We've had this discussion within MadCAM users, the guys running older machines (non converted or with old drivers) loses speed and sometimes the G-code comes out too big for the machine memory. So there's a need for it,
Frank Tkalcevic, that's the guy who made the g1ToG23 script. Really clever little thing. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinesToArcs Here's the original mail from June 2013: *It will take a gcode file (only tested with Slic3r output) and convert themany short line segments back to arcs. It can make a huge difference toprint speed and file size if there are lots of arcs.It's slow, but has been reliable over the last couple of months.Frank* If you search the mail archive <http://comments.gmane.org/gmane.linux.distributions.emc.user/44529> you'll find the mail thread. 2015-03-26 1:40 GMT+01:00 andy pugh <bodge...@gmail.com>: > On 26 March 2015 at 00:33, Gregg Eshelman <g_ala...@yahoo.com> wrote: > > > Would make the cut faster and smoother instead of doing a lot of very > > short straight cuts. > > Possibly not, as the trajectory planner already does that (to within > the limits of the blending tolerance). > > However, I think I have heard of software that can do the same thing. > > You can draw an arc through any three points, but there is no > guarantee that successive arcs generated the same way will be > tangential to each other, so there needs to be some clever > manipulation to make the arcs as big as possible to see the potential > advantage. > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto > > > ------------------------------------------------------------------------------ > Dive into the World of Parallel Programming The Go Parallel Website, > sponsored > by Intel and developed in partnership with Slashdot Media, is your hub for > all > things parallel software development, from weekly thought leadership blogs > to > news, videos, case studies, tutorials and more.
