[00:03:08] <furrywolf> one study grafting peppers onto tomatoes got a 100% success rate out of 12 plants
[00:03:31] <furrywolf> whoops, 92 of 92 plants
[00:03:35] <furrywolf> that's pretty impressive
[00:04:32] <furrywolf> I am totally going to go pick up some tomato starts and try this.
[00:08:31] <furrywolf> bbl, need to run errands. (no, not picking up tomatoes - they won't have starts in for a bit)

[01:14:45] <tjtr33> pcw_home, i saw the latency tests, thx, i must have a bad unit, >360uS with no isolcpus. 4glxgears and 1 mp3 from local SATA drive. same seller AFAIK
[01:15:58] <tjtr33> bthx, i'll try once more, reset bios to stock and try again
[01:16:00] <furrywolf> did you reset bios to factory defaults?
[01:16:01] <tjtr33> thx
[01:16:14] <furrywolf> bah, a second late... :P
[01:16:20] <tjtr33> yes i believe i tried it already, but will try agai again again
[01:17:41] <furrywolf> are you running off a real drive or off the usb thumbdrive?
[01:17:52] <furrywolf> (some boxes seem to go out to lunch reading usb)
[01:18:51] <tjtr33> sata WD 160G
[01:19:34] <furrywolf> ... on a completely and totally unrelated topic, I want http://www.wetforher.us/dildo-lesbian-sex-toys-all/34-strap-on-harness-dildo-multicolor-sex-toy-lesbian-.html (safe for work unless you look closely). Just because it looks so much like art that I could leave it out on the living room table and most people wouldn't notice it. lol
[01:19:45] <furrywolf> so a real drive.
[01:20:02] <furrywolf> 360us is... horrible.
[01:20:18] <furrywolf> I've never seen or heard of numbers that high.
[01:20:22] <tjtr33> i have it all logged at... https://www.dropbox.com/sh/n95e1h9qlj09cp2/AAA4g5Td3eGlicFJWh4cRWf4a?dl=0
[01:20:36] <tjtr33> and screen shots of some of the results
[01:21:15] <tjtr33> eh? weird post
[01:21:22] <tjtr33> ot ok
[01:22:20] <furrywolf> oh, so the sata drive is external?
[01:22:48] <tjtr33> internal
[01:23:00] <furrywolf> ah
[01:23:08] <tjtr33> i gonna go try it now, reset bios and run latency-histogram
[01:24:41] <furrywolf> somehow dropbox has broken... it loaded, all the thumbnails loaded, I viewed one image... now all the thumbnails are empty grey boxes and stay that way even reloading the page.
[01:25:18] <furrywolf> try turning off idle power saving
[01:26:55] <furrywolf> and try without the usb wifi adapter
[01:27:22] <furrywolf> I haven't had this problem with linuxcnc specifically, but I've had boxes that seriously went out to lunch when usb was involved
[01:27:42] <MacGalempsy> :) good evening

[01:53:12] <tjtr33> i will try the latency test after this cooks a while. i just re-looked at pcw's results, make s me wanna buy another unit ( not sellers fault , i suppose)
[01:53:45] <tjtr33> furrywolf, i didnt think pcw did anything at all to his syem, lemme re-read
[01:54:38] <tjtr33> i dont see he said anything about what he did , the screen says no isolcpus tho
[01:55:03] <tjtr33> whats all the unsymmetric stuff i get?

[02:09:44] <MacGalempsy> the voltage is correct, so now its just looking at the code again
[02:11:03] <tjtr33> red light = >18V? green light = <2?
[02:11:33] <tjtr33> (24V negative logic)
[02:11:52] -!- scooty_puff has quit [Client Quit]
[02:11:59] <MacGalempsy> yeah. red is 19.6
[02:12:15] <MacGalempsy> green is ~1.0mV
[02:12:34] <tjtr33> now if you get the device to really turn on, you oughtta get green and <2V
[02:12:47] <tjtr33> me, i'm out for dinner, good luck!

[04:21:35] <pcw_home> re: dc7800SFF, I just turned any obvious power saving options inthe BIOS (and set the fan about 1/2 way up)
[04:21:37] <pcw_home> Not only does it get decent RTAI latency, Preemt-RT latency (3.18.7-rt2) is good enough to run
[04:21:38] <pcw_home> Ethernet I/O cards at a 4 KHz servo thread sure you dont have a bad hard drive or something like that?
[04:21:40] <pcw_home> your plots are weird :-)
[04:21:48] <pcw_home> turned-off
[04:22:48] <Rab> pcw_home, I booted off USB thumbdrive and got significantly better numbers than from internal SATA. Can't figure that out.
[04:22:58] <Rab> But mine wasn't that bad either way.
[04:23:25] <_methods> 6gb/s sata headers or 3?
[04:23:41] <pcw_home> Im using a SSD, that may make a difference
[04:24:15] <Rab> I'm using a 320GB Seagate Barracuda, pretty old drive these days.
[04:24:55] <pcw_home> drive errors can cause latency problems
[04:25:14] <Rab> Hmm, I should check SMART info.
[04:26:30] <pcw_home> for Ethernet its significantly better than my (similar vintage ) desktop at home
[04:27:08] <pcw_home> maybe because of the PCIE intel 1G MAC on the MB
[04:27:53] <pcw_home> ping times are even better than my H97 MB with intel MAC
[04:28:37] <pcw_home> (in both cases you need to use ethtool and turn off IRQ coalescing)

[04:31:12] <adoyle88> Hello everyone. As some of you know, in working on a CNC tubing bender. I've got a dumb question about hal and linuxcnc.
[04:31:26] <pcw_home> BTW that latest histogram has + and - peak values recorded
[04:32:00] <tjtr33> ah some new revision
[04:32:02] <tjtr33> my caxis showed up, damn heavy, they shipped a cast mounting plate and the Z bellows
[04:32:24] <tjtr33> adoyle88, ask the Q
[04:33:01] -!- nerdfiles has quit [Read error: Connection reset by peer]
[04:33:47] <adoyle88> I'm using an optical encoder to count degrees bent. I've successfully made an encoder that counts as pin 10 triggers. Now let's say I wanted to write some g code that tells the hydraulic valve to flip on until the encoder reaches 60 counts. How does my hal program intercept that command?
[04:34:20] <adoyle88> I'm setting up the bend axis as y and x as my feed.
[04:36:43] <adoyle88> so, as an example, I'm going to feed x 10 inches and then feed y 90 (degrees in my case). the y 90 command needs to turn on an output pin to trigger the hydraulic valve solenoid. as the rig bends, the encoder will count
[04:37:15] <adoyle88> then the output pin needs to be turned off when the encoder reaches 90

[08:03:10] <MacGalempsy> anyone around?
[08:03:52] <archivist> no none at all
[08:04:24] <MacGalempsy> ok :]
[08:05:20] <archivist> first rule of IRC ask the real question
[08:06:04] <MacGalempsy> I can see the x-fault as true in the hal pins, but the LED in the pyvcp will not change to red
[08:06:52] <MacGalempsy> I followed the example in the pyvcp section, but there seems to be a problem and I cannot figure out what it is
[08:07:09] <MacGalempsy> any ideas as to why the led wont change?
[08:09:14] <archivist> trace the signal along its path, where does it disappear
[08:10:20] <MacGalempsy> www.pastebin.com/i3ALcPaP
[08:10:35] <MacGalempsy> that is a link to the XML file.
[08:10:49] <archivist> that is not what I said :)
[08:11:22] <MacGalempsy> it disappears between axis and pyvcp
[08:11:34] <MacGalempsy> axis registers the fault with an error msg
[08:11:56] -!- Deejay [Deejay!~Deejay@unaffiliated/dj9dj] has joined #linuxcnc
[08:12:39] <archivist> is it connected to both
[08:13:01] <Deejay> moin
[08:13:40] <MacGalempsy> hello deejay
[08:14:05] <Deejay> \o/
[08:14:14] <MacGalempsy> :]
[08:15:00] <MacGalempsy> it is connected to axis, but obviously not pyvcp.
[08:16:07] <MacGalempsy> in the HAL file, how would I connect it to the pyvcp, I thought by declaring it with a net xfault <= 5i25... would make it visable to pyvcp
[08:17:27] <archivist> if that works for other pins yes, but, you said axis is showing an error, does the led change after you cancel the message
[08:18:09] <archivist> X gets done before y sees it type problem
[08:18:11] <MacGalempsy> no
[08:18:36] <MacGalempsy> ok...
[08:19:29] <MacGalempsy> the error is the standard msg that says the amp faulted (little rectangle at the bottom right corner) similar to the joint error when it hits an endstop
[08:30:38] <archivist> did you click the red x to get rid of the warning
[08:33:44] <MacGalempsy> yes
[08:33:55] <archivist> I still do not know if you overcame the pin voltage incompatibility
[08:34:29] <MacGalempsy> so, when the amp faults, it goes to 19.6 v. when it is clear, it is <2v
[08:35:13] <MacGalempsy> checking the HALPINS for the x and y amp, when the y is clear, the HALPIN shows false, when the x amp is faulted, it shows true
[08:37:29] <archivist> looking up you seem to have a name mismatch
[08:37:32] <MacGalempsy> going to add the links to the postgui_HALFILE and see what happens
[08:38:07] <archivist> x-fault not equal to xfault
[08:38:53] <MacGalempsy> i took the - out and made sure both match
[08:39:25] <archivist> and restarted?

[08:46:47] <MacGalempsy> wow. what a mission...
[08:47:25] <archivist> how many hours to find your own mistake, it is something we all do :)
[08:48:09] <MacGalempsy> your patience is much appreciated.
[08:48:26] <archivist> at the end the ah right moment, knocks it into the back of the brain ready for next time
[08:49:15] <MacGalempsy> it reminds me of this groundwater modeling class in grad school. the only way to find out you had a problem was to run the model, which took a few hours
[08:49:46] <MacGalempsy> I sat there for 2 days solid on 3 machines and was asked several times to stop yelling profanities
[08:50:04] <archivist> overly sensitive maths or badly written models, or rounding errors
[08:50:35] <archivist> we had fur developing a filter simulation for pink noise
[08:50:40] <archivist> fun
[08:51:03] <MacGalempsy> pink noise?
[08:51:23] <archivist> filtered white noise
[08:51:53] <archivist> http://en.wikipedia.org/wiki/Pink_noise
[08:53:37] <MacGalempsy> looks complex...
[08:53:38] <archivist> I wrote a pascal program, boss did the maths, between us we could prove standard parts(reasonable tolerance) could work and be in spec
[08:53:54] <MacGalempsy> was this a part for linuxcnc?
[08:54:17] <archivist> no, day job 20 years or more ago
[08:54:46] <MacGalempsy> ah. pascal. the first programming class I failed was intro to pascal...
[08:55:11] <MacGalempsy> in that wiki link, I like the sound bar that plays the pink noise sound
[08:55:48] <archivist> it was for calibrating microphone amplifiers
[08:56:27] <archivist> we had white,pink and two frequencies of sine
[08:57:41] <archivist> all from digital sources for stability
[08:59:06] <MacGalempsy> so you were making amps and needed a way to test the calibration, or was it a consigned job?

[12:05:09] <sector_0> does anyone know why CNC machine tend to use the parallel port instead of the serial port?
[12:05:54] <SpeedEvil> The serial port on the PC has 3 outputs or so, and 3 inputs.
[12:06:06] <SpeedEvil> And these are awkward to drive.
[12:06:17] <SpeedEvil> The parallel port has at least 8 outputs, and 4 inputs
[12:06:25] <SpeedEvil> 12 outputs
[12:06:39] <sector_0> SpeedEvil, haha, you again
[12:06:46] <SpeedEvil> In modern ports, these may be more flexible as to which is output and which is input
[12:07:37] <sector_0> but ok I get that it has more IO pins, but then why do you need a lot of IO pins just to send G-code down the line?
[12:08:19] amnesic is now known as amnesic_away
[12:08:30] <SpeedEvil> You don't, if that's what you're doing.
[12:08:51] <SpeedEvil> But linuxcnc, and several other programs, directly control steppers or servos or ... in hard-realtime
[12:09:04] <SpeedEvil> This can be lots more flexible than just sending g-code
[12:09:32] <archivist> sector_0, the gcode interpreter in IN linuxcnc
[12:09:38] <archivist> is in
[12:11:07] <archivist> motor control is sent out any ports and switches, encoders are read, all in real time, rs232 serial is too slow
[12:11:09] <sector_0> ohhh
[12:11:11] <sector_0> interesting
[12:11:28] <sector_0> I didn't realize that's the case
[12:12:00] <sector_0> is this the way most CNCs are built?

[12:54:10] <Topy44> hi
[12:54:34] <Topy44> is there a hal pin that signals that a manual jog is currently happening?
[12:55:16] <Topy44> because of $reasons i need the motor enable override pin to be active during manual moves (the one normally used during homing so that the machine can move away from the home switches)
[12:57:54] <archivist> I think homing is clever enough to move off the switches
[12:58:10] <archivist> if you chose the right mode
[12:59:15] <archivist> probably this http://linuxcnc.org/docs/html/config/ini_homing.html#_home_is_shared
[12:59:28] -!- syyl_ has quit [Ping timeout: 256 seconds]
[13:01:12] <Topy44> archivist: my problem isn't homing, that works fine
[13:01:22] <Topy44> i need a pin telling me if it is currently doing a manual move
[13:02:17] -!- f1oat3 has quit [Ping timeout: 246 seconds]
[13:06:57] <jthornton> if after homing your sitting on the home switch you need to change your home position
[13:07:10] <Topy44> again: the issue isn't with homing
[13:07:13] <Topy44> homing works fine
[13:07:43] <Topy44> i need a hal pin telling me that a manual jog is happening
[13:08:33] <jthornton> what are you trying to do?
[13:08:56] <archivist> your first question implies it is a homing switch problem
[13:09:01] <Topy44> its not
[13:09:22] <archivist> (the one normally used during homing so that the machine can move away from the home switches)
[13:09:37] <archivist> what else can we think, tell us more
[13:09:46] <Topy44> so, i built some hardware which, among other things, prevents moves unless everything is in order. this includes going sure that the cooling system is running.
[13:10:08] <Topy44> the cooling system is being turned on by the circuit i built whenever a job is running
[13:10:31] <Topy44> the problem is that i forgot that this means that i cannot do manual moves unless the cooling system is running
[13:11:03] <archivist> see http://linuxcnc.org/docs/html/man/man9/motion.9.html and the axis.N.jog-enable IN BIT
[13:11:19] <archivist> see what it is connected to
[13:11:40] <Topy44> thats an input
[13:11:54] <archivist> see second sentence
[13:12:02] <archivist> follow the net
[13:12:17] <Topy44> you mean inside axis?
[13:12:29] <archivist> inside your hal
[13:12:29] <jthornton> in your hal file
[13:13:21] <jthornton> might be good to know how your blocking motion when the cooling system is not running
[13:13:53] <Topy44> direcrete logic that checks if a line is high
[13:14:03] <Topy44> (the coolant pump has a logic output)
[13:14:42] <jthornton> I mean inside of LinuxCNC how are you blocking motion
[13:14:59] <Topy44> sorry, i don't understand the question
[13:15:24] <jthornton> is the logic output going back to Linuxcnc or is it going directly to your drive?
[13:15:43] <Topy44> it directly controls the enable input of the stepper drivers
[13:15:56] <Topy44> its quite a large circuit
[13:16:01] <Topy44> thats just one of the things it checks
[13:16:06] <archivist> many do this logic in linuxcnc not externally eg classicladder
[13:16:51] <Topy44> yes - but i don't :)
[13:17:53] <jthornton> so you could press the jog button and LinuxCNC thinks the machine is moving when it is not?
[13:18:04] <Topy44> yes
[13:20:12] <jthornton> you might look at connecting the coolant pump output to motion.enable and have a bypass button to jog with
[13:21:01] <jthornton> how are you homing with the coolant pump off?
[13:22:10] <Topy44> homing enables the motor override (so that it can move away from the limit switches)
[13:22:17] <Topy44> which also overrides the coolant pump check
[13:23:07] <Topy44> i cannot really think of an elegant workaround for all of this...
[13:23:36] <Topy44> if i use the override for manual moves it means it could run into limit switches (linuxcnc will still notice, but the hardware check is disabled)
[13:24:00] <Topy44> if i don't check the pump status the laser could go on without the pump being on (its a laser cutter btw)
[13:24:59] <Topy44> one semi-elegant workaround would be to add a signal that tells my circuit that the pump is on when its doing a manual jog, even if the pump is off
[13:25:28] <Topy44> but for that i need a hal pin telling me that its moving
[13:27:54] <archivist> a comparator checking motion=0 or not, moving
[13:30:33] <archivist> I am thinking of motion.current-vel pin
[13:31:27] <archivist> I also think motion.in-position will indicate moving or not
[13:32:16] <archivist> specially as that last pin is true/false TRUE if the machine is in position (ie, not currently moving towards the commanded position).
[13:35:01] <JT-Shop> are you using the spindle to fire your laser?
[13:40:47] <Topy44> archivist: hm, actually the current-vel pin might be an idea
[13:41:14] <Topy44> if motion.current-vel is not 0 but no job is running it must be doing a manual move
[13:42:01] <Topy44> motion.in-position seems to essentially be a bool version of that, yeah, gotta check it on the halmeter

[18:00:43] <SpeedEvil> yeah
[18:01:22] <archivist> I was at a local steel supplier, and they changed blade for just a few cuts for me
[18:03:09] <archivist> a local yocal at a farm gets through loads of blades, seems careless
[18:04:24] <archivist> just last year I replaced the first blade on my lidl special, it did not like me cutting aluminium :)

[18:09:43] <SpeedEvil> and probably a roller infeed and outfeed
[18:10:15] <archivist> band blades go off line when they wear

[18:11:56] <archivist> but is one side going to show

[20:32:17] <pcw_home> The firmware file needs to be in your current directory (and you only do this if you need to change your firmware)
[20:34:58] <pcw_home> So first fetch the appropriate firmware and then:
[20:34:59] <pcw_home> sudo mesaflash --device 5i25 --write 5i25_something.bit
[20:35:01] <pcw_home> ( assuming 5i25_something.bit is in your current directory)
[20:36:12] <pcw_home> then either power cycle or if the _old_ firmware is new enough you can:
[20:36:13] <pcw_home> sudo mesaflash --device 5i25 --reload

[20:37:13] <Nick001-shop> I have it on a stick - whats the current directory - dumb -I know - I'm used to windows and linux is still somewhat a mystery to me but I manage with pointers
[20:37:44] <Nick001-shop> What is a power cycle - a reboot?
[20:38:24] <pcw_home> no power off and power up again, reboot wont do
[20:38:47] <Nick001-shop> I did the reload and it said ok - but when is= did verify it said couldn't find file
[20:39:20] <pcw_home> ok so you can reload so you dont need to power cycle
[20:39:37] <pcw_home> but you still need the new bitfile
[20:40:28] <Nick001-shop> I have the 5i25 software package - exactly where do I copy it to?
[20:40:28] <pcw_home> if "ls" shows you the desired bitfile, its in your current directory
[20:41:11] <pcw_home> anywhere you like. for this purpose, ~/bitfiles is probably ok
[20:41:26] <pcw_home> or do it from the USB stick

[21:09:25] <pcw_home> I guess first question is why are you changing the firmware?
[21:11:52] <Nick001-shop> I've hooked up a stepper and nothing is happening. It's connected to a gecko driver that's been working. I assume I have to load firmware into new cards.
[21:12:40] <pcw_home> If you bought the card with a 7I76, it should have 7i76 firmware already

[21:34:48] <Nick001-shop> Any ideas on why the motor isn't moving? Question - I have step and dir - pins but gecko doesn't use them - do I connect them to gnd or leave them unconnected?

[21:42:14] <pcw_home> I think that you should probably use the STEP- and DIR- pins (instead of the + pins)

[22:46:08] <sector_0> SpeedEvil, another thing about using the parallel port to connect a CNC..what if my PC doesn't have a parallel port?
[22:46:23] <sector_0> many computer manufacturers are phasing them out
[22:46:28] <SpeedEvil> Then you get a pcie PP
[22:46:34] <sector_0> what you use, a FTDI?
[22:46:39] <SpeedEvil> USB sucks
[22:46:41] <sector_0> oh ok
[22:46:47] <SpeedEvil> (from a latency POV)
[22:46:54] <SpeedEvil> many new motherboards have parallel ports
[22:47:04] <SpeedEvil> though few these days have them on the backplate
[22:47:40] <sector_0> SpeedEvil, but I don't understand your comment about USB "sucking" though
[22:47:59] <SpeedEvil> It has lousy latency
[22:47:59] <sector_0> USB2.0 has a throughput of ~12MB/s
[22:48:08] <SpeedEvil> At the very best 1ms
[22:48:32] <SpeedEvil> Typical latencies for many motherboards with PP are 10us.
[22:49:20] <sector_0> SpeedEvil, oh so you're talking about from the time you make the send command, to the time the USB starts sending?
[22:49:29] <SpeedEvil> If you're talking a 800 steps/rev stepper, going at 4000RPM, it matters
[22:49:51] <SpeedEvil> yes
[22:49:52] <Nick001-shop> <pcw_home> Got A axis to move finally. Screwed up where I was plugging in. The - pins only allow the motor to bump a few steps. I'm using a 251X driver and I don't see a common 5v pin. This has a 10 pulse per step deal.
[22:50:20] <pcw_home> Does it have a common ground for step/dir?
[22:50:55] <sector_0> SpeedEvil, I see
[22:51:01] <sector_0> didn't realize that was that case
[22:51:06] <sector_0> hmm
[22:52:03] <pcw_home> if the drives have a common ground you should use the +step pins (sorry if I'm generating useless work)
[22:52:14] <sector_0> that's why you suggested a pcie PP and not a USB-PP
[22:52:18] <Nick001-shop> just a gnd pin then step, dir
[22:52:24] <sector_0> hmm
