This is an extension of the 'slow gcode' thread. The work that Robert has done on the TP are now in the beta stage. (has been for a little while - but I forgot to post anything about it on the user list.. :( )
I think the best way forward is to look at the thread on the forum and follow the directions to build it. (if you are wanting to test the new TP) http://www.linuxcnc.org/index.php/english/forum/10-advanced-configuration/27368-new-trajectory-planner-testersprograms-wanted currently the new TP improves the path velocity (by read ahead) if the segments are Line-line Tangent line-arc Tangent arc-arc Here are a couple screenshots.. This is showing a simple program (one rogge had posted a while back with an entry/exit move ) % (1" square with rounded corners) G90 G54 G20 g64p.001q.001 G0 X0 Y.25 Z.25 z0 G1 Y.75 F999 G2 X.25 Y1 I.25 G1 X.75 G2 X1 Y.75 J-.25 G1 Y.25 G2 X.75 Y0 I-.25 G1 X.25 G2 X0 Y.25 J.25 g0z.25 M30 http://electronicsam.com/images/KandT/testing/screenshots/Screenshot%20from%202014-01-26%2014:53:00.png This is running new TP strait G64 - peaks at 222ipm http://electronicsam.com/images/KandT/testing/screenshots/Screenshot%20from%202014-01-26%2014:34:21.png Old TP running strait G64 - peaks at 159ipm http://electronicsam.com/images/KandT/testing/screenshots/Screenshot%20from%202014-01-26%2014:36:20.png This is the new TP running G64P.001Q.001 Still peaks at 222ipm - just slows a bit at the sharp corners. http://electronicsam.com/images/KandT/testing/screenshots/Screenshot%20from%202014-01-26%2014:42:11.png Old TP running G64P.001Q.001 - slows down a lot more.. (I think mainly because the parabolic blend needs to be slowed down quite a bit compared to the circular blend to match the path) http://electronicsam.com/images/KandT/testing/screenshots/Screenshot%20from%202014-01-26%2014:40:36.png Thanks all goes to Robert - he has coded this all on his own..
