Hi Alex. I saw that on Drudge the other day, only the article they linked to had a more impressive title, lol: "Working lightsaber ‘the most dangerous laser ever created’" http://news.nationalpost.com/2010/06/16/working-lightsaber-the-most-dangerous-laser-ever-created
(Complete with Yoda! And I liked their caption on the lightsaber: "Hey, point that thing somewhere else!")

ak. leccy forklift going for 500 squids in 30s
this is going to be the 1980s all over again. loads of stuff going cheap while I've got no cash
1ton tho. I can shift that much with a pump truck
bleh :) silly looking on ebay when I've got no cash
500 squid is not cheap for a fork lift
especially if you dont need a fork lift
and dont have any squid
but its seems a strange token for barter?
was it being sold by a sea food restaurant?
I have just blown up another drive
Hi from germany can i trigger parport STROBE at every Step and Direction change
Eponyme_Le_ is now known as Eponyme_Le
sealive: i think that may be possible by manually ajusting the hal-file
are you wanting to add LED indicators?
but what exactly is a step-change?
cpresser: you got a link where to start this operation
i got a stepper control SMC800
that has 74HCT574 abd Gal16v8 on it tha Handbok says STROME Low activates the Step
It's just a signal. You can change the pinout within EMC
It's DB25 pin 1
Jymmm: i got now my 15th CNC router so im used to emc but not to this control modul
So within emc, map pin1 to your step signal
Jymmm: in the hal
your ini file
i think it has to get a full togel cycle at every step of a axis or direction change
Jymmm: it seems it is not that simple, since you are controlling the steppers sequential, not all in parallel
eg, first send a step to the x-axis, latch the data out; then send a step to the z-axis, latch ist to the controller
Oh gawd, throw it in the trash
The SMC800 is 0.8A / phase and max 28V. Ewwwwwwwwwwwwwwwwwwww
i got to drill 4k 0,5mm holes
use one of your other 15 cnc machines
its not mine
that sounds reasonable
get some cheap china-stepper-controllers :)
or three of those smc800
i will have a look at the C-file that is for Dos-control
If you had to carve a diagonal line, sounds like it would look like this: /\/\/\/\/\/\/\/\/\/\/\/\ (but at a 45deg of course) instead of -------------------
or do it REALLY slow
Eponyme_Le_ is now known as Eponyme_Le
sealive, you may be able to get the strobe you need by using "double-step" on the strobe pin. add parport.0.reset to the base thread (after all the other functions I think), set parport.0.pin-01-out to 1, and set the reset time for some number of microseconds
you might have to invert that pin, depending on which edge the step is latched in
the latch is low
ok, so set parport.0.pin-01-invert
having the pin set to 1 means that a 1 will be output at the same time as all the step/dir lines are changed
and using the reset function (and associated setup) will make the STROBE output go low when the reset function is called
oops, you don't want to invert
i gone do this in 5min back
Thanks so far
remember the man pages :)
* Jymmm hands SWPadnos a cookie
i think best is to take this complede system here to talk its only 5KG
SWPadnos: so i'am ready for input first where do i have to make this change in ini ?
or you can put the commands in the ini file, as HALCMD= lines in the [HAL] section
i use hal file
you'll have to figure out exactly what's necessary, I'm about to head out
the manpage for hal_parport should be helpful
so this igone if i use Stepconf again
Eponyme_Le_ is now known as Eponyme_Le
SWPadnos: when will you be back ?
i'am still online ?
ok close here
SWPadnos: still here ?
someone can help me by doing a hal manipulation
someone can help me by doing a hal manipulation
looks like the SMC800 is pretty weird, you would need to
output channel code and new step phase info for each
channel that needs to step and pulse strobe low each time
( maybe 9 writes for all 3 axis)
if i upload the hal can you dou one axis
Beyond my HAL capabilities...
i tryd the tutorial but my english is not good for this
Odd, I got a pop-up saying I had a message

It was memoserv, but it had nothing to tell me.
anyone know of a good free cam package that works on linux?
Ever start a job knowing it is not going to work out, then find that it goes really easily and well?
Good, Free, Linux. Choose any two.
Have you seen HeeksCAD / HeeksCAM?
yeah I've heard of it
how about good, linux?
I only pay any attention to free stuff
well it'd be nice if cam software wasn't $15,000+
I mean if you're paying that much they should really make it run on linux
danielfalck! Come back!
danielfalck: louipc is looking for linux CAM.
it really works pretty well now

engraving on surfaces is totally doable now
and has been for thousands of years
yeah that's what I was thinking
I wonder who will get all my tools when I die... my son-in-law has three tools and knows how to use 2 of them
JT-Hardinge: SHIP TO: Jymmm
teach him the rest?
I expect to get my dad's tools some time in the next couple of decades. I have no idea what I will do with them.
he lives too far away
hmmm ship them to Jymmm
give em to your neighbour
Sounds like a plan. I doubt I will need any more tools at that stage.
My dad's tools include two lathes, a univesal grinder, two shapers, a horizontal borer and 3 generations' worth of spanners.
We are talking a barn, not a toolbox.
* cpresser wishes for such a barn
I honestly don't know what I'd do if I had a bunch of tools
guess I would do some mechanical parts to improve my mill :)
* JT-Hardinge starts the chipdectomy on the turret encoder
yeah I need someone to give me a job, then I can do it
* JT-Hardinge found out wishing does not work well
but other than that there isn't much I'd make for myself
start beeing a freelancer
amazingly, this did work out for me :)
did you start in your garage?
kind of :P
first I had a room for some electronic equipment... now I got an own workshop
Hi guys, got a "named parameter not terminated" error that doesn't seem to be, what should I look for?
If you were tempering a drawbar collet, what tempering colour would you go for?
2.3.4 I believe
gene_: Have you used "<" instead of "LT"?
its fussssing about line 3, so here is 2 to 4
left_start = -3.100
#x_inc = 0.010
#right_end = 3.100
#x_cur = [#left_start]
it's spelled #<x_inc> etc
parameters are like #123 or #<name>
this is just setting up the vars, no code has beeeeen executed
You need the <> characters. In this case they aren't to aid reading in the docs, G-code needs them.
dummy lessons needed
wrap the names in <> then?
yes like #<thename> = 123
cradek: I spent much of this afternoon making an electric salt-melting pot for heat treating these parts. But the more I read, the less I feel like finishing it. I think I will try using the gas torch.
the torch + magnet + oil system?
I probably won't bother with the magnet
(And, incidentally, the Curie temperature is not directly related to the austenite transformation, as is so often asumed)
heh I think you know a bit more about that kind of thing than most
The only reason I started with the salt bath is that I once spent a week deciding what the absolute optimum quenching medium is for spring steel. It turns out to be Sodium Hydroxide, which the company were already using because it was cheap :-)
curie temperature is when it loses magnetism?
it's like magic
It is. Also, austenite is non-magnetic. But there is a tiny area between the curie temperature and the austenite transformation where what you actually have in non-magnetic ferrite
and I have hit that condition in electrinics service 3 times. Totally wierdsville...
The Weller soldering irons use the effect. The tips have an alloy in the end that becomes non-magnetic at the setpoint temperature, releasing the relay.
Beat me topo it Andy..
Beat me to it Andy..
Anyway, I am making a spare set of collets for a guy on CNCzone. (No, I am not sure why, total stranger just happened to be in the same thread) and I can practice the heat-treatment on his.
Now I think I am doing z wrong, can't get it to run the curve, useing X axis & g18, g3. Do I have to preset z to the center of the radii?
I am thinking I will temper to dark blue, I want toughness and strength more than hardness.
gene_: No, the Z needs to the the start point.
G0/1/2/3 always start from the current positon.
Are you using R or I,K ?
on an ic chip the old one has a u shape cutout on one end and the new one has a round depression on one end... I assume the marked end is the same
on both chips
I have a LM324 chip on the turret encoder and have replaced that chip. The even outputs work fine but the odd ones all report back as 7
More opens or shorts in the PCB? Bad Hall sensor?
schematic? maybe the 7 code can be traced back to the fault
I'm thinking at the moment Peter that the odd ones have a short as 1, 2, and 4 are off during some of the even positions
2, 4, and 8 work fine
[22:17:31] <JT-Hardinge> http://www.google.com/url?sa=t&source=web&cd=9&ved=0CDgQFjAI&url=http%3A%2F%2Fwww.fairchildsemi.com%2Fds%2FLM%252FLM324.pdf&rct=j&q=lm324n%20schematic&ei=Eu84TJfJBoPdnAeituTIBw&usg=AFQjCNEbpFMq2YP7z6MY5FZ2U7iEX_lUsg
damm google www.fairchildsemi.com/ds/LM%2FLM324.pdf
can't find any shorts or opens :?
if a diode is bad could that allow all the odd ones to turn on 1, 2, and 4?
I meant encoder schematic
(a bad diode may do this, should be easily checkable with an ohmmeter)
I'm reading up on checking diodes now :)
I don't have a schematic on the encoder
JT-Hardinge: The Op-amps point in opposite directions on that chip, did they on the original?
andypugh: I'm not sure I know what your asking?
Is the pinout exactly the same?
they are both LM324N chips
I assume they are...
changing the chips did not change my symptoms
Op-amps are just unit-gain buffers in this case?
Ok the right neuron fired:
[22:37:43] <pcw_home> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,30/id,1276/limit,6/limitstart,30/lang,english/#2130
NM thats just a op-amp A-D though sure there was a encoder schematic somewhere...
it looks kinda similar to that but being double sided it is kinda hard to follow on the pcb itself
thats where a beeping continuity tester is useful
so in that circuit the diodes prevent feedback when another part of the circuit is on that line
like a fluke 75?
I kinda thought that speaker looking symbol was next to a diode symbol
I'm still having probs with arcbuddy-1.0. I am giving it x&y data, its drawing the partial circle, but is not outputting any code. Is there a wiki entry for a man page?
gene_: sorry no man page for that
? the exclusive or gate?
(the diodes are used to create OR gates in the A-D schematic)
are you loading it from within Axis
yes, then copy/paste to my code, translating for yz plane.
when loaded in Axis ArcBuddy should paste the code into Axis itself not the copy buffer
It did work once, the segment looked good, but when fged to emc, carves a 360 degree sine wave starting and ending on the degrees input. Odd.
I have 2 diodes that read different than the rest
ArcBuddy is for XY plane ATM only
now to figure out how to tell what to order :/
which is why I was using x & y, but calling it y & z, for a g19, g3 move.
the two diodes are on 1 and 7 so any odd reading will include them I think
Maybe I should explain what I'm doing
I have a long and tall weaver sight base clamped in the vise and leveled, bottom face up.
I need to carve a ditch in the bottom (upper face now) that fits the .5625" diameter of an air rifle barrel
Using a 4 flute ball nosed mill.
.250" diameter mill.
So I would assume to set the 0,0,0 point to cut air at the moment, and cut a circle segment of about 60 degrees as the bottom segment of the circle, at a radii of .565/2, -.125 for the ball nose. Right?
you getting an error or it goes where you don't expect?
arcbuddy has an output window that worked the first time I used it, but has not put anything in the window since.
pcw_home: the diodes have a 48 on them does this help in figuring out what they are?
If I could get arcbuddy to fill its output window again, I could literally play till I got what I wanted.
don't open ArcBuddy in Axis then open it from the terminal
The code itself incrtements the x axis by .010 per pass, traveling a total of 6,2", so the reload time is slow.
as in python arcbuddy.py?
when you run it like that it will put the result into the copy buffer if you press that button
gene_: it should say "Show Me" "To Clipboard" when run from the command line
It doesn't and gives no output, so I presume there is an error in my entry
it doesn't load the program?
x0,y0, diameter .3125, start angle 210, end angle 330, x,y start points 1/2 diameter which is probably the error
gene_: There is an option to make I,J,K absolute rather than relative. As that is the centre of the barrel, I would go that way.
It loads and runs, but doesn't give an answer I can see, or that will load to emc
I just ran that same output from ArcBuddy on Axis sim with no problems
start point X-0.1353 Y-0.0781
G3 X0.1353 Y-0.0781 I0.1353 J0.0781
gene is that the same as you got?
you using vers 1.2?
let me paste that and reload it.
pcw this is a crappy pic of the board http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/id,1276/catid,30/limit,6/limitstart,24/lang,english/
ok, the symbol on the pcb matches a junction diode...
I believe that is going to do the trick Andy, thanks
* JT-Hardinge wonders if this will work http://www.radioshack.com/product/index.jsp?productId=2062587
JT-Hardinge: For the yellow pointy thing?
JT-Hardinge: what are you trying to do?
I have two bad diodes on the pcb
on 1 and 7 so any odd station reports back as station 7
so I need to figure out what kind of diode to order or find
do you have a schematic?
or how did you know you have two bad diodes?
diode checker on my fluke 75
no schematic that I know of
probably 1n4148 diodes
yeah, and anything you have will probably work
almost any silicon diode will work
I have one bad one now for sure... it fell in half when I desoldered it
heh, OMG YOU LET OUT THE MAGIC SMOKE!
do you have any diodes?
no, but radio shack might have them
yeah even they might have something
ratshack 1N914/1N4148-type diodes
(if you're lucky, they keep having less and less every year)
50 for 2.59
yea, my only hope is they have not sold them from the 70's
yeah I bet at least 35 of them will be good
out of the 50?
DO YOU WANT TO BUY A CELL PHONE
then I'll check them before installing them
CAN I HELP YOU FIND ANY CELL PHONE ACCESSORIES SIR
JT-Hardinge: be strong! haha
"Yeah, I need a cellphone with free service"
my only cell phone accessory is a Slim (
"my current plan is $19/month. can you beat that?"
my boss pays for my cell phone
oh crap I'm the boss
tried that but I keep coming back
pcw_home: thanks for the heads up on a part number on the diodes
I wish I took electronics in high school instead of cooking... but cooking was more fun
are diodes rather delicate items?
Normally not, the glass sealed 1n4148s are quite tough
the one I removed fell in two parts as I removed it... just wondering
* JT-Hardinge smells dinner... mmm
Ive heated the glass 1n4148 type diodes red hot and they still worked
