Yes, that is how the demo is set up, but the actual sequence is set by a G-code subroutine, so is reasonably easy to change. All the carousel module does is interpret carousel position feeback and issue motor movement commands for a tool carousel. Everything else is handled elsewhere. In the examples it is by G-code, but it would interface with Ladder just as easily. As you need to move the head up and down and issue spindle speed commands I think that you will find G-code more convenient, moving the head from ladder is more difficult. Also, that example includes spindle orient. You might want to consider a spindle orient commands rather than a spindle start command. The docs say that M19 is limited to R-values of 0-360 but you can force movement in one direction or the other. I think that a string of 180 degree moves could be used to unscrew the drawbar by a requested amount. It also has a built-in timeout in case things stick. The advantage would be that you could ensure that the drabar thread remained engaged. My milling machine has a sturdy cast cap over a clllar the drawbar on the horizontal spindle. If you unscrew far enough it actively ejects the taper. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
