Actually, with enough pid.s.Pgain, I've another ghost of an idea as I need it to be as stiffly regulated at 100 rpms as it is at 1000 rpms. So my studies and experiments today will be to see if that faint idea can actually be used. I think I can get 2 or 3 hours to play I hope. > > Thanks > > > Rick > > > > ------ Original Message ------ > From: "Gene Heskett" <ghesk...@wdtv.com> > To: emc-users@lists.sourceforge.net > Sent: 9/18/2014 7:50:48 AM > Subject: Re: [Emc-users] Question on "gearchange" use? > > >On Thursday 18 September 2014 07:19:10 Rick did opine > > > >And Gene did reply: > >> Hello Gene, > >> > >> Here is what I have in my HAL files for my machines, all three of > >> my turning centers have 2 speed transmissions on the spindles. > >> > >> Just holler if its gets fuzzy, there is a lot going in my file, > >> > >> > >> Thanks > >> > >> > >> Rick > >> > >> > >> > >> ------ Original Message ------ > >> From: "Gene Heskett" <ghesk...@wdtv.com> > >> To: emc-users@lists.sourceforge.net > >> Sent: 9/17/2014 11:29:21 PM > >> Subject: [Emc-users] Question on "gearchange" use? > >> > >> >Hi all; > >> > > >> >As I have a 2 speed backgear head on this toy of mine, I'd like to > >> >make use of this module to actually double up the low speed power. > >> > > >> >But I've no clue where to insert it.
