12:21 AM IchGucksLive: morning from germany
12:24 AM XXCoder: hey from rainy tacoma
12:24 AM IchGucksLive: also rain here
12:24 AM gloops: i think its pretty deceiving to sell a 300mm ballscrew that actually only has 175mm of travel
12:25 AM gloops: i will write to the emperor of china to ask him to include 'actual travel ***mm' on all ballscrew adverts
12:26 AM IchGucksLive: gloops: it is always the ovaerall length
12:27 AM gloops: yes - it can make all the difference Ichs
12:27 AM IchGucksLive: as frame size covers the bearing
12:27 AM IchGucksLive: therfor there are advices in the ad
12:27 AM gloops: the nut itself is also 45mm
12:31 AM gloops: how close to the ends of the ballscrew do you move?
12:31 AM gloops: i wanted to leave at least 20mm spare
12:31 AM XXCoder: so thats 29mm per end or 40mm less
12:31 AM gloops: if youre machined for double bearing one end, single bearing the other - total loss = 75mm
12:31 AM gloops: + 45mm off for the nut
12:32 AM gloops: if i took this 300mm screw right to the end of the thread id get about 185mm travel
12:34 AM gloops: may revert to leadscrew for z
12:35 AM IchGucksLive: i use the set 500mm of Rat for most Z
12:36 AM gloops: ive got a t8 screw ill use that, have got 2 nuts for it
12:48 AM IchGucksLive: morning ailaG
12:50 AM IchGucksLive: ailaG: how is the water Temp in telaviv
01:01 AM Tom_L: morning it is...
01:01 AM Tom_L: 1AM
01:01 AM IchGucksLive: 8am
01:02 AM Tom_L: working on cad a bit
01:02 AM Tom_L: trying to get the XY axis plate hole spacing right
01:10 AM gloops: 7 am, gonna go out for a fire in a bit lol
02:00 AM IchGucksLive: later
02:03 AM Deejay: moin
03:03 AM Wolfmetalfab is now known as Wolf__
03:21 AM gloops: ally casting FAIL 2
03:21 AM gloops: https://postimg.org/image/z6x1wwvdn/
03:22 AM XXCoder: your casting?
03:22 AM gloops: yeah
03:22 AM XXCoder: what happened?
03:22 AM gloops: moisture in the mold i reckon, bubbled in one area
03:23 AM gloops: close, got it to melt easy this time anyway
03:24 AM XXCoder: cool :)
03:25 AM gloops: thing weighs 4kg+ though. the 10mm steel plate the same size weighs little more lol
03:25 AM XXCoder: gonna love density
03:25 AM XXCoder: I have samples of tungsein and titanium
03:25 AM XXCoder: both is exactly same shape (ignoring minor errors within tol)
03:26 AM XXCoder: titanium feels like toy besides tungsein
03:26 AM gloops: yeah, strange how strength to weight ratios work out as well
03:27 AM gloops: carbonfibre is far more stiffer than steel per weight
04:38 AM archivist: and shape makes stuff stiffer than the material
04:39 AM archivist: add webs to plate
05:00 AM jthornton: morning
05:00 AM XXCoder: yo
05:17 AM Deejay: heya
05:28 AM gloops: too far for me but...
05:28 AM gloops: https://www.ebay.co.uk/itm/Aluminium-T-slot-Section-plates-for-CNC-bed-or-CNC-hobby-use/282729930237?
05:29 AM archivist: just down the road!
05:30 AM archivist: past my house :)
05:30 AM gloops: cheap..for now
05:31 AM archivist: not very thick so clamping is going to lift them
05:31 AM XXCoder: unless bolted to steel slab?
05:31 AM gloops: be ok supported
05:32 AM gloops: npt enough for me anyway
05:34 AM archivist: just been out on a freecycle collection for a dell monitor
05:39 AM gloops: not looked on there for ages
05:40 AM archivist: I just get the emails, and occasionally see something
05:41 AM XXCoder: jthornton: I used ear protection plug for first time yeserday lol
05:42 AM jthornton: the boss made you use them?
05:43 AM XXCoder: nah, I used it to do strange fix for my phone SIM disconnect crash
05:43 AM XXCoder: I cut 1/3 from one, opened phone back cover, taped it at correct spot, closed case (bit diffult with it there)
05:43 AM XXCoder: it pushes down on SIM and sdcard cabling connection apparently
05:44 AM XXCoder: it used to crash each few hours, now nothing for over 24 hours
05:46 AM jthornton: contacts might be dirty
05:46 AM XXCoder: how?
05:46 AM XXCoder: utterly impossible, its sealed inside lol
05:46 AM XXCoder: (I mean, sealed even when back cover is removed
05:47 AM XXCoder: anyway it fixes by pushing down on connector
05:48 AM XXCoder: I hope fix will be good for another 2 or 3 years
05:48 AM XXCoder: I dont like buying new phones
05:50 AM XXCoder: current record is 5 years for sidekick 2
05:50 AM XXCoder: though almost equaled by blackberry 8830 (slightly less than 5 years) and epic 4g (4.5 years)
05:51 AM XXCoder: this samsung s4 is getting close to 3 years old now
05:51 AM jthornton: my phone started to fail so I swapped over to my wifes old phone both 4S
05:51 AM jthornton: or S4 even
05:51 AM XXCoder: lucky you not getting SIM socket flaw ones
05:52 AM XXCoder: know whats funny? current record for voice call is 5 seconds for epic 4g
05:53 AM XXCoder: all others has zero seconds time.
06:28 AM jthornton: voice call record?
06:32 AM XXCoder: yeah total of voice minutes on device for me lol
06:32 AM XXCoder: 5 seconds total. across entire device usage life lol
06:37 AM jym: XXCoder: and that probably is when you got it and was checking to make sure it worked =)
06:38 AM jym: XXCoder: "Can you hear me now? Good"
06:38 AM XXCoder: nah acciently dialed while trying phone dial code to access settings
06:38 AM jym: XXCoder: You butt dialer you!
06:39 AM XXCoder: lol impossible
06:39 AM jym: XXCoder: You have no butt?
06:39 AM XXCoder: I never have phone with no lock
06:39 AM XXCoder: cant dial on locked phone
06:39 AM jym: XX "no butt" Coder
06:40 AM XXCoder: sire.. it is you, jym! https://smbc-comics.com/comic/royalty
06:41 AM jym: XXCoder: Of fuck that, not even close!
06:41 AM jym: Oh*
06:41 AM XXCoder: lol
06:41 AM XXCoder: now I go off to sleep. later
06:41 AM jym: Sleep?! It's almost 5am
06:42 AM XXCoder: yeah little bit late. normally sleep at 4 am
06:42 AM * jym hands XXCoder a life, cause it seems he doens't have one ;)
06:59 AM miss0r: Am I the only one with a somewhat a ambivalent relationship with tools that are labeled 'PRO' ? :)
06:59 AM archivist: what have you broken?
06:59 AM jym: miss0r: No, just the only one that bought the hype of "I ares a professional" ;)
07:01 AM jym: or what archivist said (same diff)
07:01 AM miss0r: archivist: I didn't break anything.. Well 'now' anyway. it just seems to me that most tools that need to label them self as pro usualy are quite the oposite. but here I have two thürmer taps that are labeled 'PRO' and they ARE infact good quality
07:01 AM miss0r: Its just another label that means nothing
07:02 AM archivist: pro is added to raise the price, like Apple :)
07:02 AM miss0r: Have you even seen a cordless drill with a 'for professional use' that could stand up to any abuse at all?
07:03 AM archivist: seen expensive ones!
07:03 AM miss0r: Hehe - perhaps they are referring to the user should be professional enough to know not to use it for anything hard :)
07:03 AM jym: English is the most bastardized language in existance, even over brainfuck (which actually is quite elegant in it's own way)
07:04 AM miss0r: What you just wrote made no sense to me :]
07:06 AM miss0r: archivist: This is what I was working on the other night: http://picpaste.com/IMG_20171112_140448-QVqdR6ca.jpg 105 x M20x1,5
07:06 AM miss0r: for cable glands
07:06 AM DaViruz: now surface grind it!
07:07 AM DaViruz: so the cable glands sits nice and flush!
07:07 AM DaViruz: that's a pretty hefty plate for cable glands
07:07 AM archivist: he has chamfered the holes
07:08 AM miss0r: DaViruz: Hehe, nah - I took the cheap'n easy way and ordered O-Rings for all of'em
07:08 AM miss0r: archivist: For retaining the O-rings
07:08 AM miss0r: DaViruz: Yeah. The idea is the enclusure should be rated at IP68, so it needs to be somewhat beefy
07:09 AM SpeedEvil: fun
07:09 AM miss0r: SpeedEvil: Not that exactly - It took alot longer to machine than I enticipated.
07:10 AM SpeedEvil: :)
07:10 AM miss0r: Now I need to make 4 'arms' that cold inductive switches for monitoring some flood gates.
07:11 AM miss0r: cold=hold
07:11 AM miss0r: Time to break out the TIG welder
07:13 AM DaViruz: phttp://proto-design.dk/images/custom_bolt_repair-large.jpg
07:13 AM DaViruz: aah, it's one of those bolts for holes counterbored on the wrong side.
07:14 AM miss0r: I believe that was for a slideway gib
07:15 AM DaViruz: (refering to this one https://i.pinimg.com/474x/b2/a4/28/b2a4288282c88249798ae061e95cf630--nut-bolt-menu.jpg )
07:15 AM miss0r: LOL! That'll be printed right away and get a prime location on the tool locker
07:20 AM SpeedEvil: Now, machine all of them! :)
07:20 AM SpeedEvil: That would actually be a really fun challenge.
07:20 AM DaViruz: i'll order a few of the "for redrilled holes that still don't match"
07:23 AM miss0r: DaViruz: How many would you like to order? :D
07:23 AM miss0r: Its actualy a pretty funny gimmic
07:24 AM miss0r: I should make a set to give to someone who makes alot of stupid mistakes
07:26 AM MarcelineVQ: "Nut is hard starting" hehe
07:28 AM SpeedEvil: miss0r: I am annoyed I can't find the link to offset dowels.
07:28 AM miss0r: hehe, Now that is something that could come in handy once in a while :]
07:28 AM SpeedEvil: miss0r: for wood, there was a seller on amaxon selling injection moulded glassfibre dowels with stepped offsets up to a little over half the diameter
07:28 AM Loetmichel: DaViruz: the tool for "redrilled holes that still dont match" is called "welder"... and then redo it a the right spot!
07:29 AM miss0r: SpeedEvil: wtf
07:29 AM archivist: Loetmichel, or riveting
07:29 AM Loetmichel: miss0r: he is right, have seen those a few times now.
07:29 AM miss0r: That just sounds crazy
07:30 AM Loetmichel: archivist: if you can do rivets: of course. not that many can these days though ;)
07:30 AM archivist: Loetmichel, http://www.collection.archivist.info/searchv13.php?searchstr=pd+norfolk+dial
07:34 AM miss0r: I'm getting frustrated here. Apparently my automation supplyer does not have any M18 A4 IP69K inductive switches with 15mm sensor reach and cable installed in stock! They always have that !
07:35 AM jym: miss0r: Ask them for the "Pro" versions ;)
07:35 AM * miss0r would rather shoote himself
07:35 AM * jym hands miss0r a sack of potatoes... GO AHEAD SHOOT YOURSELF!!!
07:36 AM jym: miss0r: http://spudguns.com/
07:36 AM miss0r: This is what I get for agreeing to spend the weekend with the inlaws! FSCK!
07:37 AM jym: miss0r: SUCKER <snickering>
07:37 AM miss0r: yea... Damnit! They only have M30 in stock. I need to redesign stuff here
07:37 AM jym: miss0r: inlaw time should be measured in minutes (oif not seconds), not hours or DAYS?!
07:38 AM miss0r: tell me about it
07:38 AM jym: miss0r: Jut wear headphones all the time, they'll think your listening to music and not annoy you as much
07:39 AM miss0r: Yeah, one cannot realy do that without comming off as rude. I DID agree to go
07:39 AM jym: miss0r: You agreed to go, not interact.
07:40 AM miss0r: heh. I will remember that the next time. But to be honnest I think it is a bundled package
07:40 AM jym: Yeah, probably.
07:41 AM jym: read the fine print and disclaimers ;)
07:41 AM miss0r: I don't have the correct stock laying around to do that design change... This is gonna be another long night *sigh*
07:42 AM jym: miss0r: breka out the 2nd coffee maker and just alternate between them
07:42 AM miss0r: I think I need to, yeah
07:44 AM jym: miss0r: and crank up the tunes for background noise
07:44 AM miss0r: They will be submerged in sea water. And when 'shit' hits the fan, they will be submerged in sewage at quite a high flow rate. I can't just choose any inductive switch. THAT and they are quite hard to get to when a replacement is needed.
07:44 AM jym: miss0r: mag switch?
07:45 AM miss0r: mag switch ? :S (its a switch that can detect metal infront of it)
07:45 AM SpeedEvil: miss0r: there would seem to be an argument for in-place redundancy. That is - you put in three switches
07:46 AM miss0r: SpeedEvil: Each floodgate is equipped with two. (not up to me)
07:49 AM Loetmichel: jym: i cant complain about my parents in law... other than they are 400km away and i detest the 4 hour drive to get to and fro.
07:49 AM miss0r: Found the damn correct switch "! :D
07:49 AM Loetmichel: they are surprisingly nice people ;)
07:50 AM miss0r: Loetmichel: Don't get me wrong. I like my inlaws. But spending an intiere weekend with them, while I have stuff to do is just a bit... much
07:54 AM Loetmichel: miss0r: i can concur to that. usually its enough for me when wifey drives there saturday morning so i can sleep on the other seat and we drive back at night the same day... thats enough for about 2 months ;)
07:59 AM miss0r: I hear'ya
08:01 AM jym: Loetmichel: 400km away may not be a bad thing ;
08:23 AM jelly-home is now known as jelly
08:24 AM miss0r: DaViruz: I can't remember posting my website in here lately. How did you get the link (Just pondering here)
08:25 AM pfred1: miss0r ve haf vays of finding joo!
08:25 AM miss0r: :]
08:26 AM pfred1: the Internet is not that big
08:26 AM jym: ...fits on a 3.5" FDD
08:26 AM miss0r: That is true
08:26 AM miss0r: What pfred1 said anyway
08:27 AM pfred1: jym I know it just takes forever to decompress it
08:27 AM miss0r: Not much about it. its just different sequences of 1's and 0's
08:32 AM jym: pfred1: That's what 32 core 64 cpu's are for ;)
08:32 AM pfred1: I just got 2 cores
08:32 AM pfred1: I want to upgrade I've been shopping around
08:33 AM * Tom_L has a couple discarded apple cores
08:33 AM pfred1: prices are insane now thuogh
08:33 AM pfred1: in fact everytime I go shopping stuff keeps going up
08:34 AM miss0r: pfred1: I have a server board with two xeon something with 6 cores'n hyper threading, and 64gb memory laying around. Interrested?
08:34 AM DaViruz: miss0r: you engraved the link in the middle of your cable gland plate :)
08:34 AM miss0r: They are only 2.5ghz I believe
08:34 AM DaViruz: i thought it was a shameless plug.
08:34 AM miss0r: DaViruz: Ofcourse! :)
08:34 AM pfred1: miss0r xeon is the one thing that seems cheap these days
08:34 AM miss0r: lol
08:35 AM pfred1: know what I did see cheap?
08:35 AM pfred1: old atom boards
08:35 AM sync: they were always cheap
08:35 AM pfred1: they're lke $28 now
08:35 AM sync: but they also don't have any power at all
08:35 AM miss0r: DaViruz: I like to leave a brand on stuff that is going to be installed where people can see it at some point ;)
08:36 AM pfred1: I thought atoms ran LinuxCNC fine?
08:36 AM Tom_L: they do on rtai
08:36 AM Tom_L: not so much on preempt
08:36 AM pfred1: hmmm hmmm'
08:37 AM miss0r: pfred1: Not kidding about the server board thou. You can have it if you want to pay the shipping fee
08:37 AM pfred1: RTAI is having some problems lately
08:37 AM pfred1: miss0r I appreciate the offer I have my heart set on an i5 right now thugh thanks
08:37 AM miss0r: I used it in my PC for running games not too long ago, that was not a complete success :)
08:37 AM Tom_L: just got an i5 with M2
08:37 AM Tom_L: that's the way to go
08:38 AM miss0r: Alright. I just wanted to put it out there. I have too much equipment that have been laying around for too long for people to want it anymore, and I don't ever seem to get around to use it
08:38 AM pfred1: yeah I have i5itus or something
08:38 AM pfred1: I really want an i5
08:38 AM Tom_L: 7's hardly worth the extra
08:38 AM pfred1: 5s seem like the sweet spot to me
08:38 AM Tom_L: err, maybe my last one was a 7
08:39 AM pfred1: I was thinking about upgrading this system too but I want a whole new PC to do a whole new install on it
08:39 AM pfred1: then i might upgrade this PC
08:40 AM Tom_L: i added a 1Tb M2 960 evo to it
08:40 AM pfred1: yeah I want SSD
08:40 AM Tom_L: that's your biggest gain
08:40 AM pfred1: though with enough RAM HDD speed is not too important
08:41 AM pfred1: once stuff gets cached
08:41 AM Tom_L: once is the part i don't wanna wait for
08:41 AM pfred1: I don't reboot my daily driver much
08:41 AM Loetmichel: Tom_L: i am to cheap to get an 1tb ssd
08:41 AM Tom_L: this one is a clunker but it stays on
08:42 AM Tom_L: Loetmichel, you get used to it...
08:42 AM pfred1: my daily driver is a clunker
08:42 AM Tom_L: i'm just about all ssd now
08:42 AM Loetmichel: su you do, Tom_L. but i refuse to pay so much, so i dont have a single PC with an SSD...
08:42 AM Tom_L: use a 500 for data on most
08:42 AM pfred1: I got it for $1 at a senior center sale
08:42 AM Tom_L: and most have 2 drives in em min
08:43 AM pfred1: I haven't actually bought a PC for real money in a long time
08:43 AM sync: ssds are cheap now
08:43 AM Loetmichel: sync: define cheap
08:43 AM Tom_L: my server was a freebie
08:43 AM pfred1: I used ot just find them here and there
08:43 AM sync: I have a 1T nvme ssd in my machine now, makes such a difference
08:43 AM pfred1: but those days seem over to me now
08:44 AM Loetmichel: i still can get a 2tb spinning HDD for the price of an 128GB ssd
08:44 AM sync: you can, but the performance sucks
08:44 AM Tom_L: rusty ole things...
08:44 AM Tom_L: :)
08:44 AM pfred1: it ain't that bad
08:44 AM sync: it is
08:44 AM pfred1: it isn't
08:44 AM pfred1: what's a few ms?
08:44 AM sync: a lot
08:44 AM pfred1: not to me
08:44 AM Loetmichel: i dont care
08:45 AM sync: it makes a huge difference when randomly accessing small files
08:45 AM pfred1: I guess
08:45 AM Loetmichel: my PCS at home run 24/7 and the ones at the company are started early in the morning and ar operational when i got my first coffee
08:45 AM pfred1: yeah I can see it helping out on compiles
08:45 AM Loetmichel: no problem there
08:45 AM pfred1: Loetmichel shutting systems down is bad for them
08:46 AM pfred1: just the thermal expansion alone
08:46 AM sync: compiling is one of the things that get faster, but general response is just so much better
08:46 AM Loetmichel: pfred1: doesent matter
08:46 AM pfred1: of course it does hot and cold hot and cold
08:46 AM sync: and booting vms is so much faster
08:46 AM Loetmichel: bosses wife at the company switches off the lihgts when you go to the bathroom. she would throw a hissy fit seeing a PC running after hours
08:46 AM sync: my win10 vm comes up in something like 3s now
08:47 AM sync: but I need to upgrade soon, 64G of ram is not nearly enough
08:47 AM pfred1: I need to get more into virtulizing
08:47 AM Loetmichel: sync: win10... your own fault then.
08:48 AM sync: not really, I'm not going to use outdated software
08:48 AM pfred1: I use old software if it works
08:48 AM Loetmichel: either use win7 or use a real OS
08:49 AM pfred1: this terminal and IRC client are older than dirt
08:49 AM Loetmichel: anyone who uses win10 for anything productive is responsible for any pain he receives.
08:49 AM sync: there is no pain, it just works
08:49 AM Loetmichel: so why the upgrade to ssd and more than 64gb of ram then?
08:49 AM pfred1: I was watching a guy on the Tube yesterday running Linux in Windows
08:50 AM Loetmichel: denial is a form of coping... but not a very effektive one ;)
08:50 AM pfred1: was the worst Linux session I've ever seen but he seemed happy enough with it
08:51 AM sync: Loetmichel: because I run more than one vm
08:51 AM Loetmichel: Un a win10 host?
08:51 AM sync: and I don't want to wait longer for the vm to boot just because the spinning rust is limiting io performance
08:51 AM Loetmichel: whatfor?
08:51 AM pfred1: for the most part I like to go native
08:51 AM Loetmichel: get an ESXI box somewhere in the cellar and have a thin client on the desk
08:51 AM Loetmichel: problem solved for good
08:51 AM sync: it is not your business why I run more than one vm
08:52 AM pfred1: sync inception?
08:53 AM sync: no, my host is linux, but I need some stuff that runs on windows, so I just run it in a vm but I need acceptable performance in them so I need a system that delivers that
08:53 AM sync: and after a few years the machine I have is getting too slow
08:54 AM pfred1: yeah i know about too slow
08:54 AM Loetmichel: sync: you can run as much vms for any given reason. i dont care. The moment you complain about it NEEDING lots of ram and ssds you _are_ liable to get a dressing down for using an ineffctive and spying OS as a host though
08:54 AM pfred1: last year this machine seemed fine to me now not so much
08:55 AM Loetmichel: ah, so the win10 isnt the host at all
08:55 AM sync: yes.
08:55 AM sync: it would not matter tho
08:55 AM Loetmichel: then its ok
08:55 AM sync: I would need the same performance even if win10 would be the host
08:55 AM Loetmichel: no
08:55 AM sync: yes
08:55 AM pfred1: this took way too long http://i.imgur.com/Hj9r67a.jpg
08:55 AM Loetmichel: you would need about double that
08:55 AM sync: no
08:57 AM pfred1: my machine needs Psyco
08:57 AM Loetmichel: ... aside from tha fact that all the performance leaks you are paying for are because of the spying and "cloud drive" stuff that m$ insists on throwing your way if you use win10
08:58 AM Loetmichel: after win7 they simply dropped the ball completely.
08:58 AM pfred1: no they kept the ball
08:58 AM Tom_L: the ms has 10 on a laptop and it seems to run ok
08:58 AM Tom_L: what's really annoying is it's updates
08:58 AM Loetmichel: pfred1: ... and were going home?
08:58 AM Loetmichel: ;)=
08:59 AM pfred1: they hit their users with the bat too
08:59 AM Loetmichel: Tom_L: you men its "non-optional" and "enforced" updates?
08:59 AM Loetmichel: mean
08:59 AM Tom_L: yeah
08:59 AM Loetmichel: pfred1: indeed
08:59 AM pfred1: it's a goo thing Windows users love the abuse
09:00 AM Tom_L: i run 7 on all my winblows boxes
09:00 AM pfred1: there's plenty of abuse to go around in Linux these days though too
09:00 AM Tom_L: no os is flawless
09:00 AM Loetmichel: Tom_L: same here... i need to upgrade the company server one day though... win 2003 server is a BIT outdated...
09:01 AM pfred1: more like all OS is just a ball of warts
09:01 AM Loetmichel: .. but i have no time for that. And boss isnt willing to pay 5 figure for it to an external consultant for it
09:02 AM pfred1: Loetmichel your boss must think Ferrari tune ups are cheap or something
09:03 AM pfred1: ain't nothing cheap these days
09:03 AM Tom_L: not even that girl on the corner...
09:04 AM Loetmichel: i can relate to his chepness there though. i wouldnt pay 15kEur for a single win2003 server upgrade either.
09:04 AM pfred1: Loetmichel sure you would
09:05 AM Loetmichel: ... i would format the machine, put a linux on it and take a week to figure out how to migrate the data from the Mail server and the CRM to it
09:05 AM pfred1: Loetmichel if you were a celebrity with your own gambling site
09:05 AM Loetmichel: for THAT kind of money
09:34 AM miss0r: The other day I had to order 6m 25x25x2 stainless 316 square tube because my inventory was ~300mm sort for an order.... And now it turns out I miscalculated. I did have plenty *sigh* :)
09:35 AM miss0r: I guess that is just the stuff that happens
09:38 AM gregcnc: miss0r maho 400 https://www.youtube.com/watch?v=rnFhr1iwywE
09:38 AM MarcelineVQ: "too much stainless" doh ho ho
09:39 AM miss0r: gregcnc: sadly I use philips glass scale heads
09:41 AM pfred1: I hate to machine stainless welding stainless sucks too
09:41 AM pfred1: let's face it working with stainless sucks all around
09:41 AM pfred1: it is nice stuff though
09:58 AM * JT-Shop likes welding stainless
10:01 AM jym: JT-Shop: sheet?
10:01 AM Tom_L: now to figure out how to accurately drill all these holes
10:02 AM * jym hanfs Tom_L a hand cranked drill
10:02 AM jym: Tom_L: http://oldtoolheaven.com/hand_drills/drillimg/d3firstlg.jpg
10:03 AM jym: Tom_L: Or, if you want a modern version... https://www.coxhardware.com/images/Product/medium/14034.png
10:03 AM archivist: eggbeater
10:04 AM jym: Tom_L: Or, OLD OLD OLD school.. http://www.ancientegypt.co.uk/trade/explore/images/bowdrill.jpg
10:04 AM pfred1: JT-Shop you use TIG?
10:04 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_plate.jpg
10:04 AM jym: archivist: But which came first? the hand drill or egg beater?
10:05 AM Tom_L: those that aren't countersunk _are_ on the opposite side
10:05 AM pfred1: the rod for it is so expensive the guy at the supply house took pity on me and just gave me one
10:05 AM pfred1: he was like you don't want to buy a sleeve of these
10:05 AM jym: Tom_L: got a cnc router/mill?
10:05 AM Tom_L: not one big enough for all of em at once
10:05 AM pfred1: he didn't even tell me what they ost
10:05 AM pfred1: this was after I bought a box of aluminum electronics for $155 too
10:06 AM MarcelineVQ: pfred1: stainless is amazing to weld if it's not thin
10:06 AM jym: Tom_L: If you have a refernce pin, you could section it off?
10:06 AM pfred1: electrodes even
10:06 AM Tom_L: probably
10:06 AM Tom_L: i'm not sure the plate will fit on the sherline though
10:06 AM pfred1: MarcelineVQ I didn't liek it as much as mild steel
10:07 AM Tom_L: even doing it half at a time
10:07 AM MarcelineVQ: I'm told cast electrodes is where you get into trouble
10:07 AM MarcelineVQ: Never had the gumption to try them myself though, especially when you can just braze it
10:07 AM pfred1: cast iron?
10:07 AM MarcelineVQ: yeah
10:08 AM pfred1: I've had mixed success with cast sometimes it works sometimes it don't
10:08 AM Tom_L: you gotta preheat it no matter what you do to it
10:08 AM pfred1: it depends on the casting you're welding I think?
10:08 AM pfred1: Tom_L I've heard that
10:09 AM pfred1: when it works I don't bother preheating it
10:09 AM Tom_L: guys welding cast iron heads will sandbag them while heating
10:09 AM pfred1: I got a vise base here that got busted and I can't weld it
10:10 AM Tom_L: and keep it bagged until done welding
10:10 AM pfred1: once some kid brought me this cooked exhaust manifold and i couldn't weld it either the thing just seemed fried to me
10:10 AM pfred1: like it wasn't evne metal anymore?
10:12 AM pfred1: but I wended up a stand for a floor mixer for a bakery once and that went OK
10:12 AM pfred1: other than it smelling like donuts when I welded it
10:12 AM Tom_L: that's a problem?
10:12 AM MarcelineVQ: that's amazing
10:12 AM pfred1: it was pretty nasty
10:13 AM pfred1: like donuts that fell on the floor and then you cooked them
10:13 AM pfred1: I had ground it all out too but I didn't go wild cleaning it up
10:16 AM sync: miss0r: realistically it is more futureproof to just swap the scales
10:17 AM sync: the philips ones are huge, so you should be able to find some replacements for cheap
10:17 AM gloops: heat the casting up - use cast welding rods - cool it off slow
10:18 AM pfred1: gloopsif 6013 don't make it stick chuck it out
10:19 AM gloops: pfred for a lot of things it is kaput if the casting goes at a critical point - which it usually is
10:20 AM archivist: else take to Cast Iron Services and they will fusion weld with real cast
10:21 AM pfred1: archivist they probably want something for doing that though
10:21 AM gloops: dovetail it
10:21 AM archivist: loadsamoney
10:21 AM MarcelineVQ: at least 20 somethings
10:21 AM gloops: or chain tap the fracture
10:21 AM archivist: iirc our steam pipes cost around 600 quid
10:22 AM gloops: with a bow drill
10:25 AM gloops: http://metalcrackstitching.com/images/mcs8%20after.jpg < easy
10:26 AM gloops: you have to wonder, what cracked that
10:27 AM MarcelineVQ: time * use will do that to just about everything. loving the frankenstein aesthetic though
10:28 AM pfred1: gloops frankenmachine
10:28 AM gloops: well, cast has a lot of strength, but cant take a shock - somebody whacked it
10:29 AM pfred1: wow I found a picture of that old drill press
10:30 AM pfred1: it is in /home/giga/buck/Documents/OldCrap/www/wood/cshop/OldShopPix/p3040004.jpg
10:30 AM pfred1: I mean where else would I keep it?
10:31 AM gloops: oldcrap
10:31 AM MarcelineVQ: obviously
10:31 AM pfred1: imminently logical if you think about it
10:32 AM pfred1: that's one problem with Linux you will end up with files from deades ago eventually
10:33 AM pfred1: Windows will happily lose your data for you regularly which over time is a huge plus
10:35 AM pfred1: Linux holds onto bits and bytes like they actually mean something though
10:38 AM archivist: win2k never lost much if anything
10:40 AM pfred1: that's cool when Windows goes tits up it often takes everything with it
10:40 AM pfred1: and Windows used to like to go tits up a lot
10:41 AM pfred1: I know when i ran Windows I was constantly losing data
10:41 AM pfred1: but I hear it has improved somewhat
10:41 AM pfred1: I haven't run Windows since 1996
10:42 AM archivist: about 6 months since I ran the win2k box
10:43 AM pfred1: I got a box here that I retired and while it sat something died in it so now it cn't mount the drives anymore there's crap on it that I lost
10:43 AM pfred1: but I can't really blame Linux for that loss
10:44 AM pfred1: I could probably take those drives out and run them in something else? but I don't have any machines running that do ide now
10:44 AM archivist: just move drives to linux box, recover files
10:44 AM pfred1: yeah i don't have machines that can read those drives
10:44 AM pfred1: everything is sata now
10:44 AM archivist: use a usb caddy that holds ide
10:44 AM pfred1: I would if i had one
10:45 AM pfred1: I don't think it is anything important before i laid tht machine up I pulled whatever was good off it
10:45 AM pfred1: I was going to use it as a PDF reader that's how i found out it is dead
10:46 AM pfred1: so I could look at PDF files while I was building circuits at my bench
10:46 AM pfred1: I had it all planned out
10:46 AM pfred1: then the machine wouldn't run
10:47 AM pfred1: this machine will end up there eventually now when I get my new PC
10:53 AM JT-Shop: https://www.amazon.com/Bipra-SATA-Adapter-Power-Drive/dp/B001A5SK56
10:54 AM pfred1: JT-Shop doesn't Jeff bezos have too much money already?
10:54 AM JT-Shop: dunno who that is
10:54 AM pfred1: he owns Amazon
10:55 AM pfred1: he's also the richest man in the world at the moment too
10:55 AM JT-Shop: https://www.amazon.com/Sabrent-5-25-INCH-Converter-Activity-USB-DSC9/dp/B00DQJME7Y
10:55 AM JT-Shop: slid past Bill?
10:55 AM pfred1: he's also a rabid liberal too
10:55 AM pfred1: yeah just a few months ago
10:56 AM pfred1: he woke up the richest man on the planet
10:56 AM pfred1: he owns the washingmachine post
10:56 AM JT-Shop: damn a net worth of 90.6 BILLION dollars
10:57 AM pfred1: I know too much about Jeff Bezos!
10:57 AM pfred1: yeah he's a frigging scumbag
10:59 AM pfred1: alibaba sold more than 25 billion in merchandise yesterday
11:00 AM pfred1: on singles day
11:00 AM pfred1: I bet Jeff wishes he did that
11:01 AM pfred1: I got to admit the way this guy looks creeps me out https://www.theverge.com/2017/11/11/16637362/alibaba-singles-day-2017-sales-record-online-shopping-black-friday-cyber-monday
11:02 AM pfred1: he's deep in the uncanny valley with that face
11:02 AM miss0r: sync: arguably its not very future proof to run a CNC from '86 at all ;)
11:02 AM pfred1: miss0r we thought we were in the future in 1986
11:03 AM pfred1: with our big hair!
11:03 AM miss0r: hardly. I was born a year later ;)
11:03 AM gonzo_: quicky meas question for you nice people... Getting odd joint following errors on x/y/z, when starting the spindle. But I'm not moving the axis, just starting spindle. And I have steppers for the axis, so the feedback is all in sw. So can't see how the motion prog thinks they are moving
11:04 AM pfred1: I was 22 in 86
11:04 AM gonzo_: wondering is the feedback is in the mesa board and that is getting glitched by spindle VFD noise?
11:04 AM archivist: electrical noise
11:04 AM pfred1: living large and in charge
11:04 AM miss0r: gonzo_: ...
11:04 AM miss0r: What archivist said
11:04 AM pfred1: noise is a big issue with CNC
11:05 AM archivist: screen the vfd to motor, endure proper grounds etc
11:05 AM gonzo_: is the positional feedback for a dead reconning stepper system, done through the mesa?I had assumd it was in the pc
11:05 AM archivist: ensure
11:05 AM pfred1: archivist that's what people ay but I always have to take more proactive measures to combat EMI
11:05 AM archivist: we dont know what inputs you have
11:05 AM gonzo_: I have opto for everything from the mesa to the machine
11:06 AM pfred1: opto is good
11:06 AM gonzo_: so only path must be through the mains
11:06 AM pfred1: could be
11:06 AM gonzo_: trying to work out what is getting gittched
11:06 AM pfred1: a lot of stuff uses ferrite beads to squealch noise
11:06 AM pfred1: its a crap fix
11:07 AM pcw_home: What kind of hardware? A following error on a stepper system probably means you have a EMI generated data read error from the FPGA card
11:07 AM gonzo_: pcw_home, ah, just the man!
11:07 AM pfred1: yes he is
11:09 AM gonzo_: I may have answered my own question here.... I get the position from hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-fb
11:10 AM gonzo_: so I assume that means that the dead reconning of where the stepper has got to, is from the meas card
11:10 AM pcw_home: yes
11:10 AM gonzo_: so looks like I'm EMI'ing the fpga
11:11 AM archivist: or cables
11:11 AM pcw_home: Not the FPGA, the connection from the FPGA to the host
11:11 AM pcw_home: what hardware?
11:12 AM gonzo_: I have a 7190, interfaced on the parallel port of the pc
11:12 AM gonzo_: opto's for everything from the 7i90 to the machine/vfd/stepper drives/pendant
11:13 AM pcw_home: The EPP cards are the most susceptible to this kind of interference
11:14 AM pcw_home: I would try rerouting /shortening the EPP cable and making sure there are no possible ground loop
11:14 AM gonzo_: I thought that the protocol between the PC and 7i90 would have sorted the errors?
11:14 AM pcw_home: it may require a line filter on the PC and or VFD
11:15 AM gonzo_: I have a big arsed filter for the VFD, but not fitted yet. Still at the trial stage oif the build
11:16 AM gonzo_: cheers for the info. I know where to look now.
11:17 AM pcw_home: noise susceptibility goes up exponentially with cable length so if you can shorten the cable that's often the easiest fix
11:17 AM pcw_home: bbl
11:18 AM archivist: wires being antennas
11:18 AM archivist: also use a screened parallel cable
11:21 AM gonzo_: Yep, the machine/drive side is electrically robust. But the PC side was just thown together
11:38 AM IchGucksLive: hi
11:44 AM gloops: evening Ichs
11:44 AM IchGucksLive: ;-)
11:44 AM IchGucksLive: 10 more abos today on YT
11:44 AM IchGucksLive: and question on question
11:44 AM gloops: abos whats that?
11:45 AM IchGucksLive: people who follow the channel
11:45 AM IchGucksLive: does someone know if the Nativ cam is already on the download DVD image
11:46 AM IchGucksLive: and maybe also connected to a sim mashine
11:54 AM IchGucksLive: gloops: more and more videos now on the interface at it gots so many hits on YT
11:55 AM IchGucksLive: never mind
11:55 AM gloops: yes good luck with the youtube side of things Ichs
11:56 AM pfred1: IchGucksLive you have a YouTube channel?
11:56 AM IchGucksLive: there will be a day as i delete everything as i did more then one bevore
11:56 AM IchGucksLive: even on 1mio hits
11:57 AM IchGucksLive: pfred1: https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
11:58 AM pfred1: hehe
11:58 AM pfred1: I'm watchng your German video
11:58 AM IchGucksLive: there are so many english ones
11:58 AM pfred1: it's scary I almost understand it
11:59 AM IchGucksLive: then you are cnc pro
11:59 AM pfred1: no i just know some German
11:59 AM IchGucksLive: as so many in the usa
12:00 PM pfred1: when English is yoru first language it is hard to get motiated ot learn some foreign language
12:00 PM pfred1: I'll say this for the Brits they sure spread English around
12:01 PM IchGucksLive: isent there a MUST in school
12:01 PM IchGucksLive: only you can if you want is bad
12:01 PM pfred1: Grman is a root language of English too
12:02 PM IchGucksLive: spanish is best in south states
12:02 PM IchGucksLive: wher french is popular in northwest
12:02 PM pfred1: French isn't popular here
12:03 PM pfred1: that's more of a canada thing
12:03 PM IchGucksLive: thats why canadians are welcome and good paid
12:07 PM pfred1: IchGucksLive what did you use to generate the toolpaths in this video https://www.youtube.com/watch?v=TSvDz0gIbOY
12:07 PM IchGucksLive: estlcam
12:08 PM pfred1: I never heard of that one
12:08 PM IchGucksLive: best fotr this sort of toolpath V-carve
12:08 PM IchGucksLive: it is almost free
12:08 PM IchGucksLive: takes only some seconds to do path
12:08 PM pfred1: I did like how it did the roman serif strokes
12:10 PM pfred1: I was using a router as a spindle on my machine but i couldn't hack the noise it made
12:10 PM pfred1: routers get to be a bit much after they've been running a while
12:10 PM pfred1: some CNC jobs can take a really long time to run too
12:11 PM IchGucksLive: pfred1: some example http://heimwerkermarkt-tretter.de/hs.jpg
12:11 PM pfred1: IchGucksLive they'
12:11 PM pfred1: IchGucksLive they're nice
12:11 PM IchGucksLive: http://heimwerkermarkt-tretter.de/hs_2.jpg
12:12 PM pfred1: I've made a lot of signs but by hand
12:12 PM pfred1: one reason I made my CNC was to get it to route signs for me
12:13 PM sync: just wear ear protection and listen to sick wobs while the machine runs
12:14 PM pfred1: sync yeah I wear ear protection when I do some things i should use it more
12:14 PM pfred1: but my hearing is shot now
12:14 PM pfred1: It is a good thing the whistling doesn't bother me
12:15 PM pfred1: I could give up my present project and just use this as a bracket holder for this router on my CNC
12:16 PM pfred1: https://i.imgur.com/Y6WSMdL.jpg
12:16 PM pfred1: I was going to make a plunge router base our of thaat
12:16 PM pfred1: out of that even
12:17 PM pfred1: right now I could adapt it as a spindle holder for my CNC pretty easily though
12:18 PM pfred1: easier than finishing it as a plunge router base
12:19 PM pfred1: I only have a 6mm collet for that router though which kind of sucks they want like $20 for the 1/4" collet for it
12:19 PM gloops: what material is that?
12:19 PM pfred1: that's home baked HDPE
12:19 PM pfred1: was water bottles
12:19 PM gloops: ahh ok
12:19 PM gloops: home baked - how do you do that?
12:20 PM pfred1: it was one of these blocks http://i.imgur.com/K4lNH7B.jpg
12:20 PM pfred1: you put the HDPE in an oven and melt it down
12:20 PM gloops: hey that looks pretty decent stuff
12:20 PM pfred1: yeah it's great
12:20 PM pfred1: slippery as hell
12:21 PM pfred1: well there's two kinds of HDPE there's the translucent and the colored stuff
12:21 PM pfred1: the colored stuff has additives in it
12:22 PM gloops: upvc window frames melt well
12:22 PM pfred1: plastic buckets are colored HDPE
12:22 PM pfred1: you can melt those down into stock blocks too
12:22 PM IchGucksLive: grease stone
12:23 PM pfred1: if you can find a sign company and get cut offs HDPE scrap is practically worthless
12:23 PM gloops: yeah - nearly all plastic is marked
12:23 PM IchGucksLive: cool to mill but you need water to cool the tool
12:23 PM pfred1: they don't even get 2 cents a pound for it
12:23 PM IchGucksLive: i use alot of SIKA/Necuron
12:23 PM IchGucksLive: Ureol
12:23 PM pfred1: it's hardly worth picking up for what they get
12:24 PM IchGucksLive: you can go as fast as the bit takes
12:24 PM pfred1: yeah the stuff cuts like a dream
12:24 PM pfred1: I call it fantasy machining
12:24 PM miss0r: Damn these welding gloves are not quite rated for tig... :D
12:24 PM IchGucksLive: pfred1: see https://www.youtube.com/watch?v=sqx9w80diKo my sculping
12:25 PM IchGucksLive: on a 0,4backlash chees
12:25 PM IchGucksLive: as well as a 1deg off 15USD 27.76gear
12:25 PM pfred1: IchGucksLive what are you using to make the G Code to do that?
12:25 PM miss0r: IchGucksLive: Looks nice on the video
12:26 PM IchGucksLive: pfred1: deskproto
12:26 PM pfred1: is that the grand Nagus?
12:26 PM IchGucksLive: Venus of milo
12:27 PM IchGucksLive: i got also beethoven !
12:27 PM IchGucksLive: and it makes alot of dust
12:27 PM pfred1: I think I have the Chinese knock off of that router
12:28 PM pfred1: mine sounds a lot like this one does sped up too
12:28 PM pfred1: the bearings in it are super shot now
12:28 PM IchGucksLive: this is the A Axis https://www.ebay.de/itm/DE-Ship-27-1-Planetary-Gearbox-Nema-17-Stepper-Motor-0-4A-DIY-CNC-Robot-Camera-/23165760

12:29 PM pfred1: I always wanted to get a rotary table for my mill
12:29 PM pfred1: so often I could use one
12:30 PM IchGucksLive: use a cheep NSK
12:33 PM IchGucksLive: pfred1: https://www.ebay.com/itm/NEMA23-030-Worm-Gear-Reducer-Ratio-10-1-15-1-30-1-56B14-1400r-min-Speed-Reducer/122401339155
12:34 PM pfred1: I have something like that sitting on a motor in my meth lab
12:34 PM pfred1: I've often thought about popping it off and trying to make some kind of a rotary positioner out of it

12:37 PM pfred1: I wonder why people are watching the auction?
12:38 PM IchGucksLive: lots you can do with this things
12:42 PM IchGucksLive: synfinatic: online ?
12:42 PM synfinatic: IchGucksLive yep
12:42 PM IchGucksLive: and did you find things in your near
12:44 PM synfinatic: so i know about techshop which is a local maker space. i have an ex-coworker I'm trying to meet up with an pick his brain
12:44 PM IchGucksLive: thats what i told you
12:45 PM IchGucksLive: in the us MS is most comen but its crap on cnc stuff
12:45 PM IchGucksLive: even if 9800people a week go that way
12:46 PM synfinatic: techshop/maker spaces are cool, but i'd much rather have the tools in my garage and not have to drive down there every time I want to do something.
12:47 PM IchGucksLive: maybe they will fine you as you make them better parts
12:47 PM pfred1: synfinatic yeah but it is hard to have every tool
12:47 PM synfinatic: i mean, right now I'm watching motorcycle racing on tv from my couch while kicking off a print on my 3d printer. hard to do that when things are 15min away :)
12:47 PM synfinatic: pfred1 that is true
12:48 PM gregcnc: you can have every tool but then you end up with a mill in your kitchen
12:48 PM IchGucksLive: ok m off for today GN( from snowing germany
12:48 PM pfred1: or you just have a really big outbuilding
12:48 PM pfred1: my garage is packed now
12:48 PM synfinatic: i have a 2 car garage and i'm actually adding on another 80sqft right now
12:48 PM pfred1: I passed on a nice bandsaw for $50 because i couldn't think of where I'd put it
12:48 PM IchGucksLive: gregcnc: like me no more space to many routers http://tv-profi-gmbh.de/masch_baumh_k.jpg
12:49 PM synfinatic: decent space, not a lot of space
12:49 PM pfred1: I have a 1 1/2 car garage
12:49 PM pfred1: it is 20x20
12:49 PM pfred1: when I started it seemed big now i can't turn around in it
12:50 PM synfinatic: right now I have a lift for my motorcycle, so that takes up a fair bit of space
12:50 PM pfred1: yeah I ain't getting a motorcycle in here
12:50 PM pfred1: unless i bring it in in pieces
12:51 PM gregcnc: I don't even know why I look for machines on CL, there is nowhere to put anything else
12:51 PM pfred1: I think if my shop was twice as big as it is now I'd have enough room
12:52 PM pfred1: I'm still kicking myself for passing on that bandsw i saw but I couldn't think of where I'd put it
12:52 PM pfred1: when I went back to that sale someoen scooped it up it was cherry
12:52 PM pfred1: one of those 16" throat jobs
12:53 PM gregcnc: vertical?
12:53 PM pfred1: they go for about $350 or so new?
12:53 PM pfred1: grizzley jet they all make one
12:53 PM pfred1: I think the one I was looking at was a jet?
12:53 PM pfred1: it was cream colored
12:55 PM gregcnc: probably jet. any metal cutting band saw for 50$ is a steal
12:56 PM pfred1: this was a wood one I have a 4x6
12:56 PM pfred1: I suppose it'd have cut metal too with the right blade on it
12:57 PM pfred1: yeah it had real low miles only one owner guy didn't use it much
12:57 PM gloops: any good archivist - https://www.ebay.co.uk/itm/Manual-Vertical-Milling-Machine/232559354135?
12:57 PM pfred1: it was basically new
12:57 PM gregcnc: I paid 50 for an ancient delta 14" wood/metal a few years ago. The guy was surprised I wanted it
12:57 PM synfinatic: so are any of the mini mills worth serious consideration? as you guys point out, space is a concern
12:57 PM pfred1: old Delta is good
12:58 PM pfred1: I have a Delta scroll saw and a Delta dedicated mortising machine
12:58 PM pfred1: I almost bought a Hawk scroll saw once
12:59 PM MarcelineVQ: gloops: interesting design, looks similar to a converted drill press
12:59 PM pfred1: they only wanted $200 for it but I don't scroll enough anymore to justify the purchase
12:59 PM pfred1: new Hawks go for $1,200 or so
12:59 PM pfred1: they're supposed to be the scroll saw
01:01 PM pfred1: apparently they have 2 models a $1,200 one and a $1,400 one
01:02 PM gloops: Marcel tis a bit different
01:02 PM gloops: think it was always a mill though
01:03 PM miss0r: I need to get a proper ventilation system in here. it sucks going outside to do the acid cleaning of the welds
01:03 PM miss0r: Its cold outside, which in turn means the acid works slower :-/
01:03 PM sync: you can use electrolysis
01:04 PM pfred1: miss0r it got cold here
01:04 PM gloops: freezing here tonight, coldest night this year
01:04 PM miss0r: sync: Yeah. but I don't have the room to fit most the stainless I weld.
01:04 PM pfred1: I remember trying to degrease a car engine one winter and thinking the degreaser I was using sucked
01:04 PM pfred1: it was just too cold
01:05 PM pfred1: later that year when it was warmer i used the other half of the bottle and it worked OK
01:06 PM gloops: steamer
01:06 PM sync: well, you don't really need room for an electrolysis machine
01:06 PM sync: just a dc supply and a carbon brush
01:06 PM miss0r: I have a pressurewasher that heats up the water to 150c, and basically explodes with steam when it exits the nozzle. Quite an effective system
01:06 PM pfred1: sync electrolysis? you removing hair?
01:07 PM gloops: that sounds useful miss0r
01:07 PM pfred1: yeh my pressure washer is cold
01:07 PM sync: no, removing oxides off stainless
01:08 PM gregcnc: citric acid base is common
01:08 PM miss0r: This is the 4 welded 'arms' for holding the inductive switches: http://picpaste.com/IMG_20171112_200544-fzeBOsFs.jpg
01:09 PM miss0r: They are too big for me to do electrolysis on :) I'd need a HUGE tank :) (the scale is 2meters long)
01:12 PM pfred1: you can make a big tank with a frame and a tarp
01:12 PM gregcnc: https://www.1stopweldingshop.com/Catalogue/Welding-Cutting/Weld-cleaning-Polishing
01:12 PM pfred1: people have derusted RVs in swimming pools
01:12 PM miss0r: I used to clean the welds with a stainless wire brush. It took forever to get a poisones chemicals level one certificate, so I could legally buy the acid needed for this
01:12 PM miss0r: gregcnc: yeah :D I looked at one of thoes at one point. But I don't weld nearly enough in here to justify owning one
01:12 PM gregcnc: there is probably a cheapo way of doing that
01:12 PM pfred1: what the hell is that?
01:12 PM sync: yeah, just using a powersupply and a carbon fiber brush
01:12 PM sync: you don't even need HF for them
01:12 PM miss0r: rehehehehehealy?
01:12 PM sync: yes
01:12 PM * miss0r will look into that
01:13 PM miss0r: Sounds promising
01:13 PM pfred1: so it cleaned that brown in the second picture?
01:13 PM pfred1: or does it leave tha brown?
01:13 PM gloops: wow 10 cutters for £6 suitable for carbon steel https://www.ebay.co.uk/itm/10x-Tungsten-Carbide-4-Flute-HSS-End-Milling-Cutter-Slot-Drill-Bit-Set-1-5-10mm/192253391061?
01:14 PM pfred1: they were dirt cheap yesterday on singles day
01:14 PM gregcnc: thats some of that newfangled "Tungsten carbide HSS"
01:14 PM pfred1: yeah they'er not tungsten
01:15 PM pfred1: I need a new collet set for my mill
01:15 PM pfred1: I have this wacky style
01:16 PM gloops: cant see them being any good for that price anyway
01:16 PM gloops: Note:
01:16 PM gloops: Please allow 1-3mm error due to manual measurement.
01:16 PM pfred1: they're not really center cutting
01:16 PM miss0r: :D hahaha
01:16 PM pfred1: they're the kind with the hole in the center
01:17 PM miss0r: also; the specs list them as HSS
01:17 PM pfred1: but if you run an adaptive cut i guess it doesn't matter
01:17 PM pfred1: they're definitely HSS
01:17 PM pfred1: not very good HSS either
01:17 PM miss0r: "10x Tungsten Carbide 4 Flute HSS End Milling Cutter" lol
01:18 PM miss0r: If that ain't a bunch of generic chinesium sales wank, I don't know what is :D
01:18 PM gloops: theyre fine for hdpe
01:18 PM miss0r: Sure
01:19 PM gloops: be ok for ally
01:19 PM miss0r: perhaps
01:19 PM miss0r: (only judging from the picture) the grind on the cutting edges lookds sketchy at best
01:19 PM gregcnc: if they are actually sharp. Once you get past the point of breaking tools doing dumb things it's simply not worth buying the junk
01:20 PM pfred1: gregcnc some of the junk ain't bad
01:20 PM gregcnc: OK
01:21 PM pfred1: I ain't doing aerospace work over here
01:21 PM miss0r: If you want cheap and good cutters, have a look at: http://www.precisebits.com/
01:21 PM miss0r: I got some great stuff there
01:22 PM pfred1: I do OK with Chinese junk for the most part
01:22 PM miss0r: I just couldn't do that no more!
01:23 PM miss0r: i got some realy nice HSS TiN 60 degree cutters from that link. I use thoes for PCB milling. Best results i have gotten with any cutter
01:23 PM gloops: https://www.ebay.co.uk/itm/Round-Spiral-Aluminum-Heat-Sink-Radiator-90x10mm-For-10W-LED-High-Power-Lamp/192253316295? < could be useful
01:24 PM miss0r: How the hell can they sell it at thoes prices? :S
01:25 PM pfred1: so far I've isolation routed with some 20 degree carbide Vee bits
01:25 PM DaViruz: miss0r: starving child labor
01:25 PM gregcnc: it's scrap
01:26 PM miss0r: Its still amazing. Also the fact that you can have it shipped for next to nothing if you can wait a month
01:26 PM miss0r: Its hard for guys like us to compete with
01:26 PM pfred1: that isn't an extrusion?
01:26 PM gregcnc: shipping is due to international postal agreements, you pay for it in your own postal system
01:26 PM gloops: yeah that is the real question - how can WE sell at these prices
01:27 PM gloops: https://www.ebay.co.uk/itm/Set-of-3-4-5-6-8-10-12-14-16mm-Straight-Shank-H8-HSS-Reamer-Chucking-Drill-Bit/192299198404? 10 reamers £10
01:27 PM gloops: you could buy the steel here for that to make them
01:27 PM gloops: couldnt
01:28 PM gregcnc: If they actually work they might be a good deal, don't exspect them to be anythign like a real reamer
01:28 PM pfred1: gloops that is because westerners are too greedy
01:28 PM pfred1: I worked in a tool and die shop here
01:28 PM pfred1: the boss would burn like $1,200 of gas in his speed boat in a day
01:28 PM gloops: pfred they do this until our industry is closed - then they sell for real money
01:28 PM pfred1: he was a scumbag
01:29 PM miss0r: gregcnc: I hear'ya. I wouldn't want to buy a H8 reamer with the specification mentioning you should allow for 1-3mm size difference, due to measurements :D
01:29 PM gloops: this is dumping
01:29 PM gregcnc: Carbide reamers from china cost as much a real USA reamers
01:30 PM miss0r: bleh... USA reamers :ş Buy swiss & german made reamers if you want something good
01:30 PM miss0r: metric & good that is ;)
01:30 PM gloops: you cant buy a bolt that size for £1 lol
01:30 PM gregcnc: https://www.ebay.com/sch/standardcuttingsolutions/m.html
01:31 PM pfred1: miss0r our units are based on what metric was supposed to be based on
01:32 PM gloops: i got a box of old reamers, nice quality, hardly ever use them but wouldnt let them go
01:32 PM miss0r: pfred1: https://www.youtube.com/watch?v=r7x-RGfd0Yk
01:32 PM miss0r: haha
01:33 PM miss0r: jump to 35 sec
01:33 PM pfred1: miss0r we don't use the Imperial system
01:33 PM pfred1: we never did
01:34 PM miss0r: I know :] Our conversation just made me think of that video
01:34 PM pfred1: we use US Customary units
01:34 PM pfred1: which Thomas Jefferson devised after attending the metric conference
01:34 PM pfred1: thn you idiots went another way
01:35 PM miss0r: Yeah. Sorry about that ;)
01:35 PM pfred1: the standard was supposed to be the period of a pendulum swing
01:35 PM gregcnc: that was fun
01:36 PM pfred1: but you guys decided ot use a cocked up measurement of the planet
01:36 PM pfred1: whih to this very day doesn't work out
01:37 PM gregcnc: what sucks is inputting radius of fractional tools into your metric CNC control
01:37 PM pfred1: I believe it is off by about 20 kilometers?
01:37 PM miss0r: pfred1: Wha? :S
01:38 PM DaViruz: i'm sure the rest of the world will change to us customary units in the long run
01:38 PM gregcnc: very soon even
01:39 PM pfred1: DaViruz they use it now they just don't know it
01:39 PM gregcnc: i think jamaica is an early adopter
01:39 PM pfred1: 13mm drives are really a half of an inch
01:39 PM DaViruz: what utter crap
01:40 PM miss0r: hahaha
01:40 PM pfred1: the 5.56 is a .223
01:40 PM gregcnc: almost
01:41 PM DaViruz: calibers are a great example where the us system shines
01:41 PM pfred1: the 7.62 is 30 O 6 isn't it?
01:41 PM pfred1: ma deuce ain't converting though!
01:44 PM chopper79: I am going to be using a fixed position tool setter location on one of my machines. Probing a tools from .125" - .5" are no issue. The ones I am going to have problems with are my 2" face mill and other large diameter tools. I need to offset my X it seems to be able to probe down and touch the insert and not the center of the cutter body automatcally during the tool probing routine. How is this usually handled or does anybody have a link where I can rea
01:44 PM gregcnc: huh I don't know enough about caliber, who knew .380 ACP was 9x17
01:46 PM pfred1: Sammy Hagar - I Can't Drive 55 https://www.youtube.com/watch?v=RvV3nn_de2k
01:47 PM gregcnc: chopper79 I think they probe diameter from the side first if fully autopmated
01:48 PM Tom_L: chopper79, gonna be hard to do on an insert cutter unless you plan to orient the spindle too
01:48 PM Tom_L: maybe you can read the tool diameter from the tool table in your probe routine and offset it
01:48 PM gregcnc: that guess was wrong
01:48 PM gregcnc: right
01:48 PM chopper79: I would just turn the spindle by hand after changing my tool so the insert is able to be picked up by setter.
01:49 PM gregcnc: low RPM and backward is what I thought I've seen
01:49 PM Tom_L: never seen a cutter turning while probing it's length offset
01:50 PM sync: you always do that
01:50 PM sync: to check for a broken edge
01:50 PM sync: you rotate them in reverse tho
01:50 PM Tom_L: manually yes
01:50 PM chopper79: Probing from side is not an option for me. I was hoping that I could somehow just say that my 2" cutter was always tool 20 and the probing position is X positon offset.
01:50 PM sync: no
01:50 PM sync: not manually, the probing cycle does it
01:51 PM Tom_L: i set mine using the tool table, not individually so i'm not sure
01:51 PM gregcnc: https://www.youtube.com/watch?v=J7dCwBkUNNU.
01:52 PM pfred1: this guy has a lot of buttons
01:52 PM Tom_L: standard haas control
01:52 PM Tom_L: the vo-tech lab here is full of em
01:52 PM Tom_L: simulated
01:53 PM sync: lame
01:53 PM Tom_L: they get free haas machines too
01:53 PM gregcnc: free?
01:53 PM Tom_L: not so lame
01:53 PM pfred1: that's it. That's probing your tool!
01:53 PM Tom_L: in return haas gets to bring clients in to see them
01:54 PM sync: I'm not so sure what to think about machine simulators, we always just worked on real ones
01:54 PM pfred1: I feel button challenged now my machine only has 2 buttons and a switch
01:55 PM Tom_L: i don't know how much they use em, but i'm sure it's helpful
01:55 PM sync: and I'd rather see a heidenhain or siemens control being teached to someone, at least here they are significantly more common
01:56 PM pfred1: this is one of the goofiest vdeos
01:56 PM gregcnc: Less so here
01:56 PM sync: although the controls are quite the same after all
01:56 PM sync: fanuc are also common but nobody should ever use those
01:57 PM gregcnc: lol
01:57 PM chopper79: The probing routine would behave correctly for all tools besides the large diameter tools due to diameter of sensor. So how would the probing routine know if I had a 2" tool in verse a .25" tool so it would probe the tool correctly? I could set the tool table with the diameters, but the routine still would not know that the X needs to be offset by X amount so the insert hits the sensor. Would I need to different probe routines?
01:58 PM gregcnc: probe routine would include some form of radius compensation I suppose
02:01 PM gregcnc: this company has a huuuge touchscreen http://www.element-cnc.com/cyclone
02:01 PM gregcnc: on their control
02:02 PM pfred1: tune in next week when we discuss the ins and outs of pocket pool
02:07 PM Tom_L: gregcnc, bigger than the table
02:07 PM gregcnc: yeah, Datron is going that way too
02:08 PM Tom_L: fewer physical buttons to wear out
02:09 PM DaViruz: it wears you out mentally instead :(
02:09 PM Tom_L: it could be half that size and be just fine though
02:14 PM sync: does it DaViruz? I know lots of people like buttons but realistically you don't type a lot on the screen
02:16 PM DaViruz: i have yet to use a touchscreen that left me feeling it was a pleasant experience
02:17 PM DaViruz: maybe i'm just a bitter old man :)
02:17 PM sync: capacitive touch is works well
02:17 PM sync: eh -is
02:18 PM pfred1: I don't like screen smudges
02:19 PM pfred1: so that pretty much rules touch screens out with me
02:24 PM sync: they are glossy anyway, so pfft
02:30 PM pfred1: glossy doesn't bother me as long as there's no glare in fact glossy screens are best matte just blurs the image
02:31 PM pfred1: ever take a flat screen apart?
02:31 PM pfred1: there's usually a nice chunk of plastic in the screen
02:32 PM pfred1: it is abotu a quarter of an inch thick and the size of the sreen
03:15 PM JT-Shop: damn plasma pc is acting weird
03:15 PM MarcelineVQ: had it for awhile?
03:16 PM JT-Shop: it's an AMD E-450
03:17 PM JT-Shop: screen keeps locking up and sometimes it
03:17 PM JT-Shop: s just axis
03:17 PM MarcelineVQ: :(
03:17 PM Tom_L: done any updates to upset it?
03:18 PM Tom_L: time to wiggle all the connections
03:18 PM JT-Shop: fresh install of Debian and before that Linux Mint
03:18 PM JT-Shop: odd the mouse still works all the time
03:18 PM Tom_L: memory issue?
03:19 PM JT-Shop: dunno what would cause it
03:19 PM JT-Shop: last error was a latency error with something from the 5i25 telling me to check a pin
03:35 PM pcw_home: JT-Shop watchdog bite?
03:35 PM JT-Shop: no
03:38 PM JT-Shop: runs fine with ubuntu 10 and 2.7.x
03:39 PM pcw_home: ( trying to think what other hm2 error would be latency related )
03:56 PM pfred1: check your ground
04:10 PM Deejay: gn8
04:21 PM JT-Shop: is the H81M-S2H GSM good mb for uspace?
04:23 PM JT-Shop: so no problem with ubuntu 10, RTAI and LinuxCNC 2.7.x... the screen lock ups happen with mint, debian uspace and master... I think I'll try 2.7 with debian and uspace to see if that makes a differenc
04:23 PM JT-Shop: e
04:39 PM XXCoder: disconnect and reconnect display dont reset display?
04:44 PM JT-Shop: didn't try that but the display is dumb AFAIK
04:44 PM JT-Shop: makes me think the on board video is flaking out on me
04:45 PM XXCoder: that could happen. my cnc computer has onboard networking and card networking also
04:45 PM XXCoder: because onboard one startered jabbering and messed with entire network
04:52 PM JT-Shop: I think I'll just get another H81M-S2H GSM and toss that in the latency is amazing
04:53 PM XXCoder: nice
04:54 PM JT-Shop: and get a low profile case cause space is a premium on the plasma desk or spot as it is
04:57 PM JT-Shop: I wonder if I have any DDR3 SDRAM
05:00 PM JT-Shop: chicken door closes at 5:22 tonight
05:00 PM Tom_L: 22 min
05:01 PM JT-Shop: yup
05:01 PM Tom_L: i wonder if i should trust these cad models or wait til parts in hand to drill these plate holes
05:02 PM JT-Shop: they are jocking for positions now on the roost
05:02 PM JT-Shop: chinlee stuff?
05:02 PM Tom_L: yeah
05:02 PM Tom_L: fairly common though
05:03 PM Tom_L: it's going to be a close fit but i think i'll be ok
05:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/XY_Rail_Mount.jpg
05:04 PM Tom_L: if i put the screws in on assembly i should have room to tighten stuff ok
05:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/XY_Rail_Mount2.jpg
05:04 PM Tom_L: having the slides cross over the bottom ones
05:05 PM JT-Shop: looks nice
05:05 PM Tom_L: making a few changes as i go
05:05 PM Tom_L: i think with the slides spaced further apart on X it will make it more rigid
05:06 PM Tom_L: a little less travel but still should be ~15" or so
05:06 PM Tom_L: maybe as much as 18
05:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_plate.jpg
05:07 PM Tom_L: just gotta make sure i get the recess on the right side for each hole
05:07 PM JT-Shop: lotta holes :)
05:07 PM Tom_L: yeah
05:08 PM Tom_L: 1/2" alum plate should be plenty strong for this
05:08 PM JT-Shop: watch the plate doesn't warp after all the holes
05:08 PM JT-Shop: what kind of aluminum?
05:08 PM Tom_L: yeah i know
05:08 PM Tom_L: i'm not sure but i think it's probably 6061 or something like that
05:08 PM JT-Shop: Mic6 won't warp as it is cast
05:08 PM Tom_L: maybe 70 series
05:09 PM Tom_L: some of their stuff isn't marked that well
05:10 PM Tom_L: i saw some ~18" round bar there the other day
05:11 PM Tom_L: you could probably turn a set of rims from it
05:13 PM JT-Shop: rims are made from cast aluminum
05:14 PM JT-Shop: a good source for casting
05:25 PM JT-Shop: door down and locked time to head inside
06:00 PM Contract_Pilot: Back.... what a day...
06:01 PM Contract_Pilot: I think I got my game plan on going 3phase steppers on the lathe
06:01 PM Contract_Pilot: + Sold 2 of the DM8010 Drives on Fee-bay
06:01 PM Contract_Pilot: I got 2 left.
08:38 PM BeachBumPete: Evening folks :)
08:45 PM Tom_L: what's up?
08:46 PM XXCoder: hey homeless beach
08:47 PM BeachBumPete: Hey Tom howzitgoin
08:47 PM Tom_L: good
08:47 PM BeachBumPete: workin on some parts here editing programs etc
08:47 PM Tom_L: workin out a few details on the mill project
08:48 PM Tom_L: probably should wait for parts before putting tool to metal though
08:48 PM XXCoder: converting coaxial to rca needs uhf tuner right?
08:48 PM Tom_L: probably
08:48 PM BeachBumPete: did you already order your slides etc/
08:48 PM Tom_L: gonna wait til after the holiday
08:49 PM BeachBumPete: cool
08:49 PM BeachBumPete: they are not cheap huh
08:49 PM Tom_L: i found some that weren't so bad
08:49 PM Tom_L: chinaco of course
08:49 PM BeachBumPete: of course
08:50 PM BeachBumPete: I broke down and ordered my tubing bender finally
08:50 PM BeachBumPete: gotta pick out a die size but I think it will be 1.5" 5" CLR

08:50 PM BeachBumPete: starting to build a stand for the thing and gonna try to mount my cheapo tubing roller to it as well maybe
08:50 PM Tom_L: lookin at that
08:51 PM BeachBumPete: shit thats not bad at all
08:51 PM Tom_L: no, that one ended but i'm sure there are others
08:51 PM Tom_L: may have to cut one axis down a little
08:51 PM Tom_L: i'll see
08:54 PM BeachBumPete: sweet
08:55 PM Tom_L: but any other way they'd be alot more so i think i can cut em if needed
08:55 PM XXCoder: oh VHF tuner has lot more results
09:08 PM BeachBumPete: that should not be too bad
09:08 PM Tom_L: just realized something though
09:08 PM Tom_L: glad i caught it now
09:08 PM Tom_L: the bearing supports aren't the same on each end
