I don't think I've ever seen so much discussion about one line of code!
hi alex, haven't seen you around this late for a while
:) paul probably didn't want eric to post it.
cradek: yeah, not sure why I stayed up
wonder what to do next to emc - it's sure slowed down since 2.1 release
* alex_joni feels the same way
maybe it's about done
cradek: I think it's like the dome in Cologne
the day it will be done, the world will end
I think that yesterday a half dozen people promised to write new trajectory planners with spline support and infinite lookahead .. you can't say that's no progress.
I promise .. something
to be fair, they didn't promise to do it, they just don't see why it would be hard at all to do
(couldn't think of something plausible)
skunkworks: each and every day
for a while there I didn't think I was going to be able to make it to the workshop - but the house stuff is going well. Plus it is further off than I thought compared to last year.
don't remind me :(
yeah it's late this time
;) I have stopped bugging you
now it is for sale http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160087251047&ru=http://search.ebay.com:80/160087251047_W0QQfkrZ1QQfromZR8QQsubmitsearchZSearchQQfviZ1
rigid tapping is all I can think of at the moment.
more read-ahead would be cool - but it works fine for me the way it is.
yeah tapping would be nice. if I had hardware to use it, I probably would have done it already
kind of boring/tedious otherwise
boring rigid tapping
ahh. that kind
jmkasunich: for incremental rebuilds there's also no need to re-run configure -- that is done automatically if configure or a .in file has changed
jepler: good point, I will fix that
jmkasunich: good evening
jmkasunich: if you are staying for awhile, I'd appreciate if you read back to the discussion between me and SWP about specifying durations in HAL
I saw that
these are additions to hal_lib that comps would then make use of?
and the comps would export both seconds and nanoseconds fields?
yes, when it's appropriate
for stuff like oneshot where a long "pulse" may make sense
right - like steplen, stepspace, dirsetup, and dirhold wouldn't use the seconds part
it's much harder to imagine needing a >4 second stepspace
would ns values greater than 1e9 be accepted?
if the times aren't always "normalized" it makes the operations on them a bit harder.
I'm not sure if worrying about that is premature optimization or not
jepler: finally got off my butt and fixed the duplicate message-id problem in the commit emails
jepler: and as I suspected, the velocity changes are caused by mismatched accels
^^ with the acute check disabled
is the acute check wrong somehow?
no, but it causes (at least) the first and last segments to have differen accels from the rest
the first wouldn't have to, except when #1/#2 is planned, #3 isn't in the queue yet, so #2 gets marked acute
so you get one glitch there, and another at the end (segments -2 and -1, there is no third again)
I think there's no fix except always assuming acute (or not acute, which is not safe)
the upside is it only happens at the very beginning and very end
jepler: it could be fixed if a segment could have different initial & final accels - but I'd be scared I wouldn't get that right
you could have an acute join that doesn't affect the nearby non-acutes
* cradek talks to himself
cradek: sorry, distracted over here
and leaving for the night now
I'm glad you understand what's going on at least
no problem, goodnight
even if it's not an easy fix
I don't think I'm going to do anything
fine by me
putting the polish on this spline code is proving harder than I'd expected
SWPadnos_ is now known as SWPadnos
shininess, not people from Poland
was thinking about polish notation :D
and it didn't make any sense
the only difference between the two words is capitalization :)
I was just going to ask that.
well, that and their meanings :)
wasn't there a lathe wiki - I found the advanced features but I thought there was a page showing how to currently program threading.
skunkworks: did you try the docs?
the pdf docs, that is
oops - thanks
wonder if our -sim package would work on edgy
I have an edgy simulator machine, so I could take the time to make the -sim package work
they use different package names for some of the requirements
I don't see spending any time on it - if it just worked, that would have been nice.
jepler: have you tested a spline with all colinear points? seems you might get degenerate arcs
cradek: there are a number of degenerate cases that aren't handled, I'm sure that's one of them
gah - alex, can you configure joomla to not open links in new windows?
things like the manual, site search, etc.
SWPadnos: those are specified on each link
but yes, one could do that
I can just middle-click I guess (though that doesn't work with the search button)
it seems random though
I set them based on how I felt :)
guess I worked more than one day on it :P
jepler: about degeneracy: I'll help test when you're ready
jepler, i am looking to get some custom sheetmetal stamped for the front of a 2u computer chassis
do you have any reccomendations on a sheet metal shop that i could work with? hopefully on the west coast
nope, I don't.
