?? Mentor_ ?? interested in EDM?
re: " <SWPadnos> if you want to back up for EDM (or similar) purposes, then there are probably other ways to accomplish your goal"
SWPadnos whats your thoughts on reversal between trajectory updates (in EDM, during the approach to one destination, the progress may be fwd/bwd/fwd according to the process)
this is much finer than the coarse idea of reversing a gcode line, it is as fine as one servo update
btw: flukes suck as scopes. a meter aint a scope. a digital scope aint an analog scope.... et infintum

whats the differance between a 10mhz oscope and a 60mhz oscope
thats the 3db response that the makers quote
all depends on work you are doing, I prefer the faster
im lookin for a cheap but ok quality digital oscope/multimeter

damned expensive for hand held
archivist, you have one?
not a hand held but do have other scopes
can you give any tips on buyin one maby?
most recent I got an 8 channel on ebay
how much was an 8 channel! lol
less than you think :)
I have an advantage in knowing what the item was, the description was wrong
tek is one of the best
digital or analog?
top 3 makes are Tektronix, LeCroy and Agilent with Fluke also making handhelds (includes the old Philips brand)
Owon and others are chinese
ewww chinese junk
even the best are getting stuff done over there
I get second hand because I can test and fix, and its within my price range
if you see a good deal on an ebay handheld scope meter please let me know!
far cheaper than the one you were looking at http://cgi.ebay.co.uk/UT81B-portable-Scope-Digital-Multimeters-8M-bandwidth_W0QQitemZ280242794076QQcmdZViewItemQQptZUK_BOI_Electrical_Test_Measurement_Equipment_ET?hash=item413fc5ae5c&_trksid=p3286.c0.m14
GammaX, you are in the states? where
not in the states currently...
ill be back in a month or so hopefully! lol
if I had spare money and the need ebay item 360169077362 way over the top for you as well
what would that be used for neccasarily?
I cant repair that lol
Well I might be able to but is it worth it?
for spares if you already had one
im basicly gettin an oscope for my milling macine and an other general thing I run into.
for mechanical work probably enough, dont forget halscope built into emc
id rather have a physical oscope
and I need a good multimeter so I figured buy a scope/meter
weil irgendwie wird das ding in letzter zeit extrem heiss und der lüfter läuft dauernd

i like the loldogs ones too
I have a set of favourite pages in firefox ichcb is always there
skunkworks_: worst slinky ever
He sure knows how to sleep
He actually looked up when the camera beeped - but decided it wasn't anything important (food) and put his head back down.

I cant make up my mind on what multimeter to buy... I am thinking about the fluke but I am also thinking about buying a lesser known scopemeter
one of each ?
thats possible but Id rather have an all in one...
GammaX, you asked what kind I use - it's a Radio Shack meter
SWPadnos, seriously? lol
I have an HP benchtop meter as well, but I usualy use the Radio Shack
why dont you have a fluke with all your big bucks? haha
and I have the HP ;)
[17:02:45] <cradek> http://geektrap.com/bill-files/01248711886/dscn7531.resized.jpg
you can see my favorite meter here
looks like a Simpson
no, it's also a radio shack
or any other one of that era :)
fetvom (I think all the simpsons are passive)
an advantage of a meter vs. a scope is that you don't have to worry as much about grounding
yep, or plugging it in
What is up with all you guys using radioshack devices? lol
GammaX: they used to be good
he wants a scopemeter
I bought mine about 7-8 years ago, and it's a digital meter
often, the more functions a device has, the worse they all work
cheap shit for bench work
has a serial port too, but I've never used the datalogging features
I wouldn't blindly buy a no-name scope meter thing and expect it to be usable
if you're trying to measure milliohms or microvolts, they're not so good
for most other things, they're fine. who cares if the 24V supply is 24.00000 or 24.01V?
I think my scope is 20 years old too :-)
damn. You scope is almsot as old as me haha
some of my scopes are older
yeah this is my "new" one, haha
finally have one with no tubes in it (except the crt of course)
I have one of teks early transistorised with sampling plugin
I am also thinkin about getting a pair of smart tweezers for electric repair
my scopemeter is 20 years old, which is a bit newer then my crt scope..
the scopemeter is pretty amazing for it's age though
well what would you guys recomend? I need a good multimeter and I want to get a scope...
if you were involved in last nights conversation please remind me as I was accidentaly tripping out on ambian haha. I was trying to buy a scope meter and couldnt see the keyboard lol
last night, you mean this morning
summary: scopes are expensive.
uhmm Wierd time differance.. I dont remember
can be cheap on fleaybay
Im open for a used one on ebay if it is suggested

Britain is a police state...
its an over taxed state
i'm not sure comrade brown would agree its a police state, more like a dictatorship
pjm: i reference your machine a lot. :)
its doing ok at the moment, still churning out pieces and bits
i'm looking at the MESA stuff currently
That would sure be a nice upgrade
there are a few brits needing mesa stuff, was talking on the phone to some earlier
i reckon i need to go for a 5i20 + 7I47 to control 4 X steppers, have limit switch inputs (xyz etc) and spindle encoder
i'm slowly replaceing my microswitches with inductive proximity switches
i'd probably order the cards via my proxy in atlanta
[17:58:53] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=86610&page=2
I don't see how you'd need a 7i47 for that
Ive run out of connections for switches
7i47 is differential IO
(I was being just a little mean)
cradek only because i'm too lazy to design and etch up a suitable I/F for the 5i20
i reckon i should have a 5i20 for all control related stuff but keep the parport for the MPG pendant
skunkworks_: even with the stepper rig-up thing he's using a springy holder
and then peck tapping with a springy holder - that can't be a good idea
he has straight fluted tap!
hm, the 6" kurt is on sale for $409 with free shipping...
I just love the comparison
cradek: are you planing on adding a few axis to jr?
trunion or something?
sure looks like it has decent z travel remembering sturats shop.
yeah it has maybe 18"
it would have to be small
you do need some XY travel with a trunion
wednesday the 12th we have "Think Your Drink" training at work
must be a follow-up to the salad training we had last month
* cradek sighs
ew, strange company
seems like a very touchy feely company.
not for rough blokes then
fortunately (so far) all that kind of thing is optional
'what is your stapler thinking?'
can you believe 'office space' was 10 years ago?
they still have them
I know - seinfeld also...

skunkworks do u reckon the write up of my machine on the wiki needs any additional details? I think it may be brief in some areas..
skunkworks_: he's so creative he could do some amazing things if he'd use emc instead
yeah hoss is a master
he's my hero
i'm currently building a belt drive for the spindle on my X2 using hoss's plans

cradek: whats so special about a red stapler?
seb_kuzminsky, how is your mill project going?
Jymmm: it was an important part of that movie
geo01005: slowly :-/
cradek: oh, guess i missed that part of the conversation =)
seb_kuzminsky: that is ok, I haven't touched my mill for weeks.
i learned how to grind flycutting tools and trammed my column and flycut a 6x4" Al plate
that's some kind of progress :-)
4" sounds pretty wide
it made a huge mess - nothing like a hot swarf shower to wake you up
* Jymmm is still watching all these videos of that tool changer
yep nothing like a flycutter to fling chips around
makes me want a cnc-converted machine, just so i can enclose it ;-)
cradek: how's your mori-seki?
X homed last night
so, I think the hard stuff is done, it's just a matter of wiring it all up and writing ladder
figuring out how to come out of estop took some reverse-engineering
you're using 5i20 with servos?
I'm trying to use all the existing setup minus the old computer
5i20 + 7i33 + some opto22 stuff
7i33 is pwm to +-10?
yes, and differential encoder receivers
4 channels of each
index on the encoders?
yes of course :-)
homed X to index
* seb_kuzminsky drools :-)
about .0004" backlash in X - hard to measure for sure - almost none
I hope the rest are as good
preloaded double-nuts on the ballscrews?
yes, surely so, although I haven't seen one yet
they may even be adjustable for wear (with shims)
is the table and head on dovetails?
no, it's linear rails
wow, nice machine chris
yeah I hope mothing major is wrong - it's good so far :-)
Fuuuuuck, that project started from a HF mini mill ?!
Jymmm: well, a couple, i think, but yes
[19:57:30] <Jymmm> http://www.hossmachine.info/images/IMG_1226edit_800x600.jpg
Is the spindle in the HF mill that good???
the column seems too narrow
[20:00:36] <Jymmm> http://www.hossmachine.info/images/IMG_0645_800x600.jpg
anyone here working with solidcam?
[20:03:58] <EbiDK|AWAY> http://abstrusegoose.com/171
has any one throught about adding a M19 function for spindle positioning
or should the spindle be treated exactly as an axis like A or B rotaries
any one here, who can give me an crashcourse in solidcam?
M19 Sxx is standard to postion spindle on mill or lathe
i used it very long time ago numen should be some tutorials in help
Heh, that ScopeMeter even has an analog scale in the sw.
robh_ i allready tried :(
is it demo or full
demo i not tryed maybe they took them out
full used to have them in help menu or as PDFs in install folder
im sure theres website some where that has tutorials
my problem is the english :(
menus i found pritty ok, if u understnad machiing u can use it to some exstent for 2.5D 3D takes abit more button bashin
any one in here around when they did the mazak? did its spindle drive take -10v - +10v or was a new vfd fitted for it?
I don't recall if it's the original or a new VFD, but it does take 0-10V for speed commands
I'm also unsure as to whether it's +/-10 or o-10 plus direction inputs
was just looking at demo config file to see how they closed spindle loop on tool change location
it's pretty slow PID - the response of the VFD isn't so hot
as all VFDs on my mills lathe etc are 0 -10v only with fw,rev inputs
that's no bug deal. EMC outputs a signed number to HAL, which then deals with it however necessary
spindle drives need realy are but only need a 2/3degree window realy to change tool, or turn a touch probe to probe
you'll have issues if you need to flip relays, but optos should be OK
i see with the spindle drives that have the orientation cards in our mills also they do is switch from fwd rev to hold a postion in window as no torque at low speed on spindle
on my leadwell i refitted it just had input for spindle orientation which takes care of it all for you. but as the drive is now down/not working just looking at whats around to replace it if i cant fix the dam thing
Jymmm, it looks slow and low res to me, but you know me
SWPadnos: Well, it's not a $50K scope =)
Jymmm, im lookin at those 2... I want one but im affraid it will just mess me up... since I know nothing haha
SWPadnos: Is it better than nothing (for what it is)?
Jymmm, have you checked out the other kinds on there? there was a better model I saw for around 400 I believe. BUt yet a gain I dont know anything about them
SWPadnos: I really don't have a NEED for a scope, but having one around might come in handy once in a while. I want to play with uC eventually as well.
GammaX: I've seen the others, I'm just looking at cheap. Like I said, I don't NEED one.
Jymmm, im in the same boat as you. Although I realy want to get an extremely nice multimeter... possibly a fluke and another non portable one for smt repair
Is creating a DXF creation lib worth while?
or just ue exiting tools to convert from svg to dxf?
so i have an e-stop switch wired to the enable pin on my servo amps
check the command voltage with drives disabled
enable the drives, and one of them spins up and the command voltage reads ~0.5 volts
what happens in the wire to the amps gets cut?
was thinking ground loop
goes your e-stop switch kill the spindle too?
on the amp, it has a not enabled pin
So it's more of a stop button, not a EMERGENCY-STOP?
when you ground it, the drive is disabled
yeah, right now it's a servo amp on/off switch
Sorry, it's jsut that ppl use the term "E-STOP" ambigously. When they really mean an "oh shit" button, and not a "Somebody s about to get seriously injured" button.
well mcmaster doesn't sell oh-shit buttons
No, ppl should consider EMERGENCY STOP for what it is, in case of emergency, not because they or something screwed up.
yep, was ground loop
was using shielded twisted pair on that command wire
had it grounded on one end
Estop is just a glorified limit switch... in my case atleast
just cut it, problem is gone
well i guess that's not technically a ground loop
mikeggg, you can hook it into ur controller board and make that the reset...
thats what I did
right. just ordered a 7i37TA for that yesterday
nice. Is this a retro fit?
my company is developing a machine tool
though I have an old south bend lathe in my dad's garage I would love to convert
anyone know how to run the m5i20_pidtest.hal?
HAL: ERROR: thread 'm5i20.threa1' not foundm5i20pidtest.hal:25: addf failed
it's throwing an error
if that's pasted in (rather than trasncribed), then you have some errors in the files
it is pasted
then something is terribly wrong. The formatting of the erorr message looks wrong to me
(I'm pretty sure there should be a space between the word "found" and the name of the file, m5i20pidtest.hal)
ah, there is
so much for copy/paste ;)
well that was my bad
copy paste put a strange char in there
in my haste i didn't get the space back in
and the "m5i20.threa1" - is that correct?
did you copy/paste when downloading the file?
which file m5i20_pidtest.hal?
not actually sure where I got that....
me either. I'm looking for it now
might have been anders wallin
i put some stuff in the config directory that displays sliders for the following error
but those don't work yet
wiki or are you using the hal_m5i20 driver or the hostmot2 driver?
this file: http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob_plain;f=configs/m5i20/m5i20_pidtest.hal;h=da068f92390bee01b42ed5b193dd1af7d72385b2;hb=HEAD
is for testing with the old m5i20 driver, not the newer hostmot2 driver
the file is included in the distribution (in the m5i20 sample config directory)
right, that's it
you have typos in your file if the error you pasted is correct
went through the front end and chose the m5i20 servo sample...then told it to save the config files to my dir
oh, that is loading the m5i20 driver, not hostmot2
both of them
how do I tell it to use hostmot 2
and there's no 1 in the thread name in the file on the web, so the one you have is wrong, or the error is incorrectly transcribed
it would need some editing to use hostmot2. all the pin and function names are different (hm2_pci.xxx), and I think the watchdog has different requirements
