12:37 AM fragalot: hi
12:41 AM fragalot: gregcnc: https://www.youtube.com/watch?v=pjjdgp7yMUA <== this might be a better example of what scraping is and what it should do.
12:43 AM MarcelineVQ: a dehumidifier in a closed space does a pretty good drying job, between the fan and the heat it creates on top of the dehumidifying action
12:45 AM MarcelineVQ: dunno if that's fast enough drying to prevent flash-rust though on particularly prone parts, as long as your air isn't salty I'd expect it to be
12:45 AM fragalot: MarcelineVQ: still prefer not to drag the new-to-me mill through it :P
12:46 AM MarcelineVQ: for sure :>
01:05 AM * fragalot dons a rain coat and goes to sit on a little chair outside to wait for the truck to show up
01:05 AM fragalot: with a tiny flag, of course
01:16 AM MarcelineVQ: and an umbrella from one of those fancy drinks they don't make anymore
01:44 AM fragalot: pfft, heavy storm expected in the next half an hour
01:44 AM fragalot: also, delivery expected approximately then.. based on tracking #, Given that they haven't called yet, again.
01:46 AM MarcelineVQ: how is it being offloaded?
01:46 AM Deejay: moin
01:47 AM fragalot: MarcelineVQ: i'm expecting a pallet jack & lifting door on the truck
01:48 AM fragalot: but it has to travel approximately 200 to 300m to its final destination
01:48 AM fragalot: over gravel
01:48 AM fragalot: ._.
01:48 AM MarcelineVQ: a pallet jack on gravel ;_;
01:49 AM fragalot: i've smoothed it out as much as I can and have boards to put on it
01:49 AM fragalot: but they're rather expensive plywood and the rain is just going to destroy them
01:49 AM fragalot: oh well
01:50 AM MarcelineVQ: I can't recall, was this a schaublin for you?
01:50 AM fragalot: yes
01:50 AM fragalot: Schaublin 13
01:50 AM MarcelineVQ: should be worth the hassle
01:51 AM fragalot: yeah, but it shouldn't have been this much hassle :-)
01:52 AM gloops: where did the schaublin enter the equation fragalot?
01:52 AM gloops: you had a mill and were making a mill, now youve bought another one?
01:52 AM MarcelineVQ: hey now, 3 mills are better than 1
01:53 AM fragalot: gloops: I sold the RF45 after I finished scraping it in
01:53 AM gloops: if youve got 6 arms lol
01:53 AM gloops: oh i see fragalot
01:53 AM fragalot: so I need the schaublin to make the mill I was making
01:53 AM fragalot: obviously.
01:54 AM fragalot: long story short, it's miss0r's fault.
01:54 AM gloops: twists and turns of the machine building saga lol
01:54 AM fragalot: :D
01:54 AM fragalot: this is the most expensive DIY cnc build ever so far, lol
01:55 AM gloops: in for a penny, in for a pound
02:13 AM fragalot: just got a call, delivery estimated in an hour
02:19 AM gloops: hmm, might have found a little bargain - old crappy lathe with shoddy photos, but in the last photo tucked away - baldor speed control and dc motor
04:19 AM selroc: pink_vampire hi
04:19 AM selroc: hello
05:00 AM gloops: ,
05:06 AM Tom_L: morning
05:07 AM XXCoder: yo
05:07 AM XXCoder: 58 air quality here. fresh air(ish)!
05:08 AM Tom_L: 68°F Hi 80
05:13 AM gloops: cloudy and pleasant temps here
05:22 AM jthornton: morning
05:22 AM XXCoder: yo
05:43 AM pink_vampire: hi selroc
05:44 AM XXCoder: yo
05:45 AM pink_vampire: hi XXCoder
05:45 AM XXCoder: hows things
05:48 AM selroc: hi
05:49 AM XXCoder: this is weird http://www.technologystudent.com/cam/cncman5.htm
05:50 AM XXCoder: I just set tool length not make all of em same
05:50 AM XXCoder: also, what about reamers? endmill can be inch out of collet, and reamer tend to be 1000 times longer than that
05:50 AM XXCoder: fine just few inches longer but still much longer
06:03 AM gloops: strange things happen in f360 when switching drawing plane
06:04 AM gloops: first click doesnt present a new plane, but going back and clicking again seems to work
06:05 AM gloops: other quirkiness sometimes, wonder if its down to internet connection
06:28 AM fragalot: hey
06:28 AM XXCoder: hey fragger
06:39 AM jthornton: hey
06:40 AM XXCoder: lol https://www.youtube.com/watch?v=RciHxjtDy0g
06:47 AM gloops: how did it go fragalot?
06:52 AM pink_vampire: XXCoder: LOL
06:56 AM fragalot: gloops: it's in the shed now, but it was damaged during transport
06:56 AM fragalot: some handwheels are bent
06:57 AM gloops: ahh
06:57 AM gloops: no damage to the castings then
06:57 AM fragalot: not that i've seen so far
06:58 AM fragalot: I haven't had the time to look at it in great detail yet as I wanted to get it out of the rain
07:05 AM * fragalot => shed to investigate further
07:05 AM fragalot: definitely needs new belts
07:06 AM gloops: handle shafts will bend back with a bit of tube
07:07 AM fragalot: or my press
07:11 AM gloops: just discovered a minor disaster myself, have run over charger for impact driver...
07:12 AM fragalot: ._.
07:13 AM fragalot: there is a whole box of keys included with this machine yet none fit the cabinet
07:13 AM * fragalot runs back inside to get his picking set
07:20 AM miss0r: fragalot ! status?!
07:30 AM fragalot: open!
07:30 AM fragalot: miss0r: inspection stage. some transport damage.
07:30 AM fragalot: but it is indoors, not yet in place, as I need full access for a while
07:31 AM miss0r: transport damage? did they have it on its side?
07:33 AM fragalot: pallet collapsed
07:33 AM fragalot: hang on photos should have uploaded to cloud by now
07:34 AM fragalot: electrical panel is a work of art
07:34 AM fragalot: https://photos.app.goo.gl/tPyhsNRR9UaMYuJQ6
07:37 AM miss0r: Damn. that is a nice size for your shop.
07:37 AM fragalot: :)
07:37 AM miss0r: But had it been 5cm wider, you would not have been able to drag it down that path of yours :D
07:38 AM fragalot: lol nope
07:38 AM fragalot: we had to remove a fence post for it to clear
07:38 AM miss0r: haha
07:38 AM miss0r: Probally needs a new belt, yeah :D
07:38 AM fragalot: it's the belt for the feed
07:38 AM fragalot: the main one looks fine
07:38 AM miss0r: then just leave it there :P
07:39 AM fragalot: ha. no.
07:39 AM miss0r: why is there no photos of the electrical box? I want to see 'the work of art'
07:39 AM fragalot: loooking for a funnel to feed this thing some oil
07:40 AM fragalot: hang on
07:40 AM miss0r: also, what is the bend stuff?
07:42 AM fragalot: added
07:42 AM fragalot: Z handwheel is bent
07:42 AM fragalot: X handles are bent and broken
07:42 AM fragalot: Z handle is gone
07:42 AM miss0r: uhoh
07:43 AM miss0r: That box looks quite alright :)
07:43 AM miss0r: Atleast its not one of those 'works of art' where the wires are traced on the back of the mounting plate to make it look clean.. quite a nightbare to troubleshoote
07:44 AM miss0r: so. Who is gonna play for those damaged?
07:44 AM fragalot: :P
07:44 AM miss0r: damages*
07:44 AM fragalot: I mailed the seller
07:44 AM miss0r: Perhaps this is why it was so long on the way... They tipped it over and had no idea how to get it back up
07:45 AM fragalot: who knows
07:45 AM miss0r: but damn, that is a cute mill :]
07:45 AM miss0r: I was afraid it would look big once you got it in the shop. But that seems quite alright
07:46 AM fragalot: yeah it is a nice size for here
07:46 AM fragalot: just about on the edge of "too big"
07:46 AM miss0r: One thing I do find worriesom...
07:46 AM fragalot: machine was insured according to seller, so we'll see if DPD honours this
07:47 AM miss0r: that z-wheel, with the bend in it.. that is alot of force to make that shaft bend there... I hope nothing happened to the bearing support arm
07:47 AM miss0r: and how would one calculate what that is worth? :S
07:48 AM fragalot: you'll give me a quote for repairs? :P
07:48 AM miss0r: hurr hurr... :D
07:49 AM miss0r: hehe. I think it will cost more than the machine to have me drive down there and do it. But sure :]
07:50 AM miss0r: I'm all for sticking it to schenker after this treatment you had
07:52 AM fragalot: agreed
07:52 AM miss0r: Can you even crank the z-wheel?
07:56 AM fragalot: yes
07:57 AM fragalot: but it won't disengage
07:57 AM fragalot: it FEELS smooth still, so I think it's just the handwheel portion
07:57 AM miss0r: bah.. That figures.
07:57 AM miss0r: More than likely both ends of the fork clutch
07:57 AM fragalot: I don't want to crank it too much as i'm still putting oil in
07:57 AM fragalot: likely
07:57 AM * fragalot continues to add oil at 1ml/min
07:57 AM miss0r: It must have been on the side
07:57 AM miss0r: the pallet collapsed and the mill went tits up
07:59 AM miss0r: I had a machine today that did not work like it was supposed... I found the smoking gun :D https://imgur.com/a/EZQVsVA
08:00 AM miss0r: Apparently those axle clutches works better of they still have their rubber compound in'em
08:00 AM miss0r: Who would've known
08:01 AM fragalot: lol
08:02 AM fragalot: do these schaublin oil pumps need priming?
08:03 AM miss0r: yes
08:03 AM miss0r: You keep a rubber cone around to put on your air gun?
08:05 AM fragalot: no
08:05 AM fragalot: also, if I pump it, it seems to pull a vacuum on the outlet side
08:07 AM fragalot: priming worked
08:08 AM miss0r: It usualy does :]
08:08 AM FinboySlick: fragalot: Did it just arrive?
08:09 AM fragalot: yes
08:09 AM FinboySlick: You must be giddy as a teen girl at a Beiber concert!
08:09 AM fragalot: :)
08:09 AM FinboySlick: Those are self-priming though.
08:10 AM miss0r: haha
08:18 AM fragalot: Y axis lubrication works!
08:18 AM * fragalot keeps pumping
08:23 AM fragalot: hm
08:23 AM * fragalot needs a large 5phase plug
08:24 AM fragalot: off to the shops
08:24 AM gregcnc: or 3/n/pe?
08:25 AM fragalot: yes
08:26 AM fragalot: bbl
08:43 AM jdh: anyone ever used any cheapish accelerometer demo boards? or know if they will work during a short EMF blast?
08:53 AM FinboySlick: jdh: Are you working on another nuclear warhead *again*?
08:53 AM Simonious: None of your business mom, geez, stay out of my business.
08:54 AM FinboySlick: Damn, now I'm reminded of the nuclear boyscout story all over again.
09:11 AM HexaCube: hey folks
09:11 AM Simonious: o/
09:12 AM HexaCube: Oh man, what a wasted day.... spent all day trying to square up a plate at work, which will be the x-carriage (i'm thinking it should the two large surfaces should be as parallel as possible because that's what will be the reference to the Z-axis rails
09:12 AM HexaCube: no matter how hard I tried to do it properly, the plate had 0.2mm deviation from left to right
09:13 AM jdh: FinboySlick: not this time. 10kA resistance weld occuring nearby.
09:13 AM HexaCube: at the end of the day I though "why not measure if the vice is flat on the table" and see: the vice showed the same deviation...
09:13 AM HexaCube: coworker probably got some chip under it
09:13 AM HexaCube: at least I'm hoping that is the case, idk if it can happen that the entire table is tilted?
09:14 AM Simonious: HexaCube: always fun tracing the problem to it's real source hours after the fact.
09:14 AM HexaCube: because I'm thinking that 0.2mm is ALOT for something that's supposed to be parallel hehe
09:15 AM HexaCube: although I have to think about how I will be able to adjust the different rails in the end to make sure everything is *really* square
09:15 AM HexaCube: is there a common way to do that?
09:16 AM HexaCube: can you shim the rails?
09:18 AM FinboySlick: HexaCube: If you have a very good setup, you could copper-shim them, setup metalic epoxy underneath, tighten the bolts (squishing the shims) to perfection and let it set. It's pretty difficult to do right though.
09:18 AM FinboySlick: Because you're racing the epoxy and you really don't want to have to start over.
09:19 AM HexaCube: (also I'm seeing that this shim tape is really expensive so nevermind that :P)
09:21 AM FinboySlick: HexaCube: Stefan has a video on how he used that technique to set his mill column, let me dig it out.
09:22 AM HexaCube: especially because I'm using aluminum extrusions for parts of the frame, I'm afraid I won't be able to get every surface all square
09:22 AM HexaCube: so, chances are the rails won't be, either. so I'd need some way to make fine adjustments to them, yes?
09:22 AM FinboySlick: HexaCube: https://www.youtube.com/watch?v=U7Qs-J2swIc
09:26 AM FinboySlick: HexaCube: Though yeah, you have to make sure at least some of your geometry is good before you go for something like this.
09:27 AM HexaCube: i mean, at work we *should* have good machines, but... well, I'll investigate tomorrow
09:27 AM FinboySlick: HexaCube: And unless your aluminium is very beefy, a lot of that effort might be lost on flex.
09:27 AM fragalot: back
09:27 AM fragalot: miss0r: insurance doesn't want a quote, they want an invoice >.>
09:27 AM FinboySlick: HexaCube: fragalot won't have any flex trouble.
09:27 AM HexaCube: FinboySlick: I'll mainly be doing just light milling (routing) - but I'd love to do it *properly* even if it is a bit of wasted effort :P
09:40 AM fragalot: miss0r: feed rapids don't work.. >.>
09:40 AM HexaCube: FinboySlick: thanks, I'll give that video a look
09:45 AM fragalot: miss0r: because the wire to the switch got crushed :D (Exact same issue This Old Tony had with his)
10:49 AM fragalot_: miss0r|office: shafts are straightened, one hardened bushing appears broken, and the broken handles are removed with the threads intact... looking good so far :)
10:58 AM Loetmichel: fragalot_: that sounds like you had a little "accident"
10:59 AM miss0r|office: fragalot_: So... how will you make an invoice for the repairs you are doing yourself? :)
11:04 AM fragalot_: miss0r|office: That is a good question, but i'm more interested in getting this thing to work :D
11:05 AM fragalot_: all the handles are back on, everything feels good.. just need to get some handles
11:05 AM miss0r|office: I hear'ya
11:05 AM fragalot_: (plus if I had someone else do it that actually knows what they are doing it would exceed the insured cost anyway)
11:07 AM beachbumpete1: Hey guys was wondering if you could help me with a pneumatic fitting identification...
11:07 AM Loetmichel: fragalot_: what happened?
11:07 AM HexaCube: something i meant to ask... what kinda precision can I get to on a mill, btw? as in, flatness
11:07 AM fragalot_: Loetmichel: pallet cracked during shipping & machine must have hit something hard on the side
11:07 AM Loetmichel: HexaCube: that depends on the mill i would say ;)
11:07 AM Loetmichel: what machine, fragalot_?
11:07 AM HexaCube: Loetmichel: this kinda mill? :P http://plugin.fps-service.de/tl_files/fps/redaktion/fotos/neumaschinen/500M/500m_hydro/FPS500-hydro-freigestellt.jpg
11:08 AM fragalot_: HexaCube: depends very much on the mill. Don't expect better than 0.01mm if it has been recently rebuilt.. If it's an "oldie but goodie", 0.05mm? :P
11:08 AM fragalot_: Loetmichel: Schaublin 13
11:08 AM Loetmichel: fragalot_: ouch. much damage?
11:08 AM fragalot_: miss0r|office: just got a tracking email that your biax is delivered.
11:08 AM beachbumpete1: https://i.imgur.com/g2HWIHj.jpg
11:08 AM HexaCube: fragalot_: so something between 0.01 and 0.05, thanks!
11:08 AM miss0r|office: fragalot_: Nice :D
11:08 AM beachbumpete1: This fitting is broken on our machine and I need to source one like it.
11:09 AM HexaCube: i just hope the table isn't tilted *grumble*
11:09 AM Loetmichel: HexaCube: or up to 0,2 if the machine is weak and you do hard surfaces to fast
11:09 AM fragalot_: Loetmichel: https://photos.app.goo.gl/tPyhsNRR9UaMYuJQ6
11:09 AM HexaCube: Loetmichel: 0.2mm is where i am right now, but I realised the vice wasn't flat for whatever reason
11:09 AM HexaCube: didn't have the time to investigate why, I'm hoping it was a chip that got under it
11:10 AM * HexaCube grumbles about coworkers
11:10 AM fragalot_: HexaCube: this is something you learn early on
11:10 AM fragalot_: trust other people but check it yourself anyway
11:11 AM HexaCube: heh yeah. The thing is, no one expects me to do "precision machining" because it's something I will rarely, if ever, have to do after my apprenticeship
11:11 AM HexaCube: it's just something that "should have been taught and that's it", more or less
11:11 AM HexaCube: ie. I was never told how you actually square things, had to look it up on my own
11:12 AM sliptoni` is now known as sliptonic
11:14 AM sliptonic is now known as Sliptonic
11:21 AM gregcnc: beachbumpete1 those look like swivel elbows. to find the right part you have to know the thread and tubing size. any source will work
11:22 AM fragalot_: miss0r|office: I'm amazed at the fit-up of all these parts.. :D
11:22 AM fragalot_: also just measured backlash. Y is quite bad at 0.06mm, Z is 0.03mm, X 0.01mm
11:23 AM fragalot_: all of which are about 5x less than the RF45 xD
11:41 AM beachbumpete1: gregcnc: thank you my friend. It is actually a push to connect type and the fitting on the other end is a snap on type with o-ring
11:49 AM JT-Shop: beachbumpete1: Fastenal has them
11:49 AM JT-Shop: just need to know if metric or imperial thread and tubing size
11:50 AM beachbumpete1: thats just it JT there IS no thread
11:51 AM beachbumpete1: one side is push to connect and the other just snaps over the o-ringed brass nipple
11:52 AM * JT-Shop looks again
11:52 AM JT-Shop: is designed to come apart or just swivel?
11:53 AM JT-Shop: the brass part should have threads
11:55 AM JT-Shop: http://www.parker.com/Online/Product%20Images/Fluid-System-Connectors-Division/zoom_1000x1000/PLP_W369PLP_zm.jpg
11:56 AM gregcnc: yep remove it and figure out the thread
11:56 AM beachbumpete1: I suppose it is possible that the brass fitting inside that block is threaded as you show there...
11:56 AM gregcnc: it is for sure
11:56 AM JT-Shop: I've used a million of them and have hundreds of them on the shelf and I've never seen one without threads
11:58 AM beachbumpete1: well where it is broked it swiveled and there is an oring on the brass bit and it appeared that it just snapped onto that o ring nipple but perhaps it is all one piece with the ability to swivel
11:58 AM JT-Shop: some swivel some don't
11:59 AM beachbumpete1: OK I will head back over to the machine and measure that hose and try to remove the threaded bit to see if I can get it out and get a new one ordered. Thanks for all the suggestions guys you are the best!
11:59 AM JT-Shop: https://www.mcmaster.com/#push-to-connect-fittings/=1eda6xh
12:00 PM JT-Shop: watch out for 1/4 vs 6mm they are very close in size
12:01 PM beachbumpete1: awesome thank you bb later
12:01 PM JT-Shop: k
12:20 PM HexaCube: are ballscrews hardened?
12:20 PM HexaCube: I've seen people grind them, not sure if that's the reason, though
12:21 PM gregcnc: typically case hardened
12:24 PM miss0r: fragalot_: So, is it flat & square? :)
12:24 PM miss0r: and is it sounding alright - the spindle
12:26 PM beachbumpete1: https://i.imgur.com/fIVt8Ll.jpg :)
12:27 PM beachbumpete1: it's a quarter inch OD hose fitting
12:28 PM JT-Shop: beachbumpete1: that is a straight thread O-ring fitting

12:36 PM beachbumpete1: awesome....looks like fastenal is LITERALLY around the corner too. Thanks JT!
12:53 PM HexaCube: *grumble* so it turns out i used the wrong CAD files for the bearing mounts for the ballscrew
12:53 PM HexaCube: thank god I didn't machine anything for that yet :P
01:15 PM gloops: you better get the mounts right - real pain if theyre out
01:17 PM CaptHindsight: fragalot_: the pallet looks like it was made of driftwood planks
01:19 PM CaptHindsight: I wonder what they didn't bump that machine into
01:19 PM CaptHindsight: was the drivers name Moe, Larry or Curly?
01:34 PM miss0r|office: fragalot !
01:34 PM miss0r|office: :]
01:37 PM fragalot: CaptHindsight: hehe
01:38 PM fragalot: updating album again
01:38 PM gloops: could have been on the boat, bloke told me about a lathe that got loose in the hold once, in heavy seas
01:38 PM gloops: terrifying ordeal for the crew
01:38 PM fragalot: ouch
01:43 PM miss0r|office: fragalot: how does the spindle sound?
01:43 PM fragalot: good
01:43 PM fragalot: feels good too
01:43 PM fragalot: have not tried the other ones
01:43 PM miss0r|office: I'm relieved to hear that. All those bend handles gave me a fuzzy feeling
01:45 PM CaptHindsight: any machine that I ship goes out in a crate
01:45 PM fragalot: same
01:45 PM CaptHindsight: or this happens
01:45 PM fragalot: even with a crate this sometimes happens
01:45 PM fragalot: so inside the crate we put as much bracing as possible
01:46 PM CaptHindsight: it's like the forklift drivers can't judge distance
01:46 PM fragalot: and the electrical panel inside the machine gets extra bracing, and the inside gets a PU foam bag to keep the components stable
01:46 PM fragalot: with a shockwatch sticker or 50
01:47 PM CaptHindsight: we put pyramids made of cardboard on top so that they don't stack or we know if they did
01:47 PM fragalot: our machines are too high to stack :P
01:49 PM CaptHindsight: though I did forget to strap a small surface grinder to the sides of a truck once
01:49 PM CaptHindsight: fell over and bent the handles
01:50 PM fragalot: boo.
01:51 PM CaptHindsight: 68F today, welcome relief from the heat and humidity
01:52 PM fragalot: done for today, happy with how well it's cleaning up so far
01:54 PM CaptHindsight: https://www.educateddriver.org/heres-how-much-time-youll-waste-commuting-in-your-lifetime-by-city/ for the USians
01:56 PM * fragalot is in the red bits
01:56 PM fragalot: 60-90min
01:57 PM jthornton: 30 second commute for me

02:15 PM Tom_L: huh?
02:16 PM FinboySlick: there's a 'fan on' button on the controls.
02:18 PM Tom_L: just trying to help a guy get some info on it
02:18 PM FinboySlick: OK. It just made me curious. I can understand it having a cooling fan but I wouldn't expect it to have a user control for it.
02:18 PM Tom_L: aparently the 5D is switch programable.
02:19 PM Tom_L: maybe it's for the user :)
02:19 PM gloops: slightly bored so ive got a photo of an old classic car on some waste ground - gonna photoshop a sign in the window Â£300 and post it on UK barn finds haha
02:20 PM fragalot: FinboySlick: part cooling? :P
02:20 PM gregcnc: operator cooling?
02:21 PM fragalot: supporter to cheer you on?
02:22 PM Tom_L: i guess it's got a butt load of relays in the pannel
02:22 PM Tom_L: part of the control is gone but the guy want's to try and get it working again
02:36 PM gregcnc: that lathe is so old there is literally one valid google return
02:39 PM fragalot: gregcnc: but it's modern
02:53 PM gloops: would deffo have the lathe
02:54 PM gloops: https://www.ebay.com/itm/Mori-Seiki-CNC-Lathe-Turning-Center-SL-2H-Tool-Turret-Assembly-SL2-H/151755205063?
02:54 PM gloops: seiki-hitachi
03:03 PM gloops: hmm different generation, the 5d wasnt cnc
03:04 PM HexaCube: Mori Seiki, isn't that DMG now?
03:04 PM methods_: dmg-mori
03:05 PM HexaCube: ahh, I see
03:05 PM FinboySlick: And I think the G part of dmg is gildermeister
03:05 PM FinboySlick: D is dekel, no?
03:05 PM methods_: dekel maho gildermeister
03:05 PM methods_: i do believe
03:05 PM HexaCube: Deckel* but yes that is it, I think
03:06 PM methods_: https://en.wikipedia.org/wiki/DMG_Mori_Seiki_Co.
03:07 PM FinboySlick: So they all clumped together. I can't imagine that's great for pricing.
03:07 PM gloops: manual for 5aII - but cant see 5d http://industrialmanuals.com/seiki-m-916.php
03:07 PM HexaCube: I mean, I think I shouldn't say this because they're a competitor to the company I work at, but man do they make sexy looking machines :P

03:08 PM Connor: Hey guys.. Anyone know what would cause the knee of a bridge port to squeal when you lower it? It's like it's some harmonic vibration or something.. I can't figure out what's causing it.. It happened when I would lower it with the crank, and it's even worse now that I've added a power feed for it.
03:10 PM FinboySlick: Connor: Is it the screw that makes the noise or the ways themselves?
03:10 PM Connor: I can't tell, it's so damn loud.. and high pitched..
03:11 PM FinboySlick: My guess if it's high-pitched would be the screw.
03:11 PM FinboySlick: (well, nut)
03:12 PM FinboySlick: Connor: Is yours something like this: https://www.amazon.com/Bridgeport-BP-12060170-Z-Axis-Screw/dp/B00KIV554C
03:12 PM andypugh: Is it a ball nut or acme?
03:13 PM Connor: Yea. that's it.
03:13 PM Connor: andypugh: Acme. Manual Mill
03:14 PM andypugh: Have you tried lubricating the nut?
03:14 PM FinboySlick: That and making sure the three bolts aren't loose.
03:15 PM methods_: are the knee gibs adjusted correctly?
03:15 PM andypugh: Ah, well, itâ€™s a well known fact that the bolts need to be loose and you shold never lubricate it :-)
03:15 PM andypugh: (That isnâ€™t at all a fact)
03:16 PM andypugh: Does the knee have oil nipples? Have they been greased? Grease in oil nipples is distressingly common on machine tools.
03:18 PM Connor: It has a one-shot.. no grease.. just oil.. and I've oiled the heck out of it.
03:18 PM Connor: Gibs look to be good.
03:18 PM andypugh: Worth trying experimentally loosening, and maybe tightening.
03:19 PM Connor: Yup. did that too.
03:19 PM Connor: https://www.practicalmachinist.com/vb/bridgeport-and-hardinge-mills-and-lathes/squeaky-knee-117532/
03:19 PM andypugh: Earplugs?
03:19 PM Connor: https://www.hobby-machinist.com/threads/bridgeport-knee-squeal.4731/
03:19 PM Connor: Other people complaining about the same thing..
03:21 PM gloops: maybe some swarf trapped
03:21 PM Connor: anything is possible.. it's a used machine.
03:22 PM FinboySlick: "I used to be an adventurer like you, but then I took a squeak in the knee."
03:22 PM * FinboySlick memes Connor.
03:35 PM FinboySlick: fragalot's Schaublin doesn't have a squeaky knee. It's a total boss.
03:36 PM * FinboySlick forms a fanclub.
03:36 PM fragalot: :P
03:37 PM FinboySlick: fragalot: Wait, you run gentoo?
03:37 PM fragalot: used to
03:38 PM HexaCube: oh, I have a question. Today I was using an endmill to mill the sides of a piece of aluminum. The sides were *really* rough and it seems there were "flakes" of alu stuck to it
03:38 PM FinboySlick: Come on, it's like herpes, you keep that shit for life.
03:38 PM FinboySlick: ;)
03:38 PM HexaCube: what is the reason for that, too high feedrate? too little rpm? ;_;
03:38 PM HexaCube: (as you can tell, I don't have much machining experience yet)
03:38 PM fragalot: HexaCube: was it by chance a coated endmill, and were you running it dry?
03:38 PM fragalot: because aluminium likes to stick to a lot of coatings
03:39 PM FinboySlick: HexaCube: That and re-cut chips tend to weld in place. Make sure you clear them.
03:40 PM HexaCube: FinboySlick: nooo, I think it wasn't coated. but indeed, no cooling
03:40 PM fragalot: WD40 works well
03:41 PM fragalot: and you want the chips to either fly away, or use an air nozzle to blow them away.. or a brush
03:41 PM FinboySlick: Well, the cooling part isn't what's most important, it's the clearing chips away part that matters. Blasting air helps a lot.
03:41 PM MarcelineVQ: speedspeedspeed, throw the chips farther get ahead of the heat, fastfastfast
03:41 PM HexaCube: but it was honestly just one pass, it didn't really seem like the chips didn't clear (I believe, I didn't really pay attention to it)
03:42 PM HexaCube: rather light cut too, i think... (0.5mm off the side of a 10mm thick plate)
03:43 PM HexaCube: cutting with TC inserts is much more fun :P
03:43 PM fragalot: probably chips welding back on, and i'd guess you were moving quite slow
03:43 PM FinboySlick: Alu is soft which makes it deceptive. you'd think that makes it easier to machine but it actually makes it harder.
03:43 PM HexaCube: I was moving at uhhh... a bit less than 100mm/min I believe
03:43 PM MarcelineVQ: waytooslow
03:43 PM HexaCube: 19mm endmill diameter
03:44 PM HexaCube: hm hmmm, I see!
03:44 PM MarcelineVQ: you should check out a calc to see what speed makes sense for your flute count and spindle rpm, but that's really slow for pretty much any setup
03:46 PM XXCoder: isnt ideal chipload for alum around .001" right?
03:46 PM HexaCube: iirc the formula was 0.03*cutting edges*rpm
03:46 PM XXCoder: chip size
03:46 PM HexaCube: 0.03mm per... tooth? i dunno what that one stands for
03:46 PM HexaCube: to be fair I don't know the speed we're supposed to cut alu, but it's 25m/min for steel
03:46 PM XXCoder: we really need gthx here lol
03:46 PM HexaCube: is it m/min? i should look that up heh
03:47 PM HexaCube: i think it is m/min
03:47 PM gloops: https://www.cutter-shop.com/information/speed-and-feeds-calculator.html
03:47 PM HexaCube: but got it, cutting faster, will do! :P
03:47 PM FinboySlick: Well, if you end up at 100m/min instead of 100mm/min, you're probably still wrong ;)
03:47 PM gloops: thats what i was saying about 50k spindle
03:48 PM HexaCube: "this website cannot be reached" gloops =(
03:48 PM gloops: hmm, dunno why nobody can click my links
03:48 PM MarcelineVQ: works for me gloops, though it assumes min spindle of 10k rpm
03:48 PM fragalot: works for me too
03:49 PM HexaCube: huh now it works for me aswell
03:49 PM FinboySlick: I can click your links, gloops.
03:49 PM fragalot: except the iframe it uses has it's certificate expired
03:49 PM gloops: well there are lots of those calculators online
03:49 PM fragalot: so i'm guessing HexaCube uses android?
03:49 PM HexaCube: nope
03:49 PM HexaCube: Windows and Opera
03:49 PM HexaCube: when clicking the button it says "can't be reached" again
03:49 PM fragalot: perhaps opera is very strict too
03:49 PM HexaCube: it's just the widget, not the entire site
03:49 PM fragalot: yeah their security cert expired
03:50 PM HexaCube: i think I was at 1250rpm
03:50 PM HexaCube: for a 19mm cutter
03:50 PM HexaCube: endmill, I mean
03:50 PM MarcelineVQ: sounds like you're set up for steel
03:51 PM HexaCube: so that's 0.03*3 cutting edges (can you call that teeth?) * 1250rpm = 112.5m/min
03:51 PM HexaCube: feedrate
03:51 PM HexaCube: MarcelineVQ: well that's 50m/min cutting speed
03:51 PM HexaCube: I'm not sure what you'd normally use; I'll look that up in my booklet tomorrow
03:52 PM fragalot: MarcelineVQ: 1250 RPM @ 19mm is 75m/min cutting speed
03:52 PM fragalot: not 50
03:52 PM HexaCube: derp. yes, I actually chose a higher sped, I'm sorry!
03:53 PM HexaCube: I kinda freeballed the RPM then, I thought I calculated it
03:53 PM HexaCube: shame on me
03:53 PM Deejay: gn8
03:53 PM cradek: http://nickhacko.blogspot.com/2018/08/the-cutting-edge-of-manufacturing.html
03:54 PM MarcelineVQ: tryin to find a vid syyl_ did on this
03:55 PM skunkworks: andypugh: https://www.youtube.com/watch?v=Xae2tgTZAzE&feature=youtu.be
03:55 PM HexaCube: MarcelineVQ: no need to, I'll be heading to bed ina few minutes
03:55 PM fragalot: the only recommendation I have regarding speeds & feeds
03:55 PM skunkworks: http://electronicsam.com/images/greenmachine/20180820_151647.jpg
03:55 PM fragalot: is to just consult the manufacturer spec to see what they recommend as a starting point for your material
03:55 PM fragalot: failing that, there's the engineers bible
03:56 PM HexaCube: yup, I was too lazy today to check the "bible" :P
03:56 PM HexaCube: but I was curious about the reason for the weird surface
03:56 PM fragalot: the reason is chip welding
03:56 PM fragalot: skunkworks: looks like it worked alright :D
03:57 PM HexaCube: alright... man I really hope I can get the plate square tomorrow
03:58 PM HexaCube: doesn't even have to be square, just has to be parallel :P
03:58 PM fragalot: I'm off - gnite all
03:59 PM MarcelineVQ: wonder why I can't find this vid, he did one on endmill feed calcs
03:59 PM MarcelineVQ: oh hmm https://www.youtube.com/watch?v=MOEkoSvA30A
04:00 PM FinboySlick: HexaCube: Well, worse comes to worse... If its thickness reaches zero, you can consider all its sides parallel.
04:00 PM MarcelineVQ: sidenote: If you patent the method you used to hold the material you just cut to 0 you could be a rich man
04:01 PM FinboySlick: MarcelineVQ: Nah. 0mm thick material is infinitely abundant and free.
04:02 PM HexaCube: FinboySlick: eh I still have 1.5mm or so to screw up :P
04:03 PM FinboySlick: Well, I've said enough useless nonsense for one day. Good luck HexaCube and bye everyone.
04:03 PM HexaCube: thanks, I'll need it
04:03 PM HexaCube: o/
04:04 PM MarcelineVQ: put that vid on your backlog of things to watch HexaCube it's a little more than just the calcs and I recall it being pretty informative in general
04:04 PM HexaCube: added to 'Watch Later'
04:04 PM HexaCube: thanks for looking it up for me
04:07 PM HexaCube: I wish I was good at welding....I could just weld everything together instead of figuring out how to screw it all
04:07 PM MarcelineVQ: I'm not sure if he covers speed but he covers calcualting rpm at least, so you can tell prety quickly that if the rpm you're getting is too high your speed is too low. at the very least you'll end up with a list of terms you can learn more about, chip load, sfm, rpm, etc
04:27 PM andypugh: skunkworks: I like that. A different Sam, or you?
04:27 PM skunkworks: dad
04:55 PM Tom_L: cradek if i had a ceramic cutter like that i think i'd just sit and look at it a whiel
04:58 PM infornography: is there an "NEW ENCO" that all the cool kids buy tools at after ENCO went away?
04:59 PM infornography: I liked ENCO :(
05:02 PM _unreal_: https://www.youtube.com/channel/UCtrf6ZiE6hw3k77hGpnuQWg
05:13 PM infornography: Can't get giant paper catalogs anymore either, I miss giant catalogs
05:13 PM _unreal_: infornography, to what?
05:15 PM skunkworks: infornography: maybe try zoro on ebay?
05:15 PM infornography: Industrial supply and electronics catalogs.
05:16 PM infornography: I used to have ENCO and MSC and Mouser catalogs.... I'm just being nostalgiay I guess
05:17 PM infornography: I have been ebaying stuff lately
05:18 PM infornography: It's pretty darn convenient
05:24 PM andypugh: Mouser sent me a giant paper catalogue only a couple of years ago.
05:24 PM andypugh: <checks> Well, 2011.
05:24 PM andypugh: I donâ€™t think I ever opened it.
05:25 PM skunkworks: I have 2 mousers as monitor risers..
05:25 PM infornography: see how useful!
05:26 PM skunkworks: I wouldn't want to thumb through a catalogue - when you can go to their site and use the search matrix
05:26 PM SpeedEvil: it can be useful.
05:26 PM SpeedEvil: 'what the fuck is this connector'
05:27 PM SpeedEvil: Someone needs to do OCR on that.
05:29 PM skunkworks: that is what google is for. ;)
05:31 PM infornography: I liked thumbing through them to pick out things that I didn't know I needed
05:34 PM skunkworks: my dad is very good at picking up a book - thumbing throug it for 2 seconds and finding the page he needs. It is magic
05:35 PM Tom_L: he's been thru it before
05:35 PM Tom_L: :)
08:26 PM _unreal_: should I go with lubuntu or xubuntu? on my tinkherboard?
08:26 PM _unreal_: tinker
08:28 PM Tom_L: use the one that works
08:29 PM _unreal_: and I would know that how?
08:29 PM Tom_L: trying them both
08:30 PM Tom_L: you are likely covering uncharted territory with it
09:01 PM Tom_itx: _unreal_, https://tinkerboarding.co.uk/forum/thread-69.html
09:08 PM _unreal_: http://www.elar-systems.com/website/index.php/entertainment/member-area/category/2-downloads
09:10 PM _unreal_: Tom_itx, I dont know which is more mature
09:10 PM Tom_itx: don't you want one with RTOS?
09:10 PM _unreal_: I cant do anything sence I dont seem to have a DAMN SD card currently
09:10 PM Tom_itx: err RTAI
09:10 PM _unreal_: fuck it tomorrow I'm going to buy YET an other one
09:10 PM _unreal_: rtai?
09:12 PM Tom_itx: realtime application interface
09:12 PM Tom_itx: lcnc uses RTAI or preempt-rt
09:12 PM CaptHindsight: preempt_rt
09:12 PM CaptHindsight: look over the forums and see which distro has less bugs
09:12 PM Tom_itx: depending on the app
09:12 PM CaptHindsight: I'm sure it's as buggy as hell
09:14 PM _unreal_: sigh
09:14 PM CaptHindsight: the devs goals seem to be get it to boot, never clean anything up
09:14 PM CaptHindsight: I hope I'm wrong
09:15 PM CaptHindsight: https://tinkerboarding.co.uk/forum/forum-4.html
09:18 PM _unreal_: whish I knew why I'm so @#$@# tired
09:18 PM _unreal_: I'm head bobbing and its 10pm
09:18 PM _unreal_: wtf
10:12 PM CaptHindsight: _unreal_: is it hot and humidity, high CO level, are you ill?
11:46 PM fragalot: morning
