arrhg! ghost poop everywhere!
accidently knocked over a box of packing peanuts
(the white ones)
heh - oops :)
the "pro-static" kind?
not too bad
that just reminded me of something I saw on one of those "funny video" shows
kitten and a large box of staticy peanuts
I can imagine
the lil' dude was just covered head to tow
new name: snowball
this is so wrong....
I'm using the open office word processor (for the first time) and it looks like the cousin of that thrice damned Microsoft paperclip just popped up in the corner!
yes, but it's easily disabled
seems like it went away by itself
I don't use the word processor anyway
it'll come back - just type hte instead of the
( I just wanted to make a mailing label - its a handy way to get nice big fonts, etc)

2 more windows trimmed
you mean the things we look outside with, or are you programming? ;)
10 more to go. I hate trim.
btw - dyson vaccumes do loose suction. you have to clean the heppa filter atleast once a year.
did I spell that right?
cradek: you don't watch enough tv
they make funky looking vacuums
sorry I don't watch any tv...
honestly - the best vac I have ever used.
oh just a house vacuum - thought it was something cool
Well if you have pets....
well - they work, that's cool
don't they have some insane warranty as well?
no clue - have had it for a few years now. No issues.
I need a new vacuum...
hmmm - I think I know someone who knows the guy who owns Dyson
:) it has a beater bar hand attachment that take cat hair off of funatur. works like a charm
* skunkworks is giggling to himself
I don't know what's wrong with your fingers ... ?
too much vacuuming, I guess
what model do you have?
I think it is time for some wine. And stripping a bunch of ribbon cable.
their handneld looks pretty cool
like a big gun in some FPS game
they're a lot more expensive than a Dirt Devil
(came with the beater bar attachment for cat hair) I don;t know what the current model would be
the DC 07 Animal ;)
Yes - expect to pay around 300-500 dollars
I know - I know.
But I really think it was worth it.
you could probably get a used one on ebay
whoops, too slow
so I suppose there is a really cool ribbon cable stripper out there.
I've never seen one
usually ribbon cable is used with IDC connectors, so youdon't need to strip
interesting. I thought about that today. but to use a protoboard that I have - It doesn't have a place where I could slolder in a header. (2 rows with solder traces) if that makes sense
so I figured I would just fan out the ribbon cable - solder in it one log row
ah - well, get out the tiny wire cutters, cause you're gonna need 'em ;)
I have done it before I guess. I can actually just fan it apart and strip it with my fingernails.
sharp finger nails
hmmm - I wonder if my die crimper can crimp copper tube
probably - how big?
I couldn't find 5/16
(and 1/4 was too small for the wires to fit in)
wow - this stuff is stranded.
of course - that's wh yit's so flexible
I know the high density ide is solid.
the 80-pin ones?
hmmm... it shouldn't be
the 80 pin one I stripped a few weeks ago was.
really small too
came with a hd I am sure. probably a cheap one
you get a cheap one or two with just about every motherboard as well
though newer ones are coming with SATA cables and no IDE (or only one)
I just got to play with a core duo. 2.8ghz. outperforms my hyperthreading one about 2 to 1
not even a core 2 duo
that's not too surprising. is that CPU vs. CPU or clock vs. clock?
ie, is the core duo CPU 2x as fast as your other one, or is it 2x as much speed per GHz?
running a bunch of test including a nortons speed test both where 2.8ghz
ok, so the numbers are the same ;)
you should benchmark something important like the minimum BASE_PERIOD that doesn't make the system hang :-P
I was very surprised at the speed increase when I replaced my Opterons with dual-core models
well it boots with the ubuntu 6.1 edgy 64
you mean 6.10?
sorry - jmk yells at me for that mistake also 6.10
I don't yell
it is "six point ten" - for the release year and month
well your a little short ;)
coworker could not belive that the amd64 version worked on the core duo
Intel licensed the x64 instructions from AMD
really - they call it the EM64T
Intel added some instructions, then licensed the AMD set
and I think they more or less killed off their own, but I'm not positive
they do have a different name though ;)
you mean, killed off itanium?
no, Itanium sitll (barely) exists
and it's actually very fast for some problem sets
not "FPS game" or "net porn", I guess
maybe "embarassingly parallel code written in fortran" or something
I wouldn't know :)
if I have a symlink pointing to some file, and I'd like to replace it with a local copy of the file (so I can edit the copy without messing up the original) is there an easy way to do that?
in this case, I have 12 of them in a directory
remove the symlink then copy, or copy over it?
12 times typing the names and paths... I was hoping for some trick
I guess a for loop
or I could go GUI and use the file manager
that would probably be too painful for you :)
whats painfull is admitting that the GUI way is easier in this case
there's always double-click / middle-click in a terminal
heh, cmd line wins again
the GUI copy gave me links, not copies
for loop to the rescue
you can middle-drag, I think, and it should give you options
jepler: your write up makes sense. you mention you can use the pwm outputs as outputs if they are not used. Is that going to be configureable some how in hal?
even if it isn't, you can always set the PWM to full scale one way or the other, or off, to set the two output bits
hopefully it will be configurable though, that's a kludgey way to do it
one ribbon cable soldered in
man - mouser is dumb
why is that?
they added Digi-Key like filtering (the multi-select list boxes), but their FPGA selection criteria don't include "number of gates"
I like the filtering, but gate count is maybe the most important feature of an FPGA ...
you can't use digikeys filtering - then see if mouser has it? :)
me does that a lot
only for lines they both carry ;)
it looks like Mouser has lattice parts, but not Xilinx
DK the reverse
trying to get something <300 pins or so with ahigh gate count and high speed isn't all that easy
this for the robot project?
I'll probably just buy Mesa stuff for that
aww - thats cheating
well, the idea is to make money on that project, not have fun :)
ok - if I go up to 320-ball FBGA then I can get 1.6M gates for $50 or so. not bad
I don't understand? ;)
I can have some fun after I get the money ')
hmmm - maybe I should have some more pumpkin pie
pumpkin pie. mmmm.
I should go to bed.
freshly made tonoght, even
nice. email it to me.
I'll DCC it ;)

good morning for all people
i need yor help
what do you need help with ?
I have 3 stepers motors
how configuration in file.ini?
how calibration in hal.ini?
help me pless!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
good morning for all people
my name is Rafa
I from Brazil
and i need yor help
ask away. There doesn't seem to be too many people up yet. (my help my be limited)
where you the one yesterday with 2 printerports?
I wasn't any help. that was the gurus helping you.
you can help me
can help me?
did it work?
my sistem work
it has plus an information
that I would like
how calibration my stepper motors?
i have 1 problem
and i need yor help
ask away :D
I have 3 steppers motors
as to calibrate?
Guest348: you can set the units (mm or inch), the number of steps per unit, the maximum speed, and the maximum acceleration in the ".ini file", which you should edit with a text file editor
please one moment
my stepper is work in milimeter ok?
Guest348: ok, what you need to specify is how many steps are in one mm on your machine
in the document http://linuxcnc.org/docs/EMC2_User_Manual.pdf
describes the ini file starting in section 7.3 (PDF page 80)
it of the 5 returns for 1 milimmeter
Guest348: just ask if you need more help other than the document :D
I do not understand
Guest348: how many steps per revolution? You must give the number of steps per millimeter, which is (steps per revolution) * (revolutions per millimeter)
please one momment
it can give an example to me?
Guest348: Start EMC, go into JOG mode, select to jog 1 step at a time, and select a distance (say 100mm) put a measuring tape by your machine and count how many steps to move 100mm
Guest348: In the sample configuration file stepper/stepper_mm.ini it says [AXIS_0] INPUT_SCALE = 200 0
Guest348: this would be appropriate for a system with 200 steps per revolution, 1 revolution per mm
(the second number, 0, is just ignored)
if your motor has 200 steps per revolution but 5 revolutions per mm, then you would write INPUT_SCALE = 1000
because 200 * 5 = 1000
it would like to know
Guest348: you said 5 turns / mm ..
so the motor turns 5 times, and the table moves 1 mm.. right?
if the engine this calibrated correctly
ok, how many steps to turn motor 1 turn?
usual stepper motors have 200 steps / turn (0.8 degree / step)
please 1 moment
Make sure that you check if you have microstepping, if you do you have to adjust for it
it would like know if the motor this calibrated correctly
therefore this very slow
Guest348: once you've made sure the axis goes the desired distance every time, you may then increase the velocity and acceleration, to get faster movement.
In g0 this slow
Guest348: The velocity and acceleration are called [AXIS_#] MAX_VELOCITY, MAX_ACCELERATION, STEPGEN_MAXVEL, STEPGEN_MAXACCEL
please 1 moment ..
for example, MAX_VELOCITY = 100 means that the given axis may move up to 100 mm/second
and MAX_ACCELERATION = 500 means that the given axis may accelerate at 500 mm/second^2
I go to pass my data
I go to pass my data of my archive
you should also set [TRAJ]MAX_VELOCITY and [TRAJ]MAX_ACCELERATION to a value larger than any [AXIS_x]
Use this website if you want to show us your ini file: http://pastebin.ca
people very thanks yor help
I need to leave
come back soon
but I come back in 1 hour
I have to go too
ainad necessary of its aid
please it does not abandon me
Any progress Guest348: ?
hello people, i can back!
Guest736: just ask your question. someone will try to help
I am guest 348
I can back
Please help -me
I have 3 steppers motors
I want calibration
Hi have 3 steppers motors, and i want to calibrate
Guest736: did you follow the steps I gave earlier, to set SCALE, MAX_VELOCITY, etc? This is the way you "tune" stepper motors in emc2.
You must determine the correct SCALE value to get the correct amount of movement. Then, you can slowly increase MAX_VELOCITY and MAX_ACCELERATION as long as the steppers still move reliably.
Guest736: Have you edited your .INI file yet ?
I can pass my archive?
My problem is my engine of the 5 returns for 1 milimeter, and it this slow one
My problem is my engine of the 5 revolvs for 1 milimeter, and it this slow one
I can pass my archive?
To change the number of motor steps that are issued to travel 1 mm, change SCALE.
Then, to allow faster motion, change MAX_VELOCITY.
This is all described in the documentation, chapter 7. http://linuxcnc.org/docs/EMC2_User_Manual.pdf
I go to mostar the configuration axis x
I don't know what you mean by "mostar".
ist possible makes a boton "cicle start" extenal?
is possible to make a external button cicle start?
yes, using halui
Guest697: you need an external button connected to the parport
Guest697: some information here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Halui
I have a buton
Guest697: you need to link it to halui then
1. edit your ini so that halui starts by default ([HAL] HALUI = halui)
2. connect the buton to the halui pin (linkpp parport.0.pin-12-in halui.program.run)
I cant use Halui
Guest697: why not?
no start graphic interface
halui is not a graphic interface
you won't see it running
how use it?
19:15 < alex_joni> 1. edit your ini so that halui starts by default ([HAL]
HALUI = halui)
19:16 < alex_joni> 2. connect the buton to the halui pin (linkpp
give me more a example
Guest697: in your ini file in the [HAL] section you need to add a line "HALUI = halui"
then you open your .hal file (probably standard_pinout.hal) and add this line:
linkpp parport.1.pin-10-in halui.program.run
this will link the pin 10 from the second parport to the halui program run pin
whenever the pin 10 is active, the program run command will be sent
has anyone had a chance to take OpenCAM for a spin yet?
eholmgren: if you spin them
* eholmgren falls over
so, is opencam any good?
Lerneaen_Hydra: I heard it makes you dizzy
and then you fall over
sounds nice :D
I did not obtain
to make what you said
it gave error
message ERROR halui.program.run not found
Guest697: that is correct
halui.program.run doesn't exist in emc2.0.x
you need to wait for emc2.1.x for that to work
how install emc 2.1
Guest697: it is not released yet
2.1 is still in testing phase
its possible install 2.1?
Guest697: it is possible, but not easy
LH: not sure yet
I only have this windows box at work
we go to leave for alone
Guest697: it is described in the wiki.linuxcnc.org
... and what is that Gambas crap all about?
some sort of faux visual basic for linux?
i have gambas in my sistem
eholmgren: sort of. if you are getting dizzy from the SF page, wait to you fire up opencam in gambas :)
Guest697: ask your question.. :)
speak on pvt
speak on private
oui, et vous ?
tout c'est bien
tu veux dire : tout va bien
all is alright
seriously, i try to mount the rtai_serial properly
manually, it's ok
its possible make a buton externa "Cicle start"?
It would like to know if start is possivel to use a external button for cicle start?
je peut parler un peu du "franglais"
I like to talk witt alex_joni
please help -me
please help -me
please help -me
please help -me
please help -me
please help -me
please help -me!!!!!!!!!!!!!!!!!!!!!!!!!
Guest614 : if i can help you
i have 1 problem
we can talk privately?
Hmmm, do you folks think that's a sexual problem? Very private ;)
Lerneaen_Hydra: tjena, hur går det i plugget?
jadå, framåt. har klarat mig hittils
blir intressant att se nu när det kommer både el och mattetenta
:) jag kommer ihåg att det är jobbigast 1:a året
hur många är vi nu?
btw, ^Eugenics, var det du som var chinamill innan?
friends i need yor help
I'n private? ;)
I am in the work
vi är väl iaf 5, ^Eugenics, simon78, Bo^Dick, anonimasu, och mig själv
jag visste inte att anonimasu var svensk
nånstans mitt i Sverige är han
och etla också
Guest614: what do you need help with?
är inte etla finsk?
I need to deliver a machine for the customer
hmm, det är han kanske
Guest614: so what's the issue?
[18:27:21] <Lerneaen_Hydra> http://www.anderswallin.net/
<-- tyckte det såg mer svenskt ut än finskt iaf
Lerneaen_Hydra: Har för mig att han höll till i helsinki
Vem är anders wallin?
I need 1 boton external for cicle start
somebody knows Guest614 ? He is french ?
Guest925: I cant see why you could not configure HAL to get an external "spindle on".
Guest925: not possible with 2.0.5
brasilian if tracert is anything to go by
^Eugenics: he needs a cycle start (e.g. run button)
that is not supported in emc2.0.5
Guest925: sorry I read wrong
there isn't support for cycle start in 2.0.x?
Lerneaen_Hydra: not from halui
Alex, how to do for mounting rtai_serial ?
Didier: 2 ways
err.. 1 way :)
edit module helper to allow loading it
then put the rtai_serial in rtapi.conf.in
and add it to configure.in
Btw, Helle everybody, Ive been away for a while...
I hope You are all well :)
well, i note
Didier: open configure.in
for m in adeos rtai_hal rtai_ksched rtai_fifos rtai_shm rtai_sem rtai_math \
oh, btw ^Eugenics, I found a nice manual mill that I plan to get sometime (13 000 kr new). http://www.blocket.se/vi/9301429.htm?ca=11_s
(the same one that etla has, I plan to bug him when he comes by next time)
nice size and everything for an emc machine
Lerneaen_Hydra: I'll be in skáane next week :P
for saint lucy ;)
be sure to get a "lussekatt"
i'm in the file, seeing the line
alex_joni: i hope you have studied the mastering swedish lessons better this time ;)
oh, valarq is also swedish
Didier: add rtai_serial to the end of the line
* alex_joni starts banning/kicking swedes
they're slowly taking over the channel
resistance is futile
next you need to add a AC_SUBST(MODPATH_rtai_serial)
then you need to run autoconf
configure will be generated
if all is well you won't get an error
btw.. rtai_math rtai_serial\ you need a space before the \
in src/autoconf ?
Lerneaen_Hydra: Verkar som ett hyfsat pris... Men det är långt ifrån kulskruvar
in configure.in, where you wrote rtai_serial\ make sure you have a space between rtai_serial and \
yes it's ok
then exit the editor
where to launch autoconf ?
and write "autoconf"
it's a command
if you don't have it: sudo apt-get install autoconf
^Eugenics: jo, det vet jag. jag hade tänkt mig någon förspäng mässingskruv eller likn.
in the repository src of emc2 ?
i have made it , it's seem ok
går lite trögt men jag har större stegmotorer
ok.. if it's ok you get no message
it's the case
Didier: next run ./configure the way you do it usually
see if it still works
i use ./configure --enable-run-in-place
make is started
Didier: next: edit rtapi.conf.in
Didier: wait with make
Didier: in emc2/scripts/rtapi.conf.in
since of morning I am asking as to make a simple configuration
Guest296: and you are not listening
Guest296: I am sorry if it's a communication issue
we asked how many steps the motor needs to turn one time
rtai_math" becomes rtai_math rtai_serial" line 22
and what about module helper ?
we'll get there
Didier: also MODPATH_rtai_serial=@MODPATH_rtai_serial@
ok, next run src/config.status
run or edit ?
done, no errors
ok, look at scripts/rtapi.conf
Didier: if all went well you'll see the full path to rtai_serial
i have MODPATH rati_serial=/usr/realtime/modules/rtai_serial.ko
it seems good
make now ?
Didier: not yet :)
now we need to edit module_helper
ok, i look for
LH: what language was that, Finnish?
Didier: you can put it at the beginning
i have added "rtai_serial", before "rtai_math"
now make :)
Lerneaen_Hydra: Om möjligt be att få titta på fräsen, så du kan avgöra om det finns tillräckligt med plats för dina modifieringar
(I min sunkiga chinesfräs är det lite för trångt )
make, sudo make setuid, ./emc, lsmod ?
it's ok, rtai_serial is in the lsmod list
thank you very much
no problem.. wasn't that hard.. was it?
when i know it's easy
it's 20h00, i'll eat, thanks again
tomorrow i will try the new configuration
:) :) :)
aw, eugenics left
i want to move configuration of the AXIS
i want to move key R for Key ENTER
i want to move key R for Key F4
there should be bindings in the source, or maybe a config
In the folder /usr/share/axis?
that's beyond my knowledge
or maybe a config?
In the development version of emc2, you can put some lines in ~/.axisrc to modify key bindings. however, this does not apply to emc 2.0.4. In emc 2.0.4, the only way to change key bindings in AXIS is to modify the source code.
using Enter may do unexpected things like mess up MDI mode; be careful
I want no Enter,
I wanr F4
yes, I discourage use of "~/.axisrc" to change key bindings, but many users requested it.
my emc is on Ubuntu
In emc 2.0 (this is probably the version you have), the only way to change the key bindings in AXIS is to modify the source code.
Where this the code in my system
Where this the code in my system?

darn.. think I saw too much welding today :(
my eyes hurt :(
that sucks :/
I feel bad about Guest***
he needs a lot of help, but doesn't understand most of the documentation and advices
or doesn't read it
cradek: I start to think he really has a bad time communicating with us
it's hard to tell but I don't think it's just a language barrier
maybe you're right
maybe he can get some help understanding it locally
we may not be able to help if it's language that is the problem
yeah, I know :(
it might be even worse
language + skills
what exactly was he trying to control with emc?
a mill I think
we don't know
but he said it had one parallel port for X and another for Y
eholmgren: but I don't know exactly
cradek: I don't think so :)
but it might be so.. who knows
well he said that
but yeah, hard to say
might have missed that
I know he was having a hard time today trying to get it to move properly
still had 1.2 max vel for mm
so it was a "bit" slow
wonder why he was worrying about rebinding keys if it wasn't even moving right yet
* cradek shrugs
cradek: from what I understood it was a customer request
oh he's a contractor of some kind?
and he needs to get it done by some date
7-8 days or so
maybe he's missing fingers from a previous attempt :p
ouch, that's a bad time to decide to learn a new system
yeah it sure is
I suggested he gets some help with translations and from someone with linux/coding experience
I can't imagine promising something I don't know how to deliver, then trying to get people to help me do it
I need to control my unknown machine with a nintendo power glove
I think it was his boss who promised
I have six parallel ports
and it needs to be done yesterday
It's what 78% of all software sales people do
promise something that does not exist and expect the developers to work magic to make it :P
Rugludallur: at least they're paid developers
wait - you guys are not paid for emc? WTH
skunkworks: bring out your checkbook
oss isn't usually paid
at least not stuff this scale
Lerneaen_Hydra: shhhh, we charge skunkworks
sorry forgot the ;)
I'm canceling that check then
* Lerneaen_Hydra gasp
now how will I afford shoes for my ... cats?
* Lerneaen_Hydra feels the prickly stare of an uncountable number of devels
* alex_joni kicks Lerneaen_Hydra
covered y shoes ?
actually there's this old covered bridge on ebay I've been wanting to bid on
Rugludallur: covered in gold
it says they'll move it on flat-bed truck to nebraska for only $100
I think I'll put it on my driveway and use it instead of the garage
how much is the bridge?
it doesn't matter, since I don't get paid to develop emc2 I can't afford it
anyway, I'm making this up as I go along
are you sure it isn't the golden gate bridge? I have been bidding on some ocean front property in arazona.
I think I will be able to get you a gold covered bridge
if it's around 10k.. I could get you some woodworkers shipped in a container
they can build you all the covered bridges you want
on that note ...
someone in my area is selling one of those airplane tugs
12,000 lbs and can pull as much apparently
does anyone know where I can find some radiocasette player schematics?
I think sam's photofacts is still around...

there is more than one?

isn't there a major mill vendor that uses EMC in their control system
yes sherline is all emc
they don't toss anything to the developers?
I don't know...
I know they gave us bandwidth for a while
was sherline the ones that were really small and relatively weak (stability-wise)
you'd think it'd be in their best interest
Lerneaen_Hydra: they are small machines but I think they're fairly well designed for the price
cradek: how much are they?
Lerneaen_Hydra: www.sherline.com :-)
yeah, got that.. but it's only a leaflet
oh, they have prices there too
I also have the user manual
the thing I reacted most strongly against was the Z column in the mill
looks very ungaily
ooh, prices weren't bad though
Lerneaen_Hydra: they're not meant to be heavy duty machines...
If I didn't think I'd run into trouble with all the mechanical stuff I'd buy a sherline mill and do a servo retrofit like cradek's done on his sherline lathe. I'd like to have my own machine for circuit-board milling.
I bet cradek would help.
I bet he'd kill me by the time I was done bothering him
just bring out your clone
you do have a clone ... don't you?
jepler: the problem with sherline for pcbs is the table is less than 4" deep
of course, how do you think I've managed to survive
jepler: maxnc is better for that reason
that's only 100mm
Lerneaen_Hydra: my mill can cut 4x6" pcbs, that's about all
that's a standard size I guess
it might have 8" travel in X, not sure
cradek: my version of eagle is limited to 80x100mm anyway
hmm, a bit small
at least for working with metal lumps
you can fix that for $not much
Lerneaen_Hydra: yes it's only for small stuff
Lerneaen_Hydra: I'd like a real knee mill but I don't have one
too small for my taste, I need to be able to cut hardenable steel
I have some machinable steel that hardens nicely
Lerneaen_Hydra: it is small but I've made many useful things with it
can do work in aluminum=
can you work in alumnimun?
I cut steel on it sometimes
cradek: show him your servo moutn.
spicy steel too?

* Lerneaen_Hydra slaps alex with a trout
* alex_joni eats the trout
motor mount and bearing seats
done in the mill?
well some lathe work for the bearings
but the two main pieces were done on that small mill
surface finish leaves a bit to be desired, though it doesn't really matter
yeah it's not very good
is that a limit of the mill or just the endmill/program?
the finish may be better on the scrap - this might be climb milling
oh, I see
I don't remember worrying about the direction
that sounds plausible
is that the piece whose slots are done with the "useful_subroutines.ngc"?
cradek: what where you using for coolant?
yes slots and holes both
hmm, I'll have to call it a day now, early tomorrow
* alex_joni leaves too
jepler: if all that i/o works - you cold have pallet and tool changer on your mill ;)
jepler: on your future mill
and a pick and place robot.
or you could just use it to run your christmas lights.
72 christmas lights is enough for anyone

"Operating at a tape speed of 80 ips, ..."
wow, 2.5 mega...letters per tape
there. weird. always have a problem with freenode
so i finally got my steppers all connected and running emc. not doing anything useful yet, but i can make everything move ;-)
i need to learn rs-274 next i guess
it's easy - learn g0 and g1 and leave the rest until you need it
once you've learned g0, g1, and m2 you can write useful programs
(m2 is the last line of all programs)
g90/g91 are good to use somtimes
i should look over some sample programs
* anonimasu uses them for quick facing and stuff
whatever you do, don't look at cam output
don't look at tort.ngc either
probably like looking at microsoft word output to learn html ;-)
oh also learn g20 or g21 too, but only one of them
cds.ngc might be a good sample, but it's a bit long
heh, not useful-subroutines either
i also will need to design some jigs to hold down the material i want to work on. and make them :-)
making jigs takes more time then making parts really :)
my first tasks will be drilling holes and cutouts in some plastic endplates for enclosures. probably 1/10 inch thick or so
i need a way to accurately position the peices and hold them down
most pieces will be around 1 x 3 inches or 2 x 4 inches in size
somewhere I have db25 gcode cutouts, I should find those and make them public
that's a hard thing :) _around_
that would be great
well, i have two main sizes i will be using
ChrisSmol: that's the kind of thing you're doing?
several things. i want to be able to put DB-9 cutouts on some of the pieces. and a series of holes on some others.
nothing really fancy
DB9 and DB25 would have all the same arcs - would be easy to adapt
How you doing, ChrisSmol?
doing well, i finally got my steppers to work yesterday
cradek: shouldnt be hard to make..
I'm working with a stepper machine right now.
the z axis stopped binding after i loosened the setscrew that is designed to lock it when you don't want it to move ;-)
Ah motion locks. They were common on bridgeports also.
there's so much slop in my big lathe locking is the only way I can face anything
what are you working on rayh?
Stepper version of the Smithy 1240
I'll have a couple of questions about period and such in a few minutes.
I was pretty amazed at how inexpensive reasonable-sized steppers are, compared to servos
(looking at Automation Driect)
rayh: when I search for smithy 1240 on google I see a conversation between us
really. that must have been a while back.
go to smithy.com, it's at the bottom of the products page
rayh, are those maximum torque numbers actually the max, or the continuous for the servos? (22.13 ft-lb)
hmmm - I see it on smithy.com - maybe it's different?
I've not kept up with the new stuff on the web for them at all.
The motors were ElectroCraft(Reliance) 600 watt or so.
about 3/4 hp.
hmmm - I could be seeing the spindle torque - there's a servo torque rating at the bottom of thespecs as well (690 oz-in)
I was curious - I think LH was asking about needed stepper torque for a similarly sized mill, and unfortunately I was the most knowledgeable person around :)
that looks like a nice machine
Spindle motor on the old version was 1 hp
2 hp on the new
ack - $12000 O_O
There are some barebones on ebay right now.
ack ack - $16000 from smithycnc.com ;)
These weigh in at about 1100 lb.
it was hard enough to install the shoptask at my old company - we were lucky to have a nice surplus steel assembly table from IBM or Digital
those are only ~700 pounds
I got as much as 24x12x12 work envelope but we reduced it a bit for release.
"underpromise and overdeliver" ...
something like that.
got a 42 size motor with 1600 oz-in on spec to test.
that's pretty reasonable torque for that frame
running torque comparisons and it ripped the wrench right out of the guys hand.
I should be using a winch and weights.
yeah, or a fish scale
There you go.
Question?? Sort of thinking out loud.
If input_scale is 2005 and max vel is 120 ipm
What is the lowest base_period I can use?
you mean highest (lowest interrupt rate)?
Is that a better way to say that.
the calculation is 2 IPS = 4010 steps/sec, and you need 2 BASE_PERIODS per step, so 8020 interrupts / sec
1/8020 ~= 120 uS or 120000 ns
So that's how that works.
(it's closer to 125 uS, but I rounded down)
Now with the old stepgen or freqgen in EMC(1) I'd multiply that by several times so as to reduce the size of the last speed delta.
alternately, you can look at the "stock" setting of 50 uS, which gives 20000 interrupts or 10000 steps/second. that would give you ~5 IPS or 300 IPM
Do we still need to do such a thing with the new stepgen
yes - that's still a good idea, especially if you're full-stepping
I think it's still a good idea anyway - it may not be necessary
I am 1/10 microstepping.
hmmm - that should be 20k steps/inch then ...
err - 10k
200 steps/rev * 5 revs, unless you're gearing up to the screw
2000 steps/rev * 5 revs/inch
Ah dinner calls, bbl.
