SWPadnos: my simple machine now works under 2.1.7 and -trunk. thanks again.
excellent. you're welcome
I ordered my Seig X3 mill on Black friday last year... got it like DEC 10th IIRC (delivered to work)
I just brought home the last 2 major castings...
Skullworks-PGAB: Remind me to never have you to pick up something for me ;)
I been doing way too much OT - "all work and no play makes Jack a dull boy"
rum and coke..
Skullworks-PGAB: but couldn't you have just brought home a handful of parts each day?
skunkworks: Never saw the shining hih?
skunkworks: Never saw the shining huh?
actually I can't even say there here yet - as I've been to busy to drag them out of the car yet...
Shining = hardcore cabin fever Colorado snowbound style.
I broke the machine down into 5 major groups - the last 2 were the base and column.
ho ho and a bottle of rum!
no rum - SoCo
way too sweet
and rum isn't?
Not where as sweet as SoCo
No where as sweet as SoCo
But I haven't touched SoCo since I discovered Tequila decades ago
I think I finally fixed my Z amp faults!
I swapped Y and Z motors (this sounds easy, doesn't it?)
nice. what did you do?
the problem stayed on Z
so it's not the motor, tach, amp, or encoder
this leaves wires and connectors
and switches, if they're connected to the amps
so I messed with (scraped off, tightened, etc) all the wires and connectors and now it works
switches don't go to the amps
one remaining problem which is already determined (a failing power supply)
I think it has a heat problem
the 5v sometimes drops to 1v and then slowly comes back up
I'll tear it out and use an AT pc supply (AT because you can wire them to actually be on)
you can do that with ATX as well - I think you just connect the purple wire to any black wire
or it's gray or something - the power control goes to ground
I don't believe it :-)
cradek: don't know what voltages you need, but maybe you should be looking for that +5/+12V supply taken out of the scsi enclosure you gave me
of course, the other one is probably the 2A to 5A 5V standby wire, and you don't want to ground that one ;)
jepler: I think it's +-5 +-12
cradek: ah forget it then
oh, it's the green wire
gray is power good and purple is standby power
iirc I had success hooking the enable to gnd with a 1k or greater resistor, which means getting the wrong pin isn't quite so bad .. not sure if that's in spec though
it probably is
so could a smart person (not me I bet) make a thingy that plugs between the PS and MB that causes the machine to reliably always come on?
you should be able to stick a resistor in the back side of the ATX connector and get that to happen
(can you tell I hate these modern soft power switches?)
I dunno; I'd design the BIOS to freak out if power was applied without being requested :-P
and it might not even prevent the motherboard from shutting itself off, which would be a good thing
I think the freak out table is full on most BIOSes
but the power supplies themselves are a lot more useful, no minimum load required nowadays
awallins site is so nice. he has plans for an opto-iso card set for the m5i20. http://www.anderswallin.net/2006/08/optoisolator-cards-for-mesa-5i20-servocard/
I found his site through R/C airplanes too. I knew I recognized that name
sf.net pages load about 50 times faster in dillo than any other browser. makes a big difference here
at 350KB I'd hope so =)
i think its because it doesnt load all the .css crap
and of course its naturally faster at everything else
No, I think it's still loading CSS, just not so much overhead as all the DOM/JS/JAVA/ plugins etc
I really hate that browsers need 60MB ram minimum
if dillo had some minimal css support and opened pdf files correctly i'd use it a lot more
PDF has always been a plugin
you can make it link externally
it doesnt download them right at all, and you cant configure how it opens them
ah, gotcha. I saw that the project is frozen till they get money too.
hm. i use some fork that has antialiased fonts
so i guess someone is still working on it
Ah, it has the minimalistic international stuff, that's probably the biggest thing.'

I'm so bored I'm watching Torchwood Episode 1
Skullworks-PGAB: How come?
trying to wind down - have to be up for work @ 3:30 xcan't sleep
yeah - part of the promotion - new company deal - I'm back doing 12's for the next few weeks
now I have 28 machines to woory about
did you get a raise?
fat checks - take them home - open them up - read them and fall asleep
what time is it there?
oh your an hour ahead of me.
your in Norcal?
i"m in central colorado
you might as well stay up, then take a big nap at luch time
our plant boarders COS airport / Peterson AFB
is that on a timeline?
I'll sleep tomorrow nite
Yeah no dont, so might as well guzzle all the coffee you can now =)
Yeah no doubt, so might as well guzzle all the coffee you can now =)
na - I can still catch a few zzz - plus I have duall alarms to get me up...
that works, not for me though =)
yeah - I need 2 alarms - or a electro-shock unit to get me up
that MIGHT start waking me up
I used to sleep thru my roommate firing his paintball guns
alex - does the wiki support tables?
the wiki - wiki says it can if the proper plugins are installed
toast is now known as toastydeath
we are perpitrating serious business
does anyone know anything about auditory imparement, either physical or neurological
i read some stuff about flanagan's neurophone
it looks like i can get up to around 512 lines on a 50mm encoder disc with my 600 dpi laser printer
but 256 looks a lot better
get ugly moire patterns with 1024
why is that funny?
i'm not entirely sure
but i did actually laugh
why not just use steppers?
they're no good?
anonimasu: dont you want to learn how to program in postscript?
there are more fun things I could do with my life..
like hammering nails into your legs
so guys, i can hear people make sounds
but i have a hard time figuring out what words those sounds are
in general, or just now?
it's an ongoing problem
i hear pretty darn well
small noises, etc
is there background music?
but when people speak somewhat softly, at a volume other people can carry on a conversation
or during a few other situation
i can hear all the noises they're making
but i can't figure out what words they are
i can hear the group of sounds that is my name very well
I guess I better get to work
and that makes me turn around and ask them to repeat whatever it was
I got a phonecall off someone while half in the shower
that means that I had just taken off my socks
damn them ^_^
make sure you get paid extra for showertime
can anyone tell me if this is gray code or not? http://fenn.dyndns.org/pub/irc/encoder-panelized.ps
it looks very much so
i thought it would be more complicated than that
you just rotate each ring 1/3 the previous segment width
how do you parse it?
err what do you read it with
a cmos sensor array?
that's a 10 bit disc right?
i'm not sure how professional absolute encoders are made
it's missing the first ring, will fix shortly

i wonder why ring 4 is not lined up with the rest
Um, someone already created that a long time ago
yes jymmm i know
unfortunately the bastards didnt make it easy to find
fenn: reinventing the wheel, literally?
because i cant find it
btw anonimasu that large encoder is binary i think
well, a messed up binary
fenn: You coulda just asked.... http://www.nccabq.com/Network%20Trash%20Folder/2inch-45degree.ps
that's not the same, actually you got that from my wiki :P
no, from the logs
it uses a pseudo-random sequence in the outer ring, and the code is a lot harder to figure out ;|

emc2 could do that.. :)
I wouldn't want to be the person that had to set up the HAL for that though
unless it was just for fun, you know - like a vacation or something ;)
or write the rev/forward kins for the milling operation..
that's not a very big deal, except that it changes depending on which chuck is in use
also, there are multiple "spindles"
whereas EMC has only the concept of one spindle
I was thinking setting up normal lathe xz then use 3 other axis to create the milling operations. but I may be looking at it too 'big picture'
now that's funny. I get a call from "TD Banknorth"
I say hello, and the person says "hi, is this TD banknorth?"
so I say "no, you are"
and she doesn't know what to say
I guess she was trying to call another branch and just had the wrong number
there are so many weird users out there
hey - I am not that weird.
one of them wants a bunch of new features:
g-code scaling in the controller
speeds in mm/sec
they could do speeds in mm/s using pyvcp..
or does he want to enter the feeds that way?
(isotropic) scaling and/or rotation might be nice but I don't want to do it
We talked a while back about scaling didn't we.
yes it's one of those things that keeps coming up.
I think arcs cause some issues.
yes that's why I said isotropic
Easiest way to scale that I've found is to change ini
heh - I find the cad software the best for me..
I remember trying to do a rotate on a fanuc controller - after goofing around with it for a bit - I finally figured out it wasn't a purchased option.
I think the main point of rotation/scaling in the control is to align a program to the actual mounted part
yes - you could do some neat things like - probe 2 holes and have it align the program.
or 3 to get X+Y scaling
could you write kins that would take a rotation, offset and scaling input?
you could.. problem is passing the data
I mean how to specify what kind of rotations, etc
I am sure I have not thought it thru all the way ;)
neither have I.. stopped at what seemes the first hurdle
* JymmmEMC hands alex_joni a step-stool
need those sneakers with springs in them
SWPadnos: You get built in wheels or nothing!
I have seen so many kid fall on their a$$ with those on. :)
I hate those
SWPadnos: You skater-hater you! ;)
I have a kernel update, but whenever I update it always resets my grub file. Is there any way to prevent it reseting my custom settings?
you need to put your magic settings into the default line they have
I don't remember what it's called, but it contains "splash" by default
(which you can't just remove, you have to change it to "nosplash")
MY custom settings are: nosplash verbose vga=791, but they get reset upon updates
right - look for the line with default_options or something like that
and change those
then new kernels will get those options
it's called defoptions
here goes nothing
do the defoptions apply to the recovery menu items too?
I bet they don't
only because the recovery lines don't have splash, and that's in the defoptions
that's in altoptions
This is ubuntu.... they install the sound drivers even if you don't have a sound card.
I tell ya what though.... oBSD it a huge reality check =) You think you know something about nix.... forget it! LOL
Ok, reboot. brb
Nope, that wasn't it.
shhh - he is back
JymmmEMC, it doesn't change the settings for already-installed kernels, it changes the settings that will be added to new kernels when you install them
skunkworks_: I love you too ;)
SWPadnos: And guess what.... I booted to the newly installed kernel and it went spalh on me =)
it's possible that removing all options from an installed kernel will cause the default options to be used
sure, but had you installed that kernel before editing menu.lst?
SWPadnos: Eh, I think that ununtu does something funky. No I installed the new kernel AFTER you gave me the defoptions thingy
There's mention at the top of the menu.lst file that says about keeping settings for next update, but I dont get what it's saying.
you did leave the # in front of it, right?
I think you're supposed to
in the defoptions?
that's a comment to grub, but a command to the installer - the ## are comments to the installer
yes - # defoptions =my special options
note line 56 (or thereabouts): DO NOT UNCOMMENT THEM, Just edit them to your needs
that's not big enough
That doens't make sense. A comment is just that, a comment (excluding the 1st line of a shell script)
that setup is asinine
it works, once you understand it
yes, lots of asinine things are functional
the other option is to have another file that provides the metadata needed by the installer
whee.. lots of castles in france
alguno conoce de una buena fresadora que se pueda construir con poco dinero?, somebody knows a good cnc mill project that i can build with little money?
Ah, I think that specific section is only read by the debian update-grub script, not actually used by grub itself.
JymmmEMC, exactly, that's why it's got to keep the # - that makes grub think it's a comment
cyborg_ar, nothing springs to mind for inexpensive CNC kits
SWPadnos: Yeah, but I was editing the section WAY about that with the defoptions
SWPadnos: thus the cobfusion
cyborg_ar: look at http://www.cnczone.com/forums/
for ideas. there are a lot of inexpensive ways to build cnc machines - depends on what you want to do.
I like mdf and drawer slides ;)
cyborg_ar: cavet empor
I like Bridgeports ;)
skunkworks_: did yo ever build one using drawer slides?
SWPadnos: shush you!
cyborg_ar: I don't have any personal experience with this machine, but it might be interesting to you: http://www.instructables.com/id/EXME02SF4WY1JJW/
skunkworks_: Actually, Les said you could use one linear rail, and float the other side
that is similar how our big gantry is built.
skunkworks_: But, I do have a stack of bearing slides here I'd like to try out someday
cyborg_ar: here's another one I have seen on the internet, but don't know much about: http://liutaiomottola.com/Tools/CNCRouter.htm
JymmmEMC: it has a linear rail and leadscrew on one edge. It sucks. It really needs atleast another lead screw on the other side.
cyborg_ar: NOTE: *if* you do decide to try using skate-bearings on a 'V' shaped track, be sure to: a) make them PERFECTLY aligned or, b) Have some way of adjusting them.
skunkworks_: Due to the floating aspect?
i was thinking to use old dot-matrix printer's rail
cyborg_ar: oh, you want to make soemthign tiny?
jus to try the power of emc2
JymmmEMC: it shakes too much at higher speeds.
cyborg_ar: You might consider ebay for an XY stage
SWPadnos: ever seen lego mindstorms?
[18:48:06] <cyborg_ar> http://www.instructables.com/id/S8JUKR6F4WY1JKE/
<- that looks great, but i think i should use the printer rail or drawer rails
alex_joni, never in person
alex_joni: sold mine on ebay a few years ago.. It was pretty cool - I used the C programmer someone had made up. it had like 8 tasks that would run at the same time IIRC.
I see the newer ones seem to have servos.
ok. breakfast time. bbiab
* cradek loans this poor guy a drill press and center drill
and a band saw
and a vise
does that loan include a few days of instruction? ;)
and a tap handle
and an automatic center-punch
and tapping fluid
skunkworks_: I just played with one with servos
3 servos & 4 sensors in a box
+ usb + bluetooth
Sigh, I still want a CO2 laser (100W would do)
JymmmEMC: I hope you realize how much 100w of laser is
anonimasu: price wise?
anonimasu: Ah, yeah... just for plastics/wood
anonimasu: I found a complete 60W (40W ?) CO2 laser with a 28" x 50" travel and full controls a la paraport for $6000 shipped.
anonimasu: I'm just *REALLY* chicken to TT $6000 to China FOB
I'd rather they ship it into the US (thay have an office here), drive down to the docks in LA, they hand over a cashiers check.
It's pretty crude... You have to solder the laser to the machine. But I can deal with that.
skunkworks_: really cool
SWPadnos: guess how you program them (lego mindstorms)
microsoft robotics studio
isnt that some mod
well.. labview based
heh, it's a gui thing they have with function blocks..
ah you are right :)
I just programmed one the other day
but otoh you have C API
and you can do whatever you want
what did you do with it?
Fucking SOB... http://www.thelgnews.com/article/2007-1-26-ca-cold-duck-case
I swear, I here more stories of bizzare animal cruelty in this area, than anywhere else.
Could someone please remind me WHY murder (of humans) is illegal?
JymmmEMC: because humans pay tax
They can keep their money, no need to pay a dumbass tax
JymmmEMC: well, I gave you a answer.. :)
pretty shitty one at that
JymmmEMC: it certainly isnt because some humans are essential so society..
I find it sad and pathetic that you can murder someone and get 10yrs, but steal $100,000 and you can get 20 yrs.
(just had to vent is all)
Just got a nice suprize, ups showed up with the ER 40 collet set r-8 and mt3 holders. I can't belive 800Watt's shipment got here before the geckos... guess I may be lucky after all
skinnypuppy1334_: that is lucky! hey, tell me how the collets look :-)
cradek, the collets look nice, I'll put a dial on them later... but the box isn't suitable for transporting a sofdt turd
skinnypuppy1334_: I have an ER40 set but it has one missing and a few are kind of screwed up - I don't know whether to buy one of his $70? sets or buy the ones I need from enco at $2x each
isn't 15 arc minutes .25 degree?
[20:07:52] <skunkworks_> http://www.cui.com/amt/ASIC.pdf
so - 2048 resolution encoder has an accuracy of .25 degree - that would be in effect 1440 line if I did that right
cradek, I'm going to play with them tonight and put the test dial on them in the spindle. I'll see how the taper bore seat is on TIR and the TIR of various tools in collets .
skinnypuppy1334: cool, I'd be very interested to hear what you find
[20:09:50] <skunkworks_> http://www.amtencoder.com/
I had planned on making some more er40 holders on the haas sl20 at school and use a setscrew to hold some cnc tooling to keep the length offset the same
you mean like a regular collet but with a setscrew and no expansion?
Yep, just reamed to the tool shank od and setscrew into place.
that's an interesting idea
Yeah the next best thing to a toolchanger would atleast be tools that will keep the same length, I don't have a variable head on the mill but a step pulley so its likely I'll be changing pulley steps anyhow at a tool change.
skinnypuppy1334: tool length sensing!
skunkworks_: it explains in the paragraph right above the table
??? which paragraph is that?
sub-resolutions ... rate multiplier ... retain the accuracy ...
the high ppr is an illusion
lunch is doubley so...
well that quote was a bit off 'Time is an illusion. Lunchtime, doubly so'
the low-end usdigital encoders have a quadrature error of 60 deg e max. For 300CPR that's 12 arcminutes, not too different from the claim in that pdf
[20:35:17] <jepler> http://www.usdigital.com/products/aedr/body_index.shtml#encoding
so if the price on the amt resolver/encoders is good I'd try it
but I wouldn't expect miracles
what the heck is e?
they are $29 from digikey
skunkworks_: "electrical degree" - it refers to a 1/360 portion of one cycle of the quadrature signal (as opposed to a real degree which refers to a portion of one cycle of the physical encoder wheel, or which has no meaning for a linear encoder)
ok - confused - wouldn't it then be 60/360=.1666 of one quaduture cycle?
so 300cpr*4 = 1200 edges - 360/1200=.3deg*.16666=.05 degrees
