i'm not getting any email from the forum....is that just because it's new?
did you subscribed?
he is a moderator in Milling and Turning
no new posts I assume
I just posted one piasdom so you should get an email in a bit
jthornton; still didn't get an email
i got a few at the start,but none for about a month
I'm not sure how long it takes or if it does it more than once a day
* alex_joni just uses rss for the forum
alex_joni; don't know how :)
never use rss for anything
it's stopped snowing, there's a few inches of crusty frozen slush & powder
it's gonna be cold for the next couple of days, so it wont be all melted by the weekend
but i bet the roads will be easily travelled
so you should come!
I assume the snow removal people know what they're doing there
we're getting snow friday :) we get about every ten years
have you had a chance to try the hm2 encoder nan-finding patch i sent you?
unfortunately no :|
ok no rush
but I remember to do it if I can ;)
sadly only one servo machine have this bug
you have other machines that dont show the bug?
is the machine that *does* show the bug otherwise stable? passes memtest86 & other stress tests?
I have 6 servo construction and only z axis on one machine shows his
yes working 24/7 from about 16 months
seb_kuzminsky: have you tried testing with bogus quadrature?
cradek: tlo_9 will be ready for test, just extending python interfaces left
cradek: no... and i'm not sure how to do it
here are the "controlled input to the encoder" tests i have now:
[16:48:44] <seb_kuzminsky> http://highlab.com/~seb/bzr/fabrication/projects/emc2-hacking/hm2/test/loopback/gpio-to-encoder/
I was just thinking if it's one axis on one machine ... that's one encoder, could be a bogus one
that makes sense
gray code is pretty hard to mess up though
the only way i can think of is to have both A and B inputs change at the same time
yeah that's exactly what I meant
which i could simulate by running the same gpio output to both encoder inputs
ok i'll add a test for that
i'll have to change my test setup wiring harness but that's no big deal
shot in the dark...
dark is all we got at this point :-(
but there is no visible position loss
but I can measure it
it would take a LOT of counts to be visible wouldn't it?
the only way i could see for vel to go to Inf and pos not to be affected would be if it somehow got confused and thought dt was zero
the patch i sent micges checks for that before using dt, and logs a warning
but it makes no sense that it does that on just one encoder on just one machine
if it was a time-tracking bug in the driver i'd expect it to fail all over the place
micges: what OS and kernel is on that machine?
I spent half a day trying to reporduce it on another servo
it's not SMP is it?
just our usual kernel?
no linuxcnc image
This is a bit off topic - ok it is totally off topic but I'd like you opinions....
I have a customer asking for recommendations on NAS servers - similar to this
[17:29:52] <Dave911> http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16822102030&cm_re=nas_raid-_-22-102-030-_-CustomerReview
I thought someone was talking about one of these a while back. Any experiences good, bad, ugly ?? :-)
I have an old NAS box that has worked well for me but these guys really need a box capable of RAID. Mirrored or Raid 5.
Dave911: you could try asking in #emc
OK, thanks I'll do that.
seb_kuzminsky: I wonder what hm2 does when both channels change together? I think some systems note/log that error somehow. I think it always means you've lost position.
there's a bit in a firmware register that i think reports this condition to the driver, but the driver doesnt look at it yet
cradek: on the bots we work with (the really old ones with encoders) such a failure stops everything
i remember you asked for this failure mode to be exported to HAL so you could estop the machine
oh did I? :-)
I'm predictable I guess - kind of the same from day to day, if forgetful
another thing that gets checked is A vs /A, B vs /B and Z vs /Z
I'm surprised anything reads those separately - I figured they always just went to a differential receiver
I'm trying to revive an 1990 bot
and since there's no encoder connected, that bit me
OK, this question is actually development related.....
What debugger do you guys use for Python development? WinPDB ?? Or ?
Like everything else Linux there seems to be 10 different ways to debug Python code
I have never used a debugger for python code
I'll take that as a yes ....;-)
I use a debugger for C all the time, but never for python
I'm not sure what to ask next ... but how do you do that without a debugger have you just been coding with Python for quite a while ??
no, I suck at python, but it's easy to add prints here and there
what I wish is I could have it run to a certain place and then give me the REPL prompt
OK, that is how I used to do old basic code debugging way back when
maybe that's what a breakpoint in a python debugger is, I dunno
I've never bothered to figure it out
The WinPDB debugger is not exactly obvious in how it works, but then I haven't spent much time with it yet either. It seems to have a lot of non-obvious features
Well I guess I will plug away with WinPDB for a bit and see what happens.. Thanks!
let us know if it's useful
I will.. I'd really like to do breakpoints etc..
Is there any written reference you use for Python or do you use the man pages or docs at Python.org
OK, I'll just do that then also...
wow - now the snow is really coming down.
skunkworks_: testing your new garage roof?
as we speak I guess. ;)
still just a dusting - but white-out for a while there.
skunkworks_: and here I am in t-shirt and shorts
