[00:00:09] <zeeshan> so this board has 12 pins.
[00:00:13] <andypugh> So, each shaft makes about 4 full turns to select a gear and the outer ring gear and magnet tells the system when to stop
[00:00:18] <zeeshan> i know 9 wires from this board went to the control cabinet
[00:00:31] <zeeshan> 3 wires came from the optical photointerruptor on the spindle
[00:00:48] <zeeshan> so all this voltage regulator stuff
[00:00:58] <andypugh> Yeah, forget all that. This is screaming “GPIO and HAL component”
[00:00:59] <zeeshan> with that big ass resistor might be to step the voltage dowjn from 24v to 5v
[00:01:38] <zeeshan> so all i should care about
[00:01:47] <zeeshan> is the signals going to and coming from each one of those hall sensors
[00:01:52] <zeeshan> thats all i need on this board?
[00:02:08] <zeeshan> because based on those, i can pass the motor power through a relay
[00:02:16] <zeeshan> and that relay will be activated through 7i77 w/ linuxcnc
[00:02:29] <andypugh> I bet you 50p that if you wind the inner gears so that the magnets are at the various 3-o-clock and 9-o-clock positions you can select all 8 gears.
[00:02:58] <zeeshan> wind = rotate?
[00:03:00] -!- tocka has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]
[00:03:15] <zeeshan> winding to me is like "winding a torsional spring"
[00:03:16] <zeeshan> :)
[00:03:22] <andypugh> Make sure that the motors only need to turn one way, it may be that there are internal stops.
[00:03:34] <zeeshan> there are internal stops
[00:03:38] <zeeshan> i moved those splines manually
[00:03:42] <zeeshan> and engaged it in different gears
[00:03:45] -!- toudi has quit [Ping timeout: 244 seconds]
[00:03:55] <zeeshan> there seems to be 4 positions per gear
[00:03:57] <andypugh> Right, so you need bidirectional control of the motors.
[00:04:19] <andypugh> There may be 2 positions and 2 neutrals
[00:04:45] <andypugh> (for each shaft)
[00:05:00] <zeeshan> i have a diagram for another machine that is _similar_
[00:05:05] <andypugh> But as the sensors can’t see the neutrals, I doubt it.
[00:05:06] <zeeshan> but might be different

[00:05:52] <zeeshan> er ignore that one.
[00:06:01] <zeeshan> https://www.dropbox.com/sh/ti3t81sxkky36in/AAAGffuUME_d8rCreVbBW2Jxa/SCHEMATICS?dl=0#lh:null-maho_400e_schematics_12.png
[00:06:02] <zeeshan> this is it
[00:06:31] <zeeshan> https://www.dropbox.com/sh/ti3t81sxkky36in/AAAGffuUME_d8rCreVbBW2Jxa/SCHEMATICS?dl=0#lh:null-maho_400e_schematics_15.png
[00:06:33] <zeeshan> this is better
[00:06:44] <zeeshan> 4 positions "left right center left-middle"
[00:06:48] <zeeshan> whatever left middle is lol
[00:07:04] <andypugh> I would make a table for each of the 8 magent positions (left or right) turn the input shaft by hand, counting turns, for one chuck rotation. If the input shaft won’t turn in some positions then perhaps the neutral posiitons are important, but without a sensor for positive detection I dount it.
[00:07:40] <zeeshan> the thing is
[00:07:47] <zeeshan> its hard to tell if its engaged in a gear when moving by hand
[00:08:07] <zeeshan> its not like lathe gear selection on a lathe
[00:08:13] <zeeshan> where you can "hear" it click in
[00:08:30] <zeeshan> i guess i can rotate the spindle by hand
[00:08:37] <zeeshan> i mean the motor by hand
[00:08:45] <zeeshan> and see if the spindle spins, if it spins, i know its a discrete position
[00:08:55] <andypugh> That is what I was suggesting, and get a table ot gear ratios
[00:09:14] <zeeshan> once i have my table
[00:09:20] <zeeshan> how would the control work?
[00:09:31] <andypugh> I am moderately sure that the magnets should only be left or right, not anywhere inbetween
[00:09:48] -!- moorbo [moorbo!~moorbo@dyn-int-218-159.hrz.uni-kassel.de] has joined #linuxcnc
[00:09:57] <zeeshan> well to check that
[00:10:00] <zeeshan> i can power one of the hall sensors
[00:10:06] <zeeshan> and rotate the spindle by hand
[00:10:10] <zeeshan> spindle = gear
[00:10:31] <zeeshan> and see for each gear, what v_out is for each of the hall sensors per motor
[00:10:37] <zeeshan> (so 3x per motor)
[00:10:38] <andypugh> As for control, looks like CL or custom HAL component.
[00:10:53] <andypugh> You need to move motors, and that’s stateful
[00:11:20] <zeeshan> hall sensors output => input 7i77. output 7i77 -> relay -> motors
[00:11:21] <zeeshan> ?
[00:11:49] <zeeshan> im gonna play around with this circuit board
[00:11:51] <zeeshan> definitely interesting
[00:12:11] <zeeshan> i could transfer the concept over to the lathe
[00:12:18] <zeeshan> and have excellent torque
[00:12:36] -!- ve7it [ve7it!~LawrenceG@S01060014d19d0b68.pk.shawcable.net] has joined #linuxcnc
[00:12:40] <zeeshan> thanks!
[00:12:44] <andypugh> Ignoring for the moment where the gear request comes from, you would need to determine that Gear 3 was left-right-left (for example) and then move the motors until that was true before enabling the spindle.
[00:13:50] <tjtr33> im doing some state machine work in hal now, each state exits returning the next state to be executed.
[00:14:34] <andypugh> This is more fun in that you have three consecutive state machines.
[00:15:08] <andypugh> And that is how you would code it, run the three state machines in sequence, and enable spindle when all are back to state 0.
[00:16:01] <andypugh> zeeshan: Get your table and I will try to hack together a component, it sounds like fun.
[00:17:18] <andypugh> But now I need to sleep.
[00:17:22] <andypugh> Night all.

[01:11:10] <zeeshan> well its not as easy as i thought it'd be
[01:11:13] <zeeshan> powered the board with 24v
[01:11:20] <zeeshan> tried spinning the motors while monitoring some of the other pinouts
[01:11:28] <zeeshan> it doesn't seem to be a discrete output.
[01:16:18] <_methods> hahah if this was easy everyone would have a cnc lol
[01:17:08] <zeeshan> well
[01:17:11] <zeeshan> this feature isnt really necessary
[01:17:14] <zeeshan> i can shift the gears by hand
[01:17:16] <zeeshan> since i have vfd
[01:17:21] <zeeshan> i only need back gear and high gear
[01:17:22] <zeeshan> thats it
[01:17:28] <zeeshan> but it'd be nice to shift it atuomatically
[01:17:35] <zeeshan> to get optimum torque range

[02:37:55] <zeeshan> on cars they have load switches for the window motors
[02:38:02] <zeeshan> is there a proper name for these types of switches

[02:47:35] <zeeshan> okay :p
[02:47:51] <zeeshan> LeelooMinai: decode my electrical circuit
[02:47:52] <zeeshan> :/
[02:48:13] <LeelooMinai> You encoded it? :)
[02:48:19] <zeeshan> no :-(
[02:48:25] <zeeshan> manufacturer did
[02:48:28] <CaptHindsight> it depends on if it's just a current protection device that resets itself or is also a relay
[02:49:24] <LeelooMinai> I am still trying to figure out if it's legal for me to run that 240V to my room
[02:49:30] <zeeshan> it is
[02:49:42] <zeeshan> its no differnt than having a dryer in your room
[02:49:42] <zeeshan> :P
[02:49:47] <LeelooMinai> Without any inspection/approval?
[02:49:49] <zeeshan> infact baseboard heaters are 240v
[02:50:14] <zeeshan> doing it yourself
[02:50:25] <zeeshan> and not having it certified means you can get owned for insurance purposes
[02:50:37] <[cube]> i recently found out owning a 3d printer can render your home insurance useless - best to check ;)

[02:50:59] <[cube]> haha
[02:51:03] <[cube]> would if i could
[02:51:07] <LeelooMinai> [cube]: How so?
[02:51:24] <zeeshan> im suprised they covered ssi's house fire
[02:51:28] <CaptHindsight> what type of 3D printer?
[02:51:28] <zeeshan> and his laser did it
[02:51:31] <[cube]> insurance? its a fire hazard
[02:51:38] <[cube]> im not clear on that
[02:51:45] <[cube]> might only apply to hombrews
[02:52:01] <LeelooMinai> I wonder if having cnc in my room is bad too
[02:52:12] <[cube]> because i imagine makerbots etc have some kind of manufacturing certification for safe home use
[02:52:28] <CaptHindsight> are they UL listed?
[02:52:31] <[cube]> i think its mainly the temperatures involved and flammable plastic, cnc is probably fine
[02:52:32] <zeeshan> why do you guys think
[02:52:36] <zeeshan> i spend so much time going over my design shit
[02:52:44] <zeeshan> if a component failed and something went on fire
[02:52:49] <zeeshan> at least i can show them documentation
[02:52:52] <zeeshan> it'll hold up in court
[02:52:56] <[cube]> ah

[02:53:20] <zeeshan> *you
[02:53:27] <LeelooMinai> Hmm, I wonder how much is such inspection/certification
[02:53:32] <zeeshan> LeelooMinai: a lot
[02:53:33] <zeeshan> haha
[02:53:41] <[cube]> i just enclose dangerous components in metal enclosures, put a smoke detector and dont leave it unattended :P
[02:53:46] <zeeshan> it cost me 500 bux to get my 200amp garage panel inspected
[02:53:54] <[cube]> but that doesnt cover other fire causes
[02:53:55] <zeeshan> [cube]: exactly man
[02:53:59] <LeelooMinai> Damn...
[02:54:04] <[cube]> i wonder if something else cause a fire, and they still owned you for having a pritner

[03:04:23] <zeeshan> you use flickr too
[03:04:25] <CaptHindsight> yeah no copy or zoom :(
[03:04:47] <LeelooMinai> Right mouse button?
[03:04:48] <CaptHindsight> stop using flicker if you want help

[03:05:04] <renesis> srsly
[03:05:16] <renesis> just put the shit on imgur like a normal person
[03:05:18] <zeeshan> suggest a better site
[03:05:19] <zeeshan> imgur sux
[03:05:22] <renesis> ?
[03:05:22] <zeeshan> it makes your images smaller
[03:05:26] <renesis> ?
[03:05:36] <LeelooMinai> Or left - I see magnifying glass by default, click = zoom
[03:05:37] <CaptHindsight> imagebin.ca
[03:05:37] <renesis> you can get to them in full res?
[03:05:48] <zeeshan> you can with flickr too
[03:05:51] <zeeshan> if you download the image!
[03:05:52] <zeeshan> haha
[03:05:52] <renesis> how
[03:05:56] <renesis> oh wtf
[03:06:13] <renesis> retarded
[03:06:20] <zeeshan> im sure there is a way to zoom in
[03:06:23] <zeeshan> ppl have been doing it, i
[03:06:26] <zeeshan> i just dont know how
[03:06:30] <zeeshan> other than to download the image
[03:06:43] <zeeshan> https://www.flickr.com/photos/128539016@N05/15807464256/
[03:06:47] <zeeshan> heres a better zoom of it
[03:06:50] <[cube]> zeeshan, on imgur you just open the image in a new tab, it links to the JPG url full res
[03:06:59] <zeeshan> cube ok
[03:07:00] -!- patrick__ has quit [Remote host closed the connection]
[03:07:00] <zeeshan> oh
[03:07:03] <LeelooMinai> You guys don't have magnifying glass cursor on flickr?
[03:07:06] <[cube]> i typically middle click them
[03:07:12] <zeeshan> LeelooMinai: no?
[03:07:13] <zeeshan> ss?

[03:07:38] <zeeshan> another one
[03:07:47] <zeeshan> you can see the 3 hall switches
[03:07:54] <LeelooMinai> I have and just lef-clock to zoom
[03:07:55] <zeeshan> i figured out where the vcc and ground are for those
[03:08:00] <LeelooMinai> left-click
[03:08:04] <zeeshan> left click changes the pic..
[03:08:09] <zeeshan> to the next one for me
[03:08:34] <LeelooMinai> Weird - I have magnifying glass by default
[03:08:39] <zeeshan> what browser?
[03:08:46] <LeelooMinai> Chrome
[03:08:49] <CaptHindsight> http://www.oemsemi.com/ic/4528BDC/505467.html
[03:08:50] <zeeshan> im usefirefox
[03:09:04] <[cube]> top right full screens it
[03:09:07] <renesis> well reverse the board anyway
[03:09:10] <[cube]> no magnifying glass here

[03:10:09] <zeeshan> notice how it says 106
[03:10:13] <zeeshan> thats the V_out from the hall
[03:10:30] <zeeshan> pin #5 on the very top is 24vdc
[03:10:42] <zeeshan> pin 8 and 9 are ground
[03:12:08] <zeeshan> im gonna spend another hour trying to figure this out

[08:48:15] <archivist> you do use some crappy sites docdroid just has circling blobs fo rme
[08:49:16] <zeeshan> whats a better side

[08:50:06] <zeeshan> https://pdf.yt/d/3UuBLq6IAeRxgH9X
[08:50:07] <zeeshan> better?
[08:51:24] <archivist> both allow download but fail utterly at online view that they seem to be all about
[08:51:42] <zeeshan> lol
[08:52:04] <archivist> pdf is by far the worst format invented
[08:52:10] <zeeshan> i like it
[08:52:15] <zeeshan> ghostscript is the worst!
[08:53:01] <archivist> diagram reminds me of...badly draw boy
[08:53:10] <zeeshan> well
[08:53:19] <zeeshan> to be honest this is my first time reverse engineering a circuit
[08:53:21] <zeeshan> from a pcb
[08:53:24] <zeeshan> i tried my best
[08:53:38] <zeeshan> its quite hard to follow each trace
[08:53:40] <zeeshan> and figure out whats going on
[08:53:43] <zeeshan> its tedious
[08:53:49] <archivist> flow goes left to right not bottom to top
[08:54:00] <zeeshan> well the way the layout is
[08:54:04] <zeeshan> is how it's layed out on the pcb
[08:54:08] <zeeshan> i didnt want to lose track
[08:54:48] <zeeshan> do you know why there would be transistors at the pins?
[08:55:05] <archivist> open collector
[08:55:23] <zeeshan> that term is not familiar with me
[08:55:27] <zeeshan> in a car ecu
[08:55:36] <zeeshan> if you have that kind of setup, and you ground that transistor
[08:55:41] <zeeshan> you basically change the state
[08:55:50] <zeeshan> is that what an open collector is? :P
[08:56:03] <archivist> those things you call cap I bet are resister networks
[08:56:18] <zeeshan> really?
[08:56:28] <zeeshan> i measured resistance between each adjacent pin
[08:56:31] <zeeshan> there was no resistance
[08:56:36] <zeeshan> thats why i thought they were caps
[08:56:39] <zeeshan> cap networks
[08:56:41] <renesis> press the probes in harder
[08:57:14] <archivist> board is probably coated in a varnish
[08:57:22] <zeeshan> nahh
[08:57:29] <zeeshan> the solder joints are exposed
[08:57:47] <zeeshan> when i power 24vdc @ pin 5 and ground pin 8 or 9
[08:57:51] <renesis> sometimes the solder joints or the probes get a bit oxidized
[08:57:55] <zeeshan> the board powers up.
[08:58:16] <zeeshan> i measure 24vdc between pin 6 & ground
[08:58:22] <zeeshan> and also 24vdc between pin 7 and ground
[08:58:29] <zeeshan> all other pins are at 0.
[08:58:51] <archivist> passenger arrived /me gone
[08:58:58] <zeeshan> then i monitor pin 1 and ground and take a magnet and try to hover it around all the hall switches
[08:59:00] <zeeshan> nothing happens :P
[08:59:06] <zeeshan> archivist: cya!
[09:02:18] <zeeshan> ok sleep time

[16:26:22] <zeeshan|2> nice!
[16:28:26] <taiden> OK makes sense
[16:28:35] <taiden> i have a sata 500 gb hdd lying around. seems overkill but who cares i guess
[16:28:55] <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
[16:29:16] <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)?
[16:29:44] <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
[16:33:33] <taiden> what about something like this? http://www.amazon.com/MyDigitalSSD-Super-Boot-Drive-42mm/dp/B00KBZH746/ref=cm_cr_pr_product_top

[16:38:48] <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?
[16:38:52] <zeeshan|2> can someone confirm
[16:40:46] <pcw_home> Unless it is powering a large transformer it will not be switching inductive loads

[16:51:33] <zeeshan|2> it's not a question about where to buy it from
[16:51:35] <LeelooMinai> I doubt they are faulty in some way.
[16:51:52] <zeeshan|2> it was a question about the loads theyre switching
[16:52:22] <zeeshan|2> theres no ul rating on that?

[16:53:41] <LeelooMinai> You are to picky:) Switch is a switch:p
[16:53:50] <zeeshan|2> there are ratings for a reason
[16:54:00] <zeeshan|2> i've seen what happens (well not with a dinky little 100A switch)
[16:54:14] <zeeshan|2> but with 1000A switches when they're designed like shit
[16:54:19] <zeeshan|2> they blow up in your face
[16:54:23] <zeeshan|2> during a short circuit
[16:54:35] <LeelooMinai> It's probably cloned from something and tested

[16:54:54] <LeelooMinai> Chinese may be cheap, but they are not stupid
[16:55:05] <zeeshan|2> most chinese stuff is junk
[16:55:22] <zeeshan|2> taiwanese is great
[16:55:42] <LeelooMinai> Only the things designed to be so. They can make as good things as they want, but it must calculate for them.
[16:56:10] <zeeshan|2> i agree with that completely
[16:56:26] <zeeshan|2> apple products an example of that
[16:56:29] <LeelooMinai> It's a bit of an art - buying things from places like aliexpress
[16:56:44] <zeeshan|2> i refuse to buy shit with no certifications

[16:58:38] <zeeshan|2> vs install non approved stuff
[16:58:55] <LeelooMinai> Yes, but it's not always worth saving up just not to buy Chinese - it depends on context
[16:58:59] <zeeshan|2> it's like people installing cheapo chinese tires

[17:55:25] <roycroft> the most accurate way to meter propane is by weight

[17:59:43] <roycroft> then do something else and know it's not going to be accurate
[17:59:43] <archivist> hall effect meters rely on an accurate metering rotating device, and if the pressure is wrong they are incorrect
[17:59:53] <pcw_home> anything else is pretty much gawbage
[18:00:04] <roycroft> and especially with a liquified gas the pressure will vary considerably with temperature

[18:01:22] <roycroft> if i stick it in my lagering freezer, which is 1c, the meter goes down to empty
[18:01:29] <roycroft> yet it's still a full tank
[18:01:32] <roycroft> it varies that much
[18:01:54] <pcw_home> a good mass flow meter might work but is likely a lot more expensive than weighing the tank
[18:02:14] <roycroft> my gas bottles have a tare weight stamped on them
[18:02:21] <roycroft> so i just weigh them to determine how full they are
[18:03:55] <Jymmm> You can get a meter for $200.
[18:04:12] -!- md-2 has quit [Remote host closed the connection]
[18:04:35] <archivist> it will not be as accurate as weight
[18:05:18] <Jymmm> Maybe not, but the cost has to be worth it.
[18:06:07] <archivist> it is very expensive for a simple pulse counter
[18:07:24] <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 =)
[18:07:38] <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
[18:07:50] <roycroft> the second tank can be smaller
[18:08:37] <roycroft> that method is very accurate, but only at two points - when the tank is full and when it is empty
[18:09:10] <Jymmm> Heh, funny thing... I have 5x20lb tanks right now.
[18:09:17] -!- koo6 has quit [Ping timeout: 240 seconds]
[18:09:19] <roycroft> i have a bunch of 20lb tanks
[18:09:28] <roycroft> and my method is to use one until it's empty then swap
[18:09:38] <roycroft> and when i get a bunch of empties i refill them all
[18:11:58] <archivist> I go without heating
[18:12:18] <roycroft> i go without beermaking
[18:12:22] <roycroft> so just as important :P

[18:36:10] <CaptHindsight> I don't any specs on accuracy
[18:36:38] <CaptHindsight> so if they don't have any, then it's somewhere between Full and Empty

[18:37:24] <CaptHindsight> no specs, no claims
[18:38:27] <CaptHindsight> does their meter spin?
[18:38:46] <CaptHindsight> that might explain the hall sensor
[18:39:23] <_methods> don't most propane companies put telemetry on their tanks for refills anyways?
[18:39:36] -!- FreezingCold has quit [Ping timeout: 258 seconds]
[18:39:41] <Rab> Looks like some meters have remote takeoffs which use a hall effect sensor to measure the position of the needle.
[18:40:05] <CaptHindsight> it might assume that you enter in the assumed weight of the propane tank
[18:40:12] <roycroft> the propane companies around here don't want you knowing how full the tank is
[18:40:24] <roycroft> they charge by the gallon + a truck roll charge
[18:40:25] <Rab> How proportionality is derived from the hall effect, I don't know. But I don't think it's a flow meter.
[18:40:34] <CaptHindsight> heh, yeah sounds about right
[18:40:47] <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

[19:15:24] <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
[19:15:50] <andypugh> Sounds potentially useful, and you can probably re-use the existing Arduino driver.

[19:22:59] <Loetmichel> Topy44: because you know i use linuxcnc?
[19:23:08] <Topy44> Loetmichel: i actually didn't know, no
[19:23:12] <andypugh> Loetmichel: Have you tried Highland Park? I rather like that.
[19:23:28] <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?

[19:27:21] <andypugh> For a whiskey that really does have a distinctively different taste: http://www.malts.com/index.php/en_gb/Our-Whiskies/Talisker/Introduction
[19:27:49] <andypugh> I just recieved a bottle of Bourbon in payment for some motorcycle parts.
[19:30:37] <roycroft> i'm pretty sure i heard of a new distillery opening on the isle of skye
[19:30:50] <roycroft> i've never had talisker - i shall look for it
[19:31:11] <roycroft> it sounds expensive though
[19:31:48] <CaptHindsight> it's peaty
[19:32:02] <roycroft> i like laphroaig
[19:32:03] <roycroft> so
[19:32:11] <Rab> I know someone who was crazy about Talisker, and it was expensive.
[19:32:12] <CaptHindsight> not like Ardbeg but peaty for a non-islay
[19:32:20] <Rab> Tasted OK, but I'm not a whiskey drinker.
[19:32:32] <roycroft> talisker is whisky, not whiskey :)
[19:32:47] <roycroft> whiskey is from ireland
[19:33:31] <Rab> I'm from Texas, such subtleties are far beyond me.
[19:33:55] <andypugh> I saw my error and cringed but hoped I would get away with it.
[19:34:22] <roycroft> i'm not sure why
[19:34:24] <CaptHindsight> talisker 10 yo is ~$60 750ml
[19:34:41] <roycroft> but scots and canadians make whisky
[19:34:47] <roycroft> irish and usians make whiskey
[19:35:25] <roycroft> and i'm not sure how that stuff from the new distillery in london is spelled
[19:35:39] <roycroft> england hasn't produce whisk[e]y in a long long time until just now
[19:35:46] <andypugh> Talisker is £30 a bottle here
[19:36:12] <roycroft> i guess we'll find out in a decade or so how it's spelled
[19:36:31] <andypugh> Laphroig is £29, Highland Park also £33.
[19:37:18] <CaptHindsight> how much for Ardbeg?
[19:38:21] <andypugh> £47
[19:38:35] <CaptHindsight> huh, lower here
[19:39:27] <CaptHindsight> at least it the real stuff
[19:40:35] <andypugh> of course, you can pay more: http://www.masterofmalt.com/whiskies/ardbeg/ardbeg-1974-provenance-with-presentation-box-whisky
[19:41:42] <CaptHindsight> all those special packages and special casks
[19:42:05] <CaptHindsight> many are not anything special but become collectors items
[19:42:41] <Loetmichel> roycroft: talisker is nice
[19:43:08] <Loetmichel> things i would want to avoid is anything with "dimple" in name ;-)
[19:43:22] <CaptHindsight> Loetmichel: did your bottle ever arrive?
[19:43:30] <Loetmichel> it will tomorrow
[19:43:39] <Loetmichel> says the dhl tracking
[19:43:42] <CaptHindsight> "dimple"?

[19:45:20] <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?

[19:45:31] <andypugh> Yes

[19:46:32] <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)
[19:46:48] <Topy44> ok great
[19:47:36] <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
[19:51:46] <Rab> Topy44, what type of virtualization? VMware, VirtualBox, etc?
[19:51:54] <Topy44> virtualbox
[19:52:19] <CaptHindsight> Topy44: how are you connecting the *duino to the PC?
[19:52:33] <Rab> Topy44, I'm interested to know how that turns out. Passthrough for the hardware might be a challenge.
[19:53:01] <Topy44> CaptHindsight: just the usual way, hook up the device and tell virtualbox to connect it?
[19:53:14] <CaptHindsight> PC---> USB ---> *duino
[19:53:20] <Topy44> its a leonardo-clone, so no ftdi chip
[19:53:51] <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)
[19:54:08] <Topy44> (i don't really use arduino stuff much, but this should do just fine as a test platform)

[21:22:53] <renesis> rab: oh, cradek already answered so is officially answered

[22:46:03] <zeeshan|2> still makes no sense to me
[22:46:20] <andypugh> Doesn’t it just output 6 signals?

[22:47:08] <andypugh> Ah, in that case I suggest removing components until it is that simple and then doing the clever stuff in HAL.
[22:47:32] <zeeshan|2> the transistors might be upside down
[22:47:36] <zeeshan|2> in that diagram
[22:47:49] <renesis> well
[22:47:53] <zeeshan|2> my problem is i have no clue where the vcc goes to

[22:47:55] -!- PCW [PCW!~chatzilla@] has joined #linuxcnc
[22:48:22] <zeeshan|2> i can see that pin 1-4 11-12 are something to do with the hall sensors.

[22:48:35] -!- tmcw has quit []
[22:48:47] <zeeshan|2> ren when i put ohmmeter betweren vreg input to pin 5
[22:48:49] <zeeshan|2> i got continuity
[22:49:10] <zeeshan|2> when i measure resistance i get 0-1 ohm
[22:49:26] <zeeshan|2> when i measure resistance for vreg out to pin 5, i get like 50k ohm
[22:49:32] -!- sumpfralle has quit [Ping timeout: 258 seconds]
[22:49:33] <zeeshan|2> which makes 0 sense.
[22:49:38] <renesis> i wouldnt use continuity testing to trace this
[22:50:34] <andypugh> Maybe the circuit makes sense to PCW? (who does seem to understand electronics)
[22:50:37] <renesis> im not sure, but continuity test might beep through a diode
[22:51:43] <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
[22:52:15] <zeeshan|2> ok ill retrace manually
[22:53:08] <renesis> yeah my fluke is showing a 1n914 as like 340R
[22:53:19] <renesis> i dont think itll beep until <10R
[22:53:48] <renesis> anyway, check ohms when you see a beep
[22:54:00] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15210012634/
[22:54:00] <renesis> 9R is not the same as 0R in a lot of contexts
[22:54:06] <zeeshan|2> is bottom most pin input or output for the vreg
[22:54:07] <renesis> like working on speakers =\
[22:54:15] <zeeshan|2> http://fixit-service.kz/files/L7812CV.pdf
[22:54:21] <zeeshan|2> from what im grasping from page 2
[22:54:29] <zeeshan|2> looks like ouput
[22:54:44] <andypugh> Alternatively, ignore _how_ the PCB works and see what the output pins do when you hold a magnet near each switch.
[22:54:51] <zeeshan|2> andypugh: i did
[22:54:53] <zeeshan|2> nothing happens
[22:55:02] <zeeshan|2> it might be in "crap mode"
[22:55:14] <zeeshan|2> because this board experts to be hooked up to a hall microswitch

[22:55:24] -!- lyzidiamond has quit [Client Quit]
[22:55:29] <zeeshan|2> so when the spindle isnt spinning, the outputs work
[22:55:40] <zeeshan|2> but im not sure where the sensor wires up to
[22:55:41] <andypugh> Maybe
[22:57:49] <zeeshan|2> fuck
[22:57:53] <zeeshan|2> sorry for the language
[22:57:57] <zeeshan|2> but i think pin 10 is VCC.
[22:58:03] <renesis> pin 3 is output, pin 2 is ground
[22:58:33] <zeeshan|2> which means i musta drawing the schematic wrong.
[22:58:53] <renesis> you put 24V on the output
[22:59:07] <renesis> and you saw a diode drop at the other end of the vreg
[22:59:32] <zeeshan|2> yuea no wonder why my vreg wouldnt show 12v
[22:59:37] <zeeshan|2> i had 24v going to the bloody output
[22:59:58] <zeeshan|2> if you look at the schematic
[23:00:02] <zeeshan|2> why is there a resistor
[23:00:05] <zeeshan|2> er nm
[23:01:23] <zeeshan|2> its a bit weird
[23:01:41] <zeeshan|2> that pin 10 has a resistor at the input side of the v-reg.
[23:01:53] <renesis> what size resistor
[23:01:56] -!- afiber__ has quit [Quit: Konversation terminated!]
[23:02:00] <zeeshan|2> says 33R on it
[23:02:03] <zeeshan|2> its a 7W resistor
[23:02:22] <renesis> and with a known max load current, you can use a resistor to pull power away from the vreg without dropping it out
[23:02:31] <renesis> yeah, thats what that resistor is doing
[23:02:48] <renesis> the resistor is probably cheaper than a heatsink for the 7812
[23:02:50] <zeeshan|2> i hope i didnt fry crap
[23:02:54] <zeeshan|2> but hooking up 24v to pin 4
[23:02:55] <renesis> get away with the pcb sink on the other side
[23:02:56] <zeeshan|2> pin 5
[23:02:57] <zeeshan|2> lol
[23:03:17] <renesis> do you have data for the hall sensors?
[23:03:28] <renesis> theyll have abs max voltage in the first couple pages
[23:03:36] <zeeshan|2> 24v is abs max voltage
[23:03:43] <zeeshan|2> for most of the components except 4528bdc
[23:03:49] <renesis> what kind of supply are you using
[23:03:49] <zeeshan|2> that specifies 18v
[23:03:52] <zeeshan|2> smps
[23:03:56] <renesis> yeah you prob blew that
[23:04:02] <zeeshan|2> the psu?
[23:04:06] <zeeshan|2> psu is fine
[23:04:07] <renesis> no the opamp

[23:17:48] <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.
[23:18:00] <zeeshan|2> i tried the 24v dc shock test
[23:18:04] <zeeshan|2> its just like 12v
[23:18:06] <zeeshan|2> doesnt hurt :P
[23:18:30] <zeeshan|2> my resistance is too much :]
[23:18:40] <zeeshan|2> so it looks like even with the correct vcc and ground
[23:18:45] <zeeshan|2> the sensors dont switch.
[23:19:13] <andypugh> Maybe your magnet is too strong, too weak, or the wrong monopole?
[23:19:26] <zeeshan|2> andypugh: btw i looked at the motors closest
[23:19:29] <zeeshan|2> *closely
[23:19:36] <zeeshan|2> there are no magnets in there?
[23:19:40] <zeeshan|2> i cant stick any metal to em.
[23:20:00] <andypugh> Probably induction motors of some sort.
[23:20:08] <andypugh> Maybe even shaded-pole
[23:20:30] <zeeshan|2> so its picking up the mag field of the motors?
[23:20:34] <andypugh> Until recently _most_ motors had no permanent magents in them
[23:20:45] <zeeshan|2> so i mean for hall sensing
[23:20:55] <andypugh> No, it is picking up the magnets on the internally-toothed gears
[23:21:06] <zeeshan|2> i cant stick metal to it?
[23:21:14] <zeeshan|2> oh.
[23:21:19] <zeeshan|2> hm......
[23:21:24] <CaptHindsight> counts gear teeth as they go by by changing state
[23:21:31] <andypugh> (I asume those lumps are magnets)
[23:21:44] <zeeshan|2> ha
[23:21:49] <zeeshan|2> those things are prolly magnets
[23:21:52] <zeeshan|2> i was thinking it was inside the gear.
[23:21:54] <zeeshan|2> lemme go check
[23:22:03] <zeeshan|2> gear = spline
[23:22:34] <CaptHindsight> yeah splines vs teeth
[23:22:39] <CaptHindsight> but you get the point
[23:22:47] <CaptHindsight> high and low points
[23:23:09] <CaptHindsight> Hall sense On or OFF
[23:23:15] <zeeshan|2> im clearly blind
[23:23:15] <CaptHindsight> high low
[23:23:17] <zeeshan|2> andypugh: you are right
[23:23:19] <zeeshan|2> those are magnets.
[23:24:29] <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
[23:30:57] <zeeshan|2> yes
[23:31:24] <zeeshan|2> the cylindrical magnet's ends are parallel with the hall sensors

[23:37:00] <andypugh> I don’t know, I wouldn’t bet on it with the rest of the board unconected.

[23:37:17] <zeeshan|2> i really feel like its something to do wit hthe spindle speed sensor
[23:37:21] <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 )
[23:37:22] <zeeshan|2> if its disconnected, its in limp mode
[23:37:45] <andypugh> Was it all working before?
[23:37:58] <zeeshan|2> yes apparently this was a working machine
[23:38:05] <zeeshan|2> so far i havent found any evident thats its bad
[23:38:10] <zeeshan|2> (the machine)
[23:38:23] <zeeshan|2> one important thing to note is
[23:38:33] <zeeshan|2> pin 5 goes to collector all the transistors
[23:38:44] <andypugh> Have you looked at the datasheet for the sensors? Is there a typical circuit?
[23:38:59] <zeeshan|2> http://www.datasheet-pdf.com/datasheetdownload.php?id=630733
[23:39:02] <zeeshan|2> this is all i see
[23:39:21] <andypugh> (I have to look up what the collector even is, so my helpfulness is likely to be limited.)
[23:39:36] <zeeshan|2> im on the same boat
[23:41:10] <zeeshan|2> im gonna try hooking up the external speed sensor and see what happens
[23:41:21] <zeeshan|2> fire extinguisher is ready
[23:41:55] * Jymmm hands zeeshan|2 the explosives and runs like hell!
[23:42:06] <zeeshan|2> lol
[23:43:08] <Jymmm> Actually, that gave me a great idea!
[23:44:46] <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.

[23:46:38] * LeelooMinai finished installing limit switches today, finally
[23:47:04] <tjtr33> Sprague! woof that is old, from the uln sprague driver days (80's)
[23:47:32] <LeelooMinai> I did not really trust my old, setup.
[23:47:44] <LeelooMinai> I have them like this now: https://www.flickr.com/photos/100017731@N03/15650776467/

[23:49:42] <zeeshan|2> lookin good!
[23:49:59] <LeelooMinai> Tomorrow back to the control box - almost finished there too
[23:50:27] <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
[23:50:47] <LeelooMinai> It also displays temperature, so it will be useful
[23:51:20] <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
[23:52:21] <LeelooMinai> Will have to make a rectangular hole for it - I guess dremel time tomorrow too:)
[23:52:58] <tjtr33> nice work on the machine, whats the rear slot on the temp controller? clamp onto a bar?
[23:53:22] <LeelooMinai> It's protective cover
[23:53:55] <LeelooMinai> It has terminal connectors there and the cover is so nothing is exposed
[23:54:20] <Tom_itx> how thick are the sides on your mill?
[23:54:22] <Tom_itx> 1"?
[23:54:23] <LeelooMinai> And it has those nice orange lockers on the sides, so rectangular hole is all that is needed
[23:54:50] <LeelooMinai> Yes, 1"
[23:54:57] <zeeshan|2> yay
[23:54:59] <zeeshan|2> all my random wiring
[23:55:03] <zeeshan|2> finally set this circuit on fire
[23:55:12] <Tom_itx> what did you use to mill all the pieces for it?
[23:55:18] <zeeshan|2> i blew up the 33 ohm 7w resistor
[23:55:23] <LeelooMinai> Wood router:)
[23:55:42] <Tom_itx> cnc?
[23:55:53] <andypugh> zeeshan|2: You could try to sound more disappointed
[23:55:53] <LeelooMinai> No, $100 cheap wood rooter
[23:56:03] <zeeshan|2> andypugh: lol
[23:56:11] <zeeshan|2> dude im just gonna buy some proper hall sensors
[23:56:17] <zeeshan|2> and mount em on a custom aluminum plate
[23:56:22] <zeeshan|2> and not deal with this bullshit circuit anymore
[23:56:47] <zeeshan|2> ps i hate microelectronics
[23:56:49] <zeeshan|2> :-)
[23:56:50] <andypugh> Probably wise
[23:57:01] <LeelooMinai> I am also waiting for this thing to put in the control box: http://www.aliexpress.com/snapshot/6342921961.html
[23:57:03] <zeeshan|2> seriously i can buy a couple of digital hall sensors
[23:57:13] postaL_offline is now known as postaL
[23:57:16] <LeelooMinai> So another hole I guess.
[23:57:16] <zeeshan|2> only thing i gotta watch out is for their orientation relative to each other

[23:58:13] <zeeshan|2> im really curious
[23:58:20] <zeeshan|2> how does one blow up a 33 ohm 7w resistor??
[23:58:49] <LeelooMinai> Like anything other - by passing too much current through it:)
[23:58:51] <tjtr33> zeeshan|2, isnt the position and orientation forced by the green pcb? https://www.flickr.com/photos/128539016@N05/15536981831/in/photostream/
[23:58:55] <andypugh> With 8w of power?
[23:59:07] <zeeshan|2> how did i manage to consume 8 w of power
[23:59:15] <zeeshan|2> tjtr33: yes
[23:59:23] <zeeshan|2> i have to replacat the pcb
[23:59:29] <andypugh> Right, sleep time
