How to install Turn G-code on Linux
A step-by-step guide. Takes 2–3 minutes.
What you need
| System | Debian 11 or newer, Ubuntu 20.04 or newer and compatible distributions (Linux Mint etc.), 64-bit (amd64). ARM processors (e.g. Raspberry Pi) are not supported. |
| Screen | From 1024×768 taking system scaling into account, 1280×720 or more recommended. Use the monitor's native resolution. See "Screen and scaling" below. |
| Disk space | About 20 MB. |
| Internet | Needed 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. |
| Rights | Installing requires the administrator password (sudo). |
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.
| Screen | Scale | How it looks |
|---|---|---|
| 1024×768, 1280×720 | 100% | Compact view: slightly smaller text, everything fits |
| 1366×768 | 100% | 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: GNOME, Ubuntu: "Settings" → "Displays" → "Scale". Xfce: "Settings" → "Appearance" → "Fonts" → DPI (96 is 100%, 120 is 125%, 144 is 150%). Other desktops have a similar option in the display settings.
Restart the program after changing the scale or resolution.
Installation step by step
1Download the package
Download the file turnmaster_1.0.0_amd64.deb only from this website. It is usually saved to your Downloads folder (~/Downloads).
2Install the package
The easiest way is the terminal. Open a terminal in the folder with the file and run (the leading ./ before the file name is required):
sudo apt install ./turnmaster_1.0.0_amd64.deb
Alternatively: double-click the file in your file manager and press "Install" in the software installer that opens.
3Start the program
Find Turn G-code in the application menu (Engineering / Utilities) or start it from the terminal:
/opt/turnmaster/turnmaster
4First launch
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". The licence is bound to this computer.
How to verify the checksum (optional)
To make sure the file was not altered, run in the folder with the file:
sha256sum turnmaster_1.0.0_amd64.deb
The result must match this value (SHA-256 of version 1.0.0):
819d61840e781f220dbad20e8976e716b08c802b1b249c77d47c64382fe5ce5b
If something goes wrong
- "dpkg: dependency problems" error. Run
sudo apt --fix-broken install, then repeat the installation. - "Unable to locate package" with
apt install. Check that you are in the folder with the file and put./before the name. - The window does not fit on the screen, or everything is too small. Change the display scale (see "Screen and scaling" above) and restart the program. A screen of at least 1024×768, taking scaling into account, is required.
- The program says an internet connection is needed. A connection is required on first launch or after activating a key; later it can work offline; to pick up a subscription renewal, connect at least once a month.

How to uninstall
sudo apt remove turnmaster
Your licence and settings stay in your profile folder (~/.turnmaster) and are not removed with the program.
