If you have a GCode device and you’re using a dedicated rotary axis (the A axis), the value is displayed as ‘degrees per rotation’, meaning the number of d…

Mm per revolution is basically the distance required to rotate the roller one full turn. You still need roller diameter to then determine how much linear travel is made for one rotation.
