00:11 katsmeow-afk $350,000 Rolls Royce , 650hp, 0-60 is 4.5 seconds
00:19 katsmeow-afk i didn;t set out to be repairing scopes tonite, but two are now working again, and i am chasing problems in the 3rd,,, but if i set up another desk upstairs for scope repairs, i'm going to take a break for a while
00:25 katsmeow-afk humans : http://starcasm.net/archives/257233
00:28 rue_house ok I'm back from work again
00:28 katsmeow-afk are you???
00:29 rue_house yea
00:29 rue_house working at the hospital, it really helps to get things done when there is nobody there
00:30 tsmeow-afk sips ramen with actual fish added t
00:31 rue_house hmmm, I need to solve the supper problem
00:31 katsmeow-afk good luck, i cannot get awintel box toturn on the microwave, let alone putting the food into it first
00:33 katsmeow-afk i bet you no one in #robotics can tell their puter to nuke a slice of cherry pie, add ice cream to the plate, and bring it to them, even tho there's robotics parts all over t the place, and voice recognition too
00:34 rue_house I have knock recognition
00:34 rue_house I have code that will detect 4 different patterns
00:34 rue_house and it can be expanded to more
00:34 katsmeow-afk but i have been on irc since 1996, and i am still waiting on the pie
00:35 rue_house pie?
00:35 katsmeow-afk [00:18] <katsmeow-afk> i bet you no one in #robotics can tell their puter to nuke a slice of cherry pie, add ice cream to the plate, and bring it to them, even tho there's robotics parts all over t the place, and voice recognition too
00:40 rue_house I agreed by not saying anything
00:41 katsmeow-afk o
00:48 katsmeow-afk <cough>
00:50 rue_house I still cant find a 3 conductor 30A 250V twistlock
00:50 rue_house for les than what they cost here, which is like $50
00:50 rue_house female cord end
00:50 katsmeow-afk yeowch
00:51 katsmeow-afk consider the 4-poles?
00:51 rue_house no I already have the 3 pole on my welder, and 4 poles are more
00:51 katsmeow-afk o
00:53 katsmeow-afk http://www.homedepot.com/p/Pass-Seymour-30-Amp-125-250-Volt-Grounding-Plug-L1430PCCV3/202525691
00:53 rue_house ah! home depot
00:53 katsmeow-afk http://www.homedepot.com/p/Pass-Seymour-30-Amp-250-Volt-Locking-Plug-L630PCCV3/100114938
00:56 rue_house http://www.homedepot.com/p/Pass-Seymour-Turnlok-30-Amp-250-Volt-Connector-L630CCCV3/202039718#
00:57 katsmeow-afk oh, you want the female end
00:57 rue_house yea
00:57 rue_house pretty sure thats it
00:57 katsmeow-afk well, now you have urls for both :-)
00:58 katsmeow-afk now whatcha do is poke those Seymour numbers into ebay
00:58 rue_house turnlok was enough
00:59 katsmeow-afk ok
01:00 katsmeow-afk yeas, $7.20 on ebay, free s&h
01:00 katsmeow-afk you're welcome :-P
01:01 katsmeow-afk i can't tell about http://www.ebay.com/itm/Pass-Seymour-Turnlok-Connector-15999-/360222418131
01:01 katsmeow-afk http://www.ebay.com/itm/Pass-Seymour-L5-20C-Turnlok-Female-Plug-/390588899424 says it's a 20amp
01:02 rue_house they all seem to be out of usa, I dont know if I can get it without duty fees
01:03 rue_house iamturni1,
01:03 rue_house iamturni1,
01:03 katsmeow-afk ya know the 20 is a smaller diameter circle than the 30?
01:04 rue_house its a 250V 30A
01:04 katsmeow-afk k, there's a lot of look-alikes on ebay saying they are 20
01:04 rue_house the prongs are reversed from the 120V, if you hack the connector, you can kinda make one from the other
01:04 katsmeow-afk and there is a 20amp twistlock, i forget it's looks tho
01:05 rue_house the different ones have the hook and the sizes re-arranged
01:05 rue_house I'v already got a buinch of these on stuff
01:05 rue_house I just need one more female to complete the tangled web
01:05 katsmeow-afk this one says 15amp : http://www.ebay.com/itm/2-New-In-Box-Pass-and-Seymour-L515-C-Turnlok-Connector-15AMP-/181295666367
01:05 rue_house again, its in the usa
01:06 katsmeow-afk Pass and Seymour L515-C Turnlok Connector 15AMP, 125V, 2-pole, 3watt. <<== 3 whole watts
01:06 rue_house watt, hahah way
01:08 rue_house you need to understand that if customs sees the package, I have to pay them $3 for it, and the broker charges $50 for brokering it
01:08 katsmeow-afk i could swear the L14-30 are even cheaper
01:08 rue_house L6-30
01:08 tsmeow-afk strolls over to Canadia and throws it at rue in a fit of rage and then runs like
01:09 rue_house :)
01:09 katsmeow-afk i am assuming there's no rage tax
01:09 rue_house maybe from the us side, not the canadian side
01:09 katsmeow-afk got that flying robot finished yet? can it carry,, oh, something about the weight of the item you want carried?
01:10 rue_house L6-30R
01:10 rue_house iamturni1,
01:10 tsmeow-afk wonders about the accuracy of the trebu
01:11 rue_house the drug runners would have a field day
01:13 katsmeow-afk http://www.ebay.com/itm/Pass-Seymour-Lot-of-3-Locking-Connectors/141154198697 <<== may not fit, but price averages $5.91 each to me
01:14 rue_house ok
01:14 rue_house I'm going to start an endevour that will prolly end up in me paying more than I sould for one at our electrical wholesaler
01:15 rue_house http://www.ebay.ca/itm/Replacement-30-Amp-250-Volt-Female-Twist-Lock-3-Wire-Power-Cord-Plug-Nema-L6-30P-/111095964776?pt=LH_DefaultDomain_0&hash=item19ddd5e468
01:17 katsmeow-afk yeas, those are the "made in china" ones, not the "made in Mexico" ones we get here
01:17 rue_house funny enough I cant find any from china
01:17 katsmeow-afk may cost them too much to sip one at a time
01:18 rue_house aha, hahah
01:18 katsmeow-afk they ship "janet" a whole container of them for cheaper
01:18 rue_house http://www.aliexpress.com/item/Hubbell-HBL2623-NEMA-L6-30R-AC-Connector/553542639.html
01:18 rue_house huh
01:19 katsmeow-afk ouch
01:19 rue_house thats about what one costs me at the corner store here
02:14 katsmeow-afk what do you suppose it would cost to sink a 4" pneumatic tube line from China to Canadia?
02:15 katsmeow-afk it would prolly haveto go thru Japan too, and Alaska
08:39 katsmeow-afk well, no real axe, no relax
08:44 katsmeow-afk i have some resistors : blue-white-gold-black-brown , and they read 0.7 ohms or lower , what are they?
08:45 katsmeow-afk 697 ohms?
08:55 tsmeow-afk growls something about getting off her fat ass to sold someting and finds out the iron isn't plugged into the strip that's turne
08:55 katsmeow-afk solder
09:10 katsmeow-afk ok, another oscope is working, jumpered a bad pot with a couple resistors
09:11 katsmeow-afk well, it needs that 0.15 amp fuse, i have it ordered, there's a 3(?) or 0.3(?) amp fuse in it now, the fuse so thin i can barely see it
09:25 rue_house gold in the middle?
09:25 rue_house not blue white black gold brown?
09:25 rue_house the last brown would be 1%
09:25 rue_house 690*.01 ?
09:25 rue_house hmm
09:26 rue_house I think they should be 6.9R?
09:26 rue_house but I dont know how they do sub-1R with 1%
09:27 katsmeow-afk i may have the colors reversed
09:28 katsmeow-afk it's 1/4 watt metal foil resistor
09:28 katsmeow-afk anyhoo, the scope is in position to work on vic20/c64 !!
09:29 katsmeow-afk and the two 7603 i got working last nite, the ones with the spectrum analyser screens
09:29 rue_house cool
09:30 katsmeow-afk tis a pretty sight
09:30 rue_house hmm I'm gonna take this flourescent laght I have, thats junk, and regut it with leds...
09:31 katsmeow-afk i think one of the still-dead ones has psu issues, i may take my time and do an updated psu design in it, in such a way i can isolate and monitor each slot
09:31 rue_house cap problems?
09:32 katsmeow-afk you can get led-flourescent tubes , but they take a wile to come on because they still haveto deal with the oem ballast,, gutting it for all leds is the best idea
09:32 katsmeow-afk prolly
09:32 rue_house the ballast is crap, a good one costs $60
09:32 rue_house its eating bulbs
09:33 katsmeow-afk but, the entire +5 is dead, so it could be the 130v line, all the otehr psu bootstrap to the 130 or 50 or -50 lines
09:33 rue_house I'm running SO late...
09:33 katsmeow-afk it's a wierd design
09:33 rue_house didn't wake up to my alarm
09:33 katsmeow-afk leds will cost you under $60
09:33 rue_house yea
09:33 katsmeow-afk and run cooler
09:33 katsmeow-afk and be dimmable
09:33 katsmeow-afk and lighter
09:34 katsmeow-afk and won't hum,, if you string them in series for a rectified powerline voltage
09:34 rue_house oo didn't think to put in a dimmer, cool stuff
09:36 katsmeow-afk i put a metal edge on the front of the new shelf, it's already dinged up by moving the scopes around
09:37 katsmeow-afk good thing is, these new shelves can hold a lot of weight effortlessly, i prooved that the last 24hrs
09:37 rue_house were you climbing?
09:37 rue_house wow
09:37 rue_house the 10m led strips are on large spools
09:38 katsmeow-afk no, but there's 7 mainframe scopes on it
09:38 rue_house yike
09:39 katsmeow-afk on one shelf atm, there's 2 stacked on one end, and 2 stacked on the othe end, and it's a 6ft long shelf, no middle supports
09:39 katsmeow-afk that's sitting on the bottom shelf, and the bottom shelf has a mainframe at each end of it too
09:39 rue_house I work out 2W of lighting should do
09:39 katsmeow-afk i could take a pic.....
09:39 rue_house I wonder if this means I can use a 5V 2A adapter
09:40 rue_house 4V (2 whites?) at 300mA + 1V drop
09:41 rue_house hmm
09:41 rue_house .3w loss for ever .6w
09:41 rue_house 12V 1A
09:42 rue_house 6s 3p
09:42 rue_house 18 leds
09:45 katsmeow-afk see the scope torn apart in the middle : http://designerthinking.com/images/IMG_3192.jpg
09:45 katsmeow-afk it's now lower right and running : http://designerthinking.com/images/IMG_3193.jpg
09:46 katsmeow-afk open 250u 150v cap, not working 50k pot, blown fuse
09:49 katsmeow-afk i replaced the cap with a 330u 250v, clipped out and jumpered the pot with resistors, replaced the fuse with one i have and ordered the correct one
09:51 rue_house :)
09:51 katsmeow-afk this is one of those in the stack on the right, see all the button damage , my cost for it, delivered, but bashed in and not working: 99 cents : http://designerthinking.com/images/DSCF6538.jpg
09:52 rue_house bbl!
09:52 katsmeow-afk i still haveto replace the buttons and knobs, not going to till i have a known dead crt, ergo not fixable, i can pull parts from
09:52 katsmeow-afk have funs
09:54 katsmeow-afk basically, the ebay page for it showed a pretty pic of the scope, all unbashed, and i won the auction for it at 99 cents because no one else bid, and when i complained that they used one 1/8 thickness of bubble wrap and had refused another $50 to pack it correctly, they refuned the s&h
09:55 katsmeow-afk an hr to make the electronics good, and it may take a day to rebuild the busted switches when i can get some off a donor unit
13:17 katsmeow-afk all the airmass over Alaforkingbama is blowing east-to-west, and the stench of smoking garbage piles is nauseating
13:32 Tom_itx is the stench from north-to-south any better?
13:38 katsmeow-afk much
13:38 katsmeow-afk and often the west-to-east is only in evenings
13:39 katsmeow-afk this time of year, the stench of winds south-to-north is mostly wood and leaves burning
18:32 katsmeow-afk Welcome to the MED computer Museam!
18:32 katsmeow-afk IBM PS/2 With Micro Charnel Architecture
18:33 katsmeow-afk This is an IBM personal typing system II. As its name implies it was designed as a word processing mashing
18:34 katsmeow-afk a haze compatible modem,
18:34 katsmeow-afk The printer and computer both have there original boxes.
18:49 Tom_itx kat
18:49 katsmeow-afk Tom
18:50 Tom_itx wanna help wire something?
18:50 tsmeow-afk lis
18:50 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/new_pause_resume.jpg
18:50 Tom_itx that works
18:51 Tom_itx however it false triggers when the device is first turned on
18:51 Tom_itx i want to try a D flipflip and use reset to hold it until it's ready to use
18:51 Tom_itx replace "EDGE" with the flip flop or add it to the end of it
18:51 Tom_itx what i need out is a pulse
18:52 katsmeow-afk can you use any 74LS chip?
18:52 Tom_itx this is software
18:52 katsmeow-afk can you simulate any 74LS chip?
18:52 Tom_itx but uses logic symbols to describe it
18:52 Tom_itx hold on
18:53 Tom_itx http://www.linuxcnc.org/docs/html/
18:53 Tom_itx scroll near the bottom and you can see the available functions
18:53 Tom_itx flipflop is one
18:53 Tom_itx i'm using edge
18:53 Tom_itx oneshot is very similar to edge
18:53 Tom_itx none of those have an inhibit line
18:54 Tom_itx i could put some logic on the output
18:54 katsmeow-afk look at the 74LS221 and the LS123 , both have /CLR (aka /RESET), both are one-shots, can you simulate them?
18:54 Tom_itx maybe another and gaet
18:54 Tom_itx no
18:54 Tom_itx oneshot doesn't have that
18:55 Tom_itx i could use basic logic gates
18:55 Tom_itx and or not xor etc
18:55 katsmeow-afk you have 4066 ?
18:55 Tom_itx i have an estop that is on until it's ready
18:55 Tom_itx i could use as a signal
18:55 Tom_itx what's a 4066?
18:55 katsmeow-afk quad fet switch
18:56 Tom_itx maybe an xor on the output of the pulse
18:56 katsmeow-afk or another AND gate?
18:56 Tom_itx yeah
18:56 Tom_itx i can use the estop signal
18:56 Tom_itx as a 'wait' until ready
18:57 katsmeow-afk ok, AND gate the 1/0 pin , make one pin be low always until power is above 4.7v , and always low below 4.7v vcc
18:57 Tom_itx it works, it's just annoying to have it fault on startup
18:57 katsmeow-afk use a analog comparator to sense the 4.7v
18:58 Tom_itx it needs to be one of those software components
18:58 katsmeow-afk or, change the two AND you have to 3-input AND, and drive the added input with the comparator (4.7v sense)
18:58 Tom_itx it may be triggering the edge on start, not the and gates
18:59 Tom_itx i have no way to find out either
18:59 katsmeow-afk you seem to be really very limited on what software components you have
18:59 Tom_itx it's doable
18:59 katsmeow-afk ok, test: disconnect the NAD fedding the EDGE, and see if it still faults on startup
18:59 Tom_itx good idea
19:00 Tom_itx still faults
19:01 katsmeow-afk is the I/O at least as long as the pulse?
19:01 katsmeow-afk does the I/O start up low?
19:01 Tom_itx if i disconnect the edge output it doesn't fault
19:01 katsmeow-afk if yes-yes, then add an AND to each EDGE output and wire the I/O to them
19:01 Tom_itx that's what i was thinking
19:02 Tom_itx tie the 'AND' to the edge output and to the NON estop signal
19:02 Tom_itx i gotta find that signal now
19:02 katsmeow-afk i am trying to not bring the ESTOP into this yet
19:03 Tom_itx well that's the condition that needs tripped before it can work right
19:03 Tom_itx so estop is the key
19:03 Tom_itx or the signal present when estop is off
19:03 katsmeow-afk i see no ESTOP on the new_pause_resume.jpg
19:03 Tom_itx no, you would't. i'm just telling you that i have it
19:03 katsmeow-afk blahblahblah ... add an AND to each EDGE output and wire the I/O to them
19:04 Tom_itx i will add it and try
19:04 Tom_itx yes i agree with adding the and gates
19:04 Tom_itx the other half of the AND will tie to the 'READY TO RUN" signal
19:04 Tom_itx once i find the name of it...
19:04 katsmeow-afk huh?
19:05 Tom_itx i have a whole bunch of signals in the program i can use
19:05 katsmeow-afk on new_pause_resume.jpg , i see : I/O pin, halui.program.resume , halui.program.pause
19:05 Tom_itx i will find one that becomes active when ESTOP is off
19:06 Tom_itx this will be in addition to what you see
19:06 katsmeow-afk if you AND gate the .resume and .pause with the I/O , it shouldn't fart on startup
19:06 katsmeow-afk because you answered "yesy" to both questions regarding those signals
19:06 Tom_itx huh?
19:06 Tom_itx lemme try something here...
19:06 katsmeow-afk [18:45] <katsmeow-afk> is the I/O at least as long as the pulse?
19:06 katsmeow-afk [18:45] <katsmeow-afk> does the I/O start up low?
19:07 katsmeow-afk [18:46] <katsmeow-afk> if yes-yes, then add an AND to each EDGE output and wire the I/O to them
19:08 katsmeow-afk the signals are already there, and you can throw AND gates at it in software like they are free
19:10 Tom_itx i don't follow what you mean by the pulse width
19:10 katsmeow-afk the EDGE output is a pulse, yeas?
19:10 Tom_itx and i can't tell if it starts low or not
19:11 Tom_itx edge is a puls
19:11 Tom_itx e
19:11 Tom_itx and i can program it's width
19:12 katsmeow-afk ok,, i guess i should ask if you will want me to suggest circuits which you make happen, when you ask me [18:34] <Tom_itx> wanna help wire something?
19:13 Tom_itx the AND gate will fix it
19:13 Tom_itx you did help
19:14 Tom_itx i'm digging for a signal right now though
19:14 katsmeow-afk you aren't going to use I/O , even as a trial?
19:15 Tom_itx i didn't get that part... sry
19:15 katsmeow-afk while i am reasonably sure ESTOP will do just as you say, i have seen humans bypass esopts on machines, have someone else hold them as the machine started, etc
19:16 Tom_itx it's not a critical signal
19:16 Tom_itx it won't matter who triggers estop
19:16 katsmeow-afk in one case, the machine operator had 2 people hold the Estop buttons while he put his hands in where the machine cut them off
19:16 Tom_itx it will clear the startup error which is what i'm after
19:16 Tom_itx well he had that coming then
19:17 katsmeow-afk but if someone holds the estop at startup, the glitch will get thru, is what i am saying
19:17 Tom_itx it starts up with estop enabled by default
19:17 Tom_itx it's a software button
19:17 Tom_itx not hardware
19:17 Tom_itx no control over that
19:17 Tom_itx i do have an external estop button but i'm after the signal not the button
19:18 katsmeow-afk can't manually cause the estop ?
19:18 Tom_itx sure
19:19 Tom_itx see the other signals that feed the 2 AND inputs aren't active until it's first brought out of ESTOP
19:19 tsmeow-afk is so not understannding something, but is trying to fix the glitch as local to new_pause_resume.jpg as possi
19:19 Tom_itx once that happens it doesn't fault again
19:19 Tom_itx it's all a software issue
19:19 Tom_itx i presented it as a logic gate thing
19:19 Tom_itx so you would understand it quicker
19:20 Tom_itx rather than showing you the code and not understanding it at all
19:20 Tom_itx i will have it fixed this evening
19:20 katsmeow-afk thanks, but you have not found the ESTOP signal yet
19:20 Tom_itx using the AND gates one the output of the EDGE
19:20 Tom_itx true
19:20 Tom_itx but i'm confident
19:20 katsmeow-afk so try the I/O signal that's right there
19:21 tsmeow-afk stops suggesting that
19:22 Tom_itx i don't understand what you're asking
19:22 katsmeow-afk [18:51] <katsmeow-afk> [18:46] <katsmeow-afk> if yes-yes, then add an AND to each EDGE output and wire the I/O to them
19:23 katsmeow-afk i dunno how else to say it simply
19:23 katsmeow-afk going afk to put hind paws up
19:24 katsmeow-afk my legs are shakey from carrying scopes :-/
19:30 Tom_itx http://www.linuxcnc.org/docs/html/man/man9/estop_latch.9.html
19:30 Tom_itx i can probably use that
19:30 Tom_itx but i'm not sure that's the one i want
19:44 Tom_itx ok i found the signal.
19:44 Tom_itx machine.is-on
19:55 rue_house mmm nice rack scopes
20:12 rue_house Lola8088, poke opoke
20:16 Tom_itx katsmeow-afk
20:16 Tom_itx it works
20:17 Tom_itx i added 2 AND gates to the output of EDGE
20:50 rue_house its still cryptic to me
20:51 rue_house the source names dont mean anything to me
20:51 Tom_itx i know
20:51 Tom_itx they are software signals from linuxcnc
20:52 rue_house I know
20:52 Tom_itx did you look at the code too?
20:52 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/pause_resume.txt
20:52 Tom_itx the bottom part is that diagram
20:52 rue_house iir its a mess too
20:53 rue_house the signal names dont have context to me
20:53 Tom_itx it's for a pause resume button control on the pendant
20:53 rue_house I should set up a machine to operate my new cnc
20:53 Tom_itx it's a better version of the code above it
20:54 Tom_itx you should set up linuxcnc
20:54 rue_house wonder if it'll run from a 500Mhz itx ok
20:54 Tom_itx of course
20:54 rue_house I have a pile of them
20:54 Tom_itx it's not the speed, it's the latency
20:54 Tom_itx most guys run old MBs
20:54 Tom_itx they're better
20:54 Tom_itx things like bad graphics etc screw up the latency
20:55 rue_house I'm > < thining about rewriting the old cnc software to operate step/direction io
20:55 Tom_itx your time would be better spent setting up linuxcnc
20:55 rue_house the idea is that then the hardware could be used with linuxcnc
20:55 Tom_itx you can still use the parport for io, step directon etc
20:56 rue_house right now the motors take up 12 bits of 2 parallel ports
20:56 Tom_itx or add good hardware at any time
20:56 rue_house cause its per phase control
20:56 Tom_itx i'd love to talk you into some mesa boards
20:57 Tom_itx they are real nice
20:57 rue_house rather simpel generic
20:57 Tom_itx he actually sent me 2 boards free
20:57 Tom_itx those IO boards
20:57 rue_house yea, I have mega32 based ones :)
20:57 Tom_itx the fpga make it run real fast
20:58 rue_house it shouldnt' have to
20:58 Tom_itx all the stepping is done on board
20:58 rue_house steppers aren't fast
20:58 Tom_itx you get much better stepper performance
20:58 Tom_itx i know but you get alot better performance than parport
20:58 rue_house pfff
20:59 Tom_itx mine is doing 40000 steps per inch
20:59 rue_house it takes 3ms or more for the motors I ahve to make the step, if hardware cant keep up with that, there is tooo much bloat
21:00 Tom_itx you could switch to servo
21:02 rue_house my cnc does 14400/19200 and 16000 steps per inch
21:02 rue_house t1 = ((double)width/(double)14400)*x_scale;
21:02 rue_house t2 = ((double)height/(double)19200)*y_scale;
21:02 rue_house t3 = ((double)255/(double)16000)*z_scale;
21:03 Tom_itx the gecko drivers default is 10 microstep
21:03 Tom_itx but it filters it internally
21:03 rue_house my machine has atleast 8 thou play in any direction
21:04 Tom_itx my x is pretty sloppy too but you can enter comp numbers and it will add that in the cuts
21:04 Tom_itx my x probably has more than that
21:04 rue_house I cant make acme thread ont he lathe....
21:04 rue_house er
21:04 rue_house can
21:04 Tom_itx you run a dial indicator on it and then enter the numbers in the software
21:05 rue_house I been thinking of making a small mil
21:05 Tom_itx not smooth accurate ones can you?
21:05 rue_house l
21:05 rue_house dunno
21:05 Tom_itx you'd be ahead to get it
21:05 Tom_itx and build the rest
21:05 rue_house I have a cutter for acme thread I'm kinda into trying out
21:05 rue_house it would help if the lathes low speed was lower
21:06 Tom_itx my lathe is too shot to try cutting threads i'm afraid
21:06 rue_house 20rpm or so would be nice
21:06 Tom_itx my bud has gears for cutting 3 tpi
21:06 Tom_itx most don't go that low
21:06 rue_house indeed
21:07 Tom_itx he's got an older but real nice lathe
21:07 Tom_itx much bigger than a hobby lathe
21:07 Tom_itx foot brake etc
21:08 rue_house the reason that my setup prolly works so well for me is that I'm using dos, non-multitasking means realtime software, which works great
21:08 Tom_itx got that usb connector fixed
21:08 rue_house running steppers off linux has sucked,
21:08 Tom_itx printer is back in business
21:08 Tom_itx not mine but still fixed
21:08 rue_house as soon as the multitasker changes gears the step speed goes to hell
21:09 Tom_itx guys have written gear change routines into linuxcnc just for that
21:09 rue_house no, I'm talking about the kernels process scheduler
21:10 rue_house when it changes what its doing the timing of all the programs drastically changes
21:10 Tom_itx well that's why they run rtai
21:10 rue_house and you still ahve to have an fpga to keep up with stepping motors on time :/
21:10 rue_house just sayin
21:11 rue_house my 386 w/dos does a great job
21:11 rue_house :/ this software goes back to 1997
21:12 Tom_itx i got 48 io on one board and 32 on the other beside what i have on the main 2 boards
21:12 Tom_itx ooo that's gotta be good software!
21:13 rue_house at tech school I was gonna write a g-code interperter for it
21:13 rue_house never did it
21:21 Tom_itx id rather put the puzzle together instead of making each piece of it first
21:21 Tom_itx there are only so many days in the average human life
22:18 rue_shop3 what good is a colour code if you cant tell a 2% 2.10M from a 2% 2.40k?
22:19 Tom_itx a good meter will solve that
22:19 Tom_itx even a not so good one
22:24 rue_shop3 well I sorted about 200 1% resistors, now I have a better grasp of reading them
22:24 rue_shop3 there are a few 2% that seem to use a totally different code
22:25 rue_shop3 I sort by 5 band multiplier colour
22:25 rue_shop3 er 4 band
22:26 rue_shop3 silver/gold/black, brown, red, and orange drawrs are full....
22:26 rue_shop3 cant put away what I just sorted
23:24 Lola8088 /msg rue_shop3 dong
23:34 katsmeow-afk i fell asleep, a function i am still unsure of how to do properly... i totally failed at it last nite
