did you know 32bit windows can't see over 2tb?
I found that out today :)
something I probably should have known.. oh well.
I think disks should be able to be over 2TB, but not partitions
thats a suicide wish right there
the internet says that ext3 with 1k blocks also has a 2TB limit. disappointing.
when you have 10 TB then you can trade with other farmers
All I know is - I have the 5 750gb drives in raid 5 - it finished building and windows didn't see it. I email the company and tried a smaller 'test' raid partition of 1gb which worked. emailed the company and they said - windows 32 bit will not see a drive greater than 2TB
so now I am making 2 1.36TB raid groups
For Shits and Giggles <-technical term
says it should be done in 15 hours
nah. that'sfutile. just send me the 750GB drives, and I'l swap them out for 320GB drives that you can actually use
at no charge
fsdafsd: excuse me?
ir in this case, terabyte schmerabyte
it does make a nice chunking sound now :) like it is doing something
oh, that could be the chunk of death!
no - not the click click click (repeat) sound..
I'm still waiting for my check from IBM
I actually signed on to the class action suit against IBM because I had a deathstar drive
it was the 60GB drive that I originally bought in this computer, in 2001
I'm supposed to get a $100 settlement from them, which should buy about 500 GB once I get it :)
so I bought a laser
anyone know how thick of steel I can cut with only 45 watt ?
I might be able to pay 6k for an opensource version of autocad
anyone intrested in an undertaking like that ?
half upfront half on completion
I think there are websites that help people find open source programmers
that might be a good thing to try
have you looked at qcad?
do you have any idea at all how much programmer time would be needed to make something like that?
that will buy you one copy of autocad, not its entire development
but this is the emc-devel channel anyway
you are talking thousands of man hours
snap to the center of a cirle would not be hard
opengl makes that stuff easy
jmkasunich: did you see my maxkins pastebin?
didn't study it
I haven't tried it yet but it seems like it might be right
you should make a vismax.py
I might try it as INVERSE_ONLY kins
yeah that would be nice. I could even make it to scale.
one of these years I want to make a to-scale visbport
all I need is a bport to measure
bring your tape measure and head on over
I'll start the coffee
be careful what you ask for, you might get it
take your android too
cradek: you remember the original PC power supplies, with the female IEC power socket on the back for the monitor?
ah, the good old days
the good old days of the burned-in green screens with no power switch?
got one laying around? or one of those female IEC connectors?
I was thinking of the fine amber screens, but yeah
do you need the combo in/out, or just the female?
jmkasunich: do you need the power supply or the connector?
I have bunches of the male ones
the connector - I want monitor power to come out of the electical box
I suppose I could use a regular outlet, but that will take more panel space
do you have the male to female IEC cord?
I have some short male-female IEC cables - you could use something like that if you don't mind a pigtail
I think so (somewhere in this mess)
that would seem harder to find
a single outlet (the little square one) is no bigger
I have IEC cables
some big thick ones
[02:14:23] <cradek> http://timeguy.com/cradek-files/cnc/lathe/DSCN6296.JPG
like these little outlets
you just make a square hole for them to snap into
then you're not screwed if you end up with a monitor with captive power cord or wall wart or something
I just dug thru one of my IEC cord boxes
I have a short male to female (about a foot), and a male to bare wires (6 ft or so), no male to female
I think they haven't been made (for mass market) since the AT days
oddles of regular plug to female IEC of course
I may have one or two but that's all
and I got rid of my green screens long ago :-)
the little square 120V outlets are probably the way to go
that panel is a bit down the road though
I even put one of those in the dash in my (last) car
with an inverter?
it was nice to have an inverter available but not in the way
* jmkasunich chops the ends of of some IEC cables
(computer power and monitor power are going to be fed from some DIN rail terminal blocks
looks like IEC female snap-in outlets can be had if you really want them: http://www.mouser.com/catalog/632/961.pdf
and cheap enough that scrounging doesn't even make sense
but as cradek pointed out, the cable is the hard part
for some reason I thought I had the cable, but either I was mistaken, or it is buried somewhere
note to self: don't secure coiled cords with masking tape before storing for several years
I like the removable cable ties
it was only this one cable, I don't think I was the one who taped it
yeah that too
fortunately goo-gone is cleaning it up nicely
goldmine-elec.com has this wire harness tape that works very well for keeping wires bundled for storage
where is the best place to buy a 100 watt laser tube ?
[02:31:03] <fenn> http://www.goldmine-elec-products.com/prodinfo.asp?number=G14925
oh yes and IEC sockets: http://www.goldmine-elec-products.com/prodinfo.asp?number=G15608
or is that the wrong end
that's the common one
fenn: jepler posted a catalog page (mouser) with both
and I've decided not to do it that way anyhow
I like those little square snap-in outlets
it has a computer now
I thought I was supposed to include "rtapi_math.h" but I'm not getting a hypot prototype
[5364862.130307] maxkins: Unknown symbol hypot
oh I see why
oh well that's easy
adding just the prototype fixes it?
I just #defined it the obvious way
motmod requires kinematicsForward() even if type is INVERSE_ONLY
yes -- I don't think that's avoidable
I get following errors turning machine on - I wonder if it's using kinForward()
the joys of debugging in realtime
it worked in --enable-simulator?
well who knows about FE
I didn't see any obvious position jumps but there's nothing checking it really
errr I mean when going into world mode
and halscope crashed when I clicked "force"
that's not good
not good at all
my fault (maybe)
oh halscope? not my fault
I haven't found it yet, but I broke something when I added 'continuous'.
gimp's "perspective" tool is pretty neat
I couldn't get a decent camera angle to take a pic inside the box, so everything was all distorted
yeah it is neat
gimp corrected it (mostly)
grumble. an annoying bug in the gutsy 'rxvt-unicode' package and they mark it 'Fix Released' based on the fact that the package that will be in Hardy Heron 5 months hence may or may not have the problem fixed.
[03:49:58] <jepler> https://bugs.launchpad.net/ubuntu/+source/rxvt-unicode/+bug/144416
(the package is only missing almost all of its documentation)
once I get a FE in world mode, I can't turn machine back on - I get constant FEs
oh without forward kins, it can't set cmd to equal fb

someone stop me before I hook stepgen following errors to feedhold and call it joint limits
why would you want to do that?
because joint limits are hard and stepgen etc already knows when a joint limit is being exceeded
well I'm probably going to try it anyway

hrm. why didnt i get that error
probably because you were on sim?
you're using M_PI instead of M_PI1
you could also add a define for M_PI to rtapi_math.h
that header file got only the bare minimum needed to make emc compile, so there are gaps discovered from time to time
EMC: 03fenn 07TRUNK * 10emc2/src/rtapi/rtapi_math.h: M_PI seems like a pretty standard thing to use
fenn: what it M_PI is already defined?
then it gets defined twice?
* fenn waits and sees
also, haven't you just broken all the "non-standard" code that used M_PI1?
I think you should grep for M_PI1 and change any you find to M_PI
one last comment, did you drop the L from the end on purpose?
It's M_PIl -- the constant pi in long double precision.
duh, so it is
my point is still valid tho, that one is no longer defined, so unless no code used it, things are gonna break
does the L cast things that use M_PIl into a long?
why is one no longer defined?
I mentally saw a - in front of the first line in the diff
thought you changed the name instead of adding a name
oh right - and I have one of those fonts where I can't distinguish between 1 and l, so I typoed the variable wrong
is defining something twice bad?
like, say M_PI is already defined because i'm running sim
I believe your definition will silently override the previous one
in this case that seems harmless
EMC: 03compile-farm 07BDI-4.51 (18.104.22.168-rtai) * 10emc2head/: build PASSED
with doubles, it's often better performance-wise to define a static constant instead of a #define
SWPadnos: not in a header file I don't think
EMC: 03compile-farm 07Ubuntu 5.10 (breezy) realtime (2.6.12-magma) * 10emc2head/: build PASSED
only if they evaluate to the same value -I think that's a warning, whereas a redefinition can be flagged as an error
jmkasunich, right - there are problems using static const in a header, but it's still better for performance, even though the memory footprint will increase somewhat
that is a bit of a generalization
static var better for performance
if the var is rarely used it makes little or no difference
sort of - it ends up being a cache coherency thing at some point
when you use a double, there's no way to directly load a constant into the FP register, so you have to load two 32-bit registers, store the two words somewhere, and load the resulting double from memory into the FP register
if you have a static const, then the load happens directly, without the int registers being involved
EMC: 03fenn 07TRUNK * 10emc2/src/rtapi/rtapi_math.h: resolve any ambiguity in #define order
or something like that
isnt that the compiler's job?
that's how the compiler does things with double constants in the code
and does it do something different with a #define?
(i think you mean longs btw, since doubles are 32 bit)
I don't think it'll automatically make a static var and load it (though it may now, this was a year or two ago that I heard/saw this trick)
a #define is a constant in the code
vs. a const var
no, floats are 32-bit
doubles are 64-bit
and long doubles could be 80 bits on Intel architecture machines
don't the FPUs have a few constants built in?
like pi and e?
or am I confused
#define M_PI acos(-1)
(not that the compiler is gonna recognize that fenn's constant is PI
it's a small issue, especially because FP isn't generally used in the very fast thread
5? years ago I put some stuff in a box and carefully labeled it. Can anyone tell me where the box is?
in the barn
under another box
jmkasunich, take a quick gander at the pluto-step code - there are some hard-coded constants in there to deal with FPGA limits, and they may also affect how it deals with the position command
I know he's not describing a problem very well, but there could be a problem
I'm not claiming that he is full of shit, I'm claiming that he isn't giving us enough information to go on
I do need to run now - see you
heh - that's true enough
I didn't think to look in the barn... duh
sometimes I forget that to find something, you have to look where you haven't yet looked
