FIFTY LINETurn G-code

How to install Turn G-code on Windows

A step-by-step guide with pictures. Takes 3–5 minutes.

What you need

WindowsWindows 7 SP1, 8.1, 10 or 11, 32-bit or 64-bit.
ScreenFrom 1024×768 taking system scaling into account, 1280×720 or more recommended. Use the monitor's native resolution. See "Screen and scaling" below.
InternetNeeded on first launch (a key for the generators is downloaded once), to activate a licence key, and at least once per paid period (once a month for the subscription) to pick up the renewal. Between connections the program works offline.
RightsInstalling requires administrator rights.

Screen and scaling

The program's windows adapt to the screen: on a small one everything becomes more compact, on a big one larger, and the tool-path preview takes the full height of the window. System scaling is supported too, and the text stays sharp.

ScreenScaleHow it looks
1024×768, 1280×720100%Compact view: slightly smaller text, everything fits
1366×768100%Normal view
1920×1080 (Full HD)100–150%Normal or large view, tool-path preview uses the full height
2560×1440 (2K)100–150%Larger text, big preview area
3840×2160 (4K)150–200%Large and sharp

The main rule: the resolution divided by the scale should be at least 1024×768. For example, Full HD at 150% gives 1280×720, which is fine. A 1366×768 laptop at 125% gives only 1093×614, which is too tight: set it to 100%.

Everything too small? Increase the system scale (125% or 150%). Window does not fit? Lower the scale to 100%.

Where to change it: Right-click the desktop → "Display settings" → "Scale".

Restart the program after changing the scale or resolution.

Installation step by step

1Download the installer

Download the file TurnGcode-Setup-1.0.0.exe only from this website. Your browser may say "This file is not commonly downloaded" or "Couldn't download securely": choose "Keep" or "Save anyway" (see below for why).

2Run the file and confirm the Windows warning

Windows will show a window about an unknown publisher. This is expected: the installer is not yet digitally signed (explained below). Click "Run".

On Windows 10 and 11 you may instead see a blue window "Windows protected your PC": click "More info", then "Run anyway". Windows will then ask for permission to make changes: click "Yes".

7First launch

Open Turn G-code. A 15-day trial starts. The program downloads a key for the generators once, so an internet connection is needed. To continue after the trial, enter your licence key in the "Licence key" field and click "Activate".

Why does Windows warn?

The warning appears for programs without a publisher's digital signature: Windows cannot verify who released the file. We have not bought a signing certificate yet, so Windows says "unknown publisher". This does not by itself mean the file is dangerous, but it does mean Windows could not check it. That is why you should:

How to verify the checksum (optional)

Open PowerShell in the folder with the downloaded file (in File Explorer: File → Open Windows PowerShell) and run:

Get-FileHash .\TurnGcode-Setup-1.0.0.exe -Algorithm SHA256

The result must match this value (SHA-256 of version 1.0.0):
