hello, i upgraded to emc2.3.1, im having a problem now , using ppmc with axis. debug info is HAL: ERROR:pin 'axis.3.motor-pos-fb' not found ppmc_servo.hal:20 link failed
pid tty stat time command
my email is fx email@example.com, user name is steve10778 on the emc forums.
i put a post up on there also.
i can get emc2 to open up if i use axis sim, so maybe it is a pin that is labeled wrong with the new versions of emc and hardy 8.04? thanks to any who answer
Guest653: is the parallel port connector plugged in?
the transition should be almost seemless... other than machine config
Guest653: how many axes does your machine have?
Guest653: axis.3 is usually "A" and if you don't have one, that is the problem; you would need to comment out or remove those lines from your hal file.
Axis get numbered starting at ZERO, not ONE

i'm new here is there anybody
ok I have a problem
I want to boot emcliveCD from usb, but it doesnt work
the problem is, that i have no cd-rom
someone did something with usb and mentioned the steps he went through
can anybody help me?
the problem is, that I have no CD drive
blinde_l: Do you have a box that DOES have a cdrom?
What kind of computer do you have that doens't have a optical drive?
Jymm: It's an Copact PC
Jymm: available are usb, cf , lan
What is it?
I'd suggest getting an USB optical drive and boot off of it.
jymm: other alternatives?
use a different computer
What size hdd do you have in it?
ok, that's fine.... you should be able to pick a usb hdd for around $35 USD
err USB optical

:[Global Notice] Hi, it seems the EU/US connectivity went for a moment there causing a rather noticable split. It seems stable now but we're investigating the cause. Sorry for the noise and thanks for using freenode! :)
you broke it
no I did not..., I shall tell dad
* archivist blames Valen
it was Valen
they said so in the wallop
* BigJohnT sings "Hi Ho Hi Ho it's off to work I go"
* BigJohnT is getting a wireless connection next week :)
awesome, I have a quote for rails :]
300 eur a pair
well you lot should stop usin my mobile phone interwebs to run irc on
anonimasu there is a guy on ebay who gave us some ballscrews *really* cheap
linearmotionproducts I think?
but ballscrew != ballscrew, I would imagine?
didnt matter too much for us (using linear scales) but they look shiny ;->
comes down to how much you want to spend and how much time you have to fix it in software lol
Valen: this are new rails :)
so are these
brand new stuff he sells
send the dude a message and he makes an auction with your stuff in it or just paypal it direct
got our stuff about a week after ordering
(like, place order to on doorstep)
linear scales wont make your machine perform is everyting else is crap :)
dunno, you get what you pay for.. :)
I need a some and the money to pay for
I think we got a total of about 2 meters of screw, 6 ballnuts and some couplers for about $200Au (~$160-180US)
that's a good price
your rails are bent anyway, its just a question of how much ;->
and the bearings 7200becbp for the ballscrew
got those from a local supplier for ~$60 for 3 sets of 2x axial contact and 1x normal
im buying my stuff off someone we deal with from work
im remote :)
I'm in australia
I know all about remote lol
but rails and stuff are probably cheap when imported from jaapn
I can drive 100km and not actually manage to get to the other side of the city here lol
* anonimasu nods
I think that guy is hongkong
ah, I see
no china sorry
I have his paypal thingo, not his ebay store lol
[13:16:57] <Valen> http://shop.ebay.com.au/merchant/linearmotionbearings2008_W0QQ_dmdZ1QQ_ipgZ50QQ_sopZ1?_rdc=1
thats the dude
yeah check http://cgi.ebay.com.au/3-sets-supported-rail-SBR16-300-750-1000mm-with-blocks_W0QQitemZ250422490511QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3a4e57f58f&_trksid=p3911.c0.m14&_trkparms=65%3A1|66%3A2|39%3A1|293%3A1|294%3A50
for an indication
thoose are ball bushing rails..
thoose are different beasts
he has lots of stuff
(sorry to be anal)
yeah, but no linear rails like the stuff I need
ahh go the balls, you'll get a smoother cut ;->
is the change to TkEMC.tcl that I propose touchy because this is in the Paul C portion of the code? sorry but I had to ask
it was like this self defence class instructor we had a course with once.. "go for the balls and poke them in the eyes"
and run.. :D
once they are down you kick em untill they stop trying to get up
hmm whats c7 tolerance
If the ball rails will take the load though would they not be good?
C7 is about the lowest you would use if your trying to do stuff I think
Its the same as T7 by my recollection
Valen: if you look at a lathe where you have the front rail as a pivot point
and you have ball bushings, you end up with torque around the first one trying to lift the second rail with the carriage as a lever
still not really seeing a problem
sliding rails will do the same
you won't be trying them to counteract torque
they are constrained in more directions
yeah but you dont need that?
want and need are two different things
I was under the impression that a ball based slide is better than a sliding type slide in terms of accuracy?
I guess it's a cash issue..
skf ball slides cost about the same as linear rails
and these guys? ;->
Valen: did you measure how accurate they are?
I'd be tempted to use their stuff, then upgrade the rails later if you need it
I Would be too, but the shipping kills me
also, 300 eur for 2 rails and carriages(that's good)
c7 does not appear to mean preload for a ball screw, ie it can have backlash
archivist: got any idea about linear rails versus linear ball guides?
not at the moment
I see :)

(23:31:41) Valen: all slides are bent anyway, you have to straighten them all anyway ;-> is the last thing i saw
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-07-09.txt
yeah but i don't want to download lots of stuff on this damn mobile phone interwebs
hm, weird you kept talking after it died
well, im gonna go for the rails, beacuse they are easy to get :)
i'm skilled like that
Valen1 is now known as Valen
I love the load rating on theese slides :]
's not bad
the question is wether I should design in space for a linear scale.
this machine will get complex to draw with all stuff
I reckons its worth planning it all out first
nothing worse than having crappy tacked on bits
hey be nice to my milling machine
We should have ours up and running in a month or two, so there might be a bit more knowlage about linear scales + EMC floating about then
hey you havent seen the bastard addition we are doing to ours to get a 0 backlash head movement lol
I jacked up the column last week on a cast iron block
its a normal rotary pully handly type thingie that we are going to just bypass and stick a bolt on Z axis drive that clamps onto the quill onto the side
has like 800 components
week or two before added angles and webs to stiffen
im gonna try to design with cable chains and central lubing
[15:31:50] <anonimasu> http://www.solectro.se/Archive/Images/Products/244/kabelkedja.jpg
adding stiffening made a huge difference
ahh bungie cords off the roof you mean ;->
haha, under the slide
yeah I want to do that
but want to get it working first
but doing like I do things now requires drawing everything
every minute you spend drawing saves you 2 in the shop is my feeling
wouldnt be cutting metal if I had drawn it all :)
and... gained experience in machine building that I can use in a real design
[15:41:30] <anonimasu> http://www.io23.net/ul/files/lathe121.png
bed time for I
rest time for me
thoose damn carraiges was a mess
still at work here
anonimasu, you could place the headstock in the same grooves the rails go in for alignment

i havent seen much activity in SVG recently. today Freshmeat had this http://jsxgraph.uni-bayreuth.de/wp/.
very slick, i've always wanted a browser front end for cnc with scriptable interface.
229 - 1 = ?
what size of 1
Filesystem Size Used Avail Use% Mounted on
/dev/md2 229G 915M 217G 1% /
those maths are near enough for disk calculations
archivist: ah, I've thought about just doweling that in place
only one direction matters, then you only need machine the grooves as the housing is then related to the mounts the rails are on
I am accepted to engineering at the university this fall :]
machine building thesis coming up?
haha, in 4 years
or Ive already made x give me my certificates please
I still need all the math :)
maffs is a pain
cradek: didn't you get a homing thump when you had threads in the wrong order?
on the lathe
skunkworks_: maybe it was following error - not sure
I'm back to playing with this. I can see some #3 signals in halscope, but the signals are fixed, no response from the keypad. Ideas?
I can add the 3rd signals in joypad_v3.hal for everything but the "net vel(axis)" stuff, but that is an error & won't let either halrun do the loadusr or emc start.
Obviously I'm missing a pre-req, but what?
Hummmm, now halrun accepts it, WTF? And the jog axis I want to use for A shows up as "3 float OUT -1 input.0.abs-x-position"
which of course isn't the working x axis. How do I wire that up in joypad.hal so it runs the A axis?
Has anyone ever heard of LANTECH switches? http://www.lantechcom.tw/files/datasheet/SI-Eng/Smart%20Switch/Lantech_GE-24F4GBW_eng.pdf
Got it, for the A axis, the joypad_v3.hal statement is: net velA input.0.abs-x-position => joyhandle.3.in
and the A axis runs as directed.
However, it runs very slowly, how do I scale that, in the "setp joyhandle.3.scale 1.0" statement?
Yup, change 1.0 to 100 gets me higher that th1e motor can run. Kewl!
wth, where's the DL link damnit!
should I chicken out and just go with gang tooling?
good night all
alex_joni: See you in an hour or so =)
[20:37:24] <anonimasu> http://www.io23.net/ul/files/lathe_concept.png
why are both those on the same Z carriage yet on seperate X carriages
because carriages are so damn expensive
oh, you mean no plate on top?
I didnt design that yet
I need to make the bearing mounts and stuff too
though for the X axis, I wont have a rear support for the screw as the other axis
the slab is a bad idea
not stiff enough
I keep saying that too
weld a box up with internal webbing
give me a oven big enough to stick it in after welding
would needling the welds be good enough?
that's about 1 meter square right?
and 30mm thick
ok, get a barbecue...
bricks around it
or i suppose you could do something with epoxy+granite
or I could leave it as is and make provisions for making a webbing later on or casting a base..

so - I found out the 'life time warrantee' on a car axle (axle with joints on each end) is only life time for the first one. The replacement only has a 90 day warrantee
argh. I've forgotten so much math that I can't find the square root of (a^2-b^2)
I know the factors are (a+b) (a-b)
(so don't tell me that :) )
use a calculator ;)
a + b +1
I'm not sure even my HP symbolic caluclator would give me a simplified form of that
SWPLinux: Google bitch... http://forums.wolfram.com/mathgroup/archive/1998/Mar/msg00137.html
I've reduced one example of the polygon turning thing to an equation of this form
SWPLinux: The answer is.... a + b +1
that clearly doesn't work if a=b
sqrt(0) = 0, and sqrt(2a+1) probably doesn't
Ok fine.... the answer is.... 42
sqrt(42) is a constant ;)

wtf... netgear smart switches are web only. argh
I thought mine had a serial port on it
SWPHa! lucky to find that at all
if you're searching on NewEgg or similar, you may have to select managed swtches rather than smart switch
I wasn't, looking at netgear.com
they have a lifetime warranty
I went to see this today... no serial, no telnet, no snmp, no way. http://sfbay.craigslist.org/sby/sys/1256688087.html

I'll have to look at mine when I get home
dude the anser is 0
sqrt(a^2-b^2) is simplified - I don't understand what you're trying to do
well, a and b aren't really that simple, I just thought it might help to get it into that form
I think you get two faces for each multiple of spindle speed the cutting tool spins at
and it may be the case that you need a 3-point tool to get the 6-face stuff in the FC-1540 video
are you hoping to try doing that?
some day, yes
I'm also just trying to figure it out :)
I bet that cluster is about as fast as a single Phenom II 955 (or close enough)
or a core i7 of some sort
I just want the switch out of all that

Cheap 24 port 10/100
that is cheap
If anyone is interested in that, let me know I went down there today,
I can pickup for you
it's just a 10/100 switch though, not managed or with a serial port or anything
exactly, thsu why $20 =)
But a $20 24 switch beats a $30 8 port one
cradek: in case you're interested, I boiled down the effective cut radius to sqrt((D+R)^2-4*D*Rsin^2(theta))
where D is the distance between work and live tool centers of rotation, and R is the radius of the tool
what I haven't figured out yet is the "flatness" of that line
I'm almost pondering picking one up for $20
It comes with rack mount brackets
you probably have enough 10/100 switches ...
if not I can send you one or two :)
I have like 4 port ones, and one 8 port gig, but no rack mount
the gig switch is full =(
do the ears widen it out to full rack width?
they said it's 10" wide
There are rack-mounting plates, which allows user to rack the FE-2400 on a 19’ rack chassis.
auto mux too
built in PS too
no fucking walwart
that in itself is woth the $20 almost! lol
I have a 15 outlet strip full under my desk
ok. battery about to die, so it's time to sign off
see you later
