today I acquired ... a powder coating oven :)
It is big?
not really ...
but bigenough to batch cure my parts
When you turn it on, do the breakers pop and the xfmr on the pole outside catch fire?
its only 37kw ...small one
Then it's not big enough
its a section from a conveyor oven, im just going ot hang stuff in it and press the 'on' button
if I enjoy the experience, I might get some more sections and a conveyor
I have a friend whose sons' set the power pole on fire...twice
using the 'lots of amps' mehtod?
or just building a fire around it?
Well, the first time my friend (he's 56) got some equipment
He told his boys not to turn it on, he need to add a soft-start to it
uh huh ...
Both his boys are electricians
Well, he went to take a shower
The boys thought they'd be clever, because they really wanted to see if it worked
They bypassed the breakers
uh huh ...
They thought they'd be smart and one would stay by the breakers to pull the plug if things went awry
Obviously, they weren't
My friend didn't even get to finish his shower
They blew the cap off the oilcan on the pole :)
we dont get htose here in the UK, but I can imagine ...
Ah, well...the stepdown looks like a big grey can, hung on a pole
the only time ive seen something like that was when a mate of mine rigged up a generator for when the power failed ...
The top is crimped and sealed
clever people wpould use a c/o switch ...
he just used a big lead and 2 plugs ...
Yes, I read in the channel here about yer mates...
The xeon flash tube
which is fine, so long as you remember to unplug the generator before re-connecting the power to the house ...
I can think of several things that went wrong :)
yeah, the generator survived, the transformer on the pole didnt. it wasnt spectaclulr though, just dead
hes mad by the way
Mad, as in scientist?
Is this the same one who did the xeon tube thing?
Blasted the covering off of a capacitor?
Ah, I just remembered something to ask you.
no .. different mate
I've never had a chance to lay eyes on laser engraver
thay are both mad though
uh huh ...
I was wondering what I should do for a work table
the generator one is the maddest though ... hes the one with an Alvis Stalwart.
work table? Id have thought a piece of MDF would be OK
its not going to get touched by the beam is it?
Well, that's the thing...when I'm cutting wood, it would

# an Alvis Stalwart
how many wats again is your laser?
And I'm currently using shop air for assist
oh, well any bit of metal will do ... 10 watts is well below the damage threshold for metal
My concern was back reflection
at 10 watts? its well below the damage threshold of the les too I expect ...
I'll figure something out
you using a proper ZnSe lens? probably designed for hundreds and undreds of watts no?
Yah, I've got a good lens
10 watts should be just fine with it, refelected and unreflected as you like ... I doubt you can damage it ..
Heck, I was testing the lens out in its new mount with a laser pointer, to make sure I had the thing made right
uh huh ...
Never thought I could feel a warm spot from a laser pointer :)
just a plain ol 5mw one?
I need to plan on making a flying optics arrangement
But that'll have to wait until after the new year
Heh...Alvis Stalwart = recreational vehicle
yeah, need good bearings and stuff, needs to be nice and smooth and straight for flying optics
yeah, he has a few err 'recreational vehicles' ... quite mad
the stalwart is the maddest one though ... the tank recovery truck is amusung as well
That will be difficult, unless I go find a used granite table
If he's that mad, tell him to immigrate to the USA, we need more like him
Actually, the granite slab wouldn't a half-bad idea...just moving the mother is the only problem
You know how to move a 2-ton lathe by hand?
Put a little under where it touches the concrete, and it will roll on it
thats almost handy .. but not quite
I have a lathe to move ..
Crushed walnut shells will work, too
its on a wooden floor
I tried to pry it up to get a roller under it.
Well, then just remember to lift with your knees ;)
that wasnt the proble m .. nice long pry bar ...
and ... now I have a hole in the floor
The floor compressed
Oh, not that thick a floor?
Old tyme shop floors that I've seen were made with solid blocks of wood
Gah...it's getting late
I have to get to the hardware store before they close
Talk to you later, robin
oh, sorry .. youve gone :)
was just having a quick google
it is just my shed floor, 1" floorboard
supermount is not all that bad.
It's quick and easy to set up.
Yes it is.
morning and afternoon
Get all that Cherry turned into chips?
I am really REALLY beggining to wish the inerpreter could handle subroutines and conditional branching
i need to make 50+ parts at a time....
I know the feeling. I wrote a little script that would repeatedly run programs.
so that is 50 repeats of the same code
well I run out of G5X offsets so I have to change variables in the code I guess
How about parametric variables ?
tell me more
Over to Ray...
if that is just assigning vars in the gcode...well I will be doing that
but if I could just do an if() or switch()...
conditional statements would be nice, as would jumps and loops...
or if a script could run programs multiple times but write to generic.var in between
There would be a way to conditionally manipulate variables.
You can write to generic.var between. I did that with a serial numbering router.
Any number smaller than the first of the g92 vars will be written if you put that number into the generic list before startup.
stiil have the script?
Uh. No. It went away when my box crashed a while back.
The multiple run script is still in sf.
I've not tried it in a bit.
oh well...another 10 mb g code file for me
it'll run I guess...just takes eons to load
I will check the script in sf...thanks
paul_c: Don't find kppp or another dialup configuration script in 3.01.
off to the shop...warm up the router and do some sign work...later
maybe not in the one you have - But the package is on the current list
I also don't see any rpm manager. How can I get an rpm into it.
errr... Don't use rpm with Debian
Right but with the earlier live we could at least open packages with kpackage.
And it would try to convert. I think.
This is that softmodem stuff.
I can go back to source and recompile
what you really need is a gcode preprocessor
you could do all the fancy stuff you wanted without complicating emc itself
m4 doesn't have looping does it?
it has recursion
Loops and recursion
There is no direct support for loops in `m4', but macros can be
recursive. There is no limit on the number of recursion levels, other
than those enforced by your hardware and operating system.
they provide a 'forloop' macro as an example
hm, that's not ideal
using their macro to loop from 1 to 999999 takes 20 seconds on this machine, and the process grows to be very large, something like 200 megs. So, yes, less than ideal.
on the other hand, loops to a few hundred are just fine
though, reading more carefully, less objects to how long emc takes to load large files, so a file output by some kind of preprocessor won't avoid that problem.
I was griping a little about that this morning...I am doing parts 50 up...program gets a little long without conditional statements
I have never had problems with program loading taking long, except when I start part way through the file
these files must be bigger than what I consider a large file
I guess you said 10 megabytes
they are often in the megabyte range yes
a big file for me is still under a meg
it's not a major problem...but still an issue
I do need a faster text editor...messing with these files in Word gets slow because of the fancy font stuff
thousands of pages
the one supplied with kde is ok
where would you expect to end up if you wrote g0x0 g92x1 g0x0 g92.1 g92.1 g92x1 g0x0
I use it a good bit
I use vim, and install it on windows machines I'm forced to use
I expect to end up at x-1, but emc goes to x-2
g92.1 followed immediately by another g92 doesn't seem to work
the repeated g92.1 is on a separate line?
all are on their own lines
does it go somewhere else with only one g92.1?
I think I would expect it to go to 2
but the sequence g92.1 (clear offset) g92x1 (set x offset to 1) g0x0 (go to 0 - x offset) should be x-1
I copied it wrong
there aren't repeated g92.1
let me try again
g0x0 g92x1 g0x0 (should be x-1 here) g92.1 g92x1 g0x0 (same, should be x-1 but is actually x-2)
huh, "step" acts weird with that file
brain teaser...let me look at it here..
agree with the intermediate x=-1...
looks like x=-2 is the proper place for it to end up
in absolute coordinates
I have to do some g92 stuff on the machine in a minute
I bring the cutter close to the surface
measure the gap with one of those keychain sprk plug gap guages
the MDI g92zXXX where XXX is the gage reading
am I wrong that g92.1 should clear all offsets?
it does for me
and write to the .var file
g92.2 clears but does not change the file (I think)
I ALWAYS run g92.1 every time I power the machine up
because emc is known to sometimes not display an offset when there is one
and speaking of that...I have to go out to the shop and do that right now
have a quick sign job to work in
10x20 in ellipse....$160
oops, my mistake, it's not a bug

Which kernel are the headers in /usr/include?
the headers libc was compiled against
If you are compiling a kernel module, you need to use the headers in /usr/src/kernel-headers*/include
Don't think I've got anything in /usr/src/kernel*
When I use /src/include I get complaints about 2.6 when I try to make install.
It is quite possible that the kernel-headers package for 2.6.9 isn't on that CD..
didn't realy expect anyone to be compiling stuff against it so soon..
I'm running 2.4.27
and trying to compile a softmodem.\
No luck at all.
I did create a /root/debs and got that going so I can add packages.
Those winmodems are just plain trouble
But there isn't a generally distributed package for the linmodem I need.
Works great on this box wit Knoppix.
I see that kde has switched terminal start in the browser from <control><t> to <F4>
It might have changed since I updated the version I'm running
That sure is a cute tux with the swatter!
When I try to boot 2.6.9 it says kernel panic - not syncing: UFS: Unable to mount root fs on unknown-block(0,0)
Do you have the initrd-2.6.9-adeos in your grub config ?
OK.... Synaptic appears to be broken....
as long as kpackage works, all is not lost..
* paul_c disappears for tea. Back in an hour or so.
has paul hidden yet?
les you around?
guess everyone is off at lunch or tea
just got in yes
was putting finish on a sign I cut this morning
ahhh. I'm still trying to get a good compile for rc46...vitalmod.o
hopr it works out...I want to use the Vital on a bridgeport retro
(still looking for a machine)
actually vitalmod.o is OK but I'm tripping over bridgeportio
Ought to be lots of BP I's and II's
hmmm I wonder if one even needs bridgeportio with all that io on the card
yeah lots of them...but all up north
Yes ... something needs to talk to it.
need to find one within 100 miles
well a BP isn't very big....not too expensive to ship
find yourself a good truck broker.
yes..I have trucked machines myself for the last time
I got the mazak here from NM for $1300
nice. A VMC?
not including loading and unloading which was spendy on 9200 lbs of machine
I really need something about that size
there seems to be a lot of emi in the machine ... vital board goes wild.
I'm now off trying to test in a quieter enviroment....
even after Abdul put in rc filters?
then I can worry about packaging to cut down the emi
well when I finally get it running it will be nice. ... then the next challange is the plc for the tool change
emc/src $ make PLAT=linux_rtai keeps tripping over not finding outb.c in compiling bridgeportio
anyone know a reason?
I need to go back to the compile machine and check if emcio actually has the file.
be back in a bit
maybe paul will be back by then and I can pick on him ;-)
* paul_c goes into hiding
ah! paul is smart and cautious
so the offending line is the same as before...
gcc extbridgeportio.c ............. -loutb.c
tcltkincflags copied over ?
incflags and libflags
in emc/src, do
make clean depend PLAT=linux_rtai
OK I'll be back
Hopefully not with an M16 and grenade launcher...
I corrected grub on hda2 (smithy 2) to point to hda3 (bdi-3.01) and fixed the initrd references.
Also removed the quiet option.
Cannot open root device hda3 or unknown-block (0,0)
Yet hda3 works with 2.4.27
bet it's that flaming udev stuff getting in the way...
and then follow that with the usual make PLAT=linux_rtai ?
well at least it is consistent!
gcc extbridgeportio.c -c -I/usr/include/tcl8.4 -Ioutb.c \
it trips over the -Ioutb.c
go in to emc/src/emcio
and "rm -f .*
NOTE the period !
OK and then make clean, etc
rm -f .depend*
still the same error
OK... quick'n'dirty trick
Delete the entire emc/src tree along with emc/plat
and d a fresh checkout
well not so quick and dirty since I download (fast ) and then burn a cd.
you need a network
Ah... You have the sources on a CD...
I have 12-2 on a cd
delete the emc/ tree and refresh from the CD then - Just as good.
be back later
There is probably some illegitimate depend file lurking somewhere...
paul_c: Hello Paul, are you here ???
I am writing something because of the idea of Alex and me to write a article in that german computer magazine
* paul_c is cursing package dependencies...
I want to know in which year NIST started to devellop EMC or how it was named in that research project
* Imperator_ is searchin the web for information about EMC
the original EMC page of NISTis gone
about dependencies: --force :-)
I have a reference to EMC dated 1993
ok that is good
what kind of reference ?
if i write it starts about 10 years ago i am not so far away from the trues, or ?
[21:08:51] <paul_c> http://www.isd.mel.nist.gov/documents/proctor/sim/sim.html http://www.isd.mel.nist.gov/documents/albus/ifac13.pdf
In the early 1990s, the Manufacturing Engineering Laboratory of the National Institute of Standards and Technology (NIST) began the Enhanced Machine Controller (EMC) program to develop a modular definition of components for machine control
[21:11:03] <paul_c> http://www.control.com/973464084/index_html
EMC is quiet old :-)
Some of it is, yes..
yeh! you should talk to Matt about the early days
now I need to go off and test
dave-e: There was probably some illegitimate depend file lurking somewhere...
It is good to be past that...of course this still depends on testing.
and the elimination of emi
Hm, on the Linuxcnc Homepage at EMC in action the link describes the Triton Shaper machine as a gantry machine, but it s a portal machine
or how that type of machine is called in english, but it is no gantry
in my thinking
Arrrg I hate MS Word
Got a suggestion re the linmodem stuff. I can not boot the 2.6 kernel, can't compile 2.4, and can't run a precompiled
which linmodem is it ?
[21:50:30] <rayh> http://www.smlink.com/main/index1.php?ln=en&main_id=40
look under linux after you agree for me to the terms.
Or I could send you the file I downloaded.
* paul_c reads the EULA....
There is no way I can agree to those terms...
Well I can't win them all.
If you send me the tarball, I'll have a go at compiling it
On the way.
Any further hints on 2.6 not finding a good root directory?
What is the file size of the 2.6.9 initrd ?
that looks about the right size.
I copied it and mounted but had no idea what I might be looking for.
There was one small file that said something about hda3 but...
mounted it ???
mount -o loop
with initrd image ?
Yep. Found that command left over from the knoppix days.
Nooo... there is nothing to see in an initrd image
There is a whole set of files in there.
should be a collection of kernel modules...
I did that with boot.img to change stuff.
boot.img is a floppy image
There are a few of those along with several executable like mount and umount.
Yea and for it you have to use -t msdos
I take it there is nothing to be done from here on the initrd file.
Well.. I never... So that's what an initrd looks like from the inside...
A-l-p-h-a|Nap is now known as A-L-P-H-A
rayh: 2Meg tarball on it's way back
The EULA prevents me from distributing a module on the CD
Right I see that. We'll just have to let the consumer cross that bridge if they need to.
Is this standard fitting on the Sherline boxes ?
There are a couple of .deb packages on www but...
I don't really know what they are doing now for the modem. Nothing, I'd bet.
If they are, I'd be willing to ask if we can install it on each device.
They could make it a separate thing in the install process.
or persuade someone that it might not be such a good idea...
Yes. That is an alternative.
The kernel module would have to be recompiled on eacj kernel upgrade..
It would quickly make a mess of things.
for $2500 surely they can afford a real modem
This is one of those all in one motherboard specials.
Yep. It does slow down processes quite a bit when it is passing data.
File is arriving.
10 bits... 12 bits... 16 bits...
That's it. They kinda dribble down the basement wall.
