wonderful. we won't have to do the email dance then. how many machines have you retrofitted?
This is my second EMC2 project. Learning curve is still a bit steep in places.
I try to stay connected all the time, I used to click "away", to grey myself out, until I discovered that it blocked incoming messages. I could say KimK_afk I suppose, but I seldom bother. So just post, and I'll scroll back later and catch up.
Does your toolchanger look like the one on Kirk's Shizouka?
Kirk is here in Cali if i recall correctly.
OK, that's a Dana/Summit TC. Sometimes erroneously called a Bandit TC because they shipped so many of them.
It is fun to watch. strange to run with it so close to the quill.
As I recall(?) Kirk took over (with EMC) full operation of his TC. On the Iowa Kasugas, we left the original Dana/Summit TC control in charge, since it had been trouble-free. Except for having to replace the impact wrench a couple of times over the years, lol.
So we kept the original 5-wire interface.
I'm not sure about the status of ours; I do hope I don't have to write a ladder for it.
Impact wrench! now I get it. Ours has some hacked apart piece of DeWalt gear running the drawbar.
clearly not original equipment
Yes, we're using an electric Black & Decker, I think.
how much torque do those typically need?
When Dana/Summit designed the TC, they wanted to make it easy to interface to anything, so it uses a five wire control: carousel up/down/home, tool in/out. That's it. OK, I'm wrong, six wires. You get back a "done" signal (pulse) after each command.
good. I think ours works. that will save me some headache!
good. I think ours works. that will save me some headache!
oops. repeat. Does the drawbar ever stick?
madsci42: It's just an MTB40 toolholder, so it shouldn't take much more torque than a Bridgeport, or any drawbar. But it gets used (twice!) on every tool change, so it wears out over the years.
40 tapers shouldn't bind, i guess. I always have to knock on the top of my Bridgeport.
But there's no torque sensing, or slip clutch, just timer adjustments (how long it pounds on it). So torque is probably higher than needed to be sure it's in. A little hard on drawbars too, I think.
still, elegantly simple(is elegant the word I'm looking for?)
maybe Hacktastic is a better fit
i like it that it looks fixable
I've got an axis use question.
Are there other ways to jog and other preset speeds other than using the slider to set the speed?
I come from a Mach3 background and there are hot keys like ctl-direction to step jog and shift-direction to jog at max speed.
a good question. I often use the . and , to move the slider, but this is not different from moving the slider, rlly
All I've figured out on axis is to set the slider with the mouse and then jog with arrow keys and page up/down.
I bet there is a way to preset an increment and do an incremental jog.
, and . are slower and faster, respectively, but I have wondered if there isn't a way to make it jump to presets
There is an increment selector pull down (.1000, .0100, .0010, .0001, etc.), but I'm guessing that's not what you're after?
Is there a way to assign a hot key to the increment movement?
So you have something like ctl-arrowdown to jog axis_1 one increment?
Where's the pull down? I thought I went through the menus.
It should be on the upper left area of the AXIS display. Just below the X,Y,Z radio buttons.
Yes, I remember that when I first started with it a month back now.
So is there a way to assign configure it so that ctl-arrowdown would move .010 and alt-arrowdown would move .001?
I'm not sure, I don't know. But my first guess would be no, since one of the increment selections is "continuous". But I could be wrong.
BTW, did you ever get your velocity loop business sorted out?
WesBaker:you can use your number keys to feed overide speed,1=10%,5=50%
hmm no utsrelease.h in my 2.6.34 build
that solved it - it looks like emc cant get the version string from version.h according to what configure.in is trying to do
well rather configure not emc..

talk amongst yourselves
must be a compiler version thing
anyone know if i can make a pyvcp button to run a g-code command?
what's new in here?
I see 2.4.1
I got a new old Rotozip today
hey pfred i figured out my problem
i looked at configure.in to see what it was trying to find for the version string - it uses one of two files from the kernel
either utsrelease.h or version.h so i found that for some reason my 2.6.34 doesnt have utsrelease.h and for some reason the fallback line interpereting version.h wasnt working
so i looked at utsrelease.h from a previous kernel that worked and made one up and that solved it
til the next bug bites you
it did already lol
but i got over that too for the time being
so now finally i have a working emc2-241 , rtai3.8 and kernel 2.6.34
Linux spot 2.6.31-22-generic #60-Ubuntu SMP Thu May 27 00:22:23 UTC 2010 i686 GNU/Linux
part of my problem is probably that im using debian
this isn't my emc machine its a Karmic Koala
I may give debian another shot sometime in the future
- just on an old uniprocessor p4 box i wanted to get that version of rtai running to try in on an amd64 machine SMP to see if the dedicated core thing has an effect
ubuntu does seem a tad bloated to me
i get more and more frustrated with debian lately ... its all i have used for umm 11 years or so
yeah the bloat and incompatible upgrades are what are annoying me in debian - i figure if i went to ubuntu it wouldnt solve much tho
I've tried debian for more than 11 years there's always something about it that makes me format the drive
i have an old p2 dual processor machine, from 2000, its upgraded through every version of debian till a couple years ago
never had to format it
oh it is my decision I have high standards
i think i stopped at sarge with that machine
debian has never quite lived up to them in my estimation either
but I'm willing to give them another shot someday
to me lately they keep making insane changes - which keep creating way too much work - and lately lots of bloat with the gnome insanity
last time their package manager was broken and the way they had it there was no way my sound could have worked
was some kind of critical version mismatching going on with it
and that was on the stable release
for being current there have been some improvements with alternate package archives,
everyone kept bleating run unstable if I wanted to run unstable I'd do Windows
hehe yeah well i think about windows then i calm down and dont mind debian so much all of a sudden :-)
I loaded up suse 8.2 and ran it until that machine literally blew up
just went ot it one morning and it was dead
i was going to try that a few times but never got around to it
i heard suse was pretty tight
they have a crappy lack of an upgrade path
least that was what I ran up against
but yeah when it worked it was nice
it guess its hard to stay current - AND stay small AND stay stable... kind of conflicting variables
well small and stable arent at least but current definitely
how long have you been using Emc?
well I started my project back in the BDI days then things happened and I had to set it aside
and this winter i got back to working on things
I have my electronics done and am working on the mechanics now slowly
far as I've gotten with emc is stepperconf
and the sim
I feel when I get my machine going I'm going to have some configuring ahead of me
yeah never how one plans
but thats why I'm doing it just to do it
I like fiddling around with electronics and making machines so it sort of fits
i started in emc trying to make a dedicated box, minimum hardware and software so i never even tried to run axis or the other gui's
which kinda helped because i got used to configuring the files by hand which gives a good handle on it after a while...
well my emc box is dedicated
just a piece of junk i picked up at the dumps
or rather pieces
yeah same with my original emc box
I've run up against software step signal generation issues with it already
ones i don't fully understand
because if I lie about the microstepping I can get a lot higher rate out of it
like glitches or following errors?
than it'll give me if I'm honest
just it'll give me a much faster clock
which I don't understand maybe there is backend stuff that comes into play?
I don't think my hardware will go better than about 1.2 IP/M anyways
well most motor drivers let you choose from a range of microsteps so you have some freedom there - trade off is minimal
yeah I have to settle for 1/8th microstepping
on 1/16th I can only do max .8 IP/M
with a regular motor and drive thats probably as high (1/8) as you want to go anyway
1/16th is mighty smooth
but 1/8th isn't bad
really on my Y axis I made different drivers and they run half stepping
but with 400 step per rev motors so it sort of balances out
try gray code stepping
like in quadrature
I have a unique design in mind I am building
then you get double the rate from the software
if your making your own drivers its easy to translate the pins with a few gates
well at the voltage I'm running I can only go so fast anyways
made past tense
I'm running what i built for now
someday I may be in the mood to make different drivers
but not anytime too soon
really I'm happy to be ont othe mechanical aspect of the build now
is your axis using leadscrews ? or pinions?
lead screws 10 TPI acme
though I've seen some impressive belt and chain drive machines
my first frankenstein mini gantry was done with those
resolution doesn't seem to suffer too much unless you're carving matchsticks or something
like as it stands now my machine has a resolution of .00006 which is just silly
it won't hold within 100 of that I doubt
100 times that is
yeah with flex and vibration - not much can anyway
but thats just how it worked out
well I am going to be using some big steel
the X axis will be 3" heavyweight angles
because I have them laying around
I'm doing skate bearings and angles for linears
I've seen just about every CNC machine design out there
and mine isn't quite like any of them
most of them seem just poorly balanced to me
with the Z axis hanging off the side of the Y
just seems crappy to me
I'm going more of a mechmate style
from what little I've been able to see of it
my Y will lay down horizontal and the Z will go through the middle of it
and I'm going to have an elevated X too
like Z will go under the X
because it can go through the Y
thats how i made mine
x and y overhead
welded frames with machine mating parts where the precision matters
like here is a rough sketch i made of my Z axis and part of the Y : http://img408.imageshack.us/img408/7121/ztop3.png
I'll build my Z first fit Y to it then X to that
I'm sure most people start with their X then build their Z as an afterthought
but i gave it some thought it makes more sense to build Z first
the whole goal is to move a tool right?
I want my machine to take my Hitachi M12V if I want ot throw it onto it
its a pretty beefy router though
its no Dremel thats for sure
i tried to make mine as versatile as possible
I can see myself changing spindles depending on the job I am doing
[05:11:01] <madsci42> http://img710.imageshack.us/f/lt44.jpg/
you don't get flex in those rods?
my idea is to pivot Y 90 degrees and run between them
that way the tool is supported evenly between them
this is the head assembly; http://img256.imageshack.us/img256/6691/lt44headassy.jpg
actually i found them to be pretty rigid
i have a new version that uses split bushings with support structure
what are they about an inch in diameter?
exactly yeah - hardened class L alloy shafting
hmmm I'm surprised solid rod is so rigid
the trick is the ends are supported so they act like a cantilever
that machine is actually just a 3.5x4 foot span
i would not go more than 4 feet unsupported
oh you're saying that top frame is giving you tension?
top frame and corners
my initial idea was to make a box and roll on the top of it sort of this machine has similarities to my idea
so like in the ends i machined them slightly concave
and put a high tension bolt that pulls them flat up against the corner flats
which makes a surprising difference
but I'm just going to use such massive pieces of steel it'll be rigid on its own
3" heavyweight angle is some big stuff
i wouldnt put anything too massive on the head but for light routing, plasma, engraving, and drilling - all depending on material - it works great
yeah that is
but my Y will be 2" lightweight
because it'll be active
i get about 600 ipm out of it
what pitch screw?
keeping it under 400 for reliability tho
i made it so i could swap tool heads
I'm not in any great hurry
mine will just have a platform that accepts tools or jigs
yeah in hindsight i probably would have had an easier time going that route
but i wanted eventually to auto change tools
if I'm lucky i should get about 60 IP/M
long as I'm not cutting too much air it shouldn't be much of a factor
if your doing routing/engraving type stuff - i would think you dont need alot of speed anyway
plasma needs it with thin sheet in my case
I never push a router faster than 30 or so IP/M by hand I don't think
i want to cnc my knee mill
I've no use for a plasma cutter that I am aware of
and it just has the 5tpi ground screws - cant foot the bill for ballscrews so im thinking to just run with whats there till i can upgrade parts
I have a benchtop chinesem ill and again I don't see the utility of CNCing it for what i do with it
I've no need for strange pocket cut parts
well mine doesnt have power feed either - so just for that it would be nice :)
I slapped an X axis power feed onto mine
i would proably still do mostly manual stuff on it
its handy like when I indicate a vise
or do a fly cut
cranking at a particular feedrate gets old fast
but overall its not really all that useful really
yeah im kinda mixed about it
heh mine is one speed and to tell yo uthe truth its all I need
I keep saying I'm going to build a speed controller for it
wether I CNC it or not - i still have all the setup time to worry about and fixturing issues
but I have it pulleyed to one OK speed and its OK
its a gear reduction drive motor anyways
I got it from a machine shop I used to work in they tossed them out al lthe time
I have like 2 more on the shelf so to speak
we ran bridgeports with them but they were a bit under powered i guess
used market is great if one keeps an eye on it
well the way we beat the crap out of them
mine is an import, like a heavier (looking) version with the box ways - 3vs
thats why the boss was tossing one out a week
and most of the time it was just a hung brush or something
they're cheap I guess it wasn't worth any time for them to fool around
so you probably know more about my mill than i do hah
but you said it was a knee mill
no its a full size
I have an RF-32
vari speed head
ries_ is now known as ries
i should have got pulleyed head
its basically a drill press with limited milling capabilities
yeah a friend of mine has the rf45 style
if I'm really really careful I can mill with it
it seems great to me - his is older and has a beefier head than the ones i have seen lately
have you figured out the secret yet?
to these crappy chinese mills
its all in the way oil
it took me a while to figure out
when i got this machine it was with a lathe the mill was in good shape but i found some stuff in the lathe that bothered me
so i stripped both of them down comlpetely
but I'm using chainsaw bar oil on mine and its like a new machine
cleaned all the sand and junk out of them (there were spare parts in the bottom of the lathe carriage gearbox)
sort of sticks the ways together somewhat
heh yeah the sludge chinese think is grease
and i just used way lube since then
and proper oil in gear boxes and such
well try bar oil its the same stuff and a lot cheaper and easier to get
yeah i heard it sticks better
yup sticks like magic
like stays there
gives these machines a nice feel
all I know is I get less chatter and skipping and whatnot since I've been using it
I'd say it is a vast improvement over say like sae 30
it is my goto shop oil anymore
i was using some compressor oil i had for a while
and at $2 a quart from the big box store I always have a quart on hand
it was very good oil but when i switched to vactra i noticed the feel was different
I need it for my chainsaw anyways
but its just dynamite stuff
but the vactra doesnt really stay there at all
well get some bar lube if you don't like it you can always use it somewhere else
less than the compressor oil
yeah i mgiht give that a shot next time i am at the right store
I use it for everything oiling motor shafts you name it
wherever I thnk something needs a spot of oil
and if its too thick i brush some on then shoot it with PB Blaster
like if i have to oil pliers joints or something
but yeah bar oil is the stuff
and its non detergant so its not hydroscopic
thats good - wow i really think ill try that stuff - i have never actually used bar oil for anything
heres my machines http://img816.imageshack.us/img816/518/1002234.jpg
sticks like glue slides like butter
what is that little blue cylinder thing behind the head?
oh! hah took me a second to clue in to what you meant - yeah thats the motor
thats not a treadmill motor is it?
yeah it is
but it works great
when i first got the mill i didnt have 3phase
was it 3 phase or something?
3 phase is only great if you have it
now i have 3phase so i coudl put the original back on - but i made a speed controller that works nicely
and really I don't have all that much trouble reversing single phase anyways
so i stuck with it - seems to have as much power as the head can take anyway
sometimes too much power can lead to bad things
and short bearing life
if nothing else
with this i have a pretty good feel if im pushing it too much
I have to adjust my belt again it stretched in
its 2.5 hp which is enough
I use that link belt stuff
i hate the vari-pulleys tho
can that stuff handle load?
sure its a belt
it is as strong as a regular belt
i want to replace that first belt with soemthing that doesnt cause vibration
the motor is good but the belt causes some
thats what they say link belts do
my mill is such a chatterbox it is hard to tell
I think its is something in the stand i made for it
mine also gets it from the spindle somewhere
seemed sturdy enough at the time but I think I have a resonance issue going on
like the draw bar maybe - i never did figure it out
I know mine the grease ran out and they loosened up
I had to repack them and retighten them etc.
not sure - they seem tight - hold tolerances well etc
I was doing a lot of wood on and aroud mine and the dust sucked the bearings dry on me
i wanted to find a spare set decent quality ones
but when i can find a deal on them
[05:49:54] <pfred1> http://img26.imageshack.us/img26/1415/anvilspark.jpg
me beating on my mill
the truest anvil on the planet lol
with my gypsy power drive engaged
oh its like a mirror on top
carbide fly cut
I still have to grind the horn and polish it
yeah it is chilled cast iron I think
I was running 200 SFPM I think
can't remember i tried slower it didn't go as well
thats exactly like the one my friend has
its an RF-32
yeah its an overgrown drill press
that sort of mills
good enough for a hack in a garage like me
its an awesom drill press
i guess those cant be trammed easily?
is proably the only thing
not really no
I've messed around with it some and can't get it perfect
it leads on one side especially with a big fly cutter like that it drags and leads
is that a grinding setup of some sort on the right?
thats a carbide fly cutter
burning off the chips
theres another contraption there with pulleys
thats my power feed
oh in the back?
heh thats a lathe I made
sometimes i think is hould have got smaller equip
see if I can find a pic of that
but i didnt have much choice i guess
heck I'll just put up another easier than looking for it
seems I have 3 bits I have nfc what to use them for.. they kinda look like nails o.O
tip has 3 faces.. supposedly it's for engraving but I can't really see that work nicely unless if I have a floating hea
grind it like a d-bit maybe?
maybe they have off-center points
I plan on replacging the spindle I'm in the process of making a new pulley pattern to cast
[05:57:33] <pfred1> http://img341.imageshack.us/img341/2036/headstockh.jpg

hey if it works tho
Jymmm that is how I did it but I wanted it concentric
madsci42 well in order to tension the belt the lead would have flexed
i need to make a crude lathe for stuff thats too brutal to do on my real one
it took me a while but I got it done
set screws hold the bearings in the angle iron?
cap screws actually but sets would have worked
I drilled the holes with a holesaw on my mill
smart quick setup
i have done stuff like that for coil-winding jigs and such
first question is always 'whats handy... whats expendable"
yeah grabbed a piece of scrap cut it in half drilled it out put them steps on it with bandsaw drilled and tapped the sets
and i may even use them on my machine to hold the bearings
have to see how it all works out
least I'll make whatever I hold the bearings with in a similar fashion

madsci42: what emc version you're trying to build on what system?
i tried the release version and also one i got from the git repo
you should try: make clean && git clean -f && make
system is debian sid, 32 bit pentium 4 uniprocessor machine, against kernel 2.6.34 and rtai 3.8
so ignore above tip

yeah i have been through those - i have successfully compiled emc several times with past versions
and .. actually i also did a version of this one on the same machine - but it was with an older kernel 2.6.30.x and rtai371 - no problems there
duct tape perhaps fragalot? :-)
madsci42: can't help much
thanks very much for trying tho! :-) i appreciate it
whats the topic? =)
madsci42: error is saying that is no declaration of 'pci_find_device' in headers, so you must locate valid header with it

frallzor: compile rt + emc on debian sid
it does a similar error on every instance where the pci_find_device is called
i dont use any of the hardware that those drivers are built for so I was able to get around it just by putting null in place of the call
madsci42: balanced it on my chair xD
don't trust it enough to go off and mow my lawn meanwhile though
the reason i think it has something to do with my c version or kernel is because the same tarball built fine on the same system against a previous kernel a few hours prior - when the new kernel was installed I had to update the build tools
in order to build the kernel
madsci42: this driver is deprecated so maybe it's incompatible with newest kernels
could be - on other issue i noticed was configure.in wouldnt parse version.h correctly
my previous kernels all had utsrelease.h (if im remembering the name correctly) which is the first thing config checks
on git master hal_5i20 was removed already
if it doesnt find that it falls back to version .h i think - for some reason my 2.6.34 didnt have a utsrelease.h so i typed one up and was able to complete configure
it was doing it in several other drivers too tho
wherever - in the driver there was the call to pci_find_device to check if it was present i presume
im sort of mostly mentioning it incase someone here finds the info useful
i need to get on the mail archive one of these days
but it would be cool to learn if i did something wrong
It would be better that you mail to emc-devel list with those info, our emc kernel hackers are sleeping right now :)
this channel is cool tho
ive experimenting with emc for a around a year and a half on and off ill be using it for the long term so i figure worth getting more involved with the community
im more of an electronics person tho
cool to see what everyone is doing with it
madsci42: how good are your electronic engineering skills ? :P
i have been eating sleeping and breathing it since i was 11
could you design a voltage/current regulator for an oldtimer car that has a 6V field coil dynamo in it? :P
madsci42: I've builded around 20 machines with emc so I can tell it works fine :)
very likely frag - I'll have to brush up on field coil dynamo tno
madsci42: and how much would you charge for designing one?
yeah emc is great - rtai and linux - its a fantastic combo
I've tried a few times but keep failing at it
i have to learn to write drivers for emc tho - i need more input capabilities
you are just looking for something that outputs a given voltage with a current limit frag?
madsci42: it has to be regulated so it charges a 6V 84Ah lead acid battery
the previous system in it used mechanical PWM on the field coil
you ahve a diagram of the dynamo output?
or any data at all on it
would be helpful
yeah looking now
it's for a Trabant P601 xD
is it me or is internet search going to pot
seems like it was so much easier to find useful info 10 years ago
advertisements have ruined search results
do they have IGBT's in Belgium? :-}
I've got some diagrams (not too useful, too dumbened down) from books that I could scan in after my machine finishes engraving
well if your not in a hurry i can try and come up with something - i have to brush up on dynamos tho
it's not that urgent no :)
still have a lot of work to do on the body, respray etc :)
the reason I like it is the same reason I like taiwanese machines. they're extremely simple to work on
i guess they have a distributor in toronto
mechanical pwm - what a concept
it's just a rudimentary current coil that works on a relays :P
3-unit regulator from ye olde times
whenever i work with / on devices from ye olde times - i always get new ideas
i havent used IRC since my own old times - how do i give you my email on this thing
/msg fragalot blah or /query fragalot depending on your client
jthornton:hows the weather out there
going to be 95 today
sounds like down here in bama
what part of bama?
I used to live in Pascagoula MS and take the back roads to Mobile to visit friends... at least we had a gulf breeze there
I finally got my mill homing to index fri morning
I bet your glad
its amazing that it does all this on a parport
yes that is ... did you put anything on the wiki explaining what you did to get it to work?
* jthornton wonders what the difference is between memory timing of 5-5-5-15 and 5-5-5-12?

wow what a link
should i put it on the wiki,or start a thread on the forum?

have people no knowledge of tinyurl or qurl.org ?
I don't do blind urls, and blame the ppl that run the website.
blind urls? it saves bandwidth ;)
Not if it's a virus/malware.
not that I don't blame you, but if you click on a 'blind' url from a guy who does a single post with no leadup to his link AND don't have a virus scanner, it is your fault.
I always post qurl.org links.
[16:28:07] <Jymmm> http://sfbay.craigslist.org/sby/tls/1789327594.html
wow, all the details. most people just say 'red toolbox, used' :P
what a rip I just saw one at K-mart for $5.99 the other day
Well, maybe he needs the dollar
no it doesn't
it consumes more.
since you first have to load the 'blind' url, which then forwards you to the real url, creating more bandwidth than initially intended.
it just saves defective email clients
on gmail, you can have a 10 line url, and it still understands
OMFG CMON RLY?!
so if you change from MDI to the jog screen in emc
and hit zero axis
it stops the movement
and if you hit okay you lose your zero
okay everyone can chill out i fissit
Bah, can't decide if I want to keep or sell a wire label/shrink tube printer =(
quote of the day"Everything seems to work fine but.... I tried on windows xp the KCAM 4 but nothing... "
"I did the steps as in the manual of the EMC requires but nothing...seems that I do something wrong."
is that a question?
because it's kind of hard to recognize it as such, if so
not that I could see
cradek: need help with calibration not poping up
well time to wander out to the shop and finish setting up the Hardinge for some left hand threads
JPM_MILL: Servo Axis Calibration pops up for me on 8.04 Axis 2.4.1
[18:21:59] <JPM_MILL> http://pastebin.ca/1882370
JPM_MILL: pastebin your hal files
it was working about a month ago now its not
[18:24:56] <JPM_MILL> http://pastebin.ca/1882374
in case this was missed.. Proof that we are actually getting somewhere... http://www.youtube.com/watch?v=MucNO3Dij9o
JPM_MILL: you're runing from package or compiled source code ?
first time hydraulics has been up for a few years..
you can do small troubleshooting if have few minutes
goto console, type: sudo gedit /usr/bin/emccalib.tcl
ok gedit opened up with a blank file
JPM_MILL: sorry close it, give me few minutes
JPM_MILL: ok goto console, change to /usr dir, type 'locate emccalib.tcl'
[18:41:38] <JPM_MILL> http://pastebin.ca/1882384
sudo updatedb;locate emccalib.tcl
JPM_MILL: ok edit this file as superuser
put blank line after line 184
and put in that new line 'puts $tmpstring' (without quotes)
then save and run calibration again
and pastebin console output when it errors
[18:49:17] <JPM_MILL> http://pastebin.ca/1882389
$tmpstring not $tempstring
truetype tracer has some new features: http://timeguy.com/cradek/01276453959
cradek: What does "fill in the letters" do? Purely visual thing, or like v-carving?
Jymmm: you can see it in the screenshot - it does scanlines and then traces the outline
cradek: I thought TTT generated g-code?
[18:55:51] <JPM_MILL> http://pastebin.ca/1882391
Jymmm: yes it generates gcode (or dxf)
cradek: Ok, so the "FILL" is purely a visual thing (on screen), not remove that area like you would with V-carving?
it cuts out the center of the letters instead of just outlining them
Ok, v-carving. cool.
cradek: nice job
JPM_MILL: ok I've located where is bug
you must put space between " and . on line 235
of your hal file
it should work
that did it thanks very much
Micges: do you have time for another?
I'll try, go on
I belive i may have an encoder scalling issue. My setup is 2000 line encoder 3:1 reduction .200" per rev screw
when i move the axis 6" the axis dro reads 5.3"
i have a heidinhain dro comparing it to emc
Could i be missing counts?
I'm building a Probotix Fireball V90 CNC
Does anyone have any suggestions on some bits to use for woodwork, and sources for them?
JPM_MILL: when you moving 100mm forward and back in steps 10mm does pos error changes in any way?
does it raise proportionally to distance?
dont know i am just joging via mpg
so do small test: goto some pos in that axis, touch off, mark on machine current position of tool, start moving that axis for few minutes then goto zero on that axis and see if it is on place where you've done marks
it's the same in either direction. if that helps
Endeavour: it uses a dremel, so that's 1/8" shank stuff
Jymmm: Would you recommend any particular tools, though?
This is new to me. Not sure what I need.
Yes, I would recommend getting rid of the dremel spindle
Endeavour: You've never used a dremel before?
Micges: works out fine
Jymmm: Yes, I have. I have never milled anything before. :P
Micges: could it be i need more accuarcy on my scaling number the value i have is 133333.3
Endeavour: Ok, so what do you plan on doing?
JPM_MILL: if markers are on the same place after test then it seems that you have wrong scale on that axis
PCB and Wood milling.
Endeavour: I think cradek has a source for PCB tooling. And in that video, looks like they are using a rotobit, which is 1/8" shank. 1/4" shank gets you router bits which you can get almost anywhere.
micges: My scaling should be as follows 8000 * 3 * 5 2000 line encoder 3:1 reduction and 5TPI Correct?
Endeavour: I'd email and ask them what tooling they used in that video.
JPM_MILL: you have 8000 count per rev or 2000?
if 8000 then scale should be 120000
2000 line 8000 count. I fixed it I must of been drinking too much when i set the scale i set it to 120000 and all is fine
I must thank once again all the people that have spent time working on emc. this is a fine piece of software.
* fragalot stretches
^ that one
this sucks having only one computer that can reach the net :/
add network cables!
sux when you cannot find your box of adjustable spanners
Surely a box of them is overkill? Just one ought to be enough. (Arguably "none" is plenty)
hmm I collect them :)
I have network cables all over the place but my internet antenna is down so I'm on dialup :/
there are some good designs, and some truly awful
anyone ran an arc in 2.4.1 in G18 plane?
What is your opinion on the correct side to pull on?
and the patents for the adjustables make for entertaining reading
depends on design
Conventional sliding-jaw with worm type
jthornton: Not I.
heh wait till I finished my web site, I assume you mean the cresent/bahco form
and not the auto pattern
I think I have my coordinates and offset correct but I keep getting an error
jthornton: are you sure you have not been replaced by an alien?
what is an adjustable spanner?
but I agree - you only need two - one for inch bolts and one for metric
oh just an adjustable wrench?
what about left hand fasteners?
archivist: Aye, that type. I have always said you should push on the moving side, but I saw a Practical Mechanics article saying the opposite. They seemed concerned about the extra hand force on the worm, I am more concerned about the point of contact of the nut.
I have a two foot one I like ot use to straighten out bumpers and what not
jthornton: you can use the regular inch or metric crescent wrench for lefthand threads - you just flip it over and use your left hand
its sort of a wrecking bar with a vise on the end
well one way forces the worm and the other forces the loose jaw, you cant win
I have a really nice 12" bacho I use all the time
in the shipyard we were trained to pull the wrench with the fixed jaw away from you... then told we can use them on submarines and don't get caught with one on the sub
this is it: http://www.exetertoolshop.co.uk/images/catalog/BAH8069.jpg
they're not good for much except making knuckles bleed and ruining bolt heads
the number of designs is huge
my bahco grips better than any fixed wrench
the jaws angle inwards
cradek, I have some that cannot come loose on the nut
an adjustable turns two points on a nut - a real wrench turns six
even digital adjustables
there are hex adjustables
that sounds cool
I dont have examples yet just seen the patents
jthornton: arcs look fine to me - without your gcode and error message I can't guess what you are doing wrong
patents collected so far http://www.adjustable.archivist.info/patents/
I am looking at a milling machine on that eBay which has a swivelling table (swivels in C). I can't see what that gains you. (Other than Y and X not being at right angles). OK, thinking some more, as long as you are cutting on the Y it does achieve something.
archivist heh get the tools
pfred1, I have a "few"
archivist you should see this freaky wrench I picked up in a box lot guy was an organ tuner that had it
but out of all the adjustable wrenches i have I like my Bahco the best it never slips
I got one of these on ebay a week ago http://www.adjustable.archivist.info/patents/GB263633A.pdf
archivist you really are into this stuff
cradek: I must have my math wrong if you have no problem with arcs
I ran 3dtest.ngc
in lathe mode?
jthornton: no, my mind reading was not good enough to know you were on a lathe
archivist now I'm going to have to get my camera and take a pic of this one wrenc hI have for you
yea, G18 on axis lathe
pfred1, some I have taken pics of http://www.collection.archivist.info/searchv12.php?errlev=0&srcdata=title&searchv4page=1&searchstr=adjustable
jthornton: lathe_pawn.ngc in sim/lathe looks fine
ok, then it is my brain that is faulty :)
lathe_pawn.ngc takes too large a cut for my little starturn :)
I just tried it and get a radius to end of arc differs from radius to start in the lower right corner area
it loaded without error but did not run
tool radiuses ?
jthornton: I just turned my lathe off, or I could have checked master for you (I haven't got 2.4.1)
I'm running master on the Hardinge
jthornton: mdi M2 and G8 and reload lathe_pawn
and 2.4.1 on the sim
this gcode was from before diameter mode so there's no G8 in it, but there should be
running for me now
archivist sorry I was AFK
ok, then it is my calculations for the arc
do you know that when in diameter mode, the I offset is still in radius?
Just use R, that's what I do when IJ get too frustrating.
I kinda wondered about that and played with both diameter and radius
* jthornton tries harder the more frustrating it gets :)
jthornton: heh, the docs don't say it do they
no but they will LOL
as soon as I get my broadband back up and running
pfred1, good one
archivist I even use it sometimes
is it strange though or what?
pretty strange , but normal compared to some of those patents
archivist I got it in this whole box of junk I paid $5 for
archivist really the sheet metal shears i got in that box was the best things I found in there
but i do like this wrench too it has a place of honor in my garage
I borrowed that pic if you dont mind :)
oh I forgot i have to take a pic of the other side its the best part
its a Hoe of a wrench!
I think that is just so classic
thanks for the pics http://www.adjustable.archivist.info/images/
hey you're welcome I'm glad to find someone that appreciates bizarre tools
I am trawling patents and will probably come across the one for yours
yeah Feb 21 1922 it says on it right?
done 1931-1950 so far more years to do
you'll get there someday
often the ones I come across are broken due to abuse or poor design or both
this wrench works OK bit mouse trappish when cocked but other than that
you sort of have to open it up put it on whatever then close it
I can say 1922 was a vintage years for patents /me just doing that year
was a big year was it?
What's the status of EMC's Modbus support?
Is it suitable for monitoring things like limits?
Don't think so as its not realtime
