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.

Anyone work making software for CNC machines ?
there is a free projecton github: GRBL.
- Using PySerial how do you wait for confirmation?
-
Programming tutorials?
Did you mean this - https://github.com/grbl/grbl
-
I want some opinions and advices on a personal/educational project (zig on stm32 ,a simple grbl)
You could see if translate-c can handle the grbl source. https://github.com/grbl/grbl

Got a box of parts and can't identify this board.
It's a GRBL board for a small 3-axis CNC machine. GRBL firmware uses gcode just like 3D printers, but CNC gcode has some commands that 3D printers don't, and vice versa, and CNC gcode is modal (remembers certain operations and settings) in ways that printer software such as Marlin/klipper/RRF isn't.

GRBL Error 33 from Arduino Sender, but not from UGS
It's raised in a few places at https://github.com/grbl/grbl/blob/master/grbl/gcode.c

Motors moving inconsistently
GRBL: https://github.com/grbl/grbl (not sure what category this falls under)
- Can I make a quick homing function that only hits the limit switch once?

Digraphs and Trigraphs
Ooh another fun one you may be interested in is how I wrote Teacup's config handling - the user has to provide a config.h with various macros defining their machine setup, and then multiple separate parts of the codebase redefine those macros and re-include the file to build various structures and constants at compile-time

Advice to an engineering student
Since then I've made lots of things like audio amplifiers and effects, motor controllers, 3d printer controllers and firmware (and subsequently smoothieboard), muscle stimulators, bluetooth LED strip controllers, etc

How is max step rate calculated for stepper motor libraries
Teacup can go pretty fast too, I think I've seen it clocked at 48k @ 20MHz although that may have been across 4 motors at once.

Arduino UNO ADC using Embedded C
See here and here for an example from my ESC project, or this example from Teacup

best Microcontroller for fast stepper motors?
https://www.airspayce.com/mikem/arduino/AccelStepper/classAccelStepper.html says "The fastest motor speed that can be reliably supported is about 4000 steps per second at a clock frequency of 16 MHz on Arduino" which is pretty poor - teacup can hit something like 10× that when controlling 4 steppers, and also comes with a non-blocking state machine based gcode parser ;)
-
15 steppers on a Mega?
Teacup had decent performance last time I checked, but it's more a complete firmware project rather than a library.
-
Total beginner, want to control two NEMA 17 stepper motors via mathematical function.
That's hard enough just with linear acceleration let alone complex functions - might be worth converting it to line segments host-side and just streaming basic gcode to a 3D printer firmware over the serial port.
-
Driving a stepper motor faster using AccelStepper
Last time I checked, Teacup can do something like 40kHz on an atmega - might be worth having a play with that?
-
Help. Stepper Motor not spinning when I increase the speed
AccelStepper may interest you, and I think Teacup can go even faster.
-
Just updated to the latest firmware, Can I change acceleration/jerk/etc on the fly now? Middle of a print?
The latest what? Teacup? Marlin? Aprinter? Repetier? GRBL? Something else?
What are some alternatives?
grbl-1-1h-servo - This is a special version of grbl 1.1h version with servo support.
AccelStepper - Fork of AccelStepper
uCNC - µCNC - Universal CNC firmware for microcontrollers
Marlin - Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
Smoothieware - Modular, opensource, high performance G-code interpreter and CNC controller written in Object-Oriented C++
MKS-SERVO42C - MKS SERVO42C, an upgraded version of MKS SERVO42B, built-in Field-Oriented control algorithm, position/speed/ torque closed-loop, 4 Half bridge driver with 8 MOSFET, it makes the motor quieter, lower vibration and Lower calorific.
aprinter - 3D printer firmware written in C++
