Formulating a macro to locate the Z axis at a specific height is quite helpful. You can override feeds and speeds in other control software too, but the 1% and 10% buttons are pretty convenient in cncjs (as opposed to entering numbers).Ĭncjs is compatible with making useful macros such as corner probing, hole probing, semi-automatic tool change, and more. One of its widgets allows you to override feeds and speeds mid-operation, by 1% or 10%. But, if the software runs slow you can turn it off.

It has a visualizer that reads g code commands and simulates the toolpath.

It just uses the browser’s network protocols to run, since your GRBL is on a serial port.Ĭncjs has many widgets. You need a browser to run cncjs, but it doesn’t require an internet connection.

You can also add a touchscreen if you prefer, and control the CNC machine on sight without connecting a computer. Firstly, Raspberry Pi replaces your computer so you don’t need a dedicated laptop. Though, if your CNC doesn’t have Raspberry Pi, cncjs is still one of the best GRBL software, competing closely with UGS.Īdding Raspberry Pi to a CNC machine offers several benefits. Jogging has the same number of steps on all axes (unlike UGS).Ĭncjs reads up to 400000 lines of g code.Ĭncjs is the best GRBL software if your CNC machine has a Raspberry Pi. Operating Systems: Windows, MacOS, and Linux.Cncjs – Best GRBL Software for Raspberry Pi You can also import your GRBL settings from a file.Ģ. Setting up GRBL is also pretty easy with UGS – it has a list of GRBL settings along with what they do. It has no external dependencies (for example, external browsers or runtime libraries). UGS is compatible with Windows, macOS, Linux, and Linux ARM. It has always been robust and reliable in working with GRBL, never running into issues or bugs. UGS is open-source and free control software. However, this requires compensating by pressing many times when jogging the X and Y axis.Īnother cool feature is you can jog your CNC machine using a joystick or a gamepad with UGS. Therefore, you should use small settings in other GRBL software to stay safe. If we tell the Z axis to move in large steps like the Y axis, it risks jamming into the board, and can damage your stepper motor or its driver. This feature is useful since we move the Z axis at short distances. Pattern and toolpath created in Fusion 360 and used UGS to send the gcode to the CNC machine. But, UGS has one setting for the X and Y axes – and another for the Z axis. The control software has jog settings that specify how much GRBL moves your machine with each button press. So, if you press the button by mistake, or realize that the machine is crashing into an obstacle, you can’t stop GRBL during the jog. When you press the button, GRBL stops listening to any other command until it has covered the distance. Let’s assume that you’ve set your control software so that GRBL moves the CNC 50mm (about 2”) every time you press the jogging button. However, GRBL doesn’t listen to your jogging commands in real-time – GRBL only moves in increments, and you can’t stop it mid-travel. Some controllers jog in real time, and stop moving the CNC machine as soon as you tell them to stop (or if you stop sending them signals to move). However, GRBL is not the best for jogging – with serious shortcomings. Jogging is when you manually move your CNC machine by pressing a button (on the keyboard or a joystick, etc). I’ve only seen this feature in UGS and consider it highly helpful for my projects.

UGS has different distance increments for jogging the Z axis. It’s robust, and it has all the basic widgets you need to interact with GRBL – but UGS also has some other unique and useful features. The Universal G Code Sender (UGS) is one of the best GRBL software for many reasons. UGS is not the best option for Raspberry Pi (though UGS is compatible with it).
