anybody here tonight?
I got my vise today
* anonimasu slaps turbocnc
I've been to the bank today
I made my final decision, never turbocnc ever again.
I ran a roughing toolpath for the prototype I am going to make..
* alex_joni digs in ssl stuff ;)
err simulated it..
it'd take 57 minutes..
due to the lack of motion planner..
and any blending at all..
that doesn't sound like a hard decision to make
let's see, closed source, windows, no motion planner
OR: open source, linux, good motion planner
it's semi closed..
cradek: I just need somone to help me set up my axis:es..
what's wrong with them?
oh, I cant seem to understand how to configure them..
or well my units..
yeah, it's not a hard decision to make, but since there's no docs on setting emc2 up it's a bit harder..
I got a machine vise today..
anonimasu: are you trying to use metric or inches?
you should probably ask jmk for help if you're trying to use emc2
yeah I won't be any help with that then
I do have a working setup in inches
you set up "UNITS=1" to use metric then you set up the length in the core_stepper.hal isnt that right?
I think all the parameters in hal are in steps, not units
the units are only relevant in the ini file
steps per unit..
I should give this another shot in a bit
just going to re-calc my steps..
cradek: may I trouble you with a question?
do you have any deb experience?
* alex_joni installed sarge
and is fighting with an imapd
no, but I have lots of other unix experience
I wonder what imapd I should run
I have a bit of dev experience
courier imap.. works great
you should run whatever supports mbx format mailboxes
courier does that..
if you have big mail folders mbx works much better than mbox
* alex_joni apt-get installed courier-imap
I run it at work..
an0n: do I need special incantations for courier-ssl certs?
you just generate them..
you have two files in your courier imap etc dir..
where you set up your pop3 and imapd ssl certs..
where is that?
don't I need to apt-get courier-ssl ?
it should be default..
atleast in any sane dist :)
I just I installed it manually so I am unsure..
me too ;)
but it should be there
check the etc dir for configs
doesn't work :(
what does it tell you?
IMAP connection broken (server response)
that's really weird
an0n: how do I see what packages are installed?
dselect something something?
* anonimasu nods
going to move my emc comp down to the basement so I can play with some settings
I didnt know how to do that :)
ask away for help
yeah I will probably ;)
websys: and to see files for a certain package?
I wonder if uw-imapd creates a /etc/initd/imapd script or not (can't seem to find it)
Hmmm - have to dig for that one
dpkg -c DEBFILE
alex_joni: surely imapd is run by inetd
cradek: yes it is
alex_joni: BTW your deb files are cached in /var/cache/apt/archives
found them already.. but thx
hm, I am trying this in a sec..
hopefully I wont get that joint following error anymore
Joint following error..
an0n: mail me the config
or paste it somewhere
I changed the stepgen.0.position-scale to 320 for all axis:es
and the LINEAR_UNITS=1 in the emc.ini and UNITS=1 for each axis..
if you wait I'll uppload the complete one..
[16:23:27] <anonimasu> http://18.104.22.168/an0n/emc.ini
what error are you getting?
try increasing MIN_FERROR
what's a usual value for that?
right now min_ferror is = 0.002 mm ???
make it 1 mm
or higher to see if it works
trying that first
which axis does ferror?
all of them?
or only Y,Z
0.01 mm ???
increase it a bit
also min_limit and max_limit are wrong
I don't think you want to travel 4mm ;)
it works great with 0.01
I think the limit was lower then the size of each step
it was :9
* alex_joni doesn't dare to disagree :))
ok.. so it works now?
I need a USB fd drive..
going to try out running from the cam program in a bit and try milling somthing
use axis ;)
hm, the interface?
the GREAT interface ;)
* alex_joni hates imapd !!!!!!!!!!!!!!!
I think I'll use this one for a bit.. :I)
glad to hear it works an0n
* alex_joni goes home
I wanna see /win 12
robin - saw your disc. about CAD on Sun. - did you try Synergy?
no, I have LOTS of cad
or was it a different robin_z?
its CAM I lack
no that was me
Synergy has the CAM included
is it 3D?
hmm ... I'll have a look
we used to do plasma/flame cutter stuff so it's in there too
will it run on 'doze?
and it's nearly free :)
bith Linux and Doze
non-free is fine, as long as it works :)
sheetcam is my current plaything
well it does most of what you were talking about
[19:38:55] <robin_sz> http://www.sheetcam.com
I'm just trying to persuade the author to modify it a bit ;)
You can modify our stuff as much as you want
why do you hide it so well ;)
but it's on the BDI now
heh, right loooking now
you know my interest I presume?
only prob is I don't have an install prog. for people to download the Doze version
I make plasma cutters ( or try to)
but I can give you a zip file
if you can unzip it the right place
how big is the .zip?
(incoming mail is limited to 10mb)
ummmm - have to remake it - right now it's 58 meg - can you use ftp?
eep. thats quite big
yeah I can ftp stuff
I think I could get it down to 40 or 20 if I remove the solid modeler
let me just check it will be able to do what I need, you can answer questions on it here ok?
want to go to a private chat?
whatever you are happier with
how's the mill running?
alex_joni: I've just been testing it out on the bench..
I'll mill the plastic part tomorrow morning
I am just playing with getting the accel... and max velocity high enough
nice to hear that
I like the speed of it loads..
I might try axis in a bit..
I have a working post for visualmill now also
hm, but well, it still seems like my feeds are a bit slow..
websys: still about?
what is max_velocity in units?
I just read through the logs about synergy ;)
an0n: the max speed you want to be able to run
websys: could I try it too?
an0n: well then 1000 is the value you need
and the max_accel
is that in seconds?
and the first is units/sec
but.. you know the rule:
code a little, test a little
with emc it's : tweak a little, test a little ;)
but it's better to know what you are tweaking
tweaking variables of the type "thingamabob" dosent quite help ;)
like max_speed ?
yeah, if it's meters/s or units/s
everything is in units
that's why you can state the UNITS
heh might be a little bit fast :)
might be why it ferrors ;)
what would a sensible accel be?
I ran mine at 40000hz/s at the turbocnc..
an0n: what was that imapd again?
ah works now..
I moved the HALFILEMAX
to HALFILE <cr> MAX
what's wrong with "alias ll 'ls -al'"
alias ll='ls -al'
yeah.. just figured it out
the first one is for sh
not bash ;)
* anonimasu hugs zsh
it's a nice shell :)
* alex_joni is a bash fan
when I started using bash.. I was born again ;)
I am a tab abuser..
I wish there was a good code editor with tab completions
for variables and stuff.
* alex_joni so agrees
it'd be so quick to code with
I think mc is nice as an editor
* anonimasu makes a mental note on that
better than vi & family ;)
anything but vi..
vim is pretty nice though
but vi is awky
how about emacs?
* anonimasu cant touch emacs with a stick
hm this works nice when backplotting..
but it still seems slow...
I am machining plastic... :/
I just had a thought...
hitting tab completes stuff.. right?
dont you use that in bash?
I think sometimes it would be usefull to uncomplete (e.g. wrong choice)
smthg like an undo
oh, you tab multiple times...
and it cycles between what you want..
and if you write more char's it narrows it down..
nah.. that would be annoying ;)
oh it's how it works in zsh/bash :)
in bash I know
but that's not what I mean
zsh shows a list of possibilities..
yeah that's a bit annoying
say I was looking for INSTALL
but I was somewhere else with my mind, and I typed R-tab
it quickly expanded to RELEASES
but I need ot go back, and expand I
now I need to delete all the letter tab expanded
alt + backspace ;)
removes the whole previous word..
although somthing with tab would be easier to remember
definately not alt-tab ;)
or ctrl tab would be nice
read a few posts sooner ;)
sorry.. mind is wandering around
playing with emc
trying to get this toolpath to go fast..
still milling the o in the middle feels very slow..
ah F500 helps ;)
what motion planner does emc2 use by default?
I think the non-segmot
hm, ah, that might be why it's jerky..
does segmot work ?
yes it does
and how do you enable it..
you need to use another executable for task
do you have to compile it separately or does it compile with the rest+
it should compile
but if it doesn't .. you need to
hm, it's the TASK= you change right?
sorry for asking lots of stuff :)
you change EMCMOT=, not TASK
an0n: yup on what cradek said
what do I change it to?
it's not there..
cradek: is there segmod for emc2?
alex_joni: not that I've touched
don't seem to see one
isnt les running emc2..
oh you are using emc2?
or is that emc1?..
no, les has servos
les is running emc1 with servos iirc
emc2 is no use to him
I wonder if I can get emc1 to compile on the box..
hm emc runs on the box..
or well.. I can see the logo..
but nothing more :)
on what box?
the same as I run emc2 on..
did you compile?
emc2. yes but not emc1
well.. start compiling emc1 then ;)
* anonimasu sighs
if you're not happy with emc2
lol, 50 minutes for making a small part dosent make me happy
don't think that's a seg-related stuff
more a speed issue
cradek: am I right?
500mm/min should be pretty fast..
the part is 6x6cm
an0n: if your accel is slow... you can't go fast on short moves
alex_joni: what's the question?
does segmod improve the speed?
wouldnt blending the lines instead of stopping and changing direction.. help with that..
depends greatly on the program
if you have mixed arcs and lines, it's a big help
on any program the motion is less jerky
* alex_joni thinks anonimasu needs more work on his setup
if your machine is pretty light so the jerkiness doesn't bother it, the old planner is just fine
I'd change the accel values too
oh, it dosent matter that much..
but the time to mill the part is supposed to be a couple of minutes..
accel matters very mouch
if you have short moves
if it takes 50 minutes I could machine it in stainless instead..
accel matters a lot more than speed
you can go up to speed.. but only following a max_accel
if the max_accel is low, you won't reach the max_speed (or only very late)
try increasing it till it starts loosing steps, then decrease it a bit
* anonimasu thought lookahead would make a big difference in making the program continous..
[21:05:52] <robin_sz> http://www.badgerbadgerbadger.com/
# badgery goodness
anonimasu: there is lookahead in the old planner - it's just not very far ahead
you cant have too many badgers
anonimasu: I bet it will work fine for your machine
max accel at 100 now..
coo thats slow
robin_sz: give me a value to use I am unsure on how fast machines are supposed to go
I think I have mine at 100 in/s^2
let me check
dunno .. my plasmas run 1200, I know my laser runs 8000mm/s^2
try 1000 an0n
looks alot better..
you'd love my big laser ... 0.8g accel and 84m/minute rapids
yeah mine is 128 in/s^2 > 3000 mm/s^2
an0n: like I said, keep increasing it
till it starts to loose steps (you'll surely notice that)
then decrease it some
or until it seems "too violent"
you can set the g340's too (PID-wise)
I wouldnt notice it..
my plasmas will run higher accel, but I keep it at 0.1g to make em smoothhhhhhh
but I need to grab the osciloscope and measure it..
an0n: increase it till you see the reset going up on the g340's
tell us what value that would be
light machine + lots of gearings = slow machine but heaps of torque.. it's like 250khz max into the geckos..
well.. then.. keep krankin it up ;)
but depending on the dynamics of the machine.. :)
cradek: what's the default you run at?
25 in/min 128 in/sec^2
my steppers will skip at 30ipm but have lots of torque left at 25ipm
how do you calc that to mm?
% units 25in mm
2.5cm = 1"
there are 25.4 mm in an inch
2.5cm != 1"
oh this is emc2 isn't it
maybe I shouldnt have kept feed override at 300%
then you probably need to dink with the hal settings
I think it should be fast enough now..
nope gives following errors at 1000mm/min
an0n: during run? or during accel?
during during accel I think..
I might have exceeded maxaccel..
in the core_stepper
try increasing that
is there a way to reinstall packages on debian?
that's in steps/sec^2
make it a little higher than the ini's accel
changed 150000 to 250000
it should be plenty..
alex_joni: only thing I know is apt-get remove <foo>; apt-get install <foo>
now lets see how it does the circle.. again..
ooh, lucky me .. as usual an inbox full of viagra spam
how about CIALIS?
I mean do they really see "stay up for 48hrs +" as an advantage??
you'ld beat it to death with a stick after 24hrs im sure
alex_joni: hey, wanna rolex?
does anyone want to see that part I that I am trying to mill..
robin: nah.. got a few
an0n: yes, if it makes you happe :P
alex_joni: oh, I dont have to show it..
alex_joni: want to be introduced to a son of a former Nigerian king, he has a money problem he needs help with
actually, I was browsing 419eater.com yesterday, most amusing ;)
robin: let me guess... he needs to take them out of the country
an0n: show it
[21:28:50] <anonimasu> http://www.bojn.net/~an0n/part01.JPG
alex_joni: seen 419eater? they persuade nigerian scammers to take photos of them doing stupid things in order to prove they mean business ...
robin_sz has changed the topic to: Welcome to the Enhanced Machine Control forum | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT3d part
ChanServ has changed the topic to: Welcome to the Enhanced Machine Control forum | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT
ooh 3d part
it's making the circle that takes too long time..
maybe I should change how I machine it..
* alex_joni goes to bed
would anybody know what might be causing
well, i'v got this problem where one axis is skipping steps, but only one axis and only in one direction
and its been happening with 3 installments of bdi, live-rc46, 4.08, and 4.14, but works with turbocnc
which leads me believe its not hardware
Intel or AMD processor?
its a pentium 2
there was a prob with bdi and amd
hmm, is there a way to make emc see x as y, and vice versa?
theres a gcode to translaet axes .. if I could remember it
im guessing it would have to be lower level than that to affect this, i was thinking, changing the parport pins x uses, is there a way to do that?
I have no idea about how to do that in emc1 sorry
how stable is emc2?
I havent tried it yet
just got my machine set up tonight
but it seems to work nicely atelats
I'll be testing it tomorrow morning
I may have to try that if I cant get anything going here
