the only thing that i am a little upset about so far re: obama is that he is all for mandatory volunteer service for hs/college
i am going to throw a fit if that becomes a reality
toastydeath: it'll do ya some good
i hate volunteer work, i had to do it before with homeless people
now instead of a general feeling of ambevelence, i want them to starve
toastydeath: And if you throw a fit, we'll just let you volunter to work with the kids that have motor contorl impairments, you'll fit right it
nobody will notice if i push them over.
it'll be the perfect outlet for my rage that I'm there in the first place.
oe they push YOU over
I'm not actually motor impared, I assume I can dodge.
though i guess there might be some motor-impaired savant who has superhuman reflexes
against whom i stand no chance.
It'll be a toastydeath gang bang
i wonder if there's an actual requirement to do anything
Then you'll get on You Tube
or if i can just hold a broom and stand there for a couple hours and go home
you'll have to clean up the puke
"Set goals for middle-school and high-school students to serve 50 hours a year of public service, and for college students to serve 100 hours a year."
that's the actual text
i'll stand there and contemplate cleaning up the puke
so it says nothing about it being mandatory
swplinux: that's not the only article about it, and he's stated that he wants to make federal funding dependent on attendence
so if the students don't show, the college/hs doesn't get funding.
where did you read that?
on other sites when I googled it
he's commented several times, not just once.
you need to check your sources. try using something like http://www.sourcewatch.org/
(we all need to check our sources - that's not meant to sound accusatory)
okay, except I've read the quotes, from him talking, on news websites
which news websites?
i didn't think i needed to check direct quotes, but i guess i do
i don't have a list in front of me or i'd have linked it
it's amazing how little truth and how much bullshit there is on the web
and in print or on TV for that matter
i understand your criticism, but having seen it in several places that were not someone's random blog, i'm going to believe it
i'm googling it to try and find the one that stuck out
well, I know there are a number of things I looked up before the election (Obama is a treeorits, Obama is a Muslim, Obama is a ...), and every one of them was false and/or totally blown out of proportion
i understand that
even John McCain was repeating the bullshit (for instance, that Fannie Mae and Freddie Mac were among the highest contributors to Obamas campaign)
(which I checked today, using the source he cited, and found his claims to be false)
i understand that
the same quote, attributed to obama, in several places, was compelling enough for me
ok, I'm just giving you another data point on that situation ;)
geez it's not like they're sending you off to vietnam
SWPLinux: did you really work on tanks?
not designing them or anything, just repairing some parts
[01:20:41] <toastydeath> http://www.latimes.com/news/opinion/la-oe-goldberg8-2008jul08,0,368008.column
the quote in that article is exactly as I pasted
[01:23:10] <SWPLinux> http://www.sourcewatch.org/index.php?title=Jonah_Goldberg
I'm not positive it's the same guy, but he has the same name :)
the actual policy statement (but not the actual legalese) is here: http://www.barackobama.com/issues/service/
yes, i read that too
and I didn't see anything about withholding funds in my scan of that
and it doesn't include the withholding funds part
they may be spinning the "25% of work study money to be used for service jobs instead of cafeteria work" as withholding funds
because he said it at a campaign speech
and regardless, I think it's true, but at the same time I hope you are right
it would be very nice to be wrong on this issue.
well, I just get annoyed when I see people (apparently) go off the deep end because of something some spinmeister (on either side) said somewhere
not that you're off the deep end, but it sure seemed like it got your blood pressure up :)
my blood pressure is up
see! I was right!!!
but i've seen it enough from obama supporters that it concerns me.
that one link is hardly all, but it's what I found at the moment
sure. I'll look into it more, even if you don't (I'm like that ;) )
I think it was 1000 hours hours for college
this may be a more balanced analysis of the policy (but still no source cited): http://www.politico.com/news/stories/0708/11961.html
we needed 140 credits or so, with each credit being 1 hour of class per week for 15 weeks
so 2100 hours or thereabouts
(over 4 years)
swplinux: that would be awesome if there's just going to be money around for that kind of program
i just want to make sure I don't have to be part of it.
can I find help for Xenomai here ?
boulabiar: probably not. we only use RTAI
boulabiar: Try theri mailing list http://www.xenomai.org/index.php/Main_Page
isn't Xenomai more up-to-date ?
why do you use RTAI ???
because it was there when it was needed
xenomai is newer, and EMC2 could use it, but nobody has written the interface layer for it
(patches gratefully accepted :) )
toastydeath: here's the source document I think - let's see what actually happens: http://www.barackobama.com/pdf/NationalServicePlanFactSheet.pdf
sorry but what is EMC ?
it's longer than I wanted to read tonight, but I didn't see anything in a scan
EMC is a machine controller
we were havign a political discussion earlier though :)
boulabiar: RTAI/Xenomai was recently discussed on the mailing list here: http://thread.gmane.org/gmane.linux.distributions.emc.devel/1342
swplinux: part 2 has the stuff
depending on how you want to read it
there's a 4000 dollar tax credit for college, rather than compulsory
Enhanced Machine Controller = "is a machine controller" ???????
have you looked at http://www.linuxcnc.org/
I am there now
oh, you're looking for xenomai only help, not related to EMC (I get it now ;) )
toastydeath: yep, I saw that part, but forgot to point it out
well since we cant help you, perhaps you'd like to stir up the political discussion :)
it's not as bad as it was made out to be, thank you swplinux
any time :)
american culture tends to over-exaggerate things
specifically far left and far right commentators in American culture
well, from what I read in this, it will be mandatory for highschool
which does not make me happy at all, but obviously doesn't affect me directly so the impact is less
i dont see why it's a big deal when high school is practically mandatory anyway
fenn: so does toastydeath when he has to get off his butt =)
because i had to volunteer in highschool and it was awful
I didn't see anything about a requirement, but I do see the phrase "should be expected to do 50 hours ..."
that's why i care about it
so I can see how people would overreact
have you read "Starship Troopers"?
well i thought high school was awful in general so i'm not surprised that extra high school is more awful
SWPLinux: hah that's what i was thinking
i have not
stupid movie, different story with the same name
what's the reference
that you are making to it?
in the book, people have to do 2 years of "federal service" before they get voting rights
"federal service" could be being a nurse or in the military - whatever
SWPLinux: But did they have a fscked up voting system?
the idea was that until you put aside your own greed and self-interest, you're probably unqualified to make decisions that affect everyone
so you have to do it for 2 years if you want to vote
and i think that's terrible.
SWPLinux: Hey, isn't that an oxymoron (politions)
you can choose not to, but then you don't get to vote and you just have to live with whatever the full citizens decide
yeah, and i think that's not the right way to go.
yeah. I don't like it, but it does have its merits
i think there should be free beer for everyone
PARTY AT FENN'S HOUSE!
note that volunteering to do IT work or machine repair for some community organization would also be considered "community service"
it doesn't have to be "some politician telling you what to do"
the compulsory part is what bothers me.
the assumption that people don't want to help unless they're told
i think speaks volumes about the people who support it
and what they think about other people.
no, actually I think the idea is that a lot of people want to help in some way, but the groups that need the help are underfunded
so the idea is to fund them
fund the crap out of them.
but don't make it mandatory, in any way.
give people the oppertunity to show that they're good people, don't tell them "help your fellow man or else."
we'll see how mandatory it ends up being, I'm not too worried about it at the moment
that's the only part i'm worried about.
if he wants to pump funding into volunteer programs, do it.
try to remember this conversation in a couple of years, we'll see what happens :)
haha, i will, and it will be nice to be wrong
I disagree ;)
I'm saying I'll be happy to be wrong
(from my point of view, it wouldn't be nice to be wrong ;) )
I agree, it would be nice if you're wrong
yeah, it will be bad if you are wrong

question: "Several letters (I, J, K, L, P, R) may have different meanings ..." -- there is no L though?
[04:59:57] <ewilhelm> http://www.linuxcnc.org/docview/html//gcode_main.html
hmm, it is missing from the table
I believe L is used with G10, all the canned cycles, and G76
ah, indeed: http://www.isd.mel.nist.gov/personnel/kramer/pubs/RS274NGC_3.web/RS274NGC_33a.html
also, E and O are used but not in that table
all letters are now used
oh? is that being defined somewhere that I'm missing?
[05:06:30] <cradek> http://www.linuxcnc.org/docs/2.2/html/gcode_main.html#cha:O-Codes
this is my favorite docs page. it is a great summary and the links go to the detailed help for each gcode: http://www.linuxcnc.org/docs/2.2/html/gcode.html
to get good cad for linux, i used vmware on last laptop.
i just got new laptop and installed from hardy-emc live cd.
now have error installing vmware server 2 for linux on ubuntu8.04.
err was gcc4.2.4 was installed but gcc4.2.3 was used to build system.
re-installing gcc 4.2.3-1ubuntu3 still had gcc symlinked to gcc4.2.4. any ideas? ignore warning?
cradek, dunno if this would be a simple mod but with your truetype prog, how about a version to use an engraving bit that goes down the center line and varies depth to set width, would require some path finding foo adding, I can see an immediate application with clock dials, will have a browse for algorithms as soon as I can
archivist: sounds neat, but very hard compared to what it currently does
cradek, I had a quick browse, seems the odd commercial one around (mastercam) will look in my graphic gems books as well later for inspiration
I think you have to inscribe circles and construct paths connecting the centers where the depth is proportional to the diameters
starting from a round shape something like that
I can picture the required path in my head, but I don't know how to calculate it
but from square/points then its tip length going deeper till it meets another path
copy/paste the cutter comp code from EMC ;)
archivist: yes each sharp corner would have a path endpoint
I can see the paths in my head easily
yep, me too
SWPLinux: it's a completely different problem from that
imagine wanting to cut out a square. you have a V shaped cutter. you can make an X shape starting at the corners with depth zero, and at the center you have a depth where the diameter equals a side of the square
so with two "V" cuts you've cut out all of the square - the center will be the deepest
you can do this for arbitrary shapes
really fancy engraving becomes possible
do you see it? it's easy to picture/draw, but hard to describe
yes, I see the idea for simple shapes
trying to think about more complex ones
a circle becomes a Z plunge only (assuming the cutter is wide enough)
thin to thick back to thin as in caligraphy
in general you'll have a path starting at each point, going towards the "center" of the shape, getting deeper until it reaches some inscribed maximum diameter
you need something closer to offs
since it has infinite lookahead
yes you need to consider the whole shape at once
(I know it's a path generating tool, but I think the concept is similar)
fortunately the shapes are closed finite-length paths
so the simplest case is just assuming an infinite cutter size and varying depth to set path width
then you need to deal with the reality of having a cutter that's finite width and a maximum desired depth
yes but first attempt make plate thick enough
the CGAL 'skeleton' algorithm does something like this
I have a suspicion that it's these red paths from the black polygons: http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Straight_skeleton_2/Chapter_main.html#ComplexSLS
and use a big cutter
fenn: yeah exactly
too bad about CGAL's license
jepler: I agree those are the paths
also i remember reading that it was easier to do this with pixel based methods
yeah, there's also a relationship to gimp's shaped gradients
the color in the gradient giving depth, and the paths being something related to locally maximal pixels
I think offs will generate those paths, if you add lines from the original cusps to the offset cusps
SWPLinux: except for how offs is unfixably buggy
* jepler has given up on that project
the skeleton should be the same as Held's voronoi diagram
what remains wrong with offs?
cradek: it does not get all self-intersecting offset paths right, it only gets simple cases right.
and I never even got to islands
yeah - seeing that the offset path goes the "wrong direction" is a lot easier than writing a program to detect it
in this example, the upper middle area doesn't fill. the reason has to do with how the offset path has fallen apart, and offs doesn't find that there are parts of the fallen-apart path that it should still work on: http://emergent.unpy.net/files/sandbox/offs-one-more-bug-fixed.png
this is exactly the kind of "it gets very nonlocal" problem that all the papers cite when they say you should use these skeleton algorithms instead of directly offsetting.. but I wouldn't listen to them
but that looks SO close
yes, I know
feel free to fix it
source code is online: http://git.unpy.net/view?p=offs.git;a=summary
bah work getting in the way
"For a similar problem, which (I believe) formalizes what makes constructing the straight skeleton hard, see "Crashing Motorcycles Efficiently". "
it's even hard for a square
consider a 1" square, but offsetting by 2"
(or anything more than 1/2" really)
that's "easy": the signed area of the offset polygon becomes negative
(what, you didn't know that polygon area is signed?)
I was thinking of how to determine the starting position
of the offset path
oh, I thought you were talking about when the inset path becomes degenerate
assuming we start at (0,0) and move to (1,0), the offset path would start at 0,2 and go to 1,2
sure, that's a problem too
offs assumes you can start anywhere on the offset contour
you need to take into account the other connecting segment (in the case of a square, the last segment)
to put it another way, offs takes a closed path and turns it into a set of closed paths
it doesn't deal in starting points
right, the assumption (requirement) is that you always have two segments at each point
which isn't true for the actual source path, until you look at the entire thing

I bet I know the ending price
$0, $1000, or $2500 :)
well, if you buy it
looks like a 4 position turret, but it's long enough to put several tools on each side
yeah, a lot of screws on that plate
but drills and boring bars, I dunno.
I wonder if they're right that it repeats to 50 millionths
so many toys to get so little money and space
yeah, there's the rub
that means a tenth on diameter? if it's the same class as mine, possibly
don't breathe on the part before you measure it though
or breathe a lot while it's being machined ;)
just keep the coolant at 98.6 degrees so you can measure easier
make it work it will warm itself up
it looks pretty clean, and if it works as a CNC now, the retrofit should be easier
oh hmm, I guess I should check out soon
it has a crt - the control might be quite usable as-is
as long as I can get the "verbage" to come out right ;)
maybe Stuart would want the screen for one of his machines ;)
looks like its done little work
dang it is in New York
yeah, I don't know if they described everything, but skimming .007 off Aluminum for decades doesn't sound too hard
If it was closer I'd buy it
me too (still might :) )
I got my mill in Buffalo
it's about 18 hours to Buffalo from here :(
bummer. only ~8 from here
where are you? I thought you were in the northeast somewhere
ship from here :(((
driving a lathe for 8 hours is quite possible
I'm in swamp east Missouri
get a few friends together and it's almost fun
yeah, we picked up my mill then a Takisawa lathe in the same run
I'd go 12 hours
ah, ok then
BigJohnT: an 8 hour drive takes 12 hours at 50mph :-)
silly speed limits over there :)
yep with 4000 lbs on your trailer...
it's not the law, it's just a good idea
when the trailer weighs 50% more than the tow vehicle
I got my manual lathe from Dallas it was a long trip back
KE ~ m*v^2
so V~= swrt(2) * normal_V
for the same Ke
google says it is only 14 hours
I just can't seem to find the specs on the machine
like spindle HP
looks like it's a 6 or 8" chuck
I bet it has 18" of Z travel or less
with no provision for a tailstock, more length is useless
would be nice to know the spindle bore size, and if it can take collets
[15:44:21] <cradek> http://img.photobucket.com/albums/v618/Chevy427z/toolturretandcolletnose.jpg
oh yeah, forgot to ask that
might be 5C, but it looks suspiciously small
others I've seen via google are 16c ...
so it's hard to tell
it's 16c with a tailstock and about 7" swing over the ways
oh so the turret goes in front of the work, not beside it?
do they have back gear, or just designed for light work
can't tell from the Q&A's at the bottom of the page
I love paying bills with Iron Man playing in the background :)
oh - I guess I could have read those Q/As :)
that many q's shows interest
some from Europe though, which probably won't matter due to shipping/crating costs

emc will optimize this gcodes in G64P0.01 mode ?
my recollection is that emc will exact-stop at an M3/M4/M5 regardless of the path control mode, but I don't know for certain.
yes, and possibly also M50
but definitely M4/M5
so there is no way to change IO during move without stopping ?
I don't think so
oh well off to the fab shop... talk to you guys later
this guy's cam software requires that there be a sound device to run !?
heh I saw that

i also enjoy cleaning with fire
hy everbody, i am planing to tune up my CNC to a fabber, i know someone has done it before but i have some differnet ideas for the extruder. There for i need information wether there is a pin which i can use to differ between G0 or G1/2 movements. does it exist ?
why not just program a Mxxx to turn off the extruder before you do rapids?
sorry for my english ! :-) out off training
I want to use a Stepper for the Extruder in a Kinematic so that i can use ramps and other things. that is what im missing in repraps at this time.
I think you can get much more precision an eventualy speed, if you are able to run the program with ramps, and the other thing is to leave the g-code unchanged as possible
by the way, is alex online sometimes ?
are you talking some sort of feed rate override?
seems to want to program acceleration rate
i want to drive a Extruder as a Stepper . running only when G1/G2 operations are executed , in a defind speedrate to the XY movements
( endless in one direktion )
what do you mean "ramps"?
emc does that automatically
i think you should just couple spindle speed to your stepper in HAL somehow
then, if it really matters, you could do a spindle-synchronized move when extruding
or maybe i'm thinking adaptive feed
yah, i am searching for a pin that differs between G0 and G1 movements.
there is no pin
you can turn certain pins on and off with other g-codes though, and put those before/after any g0 move
you could probably turn a pin on above a certain velocity..
hmm is there a way to make the spindle slow down in response to feed override?
is that just a scale block in hal?
sorry computer shutdown
Can any one tell me, How fast is, Stepper Step can run on EMC2 ?
...The fastest Step Clock...
is it 80k step / sec ?
cos maybe different kind of stepper could result different strength...
Fisia: you should be able to do 30k easilly
big one and small one... or other...
depending on your system, that is
is it 30K is the fastest EMC2 able to?
depends on your computer how fast EMC can do it reliably
Fisia: it depends on the computer and stepper driver timing requirements
the 30k is for a computer that has 11uS latency, iirc
more than 30k is not necessary in my opinion
I want to run the extruder in a exact follow off the XY Axis (example : X moves 3 mm / Extruder has to make 12 steps ) only while G1 / G2 moves and with the same accelerations !
can u specify kind of computer like xxGHz Processor
fenn... explain why please..
plattschnauze_: emc has a "constant surface speed" mode which might work for that, typically used for facing cuts on lathes
plattschnauze_: but the "only while g1" isn't going to happen, sorry.
<plattschnauze_> u can use 2 computer ?
at a time..
Fisia: or http://wiki.linuxcnc.org/uploads/StepTimingCalculatorPlus.ods
Fisia: if you need more speed, decrease the number of microsteps in your stepper driver. if you need high speed and high resolution, you should probably be using servo motors anyway
I can use 5 computers at a time , if i want, but that was an accident :-)
Fisia: basically it's because step/dir is a crappy interface
ok... ill go there, Thxs ! :)
sometimes i ssh from one computer to another and back, does that count?
fenn, step/dir is a crappy interface, what does it mean, explain please..
Fisia: step/dir is one signal line is for taking one step on the stepper motor, and the dir is the line that tells the controller what direction to step in
Fisia: it takes a long time to tell the motor to hurry up and move, because you have to send a pulse for each micron
but each pulse has to come at exactly the right time
fenn: don't you have to send the information at the exact right time.. nomatter the interface? ;p
step and dir is a nice hack for nice steppers..
but with servos you can react to error
if you want a better/nicer/faster/more accurate machine use servos..
I'm not arguing that
steppers have big tradeoff between accuracy/speed/torque
yes, true... but i still have kind of interrest on stepper control ...since PC has a 'little' changes
Fisia: then you are stuck with the limitations of steppers
there's also hardware step generators like jon elsons boards
well, that wont cange that when you try to go fast steppers suck
true... but still interresting for hurry machines
stepper weak on precision, speed, ... all u name it cos its a true open loop archivist says
but all in emc2 is important knowledge for me
including stepper dinosaur
anonimasu: my issue with hardware step generators is that they're basically a servo interface
price-wise, steppers aren't that bad, drivers can be made on the cheap too, and for most homemade stuff, they are more accurate than the machine itself :p
fenn: yeah, but the motor's still a stepper
ideally you'd just run the stepper as an AC servo
:) true... still enteresting, yeah
fenn: isn't that basically what microstepping is?
fragalot: sorta, but you have this silly step/dir interface to deal with
I can live with that
can stepper (big one/strength one) do 50k steps/sec ...(i go check site u reffer to)
and no feedback, and nothing to do with the feedback if you had it
larger steppers have lower top useful speeds
makes it easier to hook up alternative interfaces,.. like you could hook up a pulse generator and it'd work
for me, .. I don't care about speed, all i'll use it for is PCB's anyways,.. :p
me, i dont really care about pulse generators
btw. other day (at night day) i ask about RTAI that only active when G-Code being execute and CNC really goes running, how about it?
any comment please...
rephrase that in a question please
I think you need to download and start looking at the sourcecode of emc
at that time all GUI-luxury and Multitasking being freeze to image HDD memmory swap,
* archivist frezes, cant digest that sentence
can RTAI only be activated on 'only certain time' like when G-code being execute
other time, RTAI can being turn off
did you try emc yet?
it's like that now, except that RTAI is activated when you start EMC
yes... it is fast already
and deactivated when you close EMC
i know that just now.
(it is like EMC2 reads all my mind, all i ve thinkin just already happen)
Yes, that is why the economy is shot.
i opening hall as a home work, stepper is my first learning object... :)
can anyone help ? got an cnc
a chinese one
if you have some specific questions, we can try to answer them
ok, sorry here it is
anyone knows anthing about scraping?
think making scrapers out of a old file would work?
err a scraper
anonimasu: I think that's what some people do, yes
:) ? (i still not understand the question)
anonimasu, yes or braze lump of hss on something
one of my ex bosses bought a cnc directly from china a cte1225s, couple months later had a car crash and is gone (: now i'm trying to discover the machine
I'd be tempted to try mounting a carbide insert to the end of something long
i'm asking here because i'm a linux user
sorry to hear about your boss. what is the question?
for the moment ain't got no docs and don't know where to start
got a name of the machine?
I'd call up the representative of that company in your country
is the mill controlled by emc2 now? or it's controlled by something else, and you want to make emc the controller?
i think u might use ebay for a start.. :)
yes ofc CTE1225S
then call the reseller.
google says its a cnc engraver
they don't even knoew a few words in english u may check their site, even the manual i found (which is few pages) is in a poor english
are you thinking of a retrofit
I found this page which implies that it uses a proprietary PCI card to communicate with the machine: http://www.fuzing.com/vli/001995204216/CNC-cutting-and-engraving-machine-CTE1225
do ou know anything about cnc machines or g-code or anything?
whatever this pci card is, it's unlikely it works with emc
partyzun: do you know anything about cnc machines?
haven't tested though on other pc
unless you can obtain programming information for this pci card, and are willing to write the emc driver or pay someone to do it, it won't work
partyzun: isnt there already software from the manufacturer to operate the machine?
now is runin on a dell with win2k and the vga card is defective so the image is a little unclear
anonimasu: there is just a soft delivered with the machine named creation
well, I'd suggest playing around with it, until you get familiar
it says the system uses stepper motors. if the stepper motors use standard "step & direction" signals, then you can throw away the PCI card and use one of emc's stepper interfaces such as the parallel port, pico-systems, or mesa
u can use EMC2 with mesa
jepler is right, that would do.
another states 700watts on the axis
could be servo on some models
still the same dir/step inside
I might be tempted to retrofit
congratulation, your fun emc2 adventure just to begin. :)
the first step is to gather much more information about the machine.
low cost u get
but it is deppent just like car-modify
but it would run for sure, once u fix it
anon... what mat'l are you scrapping???
I get alot of knowledge in just because 'iam' here... it is true,
it is my honour
i have to log off now
'The stepper controller requires a minimum step pulse width (typically 1µs).' i rellly got almost whole my answer here u see, Alot of thanks to you all
anonimasu: cradek jepler thanks guys for your kindness hope to be back with good news
partyzun: I'd try the stock program first and see if I could decipher it, then go on as to how to make it run
have fun partyzun
I'd think it's better to make parts ten spending time figuring out how to retrofit it with emc or something else
err damn keyb.
good point i'll try
a machine that wont run is a money sink
i woke in the middle of this with no intention but at least want to continue
nice to have you around thanks again and keep in touch
well damn. lathes.co.uk says this about the HXL "In 1983 the company launched its first CNC machine, the Model HXL; although originally designed as a CNC toolroom lathe it was marketed as a production machine and, with a weak turret and cantankerous GE1050 control system, was destined not to be a success."
weak turret doesn't sound good - I wonder what specifically they mean by that
it looks weak in that it only holds 4 tools, and it has 100 bolts you have to tighten (so repeatability/alignment may suck)
if it's weak as in "you can't take heavy cuts", that's a totally different problem
perhaps written by a machine abuser
lathes.co.uk is ueually pretty good (I think)
[20:37:43] <SWPadnos> http://www.lathes.co.uk/cataract/page23.html
surely the bottom of the turret will be a certain distance below the spindle centerline, so tools of a certain height are automatically aligned
"Page Title" heh
yeah, a lot of them are liek that ;)
he is not far from us
AHHHH you posted those letters "GE1050" FLASHBACK... :0
dmess, do you know about the Hardinge HXL?
have met the person who runs the site
the other practical problem is that I only have an 83" high garage door ;)
large hammer should sort the door
or a couple of small ones, then some replacement nails
thinking about light cuts, was getting belt slip here today :) and only 30thou wide cut 4 thou feed
no freecutting steel
old machines just not built for a good meaty cut
well depends on speeds and feeds and material, have had swarf over the tailstock on the same machine
SWPadnos: "A rocket engine is a jet engine that uses only propellant mass for forming its high speed propulsive jet. " [wikipedia]
* fragalot wants a solar hydrocar toy
nearly Xmas :o
SWPadnos: it might also be a starting system..
hmmm. could be
for jet engines, rockets you just light up
turbine jet engines need a starter. I'm not sure about other types
I think they all do
ah - an intake
for the liquid (also includes gases) propellant
so my answer was nearly correct - the propellant is carried by a rocket, but it's not for any other type of jet
jet engines are lovely
some types don't even have any moving parts
SWPadnos: isn't this something your mom would know?

skunkworks_, no, she wouldn't know anything that has to do wit (gasp) engineering!
my grandma is a wiz in engineering... you should see her knit socks.... shes a machine
isn't that manufacturing
Got a question about EMC2
(or slave labor, one of the two)
she had to figure out the needle things
engineering is the sock coming out the right size
markdashabout, woohoo! an EMC2 question. shoot :)
[21:56:35] <jymm> http://emc.com/2
I am trying to run it with my sherline mill and Ive even seen people suggest that there is a shereline option to select from the config screen
but I dont have it.
Is there? And if not, how can there not be?
it is her labour of love.. at 88 yrs old she still makes 4 pair of new wool socks every fall / thanksgiving
markdashabout, its in the stepconf program
in stepconf, there are sherline presets to make it easy to build a configuration for a sherline
I have heard that one or more of the timings is wrong, however
well, the sherline button in stepconf (the config program) only sets the step pulse timing and which pins are step/direction
markdashabout, but I saw a comment about a bug with it anyway
for the last part of your question: there could not be, since sherline has not given us this information.
Yes, I heard that, too and that doesnt seem like a problem.
it does not make a complete config for your sherline - you still need to know things like pulley ratios, screw pitch, travel limits, etc.
markdashabout, first off, are you talking about stepconf when you say
"the config screen" ?
No, I fired up emc2 with the emc command and have a list of (I think) .ini files ona gui.
There are thousands of these tiny table top mills around I suppose and it seems odd that I should need to configure?
I am nervous that if I run stepconf it will not be as good as my pre-configured emc1 configuration.
markdashabout: I agree, it would be nice if sherline would contribute configurations for the machines they are currently selling; we would be happy to host and distribute them with emc2 releases.
if you recently bought a new sherline machine, you are in a position to let them know that it is important to you.
Would it be possible to parse info out of an emc1 config or is it very very different?
it is quite different
Yeah, thought it would be, wouldnt be much point in writing emc2 if it was basicically the same now would there !!!
we (like you) are disappointed that they ship such very old EMC software
but of course, that is up to them.
It must be said that the EMC1 machine works very well, what really hacks me off is the linux is so old that even getting a network to work is a challenge.
I'm not sure if there's still any development going on for that version of EMC
I have not seen any for a few years? now
there were a couple of developers who were maintaining it, but I don't know their current level of involvement
But I am sure I have seen people say just select it from the menu, I even got the name of the file Sherlinemill.ini, but of course anyone could make that up.
but EMC2 is very active
No , no development. I want emc2 anyway!
go ahead and work through the stepconf wizard, and let us know if you have any questions.
huh, there it is: http://www.linuxcnc.org/docs/2.1/html/common/emc2_introduction/emc2_introduction.html
(references to Sherlinemill.ini)
Alright I'll do that, if thats what people do.
the sherline timing preset is wrong in the current version of emc 2.2
but it doesn't say they exist, it only says that they're more descriptive names than "generic"
in stepconf, that is
But its really odd. SL ought to help us and the emc people here, after all they do make a lot of use of emc1
There are a lot of these inexpensive mills around after all, and at least some of them must be the same???!!
they should probably start using EMC2
nope, they're almost all different in the little details
some user reported that by switching the "step length" and "step space" values shown he got a working configuration, but I'm not sure that matches the step timings emc1 gave for sherline
mine is red :D
some use Xylotex drives, otehrs Geckos, others custom (like Sherline)
the travel limits are different, some people have home switches and others don't ...
Well of course if nobody does then that would explain it.
I'm just going to look at the url you sent... (pause)...
no don't, that's extremely outdated
it's an old manual for EMC2 2.1
just work through the stepconf wizard.
SWPadnos: is that doc reference still in the current docs? if so, I'll drop bigjohnt a message to fix it
google didn't find it in later versions (at least not a tthe top of the list)
markdashabout: sherline used to be very active in the emc community; recently, they aren't.
redirect the web page to current docs and make old docs download only
archivist, well, that's one way, but people using 2.1 should still have docs available for that version
thats why I say download
Trouble is, do you think I'll get a workable config out of stepconfig. I mean one that makes circles circular and the right size??
markdashabout: if you answer the questions correctly, yes
yes, if you know what your machine is
markdashabout: if you get it wrong, then you fix it
as long as you don't edit something manually, you can load the config back into stepconf and fix things
loop a couple or three times, save setups as different versions if you wish
So if I try step conf, do you think I'll get a machine that produces repeatable results,
I already answered that: 'if you answer the questions correctly, yes'
you'll get repeatable results with either config :D
again, that's only if you can answer the questions correctly
I used stepconf for my machine
if you answer the questions correctly you'll get good repeatable results
but, there is a problem with the Sherline timings - hold on a sec
Sorry asked same question twice thought client had crashed!!!
Ok will go and try it!
Thanks for your help guys!
Ok will hold ok !!
welcome, hope you get it going.
markdashabout: you don't need to close the IRC chat just to configure emc2 :)
(unless they are on different PC's)
hmmm - I don't see the fix I'm looking for
Ok, I was waiting to see what SWPadnos was going to say, he said hold on so I'm holding....
markdashabout: here's the person who says the stepconf timings are wrong and gives a fix: http://www.cnczone.com/forums/showpost.php?p=432441&postcount=10
It is on a different machine but one of the joys of modern X is I can have the display here and run it there...
but the bottom line is when you choose the "sherline" driver timings line, you get wrong numbers that may not work reliably
(this is my fault, I wrote stepconf and didn't find the right numbers to put in)
oh hey - that's the information I was looking for (but I thought it was changed in stepconf)
SWPadnos: it's been changed but not in a released version
jepler: not your fault that the timing are obscure/hidden
I was looking at commit messages
Oh, wow, well I am honoured to be talking to the king!
markdashabout: no kings here -- just a bunch of citizens
markdashabout: all kings around here, and a couple of queens like SWPadnos
* alex_joni blushes
I like Queen
well, that queen eats lie a pig!
alex_joni: uhhhhh maybe there's something you need to know about Steve...
jepler: I prefer not knowing :P
it's the long hair - gets 'em every time
markdashabout: we also are a really happy/crazy bunch in here
proof that alex_joni is in de nile
don't take it all too serious
nothing wrong with being a hairy
jymm: your jokes would be lots more appreciated if you would spell them right :P
alex_joni: Learn to speak typo =)
I think that was a double joke
it's all good, I just want to get out of here and start the weekend
dont care about anything else
ooh, time to get out of the office
see all you guys around
see you jymm
and jeff ;)
for me its time to stay at work and do MY jobs
archivist: should be 8pm there.. ?
my math is terrible.. 00:30 here
might get another 1/2" of steel converted to swarf
Haha!! I missed all that looking at stepconf. Seems like it knows quite a lot about sherline...
I have swaped the two parameters round in the file it generated...
Am trying to test but get messages like
joint 0 on limit switch error
Of course, there are no limit switches!!
markdashabout: rerun stepconf, and disable the limit switches
markdashabout: on the pinout page, change all the inputs to "not connected" or "unused" or whatever it says
* alex_joni is off to bed
good night all
Thanks jepler, yes thats what I figured and that overcame that problem. But current problem is to try to figure out what the pralell pin connections actuallya
actually are, because the two pre-config options (sherline, xysomething) neither seem to work.
(There is info for a hand-controller on the sherline page that gives connections same as non-sherline connections on stepconf)
alex_joni: Yep you're right, your math is really off, it's 2:30pm, not 00:30 =) 02:26:32 PM) alex_joni: my math is terrible.. 00:30 here
