I need help compiling emc2-trunk on a custom rtai kernel
what is not working?
note that I know next to nothing about compiling on any kernel other than the one we distribute
I get the following error
./modsilent make -C /usr/src/linux-headers-2.6.24-realtime SUBDIRS=`pwd` CC=gcc V=0 -o /usr/src/linux-headers-2.6.24-realtime/Module.symvers modules make: Entering directory `/usr/src/linux-headers-2.6.24-realtime' CC [M] /home/earl/emc2-trunk/src/emc/kinematics/5axiskins.o /usr/src/linux-headers-2.6.24-realtime/arch/x86/Makefile:15: /usr/src/linux-headers-2.6.24-realtime/arch/x86/Makefile_32: No such file or directory In file included fr
that paste didn't work
could you put that on pastebin or something, and make sure the line ends don't get mangled?
too much on one line
and no CR
sorry new to irc
no problem, just hard to read :)
[02:22:43] <LabRat> http://pastebin.com/m6cd20c22
haha i just made a video of this new control. the camera is focused on the screen, and you see my hands waving while i talk thru the demo. it looks like white fang & black tooth from soupy sales.
LabRat: what directory are you in when you run make?
this isn't even remotely like what I see when I do a build
what is modsilent?
not sure what you are asking
you run a script called ./modsilent. what is it?
your command line starts with "./modsilent make -C blah blah
oh hey - that comes with EMC2 ;)
wtf is it?
or jepler did something to make EMC2 work with it anyway
I don't know that is just the part of the make where the error is
There is much more before that I didn't post
120vac with a cap across the coil of a relay. If I remove power, will there be a delay in opening the coil?
LabRat: post the 1st error
LabRat: oh, ok - I thought the first line was invoking the make
tomp: I believe that is the first error
the "much more" is make going thru many other files successfully
yes first error, make was working fine for awhile
jmkasunich: for some value of "delay", yes
so, where is the actual kernel source (vs the headers referenced in the error)
but not more than one AC line cycle
LabRat: when you say "working for a while", you mean it used to succeed, and now it doesn't
jmkasunich: I just need 1/2 a second delay =)
or you just mean that it chuggs away for a while before failing
use a DC relay
SWPadnos: It's 120VAC going in =)
change the circuit then, silly :)
JymmmEMC: diode, cap, DC relay
chuggs away for a while then fails after building some of the mesa drivers
SWPadnos: Can't it's a fog machine
time delay relay
hmmm. then get a time delay relay
time delay relays are $10 on ebay
the fog machine was only $20
New, walmart =)
LabRat: your system is using gcc 4.2.3?
the linux source is in /usr/src/linux-2.6.24 with a link called linux in /usr/src Checking for compiler version now
I'm afraid I'm not gonna be much help
those system dependent symlinks confuse me
especially since I'm still running older stuff
is there a command to check compiler version?
gcc -v ?
"Pick B!!! Pick B!!!"
I am using gcc version 4.2.3
you compiled your own rtai?
4.2.3 is the default on Hardy
(apparently - that's what I have as well)
I'm assuming this isn't Hardy
yeah I wanted to see if I could get my networking working
it is hardy
what network driver do you have?
err - card
I even downloaded the source from linuxcnc for 2.6.24
so, did EMC compile correctly before you replaced our RT kernel with your own?
I did try compiling on the stock rtai kernel and it compiled correctly well at least emc loaded but I did not check it running the mill
but it compiled
and now it doesn't
all the rtai tests work ok
and the problem is a header that is not included from EMC source, it is included from another system header
I just can't compile emc on it
FWIW, asm/types.h doesn't include anything on my system
and the only features.h files are part of xen
SWPadnos: are you looking at the same pastebin I am?
/usr/lib/gcc/i486-linux-gnu/4.2.3/include/asm/posix_types.h:13:22: error: features.h: No such file or directory
I see hal.h including linux/types.h which includes linux/posix_types.h, which includes asm/posix_types.h, which doesn't exist
no, posix-types exists, it's features.h that doesn't
where is features.h mentioned?
I can read
line 9, the one I pasted ;)
ok, now that I'm done being blind
you said "asm/types.h" doesn't include anything, that was a typo?
you meant "asm/posix_types.h doesn't include anything"
hmmm. no, I think I checked the wrong file ;)
no this is weird my asm link in the header file that points to asm-x86 is broken now. I thought I checked it earlier when I was building the rtai modules
I fixed the broken asm link in the header files and now I am trying to compile again
now I get a different error but in same place http://pastebin.com/m46221781
in what directory is the ipipe-enabled kernel?
I see that you're using a kernel-headers dir, but you must have had a kernel-source directory to be able to compile the RT kernel
you may just be missing a proper .config file or something
source is /usr/src/linux-2.6.24
ok, and that's the RTAI-patched kernel?
is source location something I can supply to the ./configure script?
something like --with-kernel-something=/path/to/kernel
I am using ./configure --enable-run-in-place --with-realtime=/usr/realtime --with-kernel-headers=/usr/src/linux-headers-2.6.24-realtime
same for realtime dir
what's the origin of the linux-headers-2.6.24-realtime dir?
was that from a package supplied by us?
no it was built the the 2.6.24 source from you but compiled by me
linux-source and linux-headers are two separate packages
yes I know
ok - I'm just going on the idea that there's a kernel that was compiled from one place, but the headers aren't that place
so I'd use the headers from the kernel source you compiled and see if that helps
I compiled the kernel and header files at the same time
I guess I don't understand what you mean by "compiled the header filess"
I am using the header files from my compile
well, clearly I'm no help here :)
thanks for trying
if you can, you may want to pop back in in about 8-12 hours. there are others that are more skilled in this area who may be on then
I will do that, thanks
actually, something like 8-20 hours from now :)
(it's jus a little late for a few of them)
I was going to get on early but I wanted to try building thing over one more time
good man :)
I dont agree "<cradek> (there's virtually no use for a horizontal rotary on a cnc)"
Paragon, btw I have Vertex for my rotary but its the 5" ish version I find I can design on pocked/shape then rotate for n replications
one of the suppliers does a stepper adapter for it
archivist_ub: how good precision do you get with it?
(vertex rotary table)
there is backlash and play in it
I saw a figure quoting 10arcseconds for a vertex table..
which sounded pretty good..
I should re-engineer is for rotary use in the way I use it, but where possible I add gcode to get rid of backlash
that is a rather interesting technique
it has 90-1 reduction and seems ok on division but not measured yet, when I get time I will measure with an angle dekkor
Ive done the quick and dirty check on a high count clock wheel and its accurate enough
that a digital caliper over a set number of teeth and set zero, continue around wheel see if any variation
that shows up cyclic error from the worm
hm, I'd probably stick a encoder on the table.. toget absolute angle..
table has various backlash/play errors
really needs measuring fixing and compensating for
if you have a absolute encoder you can make a compensation table :)
its not good enough for small pinions as far as I can tell, as its concentricity has too much play
dont you compensate for that when you set up a chuck?
I use the morse taper in it
I see... that's probably not as good
and chuck setup is too slow
taper in the middle is pretty good
uh, but you only need to set a chuck up once..
unless you change alot
I want to get to within tenths of the center but probably only getting a couple of thou
I change nearly every job
a 4 jaw chuck would work for that ;)
too muck setup time :) as well
I just have arbors that fit morse colletts so will be as good as can be
How about one of these :--) http://www.dovermotion.com/Downloads/DRT100.pdf
just buy a much better table.
600rpm cute :p
you can turn with it
get a price on it for a laugh
and please tell us
Just sent an email for a quote...
I wonder where it compares in price with a UK house
OK how about this for a lough ... how much work would it be to make one? I mean one can make the coils on the lathe and rare earth magnets are reasonable on ebay what more is there? ;-)
I have a coil winding machine :)
So could it be done do you think?
but the locking against machining forces is the real problem
Heres how they work .. http://www.axsys.com/p-dcmotors.php
either good servo and very high torque direct drive
The great thing about them is there is zero backlash and no loss (heat) due to coupling losses etc..
hmm "limited angle"
Newall do a high resolution system for rotaries dunno how fast though
Would make for an interesting project.... what with the over 100 waiting in the wing :-)
I had thought of many motors around a ring gear (I have many motors)
Taken guess's on the price of DRT-100 .... winner gets to take themselves out for lunch :-)
£5000k seems a little low i know but I am a cheap b$%tard lol
I have to be a cheap bar steward these days
Tell me about it ... :-(
a lot of Denford Oracs on ebay this week
I saw them yesterday. I do like them but it's just collecting them thats the problem. Not to mention space being a premium. However I am thinking practice a little more with Starmill and then move to an Orac as it's probably the natual progression.
archivist_ub: What kit do you have in the workshop?
I need a cnc lathe, they seem a reasonable starting point to retrofit, dunno what Denford quality is like though
here we have quite a lot, but the place is going to be closed, Shaublin lathes, Safag gear mill, Mikron hobbing mc and my cnc
Denford are good lathes I have a Starturn with ATC here is a youtube clip of a not ATC version http://www.axsys.com/p-dcmotors.php
I took pics a week ago and must make a web page
The shop your working at is closing?
getting made repugnant
lol .... got anything lined up yet?
but gets some machines
may work from home
OK ... What machines are you scavenging?
so Im preparing a web site http://www.archivist.info/gears/
depends on what boss gives me
there is more than I can take home!
do you want a 1900's vertical mill
Are they having a sale?
we may epay some
Where are you based?
getting them out the basement will be entertaining
I way down in Kent
yes, few capstan lathes 4 mills a sliding head and presses in a tin church
mad boss dug out the basement and has a slope to let things down into
LOL ..... I thinking of getting into miniture gas turbine engines.
I saw some at Ascot the other day
Do you think there is a market for them?
I think the rotary needs to be "solid" to machine the turbine blades
there is a bit yes
na but tesla turbine maybe
The price of them commercialy is a bit prohibitive £1200 - £2000
I got the impression turbine blades is the costly part, lost wax casting and only a percentage pass the machining stage
I have been testing a homemade arc furnace for melting inconnell 618 for casting.
your part way there then
tesla turbines are blade less
I bought two arc welders and connected themin paralell the cables connect to grphite rods that burn at 3000C!
are you putting argon on top to keep the metal clean
or something like that
I built a vacuum chamber from down pipe to be used in vacuum lost wax casting.
That would be the plan eventualy. Early doors at the moment
if you always control the gcode to remove backlash and work against (not climb mill) probably ok to use vertex rotary
I have a small compressor wheel 30mm dia. Most gas turbines use a 66mm. but I am aiming to make them smaller. The other type of efficient compressor is the closed swept back blade type. this could be cut on a fourth axis with out to much trouble I would think.
archivist_ub: Like your website.
it needs scaled thumbs (quick and dirty at the moment)
Sure, but at least its a start.
and perhaps better explanations and a few newer pics, the bevel is crappy
Im thinking of the model railway crowd as customers
or I get a proper job
What are the gears called that have spikey teeth?
but I have to keep the boss guessing to make sure I get machines
epycyclic, for clocks
er wrong cycloidal
Paragon: that's cool :D
anonimasu: The arc furnace?
archivist_ub: I'd get the schaublin lathe ;)
(if you can get it $free/cheap
they sell for alot of cash..
Yeah they are very nice lathes
anonimasu, going for two I think 120VM and a 70 on stand
the 70's are very very sought after :)
Im hoping for 1940's Boley jig mill and the sliding head would make a nice cnc project
and the Mikron and a couple of Safag gear mills
archivist_ub: you should get the gear machines ;p
all makes small stuff
Guys got to abscond for a while cu soon....
not big gear machines?
there is another hobb in the basement a tiny Barber Coleman
40mm max on the Mikron
Oh before I go I would just like to ask ... Converting a rotary table to CNC. What issues are there on mounting the optical encoder on the table axis rather then using the optical encoder on the motor shaft?
mine is stepper so cant comment,but I need rear access to pull in the colletts
and these cheap rotaries dont have complete backlash removal, perhaps a re-engineer for cnc is required
Paragon: you need both.. I think
feedback dont work very well with slop in the geartrain
the motor will be ~
in large steps to compensate until the table moves.
hysteresis between encoder counts..
That makes sense. Thanks for the info. CU soon.
* archivist_ub hunts for the swarf (small pinion) he made yesterday
Just got back for moment... What about using a big motor connected directly to the rotary tables axis avoiding the the use of the worm gear?
Like this apears to be ... http://www.youtube.com/watch?v=23_cZpKa3XU&feature=user
thats the torque motor idea, needs sufficient for cutting forces
Does a planetary gearbox have a lot of backlash?
yes unless you deal with it
found my swarf (small pinion)
archivist_ub: Does the table in the link above appear to be direct drive to you?
could well be yes
torque motors would work
he does make a turbine but not inconnell in his vid
uh.. will a sieg x3 machine inconel?
Appears the table is using a servo, what is the difference between a torque motor and the motor in use in the video ... without stating the obvious?
as long as you are well specified in torque I seen no problem
torque motors are low speed motors with alot of torque.
while servos are higher speed and generally needs a reduction to reach very high torques.
Can they be driven in the same way as a servo with optical encoder etc?
torque motors are $$$$$$
Thought there would be a catch ... bummer...
and I very much doubt the sieg x3 will cut inconel.
Unless we start winding our own
Thats a good point (inconnel) is it tough to cut then?
just a bit!!!!!!!!!!!!!!!!!!!1
you talking about cutting it and have no clue?
forget machining. :)
No I was going to cast it ....
Or hoping to cast it ....

[10:42:59] <anonimasu> http://www.youtube.com/watch?v=QgsAyIVA75s
the second one gives you a hint
(I hope you can hear the sound of it)
I dont have any sound at work.. :p
Paragon: I didnt cut inconel but the people that does say it's the nasiest thing you can machine
OMG .... Cutting dry. The swarth from the drilling operation is probably worth about $30 hehehe
well, heat cycling carbide is not a good thing either.
Now this is using flood .....
[10:48:49] <Paragon> http://www.youtube.com/watch?v=YfZP2gVUEMQ&feature=related
_Poincare is now known as Poincare
Paragon: is there sound in that video?
Sorry... Yes there was.... it didn't sound pleasant!
sounds like you need a rigig machine huh?
I'd make wax molds..
I pasted a link yesteday about how they make turbine blades..
Use lost wax casting.
actually they forged them
then they coated them in glass for machining so the blades wouldnt get damaged..
this is if you look at yesterdays log
and search for myspace(that's where it was)
For the disk type ie all in one turbine could the be pressed into shape?
no, for blades..
for a wheel they probably cast them..
with some special process then balance..
I think machining turbine wheels has issues with microfractures and stuff
grind the slots then press the disk into mold press to form the blade curves. Would this work?
yes I got the impression the other day there is a high failure rate
that would work
The turbine disk I am look at is about 25 - 30 mm dia
if you can buy them premade buy them.
I could possibly cnc the blade profile into two steel block then heat the inconnel disk and press it between the blocks.
this is for single blades..
think boeing size engines ;)
I dont think buying is an option for this size. I would have to out source the casting which would probably cost $$$$
I mean look for a turbocharger with complete wheels that fit..
mhi td03 or something smaller..
and just buy wheels..
they know more about blade profiles then you do ^_^
they were talking about turbocharger versions at Ascot
The profile beleive it or not is not that critical. Some people still use stainless steel cut slots and then twist the blades into possition.
mhi td03 mitsubishi ?
uh.. for effiency it's pretty important isnt it..
there are a smaller size..
[11:10:28] <anonimasu> http://www.technologie-entwicklung.de/12-rotor1.jpg
This is the guy I got the compressor wheel from (Thomas) he had a spare of the one you see in the picture.
* anonimasu nods
well, the good points about having someone cast them is QA
how hot does your furnace get?
Thats for sure.
that you can melt inconel?
It's still in its early stages but I got it too about 2000C and the refractory cracked (perlite home mixed)
One problem is feeding the anode and cathode at the most efficient speed. At the moment I have only done it by hand. I hope to feed it with a stepper based on amps drawn.
Back in a mo....
funny ".I have melted tools in inconel but have never melted inconel"
Back again ... I in the market for a clamping kit and am looking at these http://www.rdgtools.co.uk/acatalog/CLAMPING_KITS.html
. Now this I know this will sound lame but how do I select the correct kit. I have measured the T-Slot on my table and it shows 18mm at it widest and 9.5mm at the top slot ( sorry for the poor explanation) I measured a t clamp which comes in at 14.4 ~ and 9.8mm ....
...Are these kits measured by the t nuts or table slots?
[11:40:22] <Paragon> http://www.rdgtools.co.uk/acatalog/CLAMPING_KITS.html
iirc its the gap but ask them
Dam number busy...
boo... I got a parallel cable,.. but it appears to be a null modem cable... I don't think this 'l work?
null modem is serial
different animal completely
no, null modem cable is always a null modem cable
* fragalot curses a bit
why make a 25pin connector if the admn thing only uses a few wires >.>
used to be 25pin
now 9 pin
parallel was a different connector till some idiot changed it to 25 pin
* archivist_ub going back a loooooong way
1970's 80's then IBM used the 25pin but swapped to chassis socket where serial is plug
* anonimasu ponders if he could hold down some acetal with vaccum
that could also explain why my usb to parallel connector shows up as COM3 :p
you mean usb to serial coz its a plug not a socket
it just had a DB25 connector on it so i assumed it was parallel

skunkworks_: did you say the other day you are working on milling your circuit board?
skunkworks, whats that pic supposed to be ?
it is a telescope 'motor'
jepler: yes - I have one side rough milled
hope to make it back this weekend.
A few false starts.. I had a plastic bag over the open vaccum holes.. The bit grabbed it and pulled it right off the table.

SWPadnos: what fun is that?
when and if this works - I am seriously thinking about having them made.
uh - the fun of actually having the boards soon, with plated-through holes??
does eagle have EDIF export?
incidentally, 4PCB also has $33 barebones boards - plated through, with soldermasak and silkscreen for $33 each (min 4 though)
I don't know - that is something I have not looked at (exporting)
I never got around to asking the Altium guys for an Eagle import/export filter, so now I'm curious about formats they may both support
oh. there isn't a minimum quantity of 4, you get 1 free if you order 4 or more (of the $33 each ones)
Just been contacted with regards to the DRT-100 direct drive rotary table. They want to know my life story before they will quote me the price.!!!!!
say its for a mil contract and you cannot discuss it further
tell them to hire a detective
tell them its a present for me
here is a snippet from the email ....
Please could you provide me with some information on your application from which we could confirm the suitability of this device. Please also let me have a telephone number and I’ll call you to discuss. Finally, please let me have your company details so as I can prepare a quotation.
they want to know what your worth so they know how much to overcharge you :)
they will fall off chair when you tell them its for inconel
just tell them you've already assessed the suitability of the device and would like a quote to do final comparison against other suitable devices
Right, off to the workshop cu all in a bit :-)
I wonder how long sf will be giving us multiple copies of messages
it seems to be down to two today
or maybe Jon E is special
and I wonder how long it will be until people get mine
I only get them from Jon E
Stuart had a double this morning
I just got two with the same MessageID from stuart
so you can be sure he didn't cause it
it's pseudo-random. I've gotten 4 of each from Jon 9several times), singles from some people, and this double from Stuart
I had a load saturday
I had one email that took a week to go thru the system
mine went through now I guess
I see yours chris
darn, I got outbid on these motors I didn't need. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&&item=190256561207
when threadmilling what kind of Z stepdown do I need per rev?
same as pitch?
sure, how else could it work?
I have this example on my control for a internal thread and the pitch is 1.5
and they step Z down 4.5 per rev..
CP IPA-360 IZ-4,5 DR- F500
seems very much so.
ah well, im just playing if it fails it fails.
how tall is the threadmill end?
conceptually, you can use any integer multiple of the thread pitch as the Z step
you'll just get a multi-start thread (I think)
until you run out of relief anyway
anonimasu: thread mill sample programs here http://www.lakeshorecarbide.com/pdf/threadmill-1.pdf
[15:08:23] <BigJohnT> http://www.lakeshorecarbide.com/threadmillprogram2.aspx
[15:08:33] <BigJohnT> http://www.lakeshorecarbide.com/lakeshorecarbidecomthreadmillspeedsfeeds.aspx
guys buy me a 4th axis
[15:08:45] <BigJohnT> http://www.lakeshorecarbide.com/faqforthreadmills.aspx
i just need a little one
my gcode for thread milling assumes A axis is leaning by thread angle , please buy me 5th axis
lets just go for broke and you guys buy me a 5 axis mill :)
seems to me that thread milling should use a plain old 60 degree tool spun and run helically
there is no tilt
it's exactly like single-point threading
that gives concave sides
I have an example
depends on the radius of the cutter
you could even take a single-point lathe tool and spin it
the one I have looks like a tap with no pitch
i suppose you could sharpen the cutter with a concave profile of some sort
I do use a lathe tool on a fly cutter
the thread faces get concave by moving a straight line ( face edge of tool) ?
hm I'm wrong aren't I
it's only like single-point threading if the tool is small compared to the hole
I first hit the concave side wall when doing an acme form for the worm I did
* BigJohnT gets out his OptiVisor with extra lens and looks at a tap and a thread mill
and I went ah!
hmm, they look to have the same profile 60°
BigJohnT: are the flanks straight or curved slightly?
they are straight as far as I can tell
Im assuming its only ok for certain tap radius v required dia
put the tap and thread mill together and look for light in the flutes
for v form
the only difference I see between single point and the thread mill is you don't have to make as many passes with the thread mill
can you rub a stone on it or dykem up a screw or something to look for high spots?
did that cradek
what size of thread mill?
I think they'd look flat if the thread mill is much smaller diameter than the hole
mine is 1/4-20
sounds like big enuf for a worm, so the visual inpection is easier
what's the diameter of the thread mill?
anyone have a pic of a threadmill ?.....never had to use one
not its target thread, I mean its own diameter
* BigJohnT gets a caliper
if it's 1/8, I think you'd need to hold it against an 1/8-20 tap (ha) to really see the difference
my home made indexable http://www.archivist.info/cnc/p1010245.jpg
it is 3 flute so kinda hard to measure but it is about 0.175"
I think it will match up with the 1/4-20 tap by definition
btw, thread milling is the same as internal threads on a lathe your just turning a different part
BigJohnT: it's not, because with single-point the tool touches the work exactly along a radius and nowhere else
no it's different because the cutter is disc-shaped instead of just a point
your spinning tool touches along the radius but also some more above and below
archivist_ub: that tool gave you a concave surface when it swung about its own axis , and boved along its centerline?
above it will make an unwanted cut into one side of the thread, and below, the same cut in the other side
tomp no it was an acme form another job
I thought the thread mill was just a bunch of single point tools stacked together
tomp but I tilt so guarantee
BigJohnT: it is, but they don't all touch the work radially
BigJohnT: it might be neat if you could blue up the thread mill and touch it to the tap. I think you'll find that the contact is not planar like you would expect
might be very hard to do/see though.
concave profile on the cutter would only work for one combination of pitch and diameter
wouldn't you want to check a threadmill against a die?
I just compared the thread mill to an external threading tool for my lathe and the profile looks the same with 20x
fenn: I agree
archivist_ub: is the tilt intended to make the curve flatten out? ( a shallow curve rotated along the lines thru endpoints until it is in the direction of cut, therefore flat )
SWPadnos: yeah I guess so
tomp I tilt to the helix angle
the thread mill AFAIK will work for any diameter bigger than what ever the min is for that mill
I'll bet the minimum depends on the fit you want also
bellow min is concave sided probably
it might appear to work, but I bet you don't get a good shape though
[15:39:24] <cradek> http://www.cutting-tool.americanmachinist.com/guiEdits/Content/bdeee18/bdeee18_1.aspx
'Thread grooves on the cutter must be precisely ground with a corrected profile to ensure the tool doesn't overcut the flanks in the finished part.'
'A larger cutter diameter, which is desirable because it improves tool rigidity and strength, requires a greater degree of profile correction.'
that is for increasing speed
archivist_ub: i didnt look at your program, but tilting to the helix angle suggests the A rotates the work, the tool is offcenter, rotating, moving in Z interpolated with A. no circular interpolation?
"One thread mill produces a variety of thread diameters for the same pitch without degrading tool performance and can be used for through and blind holes."
from lakeshore carbide "Q. CAN I USE A SMALLER THREAD MILL TO GENERATE A LARGER DIAMETER THREAD WITH
THE SAME PITCH (T.P.I.)?
A. YES THE IMPORTANT PART OF A THREAD MILL IS THE PITCH (T.P.I.) AS LONG AS
THE LENGTH OF CUT IS THERE THAT IS NEEDED."
I suspect that answer is only approximately correct
I suspect that it is generally correct except for extreme conditions
I suspect we suspect the same thing
I suspect we do
* BigJohnT needs to do some actual work :)

wife away? :)

is there a difference between threadmilling and internal thread whirling?
whirld peas ( my wish for 2009 )
whirling sounds like "fun", wheeras milling sounds like work
hmm peck drilling .5 mm is entertaining
what the hell is internal whirling
or however it's supposed to be spelled
google and one finds what seems a milling ish reference
i have no idea how you'd fit a whirling head inside a bore
OK fella's got the pice for the DRT-100 Direct drive rotary table .... Give it you best estimate ... http://www.dovermotion.com/SpecificProductFamilyPage.aspx?ID=5
pice = price
OK here goes can't wait any longer .... £3,511 + Delivery + VAT
oh. only $10k
yeah I think that's about 30k at today's exchange rates
Just paid by credit card .... Errr yeah right O....

Paragon: where's the encoder coupled? to worm or axis?
ones with collet chuck..
well, the ones where the workpiece moves..
tomp: I was enquiring if there was any benifit in coupling to axis over the worm so as to keep down back lash.
i use 'System 3R' c-axis. looks same. meant for edm, mounts on end of Z. encoder is on worm. it fails to see the lash between worm and ring. guaranteed to .001degree.
i think on ring is better but requires 'thru hole' encoder
'guaranteed' ( means i gotta go make it in spec)
I may have one of those lying around. God knows where though.
Back in mo ... Dinner is calling!

tomp Jymm thank you both ;o)
I just tested my L298 controllers,.. and my stepper appears to jsut dance arround, with hardly any torque
any ideas what it might be?
probably something is wrong.
wiring or too fast or not enough current
it's slow, driven by a 555 for now
wiring is no 1
wiring is right
i was just about to fiddle with the current
and steppers need to accelerate so its easy to be too fast
see pull in rate from datasheet
archivist_ub: this is at 2Hz..
300 should be ok
Yeah,. the 555 cct i just made does 2Hz,.. so meh,.. :p should work anyway
the current should be .4, and it's running at .45
also noise and layout (dont forget the catch diodes if needed)
anonimasu: I just got back in :)
this circuit should work just fine (pminmo)
all my soldering joins appear to be in order,.. can't really think of much else
apart from trying another motor
for what degree of "should"
archivist_ub: as in many people have tried this and it works just fine
the filtering part is a bit over engineered, so noise shouldn't be a problem either
I'd also vote for incorrectly wiring of the motor leads .. if you switch wires, or if one wire connection is bad, the motor will move erratically
that was my first vote as well
I checked all combinations i could possibly check,. I just swapped the motors and this one runs fine.
lol, for .4Nm this is pretty damn strong :p
ok then check unipolar / bipolar
all 3 are the same,.. I think this one is just.. factory build error i guess
Paragon: please report your opinions on that danaher axis. i'm very interested in a servo version (hmm those are all steppers with encoders!)
Paragon: now that tghe pdfs dloaded, i see they have direct drive. you wont have any lash with the direct drive models
mmm,.. how hot do these steppers get? lol
fragalot: .4Nm is always .4Nm..
anonimasu: I just thought it'd be weaker :p
ah Yes.. :p
but stick a shaft so youget some leverage ;)
I mean,.. I can't stop it with my pliers :p
a lever with teeth
I tend to shove a droll chuck on steppers to test (need to hold the steppers down)
warm to hot when not mounted on a machine

I think they are super long endmils..
why so long tho :p
ask me something else
hows the weather?
thanks for asking

archivist_ub: looks like an ebay photo
Sorry All got dragged away .... Darned Wife ;-)
CANOT TEST BECAUSE I DONT HAVE TEH POWER CORD
LVDT transducer ?
google is my freind!
yes two coils and an excitation voltage, they sense distance can be very sensitive
I have one here on my machine can do a few microns
I guess the object need to be metal right?
well photo doesnt tell me if pointy end is springy
mosaic, thats what netscape's product was called
Paragon btw fix router to pass port 80 to your computer and not give us the login page and your settings
I can just make out Main body = ADE 2001 and probe end = ADE2102?
lvdt can measure non metal, just solid is enuf
archivist_ub: Unfortunatly I am unable to change my router default port which is 80. Stupid huh....
Belkin router has admin fixed on port 80 ....
Paragon, yes but should only be visible inside and should route 80 to server from outside
Next question can this be used with EMC?
archivist_ub: I leave it open so I can connect from work.
my lvdt has a box reading it then gives limits as levels
or an analogue out
if 'this' is the lvdt, then 'this' needs translation to a number before emc can use it
Paragon my adsl router has whatever ports routed to whichever box internally as needed
could be lvdt->adc->emc
note box excites lvdt as well as its an AC device
ah, like heidenhain sine/cosine scales or a resolver
archivist_ub: justed logged into my router and trying to find where to make internal only for adm...
closer to resolver internaly as its coils
jon e's new adapter may be an i/f for it
maybe but likely no as its a linear device with one "cycle"
archivist_ub: Found the setting port 80 and 8080 is open as a virtual host could you try again please?
I mounted mine to do homing measurement
thats better Paragon
Paragon you may with to stop Welcome to the My Book World Edition Configuration Manager being visible
archivist_ub: Unable to do that at moment as I am using the Word Book's internal webserver as a place holder for my pages this is tempary until I install another tighthttp server and change the world books port to somthing other than 80
I use apache here
Its to fat for the WB's ARM processor hence tighthttp (less load on the processor)
I do prefer Apache as I understand it better.

Just took a couple of videos and some pics of my starmill and various bits. Yep messy workshop! http://srg.hobby-site.com/public/cnc
(Directory View should be on)
what quick change tooling system is that?
I think it's called Easy Change (EC).
DaViruz: Are you talking about the mill or the lathe?
and thanks :)
Take a look here it is still being sold http://www.royalprod.com/product.cfm?catID=11
The EC quick change system is used by twisting the bottom of the holder and inserting the tool holder 3 large ball bearings in the spindle (R8-EC) then lock onto the tool holder.
BTW did the vid's come out OK?
Good afternoon, folks. I've got a quick question.
Is there a cycle timer for a job, so we know how long it took to mill a part?
I would like to stress the workshop had nothing in it last week. Built the worktops and installed what you see over the course of the week. Wired up the Mill with new steppers and drivers and setup the lathes. That's the reason for the mess. The shop is only 8' X 19' so space is a premium. Just screwed a ply board to the wall so as to peg and place tools. It should be more organised soon! :-)
Ah, so buy the $25 Timex add-on, then. ;)
could you use the m1XX codes to run a stopwatch program?
assuming there is a stopwatch program for linux
cradek: how does one eliminate following errors on a stepper system? Change the base thread or something?
yeah there are probably various ways to rig something up
Paragon: there are various ways a stepper system can be misconfigured and get following errors.
I'll consider that...
cradek: No probs. I think Iv'e been through this before sometime ago. I'll go back to the manual.
Paragon, test latency some more
Paragon, I retuned the PID loops and eliminated following errors here. I was also able to get a faster speed as a result.
MASEngr: on a stepper system there are no PID loops
The loops were *terrible*.
Ah, whoops, I misread that as servo.
Thats for servo I beleive (or closed systems)
I think I need to do some more latency test as archivist_ub sugested. Thanks anyway.
Thanks for the answer about the timer, cradek. I'll see if I can hook something up.
How does one continue a nc program after stopping it at some point. I did right click and select 'start from here' The program started from there alright but did not start the spinlde as the m03 was at the top of the program?
there are various workarounds. you can start the spindle manually first (F9), if you have [EMCIO]SPINDLE_MODE=0
or, start at a tool change or other safe starting point in your program
toastydeath_ is now known as toasty
cradek: is SPINDLE_MODE in 2.2.6?
... I don't know
... I think it's not
cradek: Can the pluto-p board be used in conjuction with a second para port? I was thinking of running the stepper drives from pluto and a servo from a second para port. While I am at it can the spare pins of the port that pluto is using be used?
cradek: Oh and thanks for the info re : [EMCIO]SPINDLE_MODE=0
Paragon: I don't think SPINDLE_MODE is available if you are running 2.2.x, it's only in the development version
it's not in 2.2.x
Paragon: you can have more than one parport, yes, but I don't understand the second half of your question
jepler: I can install the dev head.
you should be able to use one parport with hal_parport and one parport with pluto_step or pluto_servo.
if you're asking whether a pluto can be connected to one parport while the hal_parport driver is used for another, then the answer is yes, it should work
but there are no spare pins on the parport the pluto is on
Ebay here I come ... Para please
if I understand your last question right..
toasty is now known as toastydeath
OK so the pluto takes needs the whole para port. Thats what I suspected but I thought I would ask just the same. :-)
it needs to, as it uses EPP to communicate
but there are probably some leftover pins on the pluto itself..
The pluto is only setup for 3 - axis right?
I might suggest looking at the Mesa 7i43 instead of the pluto. It's actually designed for use in an industrial environment
though I don't know the relative state of the driver
pluto_step has 4 step generators. pluto_servo has 4 PWM generators and 4 encoder counters. So on either one you could run 4 axes. On pluto_servo you can run 3 axes plus spindle motor.
(because running a spindle with feedback takes one PWM + one encoder)
I see. So could I run 3 step and 1 pwm + encoder? or is it all stepper or all pwm?
it's all stepper ('loadrt pluto_step') or all servo ('loadrt pluto_servo').
Ok thanks Jepler.
Just took a look at the Mesa 7i43 so is this recommended for EMC? I could not find the cost.
DUH just found price list
pretty cheap huh?
$79 - $99 not bad. Would I benfit much from this card? I alread own a pluto-p board
Paragon, if you already have the Pluto, then replacing it with the 7i43 may not make sense
the Mesa products are designed for actual use, not for experimentation like the pluto
the FPGA on the 7i43 is considerably larger, and it also has more I/O pins
Does it work out the box with EMC?
there is a driver, but I don't know how well it works at the moment
and I'm not sure if it's in 2.2.6 or only in TRUNK
I think it's in both, albeit under different names
Is it still in the dev stage?
but again, I don't know how close to finished it is
Thanks for the info. SWPadnos .
there's actually a pard programmer working on the code though :)
Would that be your good self by chance ;-)
it's Seb Kuzminsky
Peter at Mesa is also quite supportive of EMC (he answers questions and hired Seb ;) )
in any case, you should experiment with the Pluto, since you already have it ;)
I will do. It's a nice little card. Although I really cannot get my head around the language it coded in.
I think so
the Mesa stuff is in VHDL, which isn't much better (or worse)
Oh tahts the other one could'nt remember it
SWPadnos: any suggestions for how to start learning VDHL or verilog?
read some simple programs, look at some tutorials. that's about it unless you want to take a course
Just started reading this .... http://www.design-reuse.com/articles/7330/fpga-programming-step-by-step.html
there are also several tools that let you put C/C++ code into an FPGA
I know Altium does it now, and one of hte other major FPGA toolsets also
When I was looking at it sometime ago I did find it interesting. I think one needs to look at coding in another way then the now oop convention. A bit like moving from procedual to C god that hurt me. ;-)
there's one major thing you have to think about: parallelism
when you make an FPGA, all the logic you specify is there, running in parallel
at the same time.
then who will win the race?
when you think about programming in C, you may make a commonly used set of operations into a function, and call it from multiple places
when you make a "function" in an FPGA, you'll usually end up with multiple copies of it - one for every place it was used
10 LPRINT CHR$(12) 20 GOTO 10 "We dont need no stickin functions!"
or you have to explicitly multiplex the I/O to the module - selecting only one of the "callers" to use that resource at a time
Sounds like a party line to me
as for the race, well, that's a problem ;)
party on, dude!
oh hey - the author of that article founded Cybernetic Microsystems
does it compare to this at all? http://www.parallax.com/tabid/407/Default.aspx
I think they used to make a motion controller for steppers way back when
Afreinds 6yo used to call him "dude" all the time, so he would tell him: "I'm not your dude, dude, I'm your dad dude!"
the Propeller - no, not really
they have multiple processors (cogs) right?
yes, 8 IIRC
That run in parallel.
that's more or less like a multi-core CPU, with 8 cores
sure, they're in parallel
but so is the serial port in an AVR/PIC
so in one sense, they're the same - there are pieces of hardware that run at the same time
but as a programmer, you can't change what each of the cores (cogs) does
So the train of thought is similiar.
err - you can write code for them, but they're still cogs that execute some instruction set
uh - maybe
where as fpga is pure logic gates?
consider this: you write a program to calculate A = B * C + D
in a CPU, you'd load some operands, multiply, then add, then store
in an FPGA, there will be a multiplier with two inputs, the output of which is fed into an adder with two inputs
thus giving D
there will also be some enable / clock shenanigans (hopefully automatic) so the adder only uses a valid set of B*C and D inputs
giving A :)
ooops I meant A ... must be getting tired. lol
if you then want to have F = G * H + I, the FPGA will need one of two things:
either you add another multiplier/adder block, connected to the other inputs
or you add multiplexers so you can switch between one set of inputs/outputs and the other
so the optimization techniques are different for parallel systems like an FPGA vs. sequential ones like a CPU
(and I only know about 2% of what's needed to be considered an "expert" ;) )
BTW what I meant by earlier message was ... I started coding in 6502 assembly and then moved to C I found the transition hard to grasp. Mainly due to the fact that in assembly one needs to do just about everything where as in C there where function already available to call. The same whent for moving to OOP from C ie Java and classes etc etc
yah - learning a new syntax is pretty easy. it's learning which wheels you don't have to reinvent that's hard
hmmm. 6502 - Apple, Atari, or Commodore? :)
Commodore Vic 20 then commodore 64 > then 128 and finaly the good old Amiga. Saved all my pocket money for the US Amiga import. Oh how I miss the golden years! :-)
NO first one was the A1000 with 256k of memory. It had a base unit. I then bought the A500.
I never had one - just had a couple of friends with them
I had a TI 99/4A, then an Atari 800XL
Chipset names where Agnus, Denise and Paula ... lol
our high school computer club designed and built a memory expansion for the VIC-20 - a whopping 16 or 32k!
Your correct Agnes. Got it was a while ago.
don't forget Sid in the C64
Sid .... Sound Chip right...
yep. and the funky graphics memory arrangement
I loved the TI
I first started on an old Commodore PET which had a membrane keyboard.
say "this is unintelligible"
yep, and there was the SuperPET also
That had a proper keyboard did it not

lol .... The games where fun to play then. Is it that I am getting older or was the game play that much better than todays graphic intensive games?
Attack of the muttant cammels (Jeff minter), Elite (ported from BBC Micro) Arrr Nastalgia.
My peak gaming was doom 2
super pet had a proper keyboard and 120 character wide screen
I don't remember it being 120 chars across
i nursed on PET's vic's and c64's
it was certainly 80 (rather than the common 40 at the time)
I thought it was 80
the pet was 40
Love Green :-)
but the super pet had FLOPPY's yes GREEN some CBM's had amber
they also had 16k ram option for 32k
My first real job was working on IBM3270 mainframe's in the mid 80's. The elders still walked around dressed in white coats with pens in there breast pocket. Oh not to mention long hair and sandles. hehehe
not all pets were green screen
i swear the optomitist still sees burned in basic in the back of my eyeball
I still have my PET
was too modified to sell /let go
i still have a c64 in the original box somewhere
No way ... that cool archivist_ub , Ithink ;-)
added S100 bus and eurocard to it
had the 8k had 8k static S100 and 16k dynamic S100 in it as well
tested it a year ago and its slightly deaded 0k ram!
base 8 k probably or a buffer chip
Paragon: seb just joined..
Seb it's been mentioned that you are working on 7i43 board code for EMC. At what state is it at?
it's usable and ready to go in TRUNK. it's pretty miserable in 2.2.6... :-/
btw I was just reading this article. Very Interesting stuf http://www.design-reuse.com/articles/7330/fpga-programming-step-by-step.html
what are you trying to do with it?
(with the 7i43 that is)
Cool. I currently have a pluto-p board that I was going to play with but the 7i43 was recommended. It would be use to drive steppers and a servo on a four axis mill
both servos and stepper should work fine in TRUNK
i'm driving two of each, and using a third servo (with the motor powered off) as an MPG
this is on my test bench, i dont have it hooked up to any machines here yet
Can they be mixed? Ie 3 steppers xyz and a servo / encoder for A axis?
there's a firmware with 4 steppers and 4 servos, use any combination, whatever ones you dont want become gpios for things like limit switches etc
Seb do you know how much the delivery charges are to the UK?
no idea... mail email@example.com and ask, tell him i sent you ;-)
Sure thing Seb.
BTW will I see a massive inprovement with regards to motion speed. I think the limiting factor for me at the mo is EMC driving the pulses via the para port. The stepper drivers I have go to something like 52000 micro steps from memory.
or 5200 mabe
the 7i43 will be insanely much faster than stepping over the parport
Good stuff. Thanks again seb and all.... I'm off to bed. Night All :-)
good night :-)
OH one last thing what board shoud I go for I understand there are three version right?
Para only or usb / para ?
the usb part of the 7i43 is totally unused by emc2
i'd go for the larger of the FPGAs, and the board without USB if it's cheaper
When you say larger are they all compatible or do they need to from the 7i range?
the 7i43 is available with a 200Kgate FPGA or a 400Kgate FPGA, i'm saying i'd choose the one with the bigger FPGA
they're compatible other than FPGA size
make sense? i'm not exactly sure what you're asking
Oh I see. Thanks again Seb

LabRat: I suspect that emc requires RTAI_MALLOC=y at rtai configure time, but you have RTAI_MALLOC=m
archivist, that was the plan.... I have a rotary axis that I was going to add a stepper drive
LabRat: on your system, loading the kernel module rtai_malloc is required but emc doesn't know about rtai_malloc.
for better or for worse, emc is not able to use modprobe to automatically figure out module dependencies, nor does it use rtai-style .runinfo files; it doesn't always adapt to these different situations
archivist, then grind a cutter using a commercial pulley as a gauge
