[01:48:19] <joe9> when I press "F1" or use the menu item "Toggle Emergency Stop (F1)", nothing happens.
[01:49:00] <cradek> have you tried to hook up estop hardware?
[01:49:15] <joe9> what is that?
[01:49:22] <joe9> i have an estop switch with the gecko.
[01:50:03] <cradek> I'm trying to understand whether you're working on a hardware estop setup, or if you just want pretend (software) estop like in the sim configs
[01:50:43] <joe9> cradek: i am sorry for doing this on both channels. will switch to the #linuxcnc about this discussion.
[01:50:48] <joe9> hope that is not a bother.
[01:50:54] <joe9> and, very sorry for doing that.
[01:51:17] <cradek> ok, I'll stop fishing for information and just let you explain what's going on
[01:51:50] <cradek> and go start my laundry

[23:48:44] <ysli> cradek: hello
[23:49:33] <ysli> I got the preliminary implementation for "Seamless Blending (SMLBLND)"
[23:49:41] <ysli> the result is good
[23:50:01] <micges> ysli: hi
[23:50:01] <ysli> for the axis.ngc demo
[23:50:08] <micges> what is it?
[23:50:18] <ysli> there are a lot of G3 segments
[23:50:36] <ysli> their tangent vectors are smooth
[23:51:23] <ysli> however, with the original blending algorithm, we have to decelerate for each of them
[23:51:44] <ysli> as a result, the motion is not smooth for those segments
[23:52:48] <micges> you mean decreasing velocity between arc->arc ?
[23:53:15] <micges> I mean not decreasing
[23:54:25] <micges> ysli: anyway, cool!
[23:54:26] <ysli> micges: yes, not decreasing for line->arc, arc->arc, arc->line, if the inward and outward tangent vector for them are identical
[23:55:09] <micges> I saw that many times with our plasma with linuxcnc
[23:56:44] <ysli> By calculate the "centripetal acceleration" for those segments, if it's within limit, then seamless blend the two segments
[23:57:13] <micges> ysli: take a look at this: http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=commit;h=b8eb1be3d82626a5f0e5da88a483c3b496f2f3d8
[23:57:21] <ysli> micges: do you mean this kind of blending is already there?
[23:57:52] <micges> no
[23:58:02] <micges> read commit
[23:59:02] <ysli> I see
[23:59:23] <micges> did you niticed someting simmilar?
