[17:12:31] <seb_kuzminsky> back in the way-back-when, in the 3.4-9-rtai days, i had this really vivid daydream about forking myself and having the child process leave the linuxcnc project and go join the rtai project, and i'm reminded of that now...
[17:14:27] <jepler> after a transporter accident, seb_kuzminsky is split into seb_good and seb_evil. One of them works on LinuxCNC and the other on RTAI. Which is the good one, and which one is evil?

[17:41:25] <seb_kuzminsky> i saw that
[17:42:14] <jepler> seb_kuzminsky: which variable was reported as uninitialized? (re your recent commit)
[17:42:35] <jepler> this_instance?
[17:42:53] <seb_kuzminsky> i just asked paolo (of rtai.org) if he'd consider a patch that adds in-tree math source to rtai, which is what memleak did, right?
[17:43:11] <jepler> I would hate to say I had a firm grasp of all that memleak did
[17:43:35] <seb_kuzminsky> jepler: the uninitialized variable was called "m" or "n" before that commit, and "num_instances" or "this_instance" after the commit
[17:44:01] <seb_kuzminsky> jepler: yeah, same here, but it sure seems like a saner approach than what upstream rtai is doing right now
[17:44:16] <seb_kuzminsky> if we got a couple more eyeballs on the implementation something good might come out of it
[17:45:13] <jepler> rtai used to *have* a math library in the tree
[17:46:02] <jepler> some of the files were not distributable. I'm not sure whether that spurred the removal of the whole thing from rtai or not
[17:46:19] <seb_kuzminsky> i dont remember cvs well enough to tell how they got where they are today :-(

[20:23:25] <cradek> the auto filleting that G0G53Z148 wants would be cool
[20:23:59] <cradek> I think my boss8 had that, but I never tried it
[20:24:07] -!- tannewt has quit [Client Quit]
[20:26:05] <cradek> the math would only be medium-hard
[20:26:42] <jepler> G0 X0Y0 / G1X1 / G1 Y1 R.5
[20:26:43] <cradek> calculating that fillet arc is exactly what cutter comp already does when going around an outside corner
[20:26:53] <jepler> one thing I immediately see is that you can't issue the move for G1X1 until you examine the next line
[20:27:02] <cradek> yep that's right
[20:27:03] <jepler> because it might go only to X.5 due to the fillet
[20:27:06] <cradek> yep
[20:27:33] <cradek> heck it might not be able to go at all
[20:27:34] <jepler> and I assume G1 Y1 R1.5 as the third line would just be rejected, the fillet cannot be made that large
[20:27:57] <cradek> yep we're thinking about it the same
[20:28:30] <cradek> you might put the R on the first move?
[20:28:40] <jepler> what would that mean?
[20:28:43] <cradek> at least then you can tell when you have to queue it
[20:28:52] <cradek> at the end of this move the fillet will be
[20:29:15] <jepler> I wouldn't write it that way unless you found one other dialect that also had
[20:29:15] <cradek> I meant your example would be instead: G0 X0Y0 / G1X1 R.5 / G1 Y1
[20:29:26] <cradek> did you find documentation?
[20:29:29] <jepler> no
[20:29:37] <cradek> I don't know which way (they) do it
[20:30:21] <jepler> here's a reference card with G22/G23 "circular interpolation, fillet input CW / CCW"
[20:30:47] <cradek> yeah it'd be too bad that in our dialect you couldn't use R for filleting between arcs
[20:32:27] <jepler> not the same thing, but
http://www.marketotomasyon.com/UserFiles/File/LNC_Manual/T600H/LNCLATHE_Programming_Manual_V04.00.003_ENG.pdf starting on page 21 is interesting
[20:32:37] <jepler> pdf page 21, page number 15
[20:32:40] <jepler> "Geometric input function"
[20:33:19] <jepler> e.g., you can program N01 G01 A(a1) / N02 G01 X(x3) Z(z3) A(z2)
[20:33:35] <jepler> so that your first move is at angle A1, your second move is at angle A2, and your endpoint is x3,z3
[20:33:47] <jepler> and it figures out what intermediate point satisfies the given constraints
[20:33:53] <cradek> jeez
[20:35:12] <jepler> in type 2 you can champfer or fillet, which I think is why I ended up finding this reference in my googling
[20:35:14] -!- ravenlock has quit [Quit: Leaving]
[20:36:07] <jepler> anyway, I notice that in this dialect the chamer/fillet number is on the first line
[20:36:44] <cradek> I can sure see why you'd want that
[20:36:48] <jepler> yeah
[20:36:58] <jepler> then you can immediately output the right move
[20:37:10] <cradek> no you can't
[20:37:18] <cradek> what do you mean?
[20:37:50] <jepler> I wouldn't be surprised if my intuition were wrong
[20:37:51] <cradek> you have to read at least one, possibly several, moves ahead to figure it out
[20:38:07] <jepler> if you have G0 X0Y0 / G1 X1 R.5, can't you just go to X.5 ?
[20:38:16] <cradek> nope
[20:38:34] <cradek> only if you happen to later make a right angle is that correct
[20:39:10] <jepler> OK
[20:39:12] <cradek> g0x0y0z0 / g1x1r.5 / z1 / z0 / x2 / ;haha
[20:40:04] <cradek> oh I wonder if it would fillet in XZ in my silly example
[20:40:13] <jepler> G0 X0Y0 / G1 X1 R.5 / G1 X0 Y.001
[20:40:19] <jepler> was the example I was getting around to visualizing
[20:40:28] <jepler> cradek: depends if G17 is active
[20:40:34] <jepler> in my mental implementation
[20:40:50] <cradek> ooh, interesting mental implementation
[20:40:54] <cradek> I didn't think of that
[20:41:15] <cradek> in your last example it would have to make more than a semicircle?
[20:41:44] <jepler> I think my last example has to be rejected
[20:42:05] <cradek> why?
[20:42:28] <cradek> I guess the final direction of the second line would change
[20:42:40] <cradek> you probably don't want that to happen
[20:42:51] <jepler> right
[20:42:57] <jepler> you want the arc tangent to both the original lines
[20:43:05] <cradek> yeah I agree
[20:43:37] <cradek> so for those two lines, only a very very small R would work
[20:43:42] <jepler> otherwise isn't the problem underconstrained?
[20:43:59] <cradek> because there are two possible arcs?
[20:44:13] <jepler> there are a lot of circles of radius R that touch both lines
[20:44:45] <cradek> I'm not picturing that
[20:48:09] <jepler> https://emergent.unpythonic.net/files/sandbox/circles-touching-lines.svg
[20:48:24] <jepler> all those same-radius circles touch both lines
[20:48:32] <jepler> but the blue one is close to what you mean when you talk about doing a fillet
[20:48:41] <jepler> and it's the tangency requirement that limits you to just that one
[20:48:55] <cradek> oh I misunderstood "touch"
[20:49:33] <jepler> ah you understood "touch" to be tangency, not having an intersection at all
[20:49:41] <cradek> yeah
[20:50:28] <cradek> heh x0 / x1r.5 / x2 could give one of two weird full circles and satisfy tangency with both
[20:50:47] <cradek> trying to think of any other degenerate cases
[20:51:11] <jepler> I think in that case you want the zero-included-angle arc
[20:51:20] <cradek> yeah surely
[20:51:22] <jepler> is there a legitimate case where you want more than a half arc?
[20:51:32] <cradek> not that I've thought of yet
[20:51:50] <cradek> with the requirement that the afterward-line still points in the original direction
[20:52:35] <jepler> g0 x0y0 / g1x1r1 / g1y1 -> you just get an arc, right?
[20:53:23] <cradek> either that, or an error that says you ate up the lines
