In my setups, others could be different, but angles are absolute using home as a zero reference. Homeing on a rotary however is to the home switch, you can run it 45000 degrees as in this thread, but it will rehome to 0, or whatever offset from the switch is programmed, in under a turn. To answer the question, if you have run it to 720 previously, then a cmd to go 1440, will turn it two more turns and conversely a cmd to goto -1440 will turn it 6 turns in the opposite direction. > > On Monday, September 14, 2020, 4:30:45 AM CDT, andy pugh > <bodge...@gmail.com> wrote: > > On Mon, 14 Sep 2020 at 04:38, Scott Harwell via Emc-users > > <emc-users@lists.sourceforge.net> wrote: > > I found this it might help. > > Scott > > Rapid Rotary > > Along the same lines, there is a filter file here that automatically > converts XY UV G-code to G93 based on which end is bigger. > https://forum.linuxcnc.org/38-general-linuxcnc-questions/35141-a-head- >scratcher-for-me?start=10#120524 > > The only reason I mention this is that it runs automatically as the > G-code file is opened, rather than being a separate application. > (And, to be fair, this isn't an option for RapidRotary as it needs to > be able to query the working radius) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
