Skullworks-PGAB: what kind of computer is that?
ok so i will use z insted for for my belt axis
can i set A Axis as Linear?
JMK - having read that - I knew to bump the system mem to 512 before attempting the live CD - and it worked fast an flawless
you can set ANGULAR and LINEAR units the same, but if you use G20/G21 it will not change the units of A
loaded box #2 last night
yep, 512 is the magic number
but I'm assuming that the older boxes are memory limited
ok, no problem i will use only mm
one interesting thing to think about for the low-resource problem:
xubuntu can use ubuntu packages
so, you can use the same RT kernel package that we are using
(I think - I'm not sure how the latest xubuntu works - when I did it, you installed the server (no GUI) version of dapper, then install some packages that give you the lightweight GUI and window manager that makes it xubuntu
have not messed with kernals in ubuntu - but built about 60 compiles in gentoo until I had that box tweaked
well, the biggest part of a puppy or damn small or any other EMC capable distro will be making the RT kernel
if you can reuse the existing RT kernel that seems like a win to me
jmkasunich: about the new driver 5i20 step/dir is it ready for use in trunk?
i think you can use .deb's in DSL, maybe not for the live cd though
danielbr: I've been very slow on that work
ok, so i will use a USC

hmm :) runs at 120 ipm just fine.. The input scale of the default ini justhappens to be the exact scale I needed.. Odd 4000
cradek, you are great!
all you developers, thanks
Arn't they though ")
thanks also to jepler for image in pyvcp
and when is ready for use with animated gifs I can draw some new leds and spin buttons in xara
replacing that canvas widgets
cradek with something like this is possible do that bargraf that change color above 90%
i also can port axis interface to GTK with glade but i can not do the pytgtk work because I don\t know python
if you think is a valid work i can do that
it is pretty easy to stop at 120ipm.. I don't think it is a problem
it could go faster - and it is smooth
03cradek 07TRUNK * 10emc2/debian/changelog: this is probably not everything, but much better
skunkworks: what speed on your computer?
I think 1ghz
what are the specs?
yes - it is this http://www.electronicsam.com/images/engraver/engraver.JPG
they are only 1.5a steppers
are you running them at?
home built PS?
no - actually have a parker 3a 75v power supply :) /compumotor - whatever
ebay is great

alex_joni: (I knew you were awake at this time =)
Jymmm: 4 hours already up
i have a problem making emc
anyone heards of http://www.proskit.com/
I am personally very surprised that you can start the spindle turning when you are in a state other than "machine on".
I thought that was fixed a while back..
alex_joni: I ran just one coil on the 6 wire steppers.. Seems to run ok.. the thing was rated at 120ipm and it does that no problem.
it just happened that the 4000 input scale was exactly what it was. must be 4 threads per inch. (1000 steps per rev)
told it to move 10 inches and it moved exactly 10 inches ;)
it is pretty easy to stop at that speed though - not that you would be cutting at that speed
jepler how fast do you want the probe to run
archivist: do you prefer to talk here instead of on ##electronics?

the printer port on the computer I am using will drive the optos in the oem650's directly.
argh. looks like mozilla restart time. brb
I suppose so
I think maybe my internet connection is flaky. I have DSL on line 2, and I get static on the voice part, so I imagine the DSL part is affected as well
I would guess - lots of rain?
we are getting by with no hardline so far.. Cell service isn't the greatest at the house though but we are getting by
you either have to call from the porch or the second floor.
it should get better though..
we had no rain for the last week or two (except today), but the problem has been there the whole time
the only support I have had good luck with is our charter cable internet.. Being a business here they actually try to help.
we just got an ad for Comcast 6 Mbps service ($1999/mo for 6 months!)
err - $19.99
silly decimal point
that is fast
they have 8 Mbps as well
I was happy to get 1Mbps here
(at home I should say)
I think we are 3mbps here
and they're all "burstable" - they give you something like 12-20 Mb for the first few hundred k or few megs of a download, then throttle it back
I am content with 1.5mbps down, but I sure wouldn't mind greater outgoing bandwidth than 384kbps
oh - it says right here - the first 10 MB if you have 6Mb service, and the first 20 MB if you have 8 Mb service
yeah. I've got 2.0 / 256 ADSL (when there's no static), which isn't all that great sometimes
a default install from the LiveCD ends up around 1.8-2G, right?
hmm, I wonder if you could apt-get remove some packages (like ooffice) before installing
I bet you can
huh - that's an interesting idea
does the install just copy the "current file system" to the HD?
yes mostly, it patches up some stuff afterward of course
cradek: have you tried much over 20in/s/s on your maxnc?
ooffice, gimp, evolution
I wonder if you can delete / uninstall things on the live boot. I'd think the files would end up read-only, unless the entire CD were in [c]ramFS
skunkworks: yes I think it'll do more, but 20 is so fast that you really don't see/hear the acceleration
SWPadnos: the root fs is extracted into ram, it's compressed on the CD
the engraver did 20 just fine.. Sounds cool.
what's its top velocity?
right, I know you can add files and install packages, but I'm not sure how you'd be able to delete packages, since there's no way to load a 700M CD into 512M RAM (to make the filesystem fully mutable)
I guess all you need is the modified dir inodes
cradek: right now I have it set to 120ipm.. At that speed I can grab ahold of the axis and stop it pretty easy.
skunkworks: what is driving the steppers?
120 is not bad I guess, since you'll only cut at 30-40 max
A parker drive set at 1000steps per rev.
set at 1.5a 75v
I need some of those.
only using 2 coils of the 6 wire steppers
that works better than using the full coils in series?
have not gotten that far yet. I would have to set the current to half if I understand it correctly.
maybe they are 1.7a now that I think about it.. Because the parker powersupply is only 3 amps and I was thinking that would be pusing it for 2 steppers.
just do it
worst that happens is the power supply explodes and catches your house on fire
oh - I was planning on trying it.. :)
I figued they built in some overhead :)
I have 2 supplies - so maybe one of them would run the 2 lighter axis and 1 would run the heavy.
oh, i was thinking you would run 3 x 1.7A steppers
but since they usually arent running at the same time it should be fine
I think that may be pushing it - but I am not against trying it..
* skunkworks needs to pick up the other 2 drives.
pick them up?
they're steppers so they're dissapating power even when not moving
but they use more power when moving dont they?
or is it less?
they are at the shop - the engraver is at the house
easy to check..
if i understand it.. if there is enought voltage to push in the supply - the steppers should always take the current the drive is set to.
unless they have an idle down when they are at rest
the coils will give off imperceptably less when moving
as they have an inductance, and the current has to ramp up
most drives have a feature that lowers the current when idle
these do - I just have not activated them - it has 100%,75%,50% and 25%
do the steppers get too hot?
have not noticed yet - only ran it for about 30 min.. it got warm
random musing; as it is now an end user can generate a joint axis error by just rotating a jogwheel quickly back and forth (with backlash comp enabled) is this behavior known?
so - with backlash disabled - it doesn't do it?
the error occurs when changing direction while the backlash comp is running
maybe if I increase f_error it wont error?
because I assume emc can't abort the backlash comp midway
so when I command a move in the other direction, it continues moving the original direction first, and errors out?
it continues moving, like an overrun, or it just cant stop in time due to inertia?
I was speculating as to the current behavior
not what it really does :)
make a plot with halscope
I can't access the machine at the moment
it should be easy to reproduce though, just enable backlash
I'll test it later when I have access to the machine
are your stepgen limits >= 1.5 * the joint limits?
hmm, FERROR seems to be greater than 2*backlash, so that can't be why
joint or axis limits?
which I assume are equal in trivkins
hmm, ah, they're not
they're only 10% greater
I could swear we had this conversation this before
I think so :-)
we talked about it being 1.5x
maybe I just didn't connect that with settings in the ini
ah I was probably not clear enough
so if I set stepgen maxvel and maxaccel to 1.6*axis maxvel/acc then it should work?
I think so
right, IMO that should be in the ini file, as it is now it just says to have it a little bit higher
* lerneaen_hydra shows puppyeyes
yeah those comments are from before this backlash comp stuff
right, thought so
so you where getting a following error?
joint axis error
what are there called in english again? http://www.promet.se/produkter/Rea/Klockor/analog.jpg
ah, yes, there we go
lerneaen_hydra: what is your website again?
here I was thinking the name was simple ;)
cradek: still there? re jmk's "discard jog requests during feedhold", does a FO of 0% count as feedhold?
I think feedhold and FO=0 are pretty much indistinguishable
I don't know anything about his fix though
I think that he used the internal variable that means "net feed rate after all feed-affecting items have been applied"
ok, what happens if you start a jog with a jogwheel, move a bit, move FO to 0, and then increase again
oh, I see
If I am right, it discards the remainder of the jog, if any
and while machining it behaves as usualy
so it doesn't discard the rest of the g1 line or anything else untoward ;)
lerneaen_hydra: what is a waterbox?
oh, it's like a heatsink except with water as a heat exchange medium instead of air
have I interpreted the gnu fld correctly in that I can take a text from a fdl document, paste it into another document (without explicitly saying where the text is from), as long as the new document is under the fdl?
