Now here is a nice picture of the spherical seats. They must use a ball-shaped cutter. http://www.kurtworkholding.com/double-lock-vise-replacement-parts-dl600a-replacement-parts-c-43_44_101_74-l-en.html
It seems I could buy a new jaw for $670. I can see why the vice is not selling, it is just a paperweight without £1000 of parts.
louipc: There is one of these on eBay for £30, but without the jaws (just the base, screws and actuator) http://www.kurtworkholding.com/manual-doublelock-vise-p-1110-l-en.html
They seem to trade a bit on "Made in the USA by Americans" which doesn't have quite the same effect on my purchasing decisions.

skunkworks wanted a tool change video...
I think I'm more interested in touchy than the tool changer
every time I look there are new emc videos!
like this one - not a trivial retrofit - http://www.youtube.com/watch?v=2RFX2b5otcA
it's having sex at 1:15
lots of lube, but no protection
the stage of a retrofit where you wonder what you've gotten yourself into
cradek: Not as bad as this (DO NOT skip the intro)... http://www.patchsee.com/
cradek: Yeah, novel idea. It's how I test fiber cables.
did you see my new video?
[02:11:30] <cradek> http://www.youtube.com/watch?v=eWitrmtqZ7I
Nice, is that your new toy?
I've had it about a year?
the tool charger sounds like a Transformer (tm) lol
(the robot that turns into a car/plane/etc)
the megatron tool changer?
What did you use for a probe?
it's a renishaw
ah, thought you made one.
nope it's a commercial one. wireless
really, I'll be damn.
so too much interference and probe crashes?
otherwise it couldn't go through the tool changer
ds2: no, if it loses signal, it tells the control it's tripped
making a contact probe, how would i use emc to test its repeatability?
probe a bunch of times and compare?
problem is you're testing your entire machine's repeatability too
though with the linear scales it shouldn't be too bad
yes if you're careful about how you do the test
big block going back to Z axis moving a mm or so off the switch back onto it
(our Y axis is better/smoother than Z)
where would I start looking at probeing?
you mean building a probe, or gcode, or ...?
gcode and EMC side of things
I posted the gcode I use here: http://timeguy.com/cradek/01262579508
and you can find gcode docs from the good ole quick ref: http://linuxcnc.org/docs/2.4/html/gcode.html
thanks lol there was a whole bunch i didn't recognise
I just do simple things with probing - hole measuring/finding, edge finding, distance measuring
how would i get the co-ords out of it when its tripped?
you could do much more
by reading the docs!
we are making a tool length measurement doohickey
but the docs are hard
from the gcode quick ref click on "G38.2 ... straight probe"
yeah i can see it sets the variables
but how do i get it to tell me them?
that's how you get the results
print out somewhere
oh I see
you can log to a file, or display on the screen
sorry i didnt see probeopen and probleclose
(debug,I probed at X #5061 Y #5062)
that would be very handy
we could make a little gcode doohickey to probe a thousand or so times and then manipulate the data in excel
at the end of my video that's how it shows the diameter and hole location
yes you log a bunch of trials, and calculate the mean and std deviation for instance
or open office? ;->
just spotted your pocket putty as well, that could be handy
key them into your hp calculator if you want
I had a sharp DAL back in the day
nothing so fancy
would be handy if you distributed it as a bare cab perhaps?
ah, I don't know much about that
got your name on it lol
I mean cabs
it's just one file, you run it
easiest install ever (none)
it runs direct on the device? thats handyer
(normally when i see a .exe for a windows mobile, i assume its an activesync installer)
ah nope, it's just the program
only other thing i have noticed with the origional but don't know if its an issue with yours is when you connect to a new server the "do you want to trust this" pops behind the window itself
I haven't noticed that problem
no it looks all good with yours
you are a ledgend

its a meme
no, it's marketing
when you can get 100,000 people to voluntarily watch an add and laugh at it your doing pretty well
will old spice blend?
now theres a question
their channel is most viewed today on youtube
with 82000 subscribers
you couldn't pay for that (although they have, which is interesting)
now to learn enough hal to get the probe working ;->
anyone here have a pair of safety glasses they really like?

alex_chally: I got some from our local hardware
more like sunnies
dpeends on the way conditions. If I could still see the scraping I would probably buy em
(i actually got them to use as sunnies)
Valen, I have been thinking about finding a nice set of replacement lenses (that will be cheap to replace) and then building frames around them
* alex_chally was thinking about integrating a set of LED lamps in them, aimed at the focal point of his flip down loupe
these were like $10
lights on glasses seems like a not so good idea 90% of the time to me
I seem to wind up using shadows to see stuff
the other 10% it'd be indespensable lol
Valen, i would not do it unless it was very low profile
I think I could probably nest a 500mw white LED in one of the arms, and then stash the batteries in my pocket with a cord (I already have one cord for headphones going into my pocket under my shirt all the time in the shop anyway)

* JT-Hardinge wonders what effect having the tool radius instead of the diameter in the lathe tool file has on the control point :?
redwizard-kde, so where in the UK :) /me is in Burton
jthornton: if you use cutter comp, arcs and tapers will be slightly in the wrong place
cradek: thanks, I don't use cutter comp... yet
then your arcs and tapers are REALLY in the wrong places :-)
but have the new habit of reading closer
I have been wondering about my arcs being off
for example a straight cut on x and z with a small arc <0.015" on the corner without cutter comp there was no arc...
* JT-Hardinge opens up the manual on cutter comp
* skunkworks_ never had a controller that had cutter comp.
if using a normal radiused turning tool, if the arc is smaller than the tip radius I don't think the tool will touch the corner
the controlled point (which is completely outside the tool) will be what makes the arc if you don't use cutter comp
run without and then with comp and compare the backplots - you'll be surprised how different they look
so if I touched off on the radius of the tool for x and z but didn't adjust my touch off to the center... I can see now why the small arcs are off
and with an "upside down" lathe like mine the cutter comp will be like arcs and "seem to be" backwards
yes beware "on the left" and "on the right"
I think you'll want G42 for front side turning
I just lay on the floor and look up at the ceiling when I program arcs
and yes you could touch off for the center of the radius, but it'll be a constant pain
and G41 for front side boring
I'd rather get used to cutter comp and see how well the manual explains it :)
dang my little dry marker status board is running out of space to put important notes
skunkworks_: did you see http://www.youtube.com/watch?v=eWitrmtqZ7I
Darn, it won't cut my radius because it thinks it is an inside corner but it is not...
what's the error?
Tool radius not less than arc radius with comp
you're on the wrong side of the arc then - if you're outside it, it doesn't matter
lay on the floor some more :-)
ahh my back does feel better now :0
cradek: thanks! that is awesome
JT-Hardinge: that's not your entry move is it? I see there are two ways you can get that error
inside the compensated (but not entry) arc with tool rad < arc rad, and ANY entry arc with tool rad < arc rad
I was not sitting behind the spindle on my back so I chose the wrong comp... the bore is from inside to outside
inside bore going +Z to outside facing +X?
that's G42, G3
yes g42, g3 boring
with an angle step inside too :)
gcode is hard! </barbie>
it's easy once you know how :)
skunkworks_: my videography skills are not very good, but at least my camera autofocuses so you can kind of see what's going on
* JT-Hardinge needs to stop reading the forum and make some sparks or chips what ever comes first
cradek: I think you did a great job. Gets the point across. :)
cradek: kinda got off track... http://www.practicalmachinist.com/vb/robots-automation-new-forum/would-you-consider-mach-3-simple-machine-automation-206575/
the neat thing about http://www.youtube.com/watch?v=qeQ2rooVrPU
is the coolant nozzles don't move with the head, so different length tools don't mess them up
I didn't notice that the first time
hmm - interesting. I don't know if that is good or bad... Cause it doesn't move with the table also.
that seems good, because it stays at the spot where the tool is cutting
does it make any sense to use cutter comp for just straight line boring?
cradek: you are right ;)
JT-Hardinge: I'd assume if you are boring a hole, something has to fit in the hole too.
sometimes just a clearance hole
Then I'd suppose not, especially if you aren't using tooling with 30,000 hours on it or from HF =)
JT-Hardinge: the resulting path will be the same, so it doesn't really matter
ok, just wondering
I did notice that to do a bore you had to move > the tool diameter on X to make your retract move
this is so much fun :)
yes you have to be careful with retracts etc if comp is on. think of the tool tip as a round tool, and think about keeping it on the correct side of the programmed path (even on rapids)
it's easy to forget to think about those corners as corners
that is what I did think of it as a milling tool to sort out the error I got and then it made sense
Q: If you burn something, does that release CO2 ?
erm depends if its carbon based no?
Ok. What if you have a very hot light with a cooling fan; Is ANY CO2 produced just in the cooling factor?
likes those kind used in gyms or stadiums
I guess I should say concentrate the CO2 by burning off O2 due to the heat involved
gah my steppers that work alot becomes very hot very fast:/
steppers are supposed to be hot to the touch when used
sounds not good =)
if you drop water on them and it boils, they are too hot 8)
actually, water boils at 100C, and motors can often go to 150C, so boiling water isn't even a good indicator :)
maybe if solder melts on them or something
I think if the case gets hot enough to melt solder - the connections within the stepper are suspect...
probably - so it *is* a good indicator that something may be wrong :)
feels like the isolation on the windings would burn off ?
if my motor was rated 150C=death and it was operating at 100C I'd already be worried
so maybe the water test is still good
well, anyway, if water
[16:20:36] <Jymmm> http://pagingdrgupta.blogs.cnn.com/2010/07/15/romaine-lettuce-recalled-in-u-s-and-canada/?hpt=Sbin

cradek: what is the part for?
Fox_M|afk is now known as Fox_Muldr
this is odd, if I have a program that starts with tool #8 and #8 is all ready loaded it doesn't run past the load tool part while other stations do not have that problem...
is tool 8 loaded (emc knows about it because you previously loaded it) or is it just that the turret is at position 8 when tool load is called?
tool 8 is loaded from the last time I ran the program
I think M6 will always do the move to tool change position, no matter whether the tool is already loaded
no idea why 8 would act differently except if it's something in your ladder
that's what I'm looking at now, it doesn't seem to start the ladder logic step 1 for some reason
I have my tool change request bit connected to a counter but it doesn't increment
I can request other tools and the counter increments once each time
so I know the counter works :)
I did a t1m6 then t8m6
looks like iocontrol.0.tool-change is not coming on when T8 is called when T8 is current

cradek: is that a renishaw probe?
yes an old model
cradek: what is the plate for?
I'm embarassed to say that it's going to be part of a sterling engine (if I actually finish it)
aww - neat.
That is one of the big plans for the K&T when it is up and running.
multi cylinder stirling

skunkworks_: final part: http://timeguy.com/cradek-files/emc/yoke-pivot.jpg
a T0 M6 seems to make it work... now back to why can't I cut a 0.010" radius on that edge
I cut a lot of stuff that way: leave .003 of material at the bottom, cut full outline, whack with dead-blow and it pops out, with luck the flashing comes off with a deburring tool, otherwise file
hmmm, my corner radius is 0.03125 so my "diameter" in the tool table is 0.0625" so that seems correct...
* JT-Hardinge looks to see if orientation "7" is correct for that
looks more like 3 than 7
I had the front and back angle correct for orientation 3 but had 7 in the tool table... we will see if that makes any difference on this scrap part
strange - I thought the orientation picture was in the tool shape compensation help
it's in the Lathe section
yeah I bet it's 3
yea, that shows a way different tool path
fire in the hole!
hmm, looks like a 0.0075" radius but I'm happy with that
oh, I started 0.0025 off the inside wall with my radius :)
one last op and I'm ready to run parts
what's it supposed to be?
cradek: if I had your mill I would make a whack load of 'useless' models ;)
JT-Hardinge: oh the path is right now, but your offsets were not quite right?
everything is right now, I started the arc 0.0025" off of the wall so I wouldn't leave a mark on it :)
my insert info doesn't tell me the included angle for a trigon insert... off I go looking so I can get that tool set up correctly
(it only uses those angles for the picture on the screen...)
aren't trigons 80 degrees?
I think so
yep iscar had the info they are 80 degrees
* JT-Hardinge is ready to trade jobs with myself and be a button pusher/part loader for a while...
We have a plasma cutter and I was wondering if this software would possibly be a viable option to run it.
Or is it more for mills?
EMC is what I run on my plasma cutter
and my lathe and...
emc controls motors. doesn't matter what it is. robot, mill, lathe, laser, waterjet, fishing trolley... if it needs a repetitive task done accurately, EMC can do it ;)
Ok. Reason why I was asking is the pmac board on it seemed to go out and I am looking at options to run it.
It used to be a waterjet that was turned into a plasma cutter by about 3 different people that no longer work here so it is being a royal pain in the arse.
fun times :/
servo or steppers?
Not sure. Ill go check. (The parts we have been working on don't really have need for us to know.)
EMC can control "dumb" hardware like step-direction drives and servo amps that take velocity and direction etc.

maybe you could find specs for the servo amps online.
Yes. It drove us batty for a while when the wire came out and the only photo was before it got rewired.
Also. Is there a better channel for general CNC questions rather than ones about EMC specficly?
not sure. we're pretty tolerant of general cnc or machining questions here
we dont bite much :)
we don't get too huffy unless someone wants help with their mp3 player or nonfree software

is anyone else getting the parport mode 4 error since upgrading to 2.4 ?
I just swapped over to another newer Dell, and I still get the error
some dells seem to have this problem. if you update to the latest 2.4 version it is changed into a warning instead of a fatal error
We have at least one 14" monarch from1950. And a few other lathes that people are useing so I can't really go randomly checking but are the same era. http://i29.tinypic.com/14izais.jpg
prior to 2.4 it wasn't a fatal error though.
mikegg: 2.4 uses an entirely different approach to finding and using parallel ports
yes, nice machine
ah, ok. cool. I can surely live with it. Just frustrating when you swap boxes hoping to make an error you otherwise know nothing about go away, and it doesn't :)
what 2.4 version are you using?
welcome to the wonderful world of compter/electronics diagnosing.
maybe that is not the only error then. pastebin?
are you using ppmc or hal_parport?

I seem to be falling at the first fence with this Atom board. I don't seem to be able to get an OS onto it.
well this has been an EMC edumacation today... and parts are flying off the lathe all the right shape too!
I hav tried 8.05 and 10.whatever
JT-Hardinge: funny that you wrote the docs on cutter comp but had never really used it
I think I finally have it booting from the USB drive (had to tell it to treat USB drives as hard drives)
yea, I really didn't have any machines that it was useful with
I've been using it more and more, like for cutting around that part I showed earler today. it's really useful.
that does make it hard sometimes... I used a sim when ever I could to try and make sense of it all
I still wonder why it waits for a spindle-at-speed before a M3 is programmed...
and not after
I gotta go read the docs...
before the first feed move after each spindle start or speed change;
how do you simulate a milling session?
maybe that will help me
tool change causes spindle off = speed change
your g1 is the first feed move after that
i keep breaking my machine because i miscalculate offsets
so it waits
Fox_M|afk: simulation won't help you much with that
foxtrot, I test parts of my code on the machine without tools and parts
so is the tool change wrong or is the assumption that the spindle is running after the tool change wrong?
foxtrot: use maxvel limit to control the entry move of a tool the first few times after you mess with its offsets
JT-Hardinge: neither, IMO. if emc says spindle off, and your spindle is not turning, your setup ought to be asserting at-speed
foxtrot: after I set up my tools I first do a chicken check to make sure that when I load the tool and move it manually to some spot where I can expect a certain position on the dro then see if it is real close
I slow down the entry move and pause it an inch before it gets to the work, then I look at DTG and see if it says about an inch
this is very easy with touchy (plug plug)
and use G4Pn to give you time to look at the tool and see if you got things right
IMO you simply have to check that offsets are right the first time you use them. it's foolish to trust a new offset and let the machine rapid
for gear cutting my touch offs are in a sensible sequence so I know its in the right ballpark
unless it's a very slow/weak machine anyway :-)

attach it to the center of the flywheel
this is a push mower right? and no electric start right?

You could potentially swap the stator for one from a scooter or offroad bike that has a seperate coil for lighting.
