Re: [Emc-users] look ahead---?
last time I had do to something similar, I splitted the last move and inserted my M code between the two moves. Worked well. Le 08/06/2015 08:59, a k a écrit : Hi i think that instead of look ahead for G0 it will be better to have/create new M code (M100 or M(n)) that will: after running on G1 mode and after reading code G0 will move Z up 1 (or some parameter a=..., then move back on the same last trajectory about 0.5 -0.75 or some parameter b=.., then down to initial Z or parameter C=..., and reread last 0.5 =0.75 trajectory motion. this new M code will open new and necessary capability of linux cnc -- for use with welding application. How difficult it will be to create such M code? Any idea direction how to do that? thank you aram On Sun, Jun 7, 2015 at 3:16 PM, a k pccncmach...@gmail.com wrote: hi i am interesting if it will be possible to Linux cnc look ahead 4-5 lines before G0 and then send some signal out? right now i have a working system where when system reads G0 signal going out. now i want to this signal went out like 0.5 - 0.75 of travel before actually system reads G0 when i said 0.5 - 0.75---before G0 machine moves on G1 and when this travel will be around 0.5 - 0.75 before the end of travel i want to signal that indicates G0 go out. thank you aram -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] Look-ahead. Is present in EMC ??
Hallo everybody, I would like to know if EMC manage the look-ahead to optimize the trajectory and if there is a customizing function. I know the acceleration parameter affect the max velocity reached in non linear path, but I would like understand if and how the look-ahead can improve the performance (velocity, accuracy and smoothness) together at accel setting .
