[00:00:54] <cradek> andypugh: yeah I found the manual and there's a bunch of uefi/"secure boot" bs that's probably biting you
[00:01:27] <t12> secure boot default disabled
[00:01:30] <furrywolf> why would a cd drive need a battery?
[00:01:43] <t12> lots of usb cant provide enough juice to reliably run a cdrom
[00:02:04] <malcom2073> That's why they use two USB ports
[00:02:07] <furrywolf> hrmm, I've never had a problem.
[00:02:28] <tjtr33> andypugh, ppl are having probs booting that board, this suggests an upgrade to bios than that CSM mode HTH https://wiki.confine-project.eu/testbeds:austria:kvm:bios_gigabyte
[00:02:35] <t12> depends on the machines
[00:02:41] <t12> i commonly had problems on servers
[00:02:53] <cradek> andypugh: if you go through the bios and select legacy wherever you have a uefi option it may all become normal
[00:03:20] <cradek> fucking uefi
[00:04:21] <tjtr33> andypugh, that last url "Please note, that these settings are ment to be used for installing debian using UEFI Grub and kernel."
[00:04:47] <t12> lol @ computers
[00:04:56] <t12> the great rolling failure that is the x86 boot process
[00:08:01] <furrywolf> http://www.samsung.com/au/support/model/SE-208DB/TSBS I have one of those for my portable cd/dvd drive needs... it just has one usb plug, no power cable, and has always worked fine...
[00:08:46] <furrywolf> it even says you can plug it into a tablet and it'll power it.
[00:10:04] <andypugh> So, the solution for a J1800 which won’t beet from USB is to update the BIOS by booting from USB?
[00:10:33] <andypugh> (I have no idea how I typed “beet” for “boot”)
[00:10:39] <furrywolf> hrmm, apparantly there is an optional two-plugged usb cable for use with it. I guess all my systems just have adequate usb ports.
[00:10:54] <furrywolf> because you want to beat the crap out of it. :)
[00:11:51] <tjtr33> andypugh, the first 3 cmds are how they boot form the usb BEFOR they install the upgrade. that maybe of use to you
[00:12:39] <andypugh> I will try again tomorrow, unless something more interesting crops up, like sorting my sock drawer. But for tonight it is 1am and I have had enough.
[00:12:44] <tjtr33> and the whole invocation may be necessary, i dont have the mobo to try
[00:13:08] <tjtr33> gnite ( i agree a sutiable cd may be the way )
[00:13:27] <andypugh> I am going to be very upset if the problem _wasn’t_ with the motherboard.
[00:13:46] <andypugh> (ie, the reason that my mill won’t run for more than 60 seconds)
[00:14:14] <Tom_itx> what started that issue?
[00:14:42] <andypugh> If I knew that, I wouldn’t be swapping parts to figure out the problem.
[00:14:52] <Tom_itx> heh true
[00:15:03] <andypugh> But the problem appears as PCI comms problems with the 5i23.
[00:15:09] <Tom_itx> doing nothing special to the control / system?
[00:15:16] <Tom_itx> hmm
[00:15:20] <andypugh> (And I can buy a new motherboard a lot more easily than I can buy a new 5i23)
[00:16:42] <andypugh> Unfortunately (and unexpectedly) I can’t just plug the old SSD into the new MB. It just doesn’t physically fit.
[00:18:16] <andypugh> (It’s an SATA DOM, and the SATA ports are in a place where the DOM case overlaps the PCI slot)
[00:19:46] <tjtr33> cloudboot.org :) (hey its real!)
[00:21:43] <andypugh> os1r1s: There is a fair bit of XHC stuff archived on the forum.
[00:22:14] <os1r1s> andypugh: I'm sorting through it. I'm trying to figure out if the wired works as well as the wireless.
[00:22:41] <andypugh> Wired ought to work better than wireless.
[00:23:58] <os1r1s> andypugh: Thats what I was thinking, but everything referred to wireless

[00:38:01] <furrywolf> heh, reading the current news on uefi... apparantly microsoft is doing what everyone figured they'd do with windows 8 with windows 10, and making oems make systems that won't boot anything else.
[00:39:08] <furrywolf> want to run linuxcnc? tough shit.
[00:41:58] <CaptHindsight> it's their last chance since Android has taken over much of their consumer business
[00:42:55] <CaptHindsight> the high volume server buyers won't stand for it
[00:43:11] <CaptHindsight> so that leaves business desktops and laptops
[00:43:25] <furrywolf> the consumer hardware manufacturers will quite happily do it.
[00:44:04] <CaptHindsight> yeah, try and change the OS on most tablets and phones

[01:20:50] <Jymmm> XXCoder: I would have said a dremel, but sounded insulting
[01:21:06] <XXCoder> dremel is useful but not magic
[01:21:16] <XXCoder> its not even too serious tool

[01:28:44] <XXCoder> in japan my hands can be used like a nice but this method doesnt work with the tomato
[01:29:01] <Jymmm> =)
[01:29:11] <Jymmm> NOW how much would you pay for it...
[01:29:27] <XXCoder> blah blah but legend lives are the skins it was more clever than a clipper
[01:29:36] <XXCoder> gonna love autocapotion
[01:30:06] <XXCoder> but look use this aging it's a person carving knife
[01:30:07] <furrywolf> after the job it did with that distributor replacement video a while ago, I question its accuracy.
[01:30:08] <XXCoder> NOOOOOOO
[01:30:10] <Jymmm> speach to text?
[01:30:17] <XXCoder> yeah try it out
[01:30:20] <XXCoder> click CC button
[01:30:34] <Jymmm> XXCoder: in the future
[01:31:02] <XXCoder> "it's more than amazing its again sooo cooperate in cannes"
[01:31:57] <Jymmm> I will say this though, it works GREAST for cutting foam and EPS
[01:32:16] <XXCoder> LOL bad one.. "the legend is bad genuine concern with a genuine ginsu price"
[01:33:15] <Jymmm> In Japan... The hand can be used like a knife. But this method doesn't work with a tomato
[01:34:07] <Jymmm> High carbon steel blades (my ass, it's springy SS)
[01:34:36] <XXCoder> yeah I figured that
[01:34:50] <XXCoder> just love how autocaptions mangle it though
[01:35:00] <Jymmm> =)
[01:35:01] <XXCoder> it usually happens with music or loud background
[01:35:10] <XXCoder> in least thats what im thinking
[01:35:23] <Jymmm> no music, only background cutting sounds
[01:35:33] <XXCoder> interesting
[01:35:39] <XXCoder> Jymmm: one odd thing though
[01:35:43] <Jymmm> err sawing sounds =)
[01:35:49] <XXCoder> older goverment videos always has perfect autocaptions.
[01:35:57] <XXCoder> they must speak VERY clearly

[01:42:00] <XXCoder> Jymmm: just wish those videos was ran though video stabilizer
[01:42:05] <XXCoder> recent new tech
[01:42:16] <XXCoder> not camera stabilizer thats older one
[01:44:29] <XXCoder> oh yeah! that 3d cylinder for computing values was done with millenium clock too
[01:44:39] <XXCoder> so it adjusts for timing across long time
[01:44:44] <XXCoder> so no need to adjust

[03:01:55] <XXCoder> not bad
[03:02:03] <XXCoder> but I dont know if that clamp will fit my router

[03:13:30] <Tom_itx> os1r1s, you'd have to ask pcw_home
[03:13:37] <Tom_itx> i would think so
[03:14:42] <XXCoder> is 27000 usable rpm?>
[03:14:52] <XXCoder> wood certainly but alum?
[03:15:15] <os1r1s> Tom_itx: I wasn't sure how each card would be referenced. pcw_home Comments?
[03:15:22] <Tom_itx> XXCoder, it all boils down to chip load

[03:16:01] <XXCoder> if fur
[03:16:25] <XXCoder> also dont forget that if too fast it wears tools

[03:23:29] <Tom_itx> as long as your chip load is right it should
[03:23:45] <Tom_itx> and your machine doesn't shake apart
[03:24:45] <XXCoder> yeah'
[03:25:06] <XXCoder> that $35 motor with $5 volt doubler would work
[03:26:26] <Tom_itx> you better make sure the spindle will handle it
[03:26:36] <XXCoder> no spidle

[03:28:55] <XXCoder> but I dont know if that clamp will fit
[03:29:23] <XXCoder> im bit concerned with that length too, if its too long I can't use tools because it wont clear stock
[03:29:29] <pcw_home> normally one host card is enough though

[03:34:23] <PetefromTn_> we actuallly only shot off half of the mortars. The damn things were shaking the windows in our house so I didn't want to push my luck
[03:36:59] <os1r1s> pcw_home: I have two machines plugged into one computer and prefer not to swap cables around. One drives more than enough for one machine. I'm assuming a db25 switchbox is a bad idea and that a card would be a better one. What are your thoughts?

[03:41:03] <pcw_home> probably workable but not optimum (and probably an untried setup)
[03:41:04] <pcw_home> a switchbox might be OK _if_ the machine grounds are bonded together
[03:41:27] <XXCoder> hey furrywolf
[03:41:56] <pcw_home> (because switchboxes often switch all wires including grounds)
[03:41:57] <os1r1s> pcw_home: Ok. I'll go with one for now. Thank you for responding.

[03:51:43] <XXCoder> I'm wondering if that spindle and clamp would fit my router
[03:54:20] <furrywolf> so, maybe I'm just a redneck, but does anyone else see those videos of russian rural life and think rural russia would be a really cool place to spend a summer?

[04:26:26] <zeeshan> modbus is shit slow
[04:26:26] <zeeshan> lol
[04:26:55] <XXCoder> in general, is 27000 rpm useful?
[04:27:00] <zeeshan> i think its cause its a userspace comp
[04:27:03] <XXCoder> I dont wanna buy and it turns out too fast
[04:27:04] <zeeshan> XXCoder: do the math!
[04:27:24] <AGR> Pcw_home, so insert this line to enable, does the rest look ok
[04:30:10] <XXCoder> zeeshan: can it even cut aluminium?
[04:30:17] <XXCoder> im not sure how to do math
[04:30:26] <XXCoder> I know its fine for wood
[04:32:33] <XXCoder> http://blog.cnccookbook.com/2012/03/27/10-tips-for-cnc-router-aluminum-cutting-success/Feeds%20and%20speeds%20sweet%20spots
[04:33:09] <zeeshan> i told you the other day :{
[04:33:12] <zeeshan> you dont pay attention
[04:33:13] <zeeshan> !
[04:33:25] <XXCoder> mybe I missed it
[04:33:28] <zeeshan> rpm = 4*cuttingspeed / diameter of tool
[04:33:39] <XXCoder> ahh yea]
[04:33:42] <zeeshan> feed rate (in inches per minute) = #of teeth * rpm * chip load
[04:33:49] <zeeshan> chip load for a router should be around .0015
[04:33:54] <zeeshan> you know the rest
[04:34:36] <zeeshan> jeez
[04:34:42] <zeeshan> if you ran a 1/4" cutter, thats 1700 sfm
[04:34:51] <zeeshan> you should be able to get away with carbide
[04:34:59] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[04:35:34] <zeeshan> you could run a 1/8" cutter without problems
[04:35:35] <zeeshan> at that speed
[04:36:17] <XXCoder> math is always easy its figuring what numbers to use thats bit hard atm for me lol
[04:36:30] <XXCoder> I dont know what my machine max sfm is
[04:36:30] <zeeshan> youre gonna need to feed at 81 ipm
[04:36:40] -!- norias has quit [Ping timeout: 246 seconds]
[04:36:46] <XXCoder> nor ipm
[04:36:51] <zeeshan> if you were to run at 27,000 rpm
[04:36:57] <XXCoder> whats average homebew router ipm
[04:37:00] <zeeshan> assuming 2 flute cutter and 0.0015
[04:37:03] <zeeshan> no idea =/
[04:37:22] <XXCoder> it was pretty quick when I tested it but well
[04:38:23] <furrywolf> argh... I'm getting really fucking sick of being unable to do anything. I have to try going to work again tomorrow, but I don't think I'll be able to finish the day.
[04:38:36] <XXCoder> would back brace work>
[04:38:48] <zeeshan> furrywolf: you do deliveries?
[04:38:55] <Jymmm> furrywolf: go smoke some
[04:39:02] <furrywolf> yes
[04:39:04] <furrywolf> XXCoder: no
[04:39:08] <furrywolf> Jymmm: hell no
[04:39:18] <zeeshan> you sir need a new job
[04:39:22] <zeeshan> too smart to be doing deliveries
[04:39:23] <Jymmm> furrywolf: it works for back pain
[04:40:03] <furrywolf> Jymmm: even if I developed enough brain damage to want to, it's grounds for immediate dismissal from my job. even having a 215 card disqualifies you, before you even fail the drug test...
[04:40:32] <XXCoder> dang
[04:40:48] <Jymmm> furrywolf: That would be a medical disqualification?
[04:40:53] <XXCoder> zeeshan: can guess from video? https://www.youtube.com/watch?feature=player_detailpage&v=ltnfI5XqtSo#t=329
[04:41:08] <furrywolf> Jymmm: no, that would be "you're fired, get your stuff and get the fuck out".
[04:41:32] <Jymmm> furrywolf: sounds like a lawsuit to me
[04:41:44] <XXCoder> Jymmm: not at "right to work" states
[04:41:50] <furrywolf> ... complaining you got fired for breaking the law is not grounds for a lawsuit.
[04:41:52] <XXCoder> can fire for snorting snow
[04:41:59] <XXCoder> or snorting literal snow
[04:42:13] <zeeshan> you dont need to guess
[04:42:17] <Jymmm> anyhow...
[04:42:18] <zeeshan> you can see it in his mach 3 velocity profile
[04:42:20] <zeeshan> 116 ipm
[04:42:22] <zeeshan> is max speed
[04:42:28] <zeeshan> but that doesnt mean you can machine at that speed
[04:42:33] <zeeshan> might stall the motors
[04:42:57] <XXCoder> honestly I would run wood most times which is not problem
[04:43:05] <XXCoder> just that sometimes I want mill alum
[04:43:15] <XXCoder> my bosch router can do 8k to 12k
[04:43:31] <XXCoder> which is good range but it cant be clamped :(
[04:43:49] <furrywolf> this new leg problem is even more annoying... if it's not better tomorrow I'll need to go back to the hospital... blargh.
[04:51:57] <XXCoder> sucks
[04:51:57] <furrywolf> zeeshan-lab: a new job would be nice, but work is very hard to find, and I don't have many useful skills.
[04:52:19] <XXCoder> zeeshan: interesting https://www.youtube.com/watch?v=yn-VCtGEmnA
[04:52:27] <XXCoder> it has same design as mine
[04:52:38] <XXCoder> but it has spindle and clamp for it
[04:53:57] <XXCoder> hm closeup shows few differences
[04:55:06] <XXCoder> that one looks exactly same https://www.youtube.com/watch?v=htsXSj8kclI
[04:55:11] <XXCoder> but clearly modified.

[05:19:28] <renesis> haha @ furrywolf not having skills
[05:19:44] <furrywolf> ?
[05:19:56] <XXCoder> ?
[05:20:03] <renesis> while you might suck at kissing ass, entering all the data, and bullshitting people,, you could prob find a job as a tech somewhere
[05:20:31] <furrywolf> I know a little about a lot of things, which isn't generally what employers want.
[05:20:47] <renesis> but yeah, kissing ass, data entry, bullshit the customer, this is where all the jobs at
[05:21:28] <renesis> honestly thats how a lot of techs are, and then you specialize them
[05:21:44] <furrywolf> I know a lot more about non-tech-things than tech things
[05:21:59] <renesis> if you didnt live out in the middle of nowhere it would be easier to find something techy
[05:22:41] <XXCoder> I think she does
[05:22:41] <XXCoder> nowhere that is
[05:22:49] <renesis> but you know more than some of the people ive worked with
[05:23:16] <renesis> xxcoder: its so fuckin beautiful tho
[05:23:41] <XXCoder> I bet. I'm lucky enough to live so near inlet sea pudget sound
[05:23:41] <furrywolf> I can do automotive, electrical, mechanical, plumbing, carpentry, well drilling, computers, programming, teaching, sex toy sales, hydraulics, pneumatics, engines, handyman work, small engine repair,... I'm just not anywhere close to an expert at any of it.
[05:24:12] <Jymmm> furrywolf: just make/sell sex machines/toys/chairs
[05:24:32] <XXCoder> or any combation thereof lol
[05:24:38] <renesis> could do that in LA or the bay
[05:24:39] <furrywolf> Jymmm: I'd need a girlfriend who's into such things to help me test them, and that's much, much harder to find than a good job.
[05:24:44] <renesis> not joking
[05:24:58] <renesis> furrywolf: porn hookers
[05:25:04] <Jymmm> furrywolf: NO, thats playing, not working
[05:25:38] <renesis> you come to chatsworth, you say hey i can build you these things, negotiate somewhat reasonable terms (remember youre just starting out)
[05:25:56] <renesis> and if they have money to get you going, they should be able to provide the girls
[05:26:30] * furrywolf doesn't like porn, hookers, or casual sex.
[05:27:07] <renesis> well then breaking into sex toy r&d might be difficult
[05:27:13] <XXCoder> you dont have to test em with em
[05:27:14] <renesis> and its work
[05:27:20] <renesis> youre not always supposed to like it
[05:27:23] <XXCoder> get 2 women if some toy needs 2
[05:27:37] <renesis> you can get a hazmat suit
[05:27:37] <furrywolf> trust me, you can tell which toys were designed by people who never actually used them. :P
[05:27:40] <renesis> itll be neat
[05:27:43] <furrywolf> (most of the big brands, for example....)
[05:29:02] <renesis> anyway, youre broad skillset is what most good techs have, r&d and service
[05:29:45] <renesis> you usually have to be able to support multiple engineering fields, so cross functionality and learning things quick are huge
[05:31:57] <renesis> my guess is your area has 10x more tech geeks than it needs =(
[05:32:13] * furrywolf isn't a tech geek
[05:32:24] <renesis> youre pretty technical
[05:33:07] <furrywolf> I just upgraded to a 1.8ghz core 2 duo.
[05:33:30] <renesis> i beat you this one is 2.0ghz
[05:33:47] <furrywolf> tech geeks care about computers enough not to use something ten years old.
[05:33:58] <renesis> machinery and fab is technical
[05:34:27] -!- micges has quit [Ping timeout: 255 seconds]
[05:34:43] <renesis> tech geeks build computers decent enough to outlast that generation of gear, making upgrade costly with low roi
[05:35:02] <renesis> and since the computer is well built, it does fine even 6 years later
[05:35:04] <furrywolf> I bought it for $40 on craigslist.
[05:35:10] <renesis> neat
[05:35:20] <XXCoder> ren yeah my old pc lasted years
[05:35:25] <XXCoder> built it I think 2006 or so
[05:35:32] <renesis> i think thats what i paid for my linuxcnc pc
[05:35:35] <XXCoder> and my pc is likely to last as long
[05:35:51] <XXCoder> *new
[05:35:54] <renesis> xxcoder: i upgraded psu and vid cards, went to ssd, because can be pushed into new system
[05:36:11] <renesis> so now i have more gpu ram than system ram because i wont buy more ddr2
[05:36:32] <XXCoder> heh never upgraded mine, other than downgrade of raid 5 - 3 60 gb disks to single 350 gb hd
[05:36:45] <renesis> i bought ddr2 for this laptop, 8gb was like $120 or something crazy
[05:36:57] <XXCoder> crazy
[05:37:10] <XXCoder> new pc 16 gb ram for less
[05:37:17] <renesis> upgrading old parts is so cost dumb
[05:37:41] <renesis> but yeah that + ssd, and this laptop is usable, not enough bottleneck so now the cpu overheats
[05:38:03] <XXCoder> lol
[05:38:13] <furrywolf> best deal on ram I've gotten was around 2001 when I got 2GB (4 512 sticks) of PC133 for $1 at a yard sale.
[05:38:14] <XXCoder> AC cooled laptop ;)
[05:38:48] <XXCoder> lol my steal was $200 for 4 mb ram (4x1mb)
[05:38:48] <renesis> but it has a 15" 1920x1200 monitor, and is a work dell, is almost tankish like old thinkpads
[05:38:59] <XXCoder> that era it would cost $450
[05:39:18] * furrywolf had a $4k 16kb ram upgrade for a trash-80...
[05:39:59] <renesis> anyway, stop faking, move to a place with jobs and work
[05:40:17] <renesis> or dont, i wouldnt, i would stay where you are forever if you can hustle it
[05:40:36] <XXCoder> furrywolf: online sex toys shop
[05:41:00] <furrywolf> XXCoder: very hard to make money doing that.
[05:41:14] <furrywolf> margins are SLIM and competition is plentiful.
[05:41:17] <XXCoder> yeah
[05:41:22] <renesis> pre-established china competition
[05:41:44] <XXCoder> more specialized as long as its not one or 2 customer specializion
[05:42:08] <renesis> then you got a few months before its copied
[05:42:14] <furrywolf> you either have to have an uncommon specialty (anything more than about three people are into is already taken) or enough funding to start very, very big.
[05:42:25] <XXCoder> interesting
[05:42:36] <renesis> and if you start big you gotta be able to change direction quick
[05:42:50] <furrywolf> for example, the other day I cam across a business specializing entirely in silicone colon tubes. if you can think of it, there's a store selling it. :P

[05:43:46] <renesis> manufacturing stuff is hard =(
[05:44:36] <renesis> i think you could do fab work
[05:45:00] <furrywolf> I have no drafting, cad, or cam skills.
[05:45:03] <renesis> i just dont think it would be very consistent
[05:45:27] <furrywolf> or much practical machining experience
[05:45:32] <furrywolf> or tooling
[05:45:32] <furrywolf> or a shop
[05:45:37] <furrywolf> or a machine worth owning
[05:46:02] <renesis> right im saying you could work in a shop that does fab, and you would know enough they could teach you what you dont know
[05:46:43] <furrywolf> not a lot of fab shops left here.
[05:46:53] <renesis> prob most of the work around you would be for artsy types, and thats prob way spotty
[05:47:01] <furrywolf> and they're doing the opposite of hiring.
[05:47:56] <renesis> kind of same in LA/bay, but these lots of places so usually something
[05:48:28] * furrywolf wants to live as far from LA as possible
[05:48:44] <renesis> dunno east coast kinda sucks
[05:49:04] <furrywolf> cities suck in general.
[05:49:13] <renesis> youd prob like the santa monica mountains, these places for you to hide
[05:49:40] <furrywolf> I'm a country wolfy. dirt roads are good.
[05:49:42] <renesis> well cool thing about LA is you drive 15min and its like youre in the middle of nowhere
[05:50:01] <XXCoder> its same for las vega
[05:50:14] <furrywolf> my experience is you drive 15mins, and you're 50 feet from where you started... if traffic actually moving at all that day.
[05:50:14] <XXCoder> BIG city and you can walk to where you can see nothing manmade
[05:50:23] <renesis> bit more geographical diversity in LA
[05:50:33] <renesis> but yeah pretty much same thing
[05:51:01] <Jymmm> Santa Monica HILLS
[05:51:10] <XXCoder> man
[05:51:13] <furrywolf> last time I was in the bay area, it took two fucking hours to get from hayward to the bridge...
[05:51:19] <renesis> why arent they mountains?
[05:51:25] <XXCoder> sellers NEVER state design facts for any clamp for spidle
[05:51:41] <Jymmm> renesis: MtBaldy is a mountain
[05:51:54] <furrywolf> also, it's way too fucking hot down there
[05:51:59] <Jymmm> Big Bear is a Mountain
[05:52:53] <renesis> theres sheer canyona and cliffs everywhere
[05:53:48] <renesis> also the stuff on the east side of the valley by angeles national forest is supposedly some of the steepest inclines in the country
[05:54:12] <furrywolf> bbl, sleep
[05:55:08] <renesis> also fuck ksitting in traffic, i drove mulholland home all last week instead
[05:55:56] <renesis> worst case you get stuck behind someone going the speed limit

[09:58:37] <MrSunshine> aluminium
[09:58:48] <MrSunshine> its a 3 way compressed air cooling system for the router =)
[10:00:42] <XXCoder> oh yeah
[10:00:42] <XXCoder> saw something like thaty
[10:00:48] <XXCoder> its nice way
[10:01:02] <XXCoder> though one at machine I used it was made from bent pipe

[10:03:46] <MrSunshine> hopefully will get it done to the end of this week as im going to cut plastics then =)
[10:04:02] <XXCoder> hopefully my router will be done this year :P

[10:04:07] <MrSunshine> so
[10:04:10] <XXCoder> just ordered that 27000 rpm router
[10:04:11] <MrSunshine> XXCoder: haha =)
[10:04:15] <XXCoder> lets see how well it works
[10:04:42] <XXCoder> I just dont have any machine to build new mount for bigger sized spindle, not even slightly bigger 53mm.

[13:51:54] <Crom> hell 64 char would still be less than 8kilobyte

[14:52:45] <Jymmm> Crom: how not great?
[14:52:48] <Jymmm> 50% ?

[14:54:52] <Crom> take one apart and see if you can extra cooling

[14:58:09] <Jymmm> It's just an audio cable using VOX
[14:58:23] <Jymmm> ghettopeater =)
[14:58:36] <Crom> or open up the radio and get the audio before the (de)emphasis circuit and feed it into the other radio after the (de)emphasis
[14:58:57] <Crom> search winsystem flat audio
[14:59:54] <Jymmm> Crom: nothing really for "flat audio"
[15:00:25] <archivist> my kenwood mobile does have crossband repeater mode built in :)

[15:06:39] <Jymmm> I'll have to add a CWID'er, but not a biggy
[15:06:54] <gonzo__> not many modern dual band radios will do full duplex, as they often have wideband rx facilities

[15:07:19] <Jymmm> The TH-D7a does do FULL duplex

[15:19:49] <PetefromTn_> I think Connor bought one of those wildhorse ones tho.

[15:21:10] <archivist> later delved deeper to the contacts
[15:21:42] <zeeshan> im trying to figure out why the probe a lot of people buy from cnc4pc for likr 135$
[15:21:49] <zeeshan> has a repeatability of 0.0002-0.0005"
[15:21:59] <zeeshan> while the renishaw has 0.00002
[15:22:11] <PetefromTn_> renishaw is a strain gauge or something no?
[15:22:21] <archivist> may I recommend this light reading http://www.collection.archivist.info/archive/mirror/renishaw/Technical%20article:%20OMP400%20-%20strain%20gauge%20probe%20-%20Renishaw%20probing%20technology%20and%20the%20new%20OMP400.pdf
[15:22:27] <PetefromTn_> and the others are the six ball bearing contact style
[15:22:36] <zeeshan> PetefromTn_: nah
[15:22:50] <archivist> shows the contact errors and why the strain gauge is better
[15:23:05] <zeeshan> https://patentimages.storage.googleapis.com/pages/US5146691-2.png
[15:23:07] <PetefromTn_> nah what?
[15:23:08] <zeeshan> i see some ballz
[15:23:19] <archivist> the three point support are a basic error source
[15:23:56] <archivist> that is an older patent
[15:24:01] <zeeshan> O
[15:24:56] <archivist> that doc I found on renishaws sight is interesting
[15:25:02] <archivist> site
[15:25:29] <zeeshan> so basically two important mechanisms
[15:25:36] <zeeshan> one is low friction drive of probe
[15:25:43] <zeeshan> and the fact that it returns back to stock position
[15:25:48] <zeeshan> and then the triggering portion
[15:26:20] <zeeshan> why the 6 dowels?
[15:26:50] <archivist> 6 balls 3 dowels
[15:26:56] <zeeshan> no i see those
[15:26:59] <zeeshan> b ut theres some more dowels
[15:27:52] <archivist> that patent is inverting the function to 3 balls 6 straight
[15:28:04] <archivist> same result
[15:28:37] <archivist> slot edges
[15:29:07] <zeeshan> how much did that probe cost you btw
[15:29:14] <Jymmm> Crom: I could use a pi, but this would allow to control/operate a QRP rig remotely
[15:29:25] <archivist> erm....not a lot....£5
[15:29:54] <zeeshan> mp series is strain gage based?
[15:30:11] <archivist> but mine has a worse contact design then the original renishaw

[15:31:56] <zeeshan> its cheap
[15:31:59] <archivist> has three flats three balls and a flat spring to keep in contact and inline, therefore the asymetric forces are much worse than in that paper
[15:32:01] <Jymmm> Crom: Basically qrp rig with a 7000ft tall antenna =)
[15:32:04] <zeeshan> and 0.0002 to 0.0005 is more than adequate it'd think
[15:32:54] <archivist> check with a ring, I bet they dont achieve the spec they claim
[15:33:16] <MrSunshine> XXCoder: hehe pattern fell apart a bit when i tried to glue it. . trying to save it but else i have to make a new one :P
[15:33:35] <archivist> you should see a triangular error like in that paper
[15:33:36] <zeeshan> i has round gage blocks
[15:34:23] <archivist> I think I have dreamed up a different strain gauge design :)
[15:34:48] <archivist> so should not be under their patent :)
[15:36:09] <archivist> must get bits on the way from hong kong/china
[15:36:27] <zeeshan> i have a different design in mind
[15:36:35] <zeeshan> im not sure why it's not as utilized
[15:36:40] <zeeshan> a combination of proximity switches
[15:36:44] <zeeshan> non contact
[15:38:10] <archivist> one needs same detection in all directions really not just a few
[15:39:09] <zeeshan> you aint getting me :P
[15:39:19] <zeeshan> think of a ball joint on a car
[15:39:36] <zeeshan> but a shaft protruding out

[16:02:34] <archivist> os1r1s, my interest is in the technology and doing it even cheaper
[16:05:28] <os1r1s> archivist: A really cheap way of doing it is just a contact probe.

[17:18:22] <furrywolf> no, normal car insurance only covers other people, not you.
[17:18:37] <monttyle> Even here in Canada, it's very hard to prove that an accident actually caused your bad back or that it's bad enough to need treatment / keep you off of work.
[17:18:39] <furrywolf> her car insurance needs to cover me. they will, of course, try to get out of paying it.
[17:18:40] <archivist> other car hit you charge them
[17:18:42] <os1r1s> archivist: Mine swelled 20-30% because of obamacare. And that is consistent with other large companies.
[17:18:48] <Sairon> hmmm
[17:18:56] <Sairon> aren't you... required to have health insurance now?
[17:19:17] <furrywolf> no. it's still unaffordable for people who work for a living.
[17:19:27] <ssi> but how can that be?
[17:19:39] <Sairon> uh. so the people that have insurance don't work for a living?
[17:19:39] <monttyle> os1r1s: Your lack of health care was already more expensive than most other countries' healthcare by far. There's middlemen of middlemen of middlemen that'll have to be cut out before you can begin to approach parity. The US has taken the first steps, I hope, but has a long way to go.
[17:19:40] <os1r1s> Sairon: You are, but where you get it changes.
[17:19:42] <ssi> the ACA has got "affordable" right in the name!
[17:20:31] <os1r1s> ssi: It extended coverage to people that weren't covered by corporate insurance policies. So more people have insurance. But the insurance companies just raise the premiums so that they can cover the additional people.
[17:21:02] <ssi> perhaps the sarcasm filter isn't sensitive enough in here today
[17:21:09] <os1r1s> :P
[17:21:45] <furrywolf> ssi: read up on "doublespeak". you can ask at the ministry of truth.
[17:22:02] <ssi> fwiw, the US healthcare pricing phenomenon is a byproduct of the third party payer strategy to begin with
[17:22:10] <ssi> further insulating the consumer from the prices isn't the way to fix that
[17:22:25] <archivist> I also thought the "public" hospitals over there were supposed to fix you up to an extent free or very late paying
[17:22:39] <ssi> see also milton friedman's four types of spending
[17:22:55] <Sairon> oh hell, he mentioned milton friedman
[17:22:58] <Sairon> it's all over now
[17:23:05] <ssi> what, is that like some new kind of godwin's law?
[17:23:12] <Sairon> lol. might be
[17:23:33] <ssi> "Oh no! someone's making a reasoned argument using actual economic theory rather than FUD!"
[17:23:51] <Sairon> i've noticed some folks get rabid when you start pulling out your choice of economist
[17:23:57] <Sairon> especially with friedman
[17:24:04] <furrywolf> archivist: anything other than I'm-unconsious-with-blood-spurting-out gets you in the hospital's "we don't care unless you have insurance" category, where you may never receive treatment, and it's a very, very, very expensive.
[17:24:17] <furrywolf> the hospital is required to treat you... they're not required to do it any time soon, properly, or affordably.
[17:24:49] <os1r1s> You can actually pay $1 per month to a hospital toward your bill and they have to accept it.

[17:38:23] <ssi> started with a foundation and framing
[17:38:52] <furrywolf> I'm supposed to be helping someone fix a house, but being crippled means it's not happening.
[17:39:15] <furrywolf> it has tweakers living in it... about the same effect as a fire, except the plastic pipe is still left.

[17:41:05] <_methods> big stuff
[17:41:07] <ssi> yeah
[17:41:12] <furrywolf> to fix it, he had to gut all the remaining drywall, fixtures, cabinets, etc, etc, etc... nothing left but bare framing... and the plastic pipe, because they didn't bother ripping it out, lacking scrap value.
[17:41:20] <ssi> I need to remake my prop crush plate and maybe extension
[17:41:22] <_methods> what you making with that?
[17:41:27] <ssi> they're aluminum, I want to make them in steel
[17:41:31] <ssi> should be almost 3x the weight in steel
[17:41:33] <_methods> how thick?
[17:41:53] <ssi> I'm not sure yet... if I just do the crush plate, I need to weigh what I currently have and do the math to see how much weight I actually need
[17:41:57] <ssi> maybe 1"
[17:41:59] <furrywolf> isn't weight bad?
[17:42:07] <ssi> yeah, but aft CG is worse
[17:42:10] <_methods> might be cheaper and easier to get someone to cut that out of plate
[17:42:22] <ssi> yeah might be... I'd have to turn it afterward though
[17:42:24] <_methods> i don't think we have any 1" 4130 though

[17:45:31] <ssi> that'd work
[17:45:43] <ssi> although I already have a hard time keeping my feet on the pedals when I'm upside down
[17:45:49] <ssi> lead boots would make that VERY hard :D
[17:45:49] <_methods> just avoid the water landings
[17:46:07] <ssi> I can bolt some lead to the engine mount
[17:46:12] <ssi> but I think a heavy crush plate is more effective
[17:46:18] <ssi> plus it'll give me some inertia on the prop
[17:46:28] <monttyle> Rab: I don't quite see how that works, though. Everything is hidden behind it.
[17:46:29] <ssi> I have a 12lb wood prop right now, very light, and it doesn't run remarkably smooth at low idle
[17:47:10] <furrywolf> and you don't like my suggestion of moving the wings back? :P
[17:47:12] <ssi> tonight I'll do the math and figure out exactly how much moment I need in order to get the cg inside the aft aerobatic limits at zero fuel
[17:47:26] <ssi> moving the wings back would actually make it worse!
[17:47:58] <ssi> it'd move the cg forward but it would also drastically reduce the tail effectiveness
[17:48:24] <furrywolf> how do you figure? you're moving the center of pressure rearwards, relative to the cg...
[17:48:51] <furrywolf> drastically, or slightly? :P
[17:48:53] <DaViruz> shorter tail moment arm?
[17:49:24] <ssi> yeah exactly
[17:49:37] <ssi> the cg limits are related to the center of pressure of the wing
[17:50:13] <Rab> monttyle, so assuming nomenclature of two Y-axis rail 'pods' riding on one Z-axis rail, I believe each pod is using Bell-Everman "ServoBelt" drive: https://www.youtube.com/watch?v=xh-AUPAWbPc
[17:50:17] <ssi> you want the cg forward of the center of pressure, so you have a forward pitching moment... the tailplane provides downforce to counteract the pitching moment
[17:50:26] <ssi> when the cg moves aft of the cp, you get divergent stability
[17:50:50] <ssi> the force the tail applies is obviously proportional to the arm
[17:50:50] <furrywolf> moving the wings back moves the cp back... it moves the cg back too, but not as much.
[17:51:04] <Rab> monttyle, so there's one belt running the length of the rail, and each Y-rail uses a stepper driving against the belt.
[17:51:11] <ssi> sure, but it reduces the tail moment by a fair bit
[17:51:34] <monttyle> Rab: I see, I see. And moving them relative to each other moves the tool.
[17:51:37] <furrywolf> by, what, a quarter inch? how far off is your cg? you're talking about a 4lb weight making a difference. :P
[17:51:39] <ssi> also there's the slight issue that you can't move the wings back in any reasonable way without completely redesigning the airframe
[17:52:01] <furrywolf> well duh. :P
[17:52:09] <PetefromTn_> Machining sacrificial jaws always seems like wasted time SIGH
[17:52:10] * furrywolf suggested it as the least practical option
[17:52:17] <ssi> it's definitely the least practical option
[17:52:24] <Rab> monttyle, correct. I'm using the mfg/trade names for the stuff since they're under patent; searching for those terms will give you lots more info.
[17:52:25] <_methods> until you do the job again
[17:52:31] <_methods> then you have those wonderful jaws
[17:52:42] <PetefromTn_> Oh yeah I forgot that part
[17:53:04] <Rab> There's an epic thread on CNCZone or somewhere, where people discuss DIY servobelt...lemme see if I can find it.

[17:54:37] <furrywolf> lol
[17:54:40] * monttyle is building it shaft-drive, since I care more about strength than speed, but the idea is the same, two motors on one rail pressing against a wedge.
[17:54:41] <DaViruz> oh
[17:54:53] <DaViruz> didn't know you bought one, cool
[17:55:00] <monttyle> And if you can patent that, a freakin' wedge... what can't you patent :p
[17:55:06] <ssi> furrywolf: he put a bunch of notes in the logs about a cross country he did
[17:55:11] <ssi> this was when it still had the subaru on it
[17:55:20] <ssi> he averaged 115mph on 6.9gph
[17:55:31] <ssi> and that was his 75% power cruise
[17:55:41] <ssi> now, to put those numbers in perspective
[17:55:56] <ssi> with the lycoming 150hp that's on there now, and a horribly inefficient underpitched prop,
[17:55:59] <furrywolf> seems it'd have two effects... first, it'd make the tail weigh less, in any orientation. of course, unless you have a seriously huge tail, you won't be able to fit much helium in it, so the actual weight reduction would be negligable. the secondary effect would be preventing you from putting any cargo or passengers in the same space, which definitely helps keeping the cg forwards...
[17:56:13] <ssi> my 75% power cruise is 178mph on 8.0gph
[17:56:22] <Rab> monttyle, you can buy steppers intended for Delta robots which have an acme-threaded bore going straight through the stepper. That might work well for this application.
[17:56:27] <ssi> at 115mph, I bur 3.2gph
[17:56:43] <ssi> there's no passengers or cargo in the tail anyway
[17:56:49] <ssi> and there's a pretty fair amount of space in the tailcone
[17:57:06] <ssi> be interesting to calculate the volume and do a thought experiment about what exactly it'd do
[17:57:27] <furrywolf> I can't imagine you getting more than a couple ounces of lift that way.
[17:57:31] <archivist> burst when you get to altitude error
[17:57:36] <DaViruz> it'd probably break havoc if they were to burst
[17:57:52] <Rab> But rack and pinion would probably work just as well.
[17:58:07] <ssi> shouldn't burst at altitude because it'd be constrained by the metal fuselage structure
[17:58:22] <ssi> it just would provide less force because the differential against the ambient pressure would be less
[17:59:11] <monttyle> Rab: Yep, I've got some shipping already. I'm combining one captive motor with one non-captive motor.
[17:59:27] <furrywolf> is your fuselage back there pressure-rated? :)
[17:59:41] <ssi> nope!
[17:59:47] <furrywolf> because, what, 8psi depending on how high your plane can go? :P
[18:00:07] <ssi> 15,000' DA is half pressure I believe
[18:00:10] <ssi> so 7.5psi ambient
[18:00:13] <archivist> vacuum
[18:00:23] monttyle is now known as monttyle-afk
[18:00:53] <furrywolf> so my guess of 8psi is pretty close. :P
[18:01:20] * furrywolf has no idea what the ceiling of ssi's plane is
[18:01:38] <ssi> I dunno what the ceiling is either but it's probably at least 15k
[18:01:46] <ssi> lemme see what vans' numbers say
[18:02:11] <ssi> they list the ceiling with 150hp as 19,300'
[18:02:19] <ssi> with 180hp they list 25,700'
[18:02:28] <_methods> is the cabin pressurized?
[18:02:29] <ssi> I have 150hp on mine
[18:02:31] <ssi> neg
[18:02:38] <_methods> you wear a mask up there?
[18:02:47] <ssi> yea above 12,500' you need o2
[18:02:49] <_methods> over 12,500
[18:02:50] <_methods> yeah
[18:02:53] <ssi> usually just a nasal cannula tho
[18:02:53] <_methods> i was gonna say
[18:02:59] <_methods> yeah up to 15k
[18:03:02] <_methods> you should be good
[18:03:09] <_methods> depending on medical condition

[18:04:47] <furrywolf> looking at that servobelt thing, they're using the teeth on the belt as a rack, and the teeth on the other side of the belt to drive against it? so if you glue the belt down, you don't have any belt stretch?
[18:05:10] <furrywolf> if they're at that altitude without preparing, they started out stupid.
[18:05:47] <_methods> people that play at those altitudes usually have a diff view on that
[18:06:51] <furrywolf> taking your plane to a height where you might need supplemental oxygen without supplemental oxygen is not evidence of a good decision making process.

[18:07:39] <Rab> furrywolf, there are two belts meshed together, one glued to the rack. The belts unmesh only where the stepper engages the top belt.
[18:08:26] <furrywolf> yeah, I figured that. :P
[18:09:26] <Pudlo> Is it possible to use belts to reduce the speed of a shitty high speed router to work better as a spindle?
[18:09:39] <Pudlo> Or would you spend more or good belts than a proper spindle…
[18:09:41] <Rab> Allegedly has a few engineering wins over a simple rack setup, tooth engagement being the big one.
[18:10:01] <furrywolf> my plan for a plasma table is to use aircraft cable on cylindrical fusees...
[18:10:18] <Rab> Pudlo, it's totally possible. But you might need a fair amount of reduction, depending on the final speed you need.
[18:10:22] -!- syyl has quit [Ping timeout: 246 seconds]
[18:10:33] <furrywolf> Pudlo: sure. many machines belt-drive the spindle. the only drawback is you have to build your own bearing assembly capable of dealing with the cutting forces and belt tension.
[18:11:39] <Rab> Routers are typically around 30K RPM, so if you need eg 5-7K for cutting aluminum you'll need a fairly large pully.
[18:11:41] <archivist> some even had variomatic pulleys in the head
[18:12:12] <archivist> and a more rigid frame
[18:12:23] <Rab> Pudlo, you'll need something analogous to this: http://reboots.g-cipher.net/spindle/
[18:12:39] <furrywolf> is a fusee still a fusee if it's cylindrical?
[18:12:51] monttyle-afk is now known as monttyle
[18:12:51] <Pudlo> Rab: hot damn that's a nice piece of work
[18:12:52] <archivist> something safe for wood may the breaking tools at a slower speed on aluminium
[18:12:52] <Rab> That didn't cost me very much, but took some time to build.
[18:12:58] <Rab> Pudlo, thanx g
[18:13:21] * furrywolf bets archivist can answer this
[18:13:50] <archivist> I know a fusee, define cylindrical
[18:14:09] <archivist> fusee is a special shape
[18:14:29] <furrywolf> a half-round groove around a cylinder
[18:14:34] -!- remstw has quit [Quit: brb]
[18:14:54] <Pudlo> Rab: what kind of belt is that, and where did you get your pulleys from?
[18:14:57] <furrywolf> serving the same purpose of a fusee, to wrap a cable or chain neatly in the groove, but without the taper and changing diameter
[18:15:13] <archivist> http://www.archivist.info/P3150762.JPG
[18:15:29] <Rab> Pudlo, MXL, standard small-scale stuff. I scavenged the pulleys from scrap equipment.
[18:16:01] <archivist> a plain barrel can be grooved the same and often was, no longer called a fusee though
[18:16:10] <furrywolf> that is, is there a special name for a continuous groove around the outside of a cylinder with a cable wound into it? :)
[18:16:24] <archivist> helix
[18:17:14] <archivist> most 8 day clocks had that
[18:17:21] <Rab> Pudlo, it's intended for micro tooling under 1/4" dia. Reducing the speed of a router will give you a lot of torque; if you want to transmit that to the toolhead you might investigate heavier belts like HTD, GT3, etc.
[18:17:33] <furrywolf> the guy on craigslist with the plasma table refuses to answer me, so the plan is still building my own.

[18:18:42] <Pudlo> Rab: Okay, cool. Yeah, I was looking at aliexpress. I'd probably have to do a multi-stage reduction to get this router to a decent speed. Might still work though.
[18:18:59] <furrywolf> I went through this with my machine, and ended up going with standard imperial timing belts due to unavailability of metric parts.

[18:20:19] <furrywolf> archivist: a fusee has the shape it does to linearize the non-even force of a spring.
[18:20:20] <furrywolf> grr
[18:20:22] <furrywolf> Connor:
[18:20:46] <archivist> Connor, to compensate for the varying spring tension with amount of wind
[18:20:58] <Connor> ok
[18:21:29] <archivist> somewhere on the server is the text to explain the curve
[18:22:20] <furrywolf> Connor: when a spring is fully wound, it pulls with a lot of force. when the spring is almost unwound, it pulls with barely any force. while the ideal clock escapement would run at the same rate regardless of applied force, the real-world has reality applied to it. so, to compensate for changing spring force, the diameter changes, like a variable reduction.
[18:22:45] <furrywolf> the larger diameter is when the spring has the least force, and the smaller diameter when the spring has the most force, giving constant torque.
[18:24:28] <furrywolf> archivist: I saw a funky spring a while ago... it was a long strip with a curve to it, like the blade on a tape measure, wound between two wheels geared together, one flat, one curved. the flattening of the curve formed into the strip seemed to provide the storage....
[18:24:32] <furrywolf> any idea what that's called?
[18:24:51] <furrywolf> it provided a constant force for the entire length
[18:25:10] <archivist> tensator
[18:25:29] <archivist> or that is the trade name
[18:25:56] <furrywolf> never seen it before or since. :)
[18:26:04] <archivist> used in barriers and other pull out devices

[18:27:08] <furrywolf> hrmm, doesn't seem to work like that. I think this one used the curve in the strip and a crowned pulley...
[18:27:28] <archivist> you will have seen barriers pulled out to enclose delineate an area in a bank or shop etc
[18:28:04] <furrywolf> but, yeah, the overall mechanism does look the same. maybe the crowned version was just a refinement.
[18:29:26] <furrywolf> it was in a crank-powered generator... you crank the big spring for a while, then it runs the generator at a constant speed.
[18:31:37] <monttyle> sounds like an old gramaphone.
[18:32:10] <archivist> fusee maths http://www.collection.archivist.info/searchv13.php?searchstr=rawlings

[18:57:41] <cradek> linuxcnc runs under rtai or rt-preempt kernels, not xenomai
[18:58:11] <stb> well, there's the xenomai runnable version in git, but it is a bit old
[18:58:47] <stb> and that pertains to my question, apparently there is no interest to support xenomai in future releases?
[18:58:48] <cradek> yeah there may be an old branch - it's unmaintained
[18:59:05] <cradek> well it sounds like there's some interest (you)
[18:59:12] <cradek> nobody I know of is working on it
[18:59:12] <stb> well, yes
[18:59:25] <cradek> why do you want that?
[18:59:27] <stb> that's what i was afraid of
[18:59:42] <stb> i've been playing with xenomai and rt-net

[19:01:19] <stb> well, i was coming to that... as a second question
[19:01:20] <cradek> yes I think mesa has several options
[19:01:35] <stb> and mister epler has been doint that
[19:01:40] <stb> doing
[19:01:55] <cradek> what's your overall goal?
[19:02:27] <stb> well, as I said, I want to have my mills controlled solely via ethernet
[19:03:32] <stb> and as i said, i have a set up with xenomai+rt-net+linuxcnc that is up and running
[19:03:45] <stb> the only thing is to do my own driver
[19:04:00] <stb> however, since you brought it up
[19:04:32] <stb> i just installed for a test the 2.7 with the pre-empt wheezy
[19:05:11] <stb> i do get pretty horrible jitter on that
[19:05:35] <stb> anyway, is there any benchmarks on that rt-preempt and ethernet
[19:05:53] <skunksleep> Xenomai and rt-net was a pain. And only supported a few nice. Rt-preempt is a lot more flexible.
[19:06:04] <skunksleep> What is horrible?

[19:07:38] <cradek> actually that's probably fine, < 10% of the servo cycle
[19:08:11] <stb> i haven't tried all the tweaks etc, you could probably make it work, however, i was more interested how well the ethernet is working with the pre-empt thingy
[19:08:21] <cradek> you might find some bios settings that would improve it
[19:08:31] <stb> cradek: yes, those are to be tested
[19:08:44] <cradek> I haven't tried it but people keep reporting good results with hm2 eth on rt-preempt

[19:09:13] <cradek> I use the mesa pci cards because I've been using them for years and years
[19:09:30] <skunksleep> I have had good luck with a 7i80
[19:10:36] <stb> skunksleep: and what kind of latency do you have?
[19:11:49] <skunksleep> I have tested it with a lot of hardware. Anywhere from 30us to 80us.
[19:12:18] <stb> okay, so the ethernet keeps up with that, good to know
[19:13:08] <stb> okay then, i'll have a go with the pre-empt kernel and checkout eplers work
[19:13:19] <skunksleep> Peter from mesa has machines running 3 to 4khz servo periods for months testing
[19:13:38] <stb> okay, that sound pretty good

[19:28:33] <stb> cradek: exactly, i'm exploring the choices i have
[19:28:48] <stb> and what can be achieved
[19:30:56] <skunksleep> Just going by the mesa hm2-eth read write times.. Not taking into account the latency. You would be limited to a few khz step frequency.

[19:32:01] <stb> yes, what do you think is the limiting factor for the read write times?
[19:32:32] <skunksleep> That is above my pay grade...
[19:33:08] <os1r1s> stb: I'd guess the latency induced by the network stack.
[19:33:47] <stb> os1r1s: that's my guess too
[19:34:39] <stb> still, would like to know the exact bottleneck
[19:34:46] <os1r1s> stb: Many enterprise software vendors introduced their own protocols and stack to improve latency.
[19:35:16] <os1r1s> For clustering operations and what-not
[19:35:29] <stb> you mean like ethercat and like
[19:35:32] <skunksleep> What do you mean by parallel port and proprietary thingy?
[19:35:45] <os1r1s> So I'm assuming something could be done, but nothing is going to come close to a real pin you can hit

[19:36:23] <stb> i mostly mean that the hardware is proprietary, mesa is nice since it's fpga and afaik you can do your own hdl
[19:36:26] <cradek> with a parallel port you can set an output pin and generate a step pulse with one instruction
[19:37:11] <cradek> if you want some more complex interface you give up on making software step pulses, and that's a VERY good thing because software stepgen kind of sucks
[19:37:46] <os1r1s> stb: I'd not heard of that one, but that looks like a good example.
[19:38:27] <stb> cradek: yes, but what exactly do you then recommend instead?

[19:43:41] <stb> cradek: yes, but as skunksleep said, it's geared towards servo, and what do you do if you have need for steppers
[19:43:52] <cradek> skunksleep didn't say that
[19:44:05] <cradek> you use a hardware stepgen like is already done and working
[19:44:17] <cradek> was that your actual question all along?
[19:45:05] <stb> what exactly do you mean by hardware stegpen?
[19:45:07] <cradek> linuxcnc has supported hardware stepgens for ... probably nearly 20 years?
[19:45:26] <Tom_itx> stb, it's generated from a fpga
[19:45:30] -!- Pudlo1 [Pudlo1!~Adium@wn-res-nat-129-97-125-30.dynamic.uwaterloo.ca] has joined #linuxcnc
[19:45:39] <Tom_itx> from commands sent to it
[19:45:54] <Tom_itx> rather than sending the pulses out the parallel etc port
[19:46:07] <stb> yes and you send say, speed or absolute position on ethernet etc and the fpga generates the steps?
[19:46:19] <Tom_itx> uh huh
[19:46:20] <cradek> yes exactly
[19:46:32] <Tom_itx> at a much higher frequency
[19:46:34] <cradek> or over a pci slot or pci-e slot or epp
[19:46:52] <stb> okay, and what would you recommend in a case where i have say couple of servos and a couple of steppers?
[19:47:03] <Tom_itx> a mesa card
[19:47:15] <cradek> totally
[19:47:23] <Tom_itx> 5i25, 7i90 etc would do it
[19:47:26] -!- Pudlo has quit [Ping timeout: 248 seconds]
[19:47:34] <Tom_itx> lots of them will
[19:47:49] <_methods> pcw recommended to me the 7i76 and the 7i77 i think
[19:47:51] <Tom_itx> just depends on your configuration as to which one you want
[19:47:56] <_methods> to save on the 5i25 combo
[19:48:01] <stb> okay
[19:48:18] <_methods> for stepper servo combo
[19:48:19] <PetefromTn_> Oh nice my Anodizing materials shipment came in from Caswell Plating...
[19:48:34] <Tom_itx> i'm using the 7i90 because i'm still sending my commands out the parallel port to it
[19:48:44] <stb> still, i hope you can bare with my curiosity here, how does the hw-stepgens work?
[19:48:53] <stb> i haven't really studied this
[19:48:56] * Tom_itx gives PetefromTn_ a hasmat suit
[19:49:12] <cradek> some take position commands and some take velocity commands
[19:49:16] <cradek> some can take either
[19:49:18] <os1r1s> PetefromTn_: When you dump the acid in the tank, it likes to splash.
[19:49:22] <os1r1s> FWIW
[19:49:36] <stb> and then they generate the pulses per some algorithm they have
[19:49:38] <cradek> every servo cycle you command a position or velocity, and read back the actual feedback position
[19:49:53] <PetefromTn_> you always add the acid to the water as I recall
[19:49:57] <stb> okay, that's what i thought
[19:50:03] <cradek> yes then they make nice smooth pulses until the next servo cycle
[19:50:08] <Tom_itx> mine are sending out 40k pulses per sec
[19:50:19] <Tom_itx> iirc
[19:50:34] <Tom_itx> maybe that's per rev? i forget now
[19:50:34] <os1r1s> PetefromTn_: You do, but it still splashes going in
[19:50:46] <cradek> the pulse rate just doesn't matter anymore once you have this design
[19:50:56] <Tom_itx> absolutely
[19:51:02] <stb> still one more question, is there some other downsides to sw stepgen?
[19:51:14] <Tom_itx> lower rates
[19:51:25] <cradek> it's really only useful with a direct parallel port connection
[19:51:30] <Tom_itx> more resources taken from the pc
[19:51:45] <Tom_itx> slower performance
[19:51:45] <cradek> it has no upside except it's free
[19:51:46] <stb> Tom_itx: lower rates because of what?
[19:51:48] <PetefromTn_> I should think the splashing would be determined by the manner in which it is added ;)
[19:52:04] <Tom_itx> because you can only send them out the port so fast
[19:52:33] <Tom_itx> the fpga typically runs at 50Mhz
[19:52:46] <os1r1s> PetefromTn_: I thought so too. But when I poured the acid into the tank, it splashed. And the clothing it splashed upon developed holes.
[19:52:54] <Tom_itx> and can parallel process
[19:53:20] <PetefromTn_> I got extra jeans ;)
[19:53:21] <stb> yes, i've done some fpga stuff myself
[19:53:45] <stb> hmm, okay
[19:54:08] <Tom_itx> it's a no brainer once you've used one
[19:54:13] <stb> yep
[19:54:33] <stb> well, uh oh, i wouldn't say hdl is exactly easy, but
[19:55:04] <Tom_itx> no brainer meaning the choice of parport over a mesa card
[19:55:24] <stb> but to recap, my last question, hopefully; if you could
[19:55:31] <stb> Tom_itx: ah :)
[19:55:33] -!- ve7it [ve7it!~LawrenceG@S01060014d19d0b68.pk.shawcable.net] has joined #linuxcnc
[19:55:39] <Tom_itx> beside that, the 7i90 gives you 72 io
[19:56:23] <stb> if you had an ethernet based system, in which you could do servo and sw stepgen for say a 9 axis machine, that would not be of interest to anyone?
[19:57:05] <Tom_itx> hardly think it can be done more efficiently
[19:57:27] <cradek> it's not clear to me that software stepgen over ethernet is *impossible* but it's certainly very inferior to the system we already have
[19:57:56] <stb> cradek: you just forced me to ask more
[19:58:02] <cradek> I did no such thing
[19:58:05] <stb> :)
[19:58:07] <Tom_itx> hah
[19:58:07] <PetefromTn_> It would seem to me to be real hard to beat a mesa card setup with HW stepgen but I am certainly no expert
[19:58:47] <stb> okay, the hw stepgen presumably has some algorith that does the generation of steps
[19:58:48] <Tom_itx> it offloads the work to the card so the pc doesn't have as much to do
[19:58:59] <stb> yes
[19:59:41] <Tom_itx> so how many more ways are you gonna ask the same thing?
[20:00:01] <stb> but is it of no concern that there is one trajectory planner in lcnc and then some form of a linear etc planner in the fpga etc hw
[20:00:10] <Tom_itx> because the answer will be the same
[20:00:43] <cradek> bbl
[20:01:45] <Tom_itx> read about hostmot2
[20:02:14] <stb> what about it?
[20:02:31] <Tom_itx> http://linuxcnc.org/docs/2.7/html/drivers/hostmot2.html
[20:02:48] <Tom_itx> that tells you the supported functions
[20:05:42] <stb> okay
[20:06:29] <stb> presumably the sw stepgen in lcnc is simply moved to the mesa hw
[20:06:56] <Tom_itx> you wouldn't use sw stepgen with the driver loaded
[20:07:24] <stb> yes, i meant that the sw functionality is moved to the mesa hw
[20:07:29] <Tom_itx> yup

[20:22:52] <PetefromTn_> I just received my deburring wheel for my bench grinder I oredered.
[20:23:17] <PetefromTn_> Looks like I chose the right one because it seems to work exactly like the ones we used in the shop locally so WIN!!
[20:23:42] <PetefromTn_> great for polishing steel finishes and works on ally too

[20:30:11] <PetefromTn_> yeah they are really nice
[20:30:34] <ssi> they're part of standard toolkits for building aluminum airplanes :)
[20:30:40] <PetefromTn_> this is a 9S fine wheel
[20:30:51] <ssi> I use mostly medium wheels
[20:31:06] <PetefromTn_> they can take away subtle tooling marks quickly too which is nice
[20:31:08] <ssi> they're aggressive enough that you can move metal if you bear down on it, but fine enough that you can polish with a light touch
[20:31:18] <PetefromTn_> yup exactly
[20:31:24] <PetefromTn_> are yours the red ones?
[20:31:34] <ssi> when I polish aluminum, I do light passes with the scotchbrite and then a cloth wheel with rouge

[21:36:15] <PetefromTn_> isn't there a little calculator in the program or in Pncconf or Stepconf I can't remember
[21:37:04] <furkanyilmaz11> My axises is working well in my configuration
[21:37:20] <furkanyilmaz11> Should I open new stepconf again?

[21:44:58] <furkanyilmaz11> No problem bro :)
[21:45:47] <furkanyilmaz11> I think machine just need to know how much pulses needed for one rev. But there are more configs

[21:59:01] <furkanyilmaz11> andypugh welcome, I have a question and I think thats your expertise :)
[21:59:39] <furkanyilmaz11> Is that scale parameter in .ini file is pulses per rev value for joint axis
[21:59:41] <furkanyilmaz11> ?
[21:59:47] <andypugh> I got the new MB to biit from CD. I got it to the end of the Ubuntu 12.04 installer. It rebooted. And rebooted, and…
[22:00:31] <andypugh> furkanyilmaz11: Technically the SCALE in the INI is anything the HAL file wants to use it for.
[22:00:35] -!- Pudlo1 has quit [Quit: Leaving.]
[22:01:01] -!- jvrousseau has quit [Ping timeout: 246 seconds]
[22:01:15] <andypugh> Your HAL file _could_ Use SCALE to set the G-code units. But that would be silly.
[22:01:26] <PetefromTn_> Woohoo just received my tracking number from Captainhindsight for my Black, Magenta, Cyan, and Yellow dies. This should be getting interesting around here pretty soon.
[22:01:32] <andypugh> So, yes, typically INI file “SCALE” is pulses per engineering unit.
[22:02:19] <furkanyilmaz11> andypugh then how should I callibrate my joint axis? I think machine just need to know how much pulses needed, so there are no parameter needed I think for joint axis I think. But how can I enter the stper per rev value?
[22:02:29] <furkanyilmaz11> Umm ok
[22:02:47] <furkanyilmaz11> So that means I will set the scale value right?
[22:02:53] <andypugh> If you are talking about steppers, then it is pulses per mm or pulses per inch.
[22:03:24] <PetefromTn_> he has a delta robot andy
[22:03:31] <furkanyilmaz11> I am talking about open loop servo so its communucating with pc same as stepper
[22:03:36] -!- Valen has quit [Ping timeout: 276 seconds]
[22:03:44] <andypugh> Ideally you would look at the INI file and see exactly what the HAL file is using it for, but stepgen.scale is pulses per inch or mm (depending on machine units)
[22:04:24] <furkanyilmaz11> ok let me to take a look
[22:04:28] <andypugh> If it’s a Delta robot, then it might be pulses per rev or pulses per degree (even possibly, pulses per radian)
[22:04:40] <furkanyilmaz11> Yes I know
[22:05:00] <furkanyilmaz11> If I enter the pulses per rev value
[22:05:17] <furkanyilmaz11> Or pulses per degree value its gonna be ok
[22:05:28] <furkanyilmaz11> But I have no idea about where to enter it
[22:05:30] <andypugh> You probably need to look inside the kinematics file to see whether it is expecting the input in degrees, radians, or revolutions.
[22:06:00] <furkanyilmaz11> Ok I will take a look the kin file and hal file
[22:06:10] <furkanyilmaz11> I will back in 5 min
[22:06:22] <andypugh> You can, if you want, set the values direct in the HAL file. I tend to, on my own configs.
[22:06:25] <andypugh> Your choice.
[22:07:12] <furkanyilmaz11> How?
[22:09:04] <furkanyilmaz11> in hal file there is a line like setp stepgen.1.position-scale [AXIS_1]SCALE
[22:10:24] <furkanyilmaz11> I think that means I should set the SCALE parameter in .ini file. But is it per rev or per deg
[22:13:23] <andypugh> I can’t tell if it is revs or degrees. You could always try both..
[22:14:11] <furkanyilmaz11> ok I am tryiing right now
[22:14:25] <andypugh> [AXIS_1]SCALE in the HAL file means “Look in the ini file for a value, and use it here”. You can use numerical values directly, and you can also create your own INI file sections and entries to be used in the HAL file, if you want.
