* alex_joni goes to bed
anyone know .. forward kinematics...
to any extent
dmess: Is that anything like Lego's?
* Jymmm chuckles *
Ta da! New, improved, and back from the dead.
dmess, which direction is forward? :)
SWP_Away is now known as SWPadnos
Okay, I officially hate my ISP. There is NO reason I should lose connection this often.
Looks like it's back under a rock for me. Later.
zen zey vill haff a gut connexion
jepler_ is now known as jepler
morning all :)
<--------- SWPadnos, that way is forward -------->
<--------- or -------->
SWPadnos: Ya, that's right. Or is it left?
Time to lay off the Tequila, Jymmm
say it out loud
Or have you been taking the "Bush Speech" courses again?
"...poor boy you're about to cry"
you just dont recognise the lyrics.
OK - time to get back to important things
like my FreeCiv game :D
* Jymmm isn't a gamer
It's probably AC/DC or something
more of a folks song from 20 years ago or so
Hmmm - I can't think of that one off the top of my head.
[01:26:42] <Jymmm> http://www.fortunecity.com/tinpan/parton/2/dooley.html
ok, 200 years ago =)
somewhat before my time
Yes, I'm over 200 years old
* Jymmm shakes his head *
or Lazarus Long
There was a person, le Compte de St. Germain, I think, who was reputed to have lived for something like 250 or 350 years (I don;t remember all the details).
good call.... as am i
we are all over 200 yrs old...
In Mercury years, possibly (eve that's fairly old though)
well - 50-ish, so not *that* old
no in earth yrs... its ALL in your head
no it's not. You exist, therefore you are. I make no such claim
therefore, it's all in your head :)
past lives are archived in a random order and YOU HERE and now only remember selective ones
I have no recollection of that event at this time.
but have access to ALL and EVERYTHING...
ssssshhhh - don't tell anyone
its all in your head... REALITY is an illusion..in time...
time .... is cool to play with.... to know someting ahea of time and see it... in your melon... leads to thoughts of mind controled cnc in a hurry
ok, NOW who has been into the tequilia a lil early today
no.. the teq..stuff i WILL NEVER MENTION OR TOUCH AGAIN AS OF '97... was not involved..
It's later for dmess
thought IS stronger than deed
ever heard "In your head" by the Cranberries...
I think dmess has either hit the bottle or been to church this evening :)
(or he's listening to "interesting" music)
I want to know about the '97 tequilla event.
no you dont... wife droped me off after 2/3 a bottle teq that stuff a 40 oz ... a whack of chinese food and a 5lb bet on who could eat the most fresh cherries.... NEED I SAY MORE... i got rug burn on my head.....
barfing cherry tequilla/msg
i woke up the next day said "good mornin' " to my room mate ...he said .." i Doubt it.."
SWPadnos: Or hiw was hitting the tequlia in the church
I didn't want to go there
i belched 3 x on the way home... " PULL OVER... open door expell.... spit... CLOSE door
I'm sure it was a religious experience
les_w: I'm tired, but I need to chat with you regarding 'toolmarks' and deflection
les_w: I'll email you photos (tomorrow?) so you can take a look after the monkey suits leave
NEVER... will that foul substrate touch my inards...
i'm tired and a little sick, but had to work because the suits are coming from corporate
yeah email em
les_w: Overall, I'm having some REALLY bad issues - suspect operator
any one ever " nital etched" any pcs to look for material abuse??
?? I have heard of that...kinda rings a bell...but I forget
les_w: Yeah, I can't even get v cutting to be clean; could be CAM too.
jymmm ... matl??
included "V" angle
90 and polycarb?
how much clearance in the cutter??
I think jymmm is using cmt router v cutters. prob about 15 degrees clearance
single flute in that needs 25 primary 30 secomadry with .. "cold " air mist to eliminate the burrs
sucks the mat'l away from the tool
sounds reasonable...I use vortec cold air on acetal a lot
high + rake and wickrd clearance will get super finish
but in poly carb it wears out fast
wood router bits may not be the beat on polycarb...yeah
I use acetal if at all possible..cuts so nice
cut some today.
no a hand ground d bit is usually BEST
see what your getting and adjust to suit
Jymmm does not have carbide griding capability...needs to look at some plastic machinig sites I guess
I set up a diamond grinder for carbide spiral downcut bits in my production
mynlon is 33% nylon and the rest is quartx filler
they told me it was plastic
sounds more like rock
+/-0.001 all ovr the picture
it ate carbide.... with oil as coolant..water...tied it
they planned on molding these ... we were prototypers
dmess: In this case, it's MDF
90 deg 1/2" china special for the v-cutter
les_w: I have a call into Onsrud for the acrylic cutters
what's SY ?
MDF still needs alot of clearance to clear the chip... being single lipped
Ha! What "chips"??? It's *ALL* dust =)
yeah that's the ticket. Dmess seems to think you need more primary and secondary clearance for polycarb. He is prob right.
I havne't tried polycarb (can't find the piece I have), but acrylic is much cheaper; will just try to find a single flute bit that's made for it.
Acrylic is also alot nicer optically
if you could.... put raw mat'l in freezer overnite.... cut it as fast as you can.. and release it...
might be easier to get a co2 tank =)
yeah...I had to ream some acetaltoday...had to freeze it or it came out undersize
or dry ice
Onsrud makes bits specifically for plastics, just that they have way too many
the softer the plastic the higher the clearance.....
I claim no expertise in machining acrylic. It's nasty, and I have crapped up plenty of parts.
dmess the hight the clearance?
the more abrasive the plastic the lower it needs to be...
primary back clearance angle
Yeah, that's what I'm understanding from this catalog
followed up with suitibale secondary
also that most are single flute... I still need them to tell me what O and V flute means
if A piece of you dust slips under that edge.... it PASTES up quickly...
yeah turns to goo quickly
o is a carved flute/// v is a 90 deg gashed flute
[02:46:42] <Jymmm> http://onsrud.com/Products.asp?Action=View&Part=63-701
in school, I machined a lot of wind tunnel models for the space shuttle fuel tank from acrylic.
messed up some too.
was it fun??
That bit is for HArd Plastic (acrylic, nylon, pvc, polycarb, solid surface)
Fun? yeah I guess.
nylon is NOT a HArd plastic
jymmm you need increased feed/rev
how hard you feedin'??
dmess: HD is as listed, including nylon. SP (soft plastics): HDPE, HIPS, UHMW, ABS, POlyCarb, PE, Polystyrene, pp, actal, acrylic, PET, solid surface
i'll bow... but its not the same as the rest in machinin..
what's your feed? they recommend something like .005-.009
dmess: Just what they say in theri catalog
fenn: .005 what?
jymmm sez he can't go below 8000
8000 - 25K RPM
yeah 8000 and on the verge of slipping steps...
but 8k RPM @ 120IPM and I still can't get the chipload high enough with two flutes
ok... fine... 8000 x .005" = 400ipm???
[02:53:02] <Jymmm> http://www.plasticsmag.com/routing.asp?fIssue=May/Jun-03&aid=3784
he can't go 400...hence the problem
8000*.005=40 ipm, but that's the bare minimum with one flute
ahhh... do this.... 800-1200 rpm... .005-.009 chip load....
I think a cold air gun is in order here
dmess: minimum rpm is 8000
we make em you know...heh
add coolant to the mess... high in concntrate
fuck it... wheres the LOX when you need it!
jymmm can't you use like a power drill or something? :P
ok silly question.... my router is variable speed already built in. Now, what it I add in a seperate one inline?
no... flood it... then add a layer of isopropyl alchohol thinly and slowly over it
you'll probably just burn up the motor
Eh, it has a two year instant replacment warranty =)
go for it!
take it back to the store and say "it didnt work.."
LIGHT HER UP...
yeah torque goes to hell with open loop phase control at low rpm
Gonna love Sears! $35 for the warranty, can even replace it on a Sunday
do it to it
* fenn needs to get a round tuit
so many toys, so little time
fyi... jymmm you need to concentrate on HARD MILLING with those rpms
define 'hard milling' ?
you know, i still have not installed the colombo electrospindle. Hope to, after the suits come. Lots of torque at 0-24ooo rpm!
it is sitting on the bench
dmess you're shitting me..
you can cut that hardness
dmess it only has 2HP
we had an air spindle...
i could stall it with my hand ANYTIME
with your hand on a 4 foot wrench maybe
dmess what kind of feedrates?
no.. and no burns
machine wase capable of 3 m/min
whats that in IPM ?
* fenn has to use a calculator every time someone uses ipm of m/min
in a 24 x 16 x 8 envelope
inches/sec or meters/sec makes more immediate sense
ah, well I can do about 120IPM cleanly, though I can go up to 180IPM.
If I had geckos, I could probably do MUCH better.
this little thin hauled ASS
I'm only running the steppers at 28VDC
I have almost (but not quite) been able to think in meters per minute or inches per minute with out thinking much
and cnc SHAPE recognition stuff too
does emc do rotational offsets?
dmess: I don't have any cooling, so I'll hold off on the metals for now =)
33.9 imches to a meter..
kinda worthless if you can see that the stock is rotated and you can't rotate the part program to match
hard metals is ALL air blow...
fenn: I dont think a drill motor has the bearings todo milling.
I push the buttons wrong too
les_w: Just hit the halon emergency release and run like hell!
reminds me...I have to get better fire extenguishers for the shop
I am throwing a lot of HP in there
that means big fires
we had DMG machines ( lathes) with individual air motors as tools
* fenn pictures les barbecuing over the smoldering remains of his router
yeah...4 kw spindle and 5 kw servos
little wee 1.5" dia jobs running 1/2" tools
don't need much heat in the winter
* fenn wonders what you do with a 100kw spindle
fenn: paper or plastic.
Light Bulb... is there some gear box I could use on my router to get the rpm's down?
or maybe some other spindel
similar to what was called a Windmiller i believe...has its own generator
jymmm you're gonna have to get a lathe :)
there's no escaping it
eventually, but not just yet
unless someone wants to donate one
How would a light bulb help to get the rpm down? Put it in series with the router?
lol.... no no no the light bulb is dimly flickering above my idea =)
gears at 10krpm are touchy. Some belts work.
might help a little in series too... not much though
les_w: toother pulleys ?
you dont wanna spin a high speed DC motor slowly, they rely on the moving air for cooling
compound wound universal moters have crap torque at low rpm
i like "moters" better
ok, what about an alternative (low speed) router... does such a thing exist?
I was just thinking that
is a meckanical gerbox OUT OF THE QUESTION??
just a little touchy
jymmm the first thought that came to mind was something like this, but in reverse:
[03:22:00] <fenn> http://buildyouridea.com/cnc/spindl
[03:22:08] <fenn> http://buildyouridea.com/cnc/spindle_05/spindle_05.html
no reason. Gears at 10 or 20 krpm can be fun I guess.
and maybe a toothed belt instead of just flat belt
my themac tool post grinder uses a flattish cloth belt at 40 krpm
fenn: I already have the bearings too, but no lathe
jymmm cut bearings into a block of plastic with an endmill, (dumbass) :P
with crowned pulleys les.... not a viable option.. is it??
er bearing recesses, that is
yeah...the Themac does hav ecrowned pulleys
fenn: and what about the actual spindle hole goober?!
fenn unless you have a 6" long endmill I cna borrow
hmm you can prolly buy it from littlemachineshop
* fenn hunts for a spindle
* Jymmm hunts for a pulley
like on my drillpress, but miniture
oh, wait a sec....
my job du jour was to remachine a 3/8" face don 29 inches into a hockey stick shaed part.... 4 of themmm
[03:27:51] <fenn> http://littlemachineshop.com/products/product_view.php?ProductID=1625
wtf are they thinking with the plastic gears?
what is the name of those pulleys used on drillpresses where you can change the speed by moving the belt?
multiple vee groove pulleys??
Maybe a sherline pulley set?
* fenn has a pile of homemade step pulleys
conical pulley work too
sounds more of an option to me
doesnt have to shut donw to adjust
fenn got any pics?
are pulleys a direct size to speed ratio?
2 cones held apart... belt is in a carrier along the axis c to c doesnt change but i/o ratio does
Like a 4" pulley to a 1" pulley will reduce rpm's 4x ?
its all about surface speed
4 " over 12" surface.... 1" 3.1415" surface
where does the 12" come from?
4 x 3.1414
circumferance of the pulley
Jymmm: yes 4:1 pulley will reduce rpms 4x
ok.... my 8K RPM router with a 1" pulley connected with a belt to a spindle with a 1" pulley.
err router with 4"
ooopps screwed that up too
will doo 8k
so that'll get me 2K RPM, probably better chipload, but still doens't seem enough
so add flutes...
dmess: I made a typo, should have benn.....
jymmm i took some pics to spite you
ok.... my 8K RPM router with a 1" pulley connected with a belt to a spindle with a 4" pulley.
[03:41:23] <fenn> http://fenn.freeshell.org/camera/DCP_0591.JPG
fenn: well, wasn't that sweet of you... (bastard)
double or teipp;e the chipload
and here's some endmills that i'm doing absolutele nothing with: http://fenn.freeshell.org/camera/DCP_0592.JPG
fenn: I was thinking like those maybe 5 step but in sherline size
fenn: is that a tamatic collet I see?
bah it's just a 1/2-20 hole
* Jymmm bought #0-1/4" tapping head with collets for $175
some day i'll cut an mt2 taper in it
fenn: So, why are your mills collecting rust?
because i dont have a mill :)
fenn did you?
no, but these were $12 for the set
fenn good deal
yeah.. brand new, made by morse tools
i slaved for mine....had fullltime access to m/c's
actually.... If I can reduce the RPM, I just might be able to use the tapping head on my router too
cnc mill lathe... edm's....grinders... cylindrical.. ahh out front SMILIN' man... beautiful...
well geez that's nice.. a trajectory planner just falls out of the sky when you ask for it
fenn: Fine, I'll buy a lathe.... http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=3173
* fenn barfs
wow it runs on 12 volts
fenn (you should have seen the 8-in-3 mini machines they had.... just like that one but also a mill, lathe, drill press, and more

[Global Notice] Hi all. We're experiencing some hub <-> hub routing problems, we're looking at it now
[Global Notice] We're going to experiment with a bit of latency reduction, please bear with us.
hi everyone, i'm jsut having a play around here... is anyone here running emc/emc2 on a gentoo system?
alex_joni: i followed the link in that racing simulator movie.. woah.
* alex_joni didn't find the builders of the machine :(
had some web address at the bottom, thought it would be the guy who made it
heh.. yeah, tried that too :P
google was no help either
whoever it is, got lots of money to burn
nice servo's though
and nice dynamics overall
if you knew what company made it, their website would probably be totally worthless or under construction
based on my quick survey of the motion platform scene
[11:37:52] <fenn> http://vr.isdale.com/vrTechReviews/MotionLinks_2000.html
[11:38:38] <alex_joni> http://www.f1simulator.com/
kinda the same thing..
wonder what the F1 car is for
to sit in it ;D
to make it feel more real :))
honestly it looks photoshopped
like they never built it or something
there is a video though
it really seems to be working
the video features some of the F1 stars driving in it
montoya & ralf schum. iirc
heh same music.. must be the same company
[11:45:58] <alex_joni> http://www.vesc.nl/index_simulatie_en.html
these seem the guys with the software
you wield google with much skill
* alex_joni has lots of practice :D
the information is ALL there
you just need to find it :)
i read that somewhere once
fravia++ i believe
hmmm fravia seems to have become more academic
i wonder if the rally simulator sprays mud and motor oil in your face when you wreck :)
* fenn goes to bed
les_w: you around ?
fenn: it burns you to death :D
[12:19:12] <alex_joni> http://mediabefuto.transindex.ro/fellepok_szav.php?mid=833
- does this work for you?
looking at some DC motor to buy ..
i'm a little confused about type :/
alex_joni: any suggestion about flange type on dc motors ?
there are with or without flange
flanges type B5, B14, are these the 'standard' for all brands ?
what do you pros think about this ? do you think i can use it with metall ? http://www.step-four.at/files/technische_daten_basic540_2004.pdf
what kind of metall?
the copper of pcbs will not be a problem, but a friend of mine likes to use it for cutting aluminium or other metalls for doing spray"stamps" and other stuff
alu probably, but I doubt that anything above that...
25kg total mechanics weight..
pretty soft machine ;)
right now i have a 5kg total weight machine here ;)
i see 20
where you read 25 ?
Gewicht der Mechanik 20 kg
well, i get this baby as soon as i organize someone to get it. its used and was on some exibitions to demonstrate a proparitary software
cncuser: party ?
party ? :)
about the exibition :)
Jacky^: no, no party, borring exibition
cncuser: thats ok
ill pay 1000 euros for it
think the prize is ok
i think so ..
motors & drives included?
yes and a 20000rpm spindle
then it's very ok
lets see, maybe it runs under emc in a few weeks
what i also havent figured out is where to put it
as its going to be very noisy
when cutting metall
cncuser: something like this?: http://www.infodelta.it/meccaniche.htm
yes, looks similar
hehe, handsoldered smd, cool
small but nice machine
i brickt everything i tried to solder till now (some lm75, an atmega)
you could do some jewels job :P
but i think its no big deal to make a solderarm for a cnc :)
btw 1k euro seems very good price
i dont think you can find lowest around ..
cnc for metal work buy this: http://www.infodelta.it/fresatrici_autom.htm

I know.. it's emc based
whats emcbased ?
the code has common roots
do you think emc can control the stepfour ?

jepler_ is now known as jepler
* alex_joni goes home
SWP_Away is now known as SWPadnos
Jymmm: are you ?
Hi there Ray
hi rayh, SWPadnos
those bits finally dribbled down to your machine? :)
whats the best feedrate setting for X,Y,Z in relief carving ?
i mean, should all axis go at the same speed ?
you probably want the tool to move at the same rate, regardless of the direction it's moving
so if you're moving at an angle, the axes won't be at the same speed as each other, but the tool woll be moving at a constant rate over the workpiece
so, should be ok to use the same feedrate for all axis
yes and no. there isn't a separate feedrate for each axis - it's the vector sum of axis rates (and you don't have to worry about it)
you do a G1 F100 X5 Y2 Z1, and EMC will calculate the proper speeds for each axis to get the 100mm/min feed rate
nice xplanation, thanks
sure,. that is :)
i'm driving my axis at 30 inches/min
angles are not so clean , but i think torque isnt enough
is that the max speed, or your preferred milling speed
ive also found, circular toolpath (starting from inside center) prduce a bad result
could be backlash
yeah, never setted ..
or feedrate too high, or cutting force too high for the tool, or ...
lot of things :) yeah, I know
heh - no simple answeres here
answers. there - I can type if I concentrate
* Jacky^ need to get free space on his BDI too ..
100% used :(
i want to try adding another old 1 gb HD
your hard disk is full? - how big is it?
an old HD
is this just the machine controller, or do you use it for other stuff?
was looking at the partition BDI has created
no, I use it just for emc
I just got a successful debian install from scratch
check how much space is used in /var/log
(du -h /var/log/)
not rt or emc but problem I had wa to fast a burner.
yeah.. turn on the pc ..
It must have been skipping stuff.
just removed synergy cad to get a bit of free space (about 180 mb)
rayh, cool. you should be right at home with it (at least as much as a recent BDI :) )
i do not use it
see if gnome is installed - that's a big one
I think not
if you're pretty good with Linux, you can also dump KDE in favor of one of the lighter weight window managers
that should get you several hundred meg
i was thinking to remove kde, i'm using evilwm in my wk
only 19 kb of executable ! :P
you can also clear your apt package cache
I know .. already did it
I should be but I've leaned on the BDI pretty hard these last couple of years.
ouch .. /dev/hda2 3541936 3353920 8088 100% /
/dev/hda1 101086 16984 78883 18% /boot
thats are the partitions created by BDI installation
what mean ?
it means that you have a lot of logs, like XFree86.0.log, that you probably don't need any more
1.2 gb of log files ? how is possible ?
also old system message log files and things like that (ftp server, ssh server, http server, and those all keep access logs, as does the terminal, I believe)
how long have you had the machine (with this install)?
maybe it's debug output from emc
now I know what to do :P
you just have to look to find out!
yep - system messages
could I change the debug level in emc.ini, I suppose..
yes - it's in the .ini file
im back in sweden
cleaning a bit the HD
sweden ? nice. Will be cold :P
here weve a nice temperature for the moment
england were colder
I know.. Center-north Italy too
not here, were near the african continent
tropical weather .. sometime too much !
we have 2 mouths of winter at year
then, i'm using 0.50 as MAX_VELOCITY for all axis
and i'm always having issue losting step on X axis
lets try to slow down to 0.40
i cant wait until i get home since my mill is shipping
hey alex im back in sweden
damn.. this internet is a funny story...
* alex_joni set up the map this morning
and already there are 19 users there :D
[20:32:06] <alex_joni> http://www.frappr.com/emctheenhancedmachinecontroller
you need to add yourself there :D
maybe put up a picture of your machine..
i just need decent motor mounts and some paint
alex_joni: can you help me check in my changes, now?
lerman: let me try ;)
ok.. first you need a clean checkout (in a different dir).. ok?
* alex_joni looks for the cvs stuff to start a branch
ok.. tell me when you're ready to type the commands
Really, why? I just checked this stuff out to change it.
well.. you need to have a clean checkout, or it'll screw things up
cvs -d:ext:email@example.com:/cvsroot/emc co -d emc2-interp emc2
this will checkout a clean copy into the emc2-interp dir
It is checking out, now.
ok, next you'll have to enter the dir and issue:
I've entered the directory.
hang on.. looking at previous namings
to keep it consistent
cvs rtag root-of-lerman-interp emc2
this tags the current code version (as the root of the new branch)...
tell me if it worked
It seems to have worked.
ok.. now we do the branching:
(it worked :) )
cvs rtag -b lerman-interp emc2
ok.. now look under emc2-interp/CVS
do you see a file called Tag there?
think it was Tag.. might be similar
No. It is not there.
cvs update -r lerman-interp
Done. Now there is a 'Tag' file.
ok.. now your local folder is marked that it belongs to the branch
try a 'cvs diff'
cvs diff always tests the difference between the repository and the local copy
that is good
now copy the changes you got (from the other folder where you got them) to this folder
and try cvs diff again
it should show only the changes you made..
copy the changes = copy the files, overwriting the existing ones
Well -- In the process of doing this, I created a directory I didn't need -- so I deleted it. But I was in the wrong directory when I did that and I think I just lost all my changes. But, I'll look again.
oh.. fsck that :(
So, after I make my changes, how do I check them in.
cvs commit -m "changes described"
How long can/should the description be?
depends on the changes
if you only fixed a typo you don't need pages describing that
2-3 lines is usually ok
It might be awkward to enter a paragraph on a single line.
if you keep the changes short
the thing is.. the commit message should describe what you did
not implementation details or such (those should be in the file, or in some documentation)
more like: added support for AND operator
alex_joni: no, the commit message should describe WHY you did what you did
not like: added support for AND operator, this is done by copying the code for OR operator, and adjusting all the neccessary places where they did differ
lerman: and what cradek said.. the why ;)
alex_joni: you can always see what was done with the diff. What you need from the log is insight into the brain of the person who did it.
well.. seeing a diff might not always give you a clue what the changes are about
log says: "moved a hundred things around"
we say to ourselves: "what the hell was he thinking??"
yeah.. that's bad
* alex_joni gives the recent yabosukz commits as examples
nah.. "fixed bugz"
(I administer an RCS system for a team of programmers and most of them still don't get this)
lerman: still there?
I've had logs that said, in effect, "Changed line that said [C code] into [some other C code]"
that's even worse than "fixed bugz"!
anyway, sorry for interrupting
cradek: not at all
your interruptions are always welcomed :)
Yeah. My fingers and mind were off trying to save my lost work. I still had an emacs session going with those files and may be able to save my bacon. BRB.
Well, I think I have most of it. I need to reconstruct the one change to the makefile, add in the files that I didn't change, cross my fingers and "make" to be sure. But that's for later. Thanks.
* alex_joni goes to bed
SWPadnos: pretty ok i believe
cool. How's crapaHALic? :)
well, it's renamed to halgui and i'm supposed to commit it to the emc2 tree
well, it isn't "great" until i do it i believe ;)
That's in Python, right? (so any machine that can run AXIS should be able to run halgui)
yeah, python with pygtk and gnome-python
(i use the canvas widget from gnome-python)
* Jacky^ is writing an howto ..
how to ruin a daughter in 3 steps
[22:20:48] <Jacky^> http://digilander.libero.it/jackydgl0/annamaria.jpg
what i middes ?
3 mm ballnose bit
is that a depression or a bump on the wood?
looks pretty cool to me, Jacky!
looks nice the original
it looks good to me, too
too low details definition
i dont like :(
what did you use to convet from bitmap to G-code?
maybe 2 mm ballnose would be better
and how big is the wood piece? (the metal looks quite good
the piece is 10x7 cm
really not big
how many pixels is the bitmap?
(or is that original size?)
but look a the face on the right
too many lines
stepover was small
Jacky^ give me url tua home page?
i use parallel pass too ..
k4ts: there are not interesting things on the page, just some link
Hmmm. The important part of the bitmap is only 236x391 pixels, so you need each pixel to be about 0.2mm (on the wood carbing)
These look nice: http://digilander.libero.it/jackydgl0/photos/lab/img010.jpeg.html
SWPadnos: yes ..
biggest piece is needed too
for 3 mm ballnose
you probably do want a 2mm or 1.5mm cutter then (I'm no expert - just the math of a ball end)
yeah, i think so
also, you should be able to set the relief height a little higher, though it looks pretty good now
max Z was about 8 mm, but it seem ok to me
the problem are details
like the hair?
that's where you need the smalle cutter. the 3mm is too flat, so it cuts off high spots when nearby low spots are cut
Jacky^ perso tutte foto dal pc
i will try again tomorrow
maybe you can double the image size (or sub-sample in your bitmap->g-code program), and use a really small cutter
yes, wanna go to ask tomorrow for a small cutter
probably 1-2 mm wuold be nice
whew worked all day under the microscope assembling tranducers
hey les_w :)
readind that oroccos TP paper
I think till took down his site to fix the little GPL problem
les_w: ive a question for you
i'm looking some DC motor to buy
we sayd fox X 3.5 nm, .000593 Kg M^2
looking at some catalogue I found some motor
but cant understand the inertia value
for es. i'm reading 0,0026 kgm2
thats the rotor inertia
should I convert this value ? :/
or its ok as inertia ?
it seems the right units
but 5 times too high
how it seem to you ?
too high .. uhm
or the spec is in error
that is a very high number
i dont think
is it an ordinary dc motor or a servo?
tehy called DC servomotors permanent magnet
have a link?
[22:53:31] <Jacky^> http://www.brtbonfiglioliricambi.it/bcspres_it.html
catalogue is on the page, but is 2 mb
ok, if you look ath the pdf
see page 42
the model i was looking is bcs 70
let me look some more
can you give me a link to specs page?
the pdf file
[23:03:18] <Jacky^> http://www.bonfiglioli.com/immagini/simb_pdf.gif
the notes i've are:
X 3.5 nm - .000593 Kg M^2 , Y 1 nm 10^-7 kg m^2, Z 0.5 nm 10^-5 kg m^2
1000 rpm for all, and brake on Z motor
assuming gecko 340 as drivers (already buyed), i think the voltage is important too
not up to 80 V for 1000 rpm
can't get the pdf
but you read 0,0026 kg*m^2?
les_w, try this link for the pdf: http://www.bonfiglioli.com/pdf/bcs/bc0009/bcs.pdf
oh.. sorry.. myabe i missed the link
ok. very high inertia. You could use it, but max g would be .1 rather than .5
you linked to the pdf link image :)
les_w: more torque is needed ?
3.5 for X are not enough so ?
If you have high inertia, you need more torque yes
ok, ty :)
i will search more ..
les_w where be the suits?!
hey Jymmm :)
