JT: I use DNMG432's in my lathe ...
Dave911: I have a big fist full that a buddy gave me
too big for me
I also have some 1/2" IC E's I think
* JT-Hardinge smells dinner
What do you want for them?
Most of the inserts on my lathe are the 1/2" IC inserts.
Sorry ... I've been running in and out a lot today ....
History Channel NOW if you're near a TV
I can dull just about anything
I'm having sticker shock shopping for motor drives on ebay
is full 4-axis machining limited to the controller? if I replace the existing controller with EMC could it be possible to use the 4th axis (on a horizontal cnc mill that currently only indexes then locks in position) as a moving-while-machining axis? Think turbine, as an example.
on a side note... anyone want to complete a lathe? http://toronto.kijiji.ca/c-buy-and-sell-tools-equipment-Lathe-VDF-800-W0QQAdIdZ191426141
elmo40: if it's mechanically suitable you could do coordinated motion on it
my experience with a locking indexer is that it has huge backlash on purpose, so the lock has freedom to move the table into the exact desired location
emc2 git master has support for locking indexing rotaries, btw
currently, git master can support coordinated+nonlocking, or indexing+locking
(um, for $35k I'd expect to get all the parts)
I know, expensive...
cradek: git has this support? nice.
yes - docs are probably behind - but it's in there
I was worried about that. so much play in the table just for the locker. makes sense, sorta :P
yeah mine's awful, like 1/2 turn of the worm lash
perfect as an indexer, useless as coordinated

looking for investors. with 150k PLUS working and you only make 4k/mo? insane.
I wonder what they want the 150k for.
to hire an editor who can run a spell check?
but this is what I was looking to acquire. http://toronto.kijiji.ca/c-buy-and-sell-tools-equipment-Hitachi-HG-400-W0QQAdIdZ191556259
this one looks rather 'well used'. too expensive. http://qurl.org/C41
looks like a useful machine - nice size
people really need to learn how to make an advert: http://qurl.org/D41
nice size but too expensive.
I would only offer $12k
$28 to 32 per hour - Annual income in the + $80,000 range.
this looks interesting. http://qurl.org/E41
that seems like a lot of hours per week...
48-55 hours a week

\o/ added logging to znc finally, no more missing what is said as morficmobile
but more importantly I wonder why my irc keeps getting reset???
did you check you're dsl or cable modem connection ?
I replaced mine at home a few days ago because the link went up/down all the bloody time
I have a radio antenna connection to a tower up the hill
if you are connected through an ethernet cable just try mtr 220.127.116.11
and let it run for a few hours
in a terminal window?
yes in a terminal windows under your favourite brand of linux
if you are connected through an antenna then ping or mtr the other side of the antenna link
that way you'll see the quality of the connection quite nicely
how do I mtr the other side?
you'll see the hops
the first one is probably your router (local ip : 192.168.x.1 probably)
the next one is at your provider
so you can ping/mtr that one
for wireless links (like your dish) it's best to use a larger packet size for ping
ping -s iirc (but the manpage knows more)
ok I see that now
jthornton: try an irc client instead of chatzilla in a browser?
well it seems that I'm on irssi
wifi is radio by the way
john___ is now known as jthornton
my VMC should be here sometime next week
alex_joni: irssi is nice, but a lot of people adopt a gui client much easier
was that you with the "shoved-in CRT control" vmc
jthornton: it's too early in the morning for you to quit both #emc and #emc-devel and then just be in one of the two, there i am scratching my head if i got ZNC messed up that it shows you here after you quit :P
could have been
yeah, recognize the gnipsel
anyone use BT30 tooling?
why do so many control cabinets look like physics experiments from 1978?
jthornton: The thumbs work now btw
cradek: When I worked at a way grinding shop back in the early 80's one summer on the west side of Detroit, the standard work week for machinists in the area was 58 hours. 5 - tens and 8 hours on Saturday.
In northern Indiana shops are dying for machinists, but most of them don't want to pay much - $15-$18 per hour. Very few younger kids are getting into manufacturing so the shortage will get worse.
I think it was time and a half after 48 hours...
Well, all the jobs say "Must have 5-10 years" experience, what do you expect if you're not willing to hire trainees
Or something close to that.. those were considered standard hours back then for Detroit.. Everyone relied on overtime..
1.5X after 48 hours? lol
Yes... it did not start at 40 hours, I remember that for sure..
Dave911: impossible to find machinists here in texas too
"Good" machinists already have good jobs...
But is anyone willing to train new blood.... hell no
Dave911: when i left Germany, my work week was 35 hours, we did not get OT, but working 5x8, i accumulated 5 hours of comp time a week, so aside from 6 weeks vacation, i had 27 days of floating days, 15 i think company chose when to close (usually days before or after holidays to create long weekends), 12 days for me to use when i wanted
Dave911: good point about what kind of machinists are floating around ;)
No one thinks they can afford to.. and the schools around here aren't training machinists... they say no future .. go figure.
when i was young and the smith at work was sad that none of his sons wanted to be a smith, i never though i would be a machinist and feel like a dieing breed, then i came to the US and realized, here, i am
Dave911: that example of my work week is why we must fight that damn european socialism at all cost ,we do not want to become like that!
The US has always been a work your ass to death country ... When I worked at GM long ago, many of the skilled trades guys works 60+ hours per week on a regular basis. My uncle, a millwright for Ford worked 7 days for many years - non stop. He was making 6 figures back in the 80's but he was literally never home.
I don't think there is much chance for us truly becoming like Europe... Americans are a bunch of organized rebels ...
I should say "very loosely" organized rebels...
considering kids learn metric in school, yet there is no real push towards a real measurement system.....
rebels? hm, how rebelious is it to kick out the brits and then cling to their imperial units so hardcore? :>
Heck Texas is going to leave the union any day now.. ;-) And Arizona is right behind them.
morfic ... yeah... go figure ... ;-)
you know, in germany i used to complain about how little my pay check was after all deductions
but i also never spent much time thinking about what would happen if i got sick
when i got sick after they did payroll, i would get 2 paychecks the following month, one for that month, the other compensating for the extra money i didn't get when i was out sick
getting vacation money the month before my 3-4 week summer vacation sure was nice too
That is a problem here for sure .. if you get sick enough you can go bankrupt. My wife had a rough time last year and even with good insurance we had a $15K medical bill. The total costs were over $150K. If we didn't have insurance we would been in real trouble.
Dave911: $15K doens't sound like "good" insurance
$1500 I can see, but $15K out of pocket seems excessive
Yeah.. you would think that insurance provided by the State operated university would be better! And we chose the most expensive option for the best coverage! So much for good insurance!!
out of pocket costs are evil
Dave911: What ins company?
We hit all of the out of pocket limits, but there was a number of things they simply would not cover.
Dave911: without getting personal, what wouldn't they cover?
Dave911: yeah, that sounds familiar, wife works for State University, we have to cover out of pocket, and then there is stuff doctor wants to do that is not covered, wife went to a physical therapy session, but couldn't schedule anything for the next 5 visits, end of month we got a bill of $120something for that one 45 minute session she did make
They changed insurance as of Jan 1st. It was Signature Care last year and now Cigna this year.. The bills were split over the first, so all of the out of pockets start over again also. :-(
WTH? No PT coverage???
wow, I guess Cigna changed, they used to be good.
they all changed, cover less and less and charge more and more
Hey.. no dental coverage also, since they have a dental school.. and you can have the kids work on your teeth... seriously!!
it's all about profits, not about curing people
It has gotten progressively worse every year. The state is low on cash ... cut benefits ... University jobs used to be really great jobs ... not so much anymore..
* Jymmm ars kollage edjoomakated
you said arse!
Jymmm: >>what wouldn't they cover? You name it.. not all of the drug cost was covered.. too expensive.. the hospital room was a little too much ... that portion not covered... on and on.. it all adds up quickly. She was in ICU for 10 days..
My daughter is a type 1 diabetic.. wears an insulin pump .. and our out of pocket costs just for that are about $300 per month with "good" insurance..
Dave911: damn. Do you have ins? Maybe you can switch them to yours?
And this is with the best coverage available for a tenured Professor with a PhD working for the most prestigious Indiana state run university. I know many would disagree with me, but IMO the entire health care system/insurance racket is really broken. Anyway .. enough of my complaining.....
Dave911: Nah, it's all good... feel free to rant =)
I'm bitch about it and it's not even my problem
Jymmm: I'm self employed .... I rely on her insurance.. Fortunately at least I am very healthy .. so far. I get a cold about twice a year though.. ;-)
Dave911: an, ok
it gets even worse when Ins co's have very narrow definitions of coverage that are nearly impossible to actually qualify for
how do you measure cfm? an Anemometer?
you could get an airflow meter from a junk car
ok "cfm meter" == Anemometer
if you can get the air flow to just go through the anemometer
otherwise it's just speed
duct tape =)
velocity x area = CFM
Ok, if a blower can do 900CFM out of a 4" port, what kind of FPM would that be apx?
round or square?
I'm looking at a Anemometer that has a MAX of 5910 FPM, I just wan to make sure I'm in range.
about 900* 3.14*1/6*1/6
The fan on this meter looks to be about 2" across, that seems too small to measure the CFM out of a 4" round port, doens't it?
oops wrong 900/(3.14 *1/6 * 1/6) or around 11000
oh, then forget this meter =)
I have this dust collector, and I'm making an air scrubber, I just want to see what loss I'll have.
[15:02:07] <Jymmm> http://www.harborfreight.com/1-hp-mini-dust-collector-94029.html
I plan on using 6" flex duct to overcome the resistance.
It will be going thru activated charcoal, so I'm not sure how much loss I'll get there. It be nice to be able to meaure it
Dont they use inches of water to measure pressure drop? a bit of aquarium air line would do
that's Static Pressure..... like 250CFM@6" SP
And I'm not exactly sure have that's actually measured just yet =)
I think it's a differencial
Right. HVAC people mus have nice charts for figuring flow with varous duct types. areas and lengths VS static pressure
I guess I could just shove a weighted ball in a clear tube and see how much it rises before and after the air scrubber
hi Everyone, i would like to try out the emc2 software, i cloned the git repo, and i would like to compile source according to the instructions in README, the problem is that by running in emc2-dev/src$ ./configure --enable-run-in-place --enable-simulator i get: bash: ./configure: No such file or directory
what i'm doing wrong?
I think the water tube is better (progressive resistance VS fixed resistance of a weighed ball)
the weighted ball type rely on a conical tube
(I guess the weighted ball type I'm thinking of are actually flowmeters not pressure meters)
fossrox_: you skipped the autogen.sh step you will see on the link
thanks morficmobile and micges :)
Jymmm: a minimal equipment way to measure velocity http://www.engineeringtoolbox.com/pitot-tubes-d_612.html
pcw_home: that's for fluid, not air.
pcw_home: but thank you =)
look at the air chart :-)
Guys, how can I stop EMC2 remotely, what is the "roper" way? kill -HUP? or what? Just ni case if I forget and leave it running.
pcw_home:one question, can I use 7i33 and differential encoder signal?
Yes, the 7I33 has selectable TTL or differential encoder inputs
jymmm: heres a pitot airflow measurement design that averages the velocity across the duct: http://www.engr.usask.ca/societies/csae/protectedpapers/c0719.pdf
pcw_home: Thanks, but um do you have a "for dummies" version by chance?
well the third pitot tube in the duct at http://www.engineeringtoolbox.com/pitot-tubes-d_612.html
is pretty straightforward (about in the middle of the page)
...i got: configure: error: Required OpenGL header missing. Install it, or specify --disable-python to skip the parts of emc2 that depend on Python -- does anybody knows how the missing package is called on ubuntu?
python-opengl will be enough?
hm, i haven
hm, i haven't even used it yet, but i start to really like this back spot face tool just programming the part
Jymmm Air handling units for process control plants often use Pitot type setups to monitor air flow though filters etc and determine when the filters need to be changed. A super simple way to determine air flow. The pitot tube setup can be calibrated to actual air flow if you have more test gear. Also good for measuring static pressure from a fan. I have three static pressure U loop...
...tubes in my house monitoring a radon abatement system. They have some type of non-evaporating red oil/liquid in the tubes so along with a scale so you can easily read inches of water. Goggle "magnehelic" and you will see some gauges made to display the results.. They work very well.
Dave911: do you need the "right angle" on the tube in the duct?
Pitot opening faces flow, reference opening is at right angle to flow (parallel to duct wall)
Does it need to FACE the on coming flow, or away from it? I would thik that if there is anything in the flow, it would clog the tube.
CNCbuild is now known as mendelbuild
Remember theres very little flow in the Pitot tube (And only when flow changes) so clogging is not too likely
Pitot tubes are very reliable.. They use them on aircraft to measure air flow .. little tubes sticking out that bend into the airflow.
ok, will try a simple comparison using tube and water
I don't know about aircraft .. but I know I have never seen a filter in an industrial pitot application.. I don't see you couldn't use one though. But like PCW said, really no flow..just a pressure diff.
I have some clear 1/2" plastic tubing around here, I'll try to find some rigid tubing I can bend at 90deg and try it out
thank you both btw =)

i'll check them out at home, this "let's just update this old process to the new way we used on a similar part recently" is turning out to be a much more "fun" exercise than they expect, i am just peeking in here because i need diversion once i flipped back and forth enough between old and new process that my head spins

I could use some advice. I've been looking at the Installing EMC2 wiki page: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
and I'm not clear on chapter 2.9, the "switching from simulation to realtime" part. Do I understand that one PC must be set up either for sim or RT? I thought I'd be able (after both sim and RT have been compiled) to start either a sim or a RT config and run as appropriate. True or not?
Wait, shouldn't I be able to run sim under RT? Should I be slapping my forehead about now?
KimK: you must have rt patched kernel to compile rt emc
you can run sim both on standard or rt kernel
OK, so I *should* be slapping my forehead, lol! If I compile for RT then I should be OK on a sim config, right? (I'm just building as in chapter 2.5-2.8 using the mozmck-supplied kernel).
And if I click on a RT config, it will run OK.
yes and yes
Ha, thanks! I'm not sure why 2.9 confused me like that.
KimK: what hardware is this on? (just wondering, because building was easy, had i known it's a bios option that was causing RTAI to freak)
geo01005_home is now known as geo01005
morficmobile: This is on an AMD64, but I have installed (...as in finally ended up with after going back-and-forth...) i386 (Ubuntu 10.04) because of EMC2, RT, etc.; I was advised that the i386 version was the way to go. And so far it's been good, I'm just getting everything set up the way I want it now.
KimK_: cool, figured i check, seeing how hardware can make a newb wonder where he missed a step, when in end, nothing was missed. i might make me a little 32bit chroot somewhere, just for sake of being able to compare, i built it all on my 64bit install, i just built it because i wanted to see how well newer cpus work with all the extra effort of power savings and what not.
So you went with a 64-bit version? Which one? And how did it all work out, both for the OS generally and for EMC2, RT, etc.?
Fox_Muldr is now known as Fox_M|afk
whee, I cleaned and disinfected my coolant tank and put in new coolant
that's good to do every couple years whether it needs it or not :-)
was it getting a bit smelly?
it was getting thick/clumpy
the flow would go down sometimes when glop got stuck in the tubes
glop = scientific term
fortunatly i dont run coolant :)
it didn't ever smell that bad, but it was getting "weird"
heh it's sure nice to have
kinda makes a mess of composite cores tho
ah, I cut 98% aluminum 2% steel 0.0% anything else
i do rohacell cores, epoxy tooling boards and carbon
although i am setting up a seperate area for wet machining, so we can do ally
