yeah :), but remember to enjoy your elephant too.
will listen to some jazz in the music room and read the stg manual
ha later...nice talking
take care :)
what did I miss over the weekend ?
* jmkasunich barely remembers
Jonathan Stark and I have started the hal refactor
Alex is working on IO for emc2
plenty of the usual conversations
got any use for Allen Bradley 1394 AC servodrive axis modules?
with motor ?
I have 8 motors and 15 axis modules
motors have integral encoders
rated 1Kw cont, 5000 RPM, 24 in-lb IIRC
been skip diving at work again ?
they must have cleaned out a development lab
the power supply/control units were definitely engineering prototypes
one had the side panel cut away so they could probe the board
and the boards have the usual cuts and jumpers and "not for customer use" stickers
but the axis modules seem to be standard production units, right off the shelf
the control units aren't really interesting to me - they speak some proprietary AB protocol, completely closed source
Hmmm... Sercos inputs ?
who knows - the system is modular, and AB has many flavors of control for it
[02:27:39] <jmkasunich> http://www.ab.com/motion/drives/1394ac.html
the wide chunk on the left is the control/powersupply
the others are axis modules
I have three of the power supply units, but as I said, engineering prototypes of unknown origin and condition
much as I would like to play with them.....
I don't have a three phase supply
you have 230V single phase?
nor do I think I could afford shipping charges.
I'm planning some experiments running them at half voltage
* paul_c has 240V single phase supply...
that should get me 2500 RPM
would require some hacking, but guess what... I know an EE who works on drive stuff much like this ;-)
I have schematics for the axis modules (but they are proprietary, I couldn't share without endangering my job)
re: shipping... I might bring some to fest
axis module is about 2" wide x 12" tall x 10" deep - not to bad
motors are bigger than NEMA34, but perhaps a bit smaller than NEMA42
be a far bit of weight in one motor..
5Kg perhaps... would get heavy fast in luggage :-(
on top of all the other stuff I'd be hauling...
get some interesting looks in the airport too ;-)
Any news on a venue for the Fest ?
no reply yet from Fred
* jmkasunich gives Fred a call
* paul_c scans the irc logs
wanna be carefull with kmalloc
'eck... They're all turning up.
Fred confirms that we'll be able to have several days at NIST in April
he's promised to check his schedule and send me some tentative dates tomorrow
one minor bummer - we'd be limited to 7am-7pm, mon-fri
I'm going to be away for a while, so I may not be here or on IRC to discuss dates.
no late night debugging sessions, and no using the weekend to minimize vacation days
gonna be reading email?
probably (as & when I can get n/w connections)
well let me know if you have any dates already known to be good or bad
I seem to have been volunteered as coordinator for this thing, so....
we probably should avoid NAMES weekend, so if some folks want to make an appearance at NAMES they can
I was going to suggest the week following NAMES - Those that attend are only 10 hours from NIST
the week before would work too, for the same reason
re: motels - Avoid Red Roof....
the one near NIST is right next to a railway line.
thanks for the warning
NIST has a big list of nearby lodging on their website
Motel 6 should be pretty cheap
no Hooters on the restaurant list tho...
there's a couple of other food joints near by.
Hi guys, I'm on the phone with Ray H. and echoing your comment by voice.
what do you and Ray think of the week before or after NAMES?
BTW, does anyone know the dates for NAMES?
last weekend in April ?
April 23-24.... Ray says fine either before or after.
Steve, are you gonna be exibiting at NAMES?
you'll need to get there Friday then, to set up? or Thursday?
Nope, early Saturday.
Sounds like our preferred dates would be Mon 4/18-Fri 4/22 or Mon 4/25 - Fri 4/29
or some shorter period in there
Cradek would be coming from Neb, I expect he'd like the idea of being able to stop at NAMES while in transit
Ray likes the idea of EMC programmers meeting at NIST and integrators at Roland Friestad's meeting during the weekend.
and Ray would drive right past NAMES as well
at Rolands during NAMES weekend?
Ray mentioned combined trip to NAMES/NIST.
No, Roland's during his show.
sounds good to me - that makes it two different events
so if I wanted to go to the integrators meet I could
one big event stretches work and family too much
hey Steve: ask Ray if he has any use for AllenBradley 1394 AC Servodrive axis modules or matching 1326 motors
he might service machines with that kind of stuff
duh, sure, guess I could pick them up at NAMES
have him call or email me for details
oops, that was a quote from ray
need phone number?
he says he has #
Is he joining in on IRC later ?
he says you twisted his arm, guess I have to hang up the phone....
The reason I had called Ray was that the ISO images at Sherline seem to be off line and I was worried that since Mike Joyce was gone, things might be changing. Ray said, no Joe was still committed, probably just a machine down.
any preferences for before vs. after NAMES anybody?
* jmkasunich is writing an email to Fred
I can do either and would defer to Ray's needs.
I believe I can do either as well
a yuoper ?
No idea who bobh is but ray is here in disguise.
My knoppix went belly up earlier and this is the result.
Ho Wah! Yah 'eh.
yep, whois confirms up.net is the source 8-)
So tell me how do I change nic in mid stream?
The guys want to know if Ray prefers the weekend before or after NAMES for trip to NIST.
* paul_c is compiling two new kernels side by side...
I would guess that that must be illegal here in Virginia......
bobh is now known as rayh
That's better, eh.
What two kernels is paul compiling side by side?
188.8.131.52 & 2.4.27
Athlon test cases?
You know I've got 4.08 running on athalon here and running a Sherline box.
Ray, did you hear the question about your preference for NIST trip before or after NAMES?
I'm thinking. I'm thinking. To quote George Burns.
What about your logistics, Steve?
Either works, I'm almost local to NIST.
I don't know. I guess I'd rather short Names by driving sunday to DC rather than the other way round.
so you'd prefer after NAMES? Paul said the same, everybody elss had no preference
But the issue is getting from detroit to DC.
We talking about 10 hours?
no, it shouldn't be that long
NAMES closes at 4 Sunday. Get to Nist at 2
I did a mapquest from my home to NIST, it was 5-1/2 hours
NAMES is about 3 from me
so 8-1/2 from NAMES to NIST
I had not considered the idea that NIST would be the very next or previous day. I will be in Columbus on Friday and dead on Monday.
I should be able to make that in 7 if the fuzz isn't watching.
much of it is PA turnpike - they'll be watching
Would we want a week between?
How long do we want at NIST?
we will only be allowed to be there 7am-7pm, mon-fri
Well NIST must host during weekdays.
no late night debugging sessions (unless at a hotel room)
I'd be game for a full week
That woluld work for me if we all get near one another.
but could live with as little as three days
less than three would be a waste, IMO
Maybe Thurs/Friday after. Then hard core could lurk off to MD or VA over the weekend.
Or M-th before
if NIST was willing to give us Mon-Fri, I'd take it... not everybody has to be there the whole time... I can understand that Steve will be toasted after NAMES - the first day will be mostly about getting set up and planning anyway
Being a real estate agent perhaps Matt could get us an empty house for the stay. We could "animal house" the whole time.
if he could do that, we don't need NIST!
Matt's house is an animal house, lots of cats....
I suspect we'd be a bit much for the stately Shaver's.
I'd rather have a hotel room within a short distance from NIST
Not really hinting at that. Hotels make more sense, just expensive in our area.
don't want an hour commute each way (Matt is probably more than an hour from NIST, right?)
even the likes of Motel 6?
Monday -Friday before would be okay with me. We'd just have to plan ahead for those going to NAMES.
Well, it may be OK if you go away from the city instead of towards it.
before better than after?
How bad would that cramp your style, Steve?
After works better for me because I am always in a panic getting ready for NAMES.
SteveStallings: how far is your home from NIST?
1.5 hours in rush hour
you might just want to go home from NAMES, crash, and show up at NIST on Tues
I will likely go home, pop into the office, then head up to NIST.
hmmm... motel 6 is only 0.4 miles from NIST
Check the rates at that one, and then others up I270 a ways.
After would also be fine for me.
57.99 per night, one person
I seem to remember staying at Red Roof Inn and it was $100+
I like it, things would be ironed out by the time I get there.
Sounds like motel 6 is it. Sure that's not the 4 hour cialis special?
paul warned me that RedRoof was near the train tracks
Right and my room was on em.
I doubt that motel 6 has a meeting room.
"free coffee in the morning in the lobby" ;-)
Are we agreed that after NAMES. Starting Monday morning at NIST and primary motel is 6?
sounds good for a start
gotta make sure those dates work with Fred and NIST
Good. Let's try to float such a meeting.
Good for me.
once I hear from Fred I'll post on the dev list
I wasn't planning on announcing on the users list
Good deal. I'll get a note out to users about Roland's event and our participating.
Motel 6 has some stuff about group rates... perhaps I should look into it
Do. We've got a bit of time to see how many are interested. Count me in.
group rates are for 10 rooms and up, but the people pay individually, so we don't have to worry about one individual getting stuck holding the bag
you have to call them for details
That sounds good.
getting late here (for a workday)... time for bed
I'll follow up when I hear from Fred (or poke him if I don't)
Obitz.com claims to have a special at $68 for Sleep Inn in Gaithersburg, nothing else is even close in price.
Oops, make that Rockville
I've gotta get going also. Let's talk a bit about invitations next Sunday.
I was just reading some fine print at the motel 6 site... the rate doesn't include taxes
do they ever ?
Still not bad.
so 57.99 becomes about 65
$260 for Mon-Thrus nights
(assuming driving monday morning)
jmkasunich: You want to pass this by Matt also.
you mean before it hits the list?
Perhaps while we are waiting for Fred P.
ok,I'll send him a mail either tonight or tomorrow
Tell him he can share my room as usual.
If he needs a place.
do you know if he still reads the erols email addy?
Time to bake bread.
Time to saw logs, later....
email top Matt posted... bedtime
Time to hit the sack for a couple of hours.
CIA-temp065 is now known as CIA-3
Hm...maybe I should just bring a tent and camp in the bushes
CIA-temp806 is now known as CIA-3
it's 3:30am here. :)
and I'm trying to watch TV, and fall asleep... with the laptop on my bed...
I like late hours myself...
but.. I hate myself for that in the morning
yup... I'm gonna turn in now... or at least try to.. and wake for 10am [try again]
alex_joni: P was already set to 1000
anon: was a thought
no idea what happens...
did you try emc2?
is it ready enough to make parts with?
I'll bring some rj45 home and hook the box up :)
and install it this afternoon
or maybe night.. depends if I get time
emc2 should be enough for making parts
what still is missing is IO (coolant, lube, spindle control)
but you can use start/stop on the spindle
can't controll the speed thou
:) that's not important yet
I need to mill some coolant blocks first.. :)
if the user is there (you)... I might be able to code the stuff up
if you get to test it ;)
as I have no mill here ;)
what I mostly care about is the possibility to run cam since none of the stuff I play with is somthing I'd write by hand :)
I did find a few programs for cam, and gcode output
sheetcam (windows version, beta-version)
I use visualmill
so I guess I could write a post easily..
but well that wont help if I cant get the machine running :)
did you try to hook a scope to it?
didnt feel too well so I went to bed :)
I cant take any test cuts without getting the mill running
oh the cable.. no..

paul_c: any luck finding that rtai-problem?
No - Not had time.
bummer... any idea when it appears?
I haven't seen it so far...
just start EMC up and home an axis.
only on athlon? or any processor?
CIA-temp691 is now known as CIA-3
alex_joni: Turn off your away flag.
sorry..forgot about that
CIA-temp909 is now known as CIA-3
Paul: checked stg watchdog function
all that is required to keep it from timing out is writes to the card
les: what's the difference between wood tools and toold for milling metal?
and can you mill wood with metal cutters ?
anon: the difference is rake and clearance angles
you can mill wood with metal toos
I've got some molds to make that's going to be used one time..
performance and surface finish might not be as good but it will work
I'll have to hand prepare them anyway..
but fibreglass + wood is better then fibreglass and foam
make with ball end mill?
I'll mill em with a normal one.. I
I can do so small stepover that you cant feel the ridges..
use a 2 flute if you can
the ball endmills i have are very tiny.. and short
I might have some 2 flute endmills somwhere
Paul: is there any instance where emc is running and it is not continually writing to the stg?
but well, I am not going to mill that today..
too tired :/
I'll be tired too later
les: At startup before you come out of e-stop & machine-On.
anon: got your mill running?
right now having to change a tool path to compensate for wood shrinkage
alex_joni: no been off work half day sick
Paul: So that is the only place where a loop with some write would be needed?
les: or initialize the watchdog when switching the machine on
not from the beginning
that would seem a bit dangerous
Would need to check the code - There is some hooks for watchdog timers that can be expanded on.
hmm writing a 0 to the wdtout bit of cntrl1 register might do it
not sure if it's latched
les: the reason I asked about the tools is hwo does speed/feed compare to milling metal?
speed/feed is much higher with wood tools
higher than your spindle will go prob
Oh...writing a zero STARTS the timer
so that must be done when coming out of initial estop
i'll be back later need to rest
alex_joni: I might make a test cut, if I manage to get my father to grab the scope.. unless he's home already
where is that...emcmot?
yep, he'll bring it off my desk :)
need to find the switch() that looks for estop off
les: estop off is in io-controller
you can also hook in emcmot
* alex_joni is looking
Paul thinks there is something in there already
alex_joni: is there anything like a deb off emc2 ?
anon: the BDI4.08 is deb based
and paul_c has a repository with all the stuff
the box isnt connected to the net
I thought about getting all stuff and moving it on a ce
get emc2 from CVS
and burn it onto a CD
what's the password for cvs?
les: there is a wdEnabled
(an0n)[/home/an0n/EMC]$ cvs -d:pserver:email@example.com:/cvsroot/emc login
Logging in to :pserver:firstname.lastname@example.org:2401/cvsroot/emc
just hit Enter
dosent hm, ah must have written somthing the first time i tried it
les: the watchdog code in emcmot is for a soundcard based watchdog !?
ah it's downloading nicely now
alex: right...looking at that now
hm, I should try grabbing a copy of fvwm2 to the mill box aswell
kde isnt fun on a 200mhz box
anon: I use windowmaker on a 300 Geode (kinda 233 pentium) and it works ok
well better get out to the shop
alex_joni: yeah but it's not as heavy as kde..
will ponder this watchdog later
alex_joni: the task switching with kde is horrid.. it's still images..
alex_joni: I am fvwm2 freak :) it's the fastest there is almost..
* anonimasu have never heard about geode
my millbox is a pII 200 with 320mb ram :)
Hi Paul, Wow, how exciting this IRC is!
first time ?
I've been emailing John K about an EMC code-fest here at NIST.
And this is my second time, if you count the time I spent with Les Watts in Georgia.
We were bouncing a few dates around last night
anon: it's a compact processor from National Semiconductors
alex_joni: ok :)
John suggested the week after NAMES for the code-fest, which would be April 25-28, Mon-Thu.
* paul_c suggested the week after NAMES
I have been emailing John K, but we should move this to the EMC developer's mail list.
Holding a Fest at your place is OK is it ?
Yes, it's OK. I have alerted our IT people and we should have Internet connex for everyone.
I will need to badge in the attendees, and will need company name and address for you non-US citizens.
Visitors should be in after 7:00 am, out before 7:00 pm, so no coding to midnight unless I'm around as the "escort".
nail you to the door ?
I'll get a life-size cutout.
this sounds fun. I hope I can make it.
Hopefully I can nail this 2.6.9 related bug before then...
I suggested to John K that we get an agenda set up ASAP so I'll be able to prepare.
Presumably there is a list of things to be accomplished; support for lathes comes to mind.
* alex_joni wishes he could make it too...
Would there be any chance of some big iron to test code on ?
I have a Bridgeport servo mill that I'll resuscitate. I also have small iron, the Sherline mill.
And the Sherline lathe the students worked on.
the BP still wired to an STG card ?
I would bring my homemade mill if I drive
The BP is on an STG card. I have a Vigilent on my chair here but I have not hooked it up.
* paul_c makes a note to pack an STG card with the luggable computer.
While I think of it....
Do you recall that Qt GUI you were working on when I visited ?
We did a Qt GUI for another project, but I never wrote one for EMC.
A cable platform as I recall...
Yes, it was a large cable robot used for depainting KC-130 aircraft. We used Qt Embedded on a PC-104 with Linux/RTAI.
* alex_joni has to leave for 10 minutes..
was there any plans to release the code for it ?
Interested in the NML<=>Qt hooks
The code is public domain. Will Shackleford has the latest version. I'll ask him about Qt-NML hooks. I don't know that we did this since the controller was not an EMC.
Will just did a port of NML to Python also.
That will interest jepler & cradek
nah, ours is done
but it does only exactly the things needed for the gui
Now that I think about it, can't you just link in the RCS library with your Qt code? Qt is C++-based and you should just get the NML functions directly.
For cradek: how did you get Python and NML integrated?
link an extension with emc libraries
it gives a stat channel, error channel, command channel in python
Will did the same thing, I think; he made some association of string names to NML format functions, so it was a bit cumbersome to support multiple NML vocabularies.
Chris, did you do a PyTk GUI?
jepler and I did, yes
[15:46:33] <cradek> http://axis.unpy.net
click "about" on the left for screenshots
OK, thanks, that looks nice. I'll have a look and let Will know.
OK, got to go, meeting at 11 EST and 10 minutes to prep...
* alex_joni is back
les: is homing working now?
CIA-temp956 is now known as CIA-9
hm, emc2 wouldnt compile..
need to get that net connection out so I can grab the deps for tk..
which distro ?
I have no idea what it was
the kernel is 2.6.9-adeos
it seems to lack some deps
You need kernel-headers, tcl8.4-dev, tk8.4-dev, and a few others....
Oh, and a set of make fies - But there is nothing in the main emc2 tree that will compile against a 2.6 kernel yet.
* anonimasu sighs
The alternative is to download the Developer's Toolkit CD when it becomes available.
hm when's that?
I saw this show yesterday called "how it's made", and one of the topics was endmills. The process of making HSS or Tungstun Carbide endmills is really need.
another 6-8 weeks at the earliest.
that's way too slow..
* paul_c is leaving the country tonight.
paul_c, where too?
if you're coming to Toronto, let me buy you a beer. :)
evil... nm then.
paul_c: wont emc2 compile with all deps satisfied and another kernel?
Toronto is buired under snow at the moment isn't it ?
hmm... if I put a 16mm OD dia bearing in the freezer for a few hours... think it'll shrink 0.02mm?
warm the part also, and you will be lucky..
paul_c... well. yes. it's quiet beautiful. it's under 6" of snow. which I just shoveled.
anonimasu: Any RT patched kernel from 2.2.xx or 2.4.xx series.
although 0.02 sounds pretty much :)
paul_c: ah, well then I'll just have to get a rj45 out into the shop
A-L-P-H-A: Way too cold for me.
anonimasu, the part is Al 6061. The bearing really needs to be 0.01mm down in size...
a-l-p-h-a: yeah but alu expands more then bearings shrink..
toaster oven for the part AL6061 ~350oF? and freeze the bearing?
or should I get some dryice? [where now do I buy dry ice?]
although I dont know if you'd need it that warm..
I've turned parts you could warm by hand until the bearing went into them.. :)
I've got an arbor which I could just _PRESS_ them together.
cool the bearing heat the part a little bit..
anonimasu: Have a 2.4.27-adeos kernel & rtai package built - But haven't tested them yet...
so what distro will the next BDI come out on next?
I can dualboot so it's no big deal really
other then getting network outside
I'm committed to Debian for all current work.
debian's good.. since upgrading is easy
No more RedHat/Mandrake/SuSE rpm dependency nightmares..
well, you dont need lots of deps and stuff for a mill :)
how does the performance of emc/emc2 compare aginst some commercial controllers?
if it were just EMC that people wanted to run after a BDI install, many of the extras could be left out...
well, as long as emc isnt production stable.. it's desireable..
my oppinion is that the controller of the mill should be dedicated to just doing that :9
maybe some integrated cad/cam/online programming in the interface like I think fanuc has..
I think it's fanuc, I saw somthing like it at a shop over here
they loaded a igs and just programmed the operations online... at the panel..
selecting a hole and mask on arc...
When comparing EMC to other systems, do you mean off the shelf products from the likes oh Heidenhain & Fanuc, or hobby level products like Mach (and it's ilk) ?
GREAT! start_wp() is depricated. But what's replaced it?
oops, wrong chan
paul_c: or haas..
paul_c: or any other commercial controller
Not fair to give a comparision - Most high end controls don't use comodity PC for motion control.
If they use a PC at all, it would generally be for file IO and HMI.
anonimasu, think putting the part into boiling water would be good enough?
your toaster oven can get much hotter than boiling water
k, toaster over it is then.
and most real ovens can get up near 600F
(not that you need that)
paul_c: I thought they used pc's with controller cards..
still I am curious
paul_c: I am talking about emc + stg/vital
with a fast computer..
'bout the only thing that springs to mind would be something like OpenCNC
ah I've seen it..
EMC is the only package available that is truely open source.
paul_c: I was more concerned about servo cycle time
never used OpenCNC or any of the latest controllers from Fanuc et al.
if you can compare that
featurewise dosent matter that much
let's have a look at the opencnc spec sheets...
1,500 blocks per sec... 500uSec or less for 10 axis.
max program size: 4Gigs (limited by available memory)
does emc have that?
will it have it in the future?
If someone wants it bad enough, maybe.
does emc have lookahead?`
now compare the price.
paul_c: I dont care for the price really.. :)
fanuc wanted to sell me a system for 5000eur
+ 1000 eur per axis..
I dont belive that
for my hobby mill.
ive seen fanuc charge over 5k for a simple upgrade
gezr: that was the cheapest.
fagor would be the cheapest or least expensive route to go
[21:11:33] <paul_c> http://www.low-cost-cnc.com/ll_shortoverview.html
2200Eur for the base package
what's adaptive lookahead?
A high speed machining stratagy that adjusts feedrate and tolerances acording to a set of rules.
for example - Want max feed rates, but can tolerate =/- 10thou
for roughing cuts.
I'll be back in a sec..
but for finishing cuts where you need close tolerances and can afford lower feedrates
ah Fred was on earlier
then the control will adjust to suit the rues.
anonimasu : so fanuc gave you a good quote hu? thats a really good price for one of their packages thats for sure
paul_c : I finished lapping the valves last night :)
now to shim the valve clearances...
time to buy some service manuals :)
I had mabye 4 good seats, the rest required quite some work
gezr: lol.. 1000eur per axis isnt good..
after blueing, I had an acceptable closure, the pits seemed to be clear of each other, so I felt that was adequate, and when holding the valve up by hand, no alcohol was able to pass
anonimasu : its not?
gezr: it's for a hobby mill
for a comercial control its damn good
gezr: I dont mind spending excessive money..
anonimasu : well hobby and comercial are different ballparks, hobby is cause you can, comercial is cause you need to
gezr: Track down a Clymer K100 manual.
paul_c : you think I wont need a technical manual, 100 bucks new
paul_c : a new clymer is 34$ so thats not too bad, ive seen em used on ebay recently in the 20s
* anonimasu sighs
anonimasu : sigh?
I just want a good controller that will let me run stuff form my cam program..
at perferably very high speed..
anonimasu : how high is high ?
gezr: The Clymer has all the info you will ever need... The genuine BMW manuals are just too expensive.
gezr: perferably as fast as my servos will go.. :)
paul_c : thats what I was thinking, I may have found a better parts supplier, they ahve a photo of what im rebuilding
[21:56:09] <gezr> http://www.autobahn-craftwerks.com/BMWK100.html
I have no idea how many mm/min that will be
my faring is long destroyed
the ballscrew is a 5mm screw..
and the gearing is 4:1
anonimasu : emc should be able to provide you with what your after
maybe im wrong
the encoders are 1000 line encoders..
paul_c : that picture almost makes me want to cry, thats the same donalite green as mine too
anonimasu : how many hp, does your spindle have?
gezr: right now 2
soon to be 5
anonimasu : on a bridgeport iron type machine?
anonimasu : have you seen a modern control working in high speed mode?
comercial type that is
not very much..
I guess a small diameter cutter could really really fly
just a bit at a shop over here..
anonimasu : its awsome
well, the limit right now is the speed which my computer can output to the geckos..
but they are to be replaces by a vital card....
thats gonna give you a considerable increase in performance I guess, I dont know much about the i/o cards
oh, just to move the pid to emc instead..
anonimasu : you will find that you will be able to drive your machine at an unsafe speed because of the machine
how fast mm/min can I expect?
I dont know, but pending cutting tools and such 200ipm is gonna be super fast
even at that, you ahve to take into considerations as far as hp, machine stiffness, stuff like that
total of 200ipm
thats about right
the most I've been running right now is 1000mm/min
thats the rapid speed of the machine i run at work
200ipm, ive ran machines that cut at that speed
the one Im on now is a year old
I guess I dont need that kind of extreme speed..
although I love watching when it's going fast..
yeah you do, ifyour using a .25mm endmill, wacking away at a block of aluminum
light cuts and very fast speed.. for roughing
tool life is baised on time, not so much depth of cut
or well, not too heavy ones..
I dont have good cooling yet..
dry machining using coated carbide tooling or cermet type inserted endmills :)
alu becomes gummy pretty easily..
* anonimasu havent tried any of thoose
just dormer hss endmills..
and ghuring ones..
I think they are hss atleast..
* paul_c loves his tcmt inserts

anonimasu : seriously, if I had a choice, ide own a comercial machine, but I dont have that option nor budget, so anything that keeps me from turning a crank wins
endmills like that
they are great
anonimasu : whats the smallest diameter tool you plan on using?
it depends I guess
I tried milling some hardox 500 with one of thoose cutters....
alrighty, whats your spindles expected max rpm?
which should be way too hard :)
the spindle which I am looking at goes to 10000rpm
but with the belt that'll be a bit over that
a 2mm endmill at 10krpm in aluminum, with .002" depth of cut or chip load per tooth 4 flute needs to move at 80ipm
depth of cut doesnt matter could be 0-max
hm, my machine could do that now..
although at 6x at the geckos..
you still dont have any where near the spindle speed to properly run that small a mill
small a tool
the speed I have now are about 3000rpm..
so your real limitation isnt the control
while fast is really neat, it comes at a high price that is incured long before a control is even considered
thats where emc comes in, you can spend a bit more on better spindle bearings and the likes, and use something that performs, have you tried the changes made to segmotqueue ?
emc wont run :)
my step output dissapears when I run in the opposite direction
AMD K7 processor ?
something about that doesnt seem right,
[22:19:48] <anonimasu> http://www.solectro.se/Products/Product.asp?ItemId=726&SectionId=520
your saying emc runs but when you reverse direction, you dont get a step signal?
I get a direction signal..
but no step
somthing like that spindle motor
did you check the parellel ports configuration in the bios?
nevermind, im shooting in the dark
hm, you mean the address?
bdi-4.08 install ?
no not the address, im talking about ecc/epp modes stuff
ah no I didnt, but I've been using the port for running my mill with turbocnc earlier
might that be the problem?
are you booting emc from the hard drive?
or using a vmware type thing?
I am booting it
It is more likely a product of a bug I'm tracking in the homing sequence
cold or warm booting
dosent make any difference
I dont know what to say
I'll go out now and chech ECC/EPP.. on it..
anonimasu: Can you email me a bug report & attach your ini file ?
paul_c: it's the one that follows with emc
setting up my axis:es and backslash dosent make any difference.. to it
and emc doesnt error, did you take your scope home like you were talking about?
and on pin 3 when you reverse dir, the signal just stops?
i think thats X
I havent hooked up the scope..
I could go out and do it now
gezr: Has nothing to do with X
it wouldnt take many minutes
It is a bug - Probably in the parport driver that I had been hacking about.
I can measure it and export you some logs of how it looks on the scope..
if you want :)
but that'll be when I get back from work tomorrow since it's night here now
anonimasu : I think Paul is saying its a bug to that version
gezr: ah.. so it's been solved, or still in the works?
mail me what ever you can dig out - I'll take a look at the code and run some tests from this end.
anonimasu : I think he is working on it now
what's your mail?
bdi-emc @ ntlworld . com
I'll get you them tomorrow after work
anonimasu : if you want, I could help you install emc from source this weekend
it'll be ok.. I've been running linux for a couple of years :)
there's a choice of 2.4.27-adeos kernels in my local repository...
I'll try switching the computer tomorrow since I have a spare 600 laying around..
That would save you the hassle of patching & compiling.
hm, that would be even nicer :)
lemme upload them...
hi,may i ask a question please
how good does one need to know linux to be able to use emc?
is there a document about compiling kernel with adeos patch for debian sarge?
Can you use M$ ?
You can use EMC and linux then.
áand the support is better
acemi: I don't know of any specific docs.
Mer: Gogle for a local Linux User Group in Belgium
acemi : you can get pre patched kernel source in a .deb
* paul_c will have a source package uploaded shortly.
i know but i want to try
I think its pretty simple
patch -p1 < rtai.patch
acemi : standard patch -p0 < patchfile from with the top dir of your linux source tree I think
thats right -p1 my bad
make-kpkg --revision foo binary
do i need make-kpkg --added-patch adeos ?
and if you feel lucky....
make-kpkg --revision foo modules
* paul_c patches by hand...
wife is home whoo hoooo
manually patch, then run "make configure" to ensure the correct options are used.
tip: MAKEFLAGS="CC=gcc-2.95" make-kpkg
paul_c : yeah , I had to change everything back to 2.95
[23:24:08] <gezr> http://www.omsmotion.com/products/products_index.html
is that something emc uses or ?
nuts.. run out of space.
gezr: No... Although, if you wanted to program a driver, it could..
paul_c : you know I wish I could
I had to walk the dog, im looking at there stuff
hmm, it seems to be a complete solution thing, not an io card
onboard DSP - It is going to be $$$ to boot.
I get a newsletter from motioncontrol.com and I just clicked through a link
paul_c : with emc, we dont need external processing all we really need is solid i/o right?
I mean there is much more involved, but since were providing the motion, all the card really needs to do is output the signal, not generate a path
right - simple IO...
[23:47:02] <gezr> http://www.accesio.com/go.cgi?p=../pci/lpci-a16-16a.html
linux is mentioned on that page
that thing isnt cheap
[23:50:26] <gezr> http://www.accesio.com/go.cgi?p=../pci/lpci-a16-16a.html
that may be something les would be interested in
or anyone really
and coded into the emc so that, a final word per say could shut things down if something went wrong
the STG card already has A2D on board
im just looking about
im talking about a secondary watchdog
not the i/o
oh wiatits pretty much the smae line
same link, that acessio site has some watchdog type cards
my bad in pasting the same link twice
I dont feel very healthy today, somethign wrong with my ear, so im just relaxing and thinking
