[00:00:01] <fenugrec> cocky
[00:00:02] <ssi> they're pretty trivial to make
[00:00:34] <fenugrec> hmm, never really investigated. You must have a temperature-controlled something in there, no ?
[00:00:40] <ssi> yeah, it's pretty simple
[00:00:56] <ssi> the nozzle itself is brass, and there's a hole drilled through the block at the end with a 2W resistor through it
[00:00:57] <fenugrec> do you PID the heating coil ?
[00:00:59] <ssi> yes
[00:01:06] <ssi> there's a thermistor in the block as well
[00:01:09] <fenugrec> smart man
[00:01:19] <ssi> gotta maintain pretty consistent temp
[00:01:38] <fenugrec> yeah, anything else and you get clogging or "leaks", I suppose
[00:01:57] <ssi> well there's a pretty narrow glass transition window
[00:02:19] <fenugrec> ok
[00:02:32] <ssi> anyway, I'm not the smart man
[00:02:41] <ssi> I'm certainly standing on the shoulders of at least tall dudes
[00:02:51] <fenugrec> (hahaa I've been just doing some "M6 Txx" for the past 10 minutes, enjoying some ATC magic)
[00:02:56] <ssi> :)
[00:03:31] <ssi> http://www.prototechnical.com/~imcmahon/repetier.png
[00:03:37] <ssi> the temp graph display
[00:03:41] <ssi> showing the pid-controlled nozzle and bed temps
[00:04:42] <ssi> for a resistor, a thermistor, and arduino software driving a mosfet, it does a surprisingly good job
[00:04:48] <fenugrec> nice. "Fan", is the nozzle fan-cooled ?
[00:04:57] <ssi> it can be
[00:05:00] <ssi> I don't have a fan on mine
[00:05:00] <fenugrec> or does it cool down naturally only
[00:05:10] <ssi> mine cools naturally
[00:05:13] <ssi> happens pretty quick
[00:05:23] <fenugrec> hmm, that makes the PID a bit more finnicky I guess - reacts asymetrically
[00:05:37] <ssi> well I mean the filament as it extrudes into free air cools quick
[00:05:41] <ssi> you don't want the nozzle to be cooled
[00:05:42] <fenugrec> but it looks convincing on the graph.
[00:05:52] <fenugrec> I see
[00:05:58] <ssi> it's just pwming the nozzle resistor to keep it at temp
[00:05:59] <ssi> pid works well
[00:06:05] <ssi> the fan is for cooling the part as it's printed
[00:06:10] <fenugrec> okok
[00:06:12] <ssi> but getting all that stuff right is tough
[00:06:14] <fenugrec> and bed ?
[00:06:18] <ssi> bed has to be hot for the part to adhere
[00:06:33] <fenugrec> ah, right.
[00:06:34] <ssi> as soon as the bed cools below 60C or so, the part pops right off
[00:06:46] <ssi> adherence is the biggest issue with these things
[00:06:58] <fenugrec> speaking of beds... I'm outta here.
[00:07:01] <ssi> gnite
[00:07:08] <fenugrec> cya
[00:09:54] <zeeshan> ssi
[00:09:57] <zeeshan> do you have a cnc mill
[00:11:40] <ssi> not a complete one
[00:11:51] <zeeshan> im thinking about converting the bridgeport clone
[00:11:52] <zeeshan> to cnc
[00:11:57] <zeeshan> i dunno if it's worth it
[00:12:00] <zeeshan> its r8 =/
[00:12:02] <ssi> eh
[00:12:07] <ssi> I have a bridgeport clone as well
[00:12:10] <zeeshan> no atc would suck.. on a cnc mill
[00:12:12] <ssi> and I haven't really wanted to do that either
[00:12:14] <ssi> because r8
[00:12:18] <ssi> and because it's a GREAT manual mill
[00:12:23] <ssi> and because it's got too many movements
[00:12:31] <zeeshan> what do you mean
[00:12:35] <zeeshan> too many movements
[00:12:37] <ssi> ram travel, ram angle, head twist, head nod, knee, quill, etc
[00:12:43] <ssi> so many things to keep aligned and trammed
[00:12:43] <zeeshan> thats okay
[00:12:49] <ssi> to make cnc less repeatable
[00:12:59] <zeeshan> all good machines allow you to move those angles/movements
[00:12:59] <ssi> it's just a better manual mill
[00:13:02] <zeeshan> during spindle crash
[00:13:21] <ssi> if I had two of them I might consider it
[00:13:30] <ssi> but I'd want to try to find a bt20 spindle for it or something
[00:13:35] <zeeshan> my biggest drawback is R8 so far..
[00:13:43] <zeeshan> i got quoted for a iso30 spindle..
[00:13:45] <zeeshan> $1000
[00:13:46] <zeeshan> :{
[00:13:55] <ssi> what I really want to do is get something like a cinci 500 like pete's got
[00:14:01] <ssi> but I'm running out of space
[00:14:08] <zeeshan> i cant fit any of those machines in my garage
[00:14:13] <ssi> I'm not sure I can either
[00:14:17] <zeeshan> 7.7' ceilings
[00:14:25] <zeeshan> plus theyre expensive in canada
[00:14:30] <zeeshan> even when they're blown up
[00:14:38] <ssi> I want something that's light enough that I can move it with my forklift
[00:14:45] <ssi> and I'm not sure there's a vmc alive that is under 5j
[00:14:47] <ssi> 5k
[00:15:02] <zeeshan> theres gotta be a way
[00:15:05] <zeeshan> to do atc on r8
[00:15:12] <ssi> TTS
[00:15:17] <zeeshan> other than that :P
[00:15:18] <anarchos_> r8->tts
[00:15:22] <ssi> that's what I was planning on doing with my g0704
[00:15:29] <zeeshan> where would you put all your tools?
[00:15:35] <zeeshan> would you make some sort of overhanging unit
[00:15:36] <ssi> in a rack at the far end of travel
[00:15:37] <zeeshan> that holds all the tools?
[00:15:39] <zeeshan> ah
[00:15:42] <ssi> or do a carousel that swings in like hoss
[00:15:44] <ssi> there's a few options
[00:15:55] <anarchos_> yeah i want to do a hoss style one, i think
[00:16:00] <ssi> not great options, but options
[00:16:04] <zeeshan> whats the largest shank on the tts
[00:16:05] <zeeshan> 3/4"?
[00:16:09] <ssi> yeah
[00:16:13] <zeeshan> thats not too bad..
[00:16:18] <ssi> well I guess it could be whatever you want
[00:16:28] <ssi> basically tts gives you a flat-nose r8 collet that's 3/4"
[00:16:35] <ssi> and then the holders have a 3/4" shank and a locating shoulder
[00:16:39] <ssi> so the holders could be whatever
[00:16:46] <ssi> I actually turned some holders on my little lathe awhile back
[00:16:58] <zeeshan> say im using a fly cutter
[00:16:59] <zeeshan> with tts
[00:17:03] <anarchos_> i saw a youtube video of someone making some tts holders
[00:17:08] <zeeshan> it'd have to be a straight shank?
[00:17:09] <anarchos_> looked pretty straight forward
[00:17:12] <zeeshan> (kinda scary no?)
[00:17:27] <ssi> all my flycutters are straight shank
[00:17:46] <zeeshan> mine go directly into the r8 spindle
[00:17:52] <zeeshan> i was afraid of them flying out
[00:17:53] <ssi> yea I don't have any that are r8 shank
[00:17:55] <zeeshan> get it? fly cutter!
[00:17:56] <zeeshan> :P
[00:17:58] <ssi> heh
[00:18:40] <zeeshan> let me get this straight
[00:18:44] <zeeshan> so its r8 to 3/4"
[00:18:55] <zeeshan> then all your tools get mounted into a TTS w/ a 3/4" shank
[00:19:20] <zeeshan> how does your tool fall out?
[00:19:27] <zeeshan> when you loosen up the drawbar
[00:19:37] <zeeshan> i usually need to hammer the drawbar bolt
[00:19:41] <zeeshan> to let some of my end mills come out
[00:19:43] <zeeshan> they dont just fall out
[00:20:42] <ssi> drawbar springs
[00:20:50] <ssi> bellevilles
[00:20:53] <zeeshan> ah
[00:21:07] <ssi> then you have either a manual lever to pull the bar down, or an air powered toolchanger
[00:21:24] <zeeshan> i should use one of these voice coil linear actuators
[00:21:27] <zeeshan> that you guys have been posting :p
[00:21:32] <zeeshan> too bad they wont have the force
[00:21:33] <ssi> for that?
[00:21:33] <zeeshan> :p
[00:21:37] <ssi> I don't think they have NEARLY enough force
[00:21:41] <zeeshan> hah, im just kidding
[00:21:42] <zeeshan> i know!
[00:21:42] <ssi> need like 900lb of force or something like that
[00:21:42] <ssi> heh
[00:21:45] <zeeshan> yea
[00:22:00] <zeeshan> i'd need 50 of them in series
[00:22:03] <zeeshan> er
[00:22:04] <zeeshan> parallel
[00:22:14] <ssi> seems legit
[00:22:16] <zeeshan> actually more
[00:22:16] <zeeshan> haha
[00:22:18] <zeeshan> imagine that.
[00:22:33] <zeeshan> ive used an electrically controlled pneumatic valve
[00:22:39] <zeeshan> so i think it's doable..
[00:22:50] <zeeshan> so about 1200$ to cnc the machine with ball screws
[00:22:54] <zeeshan> and prolly another 1000
[00:22:59] <zeeshan> for tts + holders
[00:23:12] <zeeshan> and like 200 bux for a automatic drawbar
[00:23:28] <zeeshan> still a lot cheaper than buying a broken down cnc for 8k
[00:23:35] <toastyde2th> what the hell are you doing that r8's getting stuck
[00:23:51] <zeeshan> toastyde2th: say i got a 3/4" end mill in the r8 collet
[00:23:55] <ssi> i have to hammer the drawbar to release pretty much all my r8 tools
[00:23:56] <zeeshan> and i loosen the drawbar
[00:24:04] <ssi> they grab that taper pretty solidly
[00:24:05] <zeeshan> i have to tap the drawbar to release the 3/4" end mill
[00:24:13] <toastyde2th> yeah, that's normal, but when you have a power drawbar that goes away
[00:24:17] <ssi> I keep a deadblow by the mill for that very reason
[00:24:37] <ssi> well yeah, that's why I told him he needs a power drawbar :)
[00:24:42] <toastyde2th> oh
[00:24:47] <toastyde2th> now i understand the conversation
[00:24:48] <zeeshan> well shit nigguhs, i dont have power drawbar :{
[00:24:49] <toastyde2th> sorry about that
[00:24:55] <toastyde2th> so keep hitting it
[00:25:07] <toastyde2th> I just whack it with the drawbar tightner thing
[00:25:13] <toastyde2th> as our forefathers did
[00:26:02] <toastyde2th> also i don't understand tormach holders
[00:26:10] <toastyde2th> expensive and proprietary
[00:26:17] <ssi> they're not really proprietary :P
[00:26:20] <zeeshan> thers a couple companies
[00:26:21] <toastyde2th> use er-32 and er-16 like the rest of the planet
[00:26:22] <zeeshan> that copy em
[00:26:33] <ssi> er collets are great, but they don't lend themselves to atc
[00:26:40] <toastyde2th> sure they do
[00:26:44] <zeeshan> toastyde2th: how?
[00:26:55] <toastyde2th> I used a whole rack of er chucks with r8 tapers
[00:27:12] <ssi> and your r8 atc works how?
[00:27:21] <zeeshan> http://www.chronos.ltd.uk/acatalog/R8ERL.jpg
[00:27:26] <zeeshan> how do you open that nut
[00:27:27] <toastyde2th> oh, you mean a full-on atc
[00:27:28] <zeeshan> with atc?
[00:27:32] <toastyde2th> you don't open the nut
[00:27:38] <toastyde2th> you drop the whole thing out
[00:27:42] <zeeshan> o
[00:27:43] <toastyde2th> like every machine on planet earth
[00:27:43] <ssi> yeah, the "A" in ATC stands for "not me"
[00:27:53] <toastyde2th> it's just that r8 toolchangers are more of a pain in the ass
[00:28:03] <zeeshan> toastyde2th: i never understood why
[00:28:03] <ssi> http://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=33266
[00:28:10] <toastyde2th> which is why most bridgeports that have auto toolchangers use cat-30
[00:28:11] <ssi> now you have an ER chuck that can (gasp) work with an ATC :)
[00:28:23] <toastyde2th> no, you don't
[00:28:25] <ssi> yeah cat30 would be awesome, but if you have an r8 machine that doesn't help
[00:28:31] <toastyde2th> you have a tormach toolholder with an er chuck on it
[00:28:39] <ssi> that's what I said
[00:28:42] <zeeshan> toastyde2th: source me a cat30 spindle
[00:28:46] <toastyde2th> just like i have an r8 toolholder with an er chuck on it
[00:28:47] <toastyde2th> ebay
[00:28:48] <zeeshan> ever change a spindle before?
[00:28:53] <toastyde2th> the whole head comes off
[00:28:54] <zeeshan> is it hard?
[00:28:54] <zeeshan> :p
[00:28:57] <toastyde2th> it's easy
[00:29:00] <toastyde2th> because you buy the whole head
[00:29:04] <toastyde2th> for like 300 bucks
[00:29:05] <ssi> how much do they sell for?
[00:29:06] <ssi> hm
[00:29:14] <zeeshan> man
[00:29:18] <zeeshan> ultimately cat30 would be the bomb.
[00:29:24] <zeeshan> lots of money saved
[00:29:36] <ssi> http://www.ebay.com/itm/Bridgeport-ProtoTRAK-NT30-Mill-E-mill-Head-Replacement-/170802569615?pt=LH_DefaultDomain_0&hash=item27c4a0618f
[00:29:40] <ssi> or $3500
[00:29:41] <ssi> same thing, right?
[00:29:41] <toastyde2th> prices on bp head fluctuate wildly
[00:29:57] <ssi> haha and that one's R8
[00:30:03] <toastyde2th> yeah that's an r8 head
[00:30:09] <toastyde2th> buy a used one, not a new one
[00:30:16] <ssi> don't see any
[00:30:34] <toastyde2th> you'll probably have to look other places than ebay
[00:30:38] <toastyde2th> however your local machinery market is
[00:31:02] <ssi> http://www.ebay.com/itm/CINCINNATI-MILACRON-VMC-5VC-750-MACHINING-CENTER-SPINDLE-ASSEMBLY-/390200081407?pt=BI_Heavy_Equipment_Parts&hash=item5ad9bcbbff
[00:31:03] <zeeshan> toastyde2th:
[00:31:05] <ssi> there you go zeesh
[00:31:06] <zeeshan> thats a great idea.
[00:31:15] <zeeshan> ssi lol
[00:31:22] <zeeshan> retrofit a cinci head onto the bridgeport?
[00:31:23] <zeeshan> i like this idea.
[00:31:25] <ssi> WHY NOT
[00:31:26] <ssi> :D
[00:31:27] <zeeshan> hahaha
[00:31:29] <toastyde2th> that's most of the weight of a bp
[00:31:33] <ssi> what could go wrong
[00:31:45] <zeeshan> toastyde2th: i was trying to find spindles only, and had a hard time
[00:31:51] <zeeshan> but i bet a whole head would be easier to find
[00:31:51] <toastyde2th> yeah fuck that
[00:31:57] <toastyde2th> redoing a spindle means you have to get new bearings and shit
[00:31:58] <zeeshan> cause it's easier to take off a machine
[00:32:28] <toastyde2th> and then regrind the taper
[00:32:35] <toastyde2th> ain't nobody got time for that
[00:32:39] <ssi> agreed
[00:32:41] <zeeshan> yea
[00:32:42] <zeeshan> fak that
[00:32:57] <zeeshan> is there a disassembly manual for a bridgeport anywhere
[00:33:04] <toastyde2th> there probably is
[00:33:04] <zeeshan> i can only find the operation manual
[00:33:09] <ssi> http://www.ebay.com/itm/Bridgeport-412-X-VMC-CNC-Machine-TNC-2500B-Control/281392583376?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D24641%26meid%3D8556558779949438192%26pid%3D100005%26prg%3D10413%26rk%3D4%26rkt%3D6%26sd%3D291186861436&rt=nc
[00:33:14] <toastyde2th> you'll need a shop crane
[00:33:14] <ssi> that'd be a decent size machine for me
[00:33:20] <toastyde2th> from like harbor freight
[00:33:25] <zeeshan> toastyde2th: i build cars
[00:33:30] <ssi> zeeshan: it's liek four bolts in the front
[00:33:32] <ssi> the head is easy
[00:33:35] <toastyde2th> any time i've disassembled a bp i just take pictures and keep the bolts in ice cube trays
[00:33:38] <ssi> it's the same bolts that adjust the tilt
[00:33:38] <toastyde2th> so i know how shit goes back
[00:33:49] <zeeshan> oh
[00:33:54] <zeeshan> those big 4
[00:34:00] <toastyde2th> i've never had to take the head off, though
[00:34:02] <zeeshan> wtf
[00:34:06] <zeeshan> thats all thats holding the head in
[00:34:08] <zeeshan> i dont believe you!
[00:34:15] <toastyde2th> there isn't much to a bp, quite honestly
[00:34:16] <ssi> well I think it's on a big circular boss
[00:34:18] <ssi> that holds the weight
[00:34:19] <toastyde2th> the most complicated part is in the knee
[00:34:22] <ssi> the bolts just keep it tight on the boss
[00:34:24] <zeeshan> im gonna go check it out
[00:34:40] <toastyde2th> which is the leadscrew frame thing
[00:34:48] <toastyde2th> for the x/y
[00:35:19] <ssi> I wonder how that bridgeport 412X is
[00:35:32] <ssi> I bet I could strip enough stuff off it to lift it with my forklift
[00:35:34] <ssi> says it's 6klb
[00:36:06] <toastyde2th> i strongly recommend against taking apart a vmc or turning center
[00:36:17] <ssi> I mean like taking the control off
[00:36:20] <zeeshan> yep
[00:36:24] <zeeshan> looks like only 4 bolts in the front
[00:36:24] <ssi> with the CRT monitor and everything :P
[00:36:33] <toastyde2th> yeah but that takes you down to 5500 lbs
[00:36:49] <ssi> only gotta shed another 500lb and I'll be golden :)
[00:36:56] <zeeshan> hah
[00:37:03] <toastyde2th> lol
[00:37:05] <zeeshan> you dont need a forklift mate
[00:37:10] <zeeshan> just do it egyptian style
[00:37:12] <ssi> oh cram it with what I need
[00:37:19] <ssi> that's how I moved the bridgeport
[00:37:20] <toastyde2th> also i'd get an old maatsura, mori seiki, etc
[00:37:24] <toastyde2th> rather than a bp vmc
[00:37:31] <zeeshan> toastyde2th: i saw a mori seiki
[00:37:36] <zeeshan> 1982?
[00:37:40] <zeeshan> 20k. wtf?
[00:37:46] <toastyde2th> they're beasts
[00:37:51] <ssi> toastyde2th: if you see anything like that let me know
[00:38:01] <ssi> if I can find a deal on a vmc with an ancient junk control I'll buy it
[00:38:02] <toastyde2th> also larger machines tend to hold their value
[00:38:05] <zeeshan> remember, for me its strictly hobby shop
[00:38:07] <ssi> I want something small tho
[00:38:11] <zeeshan> very small productio nruns
[00:38:12] <ssi> something I can fit in my garage
[00:38:17] <ssi> and avoid paying a rigger
[00:38:21] <toastyde2th> and honestly i wouldn't remove the control on an old mori seiki
[00:38:28] <toastyde2th> the old Fanucs and Yasnacs are really nice to operate
[00:38:41] <ssi> machines with good controls tend to be much more money
[00:38:52] <ssi> that's why the HNC is such a great machine for linuxcnc people
[00:38:56] <ssi> it's solid iron with a CRAP control
[00:39:00] <ssi> so you can buy them for $1k
[00:39:02] <zeeshan> ssi
[00:39:03] <zeeshan> http://www.youtube.com/watch?v=JYwFsY_vZvI
[00:39:04] <zeeshan> :D
[00:39:17] <zeeshan> you were right
[00:39:19] <zeeshan> 4 bolts
[00:39:22] <ssi> sometimes I am
[00:39:23] <zeeshan> slides right out
[00:39:36] <zeeshan> guy lifted it with his hands
[00:39:36] <zeeshan> lol
[00:39:45] <ssi> using the table to pull it is genius
[00:39:50] <ssi> I wouldn't have thought of that :(
[00:39:51] <toastyde2th> i have seen a strange number of good but old machines in the 6k ballpark with working controls
[00:39:55] <toastyde2th> another good brand is OKK
[00:40:05] <toastyde2th> also, don't be afraid of a horizontal mill for a hobby shop
[00:40:08] <ssi> what part of the world are you in?
[00:40:14] <toastyde2th> east coast usa
[00:40:19] <ssi> east coast is a long coast :)
[00:40:26] <toastyde2th> northeast
[00:40:28] <toastyde2th> ish
[00:40:28] <ssi> ah ok
[00:40:29] <zeeshan> http://www.youtube.com/watch?v=HFE_nXQCH6E
[00:40:30] <ssi> I'm in atlanta
[00:40:31] <zeeshan> this guy is even more boss
[00:40:32] <zeeshan> lol
[00:40:49] <zeeshan> toastyde2th: i much rather have a vertical and horizontal mill
[00:40:49] <ssi> ahaha awesome
[00:40:50] <zeeshan> converted
[00:40:52] <zeeshan> than vmc!!
[00:41:07] <toastyde2th> i'd rather have a hmc
[00:41:37] <zeeshan> rofl
[00:41:40] <zeeshan> this guy is awesome
[00:41:47] <zeeshan> just rotates the whole head with 1 finger
[00:42:44] <toastyde2th> i used to run a 20x20 HMC from like, the late 70s
[00:42:53] <ssi> i'd be fine with hmc
[00:42:54] <toastyde2th> it was a very cool machine
[00:42:59] <toastyde2th> no guards, though
[00:43:06] <ssi> I'm not a big fan of safety :)
[00:43:10] <toastyde2th> it was essentially a late-model manual mill with a control on it
[00:43:17] <toastyde2th> huuuuge ways for a tiny-ish machine
[00:43:22] <toastyde2th> although it was probably 15k lbs
[00:43:25] <toastyde2th> didn't have a big footprint
[00:44:23] <toastyde2th> the ways were 6" wide
[00:44:26] <toastyde2th> two per axis
[00:45:36] <zeeshan> find me a cat30/cat40 bridgeport head PLZ!
[00:45:36] <zeeshan> :{
[00:47:19] <toastyde2th> sorry, i'm not in the industry anymore =(
[00:48:33] <ssi> haha
[00:48:39] <ssi> tease
[00:59:19] <ssi> k gotta redesign the mirror mount mount to move it out about a half inch
[01:06:38] <ssi> god it gets late fast
[02:06:41] <Deejay> moin
[03:05:00] <RyanS> LOL
http://www.ultimatetools.com.au/petrol-hammer-drill/#
[03:06:53] <ssi> lol
[03:07:35] <RyanS> Is that just a little silly?
[03:09:50] <Loetmichel> a bit heavy
[04:54:22] <archivist_herron> fscks bricks
[06:02:08] <jthornton> pcw_home, is the DB25F-IDC26 the correct cable to connect to the second port on the 5i25?
[08:02:41] <jthornton> archivist, almost forgot to fix the G01 error...
[09:10:34] <pcw_home> jthornton: yes, thats the correct cable
[09:10:36] <pcw_home> (its a cable and bracket, but you can toss the bracket if you mount the DB25 yourself)
[10:30:36] <PetefromTn_> Well finally got my new Bronco titled and registered. I'm LEGAL now LOL..
[10:32:05] <Tom_itx> BRONCO!
[10:32:17] <Tom_itx> those are ancient aren't they?
[10:33:21] <PetefromTn_> YUP
[10:33:30] <PetefromTn_> They don't make em like this anymore ;)
[10:33:31] <Tom_itx> most are rusted out
[10:33:39] <PetefromTn_> sure as hell are..
[10:33:52] <cradek> tailgate and above the back wheels
[10:33:56] <PetefromTn_> Mine has some rust I will need to remedy but it is a damn clean one.
[10:34:02] <PetefromTn_> yes exactly.
[10:34:11] <Tom_itx> take it to gasmonkey garage
[10:34:13] <cradek> by now their third tailgates are rusted out :-)
[10:34:15] <Tom_itx> they'll fix you right up
[10:34:35] <PetefromTn_> third tailgates?
[10:34:48] <PetefromTn_> Gas monkey LOL. Those guys are crackups.
[10:35:26] <PetefromTn_> I left the courthouse after getting the new tag this morning and it was so nice I put down all the windows including the rear window and drove around a bit.
[10:35:27] <Tom_itx> they are but they seem to know their shit
[10:36:20] <PetefromTn_> I am sure I will have to cut and weld on this thing at some point but thats okay I love these things.
[10:36:35] <PetefromTn_> The last one I had we owned for like ten years.
[10:36:40] <PetefromTn_> Drove the berries off that thing.
[10:37:02] <PetefromTn_> Crossed the country half dozen times wheeled it, camped in it, pulled boats with it. You name it.
[10:37:08] <PetefromTn_> Just a great fun vehicle.
[10:37:19] <PetefromTn_> Love popping the roof off and driving around in it.
[10:40:29] <cradek> I've had an 85 and a 96 and never had the roof off either one
[10:40:41] <cradek> I don't remember if the 85 even came off...?
[10:42:53] <PetefromTn_> You're kidding...
[10:43:00] <PetefromTn_> Thats the best part about owning a bronco LOL
[10:43:18] <PetefromTn_> the tops came off all the fullsize broncos as well as the older ones too...
[10:44:27] <cradek> and driving with the back window seemed to make all the exhaust come in...
[10:44:32] <PetefromTn_> You do have to remove the interior trim around the base of the top. I took mine off and left it in the attic so it does not get jacked up.
[10:44:44] <PetefromTn_> did you have custom exhaust?
[10:45:23] <PetefromTn_> I had put dual exhaust on one of them and yeah it kinda made the exhaust come in but this one has it out the right rear side and it does not seem to come in.
[10:45:57] <skunkworks__> I think that is true with most vehicles.. We drove home with the jetta trunk open - seemed to suck the exaust into the cab
[10:47:14] <PetefromTn_> My suzuki Samurai rock crawlers I have built were good about it. I never had the roof on mine hardly ever. However one time I put a custom exhaust on one of them and made it stick out the back a tad further and it choked me out LOL.
[10:47:38] <PetefromTn_> Took it back and had them trim it to the stock length and it went away. Go figure.
[10:49:42] <PetefromTn_> I remember when I first moved to Tennessee I took my 89 four wheeling with some guys in Suzuki Samurai's with my wife. We nearly slid off the side of a mountain and scared the crap out of us. It is quite a bit wider than the samurai's so when we went on this one trail the edge got a LOT closer for our truck than thiers and we started sliding.... I told my wife to jump out and I was getting ready to bail out the drivers side
[10:50:27] <PetefromTn_> The big Bronco did really good actually other than that on some tough trails. This was in cumberland Gap area. It was not even lifted and had 33" mud tires on it.
[10:50:51] <PetefromTn_> I plan to lift this one up and put 35" mudders on it and do some light wheeling and mall crawling LOL.
[10:52:20] <PetefromTn_> is your jetta a turbo diesel?
[10:53:13] <skunkworks__> it was..
[10:53:21] <skunkworks__> (we sold it a few years ago)
[10:53:26] <PetefromTn_> nice.. Does it get like a BILLION MPGs"
[10:53:27] <skunkworks__> love it.. miss it..
[10:53:50] <skunkworks__> depending on driving - 40 -50mpg
[10:53:52] <cradek> I wish my gti was the diesel. I'd really like the better mileage.
[10:53:56] <PetefromTn_> I know the new ones are some of the most fuel efficient cars on the road apparently including hybrids.
[10:54:07] <PetefromTn_> what year is your GTI?
[10:54:10] <cradek> 03
[10:54:21] <PetefromTn_> nice I love the looks of those... color?
[10:54:24] <cradek> red
[10:54:37] <skunkworks__> my wife and I point them out.. awww - there is a tdi....
[10:54:38] <cradek> yeah it's great. the newer ones are worse so I hope it lasts forever.
[10:54:38] <PetefromTn_> Jeremy Clarkson has a special place in his heart for that one..
[10:55:07] <PetefromTn_> would be nice to get 40-50 MPG tho..
[10:55:25] <PetefromTn_> I think my Bronco gets a couple feet per gallon LOL...
[10:55:36] <skunkworks__> our toyota does pretty good... on long trips it gets 40mpg
[10:55:49] <PetefromTn_> Please tell me it is NOT a prius...
[10:55:57] <cradek> no, prius gets 50
[10:56:01] <skunkworks__> no base corrola
[10:56:09] <PetefromTn_> sweet.
[10:56:26] <PetefromTn_> Ya know what car I really love tho..
[10:56:30] <jdh> my yukon gets 35MP2G
[10:56:36] <PetefromTn_> The ORIGINAL rabbit GTI
[10:56:44] <PetefromTn_> BS
[10:56:45] <PetefromTn_> LOL
[10:57:21] <ssi> skunkworks__: my best tank average in my tdi is 56.9 :)
[10:57:28] <PetefromTn_> I had a friend who had an all black original Rabbit GTI and it was lowered a bit on some nice wide custom wheels and smoked out windows with a bangin alpine stereo back in the day.
[10:57:33] <PetefromTn_> damn that was a fun car to drive.
[10:57:44] <PetefromTn_> Had a power sunroof and the little funky antenna.
[10:57:56] <skunkworks__> ssi, nice!
[10:57:59] <PetefromTn_> why can't they make cars like that anymore..
[10:58:13] <ssi> skunkworks__: it took doing 57mph on the interstate on a road trip with no AC
[10:58:19] <ssi> skunkworks__: but it had to happen to prove a point :)
[10:58:44] <ssi> skunkworks__: my mom lives in Ocala, FL, and it's altmost exactly 400 miles door to door; I left my house, drove to her house, turned around and came back, without fueling
[10:58:45] <PetefromTn_> they are nice cars too..
[10:58:49] <ssi> 814 miles on 14.2 gal
[10:59:03] <PetefromTn_> damn that is amazing..
[10:59:13] <PetefromTn_> what year is that one.
[10:59:15] <ssi> 14
[10:59:22] <PetefromTn_> nice.
[10:59:29] <PetefromTn_> how much did you pay for that thing?
[10:59:34] <ssi> $19,3
[10:59:40] <PetefromTn_> Ouchie.
[10:59:49] <ssi> heh msrp is $24,7
[11:00:04] <PetefromTn_> I would look for a slightly used one I think.
[11:01:06] <ssi> give it a shot
[11:01:10] <PetefromTn_> I have a friend who wheels suzuki samurai's with me that has a VW turbo diesel in his samurai. It has 33" mudders on it, the aerodynamics of a brick wall and gets like 40 MPG LOL...
[11:01:14] <ssi> it's cheaper to buy them new!
[11:01:22] <ssi> everyone wants diesels now
[11:01:27] <PetefromTn_> how ya figure?
[11:02:25] <PetefromTn_> I want to buff and polish the bronco now that I gave it a good bath but it is hot as hell outside right now.
[11:02:32] <ssi> http://www.autotrader.com/cars-for-sale/Used+Cars/Volkswagen/Jetta/Kennesaw+GA-30144?endYear=2014&listingType=used&listingTypes=used&makeCode1=VOLKS&mmt=%5BVOLKS%5BJET%5BJET%7CTDI%5D%5D%5B%5D%5D&modelCode1=JET&searchRadius=25&showcaseListingId=372792034&showcaseOwnerId=5006840&startYear=1981&trim1=JET%7CTDI&Log=0
[11:02:41] <PetefromTn_> I might take the kids to the park today and try to find a nice shdy tree
[11:02:54] <ssi> 2011 TDI with 60k miles, $19,918
[11:03:11] <ssi> 2010 with 73k, $15,989
[11:03:20] <ssi> personally, I'll spend a little bit more to get a brand new car
[11:03:27] <cradek> jeez cars are expensive
[11:03:37] <PetefromTn_> Oh hell no you can't buy one from a STEALERSHIP man...
[11:03:49] <ssi> ok... let me know how it goes :)
[11:04:04] <PetefromTn_> No I won't be buying one...
[11:04:23] <ssi> I agree, because the used market for them isn't cheap enough :)
[11:04:48] <PetefromTn_> no I won't be buyin one because I would not pay anywhere near that much for one.
[11:05:20] <PetefromTn_> They see you coming apparently LOL.
[11:05:50] <ssi> I look at it like this
[11:05:56] <ssi> I drive 25kmi/yr minimum
[11:06:02] <ssi> I was driving a car that got 22mpg
[11:06:07] <ssi> so that's like $10k/yr in fuel
[11:06:20] <ssi> now I drive a car that gets 50mpg
[11:06:24] <ssi> so that's like $2k/yr in fuel
[11:06:24] <ssi> heh
[11:06:36] <ssi> car pays for itself in two and a half years
[11:06:57] <PetefromTn_> Oh you don't have to sell me on the fuel economy man..
[11:07:08] <PetefromTn_> That is the ONLY reason I would ever buy one of those cars.
[11:08:19] <PetefromTn_> but my days of paying $20k for a vehicle are long gone man..
[11:08:28] <PetefromTn_> It is just not worth it to me.
[11:08:37] <ssi> my days of paying $3k for a vehicle and working on it all the time are long gone
[11:08:47] <ssi> I have enough damn projects in my life, i don't need my daily driver to be one
[11:08:56] <PetefromTn_> then you are buying the wrong kind of cars man..
[11:09:20] <ssi> no, I'm buying the right kind of cars! brand new, reliable, nice, fuel efficients :)
[11:09:30] <PetefromTn_> just because you buy a new car does not guarantee it will not need work either.
[11:09:36] <cradek> nah, you're just driving too much, and should move
[11:09:42] <ssi> cradek: yeah, I agree :(
[11:10:05] <ssi> unfortunately the whole "30 tons of machine tools in the basement" thing gets in the way of that :(
[11:10:14] <PetefromTn_> IMO car prices are out of freakin control man...
[11:10:39] <ssi> no they're not... they're just a more true indication of our debilitating inflation
[11:11:08] <PetefromTn_> I would MUCH rather have to pay for an occasional repair which I did even when I had brand new cars and have ZERO car payments than paying $3-400 car payments plus insurance etc. etc.
[11:11:32] <jdh> heh... $300 car payment isn't much of a car now.
[11:11:39] <ssi> jdh: my car payment is $300 :P
[11:11:41] <PetefromTn_> exactly...
[11:11:53] <PetefromTn_> I could put a whole brand new engine in my car for three months car payment..
[11:11:53] <jdh> exactly
[11:11:54] <ssi> that's the funny thing... pete's all riled up about it
[11:12:11] <PetefromTn_> riled up about what?
[11:12:20] <ssi> but I got rid of my $33k, $530/mo 22mpg car in favor of a $19k, $300/mo, 50mpg car
[11:12:27] <ssi> in my eyes the car is practically FREE
[11:12:28] <jdh> if I bought another car, it would be another Yukon XL
[11:12:38] <PetefromTn_> Yukons are nice cars.
[11:12:41] <cradek> hahah XL
[11:12:52] <cradek> that's so funny
[11:12:53] <PetefromTn_> I drove an XL awhile back and it actually hauled ass..
[11:13:01] <jdh> how so? The non-XL is tiny
[11:13:11] <PetefromTn_> I was quite surprised at how quick it was.
[11:13:27] <PetefromTn_> It is also beautiful inside with leather and nice seats etc.
[11:13:31] <jdh> yep
[11:13:45] <jdh> and can tow my boat when needed, and haul all my gear.
[11:13:45] <PetefromTn_> I ALMOST bought a couple year old used one at a dealership about three months ago.
[11:13:51] <PetefromTn_> yeah.
[11:13:59] <PetefromTn_> that is why I bought the bronco.
[11:14:07] <jdh> mine have all been two years old when I buy them.
[11:14:17] <PetefromTn_> Easily towed my boats or whatever and can still put some plywood in it when I need to.
[11:14:26] <PetefromTn_> plus you can pop the roof off LOL
[11:14:31] <PetefromTn_> that is smart.
[11:14:40] <PetefromTn_> You get KILLED on a new car purchase anymore.
[11:15:00] <ssi> I put a trailer hitch on the tdi
[11:15:10] <jdh> geez.
[11:15:15] <ssi> I can tow 2klb with it as per ratings :)
[11:15:16] <ssi> haha
[11:15:30] <PetefromTn_> 2kg
[11:15:39] <jdh> I'm almost unhappy that two of my pressure transducers read 8psi different at 3100ish psi
[11:15:52] <ssi> jdh: what's this on?
[11:16:00] <PetefromTn_> dive stuff I presume
[11:16:03] <ssi> oh right
[11:16:11] <jdh> my compressor:
http://jdh.no-ip.biz:8081/
[11:16:15] <ssi> PetefromTn_: you're just mad cause my 2 liter 50mpg diesel has more torque than your bronco ;)
[11:16:27] <PetefromTn_> GOOD LUCK with that man..
[11:16:48] <PetefromTn_> I would tear your car backwards down the street if we hooked them together LOL...
[11:17:08] <ssi> might be an appropriate time to show you this
[11:17:08] <ssi> https://www.youtube.com/watch?v=0UFVI_MQPEQ
[11:17:11] <ssi> before you get too cocky :)
[11:17:20] <PetefromTn_> then just to piss you off I would then drive over top of your car...
[11:17:28] <jdh> ebay transducers, hacked up ADC board, raspberry pi... 8psi only 0.2%
[11:17:49] <ssi> jdh: I want to put together a little differential pressure monitor to show me the drop across my AC filter
[11:18:06] <jdh> ssi: I got some that would do that as samples.
[11:18:29] <PetefromTn_> what kinda BS video is that..
[11:18:40] <ssi> jdh: freescale?
[11:18:45] <ssi> I used to get samples from them all the time
[11:18:46] <jdh> yeah, MPX
[11:18:51] <PetefromTn_> If that truck would not drag that Toareg down the street I would take it out back and shoot it..
[11:18:53] <ssi> about ten years ago I designed a little digital boost gauge
[11:19:10] <ssi> PetefromTn_: best go get your gun ready
[11:19:25] <jdh> got some differentials but I don't remember why. I have an absolute one in my o2 sensor checker
[11:20:05] <ssi> I also have this desire to make a modular pressure logging system, wireless
[11:20:12] <PetefromTn_> I will drive my Bronco down there and bring a strap and when I am done destroying your VW we can listen to your stereo....LOL
[11:20:12] <ssi> for airplane testing
[11:20:28] <jdh> my sensor checker does pressure + 3 o2 sensors over bluetooth
[11:20:33] <ssi> put them in the upper/lower cowl to measure cooling drops, put them out at various places on the airframe to measure turbulence, etc
[11:20:38] <ssi> nice
[11:21:16] <jdh> we use magnehelics for filter monitoring at work.
[11:21:40] <ssi> PetefromTn_: what engine? 5.0?
[11:21:53] <PetefromTn_> 5.8 351
[11:22:58] <PetefromTn_> Besides do you have a v10 diesel toareg?
[11:23:08] <ssi> lucky for you, no :)
[11:23:13] <ssi> the v10s are 660lbft torque stock
[11:23:29] <PetefromTn_> so?
[11:23:46] <PetefromTn_> Its all about weight and gearing man..
[11:24:07] <ssi> yeah tell that to the guy in the chevy :)
[11:24:09] <PetefromTn_> I need to pull this monster in the shop and buff it out but it is so damn hot today..
[11:24:25] <PetefromTn_> that was a BS video man.. or there was something seriously wrong with that truck LOL.
[11:24:30] <Tom_itx> 103F today here
[11:24:34] <ssi> there was something wrong with it
[11:24:35] <ssi> it's RWD
[11:24:39] <Tom_itx> and probably 70% RH
[11:24:51] <PetefromTn_> looked 4x4 to me man..
[11:24:58] <ssi> watch it again
[11:25:00] <ssi> and watch the wheels
[11:25:03] <PetefromTn_> no thanks.
[11:25:10] <PetefromTn_> This is all bs anywyas.
[11:25:10] <ssi> truth hurts, I know :)
[11:25:19] <PetefromTn_> OK
[11:25:25] <PetefromTn_> you're right and I am wrong.
[11:25:38] <PetefromTn_> feel better now.
[11:25:44] <ssi> haha
[11:25:50] * Tom_itx waits for the testosterone to settle
[11:26:07] <ssi> Tom_itx: it's more of a colloid suspension
[11:37:08] <ssi> two mirrors aligned!
[11:37:11] <ssi> one more to go!
[11:38:48] <zeeshan> ^ nice
[11:38:49] <zeeshan> :)
[11:39:18] <jfigie> can I run a saved hal file after I have started hal from halcmd: prompt? I know I can run a saved file with halrun -I -f <filename>
[11:39:49] <zeeshan> ps
[11:39:54] <zeeshan> i have more torque in my rx7
[11:39:57] <zeeshan> than both of your trucks combinewd
[11:39:58] <zeeshan> :-)
[11:41:24] <PetefromTn_> shoulda left it a rotary..
[11:41:33] <archivist> my truck is just bigger :)
[11:42:39] <zeeshan> why would i leave it rotary
[11:42:41] <zeeshan> rotary is garbage
[11:43:18] <zeeshan> i had that nonsense for like 5 years
[11:43:25] <zeeshan> before i went to a better platform
[11:44:14] <zeeshan> lq9 6.0L twin turbo is >>>>>>>>>>> rotary with a large rotary
[11:44:34] <zeeshan> i make like 600ft-lb at 2500 rpm
[11:44:42] <zeeshan> its like an electric motor... almost!
[11:45:50] <jthornton> I make like 3,000 ft-lbs at 1500 rpm
[11:45:58] <zeeshan> jthornton: in what? :D
[11:46:22] <jthornton> JD 350
[11:46:30] <zeeshan> haha
[11:46:53] <jthornton> and I can crush your rx7 flat as a pizza box LOL
[11:47:02] <zeeshan> you'd have to catch me first
[11:48:57] <jthornton> that could be a small challenge, maybe push a tree down in front of you
[11:49:11] <zeeshan> hehe
[11:49:20] <ssi> :P
[11:50:33] <zeeshan> im looking forward to a weekend of working onthe car
[11:50:37] <zeeshan> and not machining anything
[11:50:52] <zeeshan> bah actually itake tha tback
[11:50:56] <zeeshan> i need to make some spacers/adapters
[11:51:07] <zeeshan> ssi laser cut me some stuff
[11:51:11] <zeeshan> hurry up and finish
[11:51:12] <Tom_itx> just an excuse to machine
[11:51:19] <Tom_itx> you know you really want to...
[11:51:23] <zeeshan> no
[11:51:28] <zeeshan> im tired of machining all week
[11:51:34] <zeeshan> for school related stuff
[11:51:34] <ssi> zeeshan: almost done building, but I have to figure out gcode and cam :P
[11:51:43] <zeeshan> ssi thats the easy part :P
[11:51:48] <ssi> good, help me
[11:51:55] <Tom_itx> ssi for what?
[11:51:57] <ssi> laser
[11:52:01] <ssi> cutting doesn't seem too bad
[11:52:06] <Tom_itx> sheetcam
[11:52:11] <ssi> but raster engraving... I'm just not sure how that's gonna work
[11:52:12] <zeeshan> ssi, just drop your patterns in inventor or solidworks
[11:52:17] <zeeshan> transfer em over to a cam software
[11:52:24] <zeeshan> and select the lines and generate a tool path :P
[11:52:37] <ssi> I'm not talking about that part
[11:52:41] <Tom_itx> laser gcode seems drop dead simple
[11:52:49] <zeeshan> you're talking about controlling the laser intensity?
[11:52:51] <ssi> yes
[11:52:58] <ssi> what g-code to use for laser power, on/off, etc
[11:53:00] <zeeshan> thats easy too!
[11:53:04] <Tom_itx> adapt spindle speed for that
[11:53:04] <ssi> for ENGRAVING
[11:53:11] <zeeshan> Tom_itx: exactly what i was thinking
[11:53:23] <zeeshan> make the spindle speed propertional to your laser current
[11:53:30] <ssi> yeah so now
[11:53:38] <zeeshan> and then just order a S100 S2000000
[11:53:40] <ssi> how do you change the spindle speed on a raster line?
[11:53:42] <zeeshan> whenever you wanna change the itensity
[11:53:57] <ssi> skunkworks__ suggested last night that I use M67 so it's synchronized
[11:54:06] <zeeshan> wassat
[11:54:08] <zeeshan> raster line
[11:54:09] <Tom_itx> ssi ask jymmmmmmmmmmmmmmmmmmm how he does it
[11:54:09] <ssi> but my concern is that the motion planner is going to try to come to a stop at every point where the intensity changes
[11:54:18] <ssi> jymmmmmmmmmmmmmmmmmmmmmm doesn't do it
[11:54:23] <ssi> he lets the chinese laser onboard computer do it
[11:54:42] <ssi> I dunno what the state of CV mode is in lcnc, or how that'll work
[11:54:44] <Tom_itx> doesn't he have to enter a .ngc?
[11:54:46] <ssi> I have some research and testing to do
[11:54:49] <zeeshan> whats a raster line?!?!
[11:54:54] <Tom_itx> like a printer
[11:55:04] <Tom_itx> raster graphics
[11:55:12] <zeeshan> i'm confused to what the problem is
[11:55:24] <zeeshan> if you just do S200 then G01 x y 2139081303 ,
[11:55:27] <zeeshan> then do S0
[11:55:31] <ssi> zeeshan: if I try to explain it to you, will you refrain from telling me I'm an idiot?
[11:55:39] <zeeshan> wouldn't that work?
[11:55:54] <ssi> I'm trying to find a video to show you
[11:56:00] <zeeshan> ssi, only if you type at 1400 ipm
[11:56:02] <zeeshan> :-)
[11:56:17] <ssi> https://www.youtube.com/watch?v=dvV_E82ztk0
[11:56:17] <zeeshan> i'm a troll at heart
[11:56:20] <ssi> skip in to like 3:30
[11:56:39] <zeeshan> okay so its a line
[11:56:40] <ssi> the head is just scanning the bed like a TV does
[11:56:42] <zeeshan> with varying laser itensity
[11:56:44] <zeeshan> right?
[11:56:49] <ssi> and the intensity varies according to the grayscarle value
[11:56:49] <ssi> right
[11:56:58] <ssi> so... how do you write that in g-code?
[11:56:59] <zeeshan> that just means your g-code will be so dirty
[11:56:59] <zeeshan> lol
[11:57:06] <ssi> well more than that
[11:57:11] <ssi> if it's exact stop,
[11:57:12] <zeeshan> you'd do something
[11:57:17] <ssi> it'll accel, move, decel to EVERY PIXEL
[11:57:20] <ssi> change the intensity, etc
[11:57:22] <zeeshan> exactly
[11:57:30] <ssi> it needs to be constant velocity mode, if that's a thing yet
[11:57:38] <zeeshan> you can do constant velocity m ode
[11:57:39] <ssi> and it needs to synchronize the intensity changes to the position
[11:57:42] <ssi> and I'm not sure how to do that
[11:57:55] <archivist> methinks the solution is already on the wiki
[11:57:57] <mozmck> what about the S code
[11:58:02] <ssi> archivist: I just haven't looked into it yet
[11:58:14] <zeeshan> ssi will you etch a nude lady for me
[11:58:16] <zeeshan> on a piece of stainless
[11:58:24] <ssi> only if you're nice :)
[11:58:27] <zeeshan> :)
[11:58:48] <zeeshan> i think the cheap and dirty solution is doing it pixel by pixel
[11:59:15] <zeeshan> and just doing like S1000, G01 x0.01 y0 , s200, g01 x0.02 y0
[11:59:17] <zeeshan> or something
[11:59:21] <zeeshan> :P
[11:59:33] <zeeshan> 10,000,000 million line g-code
[11:59:35] <zeeshan> to get one image done
[11:59:40] <archivist> nope look on the wiki somewhere
[11:59:44] <ssi> archivist: yeah I will
[12:00:01] <ssi> i'm going to start with vector cutting, but I have to make sure I set the mahcine up so the proper gcode controls the laser now
[12:00:06] <archivist> may have been on the mailing list too
[12:00:07] <ssi> so I don't have to rework it when I get to engraving
[12:00:55] <mozmck> ssi:
http://www.cnczone.com/forums/general-laser-engraving-cutting-machine-discussion/186700-linuxcnc-laser-control-dont-need-dsp.html
[12:01:29] <zeeshan> ssi what what laser do you have
[12:01:34] <zeeshan> *W
[12:04:52] <Tom_itx> are they using Z as the intensity?
[12:05:11] <zeeshan> yea looks like it
[12:05:12] <ssi> zeeshan: cheapest chinese 40W money can buy
[12:05:17] <zeeshan> 40W can cut how much
[12:05:22] <ssi> I dunno yet
[12:05:26] <Tom_itx> your finger
[12:05:35] <ssi> depends on the optics...
[12:05:39] <zeeshan> ah
[12:05:45] <ssi> probably a fair bit. I have a 1.5" lens and a 2" lens
[12:05:54] <zeeshan> so you're focusing the beam
[12:06:02] <ssi> the 2" lens will do 4kw/mm^2 at 2mm dof, and the 1.5" will do 7kw/mm^2 at 1mm dof
[12:06:03] <ReadError> can you get really focused optics?
[12:06:09] <ReadError> like if I wanted to do PCB stencils
[12:06:20] <ReadError> could it do fine pitch pads you think?
[12:06:20] <zeeshan> does the lens heat up?
[12:06:23] <ssi> ReadError: sure
[12:06:24] <zeeshan> (and require cooling)
[12:06:28] <ssi> zeeshan: not on this little guy
[12:06:38] <ssi> big lasers, yes
[12:06:41] <ssi> the mirrors are watercooled
[12:06:46] <ssi> and I imagine the lens is too somehow
[12:06:48] <zeeshan> :D
[12:07:07] <Tom_itx> ssi, you need one of these to focus the lens:
http://tom-itx.ddns01.com:81/~webpage/motors/focusring11.jpg
[12:07:20] <Tom_itx> focus ring taken from some medical equipment
[12:07:24] <ssi> haha neat
[12:07:30] <ssi> nah focus on this is dirt simple
[12:07:32] <Tom_itx> coarse and fine adjust
[12:07:39] <ssi> the focal length is fixed by the lens
[12:07:47] <ssi> the spot height is controlled by moving a tube up and down
[12:07:48] <Tom_itx> 2 motors with encoder feedback
[12:07:58] <ssi> the spot will always be at a fixed distance from the nozzle
[12:08:15] <ssi> so I can just find that distance, andthen always set up by dropping the nozzle on a jo block and tightening it
[12:09:25] <zeeshan> why is it that when you buy 3/4" round bar
[12:09:32] <zeeshan> its always .748?
[12:09:36] <zeeshan> ..
[12:09:51] <zeeshan> they really expect you to buy 1" round bar so you can precision machine something to .75?
[12:09:57] <zeeshan> or am i ordering the wrong type of round bar
[12:10:22] <archivist> rolled/ground/black or what
[12:10:54] <Tom_itx> zeeshan, we cut 1" test specimens from 6" blocks
[12:10:55] <zeeshan> hot roll
[12:11:05] <zeeshan> Tom_itx: why
[12:11:07] <Tom_itx> sometimes bigger than that
[12:11:12] <ssi> zeeshan: precision shafting
[12:11:15] <Tom_itx> for material testing
[12:11:24] <Tom_itx> end grain and side grain
[12:11:28] <Tom_itx> 6 samples each
[12:11:38] <Tom_itx> also did a bunch of flat specimens
[12:12:00] <zeeshan> ah
[12:12:38] <Tom_itx> cut em real precise so they can just break em
[12:12:46] <zeeshan> even cold roll
[12:12:49] <zeeshan> is minus 0.002
[12:12:49] <zeeshan> wtf
[12:12:57] <IchGuckLive> hi all B)
[12:13:07] <ssi> hey ich
[12:13:13] <Tom_itx> there's the German
[12:13:13] <ssi> I'm aligning the laser now
[12:13:31] <IchGuckLive> ;-)
[12:13:31] <ssi> working on the head mirror; got the x and y beams parallel to travel and centered up inthe head
[12:13:49] <IchGuckLive> Tom_itx: someone asked about me ?
[12:14:10] <Tom_itx> not that i'm aware of
[12:14:26] <IchGuckLive> so why there is the german
[12:14:52] <Tom_itx> you arrived
[12:15:08] <IchGuckLive> not many times from now !
[12:15:34] <IchGuckLive> ssi did you male a cut test
[12:15:45] <IchGuckLive> make
[12:18:01] <ssi> not yet
[12:20:08] <ssi> installing the lens now :)
[12:20:47] <Tom_itx> keep your fingerprints off ti
[12:20:49] <Tom_itx> it*
[12:20:58] <ssi> of course
[12:21:10] <Tom_itx> where did you get the lens
[12:21:29] <ssi> china, naturally
[12:24:11] <ssi> damn, it works :D
[12:24:17] <ssi> also, got myself with the beam for the first time, weee
[12:24:27] <ssi> feels like a bee sting
[12:24:28] <ssi> haha
[12:26:27] <ssi> https://pbs.twimg.com/media/BtZ8RRACUAIMQ5M.jpg:large
[12:26:37] <ssi> unevenness of the line is cause I was moving the head by hand
[12:26:43] <ssi> which is how I got myself with the beam :)
[12:27:02] <Tom_itx> ninny
[12:30:58] <Tom_itx> silence after that comment is worrysome
[12:31:15] <ssi> haha
[12:31:16] <ssi> I'm fine
[12:31:38] <ssi> so I gotta get everything hal'd up so I can write a test program
[12:31:58] <ssi> write a program which'll draw lines and pause so I can move the focus up and down
[12:32:04] <ssi> measure the thinnest line and that'll be best focus height
[12:33:09] <Tom_itx> are you moving the mirrors or the table?
[12:33:20] <ssi> the mirrors
[12:33:27] <ssi> for focus?
[12:33:29] <ssi> just the lens
[12:33:37] <Tom_itx> for burning
[12:33:52] <ssi> there's one fixed mirror, one mirror that moves with the gantry, and one in the head
[12:40:16] <Tom_itx> what stepper drivers are you using on that?
[12:40:26] <ssi> leadshine 556
[12:46:33] <ssi> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Rastering_With_A_Laser
[12:46:36] <ssi> good, so I'm not crazy
[12:48:03] <Tom_itx> do pixelated lines make you crazy?
[12:48:20] <ssi> people gaslighting me makes me crazy :)
[12:59:12] * Jymmm smacks the shit out of ssi with the MADE IN USA laser controller with dual uC and FPGA's!
[13:06:14] <Smidge204__> pew pew pew
[13:09:18] <IchGuckLive> you gone make it Smidge204__
[13:13:16] <IchGuckLive> i am fightiong with the wheat harvester data workaround !
[13:14:00] <Smidge204__> Maybe you have a gluten allergy
[13:16:08] <IchGuckLive> ;-) bad logistic on field change bad organiser on transport to farm timings
[13:18:56] <IchGuckLive> sometimes even openofice strikes me out why is only on one page a pagenumber ...
[13:35:09] <IchGuckLive> ok im off BYE
[13:48:00] <ssi> Jymmm: my mistake :P
[13:52:17] <Jymmm> ssi: My laser in on the LAN, I can "print" to it just like a laser printer. It installs as a print driver and serves as the CAM aspects, so I could print from any application if I wanted to.
[13:55:33] <serp> what laser is that Jymmm?
[13:56:17] <ssi> Jymmm: yeah I understand that
[13:56:21] <Jymmm> ssi: As a generality... The primary settings I have a choice of are: Power%, Speed%, PPI, and DPI. These four are the main things, but some alter/combine the PPI/DPI into other variants which I'm not sure of.
[13:56:21] <ssi> that's just not what I want :)
[13:56:40] <ssi> gotcha
[13:56:42] <Jymmm> ssi: I could care less what you want =)
[13:56:59] <Jymmm> I'm telling what is =)
[13:58:43] <Jymmm> Now, the drawbacks of the FPGA standalone onthe lan is that everything has to be changed at the FPGA level, what they are doing now is eliminating the FPGA and going strictly Host based and everything is in the driver, and the laser just being a dumb device.
[14:02:33] <Jymmm> Also, some are still making it a dumb device on the lan, but REQUIRE a active host (pc) while running jobs. You can't just send a job to the laser and turn off the PC.
[14:19:07] <Loetmichel> btw: my finger gash from yesterday is already nearly closed... thank to whoever is responsible to my fast healing abilities->
http://www.cyrom.org/palbum/main.php?g2_itemId=15084 (caution, graphic laceration) :-)
[14:19:28] <ssi> not too bad
[14:19:54] <ssi> I got myself with the beam for the first time today
[14:20:34] <Loetmichel> yesterday you could see the tendon moving
[14:20:39] <ssi> oh wow haha
[14:20:40] <Loetmichel> ... and loads of blood
[14:21:10] <Loetmichel> happens when you use a dremel like tool wiht a cutting disk and "slip" a bit
[14:22:12] <ssi> gah why is everything in the world so expensive
[14:24:48] <kfoltman> ssi: because of the lizard people, of course!
[14:26:08] <ssi> of course!
[14:43:29] <kfoltman> ssi: I'm just playing with a dev board I paid about 7 euro for ;)
[14:43:43] <kfoltman> some small version of stm32f103
[15:32:40] <anarchos_> is it normal that my charge pump pin is outputting only 5 khz?
[15:32:45] <anarchos_> i thought it was suppost to be 12?
[15:33:04] <anarchos_> it works and everything, just playing around with my new (and first) multimeter :)
[16:24:54] <CaptHindsight> pcw_d525 pcw_home what is your guesstimate bandwidth for the THC cards analog input since the RFI filters are 3db @ 2.5KHz and freq counter gate time?
[16:26:56] <CaptHindsight> ah never mind I just saw "12 bits at a 250 Hz sample rate."
[16:30:19] <kfoltman> woohoo the gerber renderer is working :)
[17:00:28] <Deejay> gn8
[18:12:32] <ssi> dang it
[18:12:40] <ssi> I almost but not quite got everything I need to plumb air assist tonight :(
[20:05:26] <andypugh> I am starting to feel like I might actually run out of jobs to do on the Ner-a-Car.
[20:05:43] <andypugh> It suddenly feels rather close.
[20:05:44] <andypugh> https://picasaweb.google.com/108164504656404380542/NerACar
[20:05:57] <ssi_> haha
[20:06:31] <ssi_> looks like quite a project
[20:07:02] <andypugh> Well, yes, it was meant to keep me enterained for years, not months :-)
[20:07:36] <ssi> :D
[20:07:44] <ssi> I wish I had that problem
[20:07:45] <ssi> heheh
[20:07:53] <ssi> "oh no I'm finishing my projects too quickly!"
[20:09:33] <andypugh> Luckily I have plenty.
[20:16:36] <CaptHindsight> andypugh: volunteer to watch some neighbors toddlers or kids, that will slow you down, have them help then you'll see negative progress :p
[20:18:20] <andypugh> Oh, yes, I know. I have two nieces and a nephew. When they are around _everything_ stops happening and everything is _about_ them. It actually bothers me. I don’t get to “see” my sisters, I get to interact with small unfinished people who are less fun than kittens.
[20:21:32] <SpeedEvil> andypugh: Does the car fly yet?
[20:22:26] <andypugh> It could, I think. I could rig up some sort of fuel tank, and there is somewhere to sit that isn’t the back wheel now.
[20:23:01] <andypugh> But there are still no brakes, so that seems unwise.
[20:23:03] <CaptHindsight> andypugh: do you have a pick of the steering? I still can't see exactly how it turns
[20:24:52] <andypugh> CaptHindsight: Does this picture (not mine) help?
http://kickstart.bikeexif.com/wp-content/uploads/2010/11/neracar-3.jpg
[20:26:19] <CaptHindsight> heh pic stalls out half way
[20:27:25] <CaptHindsight> ok loaded

[20:30:35] <ssi> "small unfinished people"
[20:30:36] <ssi> classic
[20:31:30] <XXCoder> CaptHindsight: interesting
[20:31:38] <ssi> trying to make a video of the laser cutting
[20:31:40] <ssi> but my phone died :(
[20:33:23] <XXCoder> aw
[20:33:27] <XXCoder> recharge stat!!!
[20:35:30] <jdh> must be an iphone, it's after 7pm
[20:37:06] <ssi> I have everything in place except enclosure panels and exhaust
[20:37:13] <ssi> and the honeycomb bed
[20:37:18] <ssi> bed is just a piece of mdf at the moment
[20:38:05] <ssi> my plan is to laser cut all the lexan panels for the enclosure :)
[20:38:10] <ssi> meta laser is meta
[20:38:32] <Valen> they do say you shouldn't laser polycarb
[20:38:40] <ssi> I haven't seen anyone say that
[20:39:20] <ssi> I've heard the fumes aren't pleasant, but I haven't heard that it's dangerous
[20:39:25] <ssi> just chlorinated plastics that are dangerous
[20:39:36] <Valen> thats the reason for it
[20:40:12] <XXCoder1> don't laser burn pvc
[20:40:18] <ssi> I'm aware
[20:40:20] <XXCoder1> unless you got big vent going to outside
[20:40:28] <XXCoder1> yeah bit kidding lol
[20:40:45] <ssi> i am intending to do exhaust of some kind
[20:40:54] <ssi> dunno if it's gonna be outside, or some kind of scrubber, or what
[20:41:06] <XXCoder1> Well as envormentist I recommand scubber
[20:41:09] <XXCoder1> but whatever
[20:41:21] <ssi> damn envormentists
[20:41:43] <XXCoder1> so you rolling coal eh lol
[20:41:49] <ssi> well, point me at one and if it's reasonably priced I'll order it
[20:42:02] <andypugh> I am a bit scared now. I think my network might be compromised. If I google “small unfinished people” (with the quotes) I only get two hits, and both go to the same indirection page. I thought it might be some sort of malware on the Mac, but the iPhone is the same, and so is a Ubuntu VM. So, it looks like something horrible on the router or the ISP?
[20:42:26] <ssi> andypugh: I only get two hits as well
[20:42:32] <ssi> I think you are the originator of that phrase, my friend
[20:42:45] <andypugh> And they go somewhere worrying?
[20:42:51] <Valen> adblock is killing the redirect off for me
[20:42:58] <ssi> yea some kind of linkbait crap
[20:43:33] <andypugh> How very strange.
[20:43:44] <XXCoder1> yeh got million results here
[20:44:01] <andypugh> XXCoder1: With the quotes?
[20:44:05] <Valen> with the quotes?
[20:44:14] <XXCoder1> nope 2
[20:44:26] <XXCoder1> lots picture results though
[20:45:14] <andypugh> Images seems to drop the quotes (it says so at the top)
[20:45:17] <ssi> andypugh: I think you're safe... the whole internet is compromised :)
[20:45:29] <XXCoder1> congats andypugh
[20:45:49] <andypugh> Oh my Ged! I need to stop using it, then what will I do?
[20:45:54] <XXCoder1> its hard to come up with 3 words that make sense that's almost "ungoogleable"
[20:46:14] <ssi> http://en.wikipedia.org/wiki/Googlewhack
[20:47:03] <andypugh> Yes, but, it seems _such_ an obvious description of children that it seems there must be something wierd going on.
[20:47:15] <ssi> obvious only to you, my friend
[20:47:20] <ssi> which is why it made me smile when you said it!
[20:51:00] <XXCoder1> theres a book titled unfinished people
[20:51:03] <XXCoder1> closest thing
[20:58:06] <Tom_itx> andypugh, have you done much with wheezy?
[20:58:19] <andypugh> Nothing at all.
[20:58:22] <Tom_itx> trying to figure out autologin

[21:32:36] <ssi> gantry accel shakes the machine a bit, and it's pretty visible in a tiny line
[21:32:42] <XXCoder1> nice artwork
[21:34:23] <andypugh> ssi: You need anti-jerk. We don’t have that. :-(
[21:34:32] <andypugh> You should add it :-)
[21:34:47] <XXCoder1> ssi: do gantry shake or whole thing?
[21:34:53] <XXCoder1> if whole thing maybe more mass for base
[21:34:57] <ssi> whole thing
[21:35:06] <ssi> I need to add the plywood shelf below, that'll add some damping
[21:35:11] <ssi> andypugh: how would anti-jerk work?
[21:35:30] <ssi> limit the rate of change of accel?
[21:35:35] <andypugh> You limit the third differential of position.
[21:35:41] <andypugh> Yes, exactly
[21:35:51] <XXCoder1> https://i.chzbgr.com/maxW500/6513131008/h633DA6B1/
[21:36:01] <ssi> heh I'm game
[21:36:09] <ssi> I dunno if i have the smrts for it, but I can try! :)
[21:36:54] <andypugh> I think that it already exists in the Ariasrobot branch, and Rob Ellenberg has touched on it.
[21:37:18] <andypugh> It basically involves writing a new motion planner, again…
[21:37:24] <ssi> that bad, huh
[21:37:39] <XXCoder1> try more mass first
[21:37:51] <XXCoder1> somehow add heavy weights to base as well as add plywood shelf
[21:38:02] <ssi> well if I add the shelf, then the coolant sump can sit on it
[21:38:05] <ssi> which is 5gal water
[21:38:05] <XXCoder1> rigid weights
[21:38:23] <andypugh> Guy wires to the corners of the room :-)
[21:38:44] <ssi> I think crossbracing will help too
[21:38:55] <ssi> once I get the panels in place, that'll stiffen some of it up
[21:39:00] <ssi> then I can cross-brace the legs
[21:39:03] <ssi> maybe with wires infact :)
[21:39:21] <XXCoder1> yeah. you heard of those rubber balls that doesn't bounce? those rubber would be great anti-vobration too

[21:46:07] <XXCoder1> sorry too much handheld, unwatchable for me
[21:46:23] <ssi> I'll try to get the production crew in here next time
[21:46:49] <XXCoder1> for most people it probably would be fine
[21:46:53] <XXCoder1> not me though :(
[21:46:58] <XXCoder1> my brain sucks
[21:48:15] <Flipp> qq on solidworks: I'm designing a flat, square aluminum bracket; how do I remove "excess" material inside, leaving behind an X of support?
[21:48:26] <andypugh> That’s actually quite cool. No actual dumbing-down, just interesting materials stuff.
[21:48:51] <XXCoder1> glad you like it. autocaption was just gbberish
[21:50:35] <andypugh> Autocaption on my hobbing video on YouTube always has me saying “wrinkled popes” for (IIRC) “spindle encoder”
[21:51:12] <XXCoder1> lol is that yourn little you name ;)
[21:52:42] <andypugh> Sorry, I can read most of the words, but they make no sense.
[21:52:47] <CaptHindsight> Flipp: look for solidworks videos on CUT EXTRUDE
[21:52:47] <andypugh> It must be time for bed.
[21:52:55] <andypugh> Night all
[23:30:42] <XXCoder1> heys
[23:30:46] <XXCoder1> got a shop question
[23:32:13] <XXCoder1> I just built my drill press
[23:32:19] <XXCoder1> but chuck dont fit in :(
[23:46:18] <toastyde1th> don't fit in what
[23:46:23] <XXCoder1> spidle
[23:46:32] <toastyde1th> what on the ass end of the chuck
[23:46:43] <XXCoder1> tried hammering it in using rubber hammer but...
[23:47:37] <ssi> lol
[23:47:43] <toastyde1th> no i mean what's the chuck mounted to - is it a morse taper, straight taper, etc?
[23:48:01] <toastyde1th> or is it just the raw chuck
[23:48:02] <XXCoder1> hold on
[23:49:00] <XXCoder1> well the shaft has gentle slope
[23:49:09] <XXCoder1> the end that goes inside head is smallest
[23:49:20] <toastyde1th> k so it's a morse taper
[23:49:28] <XXCoder1> the other end, one that holds chuck, is bit odd shape
[23:49:44] <XXCoder1> looks like stright shaft but curves outwards?
[23:49:53] <toastyde1th> http://www.victornet.com/images/ArborDiagram.GIF
[23:49:54] <XXCoder1> or does that not matter
[23:49:56] <ssi> like it used to be a straight shaft but you whacked it with a hammer?
[23:50:00] <toastyde1th> does it look like that
[23:50:13] <XXCoder1> morse taper end yes
[23:50:22] <XXCoder1> other end nope
[23:50:25] <toastyde1th> you should take pictures instead
[23:50:29] <toastyde1th> because this is going to be a circus
[23:50:34] <ssi> :)
[23:50:36] <XXCoder1> lemme try remove chuck and take pics
[23:51:16] <ssi> I wish i had thought tobuy some 1/8" acrylic today! :(
[23:54:00] <toastyde1th> aw
[23:54:57] <ssi> I need to find a way to calculate feedrates for laser
