anyone know how to QUIT keystick by chance? hitting 'END' on the kybd doens't do anything
I'll try that in a sec. I thought I did and it didn't do anything, but I could be wrong.
ok max velocity is in units per second. Um, what units??? inch?
If you set units to 0.39....yadda... Yes.
ah, ok. Just wasn't sure what is related to what. but I'm getting there =)
I wanna see that ugly number removed..
oh wth... I'm just jogging and it says it has a following error.
What is your accel, max vel, & period set to
um Q doesn't work
period 0.000025 maxvel 1 maxacc 200
steps per unit (scale) ?
input scale 16000
set maxvel to 0.3 & accel to 10
maxacc of 200 is close to 1/2g ... pretty quick... leads to machine hopping
try pauls settings... much better to start with
it barely moves...!
I thought 200 was 200 ipm
1 second to move an inch?
it says in units
3 sec to maove an inch
0.3 is 3s to move 1 inch?
if moves are ok... try faster
will try 2 now
too bad I have to restart everything every time
2"/sec is getting pretty fast... 120"/min
yep. it CAN do 135IPM, so we'll see
with period=0.000025 and 16000 steps/inch, the MAX speed would be 1.25"/sec
most stepper driven screws will have trouble getting there for various reasons
bah! following error again
1/(period 2 scale) = ABS_MAX speed
1/(period x 2 x scale) = ABS_MAX speed
damn X keeps restarting.
running axis ?
how can I temp kill X?
no using keystick remotely
then kill X
ctrl alt backspace?
LawrenceG that just restarts it
paul_c is now known as me_me_me
me_me_me is now known as paul_c
ok, so what should I change to not get the following errors and increase speed?
I thought scale was 1" travel == 1" dro
reducing period will also get more speed
Let's run through a few calcs...
200 step motors ?
direct drive or geared ?
can you do 1/4 stepping ?
um. I think its full, half, 8th
OK... If you are not using X, reduce period to 0.000020, then try 1/2 stepping
mind you in mach2 I can get 100IPM
a genuine 100ipm ?
Yes, ruler and stopwatch
on a 366MHz celeron ?
no, XP laptop P4 2.8GHz
Let me ask this... what IS a follow error actually?
we can get as fast as that if you install BDI on the laptop.
My fujitsu laptop? Not a chance in hell =)
stepping constraints cannot step the motor fast enough to keep up with the planned trajectory
following error is the diff between commanded & actual position
ok, but somehow it's triggered by a calculation internally, correct?
but how is acutal position known to it?
Now.. If you really want to do a back to back comparison between EMC & Mach2/3/4, you really should use the same hardware for both.
otherwise it would be like comparing a Shelby Cobra with a Ford Escort
for shit and giggles, what should I increase PERIOD to since X isn't running?
then try 0.000010
good ruck charlie... but good to know what the limit is
heh... it didnt like a period of 10000 =)
hey Paul.. how is 4.24 testing?
attempting another upload
0.0000125 with keystick is fine on my 433MHz board
ok, I'm back
Would changing the para port from epp to something else help?
btw END quits keystick
paul_c ok, then I must have putty keybindings fubared
no point in changing parport mode - freqmod only knows standard mode
how are things?
having a few "problems" uploading the latest to a server.
a lot of the net has had some problems recently, lots of rorouting going on
hey, whats this ferror field?
set to 1.0
there are two ferror settings...
ferror is the max following error at full speed
min_ferror kicks in at low feed rates.
well, any other suggestions to try out?
I found a source for trucite B way material
south coast ?
up in wesconsion
for 1/32 thick stuff
Jymmm: Catch me over the weekend, and we can work through your ini
hmmm..... BUNCH of errors show up when starting keystick. (forgot to mention that)
paul_c ok, thanks.
once again, way past bed time.
the wifey missing ya huh?
gezr whats that?
its a special plastic that rides on the wear surfaces, its provides slip/stick prevention as well as improved wear resistance, and vibration dampening to any sliding surface
its only down fall is that its not so good at over 900"/min travel rates
higher speeds give it some problems for some reason
but on a box or v way machine it provides superior results compared to metal-metal contact
is well upset , bidded £171 on this and bid didnot get there in time had 33 seconds left :( http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=8214942970
oh my beautiful
[01:28:07] <gezr> http://cgi.ebay.co.uk/Myford-Super-7-Lathe_W0QQitemZ7541954296QQcategoryZ112399QQrdZ1QQcmdZViewItem
there is one like it a bit more money though
not in an aria i can get it transported from
I would love to own a myford lathe
I would cost me a ton of cash to get one shipped to the US though
dont thay sell them in the us ?
I think there is a place near me in North Little Rock that sells them but they are new and over 12,000$
i googled earlyer and before is swiched back to uk only sites and did another search it was showing companies in the us that sold s/h machines
one i looked at was $600 , it was the $ price that made me decide to re do the search for uk only
there was more , search was for "lathe for sale"
yeah, they are listed sometimes
but even in the uk from shops i would be looking at £400 +
Im going to rebuild what I have, then work on making one of my own design I guess
its almost cheap enough for me to have raw castings poured, however I have no idea how much mehenit(spelling) castings would cost
[01:46:58] <gezr> http://secure.enginemodels.com/cgi-bin/store/perlshop.cgi?action=enter&thispage=tools3.shtml&order_id=!ORDERID!
that place is 45 minutes away
ouch ,, expencive
I dont have that sort of cash
beautiful machines, just a bit expensive
oh check this stuff out
[01:50:35] <gezr> http://www.sherline.com/jmfJor03.htm
[01:52:38] <AchiestDragon> http://www.chesteruk.net
this place makes new ones and there price is reasonalble
dont know what the delevery would be to the us
they dont, uk delivery only
:) think i found something i do need more than a lathe
[01:58:19] <AchiestDragon> http://www.chesteruk.net/micromill.htm
£145 +£75 for the x/y
thats a small machine for sure
be sure to check out the mini mills pages before you get one
or google search for mini mill that is
that one looks a lot like a drill press, it may not have the bearings to do milling
well have also been thinking of a pillar drill with an x/y table
drill presses dont like to work as milling machines for very long
xy tables are mainly for repositioning for the next hole
for aluminium and plastic parts shouldent be a real problem
found another , 8"*2" bed 6"*3" cutting aria , no price , speeking of beds need to go find mine

Hi cradek. I'm still having difficulty with REALIZE.
03paul_c * 10emc2/src/emc/task/emctaskmain.cc: Bug fix to speed up program verify - Thanks Matt.
\o/ Finally got BDI-4.24 uploaded without any errors.
I'd appreciate it if cradek could start a privat chat with me.
Good work, Paul
cradek & jepler probably won't be up for another couple of hours.
must be close to midnight for you..
* anonimasu yawns
I finally got good earl grey :)
Hey Paul, do you have a spare NC file I could do some testing with? isd.ngc must be designed with "inches" in mind.
Still early, but SWMBO might pull me away from the screen
3D_Chips.ngc is metric
I'll give it a blast.
I do have some other large files, but they are mostly in legacy units
I was uner the impression that a "g" could be set in the file so that it would work on *any* setting
Should use G20 or G21 at the top of any ngc file, but most people don't
CR750: good morning
CR750: drop me an email. maybe you should send your drawing file so I can look at it.
CR750: or, we should try to talk in my late evening (0100-0200 UTC) which I think is mid-day for you
CR750: firstname.lastname@example.org or from my website http://timeguy.com
good morning America
Wanted words with you Steve...
Has Steve been a bad boy?
remeber those two isa cards I had off you ?
The single board computers?
the Viper830 ones...
duff batteries on both !
You can send them back for a full refund....8-)
wondered if you might say that...
oh, and leave the new memory installed when you do.....
not the sort of batteries the local rat shack stocks.

If I understand this correctly.... a following error is caused when EMC receives one too many wait states to drive the motors in a smooth operation?
like when you were a kid and played 'stop and go' ?
or 'red light / green light'
more like when you try to accelerate too fast..
like stomping hard on the gas pedal and the engine goes bleeuug
Well, I'm trying to understnad what actually is being triggered here.
kinda like putting boxes on a conveyer belt, one every 10 seconds. If someone doens't remove them at the same rate, you get a pile up.
or in this case a 'following error' ?
btw... I'm dling 424 right now.
* paul_c is uploading 4.25
should I stop?
I just start 60 seconds ago.
* Jymmm cancels dl
new change log?
what does 425 fix?
slow verify of ngc files, fixed a small(ish) bug with tcl/tk libs (I hope X)
new build of axis
ah, ok. cool
I wish admin cards weren't so expensive
or at least i386 hw could be run headless
but i386 will run headless...
I mean like SUN hw... straight thru to the serial port.
When I run TkEMC on XP and the connection is lost, it doesn't auto-recover.
no it wouldn't. the NML buffer read/writes would have timed out.
Shut down & restart tkemc..
Yeah, that's what I've been doing. Just whining
Just never happy about kludgy lost connections =)
If this laptop does have enough balls, I do have a desktop P3 733 (810 chipset) I could use, then just use the laptop as a console.
Hey paul_c, I dont see 425 being uploaded atm.
gimme a chance..
no way man.... NOW NOW NOW!!!
Jymmm: does your machine move?
anonimasu: It moves, but I'm trying to get it to 100IPM
is there any reaosn I can't make /boot and / part of the same partition?
One pig partition, or loads of small ones, the choice is yours.
ok, I might setup a dual boot option instead then. Just running out of partitions =)
m$, /, swap.
/boot, /, /vae, & swap
Paul (or whomever controls such things), thanks for causing the IRC status channel to issue pings, my logging sessions no longer drop due to lack of traffic.
/vae ? and I wanted to place /boot and / on the same partitions is what I was asking
Jymmm: how many pulses per "
um 2 pulses per inch?!
that sounds huge
I tried 200IPM (2), but got following errors.
or well that is rather huge..
what kind of accuracy are you expecting on your parts?
I'll deal with accuracy later. Right now I'm just trying to get the speed up. I can get 1235IPM under MAch2
isnt mach2 hardware generated pulses..
if you have 2 pulses per " you will be able to go as fast as you like
but well, you wont be able to do any precision work..
I'm not sure what you mean by pulses per inch. I dont see that setting in the ini.
ok, yeah, it's 2 iirc booting now
you wont be able to machine stuff with detail under 0.5"
input scale is set at 16000 0
max_velocity was/is set at 1.0
Jymmm: dont expect to be able to get to that kind of speeds..
that's lots of pulses per inch..
I cant remember where I hit the limit
but I wouldnt expect to be able to push out that manu pulses.
Well isn't the 16000 the value needed so that 1" on the DRO is 1" actual travel?
but for 100ipm
you will be pushing out (16000*100)/60
pulses per sec
ok.... if I change scale to 4000, what will happen to the dro/trvael stuff?
are you just changing it randomly?
well 4000 pulses will equal one unit..
sqrt of 16000 == 4000
why do you sqrt it?
just scaling it back.
yeah, well you could do that..4
what is the purpose of output scale?
I think it was for adc gain..
but as I've never used it I have no clue
ok if I change input to 4000, when I say jog 1", actual travel is only going to be 0.25" or will it be 4" ?
if you want more speed you will have to change your scaling at the drives..
full, half, 8th
or get a USC is what your saying.
ok... lets back the hell up for a moment....
In perfect conditions, what is the fastest pulse train I can get out of a serial port no matter the OS/application?
paul_c: are you there?
he's at dinner
I'm just trying to understand it all =)
I cranked up ok
I cranked up the cycletimes to get the max speed out of it..
but well, ended up half killing the ui
and gave me that tcl/tk/pthreads bug
cracnked what up?
I thought your USC board was suppose to resolve such things?
but I didnt have the USC before
I thought you said you just cranked it up... like within the last few minutes?
* anonimasu sighs I cant find my cd case
I can't miss mine.... it weights a ton
atm... uninstalling yahoo 7 and reinstalling yahoo 6
but, had to find yahoo 6 first, sigh.
I am drawing some
They nag you to upgrade, so I upgraded to get rid of the nag screen, but at idle it's taking up 35MB.
I could care less about their voice features.
I'm trying to figure out what to do now that the laptop isn't fast enough for 100 IPM

Manhattan is ... well, think of a dirty version of london, with more smells
so Mr Dragon, built your framework yet?
does it work?
give me a min and i'll upload picture to website
mmm, some nice 25A solid state 3 pahse relays turned from ebay
need bigger steppers ,, can move the y (with no load ) but the z no way
going to get the Llllanelli man to sell you some?

[22:24:12] <AchiestDragon> http://www.whipy.demon.co.uk/cncz4.jpg
youve been busy
can I make one suggestion?
got the x feed to sort , and a bit of finishing breaceing
if you can,
lower the Y axis rails to the very minimum you need
like, 2" not 12"
that will pay big dividends
k , its easy to change , have been thinking of re doing the z axis also
if the top Y rails were spaced as they are now
and the top one was where the bottom one is now ...
I should find you the pictures of the one I built ...
[22:29:36] <robin_sz> http://www.quacky.co.uk/~robin/cnc2.htm
and the stuff I made on it ....
[22:31:38] <robin_sz> http://www.quacky.co.uk/~robin/woodcarve_old/
anonimasu: yes, I kmow ... seen it before ..
anonimasu: but Mr Dragon hadnt
actually, I can show you what it makes now ...
* anonimasu slaps robin_sz
silly rabbit.. :D it's not your stuff I am yawning at
how's life going?
I am starting to get tired, I've just had 6 hours of sleep in the afternoon :D
I just flew overnight from NYC
spent a day in Geneva
flew to Luton
and then drove
all on no sleep
[22:36:13] <robin_sz> http://www.hps-tr.com/images/ultraStocks/fr703.jpg
see that handgrip ...
ah, that was the competition guns you were talking about before..
the router makes the handgrips, in several flavours
s,m,l left and right handed
plus a more "ergonomic" one
do you do custom grips
althoug we might fiddle a bit mroe in Rhino
we made wooden models and had them 3d scanned
I was thinking about digitizing from imprints..
cost a fortune
yeah, I can imagine
that'd rock :D
we thought about some sort of grip with a plastic bag full of epoxy ...
yeah that would be as neat
mix it up, squeezy wheezy
but it needs to *look* good ..
that stock 9without barrel and trigger) is errm .. not cheap :)
what you could do is a bag , get them to hold it as though it was a grip , fill it with the foam filler spray , then you got a patern to work from
yeah, but .. that mean s they have to come to be fittted etc
becomes a pain in the tits
ends up taking as long to do a custom grip as an entire stock ...
so a reallistic price would be another �1200 I guess
robin_sz: well, if I were shopping for the best stuff traveling a bit wouldnt matter..
it's not like thoose are your ordinary no brand guns :)
we're hping to do small, medium large
and 3 shapes
and if thay where that interested the price would not eather
* anonimasu nods
and half way between the two
in left and right hand variants
but a moldable one has been thought about
no brand guns? is that like no serial number guns?
<anonimasu> it's not like thoose are your ordinary no brand guns :)
* anonimasu sighs
oh these are a branded gun
[22:46:40] <robin_sz> http://www.hps-tr.com/ultraStocks.htm
well, not ordinary guns..
yeah, pretty specialist I guess
with barrel and action and sights .. close to 4K I guess
oh foooy.... I want no serial num guns.... like the old winchesters.
Hey Jymmm I was in NYC yesterday .. did you wave?
Jymmm: you can have no serial num guns elsewhere..
like in NYC ;)
anonimasu these are legal no S/N guns =)
Jymmm: or "old crap" as I call them
why would you want thoose guns?
or well maybe because they are collector items..(if they are)
there is a vintage rifle society
they try and hit barn doors with them
I have a 1867 (iirc)
interesting things .. that they survive that long
many go crystalline in the barel and explode when fired
the metal chnages
over a very long time
* Jymmm hands it to robin_sz.... here you fire it
I like the modern rifles more :)
famous Finnish rifle maker
yeah looked it up
never shot with one
found thease on ebay any good ?? http://cgi.ebay.co.uk/Superior-Stepper-Motor-type-42-series_W0QQitemZ7542752374QQcategoryZ26209QQrdZ1QQcmdZViewItem
robin_sz: I've got the usc pushing my machine along nicely now
AchiestDragon: probably a bit big for your machine to be honest
tonka! the famous yellow toy truck manufacturer!
probably off an old bridgeport mill
anonimasu: nice ... smooth is it?
AchiestDragon: and, cannot be driven off your drives either
yes know about the driver's not beeing up to it
AchiestDragon: �40 is quite expensive for a very old motor I think
and 11.50 postage each :(
well, they re HUGE
as in HUGE
say, 5" diameter, 12" long
have not checked the size yet
maybe 4" dia
5" dia looks about right given that the cable gland hole should be about 7/8"
think thay would pull the machine apart if it hit the end stops
well theres this http://cgi.ebay.co.uk/Stepper-motors-driver-CNC-mill-machine-lathe-workshop_W0QQitemZ7542364521QQcategoryZ12584QQrdZ1QQcmdZViewItem
but only 2 unknown steppers with it
given the connector shell style i would say its a late 80's unit but other than that , the manufactures website dosent even have a search so no more info
sahouldent be a problem modifying it , use the same psu , and strip back all the unneeded electronics so i can jsut give it step and dir pulses
maybe even fit a new trasformer for 22v ,, anyway emailed him asking if theres a part number or info on the steppers , if thay look good then ok
22v = 220v
you're alive A-L-P-H-A?
ty for tip about reducing hight of y axis , just been mesuring will shorten it by 12" that also leaves me enough unistrut to make 4 6" legs so dont have to buy antoher 3M lenth , and will mod the z axis to match
btw is the live cd download for emc working correctly yet
:( still says download size is 194Mb not 465Mb so guess not
