Trying to configure my stepper ini. My mill has .2 inch lead on the xy screws.
1.8 deg steppers, 360/1.8=200, 200*5=1000 But setting input scale=1000 only gives 1/2 revolution on the motors.
g203v yes, I set to 10k and it looks like 5 rev but thought I'd ask
ok, 10000 - you wrote 1000
10k is cirrect - you forgot that the G203V is a 10microstep drive
Yeah I didn't quite get 2 rev at 4000, I plugged 1000 from my calc, but 10000 is what gave 5 rev
Ok, wasn't thinking of the microstepping since it was advertised automatic
yes, but it still does it ;)
I see, thank you SWPadnos
the general formula is microsteps * steps/rev * drive ratio * screw pitch
Thats a releif, step calculator looks like I can still get a decent rapid.

I hate it when the OS crashes at the "right moment"
JymmmEMC: you about?
[02:30:09] <Skullworks-PGAB> http://www.youtube.com/watch?v=eNqPTOb31S8
Ha.. del win.* /s
grrr if it weren't for mastercam...
You mean deltree C:\windows /y
This is too funny from one of the youtube sidebars
[02:44:11] <SkinnyPuppy34> http://www.youtube.com/watch?v=JahdnOQ9XCA
that one needed another 15 seconds...
JymmmEMC, can it wait a few days?
whatever it is you're pinging me about ;)
I could have wanted to see how your are doing, but sure, I guess so.
tell us how you are doing in 3 days :)
heh - if that's the case. I'm doing tired and stressed
SWPadnos: I got a bottle of cognac
I may make more tea
SWPadnos: But, you can answer the question I had in a few days.... I want to add a subnet /29 to a host, without using an alias (eth0:30), is there a way to do it?
so you want a /29 on the same interface as something other than a /29?
No, just the /29
But I've been told the only way to
add more than one ip address is to use aliases
'add' a subnet?
or you want to be able to access it?
ds2: a subnet in this sense ia a range of ip addresses
what's wrong with using an alias?
fenn: I don't want to add 40 or 50 aliases.
JymmmEMC: trying to figure out what you mean by add it... add it as in access it w/o burning an address on there or ???
are you trying to add a route, or a net?
"subnet /29 to a host" doesn't make sense to me
SWPadnos: a range of ip address so they all respond from the host
there are a bunch of ways
ok, and you said "add a /29" - that makes me think you already have a net on that interface
SWPadnos: I just got assigned a /29 range
ie, it has an address and netmask already
you can assume them to dummy interfaces
or you can apply the foreign listen patch and use the foreign listen interface; the patch was written for squid to do transparent proxying
SWPadnos: I just can't find the doc on how to add a range of ips to a host is all
SWPadnos: or even multiple non-concurrent subnet ranges
fingers in home position; resume typing
JymmmEMC: i've only ever seen it done with aliases; you can use lo:* if you dont want it tied to a particular ethernet card
for i in `seq 1 6` ; do ifconfig (however you add) 192.168.1.$i -netmask 255.255.255.248 ; done
SWPadnos: so basically , an alias per ip
I don't know if there's another way
or is there.
SWPadnos: ok, fair enough. I just thought that most admins are way too lazy to add one ip per line and would have a way to say like: add 10.0.0.1/24
they'd probably be lazy enough to automate the process, so it wouldn't matter how "hard" it is ;)
the important bit is 'up ip addr add dev $IFACE a.b.c.d/nm'
fenn: now THAT looks more like it
if you get the netmask right and use the broadcast address, does it respond for the entire range?
I think that specifies the netmask for that IP address, not that it should add all addresses in that range
fenn: I wouldn't know just yet.... I'm trying to configure the box then take it and plug it in at work
I don't think stations are supposed to respond to broadcast packets, except in special circumstances (like dhcp requests, for example)
SWPadnos: well, think like a virtual host with 255 ip address
with each ip bound to a virtual domain
I think I said that last one wrong =)
JymmmEMC: by virtual domain do you mean an apache virtual server with its own dns entry?
fenn: For example... to have https, it has to have it's own ip address per domain.
so the host has to respond to more-than-one ip address, in this case, a range of ip's like 100-127
the way we do it is with aliases in ifconfig.. it works for 8000+ websites, so meh
fenn: so if you have 8000 ip addresses, you are going to add one alias per ip address?
yep, dont type ifconfig without some kind of piped command
i was talking to a guy today who works with pico-amp current sensors
there's a special room he goes into to test them
i bet you could pick up all kinds of weird stuff with one of those
all kinds of small stuff - is the room small?
what are pico-amp current sensors used for? Neurons?
dunno, he works at a cyclotron
particle accelerator - probably part of some kind of a detector that looks for "events"
yeah thats what i was thinking
you can record the current along a bundle of wires and deduce the path of a particle from the shape of the signal
assuming its traveling fast
I worked with a professor on a scintilator detector that used fiber optics for look for cherenkov radiation given off in the fiber when particles pass through it. - similar -
I have some pistures on my flickr account - not that exciting -
i'm trying to figure out how to build neutron counters
uh, because :)
to develop a fusion reactor
seems the usual way is to catch the neutron with a nucleus that will become unstable - in real world terms this means a piece of indium(?) foil
then you can watch for the nucleus decaying
indium - thats expensive - and smooshy
soft - like lead -
oh, that's fine
it makes a good gasket in ultra high vaccum systems
hey this is always nice: Indium is a wonderful metal because unlike so many soft, silvery, low-melting-point metals it's neither dangerously reactive nor toxic.
why are you developing a fusion reactor again -
to launch tons of crap into orbit
and other stuff
have I talked to you before? - im not on here often - i just got Pidgin on my laptop and was trying out the irc chat functionality on the only chat room i have been to before -
i remember you were making some overlapping wave patterns using lost foam and bronze?
yeah that was me - you where doing the lost foam I think - I have never done that - how is emc doing - any new and cool projects -
there's tons of new stuff in 2.2 (or will be)
i just made a hexapod simulator: http://fenn.dyndns.org/pub/irc/hexapod_sim1.png
probably not too interesting unless you're making hexapods :)
the stepper driver now does double the step rate
* fenn is editing the changelog right now actually
lathe threading, rigid tapping, UVW axes, wait-for-input g-codes
03fenn 07TRUNK * 10emc2/debian/changelog: hope i did this right
I know what a hexapod is - but that picture is bizzare - is that something that would show live movement in AXIS
do you have a working machine?
hang on, will take a better pic
no, not yet
<insert lame excuse here>
<I was given a labatomy in my sleep by aliens>
ha - did you read accelerando?
huh. now i forgot how to run a program in tkemc
I read tha a couple months ago -
wholepair: yep, some of it was pretty good
matrioshka brains -
i'll let the machines figure that one out
i dont think a shell is orbitally possible, actually
the heavier side would tend to go towards the sun and then it would be closer so it would have more gravity pulling on it
you would have to balance it perfecly and then constantly nudge it back on center
unstable? works off the waste heat of the lower radius shells - good point probably defies some basic law of thermodynamics - that book somehow got me playing around with TiddlyWiki's - that was a waste of time
its a silly idea anyway, why not just gather helium 3 from the sun and burn it in your own fusion reactors
i think we'll be seeing a lot more of wiki's in the near future
when it filters down into the mainstream consciousness
splendid - get me a straw long enough to get to the sun and I will start sucking hellium 3 for your reactor - I gotta run fenn
have a nice day - or night - cant remember where you are -
oh right, screenshot: http://fenn.dyndns.org/pub/irc/hexapod_sim2.png
oh my - this is funny - http://fenn.dyndns.org/sketches/borg-cow.jpg
that looks much better - see ya
oh i see.. the "go" button is off the screen because there's 6 axes displayed
well, that's stupid
i would have figured it out but the window gets resized to match the screen resolution
so it is
sounds like late-nit hacking on drivers
yeah - you said it
actually, the driver writing is going fine. it's just that the FPGA config doesn't work now
after I made no changes to it
fenn: yay, the hexapod does get simulated
only issue I see is when I drag or rotate, the joints really dance around :)
fenn: you placed the tooltip based on world position, and the struts based on joints?
that would explain why it does the funky stuff it does..
(ideally in the simulation you only use the joints, and compute the platform position/orientation from that..)
maybe even colour it red based on constraints (if one of the joints isn't where it's supposed to be - wrong kins or such)
yay. another stupid problem solved
I think I've grown to dislike the Xilinx FPGA tools somewhat
at least it's not Labview
ant it's even possible that the Xilinx tools were part of the problem with LabView FPGA
though I think they added the incremental compilation stuff recently
