I bet a laser could be used
No, I touch-off there the same. Normally I just park the tool tip to the right of the work and measure the gap with the calipers.
You could use a G38 probe command and a touch sensor tool.
yea thats what I wanna build
I thik (though I haven't tried it) that you could write a custom G-code that combined a G38 probe with a G10 L2 P(whatever) to do it all automagically.
I can sure snap bits tho
Well, I did that this evening.
what is your mill andy a lathe?
[00:05:46] <andypugh> http://www.youtube.com/user/blyndpew#p/a/u/1/95B8PDlnajk
thats so kool
If I was doing it again I would start with something higher-quality and second-hand
did you build it all?
No, I bought most of it.
It was a manual combination machine that I retrofitted for CNC
I wish Peter was here
hello: I'm trying to run latency test using the linuxcnc 8.04 live cd (not installing) and get the attached error message: (is there any way to make emc2 work on my hardware?)
ok that explains the accuracy
[00:12:24] <andypugh> http://www.amadeal.co.uk/acatalog/CX23A-750_Multi-Purpose_Lathe_Milling_Machine.html
Is the original manual machine
(Though I paid a fair deal less than that)
I havnt found a cross slide vise worth buying yet
and I was thinking of doing just what youve done
looking for an older mill
maybe a bridgeport
I bought quite a nice one on eBay, but find myself mainly using that rather nasty one in the video. (Though it is much improved with a better retaining plate and a bit of judicous slide-scraping)
old bridgeport cnc :)
what RPM is the spindle running at?
like archivist_emc said get the goodies with your mill
you might get better tracking if you take the handle off the spindle drive too
In the video? Probably too slow for the drill bits, and the feed could have been a lot quicker too.
I tried removing the handles and it made no difference (except that I then couldn't move them by hand)
guest use a pastebin
Guest746: You can paste your error message there and then we can see it. Pasting more than a few lines here directly gets you booted by the server.
<param name="nick" value="anleu1??"
hello everyone, I tried installing 8.04 with emc2 from the linuxcnc live cd; but cannot get emc to run.
Can you get it to run if booted from the CD?
define "cannot get emc to run"
when using the cd as live cd, i run latency-test from the terminal I get the following error list http://pastebin.ca/1655751
is there any way to get emc running with my hardware configuration?
axis runs better on my geforce than my ati
Guest746: Booting off the CD it really ought to Just Work
that looks like you're not running the realtime kernel
I mean I get error messages when I try runningn emc2 from the menu; I can paste that error list too
You will get errors, you are not running the right kernel
Boot from CD and it should work
how can I fix that? i tough the live cd had the right kernel!
so you just booted it with all the default settings?
I booted from the cd
What does uname -r say?
(I think that is the command to list the kernel version)
I had to change hard drives and boot into windows to enter this; but I'm writing this now
You should be able to IRC from inside Ubuntu
I get a random case of keyboard quiting on me, thats another issue
so andypugh, you mean typing "myname -r"?
Actually, you probably have got the right kernel, but the realtime kernel modules are not loading
No, the command is "uname -r"
on system monitor it shows the kernel as "2.6.24-16 rtai"
OK, that is correct
I think the problem is the segmentation fault when it tries to load the kernel module
I guess rtai is not compatible with my hardware then?
What is your hardware?
athlon 64 3500+, 1gig pc3200 ram, ide drives, ps2 keyboard/mouse, nvidia geforce 5500, soundblaster pci card, generic pci modem board
type "dmesg" in a terminal
it should give some related info somewhere at the bottom
i will once I get back to linux, what should I look for?
[00:47:03] <andypugh> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Nvidia_Card_configuration_issues
not so trivial when using the live-cd, though
Yeah, I wouldn't have thought that they would put an incompatible driver on the Live-CD
ok, thanks a lot for your help! I will change drives and try your suggestions
you have to replace it in the file, and after that, restart the X server and after that unload the nvidia module... i guess
which is "rmmod nvidia"
and the X server should restart with ctrl+alt+backspace
if not, umm... well, it probably will
well, it depends if it's configured to restart automatically
also, some version of ubuntu has ctrl+alt+backspace disabled
if u get dropped to cmd
which means you'll have to kill it with "sudo killall Xorg" or something
the other way to do it is to just install it on the hd and then doing what the page says (and rebooting the machine after that)
I tried it on my liveCD installed VM and ctrl-alt-backspace restarted it.
theres a few nvidia setup tools
celeron55 its later than that
would that explain the problem I have with the keyboard quittin suddenly?
I used envy in the past
Right, the day I find myself trying to give linux advice is the day I am up too late. Goodnight.
thanks a lot!!
so 1) edit 'Driver "nvidia"' to 'Driver "nv"' in /etc/X11/xorg.conf (as super-user), 2) ctrl+alt+backspace, 3) sudo rmmod nvidia
make sure it runs glxgears
well, vesa will always work but is slow, nv is faster and works 99% of time :P
I wonder if he would be better served dropping to a console then modprobing rtai
he could at least see the fault then if is causing a panic of some kind
the nvidia binary driver typically causes latency spikes not non functional machines
don't ever get foam in a can on your fingers.
its not a good idea
I will try all of this and get back to this channel with a report
how do I get a name and not "Guest746"?
see if you can get on here from there
type /nick foo
skunkworks: when sealing around door frames, dont get it in your hair!
eww - you win
I had to puncture the side of the can to get it to come out. hard getting the hole 'just right'
don't try this at home.
no, you win
lol that is not cool
<skunkworks> I had to puncture the side of the can to get it to come out. hard getting the hole 'just right'...you might be a red if..
well those stupid cans stop working if they are old - even though they have never been used.
i have a 30 gallon kiln based around this entire princible
I wanna try used cooking oil
french fried raku
I melt alum in it
fenn does green casting, he's on here sometimes
ive done lost wax, but thats tiny stuff
how is the kiln based on punctured foam cans?
Im just makin bars and 1x4x16
30 gallon trashcan
its fired by a puntured gas line
pushed thru a short piece of tailpipe
trashcan and tail pipe stand up to temps that melt alum?
with 5 inches of mudliner
perlite vermiculite and bentonite about 25 bucs at the nursery
MarkusBec is now known as MarkusBec_away
oh and some portland too, mix well..
melts lawnmowers chainsaws that old lawn furnature from the 70's
lighting is a lil tricky ..blows the lid off if you get too much charge
fun at partys..0o
>>>its fired by a punctured gas line
You're neighbors?? ;-)
bbq regulator with short piece of 3/8 copper line crimped and puntured
first attempt failed to get the hole right...lmao
I use an old hair drier pointed up the tailpipe to charge
dont try this at home folks
exploding 2000+ degree furnace liner is no joke
now if I could control the foundry ops with emc that would be keen
follow a part from cast to lathe
or even better use the melt in a feedline to
Bluntz_: i would like that as well
pour a part up
for this reason i've been working on this project:
[02:28:53] <kanzure> http://adl.serveftp.org/dokuwiki/skdb
not quite for "following" but rather generating the steps from cast to lathe and then some
(practically the same thing if you're starting fresh)
a molten metal printhead wood be problematic for sure
ok how do I install it?
Bluntz_: are you on linux?
the main dependency of skdb is pythonocc, we have detailed instructions here: http://adl.serveftp.org/dokuwiki/pythonocc
soon we will have a .deb or .egg or something but right now i'm willing to walk you through if you have any difficulties
kanzure: is there an example widget that is specified/detailed/fulfilled by this system?
tom3p: screws: http://adl.serveftp.org/skdb/packages/screw/
if anyone knows how to make a helix in opencascade we can add parametric CAD models for screws but as it is OCC's helix function doesn't work
making skdb dependent on OCC might have been a mistake :)
1.5 gb build
i have this strong urge to just yank it out and write my own cad kernel.. but i know this will take a long time, and i am too eager
Bluntz_: yeah pythonocc uses swig to generate all sorts of wrappers to occ. i think this is what takes up the bulk of that space. possibly also occ source code and other things that can be deleted.
git clone git://adl.serveftp.org/skdb.git skdb ???
its a rather big investment for a beta
Bluntz_: skdb works without opencascade installed i think
tom3p holds nose & jumps in
tom3p: if that doesn't work try git clone http://adl.serveftp.org/skdb.git
* kanzure doesn't remember if he configured the git protocol or not
rats, this box aint got no git, installing that 1st
does anyone here have any ISO, ASME, ASMUG, etc. standards/specs of machine elements? this would be immensely helpful
i can't get a hold of ISO 10303-214 as it is, much less anyhing more useful than the machinery's handbook
i'm not clear on the idea, but you're certainly touching the ideas of some technologyforthepeople groups and openmanufacturingflow stuff
if you're on ubuntu, and you use apt-get, then you basically have the idea down.
except i want to "apt-get" myself some hardware and have it show up in the shop
yeh thats the xfer tool, but the knowledge base and its application isnt clear yet
either through my physical excersions or others
*others (like machines)
well the application is figuring out how to build things
when you start a project you're always wondering if you have this or that, or how you can approach doing x
different routes for building the same thing. etc.
well wherte does this come in... its easiest to make round metal stuff... where does 'smart' or 'craftsman' enter this?
kids playinmg with cad, create stuff that cannot be built
yeah that happens all the time
so fenn put some thought into this.. i don't know why he's not in here
they need some leadership/tutor/journeyman
[03:01:31] <kanzure> http://adl.serveftp.org/skdb/processes.yaml
yes i agree
but one idea in the mean time is to make a representation of what a machine can manufacture
for instance, a band saw cannot be operated at 90 degrees
good stuff, im interested
also, bits have wear and tear
ideally you should ask what you can build with your hardware already... but people want to randomly make stuff too
like kids with their cad models
soo the idea is to maybe use the "representation" of what you can manufacture
and then see if you can get it close to what the input is
if so, then you have a recipe/build-plan for making that part
using only what you already have
i was surprised by a post earlier from cradek, some buyblueprints site, it had plans for some mechanisms and jigs.
this representation of what a machine can manufacture has been started in that processes.yaml file but there's more work to be done
yaml is... yet another ???
* kanzure nods.
ok some xml ish
it's a simple language meant for human readability
also meant for humans to edit by hand if they wanted to
so just press enter and add a '?' or '-' to start a new item in a list, or do something else, etc.
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-11-04.txt

whoa quite a few files
[03:17:38] <skunkworks> http://pastebin.ca/1655943
I find the last part very hard to believe. sounds like xp would work better than linux ;)
it might, under the right circumstances
if it lets you more or less turn off multitasking, then it should be possible to make it work very well for your task
It is more likely that the os 'is' just the gui and motion is done on the external hardware.
seems that way
atleast more beleivable
oh well - time for bed. Night
kanzure: python ./packages/lego/demo.py ... ImportError: No module named skdb
forget to switch the clocks back? :)
early day.. :)
tom3p: you need to do something like this: export PYTHONPATH=$PYTHONPATH:/home/tomp/
if skdb is still in /home/tomp/
almost gave away my alt nick
was *this close* saying what kanzure just said :)
oh please, we all know it's akafubu
last time i give you ssh access to the puters ;)
it's the first nick i whois'd and you're in all the channels i'm in, so i figured it's you
tom3p: that help?
kanzure: export PYTHONPATH=$PYTHONPATH:/home/tomp/skdb/core python ./packages/lego/demo.py ImportError: No module named yaml are there more deps?
tom3p: yes, sorry. sudo apt-get install python-yaml
hm.. why don't we have a list of dependencies.
yaml aint a package as far as apt-get thinks
sudo easy_install pyyaml
yeah, after sudo apt-get install easy-install maybe
i kinda assumed it came with python
also you'll need python-igraph or python-cgraph. i forget which one it's called.
god this sucks. i'm so sorry
easy-install isnt a pkg either... np, i'll just watch the site, the packaging will get sorted
it's python setuptools
apt-cache search setuptool
anyway, yeah, btw i can be motivated to fix all this faster if you yell at me about this on a frequent basis :p
i thought i had written down python-yaml somewhere as a dep.
hahah i installed all those suggested, by apt-cache search, and easy-install aint in there, sorry, im buggerin up my system, gonna clean it before i loose track of all the crap thats been gotten
i'll just monitor the site for now
easy_install is in python-setuptools. but anyway, yeah. sorry this didn't work out
it'll be resolved soon :)
python-setuptools is already the newest version easy-install isnt in there
you'll get it
kanzure@pikachu:~$ apt-file search easy_install
version: Version: 0.6c9-2
what about you? version is shown with apt-cache show python-setuptools
hahahaha apt-file not found.... noooooooooooooO!!!! not for me
sudo apt-get install apt-file; sudo apt-file update
already cleaning up, no mas!
apt-file is really really nifty

could I use HAL to basically run a servo loop with python providing the motion targets?
think basically of replacing gcode with some other doovey that'd provide motion targets at ~100-200hz or so
then have HAL try to hit those targets?
or am I way off base
Valen: you can do this but I can't tell you if it will work
I'm thinking of using EMC to drive weird things like telescopes and well other weird things
iirc there was a telescope using enc
Valen, that would work just fine
just import hal in your python program, and make some HAL pins that you'll use to output the positions
that could be handy
the PID blocks (and limiters, if you want to limit accel) would respond exactly as they do now for the motion controller
now I just need to rember the cool thing I wanted to do with it lol
hmm, might go talk to my uni, I could probably swing a PHD out of unfucking their telescope
then i can be Dr Anderson
you're in Australia, right?
let me know if you need an assistant :)
err - co-unfucker
last I heard they had all these super magical encoders and motors etc on it but they had terrible trouble getting it to drive and track
lol where are you again?
only thing is they want squillions in fees to do it
lol so why do you want to come to the sun burnt country? ;->
Winter is starting
plus, I've never been there
it was 40C (104f) here yesterday
and it hasnt really started summer yet
it was 40F here yesterday
and going lower
put a jumper on ;->
maybe I could count it as a medical expense - need more vitamin D :)
hah, last blood test i had said i was defficent
friends of mine have been to USA and say the sun is totally different there
you need to get outside more
like go outside for 2 hours in the middle of the day and you get a light tan
less of a crisping thing, more of a slow bake
oh, isn't the ozone hole over AU somewhere?
I tan pretty easily but i can get burnt in about 15 minutes in the middle of the day
yeah, most of it lol
i have a "dark" complexion usually
I used to tan quite dark (as a kid), but I'm zombie pale these days
so its kinda hard lol, I have been trying to get out more but i don't want to die of skin cancer lol
heh about the same
still i'm getting some colour
its not so bad after 4:00pm ;->
then you just need to worry about the spiders, snakes and drop bears
sure - nothing big
lol was funny, was doing some stuff with a guy in new zeland (probably something like canda > usa to you guys)
that is one thing that you get when your area freezes for a fwe months a year - no big nasty poisonous things around
guys missus wanted to come here but he was freaked by snakes and spiders
its not so bad really
if you leave shoes outside check them
kick shit out of a log before you pick it up
or master the art of the quick flick
snakes arent more afraid of you than you are of them but they wont come after you
I guess we have similar problems, but not as bad. ticks may land on your head and give you Lyme Disease
we get paralisis ticks here too but i don't think we have Lyme Disease yet
got a buttload off the dogs after we went out in the bush once
would have been 100+
actually, we may go to Australia next year - I've got lots of miles and points, so we can fly and stay for free
cool I'll have to show you the shed if you come through sydney
we surely would, since that's the common entry point for United flights :)
ticks, they go after dogs
neither of us got any, (which is surprising considering what we were doing there *cough hack*)
we got probably 80 or so small ticks (i think you call them deer ticks?) off each of them and 10-20 paralysis ticks (the ones that kill you eventually)
yeah, sounds lovely
pretty rare though, i mean i've never been bitten by a spider or anything like that
seen a few snakes
massive red belly black snake on our daily walk once
would have been 5 or 6 feet long
sunning itself on the tar
heh. here, it's "cool" to run across a snake - none of them bite or have venom, so they're cute and interesting
oh it was cool here to, called the dogs back put them on the lead and waited till it went into the bushes
I'm no taxonimist but full marks to the guy who described that one. I've never seen one before but i am damn sure thats what it was ;->
(they are also really really poisonous and somewhat aggressive)
and they only exist in the eastern parts of Australia - nive
(thats only where like 90% of the population is ;->)
what are the temperatures there in July?
depends where you are
say Sydney - I'd expect it to be warmer in Cairns :)
western sydney (where i am) varies somewhat
minimums of around 0C are common
but not for long
-2 - -4 some days
dont do queensland in summer ;->
our summer or yours?
its like 4 billion degrees and 900% humidity
ah, sunny :)
its the humidity thats the problem
its just groady
do QLD in spring
well its good for us in spring anyway
temps are nice, air is cool
humidity is low
sit on the beach eating fish and chips reading a book
I've been thinking of doing an "exotic" trip for Christmas this year, like somewhere in the pacific rim, but Australia could be good too
when it gets to -20C here, my wife starts thinking about warmer climates :)
sydney in mid summer is probably not an ideal change ;->
its sitting in front of the computer with shorts on and not much else with the fan on full blast ;->
but the flight is long enough that we might adjust ;)
its not too bad if your in the city mostly
where i am is 50-70km from the ocean and at the base of the mountains
or hills if your from another country ;->
4400 feet here
(mountains that is)
oh we get close to that I think
I have climed the tallest mountain in australia
ok so i walked up it
huh well waddya know turns out mountains are smaller than i thaught
what's the threshold?
[13:42:54] <Valen> http://en.wikipedia.org/wiki/Mountain
seems to depend on what you feel like calling it
in that case we have mountains dammit
you a diver?
no, but I'd like to be
I've gone on a dive off Grand Turk Island - that was very cool
and the Great Barrier Reef is on my list
i havent done much but the reef is on mine too ;->
I have done some shore dives from merimbula (near where my mum lives) that were nice
my wife has a fear of diving, based on an unfortunate incident when we were snorkeling
ahh sucky :-<
oh, we just went too far out of her confort zone, and I had to help get her back to shore
yeah thats no fun
she wasn't all that confortable breathing with her face in the water in the first place, and that made it worse
if snorkaling isn't her cup of tea scuba probably isnt going to float her boat either
plus there's the Darth Vader sound in her ear, which exacerbates a mild claustrophobia :)
she did go along to Grand Turk, but didn't go down on the 30-foot dive
a blue groper eating a spinky anemony out of your hand might help ;->
she did the instruction part like a trooper though, gotta give her credit for that
I have almost no fear of the water, I don't actually remeber learning to swim and i did squads for years
only bad experience I can rember was getting stuck under a lilo that somebody was laying on at a pool party
that was bad ;->
yeah, there used to be a "beach bus" when I was a kid - they'd basically drive us out to the beach for 4 hours or so per day during the summer
that would have been cool
so learning to swim and getting tan were pretty easy
we used to stay with my grandad in merimbula
(free even - it was a school bus and a volunteer driver)
[13:50:03] <Valen> http://en.wikipedia.org/wiki/Merimbula
you cant actually see the main beach there though
oh, that looks like a good spot :)
massive tides there
if you go in the channel
at peak flow I could just barely make headway
it was great fun
good exercise at least
I used to do a 30 second 50 meter time
went to state for swimming
hmmm. I think I'd be closer to 50 seconds for 30 meters
I think i can do a 35 second now, once lol
south coast is nice in places
I might be able to hook you up with some accommodation down that way if the times work out right
though it would be cool in the (northern hemisphere) summer
(IE you can probably stay at my mums place if I'm there too, she has 3 spare bedrooms)
nah its still pretty hot
oh, good :)
melbourne is cool
your missus would like there probably, aparently lots of shopping
the hard thing is that my wife works in schools, so she's stuck with the school vacation schedule
and it's silly to leave Vermont in the summer, when she has 6 weeks off
yeah your Xmas break is really short isnt it?
we have 6 weeks over xmas
she's got 11 days I think
and if she takes off a couple more, it would be 16 days
(due to the extra weekend)
but she has to make up any time she takes off that way, which is a pain
only real downside it thats peak tourist season, everythings packed
I was thinking it would be cool to go to Singapore / Tokyo / Honk Kong - places that traditionally didn't give a damn about Christmas :)
I think i really want to go to the cayman islands
or after watching burn notice, miami
orly why is that?
again, don't bother, at least not for more than a few days
well, Cayman is supposed to be good for diving, though I didn't do any when we were there
we went to Grand Cayman on a cruise, and had the worst time
we just wanted to bike around a bit, so we found a place that rented out bikes
the people were completely apathetic, and rented us crappy old 1-speed bikes, which I later learned mine had no brakes
oh yeah, my 2nd dream life is to run a fly dive on the barrier reef out of surfers or so, but with the "dive" part being a submarine
MarkusBec_away is now known as MarkusBec
luckily, I was able to avoid getting killed, so we went back to the rental place, and they were completely indifferent to the fact that (a) they had rented out crap and (b) it had almost gotten me klilled
sounds like most tourist places lol not a cayman specific thing
plus, it was a hot, dry, dusty day, and the island is a flat wasteland (at least the part we weere at)
I just like the look of the beaches
Cayman does have interesting submarine dives though
or, take a cruise ship that goes to Half Moon Cay
actual underwater type submarines or the "semi submersables" aka a boat with a glass bottom
that's easily the best beach I've seen
we went on one of those in Hawai'i
nobody runs them in aus
but they have *real* subs at Cayman
unfortunately, it costs about $1/foot of depth, if I remember correctly :)
I was also thinking, underwater hotel, acrylic rooms
thats pretty cheap really
there was an 800 foot dive for $800, and a 3000 foot dive for a few $k
800ft is really quite deep
that second one only has room for one or two people, it's a bubble craft
yeah, that would be pretty cool
they scoot down the continental shelf with spotlights on
I was thinking of running in the 20-30 meter range
that sub was (a) out of order and (b) waaaaay too expensive
oh, that's what we did in Honolulu
so you can still use natural light
saw a shark or two
120 feet I think it was
Would you stay in a "private room" aka acrylic tube 10 meters or so under water with a nice view of the reef
as a hotel?
or for lunch>
depends on the size
wouldn't be large
a big acrylic/polycarbonate dome would be cool
lol so probably standard hotel room size
big meaning ~6m across at least
yeah that might be the way to go
yeah thats the ballpark I had in mind
that would be at least as popular as teh ice hotels I bet
I liked the idea of the tube, floating in the middle of the water column
give the fish something to watch
yeah, but there are privbacy issues :)
thats the best bit, the GBR is stonking huge
the "rooms" would all be hidden from each other by a decent amount of reef
oh - like a houseboat kind of thing?
yeah but mored to the bottom
ie, not connected to other domes/tubes, so you surface to get in/out?
that whole "only 2 people on earth" feeling
that would be cool
thats what I thought
free quasi-futuristic silver jumpsuits for all guests ;->
nah, who needs clothes :)
room service consists of a spear gun and a gril
well you do, at least until the driver leaves ;->
wonder how much you could charge for that
that's the thing though - I'd want to have control over when we come and go
book a taxi
water taxi could come pick you up
come and go from the underwater room
hit the button to surface
ok, that's what I was thinking
just surface to a set of piers, and walk to the main hotel building(s)
nah, you wouldnt get permission to build a hotel there
its a national park
I was thinking these would be more along the line of mountain huts
ok, "sea cabins"
thats the ticket
at the "sea lodge"
so you have a few kayaks or canoes out there, for people to paddle themselves back to shore (or a more central water taxi platform)
(since it's hard to walk)
the reef is generally an hour or more off shore for most of its length
(in a quick boat)
My idea was to run a sea plane service
ok, main water taxi platform for sure
or the water taxi if you want to save some $ at the expense of some time
but yeah thats the idea
call reception, book a trip to shore (or a dive site, whatever)
either make your own way there or somebody will come over to pick you up
this is 5 star service style of thing, not for those trying to save every penny
right - "make your own way" is the part I was thinking of
yeah, I'd imagine $500-1000/night actually
(i mean an acrylic casting that big is probably in the $200k per attempt range)
yeah that sort of ballpark
but you need good stuff for that - restaurants/food service, larger accomodations, nice stuff in the "room", etc
and making it non-distorting is a PITA
though it would be interesting to do things like putting magnifying glasses in some areas
you can make it non distorting from certain positions
well, I was thinking of ripples or other curing problems, not so much having a giant round window that doesn't distort (an impossible proposition, I think)
you need fully enclosed moulding and a special cure cycle

looks like that was done at high tide
all the "light blue bits" of sand are under about a meter of water
probably less actually, its about knee deep
I used to polish scratches out of motorcycle screens, it sucked
I can imagine
its really easy to burn it

ah - here's a relatively good photo of Half Moon Cay: http://z.about.com/d/cruises/1/0/G/X/4/Half_Moon_Cay_14.JPG
the beach anyway
yeah thats why I wanted to go there ;->
not Grand Cayman
is the water that colour?
that's a cruise line owned island

was about where we got the tick infestation I think
pretty close to the middle of nowhere really
well its past eden anyway
place is a hole
looks like a nice hole
eden, yeah kinda I spose
~120 miles south of Sydney?
I mean the tick spot
ahh yeah that was
its about 600km to drive the way we go
or 450 down the coast
both take the same time
upside of the coast road is there is a seafood place about halfway ulladulla i think it is
you order 24 hours in advance and for ~$30 per head you get a hot and cold seafood lunch
they bring out the cold stuff and you go well that was a nice meal
then they bring out the hot stuff and you go "holy crap where am i going to fit that"
my kind of place
you sit on a deck built out over the water
so you can look down and see all the fish swimming under there
if your after the middle of nowhere

I lost a rocket there
I'm more of a forest nowhere guy, not desert nowhere
a line roughly west of the buildings
oh thats not actually the desert
it's desert enough for me :)
desert starts where it changes colour north west a bit
typical though, it pissed down rain for 24 hours before the launch
bogged 2 utes up to the axles looking for the damn thing
one guy bogged a land cruser patroll troop carrier solid when he took it 4 meters off the track to get it closer to the portaloo
he copped it good for that for weeks lol

SWPadnos: >>just import hal in your python program, and make some HAL pins that you'll use to output the positions
Is it feasible to drive Hal motion via Classic ladder directly? That is on my todo list to try, but I thought you might already know. If that was possible could a PyVCP screen be used to tied Hal to a GUI along with classic ladder driving the motion for a cheap and easy motion controller with MMI?
I think the math functions available in classicladder are limited, but conceptually you can run motors from anything that ouputs a floating point number in HAL

SWPadnos: > math functions available ..... Geez, I didn't think of that. I was thinking that I might have a pin availability problem but I didn't think about the math in the ladder as being a limitation. Hmm..
Do you know of any existing Python programs (that I can learn from) that manipulate the Hal pins directly like that? Any help is greatly appreciated!

Thought i'd jump in and look for some general information before jumping off the cliff.
I have (and am buolding a second) 3 Axis CNC router/Mill.
A friend of mine is looking to do for a B and C axis (I have heard axis with all kinda of names, so hopefully those names make sense)
Is there an established process for producing the gCode for to run 5 axis?
meaning, I have a Sphere model and i want to cut it with my 5 axis machine (well, a Sphere on a small trunk/stump"
How would one go about produsing gCode for 5 axis?
I hand write the gcode for mine, but that because its simple gear cutting
I know how to go 3 axis (I use Vectric software (VCarve Pro)
I have seen some videos of a "new feature" for EMC2
and the videos show it cutting a sphere with 5 axis,
I'm guessing EMC2 is control software, not so much the gcode producing part.
its the control
the gcode for the sphere demo was hand edited, not cam generated
gcode generation is separate from emc, but emc can execute multi axis code
some is surprisingly easy to write once you get you head around the moves
is anyone aware of soemthing for producing 5 axis gcodes?
not free and or cheap
what are the optuions that arn't free....or cheap?
OneCNC is one
I got quoted £60000 at a machine tool expo a while ago
I think 5 axis OneCNC is about 4 or 5k dollars

trunnion tables run with emc (5 axis ) in holland http://www.youtube.com/watch?v=DjPCEpZybXs
not sure that was emc, the 'synthetic' z axis feature isnt in emc ( tilting planes )
i thought jan vangilsen was using emc ( for this project )
yes it is - when you write kins for it...
then making gold is there too
tom3p: no, that wasn't emc, it was emc2 ;)
belgium, not holland
alex_joni: it looks like he's translating the z axis, rotation is not about cartesian, it's normal to an arbitrary plane. is that a branch?
yes i mean emc2, emc is pretty dead, paul doesnt even come in anymore
tom3p: no, that's based on kinematics
so if you code it up for your machine, it works like that
ok, did jan post his kins ?
Good evening.Some people have expireance with ethercat on emc2 ?
alex_joni: sorry, did jan post his kins?
no, I don't think so
alex_joni, good evening.Excuse have experience with ethercat ? Have some help?
motioncontrol: no experience, but I know some people used some ethercat hardware with emc2
I do know they wrote some custom code to make it work though
and they only used I/O - not motion commands
alex_joni, please can know this people. i want read in emc2 only I/O with ethercat.thanks
motioncontrol: i dont know the people, but this may help http://wiki.linuxcnc.org/uploads/emc2_ethercat.tar.gz.tar
tom3p, yes thanks i read it.Tommorrow order the master and the slave interface for inizial startup.

ok more thanks for info.a question . i send at souceforge the request for implementation tool lenght compensation along y axis. for read the status have some help?
I don't think anybody is working on that feature. I would be happy to review a patch you submit, if you want to do the work on this feature.
cradek, good evening .yes i thing this improvement is very important for more flexible system.
cradek, i thing a pin or some metode for compensation the lenght tool along y axis.
it would need to be added to the tool table.
cradek, yes i thing is important create a new table for lengh compensation in x,yand z axis
cradek, i want assign at you this feture, i assignment at you in sourceforce or not important?
motioncontrol, assign to yourself
motioncontrol: If you are willing to pay for me to do this work, send me an email.
Yeah, cradek is like the Happy Hooker of EMC.... Easy, just not cheap.
motioncontrol: If there is a feature that you want to see in EMC, you are more than welcome to create it yourself and submit it to the repository.
Jymmm, ok i study , i don't have idea the correct use the sourceforge.But i improvement it.
Gene, from the comfort of his dens heat.
The A axis is not being displayed except in the angular degrees text box. Since I updated to 2.3.4-1
How can I make it display by an apparent rotation of the workpiece about the z axis?
look at the GEOMETRY= line in your ini file
what was your previous version gene_h?
if you have an actual A axis (rotation around a line parallel to the X axis), then I think you need to specify GEOMETRY=XAYZ (but I'm not sure of that)
And I don't have such a line in the ini file at all.
take a look at the sample condigs, and maybe even the manual, and add it to the DISPLAY section :)
I want the whole display to rotate on the z axis, carrying previous work done with it. I just printed the new user pdf too.
any chemists here that know about how thick one can electroplate stuff? :)
rotation about Z would be the C axis
I changed the COORDINATES = X Y Z A to COORDINATES = X Y Z C and it crashes and exits, and I must not have printed it all, what else to do need to get these references?
Mr. Sunshine: Why do you think there would be a limit?
I know that to make very pure electrical copper they plate it out into rods and I think they start with a fine wire... etc... So I am not sure there is a chemical limit, perhaps a physical - what's practical limit.
it depends on what you're plating to what
do you have a c axis?
copper refining plates copper onto copper, so they can go to any thickness they want (more or less)
Found it, in integrators manual, pages 29-30. Now to see if I can make it work... Thanks
7i43: 200k or 400k version?
Also, does anyone in the UK want to combine shipping on a Mesa product?
SWPadnos: I have tried just about all combo's of XYZA, AXYZ etc, but the backtrace is statioinary while the tool rotates about the x axis.
A motion will never be around the Z axis, by definition
motion around the Z axis is called C
Ok, then how do I specify the 3rd axis as the C axis?
Is that in the COORDINATES line?
I believe so. You might need to claim to have 6 axes
I vaguely recall some discussion on the mailing list, let me look.
in the [TRAJ] stanza, set:
AXES = 6
COORDINATES = X Y Z A B C
add empty stanzas for A,B:
create new stanza for C
TYPE = ANGULAR
I think that's not the way to do it, actually
once it's running, you may want to experiment with the GEOMETRY setting in the DISPLAY stanza:
GEOMETRY = CXYZ
you do need COORDINATES=XYZC, but I don't know what happens to the AXES
OOps, just copy-pasting from a rely to the same question.
depending on how old the reply is, it may not be appropriate any more :)
ok, I see the email, but I'm still not sure I agree that it's the correct way to do things
it may work though
Ok, I'll try the blanks, filled in is an exit eventually.
And that is gonna need a lot of editing in the .hal file. :)
To make it work, perhaps, but to see if the visualisation is working you can probably just edit the ini file?
I can't even get it to run now. I fixed the 2 AXIS_3 to AXIS_5 in the hal file but now it just gets stuck in an error loop for about 5 seconds, then quits & cleans up
Ahh, ahem, AXES=4 needed to be AXES=6
And its running, now to see if it runs like I want, BRB
heh - just leave the stepper box off and run the GUI remote from inside the house :)
That's what I have been doing recently
much nicer in the comfy office chair
this chair needs an upgrade
Thats what I am doing, and so does this chair!! BUT, even at feed override=2%, joint 5 following errors. Now what?
did you loop back axis.5.motor-pos-cmd to axis.5.motor-pos-feedback?
Do I need to change that whole .3 stanza to using .5's?
seems like it, escept for the stepgen numbers
and other HAL things - only the axis.3* should change to axis.5*
or, more completely, cat old.hal | sed 's/axis\.3/axis\.5/g' > new.hal (I think)
now you're just showing off! ;)
only if it works :)
hehe, but it doesn't. A short program to drill a hole every 90 degrees as the table turns, only show z going up & down, no display rotation.
Now is when I fool with that order of XYZC in GEOMETRY?
Its running with all that cross coupled stuff in the .hal file, but how do I dis-associate the tool xis from the tool, and connect it to the displayed image?
you replace all the ini value lookups with AXIS_5 instead of AXIS_3
and all the axis.3 connections get replaced with axis.5 (which I gather you've already done)
Yes and yes. Now it shows the table rotation as the bit moving around in a circle. This will do I think, but rotating the display backtrace would be nicer. :)
On the xy plane that is.
I'm not sure I follow
if you do a loop that moves X1 / X0 / G91C15 (repeat), you should see a bunch of thin spokes
(of course switching to G90, or using X1 / X-1 instead)
Next Q, on the backtrace, if I have a tool loaded from the tooltable, should it be showing the whole width of the tool as it moves, its just a line centered on the bit ATM?
I believe the tool image is sized relative to the loaded tool parameters
but I'm not sure it's to scale :)
Neither am I :)
I have to go be social to the missus, might be back after getting us fed. Thanks a bunch everybody.
looks closer to 3 to me
What is the keypad key to move the C axis?
I have about 10 minutes
c, then +/-
I don't think there are direct keys for BCUVW
