If you haven’t yet, you’ll need to download the necessary version of gSender for your operating system. Downloads for primary systems as well as all other available builds are available on the main gSender page:

Windows Install

You may run into a security warning from your computer when you download the .EXE file. This can be bypassed by selecting “See more.” You can choose to keep the download, so that it can continue to run.

Microsoft Edge Users: If you are having difficulties downloading gSender when using Microsoft Edge, follow the instructions here or watch the video here.

Once you’ve downloaded the EXE file, double-click to run it. gSender isn’t yet set up to pass security checks so you’ll have to allow it to run manually by clicking ‘More Info’ and then clicking ‘Run anyway’. If you don’t feel that you can trust gSender, then no pressure to use it; we’ll have this setup later on.

If the “More info” option isn’t available, it could be that Windows is fully blocking installation. This can be fixed by going to “App & browser control” and switching “Check app and files” to “Warn” or “Off” just for the installation of gSender. You can always turn it back on afterwards.

With permission to run, you should be met with a license agreement. gSender is provided “as is” which means there’s no expectation that it’ll run your CNC perfectly – especially as it’s still in very active development. We want you to understand this before moving forward. If you agree, you’ll be able to choose your install options from there (who to install for and where) and then begin installing.

Install completion with be indicated by a completion screen. If the ‘Run gSender’ box is checked off you should be able to click ‘Finish’ and be greeted with a splash screen followed by the full program. If not, you can always open to program manually after install.

Mac Install

Once you’ve downloaded the DMG file, double-click to run it. A window will popup that will look like the one below. Click and drag the gSender app and let go the applications folder to save it to your Mac.


Navigate to your applications folder on your Mac and the gSender program should be there and ready for use.

If you are having issues installing gSender on your Mac, follow these instructions to open blocked apps. 

Pi Install

For getting gSender set up on a Pi (not headless), you’ll want to:

  1. Download the AppImage
  2. Right click and go to permissions tab
  3. Make sure “executable” permission is set on the file
  4. Run the program

Upon running, you may get an initial error window filled with lots of of text. This is just a prompt from the updater which is attempting to find a new version of the program. You should be able to click through it and access gSender as normal.

Sizing for Smaller Screens

As of yet, gSender can size responsively but only to a minimum point. Because of this, some Pi users might find gSender isn’t fitting their screen properly. This can be accommodated on most pis by:

  • Click the pi icon on the top right
  • Preferences -> Screen configuration -> Configure -> Screens
  • Click HDMI-1 (or whichever screen that is connected to the pi)
  • Then click Resolution -> 1280×1024

This will allow gSender to show on your screen fully without it being cut off.

gSender Updates

Most systems are set up so that each time gSender has a new update available, there will be a notification on the program that allows you to quickly download the latest version. If you’re not receiving these update notifiers, your system is not yet supported but you should still be able to download the newest version manually and install it over-top of the old version.
