[04:49:27] <CaptHindsight> unstable RTAI patch for 3.8 kernel posted earlier
[04:50:58] <CaptHindsight> just got a stable kernel for RT-PREEMPT and X and KDE up with all power management + ACPI off on the A10 APU
[04:52:00] <CaptHindsight> we should have some good RT-PREEMP latency numbers later today

[07:15:13] <Thiel> hi i try to update from 2.5.2 to 2.6 master and get an error on hostmo2-firmware modebus5.lib
[07:15:52] <Thiel> do i need to activate both deb in the sources
[07:16:06] <Thiel> http://buildbot.linuxcnc.org/
[07:18:19] <Thiel> hostmot2-firmware but it is not installable
[07:29:12] <jthornton> are you trying to install master (there is no 2.6) from a deb?
[07:30:02] <Thiel> deb
http://buildbot.linuxcnc.org/ lucid master-rt
[07:30:04] <Thiel> deb-src
http://buildbot.linuxcnc.org/ lucid master-rt
[07:30:18] <Thiel> jthornton: this is what i added to the repros
[07:30:32] <Thiel> and disabled the 2.5 branche
[07:31:21] <jthornton> that looks correct
[07:31:28] <Thiel> i need the remap its only in the master in the branch i need to go over the O<xx> sub
[07:33:30] <Thiel> do i need to enable both or only one at the time
[07:33:42] <jthornton> both of what?
[07:34:43] <Thiel> there are 2 URl
[07:34:58] <Thiel> the hook on both or only on one
[07:35:07] <jthornton> yes both master-rt IIRC should be there
[07:35:39] <Thiel> still no hostmot2-firmware deb
[07:36:08] <Thiel> i there a ppa for this
[07:37:29] <jthornton> file:///home/john/emc-dev/docs/html/drivers/hostmot2.html#_installing_firmware
[07:38:53] <skunkworks> http://www.linuxcnc.org/docs/devel/html/drivers/hostmot2.html#_installing_firmware
[07:38:56] <skunkworks> :)
[07:39:12] <Thiel> it this is on your system
[07:39:54] <Thiel> http://emergent.unpythonic.net/01272896838
[07:39:55] <jthornton> LOL, I gave a local link
[07:39:59] <Thiel> what is this for
[07:40:13] <Thiel> its on toms side
[07:40:50] <jthornton> you would have to ask jepler what that is for it is his
[07:41:34] <Thiel> there is no packet hostmot2-firmware allone
[07:42:09] <Thiel> i may need to uninstall all the 2.5. hostmot2-firmware first
[07:44:52] <Thiel> no hostmot2-firmware but it is not installable
[07:52:39] <Thiel> no hostmot2 even on the s.5.2
[07:52:56] <Thiel> so now i need to get the git working
[07:54:08] <jthornton> I thought you did that via the synaptic package manager

[10:49:17] <CBJamo> Hi, I'm trying to get a mesa 5i22 set up with a trio of 7i39s, and I can for the life of me figure out how to configure them in the wizard. I suspect that I'm getting the pinouts wrong.
[10:49:48] <JT-Shop> pncconf?
[10:49:56] <CBJamo> yes
[10:50:13] <jdh> there is no wizard, only yourself <insert better oz reference here>
[10:50:21] <JT-Shop> lol
[10:50:44] <CBJamo> oh, fun, can someone point me to the documentation for the config files?
[10:50:50] <JT-Shop> can you be more specific on the question?
[10:51:30] <CBJamo> Like I said, I'm pretty sure that I've got the pin configurations wrong.
[10:51:36] <JT-Shop> the Integrators manual has the configuration information as well as the hostmot2 man page
[10:51:52] <CBJamo> Ok, I'll take a look at that
[10:51:57] <jdh> wrong pins, or wrong connectors, or what?
[10:52:43] <CBJamo> wrong pins, between the 7i39 and the 5i22. I'm fairly confident that the motor and hall sensors are hooked up right.
[10:53:13] <pcw_home> CBJamo: I almost guarantee that a 3x 7I39 configuration will require a custom bitfile
[10:53:16] <JT-Shop> what kind of card is the 7i39?
[10:53:38] <JT-Shop> YEA Peter to the rescue!
[10:53:40] <jdh> 7I39 Dual 250W 3 Phase BLDC driver
[10:53:41] <CBJamo> The 7i39 is a dual channel bldc controller.
[10:54:02] <CBJamo> pcw_home: Ok, good to know.
[10:54:04] <JT-Shop> ok, it didn't ring a bell with me
[10:56:28] <CBJamo> pcw_home: By bitfile, do you mean custom firmware on the fpga?
[10:58:07] <pcw_home> Yes
[10:59:11] <CBJamo> pcw_home: Alright, how should I set about writing one?
[11:00:05] <pcw_home> What do you want on the last connector?
[11:00:59] <CBJamo> for now, all I have planned are endstops.
[11:02:52] <pcw_home> I can make a 3x7I39 (or 4X) config but need to know i f you have special I/O on last connector (non GPIO)
[11:03:16] <pcw_home> also whether you have a 5I22-1 or 5i22-1.5
[11:04:28] <CBJamo> I have a 5i22-1, I don't expect to be using the last conector for anything but endstops, estop, possibly a keypad for jogging.
[11:05:03] <CBJamo> But not a mpg or analogue joystick.
[11:06:39] <pcw_home> OK I can make 7I39x4 config for the 5i22-1 sometime today
[11:07:21] <CBJamo> Sweet, thanks for the help.
[11:10:29] <ssi> pcw_home: you think a single superport firmware could be fit to a s3a 200?
[11:13:53] <ssi> I dunno if there's any fancy features in the s6 that the s3a doesn't have that might hang me up
[11:14:01] <ssi> or (more likely) if there'll be size constraints
[11:22:37] <pcw_home> Should fit OK (not too many channels though)
[11:24:13] <ssi> if I could make it run a 7i77 alone, I'd be happy
[11:24:19] <ssi> and I don't even need the extra sserial on the 7i77
[11:25:11] <pcw_home> Probably (7I77 just has 6 encoders and 3 sserial ports so is pretty small)
[11:25:27] <ssi> cool
[11:25:30] <ssi> I may tackle that soon
[11:25:38] <ssi> I have the s3a-200 on beaglebone working
[11:25:50] <ssi> it's got a 24 pin io expansion header on it
[11:26:02] <pcw_home> what interface to BB?
[11:26:08] <ssi> SPI or I2C easily
[11:26:19] <pcw_home> i2c is too slow
[11:26:21] <ssi> there's a GPMC port, but we haven't worked out the device tree overlay for it
[11:26:26] <ssi> I have SPI working now
[11:30:01] <pcw_home> SPI probably needs a common protocol that gets along with most SOC SPI interfaces
[11:30:32] <ssi> well the way I have it setup now, I'm using spidev
[11:30:47] <ssi> there's a spidev device node, and I can write/read it as a file,
[11:30:51] <pcw_home> Probably useless
[11:30:53] <ssi> or I can do bidir transfers using ioctl
[11:31:05] <pcw_home> way way way too slow
[11:31:11] <ssi> how fast does it need to be?
[11:31:15] <ssi> I can also write a custom device driver
[11:31:21] <ssi> but that'll take some work
[11:33:25] <ssi> the other option is to get gpmc going, and then I can do it over a 16 bit address/data muxed memory interface
[11:33:29] <ssi> but that'll take a lot more work
[11:33:41] <ssi> fortunately we're already working on it for another application
[11:34:02] <pcw_home> most SOC SPI interfaces are buffered and have common non pipelined control registers so you cannot do things like change frame sizes without significant overhead, so some kind of efficient wrapper for HostMot2 data/address needs to be devised that does not change frame sizes
[11:36:31] <ssi> hm
[11:36:40] <ssi> nothing's ever easy is it
[11:36:43] <pcw_home> I am looking at a block transfer scheme where the first 32 bit frame contains the (16 bit) start address, read/write command, data frame count etc.
[11:36:45] <pcw_home>
[11:36:47] <pcw_home> The GPMC is nice but I worry that it will interfere with the NAND flash
[11:36:55] <ssi> the flash has to be disabled
[11:37:00] <ssi> which is fine, I don't mind running off usd
[11:37:34] <ssi> I need to get the hm2 source checked out and actually look at it :P
[11:38:18] <pcw_home> GPMC is probably the fastest (if there are enough pins in the 24 you have available)
[11:38:50] <ssi> no the 24 pins I mentioned are separate from what's attached to BBB
[11:38:58] <ssi> those 24 pins I intended to make a superport
[11:39:13] <ssi> here's the board:
http://ebrombaugh.studionebula.com/embedded/bcc/index.html
[11:40:07] <pcw_home> I think its possible to run sserial on the PRU as well (with a "little" work)
[11:41:36] <pcw_home> though I think you would have to run the remotes at 3.68 or 4 Mbaud instead of 2.5
[11:44:00] <ssi> I can't for the life of me figure out how to clone the git repository at
http://git.linuxcnc.org/gitweb?p=hostmot2-firmware.git;a=summary
[11:44:10] <ssi> is that even the right repo?
[11:44:12] <ssi> it's over a year old
[11:44:58] <pcw_home> so if the FPGA has GPMC connections I would use them ( you will need to make a 16 --> 32 and 32--> 16 bus shim)
[11:45:33] <pcw_home> I would just download the source from mesa
[11:45:45] <ssi> I don't have that url
[11:45:47] <ssi> was trying to find it
[11:46:19] <pcw_home> just download the support package for any FPGA card
[11:46:24] <ssi> ah ok
[11:47:37] <Tecan> http://www.cnczone.com/forums/joes_cnc_model_2006/38220-joes_computer-numeric-control_4x4_hybrid.html
[11:54:49] <ssi> pcw_home: the 5i25 support package looks like it only has bitfiles in it
[11:55:08] <ssi> oh I see there's a source zip
[12:03:56] <cbjamo_> pcw_home: I just remembered that I'll need 4 step/dir sets on the 4th connector.
[12:05:10] <cbjamo_> pcw_home: They'll be driving 4 of these:
http://www.pololu.com/catalog/product/2133 to control the steppers for my extruders.
[12:05:49] <pcw_home> ok, can you send a email to Mesa with what you want? (to tech)
[12:06:30] <cbjamo_> pcw_home: Sure, do you need any other details, besides what we've talked about here?
[12:06:51] <pcw_home> what pins you want the stepgens on
[12:08:27] <cbjamo_> doesn't matter, the cable is going to go into a 7i42, then the stepper boards and the endstops, etc.
[12:08:54] <cbjamo_> tech@mesanet.com right?
[12:09:09] <pcw_home> yeah
[12:14:12] <cbjamo_> Sent, and thanks again for the help.

[12:18:52] <dosas> i've also tried some programming in c
[12:18:59] <dosas> also doesn't work
[12:19:28] <IchGuckLive> what if you just load a standard hal
[12:19:41] <IchGuckLive> and check with halmeter
[12:19:52] <dosas> the card i use is pci to paraqllel with MCS 9865
[12:20:11] <dosas> how do i do this
[12:20:24] <IchGuckLive> lspci -v is ehat adress
[12:20:33] <IchGuckLive> What
[12:20:58] <IchGuckLive> do you got any reaction or nothing
[12:20:59] <dosas> I'm new to thsi stuff
[12:21:05] <dosas> so how do i load standard hal
[12:21:14] <IchGuckLive> dosas where are you from usa europ
[12:21:16] <dosas> do you mean the kernel module?
[12:21:21] <dosas> germany

[12:21:52] <dosas> kk
[13:21:34] <IchGuckLive> nice talking by till tomorrow
[13:50:10] <andypugh> The lack of a sense of scale on eBay auctions strikes again...
[13:50:12] <andypugh> https://picasaweb.google.com/lh/photo/XZwy6BMFtwIx7p6RMn-3ztMTjNZETYmyPJy0liipFm0?feat=directlink
[13:50:32] <ssi> hahahahaha
[13:50:36] <ssi> you're bad at this game
[13:51:48] <andypugh> Actually, it just makes it more of a bargain in this case (£7). My machine can handle it.
[13:52:12] <ssi> excellent
[13:52:30] <cradek> wow
[13:53:21] <cradek> that was not a cheap cutter when new
[13:55:09] <andypugh> Indeed not. I can't decide if it is HSS-tipped or carbide tipped. Probably the former.
[13:57:57] <skunkworks> andypugh, what project is that for?
[13:58:32] <andypugh> Errr, well, it was cheap?
[13:59:05] <FinboySlick> andypugh: That's the best reason.
[13:59:12] <andypugh> I have a friend who needs a new head traverse gear for his Hayes Diemaster, so that was the excuse.
[13:59:13] <ssi> :D
[13:59:18] <FinboySlick> Awesome + cheap = buy.
[13:59:42] <skunkworks> andypugh, how is x coming?
[14:00:02] <andypugh> That same friend reports that the castings are back from the foundry.
[14:00:11] <FinboySlick> Sadly, (awesome + cheap) does not apply often to storage space for all the stuff one buys.
[14:00:28] <skunkworks> andypugh, neat!
[14:00:38] <andypugh> And the preloaded version of the Y-axis screw is in the post.
[14:00:41] <FinboySlick> andypugh: Castings for a custom mill?
[14:01:02] <andypugh> (I found that I could squeeze a 16mm screw, with preload, in where the 12mm Y screw now is.
[14:01:12] <andypugh> I am sure I will find another use for that 12mm
[14:01:28] <andypugh> FinboySlick: Castings to convert the existing mill to CNC.
[14:02:12] <andypugh> Pattern for Y
https://picasaweb.google.com/lh/photo/iQeBNoJzloy1Gy-ua9oghNMTjNZETYmyPJy0liipFm0?feat=directlink
[14:02:46] <andypugh> Y casting:
https://picasaweb.google.com/lh/photo/abzo-Io3-DMkbvox4DLo19MTjNZETYmyPJy0liipFm0?feat=directlink
[14:03:05] <FinboySlick> Neat. I guess one would have to be pretty motivated to sandcast their own full-sized mill frame.
[14:03:11] <andypugh> Z castings
https://picasaweb.google.com/lh/photo/yL_HbM82TA6ALJAZvehoBNMTjNZETYmyPJy0liipFm0?feat=directlink

[14:03:46] <FinboySlick> Neat motors too.
[14:04:24] <andypugh> Yeah, what kind of looney do you take me for? It's a lathe I am planning to scratch-build.
[14:05:27] <andypugh> Though I was >this< close to bidding on that lovely Rivett 608 earlier
[14:06:06] <andypugh> Stuff it! I just bid for it.
[14:06:24] * FinboySlick starts daydreaming of a workplace where he could undertake these kinds of projects.
[14:07:00] <ssi> I wish I had casting facilities
[14:07:18] <ssi> I have a friend that's really into letterpress... it'd be fun to cast some new tabletop presses
[14:07:26] <FinboySlick> I imagine that past 3-4 liters of steel, things get kind of iffy for home casting.
[14:07:27] <skunkworks> andypugh, when did you get the probe?
[14:07:43] <FinboySlick> (well, iron)
[14:07:59] <skunkworks> there are a few small foundrys locally that will suposidly cast by the pound...
[14:08:07] <ssi> yea but for a wee machine like this:
[14:08:07] <ssi> http://excelsiorpress.org/photos/Kelsey/KelseyJunior/junior%201.jpg
[14:08:11] <ssi> might be feasible
[14:08:12] <andypugh> skunkworks: A few months ago. It was cheap on eBay.
[14:08:30] <skunkworks> andypugh, the only way to go :)
[14:08:32] <ssi> skunkworks: what kind of DIY is that?!
[14:08:45] <ssi> if you're not mining your own ore, you're a poseur
[14:08:46] <ssi> :P
[14:08:52] <FinboySlick> ssi: Isn't it Myfordboy who does great aluminium castings?
[14:08:55] <skunkworks> heh
[14:09:09] <ssi> betas me
[14:10:05] <FinboySlick> ssi:

[14:10:06] <Tecan> (M95bhPrDwA0) "Metal Casting at Home Part 10 Another Day in my Home Foundry" by "myfordboy" is "Howto" - Length: 0:09:25
[14:11:03] <ssi> neat
[14:11:16] <andypugh> And he knows how "moulding" is spelt.
[14:12:33] <jdh> superfluous letters FTW
[14:12:40] <ssi> lol
[14:12:51] <andypugh> I have done some casting, I have worked in a couple of places with their own foundries (university metallurgy departments) and it is great fun.
[14:13:06] <ssi> looks like fun
[14:13:14] <ssi> it's been on my list of things to do for awhile
[14:13:20] <FinboySlick> Watching him work, it looks almost meditative.
[14:13:27] <jdh> I've done lead casting, sort of.
[14:14:03] <ssi> I work in broad-casting
[14:14:06] <ssi> sort of the same thing, right? :(
[14:14:21] <jdh> more or less. mostly less
[14:14:25] <ssi> mostly
[14:16:59] <ssi> I think I could probably do aluminum at home without too much hell
[14:17:01] <ssi> iron would be tough
[14:17:23] <CaptHindsight> http://www.3ders.org/articles/20130610-china-develops-worlds-largest-laser-3d-printer.html
[14:18:09] <ssi> his parts come out really nice
[14:18:26] <CaptHindsight> it's not clear from the article, but it looks like they only sinter the outline of the part, then bake the sand+resin mix to make the mold
[14:24:43] <FinboySlick> Hmmm, if they only sinter the outline, does it mean the part is filled with unsintered material?
[14:25:33] <Loetmichel> if tha part is soaked with a lower melting metal afterwards thats not a problem
[14:26:21] <Loetmichel> like sintering stainless steel dust and then filling it up with molten brass
[14:26:40] <CaptHindsight> "their 3D printer only prints an outline of each layer to make the carbide of resin coated sand on the contour ineffective."
[14:27:16] <CaptHindsight> "Then they put the printed sand into a 180ËšC furnace, a traditional method for curing and stripping to get a prototype or mold."
[14:27:18] <FinboySlick> I have trouble parsing that sentence ;)
[14:27:26] <CaptHindsight> yeah, me to :)
[14:27:28] <FinboySlick> Well, the previous one.
[14:28:00] <CaptHindsight> " relying on making the outline ineffective,"
[14:28:22] <CaptHindsight> have to find a Chinese article and translate
[14:28:25] <Loetmichel> ah, i understand
[14:28:33] <CaptHindsight> sounds like a poor translation
[14:29:17] <Loetmichel> it only prints a "parting layer" in the sand, acure the whole block afterwards in an oven
[14:29:23] <Loetmichel> ingenious ;-)
[14:29:37] <CaptHindsight> if the sand is a sand + resin mix then all you need to do is sinter the outline
[14:29:38] <Loetmichel> -a+and_
[14:30:02] <CaptHindsight> then bake the sand + resin mix to harden a large volume
[14:30:07] <Loetmichel> right
[14:30:11] <Loetmichel> like i said
[14:30:13] <CaptHindsight> yeah , pretty nifty
[14:30:28] <FinboySlick> The way I understand it though, it would make part handling pre-curing quite difficult.
[14:30:37] <FinboySlick> Or do they move the entire block?
[14:30:42] <Loetmichel> FinboySlick: i think so
[14:30:47] <CaptHindsight> if the cured layer is very fragile
[14:31:12] <Loetmichel> because all sand moulds i know are VERY fragile
[14:31:21] <CaptHindsight> they must cure a thick enough layer to make it tough enough for handling
[14:31:40] <Loetmichel> so move it as whloe to the oven, THEN vaccuum the uncured outer layer away, then cure the remaining parts
[14:32:03] <CaptHindsight> if you cure a layer 1/3 inch thick vs the whole part it still saves you time
[14:34:13] <Loetmichel> or even print a top mold, a bottom mold, a "sand part", then cure the whole block and take the molds apart
[14:34:35] <Loetmichel> thanks to the parting layer the "sand part" will just fall out
[14:37:28] * FinboySlick looks at the database cluster he's putting together, then at awesome machinery...
[14:37:55] <FinboySlick> The choices between something you're good at and something you like doing yet are inept at ;)
[14:39:34] <Jymmm> Or, something you're damn good at but hate doing =)
[14:42:25] <FinboySlick> Jymmm: Skill level is relative. I'm definitely the best around for my physical location, but I could never consider myself 'damn good at' my current field considering the absolutely brilliant people I get to interact with online on a daily basis.
[14:44:11] <Jymmm> FinboySlick: There's nothing wrong with ignorance, it's just "not knowing" and you can always learn =)
[14:44:55] <Jymmm> FinboySlick: I've always hated the negative connotation of the word as some may use it.
[14:44:56] <FinboySlick> Jymmm: Heh, I have to learn to get stuff done. I learn the rest easy enough.
[14:45:10] <CaptHindsight> FinboySlick: you must not work at the DMV :)
[14:46:02] <FinboySlick> CaptHindsight: Easy there, some people may be insulted.
[14:46:08] <FinboySlick> ;)
[14:46:33] <FinboySlick> I won't specify if it's the DMV or me ;)
[14:46:41] <ssi> casting is fascinating :P
[14:47:25] <FinboySlick> ssi: Yeah, everytime I start watching that stuff I'm lost for an hour or two.
[14:47:33] <ssi> yep
[14:47:49] <ssi> this guy is good at it too
[14:47:52] <FinboySlick> ssi: I waste quite a bit of time watching Keith Fenner work too.
[14:48:13] <FinboySlick> Despite his lack of love for cnc.
[14:51:09] <FinboySlick> CaptHindsight: Incidently, our Canadian equivalent to the DMV is actually pretty good, as much as I hate to praise government services.
[14:52:28] <ssi> FinboySlick: yeah you've pretty much killed my productivity for the rest of the day
[14:52:31] <ssi> maybe week
[14:53:37] <FinboySlick> ssi: Not sure if it's the same guy, but I found some pretty in-depth tutorials on mixing your own sand and everything else.
[14:53:47] <ssi> I just watched a video of his on mixing sand
[14:54:05] <ssi> I really wish I could be in wichita next week :/
[14:54:23] <jdh> I can't imagine anyone saying those words.
[14:54:30] <FinboySlick> I'll drink lots and lots of soda so I can cast my own mill ;)
[14:54:41] <ssi> I don't think you want to cast with cans
[14:54:46] <ssi> pretty sure they're 90% slag
[14:55:36] <FinboySlick> Heh, don't know, but they're probably close to 30% paint ;)
[14:55:59] <ssi> from what I've read, cans really just burn up and oxidize so badly that they're not worth melting
[14:56:03] <ssi> swarf too
[14:56:08] <FinboySlick> So by the time you're casting, you're so high you don't care ;)
[14:56:27] <jdh> anyone used a Gas Pycnometer?
[14:56:27] <andypugh> Something that would be funny to see at Wichita (and unlikely) would be a Beaglebone controlling one of the monster Cinci macines.
[14:56:40] <ssi> andypugh: I don't think we're far enough along yet
[14:56:44] <ssi> but we're definitely making progress
[14:57:28] <CaptHindsight> how are the BBB's working out so far for Linuxcnc?
[14:58:02] <ssi> looking promising
[14:58:13] <andypugh> CaptHindsight:

[14:58:14] <Tecan> (n2IoHOZipLU) "BeagleBone + BeBoPr + LinuxCNC + MendelMax Printing" by "Charles Steinkuehler" is "Tech" - Length: 0:03:12
[15:00:02] <ssi> I'm looking into how to shoehorn HM2 firmware into this guy:
[15:00:02] <ssi> http://ebrombaugh.studionebula.com/embedded/bcc/index.html
[15:04:15] <CaptHindsight> does the BBB have enough ummph to run a display while hosting Linuxcnc?
[15:04:33] <FinboySlick> CaptHindsight: By the looks of it, yes.
[15:04:59] <ssi> yeah it should be able to just fine
[15:05:06] <ssi> however the hdmi framer eats a lot of pins
[15:05:11] <ssi> so you may want to stick with ssh tunneling X
[15:05:27] <CaptHindsight> can't for this application
[15:06:48] <CaptHindsight> DLP projector and motor control
[15:07:27] <CaptHindsight> user interface is fine over ssh
[15:11:37] <JT-Shop> ouch, I just manicured my thumbnail with the flap wheel on the angle grinder
[15:11:53] <ssi> fun
[15:13:02] <andypugh> As long as it was just the nail...
[15:13:51] <JT-Shop> well just a bit of the epidermis went with the nail
[15:23:22] <JT-Shop> NICE! I just put a custom Send To in my windblows machine to my BP Mill /nc_files
[15:23:41] <JT-Shop> right click on a file and send it to the mill
[15:23:43] <Jymmm> JT-Shop: Like up to the elbow? armpit?
[15:24:05] <JT-Shop> Jymmm: well I stopped pretty fast
[15:24:23] <cbjamo_> I am working on a machine that has 2 joints for each axis. (like a gantry with each side driven, but on all 3 axis) Am I correct in thinking that I will need to use non-trivial kniematics?
[15:24:29] <CaptHindsight> zedboard vs BBB shootout, maybe I can bring them both to the cncfest
[15:24:33] <Jymmm> JT-Shop: Yes, YOU did, but did the angle grider?
[15:25:05] <JT-Shop> I'm still able to type with both hands...
[15:25:17] <Jymmm> ...and all nine fingers =)
[15:25:22] <andypugh> cbjamo_: Not necessarily. There is the option to use a non-usual version of LinixCNC
[15:26:15] <andypugh> cbjamo_: The joints_axes3 branch has a trivial kinematics that handles multiple motors per axis.
[15:26:23] <andypugh> (gentrivkins)
[15:26:32] <cbjamo_> andypugh: right, am I going to have to compile that? and if so do I just find it on github?
[15:27:00] <Jymmm> andypugh: Have you ever seen/used this? Does BOTH: raise window and snap to
http://coderage-software.com/zooom/
[15:27:20] <Jymmm> andypugh: I'm not sure if it's still in development.
[15:27:27] <Jymmm> active^
[15:27:31] <andypugh> Yes, you need to compile it. Instructions here:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC#Getting_the_source_with_git
[15:28:21] <cbjamo_> andypugh: How angry is linux cnc going to get if I have the live-cd instal already on this machine?
[15:28:25] <andypugh> Jymmm: I have never tried it. I don't tend to install any UI tweaks.
[15:29:21] <andypugh> cbjamo_: It doesn't care, the compiled version will be run-in-place and will only run if you run the rip-environment script first, then start it from the command line. But you can open the same config files.
[15:29:41] <cbjamo_> andypugh: ok, thanks
[15:32:16] <Xfriend> how is work hobbycnc with linuxcnc ??
[15:33:53] <JT-Shop> what is hobbycnc?
[15:35:31] * JT-Shop loves having gremlin in touchy
[15:38:06] <Xfriend> HobbyCNC EZ Driver Board Kit
[15:38:39] <CaptHindsight> http://www.hobbycnc.com/products/hobbycnc-ez-driver-board-kit/
[15:39:26] <JT-Shop> I can't see why it won't work
[15:40:54] <JT-Shop> LOL they hide the name of the driver chip
[15:41:17] <JT-Shop> looks like a simple project to do
[15:42:38] <JT-Shop> Xfriend: what are you building?
[15:43:14] <Xfriend> JT-Shop: I have a cnc machine with tb6560 chinese version
[15:43:46] <Xfriend> and I want to make work
[15:44:12] <Xfriend> sad story :( lol....!!
[15:45:48] <CaptHindsight> that ez board looks like it uses the TB6560
[15:46:36] <CaptHindsight> without any extra heatsinks
[15:47:48] <CaptHindsight> http://www.sainsmart.com/sainsmart-cnc-tb6560-4-axis-stepper-motor-controller.html?___store=en&___store=en
[15:48:06] <CaptHindsight> only $63 for 4 axis, but a little noisy
[15:48:59] <Xfriend> my work like a noise fan is the room
[15:49:06] <andypugh> Xfriend: Still not working?
[15:49:06] <cradek> JT-Shop: what the hell, hiding the chip number
[15:49:23] <JT-Shop> yea, that's crazy
[15:49:48] <CaptHindsight> someone might copy the design without spending the $70
[15:50:04] <andypugh> Xfriend: I thought you would have it soved by now.
[15:50:05] <Xfriend> andypugh: x axis and y axis works perfect but z axis get stuck and run
[15:50:23] <andypugh> can you elaborate on "get stuck and run"?
[15:50:40] <Xfriend> like run and stop
[15:50:53] <Xfriend> not even a 1mm
[15:50:58] <andypugh> What happens if you turn the speed right down?
[15:51:12] <Xfriend> I get the same
[15:51:30] <andypugh> And if you reduce the accelleration>
[15:51:40] <Xfriend> I put 100% 75% and 25%
[15:52:12] <Xfriend> do not move
[15:52:42] <andypugh> Where did you "put 25%"
[15:53:46] <Xfriend> on the switches
[15:53:46] <Xfriend> like on and off
[15:53:46] <andypugh> That is not at all what I meant.
[15:53:46] <Xfriend> oh..!!
[15:53:46] <andypugh> Turn the board back up to max.
[15:53:46] <Xfriend> okay
[15:54:01] <andypugh> Configure the software with much lower accelleration and velocity settings on [AXIS_2] in the INI file.
[16:05:20] <Xfriend> andypugh: okay I change the setting I put 240 max_velocity
[16:05:26] <Xfriend> andypugh: and it move much better then before
[16:06:07] <andypugh> what acceleration
[16:06:19] <Xfriend> andypugh: But I can't home any axis because the X axis it move too far
[16:06:36] <andypugh> Do you have home switches?
[16:06:41] <Xfriend> andypugh: AXIS_2 max_velocity 240
[16:06:48] <Xfriend> andypugh: no
[16:07:22] <andypugh> you might find that you need a lower acelleration to get to the best speed.
[16:07:50] <andypugh> (acelleration and velocity are different settings in the same part of the INI)
[16:07:52] <Xfriend> andypugh: and also I get a big noise out of the stepper motors
[16:08:14] <andypugh> Stepper motors are quite noisy.
[16:08:21] <Xfriend> yes
[16:09:14] <Loetmichel> andypugh: use sine "stepping" -> quiet steppers ;-)
[16:09:52] <andypugh> http://www.youtube.com/watch?v=lCh-LC0UCM0
[16:09:52] <Tecan> (lCh-LC0UCM0) "Super Mario Bros. CNC Music :-)" by "Chris Hellyar" is "Tech" - Length: 0:01:54
[16:13:51] <Xfriend> andypugh: I wish my stepper motor make that music
[16:15:00] <Tom_itx> i wonder how long it took to figure out the rates to get the tune
[16:16:24] <andypugh> There is software that converts MIDI to G-Code
[16:16:44] <Tom_itx> i figure it was probably something like that
[16:16:56] <andypugh> Anyway Xfriend I think you may need to turn off homing if you have no home switches.
[16:17:38] <Tom_itx> 93° F Partly Cloudy
[16:17:55] <andypugh> If you set the HOME_SEARCH velocity and HOME_LATCH velocity to zero in the INI then the machine will home where it is at the moment you press the buton.
[16:17:57] <Tom_itx> 100 tomorrow
[16:19:33] <Xfriend> okay
[16:22:35] <Xfriend> andypugh: now I can home the axis but I get a message "program excees machine maximum axis Z "
[16:22:48] <Xfriend> andypugh: now I can home the axis but I get a message "program excees machine maximum on axis Z "
[16:23:05] <andypugh> Yes, the demo configs do that. It's a "feature".
[16:23:23] <Tom_itx> heh
[16:23:42] <CaptHindsight> Tom_itx: did you order any tornado's for next week?
[16:23:48] <andypugh> You need to jog down to a bit above the imaginary workpiece, then press the "touch off" button to tell the machine that that is the point you ar going to call Z = 0 for this job.
[16:24:12] <Tom_itx> it's hard to say but it's turned warm so maybe that will be the trend for a bit
[16:24:18] <Tom_itx> mid 90's all week
[16:25:48] <CaptHindsight> Tom_itx: did you guys have a spring? we went from snow to rain and still almost to freezing at night
[16:26:10] <Tom_itx> somewhat
[16:26:25] <Tom_itx> more spring than last year for sure and definitely more rain
[16:26:34] <Tom_itx> but we're still in need of more
[16:26:39] <CaptHindsight> same in China, snow was still in piles when it hit 80's
[16:26:42] <Tom_itx> at least the river is up a bit
[16:26:55] <Tom_itx> you could walk across it and not get wet last year
[16:27:20] <Tom_itx> they had the dam up for the river festival this last week so it was nice and full
[16:27:31] <Tom_itx> with plenty going over the spillway
[16:28:58] <Tom_itx> they just reopened it maybe a month ago after rebuilding the bridge and new dam
[16:29:22] <Tom_itx> added a fish passage to comply with the fed
[16:30:16] <CaptHindsight> whats the airport code for Wichita?
[16:30:19] <Tom_itx> ict
[16:30:20] <CaptHindsight> ICT?
[16:30:32] <Tom_itx> it's not that big
[16:30:37] <Tom_itx> we're getting a new one soon
[16:31:50] <Tom_itx> nothing like lax, houston, atlanta etc
[16:32:04] <ssi> ICT = midcontinent
[16:32:10] <Tom_itx> yes
[16:32:17] <ssi> it's not entirely arbitrary ;)
[16:32:31] <CaptHindsight> fares jumped 90% since i last checked
[16:32:45] <Tom_itx> not surprising
[16:32:56] <Tom_itx> what gets me is all the bagage charges
[16:32:58] <ssi> yea they're high now
[16:33:02] <ssi> last time I looked it was $300
[16:33:05] <ssi> now it's $563 :(
[16:33:12] <Tom_itx> that's how it is
[16:33:13] <ssi> for that money I'll burn 100LL
[16:33:17] <ssi> but I can't go anyway
[16:33:19] <ssi> I have to go to florida
[16:33:56] <CaptHindsight> 1500 mi RT for me
[16:34:06] <Tom_itx> there may still be one or two that give you the first bag
[16:34:07] <ssi> where you coming from?
[16:34:10] <DJ9DJ> gn8
[16:34:18] <CaptHindsight> near Chicago
[16:34:31] <ssi> 688.2 nautical miles WNW
[16:34:33] <ssi> about the same for me
[16:34:46] <ssi> 1582 statute miles round trip
[16:36:08] <ssi> only 509nm from ORD to ICT
[16:36:30] <Tom_itx> orlando?
[16:36:39] <Xfriend> andypugh: now I can see the machine working
[16:36:42] <ssi> chicago
[16:36:59] <CaptHindsight> google maps directions has it over 700mi
[16:37:21] <ssi> 509 nautical miles great circle distance
[16:37:23] <andypugh> Xfriend: You should probably check the scale now. Program a 1" / 50mm move and see if it is accurate.
[16:37:44] <ssi> as the gps-equipped crow flies
[16:40:37] <CaptHindsight> Amtrak takes forever, it's about the same distance from Beijing to Nanjing and that train only takes 4 hours and costs $75
[16:41:15] <Tom_itx> they're talking about putting in a high speed train here
[16:41:47] <Tom_itx> the train station isn't in wichita anymore, about 25mi N in Newton
[16:42:47] <CaptHindsight> 11:45hrs by Amtrak
[16:43:14] <CaptHindsight> same as driving
[16:43:48] <ssi> I could do wichita in my cherokee in about 6 and ahalf hours one way
[16:44:06] <Tom_itx> an oddity i experienced yesterday, my pendant quit moving the axis for a bit but when i moved the axis using axis the pendant would start working again
[16:44:09] <Tom_itx> any thoughts?
[16:44:12] <ssi> but it'd cost me $800 or more
[16:44:14] <ssi> round trip
[16:44:17] <ssi> just in fuel :?
[16:44:41] <CaptHindsight> need some higher gears
[16:44:43] <Tom_itx> 7i43 7i47 for boards
[16:44:55] <ssi> no gears
[16:44:59] <ssi> that's part of the problem... it's a one speed
[16:45:02] <ssi> :)
[16:45:29] <CaptHindsight> 4k rpm at 55mph?
[16:45:35] <ssi> 2700rpm at 140mph
[16:47:26] <ssi> there's also the problem that I have to finish some work on it before I can take it anywhere
[16:47:30] <CaptHindsight> never used a pendant with those
[16:47:33] <ssi> and I'll be in florida next weekend
[16:47:43] <ssi> sucks cause I really wanted to go to wichita
[16:47:45] <ssi> but family comes first :/
[16:51:26] <JT-Shop> I'm going to be gone most of this week to the smokey mtns
[16:51:43] <Tom_itx> didn't get enough the first time?
[16:52:31] <JT-Shop> didn't get much the first time on I40
[16:53:02] <JT-Shop> I did see the exit sign to Maggie Valley
[16:53:04] <Tom_itx> it's usually the wee hrs of the morning by the time i hit there
[16:53:29] <Tom_itx> too busy lookin for truckers n deer to see much else
[16:54:40] <JT-Shop> yea, don't know which is more dangerous
[16:55:05] <Tom_itx> foggy slick roads
[16:55:09] <Tom_itx> at night
[16:55:13] <Tom_itx> i don't care for it much
[16:56:08] <Tom_itx> i should go try this cube code out
[16:58:29] <CaptHindsight> LIGHT JET, seats 5-7, hourly rate $2,100 - $2,800
[16:59:18] <CaptHindsight> turbo-prop is $1,500 - $1,900 /hr
[16:59:47] <CaptHindsight> whats the range on a jetpack?
[17:00:10] <Tom_itx> depends what mountain you jump from
[17:03:12] <ssi> only $1500/hr for a turboprop?
[17:03:19] <ssi> what is it, a pilatus PC12?
[17:05:02] <CaptHindsight> http://www.onesky.com/flightplanner/acclass.cfm
[17:05:14] <CaptHindsight> Beechcraft BE-200
[17:08:02] <ssi> $1500 for a kingair 200?
[17:08:04] <ssi> seems cheap
[17:09:12] <CaptHindsight> pretty sure it's free if it doesn't make it
[17:12:14] <ssi> probably not
[17:12:18] <ssi> I'm sure they get a cc impression up front :)
[18:24:15] <CaptHindsight> pcw_home: how many 6i65's can you use with the 6i68 + 3x20? 6?
[18:24:49] <ssi> looks like it does
[18:24:50] <CaptHindsight> sorry 7i65's with the 6i68 + 3x20
[18:26:45] <Xfriend> CNC 3040T <<< who have one of this ?
[18:26:59] <Tom_itx> is peck drill and deep hole cycle the same in linuxcnc?
[18:27:17] <Tom_itx> one retracts a given distance, the other retracts clear out of the hole
[18:29:51] <Tom_itx> i think i see the issue, i had to change my post for the original sherline to G73 for peck instead of G83
[18:34:03] <Tom_itx> is Q the peck increment?
[18:34:09] <Tom_itx> and R the retract distance?
[18:46:37] <CaptHindsight> anyone ever battle with these and their development environment?
http://netduino.com/netduinoplus2/specs.htm STM32 cortex-m4
[19:03:51] <JT-Shop> Tom_itx: yes
[19:14:22] <Felix29> hey, does somebody here have a laser cutter by any chance?
[19:15:19] <JT-Shop> need to borrow one?
[19:16:19] <Felix29> well, i'd need some parts cut from melamine
[19:16:50] <Felix29> so if there's somebody or a hackerspace who has one
[19:17:00] <Felix29> i'd be happy to pay reasonably well for it
[19:18:06] <JT-Shop> can't think of anyone off hand that has a laser cutter, Jymmm has a laser engraver I think...
[19:18:39] <JT-Shop> if you live in any kind of city I'm sure there are some near you
[19:19:38] <Felix29> yeah, not really a city
[19:19:42] <Felix29> close to chicago though
[19:20:51] <JT-Shop> chicago laser cutter gets tons of hits on google
[19:22:15] <Felix29> yeah, i might just do that
[19:22:27] <Felix29> i figured giving beermoney to a hackerspace is better
[19:22:39] <Felix29> but worst case, i'll just contract it out to a small company
[19:22:46] <JT-Shop> laser cutters are not cheap to purchase
[19:23:11] <JT-Shop> why laser and not water jet on melamine?
[19:23:16] <JT-Shop> just wondering
[19:23:48] <Felix29> i think laser cutters are more likely to be in a hackerspace
[19:24:04] <Felix29> so there's no preference, but i think finding a lasercutter is more likely
[19:41:25] <Tom_itx> how do you run from line?
[19:41:38] <Tom_itx> if you want to start at a tool change in the middle of a file
[20:03:44] <Tom_shop> what would cause a program to stop in the middle of a tool path and request the next tool before it is finished cutting the first one?
[20:04:07] <Tom_shop> i've been getting odd errors like this the last couple days
[20:04:25] <Tom_shop> ubuntu 8.04 lcnc 2.5.2
[20:41:00] <atom1> can't do that (EMC_TASK_PLAN_RUN) in manual mode is the error i get when it paused in mid program
[21:49:25] <CaptHindsight> these are nice
http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,892,893&Prod=CHIPKIT-UNO32
[21:49:50] <CaptHindsight> 1/2 the price of Arduino but with 32b PIC at 80MHz
