i need a good workmedium that wont eat all my bits
is there some way i can make slabs of plastic
we were talking about it the other day, let me find the link
it is 4:1 paraffin wax: grocerie bags
by weight obviously
I have not actually made any yet, but I am going to
wait, you meant like the grocery bags that me and everyone else in the world puts in a cabinent under the sink?
i can use those and not just save them up just to throw out after years
"Most plastics are usually marked with LDPE or HDPE and have a number 4 or 2 (respectively) located on recyclable polyethylene."
the deep fryer part sucks tho
and paraffin wax, but that stuff is cheap
i was hoping to use like a 9"x9" brownie pan or something
foxtrot, use your oven
you can set the temp
make sure to be VERY well ventalated
you seem a little confused by the concept.
or just a pot on a stove and a thermometer

I am trying to compile EMC for the first time, and I am not having sucess with the wiki method, anyone care to offer some help?
Why compile it?
Because I want to test some code changes
I already have a working EMC syste,
skunkworks_ is now known as skunkworks
BrianInTampa: what problems are you running into?
Well, let me start by saying that I am not very familer with Linux.
I know enough to get around, but I don't know it like the back of my hand
So, I am following the Wiki method to compile
$ cd src
$ ./configure --enable-run-in-place --enable-build-documentation
$ sudo make setuid
when I execute autogen, it complains at line 6 about not being able to find autoconf
start from the begining. did you use these directions?
[01:11:51] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Getting_the_source_with_git
actually - start here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_with_EMC2_package_already_installed
Well, I did all that the other day, I suppose I should double check to make sure everything wnet ok
Maybe I missed somehting there, I'l know after it gets done downloading...
Perhaps anyone can be guilty of a blond moment...
the build-dep got through most of it, but failed at the end, the build-essential failed immediately
404 Not Found errors.
IP 22.214.171.124 port 80
skunk, did you see what I came up with?
hmmm - what os are you using?
is it hardy or lucid or?
It was installed from the live CD
I wonder if one of the dependency sites is down.
thats what it seems like
(I cannot test it here atm)
I don't think it is anything on my side, everything else seems to work fine
only a few of the sites fail to connect
but it sounds like maybe you didn't do the sudo apt-get build-dep emc2 or sudo apt-get install build-essential autoconf
Well, I am 99% sure I did, but it may have failed then too
I can't remember for 100% certain if the completed sucessfully
I don't know - do you need to enable the universe in the synaptic package manager? or is it already?
Dunno, lemme see what I can figure out
system - > administration -> synapitic package manager -> setting -> repositories (I think)
Found it, universe was checked.
I check a few packages in another tab and reloaded...
I am running sudo apt-get build-dep emc2 again...
looks like in completed this time!
It seems to be compiling now
skunk, yooda man!
Right after it completes, I'm off to go see 'The Expendables'
heh - is that out today?
Apparently it is here...
Starts at 10:15
biab - have fun!

Hello I see that using EMC to control a CMMM is listed as a use, but i dont know if anyone has? Does anyone here know a cmm running emc?
I measure stuff with a probe in my mill all the time
especially bore diameters
did you simply touch off or does do you have it setup to calculate hole diameters and locations?
actually here's a video of how it looks: http://www.youtube.com/watch?v=eWitrmtqZ7I
have you compared the probed values to micrometer values?
bore gauge standards yes
it matches to .0001 inch
this machine has truly excellent ball screws
so it seems!
love the renishaw, excellent probes.
how much are the tips for them?
I have a .74890 ceramic standard that I test with occasionally
oh $20-40, not bad
I have not broken one yet :-)
so you wrote a selection of routines for the various shapes that you need to inspect from time to time?
this is in my calibrated probing routine. due to various errors (?) it gives me results .00025 too big. hard to say what the causes are, but I can measure it and correct for it by checking against standards
it's perfectly repeatable - often if I probe several times in a row I'll get exactly the same results (micron resolution)
... even if I move the machine and put it back
have you adjusted the screws to center the tip?
yes but it's currently .0007 off - you can see it in that video
(finding the center of a hole the machine just bored)
it's hard to get it perfect - better to measure the error and compensate in software
being consistent, then sure, compensation with software is a good way to deal with it
but it baffles me why so much. that is almost one thou.
I know at work we can probe a part 5 times and get 5 different values within +/- 0.0002
I think the probing macro moves too fast.
with emc it only checks the probe every servo cycle. so if you want full resolution you have to move no more than one encoder count per servo cycle.
for me that's 1 micron/microsecond = 2 inches/min
I think I actually do the final probe at .5 inch/min
doesn't have to move very far at that low speed because it has a quite close estimate first
good morning from wunderfull sunny Germany
ok then till later today i got to go shopping

alex_joni: On my laser engraver I need to have "air assist" - A stream of clean air blowing on/at the point where the material being cut, maybe 35-50 psi max. They want $1200 for some brackets and tubing (no compressor, dryer, regulator, etc included).........
alex_joni: I need to fabricate a way to to direct the air a specific direction, can you think of something whereI can adjust the direction of airflow, be it 90 deg straigt down, or 80 deg facing towards the rear, etc. I'm kinda looking at 1/8" metal tubing, but open to suggestions.
is it always directed in the same direction?
or does it need to move?
(you can probably use some of those tubings that are used for coolant on mills)
[14:21:44] <alex_joni> http://web.tradekorea.com/upload_file2/sell/96/S00011896/coolant_hose_.jpg
Those are probably WAY too big, hang on....
alex_joni: Take a look http://filebin.ca/ajtheo/AirAssistInstallationInstructions.pdf
I'm even thinking 1/8" may be too big
alex_joni: I need to come up with EVERYTHING you see in that doc.
within the main cabinet, not the control box.
Jymmm, you can put any nozzle on those coolant tubes
MattyMatt: No, I mean it may be too heavy to mount on the moving laser head.
Jymmm: then how about those tubes used for printer ink ?
alex_joni: I'm not familure with the ones you're talking about.
[15:13:58] <alex_joni> http://www.bikudo.com/product_search/details/128017/epson_stylus_t11_ciss.html
alex_joni: Heh, yeah a lil too thin I think =)
alex_joni: It looks like they are using 1/8" tubing (which I have to figure out how to route in the machine with no guides), to a metal tube

my new vertical mill, en route!
fully laden :)
where are the safty belts ?
they are there, just not very visible
not unlike my reply to you
I bought at a garage sale a USB joypad: Saitek P880 Dual Analog pad. Could I use it for EMC2? If not what joypad would you recommend?
DaViruz: Impressive mill, post more pix

[18:23:43] <DaViruz> http://daviruz.meeep.net/buschcncnf1/DSC_0113.jpg
pretty much all i have
Are you keeping the Sinumerik control?
i'm not sure
if i can get it to work again i might
otherwise i'll emc2 it
(i might do that regardless)
Have you done any EMC2 before or is this your first?
i have a smaller mill which is emc2 controlled
I see. I personally like EMC over any old VCR style controls
Awesome mill BTW
how much did you pay
way too little, $1000
I hate you!
yeah i'm almost ashamed :)
Was that an auction or what? Was it described as working?
classified, described as working
which it probably is, except that it's ´been left unconnected for too long so the plc program and machine data is gone
the manufacturer will send me the files, at another $1000..
Who is the mfr
never heard of them before i saw this machine, and it seems they are out of business now
You are still way ahead. I am personally really glad that my Heidenhain control was dead. I shudder at the thought that I would never use EMC.
I sold the control and it paid my cost for the milling machine
even though it was bad and so described on ebay
ichudov: maybe the emc2 panel thingy i built will fit into the existing operator panel :)

im dying here, I want a pcb layout to g-code
but I cant get it going as I want
bloody postscript files
the board layout is in a postscript file
and I cant figure out how to solve it the best
convert it to DXF
or PS to gcode http://www.chiark.greenend.org.uk/~alanb/ps2gc.html
Im running win where I am now :)
frallzor: Sucks to be you =)
frallzor: download an nix iso and install it =)
pdf to dxf works too
but I only get shitty linework then
dont think so, will probably just do the same shitty thing as the rest
bloody linework that is no good
frallzor: Gawd youre a pita, post the PS to filebin.ca
well blow me, I got it working with the AI-file
had to do something you never do with those files but it worked =P
nice outlines now
I'm trying to use a 2nd parport card set for ipins 2-9 as input.
EMC complains onstartup that parport.1.pin-2-in does not exist
etc. ... but if I take the offending lines out of the HAL file, I can start emc and the hal meter shows pin 2 is a funtioning input. What gives?
it's 02 not 2
wey it works now :)
alex_joni: Well, wth man... what if someone had 300 paraport cards, then what?! huh huh huh
it would still be parport.299.pin-02-in
The missing 0 was the only problem. Thanks!
Man I've been using my mini-mill w/o home switches for a long time. It is awesome to be able to start up, home, mount a part and go. Mo more edge finder every time I set up.
Jymmm: the limit is at 8 afaik
so it's parport.7.pin-02-in
alex_joni: Those Bastards!
take it up with Linus
alex_joni: That Bastard!
but I think it's more of a historical issue (available IO addresses)
alex_joni: Probably, as they do it the old skool way
alex_joni: Yeah! I wish I had said that!
yeah, wish you did
alex_joni: Can you think of a way to run the tubing in the laser without using energy chain?
well, there's an idea I've seen on plasmas
either energy chain, or a suspender above
like a tool balancer?
the stuff I've seen is bigger, but it resembles a fishing rod
with the hose attached
the rod pointing 45 deg. up (from one of the corners of the table)
alex_joni: Yeah, that's a lil too tacky for this. I'd do that in a pinch I guess.
I wonder how much Igus is gonna screw me on this one =)
should be fairly small Igus
and there are cheaper alternatives
Yeah, they have micro chain now
alex_joni: there are?
btw, Igus has some 2d and 3d energy chain
alex_joni: share the wealth young man =)

[21:53:30] <alex_joni> http://www.genuineart.ro/images/copex.jpg
alex_joni: I need to maintain the single axis movement, I don't want the tubing coming into the laser's path
alex_joni: Ha! I wonder how much they're selling the fishing rod for?
well i think i finally figured out homeing and touching off
i just need to figure out a medium better than packing foam sheets
my spindle is barely attached and will come off if more than a tinsy bit of upwards pressure is applied to it
is there a way to return home automatically without manually jogging it
and what is estop, just a SPDT switch to GND on that pin?
and whats the program of choice if i wanted to do like a simple engraving like 'EMC2 AXIS' style .1" depth
