Gamma-X: I would not buy braking resistor without knowing the wattage and resistance that your control requires for you motor. After looking at what mine requires and what is out there it is all over the map.
Mine is looking for 100 Ohms at 150 watts for 2 hp 10%. The next controller is 200 watts and 75 ohms for 3 hp 10%. happy hunting.
so guys how do thread mills work
i just like, puts the cutter into the side and helix down at same pitch as screw?
and this means i would never have to tap a hole again?
usually you start at the bottom and go out, but yeah
drop it in at the center of the hole, turn on cutter comp, move out to the edge, and then loop a bunch of incremental full circles with the Z depth as your pitch.
does anyone know a possibility to use my inventor part files on emc2?
via a cam program of some sort
[09:36:45] <archivist> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
are there any free cam programms?
that page I just linked has mostly free, but free cam is in its infancy for complex parts
thes are just not very complex 2.5d parts
shall i show you an example?
is it possible, to add a cam like these ones direct in emc?
there is a new program being developed HeeksCNC
where to find?
works on win or on linux?
thx looks nice
but how does this work?
how do i create my gcode file?
Im not using HeeksCNC, Im helping with HeeksCAD only at the moment
i opend my stl file, but how can i select a sketch? this is not possible...
there is no sketcg in an stl file
but with step or iges file, it does not work, too
can you help me, if i provide you an step or iges file?
its early days add comments on the mailing list
like I said i have NOT used heekscnc
you can ask in #cam, the authors hang out in there at odd times of day

I have 2 questions about emc2...
first: emc2 can move reverse program ?
is someone here?
sorry for my english
Mentor_: the whole program? or just one-two steps?
whether the program has an option "reverse/forward program"
about 100 steps
only one-two steps ?
first, EMC doesn't run on steps, it runs on positions
why do you want that
step/dir is just one of the outpt options
I rerun after an adjustment
I meant step as a g-code line
if you want to back up for EDM (or similar) purposes, then there are probably other ways to accomplish your goal
but if it's a couple, the answer is no
if you want the whole program run reversed, that might be possible (by parsing, and inverting the file :D)
i have machine 4 burners
when one turns off the burner, I have to withdraw the
then i need reversed program ...
to this point
in Mach is the option, but it has errors
:( not good
a string processing program could produce reversed programs
depending on how they work, due to the burner on/off and any o codes

There isn't a way to rectify all three phases of a 208/120 source to get 120*sqrt(2)VDC...
no, it would be 208*sqrt(2 I think
Yeah, you can get sqrt(2)*120 from each phase, but you can't put just put the rectified voltage from each phase in parallel.
Cant you just use the + 3 phase bridge output relative to neutral?
why not OR them together with a diode?
[21:55:52] <SWPadnos> http://www.allaboutcircuits.com/vol_3/chpt_3/4.html
you do parallel the outputs of each phase
rectify then a series diode and parallel that
thanks PCW, I didn't think about that.
is 120/208 delta or wye?
only if you have access to the neutral
Well so it is a delta to wye transformer.
So I do have access to the neutral.
I wish I had time to take a bunch of EE classes.
You just gotta love git!
git-svn clone svn_url<enter> done
thanks again guys :)
git has a svn emulator now?
Probably not the best for high power because its basically 1/2 wave per leg, there may be some significant derating
ds3: always has, and cvs too
oh nice, didn't know about it til now
now if it only had it for hg
Yep, so even if projects use cvs/svn, you can still use git and they have nfc.
You can even import into imap folders
imap is taking to too far :P
PCW, you mean derating on the bridge rectifier?
ds3: Nope, you can do checkin/out via email.
git spam :(
anyone know a good site to buy electronic supplys . I want to buy a good meter..
* bill2or3 got his on ebay.
Gamma-X: can you be more specific?
www.jameco.com carries fluke meters
handheld? $100? $400?
on the extreme end is the HF $2 meters
handheld, sumtin with a lot of options.
I wonder if i can get a fluke that has a built in osiliscope that is handheld! lol
Gamma-X: Yes, it's $3000
I think so, but probably > your budget.
ok well i want something that will lastmaby under 400
[22:10:09] <Jymmm> http://us.fluke.com/usen/Products/Fluke+190.htm
fwiw, I got a 116, I've been happy with it.
wow the 190 series is rediculous haha
I want somthing not so expensive haha
[22:12:23] <Jymmm> http://www.amazon.com/Fluke-FLUKE-87-5-Digital-Multimeter/dp/B0002YFD1K
Jymmm, anything that much beter for an extra 100 or so?
Gamma-X: I bought my Fluke 7 eons ago, and still going.
here's a tiny scope for you: http://www.seeedstudio.com/depot/digital-storage-oscilloscope-with-panels-p-167.html
Check out flukes atalog
bill2or3: that's kinda cool
I got the kit, mostly just for fun.
Gamma-X: Did you want a scope?
bill2or3: how is it? How do you calibrate it?
my smd soldering skills are much better now. :-)
Jymmm, I do but I havnt even looked into them yet
Gamma-X: Are you going to be doing mostly bench stuff?
for the o scope bench
or atleast close to a bench haha
ask SWPadnos about this http://cgi.ebay.com/New-Digital-Color-Oscilloscope-OWON-PDS5022S-w-USB_W0QQitemZ130318650557QQcmdZViewItemQQptZBI_Oscilloscopes?hash=item1e5798ccbd&_trksid=p3286.c0.m14
that looks not-awful, a lot smaller than what I've got now.
the specs say it's a piece of shit, but I've never touched one
PCW, I see that. Do you think there is any way around that?
SWPadnos: I new player on the market it seems http://cgi.ebay.com/Digital-Oscilloscope-Rigol-DS1102E-100MHz-Color-USB-2CH_W0QQitemZ120414328892QQcmdZViewItemQQptZBI_Oscilloscopes?hash=item1c0940d83c&_trksid=p3286.c0.m14
* bill2or3 wonders about the quality.

320x234 resolution? that's about like my phone
which? 1, 2, or 3?
what I Realy need is dynamic break resistor
you need to get within 1000 miles ofthe machine first
* Jymmm hands Gamma-X a 50lb bag of salt and bucket of water.
3 has teh same display resolution
Another transformer is probably the best option, maybe SCR bridge with phase control?
SWPadnos: Ok, so back to the Owon then?
no. wait for something useful to show up
PCW, I suppose I'll just use a single phase transformer then.
SWPadnos: Oh, they show up, but I'm still waiting for your arm,leg, irst born, AND/or c #
I have two fine scopes. you can buy this one on your own
SWPadnos: I dont wanna a scope, I want a SA =)
that, you can definitely buy for yourself
In the PHz range!
my arms and legs aren't valuable enough
wait, has usb jack... I'm confused

Goes by yhe ickname 'Lucky'
ok. dinnertime. bbl
SWPadnos, What brand multi meter do u use
PCW sorry to bother you again, but wouldn't the half wave three phase be better than the single phase transformer?
I suppose only slightly...probably not worth the cost of the three phase xfmr.
I like the owon one... anyone have it?

Jymmm, u buy that scope for 900?
I use a HP Agilent 16700A logic analyser with 2 channel scope card. My dispaly is any Xwin system that I can connect to it. Runs Unix
jimbo655, I want a picture of this
and a wright up!
You can see them on ebay..
Geo1005 I dont think so but I'm no expert, DC loads on individual phases has got to be bad
Gamma-X: did you figure out the resistance and wattage that you need for your braking resistor?
What is it?
That is not enough.... What is the control and model number?
3hp motor, and I want it to be able to stop the spindle on a dime
Do you have a spindle brake?
air powered yes.
but not hooked up,
