is emc use s-curve acceleration and deacc ?
or trapezoidal ?
alex_joni: know about any plans to make it s-curve or selectable ?
micges: only if someone contributes the code
it's pretty hard to implement
I think cradek tried, but didn't succeed
s-curve as such isn't _that_ hard, but doing blending, and threading and all of that is hard
yes blending.. nightmare :)
blending by itself is not hard either :D
I was on 4 day service in country, didn't make chance to recreate hm2 stepgen bug :|
tomorrow will be the time
I know seb reproduced a bug you reported and is working on it
not sure about the specifics though
yes but he hasn't get all info (me too)
nex week Im going to start reimplement all my finctions and goodies in emctask
will notice you all about progress
I've reached limit of speed of python
I've plan to bulid small fast (about 20000mm/min, acc=2000) machine to tests
I forgot: I've notoced error in emctask:
when I have XYZ machine, then selecting some vector to run it will do it correclty
but when I add simple U axis to that config then run from line N then all restarts are from vector N+2 or N+1 index
througly tested, number of emc axes change behaviour of this
EMC: 03bigjohnt 07v2_3_branch * 10emc2/docs/src/config/ini_config.lyx: remove section number from axis display items
EMC: 03bigjohnt 07TRUNK * 10emc2/docs/src/config/ini_config.lyx: remove section number from axis display items
cradek_ is now known as cradek
are you guys sitting next to one another?
cradek: my backpack is on the dlt tapes. I think I will remember them :)
ah, thanks! I forgot about those!
steve_stallings is now known as steves_logging
Is the gang all there? ;)
skunkworks892: not everyone yet
john k and john e are supposed to arrive tonight
not sure when steve s or steve p show up
Did you end up following the bus?
* alex_joni feels bad he's missing fest again :/
alex_joni: you need to talk your (is it father-in-law?) into buying a private jet...
for the company.. ;)
without the "-in-law"
ah - ok.
we're a bit far from a private jet :)
not to mention one that makes it safe over the atlantic
maybe you could get a concord cheap ;)
for a retrofit :P
maybe a TU-144
ah - soviet
jepler: how setup are you to make circuit boards? (if someone where to bring bits and copper clad?) (and the zenbot was somewhere that didn't annoy people) (and...)
skunkworks892: I hope to be able to make boards here
skunkworks892: I have to get a stepper driver, I think I have the rest (bits and single-sided copper clad)
jepler: are you still using the pluto for step generation?
skunkworks892: no, I'm in the middle of converting it to mesa
skunkworks892: but the main problem is that I fried my xylotex
there are a number of things I can borrow, but then there's the wiring to do..
yeck. I hear that is easy to do.
do you know what it was? short? unplugging steppers with it on?
one of the stepper wires came out of the screw terminal and shorted to gnd
I think that what that does is make it drive 27V into 2ohms with no current feedback .. and it cooked the chip before the so-called thermal protection shut it down
27V at 2ohms is only 10Amps or so
jepler: is it the L298 based board?
skunkworks892: no, a3977
anyway, I have a couple options here at workshop to get the zenbot running, and after I go home I'll decide what to buy as a replacement
is there something you want to mill?
I thought I might have some l298's
thanks, but that won't help
I was thinking a fast small machine would mill a couple drive boards in less than the 3 hours it take me.. ;)
ok - maybe 2 hours
jepler: plus wouldn't it be a good experience for you to do double sided boards? ;)
EMC: 03cradek 07TRUNK * 10emc2/src/emc/iotask/ioControl.cc:
EMC: FMS is some kind of tool tracking. Matt S says EMC never did anything
EMC: with it. Somewhere along the way we started assuming and then
EMC: requiring the tool number and FMS number to be the same.
jmk-wvm: ! you made it?
good night all, have fun at fest
skunkworks: yep, I'm here
steves_logging is now known as steve_stallings
is jelper's dead Xylotex board there? I have some spare A3977 chips that fit it
steve_stallings: no, it's at home
well I do have the rig that runs my micro mill at the shows, 3 gecko 251s a breakout board that expects a parallel port, and power supplies
all total 14 pounds of my 50 pound checked luggage budget, will anything be accomplished by my bringing it
I get there Friday night late
cradek: did the supply for Sam's servo make it?
last call for electronic widgets for me to bring will be noon EDT Friday, via PMDX support email contact, not IRC
