[00:15:28] <cncjerry> anybody home?
[00:15:49] <cncjerry> I installed the latest and I am being prompted for an upgrade.
[00:16:03] <cncjerry> bunch of security things.
[00:16:29] <cncjerry> wondering if I should leave well enough alone or do the automatic software upgrade?
[00:17:55] <cncjerry> ?
[00:29:03] <cncjerry> it's me again.
[00:29:12] <cncjerry> quick question if anyone is awake.
[00:29:41] <cncjerry> is is possible to override the error that won't allow you to issue commands until everything is homed?
[01:43:54] <Jymmm> Crap, one of my sharpening stones is cracked
[01:59:36] <DJ9DJ> moin
[02:01:59] <foo303> moin moin
[02:02:22] <foo303> has anyone had to deal with a large servo of an old machine without a datasheet? If so, how do you go about the wiring?
[02:02:28] <foo303> I copied what's written on that motor
[02:02:32] <foo303> http://pastebin.com/N8RRYTms
[02:02:38] <foo303> but I have no further info on that motor
[02:02:49] <foo303> I believe it's 6 wires, iirc
[02:14:39] <archivist> foo303, have you tried emailing the makers
[02:14:58] <foo303> afaik, the machine is 30 years old
[02:15:15] <foo303> so the motor is at least that old and as you can tell, no contact info whatsoever hehe
[02:16:06] <foo303> from what I was told, it was owned by a french company that was told to leave for not paying the rent, so that's why all the connections between the control box and the motors/encoders are chopped off
[02:16:51] <foo303> oh well, so it seems like if worse comes to worst, I'll just get a new motor and drive, but I have no idea of what torque would be needed to move that heavy axel
[02:17:05] <foo303> can you tell from the data I pasted such a thing, archivist?
[02:17:45] <archivist> you seem to have enough info to find a replacement
[02:18:40] <archivist> although Nmax has no radius to make the unit usable
[02:19:34] <foo303> hmm, so what's Nmax?
[02:19:43] <foo303> is that the maximum force?
[02:19:54] <foo303> (might have sounded stupid :p)
[02:19:58] <archivist> newton at some radius
[02:20:06] <archivist> torque
[02:20:23] <foo303> oh, so Nmax is torque.. with no unit. god damn.
[02:21:47] <archivist> usually NM for newton at a metre, smaller motors will be at an inch or a centimetre
[02:23:16] <archivist> the tacho part and also the line 20Volt/1000RPM are a voltage generated for velocity feedback
[02:23:50] <foo303> I might just pay a visit with an arduino and a multimeter, to try to use the current drive(if I could know the control voltage for it and/or firut out how to wire it haha)
[02:24:03] <archivist> this is in addition to the encoder feedback
[02:24:07] <foo303> so at 20Volt I can get 1000 RPM
[02:24:18] <archivist> no it is an output
[02:24:23] <foo303> oh
[02:24:35] <foo303> so its power supply, then, what is it? :D
[02:24:46] <archivist> spin it at a 1000 and look for the 20
[02:25:07] <archivist> the tacho part and also the line 20Volt/1000RPM are a voltage generated for velocity feedback
[02:25:08] <foo303> oh, so I can test the polarity of the power supply by testing while spinning it manually!?
[02:25:20] <archivist> you are confused
[02:25:59] <foo303> admittedly :p
[02:26:13] <archivist> there is a tacho generator in the motor to tell the control how fast and what direction the motor is spinning
[02:26:42] <foo303> okay, so some of those wires are probably to get that feedback
[02:27:05] <foo303> (or am I still confused about this part?)
[02:27:36] <foo303> I'll check out what a tacho generator means
[02:27:40] <foo303> sec.
[02:28:55] <foo303> oh okay, so it's like an encoder
[02:29:36] <foo303> that will give out 20 volt per 1000 rpm of speed
[02:29:51] <foo303> so if it's at 250 rpm, I should expect to read 5V out of it
[02:30:19] <archivist> yes
[02:30:39] <foo303> and so, if I rotate manually and test, I should be able to determine the polarity of that tacho generator
[02:30:45] <foo303> that's 2 wires down, 4 to go
[02:30:47] <foo303> :D
[02:30:53] <foo303> 2 should be power, that's for sure
[02:31:12] <archivist> you will not have separate power
[02:31:19] <archivist> normally
[02:31:48] <foo303> what do you mean by separate power?
[02:31:50] <archivist> may have separate field and armature for a dc motor
[02:32:11] <archivist> so you can wire series or parallel
[02:33:03] <archivist> as yet we are guessing the motor type, are all wires thick/same diameter
[02:33:48] <archivist> is there a separate cable from the encoder, does the encoder bundle include the tacho wires
[02:35:04] <foo303> I don't remember that for sure
[02:35:18] <foo303> but I was told to look for thick wires, as those will be the power ones
[02:35:43] <foo303> there was an actual 12V encoder from esa right next to it, but I'll go today to do the tests you suggested
[02:35:50] <foo303> there is a brake unit however
[02:36:01] <foo303> and that's active low, so I need to figure out its polarity first
[02:36:28] <archivist> 2 wires for tacho, 2 dc servo 2 brake
[02:36:28] <foo303> in the control cabinet, there's a box with "Allen Bradely" on it
[02:36:44] <foo303> indeed, that's what I think too
[02:37:26] <foo303> but if I mess up while connecting the servo, the servo is no more :p
[02:37:31] <archivist> allen bradley do make various things getting the part number off that and looking it up would help
[02:37:41] <foo303> probably the same with the break
[02:37:53] <archivist> the servo drive may die not the motor
[02:37:53] <foo303> brake*
[02:38:30] <foo303> oh really? hmm. okay, I'll go in a bit, get some photos and try a few things
[02:38:40] <cncbasher> foo303: sounds a familiar sem 140v , 2 heavey thick wires for dc power with 2 for tacho ,2 for brake , should perhaps have a second harness plug for an encoder or resolver on the rear
[02:38:41] <foo303> I'll keep you updated if you're interested, with pictures hopefully
[02:38:47] <archivist> I expect it to be robust and you can check what the wires do easily without damage
[02:39:06] <cncbasher> foo303: post some pics would help
[02:39:26] <foo303> yup, I will.
[02:39:35] <foo303> I'll stay joined. see you all very soon
[02:39:38] <foo303> :>
[02:39:38] <archivist> we are all guessing till we see pics, make sure well in focus :)
[02:40:32] <cncbasher> i'll guess it's a SEM / Baldor motor
[02:41:07] <cncbasher> especialy with an Allen Bradley controller
[02:44:19] <Valen> !seen andypugh
[02:44:20] <the_wench> last seen in 2013-02-11 23:36:38GMT 08:54:46 ago, saying Quit: andypugh
[02:44:28] <Valen> dammit why cant I run into that guy
[02:45:32] <archivist> usually on evening our time :)
[03:37:14] <Loetmichel> mornin'
[04:51:09] <mrsun> yeah how fun it is to borrow stuff, a friend said he had a drill that i needed so i went over and drilled, only problem was that the drill looked a bit strange to me, oh well he told me that he had and it was the only one there, it was carbide tipped, well 2 holes and voila .. chipped
[04:51:18] <mrsun> always fun to use other peoples stuff :/
[04:51:40] <Thetawaves> http://www.youtube.com/watch?v=5Z_Eg17rLlQ
[04:51:52] <mrsun> and the spiral flutes didnt look right either
[04:51:55] <mrsun> to low angle
[04:51:58] <mrsun> or what its called
[04:56:56] <mrsun> aparently not recommended to drill steel with
[05:15:10] <p0g0> sounds like a ceramic drill, for concrete etc.
[05:17:33] <mrsun> p0g0, aparently its for softer metals etc also
[05:17:36] <mrsun> from what i can find
[05:17:40] <mrsun> copper
[05:17:41] <mrsun> alu
[05:17:48] <mrsun> and cast iron
[05:17:58] <mrsun> but not for ordenary soft hot rolled steel :P
[05:18:01] <p0g0> not a ceramic bit then, I'd guess
[05:18:36] <mrsun> Features heavy-duty construction and heat treated body for optimum wear resistance and support of the carbide tip. Used in the production of cast iron, non ferrous metals, and many composite materials such as hard rubber or copper alloys. NOT recommended for drilling steel
[05:19:16] <mrsun> is what i find of drills that looks almost similiar
[05:19:24] <p0g0> those tend to be a dual flute with a pair of carbide flanges at the top, often galvanized. Good for brick, concrete, and it won't kill them to drill wood.
[05:19:31] <mrsun> the ones for ceramic most often from what i can see does have a bigger drilling head then body
[05:19:41] <mrsun> this one is like a twist drill with less twist and carbide inserts
[05:19:45] <mrsun> or not inserts
[05:19:51] <mrsun> brazed in place
[05:20:09] <p0g0> probably silver soldered, but maybe brazed...
[05:20:28] <mrsun> ye whatever its sitting there with it wasnt good for drilling steel atleast :P
[05:20:37] <mrsun> hopefully its grindable
[05:20:48] <mrsun> else i can see another couple of bucks flying away from me :P
[05:21:10] <p0g0> the carbide migh grind with great care- you can heat them too much and break them from the solder/braze
[05:21:29] <p0g0> or kill the temper
[05:21:39] <mrsun> ye :/
[05:21:56] <mrsun> anyhow, now im even more motivated to buy me an assortment of drills
[05:22:00] <mrsun> i HATE borrowing stuff
[05:22:02] <mrsun> everything breaks
[05:22:16] <mrsun> broke a die grinder for this guy also .. cost me $20 in replacement parts ... :/
[05:23:14] <p0g0> if you want an interesting exercise, learn to sharpen the twist drills.
[05:23:44] <mrsun> p0g0, im learning that atm, started sharpening my own as i have alot of dull drills :P
[05:24:03] <p0g0> don't we all...
[05:24:03] <mrsun> so far with "great" success :P
[05:24:09] <mrsun> 11mm drill drilled 11.5mm :P
[05:24:14] <mrsun> but cut like cutter :P
[05:24:50] <mrsun> but angles was off as i did it just by eye .. found a angle guage now so i can see what angle i get and how long the sides are =)
[05:25:39] <p0g0> centering the faces, getting the center to edge slope and the toe to heel slope right is not trivial
[05:26:18] <mrsun> p0g0, well they cut alot better than when they are dull and chipped no matter how i grind them :P
[05:26:30] <p0g0> if you get good, you can tweak those for the hardness of the material and the speed you are cutting
[05:26:53] <p0g0> you can get the heel too high and they won't cut at all...
[05:27:12] <p0g0> just spin on the high spot.
[05:47:17] <ArcEye> mhaberler - sent reply email re latency
[05:47:28] <mhaberler> ah!
[05:47:50] <ArcEye> basically the cpu-hog effect is very strong
[05:48:24] <mhaberler> odd; did you read yesterday' session with skunkworks?
[05:50:38] <ArcEye> I read the link to the irc conversation, I could replicate some of that
[05:51:03] <ArcEye> I then tried running dohell whilst running latency-test
[05:51:09] <mhaberler> well at least that wasnt all bogus then
[05:51:43] <ArcEye> that kept latency down whilst it was running but it jumped up afterwards
[05:51:47] <mhaberler> what cpu/board was that again? any dmesg?
[05:52:07] <ArcEye> So I tried a cpu-hog and it did exactly the same
[05:52:27] <mhaberler> that's very valuable, we're collecting facts for the xeno list
[05:52:50] <ArcEye> Intel quad core 2.3GHz, all the machine specs are in the first zip I sent john
[05:53:03] <mhaberler> ArcEye == Schooner?
[05:53:47] <ArcEye> Yes, when I joined the list it grabbed my email as nickname and I couldn't be bothered to change it
[05:54:01] <mhaberler> jeeesh, we need an alias resolver..
[05:54:02] <ArcEye> I am ArcEye on the forum
[05:54:23] <ArcEye> Just trying to preserve my mystery!
[05:54:24] <mhaberler> figured that, but the == schooner == mick part wasnt clear
[05:54:47] <mhaberler> just because you're paranoid, that doesnt say they are _not_ after you
[05:55:25] <mhaberler> ok, so then this is not AMD-related, which saves me reading errata
[05:55:50] <ArcEye> Anyway I have some tests to do on a home brew xenomai kernel, I turned off all the power management, virtualisation etc etc
[05:56:03] <mhaberler> any difference?
[05:56:24] <mhaberler> ah I see, not yet then
[05:56:54] <ArcEye> Don't know yet, but if it was rtai it would make a difference, I could not understand why they were not disabled
[05:57:32] <mhaberler> well I'm very curious what you find out
[05:58:18] <ArcEye> Once done I will re-visit the P4, that should be a lot better than it is, but cpu-hog should not be the answer, it is single core
[05:58:43] <mhaberler> yes, that was completely off the bat
[05:59:03] <ArcEye> I will try building a non SMP kernel for it and see where that goes
[05:59:31] <mhaberler> is that P4 a SP?
[05:59:43] <mhaberler> single CPU I mean?
[05:59:50] <ArcEye> Yes
[05:59:53] <mhaberler> Gilles indicated this might make sense
[06:00:21] <ArcEye> It would only ever run properly on non SMP 8.04
[06:00:33] <ArcEye> But good latency sub 9K
[06:00:34] <mhaberler> make sure you run the regression tests on the UP kernel
[06:00:55] <mhaberler> I ve never done so (linuxcnc runtests that is)
[06:01:03] <ArcEye> UP = uni processor?
[06:01:07] <mhaberler> yes
[06:01:25] <ArcEye> will do, off now spk later
[06:01:35] <mhaberler> well I think we're up to something at least. Thanks!
[06:13:50] <skunkworks> Yay - looks like I am not crazy
[06:36:56] <jthornton> get reset --hard No command 'get' found, did you mean:
[06:58:27] <skunkworks> bbl
[07:34:10] <r00t4rd3d> eww Android 4.2.2 update is rolling out
[07:35:35] <skunkworks> is that bad?
[07:35:59] <r00t4rd3d> For people not a Google device
[07:36:49] <r00t4rd3d> Unless the word Nexus is in your devices name, you wont be getting it anytime toon
[07:36:52] <r00t4rd3d> soon*
[09:41:35] <JesusAlos> hi
[09:41:53] <JesusAlos> enybody know about the 7i77 mesanet card?
[09:42:25] <JesusAlos> I want to put enable output 0 to 1
[09:42:28] <JesusAlos> but I can't
[10:12:40] <bigvalen> Noob question; I've managed to build a working mill, but I've no Z probe. Has anyone seen ideas on how to make up some sort of capacitive (or better) Z probe that can be hooked up into LinuxCNC ? (My mill has spare a e-stop and a probe pin I could use)
[10:14:47] <cradek> lots of people have made renishaw clones (the 3 sticks on 6 balls setup)
[10:15:24] <cradek> I think it's not really that hard a machining project. I bet you could find some build threads.
[10:22:37] <bigvalen> As in, a clone of something like http://www.renishaw.com/en/tp200--6671 ?
[10:23:36] <cradek> bigvalen: google DIY touch probe
[10:23:41] <cradek> that seems to be the secret phrase
[10:24:14] <cradek> http://www.vinland.com/Images/20080823_140825_w.jpg
[10:24:23] <bigvalen> Cool, more complex than I thought, but it'll do :)
[10:24:36] <tjb1> complex?
[10:24:56] <cradek> if you only need to probe Z, you could use a simpler design that's just a switch. but for a general purpose probe this is a good design
[10:25:08] <bigvalen> I'm new. I was imagineing something ghetto like a spring wire that'd conduct when it touched metal :)
[10:25:09] <cradek> as you can probe hole diameter/center, and edges too
[10:25:40] <skunkworks> I bet softlimits in mach suck... I have never ran the machine into the hard limits after homing.
[10:25:57] <bigvalen> (it's for something like http://phk.freebsd.dk/CncPcb/ )
[10:28:13] <cradek> that setup is clever
[10:28:26] <cradek> why did you decide not to do the probing like he does?
[10:30:44] <pcw_home> JesusAlos: Which enable? the 7I77 Drive enables are OPTOs that conduct when enabled and are open when disabled
[10:32:26] <pcw_home> (there is one logical enable for all axis except axis 5 which is independent)
[10:32:30] <archivist> pcw_home, he left, but...is he really asking about signal inversion
[10:32:42] <pcw_home> cannot be done
[10:32:55] <pcw_home> deliberately
[10:33:13] <pcw_home> switch off = disabled
[10:33:30] <archivist> I never know with his questions :)
[10:38:42] <pcw_home> Some silly drives have contact closure to disable but this is rare
[11:07:47] <Loetmichel> re @ home
[11:17:35] <cncjery> anybody home?
[11:18:00] <cncjery> is there a way to turnoff the 'cant issue gcode until homed' "feature"?
[11:18:08] <archivist> no, all in the pub
[11:18:16] <cncjery> was looking.
[11:18:57] <cncjery> also, I recently started received notices that there are upgrades (automatically checked, I believe) should I upgrade or keep vanilla ?
[11:19:12] <cncjery> security upgrades mostly
[11:19:31] <cncjery> the last time I let this thing do upgrades I ended-up with a mess
[11:21:51] <cncjery> ?
[11:25:25] <archivist> you need NO_FORCE_HOMING = 1
[11:25:44] <cncjery> where does that go?
[11:26:04] <cncjery> ini I guess, under where?
[11:26:04] <archivist> see http://www.linuxcnc.org/docs/devel/html/config/ini_config.html
[11:26:30] <cncjery> k, did you see my follow-up about auto system upgrades?
[11:27:24] <archivist> I tend to leave a working system working :)
[11:27:54] <cncjery> I should have done that with 2.3
[11:28:14] <cncjery> You might remember the mess I had a few months back from the upgrade.
[11:28:41] <cncjery> I am thinking about turning that nag off.
[11:28:46] <archivist> I dont remember
[11:29:47] <cncjery> one of the reasons I went from 2.3 to 2.x (latest -1) was that I have a little backlash set on my Z.
[11:30:28] <cncjery> on 2.3, sometimes right when I started to enter manual gcode, I would hear the backlash take-up.
[11:30:56] <cncjery> this was before I would load code. it did it also when I loaded code, before I was running it.
[11:31:08] <cncjery> almost like it was presetting the backlash for the first move.
[11:31:40] <cncjery> know anything about this?
[11:32:17] <cncjery> my code took the initial jog into consideration. so I would load code and it seems like it would reverse sometimes.

[12:08:51] <jdh> I've been fighting with an ancient GE/Fanuc Series6 PLC since I got in this morning :(
[12:09:12] <jthornton> is that the big brick ones?
[12:09:19] <jdh> it's big
[12:09:23] <jthornton> like the AD 305's
[12:09:39] <jdh> no clue what an AD 305 is
[12:10:04] <jdh> oh, that AD... nah, this thing is huge
[12:10:51] <jthornton> like the AB plc5 then a monster with 12" tall cards :)
[12:11:12] <jdh> yep
[12:11:18] <jthornton> yuck
[12:11:21] <jdh> 5 racks full of crards
[12:11:46] <jdh> and best of all, a big chunk of output bits that all come on by themselves
[12:12:08] <jthornton> yikes, that is not fun
[12:12:44] <jdh> nope. Kind of nifty though, the machine sits there and auto-cycles sort of.
[12:16:07] <andypugh> It may be borked
[12:37:09] <tjtr33> foo303 your data was a bit jumbled& out of order but here it is a bit more sorted out http://pastebin.com/vxQC4FiT
[12:51:13] <JesusAlos> hi
[12:53:42] <JesusAlos> andypugh: I can't put the enable to 1 in 7i77 card
[12:53:45] <pcw_home> JesusAlos: dont know if you saw this: Which enable? the 7I77 Drive enables are OPTOs that conduct when enabled
[12:53:47] <pcw_home> and are open when disabled (there is one logical enable for all axis except axis 5 which is independent)
[12:54:17] <JesusAlos> I need force manually
[12:54:42] <JesusAlos> by command like: setp hms_5i25....
[12:54:56] <pcw_home> Yep that will work
[12:55:02] <JesusAlos> I don't saw
[12:55:49] <JesusAlos> but I don't foun the pin name in hal configuration
[12:55:52] <pcw_home> The first thin to do is may yourself a pin list with halcmd show pins
[12:56:00] <pcw_home> make yourself
[12:56:30] <JesusAlos> yes I open the hal configuration, and see the 5i25 and 7i77 cards
[12:56:44] <JesusAlos> but don't found the Enable pin name
[12:56:58] <JesusAlos> of 6 axis
[12:57:07] <JesusAlos> you undestand me?
[12:57:29] <pcw_home> hm2_5i25.0.7i77.0.1.analogena is for axis 0..4
[12:58:00] <pcw_home> hm2_5i25.0.7i77.0.1.spinena is for axis 5 (reserved for spindle)
[12:58:29] <JesusAlos> ok
[12:58:31] <JesusAlos> wait+
[13:02:26] <JesusAlos> http://imagebin.org/246429
[13:03:11] <JesusAlos> there are only one enable
[13:03:20] <JesusAlos> and the command don't go
[13:03:57] <pcw_home> It shouldn't
[13:04:13] <JesusAlos> you see in image
[13:04:23] <pcw_home> Yes
[13:05:04] <pcw_home> Notice its already connected to x-enable
[13:05:52] <JesusAlos> and?
[13:06:09] <JesusAlos> where is the other 5 enable pins?
[13:06:24] <pcw_home> you cannot set it by hand unless its unconnected
[13:07:24] <pcw_home> there are 2 enables, analogena for analog channels 0..4 and spinena for channel 5
[13:09:29] <JesusAlos> I revised Pncconf wizard
[13:09:39] <JesusAlos> There are 3 axis enable
[13:09:47] <JesusAlos> X Y Z encoder
[13:10:15] <pcw_home> If you want to set the pin by hand you must unlink it (or comment out in HAL and reload linuxcnc)
[13:10:21] <JesusAlos> But there don't are the option of enable the enable pin for each encoder
[13:11:27] <JesusAlos> But there are 3 analog output in use, the other analog must be appears
[13:11:35] <pcw_home> there are no encoder enables (but there are analog out enables) There is only a common one for all axis
[13:11:37] <pcw_home> you can just connect this to x-enable as it is now
[13:14:16] <JesusAlos> http://imagebin.org/246430
[13:14:25] <JesusAlos> is correct the configuration?
[13:15:54] <Jymmm> ~~~ Ancient Greece Lego Antikythera Mechanism. http://www.wimp.com/legoantikythera/
[13:17:12] <pcw_home> I guess its ok, but I am not pncconf expert
[13:18:42] <Jymmm> ~~~ Salsa dog http://www.wimp.com/salsadog/
[13:19:00] <JesusAlos> I don't know why appear PWM if connector TB5 is analog output
[13:21:10] <pcw_home> Its holdover from older cards that have PWMGen in the FPGA pncconf just uses the PWMGen name
[13:22:58] <andypugh> JesusAlos: Despite the fact that LinuxCNC has a separate enable pin for each axis, they all get set and reset at the same time, so might as well be one pin.
[13:22:59] <JesusAlos> it's so only semantical question?
[13:23:30] <Jymmm> archivist: You would like the Ancient Greece thing
[13:23:38] <andypugh> What isn't clear is if you have also linked the x-enable _signal_ to the axis.0.amp-enable _pin_
[13:26:49] <pcw_home> I'm pretty sure it is (having looked at other pncconf created hal files)
[13:27:36] <JesusAlos> http://imagebin.org/246433
[13:27:42] <JesusAlos> yes is connected
[13:28:33] <JesusAlos> but I don't connected it consciously
[13:30:06] <pcw_home> pncconf connected it correctly
[13:32:24] <JesusAlos> setp hm2_5i25.0.7i77.0.1.analogena 0
[13:32:40] <JesusAlos> is bit type data
[13:33:12] <JesusAlos> so, it only is a bit, cant put: setp hm2_5i25.0.7i77.0.1.analogena1
[13:33:17] <JesusAlos> or setp hm2_5i25.0.7i77.0.1.analogena2
[13:33:43] <pcw_home> 1 or 0 are OK as are true and false
[13:34:08] <JesusAlos> yes, but system not recognized
[13:34:27] <pcw_home> there is no analogena1
[13:34:45] <pcw_home> there is only analogena and spinena
[13:35:02] <JesusAlos> and what is the pin name of 0,1,2,3,4,5 enable output?
[13:35:14] <pcw_home> they do not exist
[13:35:48] <cpresser_> JesusAlos: try 'halcmd show' to see all signals and pins available
[13:36:10] <JesusAlos> why? so, how force manually?
[13:36:31] <JesusAlos> cpresser: I use hal configurator and see all pins
[13:36:40] <JesusAlos> but not enable pins
[13:39:50] <pcw_home> you cannot force a pin manually unless you disconnect it from the signal that drives it
[13:41:20] <andypugh> JesusAlos: You can type "unlinkp hm2_5i25.0.7i77.0.1.analogena" then "setp hm2_5i25.0.7i77.0.1.analogena 1"
[13:41:38] <andypugh> But I suspect that isn't what you really want to do...
[13:41:57] <andypugh> Isn't the problem here just that you haven't pressed the "machine on" button?
[13:44:27] <pcw_home> I would be wary of enabling by hand (and verify that the drive enable actually works first)
[13:44:29] <pcw_home> and also consider that the first time turn on of a servo system is likely to cause a run away
[13:54:07] <JesusAlos> andypugh: yes if unlink can setp pin
[13:55:22] <andypugh> It shouldn't be necessary though, x-enable should be linked to axis.0.amp-enable, so the enable should come on whn you press the GUI button.
[13:56:21] <JesusAlos> enable of all 6 axis?
[13:57:10] <pcw_home> no just 5 (0..4)
[13:58:28] <JesusAlos> ok. I finally undestand it
[13:58:34] <JesusAlos> thank both
[13:59:05] <JesusAlos> other question. Can I connect a ralay betwin ENA0+ and ENA0-
[13:59:07] <JesusAlos> pins?
[13:59:24] <JesusAlos> a coil relay
[14:00:14] <pcw_home> You can drive a small relay with the ENA pins (and +24V for example) but why?
[14:00:55] <JesusAlos> My drive need a contact clean of voltage
[14:01:15] <pcw_home> the enables are isolated
[14:01:39] <JesusAlos> ok. I try it
[14:02:12] <pcw_home> they are effectively a polarized contact
[14:03:13] <JesusAlos> so, don't need relay?
[14:03:20] <pcw_home> so if you have enables that need a contact closure
[14:03:22] <pcw_home> they will work for that (making sure you have the polarity right)
[14:03:50] <pcw_home> and the drive enables dont need more than 50 mA
[14:04:02] <JesusAlos> ok
[14:10:55] <JesusAlos> unlinkp hm2_5i25.0.7i77.0.1.analogena
[14:10:58] <JesusAlos> then
[14:11:11] <JesusAlos> after
[14:11:12] <JesusAlos> setp hm2_5i25.0.7i77.0.1.analogena 1
[14:11:39] <JesusAlos> and ther no change betwin ENA0+ and ENA0- pins
[14:11:49] <JesusAlos> setp hm2_5i25.0.7i77.0.1.analogena 1
[14:11:52] <JesusAlos> setp hm2_5i25.0.7i77.0.1.analogena 0
[14:11:59] <JesusAlos> no voltage change
[14:12:18] <pcw_home> there is not expected to be any
[14:13:11] <JesusAlos> why?
[14:13:38] <pcw_home> the ENA+ and ENA- are the output of an Opto-coupler so basically a switch
[14:14:03] <JesusAlos> free of voltage
[14:14:05] <pcw_home> you will see a difference with an Ohmmeter
[14:14:06] <JesusAlos> ok
[14:14:14] <JesusAlos> ok
[14:14:37] <pcw_home> yes no voltage just like a polarized relay contact
[14:15:22] <JesusAlos> you're right
[14:15:30] <JesusAlos> it run
[14:19:40] <pcw_home> In general you _DONT_ want to do this manually as the enable are part of the shut-down-drives-on-ferror logic
[14:20:07] <JesusAlos> undestand
[14:20:28] <pcw_home> so having a safe ferror value and drive enable in LinuxCNCs control is a safety issue
[14:20:55] <pcw_home> (This in no way replaces ESTOP)
[14:22:01] <JesusAlos> I'm going to change the diaper to my 6 month babe
[14:22:16] <JesusAlos> and dine
[14:22:28] <JesusAlos> thank you very much
[14:22:33] <pcw_home> Glad its you!
[14:23:32] <pcw_home> and welcome
[14:26:49] <jdh> hmm... diapers and dining.
[14:33:13] <pcw_home> reverse sounds better
[14:33:45] <jdh> having the wife do it sounds better.
[14:34:23] <pcw_home> not to the wife
[14:34:45] <jdh> they don't mind.
[14:41:34] <micges> pcw_home: what was result of 9030w test?
[14:43:41] <pcw_home> Oleg got distracted. I'll check up on it in a bit
[14:44:16] <micges> thanks

[18:27:34] <gene77> 'squiet here tonight, everything must be working?
[18:29:30] <ReadError> wait till tomorrow ;)
[18:29:34] <ReadError> ill have 300 questions
[18:29:38] <JT-Shop> working too hard
[18:29:59] <gene77> What at John?
[18:30:43] <JT-Shop> log splitter, neighbors well, another neighbors throwing axe, real work in between...
[18:30:59] <JT-Shop> and a carpet cleaner lol
[18:32:38] <gene77> Me, I'm bored, watching my toy mill carve wrench flats on a BP nipple. Its a bit like drying paint, could use a new bit. Carpet Cleaner? Sound like something the DW threw at you :)
[18:33:14] <JT-Shop> neighbors son has a cleaning business, when things need welding he brings them to me
[18:33:27] <gene77> Ahh.

[18:38:10] <Tom_itx> :(
[18:38:20] <JT-Shop> for the photos?
[18:38:23] <Tom_itx> yup
[18:38:29] <JT-Shop> sucks
[18:39:24] <JT-Shop> http://imagebin.org/246468
[18:39:48] <JT-Shop> http://imagebin.org/246469
[18:39:50] <gene77> sucking info to sell. Suck isn't exactly the right word though.
[18:39:51] <JT-Shop> better?
[18:40:33] <Tom_itx> is that 1" backing plate?
[18:40:46] <Tom_itx> i'd still put a brace behind it
[18:41:21] <JT-Shop> yea, it is just leaning up against the beam atm
[18:41:39] <JT-Shop> 1" thick yes
[18:41:49] <Tom_itx> did you go with a 3 or 4" cyl?
[18:41:59] <JT-Shop> there is much more that goes on there lol
[18:42:06] <Tom_itx> i'm sure
[18:42:07] <JT-Shop> 4" x 24" Lion
[18:42:16] <Tom_itx> haven't seen much yet you didn't go overkill on
[18:42:17] <gene77> I'm with Tom_itx but it sure looks like a good start from here.
[18:42:35] <Tom_itx> what will happen is the weld will start to tear at the top
[18:42:42] <Tom_itx> i know from experience
[18:42:45] <JT-Shop> come on if it looks right it will work
[18:42:48] <Tom_itx> i borrowed one that was built that way
[18:42:55] <Tom_itx> but only 3/4" plate
[18:43:11] <JT-Shop> on the plate?
[18:43:15] <Tom_itx> yeah
[18:43:21] <Tom_itx> i bent the plate too
[18:43:38] <JT-Shop> it will be glued on well
[18:43:43] <Tom_itx> i'm sure
[18:44:00] <Tom_itx> it looks plenty beefy really
[18:44:09] <gene77> But still needs braced from the back
[18:44:13] <JT-Shop> I'm going to cut the height down 1 1/2" inches for 8" total above the beam
[18:44:14] <Tom_itx> i had mine push the wood into the blade
[18:44:36] <Tom_itx> then if it got stuck you still had your cylinder free to jam something else in
[18:44:37] <JT-Shop> yes, large stiffeners will go on the back side
[18:44:59] <JT-Shop> this one will work vertical only so that can't work
[18:45:17] <Connor> I've seen them push the wood into the blade, thus keeping the wood in front of the machine and away from the sides for better access..
[18:45:46] <gene77> I have seen a couple to bent the backer off even when the had a 1/2" thick back brace, but the weld at the root of the backer broke.
[18:45:47] <JT-Shop> sorta like this http://imagebin.org/246470
[18:46:12] <JT-Shop> http://imagebin.org/246471
[18:47:21] <Tom_itx> yeah if yours tips up then you need to push the blade
[18:47:23] <gene77> What is guiding the wedge?
[18:47:32] <JT-Shop> gene77: that is a concern for sure and the welds if the same size as the smallest material is as strong as it gets
[18:48:21] <JT-Shop> some details are not done yet like the foot plate for the wedge, I'm undecided as to wich method I will use
[18:49:19] <gene77> I'd cage it on the flang of the I-Beam, with a cage about a foot long.
[18:49:21] <JT-Shop> you can kinda see the structure to back up the plate in the last photo
[18:49:35] <gene77> Drawiing, but yes.
[18:49:38] <Tom_itx> yeah4
[18:53:40] <gene77> trash is in the morning, so I'll let this thing watch itself & go put it out.
[18:57:23] <Tom_itx> JT-Shop, are the front wheels temporary?
[18:58:02] <JT-Shop> no, they are parking castors
[18:58:20] <Tom_itx> not so much to support it then?
[18:58:32] <JT-Shop> the tounge folds up for storage
[18:58:36] <Tom_itx> k
[18:59:08] <Tom_itx> i was gonna say you may want a bit more distance between them and the rear for better stability if they were the 'in use' platform
[18:59:49] <Tom_itx> iirc i just used a tongue jack on mine for the 3rd point
[19:00:03] <JT-Shop> yea, they are for parking manuvers only
[19:00:16] <Tom_itx> i noticed they're pinned
[19:00:56] <JT-Shop> yea they fold up for transport
[19:02:16] <Tom_itx> how hard is it gonna be to raise that beam with the cylinder on it?
[19:06:46] <Tom_itx> how hard is it gonna be to raise that beam with the cylinder on it?
[19:07:04] <JT-Shop-2> <JT-Shop> it will be pushing 200lbs when done I think
[19:07:05] <JT-Shop-2> <JT-Shop> so either a winch or a hydraulic jack to raise and lower
[19:07:11] <JT-Shop-2> http://imagebin.org/246474
[19:08:27] <Tom_itx> you may end up tying those up the other way if you have very hilly terrain
[19:09:55] <Tom_itx> damn his connection sucks
[19:10:16] <skunkworks> satellite
[19:12:01] <JT-Shop> darn lumpy connection tonight
[19:12:49] <JT-Shop> time for me to start dinner

[23:01:22] <brady2600> it was bullshit how cnn went right along and cut the live feed.
[23:01:49] <brady2600> what kind of press is it, if the cops can just demand it censored so they can be executioners in private.
[23:02:54] <brady2600> all government is a monopoly of voilence. We should have competing security firms instead of police departments you can't defund when they misbehave.
[23:03:47] <brady2600> The way it is, the fox is guarding the hen house. We are supposed to assume beyond all logic that all police are good, and they are only after bad guys. Its just not like that, the world isn't a black and white cartoon.
[23:05:13] <brady2600> Centralized monopolies on the initiation of violence are inherently immoral. Its absurd to think you can create one group of good people to watch over everyone else without creating a giant magnet for sociopaths that want exactly those powers that government entails.
[23:07:53] <brady2600> All of the services of government should be able to be achieved cheaper and more efficiently by competing groups. If they can't serve the needs of the population they should literally see their paychecks dry up. Cops that shoot at innocents should see themselves lose access to roads. They should have their pensions be declined to be managed. If one police department is accused of covering up crime, they should see an entirely diffrent s

[23:40:24] <brady2600> I used to be self described classically liberal, like the founding fathers, but ive come to the conclusion that the concept of minarchy is fatally flawed as America itself is an illustration of such. Limited government results in an explosion of productivity, and then all the bloodsuckers show up and want to take a bite. Dispite the best efforts of every man that proclaimed to try to limit the growth of the government, they inevitably fa

[23:50:05] <Jymmm> toastydeath: In tank fuel pump went out
[23:50:12] <toastydeath> oh lord
[23:50:49] <Jymmm> toastydeath: $110 for the deal ($600 for the pump + $500 labor), otherplaces wanted $500-$700
[23:51:17] <toastydeath> god DAMN that's a job i'd try to do at home first
[23:51:27] <Jymmm> toastydeath: See PM
[23:52:25] <Jymmm> toastydeath: NOBODY had written anything up, so I wanted to help out the next poor bastard.
[23:52:39] <toastydeath> that's awesome, video too
[23:53:01] <Jymmm> toastydeath: Well, not MY video, it was far too dark and cramped to take video
[23:53:26] <Jymmm> toastydeath: That is just one of the woes I had to deal with.
[23:53:33] <toastydeath> haha
[23:54:38] <Jymmm> toastydeath: Wiring manual, fuel filter, furl line tool, wheel chocks, ebay fuel pump, jack stands all came to around $125
[23:55:21] <toastydeath> nice
[23:55:33] <toastydeath> working on your own shit is balls cheap compared to any shop
[23:56:27] <Jymmm> toastydeath: EVERY auto parts in the area wanted $100 for the pump alone, plus another $20 for a new mesh filter
[23:56:58] <Jymmm> toastydeath: Even online wanted $90, I just got lucky
