Thanks for your responses. It seems I have to give LinuxCNC a closer look. There is a low cost commercial alternative in MACH 3. I guess you have an opinions on that system too? I know it's based on Windows with some kind of realtime extension who doesn't sound too good in ears. My impression is that it doesn't look professional after a brief examination. It also seems to be mainly focused on stepper motor systems who I believe is off topic in heavy duty systems.
My assumption about Tarjectory planning was based on Anders Wallins message as he mentioned some problem with limited look-ahead, I suppose this affects the shape of the calculated path in some cases? / Roger > Date: Thu, 15 Mar 2012 15:18:54 +0200 > From: Anders Wallin <anders.e.e.wal...@gmail.com> > Subject: Re: [Emc-users] Trajectory Planning > To: "Enhanced Machine Controller (EMC)" > >> >> [1] http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TrajectoryControl >> -- >> > > This wiki page has notes on the exact-stop trajectory planner > http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Tp_Notes > > The reasoning and math behind the current G64-blending code in > LinuxCNC is not well documented.. > Improvements for 1) jerk-limited control and 2) better lookahead have > been discussed from time to time but so far the commits/patches have > been missing.. > > Anders ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
