hmm, a #7 drill doesn't drill very deep at rapid
in case anyone was wondering...
what happened to the first siz drills?
[00:22:38] <L84Supper> http://www.drillspot.com/products/489721/dayton_2lkr2_gear_head_mill_drill_machine
somebody has these new for $1300
i think I broke my lathe :/
how do I make new lathe parts without a lathe or a mill...
seems like it's not a good night for machining
I could not find a decent mill for the life of me, today I found 3
L84Supper, not until late sept
I'm a bit leery of a new still in the bag mill for less than half price
I am annoyed by the design too
there is a acme threaded nut that is always engaged on the lead screw, and has a worm gear helix on the outside of it
when you engage the feed, the worm gear meshes with a geartrain that drives the pinion for the rac k
because the engagement has not positive locking feel to it(or maybe I am just stupid) , it was partially engaged when I started a cut
and I mangled the top 1/8" or so of threads on the worm gear
yeah, I am not so happy about it
the real problem is I was planning on doing a CNC conversion anyway
which would mean I was scrapping that portion of the saddle
replacing the leadscrew, lower saddle and gearbox with a servo, ballnut and ballscrew
yeah but you need a machine to fix the machine
I could buy the part, I have not found out how expensive it is
probably not very, I doubt more then $50 or so
I have a feeling that people run through them
well, it's probably worth it for your time
so is it even worth my time to do the careful measuring, cut a worm and a gear
and then acme thread the inside of the worm...
* alex_chally is lazy
I found two of these today http://ozarkwoodworker.com/images/AdPhotos4/toolmad.jpg
I'm not sure why people love the Bridgeports so much
alex_chally: if it makes you feel any better my forklift died today
well it's not really broken as long as all you need to do is go up and down :)
anyone know if the bridgport mills have a flywheel above the quill?
I don't think they do
Does anyone know where I can buy parts for Cincinnati Toolmaster? ;-)
ichudov: what do you need?
bridgport parts are sold at most CVS and Walgreens etc
Yeah.. but you have to ask the people at the back counter... they keep all of the parts in the back.. ;-)
so max jitter for servo thread went up from ~9500 to ~17900, base thread is still at the same ~22200 it was when i left ~3 hours ago
anyone got an idea on this: halsampler man page says: "halsampler prints data as fast as possible until the FIFO is empty, then it retries at regular intervals, until it is either killed or has printed COUNT samples as requested by -n." what is "as fast as possible" (like based on what measure in the system does it depend (trying to get some sort of X times/sec idea)) same for "regular intervals" every once per X/thing occuring, how often as a minimum, i
f it can be quantified
sounds like halsampler is actually just writing it out
the X/second would be from whatever is filling the FIFO
I'm just giving you an interpretation of that sentance from a programmers POV, I have NFI what halsampler etc actually is ;->
[02:00:56] <morfic> http://linuxcnc.org/docs/html/man/man9/sampler.9.html
neither explains how often per second/per unit.
I'd guess it'll be at one of the thread rates
have you tried either of them?
i have no machine to sample with, not sure how "real" whatever result i would get by trying it on sim would be
It might well depend on what you connect it to
if you connect it to something at the servo rate, it'll run at that rate
if you connect it to something slower then it'll run slower
i guess the bit i am missing is, how often does anything happen / time unit in HAL
they happen at the rates you define the threads to run at
what is "the servo rate"
user defined in the config file
base period i think its called?
1ms is default
might well be the hal file
threads are defined in the hal file. you name them and define the period.
I think sampler can sample at the defined period and halsampler runs in the user space and emties the FIFO as fast as possible
thats my reading of it
how do you tell sampler which thread to run in?
actually i seem to recall you do that in the halfile when you are loading it
loadrt sampler ......
yeah, but which thread does that get put into, or is that defined by some higher line in the had
so if my servo thread is 1ms, every 1ms sampler can get stuff from that thread, if it's faster more often, if it's slower, less often, but in short "as often as the machine updates a thread, the state can be sampled"
that'd be it
I run my servo thread at 8khz not 1khz though ;->
that's plenty good then
and i think i can push it to 12
addf sampler.N mythread
no need to smaple more often than the machine updates stuff
thats the line
i think this is a perfect answer for my boss too :)
well isn't that nifty. my T slots are spaced right to mount a kurt 6" sideways
my latencies don't seem to go anywhere right now, glxgears died by switching to console and back, it's as if screensaver/dpms did it on the result i saw when i came home, sweet, machine wouldn't run screensaver/dpms
I find that *starting* GL stuff causes latency spikes
cradek: that's always great, our 12" 3 jaw chuck i can mount through to the table, on one machine, not the other
File "/usr/bin/pncconf", line 43, in <module>
ImportError: No module named gnome.ui
while i try to avoid gnome, i never am able to avoid gnome libs
now to reboot and break this working setup, so i can note which bios option (if any did it)
heh... for some of us, attempting to mount a 12" 3jaw chuck on a mill would mean they would no longer have a mill ;)
why avoid gnome?
ds2: it'll have a subplate soon, 3/4" steel, i saw it's already back from water jet, now just needs grinding and drill/tap
morfic: the 3J 12" chucks I have seen are bigger then some of our machines. let alone the weight!
Valen: personal preference? there is too much user convenience causing lags on a desktop
max jitter, servo 11ms and base 14ms since i restarted stats, makes me feel better about newer hardware in case there is no atom board with "enough pci slots" :)
cradek: got any snap jaws for your kurt vise?
cradek: FYI: now where it works: [ 876.968634] RTAI[sched]: hard timer type/freq = APIC/12555048(Hz); default timing: periodic; linear timed lists.
maybe it'll help debug the next random guy's problems, the /0(Hz) part of it
morfic 11ms max jitter is lots and lots?
also try running glxgears but reset the latency test after you have started it
(and ensure you have screen saver turned off)
hm, he left, 11ms is lots and lots? not with a mesa card i think
cradek: although all i read was "turn C1E off, it can cause an extra spike for max jitter" it's what causes my 0Hz issue
ds2: now where i reread my buffer, i do recall i meant to point out that most 12" chucks are 12" :P
Is it ms (bad) or uSec (good)
ouch, 1000 off
uSec yes, 11000 ns
i was too excited i found my "0Hz killing rtai" issue to watch that "little detail"
right now where i turned cool'n'quiet and all but C1E back on, i am at 17.7usec servo and 15.2usec base
this is with a IGP, a gfx in chipset (but does have sideport memory, so it's at least not sharing system ram), might put in my old old radeon to see what it does with a pci-e card
starting a second glx gears and shaking it like a mad man did nothing to the latency max, it's all file I/O (oh what surprise)
pcw_home: and say 25us for a 5i2X is nothing, right? (iirc, the number someone (you? SWPadnos?) gave me was in the hundreds)
stress: info:  dispatching hogs: 4 cpu, 4 io, 4 vm, 4 hdd <--- does nothing to jitter yet \o/ impressive, it's one ting to hear "emc2 uses realtime kernel" and feel comfy about it, seeing it in action is better
ok, my noise is going to die off now, thanks guys :)
100 usec is probably don-care for a 1 mS servo loop rate
thanks, good to know i remembered right
It would matter less if the velocity estimate from the encoder counter was used for the PID loops D term
instead of d/dt position
i gave stress enough workers and MB per worker to take down system with monster swapping, but RT threads didn't care, i guess i might not have to worry about endmills burried into parts too much
I think linux can pretty much come to a halt and the real time system keep ticking (until it needs some OS services)
d/dt? ddt is something i saw mentioned somewhere to create something synthetically if it's not really available (major paraphrasing from what i think to remember), or is this d/dt not at related to the ddt i think to remember
delta position/delta time is used in the PID loop for velocity estimation (at least I still think its done that way)
Both EMCs software encoder and HM2s encoder hardware have better velocity estimation than DDT
(but are not used yet for PID AFAIK)
the ddt i was thinking of was the hal component
its embedded in the PID component as well
pcw_home: what applications would you think would benefit from the better velocity estimation in particular?
A little cleaner and quieter servo in torque mode (where you are depending on EMCs PID loop D term for damping)
Its less important in velocity mode servos where most of the damping is handled (and tuned) in the drive
pcw_home: all i look at is velocity mode, i guess simplicity sake, but i keep hearing Torque mode when i talk about our spindle drive (use as spindle and "C Axis" for positioning for probing)
my goal right now is, get it all working in velocity mode, and since all drives support both velocity/torque modes, i can look into what gives us what when we have a basic working/known good config
Torque mode is nice for a number of reasons:
1. EMC controlled torque limiting
2. Actual torque is just PID output (not need for special measuring)
3. Almost all tuning is done by EMC
But since most drives will do either, you have your choice
(maybe a better way to say #2 to say that load monitoring is built-in)
pcw_home: then i understood the Siemens guy right, when i asked about load metering and torque, that's when he suggested it
torque limiting might be majorly useful too
i will keep that in mind, maybe i'd be wrong to treat torque mode like the red headed step child, just because it's easier to find references to velocity mode easier (for me at least)
and ignore the double "easier" in there :/
i should go to bed, the sooner i go to bed, the sooner i know what "Just got a call from them, Once they crunched the numbers, the one option they had was out due to the 7500 Nm torque? He now has a call in to power tech and is going that route." really means
we don't diddle with 7500Nm, and no other metric is 7500 with another unit, i tell you, i should work 6 days, all day shift, this working 2 nights and being off 4 allows too much oddness to happen until i am back in on days :/
pcw_home: with torque mode it maintains a certain torque, instead of a certain velocity in most basic terms?
what i am wondering about is, maintaining a certain speed, no matter what the material condition seems easy, how does this loop react to varying depths of cuts, to constantly changing load, is that something to even worry about until i understand torque mode?
pcw_home: thanks, i'll try that again a little better formed some time this week, i'll have to read up on that, maybe that voids any questions
That "Milltronics mill" is the biggest fscking joke in IL. It cost $38k in 2000, and the "daughter" wants $25,000 for it. It is a second owner machine and is sold "as is".

If you have an account with newegg - I think you should have gotten a email with the http://www.newegg.com/Product/Product.aspx?Item=N82E16813121399&nm_mc=EMC-IGNEFL082410&cm_mmc=EMC-IGNEFL082410-_-EMC-082410-Index-_-MotherboardCPUVGACombo-_-13121399-L010C
dual core $69
they are the new ones i think
totally passive heatsink
yeah they say that
is the onboard Intel preferred to an onboard nVidia?
wow - read the first few reviews and a lot are arriving doa
unusual from intel
the push from China is to great any more... people are moving back to the country side.
though they are probably selling like hotcakes and your just seeing the dead over represinted
besides, it is a $70 mobo&cpu. get what you pay for.
could be. I have atleast 6 of the previouse atom board - no issues
one is running a little raid box with 8TB esata.
actually the intel mbo's are renowned for their reliability
at least in the server field
still has a parport pin set. same with the msi Item#: N82E16813130281
the MSI comes with a tiny fan, though...
I think this little setup would be a great start to an at home Linux Theatre Box http://www.newegg.com/Product/Product.aspx?Item=N82E16813131663
DDR3, 8-channel audio, HDMI, nVidia ION, wifi and Gigabit.
oohh, newegg screwed up, no wifi on this board. :/

I have one of the MSI Wind D510 boards. it seems pretty nice
Intel lowers the price on Atom to keep Arm from creeping up into the mini-ITX marketplace yet Atom netbooks are running in the ~$400 range
Where Atom fails in competition with Arm is integration. Intels never been very good at SOCs (the Atom SOC is dismal)
I'm waiting to see if Intel will use its muscle to get Atom into smartphones even though it will perform poorly against Snapdragon and Armada
wonder if our line drivers will be here today....
the Arm chip is under utilized in the world today. Too bad they never made it big in the PC market... I am not a chip architect engineer but blogs, forums and such over the years have touted the superior computing power of the Arm over the x86 family. More efficient counts/Watts and stuff like that.
Not really under utilized, pretty much all cell phones use ARM
ARM is in most smartphones and tablets today. Intel dropped ARM and sold it to Marvell 5-7 years ago
about the time they came out with XScale, I think
they sold the PXA / Xscale + StrongArm to Marvell
Marvell just released 2GHz parts at ~1w
And marvel knew what to do with it...
4 core 1-2GHz parts soon
mostly smartphones and network gear until now
TI and Freescale went with PowerVR for GPU's
Marvell has Vivante GPU cores, we're trying to get them to open the specs on and drivers Vivante
PowerVR is closed only
There has never been a x86 family chip that can compete on computing power/watt with ARM
Whether Intel can change this or not remains to be seen (could be the next Itanic)
I asked a marvell engineer to look at EMC2 on Kirkwood and Discovery, they have PCIe
They have an embeddded armada chip with at least a lane of PCIE also
a nice 10" ARM tablet with PCIe for $100 would make for nice UI on a machine
Cabled PCIE is nice for fast real time I/O with no bloated software protocol stack like USB
510 and 300/310
I think the 78100/200 have 8 lanes or so (but only 1 GHZ?)
I'm just trying to plan ahead for commodity ARM tablets and netbooks to be used for EMC2
the targeted at mobile the devices the fewer the PCIe lanes, since they are considered power hogs
the more targeted at mobile...
I dont think the Armada chips have floating point (the 78xx chips do)
some Armadas do have FPU's, not sure of all the part numbers, they keep adding :)
500 and 600 series do, not sure of the 100's
then again who needs and FPU for a photo frame?
heh... they have a GPU for that
oh. well in that case
it's the duct man
ARM uses uboot for firmware and has linux support for over a decade, now they are keeping the GPU's closed
the OLPC project is using Armada 610 so at least the drivers will be open, not sure about the specs
JT-Work: Not yet, still looking
how did EMC2 work out on the TI OMAP for the Beagleboard?
Wish I know more about it though.... like pushing vs pulling, etc.
Or like when you go from 4" to 8" duct
the Armada 510 looks pretty decent 1.2 GHz. CPU, floating point, GBE, and 2 PCIE lanes
hi all nice day in Germany
someone has checkt the grid generator ?
L84Supper: you plan on cross compiling or building natively?
40GB SSD $99
Intel 40GB SSD $99
Intel is coming out with a 600+ gig SSD this fall I heard...
This isn't bad feature wise.... http://newspaperads.mercurynews.com/ROP/ads.aspx?advid=32664&adid=9753073&subid=30857452&type=
So time to toss out our stick drives and just slide a SSD in our pocket.. :-)
ether/wifi, two-sided printing, cd/dvd printing
That is nice.. I hate paying for inkjet cartridges though... plus they dry up.. But that does look nice
$30 get you two sets of NON-OEM cartirdges
My CNC PC boots under 3 seconds from an SSD
ichudov: Why so slow?
our Mazaks take FOREVER
I would guess 1min for the fastest one, 3 for the one with only 64Mb RAM and a 288MHz? CPU
but they all run windows!
the K&T computer boots very fast.

Oh, you're new toy? I thought you already had it?
JT-Work: that is .0001" per div indicator..
skunkworks: Why does it lag half segment at the end of each move?
not tuned. still very good.
Cool, as long as you're aware of it and know the solution =)
overhoots .00005 ;)
goo gawd man, that's like a mile!
hardly worth machining anything with it! ;)
Jymmm: no, I'm making arraignments to have it shipped
you could carve the grand canyon in that
JT-Work: what kind?
something with pallets.... ;)
BIG ASS pallets
[16:27:24] <JT-Work> http://www.gnipsel.com/Bridgeport/bridgeport-pics.htm
JT-Work: what does it have for a control now?
JT-Work: Are they going to pallet or crate it?
The bottom front-end does look THAT strong
Maybr if they bolted some 4x4's to it
it has .... crap I forget
Jymmm: strap it down and tarp it I suspect
JT-Work: how much travel does it have?
I wish I had my sheet here but X about 20 Y about 16 and Z 16"
60 to 6000 rpm bt30 holders 8 station tool changer

not here either
skunkworks: How do YOU know they don't work in IE ????????
this one works http://www.gnipsel.com/Bridgeport/eBayISAPI.dll.htm
that is funny - looks like a normal crt cut into the case. :0
is it posible to re-use the servo drives?
BRIDGEPORT dx 32 CONTROL
is that already retrofitted once?
no, it is orignal
why is that?
the pc monitor and keyboard
that's the way my Anilam is too
feed rate .5 - 295
JT-Work: do you think you can reuse the drives?
it's plug and play just add power
all things work
oh - well - that sucks ;)
I thought it was a retrofit canidate.
the drives are analog siemen drives so I assume when the time came yes
I got tired of looking and this one came along for a good price and close to me to boot
$500 to get it delivered
"It works perfectly as is, lets retrofit it!" -- skunkworks
if the control sucks then I'll rip it out lol
I guess I probably wouldn't buy a working machine.. L)
JT-Work: Tha'ts not bad at all, unless it's 2miles away
350 miles away
JT-Work: great price imo
400lbs palleted from CA to NY was quoted $400
cradek: pc monitor looks like "$500? screw that, let's cut the case and buy one for $50" fix
the crt looks like it was "shoved in" the hole =)
JT-Work: Looks like you could toss in a LCD and still have enough roof for PC etc
looks like it to me too
that reminds me - we need to get a E-stop button at the computer console.

elmo40, know any good Ethiopian restaurants in Toronto?
(or Asian or Italian, for that matter)
there are a plethora of italian places here
we have Little Italy
we went to one last time - by the lake, can't remember the name
so many asian restaurants. we have 4 china-towns
and I think 2 vietnamese-towns
yeah, too many choices, which is why I asked for a recommendation :)
there is a nice place on Yonge St. You cook your own meat ;)
German and french also !
Korean Grill House. Near the Brass Rail ;)
I wonder if there's enough vegetarian stuff there

huh. I probably walked past that place last time I was in town
yeah, one of our guys is vegetarian
i'm cutting 4 pockets in alum and having trouble getting the same measurement for each pocket, is this my latency(42000) ?

climb or conventional cut? are the chips being cleared?
so many variables

piasdom: THEREFORE the new grid python is perfect to check all the backlash and moving
piasdom, does the tool return to the correct spot once machining is done?

whats up guys
calibrating piasdom Mashine
That isn't a real indicator. It doesn't say inches.
im German so it fits
mm's are too small.
piasdom: §axis mill or ?
IchGuckLive: what ? something weird before your word axis
IchGuckLive: yes, 3 .. table top mill from sherline.com
oh i got a different kbord then you folks
so messure the Right move amount first if this is correct your steps/thread are correct
IchGuckLive: you mean the backlash ?
then bet the lowest value to the Manuell move and press back and forth so it is showiung you the backlash
first you got to be shoure that the step and the tread is corecct
IchGuckLive: ok i'll have to wait til this run is over
IchGuckLive: step and thread have worked great til now .... had machine about 2 years now
you got to check this for eatch axis
IchGuckLive: will do
so i guess the Nut is not fixt
i do calibration every 6month on the HAAS VF2
IchGuckLive: i adjust it about once a month
then YOU shoudt no the problem
IchGuckLive: thanks again
FOLKS its late here please can you if it is please check the grid python on siomple g-code if there are misspathes

his toys are bigger than mine :(
[20:13:29] <alex_joni> http://www.youtube.com/watch?v=RV8Dq6mslnE&feature=fvw
now that's a stupid path
hehe, I have met him alex_joni
stuart has some gantry machines that are just huge.
5-axis code with a filleted endmill isn't so trivial to do... (well I haven't tried yet)
skunkworks: any pics of all his machines online?
here's something http://jmkasunich.com/cgi-bin/blosxom/shoptask/wichita-trip-02-20-08.html
those kurt vises alone cost more than most peoples machines...
awallin, if you can apply your mind to put the endmill where the rack form should be and rotate with a linear move its not too bad, I have done a gcode to generate a normal involute spur
archivist: I didn't say he was.. just that the path was stupid
and it's CAM generated .. so I blame the CAM
skunkworks: but is it EMC'ed?
not yet ;)
alex_joni, I have tried to get him to move to emc
to the UK people here, thank you for having strange strange humor
you know, in general
but any of stuarts machines that breaks down will eventually be emc'ed :P
archivist: for a general purpose CAM-function you would need to figure out the local slope of the surface, while avoiding local+global collisions
i submit as evidence
[20:23:13] <alex_chally> http://www.rathergood.com/bagger288
awallin, maybe not, as it can be generated rather than work from surface normals, so you know in advance that as long as the endmill is narrower then the smallest space it will work
archivist: sure if you mean a special purpose cam-script for gears or impellers, that is another thing than working from an STL-file where you have to expect any shape
Dave911: very happy with the performance of those old servos..
Skunkworks: That is great... did you use some older AMC drives to control those motors ???
Does Stuart have any 5 axis gantry mills?
that is what the viper is - 5 axis
Dave911: They are supposidly current product - B40A40AC. They will do brushless - but we are using them for the brushed servos
Oh... ok.. and you got those off Ebay? Nice.
they are 40Amp peak 400v max. ;)
Can you run 2 machines (own instances of emc2) on one PC?
MattyMatt: I don't think so... that question has been asked before..
skunkworks: Nice :-)
MattyMatt: nope, you can't
you can run 2 GUIs for the 2 machines on the same PC though
that wouldn't help much, except with embedded controllers
I'll just have to configure a machine with 2 of everything :)
and interweave the gcode
there's a project for GSoC next year, a version of emc2 with 2 or more independent gcode streams through the same stepper core
MattyMatt: If you put two PCs on the same machine, you could link both PCs with ModbusTCP also via Classic Ladder.. I've been wanting to try that. All of the pieces are there.
they should not be independent on the same machine if they can hit each other
they're not on the same machine :)
if they did interact (moving work from one to another etc) I guess it would need conditional gcode
I don't see the issue with using 2 PCs..
only the cost
did you see skunkworks's link?
69$ for an atom..
this is for reprap scale machines
or you can just pick up some scrap machine
a 800+ PIII will do
surely that's less than 20$
yeah my A1.3 was scrap
ok, final batch of electronics is on its way
* alex_chally is excited
nice Atom, but NewEgg still don't ship to UK afaics
and I'd still need a PCI parport card :)
MattyMatt: it has a parport header.
i just picked up one of thoes d510s
bought a $3 paraport header
ah it has one header? cool
have not tried it out for realz, but I ran the latency tester and it never peaked 17000
even while watching youtube vidoes and shit
alex_chally: sounds about right - that is about what my older 330 atom did. (sounds like if you do smp and isolcpu - you get better.

I am confused by "touch off". I thought I understood it, then it all went wrong.
If I have a tool mounted which has a tool offset, and touch off a new diameter into the G54 system, I expected the current "X" value to become what I just typed in, ie G54 is offset by whatever amount it needs, taking into account the tool offset. So, if i find that the last rehome is leaving things a bit big, touching off into G4 will bring all the tools in a bit?
What actually happened was that I touched off to 16.4 and the displayed X became something like 43. Which I can't explain.
(Cost me an insert, too)
