[01:24:03] -!- jduhls has quit [Ping timeout: 245 seconds]
[01:25:43] <cradek> yep
[01:28:23] <skunkworks_> ok. so reading your email - I thought it would follow better - but maybe not?
[01:29:43] <skunkworks_> http://imagebin.org/312425
[01:39:51] <skunkworks_> reading comprehension isn't my strong point... I think I was reading 'smooth' as better path following
[01:53:05] -!- cypher_ has quit [Ping timeout: 264 seconds]
[02:10:34] <cradek> if you compare before and after you'll see a big smoothness difference
[02:10:43] <cradek> the old path had pointy spots
[02:12:24] <cradek> (as an aside: I think this path would be easier to make with lines and arcs)
[02:14:37] <cradek> you can barely see it in
http://ibin.co/1OCw5gNzXQBF
[02:15:06] <cradek> at the left top of that topmost loop, you can see an inflection point where it changes from concave up to concave down
[02:15:24] <cradek> it's very evident if you zoom
[02:15:49] <cradek> half the arcs in the path were just totally wrong

[13:46:03] <cradek> although in those cases, maybe I likely won't care about the new topic either
[14:06:34] <zq> i just realized that the estop system communicates with motmod over a non-realtime mpi
[14:06:39] -!- acdha has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
[14:07:23] <zq> could anyone shed some light on how this is not unsafe from a theoretical standpoint?

[14:13:11] -!- skorasaurus has quit [Ping timeout: 252 seconds]
[14:15:22] <cradek> your estop should not rely on talking to software running on a computer for safety
[14:15:44] <cradek> by worrying about whether it's realtime, you are thinking about safety wrong
[14:17:07] <cradek> estop chains should not use semiconductors at all
[14:17:53] -!- skorasaurus2 has quit [Read error: No route to host]
[14:19:26] <cradek> it's convenient if linuxcnc learns that the machine went into estop, but that is NOT a safety issue
[14:20:28] <zq> cradek: then why have realtime at all?
[14:21:10] <cradek> so the machine tool works
[14:21:16] <cradek> that is a very silly question
[14:21:17] <zq> if we're relying on it to generate motion
[14:21:25] <zq> we should rely on it to stop moving too
[14:22:07] <CaptHindsight> E-Stop should work even if the PC and software gets hung
[14:22:19] <zq> whether or not having another layer of external estop as a best practice is a totally different matter
[14:22:25] <cradek> linuxcnc stops the machine just fine in a controlled way, nicely decelerating to a stop, all the time in normal operation
[14:22:38] <zq> cradek: except it doesn't
[14:22:40] <cradek> that has nothing to do with emergency stop
[14:22:48] <zq> as i said, it's done over a non-rt mpi
[14:23:20] <cradek> you are confusing normal operation and emergency stop
[14:23:26] <zq> not at all
[14:23:28] -!- pingufan has quit [Quit: Konversation terminated!]
[14:23:44] <zq> it wasn't difficult to trace how aux.estop is read
[14:23:45] <cradek> estop is done with wires and and a big red button and perhaps some relays
[14:24:01] <zq> i don't think you read anything i wrote
[14:24:08] <cradek> heh, likewise
[14:24:19] <zq> i did, and i responded to each
[14:24:24] <cradek> the estop input to linuxcnc is NOT used to stop the machine
[14:24:33] <zq> it's
[14:24:33] <zq> called
[14:24:35] <zq> "estop"
[14:24:35] <cradek> it is to let linuxcnc know the machine HAS BEEN stopped in an emergency situation
[14:24:45] <zq> every ui has a button named "estop"
[14:25:00] <zq> there's a NMLmsg with substring 'estop'
[14:25:10] <zq> there's an aux.estop
[14:25:13] <zq> it's *estop*
[14:25:31] <zq> there's even a user-enable-out
[14:25:32] <cradek> it's true there are those buttons. it's NOT true that you use the mouse to poke one in an emergency
[14:25:41] <zq> as i said
[14:26:14] <zq> if one relies on it to generate motion, it follows trivially that one would rely on it to stop moving
[14:26:15] <cradek> bbl
[14:27:22] <zq> you're stuck on the fact that { yes, it's a best practice to have a second layer of estop that cuts things off at a lower physical level; }
[14:27:36] <zq> but linuxcnc is fundamentally software, not hardware
[14:27:52] <CaptHindsight> zq: what if the PC gets hung/freezes during motion and you want to stop the machine?
[14:27:59] <zq> CaptHindsight: then that's an issue with the hardware
[14:28:04] <zq> CaptHindsight: or the kernel, even
[14:28:09] <zq> CaptHindsight: and that would be totally out of our hands
[14:28:12] <CaptHindsight> do you want to hit a button on the UI that won't respond?
[14:28:18] <zq> oh man
[14:28:24] <zq> i'm not even talking about the ui
[14:28:40] <zq> the ui, as in emc/usr_intf/*, is completely not part of this conversation
[14:28:48] <CaptHindsight> zq: you're just arguing a point without looking at the entire situation
[14:29:10] <zq> heh, you're kinda like cradek, too attached to the best practice mentality
[14:29:14] <CaptHindsight> zq: please state your point
[14:29:26] <zq> everything i said in scrollback
[14:29:28] <zq> read it
[14:29:43] <zq> { best practice } != { requisite practice }
[14:29:49] <CaptHindsight> and you're like kids that just want to argue a point
[14:30:14] <CaptHindsight> semantics
[14:30:31] <zq> ugh, why would you automatically flame me if you don't understand what i'm saying?
[14:30:35] -!- balestrino has quit [Ping timeout: 260 seconds]
[14:30:50] <CaptHindsight> go ahead and explain
[14:31:07] <zq> ignoring the fact that semantics is in general _everything_, this fundamentally affects how motmod would function
[14:31:33] <CaptHindsight> can you use a software estop to stopm the machine, sure
[14:31:45] <CaptHindsight> what do you really want to know?
[14:31:47] <zq> "can" isn't the point
[14:31:54] <zq> "should" is
[14:32:08] <zq> but there are at least two different meanings of "should" in this context
[14:32:10] <CaptHindsight> philosophy ah
[14:32:21] <zq> and you + cradek are stuck on one
[14:32:41] <CaptHindsight> so use estop vs? to stop the motion
[14:32:53] <CaptHindsight> please don't flame us :)
[14:33:10] <zq> i think that's a request more appropriately posed from me to you
[14:33:22] <CaptHindsight> I disagree
[14:33:35] <zq> in any case
[14:33:52] <CaptHindsight> so which discussion?
[14:34:13] <CaptHindsight> estop vs "what" to stop motion?
[14:34:24] <zq> there's an estop input
[14:34:40] <zq> it isn't a "status update" button as cradek insists
[14:35:03] <zq> even if it were, it'd be more than that purely because emc would be the one generating the motion
[14:35:50] <CaptHindsight> what would you like to use to stop the machines motion?
[14:36:17] -!- lmpyspaceprncs has quit [Ping timeout: 252 seconds]
[14:36:18] <zq> you're essentially avoiding a design best practice and deferring its responsibility to a hardware best practice
[14:36:21] <zq> idk how else to put it
[14:36:35] <zq> CaptHindsight: what do you mean how else?
[14:36:47] <CaptHindsight> so what would you like to use to stop the machines motion?
[14:37:27] <zq> CaptHindsight: i think i've been unwaveringly reiterating that aux.estop must be a reliable source of estop
[14:37:41] <cradek> zq: you asked someone to tell you why it wasn't a safety concern, and I tried to do that, although you had already decided and I think you did not really want the answer to that question - you meant it as a statement. but let's move on and not have an argument about tone. If you want to change the estop communication in and out of linuxcnc to be realtime, that would be fine, maybe even good, but I don't think it would enhance ...
[14:37:47] <cradek> ... safety, which was your original question.
[14:38:00] <zq> cradek: safety as in safe software
[14:38:09] amnesic_away is now known as amnesic
[14:38:25] <zq> safety concern as in concern over how safe this software is, currently
[14:38:43] <zq> not of the unit overall. strictly speaking, that wouldn't be any of the software's business
[14:39:06] <zq> i'll work up a pr
[14:39:19] <cradek> attaching a patch would be great
[14:39:22] <zq> it's not much apart from moving around the emc-enable-in check
[14:39:30] <cradek> great
[14:39:47] <zq> but i wanted to ask here first to see what the reasoning was for the status quo
[14:41:35] <skunkworks> zq - motion is 'realtime' but you still don't depend on it.. you have physical limit switches hooked into the estop loop so if anything happens to the computer - the machine is protected... (and I agree with cradek - estop could be realtime - but I don't know if it is an enhancement)
[14:41:59] <cradek> seems like we'll eventually move everything out of iocontrol/iotask, which is fine with me
[14:42:55] <archivist> there are some sorts of machine where a controlled stop is better than a removal of power
[14:42:57] <cradek> zq: be aware that the estop buttons on the gui can't respond in realtime, whatever you do, because it's a gui
[14:42:59] <zq> skunkworks: plim switches are feedback
[14:43:31] <zq> feedback in the sense of 'status update' but yeah also as critical as estop
[14:43:39] <zq> cradek: of course
[14:43:42] <cradek> archivist: I bet almost every machine is like that.
[14:43:55] <zq> cradek: it's a gorram gui, not realtime in every aspect of its behavior
[14:44:06] <cradek> I don't know what gorram means

[14:46:06] <CaptHindsight> how do you want to measure the safety of the software? Is it safe enough to run a properly designed mill or a teleoperated surgical robot with malpractice lawyers salivation at the sidelines waiting strike?

[14:49:30] <CaptHindsight> software estop vs physical switches....
[14:49:55] <archivist> I think a choice is needed
[14:50:44] <CaptHindsight> I have both on a lathe with a PLC i wired yesterday, the physical e-stop cuts power to the machine and it still takes a couple of seconds to stop moving
[14:54:12] <CaptHindsight> should I add a brake to stop the machine faster? Should the lathe detect when I have possibly snagged a piece of clothing in the chuck and halt within 5 deg of rotation?
[14:54:34] <CaptHindsight> my point is with the software...
[14:55:09] <archivist> I saw a blanking press at a show that was really shifting and I asked about stopping speed, it was within a rev as he then demonstrated
[14:55:10] <CaptHindsight> if you add the realtime vs non-realtime e-stop what do you gain?

[17:20:57] <lair82> pcw_home, I have been looking at motherboards, and have looked at your recommendation of the GA-J1900N-D3V. The only possible issue you know of is a problem with graphics on the regular 2.6 kernel?
[17:23:46] <lair82> Or is the
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157465 ASRock board an alternative as well, I see this one you add your own CPU, I found a 3.2 ghz ,
http://www.newegg.com/Product/Product.aspx?Item=N82E16819113343.
[17:24:07] <pcw_home> Yes no graphics accel with a 2.6 kernel But I hessitate to recomment the Gigabyte unless you dont mind futzing with the BIOS
[17:24:09] <pcw_home> (the BIOS needs to be upgraged to version 3 to boot linux)
[17:24:26] <lair82> That gigabyte is only a 2.0 ghz board
[17:25:00] <pcw_home> 4 core 2 GHz though
[17:25:07] <lair82> I've messed with the BIOS settings some with our current machines.
[17:25:31] <pcw_home> I suspect the 2 core 2.4 GHz J1800s are better
[17:26:32] <lair82> I am not going to say money is not an option, but the money we lose each week restarting the machines and reloading tool tables is no match to spending 200-300 bucks on some hardcore boards and processors.
