so, here's a great example of "specsmanship": http://kensolar.com/tek9.asp?pg=products&specific=jnnngoi8
"celluar phone, 6A"
you gotta be kidding
(thats supposed to be at 12V
that's just a typo, it should be .6
72 W would melt the thing
which works out for ~100 hours with a 63AH battery
what gets me is that they talk about 1500W continuous and 3000W peak power, but the panel you get with it is only 110W
and 3000W from a 12V battery had better be a short peak demand
I knew right off that they were using the battery to get those powers
battery + 15 panels probably
1500w continuous means until the battery is dead.
could be, but even so, that's ~125A from 12V
better be a good battery, like from a car
well, 63A*H * 12V = 755 WH
which it does look like
right, 1HP for 1 hour
so you aren't gonna get more than half an hour at 1500W
so much for that 40 hour fridge
judging from the pic, it is a car-sized battery
probably deep cycle
my sister mentioned this as a possible solution for power for the next few weeks, and I quickly pointed out that she wasn't going to get what they were implying she'd get
there was actually a 'how it was made' show on how batteries where made.. It showed how a deep cell cycle battery was made and compared it to a normal car energy.. I alawys wondered if there really was a difference.
well, what's the difference? :)
iirc - it had something to do with how the lead was shapped.. but to be honest I don't actually remember
extra surface area maybe
there was a discovery announced today or yesterday about using some carbon material in ultracaps
had something like a football field of surface area per gram
should be useful in ~5 years or so
I just saw a video on a concept 3 wheeled wearable cycle. they actually mentioned a ultra caps.
is a motor cycle still a motor cycle if it doesn't have a gas engine.. Just my feeling - I think of gas engines when I think of 'motor cycles'. (that might be too far down the rabit hole)
[01:17:39] <toastyde1th> http://www.boasas.com/?c=1006
I had thought about making a cycle with 2 servodisc motors
or maybe even one
you can get 50HP discs that are about the size of an average wheel
this months Circuit Cellar Ink has an open-source electric engine controller
3-phase, about 110HP max - depends on the power stage
this is cool http://www.sciencefriday.com/program/archives/200808221
Just need some fast diodes...

cradek_ is now known as cradek
admittedly I didn't rtfm - I am running EMC2 with the AXIS interface - I edited the .var file to change a value for my G55 wpc. It didn't change the position on the table. What do I need to do to read the change?
I am currently reading the manual
steves_logging is now known as steve_stallings
stuste1: don't do that - use touch off, then change the pulldown menu to G55
stuste1: or, use G10 L2 P2 to set G55 offsets if you want to specify the number
I just need to move the Z down by .020. I see the manual says to issue a reset after editing the file. I have always used the G10 until now. Is there a command I can use to issue a reset?
I do not know of a reliable way to make emc reread but NOT write the var file
I bet what it did was immediately overwrite your change
if I touch off to another (false) wpc will it reread the file?
it will write it
if you edit the var file, do it without emc running, then start emc
can't you do a #var=whatever in mdi?
I will be able to tell by looking. It writes to 6 or 7 (a bunch) places. I only need 3.
skunkworks_: yes that might work, not sure
each g5x has 9 variables for it
on this machine anything past 3 is just plain arrogance (or wishful thinking)
I am talking about decimal places
I use 9.801 - I can only dream about 9.8012794
EMC dreams for you
At the very least I need a reload wpc (like the reload tool table)
I would like to see the control reread the wpc and tool table on every line
SWPadnos: I can dream on my own
EMC dreams more accurately I guess
as far as I know, using '#var=whatever' in mdi to change the coordinate system you're not currently in will work
it won't change the one you're currently in
(I'm not sure what advantage it has over MDI'ing G10L2 though--particularly since that will successfully change the coordinate system you're in)
I like that better
yeah I tried it for the current system and it didn't work
g10 is better in all ways
it even gets units right
thanks guys - off to make more chips - should have video today - I have already cut the top of the block - I will cut another one for the video
is this the 5 axis code from apt?
neat. I'm looking forward to seeing that.
so you made an apt postprocessor that generates 5 axis gcode that works for emc?
It looks pretty good - The program says it is a 59 minute program - I will have to edit it for youtube so I may not have it published today
yes - just remove the pivot length and tool length calculations
I wonder if LiVES has a retiming function
slick. I'll have to figure out how to use that.
Linux video editor
[14:12:32] <SWPadnos> http://lives.sourceforge.net/
will look at it
ah, it does do retiming
"Resampling of video (time stretching) to any frame rate (1 to 200 fps - accurate to 8 decimal places); option to auto-resample or speed up/slow down between clips."
huh, I wonder why limit it to 200fps -- that won't get a 59 minute program down to youtube-length
do it twice
(though if that's axis's program time estimate, I would trust it even less for 5-axis code than for 3-axis, and I don't trust it much there)
things get pretty choppy when you try to change the time scale too much. The best system I've seen was able to do a 10:1 slowdown (I don't know what the speedup range was)
that was fro a million dollar range editing package
I wonder if it's multithreaded
hmm, got a number of questions
the g1 code is *always* a straight line isn't it?
depends how you define straight line
so the code "g1 x10 y10" followed by "g1 x20 y0" is supposed to bw two straight lines
g0 x0 c0, g1 x1 c180 will cut a sprial since c is rotary
but in a cartesian (xyz) machine, yes it's a straight line
i got a smooth corner rather than two lines
mr_boo: there are some cases where blending can occur between two straight lines
this is shown in the graphical representation
that is because emc2 uses G64 by default
put a G61 in your program at the very top
you can control the corner deviation with G64 P[tolerance]
right, or specify no deviation with G61
lets try it
mr_boo: read this for all the gory details http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TrajectoryControl
it explains all (?) the issues very clearly (?)
cradek: is fast today
[14:32:53] <BigJohnT> http://www.linuxcnc.org/docview/html//gcode_main.html#sub:G61,-G61.1,-G64:
g61 did the trick
be aware that you want the slightly rounded corner in most cases of cutting real material
cradek: he's not cutting :)
spooling some wires around
ok then, G61 it is
if I remember it correctly
now it winds pretty good
i can't document my progress since this rtai kernel doesn't appear to support my cellphone
unless i try to upload it on another machine
to see it in action is eyecandy
another youtube video is always welcome
not half as impressive as your stuff but i'm a beginner after all
my progress is also thanks to your help
that's the reasone there are people in this channel
I'm not sure I know of anyone else using emc for wire winding .. it's neat to hear of new applications.
I agree. making a new kind of machine is neat compared to boring old lathes (haha, a lathe joke)
mr_boo: there's a page where you can add it: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos
they're in a fancy file format, http://www.carmi.se/misterstarshine/img/MOV00221.3GP
don't know about the quality
gotta see it myself
* mr_boo installs vlc to be able to watch his own video
i bet the cellphone has crappy video quality as well
you need to get ahold of the upcoming camera from canon .. 21 megapixel stills, 1080p high def video, up to ISO25600 sensitivity
that video quality was *not* impressive
it'll only cost 3300 euros bundled with a lens!
don't buy the overpriced k770i
I needz an injection of moneys for that camera
only 3300 euro, i'd pay that with cash
I'm just happy because now I have another feature (video) to wait for in canon's rebel line, and I can put off replacing my camera for another year or two
I need a body to go with canon lenses I have
mr_boo: neat video
if they're EF, pick up one of the drebels. I have the original digital rebel and it's a fine camera. There have been enough reivisions of the drebel that you should be able to find some pretty attractive used prices
jepler, been looking of epay for a body (have a dead body here)
looks like you've got it running, mr_boo
the video you see is 0.13mm wire onto bobbin
now i'm dealing with 0.07mm
bleh vlc fails on my box
cradek: the control overwrote the file - my edit didnt stick - using MDI the G10 worked
I get the program exceeds the motion limit every time I start the program. The machine does not exceed the limits when I run the program. If I had to guess I would say it does not take the W axis (and tool length) into consideration. Just a guess.
Is it possible to disable that 'feature'?
If I would like to see a pull down box to adjust G55 (with set and increment) should I log a feature request?
do you mean you get the "program will exceed limits" dialog when you try to run it?
I have seen that when I have T1 M6 G43 all on one line, but if I put the G43 on the next line, it goes away
I have the t1 m6 on one line and the g43 on another line - maybe I should combine them
hmm, then the problem is different
I don't have negative offsets
I don't think negative offsets are required to see this bug
I am sure they are not required to see the message on my machine
but I don't completely understand the bug
My only problem with this is if we begin ignoring warnings when do we respect them?
surely it would be better to give the warning only at the correct time
do you move W to 0 before you invoke a tool change?
off to reprogram the part - I need to use a smaller diameter tool to see if the surface finish (mismatch) is better
possibly, UVW are not moved to tool change position
I will try that
I get a little mismatch (.005 - .010) between tool paths on the radical tool axis change section. The flat section matches good.
I am finishing with a 1 inch cutter - I will change that to 1/2
what is the mismatch?

a new machine is going to be delivered tomorrow... they already put a huge forklift outside to lodge the machine in..
problem is.. that forklift is 10cm too high to fit trough the front gate.
I've been there
cradek: no, this is the 3rd time thats happened.
time to modify the gate
renesis: already did :p
you guys need to take better notes
renesis: we did
we asked for a forklift that isn't higher than 2.40m, the gate is 2.50
renesis: don't have any
we got a forklift thats 2.60 high
thats not cool
maybe you should have said "8 feet" haha
cradek: we use the metric system..
no it doesn't :p
uh-oh, I tried to make a joke but unwittingly started a conversation about the metric system
well, somebody is gonna get fired soon there aswell
1) send out 200 pieces short.. he re-set the counter so it looked like he made more parts. 2) crashed a brand new machine 3) 4000 pieces made wrong,.. never checked them,.. only 100 out of that shipment were JUST within the limits.
thats just the list for this month
owell.. Gonna figure out how we'll get the new machine in tomorrowmorning.. prolly going to have to take the turret off, spindle motor, part of the chassis,..
That, and i need to finish my PCB.
has anyone here used Zoli's board?
fragalot: the board on this page? http://pminmo.com/l297-8/l297-8.htm
that's the board cradek uses (with some small mods) in his small mill, which are mentioned at the bottom of that page.
he's pretty happy with it as far as I know
pminmo, the maintainer of that site, drops by this irc occasionally
I wanted to know if the PDF is just "print&order", or if i had to resize it
(saves me the time printing out & checking xD)
ooh, it's got a scale on it..
at the time cradek made his boards, there were eagle .brd and .sch files available for download, so he didn't do it that way
yeah, thats a shame
I wanted to replace the voltage reg with a 7805, since i won't run at those high voltages anyhow
whee, it is
well that failed.
I pushed too hard on the iron,... instead of nice traces, i got a black blob xD

ffff is a noise
I have 3 dual pentuim III ibm Eservers.
wanna see how has more bogomips?
looks like about 2500 bogomips to me
my VM has 3500 :D
on one core
darn, doesn't show a total, this machine has 16x5852 = 93,632
oh, my laptop has 4400 on each core
I should check the phenom and Q9650 machines at some point
some Q thingie
I have an in with a banks IT department.. boy do they throw away a lot of good stuff
I just go 2 hp color laser printers and 4 4000 series
lots of pentium 4 class computers also
network and duplex
I just fixed my 2605dn
dust on the laserscanner mirror for magenta
it's a huge PITA to get to that
alex_joni: one of the color lasers we got was a 2605dn - it is at home now ;)
seems to do a nice job printing
man. when I kno people at a bank, all i get is useless 1" binders
skunkworks_: if you'll see magenta fading, ask me for an URL
they got bought out so the name changed, rendering the old binders inappropriate for official use
we also got a 2500 hp color.. not as nice and needed a little tlc. (someone screwed up the tray so it never thought it had paper.)
skunkworks_: cause it will.. it's just a matter of time :)
they say it's poor design
heh - mirror points up? ;)
and no seals on the laser scanner
my printer had it after 6-7 months
sent it to service, they replaced the laserscanner :/
I am suprised it does as good as it does then as it has been rattled pretty good for the last few days
shakes the dust off
now it did it again, 1 month after warranty expired..
so I fixed it myself.. 1h of messing around with it
I'm sure it can be done in < 20 minutes
hp printers are usually a pain to get into the first time.
yeah, and each time you get more and more leftover screws
after that there are half as many screws :)
so less to take out the next time
the eservers seem to run opengl pretty smooth.. around 10us latency
how big are they?
about 2 inches thick
and full rack size
19" x ?
about like this http://cgi.ebay.com/IBM-eServer-xSeries-335_W0QQitemZ150294654869QQcmdZViewItem?hash=item150294654869&_trkparms=72%3A1209%7C39%3A1%7C66%3A2%7C65%3A12%7C240%3A1318&_trksid=p3286.c0.m14#ebayphotohosting
christ that's a huge URL
stick it under a desktop mill, no-one will find it :)
i think if i put that url under a desktop mill it would still poke out
yay, zenbot is running again with its new acme screws
time to see if it still has measurable backlash (cradek is betting that it doesn't)
does everything seem free?
cradek: yep feels fine, sounds about like before
sweet - with dumbster nuts?
skunkworks_: from dumpstercnc.com
.. actually instead of doing that I'm doing lots of rapids and seeing whether it will stall .. so far so good at [AXIS]MAX_VELOCITY=2.0
wow, that's fast
what have I misconfigured in my inifile? going on a diagonal in all 3 axes I get a velocity of 198, while my math says it should be 208. I get the 120 I expect when a single axis is moving. [TRAJ]MAX_VELOCITY = 3.30 left over from from some earlier tuning effort
3.30 * 60 = 198
er, oh, duh
I didn't even bother taking 3.3*60 to check, I was certain it was "big enough'
iirc, you can just take that out instead of worrying about what's big enough
oops, it finally stalled
I think that default was changed in trunk only, but I'm not sure
which one stalled?
I think I'll go for 1.5 for now ..
* jepler (heart) margin
luckily, there's rarely a large cutting load going up
how many pulses/sec is that then?
^when going up
so it was 51.2kHz at 2ips
nice.. I assume pluto?
16TPI, 1.8 degree, 1/8 microstep, direct drive
well.. good night all
see you later Alex
old "X" backlash: .0093 inches. now: .0015.
The indicator is moving around (e.g., rotating slightly in the spindle) more than that over repeated measurements, so I'm tempted to say: backlash: less than accuracy of measurement
* jepler declares victory
jmkasunich: in cradek's expert opinion, those rails on the zenbot are drill rod.
I bet he's wrong
I say they're bamboo
you just don't like anybody's guesses, do you
drill rod is a nicely heat treatable tool steel
those rods could be made out of "ordinary" steel
something like 1045 TGP (turned-ground-polished) for less money
less money is good
well, loks like it's time for me to run. catch you all from Germany
see you all SWPLinux
I hope your travels go smoothly
have a safe flight
yeah, what jmkasunich said
I sure hope so :)
I have a fine rear facing seat, so I should be better off in most types of emergency
6' piece of 1/2" 1045 TGP from metal express, $22, 3' piece of 1/2" W1 drill rod from mcmaster $24
what you guys making?
BigJohnT: speculating about what metal one of the few metal parts of the zenbot is
my cnc machine
the diff is even more for larger sizes - 1" drill rod is $74 for 3', I can get 9' of TGP for that price
[22:10:27] <jepler> http://axis.unpy.net/files/01188441458/img_7045-medium.jpg
you talking about the two rods on the Y axis?
yeah ( and I assume there are similar rods for X)
Z too, can sort of see them under/behind the dremel
yes I see them
do they ride in delrin bearings?
I think they just run in holes in the plastic framing
which is some kind of hdpe I think?
yes I think so
like those opaque white cutting boards
kinda looks like delrin that I use a lot
making a new one?
no, we were just speculating on what they used
like I said, making noise
all we need in here is a pot-bellied stove to sit around, and a can to spit baccy juice into, and we'd be just like a bunch of old-timers sitting around the general store
I use to chew but grew up...
yup.. a lil brown bag in your pocket...LOL
and out a bit :)
I should head off to the spectacles store
ok if I do a "loadusr -w classicladder" in the HAL Configuration window will it work as I expected
I was getting ready for bed last night, and "sproing", part of my glasses headed of into nowhere land, and the side fell off
dang I hate when that happens
you wonder where those black holes are on the floor that swalow up small bits when you drop them
been there hate that
I bet they won't sell me a new temple piece, they'll want to sell a whole frame
naw a temple they should sell ya..
put some white tape on it
I'm a machinist, I could do better than that
9^BigJohnT: I'm don't think you want -W or -w there. you don't care to wait for the component to be created (it's not followed in a hal file by link lines) and you don't want to lock up the hal configuration window until it completes
ok, thanks jepler
yep, got a better response without the -w
ok, I have a dc servo motor with encoder and a stepper motor. can emc be configured so that when the stepper stalls the servo pid takes over, and vice versa? I have downloaded emc but when I burn it to CD I get an error.
have you RTFM?
that's not an error, that is a filter
I didn't get video today - the cut surfaces look very nice - I will have an inspection report tomorrow (from the CMM) - I will get video tomorrow - I have pile of chips on the table - sweet
stuste1: will eagerly await the video
yes - I am happy
what did you make?
a test part of my design
moves full rotary motion of both rotary axes while cutting a surface with the bottom of a cutter
how did you program it>>
its a shame the cinci can't tilt 90 degrees
it would be need to see that ball thing we made at the workshop in metal
i just sat thru 3 more days of catia brainwashing
I drilled and end milled holes - from different directions to see how accurate positioning is from different directions
yes - 90 degrees would be nice
how close can you get??
The cinci has 50 degrees on each of the rotary axes - A and B
usually you can hit it from 1 side of the trunnion only
A and B heads - not tables
the tool tilts
50 deg. is a profiling head for a virtical
it was never designed for it.... no strength in the column in those axes
we will have to wait for the viper to be able to cut the ball (from the workshop)
Dmess: this kind of head http://www.craftsmanshipmuseum.com/images/SpielCin1.JPG
but not on a bridge
this is the size cinci calls a 30V
this is cool: http://www.craftsmanshipmuseum.com/images/SpielCin5.JPG
[22:29:35] <jmkasunich> http://www.craftsmanshipmuseum.com/images/SpielCin2.JPG
[22:29:47] <jmkasunich> http://www.craftsmanshipmuseum.com/images/SpielCin3.JPG
stuste1: what size is your cinci?
if that last one has a scaled control on it someone needs a slap
the cinci is X122 Y42 Z14 - a hydrotel retrofit with the profiling head
is the head the same as the 30V, just on a different base/column?
found this pic of a 20V: http://www.roberts-eng.com/yahoo_site_admin/assets/images/IM001914.182170746_std.jpg
that looks more like yours
no, I take that back
that's what I understand - later they made 20V heads and put them on verticals
that one has Y on the table
Yes - that looks like the 20V-120 - the head is just a little smaller than the head on my machine - the frame is narrower and thinner
talk to you later - I am going home
goodnight as well
good evening (from home)
must be supper time for everyone
if you want to look at it. The gcode file to cut the part on the cinci is this file: http://www.mpm1.com:8080/cinci/cincitest.pu1
- the .igs files in the same directory are models of the part - the .u file is a unibase (database) file used by NCL. The .pp file is the part program that runs in NCL to create the .cl file. The post processor uses the .cl file to create the .pu1 (gcode) and .pr1 (report). Have fun.
