I was asking to myself, how the script sort the files in the dir ? by date-time stamp ?
there's few doc about.. just a small readme :\
i will try ..
ya know, I have some optical switches and wheels from a copy machine, I guess I could play around a bit.
with the midi port that is.
Jymmm: about ?
Jacky^ I was asking why noboy ever uses the game/midi port
I thought midi ran at 9600 baud
no idea.. but it don't seem to me so good
fast enough for keyboards but not real time control
I bought 3 isa parport for 10 euro ..
websys well, how fast is needed, and how slow is game port?
midi is a serial device - parports are much faster
USB is a different story
but we are talking a encoder here, how fast does it need to be?
USB is PITA (polling)
How fast do you want to run your machine
I'm serious... how fast does it need to be at a minimum?
depends on pulses/unit * max. velocity
would a 74LS374 be fast enough?
haven't worked with chips in a long time - sorry
I'm in the mindset of a old fashioned mouse here...
an 'encoder' seems fairly striaght forward from that perspective.
a mouse never generates a fraction of the pulses an NC machine would
on a good day.
mine can go up to 300cpi
some ive seen do 1200
Jacky^: Would appear that scan.py requires python-image plus a couple of other (as yet, unidentified) python libs
if a stepper as 200 steps (1/8 stepping) would 256 pules per rotation be enough?
how far does your machine move in 200 steps?
paul_c: yes, i've seen
5tpi ballscrews on 2:1 gears (I dont' know the math to calc it)
so 10tpi...you have to make 10 revs to move 1" how many puleses per rev?
i honestly dont know
ok a 8253 outputs to IRQ0 every 53mS (18.2 ticks per second)
cant find the timing of the midi port =(
well assume 100 pulses per rev... = 1000 puls/in at 300 ipm = 300K puls/min = 5K pulses/sec
time to go... Night all.
do we need to catch ALL 5k pulses?
which in serial terms means you need at least 56K baud
if you want to know where your machine is
well, we are not actually counting the pulses, just looking for changes in the pulse trian
if I understand it correctly
well I do know that a number of people are going toward dedicated cards to handle the IO since the parport isn't fast enough
but these are closer to comercial machines
well, encoders are serials devices by nature. is it 3/4 encoders being sent tothe parallel port that too slow?
3 or 4
could be - may be too many resources are tied up in processing so getting a card to handle it gives the higher reliability
or maybe most machien dont have a sound card/game port either
game port == bastard step child interface =)
this is interesting reading http://www.epanorama.net/documents/joystick/pc_joystick.html#introduction
seems the new standard interface is USB
well - have to call it a night - good luck with your research
Jymmm: it would be beautiful to see to work this 3D scanner :P
see what Jacky^?
the homebuild scanner working
you have/built a scanning probe yet?
no, i'm looking around
the url pasted by Paul_c is better i've found at the moment
[01:12:15] <Jymmm> http://www.indoor.flyer.co.uk/probe.htm
Jymmm: nice url :P
bedtime for me, have a fun
Jymmm: how's it going?
not too shabby, how bout yourself?
good, I think
I bought a Bridgeport this week
old, but with some goodies ;)
aut tool changer?
Centroid CNC control, 30 quick switch tooling, huge rotary table
if you dont mind.... $$??
plus 3 vises
at least I think so
riggers are moving it for me Wednesday morning
got to get a space cleared out in my garage
finally caught that one huh? lol
it's hard to throw stuff away.....
but I'm not throwing anything good away
try living in an apartment and say that!
me too =(
yea I've done apartments
did one 4 years ago. in transition between places
my stuff was stored everywhere. Father in laws place, work
all my stuff is here. Jsut some VERY creative storage methods
be right back

well, I need to figure out where to put it...I'll talk to you later
Jymmmm is now known as Jymmm
atleast u didnt say good morning this time :P
hello Yuga :)
i'm going to machine some piece :D
been reading all night.. and might actualy goto bed some time :)
i think i have changed my mind again
aaarrrggg... cnc headache
u can read about cnc for mounts, years ...
i should actualy just sit down and do... cause that way i arent alowed to change my mind :P
when you'll start action with cnc work you begin to pratically learn
if you get controllers and motors you could start to try something..
such setup your ini file properly
was going to use ballscrews... not going to no more... going to use rack and pinion

[Global Notice] Hi all. I'll be posting something later, but I wanted to mention this while people are still around for Friday.... if all goes well, we may do final testing of Hyperion 1.0RC* on the production freenode network on Monday morning around 9am UTC. Testing will last from about 30 minutes up through, well, permanent cutover, depending on how well it goes. 8)
[Global Notice] Please let us know if this presents any insurmountable difficulties; feel free to /msg me. Thanks.
\o/ looks like another bug nailed.
paul_c : how have you been?
Oh... Ranging from unbounded excitement through to really pissed.
well I hope I dont add to that frustration any
nah... I have the ultimate weapon to hand...
ah yeah user mode +b
gezr: So what have you been up to ?
lots and lots of work
more dreaming, no progress on the bike as of last time I was on, but Im almost finished building the privacy fence, ive been keeping up with the dev and user emails
I wish I could say that I have mastered C, and I am ready to upload fixes, but I cant
There is always documentation...
even simple little things like adding doxygen tags to the source code would be a great help....
I sorta started that before we went to working 10 hour days in this heat
we shipped some stuff to England a few months ago I think, maybe last month I cant remember now
trying a emc2 cvs up build now, I can hardly remember what to do
cd drc && ./configure && make
cd src && ./configure && make
oh, yeah, src :), yeah
on the make phase now, im thinking about moving that drive to my faster computer, the one its on is really old and slow
