[01:28:18] <zeeshan> holy the world will i tell what model sensor this is :{
[01:28:42] <zeeshan> poor th ing has seen better days
[01:36:19] <archivist> looks magnetic
[01:36:25] <zeeshan> really?
[01:36:37] <zeeshan> might explain why the card it connects to
[01:36:40] <zeeshan> seems to be outputting 24vdc
[01:36:43] <zeeshan> and not 5v
[01:41:15] <archivist> there can be optical or some form of magnetic or capacitive
[01:42:05] <archivist> magnetic has tow basic types one being hall effect the other a coil
[01:42:09] <archivist> two
[01:42:18] <zeeshan> i dont see a coil on this
[01:42:35] <archivist> internal potted
[01:43:53] <archivist> it can be an oscillator which changes Frequency with the paddle, capacitive are like that too
[01:44:08] <zeeshan> im still reverse engineering the circuit
[01:44:10] <zeeshan> that this connects to
[01:44:16] <zeeshan> its also responsible for speed gear selection
[01:45:57] <archivist> could even be a version of proximity detector
[01:46:30] <archivist> opto in a dirty environment can be unreliable
[01:46:52] <Loetmichel> mornin'
[01:47:50] <archivist> unlikely but there were magnet and reed switch methods

[03:04:25] <zeeshan> has been reverse engineered
[03:04:31] <zeeshan> http://www.docdroid.net/ljex/speed-selector.pdf.html
[03:08:08] <archivist> you do use some crappy sites docdroid just has circling blobs fo rme
[03:09:09] <zeeshan> whats a better side
[03:09:13] <zeeshan> * Site
[03:09:59] <zeeshan> https://pdf.yt/d/3UuBLq6IAeRxgH9X
[03:10:00] <zeeshan> better?
[03:11:16] <archivist> both allow download but fail utterly at online view that they seem to be all about
[03:11:34] <zeeshan> lol
[03:11:56] <archivist> pdf is by far the worst format invented
[03:12:02] <zeeshan> i like it
[03:12:08] <zeeshan> ghostscript is the worst!
[03:12:54] <archivist> diagram reminds me of...badly draw boy
[03:13:03] <zeeshan> well
[03:13:12] <zeeshan> to be honest this is my first time reverse engineering a circuit
[03:13:13] <zeeshan> from a pcb
[03:13:16] <zeeshan> i tried my best
[03:13:30] <zeeshan> its quite hard to follow each trace
[03:13:32] <zeeshan> and figure out whats going on
[03:13:35] <zeeshan> its tedious
[03:13:42] <archivist> flow goes left to right not bottom to top
[03:13:53] <zeeshan> well the way the layout is
[03:13:56] <zeeshan> is how it's layed out on the pcb
[03:14:00] <zeeshan> i didnt want to lose track
[03:14:40] <zeeshan> do you know why there would be transistors at the pins?
[03:14:57] <archivist> open collector
[03:15:16] <zeeshan> that term is not familiar with me
[03:15:20] <zeeshan> in a car ecu
[03:15:29] <zeeshan> if you have that kind of setup, and you ground that transistor
[03:15:33] <zeeshan> you basically change the state
[03:15:43] <zeeshan> is that what an open collector is? :P
[03:15:55] <archivist> those things you call cap I bet are resister networks
[03:16:11] <zeeshan> really?
[03:16:21] <zeeshan> i measured resistance between each adjacent pin
[03:16:23] <zeeshan> there was no resistance
[03:16:28] <zeeshan> thats why i thought they were caps
[03:16:31] <zeeshan> cap networks
[03:16:34] <renesis> press the probes in harder
[03:17:07] <archivist> board is probably coated in a varnish
[03:17:14] <zeeshan> nahh
[03:17:22] <zeeshan> the solder joints are exposed
[03:17:40] <zeeshan> when i power 24vdc @ pin 5 and ground pin 8 or 9
[03:17:44] <renesis> sometimes the solder joints or the probes get a bit oxidized
[03:17:48] <zeeshan> the board powers up.
[03:18:08] <zeeshan> i measure 24vdc between pin 6 & ground
[03:18:15] <zeeshan> and also 24vdc between pin 7 and ground
[03:18:22] <zeeshan> all other pins are at 0.
[03:18:43] <archivist> passenger arrived /me gone
[03:18:51] <zeeshan> then i monitor pin 1 and ground and take a magnet and try to hover it around all the hall switches
[03:18:53] <zeeshan> nothing happens :P
[03:18:58] <zeeshan> archivist: cya!
[03:22:11] <zeeshan> ok sleep time
[03:22:15] <zeeshan> will attack this more tomorrow
[05:18:32] <Deejay> moin
[07:03:10] <alex_joni> Jymmm: yo
[08:21:59] * Cylly just has ordered another 120 packs of "mama" noodle soup... next 2 months supper at the company is secured ;-)
[08:22:33] <Cylly> ... was about time, i only have 2 packs duck and one pack beef left of the last order ;-)
[10:17:56] <taiden> hey all
[10:18:01] <taiden> getting my linuxcnc computer built
[10:18:15] <taiden> looks like i have a pci-e and a space for a usb stick
[10:18:18] <taiden> any thoughts on getting wifi on this thing?
[10:18:31] <taiden> last time i tried was with linuxcnc 2.5 and had bad luck
[10:37:01] <taiden> also, i want to run this off USB, should i use the Live usb to install to another USB drive? Or just run it as Live?
[10:37:26] <Cylly> i wouldnt run the live
[10:37:47] <Cylly> ... could be a bit challenging to do the config every time tyou start the machine ;-9
[10:38:25] <Cylly> but i wouldnt do that, running it from aflashdrive on usb
[10:38:25] <zeeshan|2> it doesnt take long to install it :P
[10:38:36] <Cylly> i would use a sata drive, either ssd or rotating rust
[10:38:47] <Cylly> because if the usb interrupsts and speed stuff
[10:38:57] <Cylly> unlesss you have a mesa card
[10:39:56] <Loetmichel> s/if7of
[10:45:59] <zeeshan|2> http://www.exfactoryauctions.com/AuctionDetail.aspx?recnum=FE-230435&searchType=5&lotNo=A111914.2&searchText=&brand=MITUTOYO&closedate=&LotName=BUNK%27N%20BED%20FURNITURE
[10:46:00] <zeeshan|2> wow
[10:46:13] <zeeshan|2> 4'x8'x10" thick granite table
[10:46:14] <zeeshan|2> nice!
[10:48:18] <taiden> OK makes sense
[10:48:28] <taiden> i have a sata 500 gb hdd lying around. seems overkill but who cares i guess
[10:48:47] <taiden> i was hoping to run it right off the usb stick but if it's going to effect latency then what's teh point
[10:49:09] <taiden> but if the latency happens to be good on the usb stick, are there any issues with just running it as a live cd (usb)?
[10:49:37] <taiden> oh I see, so the config resets each time. i thought if it was USB it might just work out the box like an install
[10:53:25] <taiden> what about something like this? http://www.amazon.com/MyDigitalSSD-Super-Boot-Drive-42mm/dp/B00KBZH746/ref=cm_cr_pr_product_top
[10:53:31] <taiden> does that plug into PCI-E?
[10:57:46] <zeeshan|2> vfds , servo drives, power supplies
[10:58:41] <zeeshan|2> would a disconnect switch for the primary need to be rated for highly inductive loads? my logic says no because you're not disconnecting a motor load directly?
[10:58:45] <zeeshan|2> can someone confirm
[11:00:39] <pcw_home> Unless it is powering a large transformer it will not be switching inductive loads
[11:01:29] <zeeshan|2> there isnt a large transformer :D
[11:01:49] <zeeshan|2> http://www.automationdirect.com/adc/Shopping/Catalog/Circuit_Protection_-z-_Fuses_-z-_Disconnects/Disconnect_Switches/UL_508_Rated_Non-Fusible_Disconnects/DIN_Rail_or_Panel_Mount_%2863-125_Amps,_SD2_Series%29/SD2-125-RR
[11:01:52] <zeeshan|2> i was thinking of using this thing
[11:03:26] <LeelooMinai> I feel cheap now, because I payed 1/10th price:) http://www.aliexpress.com/item/Emergency-Stop-Push-Button-660V-Switch-1NC/1269969461.html
[11:03:38] <Loetmichel> taiden: i have about 250 80gb sata1 hdd here at the company... i could you lend opne or two, but i thibnk shipping wioll exceed the rest value of them
[11:03:49] <zeeshan|2> LeelooMinai: are you comparing that to mine?
[11:03:54] <zeeshan|2> theyr'e not the same thing
[11:04:07] <zeeshan|2> you're comparing an e-stop switch switch a 125A disconnect switch
[11:04:27] <LeelooMinai> zeeshan|2: Well, they are switches
[11:04:35] <zeeshan|2> yea one takes like 10amps
[11:04:37] <zeeshan|2> the other takes 125amps.
[11:05:01] <zeeshan|2> my systems been designed for 100amp draw
[11:05:33] <_methods> you're on residential?
[11:05:37] <LeelooMinai> I see, well, so that's more like this: http://www.aliexpress.com/item/AC-230V-400V-100A-35mm-Mounting-Rail-Overload-Protection-Disconnect-Switch/1267806452.html
[11:05:39] <zeeshan|2> yea
[11:06:04] <LeelooMinai> But damn... why do you need 100A...
[11:06:26] <zeeshan|2> wheres the KA rating for that switch
[11:06:27] <zeeshan|2> that you posted
[11:06:37] <zeeshan|2> kA
[11:06:41] <zeeshan|2> (short circuit rating)
[11:06:55] <LeelooMinai> I don't know - ask them:)
[11:07:14] <zeeshan|2> i try not to buy non approved shit
[11:07:20] <zeeshan|2> so if my house burns down
[11:07:23] <zeeshan|2> i can show em!
[11:07:32] <zeeshan|2> =P
[11:07:36] <LeelooMinai> If it burns out, they will not recognize it anyways:)
[11:07:43] <zeeshan|2> i'll still have my usb!
[11:07:57] * Loetmichel had some contactors in the tatra truck that were desinged to switch the starters... which draw 1000A at 24V ;-9
[11:08:01] <zeeshan|2> 60 gb of my life is on it :{
[11:08:17] <Loetmichel> massive copper bar being pulled onto two other copper batrs ... russin tech M;-)
[11:08:24] <zeeshan|2> LeelooMinai: can you see DXF files?
[11:08:25] <Loetmichel> russian#
[11:08:25] <zeeshan|2> or dwg
[11:09:10] <LeelooMinai> zeeshan|2: Sometimes you have to google for those things - but they may be somewhere.
[11:11:09] <LeelooMinai> zeeshan|2: They are sold everywhere: http://www.amazon.com/Circuit-Control-Isolating-Disconnect-Switch/dp/B0097B7RRW
[11:11:10] <zeeshan|2> LeelooMinai: i already know what im buying
[11:11:25] <zeeshan|2> it's not a question about where to buy it from
[11:11:27] <LeelooMinai> I doubt they are faulty in some way.
[11:11:45] <zeeshan|2> it was a question about the loads theyre switching
[11:12:14] <zeeshan|2> theres no ul rating on that?
[11:13:12] <zeeshan|2> nor csa
[11:13:34] <LeelooMinai> You are to picky:) Switch is a switch:p
[11:13:43] <zeeshan|2> there are ratings for a reason
[11:13:53] <zeeshan|2> i've seen what happens (well not with a dinky little 100A switch)
[11:14:07] <zeeshan|2> but with 1000A switches when they're designed like shit
[11:14:12] <zeeshan|2> they blow up in your face
[11:14:16] <zeeshan|2> during a short circuit
[11:14:28] <LeelooMinai> It's probably cloned from something and tested
[11:14:30] <zeeshan|2> good ones route the plasma away from you
[11:14:47] <LeelooMinai> Chinese may be cheap, but they are not stupid
[11:14:57] <zeeshan|2> most chinese stuff is junk
[11:15:15] <zeeshan|2> taiwanese is great
[11:15:35] <LeelooMinai> Only the things designed to be so. They can make as good things as they want, but it must calculate for them.
[11:16:03] <zeeshan|2> i agree with that completely
[11:16:18] <zeeshan|2> apple products an example of that
[11:16:22] <LeelooMinai> It's a bit of an art - buying things from places like aliexpress
[11:16:36] <zeeshan|2> i refuse to buy shit with no certifications
[11:17:03] <LeelooMinai> You need to do some research, have common sense and good judgement - then you will get pretty much what you expected and it may be fine for the purposes
[11:17:13] <zeeshan|2> yet it still doesnt have a rating
[11:17:15] <zeeshan|2> at the end of the day
[11:17:25] <zeeshan|2> so if it burns your business/house/kills someone
[11:17:33] <zeeshan|2> you'll be 100% liable
[11:17:42] <zeeshan|2> you can try to sue them, but gluck with that :P
[11:17:53] <LeelooMinai> zeeshan|2: For things like that switch, ok, youhave the point, but otherwise I would not be so picky:)
[11:18:07] <zeeshan|2> you can do what you please what your own equipment :)
[11:18:14] <LeelooMinai> Unless you have a lot of money:)
[11:18:21] <zeeshan|2> even if i didnt have the money
[11:18:24] <zeeshan|2> i'd save up
[11:18:31] <zeeshan|2> vs install non approved stuff
[11:18:48] <LeelooMinai> Yes, but it's not always worth saving up just not to buy Chinese - it depends on context
[11:18:51] <zeeshan|2> it's like people installing cheapo chinese tires
[11:18:56] <zeeshan|2> when they explode on you
[11:19:06] <zeeshan|2> at 100 kph
[11:19:12] <zeeshan|2> you'd wish you'd have bought something else :P
[11:19:17] <LeelooMinai> Ok, when it comes to safety, yes, you buy some insurance, but not everything is like that
[11:19:34] <LeelooMinai> I have a lot of Chinese stuff that I like and is fine
[11:19:36] <zeeshan|2> you know what chinese products i've bought?
[11:19:38] <zeeshan|2> dial indicators
[11:19:42] <zeeshan|2> the ones that get abused
[11:19:45] <zeeshan|2> that i can throw away
[11:19:48] <zeeshan|2> vernier calipers
[11:20:11] <zeeshan|2> electric motors (they have certification!)
[11:20:21] <Jymmm> G, PG, PG-13, NC-17, R,
[11:20:23] <zeeshan|2> so it's not like i'm against buying chinese stuff :P
[11:20:52] <zeeshan|2> 12V stuff like relays
[11:21:00] <zeeshan|2> they're also approved :D
[11:21:08] <LeelooMinai> Ok, buy that $50 switch - here:)
[11:21:18] <zeeshan|2> LeelooMinai: at least its 50$!!
[11:21:26] <zeeshan|2> the siemens and eaton and cooper busman are around 300
[11:21:28] <zeeshan|2> ~~ :{
[11:21:39] <zeeshan|2> im pretty sure that 50$ switch is chinese
[11:21:41] <zeeshan|2> just been certified
[11:21:53] <zeeshan|2> btw to answer your question about 100A power
[11:21:55] <zeeshan|2> https://pdf.yt/d/V9KOKhQABiq2cW41
[11:22:05] <zeeshan|2> you can see my power distribution there :P
[11:22:47] <LeelooMinai> That's a lot of stuff you have there:)
[11:22:50] <Jymmm> 88¢ http://www.homedepot.com/p/Leviton-15-Amp-Single-Pole-Toggle-Switch-White-R52-01451-02W/100026991
[11:23:01] <zeeshan|2> i dunno why that bdf isn't showing a dark gray background :/
[11:23:04] <LeelooMinai> O, my pizza beeps - bbl
[11:26:39] <jdh> if Pete shows up, tell him I'm on my way to Florida
[11:26:52] <zeeshan|2> rofl
[11:27:01] <zeeshan|2> are you going diving?
[11:27:04] <jdh> yep
[11:27:07] <zeeshan|2> have fun!
[11:27:11] <jdh> it's dive season.
[11:27:14] <zeeshan|2> still eh!@
[11:27:36] <jdh> probably not up in the frozen arctic
[11:28:01] <zeeshan|2> yea its freezing cold here
[11:28:12] <zeeshan|2> but on monday or tuesday they're saying itll be 13-14 c
[11:28:20] <zeeshan|2> 57 f
[11:28:34] <zeeshan|2> hell of a lot better than 10
[11:28:41] <Jymmm> jdh: dive SEASON? What, the water isn't WET other times of the year?
[11:28:55] <jdh> water is fine, getting out of teh water sucks.
[11:29:32] <Jymmm> jdh: Isn't that what neoprene is for?
[11:29:53] <jdh> nothing worse than a cold wetsuit when the wind blows.
[11:30:00] <Jymmm> =)
[11:30:01] <zeeshan|2> lol
[11:30:07] <jdh> I have a drysuit for water temp < 76F
[11:30:14] <jdh> later
[11:30:40] <zeeshan|2> cya!
[12:06:33] <Jymmm> Propane Tank Meter https://www.kickstarter.com/projects/952047660/tank-utility-keeping-you-warm-all-winter-long
[12:15:15] <Jymmm> I don't get it, how can a hall effect actually METER (10%, 20%... 90%), as opposed you've reached a threshold? https://s3.amazonaws.com/ksr/assets/002/773/567/c4a083791d78c1a23ca3d4c86a5bfa66_large.png?1413842543
[12:15:18] <roycroft> the most accurate way to meter propane is by weight
[12:15:38] <Jymmm> roycroft: you are going to weight a 500lb tank?
[12:15:43] <roycroft> sure
[12:15:48] <archivist> easy
[12:15:56] <Jymmm> roycroft: Uh huh
[12:16:03] <Jymmm> archivist: do tell
[12:16:26] <roycroft> any liquified gas can best be metered by weight
[12:16:30] <archivist> it is the way for bulk tank contents
[12:16:45] <pcw_home> strain gauge in the feet
[12:17:15] <Jymmm> and if the tank is underground?
[12:17:37] <pcw_home> strain gauge in the feet
[12:17:42] <Jymmm> archivist: Are you talking about the hall effect?
[12:17:56] <archivist> no
[12:18:05] <archivist> strain gauges
[12:18:23] <Jymmm> I dont care about thos, it's not gonna happen realistically.
[12:19:35] <roycroft> then do something else and know it's not going to be accurate
[12:19:36] <archivist> hall effect meters rely on an accurate metering rotating device, and if the pressure is wrong they are incorrect
[12:19:45] <pcw_home> anything else is pretty much gawbage
[12:19:56] <roycroft> and especially with a liquified gas the pressure will vary considerably with temperature
[12:21:01] <roycroft> if i take a full co2 tank and set it in my fermenting room at 20c it reads about 700psi
[12:21:15] <roycroft> if i stick it in my lagering freezer, which is 1c, the meter goes down to empty
[12:21:22] <roycroft> yet it's still a full tank
[12:21:24] <roycroft> it varies that much
[12:21:46] <pcw_home> a good mass flow meter might work but is likely a lot more expensive than weighing the tank
[12:22:06] <roycroft> my gas bottles have a tare weight stamped on them
[12:22:14] <roycroft> so i just weigh them to determine how full they are
[12:23:48] <Jymmm> You can get a meter for $200.
[12:24:28] <archivist> it will not be as accurate as weight
[12:25:11] <Jymmm> Maybe not, but the cost has to be worth it.
[12:26:00] <archivist> it is very expensive for a simple pulse counter
[12:27:16] <Jymmm> If it cost $500 for a strain guage and it's accessories, and $200 for a (lets say) 100lb filled backup tank, guess which way I'm going =)
[12:27:31] <roycroft> the other option is to get a second tank, fill it, install a cutover valve, and swith tanks when the first one is empty, then refill
[12:27:43] <roycroft> the second tank can be smaller
[12:28:30] <roycroft> that method is very accurate, but only at two points - when the tank is full and when it is empty
[12:29:03] <Jymmm> Heh, funny thing... I have 5x20lb tanks right now.
[12:29:12] <roycroft> i have a bunch of 20lb tanks
[12:29:21] <roycroft> and my method is to use one until it's empty then swap
[12:29:30] <roycroft> and when i get a bunch of empties i refill them all
[12:31:51] <archivist> I go without heating
[12:32:10] <roycroft> i go without beermaking
[12:32:14] <roycroft> so just as important :P
[12:42:48] <_methods> i drink a lot of it
[12:54:02] <CaptHindsight> how does that tank meter measure the level in those tanks?
[12:54:12] <CaptHindsight> the one on kickstarter
[12:54:29] <roycroft> with a flowmeter of some sort
[12:54:34] <roycroft> so, inaccurately :)
[12:55:10] <CaptHindsight> the video makes it look like it clips onto your existing mete
[12:55:14] <CaptHindsight> meter
[12:56:02] <CaptHindsight> I don't any specs on accuracy
[12:56:30] <CaptHindsight> so if they don't have any, then it's somewhere between Full and Empty
[12:57:17] <CaptHindsight> no specs, no claims
[12:58:19] <CaptHindsight> does their meter spin?
[12:58:38] <CaptHindsight> that might explain the hall sensor
[12:59:16] <_methods> don't most propane companies put telemetry on their tanks for refills anyways?
[12:59:33] <Rab> Looks like some meters have remote takeoffs which use a hall effect sensor to measure the position of the needle.
[12:59:57] <CaptHindsight> it might assume that you enter in the assumed weight of the propane tank
[13:00:05] <roycroft> the propane companies around here don't want you knowing how full the tank is
[13:00:16] <roycroft> they charge by the gallon + a truck roll charge
[13:00:17] <Rab> How proportionality is derived from the hall effect, I don't know. But I don't think it's a flow meter.
[13:00:27] <CaptHindsight> heh, yeah sounds about right
[13:00:39] <roycroft> if you're always guessing how much is left you're going to order more truck rolls than necessary to be sure you don't run out
[13:00:42] <CaptHindsight> just collect money, all else is secondary
[13:01:27] <roycroft> welcome to america
[13:01:56] <CaptHindsight> working out well isn't it
[13:05:25] <roycroft> my propane guy just called this morning, as a matter of fact, wanting to top off the tanks at my fiber huts
[13:05:39] <roycroft> they are probably 3/4 full, but i don't know, so i'm sending him out to do it
[13:33:49] <Topy44> hi
[13:34:21] <Topy44> i am working on a board that among other things will control stuff like the air assist pump, cooling system and exhaust fan of a laser cutter
[13:35:17] <Topy44> it is based on an atmel µc with usb port, acting as a virtual serial device, and should communicate with linuxcnc through a userspace component
[13:35:42] <andypugh> Sounds potentially useful, and you can probably re-use the existing Arduino driver.
[13:36:26] <andypugh> http://emergent.unpythonic.net/01198594294
[13:36:47] <Topy44> however i don't fully understand the linuxcnc structure - most importantly, what a "component" actually is in this context :)
[13:37:03] <Topy44> oh, that is useful, yes
[13:38:59] <andypugh> A “component” is a program file that is loaded on-demand by the HAL file and ommunicates with other parts of the software via HAL pins.
[13:39:33] <andypugh> You can compile new components without having to re-compile LinuxCNC.
[13:40:05] <andypugh> The tool for compiling components is http://www.linuxcnc.org/docs/2.7/html/hal/comp.html
[13:40:13] <Topy44> i have seen that, yes
[13:40:36] <andypugh> (Or you can write a Userspace compoenent in Python if you prefer)
[13:40:53] <Topy44> yes, i might prefer writing it in python, not sure yet
[13:40:53] <Loetmichel> *ha* my bottle of lahroaig cask strength has finally reached the local delivery center... tomorrow evening i will be sipping on a GREAT whiskey ;-) (and dhl tracking is a nice invention for the impatioent ;-)
[13:41:20] <Topy44> Loetmichel: hah. small world. why am i not surprised to see you here. :)
[13:42:51] <Loetmichel> Topy44: because you know i use linuxcnc?
[13:43:01] <Topy44> Loetmichel: i actually didn't know, no
[13:43:05] <andypugh> Loetmichel: Have you tried Highland Park? I rather like that.
[13:43:21] <Topy44> andypugh: so the way i understand it... i let my component code loop indefinitely and update those "pins"? or does linuxcnc call it on a regular basis?
[13:43:32] <Loetmichel> andypugh: no, only other schottish name i can remember is a glenfiddich (sp?)
[13:43:47] <andypugh> A userspace component loops. A realtime component is polled every thread.
[13:43:50] <Loetmichel> that i have been drinking the last yeras in very small quantitys
[13:44:10] <Topy44> andypugh: aaah, that helps a lot, thanks
[13:44:17] <Loetmichel> ... until wife gifted the half full bottle to my brother in law
[13:44:25] <Loetmichel> ... still mad at her for that
[13:44:25] <andypugh> http://highlandpark.co.uk
[13:47:14] <andypugh> For a whiskey that really does have a distinctively different taste: http://www.malts.com/index.php/en_gb/Our-Whiskies/Talisker/Introduction
[13:47:42] <andypugh> I just recieved a bottle of Bourbon in payment for some motorcycle parts.
[13:50:29] <roycroft> i'm pretty sure i heard of a new distillery opening on the isle of skye
[13:50:43] <roycroft> i've never had talisker - i shall look for it
[13:51:04] <roycroft> it sounds expensive though
[13:51:41] <CaptHindsight> it's peaty
[13:51:55] <roycroft> i like laphroaig
[13:51:56] <roycroft> so
[13:52:04] <Rab> I know someone who was crazy about Talisker, and it was expensive.
[13:52:05] <CaptHindsight> not like Ardbeg but peaty for a non-islay
[13:52:13] <Rab> Tasted OK, but I'm not a whiskey drinker.
[13:52:25] <roycroft> talisker is whisky, not whiskey :)
[13:52:39] <roycroft> whiskey is from ireland
[13:53:24] <Rab> I'm from Texas, such subtleties are far beyond me.
[13:53:48] <andypugh> I saw my error and cringed but hoped I would get away with it.
[13:54:14] <roycroft> i'm not sure why
[13:54:17] <CaptHindsight> talisker 10 yo is ~$60 750ml
[13:54:34] <roycroft> but scots and canadians make whisky
[13:54:40] <roycroft> irish and usians make whiskey
[13:55:18] <roycroft> and i'm not sure how that stuff from the new distillery in london is spelled
[13:55:32] <roycroft> england hasn't produce whisk[e]y in a long long time until just now
[13:55:38] <andypugh> Talisker is £30 a bottle here
[13:56:04] <roycroft> i guess we'll find out in a decade or so how it's spelled
[13:56:24] <andypugh> Laphroig is £29, Highland Park also £33.
[13:57:10] <CaptHindsight> how much for Ardbeg?
[13:58:14] <andypugh> £47
[13:58:27] <CaptHindsight> huh, lower here
[13:59:20] <CaptHindsight> at least it the real stuff
[14:00:28] <andypugh> of course, you can pay more: http://www.masterofmalt.com/whiskies/ardbeg/ardbeg-1974-provenance-with-presentation-box-whisky
[14:01:34] <CaptHindsight> all those special packages and special casks
[14:01:58] <CaptHindsight> many are not anything special but become collectors items
[14:02:34] <Loetmichel> roycroft: talisker is nice
[14:03:00] <Loetmichel> things i would want to avoid is anything with "dimple" in name ;-)
[14:03:14] <CaptHindsight> Loetmichel: did your bottle ever arrive?
[14:03:22] <Loetmichel> it will tomorrow
[14:03:32] <Loetmichel> says the dhl tracking
[14:03:35] <CaptHindsight> "dimple"?
[14:04:25] <Loetmichel> http://www.amazon.de/Dimple-15-Years-Whiskey-700/dp/B001P4YYOI <- tastes like the dish water imho
[14:04:26] <andypugh> http://www.masterofmalt.com/whiskies/haig-dimple-15-year-old-whisky/?srh=1
[14:05:13] <Topy44> sorry for interrupting your whiskey discussion here (as a not-particularly-whiskey-loving actual irish person :) quick question: since userspace components run, well, in the userspace... that means i should be able to test them with a simulator setup in a virtual machine, right?
[14:05:13] <andypugh> This is, however, a really nice bottle: http://www.masterofmalt.com/whiskies/haig/haigs-dimple-royal-decanter-pewter-1970s-whisky/?srh=1
[14:05:24] <andypugh> Yes
[14:05:28] <Topy44> with the userspace component connected to a usb device hooked up to the virtual machine
[14:06:24] <andypugh> (I actually run a realtime kernel in a VM and ignore the fact that the latency is horrible, things still work well enough for testing)
[14:06:40] <Topy44> ok great
[14:07:29] <Topy44> so the goal for tonight is: get an led on an arduino to blink from linuxcnc on a virtual machine. :) if that works, it should also work with my real board
[14:11:39] <Rab> Topy44, what type of virtualization? VMware, VirtualBox, etc?
[14:11:47] <Topy44> virtualbox
[14:12:12] <CaptHindsight> Topy44: how are you connecting the *duino to the PC?
[14:12:25] <Rab> Topy44, I'm interested to know how that turns out. Passthrough for the hardware might be a challenge.
[14:12:53] <Topy44> CaptHindsight: just the usual way, hook up the device and tell virtualbox to connect it?
[14:13:06] <CaptHindsight> PC---> USB ---> *duino
[14:13:13] <Topy44> its a leonardo-clone, so no ftdi chip
[14:13:43] <Topy44> its got an atmega32u4 or something among those lines on it, so it has a real usb port (which is what i'll be using for my board too)
[14:14:01] <Topy44> (i don't really use arduino stuff much, but this should do just fine as a test platform)
[14:25:38] <CaptHindsight> ever try Amrut the Indian single malt?
[14:31:08] <andypugh> No
[14:32:24] <CaptHindsight> I've never heard of anyone liking it so far, except for a review :)
[14:33:45] <andypugh> It’s not cheap
[14:34:33] <andypugh> This version gets a good review: http://www.masterofmalt.com/whiskies/amrut-fusion-whisky/?srh=1
[14:43:12] <tjtr33> re: siingle malts. i have no taste for them but if i visit a friend who does, and want to bring a gift... whats good and not 'peculiar' ? http://www.worlddutyfree.com/exclusives/exclusive-malt-whiskies.html
[14:46:05] <andypugh> Buying for myself it would be Talisker, for someone else prbably Laproaigh or Bunnahabhain
[14:46:44] <andypugh> (The latter mainly for the unspellable name).
[14:47:17] <tjtr33> heh i'm from a welsh line, so unspeakable names appeal to me
[14:47:20] <tjtr33> thx
[14:47:39] <andypugh> (Actually that Bunnahanhain sounds a bit fierce)
[14:48:20] <CaptHindsight> http://www.auchentoshan.com/ Gesundheit!
[14:48:45] <tjtr33> the guy challenged me at a dinner with XO ( i dunno but guess its perfumed cognac ) tasted so bad i gulped it. finished 2 bottles, then exploded
[14:49:43] <andypugh> Hmm. Perhaps you should stick to cheap blended whisky then.
[14:49:44] <CaptHindsight> VS, VSOP and then XO is just older
[14:50:10] <tjtr33> tastes foul, gimme Tito's vodka, no problem
[14:50:38] <tjtr33> thx for the tips
[14:50:45] <CaptHindsight> if you're just drinking for effect
[14:51:19] <tjtr33> no i like the taste
[14:51:21] <CaptHindsight> but I often see great stuff being slammed like it's a frat house
[14:51:55] <tjtr33> my taste is different , thats why i dont like whiskies
[14:56:24] <Aero-Tec2> I need to do a manual move in mid run
[14:56:38] <Aero-Tec2> any ideas as to how to do that?
[14:56:58] <Aero-Tec2> I did a M0 and tried to move but could not
[14:57:19] <cradek> you can't
[14:57:28] <cradek> just abort and move, then use run-from-line to restart there
[14:57:51] <Aero-Tec2> ok cool
[14:57:54] <Aero-Tec2> thanks
[15:26:59] <Rab> Can you do a manual jog during feed hold?
[15:27:44] <renesis> you mean when the cycle is paused?
[15:28:43] <Rab> yeah
[15:29:59] <renesis> nope
[15:30:05] <Jymmm> Interesting, my lil 2yo 4000BTU heater sucked propane faster than it could convert it gas from a 20lb tank last night
[15:30:19] <Jymmm> s/it/to/
[15:32:05] <renesis> rab: are you trying to do a tool change?
[15:32:49] <roycroft> if the tank was cold i could see that
[15:33:36] <Jymmm> roycroft: It wasn't THAT cold (maybe 50F) and half full. I originally thought it emptied out.
[15:33:59] <roycroft> at that temperature it should not have happened
[15:34:32] <Jymmm> Nope, maybe in the 40ies,
[15:34:38] <Jymmm> 40's
[15:38:32] <roycroft> i run a 60,000 burner on my brew system off a 20# tank
[15:38:43] <roycroft> in the winter i bring the tank in overnight before brew day
[15:38:52] <roycroft> but i've never had a problem
[15:39:04] <Loetmichel> Jymmm; i have seeen 11kg tanks ice over in mid summer with a IR heater on top of it
[15:39:30] <Jymmm> Tank is AUG-2000, not sure if that has anythign to do with it (OPD valve)
[15:39:52] <Jymmm> Loetmichel: Yeah, I have to watch that when I'm using 1LB tanks on this heater.
[15:40:45] <Jymmm> This is the first in 3years I've seen it "gas out" and this is the LOW (4000BTU) setting too, not even the HI (9000 BTU) settting which I might expect kinda
[15:41:14] <roycroft> i wonder if there's a problem with thank itself
[15:41:17] <roycroft> or its valve
[15:41:20] <roycroft> tank
[15:41:28] <roycroft> or perhaps your regulator
[15:41:35] <roycroft> i had to replace a regulator not long ago
[15:41:39] <Rab> renesis, see Aero-Tec2's question.
[15:41:47] <Jymmm> That's okey though. I got this tank for free and it was full. When it's empty, I'll go exchange the tank for a new one.
[15:42:36] <roycroft> around here it's much cheaper to refill tanks than to go to tank exchanges
[15:42:46] <renesis> rab: oh, cradek already answered so is officially answered
[15:42:52] <roycroft> but when the tank needs to be recertified it's cheaper to exchange it than to pay the recertification fee
[15:43:10] <Jymmm> I only exchange EXPIRED tanks ($19.63), I refill the rest.
[15:43:19] <roycroft> right
[15:43:32] <Loetmichel> http://1.bp.blogspot.com/-Vk7hdbXODi4/TeLA8lM1y1I/AAAAAAAAAts/OSoj5xQuHHA/s1600/Gas.jpg <- like this
[15:43:38] <roycroft> i still get pre-olp tanks off cl for $5 upon occasion
[15:43:53] <roycroft> i just use up any gas that might be in them and take them to a tank exchange
[15:43:55] <Jymmm> why PRE opd?
[15:44:30] <Jymmm> Loetmichel: Yep, you suck too fast! lol
[15:44:32] <roycroft> because they're cheaper
[15:44:47] <roycroft> i can get them for $5
[15:44:49] <Jymmm> I get OPD tanks for cheap/free off CL all the time.
[15:45:10] <roycroft> they go for almost retail on cl here
[15:45:13] <Jymmm> ppl moving giving away their free rust bbq, free tank included =)
[15:45:16] <roycroft> $25-$30
[15:45:38] <Loetmichel> Jymmm: nice one is that that is self-regulating: if the tank ices over the flame will go off because it dosent get gaseous propane any longer
[15:45:51] <Loetmichel> ... so the tank will deice ;-)
[15:46:03] <Jymmm> Loetmichel: YAY PHYSICS!!!
[15:46:29] <Loetmichel> you just have to restart the burner which is switched off by the safety valve
[15:46:44] <Jymmm> Loetmichel: I like your tanks, bottom, but I like our tanks ring
[15:46:59] <Loetmichel> ring?
[15:47:33] <Jymmm> Loetmichel: protects the valve http://upload.wikimedia.org/wikipedia/commons/f/fe/Propane_tank_20lb.jpg
[15:47:50] <Jymmm> the C Ring
[15:47:57] <Jymmm> slash handle
[15:48:13] <Loetmichel> you see the recess below the valve on the german tank?
[15:48:34] <Jymmm> yeah
[15:49:30] <Loetmichel> thats where these hoods clip in: http://www.gasecenter-eulitz.de/s/cc_images/teaserbox_25003764.jpg?t=1401283577
[15:49:47] <Jymmm> ah
[15:50:22] <Jymmm> Loetmichel: Eh, something to lose
[15:50:31] <Loetmichel> not really
[15:50:34] <andypugh> UK bottles combine both: http://www.calor.co.uk/13kg-propane-gas-bottle.html?gclid=COCu4MKQisICFWXHtAodWicARQ
[15:50:48] <Loetmichel> bcause you cant get the tanks refilled/exchanged when you loose the hood
[15:51:25] <Jymmm> Loetmichel: and that would suck big time if it was misplaced
[15:51:58] <Jymmm> I did find that US 20lb tanks fir PERFECTLY inside milk crates to prevent tipping over
[15:52:05] <Jymmm> fit*
[15:52:15] <Loetmichel> weh have the ringed wone shere, too
[15:52:18] <Loetmichel> http://www.reisezaepfchen.de/Diesunddas/Flohmarkt/Gasflaschen.JPG
[15:52:40] <Loetmichel> ... but only on bottles for engines (forklift, etc)
[15:53:02] <Loetmichel> *ones here*
[15:53:23] <Jymmm> http://media.charlotteobserver.com/smedia/2014/05/14/10/49/QHKix.Em.138.jpeg
[15:53:49] <Jymmm> instead of this shit http://vogeltalksrving.com/wp-content/uploads/2013/09/TailGater-Strap.jpg
[15:54:35] <Loetmichel> the biggest tank i had explode on me was a half pound butane cartridge for these bunsen burners
[15:54:51] <Jymmm> how did it explode?
[15:54:56] <Loetmichel> ... which i had in my Cylon costume to power the litttle 0,99cc engine
[15:55:13] <Loetmichel> i welded something in the backpack and got the cartridge to hot ;-)
[15:55:38] <Red70sShow> Loetmichel: <-- DUMBASS
[15:55:42] <Loetmichel> right
[15:56:11] <Loetmichel> ... the last steel splinters grew out a few months later, tho
[15:56:18] <Jymmm> Loetmichel: I use those 1/2lb brutane cans you asshole! Don't scare me like that =)
[15:56:30] <Loetmichel> and as i am wearing glasses my eyes got no damage at all
[15:57:12] <Loetmichel> ... was quite a bang and a fireball
[15:57:18] <Jymmm> My heater (kid not included) http://www.ifish.net/gallery/data/500/medium/LarkenCrashed.jpg
[15:57:34] <Jymmm> Wait, that's the BIG one.
[15:58:23] <Jymmm> Mr Heater Portable Buddy (this is mine) http://professional-power-tool-guide.com/wp-content/uploads/2011/09/mr-heater-buddy-3.jpg
[15:58:27] <FinboySlick> Jymmm: She's not that big, you meanie.
[15:58:34] <Jymmm> the Big Buddy is the dual
[15:58:52] <Jymmm> FinboySlick: Hey, they grow p ya know! =)
[15:58:57] <Jymmm> up*
[16:00:11] <FinboySlick> There's a happy stage between "poop/puke all the time" and "can I get 40 bucks and the car keys tonight" stages.
[16:01:12] <Jymmm> FinboySlick: The proper response is "You are not leaving this home till you are 30yo young lady"
[16:04:17] <Loetmichel> Jymmm: i had the daugherts of my boss around at last job
[16:04:20] <Loetmichel> 3 of them
[16:04:33] <Loetmichel> age 7, 9, 13
[16:04:41] <Loetmichel> ... THAT was an annoance...
[16:04:57] <Loetmichel> was lately there and met the oldes one... now 17teen...
[16:04:58] <Jymmm> lol
[16:05:12] <Loetmichel> oh by... that girl was changed...
[16:05:40] <Loetmichel> and i DONT envy my ex-boss...
[16:05:54] <Loetmichel> she was EXACTLY in that "40 buchs and the car keys" stage ;-)
[16:07:25] <Jymmm> Loetmichel: That's the not the problem. the problem is when she has learned that she can pull out th epuppy dog eyes and wrap daddy around her finger =)
[16:07:55] <Loetmichel> hrhr, yeah, thats what i meant: "i dont envy him" ;-)
[16:08:03] <Loetmichel> more like "i pity him"
[16:08:13] <Jymmm> haha
[16:09:16] <Loetmichel> she once got me so angry that i grabbed her at the hips and carried her out of the workshop
[16:09:31] <Loetmichel> ... a few weeks later she was teasing me again...
[16:09:49] <Jymmm> Loetmichel: Two words... Duct tape.
[16:09:53] <Loetmichel> <- " shall i geo up and carry you out again?"
[16:10:26] <Loetmichel> her: "no, thanks, i am wuiet already, i still have your 10 fingers as blue marks on my hips"
[16:10:29] <Loetmichel> <-"ups"
[16:12:10] <Loetmichel> after that it was usually enough to show her my hands and point to her hips and she quit teasing ;-)
[16:12:21] <Jymmm> lol
[16:12:22] <Loetmichel> quite useful that mishap ;-)
[16:12:31] <SpeedEvil> The correct response is 'you wouldn't have any bruises if you lost weight'
[16:12:44] <Loetmichel> oh, she was only 45kg
[16:12:59] <SpeedEvil> bruises lasting that long are not a good sign then
[16:13:00] <Loetmichel> and i was not THAT angry to destroy her self esteem forever
[16:13:10] <Jymmm> Besides, never scorn any female at any age, especially the bosses daughter =)
[16:13:16] <SpeedEvil> yeah - not at all funny in real life
[16:13:20] <Loetmichel> s/weeks/days
[16:13:23] <SpeedEvil> ah
[16:14:11] <Loetmichel> Jymmm: i am WAY to old for her
[16:14:17] <Loetmichel> besides: i am married
[16:14:36] <Jymmm> Loetmichel: doesn't matter. A scorned female is a scorned female.
[16:14:41] <Loetmichel> <- had to google scorn first
[16:14:48] <Jymmm> even if no relations exist.
[16:15:05] <Jymmm> they NEVER forget.
[16:15:16] <Jymmm> N E V E R
[16:15:26] <Loetmichel> oh, i dint mean te4asing in a sexual way.
[16:15:38] <Jymmm> Loetmichel: I know you didn't. Neihter did I
[16:15:50] <Loetmichel> i meant teaing in a taunting way
[16:15:56] <Jymmm> Yep
[16:16:01] <Jymmm> I totally understand
[16:17:28] <Loetmichel> besides : the 4 children (htere was a boy of 4 in that bunch) knew that i had the oficial grant from her father to use "corporal punishment" to get them in line...
[16:17:34] <Jymmm> crap, this is gonna suck.... I need to laser cut a star to remove the triangles, ADN a circle at it's base that I need to keep and maintain tight tolerance *sigh*
[16:18:04] <Loetmichel> ... not i would ever do that but i think boss said that in their presence exactly for that reason: to give me some leverage... knowing his kids...
[16:18:19] <Jymmm> good for you
[16:18:19] <Loetmichel> :-)
[16:19:58] <Loetmichel> http://www.cyrom.org/hajo/09_01_09.avi <- a work day there
[16:20:37] <Loetmichel> somewher ein there are my boss (red sweater) me(black shirt) his wife (red jacket) and his kids, alt least a few of them
[16:23:38] <Deejay> gn8
[16:24:19] <Jymmm> FARK FARK FARK FARK FARK!!!!
[16:24:26] <Loetmichel> fark?
[16:24:32] <Deejay> are you ok, Jymmm?
[16:25:03] <Jymmm> No, what apears in the drawing is NOT as big as you think it is!
[16:26:24] <Jymmm> 26 point star, and I needed each point to be 0.100", turned out to be 0.006"
[16:27:46] <Jymmm> I *THINK* I still have enough roof/tolerance left for everything else, but not sure yet.
[16:27:53] <Jymmm> room*
[17:04:43] <andypugh> Probably the final entry in the Ner-a-Car blog. http://bodgesoc.blogspot.co.uk/2014/11/the-last-bits-and-pieces.html
[17:04:55] <zeeshan|2> aw
[17:05:17] <zeeshan|2> congrads :P
[17:05:39] <zeeshan|2> andypugh: im giving up on that speed selector board
[17:05:50] <zeeshan|2> i spent most of all night yesterday reverse engineering the pcb
[17:05:53] <zeeshan|2> and drawing a schematic
[17:05:56] <zeeshan|2> still makes no sense to me
[17:06:12] <andypugh> Doesn’t it just output 6 signals?
[17:06:19] <zeeshan|2> no its not that simple
[17:06:58] <zeeshan|2> https://pdf.yt/d/jzma-yG5QEkpSgsD
[17:07:01] <andypugh> Ah, in that case I suggest removing components until it is that simple and then doing the clever stuff in HAL.
[17:07:25] <zeeshan|2> the transistors might be upside down
[17:07:28] <zeeshan|2> in that diagram
[17:07:42] <renesis> well
[17:07:46] <zeeshan|2> my problem is i have no clue where the vcc goes to
[17:07:47] <renesis> thats a big deal =\
[17:08:15] <zeeshan|2> i can see that pin 1-4 11-12 are something to do with the hall sensors.
[17:08:16] <renesis> zeeshan|2: retrace starting from the vreg
[17:08:40] <zeeshan|2> ren when i put ohmmeter betweren vreg input to pin 5
[17:08:42] <zeeshan|2> i got continuity
[17:09:02] <zeeshan|2> when i measure resistance i get 0-1 ohm
[17:09:18] <zeeshan|2> when i measure resistance for vreg out to pin 5, i get like 50k ohm
[17:09:26] <zeeshan|2> which makes 0 sense.
[17:09:30] <renesis> i wouldnt use continuity testing to trace this
[17:10:27] <andypugh> Maybe the circuit makes sense to PCW? (who does seem to understand electronics)
[17:10:29] <renesis> im not sure, but continuity test might beep through a diode
[17:11:35] <renesis> so if pin5 was ground, and you probed vin on the vreg, theres a 50% change tyoure seeing continuity through the reverse biased diode across the vreg input
[17:12:08] <zeeshan|2> ok ill retrace manually
[17:13:01] <renesis> yeah my fluke is showing a 1n914 as like 340R
[17:13:12] <renesis> i dont think itll beep until <10R
[17:13:41] <renesis> anyway, check ohms when you see a beep
[17:13:52] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15210012634/
[17:13:53] <renesis> 9R is not the same as 0R in a lot of contexts
[17:13:59] <zeeshan|2> is bottom most pin input or output for the vreg
[17:13:59] <renesis> like working on speakers =\
[17:14:08] <zeeshan|2> http://fixit-service.kz/files/L7812CV.pdf
[17:14:14] <zeeshan|2> from what im grasping from page 2
[17:14:22] <zeeshan|2> looks like ouput
[17:14:36] <andypugh> Alternatively, ignore _how_ the PCB works and see what the output pins do when you hold a magnet near each switch.
[17:14:44] <zeeshan|2> andypugh: i did
[17:14:46] <zeeshan|2> nothing happens
[17:14:55] <zeeshan|2> it might be in "crap mode"
[17:15:07] <zeeshan|2> because this board experts to be hooked up to a hall microswitch
[17:15:13] <zeeshan|2> which monitors spindle speed
[17:15:21] <zeeshan|2> so when the spindle isnt spinning, the outputs work
[17:15:32] <zeeshan|2> but im not sure where the sensor wires up to
[17:15:33] <andypugh> Maybe
[17:17:42] <zeeshan|2> fuck
[17:17:45] <zeeshan|2> sorry for the language
[17:17:50] <zeeshan|2> but i think pin 10 is VCC.
[17:17:56] <renesis> pin 3 is output, pin 2 is ground
[17:18:26] <zeeshan|2> which means i musta drawing the schematic wrong.
[17:18:46] <renesis> you put 24V on the output
[17:18:59] <renesis> and you saw a diode drop at the other end of the vreg
[17:19:25] <zeeshan|2> yuea no wonder why my vreg wouldnt show 12v
[17:19:30] <zeeshan|2> i had 24v going to the bloody output
[17:19:51] <zeeshan|2> if you look at the schematic
[17:19:54] <zeeshan|2> why is there a resistor
[17:19:58] <zeeshan|2> er nm
[17:21:17] <zeeshan|2> its a bit weird
[17:21:34] <zeeshan|2> that pin 10 has a resistor at the input side of the v-reg.
[17:21:46] <renesis> what size resistor
[17:21:53] <zeeshan|2> says 33R on it
[17:21:56] <zeeshan|2> its a 7W resistor
[17:22:14] <renesis> and with a known max load current, you can use a resistor to pull power away from the vreg without dropping it out
[17:22:24] <renesis> yeah, thats what that resistor is doing
[17:22:40] <renesis> the resistor is probably cheaper than a heatsink for the 7812
[17:22:43] <zeeshan|2> i hope i didnt fry crap
[17:22:47] <zeeshan|2> but hooking up 24v to pin 4
[17:22:48] <renesis> get away with the pcb sink on the other side
[17:22:49] <zeeshan|2> pin 5
[17:22:50] <zeeshan|2> lol
[17:23:10] <renesis> do you have data for the hall sensors?
[17:23:20] <renesis> theyll have abs max voltage in the first couple pages
[17:23:29] <zeeshan|2> 24v is abs max voltage
[17:23:36] <zeeshan|2> for most of the components except 4528bdc
[17:23:41] <renesis> what kind of supply are you using
[17:23:42] <zeeshan|2> that specifies 18v
[17:23:44] <zeeshan|2> smps
[17:23:49] <renesis> yeah you prob blew that
[17:23:55] <zeeshan|2> the psu?
[17:23:59] <zeeshan|2> psu is fine
[17:23:59] <renesis> no the opamp
[17:24:01] <zeeshan|2> oh
[17:24:08] <zeeshan|2> it was stupid hot to touch
[17:24:11] <zeeshan|2> i knew something was up!
[17:24:51] <zeeshan|2> lets see what happens when i hook it up to pin 10 now :P
[17:25:52] * Jymmm hands zeeshan|2 the fire extinguisher
[17:27:20] <zeeshan|2> yay
[17:27:23] <zeeshan|2> im getting 12v at the reg now
[17:28:02] <Topy44> right, it works. that was surprisingly painless.
[17:28:41] <Topy44> that is: controlling stuff on a microcontroller from linuxcnc through a python userspace component
[17:28:48] <andypugh> The HAL component?
[17:29:01] <Topy44> yeah
[17:29:18] <andypugh> That was pretty quick
[17:30:18] <Topy44> i actually watched some tv in between :) but yeah, just a few lines of python code and a basic "flick a pin if you receive this byte" firmware
[17:30:28] <tjtr33> usea DIA you takeadee fotos, you putta fotos inna layers, you putta da symbols onna da new layer, you connecta da dots you getta da schematic that you canna re-arrange :)top foto http://ibin.co/1hwKURoZ1A2b bottom foto http://ibin.co/1hwL1DhMjCRn components http://ibin.co/1hwLIiNJg8kj nets http://ibin.co/1hwLYKFcmuu2 schema http://ibin.co/1hwLmghGgtus
[17:30:29] <tjtr33> http://ibin.co/1hwLYKFcmuu2
[17:30:32] <Topy44> didn't expect it to just...work
[17:31:22] <Topy44> i'll go back to designing the hardware, just wanted to go sure this works before i make a board
[17:33:07] <CaptHindsight> if zeeshan|2 didn't hate electronics so much he could make the board more simple
[17:34:49] <Topy44> tjtr33: wtf is that?
[17:34:52] <zeeshan|2> lol
[17:34:53] <Topy44> one hell of an ugly layout :)
[17:35:15] <CaptHindsight> they actually sense the position of the knobs or gear selectors with hall sensors?
[17:35:28] <tjtr33> the board IS ugly, but you can move the nets around in DIA and make it pretty
[17:35:41] <Topy44> ah, its just a reconstruction of the board to reconstruct the layout of a physical board you have?
[17:35:55] <tjtr33> Topy44, did you talk to arduino with Hal?
[17:36:02] <Topy44> tjtr33: yes
[17:36:14] <tjtr33> yes, complicated boards would be harder to understand
[17:36:39] <Topy44> what is that board?
[17:36:54] <tjtr33> Topy44, MIT's Inventor App is fun to control arduino with android
[17:37:00] <CaptHindsight> zeeshan|2: where is the picture of those speed selectors?
[17:37:06] <tjtr33> Topy44, stupid dc power supply
[17:37:09] <Topy44> right
[17:37:26] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15536981611/
[17:37:40] <Topy44> i don't really use arduino stuff. i used one because i had one flying around and it happens to use the same µC i am using on my board, so it made a good quick and dirty test platform.
[17:37:53] <zeeshan|2> i tried the 24v dc shock test
[17:37:57] <zeeshan|2> its just like 12v
[17:37:59] <zeeshan|2> doesnt hurt :P
[17:38:23] <zeeshan|2> my resistance is too much :]
[17:38:33] <zeeshan|2> so it looks like even with the correct vcc and ground
[17:38:37] <zeeshan|2> the sensors dont switch.
[17:39:06] <andypugh> Maybe your magnet is too strong, too weak, or the wrong monopole?
[17:39:19] <zeeshan|2> andypugh: btw i looked at the motors closest
[17:39:21] <zeeshan|2> *closely
[17:39:29] <zeeshan|2> there are no magnets in there?
[17:39:33] <zeeshan|2> i cant stick any metal to em.
[17:39:53] <andypugh> Probably induction motors of some sort.
[17:40:01] <andypugh> Maybe even shaded-pole
[17:40:23] <zeeshan|2> so its picking up the mag field of the motors?
[17:40:27] <andypugh> Until recently _most_ motors had no permanent magents in them
[17:40:38] <zeeshan|2> so i mean for hall sensing
[17:40:48] <andypugh> No, it is picking up the magnets on the internally-toothed gears
[17:40:58] <zeeshan|2> i cant stick metal to it?
[17:41:07] <zeeshan|2> oh.
[17:41:12] <zeeshan|2> hm......
[17:41:17] <CaptHindsight> counts gear teeth as they go by by changing state
[17:41:24] <andypugh> (I asume those lumps are magnets)
[17:41:37] <zeeshan|2> ha
[17:41:42] <zeeshan|2> those things are prolly magnets
[17:41:45] <zeeshan|2> i was thinking it was inside the gear.
[17:41:47] <zeeshan|2> lemme go check
[17:41:56] <zeeshan|2> gear = spline
[17:42:27] <CaptHindsight> yeah splines vs teeth
[17:42:31] <CaptHindsight> but you get the point
[17:42:40] <CaptHindsight> high and low points
[17:43:02] <CaptHindsight> Hall sense On or OFF
[17:43:08] <zeeshan|2> im clearly blind
[17:43:08] <CaptHindsight> high low
[17:43:10] <zeeshan|2> andypugh: you are right
[17:43:12] <zeeshan|2> those are magnets.
[17:44:22] <andypugh> And I guess if you turn the shafts by hand so that the magnets align with the hall sensor positions you will get various gears
[17:50:49] <zeeshan|2> yes
[17:51:17] <zeeshan|2> the cylindrical magnet's ends are parallel with the hall sensors
[17:51:21] <zeeshan|2> im about to try one
[17:51:25] <zeeshan|2> i marked it and took one off
[17:55:23] <zeeshan|2> sigh
[17:55:25] <zeeshan|2> nothing
[17:56:04] <andypugh> Maybe the circuit pulls-down the output pin rather that setting it high?
[17:56:15] <zeeshan|2> im measuring
[17:56:20] <zeeshan|2> right at the hall switch
[17:56:25] <zeeshan|2> at its output pin
[17:56:28] <zeeshan|2> it should be changing?
[17:56:36] <zeeshan|2> measuring hall output to ground
[17:56:52] <andypugh> I don’t know, I wouldn’t bet on it with the rest of the board unconected.
[17:57:10] <zeeshan|2> i really feel like its something to do wit hthe spindle speed sensor
[17:57:14] <tjtr33> when S pole aproaches it? theres 3 kinds, switch, latch and proportional, maybe you have latch type, and its waiting for opposite end of magnet to release ( or it blowed up real good )
[17:57:15] <zeeshan|2> if its disconnected, its in limp mode
[17:57:38] <andypugh> Was it all working before?
[17:57:51] <zeeshan|2> yes apparently this was a working machine
[17:57:57] <zeeshan|2> so far i havent found any evident thats its bad
[17:58:03] <zeeshan|2> (the machine)
[17:58:16] <zeeshan|2> one important thing to note is
[17:58:26] <zeeshan|2> pin 5 goes to collector all the transistors
[17:58:36] <andypugh> Have you looked at the datasheet for the sensors? Is there a typical circuit?
[17:58:52] <zeeshan|2> http://www.datasheet-pdf.com/datasheetdownload.php?id=630733
[17:58:55] <zeeshan|2> this is all i see
[17:59:14] <andypugh> (I have to look up what the collector even is, so my helpfulness is likely to be limited.)
[17:59:28] <zeeshan|2> im on the same boat
[18:01:03] <zeeshan|2> im gonna try hooking up the external speed sensor and see what happens
[18:01:14] <zeeshan|2> fire extinguisher is ready
[18:01:48] * Jymmm hands zeeshan|2 the explosives and runs like hell!
[18:01:59] <zeeshan|2> lol
[18:03:01] <Jymmm> Actually, that gave me a great idea!
[18:04:39] <tjtr33> (curmudgeon mode) did a _salesman_ tell you it was working? or did you see it shift gears. if you removed the sensor and cant get it to trigger, its fubared or you got the wrong wiring.
[18:06:31] * LeelooMinai finished installing limit switches today, finally
[18:06:57] <tjtr33> Sprague! woof that is old, from the uln sprague driver days (80's)
[18:07:25] <LeelooMinai> I did not really trust my old, setup.
[18:07:37] <LeelooMinai> I have them like this now: https://www.flickr.com/photos/100017731@N03/15650776467/
[18:07:57] <LeelooMinai> https://www.flickr.com/photos/100017731@N03/15834043971
[18:08:56] <LeelooMinai> And made this little box so I can disconnect the cable from the CNC: https://www.flickr.com/photos/100017731@N03/15837471732
[18:09:34] <zeeshan|2> lookin good!
[18:09:52] <LeelooMinai> Tomorrow back to the control box - almost finished there too
[18:10:20] <LeelooMinai> But I have this CHinese temperature controller and I think I will put it in there and make it control the fan I have there
[18:10:40] <LeelooMinai> It also displays temperature, so it will be useful
[18:11:13] <LeelooMinai> One of those cheap ones: http://www.aliexpress.com/item/Hot-Sale-30A-220V-Digital-LCD-Temperature-Controller-Thermocouple-Thermostat-Regulator-with-Sensor-Thermocouple-Free-Shipping/1797236325.html?s=p
[18:12:14] <LeelooMinai> Will have to make a rectangular hole for it - I guess dremel time tomorrow too:)
[18:12:51] <tjtr33> nice work on the machine, whats the rear slot on the temp controller? clamp onto a bar?
[18:13:14] <LeelooMinai> It's protective cover
[18:13:48] <LeelooMinai> It has terminal connectors there and the cover is so nothing is exposed
[18:14:13] <Tom_itx> how thick are the sides on your mill?
[18:14:15] <Tom_itx> 1"?
[18:14:16] <LeelooMinai> And it has those nice orange lockers on the sides, so rectangular hole is all that is needed
[18:14:43] <LeelooMinai> Yes, 1"
[18:14:49] <zeeshan|2> yay
[18:14:52] <zeeshan|2> all my random wiring
[18:14:56] <zeeshan|2> finally set this circuit on fire
[18:15:05] <Tom_itx> what did you use to mill all the pieces for it?
[18:15:11] <zeeshan|2> i blew up the 33 ohm 7w resistor
[18:15:15] <LeelooMinai> Wood router:)
[18:15:34] <Tom_itx> cnc?
[18:15:46] <andypugh> zeeshan|2: You could try to sound more disappointed
[18:15:46] <LeelooMinai> No, $100 cheap wood rooter
[18:15:56] <zeeshan|2> andypugh: lol
[18:16:04] <zeeshan|2> dude im just gonna buy some proper hall sensors
[18:16:10] <zeeshan|2> and mount em on a custom aluminum plate
[18:16:15] <zeeshan|2> and not deal with this bullshit circuit anymore
[18:16:40] <zeeshan|2> ps i hate microelectronics
[18:16:41] <zeeshan|2> :-)
[18:16:43] <andypugh> Probably wise
[18:16:54] <LeelooMinai> I am also waiting for this thing to put in the control box: http://www.aliexpress.com/snapshot/6342921961.html
[18:16:56] <zeeshan|2> seriously i can buy a couple of digital hall sensors
[18:17:09] <LeelooMinai> So another hole I guess.
[18:17:09] <zeeshan|2> only thing i gotta watch out is for their orientation relative to each other
[18:18:05] <zeeshan|2> im really curious
[18:18:13] <zeeshan|2> how does one blow up a 33 ohm 7w resistor??
[18:18:41] <LeelooMinai> Like anything other - by passing too much current through it:)
[18:18:44] <tjtr33> zeeshan|2, isnt the position and orientation forced by the green pcb? https://www.flickr.com/photos/128539016@N05/15536981831/in/photostream/
[18:18:48] <andypugh> With 8w of power?
[18:18:59] <zeeshan|2> how did i manage to consume 8 w of power
[18:19:08] <zeeshan|2> tjtr33: yes
[18:19:16] <zeeshan|2> i have to replacat the pcb
[18:19:22] <andypugh> Right, sleep time
[18:19:28] <tjtr33> gnite
[18:19:30] <zeeshan|2> nite!
[18:20:02] <Tom_itx> zeeshan|2 you need one of these: http://tom-itx.ddns01.com:81/~webpage/temp/resistor2.jpg
[18:20:17] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/temp/resistor1.jpg
[18:22:03] <PCW> was the resistor in series with the voltage regulator?
[18:22:09] <tjtr33> Tom_itx, no he needs this kind or resistor http://www.thespecialistsltd.com/files/imagecache/product/files/real_cuffs.jpg

[18:29:17] <zeeshan|2> i need something like this
[18:29:26] <zeeshan|2> http://www.spectecsensors.com/Images/hall_effect_sensors.jpg
[18:29:27] <zeeshan|2> or that
[18:29:31] <zeeshan|2> LeelooMinai: work yuour magic
[18:29:37] <zeeshan|2> find me a chinese version
[18:29:38] <zeeshan|2> :D
[18:29:44] <LeelooMinai> Now, I saw this design many times. A carriage with four bearings, but woudln't the alu just wear off quckly?
[18:30:19] <LeelooMinai> And whole thing would get imprecise?
[18:31:21] <zeeshan|2> ^ yep
[18:32:03] <LeelooMinai> People seem to use it a lot since it's cheap and easy to do DIY
[18:32:37] <LeelooMinai> But I would not trust it just running over bare aluminum
[18:34:03] <tjtr33> there's very low force on reprap devices, so longer life than if contact is made like with wood router or ( dotn try this at home ) cutting metal using skate bearings on alum rails
[18:34:46] <LeelooMinai> Well, I just looked at this: http://i.imgur.com/cE6DDtx.png
[18:35:01] <LeelooMinai> In this case it seems like they have some non-alu insert there
[18:35:28] <LeelooMinai> Looks like steel to me
[18:35:58] <LeelooMinai> I think... could also be alu with different finish, but maybe not (?)
[18:35:59] <tjtr33> yeah the idea is being crowdsourced now but comes from BishopWisecarver, using hardened steel edges
[18:36:31] <CaptHindsight> there are a few vendors already
[18:36:36] <tjtr33> http://www.bwc.com/
[18:36:41] <LeelooMinai> I see that making those is easy once one have alu-ca[ab;e cnc
[18:36:50] <LeelooMinai> alu-capable*
[18:37:01] <LeelooMinai> You just need to source bearings
[18:37:34] <tjtr33> hard wheels & hard rails, attached to alum extrusions
[18:37:46] <LeelooMinai> Well, and have something that can tap the holes probably... I did not research this part yet:)
[18:37:47] <CaptHindsight> http://www.pbclinear.com/ as well with roller or polymer bearings
[18:37:56] <LeelooMinai> Some geared motors maybe?
[18:37:57] <zeeshan|2> http://www.ebay.com/itm/Hall-Effect-Hall-sensor-Proximity-Switch-NPN-3-wires-normally-open-magnet-/181560860056
[18:38:02] <zeeshan|2> is there more compact prox sensors
[18:38:04] <zeeshan|2> in this style
[18:38:23] <CaptHindsight> yes, but more $$
[18:38:30] <zeeshan|2> link
[18:38:31] <zeeshan|2> i need 9
[18:38:32] <LeelooMinai> CaptHindsight: Those seem like costing half my house:)
[18:39:40] <CaptHindsight> http://www.ebay.com/itm/like/311061234381?lpid=82
[18:40:04] <zeeshan|2> i want the round style
[18:40:09] <zeeshan|2> it'll be easier to align
[18:41:02] <CaptHindsight> http://www.newark.com/honeywell-s-c/ss49/ic-hall-effect-sensor-to-92-3/dp/95F5207?mckv=sRGg2Dffp|pcrid|53816209341|plid|&CMP=KNC-GPLA
[18:41:11] <CaptHindsight> pot and wire them
[18:41:20] <CaptHindsight> hard to get much smaller than that :)
[18:41:26] <zeeshan|2> CaptHindsight: i aint dealing with bloody electronics no more!
[18:41:29] <zeeshan|2> i need macroelectronics
[18:41:30] <zeeshan|2> :-)
[18:41:44] <tjtr33> festo & baumer both make 3mm to 12mm diameter proxes and halls, used a lot on european machines ( omron on japanese )
[18:42:27] <LeelooMinai> zeeshan|2: Electronics are fun. Look, I designed and assembled this one: https://www.flickr.com/photos/100017731@N03/12759704914/
[18:42:35] <zeeshan|2> really?
[18:42:38] <zeeshan|2> that is impressive
[18:42:48] <zeeshan|2> id suicide if someone asked me to do that
[18:43:06] <LeelooMinai> Yes, I design/make pcbs/devices from time to time - it's my new hobby.
[18:43:14] <LeelooMinai> fter being programmer in the past that is
[18:43:44] <zeeshan|2> if i get a npn prox sensor
[18:43:58] <zeeshan|2> what kind of input will the output of it need to connect to
[18:44:03] <zeeshan|2> pull down or pull up
[18:44:31] <tjtr33> LeelooMinai, your work is great, get someone who needs something done, and have them fund your machine as part of the project cost. ( use other peoples money OPM :)
[18:44:33] <LeelooMinai> zeeshan|2: Datasheet would tell you details needed to figure that out
[18:44:43] <zeeshan|2> LeelooMinai: the chinese sensors just say
[18:44:45] <zeeshan|2> pnp or npn
[18:44:54] <zeeshan|2> and 7i77 is pull down inputs
[18:44:57] <LeelooMinai> pnp npn are just bjt transistor types
[18:45:41] <LeelooMinai> I can only guess - npn normaly is turned on with high signal, and pnp with low signal on the gate
[18:45:53] <LeelooMinai> But without seeng details that's not 100%
[18:46:19] <LeelooMinai> Depends on the whole circut
[18:46:41] <LeelooMinai> on the base*
[18:46:48] <zeeshan|2> finding the link
[18:47:10] <zeeshan|2> http://www.ebay.com/itm/Hall-Effect-Hall-sensor-Proximity-Switch-NPN-3-wires-normally-open-magnet-NEW-/230979790688?pt=LH_DefaultDomain_0&hash=item35c777e760
[18:47:14] <LeelooMinai> Cannot you just use mechanical switches - you could figure those out:)
[18:47:27] <zeeshan|2> rofl
[18:47:33] <zeeshan|2> you know what
[18:47:36] <zeeshan|2> i might just do that
[18:47:39] <zeeshan|2> thats an excellent idea.
[18:47:49] <zeeshan|2> they wont consume much power easier
[18:47:49] <tjtr33> cam and microswitch cheap
[18:47:56] <zeeshan|2> ill use the magnet as the actaculator
[18:48:10] <zeeshan|2> or replace the magnet with a hemispehical shape
[18:48:17] <LeelooMinai> Or use small contactron and magnet
[18:48:32] <LeelooMinai> That will use zero power too
[18:48:40] <zeeshan|2> you saw what im controlling right?
[18:48:48] <LeelooMinai> No
[18:49:07] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/14926219104/
[18:49:18] <zeeshan|2> see the ring gears?
[18:49:19] <LeelooMinai> A tractor? :)
[18:49:23] <zeeshan|2> they have a magnet sticking out of them
[18:49:51] <zeeshan|2> originally they were using 3 hall sensors
[18:49:54] <zeeshan|2> to determine the position
[18:50:32] <LeelooMinai> Hmm, I don't think what I had in mind is called contactron in english
[18:50:43] <LeelooMinai> I kind of translated it directly from Polish
[18:50:47] <zeeshan|2> youre polish?
[18:50:49] <LeelooMinai> zeeshan|2: I mean reed switches
[18:50:55] <zeeshan|2> kurwa.
[18:50:56] <LeelooMinai> Yes
[18:51:00] <zeeshan|2> :D
[18:51:20] <LeelooMinai> zeeshan|2: http://www.dx.com/p/reed-switch-magnetically-controlled-switch-golden-5-pcs-306815?tc=CAD&gclid=CjwKEAiAv7ajBRCIldS7rp7wzFkSJAAA1n4DmLy0uQsFAwMgJTmyH6IDcABYzSj1quy3t5Tjj0OdVxoCriPw_wcB
[18:51:30] <LeelooMinai> Those will work with magnets without any power
[18:51:45] <LeelooMinai> You put magnet close to them and they close
[18:51:54] <zeeshan|2> i want something thats mechanically easy to assemble
[18:51:58] <zeeshan|2> thats why i was looking at the prox switches
[18:52:02] <zeeshan|2> cause they'd work with the magnet as is
[18:52:14] <zeeshan|2> but it seems like each prox switch consumes 200mA
[18:52:21] <LeelooMinai> Well, it's a tube with two leads - what simpler could it be:)
[18:52:33] <zeeshan|2> enclosed sensor would be nice.
[18:52:42] <LeelooMinai> Then enclose it
[18:52:46] <zeeshan|2> no
[18:52:46] <Tom_itx> http://www.dx.com/p/20454-lema-electrics-microswitch-short-lever-roller-black-yellow-10-pcs-173404
[18:52:50] <zeeshan|2> must buy as is
[18:53:27] <LeelooMinai> zeeshan|2: If I was doing it, I would prefer hall sensor over reed over mechanical
[18:53:27] <zeeshan|2> im really liking this microswitch idea
[18:53:36] <zeeshan|2> LeelooMinai: why
[18:53:57] <LeelooMinai> zeeshan|2: FOr reliability mostly
[18:54:05] <zeeshan|2> thats true
[18:54:08] <zeeshan|2> non contact wins
[18:54:25] <zeeshan|2> well help me figure it out!
[18:54:35] <LeelooMinai> zeeshan|2: You have those fancy machines - you can surely make small mounts for whatever sensor you get:)
[18:55:05] <LeelooMinai> zeeshan|2: Ok, then show me what you would prefer and we will figure it out.
[18:55:17] <zeeshan|2> http://www.ebay.com/itm/Hall-Effect-Hall-sensor-Proximity-Switch-NPN-3-wires-normally-open-magnet-NEW-/230979790688?pt=LH_DefaultDomain_0&hash=item35c777e760
[18:55:18] <zeeshan|2> this thing
[18:55:35] <zeeshan|2> i like it because i just need to go mill a small 1/8 plate of aluminum
[18:55:43] <zeeshan|2> accurately drill the holes
[18:55:52] <zeeshan|2> and plug em to a24v supply
[18:55:59] <LeelooMinai> Ok, give me a sec, I will quickly research it
[18:56:03] <zeeshan|2> the only confusming part is how the output signal interfaces w/ mr 7i77
[18:56:30] <tjtr33> make sure you allow some adjustment along the rotary travel ( like a curved slot that you bolt thru ).
[18:57:07] <zeeshan|2> tjtr33: i was thinking of doweling the plate
[18:57:17] <zeeshan|2> cause there is dowel location already
[18:57:20] <tjtr33> do you think that sensor's 'sensitive' area is a bit large? and causes quite a different trigger piint in differnt rotations?
[18:57:35] <tjtr33> a smaller diameter may offer less hysterisis
[18:57:37] <LeelooMinai> zeeshan|2: Ok, so it's vasically like a transistor with base driven by the hall effect
[18:57:44] <LeelooMinai> zeeshan|2: Like this: http://i.imgur.com/2Y6mjpC.png
[18:57:57] <tjtr33> yay wikipedia
[18:58:15] <LeelooMinai> SO when the magnet is close it will make transistor switch on
[18:58:23] <zeeshan|2> the ground needs to be shared between 7i77 and sensor right?
[18:58:29] <LeelooMinai> The picture I linked has NPN condiguration
[18:58:43] <LeelooMinai> zeeshan|2: Yes, well, or your field power
[18:58:59] <tjtr33> see those 2 vertiocal transitions? they work with the 'sensitive area' . bigger sensor = wider distance
[18:59:07] <LeelooMinai> I would think you would wire this into field inputs
[18:59:30] <LeelooMinai> zeeshan|2: So pretty simple - you can just treat it as a black-box switch
[18:59:32] <zeeshan|2> tjtr33: hmm you have good point
[18:59:42] <zeeshan|2> LeelooMinai: that is what i like to hear :)
[18:59:49] <tjtr33> skinny diamter = less problem.
[18:59:49] <zeeshan|2> best 2 words
[18:59:51] <zeeshan|2> or 1 word
[18:59:53] <zeeshan|2> blackBOX
[19:00:05] <LeelooMinai> zeeshan|2: You may need to limit current though - at least if it was inside like what I linked
[19:00:16] <LeelooMinai> Otherwise the NPN part would go boom
[19:00:18] <zeeshan|2> limit current on what
[19:00:23] <zeeshan|2> the supply?
[19:00:28] <LeelooMinai> But sensor may already have some current limit in there
[19:00:31] <tjtr33> oh, and some have indicator led on side, VERY handy for debugging ( on when active )
[19:00:41] <zeeshan|2> tjtr33: yes this one has that
[19:00:51] <zeeshan|2> ive seen these in industry just never wired one up
[19:00:56] <zeeshan|2> from scratch :/
[19:01:05] <tjtr33> Hal and parallel port time
[19:01:10] <zeeshan|2> my drill press tachometer uses it
[19:01:17] <zeeshan|2> but the instructions were included :-)
[19:01:56] <zeeshan|2> i think i should get NC hall sensors
[19:02:22] <PCW> the 7i77 needs PNP prox's
[19:02:23] <zeeshan|2> cause then just incase theres no power to one of the sensors for some reason
[19:02:54] <zeeshan|2> PCW: what happens if you accidently plug in a npn's output t the 7i77 input
[19:02:56] <zeeshan|2> do you blow it up
[19:03:01] <zeeshan|2> *to
[19:03:09] <PCW> it will do nothing
[19:03:14] <LeelooMinai> PCW: I would think that NPN would work with inputs too - depending how you wire them, no?
[19:03:15] <zeeshan|2> okay
[19:03:32] <PCW> nope PNP only
[19:03:44] <tjtr33> pnp vs npn proxes http://www.schneider-electric.co.uk/sites/uk/en/support/faqs/faq_main.page?page=content&country=UK&lang=en&id=FA142566&locale=en_US&redirect=true
[19:03:59] <PCW> well you can use NPN sensors but they need an external pullup
[19:04:13] <zeeshan|2> f that
[19:04:17] <LeelooMinai> Right
[19:04:20] <zeeshan|2> you know me and external resistors.
[19:04:20] <zeeshan|2> :)
[19:04:49] <LeelooMinai> zeeshan|2: So here you go - get PNP hall sensor and 5 yo will be able to connect it:)
[19:05:00] <zeeshan|2> thats what i like to hear!!
[19:05:09] <zeeshan|2> looks like the chinese dont make pnp
[19:05:30] <LeelooMinai> They make everything
[19:05:36] <zeeshan|2> i lied
[19:05:38] <zeeshan|2> i found :D
[19:05:47] <zeeshan|2> ugh
[19:05:50] <zeeshan|2> theyre capacitive.
[19:06:18] <LeelooMinai> COuld work too if you position them in the right place
[19:06:28] <LeelooMinai> Since the magnet seems to stick out from the plane
[19:06:46] <zeeshan|2> LeelooMinai: on alibaby
[19:06:49] <PCW> http://www.ebay.com/itm/10pcs-New-LJ12A3-4-Z-BY-Inductive-Proximity-Sensor-Switch-PNP-DC6-36V-/141441047899?pt=LH_DefaultDomain_0&hash=item20ee8b1d5b
[19:07:07] <zeeshan|2> PCW: too long
[19:07:12] <zeeshan|2> but that is a sweet deal
[19:07:42] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15536981611/
[19:07:48] <zeeshan|2> i dunno if you can see the 3 solder points there
[19:07:52] <zeeshan|2> thats where one of the sensor goes
[19:07:57] <zeeshan|2> then another goes 180 degrees from that and 90 degrees
[19:08:10] <zeeshan|2> if theyre too long it'll hit the metal mount of the motors
[19:08:12] <tjtr33> 3 per shaft right?
[19:08:15] <zeeshan|2> yes
[19:08:31] <PCW> you could also fix your sensor board that you fried
[19:08:40] <zeeshan|2> PCW: im not electronics savvy
[19:08:49] <zeeshan|2> even if i replace the resistor
[19:08:57] <zeeshan|2> (i already replaced a vregulator)
[19:09:03] <zeeshan|2> i dont have a proper wiring diagram..
[19:09:08] <tjtr33> what does the orig sensor look like? a T220?
[19:09:13] <zeeshan|2> so i've been chasing my tail
[19:09:19] <zeeshan|2> tjtr33: ugn3020t
[19:09:28] <zeeshan|2> i cant believe that's imprinted in my brain now
[19:10:16] <zeeshan|2> also i would like to use a hall prox senssor
[19:10:23] <tjtr33> but you talked about pin5? and ugn3020t is 3 pin trx style
[19:10:25] <zeeshan|2> so i can use the magnets that are on the ring gears as is
[19:10:38] <zeeshan|2> tjtr33: pin 5 on the input of the board
[19:10:42] <tjtr33> ok
[19:10:43] <zeeshan|2> not @ hall sensor
[19:12:24] <zeeshan|2> http://www.alibaba.com/product-detail/M12-hall-effect-magnetic-sensor-switch_1341685436.html
[19:12:25] <zeeshan|2> rofl
[19:12:31] <zeeshan|2> at the omron rip off logo
[19:16:41] <tjtr33> that style hall sensor define the position of the sensitive face, best to keep the board, wack off the control side, keep the mount position, get some sensors that fit the orig holes, maybe digikey US5881EUA-AAA-000-BU-ND
[19:17:16] <tjtr33> measure the hole spacing, i cant tel pkg size from photo
[19:17:56] <zeeshan|2> you bring up a good point
[19:18:06] <zeeshan|2> i should try injecting 24VDC into those sensors
[19:18:13] <zeeshan|2> and see if they switch
[19:18:19] <zeeshan|2> directly at the pins
[19:18:53] <PCW> They were run from 12V on the original circuit
[19:18:58] <tjtr33> use a round sensor and loose all reference, keep the pcb and you can take it on & off to work on. AND buy _one_ and try with parallel port ( cheap, and then you know it can work )
[19:19:37] <zeeshan|2> PCW: thats true
[19:19:42] <zeeshan|2> but spec sheet says they can handle 24v..
[19:19:46] <tjtr33> lotta 12 V sensors at digikey
[19:19:54] <tjtr33> 3-30
[19:20:17] <zeeshan|2> www.ebay.com/itm/5Pcs-M8-DC-PNP-NO-NC10mm-hall-effect-magnetic-sensor-NJK-5001AB-/141463210769?pt=LH_DefaultDomain_0&hash=item20efdd4b11
[19:20:18] <zeeshan|2> oonestly
[19:20:24] <zeeshan|2> i think it'll be easier for me personally
[19:20:26] <zeeshan|2> just do use these
[19:21:14] <PCW> is there room to mount those?
[19:21:21] <zeeshan|2> they look long
[19:21:24] <zeeshan|2> but theyre only 1" long
[19:21:30] <zeeshan|2> i have 2 1/4" gap
[19:21:52] <zeeshan|2> current magnet diameter is 7mm
[19:21:54] <zeeshan|2> so 8mm sensors should work
[19:21:59] <tjtr33> you dont want long range , look atthe gap you have now, isnt it like a mm or two at most?
[19:22:10] <zeeshan|2> tjb1: like 3 mm
[19:22:16] <zeeshan|2> maybe 4
[19:22:25] <tjtr33> long range allowed is ok, but dont _use_ long range
[19:22:32] <zeeshan|2> why
[19:22:57] <tjtr33> its an cone of sensitivity, as younear the vertex, its more accurate
[19:23:15] <zeeshan|2> when i shift the ring gears manually
[19:23:27] <zeeshan|2> there is at least 5-10 degrees of rotation
[19:23:34] <zeeshan|2> and the gear is still engaged
[19:23:51] <zeeshan|2> i'm not sure how it's working inside
[19:24:15] <zeeshan|2> maybe theres slotted gear selectors within the trans
[19:24:33] <tjtr33> staying at the same distance saves all the tolerance you have, moving away eats up more tolerance ( approaches 'it dont work anymore ')
[19:25:04] <zeeshan|2> ill place them as close as possible
[19:25:42] <tjtr33> just keep new sensor same distance from the 'dog' that trips it, and , use a sensor with same sensitive area ( face of same size )
[19:25:45] <zeeshan|2> i honestly dont even know why i am wasting time looking at this gear selector stuff
[19:25:51] <zeeshan|2> i only need back gear and no back gear
[19:25:56] <zeeshan|2> the rest can be vfd'ed
[19:26:07] <zeeshan|2> i gues it just intrigues me :P
[19:26:21] <tjtr33> M00 ( then shift by hand ) done
[19:26:26] <zeeshan|2> haha
[19:26:36] <zeeshan|2> only time ill need back gear is for tapping
[19:26:36] <zeeshan|2> thats it
[19:42:28] <zeeshan|2> spindle brake consumtpion .83A , hydraulic solenoid consumption 3A, .3A * 4 =1.2A contactor coil, 0.02*4=0.08A 24vdc relays , 1.8A (9 hall prox switches) = 6.91A
[19:42:35] <zeeshan|2> ddidnt even account for 7i77 yet
[19:42:45] <zeeshan|2> i only have a 6.5A 24vdc supply :/
[19:43:01] <zeeshan|2> most of these are intermittent loads though
[20:48:46] <PetefromTn_> evening folks
[20:50:02] <XXCoder> yo
[20:50:50] <PetefromTn_> well its supposed to get at least a LITTLE bit warmer this weekend
[20:51:17] <tjtr33> LeelooMinai, was your pcb an STM32 arm? just looked at Rene Hopf's project https://github.com/rene-dev/stmbl https://www.youtube.com/watch?v=sMeV4SCu4TA
[20:52:22] <LeelooMinai> tjtr33: I use STMs in my projects, yes
[20:55:47] <tjtr33> maybe diy of those surface mount devices really is possible
[20:57:39] <LeelooMinai> Sure it is - I use 0402 parts even:) and reflow oven made from toaster oven + controller I made.
[20:58:00] <LeelooMinai> And pcbs from China nowadays are cheap to fab
[20:58:12] <skunkworks> dad got his mazak lathe home.. Good deal... universial
[20:58:18] <LeelooMinai> It's kind of a golden age for elextronics as this
[20:59:06] <tjtr33> heh i thought that in the 7400 days
[20:59:32] <LeelooMinai> E, at that time things were not as cheap.

[21:00:11] <skunkworks> http://electronicsam.com/images/KandT/testing/DSC02122A.JPG
[21:00:11] <LeelooMinai> I have one like this in my kitchen too
[21:00:18] <LeelooMinai> Or maybe not:)
[21:00:18] <skunkworks> 20" Max Swing Over Bed, 12" max Cutting Diameter, 40.75" Max Turning Length, 2.5" max Bar Diameter
[21:00:29] <PetefromTn_> that looks like a sweet turning center man
[21:01:12] <tjtr33> nice skunkworks , you do have some room to play in dontcha
[21:02:44] <skunkworks> when we get rid of stuff... ;)
[21:08:00] <jdh> hey pete
[21:08:25] <PetefromTn_> hey
[21:08:30] <jdh> guess where I am
[21:08:41] <PetefromTn_> don't care
[21:08:51] <zeeshan|2> mean
[21:08:51] <zeeshan|2> lol
[21:08:55] <PetefromTn_> :D
[21:09:06] <zeeshan|2> pete already knows
[21:09:37] <PetefromTn_> man I was down at the race shop again today
[21:09:51] <PetefromTn_> those guys are working on some sick cars there..
[21:10:07] <PetefromTn_> I lost a lot of fluid drooling over them LOL
[21:10:16] <zeeshan|2> hehe
[21:10:20] <zeeshan|2> you machining something for them?
[21:10:26] <zeeshan|2> or just hanging out
[21:10:28] <PetefromTn_> trying to
[21:10:51] <PetefromTn_> we are working on a few designs but they are doing so many things they are finding it hard to concentrate LOL
[21:10:54] <jdh> http://tinyurl.com/modyk2
[21:11:14] <zeeshan|2> jdh wut
[21:11:20] <PetefromTn_> ?
[21:11:37] <PetefromTn_> I gotta tell ya man. I know you are not fond of that rotary mazda motor
[21:11:49] <PetefromTn_> but I think I am in love with the damn things
[21:12:09] <zeeshan|2> hehe
[21:12:11] <zeeshan|2> i like em
[21:12:13] <zeeshan|2> just not in my car!
[21:12:20] <zeeshan|2> too much work
[21:12:21] <jdh> http://tinyurl.com/modyk28 oops
[21:12:27] <PetefromTn_> they were dyno tuning one with almost 700HP
[21:12:31] <zeeshan|2> jdh
[21:12:36] <zeeshan|2> that looks like a run down motel sir
[21:12:38] <zeeshan|2> lol
[21:12:50] <PetefromTn_> and I have heard a lot of dyno runs but that thing sounds unfreakinbelievable
[21:12:51] <zeeshan|2> PetefromTn_: nice
[21:12:53] <jdh> fairly accurate description
[21:13:02] <zeeshan|2> hookers?
[21:13:10] <jdh> not likely
[21:13:21] <PetefromTn_> why does that sign look familiar?
[21:13:42] <jdh> looks like a 50s postcard
[21:13:53] <jdh> I take that picture a lot :)
[21:14:15] <PetefromTn_> it's like a really nasty angry godzilla bumblebee sound makes the hair stand up on the back of my neck LOL
[21:14:21] <zeeshan|2> haha
[21:14:25] <zeeshan|2> yea man theyre so nice sounding
[21:14:31] <zeeshan|2> smooth power delivery too
[21:15:05] <PetefromTn_> they were also working on a very mildly tuned Supra with like 465 HP that was pretty sweet.
[21:15:14] <PetefromTn_> 2JZ
[21:16:27] <zeeshan|2> what are you trying to build for them
[21:16:33] <PetefromTn_> https://www.youtube.com/watch?v=DOw_3wUmljg The RX7 looks a lot like this one only it is red.
[21:17:29] <PetefromTn_> well they want me to make a couple different things but they are trying to find the money to pay for a small run of the parts.
[21:17:53] <PetefromTn_> I just drop by to drool and say hello and they are really cool guys so it is kinda nice to chat with them.
[21:18:33] <PetefromTn_> I gotta say that I have never really been around these FD RX7's before
[21:18:55] <PetefromTn_> they really are a sweet little car and quite exotic looking once you add the nose and ground effects etc.
[21:19:58] <zeeshan|2> i love the body style
[21:20:03] <zeeshan|2> its a timeless style
[21:20:07] <zeeshan|2> can't believe its from the 90s :P
[21:20:19] <PetefromTn_> yeah I know right.
[21:21:06] <PetefromTn_> It really is a beutiful shape and with the JDM and aftermarket body kits it becomes something really special I think. I would love to have one to tinker on.
[21:21:35] <zeeshan|2> do it!!
[21:22:43] <zeeshan|2> hi PCW
[21:22:47] <zeeshan|2> would NPN - Open Collector, Inverted
[21:22:52] <zeeshan|2> work on the encoder side?
[21:23:02] <zeeshan|2> (optical encoder output)
[21:23:17] <PetefromTn_> how do they get a three or four rotor motor is it a custom crankshaft?
[21:23:39] <zeeshan|2> you can buy a 3 rotor
[21:23:43] <zeeshan|2> motor is from the cosmos
[21:23:51] <zeeshan|2> 4 rotor needs custom eccentric shaft
[21:24:04] <PetefromTn_> read...BIG MONEY!!
[21:24:11] <zeeshan|2> yea!!
[21:24:21] <zeeshan|2> i think it needs to be 2 piece.
[21:24:28] <zeeshan|2> because you cant assemble the engine otherwise
[21:24:34] <zeeshan|2> i could be wrong though
[21:26:35] <skunkworks> tjtr33: oh - no. that is where we picked it up...
[21:26:53] <PetefromTn_> https://www.youtube.com/watch?v=7NFgjO7v71U Drool...
[21:28:25] <PetefromTn_> I doubt I will be getting one anytime soon
[21:28:47] <PetefromTn_> but after being around them there I certainly would not mind having one LOL
[21:31:48] <LeelooMinai> So, hmm, how do you tap holes having a cnc mill? :)
[21:32:00] <zeeshan|2> what do you mean how
[21:32:05] <PetefromTn_> perfectly LOL
[21:32:25] <LeelooMinai> I mean what do you need in terms of hardware of course:)
[21:32:37] <zeeshan|2> quadrature encoder
[21:32:50] <zeeshan|2> + index pulse
[21:32:51] <jdh> reversible motor
[21:32:57] <jdh> or, a tapmatic head
[21:32:59] <zeeshan|2> VFD
[21:33:03] <zeeshan|2> :D
[21:33:13] <LeelooMinai> Ok, but you cannot do it with ac spindle I assume... I mean one would need something slow with high torque, no?
[21:33:26] <zeeshan|2> you can
[21:33:29] <zeeshan|2> thats why i said vfd
[21:33:37] <zeeshan|2> cause it outputs pretty much fuill torque at low speed
[21:33:50] <zeeshan|2> and im talking about rigid tapping
[21:34:15] <LeelooMinai> Weird... I thought those spindles work well only at high rpm
[21:34:45] <zeeshan|2> http://docs.engineeringtoolbox.com/documents/651/electric_motor_current_torque.png
[21:35:36] <LeelooMinai> Ok, but still - do those have enough of torque for tapping?
[21:36:00] <LeelooMinai> You just put a tap bit there and it works? :)
[21:36:34] * LeelooMinai googles tapmatic head
[21:36:36] <zeeshan|2> i've tapped using 2hp 3/4-UNC on the lathe
[21:36:50] <zeeshan|2> at 25 rpm
[21:36:54] <zeeshan|2> you can calculate the torque :P
[21:36:55] <LeelooMinai> Seems like some geared attachment
[21:37:10] <zeeshan|2> clutch packs
[21:37:32] <zeeshan|2> jdh: why arent you diving
[21:37:50] <LeelooMinai> So it prevents applying to much force basically?
[21:38:08] <zeeshan|2> yea and it has a mechanism i think a gear
[21:38:10] <zeeshan|2> to reverse direction
[21:38:37] <zeeshan|2> hey LeelooMinai deal hunter
[21:38:38] <zeeshan|2> http://circuits.datasheetdir.com/439/QVE00039-pinout.jpg
[21:38:41] <LeelooMinai> How much are those things?
[21:38:51] <zeeshan|2> can you find an optical photointerruptor with digital output for me
[21:38:52] <zeeshan|2> i need 3!
[21:38:54] <zeeshan|2> 5v
[21:38:57] <LeelooMinai> zeeshan|2: That looks like infrared breaker
[21:39:19] <zeeshan|2> ive seen the 50x go for 200 bux
[21:39:21] <zeeshan|2> used
[21:39:49] <LeelooMinai> Are they necessary for tapping or just a plus?
[21:39:51] <PetefromTn_> Leeloominai If you have a reversing spindle with reasonable torque you can use one of the Tormach or other offering floating tap heads.
[21:40:22] <PetefromTn_> they allow for some misalignment of the speed and feed to prevent breaking the tap
[21:40:43] <LeelooMinai> I see
[21:41:13] <LeelooMinai> SO it's floating along the spindle axis
[21:41:17] <PetefromTn_> I used to use one on my RF45 with 3hp 3phase spindle motor with belt drive
[21:41:31] <PetefromTn_> it actually worked quite well.
[21:43:04] <PetefromTn_> https://www.youtube.com/watch?v=jiGH-lGG_bw&list=UUFCopiUpaDrS5VBkrYFuGFQ
[21:43:05] <LeelooMinai> Nice CHinese people sell those for $140: http://www.aliexpress.com/item/ER32-FLOATING-TAPPING-CHUCK-M1-M27-MORSE-TAPER-MT3-SHANK-CNC-TAP-MILLING-L7506/1877412358.html
[21:43:22] <PetefromTn_> that is an old video I made with a cheap cellphone camera
[21:43:26] <zeeshan|2> ROFL
[21:43:35] <zeeshan|2> nice
[21:44:15] <LeelooMinai> PetefromTn_: I think I see a chuck there, and... well, that's all
[21:44:41] <PetefromTn_> watch the joint between the part that holds the tap and the body of the upper part
[21:44:48] <PetefromTn_> it is not just a chuck
[21:45:55] <zeeshan|2> finding a pnp type optical photointerrupter
[21:45:58] <zeeshan|2> is almost impossible!
[21:46:47] <LeelooMinai> PetefromTn_: Why is this tapping bit so weird - I mean it has this stretched spiral instead of dense one
[21:46:56] <PetefromTn_> that was only the second time I ever tapped with a CNC machine LOL the first time was on the same machine with some acrylic quarter inch plate
[21:47:21] <PetefromTn_> its just your typical spiral flute tap morse brand...I still have it here LOL
[21:47:29] <PetefromTn_> good tap
[21:47:42] <PetefromTn_> that one was 3/8-16
[21:47:55] <LeelooMinai> A, so that's flute for removing chips
[21:48:20] <LeelooMinai> The quality of the video is not very good:)
[21:48:31] <PetefromTn_> yeah they are great. I also use a lot of spiral point taps they are excellent too
[21:48:48] <PetefromTn_> yeah like I said it was done a long time ago with a cheapass cellphone camera
[21:49:32] <PetefromTn_> when you go get around to trying CNC tapping I highly recommend buying a good tap in either form to test with it makes all the difference
[21:49:53] <LeelooMinai> How do you make sure that the tap will be in the same place the drilling was? You just rely on CNC knowing the position between tool change?
[21:50:21] <PetefromTn_> yeah the hole should line up as long as you programmed the same location
[21:50:55] <PetefromTn_> the tap can only go in once tho it will not line up the second time with that setup due to the lack of precise spindle feedback
[21:51:32] <LeelooMinai> RIght, you would need to know the exact angle
[21:51:51] <PetefromTn_> yeah
[21:52:05] <zeeshan|2> LeelooMinai: the tap geometry effect chip evacuation
[21:52:08] <skunkworks> and encoder + index on the spindle and rigid tapping you can though...
[21:52:12] <zeeshan|2> spiral flute will route the chips towards the spindle
[21:52:19] <PetefromTn_> apparently once the spindle feedback is there in linuxCNC you might be able to use a peck tap op maybe I have not tried it tho.
[21:52:28] <zeeshan|2> will regular taps push em into the hole
[21:52:51] <PetefromTn_> I really like spiral flute taps
[21:52:54] <LeelooMinai> RIght, I have only normal tap set withouth any spiral flutes on them
[21:52:55] <zeeshan|2> yea man!
[21:52:56] <zeeshan|2> theyre awesome!
[21:53:24] <skunkworks> http://youtu.be/jAcFeVlftrw?list=UUHk52YjGT8HryRYmJKSl-lg
[21:53:26] <PetefromTn_> yeah they are probably just tapered hand taps not really ideal for CNC tapping but you could try it.
[21:53:51] <LeelooMinai> I am sure Chinese have all the kinds:)
[21:54:03] <PetefromTn_> damn that is sweet skunkie
[21:54:12] <zeeshan|2> skunkworks: you think pecking is necessary with spiral flute?
[21:54:20] <LeelooMinai> FOr example: http://www.aliexpress.com/item/7pcs-set-3-12mm-tap-die-set-hand-tools-titanium-coating-cutting-hole-HSS-taps-set/1983582452.html
[21:54:34] <skunkworks> it is when it is mounted in a drill chuck...
[21:54:42] <PetefromTn_> never used chinese taps
[21:55:04] <PetefromTn_> well I should say never used a GOOD chinese tap LOL
[21:55:08] <zeeshan|2> chinese taps....
[21:55:10] <zeeshan|2> those ones
[21:55:16] <zeeshan|2> TITANIUM COATED ALUMINUM TAPS!!
[21:55:22] <zeeshan|2> the base metal is always a mystery
[21:55:22] <zeeshan|2> haha
[21:55:24] <PetefromTn_> what is that part you made in that vid man?
[21:55:35] <PetefromTn_> I hate TI coated anything
[21:55:42] <PetefromTn_> never had much luck with it.
[21:55:45] <zeeshan|2> its great for stainless
[21:55:49] <zeeshan|2> but lame for aluminum
[21:55:52] <PetefromTn_> usually just get bright finish
[21:55:55] <PetefromTn_> for ally
[21:56:01] <skunkworks> PetefromTn_: some r&d stuff for a customer.
[21:56:11] <PetefromTn_> and Tialn or something like that for harder materials
[21:56:16] <PetefromTn_> oh okay
[21:56:40] <LeelooMinai> What is pecking?
[21:56:59] <PetefromTn_> watch skunkies tap video you will see it
[21:57:04] <LeelooMinai> DOing multiple passes?
[21:57:15] <PetefromTn_> yes basically
[21:57:17] <zeeshan|2> yea in the axial direction
[21:57:18] <zeeshan|2> :P
[21:57:54] <LeelooMinai> And what does it help with?
[21:58:02] <PetefromTn_> load
[21:58:06] <zeeshan|2> chip evacuation
[21:58:17] <zeeshan|2> otherwise youre recutting chips all the time
[21:58:24] <PetefromTn_> yup
[21:58:26] <zeeshan|2> and they also get jammed in between the cutter
[21:58:44] <PetefromTn_> skunkworks what is the code for the peck tap op?
[21:58:51] <zeeshan|2> PetefromTn_: was your spindle encoder
[21:58:58] <zeeshan|2> geared off the main spindle?
[21:59:02] <zeeshan|2> *is
[21:59:09] <PetefromTn_> no
[21:59:12] <PetefromTn_> its on the motor
[21:59:21] <FinboySlick> skunkworks: Your machine is such a beautiful monster.
[21:59:31] <zeeshan|2> did it come with your machine?
[21:59:41] <PetefromTn_> and the motor is setup with a 2-1 ratio to the spindle via timing belts
[21:59:44] <PetefromTn_> no
[21:59:47] <zeeshan|2> dude!!
[21:59:52] <zeeshan|2> ive been trying to findf one that works with 7i77
[21:59:54] <zeeshan|2> hook me up!
[21:59:56] <PetefromTn_> it is a nice HEDS
[22:00:09] <LeelooMinai> That tool changing thing is a bit scary
[22:00:10] <FinboySlick> skunkworks: Did you manage to get compensation for thermal expansion working?
[22:00:21] <PetefromTn_> basically any differential encoder will work with 7i77
[22:00:27] <zeeshan|2> http://www.digikey.com/product-detail/en/HEDS-5605%23A06/516-2024-ND/1990422
[22:00:36] <zeeshan|2> see the problem i notice is
[22:00:40] <zeeshan|2> they only have channel a and b
[22:00:42] <zeeshan|2> theres no index pulse
[22:01:03] <PetefromTn_> mine is made by the same people and it does have index
[22:01:06] <skunkworks> FinboySlick: yes - it works great for Z (spindle expanssion)
[22:01:11] <zeeshan|2> do you remember the part #?
[22:01:38] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15646666858/
[22:01:40] <PetefromTn_> trying to find it now
[22:01:44] <zeeshan|2> thats how my spindle look like
[22:01:53] <zeeshan|2> i have no clue how ill mount the heds style
[22:02:40] <PetefromTn_> mine is on the other end of the spindle motor in a custom machined mount underneath the original cover that protected the original resolver
[22:02:56] <tjtr33> cheap (YMMV) a b & Z encoders http://www.usdigital.com/products/encoders
[22:03:34] <zeeshan|2> tjtr33: not sure how i'd mount that style
[22:03:36] <zeeshan|2> any ideas?
[22:03:40] <zeeshan|2> lemme take a better pic of my spindle area.
[22:03:42] <zeeshan|2> i mean motor
[22:04:04] <tjtr33> they have shaft and thru hole types
[22:08:06] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15814597086/
[22:08:12] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15838243945/in/photostream/
[22:08:30] <tjtr33> use imagebin dangit
[22:08:40] <zeeshan|2> it looks a lot easier to a trigger wheel
[22:08:45] <zeeshan|2> cause thats what its currently doing
[22:08:57] <tjtr33> we cant zoom we can download why do need drm on these pix
[22:09:21] <LeelooMinai> I can zoom
[22:09:35] <tjtr33> windows user?
[22:09:46] <PetefromTn_> looks like your belt drive is a ribbed belt not a timing belt so you will need to put the encoder directly on the spindle somehow
[22:09:47] <LeelooMinai> Yes
[22:09:49] <tjtr33> no not firefox, that other thing
[22:10:14] <zeeshan|2> PetefromTn_: yes
[22:10:36] <tjtr33> chrome
[22:10:59] <PetefromTn_> you might be able to put a small timing belt pulley on the spindle top and then make a mount for the encoder with another shaft and bearing for the encoder
[22:11:40] <PetefromTn_> or you could do one of the home made jobs with a couple sensors and and index aperture plate mounted to the bottom of the original spindle
[22:11:45] <LeelooMinai> Chinese encoders are cheaper: http://www.aliexpress.com/item/Encoder-400P-R-Incremental-optical-rotary-encoder-400-pulse-r-AB-phase-encoder-6mm-Shaft-for/1342040248.html?s=p
[22:12:08] <zeeshan|2> LeelooMinai: and theyre chinese too
[22:12:10] <zeeshan|2> :)_
[22:12:30] <tjtr33> no Z phase, but some would be ABZ
[22:12:37] <LeelooMinai> THey are probably ok:)
[22:12:52] <zeeshan|2> like connors mpg
[22:12:55] <zeeshan|2> it was reallllllllllll good
[22:12:56] <zeeshan|2> :)
[22:13:02] * zeeshan|2 is trolling
[22:13:18] <zeeshan|2> PetefromTn_: the question is which is less work :)
[22:13:27] <PetefromTn_> http://www.avagotech.com/pages/en/motion_control_encoder_products/housed_encoders/incremental_housed_encoders/heds_hedm_hedl_5xxx_series/
[22:13:37] <PetefromTn_> I think that is the series model I have
[22:14:21] <LeelooMinai> I found attachment that can add small lathe-like capability to cnc: http://www.aliexpress.com/item/cnc-router-80mm-4th-aixs-with-4-Jaws-chuck-tailstock-rotational-rotary-axis-for-cnc-engraving/2052933631.html?s=p
[22:14:38] <zeeshan|2> wow
[22:14:39] <zeeshan|2> thats dirt cheap
[22:14:55] <tjtr33> but to drive it off the ribbed pulley... maybe machine the top face into a gear? and rt angle drive an encoder? lotta work
[22:14:57] <LeelooMinai> I guess with this one can do round objects
[22:15:03] <PetefromTn_> that picture must be the motor side of the drive no? Where is the power drawbar?
[22:15:24] <zeeshan|2> lemme try my best to explain
[22:15:26] <LeelooMinai> You attach this on x-y bed

[22:15:49] <zeeshan|2> motor transfers power to spindle like that
[22:15:55] <zeeshan|2> the spindle shaft that you see ther is horizontal
[22:16:12] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15540544082/
[22:16:24] <zeeshan|2> then the horizontal shaft fits into the vertical head
[22:16:27] <zeeshan|2> and drawbar is on there
[22:16:32] <zeeshan|2> the mill is both horizontal and vertical
[22:16:38] <PetefromTn_> ah nice
[22:16:41] <zeeshan|2> you just need to remov the head
[22:17:11] <zeeshan|2> i already have a trigger wheel made up from the lathe job
[22:17:13] <PetefromTn_> I would put the encoder on the main driven spindle pulley wherever that is not on the motor due to the fact it is not using a direct drive or timing belt
[22:17:26] <zeeshan|2> i totally agree
[22:17:32] <zeeshan|2> i like both the methods you suggested
[22:17:39] <zeeshan|2> i think the trigger wheel home made job might be easier
[22:17:54] <zeeshan|2> cause it means i just need to replace the current trigger wheel (have one already)
[22:17:57] <skunkworks> umm- don't you have a right angle gear box after that?
[22:17:59] <PetefromTn_> andypugh has some good pics of his DIY spindle feedback setup you can look at somewhere
[22:18:20] <zeeshan|2> i just cant find pnp optical sensors
[22:18:24] <zeeshan|2> skunkworks: what do you mean
[22:18:37] <tjtr33> maybe sacrifice a bit of that wide v belt, add a thin bicycle like gear to drive the encoder , or scrw the thing gear, make an encoder plate <1mm thick, use the reader head from usdigital or DIY
[22:18:45] <PetefromTn_> is there lash in the gear drive after the pulley..
[22:19:05] <zeeshan|2> yea there will be
[22:19:06] <zeeshan|2> :/
[22:19:18] <zeeshan|2> i dont know if its significant
[22:19:28] <skunkworks> you want the encoder mounted at the spindle.
[22:19:40] <PetefromTn_> ya know what would be nice is to change out the belt drive for a timing belt setup then it won't matter
[22:19:55] <zeeshan|2> yea but you still have the gear backlash prob
[22:20:10] <zeeshan|2> and i have no clue where i can mount it on the veritcal spindle
[22:20:19] <PetefromTn_> there is backlash in the gear head how bad is it?
[22:21:01] <tjtr33> oh that pic is not the final drive, doh!
[22:21:03] <zeeshan|2> i have no clue how i'd measure that in this setup
[22:21:35] <zeeshan|2> backlash on a gear train is pretty consistent though
[22:21:39] <zeeshan|2> *in
[22:21:45] <zeeshan|2> so maybe i can compensate for it
[22:24:13] <zeeshan|2> can you buy 1/8" wide timing belt? :D
[22:28:30] <tjtr33> does your spindle have this witches hat cover for the drawbar? http://ibin.co/1hxoGkRPtSa1
[22:40:57] <zeeshan|2> sorry for the delay
[22:41:10] <zeeshan|2> tjtr33: yes
[22:41:18] <zeeshan|2> witches hat
[22:41:19] <zeeshan|2> lol.
[22:41:23] <zeeshan|2> i measured the backlash
[22:41:32] <zeeshan|2> i used the drive teeth..
[22:41:39] <zeeshan|2> im measure 5.5 thou
[22:41:54] <zeeshan|2> it seems pretty consistent in different gears
[22:42:00] <zeeshan|2> changes by 1 thou at most
[22:42:19] <zeeshan|2> the only gears i will be using are medium and back gear
[22:42:29] <zeeshan|2> and it measurs 5.5 for both those :P
[22:42:59] <zeeshan|2> i took the pulley off and that trigger wheel is bolted onto the pulley
[22:43:09] <zeeshan|2> i think itll be a lot easier just to bolt another one on and use optical sensors
[22:43:32] <tjtr33> take the hat off and see if you can mount an encoder in there ( skunkworks is right, the encoder has to be on the spindle proper, anything more 'secondhand' will be iffy for rigid tapping )
[22:43:48] <zeeshan|2> tjtr33: but i can compensate for backlash
[22:43:52] <zeeshan|2> cause its consistent
[22:44:12] <zeeshan|2> but ill do that
[22:44:14] <zeeshan|2> brb :P
[22:44:19] <zeeshan|2> its -10 in the garage
[22:48:07] <XXCoder> zeeshan|2: -10? dang
[22:48:08] <XXCoder> thats warm
[23:00:30] <zeeshan|2> lol
[23:00:37] <zeeshan|2> tjtr33: took hat off
[23:00:42] <zeeshan|2> no easy way to mount it there :P

[23:01:37] <zeeshan|2> this looks nice
[23:35:35] <renesis> it says shenzen!
