freelaser engraver software

A controller software program serves as a communication path between your computer and the CNC machine.

It reads the G-codes created using CAM software to run the stepper/servo drivers on CNC machines.

But without firmware, the CNC controller cannot read G-codes.

Hence, it is necessary to flash the CNC controller board with firmware that allows it to communicate with the controller software.

GRBL (pronounced gerbl), is a highly popular firmware that supports CNC configurations.

GRBL is the most popular open-source firmware which is flashed mostly onto the Arduino-based controller boards of CNC machines.

This firmware lets you control the 3-axis motion of CNC machines using a PC via USB interfacing.

It is easy to set up and has simple configurations that make it the preferred choice for beginners and hobbyists. However, it can only control a maximum of three axes.

There are two types of control software for CNC, one simply passes on the G-code to the controller onboard the CNC router and are called the G-code senders, like UGS.

1. Universal Gcode Sender (UGS)

Best Free GRBL Control Software (UGS)

Universal Gcode Sender (UGS) is a free, open-source software used to interface with CNC controllers flashed with GRBL firmware.

It is a G-code sender that simply pushes the G-code from your computer to the controller and the processing is done by the controller.

UGS software is available in classic and platform versions that you can download from its GitHub page for free.

It is written in Java to support multiple platforms, such as Windows, macOS, Linux, or Raspberry Pi OS.

Although both versions have the same robust backend, the platform version is the most recent release that has undergone some UI tweaks and has more features than the classic version.

UGS lets you import standard G-code produced from any CAM software and edit it to run your CNC machine.

If your CNC machine has an Arduino-based control board, UGS is the high-performance CNC controller software for it.

The controller state box of this software has several toolboxes, like reset zero to convert the current coordinate to a new origin and soft reset to reboot the CNC controller.

UGS has good documentation support for its users. On the GitHub page of UGS, you will find instructions from installation to making your first cut using CNC machines.

It is highly popular amongst hobbyists and you can also find many tutorials on YouTube to get you started with UGS software.

This software accepts standard G-codes. However, its serial port server can not read G-codes exceeding 25,000 lines. It is because the planner buffer of the serial port server maxes at 25,000 lines.

ChiliPeppr has Maker Forums online community of active users where you can discuss CNC machine control-related issues and submit bugs for troubleshooting.

5. OpenCNCPilot

Best GRBL control software (OpenCNCPilot)

It is a free, open-source, G-code sender software capable of scrutinizing user-defined regions using an auto-leveling feature. It then creates a heightmap that can fit the toolpath of your design.

OpenCNCPilot software uses basic bilinear interpolation between the nearest four points for auto-leveling,

Once the heightmap is ready, this software wraps the toolpath all over the curved surface. Now you can run your G-code file normally.

This feature is handy in PCB milling (isolation milling) with V-shaped engraving bits, where any deflection in the Z-direction leads to narrow or wide traces.

OpenCNCPilot software is written in C#. Hence, you can only use this software on a Windows OS PC. Make sure to use the latest version of GRBL firmware 1.1 to use this software; otherwise, it will not work.

If you face any issue regarding using this software, you can describe your problem and share relevant images on the GitHub Issues tracker of this software page to solve your issues.

8. LaserGRBL

Best Free GRBL Control Software (LaserGRBL)

If you are looking for free, open-source, laser-focused GRBL controller software, then LaserGRBL is probably what you want.

This software is considered one of the best G-code sender software for hobbyists working on laser cutters and engravers.

You can use this software only on a PC running on Windows. But, using the Wine 5.0 and Wine Mono 4.9.4 program with the Gdiplus Windows DLL file, few users have managed to run this software on Linux PC.

This software has a clutter-free UI that shows job preview, estimated job time, and real-time position of the laser head

. You can also set buttons to quickly execute the custom actions, such as jog speed and image position.

I liked its unique color scheme that is fully optimized to be used while wearing safety glasses.

This optimization lets you shift your gaze from the work bed to the computer screen without having to remove the glasses.

This software also offers detailed alarm and error code decoding for GRBL. It helps in quick and easy troubleshooting.

Frequently Asked Questions (FAQ)

Why sometimes does my GRBL controller software shows offline and would not connect to the CNC machine?

Working on long G-code files may switch off serial ports of PC. So, make sure to refresh your PC to bring it out from sleep mode.

Which type of arduino boards should I consider to flash GRBL firmware for motion control of my CNC machine?

GRBL firmware is best suited with ATmega328 type Arduino boards, such as Uno, Nano, and Duemillanove.

How can I build a CNC machine without Arduino board?

Instead of an Arduino board, you can consider a Raspberry pi 4 board to build your CNC controller board and PlanetCNC controller software that runs perfectly with RPi boards.
