[00:00:04] -!- quiqua has quit [Client Quit]
[00:00:26] <andypugh> Well, I do actually have the standalone Fusion app too
[00:00:54] -!- almostworking has quit [Ping timeout: 250 seconds]
[00:01:22] <PCW> ssi: Its in the embedded CPU code
[00:01:24] <PCW> 'reset'; ParmLoc : 0;

[00:01:33] <PCW> 'setlbptimeout'; ParmLoc : 5;
[00:01:34] <PCW> etc etc
[00:01:52] <ssi> the embedded cpu running in the hm2 firmware on the 5i25?
[00:02:00] <PCW> yes
[00:02:38] <ssi> I don't know how I'd begin to get at that
[00:02:51] <ssi> where I'm at right now is with a scope on the rs422 lines just trying to see if I can catch the discovery happening
[00:02:55] <ssi> which so far I'm not
[00:03:06] <PCW> The state register is readable by the host
[00:03:14] <ssi> I have debugs turned on in hostmot2, and I can see it reporting the 7i77 field io remote, but I don't see anything about my other remote
[00:04:23] <PCW> the diiscovery is all documented in the 7ixx manuals
[00:04:25] <ssi> oh wait i got something on the scope that time
[00:04:37] <ssi> I set the config string to 0x00000000 to turn on all ports
[00:04:58] -!- Camaban has quit [Quit: Leaving]
[00:05:24] <ssi> PCW: yea I know it is, but I'm trying to verify baser stuff now, like do I have the phases correct on the wiring, etc
[00:05:56] <ssi> someone else wrote the beginnings of the sserial remote code, and I'm trying to get far enough up to speed that I can begin to help finish it
[00:06:13] <zeeshan|2> ssi you like flexhead tools?
[00:06:20] <ssi> zeeshan|2: not really
[00:06:20] <PCW> the first that sslbp send is a get cookie request (state 3)
[00:06:22] <PCW> so if you are stuck in state 4, sslbp never got a valid response
[00:06:24] <zeeshan|2> i hate em
[00:06:28] <zeeshan|2> ive slipped so much off em
[00:06:34] <zeeshan|2> and hurt myself :/
[00:06:44] <zeeshan|2> now i only pull towards me if using them
[00:06:49] <tiwork> PetefromTn_: well, its in the sealing bath right now
[00:07:12] <tiwork> the black dye I have worked really well... the purple not so much
[00:07:50] <PCW> thats why the state information is valuable
[00:07:52] <PCW> (turning off CRCs and running at 115200 baud also help debugging with standard stuff)
[00:08:40] <tiwork> PetefromTn_: they are both really old, but the purple is water base, the black is solvent based. its slightly splotchy because I tried the purple first, then just dunked it in the black and called it good
[00:14:28] <tiwork> *happy nerd noises*
[00:15:17] <PetefromTn_> sounds good man good luck
[00:15:27] <ssi> PCW: how do I read the state registers from the host?
[00:16:00] <tiwork> its rather ugly
[00:16:08] <tiwork> but I'm blaming the old dye
[00:18:28] <PetefromTn_> I did not have any luck with the solvent dye so far but I have not honestly given it much of a try recently..

[00:21:04] <ssi> PCW: in a 5i25 7i77 config, I'm showing one pair of sserial pins (pin 3 and 4); the field io and remotes on the tb5 header will all work over that same set of pins, correct?
[00:21:15] <ssi> ie, I won't see a second pair of physical pins get assigned to smartserial, will I?
[00:27:11] <Erant> PCW: I'm assuming they're just memory mapped registers, so you should be able to find them in the map and just read them.
[00:27:35] <Erant> Euhm
[00:27:43] <Erant> ssi
[00:31:23] <Erant> Actually, the 5i25 manual makes no mention of the config space layout. Just says it has a single BAR, but no explanation of what is inside of that BAR

[00:38:58] <andypugh> I just tried Fusion360 CAM and it is basically identical to Inventor HSM Pro, so that’s good. It’s a bit more of a peformance getting the model into the app, rather than it just being there.
[00:42:53] <_methods> yeah its quite powerful for the price tag
[00:43:27] -!- Roguish has quit [Quit: ChatZilla 0.9.92 [Firefox 41.0.2/20151014143721]]
[00:44:10] <Erant> _methods: Which is $0 for hobbyist use.
[00:44:15] <andypugh> Having found that the price tag is free for non-profits that’s easy to achieve
[00:44:22] <Erant> Right.
[00:44:32] <micges> Erant: you're talking about PCI config space?
[00:45:18] <Erant> micges: It actually looks like you just talk to it over the mapped memory interface.
[00:45:56] <zeeshan|2> PetefromTn_: howd your flanges turn out
[00:46:09] <micges> if you talking about how to communicate with 5i25, then yes
[00:46:31] <micges> single 64k block
[00:47:07] <PetefromTn_> oh they were okay... the guys seemed to love them so that is nice LOL
[00:47:26] <ssi> that does me no good, as I don't know how to go about reading the 5i25's mapped space while in the middle of a halrun execution
[00:47:43] <zeeshan|2> haha nice
[00:47:56] <zeeshan|2> getting paid musta felt nice too :)
[00:47:56] -!- tiwork has quit [Quit: Page closed]
[00:48:28] <PetefromTn_> yeah they actually paid me all in advance for them but yeah I own the money in the bank now :D
[00:49:06] <PetefromTn_> working on the 3 rotor drawing right now they want a couple of those too
[00:49:42] <micges> ssi: what are you trying to do?
[00:49:58] <ssi> that's a long story
[00:50:00] <zeeshan|2> where is the history tree in fusion 360?
[00:50:06] <ssi> short answer: make a smartserial remote work
[00:50:29] <zeeshan|2> nm
[00:50:29] <zeeshan|2> ;P
[00:50:55] <andypugh> So, the spindle bush for my lathe is meant to be 1.4375” dia and 0.625” taper per foot. So basically nothing standard at all
[00:51:10] <micges> ssi: why does it not working?
[00:51:14] <zeeshan|2> what spindle bushing?
[00:51:22] <ssi> also a long story
[00:51:23] <Tom_itx> andypugh, isn't that the standard for you though?
[00:51:58] <andypugh> ssi: The bush to hold a live centre for between-centres work
[00:52:11] <andypugh> I probably don’t need one, it’s just odd.
[00:52:28] <fenn> 1+7/16 can be cut from 1+1/2 barstock
[00:52:35] <andypugh> (I was thinking of making an adapter to BT30 for machining special tooling for the mill)
[00:52:42] <zeeshan|2> im not ssiu
[00:52:45] <zeeshan|2> how dare you call me ssi
[00:52:59] -!- tinkerer has quit [Remote host closed the connection]
[00:53:15] <andypugh> Ah, oops
[00:53:18] <ssi> lul
[00:53:46] <fenn> no idea what a spindle bush is
[00:54:08] <zeeshan|2> hes talking about the spindle taper
[00:54:10] <ssi> ok got beyond the physical layer issues with sserial :D
[00:54:24] <zeeshan|2> british people call it a bush
[00:54:24] <zeeshan|2> :)
[00:54:32] <ssi> because they're weird :)
[00:54:33] <zeeshan|2> and now i see why my dad calls it a bush too
[00:54:35] <fenn> it's a morse taper adapter?
[00:54:42] <zeeshan|2> cause he learned the queen's english
[00:54:49] <zeeshan|2> usually its mt
[00:54:53] <zeeshan|2> but his is a weird one he's saying
[00:54:54] <andypugh> Well, apart from not being Morse on the outside, yes
[00:54:55] <zeeshan|2> which is interesting
[00:55:23] <zeeshan|2> andypugh: if all youre doing is turning between centers
[00:55:28] <zeeshan|2> wouldnt it be quicker just to make a custom center?
[00:55:31] <zeeshan|2> (dead center)
[00:56:09] <andypugh> I was mainly looking for a nice way to hold BT30 blanks.
[00:56:21] <andypugh> They don’t chuck easily :-)
[00:56:28] <zeeshan|2> whatcha makin
[00:56:49] <andypugh> The last time i tried, super-short ER32 collet holder.
[00:57:08] <fenn> morse taper is 5/8 per foot
[00:57:15] <andypugh> No it isn’t
[00:57:16] <ssi> not all morse tapers
[00:57:24] <ssi> they're all "around" 5/8 per foot
[00:57:44] <andypugh> http://www.tools-n-gizmos.com/specs/Tapers.html#MT
[00:57:44] <fenn> this is one of those situations where it's acceptable to use a time machine to punch someone in the face
[00:59:27] <andypugh> My lathe spindle is close to a stub MT5. But isn't
[00:59:51] <SpeedEvil> fenn: I assume 'Ok, the reference is this one, not any silly number' lead to that
[01:00:22] <fenn> because who needs numbers when you have random pieces of metal locked away somewhere
[01:00:44] <andypugh> Jarno taper are all 0.600” per foot
[01:01:17] <andypugh> (or a nice round 1:20)
[01:02:18] -!- asdfasd has quit [Ping timeout: 260 seconds]
[01:02:44] <fenn> andypugh is it MT 4.5?
[01:03:49] <andypugh> Close, but slightly different taper
[01:04:24] <malcom2073_> Oooo, andypugh that's an awesome chart
[01:04:32] <malcom2073_> I can use that to try and figure out what taper my toolholders have
[01:05:07] <andypugh> (only 1 thou per foot different, it might be close enough, but the lathe manual says 0.625 /ft
[01:05:29] <SpeedEvil> Aren't patents wonderful.

[03:33:54] <veek> while buying a vise what features should i pay attention to: traverse - is 6 cm too little (right now i have to hold an ink-cartridge but i was thinking perhaps a PCB - kind of like a second hand) or should i buy a C-clamp (i'll still need a vise though) - good vises's are xpensiveish
[03:34:51] <ssi> good machine vises will let you put the jaws on the outside of the body, for accomodating big flat pieces like your pcb
[03:37:23] <veek> ssi okayand no point looking for jaw width - jaw opening is what matters right and depth of jaw
[03:37:54] <ssi> depends on your needs really
[03:38:03] <ssi> but wider vises mean bigger vises
[03:38:09] <ssi> mean heavier and costlier vises
[03:38:25] <jdh> and taller, eating your z
[03:38:33] <ssi> nom nom nom

[04:00:39] <renesis> tight enough and they'll want to flex
[04:01:48] <renesis> i did an edge clamp with opan bottom that i would ref to a vise so i could flip and only re-zero x, and could drill without a substrate

[06:28:51] <MrSunshine> hmm bullnose cutters for wood, anyone know of a source for that? =)
[06:29:21] <MrSunshine> with tht evacuum table it could be very usefull for 3d angled faces on sheet =)
[06:30:26] <MrSunshine> and prefereable downcut ;P
[06:30:28] <MrSunshine> haha
[06:34:30] <Connor> Why downcut ?
[06:40:33] <MrSunshine> to push the material against the table to minimize the risk for it comming lose =)
[06:43:34] <toastydeath> a reverse flute bullnose router bit seems like a fairly specialty item
[06:46:57] <MrSunshine> yeah i guess it is :(
[06:47:47] <MrSunshine> with it i could get the 3d profiling capabilities of a ballnose and have a heavy cutter and a small corner radius to get good finnish
[06:48:40] <MrSunshine> but looking at how hard a sheet sits on the vacuum table .. lifting it with a profiling cut like that i guess is nothing to be bothered about :P

[17:01:51] <Erant> Huh. So PathPilot runs on top of LinuxCNC?
[17:02:41] <ssi> pathpilot is a variant of linuxcnc
[17:02:55] <archivist> something like that, also uses a bit of machinekit (also a fork of linuxcnc)
[17:03:42] <Connor> PP is LinuxCNC with a different GUI vs Axis or gmoccapy
[17:03:56] <Erant> Ah. So closed source then.
[17:04:01] <ssi> not exactly

[17:18:03] <Erant> Hmm. So my mill is the tiniest thing (because it has to live in a shop the size of a minivan) and it has a 250W brushless DC motor. According to LittleMachineShop, there's no gearing between it and the spindle. From what it looks like it's just a standard Nema34 servo.
[17:18:19] <Erant> What parts would I be stressing if I replaced it with a 500W servo?
[17:21:49] <Tom_itx> probably the whole thing if it was designed for 250w
[17:22:46] <Tom_itx> you would be tempted to cut more than the rest of it could handle then

[18:17:19] <WZL> hello all,
[18:17:22] -!- lostandfound [lostandfound!~starz@91.216.240.102] has parted #linuxcnc
[18:18:16] <WZL> do you have any recommendation for a touchscreen??
[18:19:05] <Loetmichel> Erant: i have a CNC6040 ... with the 800W VFD spindle
[18:19:39] <cradek> get a usb-connected ELO, and google the model number and see if it works plug-and-play with linux before you buy it
[18:19:45] <Loetmichel> ... that starts flexing in the gantry as soon as you go above maybe 200W input to the spindle from cutting aluminium alone...
[18:19:56] <Loetmichel> so no need to get a bigger motor at all ;)
[18:20:32] <Loetmichel> WZL: i am building 12" tft boxes at the company atm with 12" resistive touchsreens
[18:21:00] <Loetmichel> these would be optimal for a CNC machine i thing. beacuse you can operate them with gloves
[18:21:14] <Loetmichel> but they scratch easily because they are plastic at the front
[18:21:22] <Loetmichel> so its your choice
[18:21:39] <Loetmichel> i can get the specs from the company tomorrow if you whish.
[18:21:44] -!- aventtini6 [aventtini6!~sad@5-12-129-90.residential.rdsnet.ro] has joined #linuxcnc
[18:21:54] <WZL> there is any problem with dirt and coolant with the touchscreens? I have a vw car with a resistive and works ok but i think that a single chip can scratch it
[18:22:54] <cradek> there are a lot of different touchscreen technologies
[18:23:23] <cradek> glass is good for scratch resistance
[18:23:41] <cradek> some will respond to a coolant fingerprint (wet spot) and others won't
[18:23:42] <WZL> loetmichel: I´m from Argentina, locally i can find elo (i think that is capacitive technology) and a saw technology from a chinese brand
[18:24:04] <cradek> ELO has lots of different technologies
[18:24:36] <cradek> I think my mill has an ELO SAW model
[18:25:44] -!- LikeVinyl [LikeVinyl!~pelado@unaffiliated/likevinyl] has joined #linuxcnc
[18:25:48] <WZL> what is the consensus? It worth spend in a touchscreen or I'm better with a panel keyboard and touchpad
[18:25:55] <WZL> is about the same price
[18:26:06] <cradek> it depends
[18:26:12] <malcom2073_> I don't see that much use to a touchscreen unless you're gonna write/use a touch friendly UI
[18:26:14] <aventtini6> hi zee is on guys?
[18:26:15] <malcom2073_> of which, Axis is definently not
[18:26:15] <cradek> I love using Touchy on my mill (it has no mouse or keyboard)
[18:26:29] <aventtini6> what model is his mikron?
[18:26:42] <cradek> AXIS is unusable without a keyboard
[18:26:43] <ssi> I've always wanted to get to where I could use touchy or something similar
[18:26:47] <ssi> I hate having to use a mouse on a cnc machine
[18:26:56] <malcom2073_> I want to use just the keyboard, no mouse or touch heh
[18:27:04] <cradek> AXIS is quite good for keyboard only
[18:27:11] <malcom2073_> I've not yet learned enough of the shortcuts heh
[18:27:12] <ssi> honestly touch-screen plus a nice button panel is what I'd like to have
[18:27:13] <JT-Shop> I use Touchy on my mill and it has a mouse and keyboard... ain't figured out how to enter my password to update without a keyboard
[18:27:17] * Loetmichel simply uses a silicone rubber keyboard
[18:27:24] <cradek> touchy is quite good for touchscreen only
[18:27:32] <malcom2073_> Loetmichel: That's what I have on mine, very nice for oil/chip resistance
[18:27:44] <ssi> I've used the silicone ones, but they're miserable to actually type on
[18:27:46] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[18:27:53] <cradek> JT-Shop: I just ssh from another machine if I need to do that kind of thing
[18:27:55] <malcom2073_> Mine is a silicon cover over a normal keyboard
[18:27:58] <Loetmichel> it even resists red hot chips
[18:28:57] <bz> how bad of an idea is it to use an end mill on sheet metal?
[18:29:17] <ssi> bz: it's fine as long as the sheet metal is very securely clamped
[18:29:20] <ssi> which can be tough to do
[18:29:24] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14040&g2_imageViewsIndex=1 <- better pic
[18:29:38] <JT-Shop> I need to learn how to ssh

[18:29:54] <Loetmichel> bz: if you use double sided tape or a vacuum table: i do it all the time
[18:29:55] <WZL> last week I tested gmoccapy with my surface tablet and looking very good but in the workshop may be a different story.
[18:30:07] <Loetmichel> i wouldnt do it on only "side clapmed" sheets tho
[18:30:47] <Loetmichel> i dont use sssh
[18:31:05] <Loetmichel> but i sometimes use VNC and VLC for the machines Camera
[18:31:05] <WZL> something like this http://www.ruggedized-keyboard.com/photo/ruggedized-keyboard/editor/20150204153333_23050.jpg ???

[18:32:55] <JT-Shop> $0
[18:32:56] <WZL> malcom2073: it says IP68
[18:33:04] <malcom2073_> What'd you aquire? :P
[18:33:24] <JT-Shop> optical comparator
[18:33:25] <malcom2073_> WZL: I'm not familiar with that spec, if it covers what you want to do ,then it'd be fine yeah?
[18:33:29] <JT-Shop> but the light don't work
[18:33:34] <malcom2073_> Those are some serious linear rails on that thing
[18:33:56] <JT-Shop> might make something else out of it and toss the upper
[18:34:01] <malcom2073_> Yeah
[18:35:39] <JT-Shop> has a nice 20" x 20" table
[18:37:37] <JT-Shop> has a nice DRO and scales too
[18:39:22] <bz> ssi, Loetmichel: i'm actually more concerned about the tool tip
[18:39:40] <Loetmichel> bz: why?
[18:39:44] <bz> should i cut at a lower rpm and feedrate?
[18:39:57] <Loetmichel> what kind of tip is it?
[18:40:04] <ssi> the only thing that makes cutting sheet metal different than cutting barstock is the rigidity of the workpiece
[18:40:08] <Loetmichel> "cutting over middle" or not?
[18:40:16] <ssi> so, with adequate clamping, just use the regular numbers for the material
[18:40:23] <bz> ssi: that makes sense
[18:40:33] <ssi> I'm guessing what you really mean is you're concerned about slotting operations
[18:40:42] <ssi> just choose an endmill that's designed to slot cut well
[18:40:44] <Loetmichel> thats what i meant with "tape or vaccum underneath"
[18:40:58] <Loetmichel> thin sheet metal tends to lift of the work table otherwise
[18:41:04] <bz> well i have it screwed onto a sacrifical block of wood
[18:41:05] <Loetmichel> if only clamped at the outside
[18:41:18] <bz> and then the whole thing gripped inside a vise
[18:41:31] <ssi> I'd back up your screws with some double sided tape, unless your screws are pretty frequent and close together
[18:41:39] <ssi> the metal is going to chatter and flex like crazy otherwise
[18:42:24] <archivist> double sided tape is a bugger to get off and helps bend very thin sheet
[18:42:55] <ssi> CA glue on an aluminum block works too
[18:42:58] <ssi> break the CA bond with heat
[18:43:00] <archivist> be prepared to flatten (roll it)
[18:45:06] <Loetmichel> ssi: no heat neceessary
[18:45:21] <Loetmichel> just tap the finsied pice with a rubber hammer from the side
[18:45:29] <Loetmichel> CA glue is brittle
[18:46:12] <Loetmichel> ssi: CA glue works surprisingly well
[18:46:17] <Loetmichel> even on bigger parts
[18:46:19] <FAalbers> Does linuxcnc work with the UC100 ?
[18:46:20] <ssi> yeah
[18:46:26] <Loetmichel> s/bigger/thicker
[18:46:40] <ssi> and the more surface area glued, the better
[18:47:02] <archivist> FAalbers, no it wont
[18:47:08] <FAalbers> OK
[18:47:36] <archivist> USB is a fail for realtime work

[18:51:24] <Loetmichel> one of these
[18:51:48] <Jymmm> Loetmichel: Ah, and VLC?
[18:51:52] <FAalbers> archivist, I was also thinking just using Mach3 on Windows
[18:52:06] <Loetmichel> and yes, on the LlinuxCNC box vlc as a server to do a htp strean and on the win box in the office as a client
[18:52:16] <FAalbers> archivist, And I only need 3 axis
[18:52:17] <Jymmm> Loetmichel: lol
[18:52:47] <FAalbers> archivist, Linuxcnc was just one of the possible systems
[18:53:10] <Loetmichel> and it works surpsisingly well
[18:53:16] <ReadError> mach3 gave my cat feline AIDS ;(
[18:53:17] <Jymmm> Loetmichel: has light?
[18:53:28] <archivist> FAalbers, you are in the wrong place for mach support as it cannot do many things that linuxcnc can on a mill
[18:53:28] <Loetmichel> the linuxCNC box is just a sempron 3000
[18:53:48] <Loetmichel> still it can cope with recoding 640*480 video while milling ;)
[18:53:56] <Loetmichel> Jymmm: the cam? yes
[18:54:02] <Loetmichel> 4 or six white leds
[18:54:24] <WZL> we are using mjpg streamer with a logitech c270 wevcam in a mobile robot and works very good
[18:57:05] <Loetmichel> Jymmm: actually you can see the cam in the second part of the video

[19:05:18] <archivist> FAalbers, also upgrades to later version give you more facilities in linuxcnc, not less

[19:35:51] <SpeedEvil> condensation?
[19:36:39] <malcom2073_> yeah, it got damn cold last night, and today is pretty warm and humid
[19:37:02] <SpeedEvil> a few 10W heaters bolted on helps lots
[19:37:13] <malcom2073_> Really?
[19:37:16] <malcom2073_> hmm
[19:37:43] <SpeedEvil> you only need to get it so it's above the dew point.
[19:37:51] <Jymmm> malcom2073_: is this a garden shed or what?
[19:37:53] <malcom2073_> Or rather, keep it above the dew point

[19:38:04] <Jymmm> malcom2073_: 40W lightbolb?
[19:38:27] <malcom2073_> So it got down to just below freezing last night, and it's probably 70 and 90% humidity right now
[19:38:39] <SpeedEvil> http://www.ebay.co.uk/itm/Screw-Tabs-5-330-Ohm-10W-Aluminum-Wire-Wound-Resistor-/291252622092?hash=item43d002530c:g:uYsAAOSwI-BWF3nm I meant
[19:38:50] <Jymmm> malcom2073_: Thats what we used for a hen house, a red 40W lightbulb
[19:39:41] <malcom2073_> I can't keep the air warm, it takes about 3-4kw to get a 10C temperature rise
[19:40:02] <malcom2073_> Would a 10W heater bolted to the metal base raise the temp of it appreciably?
[19:40:08] <SpeedEvil> ~10 or so of those, bolted over the various components, running at 3-4W each
[19:40:43] <CaptHindsight> and put a cover over it as well
[19:41:03] <malcom2073_> This is really only going to be a problem for a few months in fall, and a few in spring
[19:41:13] <malcom2073_> But yeah, if the heaters would help....
[19:41:15] <Jymmm> malcom2073_: tarp and 40W lightulb
[19:41:16] <CaptHindsight> electric blanket
[19:41:18] <malcom2073_> Wonder how much that would cost
[19:41:26] <malcom2073_> calculator time!
[19:41:58] <Jymmm> If you have a heavy tarp/blankets to insulate it, would take very little heat at all
[19:42:02] <malcom2073_> $10 a month or so, assuming 100W total energy usage.
[19:42:15] <malcom2073_> And constantly on
[19:42:26] <SpeedEvil> and yes
[19:42:32] <SpeedEvil> electric blanket is awesome
[19:42:53] <CaptHindsight> can you flood the garage with nitrogen?
[19:42:56] <SpeedEvil> you can be perfectly comfy in ~0C ambient with ~60W or so of heat and a relatively thin blanket
[19:43:01] <Jymmm> but put LOTS of blankets/insulation over it
[19:43:17] <malcom2073_> That's annoying to have to cover it after every use heh
[19:43:19] <SpeedEvil> CaptHindsight: you probably want fluorine, to provide a reducing atmosphere.
[19:43:37] <malcom2073_> CaptHindsight: if the garage was airtight, this wouldn't be as much of an issue :P
[19:43:47] <CaptHindsight> or argon
[19:43:53] <malcom2073_> I could just control the humidity then directly, ignoring the temp, bring it to 0
[19:43:55] <Jymmm> HYDROGEN!
[19:44:02] <malcom2073_> Worked for zee germans
[19:44:08] <SpeedEvil> There is a major problem with argon.
[19:44:18] <SpeedEvil> You have to make pirate noises every time you go in the shop.
[19:44:28] <malcom2073_> SpeedEvil: You don't already?
[19:46:15] <CaptHindsight> maybe leave the spindle motor running...
[19:46:35] <SpeedEvil> airflow is baaad
[19:46:36] <CaptHindsight> does it generate enough heat to keep the lathe warm?
[19:46:44] <Jymmm> malcom2073_: fill the garage with hay =)
[19:46:45] <malcom2073_> Unloaded? Nah
[19:46:55] <SpeedEvil> Jymmm: and horses
[19:47:06] <Jymmm> Yep, horse poo is steamy =)
[19:47:25] <CaptHindsight> thirsty horses lick the water off the lathe
[19:47:28] <malcom2073_> I have a huge heater I could leave running, but at a dollar an hour.... meh
[19:47:50] <Jymmm> malcom2073_: Seriously, a heavy blanket and a lightbulb is all you need
[19:47:53] <CaptHindsight> and you can eat the horses later
[19:48:03] <Jymmm> CaptHindsight: why later?
[19:48:26] <malcom2073_> the mill isn't a very.... coverable shape, but yeah I can get a really large blanket heh

[19:48:35] <CaptHindsight> Jymmm: he has to solve the rust problem first
[19:48:44] <malcom2073_> CaptHindsight: I don't have rust problems *yet*
[19:48:45] <malcom2073_> :P
[19:48:53] <Jymmm> CaptHindsight: Ah, a spring time feast.... got it!
[19:49:49] <CaptHindsight> the problem with new electric blankets is the stupid safety shutoff after 10 hours

[19:50:25] <Jymmm> malcom2073_: you could even use a 25W bulb
[19:50:28] <SpeedEvil> CaptHindsight: especially not all on ebay
[19:50:32] <CaptHindsight> I guess stupid people were baking themselves
[19:50:39] <CaptHindsight> maybe it's just in the USA
[19:51:02] <Jymmm> I like the 10hr shutoff, especially when you forget to turn it off

[19:51:32] <CaptHindsight> Jymmm: I hotwire mine
[19:51:41] <CaptHindsight> make for good incubators
[19:51:56] <Jymmm> Hey, fleece is REALLY good for holding heat in. I got a 10F degree differencial on a fleece curtain
[19:52:23] <CaptHindsight> last spring I tried to find a heating pad or electric blanket without a safety timer
[19:52:24] <Erant> Rather, air is really good for holding heat in and fleece has a lot of static air
[19:54:22] <SpeedEvil> CaptHindsight: wiring out the timer is trivia
[19:54:23] <SpeedEvil> l
[19:55:15] <CaptHindsight> what else is low cost? Heating pad, fish tank heater...
[19:55:24] <CaptHindsight> engine block heater
[19:55:26] <Jymmm> lightbulb
[19:55:40] <Jymmm> farmers have been using them for decades
[19:55:41] <XXCoder> old overclocked cpu
[19:56:03] <CaptHindsight> Jymmm: but they don't work in the dark
[19:56:06] <Jymmm> pipe the hot water heater exhaust thru the mill =)

[19:58:47] <renesis> i mean if you dont got a bic pen, sure
[19:58:58] <CaptHindsight> Jymmm: I've never seen a lightbulb that works in the dark
[19:59:16] <Jymmm> CaptHindsight: did you lick it?
[19:59:41] <renesis> i wonder if they explode when you do that
[20:00:41] <CaptHindsight> Jymmm: is that the trick? I thought that was only for batteries
[20:00:58] <Jymmm> CaptHindsight: It's for EVERYTHING... just LICK IT!
[20:01:21] <renesis> batteries you have to roll in your hand
[20:01:28] <XXCoder> CaptHindsight: http://www.alibaba.com/product-detail/Screwbase-Ceramic-Infrared-Heating-Elements-With_60136435422.html
[20:01:37] <XXCoder> it generates heat IR with no light
[20:01:53] <XXCoder> im sure theres some in aliexpress too
[20:01:56] <Jymmm> Why? Does the mill need to sleep in the dark?
[20:02:25] <XXCoder> Jymmm: capt apparently has chickens there? he did menion chickens
[20:02:30] <XXCoder> they need to sleep
[20:02:39] <CaptHindsight> how about the walls of a frost free refrigerator? if you cover a lathe will it also keep the dew off of it?
[20:02:45] <Jymmm> XXCoder: That's why you use a red lightbulb
[20:02:53] <SpeedEvil> CaptHindsight: that's not what they do
[20:03:18] <SpeedEvil> CaptHindsight: frost free refrigerators are kept frost free by there being a place cooled to below the temperature of any point in the user cabinet
[20:03:29] <SpeedEvil> which is periodically automatically defrosted
[20:04:00] <CaptHindsight> so can't he just put the lathe in a colder place, like a refrigerator/iceboox?
[20:04:13] <Jymmm> or outside =)
[20:04:50] <Jymmm> just open the garage door, no more condensation =)
[20:04:55] <malcom2073_> Sometimes, I wonder why I even ask questions here :P

[20:05:35] <SpeedEvil> But is often really annoying to do in practice
[20:05:37] <CaptHindsight> Jymmm: then he'll need a gate to keep the horses inside

[20:06:06] <SpeedEvil> malcom2073_: it sort-of-does unless you get external mist
[20:06:25] <SpeedEvil> malcom2073_: airflow reduces dew due to diurnal temperature swings
[20:06:28] <Jymmm> CaptHindsight: Nah, just a chair... http://sadmoment.com/wp-content/uploads/2013/11/Horse-Tied-To-a-Small-Chair-Thinks-It-Cant-Walk-Around.jpg
[20:06:32] <malcom2073_> SpeedEvil: Then why do cars get condensation in the morning?
[20:06:48] <Jymmm> malcom2073_: Yes it does =)
[20:06:50] <malcom2073_> The dew point changes faster than the metal can change temperature
[20:06:52] <SpeedEvil> malcom2073_: that's different. That's due to radiative cooling of the outside skin to space
[20:06:57] <malcom2073_> Hah
[20:07:04] <Jymmm> malcom2073_: deperature differencial
[20:07:10] <Jymmm> temperature*
[20:07:21] <SpeedEvil> The metal is cooled below air temp
[20:07:33] <SpeedEvil> if the metal has a roof over it, then it's cooled only to air temp
[20:07:54] <Jymmm> malcom2073_: horse/moving blanket and a lightbulb, (seriously)
[20:07:55] <SpeedEvil> (but when the day warms up, you can get condensation on cold stuff - which is mitigated by airflow in some cases
[20:08:28] <malcom2073_> Rofl
[20:08:29] <SpeedEvil> malcom2073_: Carefully read the descriptions on ebay electric blankets and find ones without timers
[20:08:47] <malcom2073_> Jymmm: Yeah that's what I may try
[20:09:17] <Jymmm> Put the lightbulb on the ground, heat rises. The blanket(s) keep the heat in
[20:09:45] <malcom2073_> Yeah I need to make some covers for thins on the mill, to prevent the blankets from being one-time use
[20:10:02] <Jymmm> malcom2073_: plastic tarp then blankets?
[20:10:14] <Jymmm> malcom2073_: and cover it no later than 3pm
[20:11:01] <CaptHindsight> I'd couple the lightbulb to the lathe somehow. Heat transfer by conduction will be more efficient than by conduction or radiation. (In this example)
[20:11:32] <Jymmm> It's not gonna matter much really
[20:11:38] <malcom2073_> This is more the mill than the lathe
[20:11:49] <malcom2073_> The mill has way more unpainted surfaces that will rust than the lathe
[20:11:57] <CaptHindsight> Jymmm: but he's in the eastern time zone so do you mean by noon your time?
[20:12:05] <XXCoder> malcom2073_: not under daily use eh
[20:12:33] <malcom2073_> XXCoder: Nope, about once every few days
[20:12:43] <Jymmm> CaptHindsight: "local time"
[20:12:45] <malcom2073_> If it's a bad week at work, much less heh
[20:13:35] <Jymmm> CaptHindsight: I've found you lose "heat of the day" if you go past 3pm

[22:11:54] <gonzo_> any mesa experts on chan this eve, could answer a question please
[22:13:39] <PCW> might be
[22:13:53] <gonzo_> trying to understand how the PC sode of hm2 knows what firmware is loaded on the mesa card. In the case of 7i43 or similar, you do a config=..... but on the 7i90 the firmware is preloaded. So how does the pc side know how to talk to the card?
[22:13:57] <gonzo_> eve peter
[22:14:00] <gonzo_> just the man
[22:14:56] <andypugh> All the firmwares talk the same language, and tell the PC what they have in them.
[22:16:12] <gonzo_> ok, so the board tells the pc what pin/values it has available?
[22:16:18] <andypugh> (and, if they tell the PC that they have a smart-serial module then the PC tells the smart-serial to interrogate all the smart serial ports for connected devices and they report back their capabilities and what they would like their pins to be called.
[22:17:06] <andypugh> The FPGA boards just say how many of encoder/resolver/pwmgen/stepgen etc they have.
[22:17:33] <rene-dev-> PCW: is there a way to change the smartserial timeout?
[22:18:12] <gonzo_> ok, that makes more sense to me now.
[22:18:36] <PCW> which timeout?
[22:18:36] <gonzo_> is there somewhere I can find a list of what the fpga has told the PC what is avail??
[22:18:48] <gonzo_> is that in the dmesg? Or somewhere else?
[22:19:05] <PCW> mesaflash will do it
[22:19:25] <gonzo_> is that working now?
[22:19:57] <PCW> yes:
[22:19:59] <PCW> mesaflash --device 7i90 --addr 0x378 --readhmid
[22:20:07] <PCW> (for example)

[22:25:10] <PCW> how far (in SSLBP states) have you gotten (passed the cookie request/reply etc)
[22:25:28] <rene-dev-> the drive takes a bit longer to answer, as it is busy doinf servo drive stuff: https://www.dropbox.com/s/48ol5vq2awbs9t7/Screenshot%202015-10-28%2023.20.16.png?dl=0
[22:25:35] <rene-dev-> all the way to process data
[22:25:59] <rene-dev-> as far as I can see... how do I read that?
[22:26:09] <PCW> the timeouts are set fairly slow until the process data part starts
[22:26:17] <rene-dev-> BTW, I build a protocol analyzer for sigrok: https://www.dropbox.com/s/hhc4vl7u6vrng0f/Screenshot%202015-10-28%2017.17.07.png?dl=0
[22:26:24] <rene-dev-> how low?
[22:26:43] <PCW> let me check
[22:26:45] <rene-dev-> and where are they set? where do I see the SSLBP state?
[22:27:03] <PCW> its in the CSR
[22:28:00] <rene-dev-> can I set that from hal?
[22:28:30] <andypugh> rene-dev-: Ooh! I take it that the Mac implementation needs a USB-based scope, not GPIB?
[22:28:55] <Sync> andypugh: a saelea clone will do
[22:28:57] <rene-dev-> andypugh its a saleae logic... not a scope
[22:29:07] <Sync> ~saleae
[22:29:07] <andypugh> (My scope is “A Classic” and only has GPIB)
[22:29:16] <PCW> I think there may be a hal pin for it
[22:29:16] <rene-dev-> mine as well, it has a z80...
[22:29:56] <PCW> if not it can be read with raw-read (well and a bit of masking)
[22:29:57] <andypugh> Not sure mine has a CPU at all :-) http://www.komu.jp/336.html
[22:30:19] <Sync> yes it has
[22:30:35] <Sync> I got the one after that one
[22:30:42] <andypugh> I guess it must habe something for the charactger generator
[22:30:51] <PCW> sserial timeout is 400 usec at at startup
[22:32:10] <rene-dev-> servo loop is polling dma rx at 200usec, so that is the maximum delay possible
[22:32:38] <PCW> then its changed to the process data turnaround time + 40 usec (after the first Doit)
[22:34:44] <rene-dev-> that explains the timeouts... how do I change that?
[22:35:01] <rene-dev-> linuxcnc is running at 1khz, I am at 5, so there is plenty of time
[22:35:55] <rene-dev-> im getting loads of (13) Communication error and (3) Timeout and (4) Extra character
[22:36:23] <rene-dev-> but in general it appears to work, when I set fault-inc to 0
[22:37:04] <andypugh> glad you are finding my super-elaborate fault masking system useful :-)
[22:37:30] <rene-dev-> explain to me how it works :D
[22:37:34] <PCW> Its possible to increase these times but would require special firmware
[22:38:10] <rene-dev-> is that in the vhdl or dumbass assembly?
[22:39:17] <rene-dev-> I dont want to use an interrupt...
[22:39:59] <andypugh> rene-dev-: It is described here: http://www.linuxcnc.org/docs/html/man/man9/sserial.9.html
[22:40:27] <PCW> well a faster tic clock that only does comms every tic is a possibility
[22:42:00] <PCW> but requires atomicity guarantees with you 5 KHz tic data
[22:42:29] <PCW> We have 200 KHz tics on some remotes
[22:43:30] <rene-dev-> yes, but you only shift data across, we do a lot of calculations
[22:43:52] <PCW> We do a lot of calcs as well
[22:44:26] <JT-Shop> Tom_itx, actually the drops from the north gable will do the south gable
[22:44:36] <PCW> but typically only the the process data needs the atomicity guarantee
[22:46:03] <rene-dev-> yes, I could go up to 10 khz, but that still does not solve the problem
[22:46:17] <rene-dev-> but 10 khz pid ok for most motors
[22:46:54] <PCW> I think we do this on remotes:
[22:46:56] <PCW> RX --> IRQ --> software FIFO --> polled by foreground task --> software FIFO --> TX
[22:47:20] <rene-dev-> fifo is done in hardware
[22:47:34] <PCW> our foreground task is never interrupted for more than about 20 usec
[22:47:44] <rene-dev-> on the dspic?
[22:48:06] <PCW> we have a little hardware FIFO but not big enough
[22:48:20] <gonzo_> PCW, trying the mesaflash, I'm getting an error that I must select transport layer?
[22:48:41] <PCW> Yes DSPIC the 7I90 sserial remote is all polled
[22:48:55] <rene-dev-> at 200 khz?
[22:49:20] <PCW> Yeah I had forgotten that you need to specify EPP
[22:50:00] <PCW> The 7I90 sserial remote has no other tasks so polling is about 7 MHz or so
[22:50:39] <PCW> (just checking timeouts etc)
[22:52:17] <gonzo_> PCW, ok. better. Does the --readhmid
[22:52:17] <gonzo_> just read the pins from the firmware, without writing to the fpga?
[22:53:00] <PCW> yeah thats all readhmid does

[23:13:53] <rene-dev-> where can I find the assembler for the cpu?
[23:20:34] <ssi> andypugh: I've been working on trying to get sigrok to work with my rigol dso... in theory it should work but I haven't gotten there yet
[23:24:24] <rene-dev-> I guess its not possibel to adjust via csr from hal?
[23:24:43] <PCW> The assemble is TASM ( a table driven assembler) but realy you dont want 200 usec of random comms jitter
[23:24:44] <PCW> How long does the servo interrupt the foreground task? maybe it would be better if the sserial remote was in the foreground
[23:24:50] <PCW> assembler
[23:25:43] <PCW> (rather than polled synchronously with the servo interrupt task)
[23:28:45] <rene-dev-> there is no foreground task, all the stuff is done in one 5khz interrupt, except usb comms, that is done in the main loop
[23:29:08] <rene-dev-> but works with 10khz as well... I try a faster interrupt for sserial
[23:30:42] <PCW> SSLBP assumes remotes have low jitter (<40 usec) and better than about 500 usec worst case response times
[23:31:17] -!- tinkerer has quit [Remote host closed the connection]
[23:31:59] <rene-dev-> its not random jitter, there is no point in having the data early if it is used at 5khz anyway, and only updated at 1
[23:33:00] <rene-dev-> staying below 100 is no problem
[23:34:08] <PCW> if the receive is polled at 5 KHz its will have random 0..200 usec delays relative to the (non synchonous) requests
[23:34:33] -!- AR_ [AR_!~AR@24.238.81.234.res-cmts.sth2.ptd.net] has joined #linuxcnc
[23:35:25] <PCW> (not quite random but some beat frequency because of linuxcnc/ 5KHz clock timebase differences plus linuxcnc jitter)
[23:35:44] <rene-dev-> but we are on hard realtime stuff, always less jitter than the rtapi :D
[23:36:26] <PCW> Yep but not the same timebase (unless you sync your thread to access)
[23:37:24] <rene-dev-> I dont want to sync the mcu to the jitter of linuxcnc...
[23:39:40] <rene-dev-> but similar issue with clk/dir, when you poll it at a fixed rate, you have jitter due to the rational clock ratio
[23:40:01] <PCW> so I would expect a slow variation in delay from baseline to 1/your polling period except when the are
[23:40:03] <PCW> almost in sync and then random full jitter excursions as linuxcncs thread hits a bit early or late
[23:40:45] <PCW> the beat frequency between timebases
[23:42:01] <PCW> I think Jepler has a Python D8 assember but may not admit it
[23:42:38] <rene-dev-> good to know^^
[23:43:54] <andypugh> I assume that flashing a 6i24 with a 5i23 bitfile would fail to be useful?
[23:44:08] <rene-dev-> but the value we are transfering is not affected by the jitter, they are just floats
[23:44:57] <PCW> well it causes some jitter in the position loop
[23:45:57] <PCW> probably not a big issue unless you are after very high precision at high accelerations
[23:46:21] <gonzo_> PCW, have loaded 7i90_epp_svst4_8_ado into the board. I'm playing with one of the demo setups for a simple stepper machine. I'm getting an error from the hm2-stepper.hal, that 'hm2_7i90.0.read' not found
[23:46:44] <PCW> andypugh: mesaflash should not allow you to do that
[23:47:35] <andypugh> OK, so I need to make a 7i44 / 7i85 / 7i49 bitfile for the 6i24 I guess. I doubt that’s a conventional config
[23:48:04] <PCW> gonzo_ did you change the card name in the ini file?
[23:48:44] <PCW> the 5I23 pinout file for it must exist and should work
[23:48:54] <gonzo_> nope, it looked fine. Was already 7i90
[23:49:00] <andypugh> PCW: Dead link on the 6i24 page: The requested URL /software/parallel/6i24.zip was not found on this server.
[23:49:00] <PCW> what size 6I24?
[23:49:19] <PCW> 6i24s use 5i24 firmware
[23:50:52] <andypugh> I think I might have messed up. For some reason I got the 6i24-16. I am sure I intended to get the 25.
[23:51:21] <PCW> should not matter
[23:51:34] <andypugh> RESMOD fits on the 16?
[23:52:55] <andypugh> Ah, look, a 5i24_16_rmsvss6_12_8.bit file exist :-)
[23:55:55] <PCW> Yes a -XC6SLX16 is much bigger that the FPGA on a 5I23
[23:56:26] <andypugh> And I recognise two other configs in the downloaded source that are mine. (PIN_ANDY1_72.vhd sounds like me, as does PIN_HARRISON.vhd)
[23:57:05] <PCW> which do you want?
[23:58:49] <PCW> both have resolvers the Harrison one looks like is has a 7I49/7I39/7I44
[23:59:30] <PCW> sorry andy1 has no resolvers
