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.

- Potreste aiutarmi a capire il modello di questa macchina ad incisione? (non รจ laser)
- Has anyone programmed a professional CNC or Laser cutting machine with PLC technology? What are the key points about it?
-
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.

How to calibrate a GBRL CNC machine ?
The gnea/grbl GitHub Getting Started page spells all that out.

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

Is it possible to delete the boot loader on a SKR 3 EZ?
Take a look at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader -- it may help. It's not only for the larger boards.

SKR 3 EZ Bootloader FW
However, I couldn't manage to find the original bootloader for this chip. I found this : https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which is very interesting for many older BTT controllers, but not the SKR 3 EZ.

Bootloader broken on 4.2.7 board?
If you want to investigate, you might start by looking at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader

Upgrade fw without sdcard ?!
The only other way is to use a little programmer such as an ST-Link, which looks similar to but is different from the little USBasp programmers that can be used for 8-bit boards. An ST-Link can flash firmware directly, but it's not as simple as using the SD card. See, for example, https://www.youtube.com/watch?v=7O_ZOdnM0SU and https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader

My micro sd card reader on my btt seems to be broken can I use a usb isp to update the firmware instead?
For LPC based boards this may help. It seems to allow flash over USB.

SKR Mini E3 v2.0 doesn't update its firmware even if the firmware.bin change to firmware.cur
It doesn't sound like an EEPROM fault, because that only affects various settings, not what functions and codes it supports. It sounds like something is wrong with the bootloader, eg it's reading the firmware file but not storing it. If nothing else works, is it worth getting a little STLink in-system programmer and reinstalling the bootloader and firmware completely? There's a link at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which should be helpful if you want to try that.

I think I bricked my skr 1.4 turbo
(If all else fails, you can try reflashing the bootloader - something on this page may help you.)

SKR V1.4T AGAIN!
Technically, it's possible to use a programmer to update the firmware, and I've seen descriptions of how to do that with various small programmers. Here's an example. Perhaps a google search will find more information, given that it does exist. People have used that technique to read and (re)load bootloaders and firmware.
