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.

Servo Motor SG-90 keeps overheating when using the pen to go up or down
P.S. This is the link for the GRBL library: https://github.com/robottini/grbl-servo

Stepper motors turn for a bit then vibrate. What’s wrong?
I have no experience in code. I just uploaded this to the arduino. Is there any program that can move my steppers and servos properly?
I’ve tried switching the wires but that didn’t help. I’m supplying the shield with 14V and 2A. The vref of the drivers is 0.48A. I’ve uploaded grbl on the arduino. this one

H-bot pen plotter imprecise
The other thing to consider is the $12 config in GRBL itself: Arc tolerance. Drawing circles is EITHER a long series of small line segments, OR an "arc". If this problem only effects arcs: you can likely limit your search there.

limit switches convert 6090 2.2k cnc to grbl
You can use NO limit switches with GRBL. Here is some info. But NC is generally a better option because if there is a failure in a wire or connector, the circuit will open and stop the machine.

If I don't use Windows or Mac and only use Linux, will I run into a lot of compatibility issues?
Grbl is a firmware for Arduino based microcontroller dev boards. https://github.com/gnea/grbl/wiki Once programmed you stream the gcode to the grbl controller over USB. It's constrained by the limitations of the Arduino hardware or runs on but it's a great entry point to CNC machines. Note that a 32 bit grbl is under development but pre built control boards are still rare.

building my own laser measurement system for 3d measurements
This may not be a fit, but it may give you ideas for prototyping/software dev. I have prototyped various CNC/optical/medical projects using GRBL GitHub and a simple benchtop frame-gantry setup that I made from 80/20 and steppers.

Is there a way in this software to reverse the direction of X and Y?
If it really is GRBL, you'll find most of the information you need at https://github.com/gnea/grbl/wiki and the $ commands at https://github.com/gnea/grbl/wiki/Grbl-v1.1-Commands
