not really considering HIS contact is UNCONTACTABLE.... PEEhead....he is
I must be scary
That is what I have been saying for a while.. ;)
heh - who needs M5 x 6mm setscrews?
(I need three, they come in boxes of 100)
got my timing belts figured out, got setscrews, got a pulley.... I wonder what else I need from McMaster Carr that I will remember 30 seconds after I hit the "submit order" button?
I'm gonna find out
6mm bolt, head cut off, hacksaw a screwdriver slot. buy at auto parts store in single qty. may be cheaper than box of 100.
I have slotted screws of dubius quality already (came with the chinese pulleys)
I want proper socket head ones of good steel
its only $4 and change for the box
if they were an inch size I wouldn't mind at all - stocking up for future projects, etc
but I don't normally use metric stiff
oh, the shoptask pulley screws , yeah, crapola
there are probably a few more places on the machine where I can use some of the new screws
it's funny, when I first got into machining I thought of "steel" as a single generic substance
JymmmEMC: you around?
single phase motors are evil
that is true
at least for now I'm going to have to use the existing motors, but I'd like to be able to start and reverse them using ordinary three pole contactors
(eventually I will replace with three phase motors, add a VFD, and use the contactors to select between mill and lathe motor)
$420 out the door.... both front rotors, pads all around, and an oil change.
That's replace the front rotors, not turn them.
i really enjoy fried rice
also for christmas, someone buy me a warner & swasey #3 turret lathe
toastydeath: try sex some day, you might like it.
i do frequently!
it is pretty good
but i already get that for christmas
toastydeath: no no I dont mean "Sex-for-one" in the single serving packages.
neither did i
also I've noticed the people who insist on others getting laid themselves have problems with intimacy
and if you have to wait till Christmas for it, that's an awefully long time to go
in one form or another
* cradek snickers with toastydeath
so i can only assume you've got some emotional issue you've left unresolved
lol, nah, justmore fun to tease about it.
not really, considering you're not terribly creative and nobody's laughing with you
* cradek tries to figure out how this is related to emc
the only intamacy problem I have atm is with SNMPd
cradek: same as fried rice does
cradek: i've got no clue, i said i wanted a turret lathe
and captian commitment here tells me to get laid
anyway a couple folks have turning work that needs to be done
and a little turret lathe with a tracer would work great
toastydeath: it just seemed that you said this out of the blue ---> toastydeath: i really enjoy fried rice, so I was returning the favor in kind.
no, i said I enjoyed fried rice
which is not particularly offensive to anyone
out of the blue
because I do, indeed, enjoy fried rice
everyone likes fried rice
see? he gets it.
and instead of answering in kind, with "i like biycles"
you insult me, completely unprompted
so that leads me to assume you have some pressing intimacy issue lingering on your mind and decided to take it out on me
my favorite is 'tofu lemon grass' at the local place
cradek: is that a fried rice or an entree
it's an entree
the fried rice is good too though
and the spring rolls (the fresh vegetable in rice paper kind)
i go with the orange chicken and california rolls
i'm not a fan of spring rolls! i don't know why.
that's more for you, i guess
my friend says she thinks they look like under-sea creatures
so she won't eat them
you know, kind of translucent
some sort of jellyfish maybe
I sympathize with that, but I like them
with uh, lettuce innards?
lettuce, sprouts (the fat ones), tofu, mint?, peanuts
looks like I'm going to need another Mesa board
just bought some analog command servo amps for my router
neat. you'll like it better than stepping.
I have one for my mill, but I'm very slowly figuring out how to do estop and limit switches
very, very slowly
usually the amps will have a positive and negative limit input. so, you can wire it so it cannot power past the limit switch no matter what happens. I think this is very nice.
my bridgeport doesn't use this (!)
if you start it on a limit, you have to figure out which way to jog, and get it right in only one try
the mill weighs 5500 lbs, I decided to blow the power if it hits a limit switch
or jam it against the hard stop?
eric_U: how do you get off the limit if the power is killed?
with the router, I can be a lot more free
can you get at the screw with a wrench to turn it?
I can move it by hand
how often am I going to hit the limit?
cool (and surprising)
eric_U: not often at all, _once_ the mill is all set up
you mean at first, or after it's configured?
right now, I can move by hand
but before you get the soft limits set properly, I bet it will happen a few times
if I put all the covers back on, only x
we did it a few times on the mazak
on that machine, X is the only one you can reach/turn by hand
I did it twice I think
I did it too
so nothing broke I take it?
we wired the mazak like you wired your mill - limit switch kills power
and it wasn't going fast when we hit the limits
I'm going to install home switches
not sure what the travels are though, I can see hitting the limits finding that out
home switches plus soft limits will keep you off the hard limits once everything is set up right
if you remember to home
shamefully, that was my error both times
I can see that
yes it's arguably a bug in emc to let you run gcode without homing
we have an accurite that doesn't let you do much without homing
ditto - time to walk the dog and then get some sleep
the walmart gOS computer came with the iD
what's the "iD"?
iDot pc2500G motherboard http://www.idot.com.tw/en/products/mb-pc2500g/#
it came with a modem in one of the 2 pci slots, and 512meg ram. dvd-dc-rw, 80g baracuda
6usb, built in audio and video
paroport, serport, case, wheel mouse, keyboard, usb powered speaker preloaded w linux ... 200$ at walmart
too late to fire it up now, will try it out this eekend
Jymmm: come back....
steve_stallings is now known as steves_logging
JymmmEMC: you at work???
anyone willing to answer some newbie questions?
HMTR: just ask away
I'm confused on the mesa stuff. Is there a limit to the amount of I/O I can use? Can I add additional modules for more?
I'm also more than willing to read even more documentation, but haven't really found what I'm looking for in the last couple of days
Up to 4 mesa 5i20 boards may be used with emc.
maybe you should start by what you need..
each one has 72 I/O points, some of which are used for special functions such as DAC and Encoder
the general documentation on the mesa 5i20 card in emc2 is: http://linuxcnc.org/docs/2.2/html/hal_drivers.html#r1_5
the limitation of 4 cards per system I only know because I knew where to look in the source code for it.
Ah! Thanks for the link.
note that the pinouts in that section are from the board itself
the 7i33 and 7i37 breakout boards have different pinouts
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-11-28.txt
so am I understanding that If I want a 5 axis analog system, I need 2 boards min because there is only 4 dacs?
unless you can write vhdl to add the 5th axis to the first board
I think there is a 8-axis vhdl for the board, but not a driver for that
HMTR: yes. you need one dac and one encoder per axis, and there are only 4 dacs and 4 encoders per board
er, I guess there are 8 encoders if the documentation is right
that's on P2
yah, that's why I was confused
eric_u and alex_joni are right that with a programming effort it might be possible to use more of the I/O points as DACs but that is not something to be undertaken lightly
question is if it's been done already
HMTR: the guy from mesa said on a couple of occasions that a vhdl for 8-axis exists (hostmot-8 or something like that), but there's no emc2 driver for it
[13:32:20] <alex_joni> http://osdir.com/ml/distributions.emc.devel/2006-12/msg00063.html
I think SWPadnos has been meaning to get it working..
can you map the unused encoder channels on the second card to i/o? I'm guessing not...
hmm.. you should ask on the emc-users list for a better response
but I *think* you can access any pin as IO or as the predefined function
(don't take my word on that..)
P3 and P4 can be used as digital I/O if the special encoder function is not used
I don't think P2's pins can be used as digital I/O, regardless of whether the special function is used -- there is no "Function/HAL-pin" column in that table.
the 8 channel vhd files aren't in the source package I downloaded
I'm sure Pete would help fix that if someone was really interested
I thought someone had gotten the 8 axis files merged with emc
[13:40:20] <alex_joni> http://www.mesanet.com/software/parallel/5i20.zip
it's in there
[13:40:55] <alex_joni> http://cvs.linuxcnc.org/cvs/emc2/src/hal/drivers/m5i20/hostmot5_src/
skunkworks128: you were right.. but I'm not sure if the driver supports it
[13:41:34] <alex_joni> http://cvs.linuxcnc.org/cvs/emc2/src/hal/drivers/m5i20/README.txt?rev=1.3;content-type=text%2Fplain
someone had talked about it.. I can't think of who it was.
guess I gotta update my source
eric_U: it's quite an old change
the source I downloaded was emc2-2.1.4
but it wasn't cvs
I checked out a cvs version, but I have no idea where I put it
ok, 2.1.4 is probably older than these changes
2.1.4 only contains improvements from 2.1.0 which was released in 2006 May 08
I suppose I should update my cvs
if I checkout trunk, it should be the 2.2xx+ version, right?
if you want to get bugfixes before the next 2.2.x release, then you want the "v2_2_branch" (cvs co -rv2_2_branch). if you want to get new features then you want the TRUNK (cvs co with no -r flag)
thank you so much for the help. I'm going to do some more research so my next round of questions will sound a little more intelligent!
HMTR: come back anytime
awallin I think was the one that worked on the *
[14:04:11] <skunkworks128> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2006-12-30.txt
I only see 4 axis there
sry I see it later
as stated before, the c code is all 4 axis
naming on those files isn't the best if there really are going to be different versions
jmkasunich is still working on the be all - end all mesa driver - He hopes to work on it this winter
I like a modular approach
plus it will have hardware stepping

Hi every body, I need some help regarding emc classic ladder
classic ladder works with GUI but stops working when i use nogui option please help me out/
cnc_engineer: I cannot help
cnc_engineer: can you be more specific? I just used the sample configuration "demo_sim_cl" which uses the classicladder --nogui flag, and it seems to work
I believe it works because after the GUI appears I can look at the state of the pins through halmeter; I see that classicladder.0.out-00 changes when I press the GUI estop button
what version of emc are you using? what did you write in your .hal file? what behavior did you expect? what behavior did you observe instead? what change to your hal file (e.g. removing --nogui?) makes it work as you expected?
does the demo_sim_cl configuration work for you like I described it (the classicladder gui is not automatically loaded, but halmeter shows that classicladder.0.out-00 changes when the gui estop button is pressed)?
Jepler:I am using Emc ver:2.1.0.When I change the statement "loadusr classicladder demo_sim_cl.clp" to "loadusr classicladder --nogui demo_sim_cl.clp" it stops working and no output changes
hm I can't reproduce this problem you're having
for me, all these variations work: loadusr -w classicladder --nogui, loadusr classicladder --nogui, loadusr classicladder
I thought there was issues with classic ladder in that version..
in all cases I see that classicladder.0.out-00 changes when I press the GUI estop button
yeah quite possibly -- that version is ages old
jepler: yes, mine is 2.1.0.
it appears that this bug was fixed in 2.1.1: http://cvs.linuxcnc.org/cvs/emc2/src/hal/classicladder/classicladder.c?rev=22.214.171.124
you should upgrade to a newer version. You can upgrade to 2.1.7 and retain compatability of all configuration files, or upgrade to 2.2.1 with a few minor configuration file chanes.
or you can rebuild 2.1.0 with the specific fix for this bug: http://cvs.linuxcnc.org/cvs/emc2/src/hal/classicladder/classicladder.c.diff?r1=1.8;r2=126.96.36.199
[15:47:23] <cradek> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/debian/changelog?rev=188.8.131.52;only_with_tag=v2_1_branch
* fix bug that left the spindle on after abort
* fix problem with MACHINE ON which was left active on shutdown
there are other very important fixes too.
well yes, there are a ton of other bugs fixed
Thankyou very much. I download the new version and try it out.
my brain just refused to read "2.1.0" -- why would you be using that version now, when about 8 months and 8 releases have happened since?
because you got a cd a while back and you never install any updates.
I forget that not everyone is like me -- easy always-on network access on the machine that runs emc
I love getting updates. I am dorkey that way.

vernier calipers: I can pick "carbon steel" or "stainless steel". which do I want?
price is within 10% so I don't care about that
I have always used stainless steel ones..
WOuld you worry about the carbon steel ones getting surface rust?
seems like nonrusting and nonmagnetic would be bonuses
do you know why would someone choose the carbon steel?
not off the top of my head - I bet they are harder.
I bet you're right
I know the cheap digital stainless ones we have dent easy
I don't know if the stainless ones are of the non-magnetic type.
i'm happy with the $12 enco ones, which are stainless
fenn: that's probably about what I'm getting (but 12")
if they are 'hardened' I don't know if they can use strictly non magnetic stainless.
so about $25
but I may be talking out of my a$$
skunkworks392: I'll let you (and your ass) know when I get it
fenn: played with the hexapod sim a very little bit.
why do the struts separate?
these calipers are hardened and magnetic
there you go.
[20:54:39] <skunkworks392> http://www.electronicsam.com/images/KandT/DSC_0242.JPG
the struts dont point in the right direction because of ... a bug :)
i think the math may be wrong, or i may be doing rotations wrong somehow
its very simple but i cant figure it out
heh - been there
Not to be funny, but why do you like digital calipers, easier to read?
old eyes? or more precise?
easy to zero
i much prefer dial calipers, after having started with digital calipers
zeroing is nice but I use a dial anyway
I don't like dial.. Too easy to get crap in the rack
I'm always afraid that the battery would wear out at the wrong time when you need it most
you should try both I guess
yeah you'd think a bellows wouldnt be too much to ask
na - most start to flash months before they are totally dead
even the cheapies?
mine never started flashing, they just went bonkers
I guess not all ;)
have an extra set of batteries in your tool box
or a dial caliper :-)
what cradek said
they dont work well at cold temperatures either
have a vernier too in case you get goo in the dial mechanism
and a set of gage blocks for when you have to re-build civilization after nuclear armageddon
I hate verniers - mainly because that is what I started with.
hmm.. I saw some nice calipers once
they were ~6000mm long
we have a 4'er
yeah, same here
er, so, what do you measure with those?
how heavy is it?
fenn: big parts.. but you need help
very short people?
cradek: short people?
* JymmmEMC lol @ cradek
it is graduated so that to figure out the last 25,50,100 thousands - you have to figure out what mark lines up.
thought you were talking about the 6m one :)
you can probably measure 6 short people at once with that
[21:03:43] <JymmmEMC> http://www.vernier.com/
* cradek gives alex_joni a tape measure
we have done jobs that required measure that distance.
* JymmmEMC gives alex_joni a folding yard stick
show me one of those that can measure with .1mm accuracy
[21:05:44] <skunkworks392> http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=52
mm but you get the idea
alex_joni: per your request... http://www.garrettwade.com/jump.jsp?itemType=PRODUCT&itemID=105436
JymmmEMC: that's only 1mm accuracy
alex_joni: what's a decimal point between friends ;)
gee is 1mm good enough for woodworking?
[21:08:20] <JymmmEMC> http://news.yahoo.com/s/ap/odd_million_dollar_bill;_ylt=Aoy9iDc57Pc_hUNwcbNebBXtiBIF
JymmmEMC: I was really impressed when I saw that big one
alex_joni: that's what she said =)
it's about 200mm wide
and 10-15mm thick
dangit I needed two end mills and ended up spending over $100
fenn: if you're not doing inlay or mitered corners I guess
cradek: justifying the overpriced shipping charges?
free shipping (enco)
JymmmEMC: well, my idea of woodworking is 2x4's and drywall screws :P
fenn: and sometimes lag bolts
fenn: no nail guns?
I mean, isn't a nail gun why ppl do framing in the first place?
if not, then it's just target practice or shooting yourself in the foot.
OH! Have you guys seen this yet? http://stanleyfubar.com/
Don't forget to destroy the bunny!
Is everyone still destroying the bunny or what?
a piano can really wreak havoc if the cast iron frame breaks - there's a lot of energy stored in the strings
actually i think they use cast steel
never heard of cast steel before.
forged yes, not cast.
well, now you know
is emc supposed to go to a predefined position when the tool change is commanded?
it does if you define a tool change position
where would that be?
[22:21:16] <jepler> http://linuxcnc.org/docs/2.2/html/config_ini_config.html#sub:[EMCIO]-Section
so just add that line in the ini file?
= 0 0 2
TOOL_CHANGE_POSITION = 0 0 0
jepler:just wanted to let ya know i took the code you gave me yesterday,made a .py program with it and added a print statement to the end,now i can open emc,open idle,F5 and it prints the z pos
jlmjvm: sounds promising
it was so cool to move it,F5 and it print the position
just waiting on my friend doing the dialog box now,were shooting for a fri launch
he asked last night if there was a specific reason the tool.tbl has a tab spaced line at the end
i think he was talkin about the line that has tool 5 in it
this is the technical description of the tool table format: http://linuxcnc.org/docs/2.2/html/gcode_main.html#r1_4_1
it requires "at least one space or tab after each of the first three entries on a line and a space, tab, or newline at the end of the fourth entry."
some lines in the sample have tabs, one line has tabs
i wish editors had a "use whatever tab system is already in this file" mode
don't emacs have that?
what's it called?
that magic line at the top of the file (or is it the end?)
i think this will be helpfull to him
03jepler 07v2_2_branch * 10emc2/docs/src/ (Submakefile l2h.xsl): make cross-document references go from french docs to french docs, not to english docs

03jepler 07TRUNK * 10emc2/docs/src/ (Submakefile l2h.xsl): make cross-document references go from french docs to french docs, not to english docs
i added more numbers in between,1-25,they all work,just left that other line on the end
I don't understand what you mean

jlmjvm said he had issues with this BB and geckos http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45
It's hard to imagine that such a simple thing can be so mucked up. I'm just looking for something simple and inexpensive.
JymmmEMC:what kinda drives are you gonna be using?
i only had the problem with the 203v gecko,the 201 and 320 worked fine
[23:51:34] <jlmjvm> http://www.winfordeng.com/products/cat_brk.php
i used 1 of these for the 203v drives and it worked
03jepler 07v2_2_branch * 10emc2/src/hal/components/comp.comp: get rid of incomplete sentence in documentation

JymmmEMC:are you gonna be using a ssr to turn on a spindle?
03jepler 07v2_2_branch * 10emc2/debian/changelog: fix problem with pulley ratio reported by lawrenceg
03jepler 07v2_2_branch * 10emc2/src/emc/usr_intf/stepconf/stepconf.glade: fix problem with pulley ratio reported by lawrenceg
jlmjvm: I wanted something to buffer the signal levels, not just passive.
the drives are already oproisolated, so no owrries there too much
thinking of using a SSR for on/off
k,then you will need a charge pump also
all outputs on that board will go high when the computer turns on
yeah, LawrenceG found this neat chip by maxim
I was considering if the bb I get doens't have one that is.
