Re: Absolute and Incremental Toegether

A lot of time is wasted returning A axis back to 0,0 to start the next pass
is the rapid of the 4th axis really-really slow ? what is it's rapid speed ?
repositioning movement is done in feed or in rapid ?
during threading, is the 4th axis used in positioning mode ( degrees / minute ), or like a spindle ( rpms / minute ) ?
if your code works in positioning mode ( degrees / minute ), then have you tried to "start" and "end" at same spindle phase ? so to eliminate the need to reposition the 4th axis between passes ?
Can I combine G90 and G91 on the same command line such that X and Z moves would be in absolute and A moves would be in incremental ?
it is possible to achive this somehow ( by using a soubroutine, etc ), but i don't believe that you really need this trick
i hope that all those questions listed above will light a spark / kindly
