Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2007-09-06.txt
I can't see any difference between the velocity or acceleration profile for keyboard incremental jogging vs jogwheel incremental jogging
should you ?
my mill will stall during a jogwheel jog, but I haven't gotten it to happen during a keyboard jog
does it happen for a quick spin of the wheel, or slow steady turning, or?
most often when I try to give it a quick spin
I should probably just turn down my accel and vel a few percent and see if that fixes it
the jogwheel I have is pretty noisy so there are not only stops but there are 1-count reversals (maybe larger) as well
can't achieve that with keyboard incremental jogs: http://emergent.unpy.net/index.cgi-files/sandbox/typical-jogwheel-jog.png
yeah I know
when it doesn't stall, though, it's fairly usable
what kind of encoder is that?
it's a mechanical knob, 24 count / 12 detent per revolution
crap but the only thing I have
two carbon rods from old batteries, dragging on a quadrature wheel cut out of old chimney flashing with fingernail clippers
jmkasunich: I saw the trench pictures. better today?
still not done
I can flush, but I'm doing it with my neighbors water
having a poop pipe that works is a good thing tho
Yes - It is :)
those poor guys
especially the lead plumber - his office sent him out with one apprentice, and somebody screwed up and left out an important part, which the apprentice had to go and fetch (1-1/2 hour trip)
jepler can you put a rc filter on the switch?
fenn: yes, but I'd have to redo the board it's on
so the lead guy is down in the trench fighting with rocks and climbing in and out to get stuff that the apprentice should be fetching
so the lead plumber had to do the manual labor ;)
he works his ass off whether the apprentice is there or not, but it's wastefull and inefficient to have him schlepping tools
I did quite a bit of that today, just to keep things moving
the rocks in this dirt are just unbelievable
there's a 12 pack of Killians in my fridge with the guy's name on it for tomorrow
(well, 11 pack now, I was thirsty)
I may have to issue a mea culpa on this one .. I lowered my maxvel 10% from 1.2 to 1.1 (ips) and can't get it to stall
so it's more that the jogwheel "random position generator" was better able to stress the machine than gcode or keyboard jogging was... ?
maybe that's what the random number generator component is good for
yeah, keyboard or g-code usually only goes from 0 to 1, not -1 to 1
I guess g-code can do - to +, if you write it that way
:) I only needed a plumber to put the septic in the house previous house I built. (for some reason you need a licence to do that;)) but he was excellent.
the guy thats been working here is great, but his office is staffed by idiots
the job was quoted as three men for three days
day 1, I got one man for half a day
day 2 - two men all day, and a third for half a day
today, 2 men all day
total man days: 5
quoted for nine
if they had sent 3 men each day it would be done by now
I have this sinking feeling I introduced a bug, or else revealed one in axis
frequently I hit F5 to issue an mdi command, but nothing happens .. switching tabs sometimes makes it work
the bug I fixed had to do with MDI commands being "partially accepted" in machine off mode ...
anybody else seen this, or am I unique?
and for that matter, why is g28 g53 z0 rejected?
"go to Z=0 in machine coordinate system, then go to G28 home"
G28 and G30 are explicitly defined as being in machine coordinates, I think
no, when I programmed G28 Z0 it seemed to move in the active (G54) coordinate system to Z0, then move to G28 home (in machine coordinates)
ok, I didn't understand exactly what you meant
that's OK, that gcode I mentioned may not be wanted by anybody
g28 is so screwy
g28 z0 makes only the z axis move (to relative 0 and then to absolute 0)
I think the thing you want is not possible
jepler: your indicator is here
cradek: ok thanks
I got feeler gauges today too
I guess you could get a rough idea of alignment with those
the 2" chinese indicator I got is interesting - it indicates 0.000 and 2.000 just fine (123 block) but 0.998
so who here suspects the $10 chinese indicator and who suspects the Browne & Sharpe 123 block?
cradek: yeah I thought about that
jepler: come by anytime - I'll be playing in the garage
cradek: thanks for the invite, but I doubt I will
cradek: bring the indicator to the office tomorrow instead?
iirc, the holder needs doctoring
I haven't even opened it yet
you thought that part could be turned down to 1/8 ...
I might have a look tonight - if it's soft it'd be easy to turn down
if it's hard, you'll have to figure something else out
let me know
