[02:35:02] <Deejay> moin
[02:35:35] <XXCoder> yo
[02:53:00] <XXCoder> https://www.youtube.com/watch?v=OtZQoIheYcc
[02:53:04] <XXCoder> laser cut steel
[02:53:21] <XXCoder> make a circuit board can put on anything apparently (nonconductive surface)(
[02:56:17] <Deejay> hihi
[02:56:42] <Deejay> but no vias
[03:26:25] <XXCoder> https://www.amazon.com/URBEST®Inlet-Module-Switch-Socket-IEC320/dp/B00ME5YAPK
[03:26:36] <XXCoder> wonder if it can handle enough current for my entire cnc
[03:26:59] <XXCoder> 10A maybe not
[05:23:02] <__rob> http://www.avagotech.com/products/motion-control-encoders/absolute-encoders/single-turn-encoders/as38-h39e-k
[05:23:07] <__rob> anyone know how this is so cheap
[05:23:21] <__rob> compared to anything else I can find of that size and resolution
[05:23:31] <__rob> its like $90 or so
[05:23:55] <__rob> wondering what the tradeoff is with that vs $500 one
[05:25:25] <__rob> 23bits of absolute resolution
[05:26:35] <XXCoder> interesting. no iea
[05:26:38] <XXCoder> idea
[05:27:13] <__rob> no, seems cheap tho, no ?
[05:27:26] <__rob> or am I missing some other compareable one that cheap
[05:30:25] <archivist> the technology is interpolated so resolution <> accuracy and there is a latency
[05:33:21] <archivist> see "position calculation time" for example
[05:34:29] <jthornton> morning
[05:38:19] <XXCoder> archivist: I guess cheap ones fine for slow rotations
[05:38:31] <XXCoder> or do it add too much latency anyway?
[05:38:45] <archivist> I guess they need to go fast enough to generate as well
[05:39:49] <archivist> they dont quote a maximum angular error either
[05:40:57] <XXCoder> in my experence so far, its things they dont say that gonna watch out
[05:43:30] <archivist> an expensive encoder will have a maximum angular error quoted
[06:00:04] <Meduza> Anyone in here that have used ClearPath servos or something similar with LinuxCNC?
[06:01:09] <Meduza> Looking to upgrade my small mill to get some more speed out of it (right now it uses old round pretty short stacked Nema34 motors from early 80's, wich have terrible acceleration/speed performance even with pretty ok drivers)
[06:04:19] <Meduza> or should i just go for newer steppers, or even some of the chinese stepper servo solutions?
[06:19:17] <archivist> plain servo
[06:22:28] <archivist> it is a question of who is in control, linuxcnc or some external device with no proper feedback
[06:22:29] <Meduza> archivist: i am getting quite put of by those since it always is getting so crazy expensive
[06:23:34] <Meduza> i cannot put down 1500$+ in a small desktop mill (that i am not even using that much, but have lent to our local makerspace) to get some faster speeds...
[06:25:15] <archivist> if they can use pwm and have encoder feedback to linuxcnc
[06:26:50] <Meduza> archivist: any leads on what cheap(ish) servo system to get? sub-1000$ range for 3 axes
[06:27:30] <XXCoder> there is fairly large gap between steppers and servos. bit annoying
[06:27:54] <archivist> they make the clearpath difficult to choose what you want
[06:29:24] <Meduza> I also run the mill on a parport setup right now, i probably have to get some mesa card to run servos, right?
[06:30:13] <archivist> you can use the clearpath stepdir but are limited to the par port step rate
[06:33:44] <Meduza> archivist: in some way that would probably be OK, since i am running with pretty ok step rates, it is just the motors that cannot keep up, on the other hand it feels wrong to use a system that is closed in the motors rather than the control software
[06:53:24] <__rob> archivist they do say the accuracy as +-60 arcsec
[06:54:16] <__rob> <archivist> I guess they need to go fast enough to generate as well
[06:54:18] <__rob> what do you mean here ?
[06:55:23] <archivist> er +- 80 arc secs
[06:55:44] <archivist> typical rather than maximum
[06:55:58] <XXCoder> archivist: how many um in millisecond?
[06:56:01] <XXCoder> forgot
[06:56:22] <XXCoder> linuxcnc good latency is around 20k um to 50 um correct too?
[06:56:36] <archivist> how long is a piece of string, how fast are you moving
[06:58:11] <XXCoder> err ms to us
[06:58:20] <XXCoder> apparently 1,000 us to ms
[07:01:23] <__rob> archivist, yea 3.5us calculation time
[07:01:29] <__rob> which isn't too bad really
[07:01:47] <__rob> SSI runs upto @ 1mhz
[07:02:05] <__rob> so 25k reads a second
[07:02:41] <__rob> seems pretty neat for the money
[07:03:07] <__rob> been using their 2 part encoder for a while, cant seem to keep it aligned tho
[07:03:12] <__rob> 17 bit one
[07:08:45] <archivist> I would like to measure one for a giggle one day in comparison to a normal one
[07:10:13] <XXCoder> other channel is chatting about usb controllers
[07:10:27] <XXCoder> apparently usb cache data for 16 ms before sending em in packet
[07:10:33] <XXCoder> but can be set to 1 ms
[07:10:41] <XXCoder> but latency is still huge
[07:11:29] <archivist> under runs can be as bad as overrun on usb
[07:11:47] <XXCoder> whats effect of underrun
[07:12:15] <archivist> data not ready machine in flight
[07:15:20] <archivist> here you have two or more stacked latencies, the motion planner usb and the control in the usb device
[07:16:23] <archivist> mentions of screwed up threading in a certain other system :)
[07:16:43] <XXCoder> mach3?
[07:22:08] <archivist> and 4
[07:22:15] <XXCoder> ah
[07:25:01] <archivist> I have no hesitation with internal threads to a shoulder without a safety groove with linyxcnc
[07:26:11] <XXCoder> shoulder without a safety groove?
[07:28:45] <archivist> thread on this nut http://www.collection.archivist.info/searchv13.php?searchstr=nipple
[07:29:51] <archivist> made about 5 years ago, still not fitted, had it in my hand yesterday :)
[07:30:17] <witnit> risky click
[07:30:26] <XXCoder> ahh I understand what you mean now
[07:30:34] <XXCoder> so threads inside go all way to end
[07:30:38] <XXCoder> blind end tap?
[07:31:03] <archivist> single point threading tool, taper pull out
[07:31:19] <XXCoder> witnit: btw theres a nipple take a look
[07:31:51] <witnit> much more efficient use of material when you make those parts separately. they used to make the nut and nipple together and you would lose 80% material
[07:33:05] <_methods> Tom_itx: here now
[07:33:06] <archivist> mostly made separate as one turns the other does not when fitting
[07:38:18] <witnit> its also nice you can have different fitting jobs and still run just one nut size. might be 4 different fittings @ 10,000 pcs and bam you automatically know they are gonna hit you with 40,000 of those nuts to go with them. so much less setup time involved
[07:38:41] <XXCoder> turret
[07:39:12] <witnit> yup yup
[07:51:28] <XXCoder> lol https://www.youtube.com/watch?v=CES7ozd-IOU
[07:51:37] <XXCoder> giant ... drinking? ... bird.
[07:55:45] <JT-Shop> had a rather large spider under my computer...
[07:55:53] <XXCoder> yummy
[08:04:41] <_methods> a blue one?
[08:11:13] <JT-Shop> no an 8 legged one
[08:11:35] <JT-Shop> well the air filters I rigged up on the desktop pc was slightly more effective than nothing
[08:13:23] <XXCoder> oh yeah
[08:13:30] <XXCoder> I need to do annual pc cleanup
[08:50:38] <pcw_home> on that encoder +- 80 arcseconds is ~ +- 280 counts so the 23 bit/turn is somewhat wishful thinking
[08:51:00] <pcw_home> is closer to a 15 bit encoder
[08:53:40] <pcw_home> still its very clever to have power harvesting for the multi turn counter ( also its not SSI, is 2.5 Mbaud async RS-485)
[08:54:52] <archivist> to me that suggests a minimum speed to generate
[08:55:39] <Duc> How woud I go about using a analog knob to set the jog speed? Looking to setup a switch to operator like a servo power drive on a manual mill
[08:55:48] <pcw_home> yeah you might be able to creep really slow and lose the turns count
[08:56:17] <pcw_home> probably not a practical issue
[08:58:20] <pcw_home> analog meaning pot or encoder? (pot is absolute, encoder most likely relative)
[08:59:09] <Duc> analog pot would be fine
[08:59:36] <Duc> just not sure what signal to tie the pot to in the hal file
[08:59:54] <pcw_home> what do you have for analog in?
[09:01:21] <Duc> either a 7i77 or 7i84
[09:02:29] <pcw_home> ok so you can just use a potentiometer tied to field power for that
[09:06:19] <Duc> would I send the signal into halui.jog.1.analog for each axis
[09:22:18] <pcw_home> probably halui.jog-speed for setting jog speed
[09:25:13] <pcw_home> ( unless you want to actually jog with the pot )
[09:25:21] <Duc> guess I missed that one
[09:25:41] <renesis> how do you jog with pot
[09:25:45] <Duc> nope just want to set the speed. I use the mill in manual mode alot for just cleaning up stuff
[09:26:05] <renesis> eheheh @ pot range = entire axis
[09:26:18] <pcw_home> man halui has the pin list
[09:26:51] <archivist> some use the digital jog wheels like http://www.ebay.co.uk/itm/400729450190
[09:27:58] <archivist> one day I want to get some
[09:28:40] <Duc> so much info that I forget each day. saved a webpage listing the pins man page
[09:29:40] <Duc> The jog wheels are nice but hard to get a constant speed with them
[09:40:03] * JT-Shop and Mrs. Shop take the BlueWing out for a ride with the biker gang
[09:40:37] <Tom_itx> don't get in any gang fights
[09:40:53] <Tom_itx> you roudy bunch you
[10:09:52] <MacGalempsy> good morning :)
[10:10:35] <MacGalempsy> http://www.ebay.com/itm/Light-Machines-SpectraLight-Model-200-Desktop-CNC-NC-Vertical-Machine-/122068547595?hash=item1c6bda380b:g:j2sAAOSwARZXn4IS
[10:10:43] <MacGalempsy> good deal if anyone is in Louisiana
[10:25:45] <zeeshan> XXCoder: you like the video i caught eh? :D
[10:27:07] <zeeshan> http://i.imgur.com/1y0oYbF.jpg
[10:27:08] <zeeshan> ROFL
[10:27:10] <MacGalempsy> i liked that destroying aluminum video
[10:27:18] <zeeshan> haha why
[10:27:21] <MacGalempsy> wtf
[10:27:41] <MacGalempsy> your voice. lol
[10:28:01] <zeeshan> https://www.youtube.com/watch?v=tjlsxqEZetw
[10:28:05] <zeeshan> this is the video im talking about
[10:28:09] <zeeshan> caught this dummy last night
[10:28:39] <MacGalempsy> link?
[10:29:39] <MacGalempsy> no racing vids?
[10:30:09] <MacGalempsy> lol what an idiot. Think he was drinking?
[10:31:04] <MacGalempsy> brb
[10:34:43] <zeeshan> nah
[10:34:47] <zeeshan> just being a dummy :P
[10:35:52] <Tom_itx> that you walking up to the car?
[10:35:59] <zeeshan> yes
[10:36:55] <Tom_itx> some do that on purpose
[10:37:05] <Tom_itx> to collect insurance money
[10:37:32] <Tom_itx> sometimes they have 2 vehicles in the caper
[10:37:33] <zeeshan> not this time :)
[10:37:46] <Tom_itx> i had 2 try that on me the other day but it didn't work
[10:37:48] <zeeshan> that poor corolla driver was shaking
[10:38:06] <zeeshan> my friend is trying to sell the video for me
[10:38:15] <zeeshan> hopefully i can get some money and get a rear cam too
[10:38:25] <zeeshan> or somehow manage into the toyota rear cam
[10:38:25] <Tom_itx> to who?
[10:38:38] <zeeshan> i think break.com
[10:39:50] <MacGalempsy> my sister was almost killed in an accident like that
[10:40:00] <MacGalempsy> 2 ppl setting her up on the interstate.
[10:40:21] <zeeshan> so stupid =/
[10:40:29] <zeeshan> arm yourself with a dashcam
[10:40:30] <zeeshan> they are cheap
[10:40:31] <zeeshan> like 55 usd
[10:40:34] <zeeshan> for a g1w
[10:40:43] <MacGalempsy> at some point the second car tried to file a claim, but was not at the accident report. then the cops told them they would arrest them for leaving the seen, so they withdrew the claim
[10:41:48] <MacGalempsy> later that car was stolen and the last pic was my brotherinlaw looking at a cut chassis on a crap trailer. they stripped EVERYTHING
[10:41:53] <MacGalempsy> like a 97 integra
[10:42:09] <MacGalempsy> but left the vin
[10:42:25] <archivist> note the passengers buggered off from the bad boys car
[10:42:45] <MacGalempsy> drugs or warrants
[10:44:10] <MacGalempsy> zeeshan: how is the shop going? last time I heard, you were setting up that lathe. is it up and running?
[10:44:36] <zeeshan> nah
[10:44:37] <zeeshan> this winter
[10:44:41] <zeeshan> been doing other stuff like fishing etc :D
[10:44:47] <zeeshan> and making parts and working onthe rx7
[10:46:01] <MacGalempsy> nice. what kind of parts?
[10:46:21] <zeeshan> vapes, car parts, rescue parts
[10:48:08] <MacGalempsy> vapes?
[10:50:27] <Tom_itx> smoker's vise
[10:51:16] <MacGalempsy> Ahhh. cool
[10:51:19] <MacGalempsy> pic?
[10:51:36] <zeeshan> not much pics :P
[10:51:57] <zeeshan> http://i.imgur.com/vAcLbiK.jpg
[10:52:01] <zeeshan> i will leave you with some vacation pics tho :D
[10:52:08] <zeeshan> http://i.imgur.com/KnqyzcB.jpg
[10:52:10] <MacGalempsy> haha. nice.
[10:52:21] <zeeshan> http://i.imgur.com/3YbVmlE.jpg
[10:52:21] <zeeshan> :D
[10:52:22] <MacGalempsy> we went to colorado a few weeks ago
[10:52:31] <MacGalempsy> catcha big fish?
[10:52:40] <zeeshan> mostly mackarel and perch
[10:52:41] <zeeshan> lol
[10:54:08] <MacGalempsy> a lot of fun.
[10:54:21] <CaptHindsight> zeeshan: how was the weather?
[10:54:40] <zeeshan> wet and partly cloudy :P
[10:54:45] <zeeshan> i still some how managed to get a tan
[10:54:49] <zeeshan> :{
[10:55:22] <MacGalempsy> cloud and on the water is the worst place to get a sunburn
[10:55:48] <MacGalempsy> because most people think the sun is filtered somehow
[10:56:51] <zeeshan> i shoulda wore sunblock
[10:56:56] <zeeshan> nice thing was that no bugs
[10:57:04] <zeeshan> very little bugs. suprising
[10:58:24] <MacGalempsy> was it ocean or lake fishing?
[10:59:52] <MacGalempsy> either way, the geology looks cool in that first pic
[11:00:11] <zeeshan> both
[11:00:21] <zeeshan> first pic is ocean
[11:00:39] <zeeshan> MacGalempsy: could you recommend me a book
[11:00:43] <zeeshan> that'll help me understand this:
[11:01:12] <MacGalempsy> the field is so big, what part do you want help better understanding?
[11:01:12] <zeeshan> http://www.mndm.gov.on.ca/mines/data/google/mrd126/Legend/MRD126Rev1_Legend.pdf
[11:01:22] <zeeshan> basically everything in this legend
[11:01:32] <zeeshan> first of all
[11:01:40] <zeeshan> why is a geological survey listed by era
[11:01:50] <zeeshan> and then wtf is a gabbro and diorite!
[11:02:06] <zeeshan> and what intrusive contact means
[11:02:10] <zeeshan> and supracrustal rocks
[11:02:10] <zeeshan> etc
[11:02:22] <zeeshan> i understand not one book will explain it all
[11:02:28] <MacGalempsy> ok. so the survey is listed by era because each geologic unit has been mapped and dated, probably with fossils
[11:02:30] <zeeshan> but im hoping there is some sort of bible like us mech eng have
[11:02:40] <zeeshan> that helps understand some of this
[11:03:02] <MacGalempsy> so since there is no finite way of dating things like . 1.532232million years old
[11:03:06] <zeeshan> MacGalempsy: when they do a survey like this and then i see an associated map
[11:03:17] <zeeshan> is it true that every spot on that map is really what they're saying it is
[11:03:28] <MacGalempsy> usually.
[11:04:11] <zeeshan> i really want to understand this legend :(
[11:04:17] <zeeshan> and the significance of these geological formations
[11:04:21] <MacGalempsy> the caviat is when you have a beach deposit next to a lagoon deposit. they look different but the fossils may indicate the same age
[11:04:40] <MacGalempsy> this is because at any given time, you have both depositional environments going on
[11:05:02] <MacGalempsy> gabbro is a mafic igneous rock
[11:05:15] <zeeshan> i have no idea what youre saying
[11:05:18] <zeeshan> i know what an igneous rock is
[11:05:19] <zeeshan> lol
[11:05:20] <MacGalempsy> I believe it is the same chem composition as basaly, but it has crystals
[11:05:25] <Tom_itx> hah
[11:05:35] <MacGalempsy> mafic is high iron content
[11:05:41] <zeeshan> ah
[11:05:48] <Tom_itx> mac must be a geologist
[11:05:52] <zeeshan> he is
[11:05:55] <zeeshan> :D
[11:06:00] <zeeshan> a smart one!
[11:06:04] <Tom_itx> for oil deposits?
[11:06:18] <MacGalempsy> that was my gig before unemployment last october
[11:06:26] <MacGalempsy> everyone quit drilling, so bye bye job
[11:06:27] <zeeshan> come up to canada
[11:06:32] <zeeshan> and find minerals!
[11:06:44] <MacGalempsy> actually, I am planning a mining trip to utah
[11:06:52] <Tom_itx> yeah i know a local one that has a similar story
[11:06:55] <MacGalempsy> we leave in the next few weeks. want to join? its for a month
[11:07:02] <CaptHindsight> I have oil deposits on my shop floor
[11:07:10] <zeeshan> MacGalempsy: too short notice :P
[11:07:12] <zeeshan> i started a new job :)
[11:07:19] <zeeshan> i'd LOVE to go on one
[11:07:23] <zeeshan> and bring equipment :P
[11:07:39] <zeeshan> i got my prospectors license up here in ontario
[11:07:45] <zeeshan> i'd like to go up for fun.
[11:07:47] <MacGalempsy> well. I applied for a job in Albuquerque with the geological survey
[11:08:04] <zeeshan> CaptHindsight: rofl
[11:08:06] <MacGalempsy> still havent heard back
[11:08:15] <zeeshan> don't give up hope
[11:08:20] <CaptHindsight> MacGalempsy: do you bring your own food, water and culture when you go to Utah?
[11:08:21] <zeeshan> geologists are a rare breed
[11:08:45] <MacGalempsy> CaptHindsight: the plan is to have about a week of rations. the spot I want to go is about 40 miles off the interstate
[11:08:52] <zeeshan> #1 rule of employment in this era
[11:08:54] <zeeshan> diversify
[11:09:17] <MacGalempsy> you got it
[11:09:35] <zeeshan> or be a union goat fkr :)
[11:09:45] <zeeshan> jk
[11:10:00] <MacGalempsy> now that my machine is up and running (except tool changer) i am going to try my luck with that
[11:10:21] <zeeshan> its your life, but i would honestly not give up your geological talents for machining
[11:10:26] <zeeshan> keep it on the side
[11:10:45] <MacGalempsy> we have about 12 months of savings left, so hopefully Trump will win and put Americans back to work
[11:10:49] <CaptHindsight> MacGalempsy: I want to spend some time below i70
[11:11:08] <zeeshan> he will win
[11:11:33] <zeeshan> MacGalempsy: theres gold up here
[11:11:35] <MacGalempsy> which one is i70?
[11:11:48] <zeeshan> i want to find a stream and pan and dredge
[11:12:07] <MacGalempsy> the spot I chose has gold, gemstones, and uranium
[11:12:14] <CaptHindsight> MacGalempsy: it's just north of Moab
[11:12:16] <MacGalempsy> I'd be happy with any of the three
[11:12:32] <CaptHindsight> Arches, Canyonlands etc
[11:12:40] <MacGalempsy> yeah, that is where I am going
[11:12:46] <MacGalempsy> to Beaver county utah
[11:12:52] <MacGalempsy> its closer to zion
[11:12:56] <zeeshan> MacGalempsy: does utah have a system that shows you their geology online
[11:12:58] <zeeshan> and claims
[11:13:02] <zeeshan> and land ownership
[11:13:05] <zeeshan> i love ontario for that
[11:13:08] <zeeshan> its all online or on google maps
[11:13:17] <MacGalempsy> yeah. I use an opensource software called qgis
[11:13:23] <zeeshan> so i can find a spot thru where other claims are, look at the geology
[11:13:24] <MacGalempsy> then look around for the data
[11:13:30] <zeeshan> then see if im intruding anyones land
[11:13:35] <zeeshan> luckily most land up here is crown land
[11:13:37] <MacGalempsy> dont just use maps though, you have to look for articles
[11:13:37] <zeeshan> meaning everyones land
[11:13:56] <zeeshan> articles?
[11:14:07] <MacGalempsy> for example. this one mine I was looking at has the wrong coordinates online, but when I found the article it was like 40miles away
[11:14:15] <MacGalempsy> articles = professional paper
[11:14:21] <zeeshan> ah
[11:14:35] <MacGalempsy> explore www.usgs.gov
[11:14:36] <zeeshan> a claim is dividing into hectares up here
[11:14:48] <zeeshan> divided
[11:15:10] <MacGalempsy> in the US we have Bureau of Land Management. you can basically look around on government land, then file a claim if you find anything
[11:15:27] <zeeshan> lots of gov land there?
[11:15:41] <MacGalempsy> like almost the whole state of Nevada is blm
[11:16:01] <MacGalempsy> https://www.google.com/search?q=map+of+us+blm+lands&tbm=isch&imgil=MjZcRtUtKZyTwM%253A%253B4HMPAeyPkxyR4M%253Bhttps%25253A%25252F%25252Fwww.hcn.org%25252Farticles%25252Fthe-taxpayer-money-behind-local-control-demands&source=iu&pf=m&fir=MjZcRtUtKZyTwM%253A%252C4HMPAeyPkxyR4M%252C_&usg=__hQ8ZWQzbHQTisBYMnE41PSOaEzE%3D&biw=1344&bih=740&ved=0ahUKEwjOkbLc06_OAhXETSYKHQ6jA5sQyjcIUA&ei=VFinV86XE8SbmQGOxo7YCQ#imgrc=MjZcRtUtKZyTwM%3A
[11:16:27] <MacGalempsy> all the red is pretty much open territory.
[11:18:01] <zeeshan> wow
[11:18:02] <zeeshan> thats a LOT
[11:18:10] <zeeshan> i didnt know usa was that undeveloped on those areas
[11:18:24] <zeeshan> so check this out
[11:18:24] <zeeshan> http://i.imgur.com/oPark8n.png
[11:18:29] <zeeshan> thats from claimmaps
[11:18:39] <zeeshan> so if i look up 4221421
[11:18:49] <zeeshan> http://i.imgur.com/M0ZWFzz.png
[11:18:50] <zeeshan> i get that
[11:19:08] <MacGalempsy> so 4221421 is the land unit
[11:19:15] <zeeshan> nahh that is the claim unit
[11:19:17] <MacGalempsy> and all those lists are mines in the unit
[11:19:18] <zeeshan> composed of 16 claims
[11:19:21] <MacGalempsy> ah
[11:19:29] <zeeshan> so then i can see what noront resources does
[11:19:34] <zeeshan> and i find out they mine for chrome
[11:19:35] <zeeshan> lol
[11:19:36] <zeeshan> chromite
[11:19:46] <zeeshan> then i compare it with the geological survey
[11:19:50] <zeeshan> and thats where i get lost :)
[11:20:07] <MacGalempsy> thats a good resourse. when I go mining, I take everything worth at least $20 on ebay :P
[11:20:21] <zeeshan> you need to spend a minimum of 400 per mining unit
[11:20:23] <zeeshan> to keep it active too
[11:20:33] <zeeshan> haha MacGalempsy
[11:20:39] <MacGalempsy> they do that at the BLM too. so think about claim jumping!
[11:20:57] <MacGalempsy> day after it expires, you file a claim. however, that is a good way to get murdered
[11:21:00] <zeeshan> yea it stops people from hogging claims
[11:21:12] <zeeshan> so like private land owners cant just say "yea im gfoing to be the under surface rights"
[11:21:15] <zeeshan> just to keep miners out
[11:21:39] <zeeshan> i would never claim jump
[11:21:47] <zeeshan> but i'd definitely buy the rights next to it :)
[11:21:53] <MacGalempsy> if it was a huge gold mine, I would
[11:22:12] <zeeshan> MacGalempsy: plz recommend me a book to learn or rear
[11:22:14] <zeeshan> read =[
[11:22:29] <MacGalempsy> so basically, you should start with an intro to geology book
[11:22:33] <zeeshan> yes
[11:23:01] <MacGalempsy> go to a campus bookstore and get the cheapest used intro book, not much changes
[11:23:13] <zeeshan> after reading that, i can understand that legend better?
[11:23:27] <MacGalempsy> then move onto a historical geology book, which will help you differentiate geologic time
[11:23:36] * zeeshan makes notes
[11:24:08] <MacGalempsy> then a mineralogy and petrology, then stratigraphy, and paleontology
[11:24:25] <MacGalempsy> those will help you identify rock composition and estimate age
[11:24:41] <MacGalempsy> finally read a field mapping book, and you should be set
[11:25:11] <MacGalempsy> oh! we should make some knock off brunton compasses on the cnc!
[11:25:35] <MacGalempsy> technically called a brunton pocket transit
[11:26:17] <MacGalempsy> http://www.brunton.com/products/conventional-pocket-transit-0-90
[11:26:19] <zeeshan> looks fancy
[11:26:33] <MacGalempsy> mine is old. like pre 1940, it looks the same
[11:26:45] <zeeshan> what do you use them for
[11:26:51] <CaptHindsight> so it's like math :)
[11:27:09] <MacGalempsy> http://www.brunton.com/products/axis-pocket-transit
[11:27:17] <MacGalempsy> watch this video about this new one
[11:27:51] <MacGalempsy> so you measure the rocks, write down the numbers on the map, then come back and draw up cross-sections
[11:28:01] <CaptHindsight> MacGalempsy: what do you drive when you are in the back country?
[11:28:35] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/8795788024/in/dateposted-public/
[11:28:49] <MacGalempsy> no ac or radio...
[11:29:14] <zeeshan> MacGalempsy: this is a dumb question
[11:29:19] <zeeshan> by why do you want to measure rocks
[11:29:41] <MacGalempsy> so you can do this https://www.youtube.com/watch?v=Vgo8Z63n60g
[11:30:09] <archivist> see what the strata is doing
[11:30:21] <MacGalempsy> if you have an rock going in the ground at an angle, you can project where that rock will be in the subsurface
[11:30:31] <zeeshan> MacGalempsy: doesnt a geologic survey map tell you this?
[11:30:40] <zeeshan> er
[11:30:44] <Tom_itx> who made the map???
[11:30:45] <archivist> someone has to make the map
[11:30:51] <MacGalempsy> geologic map is only plan view. cross-section is a profile view
[11:31:16] <zeeshan> so the survey map tells you where to look
[11:31:20] <MacGalempsy> you get a base topographic map. then walk around an area and draw in the contacts and measurements made with the compass
[11:31:32] <zeeshan> then you go find areas and map them
[11:31:36] <zeeshan> to narrow down to where youre looking for
[11:31:45] <zeeshan> *aht
[11:31:46] <zeeshan> dsajksadhas
[11:31:46] <MacGalempsy> that video is pretty good
[11:31:48] <zeeshan> *what
[11:32:01] <CaptHindsight> MacGalempsy: what series is that 40's?
[11:32:03] <MacGalempsy> exactly, especially if you are going to pay all that money to drill
[11:32:11] <MacGalempsy> CaptHindsight: yeah, 1970 model
[11:32:35] <zeeshan> MacGalempsy: will the intro to geology
[11:32:36] <zeeshan> cover this?
[11:32:42] <zeeshan> drawing a cross section
[11:32:52] * zeeshan wants to do things in order
[11:32:58] <MacGalempsy> a little. for the real class, it is called structural geology
[11:33:38] <MacGalempsy> fast forward that last video to 11:50
[11:33:51] <MacGalempsy> it shows them drawing in the geology
[11:35:12] <MacGalempsy> the cool thing is that if you had an underlying bed. in may not be expressed at the surface, but one can infer it is there. if it was gold bearing and under 10' of rock, then you can dig down and explore for it. but somewhere else that same rock maybe 100' below
[11:35:47] <zeeshan> ah
[11:35:55] <zeeshan> so easy to access vs imposible
[11:35:55] <zeeshan> :P
[11:36:11] <MacGalempsy> not impossible :P uneconomic!
[11:38:01] <zeeshan> geology formations are crazy :p
[11:40:00] <zeeshan> okay i gotta go, thanks for the convo! :P
[11:40:06] <zeeshan> definitely will be bothering you more in the future
[11:40:51] <MacGalempsy> later
[11:42:28] <archivist> zeeshan, start doing some ground thumping for really deep stuff
[11:43:18] <Sync> zeeshan: I like how handbag guy and gal are just casually leaving the scene
[11:44:31] <archivist> https://en.wikipedia.org/wiki/Seismic_source#/media/File:Thumper_trucks,_Noble_Energy.jpg
[11:44:45] <CaptHindsight> MacGalempsy: did you restore that one yourself? Diesel version?
[11:47:34] <MacGalempsy> CaptHindsight: it is petrol, as the diesel were not available in the US. I bought it and it was in decent shape the body was in good shape, I have done a bunch. Replaced a lot of electrical, had a new clutch, 2?" lift with 33" tires, manifolds, rebuild carb, new radiator.
[11:48:26] <MacGalempsy> the hardest part sometimes is finding a good quality replacement part. to find a transfer indicator switch took 1.5years
[11:48:35] <CaptHindsight> I have an 80 series that I'm working through
[11:48:54] <CaptHindsight> I use a Toyota dealer in NM
[11:49:08] <CaptHindsight> if the part is still in production
[11:49:19] <MacGalempsy> you use ih8mud.com?
[11:49:32] <CaptHindsight> yeah, Toyota Dan
[11:49:39] <MacGalempsy> thats u?
[11:49:48] <CaptHindsight> Cruiser Dan is the guy
[11:49:55] <MacGalempsy> ahhhhh....lol
[11:50:07] <CaptHindsight> he knows them in and out by part number
[11:50:25] <MacGalempsy> yeah...I was like, why is he taking it somewhere?
[11:51:05] <CaptHindsight> I've rebuilt everything so far except for the rear end
[11:51:21] <MacGalempsy> is that electronically locked?
[11:51:26] <CaptHindsight> yeah
[11:51:33] <MacGalempsy> you use a front locker too?
[11:52:07] <CaptHindsight> yeah
[11:52:20] <MacGalempsy> pic please
[11:52:54] <CaptHindsight> flip a switch and lock the transfer case, front and/or rear diffs
[11:53:21] <CaptHindsight> give me a minute
[11:55:44] <CaptHindsight> https://ibin.co/2qlPlA3eBmaS.jpg no longer has the mall cruiser rims
[11:56:17] <MacGalempsy> Looks toasty in the NM sun!
[11:56:23] <MacGalempsy> looks to be that is
[11:56:40] <CaptHindsight> you just crank up the AC :)
[11:57:04] <CaptHindsight> it's the straight 6, going to add a turbo
[11:57:29] <CaptHindsight> there is a bolt on supercharger available
[11:57:31] <MacGalempsy> sweet.
[11:58:16] <MacGalempsy> the bolt on would be elimit a new manifold
[11:58:22] <Sync> yeah the trd SC is ok
[11:58:44] <MacGalempsy> I think a sc would be better for a wheelin rig
[11:59:01] <CaptHindsight> https://ibin.co/2qlQjQ3iWOJ2.jpg when I first got it the head gasket was shot
[11:59:16] <CaptHindsight> so I pulled the engine and trans and rebuilt everything
[11:59:55] <MacGalempsy> you do all the machining on linuxcnc?
[12:01:23] <CaptHindsight> no, had just moved so I used a friend that's be doing engine machining for 30+ years
[12:01:51] <CaptHindsight> I have a pic of the front diff with 200K miles
[12:03:35] <MacGalempsy> have you made any cruiser parts on your cnc?
[12:04:07] <CaptHindsight> haven't had to make any
[12:04:18] <CaptHindsight> maybe for the turbo conversion
[12:05:02] <MacGalempsy> with as hard as some of that 40 stuff was to find, I have been on a mission to make some of the unobtainable replacement parts
[12:05:48] <CaptHindsight> https://ibin.co/2qlSmnvVpyf8.jpg drove to NY and back with just grease in the case
[12:06:32] <MacGalempsy> wow
[12:06:40] <CaptHindsight> I took it all apart and the bearings were fine
[12:07:02] <CaptHindsight> so I just readjusted everything and saved the bearings for a rebuild at 300k
[12:07:03] <MacGalempsy> are those metal specks?
[12:07:15] <CaptHindsight> just dust
[12:07:43] <CaptHindsight> was hardly anything stuck to the magnet on the drain plug
[12:08:47] <MacGalempsy> the odometer was stuck on mine at like 65ishk, but after cleaning it all up, I just reset it to 00000
[12:09:00] <MacGalempsy> now im at like 7k in 5 yrs
[12:09:54] <CaptHindsight> https://ibin.co/2qlTz713lvdm.jpg I don't drive it as much as I used to maybe 20K/year
[12:10:19] <MacGalempsy> by far the most impossible part to find was the interior dome light cover.
[12:11:08] <MacGalempsy> thats on my list of injection molds to make
[12:11:16] <CaptHindsight> interior parts and trim tend to disappear first
[12:12:07] <MacGalempsy> yep. there is a guy who sells a complete set of aluminum interior knobs for $250
[12:12:30] <MacGalempsy> they are black anodized with lettering pocketed into the face
[12:13:17] <CaptHindsight> sounds simple enough to make
[12:13:58] <MacGalempsy> yep, so I was thinking of using gridprobe to map out one of the knobs I have laying around, then cut a mold
[12:14:13] <CaptHindsight> there are some plastic end caps that hold the lead screw for the power seats, $40ea
[12:15:27] <MacGalempsy> yeah sor has a few things, but when you get to the older stuff, it is a gamble. Amazingly enough, I was able to find a new replica fuse box for only $60, but most stuff requires scrounging
[12:16:02] <CaptHindsight> I used to restore GM muscle cars from 62-74
[12:16:21] <MacGalempsy> nice
[12:16:37] <CaptHindsight> i stopped when the original parts were no longer available
[12:16:57] <CaptHindsight> most rebuilds now are out of repro catalogs
[12:17:41] <MacGalempsy> so what kind of stuff do you make in the shop now?
[12:19:18] <CaptHindsight> https://imagebin.ca/v/2TZ69LKPSZ6P multi-axis systems for materials deposition, custom machines, lab robots etc
[12:20:01] <MacGalempsy> I remember this pic, but didnt put it with your nick.
[12:20:39] <MacGalempsy> machines making more machines is so great
[12:20:49] <CaptHindsight> moving into machines and tools to make nano machines, DNA synthesizers
[12:21:23] <MacGalempsy> is it a full time job, or just a hobby?
[12:22:16] <CaptHindsight> both
[12:24:12] <MacGalempsy> very cool. it must be fun in your shop. What kind of big stuff do you have?
[12:24:12] <CaptHindsight> it's a hobby until I get paid
[12:25:19] <CaptHindsight> I don't use the big stuff as much. The news parts will all be <1um across
[12:25:27] <CaptHindsight> news/new
[12:26:21] <CaptHindsight> https://imagebin.ca/v/2RuHAsYVLA7N old pic
[12:27:27] <CaptHindsight> I mostly build things for guberment and university labs
[12:27:41] <CaptHindsight> that they take credit for
[12:29:58] <CaptHindsight> Utah is a nice place to visit but I wouldn't want to live there
[12:39:21] <CaptHindsight> http://www.pastebin.ca/3675819 starting with this hal file for hm2 servo with 7i77
[12:41:13] <CaptHindsight> ^^ from JT's http://gnipsel.com/linuxcnc/configs/7i77.html LinuxCNC 7i77 Tutorial
[12:43:33] <CaptHindsight> do you add or remove PID's in the THREADS section?
[12:44:06] <CaptHindsight> addf pid.0.do-pid-calcs servo-thread (for example)
[13:08:32] <plpower> hi someone knowes if there is a parameter inside a dxf that vontroles the value from a scaled part
[13:08:58] <plpower> i see half mesurment values on a 2:1 file
[13:10:38] <archivist> the dxf spec is online somewhere
[13:11:23] <archivist> http://www.autodesk.com/techpubs/autocad/acadr14/dxf/dxf_reference.htm
[13:11:53] <plpower> i saw that and edit alot iside but nothing helped
[13:32:35] <mmachines> I'm tuning my config .ini, and .hal manually from an example starting point (pncconf did not work for my setup)
[13:32:43] <mmachines> it is basically working
[13:33:23] <mmachines> my physical e-stop does not feedback to the AXIS UI - I assume I want it to?
[13:33:48] <mmachines> the e-stop is signal: net abort <= hm2_5i25.0.gpio.003.in
[13:33:56] <mmachines> and halmeter shows it toggles correctly
[13:34:14] <mmachines> but not sure how to connect to UI yet
[13:35:39] <mmachines> I also have these lines:
[13:35:46] <mmachines> net estop-out <= iocontrol.0.user-enable-out
[13:35:52] <mmachines> net estop-out => iocontrol.0.emc-enable-in
[13:40:09] <plpower> mmachines: why not connect to halui estop
[13:40:17] <plpower> simple as it can be
[13:40:24] <plpower> bo estop chain issue
[13:41:24] <plpower> there you also can deside if yooour estop simlply stops the motion only
[13:41:32] <plpower> not the mashine
[13:41:42] <plpower> and or mashine esop at all
[13:41:54] <plpower> see halui section in the manual
[13:42:30] <mmachines> plpower: thanks for the pointer, I will check it
[13:46:12] <plpower> mmachines: http://www.linuxcnc.org/docs/2.7/html/gui/halui.html
[13:47:16] <plpower> net abort hm2_5i25.0.gpio.003.in => halui.estop.activate
[13:48:49] <plpower> mmachines: question why not using a simple parport interface card insted of the 5i25
[13:49:30] <plpower> 5i25 is faster and realy good but not cheep as a simple 10USD printer PCI
[13:51:17] <mmachines> plpower: OK maybe a parport would have worked too. this is my first machine and I understand there were advantages to the 5i25 (actually I'm using the 6i25 but it appears as 5i25)
[13:52:00] <plpower> agree here i got also 5i26 but 7i76 on it for realy massic IO
[13:52:21] <plpower> as all limits seperate
[13:52:31] <plpower> probing torch control .....
[13:54:44] <plpower> mmachines: net abort on e-stop is not the right NAME spelling ;-)
[13:54:58] <plpower> external_Estop
[13:55:14] <plpower> Estopswitchbutton
[13:55:28] <plpower> ad so on
[13:55:38] <plpower> as abort is used for clearing errors
[13:55:51] <plpower> on the pendand
[13:56:02] <plpower> Hand held control
[13:57:00] <mmachines> plpower: OK "abort" is not the right name convention? it came from my reference config will change to "external_Estop"
[13:57:35] <plpower> up to You name it HUHO if you like
[14:02:16] <mmachines> now external e-stop status is reflected in the AXIS UI
[14:02:43] <mmachines> but if I start linuxcnc when e-stop is active I can still turn machine on?
[14:03:29] <mmachines> nevermind - when I turn the machine on it clears the e-stop which I think is correct
[14:05:33] <mmachines> if the physical e-stop is ON I should not be able to Toggle Emergency Stop in the UI - correct?
[14:10:52] <plpower> e-stop chain is a triggi part
[14:11:31] <plpower> and estop external is not to be uset to power off the intire mashie
[14:11:50] <plpower> im off need to get some sleep hard week ahad
[14:15:18] <mmachines> I will try the estop_latch component example http://gnipsel.com/linuxcnc/configs/external-estop.html

[14:48:53] <dioz> does eastwood make good welders?
[14:55:39] <alex4nder> no
[14:55:59] <alex4nder> eastwood rebadges shitty chinese welders
[14:56:48] <dioz> they seem kind of inexpensive
[14:56:52] <dioz> i mean compared to a red or blue that is
[14:56:59] <alex4nder> haha you trolling again?
[14:57:09] <dioz> i just notice they have a pretty good youtube channel
[14:57:33] <dioz> there's also this dude i watch on youtube
[14:57:35] <dioz> he's a fabricator
[14:58:50] <dioz> https://www.youtube.com/user/ChuckE2009
[14:58:51] <dioz> that guy
[14:58:57] <witnit> those dont weld galvanized
[14:58:58] <dioz> and he seems to think they're okay
[14:59:08] <alex4nder> witnit: nothing can weld galvanized
[14:59:11] <witnit> *snickers*
[14:59:14] <alex4nder> not even jet fuel
[14:59:18] <witnit> trololol
[15:05:58] <dioz> i'll break your stinger hand
[15:06:29] <dioz> my cousin (big guy) he used to do industrial pipe-line and i went and worked for him for a season
[15:06:55] <dioz> anyways we were at the pealer bar and idk what happened but i heard my cousin say that to a dude
[15:07:03] <dioz> "i'll break your stinger hand"
[15:07:16] <dioz> my cousin was about 7 feet tall an weighed about 270 pounds
[15:07:28] <dioz> he was a beast of a man
[15:07:49] <Duc> this fucking again
[15:08:14] <Duc> but on a good side note - got 3k cash for the techno cnc router
[15:10:14] <dioz> fuckin asked the gf to bring me home some liquor
[15:10:17] <dioz> what does she bring me?
[15:10:19] <dioz> MALIBU
[15:10:27] <dioz> 20%
[15:32:25] <witnit> typical
[15:32:43] <witnit> I wonder if you can weld galvanized with salt
[15:39:33] <dioz> idk how but i heard it's better to use kool-aid
[15:45:58] <Tom_itx> Jymmm Jymmm!!!!!
[16:01:41] <JT-Shop> that was a nice ride
[16:06:29] <XXCoder> zeeshan: lol
[16:27:00] <jdh> JT: what did you ride?
[16:36:24] <JT-Shop> the BlueWing
[16:37:32] <JT-Shop> I had bangers and mash for lunch
[16:44:12] <Deejay> gn8
[16:44:27] <CaptHindsight> JT-Shop: did you have Spotted Dick for dessert?
[16:46:14] <JT-Shop> no dessert
[16:46:27] <JT-Shop> didn't see bubbles and squeak on the menu either
[17:28:57] <Jymmm> Tom_itx: Yes Sir?
[17:34:08] <Crom> finally found some molex extension cable which I'm going to use to connect my TB6600 drivers to the bad bulkhead connectors. I'll cut them in half, probably more like 1/3,2/3. So I can take off the lid with the tb6600's mounted on it. I also found some JST xh female,female patch cables to go from the BOB to the driver boards.
[17:34:17] <Crom> s/bad/back/
[17:36:10] <Crom> I'm replacing the screw terminals on the driver boards with some plug in terminals so I can unplug power as required
[17:37:16] <tiwake> how many of you guys drink at all?
[17:37:30] <Tom_itx> i drink water
[17:37:39] <tiwake> alcohol :P
[17:39:37] <tiwake> I kind of suspect that of all the professions, machinists might drink less on average than most other professions... but I don't have much data to go off of
[17:51:30] <JT-Shop> I'll drink to that
[17:57:00] <JT-Shop> anyone make pickles?
[17:57:58] <Tom_itx> not lately
[17:58:26] <JT-Shop> we have a bunch of cucumbers so time to make pickles
[17:58:41] <Tom_itx> grow your own dill
[17:58:56] <JT-Shop> dill didn't do so well for some reason
[17:59:29] <Tom_itx> i had a bread n butter recipe somewhere the neighbor gave us but i dunno where it went
[18:01:15] <JT-Shop> I don't eat pickles so I have no clue what tastes like what lol
[18:01:57] <JT-Shop> but I have expanded my taste to like homemade sauerkraut
[18:02:00] <Tom_itx> that one didn't take very long for them to become ready unlike some that need to sit quite a while
[18:02:10] <JT-Shop> so I'm not ruling homemade pickles out
[18:17:14] <CaptHindsight> the pncconfig output is giving me a headache, how it creates the HAL is different from most of the hand written configs
[18:17:46] <JT-Shop> stepper or servo?
[18:17:51] <CaptHindsight> servo
[18:17:58] <CaptHindsight> here's yours http://www.pastebin.ca/3676300
[18:18:09] <JT-Shop> afaik it does a pretty good job
[18:18:13] <CaptHindsight> now let me get the one pncconfig generated
[18:18:39] <CaptHindsight> it's not clean simple like yours
[18:18:54] <JT-Shop> no it's not
[18:19:00] <CaptHindsight> it's spreads connections all over the place
[18:22:56] <CaptHindsight> what pncconfig does http://www.pastebin.ca/3676314
[18:25:06] <JT-Shop> I know what it does
[18:26:15] <CaptHindsight> since my XY servos don't come in contact with anything they don't need a PID
[18:26:37] <Crom> i drink tea, milk, squirt, and if I have too water
[18:28:46] <CaptHindsight> water is pretty handy
[18:29:13] <CaptHindsight> you can drink it, bathe in it, and freeze it etc
[18:29:46] <tiwake> CaptHindsight: one of the best solvents in existence
[18:30:02] <tiwake> or maybe it is the best solvent
[18:30:41] <CaptHindsight> you can even build a house with it
[18:30:56] <XXCoder> with what? heh missed
[18:31:01] <tiwake> XXCoder: water
[18:31:16] <XXCoder> hm yeah thats possible in certain regions heh
[18:31:22] <tiwake> CaptHindsight: can cut stuff with it
[18:32:09] <tiwake> though I don't think its biodegradable
[18:32:22] <CaptHindsight> it can also be a cloud
[18:32:29] <XXCoder> its hell of a powerful solvent
[18:32:32] <XXCoder> one of most powerful
[18:32:53] <tiwake> XXCoder: already said that :P
[18:34:33] <tiwake> hmm
[18:35:00] <tiwake> one of the most fun substances to play in
[18:35:17] <tiwake> I cant think of anything else
[18:35:31] <XXCoder> just be glad its solid form floats on liquid form
[18:35:39] <XXCoder> otherwise life'd be not possible
[18:35:51] <CaptHindsight> I wonder long it would take a person to dissolve in a pool of Diet Coke?
[18:36:16] <tiwake> how acidic is it?
[18:36:46] <CaptHindsight> http://www.sheltondentistry.com/patient-information/ph-values-common-drinks/
[18:36:51] <tiwake> CaptHindsight: completely? or dissolve enough to just die?
[18:37:31] <CaptHindsight> ph of Coca-Cola 2.52
[18:38:13] <tiwake> CaptHindsight: thats about the same ph level of stomach acid
[18:38:22] <tiwake> so maybe 3ish days?
[18:38:29] <tiwake> 2?
[18:38:31] <CaptHindsight> Stomach Acid 1.50-3.50
[18:38:50] <tiwake> depends on if you took some tums or not
[18:38:51] <tiwake> :P
[18:39:05] <CaptHindsight> Diet Coke 3.28 is better for you
[18:39:06] <tiwake> breads are basic
[18:39:44] <CaptHindsight> how many tums to neutralize 10K gallons of regular Coke?
[18:40:01] <tiwake> what? lol
[18:41:08] <CaptHindsight> so a person would have maybe a few hours to escape from a pool of Coke tops
[18:41:20] <tiwake> I'm gonna cook some broccoli
[18:42:24] <tiwake> CaptHindsight: oh, if said person fell into it willy wonka chocolate factory style?
[18:42:28] <CaptHindsight> a bit longer if covered in Tums
[18:42:45] <CaptHindsight> heh, yeah
[18:43:33] <CaptHindsight> have to post the Coke vs skin test challenge
[18:43:52] <CaptHindsight> I'm sure there will be a youtube within a week
[18:44:18] <CaptHindsight> hand soaked in Coke after 15 minutes, 1 hour etc
[18:44:21] <tiwake> see how long it takes to burn a hole through a small patch of skin
[18:45:06] <CaptHindsight> never knew that regular Coke was that acidic
[18:45:24] <CaptHindsight> just short of lemons
[18:45:49] <CaptHindsight> maybe make a Coke and copper battery
[18:46:52] <tiwake> that should be a thing in minecraft
[18:47:26] <tiwake> how many cokes of electricity a device consumes per tic
[18:48:09] <CaptHindsight> back to trying to get the open loop stepper settings right
[18:48:18] <tiwake> lol
[18:48:30] <tiwake> another 15min and I'm going to take off
[18:48:46] <JT-Shop> I thought it was an open loop servo
[18:49:02] <CaptHindsight> yeah servo not stepper'
[18:49:12] <CaptHindsight> see my mind is going
[18:49:29] <tiwake> CaptHindsight: its biodegradable
[18:49:52] <CaptHindsight> wasn't too concerned about it leaving a mess
[18:53:09] <tiwake> heh
[20:05:39] <mmachines> I have two motors for y; in the .hal example I'm referencing (hostmot2) one joint is control-type 1 and the tandem is control-type 0
[20:05:58] <mmachines> is that correct? shouldn't both be velocity? or is this normal config?
[20:13:17] <mmachines> part of .hal for example: https://gist.github.com/anonymous/774e380c25d726127c8ca1911a5a50dd
[20:13:36] <mmachines> setp hm2_5i25.0.stepgen.01.control-type 1
[20:13:45] <mmachines> setp hm2_5i25.0.stepgen.03.control-type 0
[20:14:18] <mmachines> I have not split JOINT_1 into two separate joints but I think that also should be done
[20:15:17] <dioz> i need to seperate a bunch of rock from dirt
[20:28:47] <CaptHindsight> what IRC client works with the latest Linuxcnc ISO?
[20:29:08] <CaptHindsight> xchat is broken
[20:30:46] <renesis> irssi
[20:30:58] <zeeshan> jeez that dashcam video has gotten almost 4k views
[20:31:04] <zeeshan> still not 24hrs!
[20:31:05] <renesis> screen(1) + irssi = real ultimate power
[20:31:15] <dioz> tmux
[20:31:18] <dioz> ;]
[20:31:22] <dioz> jk i'm a screen user
[20:31:37] <renesis> i dunno what tmux is but if it means terminal mux, neat
[20:31:46] <dioz> terminal multiplexor
[20:31:51] <dioz> same thing as screen
[20:31:54] <dioz> but newer
[20:32:04] <renesis> oh right, sorry my brain just translates mux
[20:32:21] <renesis> yeah because screen is some dinosaur shit
[20:33:23] <dioz> it is
[20:34:42] <renesis> the swedes i learnt a lot of the lunix from use weechat now
[20:43:22] <BeachBumPete> Evening folks
[20:43:55] <SpeedEvil> Screen is awesome
[20:44:05] <BeachBumPete> anyone mind looking at some photos of my breaker panel and give me some ideas about what I should do for power?
[20:44:23] <BeachBumPete> what screen?
[20:44:26] <malcom2073> BeachBumPete: Get more of it
[20:44:32] <MrHindsight> I can't find a graphical IRC client that works with this Wheezy install
[20:44:39] <BeachBumPete> har har
[20:44:42] <XXCoder> MrHindsight: xfce?
[20:44:53] <malcom2073> MrHindsight: Get demoted?
[20:44:53] <MrHindsight> XXCoder: yeah
[20:44:58] <XXCoder> MrHindsight: oops heh I meant hexchat
[20:45:07] <XXCoder> I thought you meant desktop manager lol
[20:45:19] <MrHindsight> graphical IRC client
[20:45:24] <MrHindsight> oh well
[20:45:48] <MrHindsight> malcom2073: different machine, different nick
[20:46:45] <XXCoder> MrHindsight: it is gui window irc chat
[20:51:37] <MrHindsight> Linuxcnc error hal:54 Pin "x-pos-cmd' does not exist
[20:52:23] <MrHindsight> http://www.pastebin.ca/3676567
[20:53:57] <MrHindsight> x-pos-cmd is there a few lines later
[20:54:06] <MrHindsight> does order matter?
[20:54:48] <MrHindsight> I want to loop back FB position to commanded position
[20:59:28] <CaptHindsight> how does scaling factor into an open loop servo since there is no encoder
[21:00:29] <renesis> graphical irc clients are all shit
[21:01:01] <malcom2073> So are telephones, electricity, and shoes.
[21:05:28] <BeachBumPete> http://imgur.com/a/wVlcn well here are the pictures in case anyone is interested. I need to either remove that 20 amp 220v breaker for the nonexistant water pump that was there when the house had a well at some point or replace the entire panelwith one that has more room inside it.
[21:08:48] <pcw_home> x-pos-cmd is a signal (so must be the first token after the net command)
[21:09:37] <pcw_home> only OUTPUT_SCALE matters if you have no feedback device
[21:12:02] <CaptHindsight> I have to read the HAL definitions again
[21:13:00] <CaptHindsight> is x-pos-fb not a signal?
[21:13:44] <CaptHindsight> should this HAL line be reversed? net x-pos-fb => x-pos-cmd
[21:14:16] <CaptHindsight> net X-pos-cmd => x-pos-fb
[21:19:56] <CaptHindsight> it actually runs with that line commented out
[21:20:12] <CaptHindsight> but the scale is off
[21:20:30] <CaptHindsight> galvos are moving
[21:22:32] <Tom_itx> damn he left just as i was looking at his post
[21:23:07] <Tom_itx> looks like a SquareD pannel to me
[21:23:57] <CaptHindsight> " net Xpos-cmd axis.0.motor-pos-cmd " connects those 2 signals
[21:32:12] <Tom_itx> run a scale between the net and the signal
[21:34:51] <Crom> I hate Square D panels, as well as GE panels.. Murray panels with BR breakers ROCK!
[21:35:50] <Wolf_> that doesn’t look like a square D
[21:36:39] <Tom_itx> maybe my old one was something else then but i though it was
[21:36:39] <Crom> I've had to put a panel between the meter and the main panel (GE) to get modern breakers for electrical stuff outside.
[21:36:43] <Tom_itx> they sure look similar
[21:36:50] <Wolf_> pretty sure that same panel is in my mom’s house tho, like a 1964 built house
[21:37:46] <Tom_itx> where the heck did JT hide the comp list in the docs... i can't seem to find anything since it was updated. nothing against JT-Shop i think he did a great job...
[21:37:54] <CaptHindsight> some breakers are labeled SquareD
[21:38:28] <CaptHindsight> but if you really want to find a matching breaker you need to show the bus and the way the breaker locks into the panel
[21:38:29] <Tom_itx> ahh there it is..
[21:38:39] <Crom> it's either a Challenger or SquareD panel
[21:38:40] <Wolf_> oh yeah I see that now, HOM type
[21:38:53] <Tom_itx> maybe they were interchangeable
[21:39:21] <Tom_itx> http://linuxcnc.org/docs/2.7/html/man/man9/scale.9.html
[21:39:32] <Tom_itx> CaptHindsight, put that between your signal and net
[21:39:41] <CaptHindsight> hw should have pulled one break and taken a pic of the bus and the backside of the breaker
[21:40:11] <CaptHindsight> Tom_itx: will try but I'd really like to fully understand HAL vs trial and error
[21:40:27] <Tom_itx> why is your scale off?
[21:41:02] <Crom> Hmm Q115 breaker... that looks like Challenger.. That Squard D breaker is a TIPO
[21:41:32] <CaptHindsight> Tom_itx: how the whole HAL file works, how can you tell whats a pin vs signal?
[21:41:33] <Tom_itx> well either way it's awfully crouded
[21:42:40] <Crom> ahhh Siemens... QP type..
[21:42:49] <CaptHindsight> wow they entered the panel at the bottom and didn't flip the panel
[21:43:22] <Wolf_> lol I noticed the entry mess up as well, QP type I think is what is at my mom’s house lol
[21:43:56] <Wolf_> I do remember it being a pain in the ass to find breakers for it
[21:44:17] <CaptHindsight> he's got room, he just needs to change a few breakers to 2 per space types
[21:44:33] <Tom_itx> CaptHindsight i think one way is most pins will have a number of sorts associated with them
[21:44:54] <Tom_itx> ie ...gpio.002
[21:45:01] <Wolf_> or take out the 20A 220 grinder/pump breaker and run the sub off that slot
[21:45:03] <pcw_home> you dont actually need "scale"
[21:45:20] <Tom_itx> or ...stepgen.00.xxx
[21:45:23] <CaptHindsight> Tom_itx: if I had written HAL I would have made it obvious in some way, maybe it is but I don't see it yet
[21:45:30] <Crom> http://www.homedepot.com/b/Electrical-Power-Distribution-Circuit-Breakers-Tandem-Breakers/Siemens/N-5yc1vZbm0fZ1z0mi4g
[21:45:37] <mmachines> Machine->Show Hal Configuration - will show pins vs signals
[21:45:56] <Crom> all those single 15's and 20's can be replaced with Q1515NC and Q2020NC
[21:45:56] <pcw_home> (the analog outputs are scalable)
[21:46:02] <Tom_itx> oh
[21:46:26] <Tom_itx> i wasn't quite sure what he was doing
[21:46:39] <Tom_itx> whether it was a pulse or just what
[21:46:41] <CaptHindsight> I wish it was obvious but just looking at them vs having to generate a chart/list
[21:46:45] <pcw_home> signals are the token after the net command
[21:46:59] <pcw_home> pins are any later tokens
[21:48:18] <pcw_home> signals are also rather magic as they are created as needed (but pins are only created by components/linuxcnc modules/drivers)
[21:48:36] <CaptHindsight> in this example: net x-pos-fb is x-pos-fb a signal? what prevents you from using a pin name?
[21:48:44] <Tom_itx> yes
[21:48:55] <pcw_home> the first token after net must be a signal
[21:49:05] <Tom_itx> you would assign a pin or such to that
[21:49:36] <Crom> ack beachbum left...
[21:49:42] <pcw_home> it cannot be a pin
[21:50:22] <CaptHindsight> if you follow the proper syntax
[21:50:57] <Tom_itx> they used => <= arrows for the user in the past but linuxcnc never really looks for those
[21:51:02] <pcw_home> though I guess its arguable that it would be nice to have
[21:51:04] <pcw_home> net pinx piny pinz and for the parser to create an invisible signal
[21:51:51] <pcw_home> for those case you dont need the signal elsewhere in the hal file or in other hal files
[21:51:56] <CaptHindsight> I'm just looking at it again after a long hiatus and I can't tell whats a pin and whats a signal
[21:51:57] <pcw_home> cases
[21:52:24] <CaptHindsight> I'm just hoping that whats there has been written correctly in the examples
[21:52:41] <pcw_home> you cant unless you do halcmd show pin or halcmd show signal
[21:53:03] <pcw_home> also signal names can be anything
[21:53:13] <CaptHindsight> I see that now
[21:53:30] <CaptHindsight> you wouldn't have to if it was made obvious by syntax
[21:53:40] <pcw_home> It is
[21:54:10] <CaptHindsight> if a signal follows the net token
[21:54:14] <pcw_home> net signal pin pin pin pin
[21:54:36] <pcw_home> it has to
[21:54:43] <CaptHindsight> that is how it's always supposed to be done
[21:54:44] <CaptHindsight> ok
[21:54:50] <pcw_home> anything else is an error
[21:56:01] <CaptHindsight> I didn't notice that in the HAL manual
[21:56:35] <pcw_home> though as I said before it might be nice if the parser noticed that the first token was a pin and created an invisible signal
[21:56:43] <Tom_itx> i learned by example and asking here alot in the beginning
[21:57:02] <CaptHindsight> I try to forget :)
[21:58:09] <CaptHindsight> just seeing net signal pin pin pin ... helps
[21:59:29] <pcw_home> also you can only have one source (output) pin per signal
[21:59:44] <pcw_home> (with the exception of I/O pins)
[22:01:04] <pcw_home> if you do halcmd show all you get a list of all the pins, parameters, signals, functions, and threads
[22:01:05] <pcw_home> and the direction of all the pins
[22:01:35] <mmachines> using 6i25 with open loop steppers (and gecko g540); for hostmot2 stepgen I understand there are two control modes velocity and position
[22:01:59] <CaptHindsight> the galvo moves but it looks like it reaches maximum travel maybe 1/10 earlier than needed
[22:02:46] <mmachines> does the choice of velocity control mode mean that I use loadrt pid?
[22:02:53] <pcw_home> so you need to tweak OUTPUT_SCALE
[22:03:08] <CaptHindsight> it's at 10 currently
[22:03:34] <CaptHindsight> output_min_limit is -5V
[22:03:44] <CaptHindsight> output_max_limit is 5V
[22:03:50] <pcw_home> if 10V = 10 inches (or 10 mm) thats correct
[22:04:47] <CaptHindsight> so for 10V = 100mm the scale should be 100
[22:05:20] <pcw_home> yes
[22:05:21] <pcw_home> you actually need cosecant^2 correction
[22:06:21] <pcw_home> (with OUTPUT_SCALE=100 the limits need to be set to +-100 if you want to go to 10V)
[22:08:58] <CaptHindsight> yeah it was only swinging 1V
[22:12:20] <CaptHindsight> looks like my scale should be +-50 to limit it to +-5V
[22:17:04] <CaptHindsight> the correction is done in the galvo driver as well as under/overshoot
[22:17:35] <CaptHindsight> vs acceleration
[22:19:17] <CaptHindsight> these drivers are old cheapies, the ones coming have encoder feedback and have <10 uRad res and repeatability
[22:46:23] <tolland> what does DQ refer to on a cnc machine?
[22:52:58] <XXCoder> https://www.youtube.com/watch?v=abVqj2OE3po interesting
[22:53:29] <roycroft> it means it's a cnc ice cream cone machine
[22:53:52] <XXCoder> "Damn quick"
[22:53:56] <XXCoder> dunno actual
[23:23:22] <MacGalempsy> alright. just got a gcode program together for a series of drills and pockets. time to type it into a file and measure some tools lengths and diameters.
