I was trying to create a number of custom temperature towers for some oddball filaments and discovered that the Tower Label placed at the base of the right column is limited to 3 characters in the version I'm using. I'm using Cura 4.13.1 for these tests, with AutoTowers Generator 2.7.2, and I assume that's using the QT5 folder rather than the QT6 folder.
The corresponding UM.toolTip in Resources\QML\QT6\TempTowerDialog.qml says "This must be four characters or less." Which is fine because I (only) need four characters for "PETG", "PA12", "PLA+" and so on, and it's obvious there's no room for more. In that file, the lines above are
Layout.preferredWidth: numberInputWidth
validator: RegularExpressionValidator { regularExpression: /.{0,4}/ }
However, in the QT5 folder, they're
Layout.preferredWidth: numberInputWidth
validator: RegExpValidator { regExp: /.{0,3}/ }
I've edited my copy to {0,4}, but can you change that in the next release, please?
