[00:27:49] <giacus> what is clarrion ? a language ?
[00:27:50] <m1ke_l> oh...wrong "emc"
[00:27:52] <m1ke_l> sorry.
[00:27:54] <jmkasunich> and what is rh4? do you mean read hat 4
[00:27:55] <giacus> hehe
[00:27:59] <jmkasunich> no prob
[00:28:07] <jmkasunich> this is for a linux based CNC controller
[00:28:08] <m1ke_l> sorry to wake you
[00:28:14] <jmkasunich> wasn't sleeping
[00:28:15] <m1ke_l> i just read header
[00:28:19] <jmkasunich> its only 8pm here
[00:28:34] <m1ke_l> its 8 here too
[00:28:38] <m1ke_l> maybe we are neighbors
[00:28:52] <jmkasunich> its a big timezone
[00:28:57] <giacus> 2:28 here
[00:29:25] <giacus> m1ke_l: what's Clarrion ?
[00:29:32] <m1ke_l> EMC Storage array
[00:29:36] <m1ke_l> a SAN
[00:30:02] <tomp> another meaning of emc
[00:30:15] <giacus> fisrt time I heard that
[00:30:26] <giacus> I remember an old language called Clarion
[00:30:29] <giacus> maybe ..
[00:30:38] <giacus> many years ago
[00:30:46] <tomp> here, emc is the Enhanced Machine Control
[00:30:48] <giacus> was a dbase language I think
[00:31:28] <giacus> tomp: are you from australia ?
[00:31:40] <tomp> chicago, australia :-)
[00:31:48] <giacus> wow
[00:32:01] <giacus> http://www.softvelocity.com/clarion/language_compilers.htm
[00:32:11] <giacus> was that
[00:34:03] <tomp> g'nite all
[00:34:56] <giacus> jmkasunich: is emc a registered trademark ?
[00:35:03] <jmkasunich> no idea
[00:35:12] <giacus> http://www.zibiz.com/solutions/storage-emc/index.html
[00:38:50] <jmkasunich> yeah, definitely the wrong emc ;-)
[00:38:51] <m1ke_l> tahts the one.
[00:40:31] <giacus> ........

[00:42:37] <giacus> * giacus switch to #linuxcnc
[01:24:49] <giacus> night
[02:03:18] <jepler> eew. qbasic? http://www.makezine.com/blog/archive/2006/04/homemade_computerized_embroide.html?CMP=OTC-0D6B48984890
[02:03:57] <jmkasunich> hey, whats wrong with qbasic?
[02:04:24] <jepler> maybe it's just fine .. I never wrote many BASIC programs on DOS
[02:04:31] <jepler> I think I stole a copy of TurboC or something
[02:04:55] <jmkasunich> I learned to program doing basic on a trs-80
[02:04:56] <jepler> * jepler tries to remember.
[02:05:23] <jepler> I did years of basic .. just not after I got rid of my Commodore
[02:05:26] <cradek> that's actually pretty cool
[02:05:32] <jepler> ("got rid of" meaning "put in a box in the basement", of course)
[02:05:35] <jmkasunich> the sewing machine
[02:05:38] <jmkasunich> ?
[02:05:54] <jmkasunich> I still have my kapro 2, in the bedroom closet
[02:05:57] <cradek> game port??
[02:06:47] <jepler> for analog feedback?
[02:06:52] <jmkasunich> for command
[02:07:05] <jepler> http://www.webcom.com/sknkwrks/embroidr.jpg
[02:07:12] <jmkasunich> it doesn't use g-code or any other language to describe the design
[02:07:15] <jmkasunich> it follows lines on paper
[02:08:44] <jmkasunich> Be sure window light and the
[02:08:44] <jmkasunich> room lights don't change during embroidering.
[02:08:50] <jmkasunich> ;-)
[02:18:17] <jmkasunich> those folks are nuts
[02:18:42] <jmkasunich> mixing homemade "report mix" in a rock tumbler
[02:18:51] <jmkasunich> The tumbler is on a long extension cord and is plugged
[02:18:51] <jmkasunich> in remotely. So far we have had no disasters.
[02:18:58] <jmkasunich> so far....
[02:19:26] <jepler> What is "report mix"?
[02:19:57] <jmkasunich> the explosive used to make the loud bang (report) in fireworks
[02:21:50] <jepler> oh!
[02:22:05] <cradek> that sounds like an incredibly bad idea
[02:22:10] <jmkasunich> yeah
[02:22:36] <jepler> http://hackedgadgets.com/2006/04/08/cathode-ray-tube-pocket-watch/
[02:23:21] <jmkasunich> don't let cradek see that
[02:23:53] <jmkasunich> A long time ago I made a 9V transistor battery that flashed
[02:24:00] <cradek> oh I've seen it
[02:24:18] <jmkasunich> alkaline 9V batteries have 6 tiny cells inside (AAAA?)
[02:24:21] <cradek> that's the scope clock guy
[02:24:32] <cradek> he's a nut, I like his clock a lot
[02:24:59] <jmkasunich> took out 2 or 4, don't recall now, and I replaced them with a blinker ckt and an led that would run on the remaining two cells
[02:25:02] <jepler> cradek: I hadn't seen the "pocket size" version
[02:25:30] <cradek> jepler: I think he intended to make a run of them - don't think he ever did, just the prototype
[02:25:57] <cradek> * SC100 Scope Clock in wood case - $400 assembled $350 kit
[02:26:03] <cradek> * SC60 Scope Pocket Watch estimated price - $700-1000 assembled
[02:27:59] <jmkasunich> you gotta want one pretty bad
[02:28:05] <jmkasunich> to pay that much
[02:28:40] <cradek> sigh, his scope clock is discontinued (used up his run of specially-made power transformers)
[02:29:10] <cradek> yeah I always wanted a scope clock, but I didn't want to pay even $350
[02:30:02] <jmkasunich> hmm, homemade tig welder
[02:34:12] <jepler> http://www.engadget.com/2004/09/17/the-wonderful-shot-tomys-digital-camera-for-dogs
[02:38:10] <jmkasunich> lol
[02:38:40] <jmkasunich> theres been times when I wanted a camera to take pics _of_ the dog, but not from the dog
[02:39:08] <jmkasunich> (we had a dog that would wait until we left for work, then get up on the table and steal catfood
[02:41:50] <jepler> our cats understand that it's only forbidden to get up on the counter when there's someone to see them actually make the jump.
[02:42:08] <jmkasunich> we have two
[02:42:24] <jmkasunich> one is too fat, we feed him on the floor and he gulps it down so the dog doesn't get it
[02:42:38] <jmkasunich> the other is a browser, her food is on a table
[02:43:14] <jepler> 'night
[02:43:26] <jmkasunich> goodnight
[02:45:30] <Jymmm> sigh... http://www.rockler.com/product.cfm?page=6064
[02:46:05] <jmkasunich> jymmm: did you see my comments earlier?
[02:46:12] <Jymmm> no
[02:46:18] <jmkasunich> (right after you signed on, maybe you weren't actually there)
[02:46:57] <Jymmm> looking....
[02:48:25] <Jymmm> jmkasunich: Can I have the drill you drew? Looks likes like something from Buck Rodgers! =)
[02:48:58] <Jymmm> A ray gun drill!
[02:49:39] <jmkasunich> what do you think of the idea?
[02:49:49] <jmkasunich> comes off the saw with two bolts to store...
[02:50:09] <jmkasunich> adjust height with blocks and a wedge under the unhinged edge of the board
[02:50:28] <Jymmm> The idea is great, but you're thinkingI have a saw that's worth anything =)
[02:51:07] <jmkasunich> alternatively, if you don't adjust much, use two pieces of aluminum square, one on each side, and rigidly fasten the board with screws to the bottom of the square tubes, use washers to space it for height
[02:51:15] <Jymmm> I like that back end of it, easy way to adj the drill height.
[02:52:37] <jmkasunich> figuring out how to fasten the drill down and keep it precisely square is gonna be fun
[02:52:45] <jmkasunich> most have lumpy shapes
[02:53:03] <Jymmm> insta-foam the bastard!
[02:53:49] <Jymmm> This is a good idea... http://sawdustmaking.com/Sheet%20Rack/rack.htm
[02:54:02] <jmkasunich> the secret to keeping it simple is not to try moving the drill inward to drill, move the wood instead
[02:56:52] <Jymmm> Stopped by HD today, no sanding disc thing to use in a drill. gonna have to get some aluminum and make some discs
[06:56:53] <etla> anyone know how to reverse the direction of an axis in emc2 ??
[07:04:23] <Jymmm> from the kybd when jogging -or- it's going left when it shouel be going right?
[07:05:22] <Jymmm> ENGINEERING REFERENCE MATERIAL: http://www.engineersedge.com/
[07:05:26] <Jymmm> ~~~~~
[07:26:56] <fenn> etla put a - before INPUT_SCALE
[07:27:55] <fenn> oh why do they always leave immediately
[07:43:01] <Jymmm> you're scarring them =)
[07:43:21] <Jymmm> was it you that suggested that $40 oxy-propane torch?
[07:44:28] <Jymmm> fenn was it you that suggested that $40 oxy-propane torch?
[08:10:51] <fenn> yeah why
[08:27:36] <Jymmm> fenn: Just wanted to say thanks for that... Found one at the flea market today for $3
[08:46:00] <fenn> thats pretty cheap yes
[08:46:30] <fenn> * fenn struggles with an avr programmer.. how pathetic
[08:59:36] <Jymmm> why pathetic?
[09:38:40] <giacus> morning
[09:39:47] <giacus> huh, it seems bush would use nuclear bombs now to attack iran..
[09:39:50] <giacus> nice
[09:40:27] <giacus> wait until tomorrow to know if berlusconi go home
[09:40:38] <giacus> elections day here :P
[09:45:39] <alex_joni> morning giacus
[09:45:43] <alex_joni> tough decision ;)
[09:45:49] <giacus> hello alex_joni
[09:46:58] <giacus> we hope so ..
[09:47:10] <alex_joni> I mean a hard decision
[09:47:24] <giacus> for ?
[09:47:59] <giacus> iran attack ?
[09:48:32] <alex_joni> no, for your election
[09:48:52] <giacus> well, its really hard
[09:49:13] <giacus> 40 millions of peoples whatching trash tv ..
[09:49:38] <giacus> they don't know nothing about freedom
[09:52:33] <alex_joni> well.. don't see an real alternative..
[09:53:20] <giacus> new generations should learn more about the story
[09:53:39] <giacus> same thing happen in computers
[09:53:57] <giacus> who want to know the story should read -> back
[09:54:07] <giacus> and learn how internet was born
[09:54:24] <giacus> not just use visual basic ..
[09:55:13] <giacus> so, new generations seems have no idea of what a nuclear attack mean
[09:55:26] <giacus> or a pseudo-democracy mean
[09:55:35] <giacus> thats the problem
[09:56:03] <giacus> they forgot the story
[09:56:13] <giacus> or they never learn that
[09:56:45] <giacus> then the past do not teach anything
[09:57:22] <giacus> and we are drived by these crazy peoples
[09:58:32] <giacus> the only messages they are able to receive are based upon trash
[09:58:42] <giacus> fast and trash messages like a tv spot
[10:03:20] <giacus> just wait until tomorrow to know if they will damage the country for 5 years more..
[10:06:02] <giacus> http://www.beppegrillo.it/eng/2006/04/basta_enough.html#comments
[10:32:33] <anonimasu> hm
[10:45:44] <fenn> heh i love how he calls everyone communist
[10:48:28] <giacus> fenn: :-)
[10:48:33] <giacus> timeout ..
[10:48:46] <giacus> * giacus goes to sack berlusca
[10:48:48] <giacus> later
[10:48:58] <giacus> giacus is now known as giacus_afk
[11:56:57] <alex_joni> hiya fenn
[11:57:02] <alex_joni> fenn: seen this? http://www.bwired.nl/
[12:34:18] <fenn> is this like internet zero?
[12:35:13] <fenn> oo i like the doorbell cam
[12:41:17] <alex_joni> http://hackedgadgets.com/category/complex-hacks/
[12:43:46] <alex_joni> man, there are quite some crazy people out there
[12:44:19] <anonimasu> check the big dog video
[12:44:27] <alex_joni> http://hackedgadgets.com/2006/01/10/crazy-go-carts/
[12:45:38] <anonimasu> the swimming snake robot is sweet
[12:46:00] <alex_joni> yeah
[12:46:03] <anonimasu> too bad it's in japanese ^_^
[12:47:24] <alex_joni> http://hackedgadgets.com/category/crazy-hacks/page/2/
[12:48:55] <anonimasu> hm
[12:49:02] <anonimasu> makes you really feel like building robots ;)
[12:50:13] <alex_joni> seen stanley?
[12:50:17] <anonimasu> stanley?
[12:51:09] <alex_joni> yup :D
[12:51:20] <alex_joni> http://hackedgadgets.com/2006/01/08/stanley-winner-of-the-darpa-grand-challenge-2005/
[12:52:17] <anonimasu> check the air engine
[12:52:22] <anonimasu> http://home.ctlnet.com/%7Erobotguy67/classic_cars/air_engines/V-Twin/air_engines.htm
[12:53:08] <anonimasu> CUTE
[12:53:10] <anonimasu> err..
[12:53:12] <anonimasu> cute stuff
[12:53:34] <anonimasu> alex_joni: had it in a new tab already ;)
[12:55:00] <fenn> hm winning the darpa grand challenge isnt exactly a hack
[12:55:09] <anonimasu> yeah more of a accomplishment
[12:55:15] <anonimasu> I am kind of curious
[12:55:19] <anonimasu> do they get a map where they should go?
[12:55:29] <alex_joni> http://hackedgadgets.com/2006/02/04/build-a-stun-gun/
[12:55:31] <alex_joni> LOL
[12:55:38] <anonimasu> or a wayoint and a topology map ?
[12:55:41] <alex_joni> anonimasu: yes and no, they get GPS checkpoints
[12:55:47] <alex_joni> and topology/roadmaps
[12:55:50] <anonimasu> ah
[12:55:51] <anonimasu> sweet
[12:56:06] <alex_joni> yeah, it was THE major event in the last two years ;)
[12:56:17] <fenn> i think they should make the robots figure it out
[12:56:21] <fenn> gps is totally cheating
[12:56:40] <anonimasu> yep
[12:56:47] <anonimasu> topology and a final waypoint ;)
[12:57:11] <anonimasu> get there.
[12:57:12] <anonimasu> ;)
[12:57:22] <fenn> heh gotta have a payload too
[12:57:22] <anonimasu> still very cool
[12:57:31] <fenn> otherwise my $20 model airplane could do it
[12:57:58] <fenn> get there and don't get shot by our team of snipers
[12:58:35] <anonimasu> hehe
[13:00:16] <anonimasu> ouch my stomach hurts..
[13:00:25] <anonimasu> I ate too many of theese crackers with garlic cheese on them
[13:00:29] <alex_joni> lol
[13:01:21] <rayh> making me hungry already.
[13:01:46] <alex_joni> * alex_joni ate lots of salad today ;)
[13:01:54] <anonimasu> hm, *curious about thoose topology maps*
[13:04:11] <alex_joni> anonimasu: ever tried to forward a rs232 port over ethernet?
[13:04:19] <alex_joni> wonder if there are any standard tools out there..
[13:04:29] <anonimasu> heh
[13:04:30] <anonimasu> ye
[13:04:31] <anonimasu> s
[13:04:36] <alex_joni> * alex_joni wants to use a linux-serial & eth forwarded to a doze box
[13:04:50] <anonimasu> hm a moment
[13:04:57] <alex_joni> I want to admin my Switch ;)
[13:05:19] <anonimasu> "realterm"
[13:05:41] <anonimasu> http://realterm.sourceforge.net/
[13:06:07] <alex_joni> * alex_joni looks
[13:06:15] <anonimasu> although I dont know if that'll run on linux
[13:06:32] <anonimasu> that'll allow you to do rs323 over tcp
[13:06:53] <fenn> cant you just pipe ckermit over ssh?
[13:07:00] <fenn> or am i thinking backwards
[13:07:28] <alex_joni> hmm.. not quite what I want
[13:07:38] <alex_joni> I want a virtual RS232 driver on the doze part
[13:07:48] <alex_joni> and on the other end have a linux server with the rs232 port
[13:08:06] <alex_joni> I think telnet on the linux side is ok
[13:08:15] <rayh> * rayh just shakes his head.
[13:10:07] <fenn> * fenn agrees with rayh
[13:11:43] <rayh> Hi fenn
[13:12:06] <fenn> alo
[13:15:56] <alex_joni> anonimasu: something like this: http://www.network-serial-port.com/nspk-data/nspk-scr.gif
[13:16:43] <fenn> looks like you'd have to write some code/buy some software
[13:16:50] <fenn> if they're selling a product
[13:19:30] <alex_joni> fenn: yeah, for that solution.. but I just started looking ;)
[13:19:42] <alex_joni> found this though: http://sourceforge.net/projects/ser2net/
[13:36:52] <alex_joni> yay, found what I need : http://www.hw-group.com/products/hw_vsp/index_en.html
[13:37:33] <anonimasu> alex_joni: looking now
[13:37:54] <anonimasu> virtual serial port xp..
[13:37:55] <anonimasu> works..
[13:37:58] <anonimasu> but it's commercial
[13:38:58] <alex_joni> it's free
[13:39:08] <alex_joni> http://www.hw-group.com/products/hw_vsp/index_en.html#licence
[13:39:48] <anonimasu> ah that one yeah
[13:39:53] <anonimasu> nice
[13:39:54] <alex_joni> for distribution you need to put up a link to their website
[13:40:14] <fenn> seems like an ok deal to me
[13:40:24] <fenn> as far as doze goes at least
[13:40:28] <alex_joni> * alex_joni doesn't want to distribute it..
[13:40:35] <alex_joni> fenn: it uses as standard RFC
[13:40:41] <alex_joni> RFC 2217
[13:40:56] <alex_joni> found a few proxy's for linux that act according to RFC 2217
[13:41:07] <alex_joni> so I guess I'm set.. I hope
[13:56:43] <steves_logging> steves_logging is now known as steve_stallings
[14:19:27] <steve_stallings> steve_stallings is now known as steves_logging
[14:46:03] <EHJ-1> Alex: FYI, I just emailed to you the protocol I have so far defined for implementation independent remote host.
[14:47:15] <EHJ-1> I have a real simple prototype sort of working.
[15:28:31] <K4ts> giacus
[15:28:36] <K4ts> hello
[15:29:52] <Jymmm> * Jymmm kisses Anna and makes giacus jealous!
[15:30:29] <K4ts> Jymmm: giacus is forever afk
[15:30:45] <K4ts> :-(
[15:31:37] <Jymmm> K4ts: He's with his other 14 girlfriends
[15:31:48] <K4ts> ahha
[15:31:51] <Jymmm> =)
[15:49:44] <Bo^Dick> could someone tell me in what voltage range Vref the following design offers? http://www.pminmo.com/l297-8/L297_8HVschematic.pdf
[15:56:10] <jmkasunich> Bo^Dick: 5V is applied to a voltage divider consisting of a 2.7K resistor and a 1K pot
[15:56:24] <jmkasunich> calculate the voltage at the top of the pot, the range is from there to zero
[15:57:01] <jmkasunich> it will be modified somewhat if the L297 loads it down, check your L297 data sheet to see the input characteristics of the Vref pin
[15:58:27] <jmkasunich> if the input impedande of the L297 is less than 100K or so you need to do the voltage divider calcs assuming that the Zin is in parallel with the 1K pot
[15:59:45] <Bo^Dick> ok thx
[16:00:43] <Bo^Dick> btw, besides that, could you come up with an idea on how one could lower that voltage level by 29.3% on a digital command with the aid of an open collector and-gate?
[16:01:01] <jmkasunich> yes
[16:01:15] <jmkasunich> its not hard, think voltage dividers and parallel resistors
[16:01:24] <jmkasunich> the details are left as an exercise for the student
[16:06:37] <CIA-8> 03jmkasunich 07HEAD * 10emc2/configs/sim/ (servo_sim.hal servo_sim.ini): added limit and home switches to the simulated servo configuration
[16:06:45] <Jymmm> jmkasunich: Just curious, do you know how most variable speed (cord/less) drills are made variable?
[16:07:10] <jmkasunich> corded use a triac or scr based circuit similar to a light dimmer
[16:07:18] <jmkasunich> cordless (DC powered) use PWM
[16:07:27] <jmkasunich> gotta go, going to a baseball game!
[16:07:36] <Jymmm> jmkasunich so the trigger is just a pot?
[16:07:43] <jmkasunich> yes
[16:07:54] <Jymmm> ok, cool. gives me an idea or two
[16:08:10] <jmkasunich> uh-oh!
[16:08:21] <jmkasunich> * jmkasunich hides from Jymmms idea
[16:08:43] <Jymmm> Nah, not THAT bad.
[16:09:01] <Jymmm> inexpensive solution
[16:30:38] <alex_joni> EHJ-1: still there?
[16:54:23] <Jymmm> what do you call a drill press spindle... a quill or soemthing?
[16:56:08] <rayh> Sure. Usually quill motion is distinct from Z or knee motion.
[16:56:51] <Jymmm> I'm trying to understand how a drillpress works in the respect of pull the bit down without the side binding.
[16:57:19] <Jymmm> without taking my drillpress apart that is =)
[16:59:32] <rayh> Ah. In bigger mills, the outside of the quill does not spin.
[16:59:58] <rayh> There are bearings inside that allow the shaft to rotate.
[17:00:35] <Jymmm> Ok, what about the lowering/rasiing of the chuck?
[17:01:47] <rayh> Just put a z slide on the gantry.
[17:03:32] <Jymmm> No, no, I mean a drill press, not a mill.
[17:06:32] <EHJ-1> Alex: I am now, wen to lunch
[17:06:45] <Jymmm> oh, a spline!
[17:08:48] <Jymmm> rayh: I guess I'm talking about #56 http://www.toolpartsdirect.com/images/schematics/blackdecker/1785_type_1.big.jpg
[17:09:24] <alex_joni> EHJ-1: got your email.. gotta say it all looks good
[17:09:30] <alex_joni> only one question remains
[17:09:30] <rayh> looko\ing
[17:09:31] <alex_joni> WHY?
[17:11:43] <EHJ-1> Per my questions to you earlier regarding setup, that the configurations, builds, etc. all need to match. I am attempting a configuration independent protocol between the CNC application and the user interface.
[17:11:53] <Jymmm> rayh #56 left side of image, middle
[17:14:35] <rayh> Yep. 56 is the rotating part 54 is the bearing housing.
[17:14:48] <rayh> 54 slides up and down.
[17:15:12] <Jymmm> 54 does? I thought 56 slides within 54
[17:15:36] <EHJ-1> Alex: I have a prototype I can send you if you like. I can send you a windows exe, I haven't figured out the linux distro yet.
[17:16:44] <rayh> The top part of 56 is a splined shaft that slides inside the drive pulley.
[17:17:45] <alex_joni> EHJ-1: no, I get it.. but I just don't understand why you need to add another layer
[17:18:09] <Jymmm> rayh: ok, on MY drill press, there is nothign the protrudes thru the middle of either pulley. Just a nut iirc
[17:18:30] <Jymmm> rayh like #65
[17:18:54] <Jymmm> top of image, below belt
[17:19:17] <Jymmm> (mine only has one belt, not two as shown here
[17:20:18] <rayh> Sure this has a center idler
[17:20:56] <rayh> But the top part of 56 is the sliding drive splines.
[17:21:51] <Jymmm> rayh to the spline part fits within the pulley?
[17:22:05] <EHJ-1> ALex: That way it makes it a lot easier to customize your own UI, especially on the windows platform without needing to know too much about EMC itself. All one needs to understand is the protocol, and even that can be wrapped into a single DLL. In the process not needing to load a version of TCL or Python or whatever on the windows box.
[17:22:16] <rayh> It's not real obvious but I think 61 is the outer part that slides on the spline
[17:23:00] <rayh> 36 is the pinion that drives 54 up and down.
[17:23:29] <Jymmm> rayh: Right, but I can't tell what it's engaging.... 54 or 56 or somethign else
[17:23:43] <alex_joni> EHJ-1: you don't need TCL nor Python to talk NML
[17:23:47] <alex_joni> just simple c++
[17:23:47] <Jymmm> so 56 is statioanry
[17:24:03] <alex_joni> EHJ-1: you simply need to copy emc2.hh & emc2.cc over, and use those
[17:24:08] <rayh> That is confusing. But I think 56 only rotates inside 54.
[17:24:20] <alex_joni> EHJ-1: along with rcslib.lib, and you can link your app..
[17:24:25] <rayh> and 54 slides in the case driven up or down by 36
[17:24:30] <alex_joni> EHJ-1: but if you find this easier .. ;)
[17:25:02] <Jymmm> rayh: Yeah, not hte best iamge... so is 69 stationary or the chuck?
[17:25:39] <rayh> (69 dude) Yep that's the chuck.
[17:25:42] <EHJ-1> But you do need to link in emc.cc and all that, and that has to be basically the same build and configuration, otherwise the size of the objects changes.
[17:26:03] <Jymmm> rayh : funky ass drawing of a chuck =)
[17:26:06] <alex_joni> EHJ-1: you only need emc2.hh & rcslib.lib
[17:26:22] <rayh> Hey it looks to me like lots of these parts are not to scale.
[17:26:27] <alex_joni> as you've seen the 3? year old rcslib.lib still works with a modern emc2
[17:26:34] <alex_joni> so most things haven't changed
[17:26:48] <rayh> 68 bolts to 69 or is threaded on.
[17:27:04] <rayh> 68 is the taper that locks into 56
[17:27:08] <alex_joni> EHJ-1: the size & all is defined in the emc2.hh, the NML library doesn't change
[17:27:28] <alex_joni> EHJ-1: but I agree if you never have done this before, it's not trivial to get it working..
[17:27:31] <rayh> Notice that both 56 and 54 have a side slot that needs to be alligned
[17:27:48] <alex_joni> EHJ-1: although xemc.cc should compile just fine under mingw I think
[17:27:58] <alex_joni> err... cygwin
[17:28:07] <rayh> so that the taper release tool 70 can be inserted and release 68
[17:28:57] <Jymmm> rayh: whats the photographs when ya need em! lol
[17:29:04] <EHJ-1> You mean emc.hh, right?
[17:29:33] <rayh> A good scaled drawing would make a lot more sense.
[17:30:19] <alex_joni> EHJ-1: right
[17:30:39] <alex_joni> EHJ-1: I planned to change that with paul a while back, but we never did finished it
[17:32:37] <Jymmm> rayh Yeah, or some cross cut photos =)
[17:32:46] <EHJ-1> Alex: Yea, and that has a bunch of dependencies on other files (config, rcs, cannon, etc.). All of which has to get built in and has to match the build and it seems the configuration including ini files, etc. on the "server".
[17:33:12] <rayh> That would be nice.
[17:33:34] <alex_joni> EHJ-1: yes
[17:34:33] <EHJ-1> Right, ideally I want my UI to only need to know IP address and socket number, and the configure itself based on what the "server" reports as its configuration.
[17:34:51] <EHJ-1> then^
[17:37:03] <rayh> EHJ-1, How is this different from the current emcserver?
[17:37:36] <alex_joni> rayh: it doesn't talk NML, but some other protocol using a standard socket
[17:38:16] <rayh> Okay. Why would another protocol be prefered?
[17:38:48] <alex_joni> rayh: working with NML means some coding overhead to build the stuff
[17:39:03] <alex_joni> for someone who never touched it, it's easier to set up something new
[17:39:08] <EHJ-1> What seems to be passed in the current implementation is a streem of C++ objects, where the receiving side has to exactly match the sending side as far a build and even configuration.
[17:39:21] <EHJ-1> stream
[17:39:36] <rayh> Sure that sounds like NML.
[17:39:51] <alex_joni> rayh: he is talking about NML
[17:39:59] <rayh> What we have done is compile emcsh for the gui's target OS
[17:40:12] <alex_joni> rayh: in case the GUI is tcl, yes
[17:40:36] <alex_joni> if you want native GUI's you need to compile libnml or rcslib for the target OS
[17:40:49] <alex_joni> then also the recent emc.cc & emc.hh & other related stuff
[17:40:58] <rayh> Or modify emcsh for the native.
[17:41:13] <alex_joni> so the problem is that you always will need to have synced versions of GUI & emc
[17:41:18] <alex_joni> or else they won't agree
[17:41:26] <alex_joni> but I think that's true for ANY protocol
[17:41:36] <alex_joni> once the protocol changes.. you need to change both sides
[17:41:54] <rayh> Hey. Even with all the changes to canon, the emcsh library has been fairly static.
[17:42:09] <EHJ-1> Alex: Not at all. There are plenty of protocols which don't change or know how to adapt to change.
[17:42:54] <EHJ-1> I based my protocol (very simplistically of course) on SMTP and cisco server protocols.
[17:43:29] <EHJ-1> I just use two "l"s in hello. :)
[17:50:01] <alex_joni> EHJ-1: well, I'm not gonna talk you out of this.. it's just not what I would do..
[17:51:31] <EHJ-1> I show it to you when I get it working. Maybe you will change your mind. :)
[17:58:01] <alex_joni> what matters is the GUI, the way it talks to emc is irelevant for the user
[18:01:13] <anonimasu> hm

[19:41:02] <skunkworks> Hi steve
[19:52:13] <K4ts> hello
[19:52:23] <giacus> ciao
[19:52:48] <K4ts> Jymmm: giacus is present wowwwwww
[19:53:05] <giacus> i was present also before ..
[19:53:08] <Bo^Dick> is it true that this design for Vref allows a maximum reference voltage Vref to just around 1.3V? (datasheet states 3V max) http://www.pminmo.com/l297-8/L297_8HVschematic.pdf
[19:53:23] <giacus> :)
[19:56:04] <jepler> Bo^Dick: How high does the reference voltage need to be to permit the maximum L298 current? The sense resistors (R9, R10) seem to be .5ohm, and the maximum current is 2A per bridge.
[19:56:50] <K4ts> giacus kira sleep
[19:56:57] <giacus> nice
[19:57:19] <giacus> you not ?

[20:00:39] <K4ts> cosa hai deciso
[20:00:54] <K4ts> per pasqua quando sali?
[20:01:16] <giacus> what ?
[20:02:00] <jepler> huh. The pminmo design has RC filter on the sense inputs of the L298, but st.com suggests that they are unneeded (http://www.st.com/stonline/products/literature/an/1679.pdf figure 15)

[20:42:58] <skunkworks> alex - what was your first computer?
[20:43:44] <giacus> skunkworks: looking for an old computer ? :)
[20:44:05] <skunkworks> no :)
[20:44:20] <alex_joni> skunkworks: spectrum
[20:44:24] <skunkworks> my first was a TI 99/4a
[20:45:06] <alex_joni> I remember playing a lot of harrier &
[20:45:37] <giacus> texas instruments ?
[20:45:46] <giacus> was a computer or a calculator ?
[20:46:04] <skunkworks> computer
[20:46:07] <skunkworks> yes
[20:46:13] <giacus> never heard

[20:48:42] <giacus> fisrt computer I bought was a vic20 as jepler ..
[20:49:05] <giacus> some year after I switched to C64
[20:49:15] <skunkworks> our next computer was C128
[20:49:21] <giacus> never used
[20:49:36] <giacus> after it the next has been 386sx
[20:49:39] <skunkworks> we used it mostly in c64 mode ;)
[20:49:40] <giacus> and dos
[20:49:56] <giacus> 486 windows 3.1
[20:50:17] <giacus> and in the 1996 I discovered Debian potato
[20:50:45] <giacus> I dont know of any 'personal' computer before the vic 20
[20:51:13] <giacus> i'm 38 years old
[20:51:14] <skunkworks> timex sinclare - was that before the vic20?
[20:51:22] <giacus> dont know you :)
[20:51:31] <skunkworks> 32 I think
[20:51:53] <giacus> the zx sinclair was born at bit after the vic20
[20:52:06] <giacus> some year I think ..
[20:52:09] <skunkworks> cousin had that
[20:52:23] <giacus> I already have the C64 here
[20:52:31] <skunkworks> our first "pc" was a 386sx
[20:52:48] <giacus> win 3.1 ?
[20:53:28] <giacus> oh.. I also remember before win 3.1
[20:53:39] <giacus> there were nice apple computers
[20:53:40] <skunkworks> you know - I don't think so. I remeber using the dos menu program of some sort
[20:54:03] <giacus> as well, you know how bill 'taked' from xerox and apple ..
[20:54:18] <skunkworks> played a lot of chuck yeagers flight simulator
[20:54:25] <giacus> first GUI was by apple computers
[20:54:36] <giacus> MC Intosh
[20:54:52] <skunkworks> did you see you can run xp on macs now?
[20:54:53] <giacus> they invented the mouse
[20:55:04] <skunkworks> they as in xerox
[20:55:08] <giacus> with qemu ?
[20:55:25] <giacus> i'd not be interested in run xp in apple ..
[20:55:27] <giacus> not
[20:55:32] <skunkworks> ;)
[20:55:37] <giacus> make no sense
[20:55:50] <alex_joni> good night all
[20:55:55] <alex_joni> * alex_joni goes to bed
[20:55:55] <giacus> night alex_joni
[20:56:03] <skunkworks> night alex
[20:57:09] <giacus> the hardware I like in the past was sun spark machine
[20:57:28] <alex_joni> you can bang two stones together for sparks
[20:57:31] <giacus> used a lot for stable and secure systems as firewall
[20:57:51] <giacus> strong machine
[20:58:46] <giacus> what I never seen or tried is transmeta instead
[20:59:41] <skunkworks> did you play a lot of games on the c64?
[20:59:54] <giacus> yeah, a lot really ..
[21:00:08] <skunkworks> that is mostly what I had used it for. Beach head?
[21:00:14] <giacus> there' some c64 emulator online too
[21:00:39] <giacus> can't remember titles
[21:00:41] <skunkworks> I have played with them. there are also ti99/4a emulators
[21:01:02] <skunkworks> people have way to much time on their hands ;)
[21:02:32] <jepler> "vice" is the commodore emulator I use
[21:02:35] <giacus> basic for a stupid language for what I remember
[21:02:36] <jepler> I replayed Ultima I the othre day
[21:02:58] <giacus> Dbase III plus and clipper was nice
[21:03:17] <giacus> CA clipper
[21:03:40] <giacus> it was using C libs
[21:04:03] <giacus> and interfacing database from dos
[21:04:11] <giacus> created with Dbase
[21:04:23] <giacus> was very stable
[21:04:37] <giacus> first dos vers. was nice
[21:04:47] <skunkworks> I have a programmer at work that used to program clipper. Still has one company he helps out (still running clipper)
[21:05:10] <giacus> he use clipper yet ?
[21:05:32] <skunkworks> yes - to help his client out. it is a payrol program of some sort
[21:05:56] <giacus> uhm ..
[21:06:20] <skunkworks> jepler: vice is what I had used.
[21:06:42] <giacus> I spent 2-3 years playng around borland delphi too
[21:06:59] <giacus> 700 $ for Deplhi 2 :(���
[21:07:18] <skunkworks> is still have borland C++ around here on 24 floppy disks ;)
[21:07:37] <giacus> after few years was obsolete
[21:07:51] <giacus> with incompatibles libs
[21:08:15] <giacus> next step was to switch to Linux
[21:09:38] <giacus> the cost for the delphi upgrade was around $ 400
[21:10:55] <giacus> hello TorbaX
[21:12:44] <TorbaX> hello giacus
[21:12:46] <Bo^Dick> * Bo^Dick is back
[21:12:59] <giacus> any progress with your cnc ?
[21:13:18] <Bo^Dick> jepler: hmmm. i didn't consider that.
[21:13:51] <Bo^Dick> jepler: that makes sense of course. however i hoped the max current was 2.5 amps
[21:14:51] <giacus> Bo^Dick: l298 ?
[21:15:57] <giacus> I think they can be coupled to get double current
[21:16:02] <giacus> 4 A
[21:20:38] <Bo^Dick> yes they can be coupled. however i think 2.5 amps is enough for me
[21:20:47] <giacus> Bo^Dick: i'm not expert in electronic, but take a look to this javascript:openreq('http://www.ortodoxism.ro/datasheets/SGSThomsonMicroelectronics/mXtvsqy.pdf')
[21:21:22] <giacus> http://www.datasheetcatalog.com/datasheets_pdf/L/6/2/0/L6203.shtml
[21:21:48] <giacus> the L6203
[21:27:07] <giacus> should be a nice IC for a stepper driver
[21:29:14] <giacus> http://engraving.majosoft.com/html/body_stepper_driver_board_with_l297_and_L6203.html
[21:30:18] <giacus> looks compact, without lot of components around
[21:32:09] <giacus> I could find 4A motors for the same price of 2A here around
[21:32:14] <jepler> single sided board design? nice.
[21:32:23] <giacus> and maybe it could be better to prevent lost steps
[21:32:33] <jepler> "I don't have tested this board !"
[21:32:38] <giacus> jepler: yeah, seems nice
[21:33:46] <giacus> yeah seen ..
[21:34:09] <giacus> inputs are the same of l298 I think
[21:36:12] <CIA-8> 03cradek 07v2_0_branch * 10emc2/tcl/tkemc.tcl: remove debug output
[21:49:30] <Bo^Dick> btw, there is no statement about the impedance of the Vref pin on the L297. do you think it could be treated as very high impedance (>100K)?
[21:52:10] <Bo^Dick> it would be an advantage if the current drawn by that pin is neiglible
[22:03:31] <TorbaX> TorbaX is now known as TorbaX_away
