There are two ways discussed here to set the rotation of labels i.e. in the LabelMaker settings or in EzyNest.
In LabelMaker, under Settings > Options, enable the 'Allow label rotation' check box.
You can also 'Reverse rotation direction' or 'Rotate by extra angle', as shown.
EzyNest23 provides an option to allow the label image files to rotate (to suit the position of the parts on the nest).
This can be done under Setup > Preferences (click on image). On the AutoTP tab, under Labels, use the 'Alternative Compass Orientation' check box, as shown.
You can also use the 'Alternative Compass Orientation' check box, as shown, on the Machine Setup > Labels & Output tab.
