12:34 AM orlock: Sure, i'll give it a try
07:15 AM tsglove2 is now known as tsglove
09:02 AM z64555: dangit, I want to build a skid steer
05:03 PM _unreal_: helllo
05:03 PM _unreal_: rue_, did you really have an mp4301 on hand?
05:05 PM _unreal_: #@$%@#$%@#!$ 10th phone call since I got home 38 min ago
05:05 PM _unreal_: fuck it I'm turning my phone off
05:08 PM _unreal_: and Soooo annoying That I was disconnected when ever I was hopping to read the rest of the log between rue_ and mrdata
05:09 PM _unreal_: rue_, saddly I only have 3 mp4301's and there already soldered onto a perf board
05:09 PM _unreal_: I'd like to put them onto a breadboard to help match.....
05:23 PM _unreal_: rue_, are you using an LM339 OR AN lm393?
05:56 PM _unreal_: arg
07:08 PM rue_: there you are
07:08 PM rue_: yes I did
07:08 PM rue_: _unreal_, over about 0.5A, it starts to overheat
07:08 PM rue_: it is a horrid chip
07:09 PM _unreal_: heh
07:10 PM rue_: _unreal_, I couldn't get close to 1A without the chip feeling dangerous, when I looked at the datasheet, its got like a 1.5-2V drop on it
07:10 PM _unreal_: nothing like a GOOD CLEAN horid chip
07:10 PM rue_: which is just insane
07:10 PM rue_: so I took the design and ported it to use some irfz44 mosfets
07:10 PM rue_: seeing as that chip is just 4 transsitors and 4 diodes anyhow
07:10 PM _unreal_: I have a number of quad pack darlingtons
07:11 PM rue_: they wont do much better
07:11 PM _unreal_: pu4146's for examply
07:11 PM _unreal_: example
07:11 PM rue_: look at the Vce(sat) spec, if its even 1V, thats bad
07:11 PM rue_: I suppose you dont want to use irfz44 fets eh?
07:12 PM rue_: that pack, at the rated 4.4w must hit over 100c
07:13 PM rue_: and I was using it in swtiching mode
07:13 PM _unreal_: hum
07:13 PM _unreal_: I dont really care What I use. I was just thinking hay I have a thing
07:14 PM _unreal_: already setup
07:14 PM _unreal_: hoping to not use dropping resistors
07:14 PM rue_: we can, but I dont know if it'll push enough current for you to use
07:14 PM rue_: dropping resistors or pwm, wont matter, that chip gets HOT
07:15 PM rue_: the circuit I have going is kinda complex, I'm trying to reduce it down a bit
07:15 PM rue_: you said you have a 44xx chip, what was the number?
07:15 PM rue_: or was it another 41xx
07:16 PM _unreal_: There was a thing on line pminmo
07:16 PM _unreal_: had this linear current control setup
07:16 PM _unreal_: let me see if I can find it. its an archive.org resource at this point
07:16 PM _unreal_: I can always purchase it
07:16 PM _unreal_: $ money isnt an issue but simple IS
07:17 PM rue_: the irfz44 thing works good
07:17 PM rue_: no heatsinks req'd
07:18 PM _unreal_: https://web.archive.org/web/*/http://pminmo.com/
07:19 PM _unreal_: trying to find the right link
07:21 PM _unreal_: trying to find the circuit
07:22 PM rue_: I have the circuits in the datasheets?
07:22 PM _unreal_: foud it
07:22 PM _unreal_: found it
07:22 PM _unreal_: https://web.archive.org/web/20140914214330/http://www.pminmo.com:80/3axisPIC/3axisPIC.htm
07:22 PM _unreal_: Current limiter to go with the 3 axis PIC
07:22 PM _unreal_: Ultra Simple!
07:23 PM rue_: 6 wire motor
07:23 PM _unreal_: current limiter circuit
07:24 PM _unreal_: wire count doesnt matter look at the design
07:24 PM rue_: hahah big burn mark aroudn the left resistors
07:24 PM _unreal_: shhhhhhh
07:24 PM rue_: ah good point, but hmm
07:24 PM rue_: a pwm limiter like that is alsmost as easy
07:25 PM _unreal_: I thought you might like it
07:25 PM _unreal_: god and they say shit on the internet is for ever BS
07:25 PM rue_: mmrmm
07:25 PM _unreal_: huh?
07:25 PM _unreal_: nore sure what mmrmm means
07:25 PM _unreal_: not'
07:25 PM rue_: means I want to go another way
07:26 PM _unreal_: just dont go twards the light
07:26 PM rue_: 5 wire motor drained me back to what I'm working on tho
07:26 PM _unreal_: tonight I can "stay up late"
07:26 PM _unreal_: seeing as how I'm a few hours ahead of ya
07:26 PM _unreal_: I do need to feed my daughter soon though, cumming up on 8:30pm
07:27 PM _unreal_: My home machine I'd RATHER build the controller because I've built everything else
07:27 PM _unreal_: from scratch totally
07:27 PM _unreal_: the machine I'm working on building for work. I"ll spend $ on
07:27 PM rue_: I have the pwm limiter working, but I need to pair down the driver arrangement a bunch
07:28 PM _unreal_: looking at these for my big CNC but I have not decided exactly what I want to drive the big machine with? https://www.aliexpress.com/item/5PCS-CNC-Single-Axis-4A-TB6600-Stepper-Motor-Drivers-Controller/32850829689.html?spm=2114.search0104.3.1.4852704boE2V3d&ws_ab_test=searchweb0_0,searchweb201602_3_10152_10151_10065_10344_10068_10130_10324_10342_10547_10325_10343_10546_10340_10548_10341_315_10545_10696_531_10084_5723616_1008

07:29 PM _unreal_: stepper bip/uni or DC servo etc....
07:29 PM _unreal_: my home machine is unipolare period
07:29 PM rue_: https://www.aliexpress.com/item/5PCS-CNC-Single-Axis-4A-TB6600-Stepper-Motor-Drivers-Controller/32850829689.html
07:29 PM _unreal_: you make that link look so simple
07:29 PM rue_: no, 6 wire unipolar
07:30 PM rue_: just stop at the ?
07:30 PM _unreal_: For what ever reason any link you post comes up in russian if its a web site
07:30 PM _unreal_: freaking wierd
07:31 PM rue_: everything after the ? is your address, credit card information, drivers liscence, and cell phone password
07:31 PM rue_: without it they think your in russia
07:31 PM _unreal_: hum
07:31 PM _unreal_: at least they didnt get my blood type
07:32 PM _unreal_: shhhh O-
07:32 PM rue_: ok, for either of my designs, you need two 2w, 0.33 ohm resistors
07:32 PM _unreal_: if I go "silent" its because I'm working on dinner
07:32 PM rue_: yea
07:33 PM _unreal_: I'd have to purchase those
07:33 PM rue_: how about steel bailing wire?
07:33 PM _unreal_: hum
07:33 PM _unreal_: funny thing I might have that
07:33 PM rue_: I dont know where you are (russia, obviously) can you get parts in a reasonable amount of time?
07:34 PM _unreal_: south florida
07:34 PM _unreal_: I'm just north of miami
07:34 PM _unreal_: .......... on the large scale I'm just north of miami
07:34 PM rue_: 0.33 ohms might be about 6" of bailing wire, run 1A thru it (with a light bulb) and measure the votlage drop
07:34 PM _unreal_: I'm in Boca raton
07:35 PM _unreal_: i'd just order parts
07:35 PM rue_: at 1A you want 0.33V
07:35 PM _unreal_: mouser. digikey etc....
07:35 PM rue_: hmm, so I have to get all the parts right the first time
07:35 PM _unreal_: :)
07:36 PM _unreal_: I'm not saying I'm rich but money isnt an issue for me
07:36 PM * rue_ doodles on the schematic he's doin
07:36 PM rue_: hows your perfboard supply
07:36 PM _unreal_: I mean HELL i have annual passes to disney world and universal world for both my daughter and I
07:36 PM rue_: I want to do a microstepping version of this unipolar driver
07:37 PM _unreal_: I spent about $2k on radioshacks going out of business sails
07:37 PM _unreal_: sales
07:37 PM rue_: do you ahve any 74ls595?
07:37 PM rue_: haha
07:37 PM rue_: and you dont have any 0.33 ohm resistors?
07:37 PM _unreal_: I'd have to look in my electronics dump bins so off the top of my head likely
07:37 PM _unreal_: high power resistors no
07:38 PM rue_: well have your daughter help sort all the pretty things
07:38 PM _unreal_: 2w 0.33 not likely
07:38 PM rue_: 2N7000 ?
07:38 PM rue_: PN2222?
07:38 PM rue_: lm393?
07:38 PM _unreal_: I was like 2n7000 AHHHHHH?
07:38 PM rue_: 1N914
07:38 PM Tom_L: oooo i got some of those!!!
07:39 PM _unreal_: I'm sure I have a shit load of the npn/pnp 2n222's
07:39 PM _unreal_: transistors
07:39 PM _unreal_: lm393 I'm not sure if I have those in NEW or desolderd supply
07:39 PM rue_: http://ruemohr.org/~ircjunk/shop/semiparts1.jpg
07:39 PM _unreal_: I may have non I'm not sure
07:39 PM _unreal_: fuck you
07:39 PM rue_: hahahah
07:40 PM rue_: like I said, I can easily design something you cant make
07:40 PM Tom_L: that goes for cad too
07:40 PM rue_: http://ruemohr.org/~ircjunk/shop/semiparts3.jpg
07:40 PM _unreal_: I prob have enough random electronic components to fill the top 2 rows of that photo
07:41 PM rue_: so yea, I had a few 4301 around
07:41 PM rue_: the intent is to be able to make ANYTHING I can think of without having to get more parts
07:41 PM _unreal_: I'm ok at cad, cgi cad
07:42 PM rue_: http://ruemohr.org/~ircjunk/shop/semiparts4.jpg some newer stuff from china too
07:42 PM _unreal_: I think I spent like 3k on www.hobbyking.com on quadcopert shit
07:43 PM rue_: cool
07:43 PM rue_: can you get an computer power supply for parts?
07:43 PM rue_: (lm393, diode packs)
07:44 PM _unreal_: wtf I have 16GB ram in this laptop running linux and I'm caching
07:44 PM rue_: are you running one of the scripts trying to hack me in the background?
07:44 PM rue_: must be 64 bit limux
07:45 PM rue_: 32bit is waaay more memory efficient
07:45 PM _unreal_: I may have some diode packs I believe 8x diode diode pack
07:45 PM _unreal_: I have chrome and fox open with like 30 tabs each
07:45 PM rue_: we want power shottkey dual diode packs, common cathode
07:45 PM _unreal_: I may have that I'd have to look
07:45 PM rue_: oh, I should close chrome
07:46 PM _unreal_: almost night need to make din for kid
07:46 PM _unreal_: she is only 9
07:48 PM rue_: at 10 build a robot
07:48 PM orlock: _unreal_: Swapping you mean?
07:51 PM orlock: _unreal_: You can tweak the swappiness, if you really want to - That's going to be data that the kernels decided wont be used
07:57 PM rue_: total used free shared buffers cached
07:57 PM rue_: Mem: 8308028 2945784 5362244 0 249304 862104
07:57 PM rue_: -/+ buffers/cache: 1834376 6473652
07:57 PM rue_: Swap: 20980852 0 20980852
07:58 PM rue_: 48 tabs open
07:59 PM rue_: 4 datasheets in adobe
07:59 PM rue_: eagle
07:59 PM rue_: 11 terminals
07:59 PM rue_: wtf, rlly, only 11?
07:59 PM rue_: huh
08:01 PM rue_: ok, the design as it seems to be
08:01 PM rue_: 2 2-pack shottkey common-cathode diodes
08:01 PM rue_: 4 irfz44
08:02 PM rue_: 2 0.33R 2W resistors
08:02 PM rue_: 4 10R resistors (1/4w)

08:02 PM rue_: 4 1k resistors (there will be more)
08:02 PM rue_: 4 1n914 diodes
08:03 PM rue_: 6 2N7000 mosfets
08:03 PM rue_: an LM393
08:04 PM rue_: 2 1k resistors (told ya, but its not over yet)
08:04 PM rue_: 2 0.02uF ceramic caps
08:04 PM rue_: 2 330R resistors
08:05 PM rue_: missing 2 caps, cant remember the value....
08:05 PM rue_: 2 0.047uF ceramic caps
08:05 PM rue_: a 1k pot (current set)
08:05 PM zhanx: rue_, you are babbling
08:05 PM rue_: 1 3.9k resistor
08:05 PM rue_: parts list for _unreal_
08:06 PM orlock: had a look in the bin on my way home last night
08:06 PM orlock: found 6x strips of RGB LED lights
08:06 PM orlock: unsure if they are WS8211 or dumb led strips
08:07 PM rue_: hwo amny wire?
08:07 PM orlock: 4
08:07 PM rue_: dumb
08:07 PM rue_: else 3
08:07 PM rue_: nice score tho
08:08 PM zhanx: rue_, normally i do the drinking you do the thinking , did you change it up?
08:08 PM rue_: those are the parts for a unipolar, pwm current controlled 4 phase, 5 wire motor driver
08:08 PM rue_: it not as bad as I thought it'd be
08:09 PM rue_: 5*7 pcb?
08:09 PM rue_: switches at 30Khz
08:10 PM rue_: and with some '595 and a few resistors, I can get microstepping from it
08:11 PM rue_: buuut, they have modes to controll things during accel and decel, I'm not sure how to do all that
08:11 PM rue_: the usernames in the ssh attacks suddenly changed
08:11 PM rue_: their all specific stuff now
08:12 PM zhanx: its pulled from the sharia blue bot new
08:12 PM zhanx: net*
08:12 PM rue_: victor and test6
08:12 PM rue_: blue bot?
08:12 PM zhanx: sharia blue hired a firm to make a huge bot net to spam by fee
08:13 PM zhanx: or for a smaller fee use the api
08:13 PM rue_: I'm gonna set up a trap machine, see if I can reverse take over part of the net
08:13 PM zhanx: like 45% i bet
08:13 PM orlock: zhanx: Docs?
08:13 PM rue_: their almost all web servers
08:13 PM orlock: WP? Drupal? IIS?
08:14 PM rue_: most of them running gngix
08:14 PM orlock: or quite likely embedded linux hosts?
08:14 PM zhanx: orlock, just redid this machine for the os
08:14 PM zhanx: i had them before, it was outdated severs and stuff like that
08:14 PM rue_: they looked like older linux kernels
08:14 PM rue_: which is funny, cause I'm not running a new one myself, but yea
08:15 PM zhanx: yea i know they had an expliot for Point of sales
08:16 PM rue_: did you get a copy of what they run?
08:16 PM zhanx: no, i tried it was beyond me
08:16 PM rue_: iirc, from the hit that I got, its a loopback fs with a software set on it
08:16 PM zhanx: hence i had a printer for 3 days that was exploited
08:16 PM rue_: under a hidden dir
08:17 PM zhanx: could not figure out how
08:17 PM rue_: huh
08:17 PM rue_: annoying whent eh hackers know more than us eh?
08:17 PM zhanx: your store coupon printer is a linux box
08:17 PM zhanx: yes it is
08:17 PM rue_: I want to see the passwords their trying with these logins
08:17 PM zhanx: not to violate my nda, simple
08:18 PM zhanx: most of the time mac address like even
08:18 PM rue_: hahah, "the linux on this printer has been hacked, not that I'm saying I know anything about how your printer works..."
08:19 PM zhanx: its a busybox server with 1 gig of ram that adds up
08:19 PM orlock: i see weird shit
08:19 PM rue_: insane
08:19 PM orlock: i could set up a nuts honeyput
08:19 PM zhanx: 10,000 of those is a huge cluster
08:19 PM orlock: but it's not justifiable or in my job description
08:20 PM rue_: I have a machine I set up before but didn't put online
08:20 PM zhanx: tomorrow i am fixing the printer i fixed 5 times already
08:20 PM rue_: passwd is a custom program thats results go to a line printer on the parallel port
08:20 PM rue_: and the outbound connection count is like 5
08:20 PM zhanx: seems they can't help but run stapled forms through it
08:20 PM rue_: (limited)
08:20 PM rue_: haha
08:21 PM zhanx: these are network printers
08:21 PM zhanx: well a printer with a busybox attached to it
08:21 PM orlock: how are they getting exploitet?
08:21 PM rue_: I'm gonna do some stuff, then put this circuit togethro for _unreal_
08:21 PM orlock: are they available to internet?
08:21 PM rue_: admin 1234
08:21 PM zhanx: orlock they are on the internet
08:21 PM rue_: some big corps give everything public ip's
08:21 PM zhanx: and the password may or not be the mac address
08:22 PM rue_: I seen a bank and a hospotal like that
08:22 PM zhanx: its too common
08:22 PM orlock: rue_: yeah, they are the ones that usualyl also have real firewalls
08:22 PM rue_: yea, but over the internet youc ant query the mac address
08:22 PM orlock: not just NAT
08:22 PM orlock: but
08:22 PM orlock: also people managing them are crap
08:22 PM zhanx: rue_, wrong
08:22 PM rue_: whaaaat
08:22 PM rue_: you have to be on the lcoal network to arp
08:23 PM rue_: ????
08:23 PM zhanx: who said anything about arp?
08:23 PM rue_: whaaaaaa
08:23 PM orlock: some have a http interface that contains it
08:23 PM rue_: whaaaaaaaaaaaa
08:23 PM orlock: or just have shit exploitable web interfaces
08:23 PM rue_: yea
08:23 PM zhanx: rue_, its stupid easy
08:23 PM orlock: hmm
08:23 PM orlock: reminds me
08:23 PM rue_: microsfot and buffer overruns to togethor like crackers and cheese
08:23 PM zhanx: ok look ssid is this
08:23 PM orlock: i need to email the local cybersecurity boffins
08:24 PM orlock: they ignored my first time
08:24 PM zhanx: mac address is that minus this
08:24 PM rue_: but for example (be my guest) you cant get the mac address of my border machine here
08:25 PM zhanx: the store i was at today, sever room was locked
08:25 PM rue_: bump it with your boot?
08:26 PM rue_: haha I ahve 4 interfaces and I'm not sure which IS my public one...
08:26 PM zhanx: one sec i will let you know
08:27 PM rue_: waait, who ks knocking on my interface
08:27 PM rue_: like I'd oppen us for the fbi
08:27 PM zhanx: not me installing the tools now
08:28 PM rue_: who's mario
08:29 PM orlock: https://i.ytimg.com/vi/mJ4Te3BgItM/maxresdefault.jpg
08:29 PM rue_: damnit am I haveing an ssh passwd fail conversation with one of you?
08:29 PM orlock: rue_: https://i.ytimg.com/vi/mJ4Te3BgItM/maxresdefault.jpg
08:29 PM orlock: :)
08:29 PM Tom_L: https://is1-ssl.mzstatic.com/image/thumb/Purple125/v4/db/9d/a6/db9da66d-14ad-20a4-916b-8934d5531199/AppIcon-1x_U007emarketing-85-220-5.png/246x0w.jpg
08:29 PM rue_: hah
08:29 PM orlock: What's th source showing s?
08:29 PM orlock: ipv6?
08:29 PM rue_: Aug 15 18:31:45 t0002 sshd[17245]: Failed password for invalid user MARIO from 103.16.129.82 port 48520 ssh2
08:29 PM zhanx: arp rue me
08:29 PM zhanx: err
08:30 PM rue_: I just happen to be watching the logs
08:30 PM zhanx: me
08:30 PM zhanx: i will stop
08:30 PM rue_: whatever
08:30 PM rue_: I been watching the hacks
08:30 PM zhanx: check your logs
08:30 PM zhanx: i stopped
08:30 PM rue_: 177.43.59.31 ?
08:31 PM zhanx: that is not me
08:31 PM rue_: I dont care, I been musing as they go by
08:31 PM zhanx: i am 96 etc
08:31 PM rue_: damn that a logn password
08:31 PM orlock: rue_: Check the reverse of the IP...
08:32 PM orlock: and the location..
08:32 PM orlock: I'm not really trying to covery my tracks here :)
08:32 PM rue_: no well
08:33 PM zhanx: wait so that is orlock and you didn't see me?
08:33 PM rue_: Aug 15 18:34:29 t0002 sshd[17251]: Failed none for invalid user <rue_> I been watching the hacks from 103.16.129.82 port 48534
08:33 PM rue_: I onyl see the one IP
08:33 PM orlock: zhanx: yeah i'm just sending stupid shit heh :)
08:33 PM rue_: but point is, you dont ahve my mac address
08:33 PM zhanx: rue i did a port scanner and a ssh attempt
08:33 PM rue_: I didn't know you could have a username that long or with spaces
08:34 PM zhanx: no i didn't arp it
08:34 PM orlock: Not on the same L2 network.. you can't
08:34 PM rue_: yea
08:34 PM rue_: thats what I know
08:34 PM zhanx: rue_, you are thinking inside the box
08:34 PM rue_: beyond the local network, the mac address isn't available via arp
08:35 PM rue_: like you said, if the http server exposes it, your pooched
08:35 PM zhanx: how many companies have free wifi now?
08:35 PM zhanx: so kids wardrive and scan it
08:35 PM rue_: I dont think many hackers are ... really?
08:36 PM rue_: standing in the building
08:36 PM zhanx: i could give you all the walmart default configs
08:36 PM zhanx: fyi they are 99% default
08:36 PM rue_: yea, well, pff
08:37 PM rue_: comcast issued millions of routers with a tunnel exploit
08:37 PM rue_: ok, need some food
08:37 PM orlock: zhanx: Going to PM you about some stuff - i already mentioned it to rue a week or so ago
08:37 PM rue_: if you guys notice any exploits on my firewall give me a shout, and I'll be back later
08:37 PM * orlock has returned... [atl]
08:38 PM zhanx: ok orlock
08:38 PM rue_: orlock, hey, just ssh and http are open aren't they?
08:38 PM rue_: think I closed ping...
08:38 PM orlock: rue_: I'm doing a full 0 - 32767 scan now
08:38 PM zhanx: rue_, abd irc due to being used
08:39 PM zhanx: rue_, forgot about port knocking
08:39 PM _unreal_: hear for a few
08:40 PM _unreal_: any suggestions on MACH3/4 pendents
08:40 PM rue_: _unreal_, no
08:41 PM _unreal_: looking at this one WHB04B
08:41 PM rue_: _unreal_, ^^^ parts list, initial
08:42 PM rue_: way up
08:43 PM _unreal_: LOL @ WTF only 11
08:47 PM Tom_L: rue_shop3, i wonder if i can align linear rails so i could but them end to end and make em a tad bit longer
08:47 PM Tom_L: the addition wouldn't be used for load but on the upper end for clearance mostly
08:48 PM Tom_L: the bump would probably wear the bearings out
08:50 PM _unreal_: Tom_L, if you dont have dimpled rails I wouldnt but them unless you can get perfect alignment
08:50 PM Tom_L: i could order just the rails and use the current slides
08:51 PM _unreal_: as long as your bolting to a flat surface and CLAMP the rails when butted to force them perfect, a true alignment may work but if the ends are rounded/debured it may cause an issue
08:51 PM Tom_L: yeah i better not try that
08:52 PM Tom_L: if i had a way to pin them end to end with reliable alignment i might try it
08:52 PM Tom_L: i don't think i have any way to drill an accurate pin hole
08:52 PM _unreal_: a good alignment will work just fine but if there is load it could cause a "HICKUP" in the movement
08:52 PM Tom_L: it would be at the top end of z where it's not used under load
08:52 PM Tom_L: mostly for clearance during a move
08:53 PM Tom_L: i'll probably just wait and get longer rails
08:53 PM _unreal_: then its your call. if its under Load I wouldnt bother unless you have the male/female ends style rail system. if its jts not going to see load then it should prob work just fine
08:54 PM Tom_itx: https://www.ebay.com/itm/New-Hiwin-HGR20R-Linear-Guideway-Rail-HGR20-Series-up-to-4000mm-Long/182458780338?_trkparms=aid%3D888007%26algo%3DDISC.MBE%26ao%3D1%26asc%3D53209%26meid%3Db5908ef167be42869fc606982d25898e%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D191865468264%26itm%3D182458780338&_trksid=p2047675.c100009.m1982
08:54 PM Tom_L: it's that stuff
08:54 PM _unreal_: Your call
08:55 PM _unreal_: you could clamp 2x4's or something to align it then mount it but again thats your call
08:56 PM _unreal_: if its not seeing load, its not likely an issue with good alignment
08:56 PM Tom_L: the extra length would only be around 4" at most
08:56 PM Tom_L: i don't think it's a good idea
08:56 PM _unreal_: :) I'm just going to repeat my self
08:56 PM Tom_L: you saw the mill right?
08:56 PM _unreal_: mill?
08:56 PM _unreal_: no
08:57 PM _unreal_: I was feeding my daughter
08:57 PM Tom_L: i thought you saw it the other day
08:57 PM _unreal_: may have dont recall
08:58 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Mill_Assembly1.jpg
08:58 PM Tom_L: that's not done but you can see the rails on Z
08:58 PM Tom_L: i wanna extend them up and down a little more
08:59 PM Tom_L: mostly down
08:59 PM _unreal_: So how would you add the extra 4"
08:59 PM _unreal_: just float the rail?
08:59 PM Tom_L: i've got cutoff from the other rails
08:59 PM Tom_L: one was 1k mm and that was too long so i cut it
08:59 PM _unreal_: and you'd need to have a longer ball screw
08:59 PM Tom_L: no
09:00 PM Tom_L: there's plenty of room on it for what i need
09:00 PM Tom_L: the nut is in the center of the Z plate
09:00 PM Tom_L: so the trucks extend past it each way a bit
09:00 PM _unreal_: shand the large pully clears?
09:01 PM _unreal_: shand=and
09:01 PM Tom_L: i'm mostly interested in the bottom
09:01 PM _unreal_: OMG that generator is identical to mine but mine has a different MFG
09:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Z-Riser_blocks.jpg
09:03 PM Tom_L: i added those and i think i have enough z for most things but i could use a little more on the bottom now
09:03 PM Tom_L: i raised it for the vise clearance
09:03 PM _unreal_: hehe square tube Z riser
09:03 PM Tom_L: it's pretty solid
09:04 PM _unreal_: I made a G10 cic
09:04 PM _unreal_: cnc
09:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Vise2.jpg
09:04 PM Tom_L: there's the vise
09:04 PM Tom_L: this is entirely scratch built
09:04 PM _unreal_: You milled the vice?
09:05 PM Tom_L: heh, no i bought that
09:05 PM _unreal_: wtf the dog just walked in licked my foot and walked off
09:05 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Mill1.jpg
09:06 PM Tom_L: i either run the vise or a sacrificial plate like you see there
09:06 PM _unreal_: you need dust collection
09:07 PM Tom_L: naw
09:07 PM _unreal_: hand made pendent or did you buy it?
09:07 PM Tom_L: i made it
09:08 PM _unreal_: I'm thinking about buying one
09:08 PM rue_: i made my pendant too
09:09 PM rue_: two fo them
09:09 PM Tom_itx: https://www.youtube.com/watch?v=jRN00-0enYw&t=2s
09:10 PM Tom_itx: there's one of it's early test runs
09:10 PM rue_: im tired and its making me useless
09:11 PM rue_: _unreal_, you gonna check what you have from that parts list?
09:13 PM rue_: rue?
09:13 PM rue_: yea?
09:14 PM rue_: your on your own again.
09:14 PM rue_: oh.
09:14 PM Tom_L: gonna be useless in front of us all ?
09:14 PM rue_: sneaks up eh?
09:14 PM rue_: well, I'm trying to stay awake
09:14 PM rue_: trying to work out what for supper
09:14 PM rue_: what-for
09:14 PM Tom_L: i snapped the tip off my indicator so i gotta wait to tram the axis again
09:15 PM Tom_L: stupid mistake
09:15 PM rue_: 8-|
09:15 PM Tom_L: i got a tip coming
09:15 PM rue_: jogged the wrong way?
09:15 PM Tom_L: uh huh
09:16 PM rue_: the wheel on my pendant drivers the axies different ways on the different machines
09:16 PM rue_: I have to be careful
09:16 PM Tom_L: you should fix that
09:16 PM rue_: yup
09:16 PM Tom_L: make them all the same
09:16 PM Tom_L: right hand rule
09:16 PM rue_: I have so many things on the should-list that I dont even look at it
09:17 PM rue_: I'm gonna buy a drillpress for the new machine
09:17 PM rue_: $75
09:17 PM rue_: I think I'm crazy
09:17 PM Tom_L: chinaco?
09:17 PM rue_: its an old one
09:17 PM rue_: no
09:17 PM Tom_L: i've had mine for quite a few years
09:17 PM Tom_L: i think you saw it
09:18 PM rue_: https://sunshine.craigslist.ca/tls/d/tru-power-heavy-duty-drill/6666077847.html
09:18 PM rue_: its 4.5" deep, fromw hat I can tell
09:18 PM Tom_L: not bad
09:19 PM rue_: and its a taper
09:19 PM rue_: from what I can tell
09:19 PM rue_: I have to drive 2 hours to get it
09:19 PM rue_: I'm insane :/
09:20 PM orlock: no motor
09:20 PM orlock: "great working condition"
09:20 PM orlock: ....
09:20 PM rue_: yea
09:20 PM rue_: I know
09:20 PM rue_: but look at it, its worth more than the $200 drillpresses you can get at the corner store
09:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Drillpress.jpg
09:21 PM Tom_L: getting my money's worth out of it
09:22 PM rue_: its better than my drillpress, dont think I'll trade tho
09:22 PM Tom_L: my old one was a buffalo antique drillpress
09:22 PM Tom_L: i got it with that steel table
09:23 PM Tom_L: pretty much wore out when i got it
09:25 PM rue_: that table looks like its designed for coolant
09:25 PM Tom_L: the one you linked?
09:25 PM rue_: yea
09:25 PM rue_: rotting table... for making boiler plate?
09:25 PM Tom_L: it's made to rotate
09:25 PM rue_: signatures of being old
09:26 PM _unreal_: I have a bunhc of those missing caps
09:26 PM Tom_L: i think that's just how they made em back then
09:26 PM rue_: buts its only 1981
09:26 PM Tom_L: not the rotate part but the table design
09:26 PM rue_: _unreal_, ok, put it all in a box
09:27 PM rue_: its a good one, actually, betweent eh roate and the swing, you can position whereever you want
09:27 PM Tom_L: does the table tilt?
09:27 PM rue_: it looks like it might
09:28 PM Tom_L: i can't tell
09:28 PM rue_: I need to turn it into a cnc
09:28 PM rue_: so lets not analize it too much
09:29 PM Tom_L: where'd the motor go?
09:29 PM Tom_L: kindof an important feature
09:29 PM rue_: not for me, I have a million of them
09:30 PM rue_: the pulley would be a bonus
09:30 PM rue_: the idea is to use the feed as the z of a cnc
09:31 PM rue_: it looks like it could be a whole cnc if I went for r-theta
09:32 PM rue_: ok build circut for _unreal_
09:32 PM rue_: no idea of what to have for supper
09:32 PM rue_: maybe I can fight the cats for soemthing
09:33 PM rue_: what goes well with half-eaten dead bird?
09:33 PM orlock: chips
09:34 PM _unreal_: with out going nuts looking for stuff I have about half the parts
09:34 PM _unreal_: I'd have to oder the other half
09:35 PM rue_shop4: put 'em in a box, I'll test
09:35 PM rue_shop4: you can get 50 irfz44 from china for aout $3
09:36 PM Tom_L: rue_shop4, therein lies the problem with your limit of workspace
10:11 PM rue_shop4: ok, thats the circuit
10:14 PM rue_shop4: _unreal_, I'll draw it all out, it got kinda small
10:28 PM justan0theruser is now known as justanotheruser
11:49 PM rue_: _unreal_, did you die?
11:50 PM _unreal_: I went to bed just got up to piss. it is 1am just about
11:50 PM rue_: thoguht you said you'd be up late!?
