dmessier: coleman fuel or unleaded gasoline
Guest319 is now known as skunkworks_
same thing.. not dual fuel... ive run GALLOOONS of unleaded thru std lanturns and stoves... cat heaters..
unless you put the Naphta into a gasoline car/truck.... goes like stink..
[01:03:03] <skunkworks_> http://youtube.com/watch?v=Hdhn_j6PrCw
but only for a while.... burns DRY....
you would think I would figure out how to fix the begining hickup.. but I have not tried
its ok skunk..
when GOD made time he made lots of it...
and dont believe time is $$$.... cause we can all make $$ but NO_ONE can make time.. stop feeding the insanity
senseless waste really offends me
we've had two solid days of rain here
the slow steady deep soaking rain
what do I see this evening? some dumbass has their underground sprinkler system running
in the rain
jmkasunich_ is now known as jmkasunich
pooo on them... i need 1 day pounding rain to ge things wet
our rain is rolling thru the few creeks.. (my backyard)..flooding.. aand flushingins
theres a burp..
skunk.. thats sweet... ; )
thats a cute little sewing machine cnc mill
seems well built.. ;
gotta feed me self..
Hi, someone can tell me how connect the nas device across iscsi protocol
you're probably looking for the backup/storage software EMC2, not the machine control software EMC2
this is the machinecontrol software channel :)
thanks a lot, sorry, i am some missing
SWPadnos: congrats on being elected!
you too :)
this makes it all the more important that I actually get a cnc machine and run it with emc
and I need to get off my duff and get my machine working
damn. I thought someone might suggest that
heh - congrats everyone.
It looks like it is going to be another great year for emc2
I sure hope so :)
year - or two ;)
kudos t all
it is 25 in/sec/sec and 200ipm.. although the penguin seems to peak at about 100ipm

he has a few things on ebay
one or two
damn. I've said it before and I'll say it again - flat shielded twisted pair cable is expensive
flat unshielded twisted pair is free if you know who to ask ;-)
heh - got some, thatks ;)
amd duct tape
I may use that first, and get some copper foil tape
that stuff is great (hvac foil tape) - I like it better than duct tape
ouch. $45.40 for a 1" x 18 yard roll of copper tape
I think that's an excellent idea, actually. see you all tomorrow
hmm, I might just make it three
tho the cat in my lap has other ideas
congrats to those elected to the new board
i need a screen in my living room that tells me everything i need to know for the day
or maybe a daily printout
like, what day it is
what classes i have to go to, if there is work
i bet that would be an easy thing to do with a database, webapp, and a cron script
also, a printer
i should get one of those.
Hi, I'm having problems upgrading my ini file to 2.1.7. Can anyone help?
too early for the night people, too late for the day.
seems there's a lot of controversy over scripting.. didnt expect that
different people, different expectations
some don't have any real connection to scripting
* alex_joni giggles
Couldn't contact deer:8010
The web interface is down for maintenance.
too many people think their way is "the" way, rather than "a" way ...
i say the more interfaces the better?
fanuc g-code, rs274ngc, python, APT
well, not necessarily that, but at least "the more possibilities, the better"
none of those has anything to do with the script question :)
um, what was the question?
oh wait - python may have to do with it
"how do i make a bolt circle wizard"?
that is related to the script question
but for that, I'd look at holecircle.py ;)
ugh words - me want pointy clicky
pointy at ity with the clicky thingy when trying to loady a filey
i just want to be able to program the machine without having to know g-code
[12:11:37] <alex_joni> http://www.se-ltd.com/~lerman/gallery/G-Wiz
that is related to the script question
but if i have to write the scripts, i have to know g-code :P
that is related to the script question
ok - time to make the coffee
maybe i should just forget about it and concentrate on cad/cam
btw inkscape has some nice stuff in it
lets see it hogging some plexiglass
well - not the penguin
some sort of image to gcode
it also might be that i've run that program way too many times
fenn: did you see this one? I think you did (actual cutting) http://www.youtube.com/watch?v=dKz81fY1OjY
skunkworks: too bad there were only 5 spots to fill
would have liked to have you on the board too
alex_joni: all 5 where the best choices. :)
you can still be resident loud-mouth and televangelist :)
oh, he sure can do that
oh - I plan to be.
skunkworks: I would have been happy with any combination from the 7 proposed
skunkworks: milling a circuit board would be a good selling point
fenn: I am thinking about it.. but I don't know what I have for tooling that would work for that. I think all the engraver bits are hss. And it is non standard.
hmm - I could mount a dremel maybe pretty easy
what bits does it have already?

0.015" isnt small enough eh
It would be - I guess. I just don't know how long it would last
would it last thru 1 board?
I have had bad luck with hhs and fiberglass
you dont have a lathe do you?
well, nevermind that's kinda overkill
i was thinking you could drill a hole in the end of a rod and glue in a dremel bit
time to fire up the gingery mill
11/64 shaft sounds about right
I could probably make up a wood bracket to mount a dremel pretty quicl
that wouldnt be as cool though
nor representative of the machine
you're selling a lifestyle, man
I probably have some 11/64 drill rod. I could drill a hole as you say and mount a circuit board milling bit in it.
I suppose .023" isn't enough room for a setscrew. ;)
a brass ring around it at the bottom for a setscrew would work I bet
why not splurge and make a spring collet :)
i'd be worried that a setscrew would push it off center
When I had plans to keep it - I was going to make a different spindle for it. That would have been something will a collet.
the spindle comes out with 2 setscrews I think.
with a collet
* jepler grumbles -- still no shipping notification for his new cnc router
on a happier note, I got my openmoko :)
have you gotten it to do anything yet?
but no shipping notification from Mesa
it almost boots
and has a very high resolution screen - the boot console messages are about 3-point
is this for a particular project, or just because it sounds cool?
kind of both
I like supporting open source projects when I can, plus I have a customer who wants some remote monitoring apps that could benefit from cell technology
well its cheaper than an airplane
even a model airplane would get more expensive
after crashing it twenty times maybe
well, once you throw in a high performance motor and driver (and battery), nice remote control unit, several servos ...
a paper airplane would be much less expensive
skunkworks: nice video of cutting chips in the air
the machine seems really snappy
I've made tool holders for small tools out of brass. In the lathe turn the outside and drill the end in the same mounting, put a bit of shellac in the hole, warm it with a flame, put the tool in, and let it harden while keeping it centered (touch the tool with a peg against the tool rest while the work is rotating)
it doesn't matter if the hole is too big (made with a full size 1/8 drill bit)
it's a watchmaker trick to center parts for turning: put a piece of brass in a collet, catch the center and make a dent the right size, fill with shellac, center the part while it hardens
for engraving PCBs it would be plenty strong
I did it for using regular drill bits in my 1/8 collet: just make one for each drill bit (drill with the bit itself, then reverse it and shellac it in)
yes - that should work great
hm, I think I was running my crappy little motor at twice the rated current with the xylotex. I didn't see the note: "When Setting Vref for a UNIPOLAR rated motor, use a current of 50.0% of the rated unipolar current, when wired for series mode."
I think I may have to do a milling of a circuit board..
no wonder it got so hot after an hour with the amp on
the faceplate says "3.6 ohm 5V 1.36A
" and the resistance from center tap to end of winding measured about 3.6 ohm ..
Using higher current can "smear microstepping smoothness and accuracy", according to the pd
[14:53:02] <cradek> http://www.tp178.com/jd/watch-school/3/staff-on-lathe.jpg
heh - I have heard a bit of different 50% or .707 of rated current
yikes - I would shake and break it right of..
if you so much as sneeze, that'll snap
notice the collet is 2-something (2.x mm)
I would use epoxy 5 min (it is what I have)
I wonder if you can get chip shellac at a hardware store
with shellac if it takes you a few tries to get it centered, no problem
epoxy is kind of a commitment
just dont overheat the shellac
yeah it should be just soft
these are all 1/8 shank - I would think I could ream it to a slip fit
for this purpose
I bet archivist has done this a few times too :-)
cradek actually only doing rollers etc
you don't reverse a balance staff this way to turn the other side?
no turn it in one
you're better at it than me then
(no big surprise there)
hot glue gun
I have used broken carbide pcb drills to make gravers for turning small stuff
how do you sharpen stuff that small?
hard work, and try again
often wrong first time round
thats what google sayz
when turning up a small pinion I can often go through a number of resharpens
when hand turning with a graver though you just rotate/move the tool for a better edge
so its not shaped like a lathe bit?
[15:11:09] <cradek> http://www.engravingarts.com/jpgs/squareGraver.jpg
does anyone use EDM in watch making?
fenn: yes lots
fenn: a traditional graver is square cross section with the business end ground and sharpened at an angle to make a diamond
i was thinking about making a qctp holder for that type of bit
hmm the machine shop here doens't have 11/64 drill rod
fenn: I make a few engraver bits for pcb milling before I bought the thinktink bits.
I would put the broken carbide in one dremel and a diamond wheel in the other. I would turn both on to make the carbide into a point - then dremel off that had the carbid in it and grind half of the carbide away to the point. Then releave it around the outside edge.
it worked ok - but the bits from thinktinker work so much nicer\
skunkworks: how bout drilling a hole in the back of one of the bits you've got?
I don't know how hard they are. (if they are hard the whole way.
carbide drill ;)
heh you could make a carbide gun drill from a broken bit pretty easily
I actually probably have 1/8 carbide drills. I would have to look
what does a gun drill look like?
i guess i meant "straight fluted drill"
often with a hole down it for lube

Hi, I'm having problems updating my ini file to 2.1.7: the machines moves extremely slowly and I get the message: STEPGEN Channel 0: The requested velocity of 28000 steps/sec is too high.
could you pastebin.ca your ini?
It is here. It is a modified version of stepper xyza: http://pastebin.ca/665824.
Thanks for the help
I am trying to update it with the values from http://www.sherline.com/emc/mill_mm_freq.txt,
which is for an older version of emc.
My A axis is working fine, I just need to fix the xyz.
ok - looks like they were running a base period of 20000 - can your machine do that?
the maximum steps per second you can run right now with the baseperiod set to 50000 is 10000 which is 12.5 mm/sec
I'm sorry I don't understand your question. The machine is a normal Sherline mill.
what kind of computer is this on?
20000 is doable on most any computer
if not, the machine locks up anyway
I have an AMD64 laptop (Acer Ferrari) running i386 ubuntu
is it a units problem? did you switch from inch to mm somewhere?
MACHINE = EMC-HAL-STEP-XYZA-IN
i dont think that does anything but it implies that you started off with an inch-based config file
ITs a mm machine but the only xyza config I found was inch. Either way, the settings are wrong
it looks like most is correct - try BASE_PERIOD = 20000
i thought there was some kind of warning dialog that calculated this stuff for you
<Noobie1000> Hi, I'm having problems updating my ini file to 2.1.7: the machines moves extremely slowly and I get the message: STEPGEN Channel 0: The requested velocity of 28000 steps/sec is too high.
right. the old behavior was just "following error" i think
I still get the same error with BASE_PERIOD = 20000
Noobie1000: also lower your max velocity to 30
I should say - how fast do you want to go?
* skunkworks isn't a metric person
the velocity change didin't do anything either
Sunkworks thank you, it kind or works, now. I still get the error, but the axis are moving at the proper rate.
[17:29:30] <skunkworks> http://pastebin.ca/665842
axis0 did have a few problems..
MAX_ACCELERATION = 15
STEPGEN_MAXVEL = 10.00
STEPGEN_MAXACCEL = 20.0
MAX_VELOCITY = 8
Your new file works great.
where you using emc1 up to this point?
The Sherline machine is "new" I didn't play with the bundled EMC version much, and so I tried to upgrade right away.
nice - I am sure you will like the axis interface.
Its definitively much better than the old one. I wouldn't go back. Would it be hard to get the ini files for basic Sherline machines in CVS?
Maybe I can post mine on a wiki somewhere
That would be great.. (I am not a developer)
i thought the default stepper configs were for sherlines
Noobie1000: do you have the sherline A axis?
The INPUT_SCALE is wrong
Yes, I have the Sherline CNC rotating table
I think it would be great to get a perfect sherline XYZA configuration in the future releases
I would be happy to help with this.
without having one of those it's hard to guess what the proper accel/velocity are
that's great. when you are happy with it, you can send it to me, or any other developer, or put it on the wiki, etc
OK, will do. However, I think I can only provide a mm version (for XYZ) because my machine is metric.
It should not matter.. I assume they use the same machine be it metric or english.
(I could be wrong)
I know you can get either leadscrews. I don't know if they use different screws for their cncs though.
Noobie1000: with EMC2 you can run inch or mm gcode equally well, just put G20 or G21 at the top of your program
I have a metric lathe but often (usually?) use inch gcode
does it matter what kind of lead screw is on a CNC lathe?
From the docs: The difference between inch and metric models of the lathe and mill are not just the handwheel markings, but include the leadscrews, nuts, inserts, handwheels and tailstock spindle.
only for accuracy. EMC doesn't care
The handwheel on the inch models moves the slide .050" per revolution and has 50 graduations of .001". The metric model moves the slide 1mm (.03937") per revolution and the handwheel is graduated into 100 divisions.
Noobie1000, it seems cleaner to define the machine as inch or mm based on screw pitch, but it really has about zero effect
any opinions of lube for an unknown manufacture ball screw?
the main difference is whether you get an integer number of steps per unit
Noobie1000 could configure his machine in inch, his scales would be strange numbers (not integers), but EMC doesn't care
Noobie1000: did you say your input scale was wrong? (800)
sounds like metric 1/4 stepping
" · 800 steps per revolution (microstepping), equates to 16,000 steps/inch with .050" pitch leadscrew" -- sherline.com
I thought he had a metric machine - one turn per mm
yeah, I am just confirming that it's 800 steps per revolution
I am confused: if I try to create an inch.ini file for my machine, it won't work with the Sherline inch model, since the pulse won't generate the same displacement.
your scale would be different, that's all.
but there's NO reason to have two configurations for your machine.
so for a 1mm screw it's SCALE 800 for a mm inifile and SCALE 20320 for an inch inifile
(if I did my math right)
emc2 foam cutting pics: http://i14alberta.ca/gallery2/main.php?g2_itemId=1014
You are right, cradek. I only need one file, but I would have liked to provide a Sherline config for both metric and inch models.
oh I understand now, sorry
Should I use TASK = minimilltask (instead of milltask) for a Sherline mill?
that's old emc1 advice
Noobie1000: you haven't gotten any realtime latency errors on your portable?
cradek: any manuals for the bridgeport?
the mesa parts will be a while anyway.
steve stallings said he can copy the manuals for me. he's been a huge help already.
he seems like a nice guy.. ;)
meanwhile, the machine is working with only minor quirks now.
did you fix anything or has running it helped? Plugged/unplugged card
switching the X and Z amps caused the occasional amp fault to go away (!?)
I didn't get latency errors yet. But my Y and Z axis seem to be inverted.
Noobie1000: negate the scale
skunkworks: also, it forgets/trashes the saved program and tool table when it's turned off, although I tested the batteries and they are OK.
it's easy to reupload it though.
oh - so you can upload them serialy?
yes you can upload the gcode with a serial port
there are a few contortions but not bad
it has a (very basic) line editor that you can run with a serial terminal. So with care you can use it to "type in" the program.
that will do a lot of work for you.. You just need to figure out what ;)
are you thinking of using the existing servo amps? and how annoying are they?
I have heard they have a pretty low switching frequency
they perform OK but are very loud
yes I'll surely use them
that is what earplugs are for ;)
it's drowned out by the phase converter, air compressor, and (of course) spindle motor
keep an eye on ebay - I am sure you could get the amps pretty cheap
I bet Jon E has some too
not that they would be pretty hard to fix
I found the R key yesterday..
* skunkworks is a point and clicker..
cradek: the email from watchman1 - I have seen that happen in 2.1.7. I have not really looked into it.
I figured it was a g10 offset (must have been in there from the get go)
I have not seen that problem... need more information to reproduce it.
yay foam cutting
It was a fresh isntall updated ubuntu emc2. When selecting the stepper_inch.ini and you go and home each axis - one or more do not 0 - they actually change to some non-zero number. (installed 2.1.7)
(I had actually thought it was me)
wondering if the var file in the installed 2.1.7 stepper_inch.ini has offsets in it.
ah that could be...
I had cleared the g92 offsets but didn't change anything.
ring tones would be nice too. "
I think it's insulting to machinists to think we have to rearrange the buttons to match a control they already know.
for instance, I can be pretty sure that someone who is used to an R2E3 might like an incremental jog other than .0001"
I just don't see "the emc interfaces are bad, commercial interfaces are good"
sorry, am I trolling?
maybe all user interfaces suck, it's just that they all suck differently, and you can get used to any particular kind of suckage.
jepler: Kirk's latest email
lerman: did you just unsubscribe from emc-commit?
I don't think so. I was deleted because my email was down at some point. And I never go around to figuring out how to resubscribe.

I'll put you back on the list

It depends. I don't know what will be committed.
it really won't matter
not like 0Day commits or anything

cradek: hm, that surplus center enclosure might be tall enough, the power supply (tallest thing in the box) is 1.66", the box is 2 1/8 inside
it looks like it's meant for mounting on a wall - not sure how "friendly" it would be to a desk etc
and the power supply is just a little too long to fit in the short dimension, so it would use up 3.9" out of 7.125"
back to thinking it's too small
skunkworks: oh, just keep it already. ya know you want to.
he actually wants to just send it to me
I bet he prefers shipping to europe
cradek: when you say you're looking for a small LCD, do you mean under 15"?

yes, even a 10" or so 800x600 would be great
so like this but not an arm and a leg: http://www.dgahouston.com/monlcd10.htm
ouch ouch ouch
yeah that would be great.
there are a lot of them on ebay that are for cars, but I doubt they take vga and just work
yeah -- I think that composite input (and resolution more like 640x480) is most likely
ooh the $521 version has a touch screen. that would be so cool.
I do have a 9" 800x600 monitor. Maybe I can mount that somehow.

'let the conversion begin..'
how's linux support with touchscreens?
most are simple HID devices
just like a mouse
at least some I've seen
they appear as a mouse to the computer?
don't mice have relative position adressing?
that's why you have a controller in there ;)
I know some older serial touchscreens sometimes had some strange protocol
no, I mean't the way that data is sent over the usb/ps2 interfave
but it would be incredibly stupid to invent some strange USB stuff
I wouldn't be surprised
is there any common reason for insanely long latencies with non-RT inputs? like 1s delays on the keyboard?
I could see with a a really low base_period anything non realtime could be a crapshoot
my base period isn't very low though
lerneaen_hydra: only when emc is running?
typically latency is 20µS, base period is around 40µS
alex_joni; hmm, I don't know actually
I always run emc on that computer :p
well.. I'd try that first ;)
I only notice it when jogging
hmm.. might be low accel settings?
the thing is I've had the same behavior on another EMC machine
nah accel is around 200mm/s²
and the latency is intermittant
sometimes it's not noticable
I'm not sure but it seems that the latency doesn't change while the computer is running
it only changes between boots
and peculiar even
very much so
so much that it's probably an error on my end
wth is a subneck?
I don't know that word
that's odd.. watching some tv show, and they use that word
maybe subneck as in sub-neck, as in below the neck?
I think the original (english) word is Unsub
I don't know that word either...
[21:04:02] <alex_joni> http://en.wikipedia.org/wiki/Unsub
wikipedia does though
the show is actually criminal minds.. so that fits
I didn't know the word until the show 'criminal minds' they always call the unkown serial killer the 'unsub'
heh - I didn't read alex_joni comment
skunkworks: you were correct
23:46 < skunkworks> I will shut up now. sorry. I don't think I am all here
I was just looking at some very interesting combined axis technology
imagine a big gantry in X
and a reasonably light/fast Y axis
Y can manage reasonable accels (1, 1.5G )
X cant, so you have to slow the whole thing down to 0.5G or so
* alex_joni says rotate the part when needed
* robin_sz points to the 3m x 1.5m sheet
heh, that reminds me
so you add an extra sub X axis ..
seen a nice turn/tilt table when I was in germany recently
plus 2m vertical axis to move the whole table up/down
that does small moves .. and starts off bigger moves, the main axis catches up when it can
robin_sz: that's exactly like Till's emc controlled machine
there was a video someone had on here that had something similar - a small fast axis parrallel to the slow larger axis.
he called it a mixer I think
alex_joni: do you know where the video is?
[21:19:35] <alex_joni> http://audiflitzer.de/mixer.html

where's the python path?
whats the data rate that the parport can achieve
Guest783 is now known as skunkworks_
Hello, does anybody have exp. with converting an anilam crusader M to EMC2?
what is it?
jepler: before I try it (or find a picture) do color pictures work ok?
for image to g-code
the machine is a knee mill, it already has servos and scales installed.
skunkworks_: it's not hard to try it :-P
jepler: cool program (first time I have used it)
skunkworks_: if I was thinking properly I would have automatically converted a color image to greyscale
Adam: ah I see. I don't know of anyone doing that particular machine, but there are lots of knee mills running EMC.
is there anything special or unusual about it?
nothing I am unsure of the electronics side thats all
the boards I would need to purchase and configure for example
Adam: does it have encoders or resolvers on the motors?
it has tacho's on the motors
scales on the table
there are quite a few options for what hardware can be used to drive it
oh, no motor encoders at all?
interesting, is it really tight or is there some backlash?
jepler: is the convert to arcs working in trunk
the anilam control is using the scales as feedback
here is a recent new conversion of a knee mill done for daily use in a machine shop
so the table has feedback
do the tachs hook right to the amps, or to the control?
to the amps
ok so the control pid is just a position loop still, that's good for EMC
do you know what the amp takes for input? +/-10v for example?
I dont know that yet
are the amps separate from the actuall controller?
skunkworks_: I think so, not sure
that is good. Your going to have to know what kind of signal your amps take and what type of signal the scales output like quadture.
jepler: I may try it :)
jepler: the last I has seen is you had disabled it.
you will need hardware to count the quadrature from the scales. We have several supported interfaces, depending on whether you want PCI or parport hookup, whether you need any ADC, etc
you surely won't need ADC for a knee mill unless you're going to do something unusual with it
anilam.. should be an easy fit
the mesa and ppmc are plenty capable and affordable
if you might want to do rigid tapping some day, think ahead and make sure you have a spare encoder channel for the spindle
dmessier: do you have experience with anilam?
cradek i was looking at the mesa 5I20 FPGA I/0 would that be suitable?
they have a nice analog servo interface card
+-10 out, differential encoder in
just wire it up
do you have a number for that?
also they have some isolated IO boards for limit/home switches, spindle fwd/rev, etc etc
is it possible to have a second spindle driven by a stepper for rigid tapping?
Adam: analog servo interface is 7I33. Isolated IO is 7I37.
(I'll be using both of those on my bridgeport very soon)
you'll have to decide whether 16 in/8 out is enough - it's not a lot of extra.
ds2: it would take a BIG stepper to tap wouldn't it? why a second spindle?
I have only 2 axis right now, in the future i would like to add the z-axis.
oh it's only XY under cnc control? interesting
Once I have thoose two boards what are we looking at for configuration and wiring? is it a very time consuming process for a rookie?
yeah only xy
I hesitate to guess because I don't know your skills.
