why do you need such high res?
I have also found complete sets, but very small
what do yo mean "hi-res"? I typically work with 6MB 3000x2000x300dpi images
now, THAT's hi-res, but I dont need that good
well it's all relative... I like crisp graphics too
Jymmm what? something too good for you?
heck, this is way too small --> http://www.amuseyourself.com/goodreads/leonardodavinci/leonardo-self-portrait.jpg
and I thought nothing was ever good enough for Jymmm
* pfred1 just got a hell of a deal at Big Lots
I won't argue...if the pixel count on the retinal plane is less than the cone cell count..I agree it's not good enough
Leonardo Davinci wasn't he like a cross dresser and the Mona Lisa is a self portrait?
might have been
pfred1 Without DaVinci you wouldn't be here!
pfred1 he invented the screw
davinci and michelangelo were well...you know
I don't think he's in my family tree
pfred1 here as #emc
archemedes invented the screw
The screw? tell archimedes that
and that dope thought the screw was only good for moving water
nah just because someone is credited for an idea first doesn't mean someone else already didn't do it or wouldn't have done it the next day
the guy that put the lead screw on lathes is forgotten by history
everyone figures he was to odamned busy working to be famous
tho they believe he was French
not forgotten by me...Maudslay
little problem :)
les well from what i hear the very first guy no one knows who they were I guess Maudslay is taking credit kinda like Marconi
or Edison for that matter
who didn't invent half the things he claims to have
he was the Bill Gates of his day
stealing everyone blind left right and center
didn't get the better of George though now did he?
the phonograph is the real innovation I think of with edison
yeah but again he had the completely wrong idea as to what it was good for
he thought it was going to be for dictation
nah another frenchman invented the lightbulb
When I was in grade school I made one
got my homemade mill and emc running, but it's engraving backwards, i've edit ini and put a minus, swapped leads to steppers around, what else ?
tho Edison did vacuum it
from threaded rod and an orange juice can and some wood and AL foil
I was pretty thrilled
jerry maybe you should have olny reversed one thing?
or are you hoping that three wrongs will make a right?
yeah if you reversed everything it would still be backwards
let me run out and swap one back
yeah if it's odd an even fix won't do ya
or be forward from the other end
les man you should have seen me today fixing my Emglo
oh i had these big plans as to how I was going to do it until I actually started doing it
yeah Emglo is major manufacturer of gas air compressors
whats an emglo??
well they're big around here at anyrate
what kind of gas??
you know pull the cord it goes put put
oh i see....
* Jymmm knows push the button and it goes putt putt
portable air compressor
runs off a petrol engin
yeah only portable because it has wheels on it
thing must weigh about 300 pounds
i know the sort
and of course the hole in it was in the bottom of the tank :O
so I figure hey easy I take the head and the motor off of it
yeah good thing I didn't go with that plan!
the wheels only make it look like a few good men could mov it
they must bolt it together then weld the mounting plate to the tank after things bolted together
oh no plan B first off... nexer good
no help to remove the minus from ini anything else ?
because there's no way you're going to get the inside hardware back!
so I had to flip this thing over fully assembled
did you drain all the fliuds first
took the gas tank off but I'd already changed the oil
I had a coffee can catching what was coming out the breather tube
I guess it's really cleaned out now!
did you weld the tant??
it just had this little pinhole in it but I wanted it to be a flat weld job didn't want to play with side or overhead
ive got one set up but its too loud...
tho in retrospect I probably could have side jobbed it
jerry so how do you know your machine is running backwards?
we weld blind lotsa times
Dmess this is my compressor
if it was someone else's I'd have winged it too
we do it on our own and customers stuff
because the file i trying is a logo, harley-davidson, comes out, but you need a mirror to read :)
jerry and you've run the file in a sim and it's right way around?
hmm have you got an axis inverted some how??
jerry: Change the sign of the *_SCALES on either X or Y
not in the sim, but qcad shows it in the correct fashion
but not both.
paul_c: in the ini?
sign of scale sounds like the most likely culprit
paul_c if it's coming out a perfect mirror how is one axis going right and one wrong?
and why is z right?
is ther a mirror image parameter in EMC as on some CNC machines
Dmess it could be handy
I bet jerry wishes there was one right about now
is this file a piont to point program or does it hac g02 g03 in it??
where is the *SCALES, idon't recall that from ini
jerry grep -in scales *ini
INPUT_SCALES = 1000 0
hey cradek how bout a short how to on you image to gcode ?
OUTPUT_SCALE = 1000 0
paul_c: yea, just tried to change that from no sign to a minus, no change
(line 156 & 157)
change x and y to minus still assbackwards
in vi can't you find stuff by just goinng /term ?
There - You did both x & y
ah, just one
that's what paul_c has been saying
ok, i'll be back
tho it isn't the intuituive fix
* paul_c hands pfred1 a copy of emacs
you'd think if they both going wrong you'd have to change both
paul_c thanks but I prefer xemacs
RMS can go hang!
* paul_c sneaks a copy of word in...
sorry I don't do Windows
im new to EMC but an old cnc hack with 15 yrs and too many controls to remember
jerry: did you compile it?
* Jymmm installs EDLIN on pfred1's computer!
jerry: did you compile it successfully?
yeah i should be down in my mad scientist's lab working tonite but it's wet down there
any one here ever sen the TOSNUC 888 cnc controller
Jymmm I got a system with edlin on it
pfred1: XP comes with EDLIN btw
has like dos 3.3 on it or something
and Donkey Kong!
yeah too bad last time i fired that system up I had to spin the HDD spindle with a pencil eraser to overcome it's sticktion
and that must have been about 10 years ago now
someday I'll make a neat electroplater out of it
the 5V bus in it is not to be believed!
i had one here the dh was so loud the wife and kids would leave the family room if ifire it up
ah as I can remember it's quiet like the dead are
but it ran a 5 axis APT system so we had to have it to make G-codes
* cradek shrugs
still bassackwards, after changing x axis to minus, changed back to no minus, changed y axis to minus
are you changing the right ini file?
yeah when you change things and nothing happens you have to wonder
let me double check that
[hint] generic.run -ini foo.ini
Anyone read Italian?
I look at hot Italian women from time to time? does that count?
yeah - like who ;)
some how I doubt that; unless you know one of these italian chics that can read italian
SWPadnos, hot girls that are in Little Italy. :)
you been in there?
I have a sister that lived in Florence for 5 years - she may be able to help
OMG... summer time is the place to be.
A-L-P-H-A you like them with mustaches?
pfred1, they're Canadianized Italian WOPs.
Jymmm: are you looking for Da Vinci's low cost CNC router plans? :)
ohoh? free plans? I'll take a copy.
I want free.
Then consult Van Gogh's plans
though the accuracy isn't so great
SWPadnos, are you just making people now? Next you'll tell me there's a set from Raph, and Donatello.
And Mike - can't forget Mike
What about Leonardo...
We already went over Leonardo's plans - they're not free :)
time to try another day, need to find my copy of the ini files, now i'm getting following errors
short attention span.
I'll tell you - you really didn't want to work in a movie theater when TMNT or TMNT2 came out
what? you didn't like all the little boys that didn't shower, watching TMNT?
must have been a nice smell in the theatre.
I didn't like the parents who didn't care to actually throw out their leftover buckets of popcorn and soda
like "tip it over on the floor - it's OK"
so it's people doing it on purpose!
cradek: back to your proggy
stick floors is so gross to me.
yes it is
yeah - and there's no time to mop between shows
there's barely time to push a broom through the theater
I never worked in the service industry.
just lifeguarding ( beach and then pool ), and then as a programmer.
now a consultant, with a expensive hobby.
It's good to try those shoes for a little while - makes you a better person
SWPadnos, <shrug> I'm me...
jerry: so what do you want to know?
well - you're not good enough :)
or - you could be even better :)
hey, are still there
your still here...
jerry: did you get the mirror image problem fixed?
question about your image to gcode
nevermind - I missed one line of yours
SWPadnos: no, gave up for today, following errors now
so i need to find my copy of the ini
right - INPUT and OUTPUT scales need to be the same sign
ok, i'll make em the same when i fire it up in the morning
cradek: how about a short howto run your program
read the file named README
woo tonite is Mythbusters nite!
didn't get a readme, otherwise i would have read the readme
(that's it, in case you're still waiting)
where's it supposed to be ?
sorry, I wasn't reading what you were writing
I thought you were talking about the TrueType tracer
no, image to gcode
I see that, my mistake
well, edit image-to-gcode.py to point to your image (the input image is hardcoded!)
then just run it with python like:
you can tweak step and depth to get the output you want
cradek can't get it to read the commandline?
pfred1: patches accepted
pfred1: see the front page of my website under "Welcome" (http://timeguy.com)
cradek well it's just such a common thing that evne shell scripts seem to manage to do
yeah maybe wrap it in a shell script?
cradek: thanks, i'll gaive it a shot
I'm not saying it's hard, it's just that I didn't do it that way, and I don't care to fix it
my new philosophy is to share what I do, no matter how finished it is
(how finished it's not!)
ah take some pride :)
really, read my front page
we want kari!
if I worried about everything being perfect, I'd never share anything, because it never is.
I'm too busy staring at kari
cradek so you're disorganized are you?
so I'm giving everyone 80% of a finished image-to-gcode convertor, that actually already works.
there's value to that, and if I wanted to polish it up first, it would have to wait for "someday"
hey 80% is pretty good
someday I hope to be 80% organized
so people have to edit the file, or fix it themselves - if they can't handle that you don't have any business running a cnc machine anyway, so I don't care
cradek man it's got to be as easy as pressing the print button
I doubt I'm 80% organized, but I do finish most things 80%
well in demo we always say it's finished at 90%
because if we tried for 100% well sometimes 101% is bad!
whoops you mean we weren't supposed to take that down?
an 8 inch fire main can really let loose some water
you'd be suprised!
are we having fun yet?
* anonimasu yawns
SWPadnos_ is now known as SWPadnos
I gotta run
SWPadnos, you up?
* asdfqwega proceeds with trepidation - hacking autotrace to output splines in .dxf
Problem - scanning something to a raster image. Converting with autotrace to .dxf, it makes the splines into plines
plines with up to 10k segments!
Then, when I want to scale the .dxf to something I can use, I end up with LOTS of little lines
Qcad 2.0.4 can read splines, so off I go
I love it - I am re-learning C, figuring out the .dxf format, and reading somebody else's code, simultan-
...at the same time.
asdfqwega: check: www.wotsit.org
* anonimasu runs around in circles screaming
asdfqwega, I don't know of a program that can machine splines yet... so why not leave them as little lines?
hm, emc someday :)
Mostly is a matter of processing the file prior to outputting g-codes
some machines do splines
To keep a good approximation of the picture I'm scanning, I gotta keep the resolution up
However, autotrace outputs stuff in integer coords, where 1 pixel = 1 unit
So, typically, I have to scale things by 1/1000 in Qcad to get them into my work envelope
The problem is that autotrace has already converted to high-resolution polyline
probably a setting in autotrace to do what you want.
Scaled down, convert to g-code = multi-megabyte g-code file full of tiny, tiny moves
asdfqwega, that' slog down turbocnc, I know that.
wonder how emc would handle it?
with emc, sometimes it works, sometimes not
I think with not, it exceeds the max number of lines
working for anyone?
Plus, there's a certain amount of tweaking I have to do to the .dxf before I can use it - and I can't edit the polylines in Qcad
asdfqwega, you can convert the spline to a pline. you know that right? And then you can run an optimizer on the pline (lisp or vb)
this is in autocad at least.
* asdfqwega smacks A-L-P-H-A around with an Windows and AutoCAD EULA
I am not using Autocad!
that's bitch abuse... I'm calling the cops
I have a bitch? That's news to me...
I've been known to bitch...
Qcad (Camexpert) actually converts the splines for gcode output
but it's a lot more reasonable size
textdrive works for me
asdfqwega, works now.
but not all the servers being hosted there.
I'm going back to sleep
* anonimasu is listening to bach
I am having trouble..
I need some geek advice: How do you grep through a directory of files for something?
grep -R -e REGEXP *
don't recall if it's R or r
Oh, so I don't need to redirect it, cool
asdfqwega: where are you located?
Middle of Bumfsck, Egypt :(
can you try an address for me?
damn site seems to be down again
it's in TX
Eh? What's it doing?! No! NOOOOOOOOOOOOO~
morning paul_c *g*
* anonimasu hits the PLC
did you know that every problem you solve creates 3 others?
I've heard variations on that, yeah
I should take a break before I break somthing more.
anyone here interested in some cnc manuals??
Dmess: what kind?
what you need??
What you got ??
some of this and some of them...
fanuc tosnuc siemens heidenhain
next Q.... Will you be anywhere near Washongton DC at the end of April ?
ibeen every where man
im in toronto canada
Not that far north..
oh we still need the dog team...
at least till the ice breaks up
spring has sprung over here..
then we can break out the kayaks
here to the penguins are matin'
that how we can tell
but seriously what manuals do you need im going to ask my isp to let me post a few isos
the TOSNUC 888 has to be scanned and fudged yet
You looking at scanning them and putting them up as pdf files ?
you have an easy way to do that
not postin... just for friendly instructional / development principles same way i use them
Already have a couple of the TNC manuals, but others would be usefull for comparision.
* alex_joni agrees
ive worked on about 300 different cnc machine and control combinations in the last 18 yrs
have tnc 530i cd
You don't have any plans for attending the codeFest do you ?
Unfortunately NO Im hoping to be into a new workplace and possibly flying in our nat's out west so wife says 1 trip limit
tell her you're going to the pub ?
idunno... There must be several in the Gaithersburg area <grin>
oh... nahh she's seen me go for coffe and come back 3 days later without the truck...LOL
but we found out that a suburban is much more aerodynamic when its upside down
but you really gotta get into the air brakes to roll her back onto the wheels again
back to the manuals...
what controls have you run over
I played with a Burny
what the oldest??
Adolf Numerical Controls - Boxford used them on their lathes.
P & W Star-Turn Tape-O-Matic 1967 the yr i was born
GE 550,1050 , fanuc 2 & 3 & 5 & 9
heidenhain & siemens have most all their manuals posted on the web
too heavy for us little service guys to carry them all
damit... ANC appear to have disappeared from the www
ive never run over one ..odd
watch within a week... ; )
do you have a URL for the Siemens manuals ?
try this www3.ad.siemens.de/doconweb/
* alex_joni is back after a while
you wanna be flabergasted get into an 840D with foll contouring 5 axis
yup link still works
chk out the DMG Evolution Series of machine
bookmarked - The pdf links aren't playing ball with my usual browser...
ive got the doc on cd as well
which siemens do you have access to
don't have access to any Siemens systems..
have you looked at the live BDI - morphix based installation
im having a hard time getting it to stick on one machine
Give the BDI-4.xx a go.
(4.20 is the latest)
allways wants me to do an e2fsck and i did
Are you shutting down correctly before hitting the power Off ?
then its as if it duffed the FS.. becz it wont go back on at all even from the cd...
i throw 2.08 on.. then morphix live works again
im seeing a 4.18 no 4.20
Check the HDD BIOS settings - Set it to LBA mode for large disks...
fdisk wont let me clean it up
it sees an invisable logical drive in the ext dos partition so cant delete it
Not seen that before....
but the 2.1.8 goe asks if i want to remove data ..Yes.. go gone reboot system without a network or an ftp command...
band in the live cd... get it all..
its probably just something im yuckin up
the BDI-2.xx series are obsolete and are unlikely to receive any updates...
BDI-Live has been superceeded by BDI-4.xx
fine... hey any way to transfer scrips from one bdi version to another
gcode files ?
no under scripts... like loop
or the confersational programming module from 2.8.1
cp1 is included in BDI-4
tool offsets & work offsets are supported.
i have a full set of probing macros for the tosnuc 888 that might be useful to implement
all the tough stuff is done just have to re-assigh the variables
but what about teaching the work offset... you are here...CLICL
right click on one of the axis readouts.
ok i see
im a moron .. did i mention that.. to obvious for me
2.1.8 has a cute little scrip window with a teach button .. looks very pro
any support for user defined g or m codes??
M codes, yes.
M100 to M199
ok so probing with single m codes is doable
'pends what you are expecting a custom M code to do...
M codes (in general) should not be commanding moves.
call a parametric subroutine and pass thru some vars
then gimme some custom G codes
or developmental g codes possibly for later addition to the source
You have the source code ?
i have all the source parametric routines yes
and the source code for EMC
yes but adding to that at this point is above and beynd my capabilities
* alex_joni is back
paul_c: that's a nice one .. I'll remember that
these could be called as subroutines ... or am i incorect gosub...return
[17:02] <Dmess> have you looked at the live BDI - morphix based installation
[17:02] * acemi has joined #emc
[17:02] <paul_c> a little...
Dmess: paul_c did the BDI's ;)
alex_joni: YOU spoiled it...
* alex_joni hides
well good.. then i got the right guy.. ; )
* paul_c has the GPS coords...
right.. you didn't want Dmess to know that
and a LCCM
Dmess: if it won't work... blame paul_c
dont worry be happy.. its all my fault... i know it
hey i love the system and hope to run a little catia thru it soon..
one thing that BDI-4 has....
is samba client support.
Dmess: samba is a unix tool for Windows network support
supports Domains, workgroups etc
hmmm nice idea..
is there a buffered look ahead on the EMC

what do yur trolls eat anyway???
anything they can get their teeth in to.
odd... ours seem to go for the women and children first
must be all that soap they use
4.18 has Synergy included or support??? CNC too??
Dmess : Synergy as eval-version
30 day trial
nice.. anyone remember HELIX... cadcam??
apparently available as open source now but no longer supported
might make one heck of a system
Don't confuse open source with GPL, or any of the other FOSS licences...
HELIX? doesn't ring a bell
well it seemed i read they were making it available for recompilation ..but dont call us
big in mould making .. nice core cavity routines
right... I'm off to burn a fag or two, and grab a bun.
nice to have met you paul
I'll be back.
remember - don't burn the bun and grab the fags :)
sounds like a particular calif. guvernor...
how's it going SWP?
A little bit of a late night last night (and I still haven't finished that PC board)
bugger that ;)
yeah - at least I know all the parts are in stock at DigiKey
PC mount screw terminals are large
gotta fly later and thx all...
I can't find any screw terminals less than 5mm pitch, unless I use connectors (which aren't wanted on this board)
3.5 mm are commonly available
It shouldn't be a problem, but when there are 58 terminals on a board, it gets a bit big
I've seen 3.5 or 3.81mm headers, but not screw terminals (at least, not in the DigiKey bible :) )
Not sure we are talking same terms, header vs. screw terminal blocks. I was thinking of Digikey part # ED1514
right - I had seen those
I forgot to mention that I'm doing this board as a volunteer (so I don't want to define new components), and I acctually may need higher than 6A ampacity :)
(but that is the type of part I'm referring to)
proding routine example
opps sorry didnt mean to grab that much
is that a good heh
what is FOMT?
that's misspelled for FONT
(but why have a font of sin(x)?
after the IF lines - [VY=VJ+VX*FOMT[SIN[VB]*10000]/10000]
nope ist TOSNUC for function
OK. What is TOSNUC? :)
similar but stronger than fanuc
so this does a circular probe?
i believ tis probes a post... i dont remember off hand but i have a BUNCH of routines
auto tool length and the likes
auto tool length can be pretty easy, actually
at least in terms of the hardware needed
* alex_joni goes away
i have laser set ups as well
SWP: I have a full mirror now on my site
on all the BDI's
all the previous revs as well?
[15:42:53] <alex_joni> http://dsplabs.utt.ro/~juve/emc/
boookmarked.. ; )
I've got a closer mirror, but I haven't made it fully public yet (worried about bandwidth :) )
Dmess: should have plenty bandwidth here
take all you need
anyone used coil activation sequences... personally??
does anyone have a hinch on speed/feed for alu=?
care to share?
once I find the chart...
I'll be milling alu for the first time..
since I got my z working
12mm cutter run at ~1500rpm
hm, I'll be using a 8mm cutter
3flute 6mm cutter
more likely.. I dont know if I have collets for a 2 flute 8mm one
ok, that's the most my mill will do.. somwehere around it..
and you want a feedrate of approx 0.025mm per tooth per rpm
hm, how do you calc that?
0.025 3 3000
0.025 x 3 x 3000
hm much Z can I take per pass?
for slot drills, half the cutter Dia
for a 3flute endmill?
slot cutting ?
OK... Work on 30-50% step over...
and depth of cut = Dia
If this is a HSS cutter, reduce that by 15-25%
it is a hss cutter
OK... For a 6mm Dia cutter....
step over of 2mm, and DOC of 4mm
I am without cooling btw..
Climb mill and flood coolant to clear the chips.
or an air line to blow the chips out.
I'll do that..
with this CNC lark, you really do need a coolant supply...
I cant run flood coolant without a enclosure..
and I need better motor mounts and shielding to keep stuff out of my servos..
without coolant, I'd recommend reducing the feedrate
with ali, you will get a buildup on the cutting edges without some lubrication...
Got a can of WD40 ?
a few squirts will help.
will lighter cuts help?
hm, vital + the new spindle motor will help ;)
lighter cuts won't stop the buildup
anonimasu: if you have a real machine make big chips instead of making dust out of the alu
that means 0.1 or 0.2mm per tooth
with a 6-10mm tool
hm, how real is real?
real like the mill I found on a sale?
takes over 1 ton on the table
although I cant fit it anywhere..
bleh.. the hole I am about to make will take 73 minutes.
bigger cutter ?
it's a 52mm hole...
2" slot drill would do that...
I might aswell turn on the machine and then leave the reast to god and go and take a bath..
god/whatever evil that controls what happens
I dont think I need to pocket it..
I could just mill out the center part of it..
or order a boring head..
and drill the hole
hm, well I'll contour it out and then just facemill the whole part.. until it falls out..
that'll be faster..
hm, if I want to keep more feed what's the requirement other then flood coolant?
1 tonne, souds like a real one
yeah, but I couldnt fit it anywhere..
had a discusion with one who sells tools, a month ago
so I had to pass :)
and what kind of mill do you have now ?
a benchtop one..
whats that ?
not so much
or well that's what it says..
but I overdrive it from the vfd..
got a 4kw one on a shelve at work.
that man says don't cut to slow in aluminium, if you can. Than you will have less problems with getting the chips away and with the cutting edges of the tool
use a tool with max. two teeth
define that :
0.1-0.2 mm per teeth
or 0.3 :-)
with a 10mm tool
I increased my feed a bit..
cant sit and idle for 70 minutes..
17 is much better.
what type of tools do you have ?
dormer 6mm 3flute hss cutters..
I have some 8mm slotdrills aswell but I am unsure if I have collets that'll take them..
hardmetall is cheap today
or how is it called in english ?
yeah the carbide ones was double the cost..
hm, 10mm end mill hardmetall about 12 EUR here
the cheap ones
good enough for alu
dormer isnt cheap :)
but they are godo
ok for steel we take also the 80 EUR ones
our baby at work: http://www.digma.de/pages/dmasch_500.html
the hss ones are about 35eur
damn you :)
for HSS ?
16kW Spindel up to 40000rpm up to 20000mm/min speed
nice toy :p
that machine compined with TEBIS is realy nice
that machine is my example for building my one one
* paul_c wants the HSC800
I am looking at the demo when they mill a sculpture with it
I wonder what $ one like that would be
also with a polymer concrete frame but i have only some 1kW spindels from precise (60000rpm)
HSC800 too big
HSC500 compact nice machine
I'd seriously re-build my shop if I had enough money for a machine like that..
but way out of my league
stick with the small high speed ones :)
I doubt they are cheaper..
starting at $4800
starting at $48000
lol.. a new car is about 12000
or rather a newer one
Imperator_: these - http://www.datrondynamics.com/products.htm
I think les router works at about that speed..
have sean them on the EUROMOLD
wait - only $46,800 to start
Imperator_: any good?
hmm i was surprised that you can do so much with such a windy gantry machine
the moving portal is out of steel, filled with polymer concrete
ok if you compare it with a Digma machine it is a toy
but not bad
never heard about digma..
a small fast toy though :)
small company with very good machines
who needs a good car anyway.
I am looking at that tebis video
where they mill a sculpture
the Digma can do the same parts that can the Datron do in Alu but in hardened steel :-)
we can mill steel up to 63HRC
hm don't know ecactly but it depends only on the tools
brb.. moving out to the shop
have also to put some videos online from our Digma
have some nice videos
Imperator_: I am looking forward to seeing them
ask me next week
hm time to run this..
I broke a endmill.
hope the spndel is still ok
* anonimasu is annoyed
what happened was that I ran out of spindle power...
* paul_c spent �32 on a 3mm long series ball nose cutter....
Broke it in less than 2 mins of use.
and the table just snapped the endmill off..
I need to reduce my gearing or get a larger motor..
* anonimasu is tired of fscking around
always messing, with every little thing.. the only thing it's good at is milling foam..
or alu at 50mm/min..
but 50mm min means that every single part will take more then 5 hours to complete..
well, I better try again..
with smaller stepdown...
if I decrease the stepdown and increase the feed..
might that help..
hm 50 minutes.. of machining..
went up to 66
flood the table add isopropyl alcohol to the the mix
Dmess: that wont help..
Dmess: I have too little spindle power to make the chips..
what rpm and pwr have you got
or 2500 on the marking
lets see now ..
Should be plenty for a 6mm cutter
oh I know ...
should make chips... to get HSM you could add a spinner
(DOC x WOC x F x 1.34)/4 = KW @ Spindle (for ali)
but 6mm at 3000 rpm should cut hrc 45 without too much trouble
yeah that ...
is F in mm/sec for that equation?
SWPadnos: Units in inches...
OK - I was thinking the KW requirements were a bit high :)
getting 188 watts for a 1/4 cut
multiplyer... 1 rev in 6.2 out
though that's only about 3 CI/min per KW - is that right?
(CI = in^3)
hm, but I run the spindle at the max gearing..
I cant remember what ratio it is..
well time for another try..
sucking some digital photos in here
happened to get a good shot of congo and his pet chicken
he fell asleep on the porch and the chicken snuggled right up next to him
03petev * 10emc2/src/hal/drivers/motenc.h: Initial revision.
03petev * 10emc2/src/hal/drivers/hal_motenc.c: Initial revision.
I halved the feed
cuts better now
although I am making dust..
uh oh chip load low...
consider halfing the depth of cut instead
if you are power limited
course it will work with powder chips
just the tool dulls more rapidly
I decresed the speed..
to match better.
where did robin vanish off to?
He's helping Batman
ah of course
or running to Geneva about that stamp licking job or whatever he's pondering
03petev * 10emc2/src/hal/drivers/Makefile: Added files for MOTENC-100 board.
03petev * 10emc2/configs/core_servo.hal: Initial revision.
very high feed and lighter cuts..
to keep the chipload reasonable..
I had to do a lot of that with the turkey call production code
That's why I am getting a bigger spindle
pretty much time=k/kW
* anonimasu sighs
I got a 4kw one laying around at work..
the spindle rpm drops too much and the part gets scrapped..
because I lack the torque to maintain cutting at the higher chipload..
I decreased the speed to get a better chipload.. but a tiny bit too much and the spindle stalled..
I should get that vital and take 0.4mm cuts and feed at 1500mm/min
if you slow down the feed too much, the cutting load increases
hm, I increased it.. actually..
and decreased the speed..
you need to maintain the proper feed, and then set depth based on spindle HP
I need a new mill.
heh - if you really have a 1.7KW head, that's higher power than my Bridgeport
well I have it geared to get the max speed up..
so it's not 1.7kw at the spindle..
and I'm able to cut aluminum with a 1.5" diameter, 6-flute end mill
hm, the 4kw will be nice.
at around 10 IPM :)
I could go faster, but I can't crank too fast :)
how deep cuts do you take with that?
1/4" or so, a little less if I'm being careful
I wonder why my mill does this..
actually, more like 0.15 - 0.2 inches
I was taking a 2mm cut..
you have to calculate feeds and speeds in order
actually, spindle RPM, feed rate, then depth of cut
(shall I go on, or am I telling you what you already know? :) )
nothing of that is a probelm..
I know you should keep yourself to cutting data..
broke a few end mills myself...
but without torque you cant cut anything..
1.7kw is plenty of spindle power
yeah but it's geared at max also..
same amount of power
oh, but that gives a higher speed..
and less torque..
but you don't need as much torque with a smaller diameter cutter
the motor is rated at 2800rpm at 60hz..
(which is why you have the higer speed)
I might be running it too fast.
anonimasu never too fast!
I run 50hz@200% from the vfd..
too slow if anything (assuming 50 Hz)
loud fast rules!
what was your cutter diameter again?
was it high speed steel?
that might be a bit fast.
and hello yall
it's not the size of your tool but the skill with which you drill
(80/.340)*3.82=rpm or abouts
Im not sure what 6mm in inch is
" = 254mm
like Paul said, you want around 3000 RPM
and 2800 is fine, if a tiny bit slow
80surface feet per minute if its steel your cutting
(maybe run it at 50Hz * 130%)
aluminum, so 200 or so
yeah somthing like it..
if so I am running way too fast..
or 400 sfm or just below the melting point, it depends on your cooling
hand cooling :)
I could gear less.. and still keep the same speed..
to machine aluminum you need high pressure cooling to keep the aluminum from melting
and more torque to keep the spindle from stalling..
actually, you're probably having problems with the alu gumming up the mill
SWPadnos: the last endmill that broke was clean..
yeah use comprssed air
the spindle stalled..
and broke in 3 pices inside of the collet..
BTW - do you have any Tap Magic for Aluminum?
then use compressed air
bummer - it even smells nice
I have cutting oil..
aluminum is special
SWPadnos is correct, aluminum also has a tendency to stick to a hss endmill, an air blast with a water pickup line in most cases is enough to counteract a semi high speed operation
how about antifreeze (like for a car), or other coolant?
is just fine
gezr: that'll make it rust..
its aluminum right?
the machine that is..
yep - the propylene glycol is a little bit of a lubricant as well
wipe it when you're done :)
not if he keeps it lubed up
anything other then water/air is going to create a mist he may not be able to deal with
use antifreeze specially formulated for aluminum radiators :)
true - the machine should be covered in oils anyway
yeah but the table..
so should the operator!
and antifreeze is going to coat all sorts of stuff for the animals in the house to get a good licking
anyway, get a spray bottle, and give a squirt every few seconds to keep the endmill cool
yeah.. I know it's gummy,,
(gezr is right - use pure water)
its gummy because it melts while being cut
or isoprop alcohol ;)
yeah that's why you stream it with compressed air to clear the chips
the fact its soft in terms of a material doesnt help
water is cheaper
cheaper than air?
well, dosent matter now I am finished for today..
I'll cut lighter cuts at a higher speed.. instead..
you can use butter
gezr how about whipped cream?
wont it sclale if I increase both speed and feed..
that may work anything to help pull the heat out of the chip the moment its formed
f you have it, soluble oil
really you need special tooling for aluminum
yep.. got that..
* anonimasu yawns
No need for the screwball mixes then...
can get it off work for free.. as much as I need..
anonimasu we have lots of air here
it's about 50 miles htick or so ...
* robin_s got his press today
robin_s printing seditious literature?
pfred1: 50 tonne, 2m CNC pressbrake
pfred1: I use the interent for printing seditiuos literature ;)
* Imperator_ wishes anonimasu good luck, and goes to bed
yeah night Imperator_
I am done milling for today
I'll continue tomorrow..
anonimasu: made chips?
robin_s: yeah broke a endmill and almost another one..
alu is nasty..
gummed up huh?
I didnt know if I had the collets for my 2flute long slotdrills..
the first one took a too large bite..
and the spindle stalled and broke..
broke the endmill..
you G0'd it into the work?
anonimasu: You using long series ???
it was clean the i hit it out of the cut it took..
paul_c: I have for milling plastics..
although I havent tried them yet
Long series, you would need to reduce the feedrate by 50% or more.
thats more like it
is that better for cutting alu with?
although it's long ones.
best is a single flute :)
4cm flutes ;)
assuming you have enough revs
plain old tungsten tipped 'straight' router cutters work ok
ah you're back
hm.. I guess I'll make another try tomorrow
oh I am already home
hmm.. I am curious on how much I can get the feedrates up..
60 minutes for pocketing a 2d part in alu feels like forever..
maybe I could do 600mm/min and lighter cuts..
but the part will still take about as long to make..
0.003" per tooth
you have, 3 flutes?
0.009" per rev
27" per minute
thats what, 600mm minute @300rpm
sounds about right on feeds
what cutter dia?
you could go 0.5 dia steppdown
so 3mm steps would not be unreasonable
my mill cant cope with that..
3 flutes might clog though
that'll be too high load and stall the spindle..
I had a 3hp spindle on my router
I have too little torque to make it work..
3 flute is most rigid tool for the size of the chip pocket
at 12000 rpm eith a 6mm single flute ...
Dmess: in alluminium t3 flutes is not optimal, needs mreo chip clearance
this is 6063
i had an F-mach toshiba minimum rpm was 8000 went to 60 0000
single flute works best at high rpm
make chips, not dist
thats the key
get your hand on an international minicut end mill
hm will 3000rpm at 1000mm/min work..
0.003 per chip
I dont know why I do chips in inches
believe it or not ive run 350 rpm and 120 ipm in 4140 prehard
it sounds too much..
using a hitatchi cutter on a toshiba mill.....12 per tooth...
0.12 per tooth
0.07 = 6000rpm
trade show sjow em up deal...
my crane driver today was a compleat tosser
brought the press
* anonimasu is curious if this will work..
i sti;; have some of the sixes and nines from that show...
slung on uneven lifting slings
so when he lifted it .. all the oil pissed out
as it tipped up
wont use him again
you do installations??
not as such
justmoving a press to my place
Amada Promecam 2m / 50 tonne
weighs about 5t
not my nicest machine
top of the list is my Trumpf laser :)
but its yours...
its sort of mine
technically, its my mate Andys
but its in my unit
thump thump thump
[23:11:22] <robin_s> http://www.rapidcut.co.uk/images/LY2500.jpg
thats mine :)
mm, the press just goes <squeeeeeeze> bend
the punch .. now .. that went THUMP THUMP THUMP
nice laser... uses trumpf control>>
B220 series control
hey heidenhein is ... now
on a mill?
siemens 840 d
has 2 pIII cpu's
one for operator interaction one for the cnc
this Bosch has a big CNC lump
and a seperate "intelligent VDU"
as with most dedicated cnc controls
all the documentation is in german
lovely... older siemens used to be that way too
well, its not all in german
we have some notes from its previous owner
are the #'s in german??
in ... Dutch
LOL we had one machine land from japan for a show.... it had a japanese control
we ran it for the show and told ppl the english one was an option..
kanji and 16 bit floppy formats...
had to swap out one of the japanese engineers floppys into my box to get programs into the machine on the floor
last big show I went to was mach2004 in the UK
trade shows SUCK the big one for application engineers
yeah, I can imagine
never enough time and 3 too many machines
"will your machine do this?"
<insert partly formes description of complex part>
will it do it in 1 minute... hmm lets see 500lb slug on... 45 lbs finished sculptured part
kanji is tough
infact, I enjoyed mach2004 so much ... I bought mach2006.com :)
sure but the CLAPPER option is a might costly..
i never learned kanji i just remembered what did what from the english control
im a hand over hand kinda guy on alot of them
"click here to home the tool at full speed straight through the work envelope"
aahm, a demo engineer .. :)
Z - y x by retatded default
demo eng is not my favorite title... but i have demod my fair share
I saw the Mazak stand ... that was amazing
that was a HUGE machine
it was at CMTS too when their big un blew a belt trying to keep up to me..LOL
i bet i had 200 ppl around 1 machine at 1 point..
everything sounding like mildly controlled crashes
if the tool survives, i guess its a success
I've attracted a crowd on an NYC sidewalk plating Robotron
made 2000L of chips... just for shits and giggles...
it was funny when i just walked away from the game at like 2 million
toshiba mpf series
old Williams game sequel to Defender
I remember defender
i dont wanna remember the $$$ i put into defender
and my fave, "firebird"
I was never any good at defender was OK at Robotron though
i had an old 486 with emu for all the old games
totally different games
till the kids started using it...and then the mommy board said she was done
mame...thats it.. is xmame run in x too??
it's a game emulator
not so sure how easy it is to get ROMs for it anymore
but Robotron doesn't translate to keyboard controls very well :(
Joist is really cool on a PC
that was a good one... Quix too
I got a ton of ROMs someplace on a CD
remember the funny story behind "donkey kong"?
it was supposed to be "monkey kong" .. but the firm that sprayed the cabinets screwed up
in the end, it was easier to change the rom than change the cabinets
Engrish strikes again!
[23:39:03] <pfred1> http://www.engrish.com/
you may have noticed though, it had a lot of monkey, but not much donkey inthe game
well i never knew that...LOL
the game's name evolved was that it was supposed to be "Monkey Kong", but due to a barely legible fax transmission, the screenprinters created thousands of pieces of artwork that read "Donkey Kong" instead. Since the manufacturers were in a rush to get the game released, they opted to change the game's title rather than wait for the artwork to be reprinted.

i have some good engrish in a pail in the basement...
must go reload it... but which reel of tape do i unmount...
flench.. thats it.. a plus tard. mon ami
how goes it?
pretty good making desktop backgrounds out of some of these engravings in these PDF files
ah, sounds cool.
I have to rebuild my desktop.... either the hdd or the controler is going out
that'll take about a week
i noticed some in the 4.18 install
