yes thats bezier SVG but you gotta carve a path thru those points, lotsa points in between
i wish to check a job cutting simulation and i dont have a third axis Z installed in my machine
did you know any trick to disable the third axis?
because i tried setting the home search and latch to 0 and it still searches for the z axis to be homed
anyone here use stepper motors with parallel port?
still having issues, huh
kinda, 28 ipm is kinda low
what kind of microstepping do you have?
I'm not sure what my bottleneck is or my issue is
well I was 16x, but I changed it to 4x and I can go faster
4 times faster?
16 microstepping and 4 microstepping
yea i know, how much faster is it now that you have it at 4x??
whats your latency and step length?
latency is 10k I believe
how about step length?
1000 I believe
thats not bad
sec I'll boot the machine and check
did you try to change the max velocity in ini?
ya and that helped some I believe
What resolution does 4x stepping give you?
what's your base period?
ok now I'm getting 1.4in/s velocity
well thats not bad
think 0.00025 is a good resolution?
going from 16 microstepping down to 4 made a big difference
i currently have my maching set at 16m and think going to 8
it stalls at 1.4 velocity
try adjusting your acceleration
lower or high?
what are you at now?
are your steppers small?
for the machine?
i dunno, i would think 5 is slow enough
but maybe try 4
the place I got them stopped carrying them.. probably because they are poop
How big is the machine? What kind of screws
[01:49:18] <tlab_> http://www.probotix.com/FireBall_v90_cnc_router_kit/
this is my stepper http://dl.dropbox.com/u/3706935/HT23-200-6_specs.jpg
What drives? And what is the drive voltage?
[01:53:48] <tlab_> http://www.allegromicro.com/en/Products/Part_Numbers/3979/
that's the driver
Hey guys, any idea for disabling the third (Z) axis?
i mean disable in emc 2 as i have a 2 axis machine
and all the jobs require a Zaxis
you want to disable the z axis, but require a z axis
i just want to make a cut simulation
and have only 2 axis in the machine
and emc is calling for a Zaxis
whe i try to run the job it says joint 2 following error
its a servo/encoder machine
one more info
if you don't have a Z axis, you need to either fake (loop back) Z, or take Z out of your gcode
the machine has the Z axis only on of (up/down) comanded by a airpressure valve
of course you get following error
how to loopback Z?
smth in hal?with net command encoder in to encoder out or what?
im not getting it clear
tlab, seems like you should be able to move pretty quick. You might be limited by acceleration over these short distances.
erjos: sim configurations have position loopbacks for this reason - have a look at how they do it
tlab, when you said .0025" resolution was that in 4X or 16x steps?
.00025 at 4x
Quarter Step 0.00025"
Sixteenth Step 0.0000625"
I'm wanting to route pcb boards
tlab, you can't proove that .0000625 exists on that machine. stick with 4x
I just moved it to 16x to see if it would move smoother because when it moves sometimes it sounds jerky
when I jog it at a low speed it sounds like poop
is everything free and smooth mechanically?
I believe so, but I'll double check it
is it normal for one axis to be able to travel quicker than the other?
thanx cradek,im searching but still nothing
You might be getting cogging. I'm not real familiar with steppers. Honestly its been years
tlab, depending on screws and machine setup. ie weight and screw pitch
screw pitch is the same for x and y but weight is different
tlab, even is the machine could do 100IPM, you are limited by the ability to get up to that speed. It takes time and distance to reach a set velocity
tlab, then one can be set to acclerate faster than the other
so since I'm doing small pcb boards, I'll have to stick with lower velocities?
I can't say for sure that is what is limiting you, but it could be.
should I try lower velocity and faster acc?
tlab_, are you back?
I tightened some bolts the other day and I think it may have put it in a little bit of a bind
I'll have to pull the steppers and check
I should be able to turn the screws with my fingers, but how easy should it be? like really smooth? or just be able to turn them?
Not sure on those motors. might be a cogging present. but if there is binding, you'll get noise
I'm not up on tuning steppers, but sounds like you have the acceleration to high.
i have some binding on mine. i get a bit of a wobble at the same point in screw rotation
and I just have brass couplers
tlab, how many IPM are you getting now?
and it works okay?
how low of an acc should I go?
You have to find out 'how fast can high can you go'
ya pretty much... I hear some unwanted noise every now and then
Isn't there a procedure in the manual
ya but I'll test it and then when it goes to run it will still stall sometimes
stall. as in just stop?
ya it stops, and I hear a grind
That sounds mechanical. But what about your supply voltage, is it staying stable?
I dunno I'd have to measure it
Does it stall in cuts? Or when more than one axis is moving?
What is the output amps of the supply?
the ps will do 32V 10A
but is it
last time I checked a stepper motor pulled about 0.8A sitting and around 20mA running
i ended up using a spare 20 amp supply from one of my ham radio rigs
tlab, did you link me to the right motor?
The sheet says 1.5A per phase.
[02:54:48] <tlab> http://dl.dropbox.com/u/3706935/HT23-200-6_specs.jpg
it a unipolar hooked up as bipolar
I'm confused, 20mA isn't enough to do anything.
well the DC supply has a amp meter on it and that's what it said, but maybe it's off
Is the 1.5A rating for uni or bi?
probably calibrated for the max value
all I have is that one stupid jpg
I think the inductance is high enough to lower the power rating quickly as step per second increase.
My math on the subject is rusty, and I don't want to look stupid
But the chart says constant current driver at 24V
well and that's in unipolar
plus I'm using bipolar series
which would be slower than bipolar parallel
I think this 6 wire motor is part of my issue, since the company stopped carrying it
You can't get parallel on 6 wire.
I know, that's why it's in series
you'd need 48 volts to get that chart in bipolar.
can you up the current to the rate 1.5A?
my drivers max out at 35V
isn't there a current setting on the drivers?
even is the 4.5 ohm rating is for uni 32V into 9 ohms should get you to 1,5A
I have a screw I can adjust the current limit
they aren't constant current I believe
That is how I understand it.
so I should turn it up?
Is there another adjustment for decay?
they are set by some resistors I believe
Let me get the datasheet,
it should be setup for mixed decay mode
[03:14:45] <tlab> http://www.allegromicro.com/en/Products/Part_Numbers/3979/3979.pdf
did you build the board? Or is the the chip on the board?
I designed the pcb
is it the schematic on page 3?
BRB, I've got to check on an expecting cow.
np I think I'm really tapped out with what I have
this guy has the same machine and he's getting about the same speeds... with a little different drivers
[03:30:30] <tlab> http://www.britishideas.com/category/cnc/
ITRIPmax = VREF/8RS is the formula
hmm maybe it's my wiring is to small
The wire wouldn't drop with rpm.
I would be looking into measuring the actual current to the motors.
[03:41:36] <tlab> http://www.britishideas.com/category/cnc/
this guy was getting 10 ipm
later he posted 30IPM. But if the 10 works for you.
tlab, when you said .8A did you mean for each drive? Or total?
that was no load too, I forgot
that's when they were not on the machine
IIRC it should remain constant regardless of load or rpm. unless your drivers have the ability to idle, then less amps standing still.
well they pull more current sitting still since they are brake mode
are you sure? It takes more energy to move than hold still.
not with a stepper motor
The motor has full torque at standstill
(if the windings are energized).. which they are
I understand the torque at stand still. But to move requires holding torque+the torque to move. Does it not?
in a servo I think it does
I dunno.. I'll have to check the current
something for me to do tomorrow
Servos aren't blind, they use only what is needed. In theory anyway.
Chopper step motor drives behave a little like servos because the supply current will go up when
they are moving (even if the motor current drops somewhat) supply current <> motor current
[04:11:17] <tlab> http://en.wikipedia.org/wiki/Stepper_motor#Stepper_motor_drive_circuits
I'm pretty sure I have L/R drive circuits
Isn't the function of current control to keep the power up while fighting the inductance of the windings? That was my understanding
Most try to keep the current constant while fighting inductance and BEMF
pcw_home, thanks. I was hoping i didn't forget that much. I've been in a 2 week electronic,programming, and CNC refresher boot camp. Loosing my mind.
When a chopper drive motor is idle, the drive only needs to generate Rmotor*Imotor volts (its like a switching PS)
In this case you have a large stepdown ratio, so you may have .5A of supply current at 50V generating 4A at 5V in the step motor winding
For LR drives (unipolar?) the power supply needs to supply all the current at idle (to heat the resistors!)
The power consumed by the stepper should be constant, correct?
Yes, except it goes down at high speeds since the current regulation fails
That's what I thought.
So with a chopper drive the power input will go up with speed and load just like a servo
( the extra power generating mechanical work)
the overall efficiency is much lower than a servo however
Chopper drives are kinda new to me. ie I couldn't afford them last time I was looking.
I'm using servos on my design.
There are some really good and cheap chopper drives now...
Other than tuning, servos are much nicer for larger machines
This is a test machine, just a bench top. Managed to get the servos and drives cheap, and the rest easily crosses over to larger machines.
Might have a Mazak slant to do once I can 'proof of concept'.
Whats a Mazak slant like? Is it a lathe?
yeah, slant bed lathe. Not worth fixing the control.
good screws and ways, just no brains
sounds like an ideal EMC subject
mazak can be pretty zippy too
It is a very nice machine.
I tried to convince the owner it would be best if I just got it out of his way, but no luck
That;s why I'm so determined to get the 7I48 card working, need lots of IOs
sentimental maybe, did they get quotes on fixing the old control?
They tried 4 times and it never worked, or worked long. Then they wanted $4K to ship the card to Japan, so they could try.
I got the 7I48 working well enough that I turned following error up high in the hm2-servo config,
and was able to "dial a voltage" with the encoders, and also checked all 6 encoder inputs
how old is the Mazak?
Not sure how old it is. Was going to go back and look, but forgot.
I've got hostmot2-firmware/ PIN_SV12IM_2X7I48_72 but after make nothing like 2X7I48 in the 5i20/
I know nothing of jeplers build script :-( Other than I really really like the idea
that it can build all the bitfiles and I dont have to be a mouse slave...
geo01005_home is now known as geo01005
in the interim I can just send you a bitfile (I have the one I checked with on my emc testbed)
I think I got it. somthing like ./build.py i20 XXXXX
You should be able to tell from the dmesg if you enable the debug option so it prints the pinout
Dont know if you have the latest source with the enables routed to I/O 0 and 23 (instead of GPIO)
I did that so the example hm2-servo HAL file would work without changes (other than PWM mode changed to 2))
he was on today and pushed some stuff for it, does he have the most recent? I'll change the PWM mode
Had good results with the computer build today. http://imgur.com/ue2ay
Under $200 and I can replicate it easily.
<jepler> anyway, I just pushed some accumulated hostmot2-firmware changes to git.linuxcnc.org including the fix to the .pin file generator and the corrected PIN_*7I48*
+++Quoted from earlier+++
OK that the latest (well other than my newer non-7I48 related changes)
Thats quite decent latency, what hardware?
atom 330 1.6Ghz 1g ram
It held those while building the firmware too.
Kernel is stripped.
Is that the intel D945mumble? I have one of those
night guys I'm going to bed
Yep, thats the one
It doesn't really like compiling stuff, but it is quick.
Might be a bit low on ram, swapped out a bit.
Is that with a SMP kernel?
SMP 64 bit
want the config file?
I dont think I'd have time to fuss with it anytime soon
Maybe you could post it on the wiki
I'll do that. I'm going to try and help with the docs as soon as I figure out what I'm doing.
Help with SMP support would be good for lots of EMC users. That intel MB would be quite nice for parport stepper
systems with that latency
Freaking near blizzard conditions, and I think the cow is going into labor. Prefect timing.
Other than that, I've got time.
Not like a commercial farm. A hobby farm or whatever people call it now.
Family milk cow
Arent you supposed to do your bovine umm introductions so the blessed event is on a nice April day?
She was artificially inseminated several times and didn't take. She finally got to the neighbors bull.
Cows seem to prefer bad weather to calve, less predators?
Ive heard of that for sheep as well (we have 4 weed abatement sheep)
I wouldn't worry about a cows calving, but they become pets when you work so close to them.
ah you mean mowers
the use sheep for kudzu abatement, the words linked.
No just weeds (California) I got tired of firing up the brush cutter every year
so we decided to get the sheep, they really are spoiled pets
Nature is easier to work with than fight.
Yes, our hillside that would normally be impassible at this time of year looks like a pasture now
Just hoping that theres enough so we dont have to buy hay by the end of summer
I know that feeling. This year sucked for hay.
I got a .bit but no .pin
My wife has wanted a cow but we dont have the space
pin files are just documentation
cows are great, ever have raw milk. straight from the tit?
well, not directly
stand still cow, my ceral needs milk
or walk in freezer to fit the cow for milshakes
No, goat milk but not cow
Never developed a test for it.
I dont much care for it either.
Though after we got the sheep I sort of got interested in sheep dairying
(something to do when I retire)
Is this the right file? Got it from jepler http://emergent.unpy.net/files/sandbox/sv12im_2x7i48_72.pin
I guess I don't need it.
And then this patch for the driver side. http://emergent.unpy.net/files/sandbox/0001-untested-support-for-muxed-encoders.patch
It looks like a pinout without the enables (notice the first and last pins on each connector are GPIO. not enables)
Yes you need that "untested support..." patch
otherwise the driver will not recognise the encoders
It this the normal in top directory " patch -p1 < patch_name "?
What is sheep's milk like?
Very concentrated normally used for cheeses/very rich yogurt
interesting, neighbor has several sheep.
which pins on p4 are GPIO the blank ones? Can the be designated?
dairy sheep are different (not much milk from most normal sheep)
blank pins are GPIO
can p3 be reconfigured for GPIO
Yes HostMot2 allows all pins to be GPIO
(blank pins are GPIO only -- no extra function)
Our two cows are both an old school dairy breed. Not as much milk as a Holstein, but much more hardy and less issues.
Nice chatting, hope your cow holds off until morning...
Same with the sheep, the dairy breeds are pretty fussy
I never quite got fully understood that out of the manuals.
what diameter would of Trapezoidal threaded spindle would you use if you would get them for free?
(for a home made cnc)
lengh is 50 cm
probably M10 or M8
but it depends on motors and how you plan to hook them up
hi got a simple quest it works but is this correct someone with stepper motors here !
quest is 4Cable 2coil A,B,C,D coil 1A/B coil 2 C,D
how do i now the right C/D or D/C
or simple does not mather either
use a meter to check coils
thats ok thats good!
yes it does matter to the driver
so how can i find out
the coil has 1,6ohm
I cannot know your driver
lets say it in colors coil A green,black - coil B blue/red Driver is L298
i wire it ABCD green black blue red
what will be if i change to green black red blue
is ther a international color code of the stepper motors?
sealive: if you have the order wrong it will: a. not move at all, b. move backwards
usually it's trial & error till you get the right order
the coils are messurt with the meter thats ok so the coils are correct only the way they are wirerd
there is a thunderstorm coming up so i got vto go thanks fpr your help
hey -- Look at this!
[14:19:28] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=100264
I have a feed override knob that outputs 4 bits that then filtered through wsum I get 0-12... I didn't see any place in EMC to use this to control my feed override, did I miss something?
scale it to get 0..1
then use adaptive-feed override
or just link to halui
JT-Work: the issue with using halui is the multiple control points issue
I looked at halui and it only takes up or down signals
if you set the slider to 50% in halui, then what happens if someone sets the slider to 75% in AXIS
I don't need the slider actually
well.. it's the reason why only up/down is added to halui
it's best to use an encoder for feed override
and just use 2 pins, hook them to an encoder component, then halui
then I can't tell by looking at my knob what it is
so motion.adaptive-feed I'll need to have the slider to 100% for my knob position to be correct
I've not had any internet at home since Wednesday some jerk wad took a bolt out of my tower and it blew over :/
time to weld it? ;)
I used grade 8 bolts and peened the threaded end about 1/4" so it can never be unscrewed again
even by me!
time for a tower cam!
a neighbor doesn't like you having a tower in your yard>
I don't know who did it but you can't see the tower for the trees
weird.. Are you sure someone did it - and not just wind and rattling?
* skunkworks_ has seen odder things..
positive, they put the bolt and nut side by side on the concrete base
* JT-Work wishes there was an INI setting to use an external feed override knob
halui can do that with an encoder - it works great
can you look at the encoder dial and tell what your feed override setting is?
no, but it moves the slider on the screen so they can all work together
you could make a display to put by the knob, I suppose, but I doubt it would be worth the trouble
yea, the knob all ready has the 0 - 120% marks and it is right below the spindle so it is in your hand while you watch the machine run
I have one like that on my Analiam too and use it all the time without looking at the screen or away from the part... really slick
then I would think - adaptive feed pin..
I sympathize but I still recommend an encoder
then it will always be whatever percent of whatever emc is set to. ;)
the feed override override?
the k&t has something similar... But I think I will be going with an encoder. I can't wait to be able to give it a spin..
JT-Work: you can disable some feed overrides
maybe you can disable the GUI one, and just keep AF enabled
alex_joni: I don't follow
[14:59:58] <skunkworks_> http://www.electronicsam.com/images/KandT/conversion/frntcontroller.JPG
Notice the 'fast' on the knob. ;)
there are some G-codes to disable overrides (I know you can disable AF and SO overrides)
not sure about the regular feed override
that way you can make sure your GUI Feed Override is always at 100%
so it doesn't scale your AF knob
skunkworks_: I love that control panel. I still wish you'd keep the thumbwheels for mdi.
heh - no thank you!
or are you going to get rid of the whole box?
I love the tape reader :D
that's so cute
the whole box. we are looking towards arm with monitor/keyboard and mouse. (I think axis is going to be the gui)
skunkworks_: mocca + hardware buttons
Dad for sure needs the preview. (he loves to see what he programmed wrong.) Hi dad!
hi sam's dad!
I like to preview at my bench with another computer running AXIS, then when it's right, I transfer it over to the mill and use touchy there
he just retired this week - so I think he should get the conversion done in a few days ;)
yeah, he better get busy then
what does the M50 Feed Override Control turn off?
that's the feed override override
it turns off the feed override
JT-Work: think about tapping with a floating tap holder - You don't want someone to turn the feed down and screw up that calculation.
cradek: I bet he thought you were just joking about the feed override override
i_tarzan is now known as robotito
is there a spindle override override?
so turn M50 off and use M52 from my feed override knob and scale it to 0 - 1
and have the slider on 120% so it matches
JT-Work: hmm.. that'll be tricky
but the slider will not move...
you need to hack AXIS for that
skunkworks_: it will if you hack AXIS
JT-Work: one disadvantage for M50 is that you need it in all programs
you must learn to not fight the EMC way. you will find peace and serenity if you simply comply with EMC's wishes and do it the easy way.
take sharpie, scribble out 0 and 120, and stick an encoder in there, and it'll work great
you usually just click it up or down a couple clicks anyway - who cares what the number is
sometimes emc should bend to needs :)
fiddle with the knob until it stops that infernal squawking, then look at screen and note the setting... reslove to fix the program later, then forget...
if I'm not 100% sure of a program I put it at 10% and watch then at 100% when I'm happy I didn't screw up the g code
JT-Work: I like to use max velocity for that kind of checking
I usually use it to "drive in" every new tool if I've fiddled with the offsets (max velocity hooked to the wheel)
cradek: but your a brave guy with no divots in your machines
I watch every approach... I drive it with the max vel wheel, and stop it an inch or so before where I think it should stop, then check DTG
(if I've messed with offsets lately)
is there halui support for max_vel ?
hmm.. I love my new printer
what kind is it?
JT-Work: Samsung CLP-770
it's really fast
although once that wasn't an advantage.. I sent a PS document for printing, and it interpreted it as text
before I could stop it, it printed about 60-70 pages of jibberish :D
my printer does that if I try and print from Ubuntu
hmm.. it works ok here in a multi-OS environment
only win printing through samba/cups doesn't quite work well, but I stopped bothering why (some bidir driver comm issue)
yea, the printer is on my windoz computer and I used to be able to print from 6.04 I think
yea, that one LOL
* alex_joni runs home
it's the week-end ;)
er, it's 9:30 am

it's 5:30 somewhere :)
yep, right around alex I think
it is slowly getting to the weekend here.
cradek: which mesa card did you use for the bridgeport?
skunkworks_: I think it was a regular 5i20 - it was seb's and I think he took it home with him
I think the machine has 7i33 and just one 7i37 in it
one of them has screw terminals, the other didn't - we kind of dug around for whatever we could find :-)
he did the wiring - I just stood around, squinted at schematics, gave advice, and drank tea
sounds like hard work
heh - nice. still can't believe 11.5 hours
that is awesome work.
chris is being modest - he told me what wires to connect where, i was just the tech monkey
11.5 hours for what?
convert a older cnc bridgport to emc
I should do that one of these days
first I need a mill to convert though :P
you have to remember it took him less than a month iirc to convert his jr.. That is impressive.
it's very simple: just convince chris to tell you how to do it ;-)
I want to make an engraving mill sometime soon
I think I'm setting the other conversion record
the secret is have schematics for the machine
maybe 2' of movement or so
havent decided if I want to try making a tool changer... heh
no - I think I am... ;)
just reaching the 4 month mark on my conversion
paid $250 for jr's schematics - worth every penny
I want to use something like this for the spindle... http://www.artcotools.com/compete-nsk-e3000-series-spindle-system-60000-rpm-pr-16758.html
it is really _really_ quiet
I'm not really motivated right now though :(
is it like a dremel?
that is... heh.. much quieter and expensive
I installed a lesser model on an omniturn with C-axes a while ago...
270watt motor from the same company
(BTW, unless its dirt cheap, dont get an omni-turn)
maybe it would be better with a different controller
my conversion has been a few years...
hmm.. I cant decide if I want to go get a pizza, or make waffles with my new waffle iron...
waffles with swiss cheese and brown mustard on top
bleh... that sounds nasty
stoneground brown, nothing fancy
I could make my own pizza...
never made my own pizza before..
oh, meh... it takes a while for the dough
ugh! I cant decide
pizza is easy and tasty if you have the right recipe
[16:27:58] <JT-Work> http://gnipsel.com/recipes/pizza/pizza-sauce-fresh.html
what about the dough?
I use the dry mix from the store
oh, I dont have a blender either
I use DeMontie crushed tomatoes no blender needed
meh... thats what the kitchenaid mixer is for...
and tastes just as good
for making pastries like pizza dough :P
I need to update that page
only one teaspoon of garlic? :/
can never have too much garlic
screw that! 40 cloves baby!
how many cloves are in a bulb?
justin__ is now known as JustinXJS

archivist: dont forget the garlic!
pickled garlic I could eat all day
WalterN: Spindles make good blenders/food processors
with what? a 3"diameter corncob rougher endmill? :-]
I'm trying to change the PWM type on the 5i20, in file hm2-servo.hal i'm going to the the line.
setp hm2_[HOSTMOT2](BOARD).0.pwmgen.output-type 2
under the line
setp hm2_[HOSTMOT2](BOARD).0.pwmgen.pwm_frequency 40000
MarkPictor: were you the one having trouble with a parallel port not having a bidirectional feature available?
cradek and jepler: still having trouble with the parallel port
ok... I'm going with waffles... I'm feeling too cheap to buy a take-n-bake pizza, even though its payday friday :P
heh, guess so
heh, yeah was just writing that :)
did you update your git? there was a mistake.
yes I updated after you emailed me
what version do you have now
the correct format for config is 'cfg="out 0x378" right?
downloaded on 2/24
is there a git command to show what revision?
when I try loadrt hal_parport cfg="out 0x378" I get PARPORT: ERROR: request_region(0xffff) failed
isn't that a different error?
MarkPictor: how are the drives coming?
clytle374: yes for 7I48 output-type is 2
Also PWM rate should be 24 KHz (for full 13 bit DAC resolution)
yes but I get the previous error if I use cfg="0x378"
and I got this error before with cfg="out 0x378"
so it seems nothing has changed :-/
skunkworks: I posted a pic a few days ago, getting closer. now I'm trying to get a signal from emc
to drive it

:) yes - we lucked out.
some is getting removed - like the clutch/brake solinoids for x, z and b.
skunkworks_: I know you're just turning that thing into the worlds largest/fastest margarita mixer...
MarkPictor: update again. you don't have the fix.
skunkworks_: holy crap
skunkworks_, we expect it redrawn with EMC symbols :)
skunkworks: here's the pic I posted 2/23 http://imagebin.org/86154
I put out some rat bait blocks that are 1x1x2" - they're gone! Not a crumb anywhere. Could a rat carry the block AND climb up a wall at the same time???
MarkPictor: looks similar! neat. Run into any issues yet? What is the highest voltage you have tested?
skunkworks_, hydraulic diagram?
Jymmm, they eat fast
archivist: but ZERO crumbs remaining, not even a spec
well the cap has ~50 volts on it, just sitting there :)
mice leave crumbs
robotito: yes - for this.. http://www.electronicsam.com/images/KandT/oldkandt.JPG
archivist: That's what I thought, so they must have taken the whole block
I haven't done anything with it since my cnczone posts, and that was with a single 15V supply for all
Jymmm, I have seen mice wander off with complete biscuits/cookies
anything => any testing
archivist: That I get, but climb up a 13ft wall with it in it's mouth???
archivist: (this is an enclosed patio)
or other species
archivist: roof rat
racoons love bait
they will even open sealed bait buckets
I see the droppings
plus this think won't have the hydraulic spindle or servos also. bunch of stuff is leaving.
This is weird.... It looks like google is using a PNG for the visual aspect, and html for the textual.

they're doing some crazy DOM manipulation there.

I'd say it is. there's the (R) symbol, which isn't in the 'plain html' (link at top of page)
try selecting it starting at the *very* top of the html page, ouside the document page.
it doesn't select into the document's text.
they're emulating your browsers select, but it's not the same.
Dont care, it works for me =)
yeah, it works.

Can I pull the Mesa 5i20's 5V off the PC 5V supply? I didn't see anything saying it must be isolated.
yes and it generally powers the daughter cards from that too
it gets it from the bus, you don't have to hook up separate power
Good, that eliminates a power supply. I might get away with everything else running off a single 24V supply.
MarkPictor-away is now known as MarkPictor
clytle374: The 5V connector on the 5I20 is to supply power to daughter cards that may require more power than the flat cable can provide
(its a power out, not power in)
i found a dell pc for really cheap, but it's got a celleron processor. are there any notorious issues with cellerons and emc or poor latency?
i know it depends on the mobo and whatnot as well, but just curious since the celleron wasnt exactly their flagship processor
celeron might actually perform better in realtime - less cache
atleast I have had ok luck with celeron computers
i figured for $20, it's worth it
what speed is it?
i just wanna ditch my pentium 3 mobo with all it's goofy stuff on it like the isa slot and no agp or onboard ethernet or vga
if the processor is slower than 1.4ghz, i can put my p3 processor in there
i think p3 and celleron use the same socket
but it isnt that old of a dell, i think it's faster
i wish i can find a dell like the one on my lathe, that one is getting really good latency, about 6-7000
iirc there are many breeds of celeron - pretty sure the first were based on p1's or p2's so some might be p4's now...
this one is probably a mid 2000's pc
judging by the monitor and case
woho got my electronics working now!
i think it was just an entry level dell, but it isnt that old
pcw_home, so it pulls all the power from the bus, okay.
even reset and all works, im soooo happy
whats a nice tune for a video? :P
is this your first emc'd machine?
the cameras mic sucks so it even pics breathing
*picks up me
nah, its my 2nd :P
frallzor: just dub another machine's audio from youtube or something lol
:P that would be sooo lame
na, it'd be just like a Jackie Chan movie
Good Evening from Germany
what is the best way to get a cad/cam for emc2
i'am coming from ProE at work
ther are multiple cad formats on linux
i'am runniung ubuntu karmic right now
i did a Freecad install but draft is not working on ubuntu says yuri
why not continue using ProE then?
the Real world cnc a Minimill2 has Rhino as the cam
ProE is only at work available
i want to have a full running system at home
the first projekt will be CNC Nr 5
in full 4-Axis motion
now on cnc-4 with emc 2 axes are running propper
my x axis fail waiting for a new stepper
[18:35:44] <sealive> http://linuxwiki.de/LinuxCad
here is what wiki says
frallzor: what woudt you think will be the best for me with my 24jears of proE expiriens in open Gpl
sealive: no open-source cad program is anywhere as good as pro-e or solidworks
I have no idea, im a windows man
I use solidworks with solidcam
krushia_ is now known as krushia
Screw up narrowly averted, manual is vague. Or I'm misreading it
we would have just pointed and snickered...
clytle374: the manual is written by smart people, i can almost never understand it
but that's my fault for being unedumicated
sealive: try heekscad
aa-danimal-shop, LOL. That is probably the underlying problem.
Well the manual says can supply 5V, so yep, I'm an idiot. Glad someone stopped me.

Does anything other than the .BIT file need to be in the /usr/firmare/fw link?
dmesg is http://pastebin.com/RTYwATmU
Same result on sample setups too, it WILL load from the live cd
RIP: 0010:[<ffffffffa01ca01a>] [<ffffffffa01ca01a>] bitfile_reverse_bits_of_chunk+0x1a/0x22 [hostmot2]
I built the sample firmware too, so the samples not running proves nothing.
do they have to be in /src/hal/firmware?
do you mean when booted from the live cd, your home-built firmwares work?
No. Just noting the hardware is good.
so you're using a 64 bit home-built kernel and rtai and also home-built firmwares?
I'd just be happy with 64bit SMP emc2
yes, does that void the warranty? Need the firmware for the 7i48
its SMP too
no, because there is no warranty - I'm just trying to figure out what parts you can trust
clytle374: Yes, return to place of purchase for a full refund.
maybe you could mix and match - try your firmwares when booted from the live cd in 32 bit uniprocessor mode
I was joking!!!!
I might have to do that, have to build emc there too.
I don't see anything obviously wrong with bitfile_reverse_bits_of_chunk unless chunk->size is wrong
no need to compile emc2 for the livecd
it's already compiled and working there
clytle374: what distro are you on?
alex_joni, Ubuntu 9.10 I had to patch emc for the 7i48. Patches from PCW and jepler
I guess I could see if it even loaded in the live cd
on your kernel+rtai+emc build can you load the distributed firmwares successfully?
seems like those are two good tests you could do without too much work - it would narrow it down a lot
real good question. Let me find them brb
also it'd be nice if you could disassemble your 64 bit bitfile.o and pastebin it
I think you can do that with objdump -d
I don't thinl the bit file changes between 64bit and 32 bit, does it?
I mean bitfile.o which is part of the hostmot2 driver
it's where your kernel bought the farm
yeah, try objdump -d src/objects/hal/drivers/mesa-hostmot2/bitfile.o or whatever the path is
my link in /lib/firmware points to the .bit file in the mesa-hostmot2 directory instead. hence my original question
[20:08:29] <clytle374> http://pastebin.com/FesAXDNp
I think that's what you need for a run-in-place build
cradek: i think i'm going to pick up a newer pc to use in my mill, so i can use a real agp video card
i'll let you know if it fixes those issues i was having
did I brag to you Danimal-office with the box? :P
with the long program
frallzor: no, but you did brag to danimal-garage!
congrats again on getting it all working!
[20:22:09] <frallzor> http://vimeo.com/9763342
that was the point :P if you saw the silly vid or not :P
gotta reboot ERROR: Module hm2_pci is in use brb
frallzor: very nice! definitely much nicer than mine
still its very simple, just made more safe =)
btw that reminds me, if anyone wants new fadal parts, they are going out of business so you can get everything at 50% off
motors, controls, machine castings, etc
i have them looking for some control pannels for me
I wouldnt mine a nice jog-thingie :P
get in line! lol
i'm hoping he can come up with that stuff
Jymmm: too many digits
haha what? :P
Danimal-office: for you... 1-900-F*CK-YOU
Danimal-office: np, any time
YES! he settled for you!
thats the proper amount of digits
damn no nice pendants
[20:27:51] <Danimal-office> http://velonews.competitor.com/2010/02/photos/boo-bikes-headed-for-nahbs-a-photo-gallery_106219
got any nice tips for a nice simple pendant thats easy to use with emc2? =)
check out that bike, i got some of my parts on that thing
Still no good. getting fireware now.
frallzor: i think you can buy one for like $150 from a few places
i've been meaning to get one
but most seem to be used with Mach3, no idea how much work it takes to use with emc2?
just need to figure out the wiring... an mpg is an mpg
should work fine
all it is is a few switches/buttons and an encoder
well i gotta get some parts done, adios
used a factory firmware and got the same errors. It is failing on firmware load, correct?
yes right after the load
I thought that might eliminate the real time as part of the problem, but it can't be unloaded without reboot.

Hello everyone! Cradek, may i??
Anyone worked with arduino board??
nope but will do
i cant run the http://axis.unpy.net/01198594294
script for arduino Can someone help. error is in line 48 in python script
c = hal.component("arduino")
File "/home/justin/arduino/arduino-0018/emc2/arduino_6ch.py", line 12, in <module>
c = hal.component("arduino-adc6")
hal.error: Operation failed
Sorry, wrong paste..
RTAPI: ERROR: could not open shared memory (errno=2)
HAL: ERROR: rtapi init failed
That is correct
i needed to make a print from a pcb. i photod the component side and then the solder side. i mirrored the solder side and overlayed it on top of the component side in gimp. made the overlay transparent. just by luck, most lined up. a couple more transparent layers for traces and values completed it. may be handy for others to reverse engineer stuff.
heh theres an easier way to do that...
make pcb sides line up and such
oh oh oh
i dont have a scanner here but that'd be better, as i get a lot of ... cosine like error further from center of focus
registering can be accomplished by shifting rotating ( and some scaling because of different focal heights )
now for some hardware, i got a tool to hold end of bent leadscrew made up :)
heh I just realized I forgot the most important part :P no input/output for the parallellport on my box!
just need to do some cutting
plastic so it wont even be hard to do =)
cheaper than plastic
the case is plastic :P
anyone wotrked with arduino or other avr board
i got a line on one of these control pannels for cheap: http://www.payback.info/P1011229.JPG
that would be sweet for my mill
full keyboard, all the buttons, a pendant, etc
[21:59:56] <frallzor> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=162&osCsid=831d1ac14478e254b61da0c96411bba1
this should work fine with emc?
doesnt seem to use odd electronics?
frallzor: scroll down on that page, there is instructions for use with EMC
ah missed that
fuck me =)
no thanks, but i think Jymmm might be interested
f*ck you :P
* aa-danimal-shop hides from Jymmm
Any ideas where i should even be looking for the cause of the firmware not loading?
aa-danimal-shop if I get a pendant like that, could i get a connector to just attach to a second p-port? =)
i dunno, i never used one, but there is more than enough info there to make it work easily with emc
yes but no info why they supply that extra board "which connects directly to an extra parallell port"
seems a bit useless if it will work somehow anyway
i dunno, do you use a parport?
i think it might work better running off a mesa board
will be getting an extra just for this
could be wrong though
i dont know how encoders work with parports
jogwheel signals are slow - very easy to read with a parallel port
cradek: did you see that control i linked?
I just dont understand why they claim the board is needed to connect to p-port
yes, looks nice
I'd prefer touchy and no keyboard, but if you want to use AXIS it looks great
cradek: i do too much editing on the machine to use touchy and no keyboard
then it looks great
Cradek, may i? arduino .py script dont want to run.
why does it say EMC on it already?
i offered 400
bosko: I can't help with that right now, just leaving. I hope you get it going.
Quick if you can
i have no clue, thats not the actual unit i'm getting, the one i'm getting is brand new from fadal
(22:28:24) bosko: RTAPI: ERROR: could not open shared memory (errno=2)
(22:28:24) bosko: HAL: ERROR: rtapi init failed
That is from python editor when i try to run..
how goes it
I got internet back on I see
bosko: this is not related with python. you have a permission problem or memlock size problem
when I left off I had the mpg hooked up to the 7i33 but did not have any counts showing up :(
i cant run the http://axis.unpy.net/01198594294
script for arduino Can someone help. error is in line 48 in python script
can you help?
what is fsck?
hardinge says to run fsck manually cause of an issue
file system check utility
how do I run it manually?
jt-plasma: you type fsck
* jt-plasma runs for a terminal to type man fsck
but it's not good idea to run fsck for rw devices
jt-plasma: do you have the jumpers right on the 7i33 for differential quadrature encoders?
bosko: see http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI#Memlock_Size
Dan I'm not sure atm
jt-plasma: thats probably the issue
they are in the
* jt-plasma looks at the manual
down position for TL
your mpg probably doesnt have a+-, b+-, and index+- like your encoders on the axes
any chance someone here has messed with keystick and gotten it to do useful things?
right it only has A B 5v 0v
so it that rs422 mode?
i believe so
should be opposite of your axis encoders if they have a+-, etc
each quadrature encoder channel has it's own jumper
the axis and spindle have A /A etc
acemi, my lines are * hard memlock 20480 #EMC2
and they work :)
rtf says 8196 os enough..
bosko: can you run this problem with your root account
with sudo is the same
when i want to run hal, it says
arduinovcp.hal:1: execv(arduino) failed
arduinovcp.hal:1: arduino exited without becoming ready
aa-danimal-shop: at least it boots up now LOL
when i debug in py editor, then i got
bosko: does EMC run without problem
arduinovcp.hal:1: execv(arduino) failed
arduinovcp.hal:1: arduino exited without becoming ready
Emc runs as it should
did you start the realtime before to run this script?
I get a -1 for count :/
* JT-Hardinge reads the manual a bit
why start now? :)
when you run out of ideas then rtfm
Is that for me?
but it could be...
the mpg has resistors from the 5v to A and B, Dan do you have a mpg on your hardinge?
i wish :(
hmmm, the config only had 3 encoders and JT wonders if he hooked up the read for the 4th one???
JT-Hardinge: i found one of these control pannels for my mill: http://www.payback.info/P1011229.JPG
waiting to see if they accept my offer
would be perfect since it has a full keyboard
it won't work it has a feed override knob like mine :P
acemi: i think is a problem that my arduino component is not in the hal component list
before to start your script, start the realtime with "./scripts/realtime start" in EMC dir
that is what i got now
HAL: ERROR: version code mismatch
HAL: ERROR: could not init shared memory

that is weird. if i run halrun from shell, i got different error then from "./scripts/realtime start"
JT-Hardinge: you just cant win
after the "./scripts/realtime start" command, what is the output of "ls -alh /dev/rtai*"
yea this has been quite a challenge
so was mine
servo amp issues, turret issues, etc

make your own
one where you dont need to use wsum
using wsum is easier than making one I think :)
I see the problem
whats the problem?
dunno yet that didn't fix it
* JT-Hardinge gives up for tonight :/
LOL i ordered a coolant tank and pump from enco, and it came damaged so i called them and they sent another one, and that one was even more damaged.
but they felt bad so they gave me a full refund on it and let me keep it
maybe you're expected to nest them
Thanks to all, arduino works like charm. Next question. Is there any good editor for vcp panels in xml??
you can open, edit, and save xml files with gedit
sorry, but something with visible preview? is there something like that?
not that i know of
