[00:03:32] <andypugh> I have just been reminded of a good example of such a thing, as it just failed and stranded our 1916 fire engine

[00:05:05] <andypugh> It has a taper on the back axle worm shaft that fits a drive “knuckle”, and is drawn up with a nut. It has _two_ keyways at 90 degrees. So the keyways define an axis, and the taper defines an axis, and if you are _very_ lucky, they agree.
[00:06:39] <furrywolf> lol

[00:07:05] <furrywolf> use soft keys. :)
[00:10:13] <andypugh> That rather misses the point :-)
[00:11:18] <furrywolf> it does?
[00:11:59] <furrywolf> if they don't quite line up, the key will squish, instead of your taper not seating.
[00:12:25] <andypugh> And then they will squish some more under drive
[00:13:16] <andypugh> Any keys soft enough to squish under the tension of the (thin) nut would give way under drive
[00:13:46] <andypugh> This is a 9 litre engine
[00:13:50] <furrywolf> heh
[00:13:50] <furrywolf> so use only one key?
[00:14:11] <andypugh> Yes, that is exactly what we decided
[00:15:39] <XXCoder> darn!!
[00:15:49] <XXCoder> all wires has good enough conductivity
[00:16:24] <XXCoder> and damn! HOT outside.

[00:17:15] <ffurrywol> <furrywolf> so use only one key?
[00:17:20] <ffurrywol> <furrywolf> (and then it breaks under drive, too...)
[00:17:45] <andypugh> Well, the actual failure mode is not the key (directly)
[00:18:05] -!- furrywolf has quit [Ping timeout: 244 seconds]
[00:18:06] <ffurrywol> the failure mode is it gets loose, wobbles, makes bad noises, then goes crunch?
[00:18:24] <ffurrywol> or did it just break when you tightened the nut? heh

[00:20:29] <ffurrywol> sounds like it got loose first, then.
[00:20:48] <andypugh> Hard to say
[00:21:46] <andypugh> I really don’t think that there is enough nut preload for it to be a true friction drive, I think it relies on the key
[00:21:58] <andypugh> and a back axle is a constantly reversing load
[00:22:13] <ffurrywol> my connection seems to be sucking too badly to load the image. that happens after 5pm...
[00:22:45] <ffurrywol> my truck is old, but not that old... my shafts have splines on both ends. :)
[00:23:19] <andypugh> This one uses a steel “knuckle” in a square hole with two bronze slippers as the UK
[00:23:25] <andypugh> (UJ, I mean)
[00:23:28] <ffurrywol> coarse splines, 23 splines on a 1.5" diameter shaft, not modern fine splines, but still splines.
[00:24:02] <ffurrywol> you have universal joints on your back axle? shiny
[00:24:19] <andypugh> Pity you can’t see the picture, it shows the (broken) knuckle, the outer box and the slippers

[00:25:12] <ffurrywol> I'll try again...
[00:25:23] <ffurrywol> ohhh... when you said knuckle, I was thinking wheel knuckle...
[00:26:42] <ffurrywol> looks like it's loading this time, slowly
[00:27:16] <ffurrywol> all googles services are SLOW, due to using https for no reason, and tons of javascript bloat.
[00:27:22] <ffurrywol> hasn't even started loading the image yet, still loading bloat.
[00:29:59] <ffurrywol> yeah, that looks pretty mushed. looks like the other key spun afterwards and spread the taper too
[00:30:40] <ffurrywol> time to machine a new one?
[00:31:29] -!- patrickarlt has quit [Remote host closed the connection]
[00:32:46] <ffurrywol> unless the recess around the taper is required, skip it. it'll make it a lot stronger.
[00:34:29] <ffurrywol> apparantly I can't actually zoom in, despite it giving a zoom option.
[00:34:35] <ffurrywol> I hate google products.
[00:35:19] <ffurrywol> I click the + button, and all it does is enlarge the 317x564 thumbnail-ish image, making it pixelated.
[00:36:24] <ffurrywol> I guess if that recess contains the slippers, you probably don't want to machine new ones to solidly fill that space unless you have to...
[00:39:16] -!- nofxx has quit [Ping timeout: 244 seconds]
[00:39:23] <andypugh> Yes, the diamter round the taper can’t be much bigger or the joint won’t be able to articulate.

[00:45:41] <andypugh> The machine had become _horrible_ to use due to becoming unresponsive for 6 seconds out of every 30. I had decidedit was a failing HD, and re-installing the OS after a reformat was the last thing to try before a new HDD. So I was a bit surprised when it was all lovely again with a clean new system.
[00:46:33] <andypugh> So, n some ways, no restore does at least mean that I can’t return the system to the borked state.

[01:29:43] <os1r1s> Is there a relationship between pwm frequency and pdm frequency
[01:29:56] <andypugh> NO
[01:30:04] <andypugh> Sorry, I mean No
[01:30:19] <andypugh> PDm runs at the base thread frequency always
[01:31:03] <os1r1s> I need to set it for the 5i25 ... It seems to default
[01:31:20] <andypugh> PDM is what you get when you set PWM frequency to zero (not inherently, that is how the driver is written, rather than a law of physics)
[01:31:38] <andypugh> Ah, that’s different
[01:37:04] <andypugh> http://www.linuxcnc.org/docs/html/man/man9/hostmot2.9.html#pwmgen
[01:37:17] <os1r1s> andypugh: I looked at that, but I'm not getting it
[01:37:56] <os1r1s> I think since my output type is 1 it may not matter
[01:37:59] <andypugh> Set output-type to 3 and set pdm_frequency to the required number
[01:38:11] <andypugh> Do you want PDM?
[01:38:32] <andypugh> Or am I answering the wrong question?
[01:38:33] <os1r1s> No, I don't. I don't think so anyway. I want to PWM
[01:38:45] <os1r1s> But it makes me specify *something*

[02:17:35] <ffurrywol> yay, two more bug zappers installed. if each one kills 10 mosquitos a night, that's .000001% of the number flying around!
[02:18:09] <zeeshan|2> why are you killing mosquitos
[02:19:53] <ffurrywol> because they're evil parasites that carry disease and cause large painful lumps?
[02:20:03] <zeeshan|2> they are food for spiders
[02:20:06] <zeeshan|2> and birds
[02:20:08] <zeeshan|2> and bats
[02:20:12] <zeeshan|2> !
[02:20:19] <zeeshan|2> and also fish
[02:20:35] <zeeshan|2> only female mosquitos bite
[02:20:40] <zeeshan|2> male mosquitos are chill
[02:21:11] <zeeshan|2> and it is a well known fact that bug zappers kill more good buds
[02:21:14] <zeeshan|2> bugs like moths etc
[02:21:17] <zeeshan|2> than mosquitos :P
[02:21:50] <ffurrywol> moths aren't good either. they eat my plants!

[02:22:12] <ffurrywol> mosquitos don't seem to get caught in spiderwebs.
[02:22:27] <ffurrywol> birds seem to be active in the morning, mosquitos in the evening.
[02:22:40] <ffurrywol> I don't know how many bats are around here. probably not too many.
[02:22:43] <ffurrywol> no fish
[02:23:21] <zeeshan|2> frogs im sure you have
[02:23:29] <zeeshan|2> i was googling why we dont eradicate mosquitos
[02:23:33] <zeeshan|2> cause i hate them as well
[02:23:39] <zeeshan|2> then realized, every damn creatue seems to have a purpose
[02:23:44] <zeeshan|2> no matter how annoying it is
[02:24:05] <ffurrywol> some areas do have mosquito eradication programs
[02:24:50] <zeeshan|2> man im on antibiotics

[02:28:33] <zeeshan|2> i think duct tape is a shitty conductor

[02:29:10] <zeeshan|2> and vaporize
[02:29:17] <zeeshan|2> it actually went boom
[02:29:24] <zeeshan|2> with a plasma ball. and the chip was only 1/4"
[02:29:27] <zeeshan|2> never seen that before

[02:31:19] <ffurrywol> I saw someone trimming a tree drop a limb on the power lines... where it hit it started an arc which quickly turned into a ball lightning-ish light show, which then travelled down the wires following the narrow spot caused by the impact wave in the wires...
[02:31:41] <andypugh> Sounds pretty. From a distance
[02:32:19] <ffurrywol> it went down to the far end, bounced, and started coming back, then went away. along with all the lights in the area. then he had to call pg&e...
[02:32:39] <andypugh> Lucky not to be calling A&E
[02:32:49] <zeeshan|2> haha
[02:32:58] <ffurrywol> they had to come out and change a fuse on one of the poles, and he got a lecture on how he shouldn't drop branches on trees, as it makes them very unhappy...

[02:34:12] <zeeshan|2> andypugh: can you confirm an expression for me
[02:34:21] <andypugh> zeeshan|2: I would call him an engineer. The IMechE might disagree. The IMechE don’t think I am an engineer.
[02:34:24] <zeeshan|2> when brits say "to be american about it"
[02:34:32] <zeeshan|2> is that another way of saying
[02:34:34] <zeeshan|2> "this is slang"
[02:34:44] <zeeshan|2> whos imeche
[02:35:03] <andypugh> I actually have no idea what that phrase would mean.
[02:35:09] <zeeshan|2> dont lie
[02:35:16] <zeeshan|2> ive heard so many british people say it on youtube
[02:35:20] <zeeshan|2> especially "intellects"
[02:35:30] <zeeshan|2> :]
[02:35:42] <zeeshan|2> "inst of mech eng"
[02:35:43] <zeeshan|2> i see

[02:41:34] <zeeshan|2> hey, if someone lists their ebay listing wrong
[02:41:38] <zeeshan|2> like they say free shipping
[02:41:48] <zeeshan|2> when they actually meant to charge for shipping, what happens?
[02:41:55] <zeeshan|2> and youve won the auction
[02:41:56] <ffurrywol> some sellers will honor it, some will just cancel the transaction.
[02:42:23] <andypugh> In southern Spain leaving a tip is almost seen as an insult. The implication that you are on a higher social standing than the waiters, and they should appreciate your largesse. In the US you are likely to get in trouble for not tipping.
[02:42:39] <ffurrywol> ebay does not penalize sellers for cancelling transactions. in theory, they have a seller non-performance policy, but in reality they never cancel accounts or otherwise punish sellers for cancelling transactions.
[02:42:42] <zeeshan|2> andypugh: its crazy how different areas of the world work like that
[02:42:45] <zeeshan|2> even in pakistan its like that
[02:42:51] <zeeshan|2> tip is saying "im better than you"
[02:42:56] <zeeshan|2> "peasant."
[02:43:11] <jdh> tipping is uncivilized
[02:43:15] <ffurrywol> I only tip because around here restaurants are allowed to pay well under minimum wage and tell staff to make up for it with their tips.
[02:43:19] <ffurrywol> otherwise I think it should be abolished.
[02:43:25] <andypugh> When you think about it, that is what you are saying.
[02:43:26] <zeeshan|2> ffurrywol: same here
[02:43:35] <zeeshan|2> andypugh: its a diff context here though

[02:43:58] <zeeshan|2> some servers really do go out of your way for you to have a decent time out with the freinds
[02:44:00] <andypugh> Yes, your waiting staff are basically slaves :-)
[02:44:01] <jdh> and by 'going out of your way', I mean 'your job'
[02:44:08] <zeeshan|2> jdh no
[02:44:11] <zeeshan|2> they can do their job
[02:44:16] <zeeshan|2> and then they can do more than their job
[02:44:20] <zeeshan|2> dont get dirty ideas :P
[02:44:26] <furrywolf> wait staff is considered a very low status job around here.
[02:44:42] <jdh> depends on the venue

[02:44:56] <Tom_itx> hah
[02:45:23] <furrywolf> I wish I could visit britain... stop by a few random curry houses... and then visit pakistan and compare... and I'm sure both would be a lot better than what you get here.

[02:52:52] <furrywolf> your friends aren't very good hindus. :)
[02:52:55] <andypugh> I recall visiting Nirmal’s in Sheffield. Mrs Nirmal was from Delhi, and most UK curry vendors are Bangladeshi. My friend asked for a chicken biryani and Mrs Nirmal said “Oh, sir, we do _far_ better curres than that!” and basically refused to sell him one.
[02:53:08] <zeeshan|2> lol
[02:53:16] <zeeshan|2> bengalis make their food a bit weird
[02:53:19] <zeeshan|2> same with gujaratis
[02:53:26] <zeeshan|2> they add fucking sugar in their butter chicken
[02:53:28] <zeeshan|2> its disgusting
[02:53:34] <zeeshan|2> (sorry about the profanity!)
[02:53:36] <furrywolf> sugar? eww
[02:53:39] <zeeshan|2> but it is absurd
[02:54:15] <andypugh> Her arguiment was that a real Biryani is lovely, but takes an hour to cook, and has to be eaten right then. You can’t do a real Biryani in a restaurant context.
[02:54:21] <furrywolf> the guy that owned the place here (pakistani) made a really good beef karahi...
[02:54:29] <zeeshan|2> furrywolf: omg!
[02:54:31] <zeeshan|2> that stuff grew on me
[02:54:34] <zeeshan|2> i like chicken karahi
[02:54:49] <zeeshan|2> andypugh: do you guys have a lot of different types of food in uk?
[02:55:09] <zeeshan|2> where i live, ive got arab, indian/paki, italian, greek, carribean, all sorts
[02:55:21] <zeeshan|2> jerk chicken is pretty damn good
[02:55:27] <furrywolf> andypugh: most restaurant biryani I think is actually a pulao.
[02:55:32] <andypugh> Yes, because we have been told for centuries that our native stuff is rubbish.
[02:55:39] <zeeshan|2> bs
[02:55:42] <zeeshan|2> i love british food
[02:55:48] <furrywolf> compared to indian, everything is rubbish. :P
[02:55:48] <zeeshan|2> starting with custard
[02:56:06] <zeeshan|2> you can't beat a good fish and chips
[02:56:23] <andypugh> Spotted dick and custard. Sounds sily, bit it’s great
[02:56:37] <zeeshan|2> jeez whatr is this name
[02:56:45] <furrywolf> I don't mind british food, but it's roughly impossible to get here.
[02:57:08] <zeeshan|2> i get birds custard!

[02:57:41] <zeeshan|2> delicious
[02:58:23] <zeeshan|2> yorkshire pudding is another good one
[02:58:40] <zeeshan|2> i wonder if rhubarb pie is a british recipe

[02:59:18] <zeeshan|2> https://en.wikipedia.org/wiki/Rhubarb_pie

[02:59:31] <furrywolf> no black pudding, no brussel sprouts, no scottish or irish (mmm, haggis),...

[03:01:04] <andypugh> Yes, well, it would be if I felt tired
[03:01:28] <furrywolf> there's very little international cuisine where I am.
[03:01:36] <furrywolf> we have a bunch of chinese restaurants, and they're all fucking garbage.
[03:01:38] <zeeshan|2> furrywolf: that sux :/
[03:01:46] <zeeshan|2> i despire chinese food
[03:01:51] <zeeshan|2> at restaurants
[03:01:58] <furrywolf> we have two indian places, one is garbage, the other isn't bad, but doesn't have much variety, and is very expensive.
[03:01:58] <zeeshan|2> no matter where you go, its loaded with msg
[03:02:03] <malcom2073> I love me a good chinese buffet
[03:02:28] <furrywolf> we have a german place, and it's both garbage and stupidly overpriced. you order bratwurst, they take it out of a store-bought package, stuff it in the microwave, plop it on a plate, and charge you $15.
[03:03:16] <furrywolf> there's a couple italian places, but they're overpriced and not very good.
[03:03:28] <zeeshan|2> haha
[03:03:33] <zeeshan|2> gotta love microwaved food
[03:03:50] <furrywolf> there's several mexican places, but they're all crap too... I have a mexican coworker who's tried every one of them, and confirms none of them resemble food that would be served in mexico.
[03:03:52] <zeeshan|2> hows your grocery stores though
[03:03:56] <zeeshan|2> do you have a lot of fruits and vegies
[03:03:59] <zeeshan|2> cali is known for it
[03:03:59] <furrywolf> yes
[03:04:15] <zeeshan|2> i think they provide 70% of usa's fruits and vegies
[03:04:18] <furrywolf> there is one good Vietnamese place, but it's pretty pricey.
[03:04:27] <zeeshan|2> pho is pretty good
[03:04:33] <zeeshan|2> but kinda bland too
[03:04:39] <andypugh> It was wierd in Spain earlier this month. If you order beer they bring free food. At the end of the night you have had 4 beers and enough food for all practical purposes and get a €10 bill.
[03:04:47] <furrywolf> they know me there and dump lots of thai hot peppers in my dishes... normally when serving americans they don't use any.
[03:04:50] <zeeshan|2> andypugh: haha
[03:04:55] <zeeshan|2> is spanish food similar to mexican?
[03:04:57] <zeeshan|2> ive never had it
[03:05:13] -!- Mr_Sheesh has quit [Remote host closed the connection]
[03:06:00] <furrywolf> I've asked a couple staff about it, and they say that every time they serve americans food prepared like it would actually be back home, they get complaints, people leaving without paying, etc. or, as one waitress put it, "back to kitchen! back to kitchen! every time, back to kitchen!".
[03:06:35] <andypugh> Well, their real food is varied and nice. What you get with the beer is Tapas
https://en.wikipedia.org/wiki/Tapas so things like fried baby octopus, calamari, potato croquettes, fried chicken…
[03:06:36] <furrywolf> me, I love a handfull of fresh thai hots chopped into my meal. :)
[03:07:32] <zeeshan|2> cool
[03:07:37] <zeeshan|2> can you name a entree dish
[03:07:40] * zeeshan|2 wants to look it up
[03:07:49] <furrywolf> I've never had spainish cuisine.
[03:07:52] <furrywolf> no idea what it's like
[03:08:06] <zeeshan|2> http://www.taste.com.au/images/recipes/sfi/2010/06/24907_l.jpg
[03:08:08] <andypugh> Fried baby octopus is the only dish that actuallt upsets me. Well, I guess I would feel the same about deep fried kittens or baby hamsters.
[03:08:09] <zeeshan|2> i dont know what th ehell this is
[03:08:15] <zeeshan|2> but it look delicious

[03:08:30] <furrywolf> re beef in india... "Last month, however, this changed. Beef dishes were forced off the menu when Maharashtra, the country’s second most populous state, which incorporates Mumbai, extended a ban on cow slaughter to bulls and oxen, and made the sale of beef punishable by up to five years in prison. A few weeks later, the state of Haryana passed similar legislation. Prime Minister Narendra Modi’s office has suggested that such bills a
[03:08:56] <furrywolf> omlette or quiche of some variety
[03:09:16] <zeeshan|2> id think its kind of like portuguese food
[03:09:18] <zeeshan|2> that ive had a lot of
[03:09:22] <furrywolf> I like both omlettes and quiche, so I guess I have had spanish food, just didn't think of it. heh.
[03:09:24] <andypugh> zeeshan|2: Spanish Ommelette. Potato, eggs and (in that case) Chorizo
[03:09:34] <zeeshan|2> nice
[03:09:59] <furrywolf> zeeshan|2: so, no, mumbai people don't eat a lot of beef... it's currently illegal there, in fact.
[03:10:24] <andypugh> I wonder on what basis?
[03:10:44] <zeeshan|2> furrywolf: no!

[03:10:48] <zeeshan|2> lol
[03:10:53] <malcom2073> I like calamari, but when they use baby squid I'm not fond of it
[03:11:30] <furrywolf> I don't like deep-fried food.
[03:11:47] <andypugh> Deep fried Mars Bars?
[03:11:51] <malcom2073> I like most every food
[03:11:54] <zeeshan|2> deep fried ice cream

[03:14:41] <furrywolf> s/the//
[03:15:25] <furrywolf> by the time it makes it all the way to california, you only get A light and A dark... can't even get B... I want C!
[03:16:50] <furrywolf> A light is for people who want flavorless sugar. A dark is for people who want almost flavorless sugar. B is getting there. C is for people who actually, you know, like maple.
[03:16:55] <andypugh> I am currently working through the “Flashman” books. The main character is a despicable cad, which is quite an interesting way to describe history, because he can take contrary views on almost everything. It makes fascinating readng (and the plots are fun). Very interesting on the slave trade, indian wars (US) and indian wars (UK in India)

[03:24:17] <andypugh> Flashman’s view of US aborigines was that they were very badly treated, horribly abused and were _also_ cruel unpleasant savages. And basically neither side unserstood the other at all. (In very fundamental ways). We probably won’t see that again until (and if) we meet ETs. Though it still might be worth considering in dealing with the likes of Boku Hartam who really don’t even agree with the West on what constit
[03:24:17] <andypugh> admirable. According to the Flashman books (and these are novels, so let’s not take things as fact, but consider the scenario) the Apache admired nothing more than a cunningly contrived theft.

[03:27:44] <andypugh> If you step back from the Judeo-Christian worldview, what isn’t to appreciate in clever scheming? We all like a tale of a well-planned con, after all. As long as we are not the victim. It’s not a big step to considering that a virtue, and having a very different basis of society. The clever and ruthless get rich at the expense of the slow and meek. Hey, hang on….
[03:28:06] <furrywolf> hrmm, apparantly as of four months ago, there's a new grading system for maple syrup, which should be showing up in stores soon.

[03:33:01] <furrywolf> the grading system is backwards, if you like flavor, not sugar... grade A is the most sugar, least flavor... grade C is the most flavor.
[03:33:19] <zeeshan|2> are you sure
[03:33:22] <zeeshan|2> grade cis the dark stuff
[03:33:27] <zeeshan|2> the higher the grade the more lighter the color
[03:33:32] <zeeshan|2> more refined it is
[03:35:09] <furrywolf> grade A is the stuff you can see through, grade C is the stuff you can't.

[15:23:00] <tiwake> CUPS for 3D printers does not seem like a good idea though
[15:24:18] <os1r1s> tiwake: Microsoft supports it, so this is an attempt to maintain equal functionality.
[15:27:19] <tiwake> os1r1s: supports "it"? do I need to redesign my 3D printer interface?
[15:27:54] <tiwake> I mean, some 3D printers the only way is to load the 3D model into it directly
[15:29:12] <furrywolf> my guess would be they're talking about printers that are based on inkjets and layers, where processing for them is similar to printing on paper, just you add another layer instead of feed another page... but that's just a guess.

[17:58:47] <os1r1s> archivist: So I have an e-stop switch which grounds pin 15 (GPIO 3) when I hit the button. So in the hal, do you think it should be inverted or normal?
[18:01:21] <archivist> PCW has recommendations for correct e stop sense
[18:02:30] <os1r1s> archivist: Do you know where I can find those?
[18:03:03] <archivist> in the logs for the channel, somewhere
[18:04:35] <Tom_itx> os1r1s, i'm doing a couple special things on the spindle code
[18:05:09] <Tom_itx> i add a delay component to delay switching the relays until they are no or low load to save the contacts
[18:05:16] <Tom_itx> it's only a few ms delay
[18:05:29] <Tom_itx> for fwd/rev
[18:06:16] <Tom_itx> and since i'm using the stock sherline control, i'm also using a SSR to enable it along with the fwd/rev relays
[18:06:31] <Tom_itx> a purpose built one wouldn't need all that
[18:07:50] <os1r1s> Tom_itx: I have an SSR to control it in one direction. And I have PWM to control the speed. How are you reversing it?
[18:07:57] <Tom_itx> the stock control has an 'inhibit' pin that resets the control so it goes thru it's ramp up routine on start
[18:08:13] <Tom_itx> i use a DPDT relay
[18:08:53] <Tom_itx> using the 7i47S for spindle PWM
[18:10:59] <archivist> os1r1s, he recommends a normally closed switch so a broken wire also creates an estop condition
[18:12:33] <os1r1s> archivist: This one is an NC switch
[18:12:48] <archivist> that is correct
[18:13:45] <archivist> and this was in some conversation 2015-07-31 21:57:29 | net estop-ext <= hm2_5i25.0.gpio.015.in
[18:14:28] <archivist> os1r1s, I am using my local database to trawl logs :)
[18:14:29] <os1r1s> archivist: Right. From our discussion yesterday. Then it became pin 003 since that is the GPIO pin. But its not working correctly.
[18:15:34] <archivist> that would have been? #linuxcnc | PCW | 2015-07-31 22:00:24 | net estop-ext <= hm2_5i25.0.gpio.003.in
[18:15:46] <os1r1s> archivist: Yep
[18:17:51] <archivist> I have not implemented estop on mine yet, got used to using the ESC key
[18:19:22] <os1r1s> archivist: Mine cuts the power to the motors, so I could use it without linuxcnc being aware. But I'd prefer it all to work
[18:19:35] <Tom_itx> net estop-loop iocontrol.0.emc-enable-in <= hm2_[HOSTMOT2](BOARD).0.7i84.0.0.input-13
[18:19:47] <Tom_itx> that can't be right...

[18:39:49] <archivist> os1r1s, that is a sign of an electrical problem or looking at the wrong pin
[18:40:09] <os1r1s> archivist: The thing is, it worked fine connected directly to the parallel port
[18:40:29] <os1r1s> Which leads me to think the wrong pin ...
[18:40:46] <archivist> or no pull up
[18:41:32] <archivist> or pull down whichever is needed
[18:41:48] <os1r1s> The W4 jumper is set up which means it the pull-ups are enabled
[18:44:24] <os1r1s> I'm wondering if something funny is happening with the charge-pump
[18:45:11] <archivist> use a real multimeter/scope to check voltages on wires
[18:45:14] <os1r1s> archivist: In the old config the e-stop was tied to the chargepump.enable. But in this one I'm using stepping for the chargepump
[18:47:16] <pcw_home> looks like the estop switch should be a normally closed switch to ground (open for estop which is signaled as fault on pin 15)
[18:49:14] -!- Nick001-shop [Nick001-shop!~chatzilla@50.107.174.11] has joined #linuxcnc
[18:49:15] <os1r1s> pcw_home: The weird thing is, This was my config using the par port directly ... "net estop-ext <= parport.0.pin-15-in"
[18:50:33] <os1r1s> pcw_home: Shouldn't that translate to "et estop-loop iocontrol.0.emc-enable-in <= hm2_[HOSTMOT2](BOARD).0.gpio.003.in"
[18:50:44] <pcw_home> it should
[18:51:31] <os1r1s> pcw_home: I had this too because I was using the software charge pump ... net estop-out charge-pump.enable iocontrol.0.user-enable-out
[18:53:09] <os1r1s> pcw_home: Would the stock with a normal parallel port be to have them pulled up or down?
[18:53:22] <pcw_home> pulled up
[18:54:06] <os1r1s> Maybe I should try the software charge pump (or disable it) to see if thats what is interfering with it
[18:55:55] <pcw_home> It should not make any difference except that you cannot get out of faults state if the G540 chargepump is enabled and the signal is not there
[18:57:48] <pcw_home> so you are saying the you cannot see a change in GPIO3 ( via halmeter _NOT _show )
[18:57:49] <pcw_home> if the G540 fault state changes (as indicated by the red fault LED on the G540)
[18:58:09] <os1r1s> pcw_home: Correct, I don't see a change in GPIO03 no matter what I do
[18:58:32] <pcw_home> and the red fault light is changing?
[18:58:51] <pcw_home> and you are using halmeter to look at the pin
[18:58:57] <pcw_home> ?
[18:59:08] <os1r1s> pcw_home: I did not look at the fault light. I will check that next. I am using halmeter to look at the pin
[19:00:06] <os1r1s> pcw_home: If I watch the e-stop-loop pin, I can see it flip from true to false before it flips off
[19:03:02] <os1r1s> pcw_home: Do you think the parallel port cable could matter. It is the same cable that worked with the parport, but an older cable.
[19:03:05] <pcw_home> probably a bootstrap problem in the hal file with the chargepump enable
[19:03:21] <os1r1s> pcw_home: I dont' have chargepump enable on at all
[19:03:56] <pcw_home> the g540 has its chargepump logic disabled?
[19:04:14] <os1r1s> No. I'm using this ...
http://pastebin.com/uQ50T4qr
[19:05:03] <pcw_home> In any case you should not expect GPIO3 to go low unless you have the red LED out on the G540
[19:05:05] <os1r1s> With the e-stop not set in hal (and that code), I can use the machine
[19:05:56] <pcw_home> Yeah looks like a boostrap issue

[19:08:21] <os1r1s> pcw_home: Here is my hal file ...
http://pastebin.com/ALWTD3Eh
[19:09:49] <pcw_home> because the G540 fault signal is the "OR" of Estop in and the running state of the drives
[19:09:51] <pcw_home> I suspect you must enable the chargepump with something other than axis.0.amp-enable-out
[19:10:12] -!- [cube] has quit [Ping timeout: 272 seconds]
[19:10:23] <pcw_home> or you will never be able to get out of ESTOP
[19:10:52] <os1r1s> pcw_home: If I invert the logic, that is exactly what happens
[19:11:08] <pcw_home> inverting the logic is wrong
[19:12:18] <pcw_home> the polarity is correct (FAULT is active high as is etop in ) but theres a bootstrap issue with the chargepump
[19:12:58] <os1r1s> pcw_home: Ok. So how would I enable it without the axis.0.amp-enable-out?
[19:13:34] <pcw_home> because the fault input is not just Estop, its also "no chargepump"
[19:14:17] <os1r1s> And this still makes sense when the machine will move without the e-stop enabled in the hal?
