP8266 seems to be incompatible with the code. I belive I have a few options.

(Sound). What caused this? Fully updated board and screen. SKR Pro v1.2, TMC2208, TFT35E3 V3. Only during Touch mode bed calibration (Point1-5)

ESP8266 and stepper driver : serial line interferences
The library is called TMCStepper, and this issue suggests softwareserial cannot be used. I have tested it myself and can confirm this. Solution would be to get an ESP32 that has multiple hardware serial connections.

This is my take on a smart curtain opener that easily retrofits onto any existing curtain rod
I looked into the code and it turns out that TMCstepper makes use of basically 2 functions to write to the register (here lines 187 and 281), so should the example given above not work you have a second option !
