although at my current rate of sorting steppers doubt i could get them to move it on the axis
did you chat to the Llanelli guy yet?
no not yet
but may need biger ones as yet anyway
I like Sanyo-Denki H series myself
unistrut si avalable from most electrical trade supplyers , its strong and easy to work with , seems like its going to make the machine easyer to build than pratting arround with bits of mdf , and trying to get it as strong as possable
and as i would rather work with aluminium to wood using steel for a frame seems a better option
steel is good and cheap
the alloy systems are quick and simple to use
but low strength and expensive
if you are on a budget
some 80mm Sq 4mm wall box section is a good start
unistrut is good , used the stuff before , its strong , basicaly its like 40mm box section
better still i can get the stuff dilivered :)
but its U section?
its galv coated also
a U is nowhere near as strong as a box
the u is folded back on its self
looks like the sort of stuff they make suspended ceilings from
thay use it for conduit suports , you can walk on the stuff easy
personally I would just order a 7.5 m lentght of 80x80x3mm box
for about 50 quid ..
chop it up in the chop saw
drill it and weld it up
the machines only going to have a 600mm * 500mm cutting aria
60x40 box maybe?
* robin_sz throws AchiestDragon a set of keys
feel free to use the factory
7.5m of 60x40x3mm is 25 quid
the chop saw goes through it like a knife ... 10 seconds to cut it to + - 1mm
making a frame would be very simple
do you have welding equipment
only mig to 500A
and tig to 750A
theres a cnc laser, 50 tonne CNC press and a powder coat plant too
theres a pillar drill and the usual slection of angle grinders and stuff for making the welding look half decent afterwards
and a big skip to put the first two attempts in :)
well, whatever, if you want to use it ... the offers there
well if i dont think this design is going to be any better than the last 3 i will try to come up with one that uses the material sizes you have , and then maybe
use shop4steel.co.uk to discover steel sizes
I dont carry much hollow section .. mainly flat sheet to feed the laser
but i want to try to do it using off the shelf parts , i dont have a mig here , although its on the list of tools neede long term , my old one got taken
* robin_sz recommends Lincoln migs
avoid anything with "clarke" or "turbo" written on it
yes i know
my old one was a snapon
I bought a 500A Murex Transmig for �200 on Ebay
3 pahse though
but a VERY nice unit
the small Lincoln units are wonderful too
i keep looking , but dont have 3 phase though and not easy getting a good one at the right price on ebay for single phase stuff
* robin_sz nods
my little lincoln is single pahse, ebay for �250 ... they are nearly 800 new
could get a single to 3 phase converter , but dont like the idea of pulling 30A from a 13a socket
yeah, no point for mig
single to 3p gainssomething for motors
but mot for welding
or fitting 3 mains plugs to the end , one here , and one to the house on ether side
the 750A tig is single pahse
well, sits across two lives of 415v and pulls 95A
Now that I've disabled X from starting automatically, anyone knwo why I can't run emc from an acnt w/o being root?
lets see ...
is it because you need to load a bunch of modules into the kernel
It worked before when I logged in as a normal acnt when X started automatically.
and logged you in as root?
or single user mode?
nope, just my normal acnt
the script must have been running as root I guess
what script was running at root?
sudo emc.run maybe?
I (personally) never used sudo. Just clicked on the icon on the desktop.
or was the sticky bit set?
The only thing I did was remove KDM from rc.d
ahh, but what did the icon do?
was the icon set to sudo the script?
started emc as far as I know.
yes, but waht command
did you look?
does it do sudo emc.run or just emc.run
even so, why would me logging in as myself in X that starts automatically -vs- starting manually change permissions wise.
as I said ...
if the icon ran sudo emc.run that would work
whereas plain emc.run as Jim would not
Well, I never changed the icon, so it should STILL run sudo emc.run
well click on the icon then!

it doesn't work.
it starts, then quits
if I login as root, startx, then click it works.
So, if I login as myself when X started automatically, whats the difference is what I dont get.
when X was started as root from rc.d
something magic must happen
is the sticky bit set on emc.run?
ls -l emc.run
look for a big S after rw
well, I sus[ect it is to do with X being started as root, which is what happens from rc3.d
so, ANYTHING that starts as init, is always started as root?
hey, you didnt remove the kdm script from rc.d did you
yes, of course the script might change itself to a different uid
how do you LIST your history?
not just up arrow, but actually list it all
cd ; less .bash_history will work too
no, literally 'history'
yeah I know
took a shot in the darl and it worked
history | less
yep, I guess I did..... update-rc.d -f kdm remove
OK, quick rc.d lesson
leave the scripts in rc.d
type runlevel to find out waht runlevel you are in
wtf is 'N' ?
so in rc2.d you will find symlinks ot stuff in rc.d
so if you dont want X to run when you arein runlevel 2, just remove the symlink from rc2.d
S30kdm for eaxample
S are starts .. K are stops
the numbers give the order in which they get run
(so netowrking comes up before apache for example)
ok. So why does NTP start before networking =)
bad sysadmin, no cookie.
alright, so when we are leaving rc2 the K's are executed
so I can have S1blah and K1blah as well
the ACTUAL scripts go in init.d or rc.d on some systems
just symlinks in the rc2.d etc
god knows on BDI .. not played with it in ages
is it debain based now?
well, apt-blah works at least =)
well, I dont have /etc/rc.d/ on my sarge box
all the scripts are in /etc/init.d
right .. beditime
I'll wave at you on Tueday
gonna be in some place called "new york" wherever the hell that is

20mm linear bearing might be less hassle than skate wheels
you see them on eBay from time to time
maybe , but i've already made the bearing holders so not a problem for this one
if it will cut MDF then may use it to make a better machine

they look like .. 4 prescision ball bearings in a slide .. like err, 4 skate weheel
13 for 50 quid ...
looks like theyd need to be mounted in pairs
ahh, might need their special track .. but interesing design
* Jacky^ need to choose slides for my next machine
what you like for woodworking ? KK or KS type ? http://www.hiwin.com/ls/index.html
should KK serier be ok ?
apt-get upgrade konqueror
doh... wrong window
apt-get install mozilla-firefox ;)
well... I was able to upgrade the ram on my laptop from 128 to 256 for $20 =)
old ram mantain high cost ..
Yep... had 2 64MB, and 2 128MB are in the mail. Then I'll just sell the two 64MB's
I MIGHT even be able to sell them for $20, then the upgrade will be for free!
Jymmm: are you ?
you around ?
