Hi Ghantos,
Screen button codes are stored in the Screenset (typically 1024.set)
Ports and Pins data is stored in the .xml file (typically <your profile>.xml)
The .xml file is stored in the Mach3 folder (as is the screen .set file)
If installing a new version of Mach3 the official word is…
1) Backup the following to the desktop, or even better, a USB drive:
• XML(Profile) – This stores you’re settings for Mach3, if you lose it you will need to re-setup you’re ports and pins, motor tuning, etc.
• Screensets
• Macros/Brains
2) Download the current version of Mach3 from the Downloads & Update page.
3) Install the downloaded version; allow the install path to default to where Mach3 is installed.
WARNING: If you do not backup the files in Step 1, you will lose ALL settings and configurations.
Tweakie.
