is that supposed to be some kind of excuse?
Where he lives, it's valid...
where does he live?
who's on dialup, and what s the bitch about?
stay in the game, willya
all I see is archivist whining about someone
archivist: you bitchin about bigjohnt?
he better not be online, it's 4 in the morning there
so we can talk smack about him then?
but then he starts talkin' smack about us in a few hours, and where will we be then?
Jeebus, transcoding an iso with subtitles has taken me days
Linux guru...? Instead of VNC, is there a way to remote desktop to a single machine? where by, it's headless, like microsoft terminal server, but for ubuntu/xorg? And allow multiple users to connect to the same machine?
but you're not restricted to a single machine or a single user
SWPadnos, done it before?
yes, even from a Windows machine (with Cygwin/X)
what's it's name, I just googled ssh -X
no, it's ssh
you pass it the -X option if you want X requests forwarded to your client
you can also use VNC, incidentally
I'd love to have the apps, run on my own desktop, instead of through vnc's viewport/window.
and I haven't set up any machines this way, but you can tell X to accept remote logins, so you can get the full "environment "thing"
I'd love to have the apps, run on my own desktop, instead of through vnc's viewport/window.
windows is screwing up...
there are VNC servers and slients for Linux
it wouldn't scroll down... so I couldn't see if it posted. lol
I think tightVNC is one
i'm using tightVNC right now, as a viewer.
there's another one that I don't recall
oh. then I don't remember the name of the server
ioh, there's tightvncserver
if you run Synaptic on an Ubuntu machine and serach for vnc, you'll find a lot of options
SWPadnos, I'll check that out, after I squash this bug.
SWPadnos: wehn you ssh -X, do yo u have to have X running on the server?
I don't know for sure if it needs to be installed though - apps could require certain libraries on the headless end
has to be installed
I haven't tried removing X
there you go
I used to work with a guy that would remove parts of X on our robots
which was stupid because they all have huge hard drives
I imagine you could get away with only client libs installed, but I bet it's not worth it to find out how to do that :)
SWPadnos: that whole remote X thing just confuses me
I generally don't like finding out that a program will not run because of some missing lib
remote X is even more confusing because the terminal is the server
JymmmEMC, other than the fact that the words "client" and "server" seem to be reversed, what's so confusing?
SWPadnos: gimme an example of something I could test real fast
uh, what do you mean?
SWPadnos: No, that I found out years ago =)
xterm would do it too
SWPadnos: ssh -X hostname gedit?
ssh -X hostanme
ssh -X gives you a terminal
ssh -X username@hostname
then run the graphical apps as though you were in a local graphical terminal
synaptic can get nice and confusing :)
Hey should -X be asking for my fingerprint?
even though I've ssh to the box a zillion times?
tell it to f-off
there may be another layer for the X forwarding
[05:12:59] <SWPadnos> http://en.wikipedia.org/wiki/Image:X11_ssh_tunnelling.png
doh, nm, was ssh to itself *sigh* wrong term window
it didn't know itself?
it will do that
nope, never ssh'ed to itself
ok, I ssh-X, now what?
"if I don't know me by now, I will never ever ever know me" ...
that uses X
X isn't on the box
oh. then you have no X apps there most likely
why did you want to do this then?
if you were logged into that box, and you couldn't run any X apps from the local console (or screen), then you won't be able to remotely either
oh, NOW you tell me. I thought the whole X-Server (client) took care of the GUI stuff even if it wasn't on the remote box
he tolt you that a while back, I seen him do it
and he told you X had to be installed on the remote
so if I didn't have X locally, would it still work?
local to what?
no, you need an x server
you must have the X server on the machine you're sitting at
so you need X on both ends?
otherwise it wouldn't be able to show you anything in X
Well, I'm in gnome atm
it's not the same parts of x
that's what I wasn't sure of when I first answered the question
the desktop manager doesn't matter
I use ssh for X on windows
there are several parts to X, namely the client applications (and the libraries that make them work)
and the server (and drivers and stuff that make the hardware work)
So, why/when would I want to use ssh -X ?
if you have a remote box and you want to run halscope from it, for example
if you wanted to use an X application remotely
like I can run emc on my basement machine from the 2nd story so I don't have to hear the screams
as opposed to VNC and the like?
using vnc is on my todo list
hmmm, ok (I guess)
VNC is more of a remote desktop viewer
ssh gives you a separate login
but you can only run a single app via ssh-X ?
(unless you run screen or something)
start it with and ampersand
so you could have stuff running, head off to the store, remember that you forgot the shopping list in OpenOffice, and log in (via your nebook), and run OOCalc at the store
and you can keep launching apps all day
no, it's a full login session
and if you lose the connection?
then your apps die eventually
and the remote app?
well, that's kinda stupid now (compared to VNC or RDP) aint it
unless you backgrounded it
there used to be a program called XScreen I think, but I haven't been able to find it lately
it may have died due to the various other oprions
well, ssh -X;screen; x-appgoeshere
I don't know if that will work. I suspect not
VNC doesn't lock the machine

what motion hardware works with ethernet that people might want uo use with emc?
I don't think there's anything at the moment
someone on cnczone said there was discussion of adding rt ethernet, so I was wondering
there's lpentyof motion hardware that works over ethernet, but as far as I know, it's only motion controllers at the other end
sure, we've discussed it
there is the Gecko G-Rex, but we'd need to write our own firmware
does anyone use that?
which is a PITA since they use a Rabbit, which only has $300+ Windows development software
no, because it doesn't work with EMC
there is a Mach driver for it
so some people use it, but no EMC user can
charging $300 for that compiler is nearly criminal
I've used it
yeah. I have it too
making the CPU not quite a Z80 is also criminal
that's just funny
since you can't really use gcc to compile for it
surprising they are still around
although for the project I did, it was pretty nice
well, the developers who think $300 and Windows are both evil are a small subset
$300 isn't that much, but the version of the compiler I used stinked
the compiler is more or less free when you buy a dev kit, so it's not really that bad money-wise
that's what I did, bought the kit
I have 9.21
it isn't terrible, but I also haven't done anything with it
well, getting the memory management to work is magic
I actually bought it so I could do development on the G-Rex
but since nobody else in the EMC crowd can at the moment, I kind of dropped the idea
and replaced it with another idea I haven't pursued, which is to make an ARM based rabbit replacement module
I'm just curious if anyone really bought it to use with mach
yes, they've sold at least a few hundred
the rabbit replacement is a good idea
which means there are at least 5 machines running in the world
well, the G-Rex is pretty cool for other reasons - it's more or less a PLC with some good motion hardware built in
I think the main application it's being used for is things like box folding machines
that's an idea
that kind of do something, lather, rinse, repeat application
do those machines use mach?
no, but they can use the G-Rex
it has its own set of ASCII commands
it's not as complete a set as something like a Yaskawa or Galil standalone controller, but it does have synchronized motion on 6 axes, accel and vel limited motion, I/O commands, etc.
and you can write your own Rabbit code also, so it's pretty flexible
that's pretty cool
I guess I should update my firmware one of these days
I believe the GeckoMotion source code is also available
I thought about buying one
me too. then Mariss gave me one :)
(I wrote the serial program he used to develop GeckoMotion)
wow, their customer appreciation sale lasted an entire month
they must be hurting a little
let me put it this way. Mariss sent me a G540 REV4 (the first one off the line) so I could make an EMC2 config for it
then a week later, I mentioned that I had a problem, and we discussed the version I have (he wasn't sure it was a REV4)
it turned out the case was from REV3, so I had no silkscreen telling me about the charge pump disable switch
he mentioned that they had just run out of those rev3 cases, because they had sold out of the first run of 1000 rev4's
that's in one week
when was that?
about a week ago
they sell about 50-75k drives a year
it's hard to remember back before they were an option
it's good they aren't having problems then
strangely, it's only bees since around 2000 or so
usually I can't believe that any hobbyist uses anything else, at least for steppers
yeah. especially with the G250/G251 for the low end now
540 is 4 of those?
4x G250, breakout board, isolated spindle PWM out, isolated I/O for the other lines, and charge pump
in a nice package which is a heatsink
540 looks like the way to go
yeah, it's very nice
it is $300 or so though, so it's a big outlay
finals week! woot!
looks like he made it after fixing up a lot of drives
it has one "problem"
you can't use the pins from unneeded axes for I/O
so if you have a 3-axis machine, too bad - you don't get those two pins for outputs
that's a bummer
yeah, "problem" :)
grex might catch on once bill gates ruins the parallel port
no, I think most Mach users will go to the SmoothStepper
it seems very popular
haven't heard of that
oh. it's another USB-connected FPGA thing
maybe I have heard of it
it has two headers that have the same pinout as motherboard parallel ports
last I knew, he was pretty close to getting threading to work
then again, Steve H said that about the G-Rex for about a year, and then disappeared
" Ask anyone who uses a G100 with mach3 and they'll tell you the difference. The Smoothstepper works!!"
I guess I should email Greg and see how it's coming
how does that work? does it just take parport pulses?
step rate I think
there's some buffering
and I guess there's an encoder or spindle pulse input for threading

can I connect P param from G64 to debug pin to watch it ?
I have strange issues with blending mode
with a recompile, yes. There are several debug parameters exported by motion, and they are intended to be changed to whatever expression you want to view
motion.c: emcmot_hal_data->debug_float_0 = 0.0;
after some errors/warnings from EMC AXIS starts working like G64P1 but gcode initalize it to G64P0.01
er, actually the place you set it is: control.c: emcmot_hal_data->debug_float_0 = emcmotStatus->net_feed_scale;
ok but where to find that P value ?
I dunno; I'd have to look at structure definitions to find it out
[13:52:28] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=50685&page=21
it looks like each element in the trajectory can have a distinct blending value, so it's not quite so simple as I suggested
skunkworks_: did he replace the motors with steppers?
cradek_ is now known as cradek
I think he is using servo drives with step/dir

[13:59:32] <skunkworks_> http://www.cnczone.com/forums/showpost.php?p=532841&postcount=252
ouch, that's only .0001 radius resolution
nice 6-jaw chuck though
he must be using step-servos, then since he refers to "steps per inch"
yeah that would explain all of it - the low resolution and feeds
oops, I tried to read that but all I got was -EPUNCT

[14:02:50] <skunkworks_> http://www.cnczone.com/forums/showpost.php?p=418408&postcount=71
he is using geckos
cradek: what is the supply voltage for the servos?
sounds like initally he could go 100ipm - but maybe slower now because of higher encoder res
jepler: exactly like that
alex_joni: the mesa fpga boards aren't a good match for a project like that, because they don't have any external SRAM and only a small amount of internal block RAMs
what if I would connect some SRAM on one of the ports?
so instead of the 256k samples using the s3board you would get less than 10k samples
then you use up most of your I/Os very quickly.
skunkworks_: I don't remember for sure - I think it's pretty low, like around 80v
jepler: would the flashy with the pluto-p be a way to read a 0-10v signal into EMC?
jepler: surely there must be enough left for the adc link
with only 72 I/O points, you can't control a very wide sram and also have enough left for acquisition
hmm.. bummer :)
the 2 256kx16 srams on the digilentinc board use a total of 56 I/O (18 address, 32 data, 6 control)
er, make that 58
so only 18 left
6 of those could probably be hard-wired to the active state (chip and byte enables)
and fewer than 32 data lines could be used -- probably there's no point to using more data lines than you are acquiring bits
the flashy does 8bit samples
so you could devote one connector to acquisition -- 24 bits, or 23 bits plus one capture clock output for the ADC
and the other 2 connectors for the sram interface
I only see about 11 bits for talking to the flashy
surely you want to capture more than one channel of data though
so 22 for 2 ;)
there are really 8 outputs from each flashy to capture (8 sample bits) and one bit to output (capture clock).
with the sump.org logic analyzer there are 32 capture inputs plus one capture clock output, so you could do 0 to 4 analog channels, and for each one you don't use as analog you could capture 8 digital bits
the java gui already has a provision to treat the blocks of 8 bits as "analog" values
hm I didn't know that the newer flashy boards used DACs to set the gain and offset of the preamp -- my plans didn't account for that
I think they are serial DAC's though
"samco is on a distinguished road"
looks like there's one more output on the s3board connector B1 so it appears you could enhance the logic analyzer to set those dacs
I don't quite get what "period output" is, or how it lets you reconstruct higher-frequency signals..
it says that on your cnczone post
well actually, it says it on everyone's cnczone posts
