only 2 more windows to go and all the big gaping holes are plugged. ;)
skunkworks_: Well gab the sawzall and make big ones!
they are already big enough
just toss a skunk or 20 in there to fill up the hole
4 4'X4' windows - 2 access doors - 3 garage dorrs
and a partridge in a pear tree
Can't wait for it to be done. soon. seeing the light at the end of the tunnel
Well, you still have to install the 400A service and wire in the 120/220 outlets every 4ft cube
Yes, even on the eceiling =)
the 52" big screen?
other than the 400 amp service. and the outlets every 4 ft. (even on the ceiling)
we don't even have a big screen in the house.
See, there ya go...

Again, are there any free-from-charge programs for creating the gcode for lathe?
its also good to learn how to do it by hand, in case you need to make conversions from machine generated code
fine 3d surface paths are very time consuming to generate by hand however.
archivist: mommy pays for a non-cheap Internet access, I would google in another situation ;)
gezar: I have made some modifications to gcode made in by means of a dxf-to-gcode conversions. I also have a book with recommendations about the optimal speeds of cutting, depths and feedrates in longitudinal directions
sweet, then your on the right track
I will write this table to a .txt-file and upload to my website and give kanzure a link
gezar: yeah. I just want to know more how-to-build and set up the machine
I don't even know what does the mill bit looks like. I used to be a student before...
you will get there for sure then, tons of resources on the net
In my `demo' gcode, 5 mm drill bit have a `standard' cutting height of 15 mm and I imagine I have a 1000x500 mm metal sheet which isn't `ideally' plain.
its always a good choice to use a spot drill whenever drilling, it will allow a better drilled hole always.
...so I wanted to mill the 5 mm thick sheets, say, in two traces with -2.5 and -5 mm depths, but the reality says we use some cheap deformed sheets and such a mill probably need a less feedrate and only one trace with same -15 mm depth
gezar: whenever drilling the holes, or at any start of the new contour? I'm using something like g00 x- y-, then g01 z-- f-
at the beginning of each new contour.
well, you want rapid g00 to position then g00 down to above material, then g01 feed into the material, yeah
so if your surface of your material varries, then you can use a min down to height, and a max back up height
that way you always avoid colisions, but you want to use a spot drill so that your real drill doesnt drift down a surface, or start to wobble
well, your talking about drilling some holes in a non flat surface right?
gezar: in a bit deformed metal sheet. In a non-flat surface, I would use g01 z- - f- with a small feedrate
and by small feedrate you want enough to keep a chip load etc, so if your in mm, you want to keep it moving probably better then .01mm/rev
gezar: what can be an XY-plane feedrate for 5 mm drill bit for 5 mm thick metal sheet of construction steel?
none, 0, you dont want to move a drill bit in any xy motion when drilling down in Z
if by drill bit you mean mill, to achieve a flat surface, then that would depened on the bit and wether or not your material has scale on it or not...
and if your talking about a lathe operation, facing, then same thing
I dont really know what your wanting to do
gezar: yeah, to drill with g95, `g01 z-5 g95 f.01'
so yeah, that feed is way too slow I believe in g95
gezar: I'm learning how to create good gcodes for XY and lathe machines
it would need to be .01*rpm=feed
if you are wanting a .01 feed per rev
hell, I think I havent programed in a few years now
i'll remember that. I will also check out another chapter of that book
gezar: are you using programs?
its important to matain a chip load, the effective amount of force on the tool
I dont use anything in all honesty, I worked as a machinist for 15 years, now im changing careers
and I have not used any g-code generating programs
"changing careers" is hitting us all
this is hobby stuff for me now
I plan to buy some car from my first salaries and also tune cars as a hobby
I actually hate computers. They're weird electronic machines.
I have to go now, have a final today, I didnt study as much as I should have though,
I live in Russia, so it will be a stock car with stock engine.

Digital Read Out
reads out from the motor and returns data to EMC2?
no. it's the position display
there are devices that only display position, which are used for accurate positioning on manual machines
`crosslide' = table for squeezing tools?
and `pulley' is a kevlar or rubber belt?
cross slide is the part of a lathe that moves the tool along the work's radius
pulley is the thing a belt goes around

Can `g01 z-"depth" g95 f1' and with a thread bit as a tool create a thread?
no, use g76
(or g33, but it's much more work)
i mean a three-axis mashine
I don't understand
holes, then another tool, and a thread like M6x1
are you asking how to tap?
is it possible on a *usual* machine (if spindle offers some range of low speeds)?
sorry, is what possible?
to create a thread using *usual* 3rd axis
I don't know what *usual* means
are you talking about a thread mill?
you can tap a hole manually, or with a tapping head, or with a tension/compression holder, or with a rigid holder (rigid tapping) in emc2
those not specially intended to cut threads after all
rigid tapping = ?
no... no... http is huge... no youtube! never!!!
only a 46 sec vid
tension/compression holder -- what does it mean? a tolerances like -100 micrometers?
archivist: no... or mom will not give money to buy some milk another day
it means the tap is allowed to move a bit, parallel to the spindle
cradek: what if I program g01 z-10 g95 f1 to move a bit 1mm per revolution?
even if that would work, how do you expect to get it back out of the hole?
to rigid tap, use g33.1
cradek: 1. spin the spindle "backwards"
cradek: what is 'rigid tap'?
that's where you synchronize Z axis motion to the rotation of the spindle
backwards + low or negative tolerances for holes, positive for rods
and you have a tap in the spindle (similar to the ones you'd use by hand)
"G33 Z-1 K.0625" is equal to "g01 z-1 g95 f0.0625", isn't it?
without moving the spindle backwards...
G33 and G1 are not equivalents
SWPadnos: no, i meant those commands
K0.0625 is a distance per revolution of the spindle. F0.0625 is a feed rate, which is independent of spindle speed
I interpret "is equal to" as meaning "does the same thing as"
and the answer to that is no
SWPadnos: g95 f0.0625 depends on a spindle's speed
oh - G95. I didn't see that
I don't kjnow taht one
"z one" ;)
What is a straight probe?
a probe moments before it crashes
what does it mean in other English words? (I have no dictionary.)
it is straight move until external switch is pressed
like tool measure button
is it syops itself?
yes it stops at the moment that switch was pressed
micges: it measures an actual tool length?
you can use a probe for many things
finding an edge, finding the center of a hole, etc
it's up to you
how does it differ from g00?
it stops when the tool reaches an obstacle?
you can use the probe more than once
you don't use a regular tool, you use a special device called a probe which has an electrical switch
the electrical switch is activated when the probe touches something
what it touches is up to you
oh... It's quite useful
can replace the use of edge finder and indicator in many cases
and i find coordinates at the DRO display or ~/configs/var.tbl or something, dp I?
you can do several things with the probed coordinates - see the documentation
Were this machines so `cheap' for example 10 years ago?
like that 4000 sherline lathe (500-800 USD)?
So, do they have same price since '00 ?
Good evening.I have a question for use the emc2 with convenzional maschine, with only one drives and 3 encoder on axis.
Many people here think these machines cost more ten years ago. have they become cheaper withing last ten years?
is possible on emc2 open the closed loop on a axis when switch the analog the another axis on drives?
motioncontrol: people usually go work from home at this hour. Few minutes ago they all was here, now they're not
ok i wait thanks
motioncontrol: if you want to improve your English very quickly and in a cheerful mood, you can ask any native human in #english channel to revise and rephrase your phrase.
one question witch select my name motioncontrol : ?
it's a nice name.
my name is my surname with first letter of my name before it.
excuse for my english. i want select your name (igalkin) , and write the message.Witch taste you pusch for slect the name?
ok, need to restart
just type the name
your irc client detects and does the highlight
normali i write the name exaple: archivist : message.exist a metod more simple for write archivist : ?
type ar[tab] and your client should complete
motioncontrol, my client adds a , and space
Good evening.I have a question for use the emc2 with convenzional maschine, with only one drives and 3 encoder on axis.the axis switch gear on only one motor. the question is: is possible open the closen loop with a hal command .because i want close the loop position only on the select axis.thanks
I would not advise that because EMC is maintaining counts for each axis
uncontrolled axes could move, you couls have a step change on moving control to another axis etc
Is this device: sherline.com/8730pg.htm is a rotary table for detail? Can one mill a wheel using this rotary table?

msg nickserv 1
not a good password
archivist: heh, have to wait few minutes or so...
yes i thing the counter is active, but i open the loop position the axis when it not move, example i have 3 encode on x y and z, but have only one motor for move the 3 axis. the gear switch on the motor with meccanical sistem.i have 3 encoder on the 7i33 card.i select the x axis.the gear the x axis is connect at the motor. the analog the motor can switch with relays on 3 analog out the 7i33 card.when i secect the x axis ,
close gear the x on the motor , and switch the relay for analog on x analog out.i want in this moment open the loop position the y anz , because if the encoder for some motive move the analogthe y or the z move up(about 10 volt) and when i swith on the y or z axis the axis move fast.is possible open the loop position?
archivist: so, did these machines have almost same price ten years ago (it's very interesting to me!)?
how the hell should I know
archivist: you're the Master Archive Man, one of Archive Men Crew!

anybody used a vision system with EMC?
geo01005, had a quick go at one with a webcam
wasnt using that no
I need the right optics before I try again, a telecentric lens
I see, what software were you using?
I used some odd (its a long time ago on another box) web cam app, just to grab pics, then add cross hairs in php and view
was for cutter centering
single edge is not the right way for touch off for a gear cutter
at the scales I work it needs some good optics, or as now trial and error
currently I cannot get optics close enough to the job and tool and use the machine
you need a camera with a good telephoto-ish lens
a webcam won't do it
telecentric, not telephoto different animal
something that can show you a narrow field of view while being somewaht distant from the subject
archivist: close to the tool center's axis?
ie, not wide-angle
whether it's telecentric or not is another story
since you probably don't need to measure distances over the entire image, telecentric is probably not necessary
(you only need low distortion near the center of frame)
any lens not telecentric has a fixed measuring plane
for measurement, that's important
for centering, it shouldn't be
I do need to write up my positioning problems
(of course telecentric is better, but it may not be absolutely necessary)
I dont know depth of cut till the tool is measured
oh. if you're aligning depth then you do need telecentric :)
for hitting the right target point, you don't :)
and the measurement should include mounting errors
(like using it as an optical comparator, of sorts)
archivist: can you apply a probe as tool #1 and manually change tools
you lot done realise Im looking for the cut width of a milling cutter and its centerline
which is a few thou wide
blank is made over size and the cutter is depthed to leave points at the od
form is http://gears.archivist.info/gears/p1010063.jpg
or more obvious http://www.csparks.com/watchmaking/CycloidalGears/parts.gif
Can I create gear wheels on stock 3-axis machines without changing the ratioby means of other pairs of pulleys
i mean, for example, a line of Sherline machines.
you need a rotary axis
archivist: what if w/o the rotary axis?
gears are rouns
archivist: the reality isn't the idealistic one
else wire erode the shape
jumpers > microsteps, othere pairs of pulleys can improve the tolerances

Has anyone repaired there oscilloscope before?
I don't, but I would left to my own devices, I probably would have a try.
I have 2 I need to repair, and they both are old and scare the hell out of me.
dont be afraid
I have manuals if you need
I have one of the manuals, the hp I dont think I have them though
I would rather finish up school and have the money to buy a new one
1250 I think,
archivist, theres one on ebay that wont power up, its a tektronix

I'm going to stop by an auction of a place where they repaired machinery tomorrow. Anyone need anything in particular that I could look for?
yeah - stuff
The ad says there are hundreds of drives and motors
300Watt CO2 laser system
one of each please
ohh a CO2 laser would be a nice thing to play with
(in a safe way of course)
where's the fun in that?
hehh well to quote an old gag, u want to still be able to see with your remaining eye
mozmck, just take a truck and enjoy yourself
hmmm. some Baldor MTE-4070-BLBCE or MTE-4090-BLBCE would be nice, if they're not too expensive
archivist - had those in front of me - just my lack of understanding with EMC/Linux in general and having no internet connection to check anything. It's sorted now apart from pulley speeds, that can wait until my annoyance level has dropped some ;)
what do you mean 'a' truck? A Fleet of trucks perhapse
and there's an Allen Bradley version of that as well, in the 1326AB series (but you have to be careful to get the DC ones)
mozmck: I could use one or more yaskawa CPCR-MR "servopack" drives
I'll write stuff down and see what I find.
pilotltd, I don't think I did a good job with the instructions for the gearchange component (like, I'm not sure I wrote any :) )
mozmck: also BT40 to JT, BT40 T/C tapping, or any other oddball BT40 tooling
what's T/C tapping?
SWP - there are none :)
did you have a hard time connecting it, setting the scale, trying to extend it to 3 gears ...?
ok - there you go
there should be an automatically generated manpage with some information
Y'all need to email him yur list, phone numbers, and dollar limits
tension/compression - where it holds a tap for driving it, but it can move up/down freely in the holder
and HNC tooling plates / tool holders
[21:03:04] <alex_joni> http://www.linuxcnc.org/docview/html//man/man9/gearchange.9.html
No problem extending to three gears, just confliciting pins and such
yeah, me too me too

I cannot believe an american watches his figure
usually we watch the figures of the other gender
do you know how to tell CAT40 from BT40? it's easy to tell, but I can't find a comparison photo
or I do anyway
mozmck, and analog servo drives that go above 80V, like 150V, 25-40 A
(which would perfectly match the Baldor motors I mentioned)
[21:06:55] <cradek> http://www.pctooling.com/catalog/Blanks/
CAT is symmetrical around the groove on the flange, and has mismatched keys - BT is thicker on the top side and the keys match
no mention of the old ISO40
mozmck: here is a bad picture of the drive: http://www.yaskawa.com/site/dmservo.nsf/link2/TKUR-5EJQ5Z/$file/TSE-C717-13E.pdf
I'll save some of that to take with me. I don't really know what all will be there. There are some machines, but I don't know if they are running or even fixable.
don't hesitate to call if I can help :-)
cradek: it seems sherline offers relatively small machines. What brand and website with machines capable to handle 1000x500x5 mm metal sheet of construction steel can you call?
igalkin, look locally
alex - the man pages don't really help me as without an example I wouldn't know how to integrate into a hal file anyway, as my struggles trying to integrate SWP's hal with mine show, chased my tail for 6 hours and gave up in the end :(
the brand (for a start)
One is a Sherline, another is ... I have forgot it
ask a dealer (for a start)
he is in Russia, we would not know your local brands
frallzor: i only want to be capable to say senceful notes to the potential employer. Here, locally, at the south of Western Siberia.
archivist: I saw two names, Sherline and ... ah I wish I remember it.
We probably have some dealers here at big cities (6-9 hours of drive on a car), but no one really cares, firms have money to buy whatever they want from whoever they want.
I didn't know anything about it, now I see I can afford a lathe "using" my mean two-month-salary. With this lathe, I could create another axis for my mountain bicycle and many other things for motornikes and stuff.
go to an evening class get experience
* igalkin buys a ticke to the American continent using half a price of a new lathe from sherline.

is anyone else upset at the tv show "deconstructed" for having horrible writing
also for being flat out wrong very often
no....because Ive never seen it :)
they take things apart and "explain" how they work
TV companies simplifying for the viewer is a common problem
but they're on like, after "build it bigger" and "how stuff works"
it's just confusing, is all
Quality show on how things work, quality show on how things work, show for third graders
just tried to make a test mandrel for a chinese ER16 BT30 holder, it would help if the lathe I used could turn parallel error is 1 thou in 500 thou
made another, learnt a bit about how far into the er collet the mandrel has to be
+- 1 thou at about 3" probably ok for cheap chinese tooling
