andypugh that drill vise you ever notice how as you tighten work in it the work moves?
it drove me nuts how work would never be square to the fixed jaw
least on all the drill vises i have it always cocks up as yo utighten it down
I always end up touching-off to the moving end, so haven't noticed
andypugh well I'd notice indicating vises to my mill table
the more I tightened the pice I was indicating the more I'd see movement on an indicator
And I did replace the keeper plate with 1/4" cast iron, then blued-and scraped that to the underside of the vice...
try it snug a piece up with an indicator on it its screwy
all I'm saying is it has been an issue with me doing some stuff
It cost £10, I can't be too critical.
I have a couple of better ones, but they don't have the capacity.
the round stock trick can help though
you know put a big piece of round stock on he movable jaw side when you tighten?
I just tend to tighten it then whack the work down with a hammer ;-)
I am used to working with tired old machines and tooling, I tend to make all dependent cuts at the same set-up
for me its a challenge just to make stock square
I tend to square stuff up in the 4-jaw chuck on the lathe.
(Stuff that will fit in the 4-jaw chuck, anyway)
when i made this I got fussy with some parts being square: http://img191.imageshack.us/img191/1184/headstock.jpg
If you look at http://picasaweb.google.com/bodgesoc/Gibbs#5403345449585651218
you can see that's how I squared-up the ball-nut mount.
one of these days I'll get a decent lathe i could use one
Yeah, I can see that being non-ideal for squaring up blocks of meta.
Did you buy that one, or make it?
todays doings: http://vimeo.com/10139114
andypugh I madei t out of all structural steel
(I ask mainly to judge how rude I can be about it)
you know angle channel
I learned the legs on hot rolled 3" C channel aren't exactly perpendicular to anything
evne though they look like they are
Considering how they are made it is perhaps surprising that they are even close.
andypugh you can say what you want to it works
I am a little concerned about the thrust capacity of your headstock bearings.
One of the most important realizations to a machinist is "nothing it square." Only is it good enough
yeah i need a bigger spindle i know it was what I had laying around
clytle374 if its withn a thousandth or so it's square to me!
clytle, shhh, that's what tolerances are for :)
We dismantled and threw into the back of the storage heap my dad's woodworking lathe a few months back. It was a conversion to woodworking of a metal lathe previously converted to Cam-milling for the Phelon and Moore motorcycle company.
andypugh how i got thread on that spindle was something else it was hard to get it concentric without a real lathe to do it on it took me 3 tries to get it pretty good
P&M !!! a real relic
Indeed. That's why it went on the storage heap, not the scrap.
Anyway, time to bring to a close a singularly unsuccesful day.
thanks all, for the help. I've founf a 74HC14 in my parts bin, so Im off to make a duplicate encoder :)

well it is getting on to being bicycling season now
there is no slow season for biking.
dont forget the southern hemisphere
there is here.
I don't like to bike in the cold
more like the non biking season
we arent the only country that rides bikes
we are half of the worlds economy though
and lots of bike nuts work on their stuff in the winter
not me i park mine in my leanto
ehh, i've sold just as much stuff overseas than in the US
the british and austrailians are big spenders when it comes to bike stuff
I got an old Nishiki frame I salvaged from the dumps I want to build up
single speed it!
nah i have an old sugino aero mighty crankset I want to use on it
can we work for you when we get outsourced?
no, it's a one man operation
I got into a bicycling accident years ago and didn't realize at the time how much damage I did to that bike
so I have all the parts off it except for a few
single speed it. dont be a wuss lol
the few that got bent
I'm 45 i can be as big a wuss as I want biking now
hey when I was young i was superman on a bike
I didn't know it at the time but I sure as hell can't ride like that today
but when i got into that accident I didn't get back onto a bicycle for years
some guy made a left hand turn and i hit him
I did a somersault over his hood
a tree did that to me a few times
and bent my bike when I hit the curb in 3 different places
yeah i was pretty damned dazed after it I didn't realize how much I'd messed up my bike
yea i bed
it was funny I looked at the curb to see if I'd cracked it with my skull or not
* pfred1 is part German ...
I wish I had video of that accident I'd be like one of America's stupidest people today or something
I must have looked like ET when i was flying
I did a total rotation over his hood I can't imagine what he was thinking
like oh my god i just killed a kid my life is over
i did something similar on my motorcycle... some lady pulled out in front of me when i was doing about 45-50mph
oh i was hauling ass I always did back then
I mean I must have been moving to have flown the way I did
numne is now known as numen
it was at the crest of the steepest hill in town.... the 2 cops across the street who saw it said i flew as high as the power lines
the farther i flew, the higher i was off the ground
because of the hill
when we used to go to the GP motocross races they'd jump that high
did the hill help out on the landing?
i landed on my ass, i had a bruise the shape of my wallet
clytle374, it must have, i didnt really get hurt
thought so, people don't usually take falls like that without gear
i spun her car almost all the way around and up an enbankment. it almost flipped
I wasted my rear chainstays my front forks and my front rim when I had my assicent
it was a chrysler new yorker
clytle374, I was wearing leathers and a full face helmet
That helps quite a bit, but still lots of you unprotected.
how does a helmet help you when you land on your ass?
pfred1, do you think you sit still when you hit a car going 50?
i tumbled a bit when i landed.
took one of my boots off, it was at the bottom of the hill, along with my battery
I got high sided at 60 about 7 years ago, got some good height on that one.
I was probably doing about 25 and I was in toeclips and I held onto the handlebars too
i saw the cops running towards me when i was flying through the air
I did too i mean I somersaulted over the guys hood!
it was kinda freaky
me and the bike
near death usually is
nothing but air
if I'd have stuck the landing better it'd have looked like I knew what I was doing or something
clytle374, all i got was a little bone chip in my wrist, and i was sore for a week or so. i didnt even get knocked out
but then I got a mountain bike out of the dumps and fixed it up years alter and started riding it
then i was at a garage sale and some guy was selling a really nice Teek touring bike so I bought that
My biggest injuries came when the bike caught me.
Luckily a gsxr1000 isn't a heavy bike
clytle374 bullets aren't heavy either but they can do some damage when they hit you
400lbs can do some damage
I crawled away
some of the stupid stuff that has happened to me has convinced me that we really do die when its our time and not before hand
then, and only then
I seen the damnest stuff kill people too
* JT-Hardinge wonders how I can check my index pulse on the spindle to see if it works
can you look at it in halscope?
thats what I was wondering but I don't know anything about it
JT-Hardinge, how about hooking it to a latch relay in ladder or something, and hooking that to an pyvcp led?
what are these pyvcp leds? I don't remember them in the manuals
it's a fake led on the axis gui that you can hook up to pins
look in the pyvcp section of the integrators manual
Danimal-office but if you had an LED screen it'd be a real LED!
Dan I'll give that a shot
JT-Hardinge, not sure if it'd be too fast for ladder to register, but i wouldnt think so
I either buy a parallel port board or i build up a whole other junk PC here to test out my port buffer board on
just spin the spindle really slow by hand maybe
because i sure as heck ain't testing my project out on the PC I want to use for EMC
a singlespeeder would.
Danimal-office I would but I don't like my beer watered down
from crying into it!
is it a nice pc?
its as nice as i have to throw at EMC right now
i think the pc in my mill i got out of the dump
if i buy a parallel port card I cna always use it for more inputs and outputs if I don't burn it out
oh this is a dumps find
there ya go!
but i don't find too many P3 1 GHz systems
yea, the one i'm using is an asus mobo with 1 gig of ram and a amd athlon xp2800 processor
your dumps are better than mine
the one i just replaced in my mill was a 1.4ghz p3
I ran one of my motors in the stepperconf axis test and it seemed to run it as well as it was going to run
pictures of the bike i wrecked: http://img.photobucket.com/albums/v20/danielwilcox/IM000267.jpg
hmm, I can set the spindle index enable signal to true and spin the spindle and it goes false showing the index works.... so what did I miss

[01:57:01] <Danimal-office> http://img.photobucket.com/albums/v20/danielwilcox/101635.gif
Can you view the values of floats in ladder?
skunkworks, i think there's an s32 to float converter or something... maybe the other way around
JT-Hardinge: I thoght that's how you always ride... probably slowed your as down from 140MPH
the KZ would not do 140mph as I recall
JT-Hardinge: Yeah, cause no sproket =)
skunkworks vars button twice then type in the one you wish to monitor
I think :/
JT-Hardinge: Didn't you take the full dress up to 150 iirc?

JT-Hardinge, the dyno sheet from my 954rr: http://img.photobucket.com/albums/v20/danielwilcox/dyno.jpg
71.9ftlbs of torque
not too bad for a 370lb bike
of course they're a bit faster now i guess
mine is close to 800lbs
they're still fast though! i've ran with a few gold wings
this is me http://i47.photobucket.com/albums/f163/johnplctech/hunting/P1010063.jpg
the 1800 is real fast
nice, did that deer make it into some jerkey?
ok, index enable seems to work
my 954 would stand up doing 90-117 in second gear just by rolling on the throttle slowly
what is the confusion I wonder :?
(i hate wheelies)
what is it connected to?
everything it is supposed to be I think
wheelies was my favorite thing till I busted a gear in my Honda 300 Dream!
cant you just copy the configurations of the x and z axis, but replace the axis with the spindle?
JT-Hardinge, it freaks me out. i like both wheels on the ground
Danimal-office I don't even like convertables
I used to ride my 10 speed around the block on one wheel but not any more :)
lol i drive a convertable
motorized I'm into the whole capsule experience
last time I tried that with a stunt bike I busted my ass
at that point I removed wheelie from my vocabulary

I need to figure out what the problem is with threading
i dont have one
I'm just missing something I'm sure
using all the proper g codes?
maybe try one of the examples?
Just hangs out waiting for the thread start?
using the g76.ngc example
like it don't get the index or something
did you look at some lathe sample configs to see if they're the same for the spindle index?
yea and the manual too
I can see motion.spindle-index-enable flash on at the start of the thread
is the spindle spinnding when it's just sitting there?
spindle-at-speed is on...
it's not spinning too fast for the axis to keep up, is it?
how many tpi?
with a 5i20 :)
so it should be going 40ipm, right?

* JT-Hardinge gives up for the night
cradek probably knows what's wrong
JT-Hardinge, is your encoder scale in the correct direction?
positive or negative
maybe it thinks it's going backwards?
It's only an index, right? If so, how do you get a direction?
it's got an encoder on it
a,b, and index
no other way to do threading as far as i know
if it thinks it's spinning backwards, it wont thread
I was wondering that.
maybe it isn't getting the a or b signals.
or they're reversed
but he says it says it's at speed
off to bed, good night

so you're ahead of me

i stick to women for that reason
how about a computer enclosure?
excellent idea. think I have a dead shuttle in the closet
but, I think it just needs a PS
wonder if they would fit in the emc box I'm using
buy a $30 case with a power supply in it, and take the worst of the 2 cases for the machine, and use the power supply to fix the pc in the closet
half the time you can buy a case with a power supply in it for the same cost as just the power supply
the shuttle is a tiny box with a miniature PS
good for a tiny machine!
nice form-factor for this though.

could i incorporate the output of a digital read-out onto my machine that uses steppers?
is there a way for EMC to make corrections if there is a difference in the stepper count and read-out values?

Good morning from germany
is ther a viewer for g-code in ubuntu karmic
no visuel the path
to view the paths the code takes you can use EMC simulator
thanks EMC is not on karmic so i have to export it to the mashine
ok so far so good
but i did this now for a eagle layout
and i god 4 lines at eatch objekt i want to have only 1
so where is the tool thickness on pcb-gcode
etching tool size
what diooes this mean
what does this mean
Diamater radius of the tool or ?
probably diameter if it mentions etching & thickness
tool size usually means diameter everywhere
thank you i found somthing in the forum -> make max lower then default trying no
ok back 1line now but so many lines missing
got it fixt default .1mm
mashine is milling
gaah i need a lathe to fix up my god damn leadscrews :/

when I do a g76 the lathe moves to the start position and I see the index enable flash on and back off but it just sits there
as far as I can tell all the hal connections are correct
any ideas on where/how to look for the problem
uh, are you experianceing the problem in the forum post?
Ok well just thought id ask the obvious.
grinding 5/8" HSS bits is tough
I should make a wet belt grinder for roughing.
pisses me off near the end of a grind when you get the tip just about right and it overheats because its too fine now
meanwhile less pressure will hardly even scratch it
and its allready taken the bite outta one $3 36grit belt
I allmost feel like making a bit holder for grinding or something...
but of course, then id be making a tool to make a tool to make a tool
and id never get ANYTHING done at that rate.

hello people. does anyone know how I could make alterations to the keyboard mappings in axis?
all I want to do is flip the directions for the left and right arrow keys.
turn your keyboard around :)
why do you want to flip them?
JT-Dev I was going to say pop the keys off and swap them
JT-Dev. Because I use a stationary laser that points at a table that moves....
...when the direction of +X movement is actually correct, its more intuitive for me to "Push arrow this way, move the table the other way".
you want the movement to be for the table instead of the standard way for the tool
you might try thinking about moving the laser not the table and it works out in your mind
yeah but you know how like you're in a rushed situation (like I have to get my hand under the table clamping it up) and I'd rather it was intuitive.
I guess it would be ok but if you ever try and run a properly set up machine you will just get confused again

you can look into axis.py 'bind_axis("Left", "Right",0)' but look carefully, there's inter-dependencies
owhite, follow archivist's suggestion, it does use the bind but the methid archivist posted has been reviewed
I needed that link to add extra jogs to mine as its 5 axis
tom3p: I will I'm just trying to figure out what function to bind to each key.
yeah its weird it doesnt look like the axis.py code has explicitly stated bindings to "Left" and "Right" keys.
well, it seems that Left and Right are just defined values, so you can overwrite them in the .rc file ( didnt look too close )
MattyMatt: that is a nice app, yertiz.com text 2 gcode. i have yet to try it but it looks like it can use any TTF font. I have been looking for a way to use the Halo font in my design ;)
but doesnt this mean they are both bound to the same value? " bind_axis("Left", "Right", 2) "
no it means the btns left & right are bound to axis 2
look at the func bind_axis
you will mess with what 'left' and 'right' are, like >< or +- or whatever as archivist 's post showed
let us know it it works

how the f*ck does one remove a broken tap?
frallzor taps are brittle so smash it out like glass
least when you're tapping steel that works OK
I use beat reamers
thru or blind hole?
just sharpen the end of a beat reamer to a point and have at it
ill have a go with a pin punch
frallzor its not magic and it doesn't work great but well there aren't many things that do for removing broken taps I try to work them out too by you know trying to get them to rotate counterclockwise somewhat while I am wailing away at it
so - doesn anyne have a good source for bulk 50pin ribbon cable?
I cant get a grip at it
so I need to bash it
so off I go to wreck havoc
skunkworks that's old IDE HDD cable isn't it?
frallzor: just curious, what size?
pfred1: no those are 40p
skunkworks: Dan told me about a place to get 50pin cable and connectors but I forgot where
could always peel the UDMA stuff
Jymmm 8-32 is a popular tap to break
so is 4-40 =)
yeah thats when you weld grind and try again
JT-Hardinge: this worked great... http://www.electronicsam.com/images/KandT/conversion/16io.JPG
there ain't no getting 4-40s out unless you have EDM
Note 50 pin cables are SCSI cables
Jymmm finding scsi cables today must be like looking for dinosaur teeth
So, I have a bazillion of them around here somewhere
skunkworks: it was Frys or something like that
I got a lot of ribbon cables scrapping various old mini computers some huge like 12 foot long ribbons in some of those
I have a bunch - but not that long..
I put the old style floppy drive edge connector on one end.. worked exactly perfectly to hook into these boards.
[16:21:34] <Jymmm> http://www.provantage.com/cables-go-02745~7CBTE01H.htm
skunkworks i know those connectors
skunkworks: What fdd uses a 50p cable???
it isn't - it is 34 pin. but works for the 16i/o card.
Jymmm use two they're small that's what IBM said for the first PC power connectors
a 12 1/4" floppy
I wonder how many motherboards got sold because of the two power connectors?

skunkworks: how much you want 500? 1000? 10,000? feet
I bet if you called them Jameco would sell you a roll
heh - I think 100 feet would do it - pfreds link is cheap
not really =)
Jymmm: you have cheap sources?
Jymmm but its rainbow ribbon
I bet the plain gray crap would be a lot cheaper
pfred1: get a flag to show your gay pride - it's cheaper
it just would be nice to make up the cables the exact length we need them
the plain gray is less than half the price

$60 for 100 feet
pfred1: that'1 1/4 the cost..... $2/ft rainbow VS $0.60/ft
Jymmm well in 10 foot lenghts it is a bit less than half what the 10' rainbow cost
skunkworks: probably can't beat that, and it's RoSH too
well yeah its PVC and copper
pfred1: you know that old china wire PVC is not RoHS compliant
although I thought the chinese put a little lead in everything ....
Yeah, I bet RoHS really screwed over a lot of china mfg's.
Jymmm RoHS is BS
how come the military and aerospace are exempt from complying?
pfred1: I could tell you, but I'd have to shoot you.
maybe because they generate a very small percentage of the lead in landfills compared to consumer electronics
cradek tell that to a radio man hit by a roadside bomber!
cradek all military and aerospace lead could potentially enter the environment
sure - but read again what I said
when I connect my external e-stop circuit to iocontrol.0.emc-enable-in Axis e-stop is controlled by the external circuit. Is this expected or did I not connect something?
I have no stake or opinion, but "it's BS" does not follow from "someone is exempt"
I'm guessing that iocontrol.0.user-enable-out needs to control my external relay too
cradek if rohs was so great then ther would be no exemptions
cradek especially for those who make the rules!
that's the same argument - I think it's still facile
pfred1: Sometimes LEAD is a requirement for a project.
cradek how can you defend you can't but we can scenario is beyond me
JT-Hardinge: that's one way it can work... not exactly how I prefer it though
cradek: how do you prefer it?
motherf*cking motherfu*ker of tap
poking estop reset in the gui brings it out of estop if the hard switch(es) allow it
frallzor: what material?
tap or steel?
but, either can put it into estop
i mean tap or the tapee
JT-Hardinge: unfortunately the only way I've managed to do that is with ladder
frallzor: the victim
cradek: ok thanks
frallzor: torch to heat/expand it a bit maybe
JT-Hardinge: there's an estop reset strobe from iocontrol that you can use to trigger a latching ladder rung
frallzor I've hole sawed sections out then rose welded in new material you know depends how important it is
move the hole ...
cradek: thanks I'll check that out
I could move but I cant stand that one side would be different from the other
I will rather die trying than move the bloody hole =)
frallzor these are all decisions we have to make on our own scrapping tapped in piece is an option too
scrappin the piece isnt really an option :P
since its the whole mill :P
what mills are made of steel?
I would say, many =)
huh? what is it?
but at least the tap isnt sticking out anymore
managed to kill it that much
oh it takes a while to break them out
it's there for good
even if you shatter the tap you won't be able to get all the bits out if it's a blind hole. you won't be able to continue tapping the hole.
frallzor: Just curious, were you using tapping fluid?
cradek if you can really get in there and clear the chip jamb that probably broke it they can work loose
ah, that's slightly better
what kind of tap? what size and thread?
cradek I use high pressure air
cutting tap, M8 coarse
and a face shield I hope
dunno about the terms in english :)
just guessing now
carbon steel or hss?
I would say its the worst of them
frallzor yeah the bust it out method only works with the hardest taps
I know it doesn't help now, but in the future, if scrapping the piece is not an option, spend a few more dollars on the tap
box didnt say what is was
the ones that fracture smooth
I dont know how much a proper one should cost, these werent cheap :P
cost isn't always an indication of anything
LOW cost is
some brand named "brooke"
cradek I've gotten lots of great stuff dirt cheap
its funny that if you remove an o from the name it spells out the result
frallzor you were hand tapping?
yes, but used a machine to do the first taps
frallzor what percentage of thread did you drill for?
30 holes without a problem and it just shatters
google says at least some Brooke taps are HSS
ah I got an extra
HSS it says....
use whats his name's trick and chemical etch it
I still say torch it to heat/expand it
wont it eat the victim too?
frallzor have you tried to clear the hole?
frallzor get all of the chips out of it
in that case, yes
frallzor: can you heat it?
We have drilled them out with carbide drills - but your setup has to be rigid
frallzor and when yo uwere beating the tap you couldn't get it to back out any?
nope, nothing to do that
frallzor: toaster oven?
Jymmm the pieces is 3x2m :P
frallzor: bunch of toaster ovens =)
frallzor: you dont have a propane torch?
I guess I have to continue beathing the shit out of it then and if that fails, new hole
frallzor what i use is a pretty small reamer ground to a point
does it seem cludgy to scale a number up in emc send it to ladder - do some math - then send it back and scale it back down in emc
that stuff is 150 proof - white (invisable flame)
can you tune velocity drives by setting the PID to 0 in the ini then get the best following error you can by tuning the drives?
off to try beathing the shit out with some pointy stuff
frallzor every little bit you break off clear the hole and try to get the tap to back out
they always loosen up
being as while you're beating it up you're making the hole in the work a little bigger too
frallzor: Try breaking up the TIP of the tap, not where it broke off
if pid is set to 0 - I don't think you will get output..
I think its a blind hole
I thoght he said a thru hole
yeah but if it's on the inside of a mill he may not be able to get to the other side
He did... 2010-03-14 09:48:37 frallzor: thru
oh he's got to be able to get it out then
I bet he'll be more careful backing off now
Or not use a tap for more than 10 holes, then replace
I was taping some stainless once and it was a nightmare
I ended up going for something like 25% thread and it looked like the shadow of threads in them holes but they held
you need a special tap for stainless
the stainless-specific taps work like night and day
Danimal-office yeah special strong beer tap
Danimal-office now you tell me about this special tap where were you like 3 years ago when I needed to know?
ah its OK I got it done
skunkworks: that must be why SWPadnos was telling me to make a square wave generator thing
but yeah it was like impossible to do I was breaking a tap every other hole
JT-Hardinge you want to make a square wave generator?
<SWPadnos>don't use PID in EMC, and just output a step change to the velocity command (I think that should show you the wobble in the amp PID)
[11:52]<SWPadnos>use a bare HAL setup with halrun for that
[11:52]<SWPadnos>else following errors get annoying
JT-Hardinge so SWPadnos is telling you that you have wobbly amps?
skunkworks: yep all zeros and it won't move lol
yea, they are held on with rubber bands
JT-Hardinge I think I'm starting to make the connection between rubber bands and closed loop systems over here too!
still having issues JT-Hardinge?
no, I just want to check the drive PID settings to see if they are set correctly
JT-Hardinge, is it possile that your spindle encoder is reversed so it thinks it's running backwards? or maybe a or be isnt hooked up?
JT-Hardinge would be what you're doing be called "tuning servos"?
a or b*
is there a oneshot in hal? You could set it up and output a off/on/off at some length. Trigger it - scope it - anylize it.
Danimal-office: the spindle encoder scale was wrong... threading works nice now
run that into the pwmgen
pwm input of the mesa card (might want to scale it so you are not running 100% ;)
just looking at the oneshot now
skunkworks like a scope triggerd sweep?
Danimal-office: you got it figured out yet :)
got what figured out?
how to make a oneshot => pwmgen :)
i dont know what a oneshot is
Danimal-office scope triggers on one signal then stops
I'm ahead of you then cause I just read the manual
no clue... never touched a scope in my life
as opposed to a clocked trace
f*ck brooke, the 2nd tap wont even tap
frallzor what percentage of thread did you drill for? also I like to champher holes i tap too
frallzor its almost like you get the first thread for free
I dont know what percenteage, I just use the drill intended :P
6.8mm for M8
frallzor well there are different drills you can use to get more or less thread
doesnt that require different taps too
no same tap bigger drill = less percentage of thread
if you're trying to tap more than 50% in metal its often a waste
well if 30 holes went along fine
I just say that the brand brooke is shit
could be your drill isn't drilling the same diameter now too
well the wasted tap I just have to forget, new hole and tap
what do you guys think of this logo i've been working on? http://img.photobucket.com/albums/v20/danielwilcox/hbcrev2.jpg
it looks nice
its for my bicycle parts company
I was going to say I have no context
I see the chainring in the C
why is the B lowercase?
just figured it made sense
years ago we used to bandy about the phrase HB but it didn't mean homebrewed in that context :)
throw back and forth
never heard that term
back then an "HB" was a "hair bag"
what's up HB?
just figured I should share that
it has several meanings i guess... first being they're made in my home, second is that some of my parts have bottle openers on them. lots of singlespeeders are beer drinkers.
yeah I remember tale of one old time velodrome rider that was a massive drinker
he was like the most famous rider of his day
i'm just waiting to see what my tshirt guy has to say about the logo. i think that will be the deciding factor
pfred1, i used to start each mountain bike with a beer, and finish with 20 lol
mountain bike race*
I'm curious why you equate your company with home brewed
I'd think you would want to project an image of precision or something
my reputation does that for me
I mean for mountain biking I get the dirt
If I have a milling head with an encoder and a 2-speed gearbox, does that seem like a good reason to run it under closed-loop speed control? (I am thinking of having LEDs in a pyvcp panel for maxed-out and "change down, you fool"
single speeders are all about custom stuff. they dont like retail stuff
then how about CBC?
the homebrewed beer thing fits singlespeeding
sounds too much like CBS?
Danimal-office I have the most kick assed micro brewery 6 miles up the road fro mme
trust me, i have a very good rep... noone is under the assumption my stuff is hack
Homebrew crack would fit single-fixed-gear mountain biking?
Danimal-office Dogfish Head
makers of the second strongest beer on the planet!
lol who's the first strongest?
andypugh, what do you think of this logo for my mountain bike parts company? (homebrewed Components) http://img.photobucket.com/albums/v20/danielwilcox/hbcrev2.jpg
I think you might be wrong.
really? wouldnt have thought that
the two sams went back and forth for a while but finally Adams made a brew that costs $150 a bottle and is slightly stronger than Dogs strongest
sam smith maybe?
[18:22:48] <pfred1> http://www.realbeer.com/library/beerbreak/archives/beerbreak20020214.php
Roger and Out is 16.9%, brewed in Sheffield.
if you want to call it beer
Ah, you do indeed win. That's silly!
well I like the guys up the road better : http://www.dogfish.com/
5 turns and I'm in their parking lot
I like the logo.
stone brewery is right around the corner from me
oh yes Danimal-office's Its nice
If it was mine I would want the H to look more like a pedal, but I have little sense of when enough is enough.
ever have arrogant bastard or stone pale ale?
oh oh oh I got it
do it at an angle and have the H a pedal the B the crank arm and the C the chainwheel!
i only make chainrings though
Danimal-office so then make teh C bigger I donno
do it right and it'd look cool
It's good as it is.
i dont wanna make it too busy
it's already pretty busy lol
How much for a set of all-the-same-size double rings for a 4-man tandem :-)
yes it is
how many teeth?
ah bummer, i only do up to 36
Want to keep the chain tension down.
i mostly just supply the mountain bike crowd, so 36 is usually sufficient
Bottom brackets are going to be a challenge, I think I will be using needle rollers and plain shafts to get enough eccentricity for chain tensioning.
just buy an off the shelf eccentric bottom bracket
(No, that's daft, it's another size of hole saw and £20 of big-bore tube to make the BB's big enough)
[18:31:55] <Danimal-office> http://forwardcomponents.blogspot.com/
Do they fit in a standard shell?
one model does
Ah! I feel proper stupid now.
It never occurred to me to have the eccentric outboard of the BB.
But at $150 they are near to the total budget for the bike, and I would need 3.
make your own!
(Don't get me wrong, I wouldn't want to make them for that price myself)
I think that oversize BB shells with an eccentric standard thread might be more "future proof". Bear in mind that the predecessor tandem was 3 abandoned bike frames welded together, and was kept running by scavenging parts from bicycular corpses chained to racks at the end of the academic year.
you're reliving the past man!
Not entirely, this time it is going to be made properly, with a budget.
[18:41:44] <Danimal-office> http://a.images.blip.tv/PDXK-4SeatTandemBikeLandsharkAndAttackBanana185.jpg
I know it needs more work but something like this: http://img24.imageshack.us/img24/5976/hbc.png
4 is nothing very special, I have seen a 5-tandem built as a pacing bike by one of the major manufacturers in 1922.
pfred1, might be hardto read on a t shirt
That page had one interesting bit of info though, that Shimano Hollowtech spindles are 24mm dia. That makes it actually quite easy.
well i gotta get some work done
frallzor: hey dude
Using the HAL "limit" function, is there an elegant way to get bit-signals for "at max" and "at min"?
I could use 2 "comp" functions, but I am wondering if I am missing something.
L84Supper is now known as Arthur2ShedsJack
And closed-loop spindle speed now works. With the small caveat that if you request a speed lower than the VFD can manage, the spindle ramps up to max speed instead.
I am not sure how to get round that, as the PID and PWM need to be allowed to go negative for spindle reversal. The issue is that -max speed is full-pwm as is +max speed, and the PID keeps ramping down to -max speed in an attempt to slow the spindle.
not much longer now ries, just some issues along the way =P
I _could_ try connecting spindle-direction to the sign of the PWM, but that sounds like it would try to dither the VFD between the two directions for low spindle speeds, and that sounds very bad...
I probably need to read up on "deadband"
max, min, what's the diff
As far as PWM output is concerned, none at all, that's the problem.
i have a question
OK. What is it?
i make a circular pocket
x y zero point at center pocket
if i start job when machine is out zero
i receive error message
differ end -- start
Is it using R-arcs or I,J arcs?
i j arc
Move to the position you want the pocket, then G92 X0 Y0 before the pocket and G92.1 after tha pocket
That temporarily makes the current X.Y location 0,0 and the pocket code should then run.
[21:37:31] <andypugh> http://linuxcnc.org/docs/html/gcode_main.html#sub:G92,-G92.1,-G92.2,
the machine is at zero point
Ah, when you said "out zero" you meant "at zero:?
sorry my english is poor
No problem, just explaining my confusion.
i make zero point
after move in manual
With touch-off I guess?
(the effect is the same regardless of how you do it, it should work)
It might be that deskcnc hasn't exported enough decimal places in the numbers.
Can you put the file at www.pastebin.ca so we can have a look?
this is what I want a CNC chain saw! http://www.krusi.com/KrusimaticCNC.html
micges I saw one on a documentary on TV once
three digits after the decimal point
should be 4 digits
pfred1: I wonder how it would cope with an 8"x10" x 20' oak beam?
andypugh it is specced in metric but it is for making timber frames
Is there any way to make EMC a bit less "picky" about I.J accuracy?
And do you need 4 digits regardless of units?
4 digits in mm, Idon't know how many in inch
micges watch the video!
[21:46:06] <pfred1> http://www.krusi.com/KrusimaticVideos.html
pfred1: But the Swiss like to use softwood frames, preferably pre-wormeaten.
billykid2: That link above says that there is an error if the end points differ by more than 0.002mm
andypugh whoever designed this machine spent too much time smoking in Amsterdam too
andypugh: oh I was wrong 4 digits in inch 3 in mm mode
gcode there are in fact in the figures but are zero
pfred1: very cool machine
micges its insane
micges did you see that shaper at the end?
the cutter must have been 6 inches in diameter
well that explains my spindle troubles
JT-Hardinge what is that?
billykid2: Are you getting anywhere?
my spindle revs were off and after careful examination (read the label on the encoder) it is 1024 not 1000 like the rest of them
That machine would have really accellerated our work on http://www.bodgesoc.org/slaithwaite.html
JT-Hardinge so your machine thought it was going in reverse for the other 24?
no lol it just ran slower than asked for
JT-Hardinge I did a terriblly boneheaded thing with my circuit
must begin to work physically on the zero point
Mine runs much faster than asked for if you ask for a slow speed, the PID winds down to full negative, but the PWM can't tell the difference...
billykid2: Ah, is it all defined in relative movements?
pfred1: just the one... you got a ways to go to catch up to me then :)
That seems odd then
OK I'm chucking out my circular saw http://www.krusi.com/LignamaticVideos.html
So, are you saying it actually works of you start at the 0,0 point?
billykid2: paste your program at www.pastebin.ca
if machine is out of 0,0 point i get error
pfred1s videos have reminded me of a loon doing great work with an old Interact2 and hand-coded cutter paths. http://www.craftsmanshipmuseum.com/Tomlinson.htm
andypugh I'm starting to think the T in T-1000 stands for tree
for example if I have a flange
zero point x y at center
make four hole
job finished at x12 y 12
start the pocket file at same center
give a error
billykid2: It seems like deskcnc is making an assumption about something that isn't true.
andypugh: that assumption will be in gcode file
[22:11:45] <billykid2> http://pastebin.ca/1840317
But if you want the pocket at 0,0 is there really a problem?
Looking at the file, it assumes Y=0 at the start, but the G-code doesn't contain a command to go there.
(and all those N0 words are just plain silly)
Edit line 7 to read X -19.4500 Y 0.000 and it will all work fine, I reckon.
once did not give error but the piece did wrong
In what way was it wrong?
out of position
It will have been where the G-code told it to be. EMC2 does actually work. If the results are not what you expected then the issue is far more likely to be with deskcnc than EMC2.
from what I understand missing the line that calls to zero the machine
How does the pocket position align with the preview in the Axis screen? That shows the 0,0 origin and the extents of the cutter path.
it is all ok
So the axis preview and the machined part didn't match?
* frallzor is still PO =)
frallzor what? about your tap?
halted todays work completely and dunno where to find better quality ones fast
I stopped immediately when I saw him do a wrong hole
however my cnc is better than my English :-)
I understand the problem
I have loaded the file into my sim config, and it looks OK
I am guessing you were looking at machine absolute position?
addingy0 to line 7 fixed problem here
I was stupid I did not see that misses the point of zero at the beginning file
Good luck with the rest of your EMC use
really excellent emc
i have pendant
two encoder for spindle override and feedrate
I use a really cheap game controller as a pendant, it actually works quite well.
i have a pendant standard
Do you have it working?
is a homebuilt machine
x 500 mm y 400 z 150mm
You should be able to get the pendant working, but you will need to start editing the HAL file.
You will need an encoder function for each encoder, and a "knob2float" function to convert the output to something that can be connected to the correct virtual pins in the HAL file.
is already functioning well
The machine or the pendant?
You confused me by answering "no" to the same question 4 minutes ago
done long ago I honestly do not remember knob2float
you might not have usd it, there are other ways. I just find the function name amusing in a childish sort of way.
sorry if I understood the cnc was for work
No problem, english is a very stupid language which I would hate to have to learn.
few days have put my hal file
andypugh don't worry in a few years we'll all be speaking chinese
it's all shiny
