[00:11:00] <mikegg> evening fellas
[00:12:29] <andypugh> Morning!
[00:13:45] <nicko> good day to you
[00:17:30] <mikegg> andy, i got my hands on a 5i20. Starting to work on config files for the 7i39
[00:19:51] <mikegg> where is the page on linuxcnc.org that breaks down all the hostmot2 firmwares?
[00:20:01] <mikegg> I've been hunting for days...
[00:20:25] <mikegg> I thought there was a chart or something
[00:21:28] <mikegg> ahah
[00:21:33] <mikegg> I found it\
[00:22:01] <Tom_itx> were?
[00:22:04] <Tom_itx> where?
[00:22:28] <mikegg> http://linuxcnc.org/docs/html/drivers_hostmot2.html#r1_11
[00:27:05] <mikegg> I wonder which firmware I should be using? SVTP6_7I39?
[00:27:34] <mikegg> or TPEN6_6
[00:27:59] <andypugh> the 7i39 one
[00:28:53] <andypugh> mikegg: http://www.bodgesoc.org/3PPWMTest.zip
[00:30:23] <andypugh> But: That predates the bldc component, so has two alternative HAL files for index-sinusoidal and Hall trapezoidal. with the combined component you start Hall and swap to sinusoidal on the first hall edge.
[00:30:41] <mikegg> awesome

[00:32:48] <andypugh> Those are the HAL files from http://www.youtube.com/watch?v=47y6RgAK--8 (need sound, really)

[00:36:24] <mikegg> wanted to watch it on the laptop with sound!
[00:37:20] <mikegg> that was the laziest way I could think of to get the link on the other computer
[00:37:44] <andypugh> Laziness is what got us to CNC in the first place

[03:00:18] <andypugh> <very late reply> mikegg Yes, it does all that bldc_hall and bldc_sine did, but better, and more besides.
[03:01:34] <mikegg> cool. Progress is going good. I've got the halls and the encoder wired up for the X-axis
[03:02:46] <andypugh> One of its best tricks (that as far as I know nobody has used yet) is to take a Hall pattern from a motor and convert it to a completely different one for a different manufacturers drive.

[03:43:37] <pcw_home> If you want to use it with the 7I39, probably need a bit file made
[03:44:57] -!- elmo40 has quit [Quit: Leaving.]
[03:45:56] <pcw_home> TPEN6_6.BIT might be right but theres no .PIN file for it so dont know for sure, You could load it and look at the pin list in dmesg
[03:47:04] <mikegg> hmm
[03:47:14] <mikegg> i've got the dmesg, hold on, I'll post it
[03:48:51] <mikegg> http://pastebin.com/70jFDk1w
[03:50:02] <mikegg> what does the .PIN file do?
[03:55:00] <pcw_home> Yes looks like it matches the 7I39
[03:55:02] <pcw_home> Pin files are just pinout documentation files
[03:55:09] <mikegg> uh-oh. just noticed theres no step gen stuff in there
[03:55:32] <mikegg> so far, so good. It's reading the encoder and the halls
[03:55:44] <pcw_home> Yes it a 6 axis 7I39 config
[03:58:33] Tech_Talk is now known as Birdman3131
[03:58:54] <mikegg> I gotta learn how to write that stuff myself
[03:59:07] <mikegg> I downloaded the ISE v13.2 or something
[03:59:12] <mikegg> installed it on windows
[03:59:37] <mikegg> I thought I saw a .ISE extension in one of the firmware directories
[03:59:43] <mikegg> is that a package or something?
[04:00:15] <pcw_home> .ise is probably a project file or some such
[04:00:29] <mikegg> am I better off with 9.2? I couldn't figure out how to install that
[04:00:40] <mikegg> kept asking for a libstd++5.so or something
[04:01:43] <pcw_home> 13.2 wont support Spartan2 (I think 10 is the latest that supports Spartan2)
[04:02:31] <pcw_home> I have 9.2 (for most things) and 13.something (for Spartan 6)

[10:45:47] <ktchk> The problem is I can see the right bottom on screen
[10:46:28] <ktchk> sorry can not
[10:46:38] <jthornton> did you move the status bar from the bottom of your desktop?

[10:58:16] <jthornton> what version of EMC are you running
[10:58:35] <ktchk> 2.4.6
[10:59:27] <jthornton> must be something with the touch screen, I changed this monitor to 800x600 and moved the status bar and had full view of the wizard
[11:00:33] <ktchk> no the touch screen is not working ubuntu can not drive the controller coming with thw pos
[11:01:14] <ktchk> The stepconf wizard fouth screen
[11:01:50] <jthornton> I can try again in a couple of minutes

[11:13:19] <jthornton> I just changed my 10.04 to 800x600 but can't move the status bar like I did on this 8.04 machine
[11:14:19] <ktchk> 8.04 can move the lower part?
[11:15:03] <jthornton> I got it to move and also auto hide menu bar but the basic machine information page is still too big

[11:15:31] <ktchk> hat
[11:16:09] <jthornton> that may have been fixed but not released yet... just checking now
[11:16:39] <ktchk> That I have found it the first time working with emc, then I change the hardware, now it come back again.

[11:24:42] <ktchk> It did not replace the stepconf wizard on the manual.
[11:25:23] <maximilian_h> can somebody please tell me if I can the current feed rate in the hal layer ? I'd like to have the value of the F word
[11:25:47] <jthornton> maximilian_h: what version of EMC?
[11:26:00] <maximilian_h> 2.3.2 or 2.4.6
[11:26:29] <maximilian_h> currently I have 2.3.2 on this specific machine, but I could update
[11:26:30] <jthornton> I think that is only available in the upcoming 2.5 as I use that myself

[11:31:24] <maximilian_h> not available I mean
[11:31:59] <jthornton> you could check and see if it is there
[11:32:06] <ktchk> jthornton: thanks I will go back to the 800x600 machine now, bye
[11:32:38] <jthornton> ok, seems like that page needs some fixing to fit
[11:33:05] <maximilian_h> alright I will check if it's there on 2.4.6
[11:33:06] -!- ktchk [ktchk!~eddie6929@n219073071198.netvigator.com] has parted #emc
[11:33:14] <maximilian_h> else I'd have to use 2.5
[11:33:25] <maximilian_h> what is the name of the 2.5 branch that you use ?
[11:33:53] <jthornton> v2.5_branch
[11:34:09] <maximilian_h> that has gladevcp too in it, doesn't it ?
[11:34:17] <jthornton> yep
[11:35:04] <maximilian_h> alright, then maybe it's time for a weekend of fun with emc2 ...
[11:35:18] <jthornton> lol
[11:35:32] <automata> actually it is not really that hard to get emc compiled and working from git...
[11:35:40] <maximilian_h> don't laugh, I am *really' serious
[11:36:07] <maximilian_h> yes I know, but when upgrading a machine you always run into new challenges
[11:36:13] <automata> I installed from the lucid CD and did a git pull and had emc2-dev compiled in a few hours
[11:36:14] <jthornton> maximilian_h: you know where the wiki page is that explains all that?
[11:37:05] <jthornton> also note the changes from 2.3 to 2.5 there is a couple of things that must be changed in your config
[11:37:06] <maximilian_h> yes, if you mean the stuff in the wiki page that is referenced from the web site and I still have my notes from last time too
[11:37:07] <automata> that is including the time it takes to download all the dependencies for compiling emc2-dev
[11:37:22] <jthornton> yes and the changes page
[11:37:29] <maximilian_h> ok
[11:37:57] <maximilian_h> i'll just tried full speed ahead and cry out loud when I need some help i guess

[12:40:32] <jthornton> that one was $250 it is quite small
[12:40:42] <jthornton> make a barrel stove
[12:41:09] <archivist> I have cut a couple of gas bottles ready

[12:45:36] <jthornton> my stove didn't come with a grate, instructions said line bottom and sides with firebrick lol. I had to purchase the grate seperate.

[12:47:24] <archivist> odd considering one has to get air to the underside
[12:47:57] <archivist> depends on burn rate you want too though
[12:50:04] <jthornton> that is the way they do the barrel stoves too with firebrick or just leave a few inches of ash in the bottom

[18:57:59] <Loetmichel> i worket about 10 years for a Stage rental company...
[18:58:27] <Loetmichel> you get used to "get the job done" even with missing tools
[19:02:08] <Loetmichel> luckyly i am not afraid of heights, so i can get up a rope ladder to a lighting rig suspended by 2 steel cables and resolder the damn cpu of the moving light ;-)
[19:03:26] <JT-Shop> Danimal_garage: 4 or 5" I forget
[19:03:32] <Loetmichel> ... swinging about 12m above the concrete floor, the mouth full of screws from the moving light and solder in one hand and the butane powered soldering iron in the other ;-)
[19:06:50] <archivist> Loetmichel, one should never tempt me with a ladder :), picnic up a chimney is fun, good view

[19:31:54] <Jymmm> Dumb question... On a small portable dust collector... If I reduce the exhaust opening from 4" to (let's say) 2.5", what is that changing? CFM or SP ? And isn't one inverse to the other?
[19:32:18] <archivist> the wooden steps cling to the inner side with nothing to support on the other as it winds up, with vertical standpipes in the middle
[19:32:54] <Danimal_garage> JT-Shop: i've been pricing land and steel buildings
[19:33:44] <JT-Shop> expanding Dan?
[19:34:01] <Danimal_garage> more like moving
[19:34:13] <Danimal_garage> the shop anyways
[19:34:32] <JT-Shop> Jymmm: the current draw will decrease as you unload the motor
[19:34:44] <JT-Shop> neighbors complaining about the mice?
[19:34:49] <Danimal_garage> i'd like to get an acre or so somewhere
[19:34:50] <archivist> Jymmm, measure, maybe the fan just increases the exit velocity
[19:34:53] <Danimal_garage> haha no
[19:35:08] <Jymmm> JT-Shop: So, the CFM will decrease?
[19:35:45] <archivist> the neighbours cats come for the mice here :)
[19:36:11] <Jymmm> archivist: I don't have anything to measure CFM nor SP with.
[19:36:18] <Danimal_garage> do the Chineese food restaurant owners go there for the cats?
[19:36:40] <archivist> no cat population seems constant
[19:36:50] <Danimal_garage> hmm, untapped market
[19:36:51] <archivist> fat though
[19:37:02] <Danimal_garage> pefect, not gamey
[19:37:23] <Danimal_garage> great for General Tso's Chicken
[19:37:24] * Jymmm lol @ Danimal_garage
[19:37:28] <JT-Shop> Jymmm: sure unless you have a forced displacement pump then that changes everything
[19:37:54] <JT-Shop> Danimal_garage: yep 4 bolt axles
[19:37:59] <Jymmm> JT-Shop: It's just a HF Dust Collector, nothing fancy at all.
[19:37:59] <archivist> Jymmm, make a flap meter measure flow/pressure
[19:38:15] <Jymmm> archivist: O_o
[19:38:35] <Danimal_garage> what's a good use for a pump that flows 45ghp at 150psi?
[19:38:52] <archivist> scrap metal?
[19:38:53] <Jymmm> Danimal_garage: gph?
[19:39:06] <Danimal_garage> gallons per hour

[19:39:24] <Jymmm> Danimal_garage: PRessure washer?
[19:39:40] <Danimal_garage> not sure if that's enough gph for that
[19:39:55] <JT-Shop> pool filter pump?

[19:40:11] <Jymmm> Danimal_garage: Cat Water Cannon?
[19:40:14] <archivist> boiler filling
[19:40:29] <Danimal_garage> hmm
[19:40:45] <JT-Shop> hot water circulation pump?
[19:40:49] <Danimal_garage> maybe
[19:40:57] <Jymmm> JT-Shop: 150PSI YEOW!
[19:41:21] <Danimal_garage> it has a piston and valves instead of a turbine rotor
[19:41:38] <Jymmm> Ok, so what fluid needs high pressure, but low(er) flow?
[19:41:46] <archivist> we had a boiler filling crisis at the pumping station last weekend
[19:41:50] <Danimal_garage> thats what i was wondering
[19:42:32] <Jymmm> Danimal_garage: Is it a water pump, or for things like oil, etc
[19:42:33] <archivist> we could use something like that hidden away
[19:42:40] <Danimal_garage> dont know
[19:44:27] <Jymmm> OH, I know.... Pesticide/herbicide dispensing, like in fields on the back of a tractor or part of the irrigation system
[19:45:38] <Jymmm> where they need a wide spray pattern, but low flow
[19:46:16] <Jymmm> btw it looks like pressure washers are around 2500PSI @ 3GPM

[23:32:01] <Loetmichel> (yes, thats me ;-)
[23:32:40] <andypugh> Yes, quite a lot like that, but sharper.
[23:33:01] <andypugh> And I want your workshop.
[23:33:20] <Loetmichel> isnt/wasnt mine
[23:33:38] <Loetmichel> was the shop of my employer
[23:33:58] <andypugh> Ah.
[23:34:18] <Loetmichel> it says "loetmichels workwebcam" on the bottom
[23:34:20] <andypugh> I wonder if my employer has a workshop?
[23:35:06] <Loetmichel> you could have watched me working in that time.
[23:35:22] <andypugh> By which I mean, does Bill Ford have a home workshop full of cars, I wonder.
[23:35:33] <Loetmichel> now i work for a company which makes military computers, webcam-> not so good ;-)

[23:36:41] <Loetmichel> the redshirt was my boss ;-)
[23:42:36] <mikegg> andypugh: If I have an encoder, do I even need to hook up the Hall sensors?
[23:42:37] <Connor> Tom_itx: Compound Miter saw, and no, it didn't grab.
[23:43:25] <andypugh> mikegg: No. But if it isn't an absolute encoder, I think it is best to

[23:44:45] <mikegg> ok, is there a way to figure out how many poles my servos have?
[23:44:55] <andypugh> It is hard to start a brushless motor without knowing the rotor position. the bldc component has a way of doing it, but it isn't ideal.
[23:45:36] <andypugh> Apply a small voltage from a PSU to two windings, and see how many notches per rev.

[23:46:23] <andypugh> (ie, go for a few hundre mA and turn the shaft by hand
[23:47:43] <mikegg> ah, ok
[23:48:13] <mikegg> when you say small, I'm thinking like 5 VDC
[23:48:45] <andypugh> if you have a current-controlled supply that would be best
[23:49:00] <mikegg> negative
[23:49:34] <mikegg> hmm maybe at work
[23:49:35] <andypugh> And yes, it will be a few volts. Some small fraction of rated volts
[23:49:39] <Loetmichel> a 12V power supply and a car headlight or better blinker lamp in series will do also
