[Emc-users] axis 'wrap'

2008-04-17 Thread Stuart Stevenson
Gentlemen, While reading the config files for the Mazak I saw the section where you set up the spindle to 'wrap'. I would like to see that same capability for the rotary axes. The C axis on the 5axis sim would work good with the 'wrap' function. This would work good on a machine I have.
