says it goes to (only) 60kHz
60KHz sample rate
more like 10KHz bandwidth
faster than halscope tho ;-)

drouin_: looks good to me, and ready to use with emc2
minimal change of the default config files is still needed (to connect the 4 home switches, if you use them)
thanx alex_joni, I'll go deeper into the doc
my concern was also about the wire temperature control
I've build this machine a couple of years ago
[09:16:48] <drouin_> http://antoine.drouin.free.fr/anton/zaggi_50_60.jpg
drouin_: don't seen that on that page
I've used it a little with a windows program
how do you control the temp?
PWM on one of the parallel port pin
that's easy with HAL
cool - then I'll be reading the doc
HAL is part of emc2, you can read the full doc here: http://www.linuxcnc.org/Hal_Documentation.pdf
I also suggest the User Manual for emc2: http://www.linuxcnc.org/EMC2_User_Manual.pdf
I4m reading that but I must admit that it looks a little bit obscure yet
which one? the HAL?
yes - and the emc doc in general too - I'm just discovering it. so it's alot of volume
I'l read and come back after with questions :)
drouin_: any time
I take it you are from france?
how did you guess ?
from your webpage :)
I have none :)
[09:23:26] <alex_joni> http://antoine.drouin.free.fr/anton/
this is just a junk directory
but it's .fr :)
where are you from ?
not that far
yup, only 2 timezones
is CAM popular in roumanie ?
pretty, but I do it for the fun of developing :)
my "homepage" is more this one : http://www.recherche.enac.fr/paparazzi/doc/
and this one http://www.nongnu.org/paparazzi/
drouin_: great stuff by the first look
drouin_ is now known as poine_
poine_ is now known as poine42
poine42: really great stuff :)
really thanx :)
the savannah page is outdated and the wiki is far from complete yet
poine42: I know how hard it is to write docs
yes - and to keep it up to date
poine42: one question about the board you have
does it take much work?
it says on the page you need to solder some parts
which board ? the CNC board ?
it's not this exact board that I have, it's an older one with ballast resistors - I received it from a friend as a kit
and was easy to assemble - only big parts
alex_joni, one question - what kind of processing power is needed to run EMC - would an old pentium200 fit ?
there is a puppy version out there, but it's a bit outdated, and no real support on it to rebuild emc
that version would run on the P200
ok - I'll find a more decent box then
but currently we advise for Ubuntu (or Xubuntu) with emc2
I think 400+ should be minimum
I'm a hardcore debian fan, so I'll run on debian I guess
poine42: it's not trivial to do the RT kernel
there is a version called BDI (Brain Dead Install) based on sarge though
maybe I'll use that
it features some version of EMC on it, but it's not emc2 (it's a fork of our project)
so you advice to use ubuntu ?
poine42: you could at least use the kernel, then install emc2 (that's what I would advise, because of the PWM control)
I can use that - anyway the box will be used only for the machine
poine42: I'd say.. install sarge, grab the RT kernel, compile emc2.0.3 (last release) on it
ok - will do that
any link for the ace CAM converter cited in the emc2 doc ?
check www.linuxcnc.org -> Links
hmm.. not there
[09:52:09] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
what soft do you use to draw ?
I don't really draw, but usually autocad
does that exists on linux ?
poine42: not that I know :)
but older versions are known to run in wine
there is Synergy CAD/CAM which works in linux
and BRLCad which I heard people use
and so on ;)
I used qcad a little
poine42: alas qcad uses LWPOLYline...
which are 2D entities that don't handle Z depth
yes and it's only 2D
I have a friend who uses solidworks and I'm very jealous of what he does
me too... powerful sw
yet now switching to linux I bought Varicad
I do most of my drawing with perl script - which is bad
wich is not bad at all
but when the only tool you have is a hammer.....
every problem starts to look like a nail
don't tell me
pier_ is now known as pier_gar
lunch time - see you later
alex_joni good afternoon
if someone of you have ever messed with a shift-register such as the 74hc299 please let me know
I have a question about a parameter
I was looking at a page in the wiki and noticed that some parameters listed do not seem to connect to pins ?
danex: what parameter?
[10:14:10] <danex> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?EMCMOT_And_EMCIO_HAL_Interface
usually parameters exist to set some things (using halcmd setp ..) or to check some things, but they cannot get connected to signals
This is what I thought
I have to check some thing, be right back
A parameter can be a bit type, writeable, non writeable floating etc?
danex: we are thinking of dropping parameters from HAL, and replace all with pins
so that one could connect signals to them
That would seem to be a good idea to get more flex
but this might happen who knows when :)
Most pins seem to be created by modules an/or drivers?
and blocks as I have used
alex_joni, thanks for the info
Time for me to go to work
by the way, the photos you took form the antena were a great view.

been a long week
alex_jon1 is now known as alex_joni
so what's happened to alex_joni?
oh, well that's sorted
I was just thinking, there seem to be lots of "I'm completely new to EMC, help with halfile" people, both on the mailing list and here in IRC, is there any good introductory page for them? IMO the wiki isn't particularly optimised for that
there is a chapter in the User Manual
must be a new version
the version I have pretty much only said how to enable e-stop
and how to change pinout I think
hmm, yes that too
but nothing about steptype, switches and so on
Lerneaen_Hydra: I can include it if you write it :)
I'll have to think about that actually
though it won't be for quite some time I'm afraid
lots of introductory stuff at EE now
aaaalleluia! Alleluia!!! It works!!! Emc2 on a Slack 10.2
alex_joni: I am happy!!!
that one was tricky and not over thouh
lerman__ is now known as lerman
it was when damn hotplug was disabled that the machine started to respond to Emc2
* alex_joni wonders what distros emc hasn't been run on yet
alex_joni: I'll try and investigate wath is it that hassle emc
I suspect something about parport & hotplug
emc2 wouldn't start?
steppers were locked
probably soemthing else stilla ccessing parport
probably something else still accessing parport
I'd like to have list of what hotplug started at boot...
isn't it in dmesg ?
don't know how to work out which ir detected by hotplug..
faster rebooting and comparing lsmod list with hotplug on and off
perhaps is not that elegant but I am not an expert
might be a process, not a module though
does /etc/init.d/hotplug stop make it work again?
a process launched by hotplug
* alex_joni goes away for a while
I simpli chmod -x /etc/rcd/rc.hotplug
what to do ... so much to do, so little time
and then there were three
well, 37 actually
if anyone is feeling hungry ... right now I'm enjoying a very pleasant onion bhajee, with a vegetable biryani coming up for main course ...
that sounds quite good
I tried to make a biryani once, it was awful
no idea what the trick is
I can make a lot of passable indian food, but not that
ive never managed to make a decent bhajee
tried many times
can do a very good mushroom and kidney bean balti
but bhajees seem to be a hidden art. a bit liek massalla dosai ... the rice flour pancakes
yeah I tried that once too, heh, yuck
yeah, mine fermented and smelled so bad we had to put the mixture out in the yard
I think lemon is the trick in bhajee
heh you're only supposed to wait one day
this was like 4 hours and the kitchen was under biowarfare attack
ever made sourdough bread? it should have that same smell I think
it's hard to explain, but if you've smelled good sourdough starter you know it
right .. dont think I have
that can go wrong too, I hear it can turn pink or blue!
the dosai turned pink
which is od .. from the smell I expectewd it to turn brown
that's not right at all
ah well, one day.
looking forward to picking up this slide and servo
got a 10-0-10 servo amp for it .. miht have a go at driving it off the G-REX card for a bit of fun
I'd had a go at porting the EMC servo loop to the thing, but I think the other guys had some thoughts about embeddign it in the fpga, but I lost track at that point .. probably better have another look
* danex is back.
Gentlemen, this bhajee sounds good What is the origin country?
Would it be served in an Indian restaurant?
either as onion bhajee
A new Indian restaurant opened here , I think I will try it for lunch
in the UK, about 50% of the restaurants are indian
back to cnc stuff ...
ive head great success with the laser recently, found a few problems and mamanged to et the spot size down a lot, so much better cuts and speed
What type of laser?
infact, had to de-focus it slightly on thicker material, as it was difficult to extract the parts from the sheet
My customer has three LVD brand laser machines
they are OK
mine is Trumpf
they haven made many YAG lasers cutters, most are CO2,
do you cut steel?
about 25 tonnes a month
These give problems with 12mm and thicker material
That is a lot of steel in a month
how many watts are they?
12mm should cut fine with 1800 watts or so
I am not sure, I do not get into that area frequently
1800 can be OK on 15 if set up right
I suspect he doesnt have a lens for 12mm, and is using the same focal length he uses for thin sheet
I know that adjustments to the lense is done on a regular timeing, I do not know if they have different lense sets?
yeah, on CO2 lasers, they have to check the alignemt every sheet or so, make sure it still aims down the centre of the nozzle
they also should use different focal lengths for thin, medium and thick sheet
they should also use very low gas pressures ... like 0.5 bar
I do know that the gas pressure is higher that .5
for 12mm, then that would explain a lot.
you need very low pressures with thick material, high pressures with thin
I cut 10mm all day on 0.5~0.6 bar
I will copy this and give it to the setup person, it may help him with the problems
id suggest a 1.4mm nozzle, a pierce height of 5mm, 1.5 bar on piercing, 0.5 to 0.6 bar cutting ... on 12mm with 1800 watts, a speed of around 0.6m/minute would be a good starting point
cutting height of 0.7mm
if he has a longer focal lenght lens, use that
6 or 7" focal length
and really get the focus point set up real well, either exactly on top, or a mm or so below the surface of the metal
This is the good part of the IRC, GREAT information, a lot of subjects.
Thank You for the Info robin_sz
I have to go now
