Usually people add a lead-in and lead-out, not this guy.
As much chattering as I heard, needs lube too. Lots of unnecessary movements too.
And I thought I heard the fire alarm going off in the background as well.
ok, this is just too cool. Home Built CNC press brake! (caution: mach3 controlled.) http://www.youtube.com/watch?v=38hfwvIbnjo
I wonder how much those 1" plates cost to get cut!
I don't know how to program a cnc press brake. don't know where to begin. Back Gauge, sure, it is only a distance issue. How far to press down for thickness and angle? no clue.

not bad. just add a ball bearing with a spring onto some divots on the wheel to give the 'feel' (I guess it is called detent?)
on EMC2 source, if i only using LPT1 stepper, what files (*.c / *.h) involve?
i need some clue, after that, ill dig it my self
why do you need it for?
im trying to put it on a microcontroller
(i know, it would be hard, since its 32bit stff)
you want send gcodes to microcontroller an d drive steppers ?
1st, G-code calculation?
yes... any help
thats MINUS RT
G-Code to micro =mean- no RealTime needs
prety good idea eih?
(correction, ill place RT Inside micro)
where is "if G02 then" on *.cc
gcode interpreter is in src/emc/rs274ngc
then it goes to src/emc/task
then it goes to src/emc/motion
:) please continue ...
ah, i already on "src/emc/rs274ngc" trying to search G0"
(yeah complicated, but ill start it)
i cant fine 'G'
but, thanks... it reallyhelpfull
alex7: interp_convert -> convert_g's -> etc

sorry i m away 4 awhile back there..
im not on UK, Australia tommorow
1-2 months would be fine
even more time would be ok.
convert_g ....yeah thanks alex_joni
alex7: where in australia?
* Valen is in sydney
might as well be in the uk
lol anyway bed time for I
good day valen

Is it possible to use M66 command in external .ngc file called with O<file> call?
where can i have EMC 2.4.4 ...(i use EMC 2.4.3 from sourceforge)
there is package in repo
you can get the source from the git repository
the tag for 2.4.4 is v2.4.4
how can i access it?

if you don't want to bother with cloning
but better to clone )
its a tar.gz !! ...THANKS
it's pretty hard for git server to roll such files since it's generating them on the fly
so since there is at least someone active... repeating question
Is it possible to use M66 command in external .ngc file called with O<file> call?
(since i cant answer expert question) (i downloading some pdf on linuxcnc.org)
psha: it should be possible
(im reading: EMC2_Integrator_Manual.pdf page20)
I've tried 2.4.4 and head and both fail to execute such file
to be correct they stop after executing M66 line
if line is like M66 E0 L0 G0 Z#5399 then movement is done
and that's all
does it work if it's not in O-call?
if I load this file direct into axis it's running pretty well
but if i call it with O<file> call - no
I'm only about 10% surprised to hear that. Probing is another thing that doesn't work in Ofile-call
It's design descision or bug?
sorry, for emc2-stepper, what is the max step-pulse speed for PC-lpt1 pin to burst out?
25k step/sec? 100k?
that depends on your hardware and the timing requirements of your drives
how about fastest possible today... or 3Ghz PC (cos i already have average 25k pulse/sec)
I don't know the answer to that
how about as you know?
if your setup needs a very high pulse rate for some reason, you should consider an external step generator such as those from mesa or pico systems
those are far superior to software step generation if you need a lot of pulses
what rate does your mill need?
mill G0 will adjust base on that answer...let say if i use gearbox with small stepper
what do you mean gearbox?
4amp is average stepper
I think you might have a lot of misconceptions here
you don't want gears that add backlash
steppers have a low max speed, and their torque goes down as their speed goes up
im afraid...u right
cradek: is it possible to use O-calls inside subroutine?
my understanding is yes, and subroutines can even be recursive
looking into interp_o_word gives me a feeling that it won't work with O<file> calls... but i'm unable to test it...
at least today...
it would be awesome if you wanted to fix up the last problems with O<file> call
I'm not sure what does and doesn't work, but it seems some things don't. I think particularly those that wait for IO.
i'm looking for simple way to do "safe homing" so at last i've hit bug with M66 inside O-call
what is "safe homing"?
so i'll give it a try
G0 Z[safe-height]; G0 X0 Y0
G28 is not working for me (
did u have difficulty on having feedback from switch, to do homing?
(since M66 =Digital and Analog Input Control (I/O))
I'm using it to read safe-Z value from halui pin
not from real hw
other then setting a maximum coordinate?
hm, it's nice solution to use max-Z as safe-Z :)
honestly speaking i have no mill or other hardware except one driver for testing )
M66 is not for hw
M66 is for reading data from pins
as I understand
and what is setup of pin routing it's another question )
so I need (not exactly, what I was asked to implement) is safe homing with adjustable safe-Z value
pins to put wires ...we gave some voltage on them to go logic 1-0 or some analog voltage?
virtual pins connected to halui slider
ok... i gave up on virtual, sorry.
Maybe i'm using incorrect words since I'm not common with cnc
(its to advance on code, for me, im good on electronic&mechanic, i just thoght i can help u)
I'm programmer and was asked to help with emc )
So I see everything from point of code )
pins for me are primary abstract value-holders )
(im new on emc2, hahaha)
and not physical pins
me too )
cradek: it seem that I've digged something
if input-related or probe codes are used then execute_block returns different value
(imho, in case u dont get the answer,maybe it would help a bit(for hardware) http://www.linuxcnc.org/docs/EMC2_Integrator_Manual.pdf
thanks psha,cradek,an all. ill go of offline from now
What's the difference between DXF and DWG formats?
dxf has a published spec and is meant for interchange with other programs, dwg is a private format that autocad uses
Functionality are they the same?
I don't understand how you can follow my explanation with that question - what do you mean?
I've been exporting as DXF for import into some cabinet making software (I dont remember what it is exactly), would it be better to use one or the other instead?
if you're not loading and saving in autocad only, dwg is the wrong format
Well, in this case SW can import/export multiple formats - both DXF and DWG. I just don't know the difference between the two.
Other than DXF is more common place
I think any use of DWG comes from reverse engineering it
DXF is the format to use for interchange between programs
cradek: may you tell me what is 'probing'?
you said that probing commands are not working in O<file> calls
alex_joni you around?

when I start Axis does it lock the file system? When I am done and close Axis I can not turn off my computer with the button in the top right corner. I get a 'can't find' kind of error. I try to open firefox and 'can't find'. Sounds like a locked file system. Any ideas?
any tracks in dmesg?
not sure what you mean by "locked file system". what does the actual error say?
Anyone have a mini black hole I could borrow for like 99 years? I need to cram a bunch of stuff in a really small space!

Heh, I never even heard of the term before.
just pressed a gear through a peice of aluminum. insta-broach.
took about 12ton.
Jymmm, i just tried to goto http://www.nkk.co.jp/
but AB disabled it, i turned off AB (grey), same thing, i removed all entires in AB list same thing... suggestions?
[20:44:30] <skunkworks> http://www.cnczone.com/forums/showthread.php?p=826635#post826635
nm: removing the plugin showed the site just wasnt loading, i guess the message from AB was just poor choice of words, and the result wasnt really due to AB
and you could have jsut turned OFF ABP
it turns GREEN
mine went grey
so now you have to go thru the process of reinstalling it
sahouldn't be so quick to blame. or evne have tried a different browser as a test
it works great, just had a misleading message
It turns green when you have a wesbite that is unfiltered.
like paypal for example or your bank, etc.
places you 100% trust
alex_joni: Wow, it's just quiet today all around, not just in here
is there a possibility to use an usb hid device which has output pins?
All things are possible, when you have the source. But they might not be easy.
acciera: use for what?
you can using hal_input
alex_joni yes, this is what i want
for the inputs i want to use an 28pin joystick
alex_joni you speak german i think?
that might work, but not in realtime
yes, I do
can i ask you a few thinks in a query? cause of german^^
Ah, you want to read from the joystick into HAL?
andypugh not read
i want to write
stuff like status leds
and so on
You want HAL to write to the Joystick?
so i need output
Yes, that is what I first thought.
but what a device has outputs i can use in hal
There is mention of LEDs in http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/hal/user_comps/hal_input.py;h=6515782103cf855ebb3b89ec6b16793f1a9ff390;hb=HEAD
But I don't speak Pythoin
andypugh i mean the physikal interface
what a kind of usb device
hal_input is a generic USB-HID driver for EMC2
the LEDs were from a keyboard
It might just create LED pins, I don't know.
alex_joni or cooling fluid
or stuff like this
i need about 16outputs
I am confused again.
andypugh i want 16 outputs on an usb device
which dont need to be realtime
not the stepper signals
Where does the joystick come in? I have never seen a joystick with more than perhaps a status LED and vibrate motor.
andypugh the joystick device is for the inputs
i use a simulated joystick with en avr microcontroller
which has 28 "switches"
Ah, you might like to look at: http://axis.unpy.net/01198594294
only 6 output pins
could something like this used in emc2? http://sourceforge.net/projects/generichid/
w00t ausie $ is up
time to buy stuff
I have some generic hid chips, but never got anywhere with them.
[22:38:13] <andypugh> http://www.delcomproducts.com/products_USBIO.asp
Anyone know of something that will nest parts on a sheet for optimized cutting?
andypugh but could a custom device such as the one in the url used with emc2? how can i select a pin?
I never worked it out.
But as I said, all things are possible with access to the source code.
the dual-analog pendant must be very similar
andypugh but where do i know what i name has the signal?
i mean with an joystick i know in hal, how the signal is called
or can i check this in halui?
hal gets the signal names from the USB-HID driver.
acciera: Where are you?
(You mentioned you speak german?)
I am in the UK, I could post you one of my spare Delcom chips.
If you fancy experimenting.
what is delcom?
The link I posted?
which one you have?
they look quite interesting
I think mine are 902770
I bought enough of them that I was paying more for the chips than for the postage.
how much you need for one?
How about I just lend you one, for free?
If you get anywhere with it, I might try again myself.
did you allready tried something with it?
I put it on a board and attached a USB cable, and my Mac saw _something_.
I ought to try it with Ubuntu 10.04.
i can try and tell you what happend with it^^
As I recall it didn't instantly work with hal_input and I moved on to other things.
i think, you first have to write a driver for it
that it shows the pins
email me at andy - at - bodgesoc - dot - org and we will sort out the details.
Perhaps. At the time I knew rather less about HAL and nothing about writing HAL drivers. I now know quite a lot about the first, and a fair bit about the second.
i will do tomorrow morning
now i have to go to bed
Crikey! Yes, I had not realised it was so late.
