anyone using a pmdx and knows if the ribbon cable for db25 is standard?
danimal_garage: mind if I ask how old you are?
steves_logging ya here? :)
noone knows? :)
frallzor: I don't even know what pmdx is :)
steves_logging makes them if I recall right
its a nice set of break out boards
[00:57:19] <frallzor> http://www.pmdx.com/Images/DB25Ribbon.jpg
does this look like a non standard cable?
the db 25 end looks normal and the other end seems normal
when ordering a I missed the bob itself only carries centronics connector
so I just ordered a http://www.itpaket.se/images/bracket-4.jpg
they seem pretty similar besides the bracket
looks the same to me
PCW_ is now known as PCW
looks normal to me too
hopefully it isnt some odd homemade pinout =)
doesn't look it
goodie, then Im set =)
just make sure you get it all the right way around
pin 1 on the IDC lines up with pin 1 on the plug
if its marked clearly I can check
are you trying to replace an existing cable or make a new one?
trying to get one that works since I didnt get one with it
only centronics on the board
but I want DB25 due to placement
centronics is 50 pin isnt it?
centronics >db25 =)
no idea how many pins
but its only as many as in db25 needed from it
if I use that little connectors I asked about I can place it a bit more freely instead of needing to have the board where the connector have to be
oh well, its late here so GN =)

does anyone here use the Mesa cards in a controller (specifically the 7I43)?
lots of us use mesa stuff - go ahead and ask the real question
oh...where to begin...
I am a novice (in irc as well as machining) so please go easy on my stupid questions
(my machines have 5i20)
I am rebuilding an old EMCO F1 and was looking to use Bob Campbell's Combo Board
I think I know what an EMCO F1 is, but I don't know who Bob Campbell is
But, I want to have limit switches, encoders, a bi-directional
it's a stepper motor machine, right?
Yes, it will be a stepper motor machine (when rebuilt)
in that case, the only encoder you might need is a jog wheel
Will have 23-370 (NEMA motors)
limit switches are always good
was planning to use 102-1308-ND (digi key part number) encoders
I want to have isolation on the limit switches, etc
I saw a web page by user (here) PJM - Paul who uses 3 different Mesa cards to do something similar
The campbell design combo board can drive the motor controller (with an isolated varying DC voltage)
So if I go with the Mesa solution, I need to find a way to accomplish this part of what I am losing from the combo board...
BTW, I am going to use the KB electronics KBPB-125 motor controller for the spindle motor...
I think there is a 7i43 firmware that gives some step/dir outputs and some pwm/dir. but the pwm would not be isolated.
according to the motor controller info (http://www.kbelectronics.com/manuals/kbpb_manual.pdf)
I need an isolated variable voltage of 0-9VDC.
the isolation is just to protect things
easiest way to get variable voltage is just to use the mesa variable voltage card
Oh, which card is that?
no idea lol
a bunch of 1.5V batteries
I believe it gives 4 +-10v outputs from PWM inputs
if you are wanting to do a stepper machine then your best off just using a stepper driver that'll take step+dir inputs
otherwise do a servo system if you want encoders
steppers with an analog input to the driver seems like its mixing a whole bunch of different things with no real benifit
No, the analog (variable voltage) is for the spindle motor control, not the steppers
Sorry if I wasn't clear
The steppers are on X,Y,Z,A and I will use the 7I43 to drive those
The spindle motor is a DC motor
ahh, makes more sense
is it +ve only input that you need?
Not sure what you mean by +ve?
[03:01:40] <WalterN> http://i.imgur.com/1gF1j.jpg
The motor controller info says: All models can be controlled with an isolated analog reference voltage (0-9VDC) in lieu of the main speed potentiometer.
The control output voltage will linearily follow the input voltage.
The source impedance of the input should be 10k ohms or less.
I see the 7I37 board has 8 outputs. Can the voltage be controlled on those?
tome9999: for analog outputs you want the 7I33
but these will not be galvanicaly isolated
the 7i37 is a digital I/O card, so no, you can't control the voltage on the outputs (they're like open or closed switches)
The 7I33 is a servo control board. Should I look for something other then a Mesa board to accomplish this?
Maybe, you only need 1 analog output
the 7i33 provides 4 outputs
but also has encoder inputs if you need that
you could try one of the DigiSpeed devices from http://www.homanndesigns.com/
SWPadnos: WH =)
note though that the digital I/Os on the 7i37 aren't all that fasy
looks like it's off to Dallas next week for the Slam Dunk competition
SWPadnos: whatcha doin there?
um, the Slam Dunk competition ...
SWPadnos: as a player?
yeah, sure ;)
we'll be shooting the dunks
SWPadnos: Not the same system as the grammys is it?
then it's (probably) off to Miami for the Latin Grammys
yes, it is
SWPadnos: same company?
SWPadnos: well, cool. Where in Latin America you going?
SWPadnos: Well, that sucks
SWPadnos: RIO baby, RIO
the really fun part is that I leave Miami on the 19th, which is the same day I'm leaving for Green Bay, so we can pick up relatives so we can go to ... wait for it ... Orlando on vacation
SWPadnos: what do you mean by "pick up"?
so I'll literally walk off the plane in Burlington, say hi to my wife (who will have my boarding pass), and walk right back on the same plane :)
well, we're bringing my sister-in-law and her son with us, and since they've never flown before, we're going to get them in Wisconsin, and we'll all travel down together
They can't walk in a plane by themselves? or jsut the wifey?
they have never had to deal with airports, transfers, Chicago (where they have to change planes), security, luggage restrictions ...
so it's nicer for us to help them out
And the Wifey cant' do this?
she could, but our tickets are on the same reservation
and we're all on the same reservation from Green Bay to Orlando
Every heard the word REFUND?
yeah, ever heard it in the same sentence as an airline?
lol, once or twice.
ah, DaVinci airlines?
they canceled a lot of flights, I hear
Well, I guess you didn't get a REAM ME NOW ticket
it's a pre-reamed ticket
Well, you could just never get off the plane
That would be interesting
it doesn't really matter, I won't be in the same seat anyway
at least it's unlikely
and I won't have any checked bags, so I don't have to leave the secure area
is Log() what this gnome calculator means when it says Ln() ?
ln is natural log, which is less ambiguous than log (which could be baase e or base 10)
yah makes sense ( after i tried a few examples )
the PIC pwm calcs for duty cycle vary with frequency, there's fewer choices at higher freq and more with lower freq. the number of choices is calculated by using LogN() to determine how many bits of rez. thx.
are you using actual pulse width, or doing averaging?
hey Guys, can I disable the home button after I homes the machine? I keep finding myself pressing the home axis button instead of teh touch off button
Or... can I tell axis to ask me 'Are you sure...... bla bla already homed' ?
SWPadnos: actual width ( calculated, havent scoped) , its easier than i thought
* Jymmm is back!
ether way is easy enough, but you get easier filtering with the higher frequency averaging-only mode
and it's slightly easier in the calculation department as well
SWPadnos: Can I bug you?
you already do
Well, i meant more than usual
oh. well not for too long, I'm heading to bed soon
SWPadnos: averaging mode? for PIC PWM? filtering? I want crisp square waves to trigger sparks. i think we're on different ideas
have a good nights rest :)
you want a spark of a certain duration
i wish i could get the pwm to be triggerable each time (that'd be 'iso-energetic), wait for the spark to occur, THEN begin the on time, rather than... i hope the current flows as soon as i turn on the pulse( but that wouldnt be pwm, it'd be triggered pulses )
Is PJM there?
I found your web page with info on the Mesa 7I43 and a couple other cards and had some questions for you
ok fire away
i am not in any way an expert
well, i see you have using three of their cards, so that makes you an expert ;-)
I am rebuilding an old Emco F1 mill with steppers with encoders, limit switches, etc.
It has a DC spindle motor that I am going to control from a KB Electronics KBPB-125
I guess my specific questions are: The 7I43 does not provide isolation, is that correct?
as in isolated I/O pins?
you need the additional daughter board for that
it has something like 16 opto isolated inputs, and 8 isolated outputs
Is that the purpose of the 7I37TA?
If so, what is the purpose of the 7I42 that you use?
yes that right re 7i37
the 7i42 is for the logic level stuff, so TTL drives out to stepper drive boards, I/O from encoder pendant, etc
There are additional buttons etc that also hook up to that card, as well as the limit switches etc
Why couldn't this be connected to the 7143?
well you could solder the wires directly to the IO pins of the 7i43 board
but for the sake of 20-30 $ u get a nice terminal block IO card with io protection
or at least it was cheap enough to not be worth home brewing an IO card
Sorry, I mean why not connect the limit switches through the 7I37 (then to the 7I43)?
well you could do that too
if they need to be isolated for whatever reason
It just seemed like the 7I42 was not needed, assuming you had enough I/O available on the ..37
I was trying to understand why you had both
'future expansion' ;-)
i didnt want to order the bare minimum etc then find i needed another card
so thought i may as well order what i might need
you could probably stuff everything onto the 7i42
the IO protection is worth having in my opinion
just to save the fgpa from seeing nasty transients etc
serious fpga are expensive
I also need something to provide isolate variable voltage (0-9VDC) to my KBPB motor controller
caps and diodes and even TVS/MOV things arent
Understood re fpga
tome9999 is there any other methods of driving your motor controller other than variable voltage?
no, the KBPB (which I already have) does that.
Someone last night mentioned the DC-03 DigiSpeed GX V3
looks like it will work, but I wondered if there was a Mesa solution
not that I am married to mesa or anything ;-)
well in the 7i43 you could use a pwm generator for a start
Yes, that will provide the signal from EMC
then a R/C filter and an op-amp to give you your 0 to 9v
should be pretty simple
Hmm, didn't think about that.
But I will want isolation on that too, so it may have to be a little more then that...
ok weoo u can isolate it at the logic state out of the mesa card
with an optoisolator in the PWM line
or i guess in fact you could use the 7i37 isolated output, connect isolated transistor output to +12v or so, R/C filter and potted down to 9v
Yes, if I am using the 7I37, I might as well use it!
Cool, thanks for the info and advice!
As I get more details I may have some more specific questions on getting the 7I43, etc working
As you say it is a bit daunting at first...
yeah i came from parport step gen so moving to the 7i43 needed a new mindset
but once it clicks into place its actually a piece of cake
and the overall performance improvement is brilliant
you should also add a spindle encoder of good resolution, since the 7i43 has a fast counter clock
Yes, I was going to do a spindle encoder
and its nice to have on-screen spindle speed that u can tie into a pid loop with commanded speed etc
I need to figure out where I can put it on my spindle, may be a challange
in that case u can just rip my configs and they'll work
I also want it to control tapping
perfect, that is exactly what i use it for on my mill
do you mention which encoder you use (on your web page)?
got to run to take kids to school, back in a while. Thanks again for your help!
heh - http://www.youtube.com/watch?v=Umf4dDzK7fI
very anti-cnc... You can do it just as good with a manual lathe and cnc is way to expensive. (he rants a bit)
even for one thread I have thrown a collet in a cnc
the surface speeds just mean the threads come out that much nicer
I have done enough manual threading to lothe it.
manual threading is annoying at best
I think he can't get proper thread shape with that back rake
threading tool should be flat on top
our main lathe - Monarch - makes it pretty easy.. but still. (depth stops and shutoffs)
heh, he rants that the cnc guy doesn't check his thread, but then his idea of a check is to see if a nut goes on it
I thought it was entertaining.
I watched a bit of the cutting but not much of the talking :-)
Guys, can i change the location of the home axis button in EMC? I find it to close to teh touch off button...
ries: the keyboard shortcut for touch off is "End"
that's too close to "Home" ;)
cradek: But.... I still need to have it moved of possible, I work with somebody that uses a mouse a lot....
sometimes we press the wrong button and we need to re-home..
you would need to mess with AXIS source to do that
a other solution would be to have a question box 'Already homed foo bar, are you sure?'
yeah there's not an easy way to move controls around on the AXIS screens, but you can do it by changing the program
SWPadnos: is the axis source in python?
python and tcl
I can add that code and provide a patch.... just need your opinion on it....
adding a (preferably optional) message that the machine is already homed may be good
moving the button around is a fool's game - there will never be 100% agreement on where it should be
I can promise to look at and consider the change, but I'm kind of afraid of where you will end up when you try to change the program to suit people who can't click the button they intend to click
cradek: it just happens once a while in the act of working, and for some older people (in this case) they might press the wrong button
is it harmful to rehome in your situation? On my machines it takes a few seconds but otherwise doesn't matter
I suppose if you aren't homing to index you'll possibly get a different position
The big problem is that when the 0 is moved, you have the potential to crash against the edges... now I could add limit switches, but still, when a gantry rushes fast into one or the other direction and you bring it to stop fast due to limiting switches, you still of a bad solution
if that's a concern when homing, your homing setup is defective
why is that?
yeah I'm struggling to fully understand the actual problem here
the explicit function of homing is to align the physical machine zero with the logical machine zero
and I tell exis how big my machine, right? (1220x2440 mm)
then I can jog up/down correctly and Axis will know what the limits are
I cannot crash it..
ries: sounds like you dont have home switches?
and the homing procedure shouldn't be configured to crash either, since you theoretically don't know where the machine is until it's homed
danimal_garage: correct, but let me go on...
oh. if you have no real homing hardware, then homing is relatively useless
or you need to manually move to some marks or something
if I home where the machine is at X 1000mm, and I move the gantry up then I crash at the end (potentially) because Axis thinks that I was at 0 physically.
I don't have homing hardware, not limited switches.. I move the gantry by jogging it to 0,0,0
yes, you are using homing in a way that makes accidental homing a bad thing. I don't know how to fix that without adding home switches
understood. I see the problem, and suggest getting home switches :)
The problem with limit switches in 'our' case is that the gantry is like 100 or more pounds, adn can move at 2500mm/second that you don't bring to a hald quickly enough with limit switches
SWPadnos: accidental homing sucks in my position too. My home switches arent accurate enough to trust them, so i gotta re indicate the fixture
all the more reason to have homing that's hard to screw up
use a roller-lever type with a relatively long cam
i have steppers
SWPadnos: cradek where should I have these switches? at the end or like 20cm before the ends?
you can put it somewhere far enough from the end so there's no damage
a home switch can be anywhere, but if it's near one end you don't need such a long cam
like I said, I cannot bring my gantry to a hold quickly, like metal milling machines can do..
you can also home at a slower speed
so I need to have some deacceleration time
limit switches should be placed to allow you to stop before hitting the end of travel
did you really mean 2.5 meters/second?
SWPadnos: it can do it yes, I rarely do... but during fast movements (G0) over a large piece of MDF, I don't see a reason why I should move fast...
and the total travel is 1220x2440mm
SWPadnos: it top speed yes, 2.5meters/second is possible
wow, that's fast
some machines disconnect the amps and short the servo (perhaps through a resistor) with a contactor to do active braking
maybe you could hardwire your limit switches to do this
seems like one crash at that speed because of incorrect homing (or any other problem) could destroy your machine
cradek: it's scary to see how fast teh machine can go...
Liek I said, I ususally don't jog that fast
But the gantry + router is around 100pounds
it's a machine like this : http://www.youtube.com/watch?v=EwO_KL1GRww
I agree I should have limiting switches and a proper homing sequence, but to make this reliable I am not sure how to do that yet
However it sounds like I need two switches on my X and Y axis (I can stop Z fast enough)
cradek: did u get my message yesterday?
one to detect 'near' edge, and one to detect 'at edge'
limit and home switches, huh
danimal_garage: yeah, thanks for sending the stuff
at edge I will use during my homing, and near edge I will use to slow down the machine when I am reaching the end... does that make sense?
danimal_garage: didn't you get an email from paypal?
ries, if you place the limit switch far enough from the end-of-travel that it can stop (from the speed you're homing it at) then you could do a double-bounce homing sequence, and only need one switch.
(not that I know if that's really a thing, but it seems like it would work)
sure you can home to a limit switch (but of course not if the limit switch is hardwired to disable motion)
so 'home' once fast, stop when it hits the limit switch, then back up a bit and re-home, slowly.
bill2or3: emc does this two-speed thing for you
you'd have to be using a switch that the axis wont destroy if it hits it at speed, optointerrupters I gues.
cradek, ahh, cool, I didn't know that.
* bill2or3 hasn't actually connected his limit switches to anything yet.
bill2or3: it can home all sorts of ways (including with no home switch)
cradek: I was planning to feed the limit switch back into EMC so it can properly decelerate, not like a estop system
cradek: opps! thought that was payment from someone else. Thanks!
danimal_garage: thanks to you too
ries: if emc senses a limit switch hit, it stops immediately and disables the amps
cradek: That would be dangerous for me...
but, during homign I mean
29lbs for that stuff lol
I trust emc good enough to not fail in that, just that I need a way to not re-home once the machine is up and running..
I do have limit switches already (opto doesn't work reliable with wood...) so may be I should read and fool around with that....
now that we have unhome, we could actually forbid/ignore homing an already-homed joint. that would be a big change becaus this has never been an error before.
is there a way to put a button in pyvcp so that you have to hit 2 buttons in order to home it? might eliminate accidental homing.
danimal_garage: well you can't disable the normal AXIS homing button anyway
re: home button, maybe dont change the location, but change it to a large border (make the button smaller and ths further from its neighbor) ( pad in axi\s.tcl) ?
that way lies madness, IMO
anyone with c++ experience around? If I have classA.h which needs the definition of classB, then at the top of classA.h I put #include "classB.h" BUT inside classB.h I need classA to be defined so I try #include "classA.h", and that results in circular reasoning which makes the compiler unhappy.
in some cases we already don't have enough room on that screen...
how about a drop down menu that has the axises on it, so it isnt a button anymore. kinda like the select jog incrament box
i guess not so easy for non-mouse users though
homing (and unhoming) are already on the Machine menu. I suppose someone could just remove the Home button (on his own copy)
that'd be smaller ;)
i was thinking a home undo button in the machine menu would be a life saver
so it goes back to the coordinates before the last home
I was just thinking about a dialog that pops up with a 'are you sure' question, YES or NO buttons. That would not clutter the interface and it's also easy to use for touch screen users...
The popup only appears when it was already homed...
i'd say moving it to somewhere else would be a better idea
usually you just want to home once.... I am a newbie so, don't take my word for granted...
ries the touchy interface is pretty nice
pretty well optimized for touch
I think I like that idea the best so far (are-you-sure dialog if already homed)
yea that is a good one
frallzor: I know you worked with that.... Not saying that axis should be a new touchy, just that a popup is out of the way always no buttons, no menu entries) but only warns you when you want to re-home.
is it that easy to rehome? never done that
frallzor: yes it is... you need to un-home first, then re-home again...
cradek: i tried to find that tool touch off, and all i see is g54 through g59.3
but sometimes when I want to touch, I have teh position for my touch.. and after a re-home I need to find that position again. The whole procedure takes about 1.5 minutes (best guess)
danimal_garage: load a tool
if you're running 2.3 or 2.4 and a tool is loaded, you should get "T" on your touchoff options
i have 2.3.4
and there is no t
i'm doing t#m6 in midi, followed by g43h#
is there something i'm not doing?
[17:16:46] <cradek> http://timeguy.com/cradek-files/emc/tool-touchoff.png
mine doesnt have that
haha i'm a dumbass
start emc, F1, F2, control-home, f5, t1m6, f3, z, touch off
has to be in z
I should have thought of it
me too lol
well i found it on the lathe at least
mill is still apart
on that note, i gotta run. gotta finish this thing so i can get some parts out
lemme know if you have any issues with the stuff, i can exchange them if they dont work
but mine worked fine, so i expect yours should be the same
is 8mb of ram enough for a video card for emc?
that sounds very little for anything at all
easy to try
yes it is
were not doing hardcore 3d apps here
tom3p: i'd have to buy it to try it
opengl visualization dosent require video memory?
dont buy it, look for better
i'm looking for the cheapest that'll work
this one is $14.00
I'd suggest buying the best card you can for as cheap you can
yea i'm not doing that
what sort of oGL simulations are you doing
mine has 8m ram i just checked and never had an issue
are you running axis as ui?
the TCL app *prolly* isnt hardware accelerated anyway
its written in python
get a cheap card, as long as it supports the resolutions you like
i run 1152xWhatever
* anonimasu sighs
6$ more for 332meg
That's a cheeseburger
lol, CNC on a budget eh?
will you build your own stepper drives too?
my computer has this big board that has vga, ethernet, and the ide drive ports on it
i'm trying to ditch it to save sapce
i need a vga card for that though, and it needs to be pci
i have a box full of great agp cards, but no agp slot here
might grab an atom as well
for the lathe
the pci matrox are getting rare
[18:48:25] <danimal_garage> http://www.newegg.com/Product/Product.aspx?Item=N82E16856119011
danimal_garage, two points about that (nice little) PC: 1) it's an atom 230, which is the single core version - I don't know what experiences people have had, 2) the slot is low profile, so you wouldn't be able to use e.g. a Mesa card in it, and your video card options would be limited (as well as any other I/O, like parallel port cards) It also doesn't have a parallel port
i was gunna ditch the enclosure and mount the whole thing in my machine's enclosure
and i dont see a need for a parport
oh. in that case you might as well just get the D945GCLF2, it's $80 I think
oh ok cool
only if you can't fit a mesa card in the machine ;)
or if i want to use my dot matrix printer someday lol
[19:01:05] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16813121359
i tihnk thats the one i was looking at when i was at the store yesterday
i guess the only reason i didnt get it was because i'd have to buy a power supply and ram
i did find the 32mb vid card locally for $15 though
oh right. that would be an advantage of the all-in-one unit
though you still have to buy RAM, that doesn't come with it
i need a slow powerfull spindle, has anyone an idea? if possible with toolchanger
SWPadnos: yea, ram is the bummer
if it used ddr, i'd be all set
2GB of DDR2 is $43 or so
i dont think i have any ddr2
add in a small SSD drive, and you're still under $250
$43 is alot of cheeseburgers
(with a power supply)
well, go on a diet
this is computer hardware!
i have a few hd's
the advantage of the all-in-one (other than the power supply) is that it looks like it's fanless
except for the power supply
Guest721 is now known as skunkworks_
dammit i need a more compact 24v power supply
my PMDX has integrated 24V supply
its very small
should be able to find that kind cheap
its a bob
break out board
it has a nice little 120/230V>24V transformer on it
i just need it for relays
i guess i can get 12v relays, but they're like $9 each, and i need 4
is there a way to make AXIS not load the emc2 logo by default?
there are at least 3 ways
good! I haven't found how yet looking at the docs
an environment variable (don't remember the name), an ini setting (don't remember the name), or changing axis :)
there's a line in ini that says introductory graphic
the file name is there. you can change it.
ok - AXIS_OPEN_FILE environment variable, [DISPLAY]OPEN_FILE, or you can put it on the command line
that's not the same thing
that's the Tux image that pops up before your GUI
i thought thats what he ment
so the OPEN_FILE setting goes in the display section?
ignore me then
no, I'm talking about the emc2 gcode shown in the backplot.
It breaks bits!
hey mozmck, how far from Dallas are you?
yea i'd like to get rid of that too. it sucks when you have a lathe, and there's no y axis so it gives you an error all the time
'bout 50 minutes north.
danimal_garage, AXIS will load a different file for lathes, if you have LATHE=1 in your ini
SWPadnos: want to come out? or meet somewhere?
oh i guess i dont have that in my ini
well, I may have some time off in Dallas next week, like Wednesday afternoon through Friday morning
danimal_garage, you should put it in for your lathe
it changes a couple of things about the backplot, and probably other stuff I don't know
mozmck, I'll have a car, so I can come out there. It would be interesting to meet Tom (we may have met before), and see the shop
Yeah, that would be neat!
i was wondering why the interface was weird
I don't really know how much soldering / network testing I'll need to do, but in theory I'll have time off :)
SWPadnos: do you ever come out to san diego?
:) that would be great if you have time.
never been there, though I'm in LA (with no spare time) fairly often these days
la is a bit far anyways. about 120 miles or so
not too bad if I have time
you could check out the shop, and maybe convince yourself to build your lathe once you see one in action
not that my build is something to write home about
I'm convinced, just busy :)
although i tihnk i actually did write home about it once in my christmas card to my parents
yea i hear ya
but with the amount of guys on here with the same lathe, you wont have to do much "exploratory surgery"
so it should go fast
so to prevent any file from loading you would just say OPEN_FILE=
what lathe is it? I need to find one!
it's a little guy
mozmck_work, if that doesn't work, make a tiny file that says G20 / M2 and load that
[19:48:10] <danimal_garage> http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/
ok, I'll try it. can't afford too many more broken bits (only one so far...)
perfect size for a garage operation IMO
ok off to get lunch, adios
looks like. my shop is 26x30, and I have a 12x20 room inside, and 4 manual metal lathes, table saw, CNC router table, 6000lb mill, drum sander, 2 wood planers, jointer, and etc.
I need to get rid of some stuff...
i'm about as bad off as you
i got a little 2 car garage with a 6000+lb mill, bridgeport manual mill, harig surface grinder, 14x42 manual lathe, 80 gallon compressor, hardinge hnc manual lathe, washer, dryer, anodizing setup, workbenches, a few roll aways, welder, sanders, buffers, bandsaws, etc
all the wood working stuff is outside under my patio (stays pretty dry out here)
hardinge hnc CNC lathe*
thats kinda insane
you can anodize? do you do contract work?
oh, I see.
yeah, sounds about like my shop. I forgot my 2 bandsaw, shelving, welder, 55 gallon dust collector, etc :)
wha! the pickit2 programmer is also a 3 channel digital scope on linux http://sourceforge.net/projects/pk2-la/
neat! I have one, I'll have to try it.
it's a digital input "logic analyzer", not a scope
3 bits in, digital only
oh, It does that on windows too. haven't used it for that yet...
jackc: i anodize my products, my setup is kinda proprietary to that. dont do much contract work
dont mind helping people out though
Danimal-office: soooo if i were to cut an occaisonal part for my bike or something, would you be open to me sending it to you with some cash for anodizing or no?
no problem if you dont want the hassle, just wondering
dont want any money, but i can help ya out on occasions
heh certainly your time is worth something. do you make parts for a living?
everybody's time is worth something on this channel, but everyone helps anyways. Just pay it forward.
i cant help many people with emc just yet so anodizing is about all i can offer lol
i make bicycle parts for a living
oh thats quite cool
for a company, or do you design them too?
single speed mountain bike parts
i do everything myself
do you have a site?
[20:52:30] <Danimal-office> http://homebrewedcomponents.wordpress.com/product-pictures-and-pricing/
just a blog so far, working on a site
Danimal-office: what do you use for CAD and CAM?
hm i use solidworks, havent heard of mcamx. you got it to export in a manner EMC is happy with?
ah heard of it then, sorry
in the Big Shop ive used solidworks to Esprit (which is really cool for curves and 3d surfaces) but I could never get EMC to like it
mastercam works great with emc
although my stuff is all 2d
anodizing is easy if you wanted to do your own setup
just some battery acid and a power supply
i used a computer power supply when i started
id love to do it myself
how do the colors work?
* jackc googles
the anodizing process opens up pores in the surface of the aluminum, and the dye soaks in. then you seal it and it's permanent
hold on, i'll link ya to a good site for learning
[21:04:55] <Danimal-office> http://www.caswellplating.com/
over on the left, there's a link to the forum
that site is where i get all my stuff
the forum is good for learning/asking questions
* frallzor is bored
* danimal_garage thinks of Van Halen everytime Valen pops in
[21:28:12] <Valen> http://en.wikipedia.org/wiki/Valen
i think you were better off with Eddie Van Halen
is halscope a scope or a "logic analyzer"?
halscope doesn't really have limitations that make it one or the other
if it measures analog values and graphs them it would be a scope I think.
scopes have a limited number of channels, and often no pretriggering; logic analyzers can't display analog signals
so it's neither and/or both
i wanna tshirt that sez "neither and/or both"
wow that internet is somethin
To satisfy my curiosity, and not for any other reason because it is only a play-config, does anyone know what the joint.N.position-fb Output pin is for?
I wonder if that's in the current coordinate system or something
vs. offset machine coordinates (offset by home offsets or something)
are the homing sequence in EMC defineable or are they like an absolute coordinate version of g0 x0 y0 z0 ?
Sounds about right. http://linuxcnc.org/docs/html/config_emc2hal.html
is a little unclear what one is expected to do about it.
ds3, homing is covered ad nauseum in the manual
ds3: Definable. You put a sequence number in the INI file and it homes all the 0s first, then the 1s etc
and the manual is accurate/current?
probably (more or less :) )
Though that reminds me of a question, are the [AXIS_1] tags freely exchangeable for [JOINT_1] ?
turns out the home switches for my machine are located such that it will crash if the wrong sequence is not followed :(
anyone doing something interesting with a nice machine? :)
you have to follow the wrong sequence?
if it is random, "wrong" is bound to happen
No, I am doing something interesting with a horrod bit of Chinese iron.
designers put a duct in that will cause a collision
also an import machine
[22:34:53] <andypugh> http://linuxcnc.org/docs/2.2/html/config_ini_homing.html#HOME%20SEQUENCE
I'm just planning out things... I expect to be buried neck deep in the docs this weekend
I ought so start the project I bought the machine for in the first place, now it is fully working. What I actually want to do is buy a proper 1950s Mill and Lathe, and convert them to CNC knowing what I know now, and hoping to learn the rest.
why not start with an old/ancient CNC instead? i.e. a punch tape machine
They cost money. And besides, I reckon basic machine tool design as far a the metal is concerned peaked in the 50/60s
andypugh, a horizontal mill available at the right price but its in south derbeyshire
Is it rather tiny?
[22:40:23] <archivist> http://www.archivist.info/cnc/works2008/P1010201.JPG
andypugh: i cant see buying an early 80's/late 70's cnc costing as much as trying to retrofit a manual machine
no not tiny
ball screws and all that stuff are $$$$$$$$
the local JC was saying they wanted to sell off an old hardinge clone CNC machine "at a favorable price" a few years ago... prehaps other places are doing the same?
You are probably right. And the sensible choice would be a Denford Orac. except I would really want to keep that totally stock as a museum piece.
i bet a decent manual machine would cost quite a bit more than a cnc machine with a bad control
andypugh: you have an Orac you are working on?
andypugh, the difficult bit it that mill has to be out by monday
No, I have never even seen one, but they were made in my home town. Only otherwise famous for a brass band and Wilf Lunn.
Archivist: You have any details, my dad is an accidental collector of old machine toolsand has a lot more space than me (and is in Yorkshire)
I have the oracs baby brother the starturn
andypugh, then we have more than one available
Swap for a 19" Ormerod Shaper?
my hometown is known for the birthplace of ESPN
andypugh, that one is a Adcock and Shipley, we also have a rare turn of the century vertical mill Garvin
Hmm, my dad, as an ex gearbox designer could probably enjoy making a vertical head for that Adcock.
andypugh, garvin http://www.collection.archivist.info/searchv12.php?errlev=0&srcdata=title&srcprog=searchv12.php&searchv4page=1&searchstr=skeleton+base
[22:56:21] <alex_joni> http://eneas.juve.ro/~juve/SpcaPict%20(1).jpg
* alex_joni is happy :D
what is that?
danimal_garage: a really crappy photo
taken with a webcam, on openwrt running on my router
so its running?
I just spent 6h backporting and compiling the driver and application for it
yup.. it's pretty dark here, so I placed a led strip infront of the cam
you got usb working on a wrt?
bill2or3: usb is pretty easy (asus wl-520gU)
it's this damn spca5xx that caused me pain
not sure what all that means, but sounds cool so congrats!
danimal_garage: haha, thanks ;)
compiling emc2 (heck even rcslib & emc1) is way easier & faster
i gotta figure out how to move a 6000+lb machine a few inches
no way to get under it
danimal_garage: you need a bit of force..
small mass * big velocity
or big mass * small velocity
do you have a fixed point which you could use as leverage?
[23:02:54] <jt-plasma> http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/hardinge04.jpg
a wall maybe?
jt-plasma: no way to get under it
alex_joni: no wall that'll handle this
danimal_garage: I often use a device (not sure how that's called)
it's made out of 2 screws + center piece
the 2 screws have opposite thread directions
any fork openings?
when you rotate the center piece the 2 screws get pushed outwards
little notch in the front center, enough to get a prybar under, but not a whole lot a prybar can do with this.
danimal_garage: two people with prybars could lift my machine about that size
cradek: pretty much
cobble up a toe jack with a bottle jack and some steel bits
although a lot bigger, and it's not meant for pulling, but for pushing
yeah that's easy for a bottle jack
about 1" screws
I've been pushing 10.000lbs easily with that
jt-plasma: tried that with some 1 inch round stock
holy crap, i got this thing off the ground in the front, and a 6 foot pry bar still wont budge it
guess i need to eat some weaties
* jt-plasma takes the bits out of the new to the Hardinge computer
danimal_garage: you need to make sure it touches ground in as little places as possible
get your computer placement figured out jt-plasma?
woo got it to move 1/4"
see, only a couple more
needs to move about 3 inches sideways
danimal_garage: mind if I ask how old you are?
w00t got it!
now i gotta move my bridgeport
but thats easy, i can move that by hand
whee.. someone younger than me in here :P
* WalterN is 22 :P
johnson bar http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200326481_200326481
oh dang... next month is my birthday :(
using a johnson rod sounds painful
I just discovered $447 in one of the bank accounts I abandon when I moved here
then put these under it, and jack the machine onto real pads http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200342863_200342863
WalterN: thats a happy birthday
thats just enough for a blendtec blender :D
except that its two states away
wait no 26 for a while at least
they have this thing called the internet these days i hear
they say you can do banking on it
there is this thing called a pin number that they evidently gave me when I made the account
not sure where I left all those papers
yay for pickled garlic :D
* frallzor wants his housing so he can put most of this http://pici.se/p/JXUsjynip/
in it =(
got your pmdx breakout?
off to bed for me.. have fun guys
Just build a case, chaps. A bit of Bosch extrusion and some MDF painted black makes a decent case, and then when you want some more room it takes 30 mins to expand it.
* alex_joni built his last enclosure..
took a lot of time though
I've ordered a proper one =)
[23:48:38] <andypugh> http://picasaweb.google.com/bodgesoc/Gibbs#5398215381172597314
nice little polyester one reinforced with glassfibre
First-time build took a couple of hours, but mods to expand a lot less
That's 1U of server, 2U of drivers and interface and 2U of VFD
going to wallmount so I wouldnt trust a diy case =)
I would trust that case to break the wall.
Thats 20mm x 20mm extruded aluminium section as the frame. You could park a (small) car on it.
not the best type of walls in the garage so I need as light as possible too
see if you have any local electical surplus yards
look for some nice hoffman enclosures
we are using a surplus cupbord
i scored a few for about $20 each
we tried to fit ours into one that sort of size
didn't work lol
