03petev 07TRUNK * 10emc2/src/hal/components/boss_plc.c:
-Cleaned up init code.
-Made spindle control into state machine.
-Added tool change handshake so brake would remain on during tool change.
-Added amp fault generation from amp enable and amp ready. Need to wait a
bit for amp to become ready after enable. If it does not become ready,
indicate a fault.

Looks like that big is a memory leak
wow, I had heard about the (plainclothes) cops who did the drug raid (no-knock) at the wrong house and shot the 92 year old, but I hadn't heard that they planted drugs there to try to cover it up
I mean holy crap
also they shot 39 times, hitting her 6 times, and themselves several times
got a rt problem --1848: error: unexpected realtime delay
on board video? usb devices?
usb plugged in.
memoty stick----ejected it.
yeah, I saw that once too on my machine
see if you get the realtime delay now. I have had a few motherboards that have issues with usb devices plugged in.
well I always have at least one usb device plugged in, and have never seen a problem
only seems to happen when a USB stick is plugged in
what is your hardware?
usb memory sticks here also. (only thing i have had issues with)
virge s3 video
shared memory? or pci/agp card?
do you know what kind of motherboard you have?
would it happen to be an intel chipset http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingDapperSMIIssues
compac running amd 800mhz processor
cradek: who got shot?
[02:26:16] <cradek> http://news.yahoo.com/s/ap/20070426/ap_on_re_us/elderly_shooting;_ylt=AgSYVupNSp.yr7kBlq.Jk_5H2ocA
lots of folks, but the innocent 92 yr old lady was the only one who ended up dead
wow. unfortunately this kind of thing is not too uncommon though.
why would they no-knock in plain clothes? that's just asking for trouble
with guns drawn too, I suppose
no-knock should still be illegal anyhow. some way to serve a warrant...
it's clearly a great way to get shot at
and this case was a 'war on some drugs' thing too - particularly insane
yeah. I don't have any use for drugs, but I have even less use for the 'war on drugs'.
'war on some drugs not profitable to big business'
the woman fired _once_
cops fired 39 times, probably in a complete and total panic
jmk-core2: she missed them all. they shot one another and killed her.
I imagine the cops get scared and adrenaline takes over their brain...
yep, what a fsck up
the article says she fired thru the door, which wasn't exactly smart of her either
mozmck: then they're a little short on training or smarts or self control or all of the above
we recently had a case where cops went to serve a warrant, knocked, and the guy shot thru the door - the bullet went in the armhole on the vest of one of the cops and killed him
jmk-core2: true, we should expect more from our 92 yr olds
yeah, too many young guys go in for the power they feel. Had a couple of friends became cops because it made them feel big.
lewin1 is now known as lewing
mozmck: that's gotta be the wrong reason to become a cop but I don't know how you'd go about getting just the good guys who do it for the right reasons
jmk-core2: yeah, but if someone was kicking your door in no telling what you might do! Would scare me some I reckon...
cradek: I'd say there should be a higher minimum age requirement - 21 ain't old enough; maybe 35 (I'm not there yet)
Age wouldn't fix everything but would be a start...
plainclothes no-knock is just plain stupid
mozmck: true, it might help if it was nobody's first career
mozmck: many people aren't at all grown up at 21
those guys probably had themselves all pumped up, and were sure a dangerous and armed person was on the other side of that door - that kind of tension is a disaster waiting to happen
mozmck: I bet some 'seeing the world' between high school and 'the force' would help
cradek: I believe so. Wisdom comes generally with age and experience, not just education.
but some people never wise up
one of the cops planted dope in the house after the incident
[02:58:22] <cradek> http://policechiefmagazine.org/magazine/index.cfm?fuseaction=display_arch&article_id=971&issue_id=82006
that means he had it with him... I wonder why.....
jmk-core2: just in case of "emergency" I'm sure
that kind of mentality is a problem, and I doubt age (or education) would fix it
it becomes us against them, and they don't care about right and wrong anymore
jmk-core2: more dope can't hurt when you just want to "get" the "bad guys"
yeah, age doesn't cure everything.
sorry I work with an ex-cop and I see this in him big-time
"Requirement #1: You must live in 'Da hood' and/or 'projects' for a minimum of one year. If you are not a junkie/thug/rapper at the end of one year, you have passed step 1"
planting dope seems common, I hear of it all the time.
looks like some people are pushing for required college education
in the incident that happened here, even though the bad guy shot (and killed) one cop, and they did return fire, he was not shot, and was taken into custody unharmed....
thats a different class of cops there...
no, they missed
but thats normal for cops, and most anyone else under that kind of stress
Ok I got about a 12" spread \, but that's bad...
but the key is - they stopped shooting, and arrested the guy, they didn't perforate him
Subject: ***** is coming back tomorrow !!!!!!
oh hell, they have so many non-letahl weapons these days...
***** has completed her jury duty assignment and did the right thing by
finding the defendant guilty. She will be here at 7:30AM
^^ email to whole company from my HR director (ex-cop)
cradek: that's "some company"you work for
if he wasn't guilty, he wouldn't be in court, right?
he'll never make it onto a jury
Jymmmmmmm: it's ok, but has a few black eyes
I MUST be guilty if I say I dont want my car searched
jmk-core2: I hope to hell not
cradek: yuck. assumes he was guilty because he was charged! and don't get me onto (rigged) juries!
cradek: save the email, and if he ever gets called for jury duty, send it to the courthouse ;-)
I've juried twice and found most people there smart both times
Note: If you EVER get pulled over and are asked if they can search your car, ALWASY ask "what for" befor econsenting.
I've never even been called, I have no idea why
my wife has served 3? times
I've been in three times, served twice
the juries aren't the problem, it's the rigging process (voire doir sp?) and the withholding of information that I have a problem with.
Jymmmmmmm: my alternate strategy is to say no
cradek: But always ask why, if if you plan to say no either way.
s/if if/even if/
Jymmmmmmm: that's an interesting idea, I'll try to remember
Jymmmmmmm: I've never been asked (white male, nice car)
cradek: If they say "for weapons bombs" and they find dope, your free.
Jymmmmmmm: I doubt that's true
I suspect that they will have to try very hard to use the dope as evidence
Jymmmmmmm: a warrant has to specify the things to be searched for - a warrantless search by consent, nope
that's one reason why you say NO
you consented to weapons search, not anything else.
even if it's inconvenient and you have to wait for them to do paperwork, make them do it
sure, they'll take your dope, but you'll be in the clear about it
Jymmmmmmm: "because I'm conducting an investigation"
maybe different outside of Calif,
Jymmmmmm: I'll never be worried about them taking my dope, since I'll never have any
doesn't really matter
jmk-core2: haha, unless the cop has some "just in case"...
they shouldn't be asking to search your car anyway, but if you piss them off, there's nothing that says they couldn't plant some.
I doubt I'll ever find them asking to search, but I'd play it by ear
if I let them search, I would insist on watching the search
I've unknowingly had open containers of alcohol in my car
(an "acquaintance" hid them there)
... when I was underage
jmk-core2: it really wouldn't matter at that point.
there's no reason not to say NO
once you say yes, you relinquish all control and protection of the law
I think they can still search even if you say no.
There no reason for them to be asking either, biut they do
mozmck: surely saying no is a good idea then, if you want to challenge an illegal search later.
I want to laminate lil cards and when they ask, hand em the card.
in fact I know they can because when I was called for jury duty one time the lawyer told us so
said they've made laws that allow it.
mozmck: only if they can show cause, and they won't ask if they could.
I started to say something about the 5th amendment (is that the right one?) about warrantless search and seizure and they shut me up quick and booted me :-)
Justice is blind alright
booted? as in let you go?
or as in stuck you in the back of the cop car and searched anyway?
yeah, it was during the selection process.
jmk-core2: they threw away the key
this was in jury selection
I thought you were talking about the car search thing
jmk-core2: he was, just wasn't HIS car =)
the court case had to do with a car search apparently without consent
[03:18:18] <jmk-core2> http://en.wikipedia.org/wiki/United_States_v._Ross
I coulda sworn I changed the CMOS battery on this system
This is sad.... this mobo has builtin ati video with 4mb video ram, but draws better than the ati card I have with 8mb vram
thought, not at the same resolution
jepler: cradek Within axis, are there any keybindings for SHIFT + (direction keys)?
SHIFT or CTRL or ALT, doesn't matter
I don't think so
In TurboCNC, I get really spoiled by having regauler jog by hitting direction keys, or FAST jog by ALT+(direction keys), is it possible you guys could add that to your feature request list?
I agree something like that would be nice
I'd still like to use my external numpad, to jog around next to the machine.
always games with xmodmap ;)
so I could remap a key on the numpad as a ALT,CTRL, or SHIFT key if I needed to
ds3: the key remapping can be done within emc
dumb question, but what is CDS.NGC, I can't tell from the screen what it is =)
circle diamond square
just engraved my first convex engraving, around a 1.5 inch pc of clear acrylic. only with xyz
it came out nice except my stock was off center like .020cuz i didn't indicate it in
chr0n1c: now try it with only XY =)
i'm building a rotary axis :D
but.. it's not done yet
after that, try it with inly X
it would just be a line
if it was only x
maybe not even that if moving the z down to the stock counts
you are just not trying hard enough =)
then it would be nothing :(
you are just not trying hard enough =)
if you apply yourself YOU CAN DO IT!
* chr0n1c uses the force
there ya go
fuck it.. why don't i set the machine on fire and go back to doing it all by hand with a rock
chr0n1c: do you have a rock already?
well... i live on one
close enough, heres a book of matches
uh got lighter fluid?
or.. i'll just run the slides at rapid with no grease till they melt
go x0 y0
g0 x1 y1
you have the ulitimate rubbing of two sticks already
but i love the machine too much to hurt it
you already hurt its feelings by saying you were going to set it on fire
it enjoys a lil teasing now and then
it's a tough lil bitch
a buddy is comin over tomorrow to start working ona 24" x 48" machine frame
i can't take this little mini mill stuff
it's gonna be a gantry machine...
prototype out of wood then a steel frame after it works
OMG who wrote tort.ngc!!!
what does it do i never ran it lol
and share damnit I want the same drugs they were on!!!
just look at it
Jymmmmmmm: it was generated with a program
cradek: ah, has anyone ever ran it before?
I mean milled it
run it, sure, it was a nice test for the planner
it surely can't be milled
holy holy holy... crap batman
was that jsut math chris?
that is 3" x 3" x 1.6" correct?
or did you do it in cad?
jepler wrote a program to generate the gcode directly
i could draw that.. but it would take hours
of typing in points...
each thing is a different feed, and there are nasty helixes and stuff
it was a good test - found some bugs that would have been around forever otherwise
if it's only 3x3x6 i can run it
If I slow it down enough to not break a tool, it might be interesting
it would just be chips left i think
we had one that turned the rotary axes too, it's been lost I think
only one way to find out,
i'm running it now
it would be good to tram a dowl.. then run that .. and re-tram the dowel to see if your maching repeats
uswing what tool?
it's cutting air
and it's in MM
not inches i believe
it has a g21.. thats mm right?
so if I make it g20 instead, it'll be inches?
yes, but it'll be 25x as large
so the 3.23 callout I see on the screen won't become 3.13 inches?
it's 3.3 mm
uhh or i dunno i don't do metric
the program is probably 3" across
if you have your gui showing inches, it'll show 3 in the preview
if you change the g21 to g20, it'll be about 80 inches instead of about 80mm
how do oyu know what the setting is in the GUI ?
it's on the menu
you can change it any time
you can work in either system
i wasn't thinking.. the display is in inches
the gui can present either system to you
the gcode can be in either system
the machine (ini file, leadscrews) can be in either system
these are all separate things you can control
long live us measurements!
ok, got it... still trying to learn your baby here cradek =)
is your machine running ok jymm?
Can I edit the gcode within axis?
chr0n1c: No, I still have to connect the db25 to the motherboard header and bring it out the back of the box
if you are running cvs trunk and have EDITOR= defined in your ini, AXIS will start an editor on the file for you
but within, no
ok, good to know
I doubt that will make it into emc2.1, but will be in 2.2
it's all good, was just asking
have you seen "codeshark" for windows chris?
it does highlighting.. automatic renumbering...
nope I don't use windows
not even wine?
nope, I really have no windows apps
i guess that's one way to learnlinux quick
i grew up on windows... i don't mind it's quirks, i learned to work around them over the years
and now i'm used to all the quirks
so linux is taking some time to get used to...
the last windows I used full-time was WFW 3.11
after that I used OS/2 for a while, then linux and freebsd since
i installed that on the second computer i ever owned.. on like 15 floppies
[04:15:03] <cradek> http://timeguy.com/cradek/01161921561
ya know, this whole getting shocked every time I touch the PC case is getting old.... I REALLY need to run a ground wire
with some old speaker wire lol
shocks can keep you awake though
if you ever doze off while running a long program... jsut touch the case
ha tort is still running
it hasn't choked yet...
at like 3 ipm
is it short for tourture?
keep spraying a mister, if everythings soggy, theres not much static ( just soggy :)
I wonder if I can install the PCI nvidia card I bought with 128MB vram on it
has anyone ever tried "upgrading" a video on an existing system?
just change the driver in xorg.conf
is nvidia nv ?
that sounds about right
ok lspic -X sees the new video card on PCI:1:3:0 but X chokes on that
any comments in /var/log/Xorg.0.log?
no matching device for instance
is nvidia NV ?
you can try forcing it
do a "man xorg.conf"
look at the section on "BusID"
this assumes the chip will behave reasonably if driven by older drivers
nvidia is nv
yeah nvidia binary + emc is supposed to be badness
hehe, ubuntu people are silly
Jymmmmmmm: psu chassis should be gnded, use crush washers or something similar to make sure the pc case and psu are making electrical contact
cases have that paint layer alot
for BusID I have a line right under the Driver line that says: BusID "PCI:1:0:0"
same with screws on the back for holding side panels on
should use lspci or cat /proc/pci (?) or to see what your card is
or cards are
renesis: so should the power outlet =) that's what I need to run a ground to
ughhh.. my boss jsut called to wake me up.. how rude.. i'm only an hour late so far
i guess i need to take a shower and go cut steel or some shit
ah - yah... I would fire your ass
well, i'm the smartest person there
they would be stuck with nobody to run the puter :D
lol.. i don't mean to toot my own horn but ya know
get to work
i get to go see stephanie at the silkscreener's shop :D
she is tuff!
and she says i'm her fav ')
I work for a 'silkscreener'
we call it screen printing now - the screens are not silk anymore
bahhh ... gotta take a shower so i look sexy for stephanie... :D
that definately was tmi
I dunno, tmi would be "I haven't taken a shower in two months"
he already talked about smoking dope - so I think anything goes ;)
* crepicdotcom took a shower last night
crepicdotcom: your going to school - your not expected to shower.
yeah but i live with my girlfriend. shes expects me to shower
if you don't like to shower just buy a sailboat, nobody expects you to shower months on end
Dallur: so you're building the boat to cut expenses on water?
now I understand what you need emc for :D
alex_jon1: yup, moving off land and roaming the seas for a bit, kinda like a glorified mobile home
you can allways tie a rope on a body appendage and throw yourself overboard in leu of shower
alex_jon1: although it's a bit ironic since we have the lowest water/hot water cost int he world due to geothermal energy, I think I pay 10 cents per cubic meter of 80° water and cold is free
Dallur: will you pay me a visit if you start sailing?
it's possible to sail up to where I am :P (at least it should be..)
alex_jon1: of course, There is great sailing in the Adriatic and I plan to cruise the Slovenian/Croatian waters for a bit, then move south and eventually cross the Suez
Dallur: mediteranean sea, black sea, danube, dtd canal
and from there on the bega canal..
it runs right through our city :D

oh, I think it is
alex_jon1: hmm that is quite far inland :)
[14:08:08] <alex_jon1> http://en.wikipedia.org/wiki/Image:Bega_Canal.jpg
alex_jon1: I might have to drop my mast though, those bridges don't look that high ;)
and you probably need a motor to go upstream
alex_jon1: I have a motor, aux motor that is
I see a mention of one of the local registered boats, that has 160cm immersion
(if that's the proper term)
alex_jon1: they call it draft for boats ;)
ok... then draft it is :D
I guess you don't have more than that?
alex_jon1: nope, mine is 1.5m
this was 50 years ago though :D
alex_jon1: river boating seems to be making a comeback though, now there is a bunch of people that travel through Europe on river boats, the UK has just finished several large projects to re-open the canals and it seems it might become quite popular over the next couple of years
the channel was started in 1726 :) so it's not quite new :P
what irc network?
so I installed the latest sun java on here and now the tab completion dosn't work anymore on this java applet
skunkworks: yay java

Annybody knows how to connect a Phase-drive on EMC2 ?
ito iam is hear
we need conect Phase-drive in EMC
Yeah, There is some sites that guys got it, like A sketch machine
A guy put steppers on a drawing toy using only ULN2003
my phase is a little more complex, but it seems koooool to me
i am using TurboCNC, but it sucks a lot
I insttalled the CoolCNC on a machine to test it, but i have no Dir-Step drivers
PLZ PLZ PLZ Help
Ito-Brazin: you need to look at the stepgen hal componant.
Oke, thanks! Have ya more cheats ?
[15:03:58] <alex_jon1> http://www.linuxcnc.org/docs/2.1/html/hal/rtcomps/index.html
Ito-Brazil: how many phases?
I have a phase-drive that uses 4x TIP122 to drive a stepper
using all 12 pins i drive 3 steppers
and using annother board, to linear regulating the current, i can drive upto 45V onto my 6V/1,2A steppers
getting same or more performance than a chopper drive
and spending 1/10 of $$$$
some.. Not more ;)
theese boards are opensource already
yeah, more performance i gess
have ya seen a CNC going on 20 000 mm/ min ?
i have a video, but dunno how to put on web
I got 9 kHz on steppers using full step on it ( 200 steps/ revolution )
I gess it´s a cool stuff to put on EMC, cos its very cheap, it´s opensourse too and gets good performance
but i can´t realize how to use a phase-drive on EMC, for me the best CNC controller
i will try to put it on googlevideo now
so you basicly have 4 phases..
I suggest you get the latest emc2 (2.1.4)
the best would be to do that by using the LiveCD from linuxcnc.org
then you modify one of the included configs (probably stepper or stepper-XYZA)
I downloaded from there, but the CoolCNC ISO. Isn´t good ?
coolcnc iso is older
and not updated
can you tell me where you found the link>
Ito-Brazil: how do you want to drive the motors?
one phase active at a time?
two phases active?
full step plz
[15:14:57] <alex_jon1> http://cvs.linuxcnc.org/cvs/emc2/src/hal/components/stepgen.c?rev=1.56
2 phases at time
It improoves the torque
[15:15:11] <Ito-Brazil> http://video.google.com/videoplay?docid=3750178924754241914
look at types 6
Sorry low res and darkness, i was very exited :´]
State Phase A Phase B Phase C Phase D
0 1 1 0 0
1 0 1 1 0
2 0 0 1 1
3 1 0 0 1
0 1 1 0 0
is this what you want?
I founded the link on ITALIAN DOWNLOAD
Have ya seen the video?
is that good enough to a Phase-drive?
I gess i need not change to a chopper, huh ?
i have annother video, with a 5 kg bag on top, better resolution
The coolcnc link is on this page:
[15:20:20] <Ito-Brazil> http://www.linuxcnc.org/content/view/2/4/lang,it/
sorry much typing, and my english!
So you say thet i must use UBUNTU with EMC2 to work better? CoolCNC works great on anny computer heare. You know, 3rd world, there is only slower PCs available to work on machine
PCs are very expensive heare
Ito-Brazil: you don't have to use ubuntu
_but_ the coolcnc is a random version from quite some time ago
a year or so..
so if you want to use updates from emc2, you'll be stranded..
Will the modificantions on phase control works on coolcnc ?
thanks for your time!
ito tou hear?
please somebody to know to conecty phase-driver in EMC
[15:37:32] <Ito-Brazil> http://www.linuxcnc.org/docs/2.1/html/hal/rtcomps/index.html

I need to configure the TYPE6 phase steps but there is no picture to see it
anny help is welcome, thanks!
boy - it is a beautiful day here.
cool - going to the pjirc site finds the same problem as far as tab compleation. No fix but page down does the same thing :)
guy just installed fiesty on his laptop dual boot. worked great.
(he is not a cnc'er) ;)
Hey, do you guys know of anything in linux that will let you save/restore CMOS settings by chance?
wouldn't that be bios-level? can you from a running OS change cmos values?
Yeah, I can... from DOS I know
just like you can update the BIOS from dos
Jymmmmmmm: how is the machine running with emc2?
skunkworks: I can't get anything higher than 1024x768 due to the onboard video card only having 4MB, but is running a LOT smoother when I have axis run a file
And there's a HUGE difference between the P3 600 768MB and the Dual P3 1Ghz with 2GB ram
even though the RT kernel only sees 1cpu and 1GB
I have ran my router yet though.
Though, I was actually thinking of putting the xylotex card inside the PC case as this mobo has a header for paraport as does the xylotex
did you say on-board video - as in shared memory?
No, not shared memory, dedicated 4MB
ah - good
But, I think I know why this was in the trash.... the CMOS battery is low, even though I replaced it =)
Great if you leave it plugged in though =)
though it only does 114 bytes
I have a ati rage 128 in the dual proccessor one - and glxgears actually spin smooth
no clue. something I scavenged from work.
only 2 pci slots on this server mobo
it was going the screen saver at 30fps full screen and 60 in the default window.
for a dual proccessor?
its a server mobo, as in 1U
made to rackmount
dual nics, serial console
I tried a PCI nvidia card with 128mb vram last night, ubuntu livecd won't have anything todo with it
so, I'll be returning the two video cards I bought.
you guys getting nvidia hardware acceleration + dual CPU + RT working?
not a chance in hell =) at least not for me
heh, ok, noticed a bit of noise in here about it, I"m running dual 1.2Ghz Athlons + 1 vid cards (1 AGP, 1 PCI)
hrm, must be on another server
er 2 vid cards
AXIS still runs fine in sim mode though
bytecolor: there was a dual processor rt kernel built - but it was found to be not 'viable'
They want a 1 kernel 1 kill :)
and the dual rtai kernel didn't support single processor computers well.
imo it shouldn't have to
just like a quad kernel shouldn't support dual cpu
but then they have to support different builds for different rtai kernels
the way I understand it
each different variation increases the work of the linuxcnc release manager
would that be you?
no, that would be cradek
please everyone, feel free to build a custom rtai kernel for your own machine, and build emc2 from source
jepler: nice pictures.
I just can't do it for everyone
skunkworks: thanks -- it's only the tip of the iceberg
jepler: I bet
how many gigs?
cradek: Heh, the last time I compiled anything was circa 1980
skunkworks: actually only 900 megs, about 600 photos
Guys where the link to figuring emc for my machine?
for the dual processor?
mschuhmacher_ is now known as mschuhmacher2
no,no, can't use that for emc, just for things like period, my leadscrews, etc
there is pdf documentation available in the same menu where you launch emc

Ok, if my ovl max is about 18000, what is a good BASE_PERIOD ?
at the bottom is a open office spreadsheet that will calculate what you need.
[20:16:41] <Jymmmmmmm> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TweakingSoftwareStepGeneration
200ns == .2 uS ???
step length and step space?
length being duration?
and space being time to rise?
never needed to use it - you would have to look at the emc manual
thiese are from the spreadsheet
Required Step Length Required Step Space Required Direction Setup Required Direction Hold Worst Case Latency Recommended BASE_PERIOD
the DIR values I got from the wiki, not sure what they are asking for for the STEP values.
skunkworks: do you know who wrote that spreadsheet?
* skunkworks hasn't used it
jmkasunich: jmk-solo you alive? it's past noon =)
Ok, I'm reading this http://www.xylotex.com/XS3525V202.pdf
and I'm trying to figure out what the spreadhseet is asking for here.
in respect to STEP LENGTH and STEP SPACE
JymmmEMC: it's quite well explained by jmk here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?TweakingSoftwareStepGeneration
thats where I'm at, but the nomeclature isn't the same
This is the closest I was able to find: http://126.96.36.199/search?q=cache:xjDJ595K9_cJ:wiki.linuxcnc.org/cgi-bin/emcinfo.pl%3FStepgen+step+space+site:linuxcnc.org&hl=en&ct=clnk&cd=1&gl=us&client=firefox
alex_joni: I'm just trying to enter in the proper vlaues in the spreadsheet, but I'm not sure what it's asking for for the STEP values.
JymmmEMC: C and D are the step length and space
jepler: AH THANK YOU!!!!
Ok, besides glxgears, is there something else I can use and abuse to get a higher OVL AMX latency in RT Test?
so far I'm at 15115
disk IO, usb IO, network IO maybe?
drag some windows around too maybe
Hey - look what I found http://www.electronicsam.com/images/KandT/xyz.txt
already did the window dragging.... have a browser, pdf view gaim, gimp running, will try cd
that brings back memories. (trying to write my own machine controller in basic) about 1989
that was, a while ago
skunkworks: that's kinda cool, I might try that out just to see/kearn wht it does
if you uys have 2k or xp, I have the GWBASIC if you want it
I think I was using fastbasic or something like that - don't remember the name - but it was compileable
ah, no idea
(needed to be to run fast enough)
Is this an actual controller, ?
QuickBasic? precursor to VB
ds3: oh gawd yes
MS-DOS 5 era
Not q basic... I don't would have to look.
skunkworks: this thing reads gcode?
Yes it did (look at the last few lines of the program)
It was pretty rough
* JymmmEMC grabs a DVD+r and tries to use/abuse latency
maybe it was quickbasic. I really don't remember.
skunkworks: Okey, very cool. I can learn from it, and the math too
ah - I was just winging it there.. I don't think it was the best way to do things... plus it was pretty basic.
used sin/cos to do arcs...
I quit working on it when I tried to figure out how to do read-ahead and got a head-ache
Hey, I don't do C, I dont do python, I dont do trig.... BASIC (pun intended) is a good thing to learn from
hmm - I think I used firstbasic
it would be considered ver .0000000001
looks like I had g1,2,3 sort of working.
these days, you'd be better off with Perl than basic
it even has $ symbols in front of variables, to make basic users feel at home
it's c/c++ for me!
well yeah, but C can be a bit spooky for basic users
yeah, but with a little learning you can do so much better...
Perl is nice and friendly, lets you get away with a lot.
hmmm, the perl I've seen and written can be as cryptic as all get out.
so can C
regular expressions and all
it is a lot harder to SEGV in perl then C
you're right. I forgot what perl I knew
I just want to understand the inner workings of motion control
get people here to ditch python and move to perl ;)
* ds3 runs and hide
Jymmmmmmm, in that case, learn C
haven't learned and python yet, haven't had to and don't see what it offers over c
C++ was worhtwhile, and Java
robin_sz: With basic, I dont have to let the lang get in the way of the operation
may need to if I want to learn the Axis code
Ok, it looks like I can set a BASE_PERIOD to 17.12uS
Jymmmmmmm, to learn the inner workings of CNC you will need to study soem CNC code ... either that means you already have a good cnc control in basic to study, or you will have to look at one written in C/C++
robin_sz: Eh, consider what I want like "reviewing" a college class.
well, let me consider again your stated aim : "I just want to understand the inner workings of motion control"
the only real "documentation" for that is the code
I said understand, not know
if you cant understand the code .. then, shrug, I guess you'll have to find someone to translate it into english for you
robin_sz: Yes Dear
well, run along now. let us know how it goes.
robin_sz: Yes Dear
bah, how do you do ignore in xchat?
I think I might buy this: http://apex2.apexauctions.com/auctions/50089/photos/gallery_20_3.jpg
what is it?
good night all
a distro really sucks when the least painful thing to do is to download gcc from ftp.gnu.org, compile, and replace the supplied gcc
* archivist guesses debian
nothing else has been so bad, ever. even SLS was less painful then that
cradek, 2000mm wide, 50 tonne CNC press brake ... for bending stuff
archivist, thats fairly trivial in debian .. just apt-get source <package> and then dpkg --build-package
cradek, I have one already, but its workign flat out all day, every day .. so time to get another, and that one is a *nice* one
things should be trivial in debian yes, but not always
well, getting and compining packages is
ds3, I know fc6 is a bit painful, but I thought it shipped with a sane kgcc to replace hte braindead one that masquerades as gcc
looks like your choices are gcc-4.1.1 or compat-gcc-34-3.4.6
(on fc6 using the regular fedora packages)
but fc is all about adopting technologies that aren't quite ready yet
what's wrong with 4.1?
that I don't know -- I assume ds3 does know what makes it unsuitable for him
it barfs on old code; I have a fresh gcc from gnu.org and that part compiles
In respect to INPUT_SCALE, I have 200spr steppers, 8microstepping, and 10TPI leadscrews. So, 200*8*10= 16000 ?
direct drive I assuem
Well, the XY are 5TPI ballscrews with 2:1 gearing
Z is direct
I KNEW I should have plugged in the header last night, brb
the developers of gcc 4.1 have adopted the idea that it should meet the c++ standard
the standards committee recoils in horror of the idea
gcc being c or c++ ?
always forget there is a difference
Eeeeesh that always creeps me out.... axis.ngv just stops at the last point, but I think that the machine froze up!
In Axis, is "Touch Off" "No I don't care where you think you are, you are really here"?
Ok, cool. I'm so used to TurboCNC, just tyring to find the equiv in Axis
Well, running chips (spindle off) right now
I think you will be pleasently suprised :)
Well, I'm a keyboard control freak, so....
Nothing againest any of the guy's doings of course.
I was surprised to find that I can rotate the axis display w/o something mucking up
that is the magic of realtime :)
DOS is realytime, but well you know
I was surfing and editing gcode while running parts. Bit scary
I'll use the laptop for that on it right now)
dos is only realtime because you can only do one thing at once
just disable interrupts, and see how realtime it is
you could do that in a user program
Now I gotta see where pushing the envelope for my machine is.
Jymmmmmmm: that is the fun part :)
disk access used to be the place where things went to hell
I tried accessing a cd, ovl max stayed at 15000ns
the realtime guys fixed the hard drive delays first thing
bill gates still hasn't figured out how to do that
In axis, is there a go to this position?
other than mdi I mean
mdi is the only way I know
did turbocnc have a way?
other than mdi?
yeah... ALT+G (after selecting the axis)
ALT+E was like touch off in axis
alt-g then you type in where you want to go?
for that axis?
Yeah,a lil dialog popped up, you ented in the coordiants and hit enter
neg value for left, pos vlaue for right, etc
never used it. (started using turbocnc)
oh - reletive?
skunkworks: Well, I dont have home switches
so everythign was relative
but depending on where I mounted stock on the table, I'd set 0,0,0 to top of material, bottom left corner
