Cannot figure out why Universal GCode Sender won't connect to my Arduino Mega 2560. Any idea what's wrong?? Details in comments
I just tried with GRBL-mega from the link below and it connected without any problems: https://github.com/gnea/grbl-Mega/releases/tag/v1.1f.20170802

Arduino 2560 can’t upload Grbl
are you uploading normal grbl or grbl for arduino 2560? https://github.com/gnea/grbl-Mega

Grbl on Creality 8Bit Board
You could use https://github.com/gnea/grbl-Mega or https://github.com/fra589/grbl-Mega-5X And you need to know the pin usage of your board, to setup the config.h file

I need some help programming grbl.
Specifically, I am using grbl-mega and a ramps board "because it's what I have on me" and need to modify the code a little to operate a laser and I can't even get the Arduino ide to compile stock grbl, and had to use xloader and a precompiled version of grbl. If someone can either make me or tell me how to make a .hex file with this modified code I would really appreciate it. Here is the information you will need to understand where to put the code, just scroll to the post with the code written on it.https://github.com/gnea/grbl-Mega/issues/55 and here are the grbl-mega files.https://github.com/gnea/grbl-Mega

Pen plotter
Probably yes, it seems to use a Mega 2560, so you could use https://github.com/gnea/grbl-Mega or https://github.com/fra589/grbl-Mega-5X

Beginner: 4 axis stepper motor help
Alternative is (and you still need limit switches) is load the mega with some form of GRBL. This makes your mega into a CNC machine which is entirely co-ordinate based and you control the movement with GCODE.

Could I use a RAMPS 1.4 3D printer controller board for a CNC mill with GRBL?
Next is to download the grbl branch you want:Just 3 axis: https://github.com/gnea/grbl-Megaor up to 5 or 6 axis: https://github.com/fra589/grbl-Mega-5X

- Potreste aiutarmi a capire il modello di questa macchina ad incisione? (non è laser)

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
