[00:01:39] <DaViruz> no, it isn't
[00:01:47] <Valen> its 42C here
[00:02:10] <Valen> our weather department has just added 2 colours to its temperature display map to account for over 55C
[00:06:04] <t12> https://www.dropbox.com/s/usu4rywt851lewn/2013-01-10%2015.15.13.jpg
[00:06:07] <t12> look at all them disks
[00:09:11] <Valen> theres the odd one there
[00:09:16] <Valen> they doing anything interesting?

[00:09:51] <t12> we have some insane microscope camera that does 8kx8kx25fps effectively
[00:09:58] <t12> so even transient storage of the datasets takes alot
[00:10:03] <Valen> thats a pretty decent camera
[00:10:04] <t12> like 10tb/24hours or so sometimes
[00:10:12] <Valen> compressed at all or raw?
[00:10:15] <t12> the raw camera is 400fps 4kx4k
[00:10:18] <Valen> 10tb isn't that much
[00:10:31] <Valen> 3.5Gb drives are only $150 now
[00:10:33] <t12> than its mathed up to 8k8k
[00:10:43] <Valen> i remember when I got a 2Gb drive
[00:10:45] <t12> its not alot, but the logistics of dealing with it is hard
[00:10:54] <t12> like how do you actually move the dataset around effectively
[00:11:02] <t12> 10gbe works, but costs alot and
[00:11:06] <Valen> now you can get a 2TB drive for half what i paid for it, a quater in real terms
[00:11:14] <t12> like 10gbe sfp+ fiber is about 3.5k/link
[00:11:22] <Valen> yeah screw that lol
[00:11:33] <t12> thats not including the nics
[00:11:43] <t12> then theres backing it all up..
[00:11:53] <Valen> you can get cheap infiniband cards these days
[00:11:59] <t12> ya
[00:12:04] <t12> theres alot of convergance 10gbe/IB cards
[00:12:07] <t12> where you can use them for either
[00:12:29] <Valen> thats new
[00:12:35] <t12> i think mellanox is into that
[00:12:42] <Valen> I wanted the infiniband for latency reasons with DRBD
[00:12:57] <t12> we use it for big simulations sometimes
[00:13:11] <t12> IB latency is nice
[00:14:37] <t12> did you get to try it for drbd
[00:14:45] <t12> i'd expect actual disk latency to be the issue before 1gbe
[00:14:49] <t12> unless its for ssd or something
[00:15:18] <Valen> its just the way drbd is done

[00:16:01] <t12> ah ok
[00:16:13] <Valen> so if i can shave any time off it at all for a few hundred $ why not
[00:16:36] <t12> were you just gonna do ib host to host
[00:16:57] <Valen> yeah
[00:17:06] <t12> ah yeah thats def worthwhile
[00:17:15] <t12> ib switch cost is heavy until you're saturating the switch upfront
[00:17:49] <Valen> its not totally needed, but its really cool lol
[00:18:06] -!- rob_h has quit [Ping timeout: 276 seconds]
[00:18:10] <Valen> I do wish I could mangle the thing thats running DRBD for me so i could use raw IB, not IPoIB
[00:18:46] <t12> hum
[00:18:47] <Valen> I run bonded-rr gbit at the moment
[00:19:11] <t12> i guess it depends on how modular the drbd code is
[00:19:22] <t12> if the network layer can be abstracted transport over ib wouldnt be so bad
[00:19:33] <t12> i dunno if ib has native reliable transport streams or not
[00:19:58] <PCW> "PCW: If I comment out the flash_start call, does that mean I can dry-run the rest of the code without worrying about breaking stuff?"
[00:19:59] <t12> otherwise you kinda have to reimplment tcp on top of ib
[00:20:24] <ReadError> man im lovin hsmworks
[00:20:28] <PCW> Andy no that wont work, you need to skip the "commits"
[00:21:20] <Valen> oh drbd can do it just fine
[00:21:44] <Valen> i'm using ganeti to manage my VM's and it takes care of setting up DRBD for me
[00:21:51] <Valen> but ganeti doesn't know about IB
[00:22:59] <t12> i'm just assuming drbd depends on tcp for stream integrity from a gif on their page
[00:24:04] <Valen> I know they have added IB support recently
[00:24:11] -!- joe9 has quit [Ping timeout: 255 seconds]
[00:24:20] <Valen> well not that recent
[00:24:36] <Valen> http://www.drbd.org/users-guide/s-replication-transports.html
[00:24:55] <t12> oh yeagh
[00:25:02] <t12> cool it directly supports it then
[00:25:25] <Valen> so what are you doing taking high speed microscope photos for 24 hours anyway?
[00:27:12] <t12> EM tomography and EM single particle reconstruction
[00:27:42] <t12> em tomo is essentially a CT scan of a single cell or object by electron microscope
[00:28:01] <t12> em single particle reconstruction is prepare a sample of say, some protein
[00:28:06] <t12> take a zillion pictures of the single proteins
[00:28:21] <t12> align the pictures to eachother and you can gradually back out the outside surface shape
[00:28:35] <t12> i think the record is down to around 4A for some virus coats now
[00:30:43] <t12> half of it is the science of the output of all that
[00:31:01] <t12> the other half is the development of that camera and various things about the microscope to make everything work

[00:37:38] <Valen> I spose your going to be doing a fair bit of seeking style access not so much streaming
[00:38:14] <Valen> has anybody managed to get round-robin style bonding working through a switch yet?
[00:39:57] <t12> like just non LACP aggregates?
[00:40:02] <t12> its not so seeky
[00:40:11] <t12> alot of it just jamming huge datasets into memory and working on them there
[00:40:31] <t12> the micrographs are large, but you end up cutting out little 200x200ish pixel images and thats where all the math happens
[00:40:34] <t12> so you can put alot in ram
[00:40:44] <Valen> i mean if you lacp it you can get 2x data rate to 2 hosts but not to 2 hosts
[00:40:50] <Valen> bah
[00:40:53] <Valen> not to 1 host
[00:41:03] <Valen> so 2x gbe ports != 2gbe
[00:41:08] <t12> yeah with non-lacp ittl just RR though
[00:41:11] <t12> (i think)
[00:41:22] <Valen> yeah but that won't go through a switch
[00:41:31] <Valen> switches tend to out-of order the packets
[00:41:33] <t12> ittl go through a real switch!
[00:41:45] <Valen> doesn't go through my cisco 2960s

[02:41:28] <skunkworks> no - the spindle sticks out for the rails about a foot - that is all I am compinsating for

[03:35:02] <RyanS> Not sure what to search for, I want to research what signals etc DB25 breakout boards communicate to the stepper drivers? Are breakout boards nothing more than an opto-isolated pass through between the PC and drivers?
[03:35:59] <jdh> mostly
[03:39:21] <jdh> http://www.nbglin.com/cnc25.htm
[03:50:48] <tjtr33> a Linuxcnc parport can be cfg'd to be in or out or 'x' mode, that changes what is presented to your breakout board right away. see Hal manual Ch.10
[03:51:23] <tjtr33> then, look at your stepper driver, they have similar functions, but wildly differnt pin locations
[03:51:37] <jdh> unless you have a g540 :)

[09:40:33] <mrsun> wouldnt using a set screw with an angled top be the best to tighten gibs ?

[09:48:16] <cncbasher> mrsun:use a small ball bearing between the screw and gib plate
[09:48:30] <mrsun> hmm that is an idea =)
[09:48:47] <mrsun> but would leave just a very small contact area to begin with and it would dig in ?=
[09:48:57] <mrsun> or do i drill a small dimple in the gib ?
[09:49:04] <cncbasher> this self adjusts to whatever angle is needed
[09:49:30] <cncbasher> most have a small dimple in the gib yes
[09:50:18] <mrsun> http://lh5.ggpht.com/_ozT1G3WqXg4/TUqsPuzQqeI/AAAAAAAALKM/HweM0rgDKQU/s800/gib.jpg http://lh5.ggpht.com/_ozT1G3WqXg4/TUqsPuzQqeI/AAAAAAAALKM/HweM0rgDKQU/s800/gib.jpg
[09:50:28] <mrsun> cncbasher, and you sure that works good? :)
[09:50:37] <mrsun> so i dont bite myself in the arse doing that :P
[09:50:40] <archivist> the taper in the bottom of the dimple helps tighten the gib if you are lucky/unlucky
[09:51:10] <cncbasher> iv'e done it like that for years , not had any problems
[09:51:47] <archivist> I have had directional friction differences on some slides
[09:52:03] <cncbasher> dont like the idea of the lower edge of the gib not being angled ,
[09:52:27] <cncbasher> i can see that being a problem and jamming up
[09:52:30] <mrsun> gonna try and make new gibs for the mill as the people who made them 1 .. made them to thin, 2 the "height" of the gib differs 2mm over its length :P
[09:52:48] <cncbasher> needs to be angled to fit properly , similar to the top
[09:53:17] <mrsun> cncbasher, its the angle of the set screw i mean from those pictures, that they havent angled the bottom of the gib to make it fit i find kinda stupid =)
[09:53:32] <mrsun> the set screws on my mill is like the first picture
[09:53:35] <mrsun> round nosed
[09:54:41] <cncbasher> yes i agree , hence the reason to use a ball bearing , far much better than a round end on the scree

[09:55:37] <archivist> I rather like taper gibs because of the endwise restraint
[09:55:40] <mrsun> as the set screw would just rotate against the ball bearing

[09:56:51] -!- RifRaf has quit [Remote host closed the connection]
[09:56:53] <archivist> you need some form of restraint (dimples) else the gib can slide (stick to the stationary part)

[09:57:45] <mrsun> archivist, there are in the original gibs, but looks mostly like they have just tightened the gib screws hard to make dimples in it :P

[09:58:27] <cncbasher> yea that drawing is amateurish and not good practice
[09:59:48] <mrsun> but so, get some ball bearings then that fit inside the gib screw holes and new gib screws that fit agains the bearings better, and new gibs
[09:59:51] <mrsun> :P
[10:00:01] <mrsun> and drill a small dimple for each bearing ball
[10:00:15] <cncbasher> yes
[10:00:17] <archivist> I did come across a new (to me) taper gib, tape is not length but across and pushed in sideways
[10:00:53] <mrsun> i guess one could make "tapered" gibs by having two gibs
[10:00:59] <mrsun> and pushing them against eachother
[10:01:22] <mrsun> gapered a couple of degrees each
[10:01:30] <mrsun> hard to lock them in place tho :P
[10:01:43] <mrsun> prone to jamming i guess
[10:01:59] <archivist> dunno how you would arrange the push out screws
[10:02:27] <mrsun> hehe would only be push in screws :P

[10:03:53] <mrsun> if there was more space one could just make a stationary tapered shim also

[10:04:14] <mrsun> but at 3.75mm maximum space i think that would be hard =)
[10:04:53] <archivist> tapers gibs self jam if the push out screw is not hard up against the end

[11:18:10] <jthornton> HarryHood, you can use single ended on the encoder
[11:18:37] <HarryHood> is it less accurate this way?
[11:19:00] <jthornton> less resistant to noise
[11:19:09] <HarryHood> I could just connect the rest of the pins, is that the reason for my machine stepping away from true 0?
[11:19:50] <jthornton> if you have them I would connect them, the machine may not be tuned as well
[11:20:12] <HarryHood> thats my question really, is it something in the tuning or encodeR?
[11:21:16] <HarryHood> if I tell the machine to go x5, then x0 and repeat. its like, 2 steps left one step right
[11:21:22] <jthornton> did you tune the axes with halscope?
[11:21:42] <jthornton> is this a servo machine?
[11:21:42] <HarryHood> I used my old tuning from the 5i20
[11:22:14] <HarryHood> just plugged in numbers
[11:22:52] <HarryHood> i just dont see how the encoder is offsetting
[11:23:21] <jthornton> does the DRO agree with the position?
[11:23:50] <HarryHood> it shouldnt really matter how accurately the machine moves, so long as it the encoder reads dro reads 0 the orientation of the motor shafter should be the same

[11:27:44] <HarryHood> if I start the software and assume all motor shafts are at 0 and the keyway of the motor shafts are in the 12O'clock position. then send motor to x1 and back to x0 repeated for example 10 times, when I sendit back to zero, the shaft sits at 4 O,clock
[11:27:50] <HarryHood> lol i know that feeling
[11:28:31] <pcw_home> If you are using single ended encoders, you should make sure
[11:28:33] <pcw_home> that the 7I77 is jumpered for single ended encoders
[11:28:34] <jthornton> ok, so the position and the DRO do not agree after moving, this does sound like noise on the encoder lines
[11:28:51] <HarryHood> both axis are equally offsetting
[11:28:57] <jthornton> and wait for Peter to magically show up at 3 am
[11:29:08] <HarryHood> I assume the jumper is wrongly set for only using a b z
[11:29:43] <HarryHood> I need to either hook up a/ b/ z/ OR relocate jumper
[11:29:52] <pcw_home> I think default is differential
[11:30:30] <HarryHood> differential refers to a a/ b b/ z z/? and single ended is a b z?
[11:30:44] <pcw_home> yes
[11:30:49] <HarryHood> ughhh
[11:30:52] <HarryHood> one jumper
[11:30:59] <HarryHood> I knew it was simple

[13:01:17] <V0idExp> Because it accelerates and slows at each point, and can't manage to reach full speed. All points are commanded to be reached at speed F2000, but rarely I can reach those speeds.
[13:02:10] <V0idExp> I noticed that with less detail, or said in other terms, with more space between points, actual speeds increase
[13:02:47] <V0idExp> Is there any way to tell LinuxCNC to don't slow down at each point but keep going at commanded speed?

[13:09:52] <V0idExp> Thanks! Reading it now
[13:10:20] <DJ9DJ> not sure about that, but thats at least what I understood ;)
[13:10:46] <V0idExp> Already have a question... :) Does it throws points away?
[13:12:17] <DJ9DJ> i think it does not throw points completely away, but yes, it decreases accuracy
[13:12:18] <V0idExp> Imagine a triangle. What my NGC program generator does it is adding very much detail at angles and almost no points at straight lines. (ideally only 2, but being the figure got from machine vision software, sometimes it does not see "ideally straight" lines)
[13:13:23] <DJ9DJ> i think linuxcnc cannot optimize your gcode...
[13:13:53] <V0idExp> No, no! My GCODE is already optimized this way :)
[13:14:09] <V0idExp> The only problem is that linuxcnc doesn't go at nominal speeds, and that's what I need
[13:15:00] <DJ9DJ> yeah, if you have very many points next to each other, the machine will slow down to "hit" each point exactly
[13:15:08] <V0idExp> Is there a way to force it to don't try to correct speeds based on geometry, but just to try to go through commanded points at speeds that I programmed?
[13:15:20] <V0idExp> Ok, understood
[13:15:27] <V0idExp> Well, this explains many things :(
[13:15:45] <Tom_itx> sounds like a crappy gcode optimizer
[13:15:55] <DJ9DJ> but perhaps some of the old linuxcnc experts might help you better than me, i am just a noob without much experience
[13:16:16] <V0idExp> So, what you suggest, is to add more tollerance to G64 commands?
[13:16:18] <DJ9DJ> nor in cnc stuff, neither with linuxcnc ;)
[13:16:50] <DJ9DJ> yes, that was my intentional idea. set something like G64 Pxxxx
[13:16:58] <DJ9DJ> where xxxx i the tolerance
[13:17:02] <DJ9DJ> *is
[13:17:38] <V0idExp> thank you!
[13:17:53] <DJ9DJ> no prob :)
[13:22:31] <jthornton> V0idExp, have you read this?

[15:21:22] <Mr_Wolfsl> hi cradek how can I import the tool-length in the kinematics?
[15:21:27] <Mr_Wolfsl> my haldata is empty
[15:22:38] <cradek> that's kind of the wrong approach. you probably want to put your tool lengths along W and set up your kinematics so a change in W is always along the tool vector
[15:23:21] <cradek> otherwise you will get jumps in position when the offset changes, which will make your machine disagree with you
[15:23:32] <Mr_Wolfsl> I put the length in the colum W in my tool table
[15:24:14] <cradek> ok, good
[15:25:11] <cradek> so in your gcode you do G43 and you'll see W change. then you can issue G0 W0 and you'll get a nice move that applies the tool length
[15:25:25] <Mr_Wolfsl> when I put the pivot-length + tool-length manually in the .hal it's OK
[15:25:36] <Mr_Wolfsl> yes I have the G43
[15:26:19] <Mr_Wolfsl> I see the W change in the GUI not with the kins
[15:26:36] <cradek> well you don't want the tool length in the hal file, because it changes! like all the other offsets, that is a part of the joint position your kins gets.
[15:27:43] <cradek> changing an offset will NEVER cause a change that kins can see, because changing an offset does not move the machine. on your next programmed move you'll get the motion with respect to the new offset. that's why I said you then issue G0 W0
[15:28:08] <cradek> are you following that? it's critical you understand it
[15:28:23] <Mr_Wolfsl> ok i will try

[15:31:34] <cradek> tried what?
[15:31:48] <Mr_Wolfsl> put G0 W0 in the Gcode
[15:32:21] <cradek> you'll have to loopback the W motion pins in the hal
[15:32:47] <cradek> since W isn't a real joint with real feedback
[15:35:56] <Mr_Wolfsl> it's already done

[16:40:44] <mrsun> hmm new gib made huge difference, but i think i got to small ball bearing balls, got the presure point for the gib to low even lower then the original gibscrews .. might be fixable by making a 3mm "flat" in the gibs at the center of the gibscrews .. hmm
[16:41:25] <mrsun> should be 3.5 or 3.6mm balls insted but cant get that anywhere here :/
[16:42:11] <cncbasher> yea come in through the screw holes with a long drill and get the angle in the gib
[16:43:22] <cncbasher> yes 3.5mm balls or there about works for me
[16:43:26] <mrsun> yeah but there is so little clearance that i cant get a drill in there with any kind of power thingie :/
[16:48:49] <mrsun> 3.5 doesnt seem to be a very common size :P
[16:49:17] <mrsun> more then on ebay
[16:49:19] <mrsun> but then i have to wait
[16:49:21] <mrsun> a long time :P
[16:49:35] <mrsun> but damn i could tighten the new gib ALOT more then the old before binding :P
[16:49:46] <mrsun> beforei had like .5mm rattle of the table at the ends
[16:50:26] <mrsun> now i got about 0.01 in one end and like 0.1 at the other most extreme ... dont know why i cant tighten it up more in that end tho might be the dovetails that are out that much also :/
[16:51:23] <mrsun> using 3.5 insted of 3 i guess would lift the center about 0.25mm dont know if that is enough... :/
[16:51:42] <mrsun> the dovetail of the table is a little to small .. should have been 1mm longer and it would be alot better

[18:50:55] <mrsun> http://imagebin.org/242524 point A and point B is like 150mm from the center, in each direction when the table is at point A and i rock it i get about 0.1mm of "rocking" at point A, at point B i get about 0.03mm of rocking, im guessing in relation to the center point (the end mill) this rocking is very amplified am i right? at these points what would be acceptable values of "rocking" of the table? :)

[18:56:26] <mrsun> the green and red represents the table in the far extremes of the travel to left and right
[18:56:41] <andypugh> No, movement at the tool will be slightly less than at points A and B
[18:56:53] <andypugh> (About half)
[18:57:00] <mrsun> andypugh, huh ?
[18:57:25] <mrsun> cant measure the movement at the tool and if i rock the table at the far extremes the movement at the tool (center black point) should be very small shouldnt it? :)
[18:57:29] -!- Connor has quit [Ping timeout: 255 seconds]
[18:57:33] <andypugh> The ditance from the pivot (the edge of the black block) is less for the tool than for your measuement point
[18:58:07] <andypugh> We are vehemently agreeing by using different words.

[18:58:42] <mrsun> cant tighten the gibs any more for point A tho, table binds. ..
[18:58:50] <mrsun> might be better if i scrape the gibs real flat tho
[18:58:58] <mrsun> as they can differ some in height as its just flatstock ive used
[19:00:05] <andypugh> Scraping is traditional :-)
[19:01:28] <mrsun> the dovetails might need some touchup also ... ive scraped the flat surfaces of everything so its very very flat for being a sieg X1 mill :P
[19:02:38] <mrsun> but the dovetails are sooo small its hard to even get a very small scraping tool into them :P
[19:03:10] <mrsun> but anyways what would be acceptable values in rocking of table on a mill :/
[19:03:18] <mrsun> there has to be some "slop" else everything just binds up
[19:03:20] <mrsun> but how much

[22:27:55] <cradek> beautifully done
[22:28:54] <andypugh> I was worried that it might be too hard, but once CBN-ed through the case it was fine.
[22:29:26] <andypugh> (I didn't make the worm part, I hasten to add, just machined down the shaft, shortened it, and bored the hex in the end)

[22:32:55] <andypugh> The plan is to have a hex collar around the motor shaft, and then I can have a neat installation with the moto r shaft inside the worm shaft, rather than a really long extension tube with a coupling in it, like this one:

[22:36:07] <andypugh> Of course this relies on me managing to get a hex exactly coaxial with a bore.
[22:36:53] <andypugh> In theory I could make the hex spigot on the lathe too :-)

[22:39:05] <cradek> do you want a slightly tapered hex? that'd be no harder with your setup...
[22:39:14] <andypugh> I considered making the socket pentagonal, just for fun.
[22:39:29] <cradek> ha
[22:39:36] <andypugh> No, the whole point is to have no end thrust on the motor shaft.
[22:39:49] <cradek> oh, gotcha
[22:40:01] <andypugh> Though I accept that your plan means that I can have zero backlash.
[22:40:11] <cradek> sure
[22:40:33] <cradek> hard to meet both goals
