12:45 AM miss0r: mornin
12:50 AM pink_vampire: hi miss0r
12:52 AM miss0r: are you up to anything interresting, pink?
12:52 AM pink_vampire: need to make 3 pvc parts
12:58 AM miss0r: doesn't sound too crazy ;)
12:58 AM pink_vampire: I'm thinking to make one of them with the sine plate
12:58 AM miss0r: sweet. do you have some drawings I can look at?
01:24 AM pink_vampire: miss0r: https://i.imgur.com/KiFNJF0.png
01:24 AM miss0r: that is a pretty interresting looking part. Might I ask what it is for?
01:25 AM pink_vampire: sure
01:25 AM pink_vampire: it is actually 3 parts that going to be glue together,
01:26 AM miss0r: are you going to be glueing the flats with the holes together?
01:28 AM pink_vampire: https://i.imgur.com/KhuBwSS.png
01:28 AM miss0r: ahh, so the part is made up of three seprate parts
01:28 AM miss0r: Why not make it as one?
01:29 AM pink_vampire: i have the pvc in sheets, and it is very easy to glue
01:29 AM pink_vampire: this is just a fancy holder to the servo driver
01:30 AM miss0r: true. if acuracy is not of the essence :)
01:30 AM miss0r: My job for today is not nearly as intertaining.
01:31 AM miss0r: At the moment I am waiting for some relays to get here via mail. Then I have to replace the innerts of some emergency stop redundand relay controller...
01:31 AM miss0r: alot of soldering today
01:35 AM pink_vampire: one sec I'm on the phone
01:43 AM miss0r: write my name when you are back ;)
01:44 AM miss0r: CaptHindsight: yes. and shrinkwrap
01:45 AM miss0r: (the ones with glue inside of'em) :)
01:46 AM CaptHindsight: https://www.3m.com/3M/en_US/company-us/all-3m-products/~/All-3M-Products/Energy/Electrical-Construction-and-Maintenance/Wire-Cable/Insulation/Heat-Shrink-Tubing/?N=5002385+8709319+8710679+8710817+8711017+8730567+8743879+3291756777+3294857497&rt=r3
01:51 AM miss0r: something like that
02:17 AM Deejay: moin
04:14 AM jthornton: morning
04:23 AM XXCoder: mornin
04:34 AM jthornton: you gotta love programmers documentation lol
04:34 AM jthornton: Set/Get the position of the camera in world coordinates.
04:34 AM jthornton: The default position is (0,0,1).
04:34 AM jthornton: wtf does (0,0,1) mean lol
04:34 AM jthornton: https://vtk.org/doc/nightly/html/classvtkCamera.html#a6735b97c80941b8fd118b94ac207a921
04:35 AM XXCoder: x0 y0 z1
04:36 AM XXCoder: i dunno why its not 0 0 0 tho lol
04:36 AM jthornton: you would think they would spell that out lol
04:37 AM Loetmichel: XXCoder: probab,y because you would have the ground plane splitting your picture in half then ?
04:38 AM XXCoder: hmm guess thats true
04:38 AM XXCoder: depends on setup
04:39 AM jthornton: vtk has almost zero information about it
04:40 AM XXCoder: setviewUP? up? weird
04:41 AM jthornton: yea I think that rotates the object to set the up side
04:43 AM XXCoder: many of those functions is pretty olvious just odd in some cases
04:43 AM jthornton: wow I have 0.3GB of data per day for the rest of the month lol
04:44 AM XXCoder: thats fun
04:45 AM jthornton: I installed a module in my new store and it broke the store... going to take two days to delete the online files and upload again lol
04:46 AM XXCoder: bleh
04:46 AM XXCoder: my phone I only use .5 gb a month approx
04:51 AM miss0r: so, should any of you ever find yourself in a picle & realy realy needing to replace the relay board of a siemens 3TK2608 redundand safety relay, let me know :)
04:52 AM miss0r: I have just spend the morning reverse engineering it, designing the PCB and am currently isolation milling the first one
04:52 AM XXCoder: nice though dont need one lol
04:53 AM miss0r: yeah.. hehe
04:54 AM miss0r: They have gone out of production. and they are SO expensive, I can do this and the client still comes out on top
04:54 AM Loetmichel: siemens. what did you expect?
04:54 AM miss0r: Loetmichel: Exactly that
04:54 AM miss0r: :)
04:55 AM Loetmichel: like a supplier once said: "BRauchste was gescheits oder darfs auch von siemens sein?"
04:55 AM Loetmichel: (do you need something proper or will siemens parts do?"
04:55 AM Loetmichel: )
04:57 AM miss0r: lol
05:00 AM miss0r: I might not have thought this one through...
05:00 AM miss0r: I can't seem to find support for ellipse throughhole milling in coppercam
05:01 AM jthornton: opps
05:02 AM Tom_L: morning
05:06 AM miss0r: ffs! I just broke the tip of the routing tool
05:08 AM jthornton: morning
05:08 AM miss0r: mornin indeed
05:09 AM Loetmichel: miss0r: thats why you order the V-bits in 10-packs ;)
05:09 AM miss0r: I hope that thing was just worn... and that theres nothing wrong with the tool path :] I will go get some lunch & when I come back I hope to find a finished part and not another broken tip
05:10 AM miss0r: Loetmichel: Sure.. but this is a much nicer tool i'm using.
05:10 AM miss0r: 60degree v-bit with spital flutes
05:10 AM miss0r: leaves a realy pretty finish. but it is rather expensive :D
05:10 AM miss0r: anywho bbiab
05:11 AM Tom_L: 18°F Hi 26
05:12 AM Loetmichel: miss0r: i use those with 30°: https://www.sorotec.de/shop/Zerspanungswerkzeuge/sorotec-werkzeuge/Gravurwerkzeuge/Gravierfraeser/
05:12 AM Loetmichel: not cheap but well worth the price
05:15 AM Tom_L: revisited my thread macro last night and added user selectable multi passes
05:16 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro_multipass2.jpg
05:16 AM Tom_L: noticed on some coarse threads 2 might not be enough
05:18 AM Tom_L: Loetmichel better than a halfround bit?
05:20 AM Loetmichel: Tom_L: you mean a "D-bit"?
05:20 AM Tom_L: yeah same thing :)
05:20 AM Loetmichel: WAY better. especially in metal
05:20 AM Loetmichel: it has the right cutting angle for alu and brass
05:21 AM Loetmichel: unlike the D-bits which have the inner angle at 0°
05:21 AM Tom_L: right
05:22 AM Tom_L: hah china's idea of it: https://www.ebay.com/itm/5Pcs-3mm-30-deg-0-1mm-Tungsten-Carbide-Two-Double-Flutes-Spiral-Engraving-Bit/142710168912?hash=item213a305d50:g:7tcAAOSwHnFV0wog:rk:1:pf:1&frcectupt=true
05:24 AM Loetmichel: MUHAHAHA
05:25 AM XXCoder: wtf
05:26 AM XXCoder: is it drill? is it endmill? is it engraver sharp bit? how about ALL!
05:26 AM Tom_L: reground broken drillbits :D
05:27 AM Loetmichel: looks like it, yes
05:27 AM XXCoder: yeah
05:27 AM XXCoder: kinda good idea, because why not.
05:27 AM XXCoder: but price bit high for just regrund tool
05:43 AM miss0r: Loetmichel: I use something that looks like it. only my carbide has a Ti coating on the end
05:53 AM Loetmichel: XXCoder: i do that all the time with broken TC mill bits... freehand. i wouldnt sell them though: https://www.youtube.com/watch?v=4iaFb6WInuw
05:53 AM miss0r: ffs. This project is not going my way
05:54 AM miss0r: It seems I am out of 0.8mm carbide endmills
05:54 AM miss0r: I have 50+ 0.5 and 50+ 1.0
05:54 AM miss0r: and alot of the even smaller ones that I never use
05:54 AM miss0r: damnit :D
05:54 AM XXCoder: is it radius sensive?
05:54 AM XXCoder: ie: makes features that depend on radus
05:54 AM miss0r: yeah
05:55 AM XXCoder: too bad. oh well
05:55 AM miss0r: It seems that is the only way I can do the ellipse slots in the coppercam software
05:56 AM miss0r: I suppose I can cheat it to use a 0.5... but using a 0.8 would allow me to do it ALOT faster :)
05:57 AM miss0r: also, they are not as prone to breaking
05:57 AM XXCoder: yeah
05:57 AM Loetmichel: indeed. the smalles 2 flute i use regularily is 0.6mm
05:58 AM Loetmichel: the 0.4mm i have you cant even sneeze near the machine when they are cutting without them breaking ;)
05:58 AM miss0r: I found one!
05:59 AM miss0r: but its a stubby bastard... I think I will get a slightly tapered hole pushing it through a 1.5mm PCB
05:59 AM miss0r: Apparently I have a few, actualy - I just had to look in the chinesium drawer
06:10 AM pink_vampire: i just use an end mill for pcb
06:11 AM Loetmichel: pink_vampire: works if you have pretty coarse PCBS.
06:12 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17301&g2_imageViewsIndex=1 <- 0.8mm end mill
06:12 AM pink_vampire: 1/32" (0.8mm)
06:13 AM pink_vampire: yeah similar to the stuff i do
06:13 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14498&g2_imageViewsIndex=1 <- 0.1mm 30° V-bit
06:13 AM pink_vampire: can't see anything
06:14 AM Loetmichel: https://www.youtube.com/watch?v=b6NQ-05A0qc <- video
06:14 AM Loetmichel: with a 30° v-bit
06:14 AM Loetmichel: and 1mm FFC connectors adapter
06:14 AM pink_vampire: pshhhhhhhhhhhhhhh
06:15 AM XXCoder: I wonder how fine a engraver can be done lol
06:15 AM Loetmichel: XXCoder: depends on machine
06:15 AM XXCoder: yeah though there must be a lower bound?
06:15 AM Loetmichel: i am hard pressed to do 0.1mm wide insulation channels. 0.2mm works fine
06:15 AM Loetmichel: 0.3mm and you can use F2000 ;)
06:16 AM Loetmichel: (mm/min)
06:16 AM XXCoder: interesting
06:16 AM Loetmichel: https://www.youtube.com/watch?v=jMXxjT4nNxg 0.2mm wide insulation channel, F1200 ;)
06:16 AM miss0r: oh gawd!
06:16 AM miss0r: ffs :-/
06:17 AM miss0r: Instructions: linear motion with a 0.8mm endmill to make a 0.8mm slot
06:17 AM miss0r: actual outcome: 1.6mm wide slot because it thinks it needs to clean up the hole or something
06:17 AM Loetmichel: result: http://www.cyrom.org/palbum/main.php?g2_itemId=14507&g2_imageViewsIndex=1
06:17 AM miss0r: now the whole soldering island is gone
06:18 AM XXCoder: Loetmichel: nice video!
06:27 AM miss0r: Why the hell has it decided that my slots are so wide!?!
06:28 AM pink_vampire: miss0r: where?
06:28 AM pink_vampire: miss0r: where?
06:28 AM miss0r: doing a pcb at the moment. and I just wrecked it...
06:28 AM miss0r: I have some relays I need to solder on there, which has spade connectors. I needs slots for those
06:29 AM pink_vampire: what do you mean?
06:29 AM miss0r: and the cam software has decided to completely ignore the size I have set and made up its own
06:29 AM miss0r: and it seems theres nothing I can do to change its mind
06:29 AM miss0r: :-S
06:30 AM XXCoder: wb
06:30 AM pink_vampire: ?
06:31 AM pink_vampire: my irc got disconnected
06:35 AM XXCoder: miss0r: weird allright. sometimes wish theres better previews
06:35 AM XXCoder: like vr milling lol realistic looking so you can actually see how it looks like.
06:35 AM XXCoder: with imports of object you plan to mill
06:35 AM miss0r: well... it 'does' show the slotted through hole as an oversize.. but I didn't notice it
06:36 AM miss0r: and I am apparently unabled to change it at the moment :S
06:43 AM miss0r: Some of the more expensive cam/cad packages has that
06:43 AM miss0r: This is not expensive...
06:44 AM miss0r: I don't recall how much it was (Oh my god yes, I have actualy payed for something) :)
06:44 AM XXCoder: lol
06:44 AM miss0r: but I pretty much had to get it. It was the only software that could talk directly to my desktop mill
06:45 AM miss0r: 80eur for a lisence .)
06:46 AM XXCoder: not too bad
06:52 AM miss0r: but it is still fucking with me :-(
06:59 AM pink_vampire: https://www.youtube.com/watch?v=hVZ-ABxf5NM
06:59 AM pink_vampire: now i want to get a lock
07:07 AM XXCoder: you can get special power switch that has lock built in it
07:08 AM x2s: Hi. People from Germany, where do you get your milling cutters from? Any suggestions for a shop?
07:08 AM pink_vampire: i have a main switch with option for 3 locks
07:08 AM XXCoder: i heard of one guy who was inside larger cnc mill when operator come in and started machine :(
07:08 AM XXCoder: got very dead. :(
07:10 AM TekniQue: you can also get special tag plates for LOTO operation
07:10 AM TekniQue: that you can attach a bunch of locks to
07:10 AM TekniQue: if you have more than one person in the danger zone
07:11 AM TekniQue: https://www.totallockout.com/online-store/safety-lockout-hasps/
07:11 AM TekniQue: this kind of stuff
07:17 AM miss0r: x2s: what are you milling?
07:18 AM miss0r: well, in either case; have a look at kemmler
07:27 AM x2s: miss0r: wood and aluminium
07:27 AM miss0r: well. kemmler has some good stuff. also, the prices are very reasonable. I live in Denmark, but have a local supplier that sells the kemmler brand. Would be worth looking up - I believe it is german
07:29 AM miss0r: might be a smidge expensive, if you are running a hobby shop. But the right stuff costs a little extra
07:29 AM x2s: miss0r: will have a look. Thank you
07:29 AM miss0r: no problem
07:30 AM x2s: 12-15 EUR is ok
07:30 AM x2s: if it's worth the price and doesn't stays sharp for a long time, it's a good investment
07:31 AM miss0r: revisit that last line :)
07:31 AM miss0r: but, I know what you are getting at :)
07:32 AM x2s: Eh, yes :D
07:34 AM x2s: Kemmler doesn't have cutters with 3mm shaft diameter :/
07:36 AM miss0r: perhaps if you can find a seller of sgs tools
07:36 AM miss0r: sutton tools are also within acceptable
07:37 AM pink_vampire: x2s: i just get stuff from ebay
07:37 AM pink_vampire: about 3$ for end mill
08:50 AM gregcnc: pink_vampire is your mill running again?
08:51 AM pink_vampire: no
08:52 AM pink_vampire: just the high seed spindle
08:52 AM gregcnc: no solution for the supply voltage?
08:52 AM pink_vampire: servo driver
08:54 AM gregcnc: yeah it died, we figured it was due to regen on braking and suggested dumping excess voltage
08:54 AM pink_vampire: I made the return energy dump
08:55 AM pink_vampire: I'm trying to rebuild it now
08:55 AM gregcnc: ah ok
08:55 AM gregcnc: someone was asking about DIY tool setter. i couldn't find links you yours
08:55 AM pink_vampire: also the spindle going to get the old DC controller from the original spindle of the machine
08:57 AM pink_vampire: https://i.imgur.com/d6E1pkb.jpg
11:40 AM fragalot: hi
11:59 AM fragalot: well this is unfortionate
11:59 AM fragalot: this morning in the news: "brand new pool burned down before it opened this saturday"
11:59 AM fragalot: in my mailbox: "grand opening of new pool!"
12:00 PM gloops: so you missed it lol
12:01 PM fragalot: :D
12:01 PM fragalot: it looked fun
12:05 PM MarcelineVQ: local pond found to be mostly kerosene, claims charred man
12:05 PM fragalot: lol
12:06 PM fragalot: https://www.vrt.be/vrtnws/nl/2019/02/26/brand-zwembad-kortrijk/
12:07 PM MarcelineVQ: really though a pool burning down, that's fairly comical
12:20 PM gloops: cheap, not sure i like the single locking nut though https://www.ebay.co.uk/itm/Myford-Milling-slide-7-S7-other/132966234157?
12:23 PM miss0r: 'evening
12:23 PM fragalot: 'ello
01:52 PM gloops: ammendment to block no-deal brexit defeated
01:53 PM gloops: 30 days to go
01:53 PM fragalot: they'll try again on the 13th
01:53 PM fragalot: then fail again, at which point they'll vote for that other thing, which will also fail, putting them back where they started so they can blame may for everything
01:56 PM miss0r: man... This coppercam is realy starting to get on my nerves!
01:56 PM fragalot: the what now?
01:57 PM miss0r: coppercam... Its a PCB milling cam for my roland desktop mill
01:57 PM miss0r: theres just so many things that pisses me off about it at the moment
01:58 PM miss0r: moving around the origin coordinates/changing the board size ect.. it should NOT do these things, yet; it does so whenever I import a new layer
01:58 PM miss0r: and don't get me started on flipping the axis, when doing the other side... God almighty
01:58 PM miss0r: this board should've been a two hour job (design, milling & soldering included). I've been at it for 8 hours now
01:59 PM miss0r: No way I can bill the client all of that :/
01:59 PM miss0r: so.. I need better software :D
01:59 PM fragalot: lol
01:59 PM fragalot: should 've just sent it out to eurocircuits & called it a day
01:59 PM miss0r: yeah
01:59 PM fragalot: unless you need the part RIGHT NOW, it makes zero sense to DIY circuit boards anymore these days
02:00 PM miss0r: well I do with this one
02:00 PM miss0r: but the remaining 5 I will order there
02:00 PM fragalot: etch it then :P
02:01 PM miss0r: nah.. I'm milling the second side of the pcb now. I managed to line it up. but it took waaay too much effort with a calculator and manual offsetting
02:01 PM fragalot: what are you milling it on?
02:01 PM fragalot: please don't say the maho with the super slow spindle :P
02:01 PM miss0r: the roland camm-3
02:01 PM miss0r: hey.. respect the maho! :D
02:02 PM fragalot: :D
02:02 PM fragalot: they still haven't run the deckel at work >.>
02:02 PM miss0r: meh..
02:02 PM miss0r: are you not allowed near it?
02:02 PM fragalot: not part of my job description to mill out the cabinets
02:03 PM miss0r: so, thats a yes?
02:03 PM fragalot: all I did was set the machine up for them ready to use, and went back to my normal tasks
02:03 PM miss0r: throw a wrench in the gearbox, and have them call me to repair it :D
02:03 PM fragalot: i'm allowed near it if I want to, just have more pressing matters to attend to :p
02:03 PM fragalot: haha
02:04 PM miss0r: I think I'll press my luck and try'n engrave my logo on this pcb... what could possibly go wrong? :D
02:04 PM fragalot: go all out and only mill it half the copper depth :P
02:06 PM miss0r: hehe.. I think this setup combining MDF, double sided tape & oddball PCB blanks will make that a real challange :D
02:07 PM miss0r: unless somehow the gods smile upon me, and they all equal out... :o
02:07 PM fragalot: xD
02:07 PM fragalot: depends on the moisture content of the MDF
02:07 PM miss0r: that depends on where you measure... near/far away from the most resent coffee spill...
02:08 PM miss0r: I wonder how/if it is possible to convert a jpeg to vectors in diptrace...
02:08 PM miss0r: nah... I have other software to do that
02:08 PM miss0r: screw coppercam
02:08 PM Jymmm: miss0r: I don't know what diptrace is, but you can in inkscape
02:08 PM fragalot: inkscape ftw for that stuff
02:09 PM miss0r: Jymmm: thanks :) But I have some realy low tech software that can run the cnc direct that can do that as well
02:09 PM miss0r: also, the software I have for that is called dr. engrave and is only 102kb :D
02:09 PM miss0r: so; the bare minimum
02:10 PM gloops: PVA the mdf
02:11 PM fragalot: pva everything.
02:11 PM fragalot: make sure to add the moisture first
02:11 PM fragalot: for best results, replace way lube with pva
02:12 PM miss0r: well.. that escalated quickly..
02:13 PM miss0r: fragalot: Theres alot of ways to do this; but the only relays I could get on a short notice that met the requirements have those nasty flat spade connectors on'em.
02:14 PM miss0r: so I basically needed atleast the through holes to be milled
02:14 PM fragalot: bigger hole & bigger glob'o'solder :D
02:14 PM gloops: tape doesnt stick to mdf well, a lot better when its sealed
02:14 PM miss0r: hehe, I also thought about that to be honnest - but I ran into a design issue... I didn't have enough room to route everything with circular pads
02:15 PM fragalot: depends on the tape, the stuff I use tears the mdf in half if you try to peel it off
02:15 PM miss0r: gloops: If my double sided tape sticks any better to the MDF, I could never get it off
02:15 PM miss0r: does that also line up beautifuly on your screen? :D
02:15 PM fragalot: the end of it does
02:16 PM gloops: which tape is this?
02:16 PM miss0r: for low force applications(like PCB) I use some nitto tape
02:16 PM fragalot: I use the cheap stuff from 'action', a discount shop here.. no idea what brand it is, but that stuff is impossible to release from anything even remotely unpolished
02:17 PM gloops: (i was thinking masking tape + superglue)
02:17 PM fragalot: but it comes off easily using chemicals
02:17 PM miss0r: for high strength, I use the double sided tape that the carpenters use when assembling the moisture resistant plastic sheets around the insulation
02:18 PM miss0r: that stuff does not come off in a hurry
02:18 PM miss0r: i've never found masking tape & superglue to my liking, honnestly
02:18 PM miss0r: I usualy superglue directly :)
02:19 PM gloops: hmm, you can get really sticky double sided stuff like that from upvc window supplies, in varying thickness, from 1mm up
02:20 PM fragalot: you want it to be thin & stiff
02:20 PM fragalot: not thick & spongey
02:20 PM gloops: 1mm is ok
02:22 PM * miss0r is seriously pondering weather or not to add the logo.
02:22 PM miss0r: With the days events leading up to this; theres a 50/50 chance I'll cut 3 leads & two pads in half trying
02:23 PM miss0r: so; I think I'll go ahead and give it a go :D
02:24 PM fragalot: mill yourself a blacksmith's stamp & stamp your logo
02:24 PM fragalot: :D
02:24 PM miss0r: haha
02:24 PM miss0r: yeah :D
02:24 PM fragalot: just whack it on there
02:24 PM miss0r: I think my chances of success is about the same either way
02:25 PM fragalot: if it's a low speed circuit, i'm a bit disappointed you didn't have the traces as your logo
02:25 PM miss0r: next time you can do the design for me.
02:25 PM fragalot: no.
02:25 PM miss0r: b..but.. I insist?
02:26 PM fragalot: ..maybe.
02:46 PM gloops: not a bad profit margin on a £12 sheet of MDF https://www.ebay.co.uk/itm/1-12-scale-Dolls-House-Emlyn-Castle-signed-and-dated-by-DHD/332235851368?
02:50 PM andypugh: Pretty cool though.
02:53 PM gloops: probably quite a bit of fiddly work involved
02:53 PM andypugh: And a lot of original design work.
02:57 PM gloops: i liked this one https://www.ebay.co.uk/itm/163550520708?
02:58 PM gloops: i dont suppose theyre made with old men in mind though heh
02:58 PM CaptHindsight: I'm changing my name to Boomhit
02:59 PM CaptHindsight: or Bhoomit, quite an action name
02:59 PM fragalot: but why
02:59 PM CaptHindsight: uhmericans have boring names
03:06 PM djdelorie: speak for yourself
03:08 PM gloops: Dreadnought
03:12 PM gloops: http://victorian-era.org/victorian-era-name-generator.html
03:15 PM CaptHindsight: Khazaam
03:16 PM CaptHindsight: Shabhoom
03:16 PM CaptHindsight: really makes an entrance
03:16 PM CaptHindsight: but getting near the edge of rappery
03:17 PM djdelorie: that's not a name, that's theme music
03:52 PM Deejay: gn8
05:02 PM Jymmm: Well, new hose seems to be holding 100 PSI so far =)
05:02 PM * Jymmm pokes CaptHindsight for no reason
05:05 PM Tom_L: what's it rated for?
05:06 PM Jymmm: The hose is rated for 300PSI, but the gauge I have on the far end max out at 100 psi
05:07 PM Tom_L: is it bending the needle yet?
05:07 PM Jymmm: I charged the hose to 100, then turned off the nitrogen tank.
05:07 PM Tom_L: if not it's stil 100psi
05:07 PM Jymmm: and just waiting right now
05:07 PM Tom_L: leak test
05:07 PM Tom_L: what's the hose for?
05:07 PM Jymmm: pretty much. propane is what I'm going to use it for
05:08 PM Tom_L: yeah you were looking at fittings a while back..
05:08 PM Jymmm: I found the fittings
05:09 PM Tom_L: dunno what that has to do with surgical tweezers...
05:09 PM Jymmm: https://www.homedepot.com/p/Husky-1-4-in-x-50-ft-Polyurethane-Air-Hose-14-50-HOM/205331829
05:09 PM Jymmm: and the hose is field repairable too =)
05:10 PM Tom_L: i've got a flex hose on my compressor that has no clamps, just a push on fitting
05:11 PM Tom_L: i was a little skeptical when i got it but it's never failed or leaked
05:11 PM Tom_L: ~175psi
05:11 PM Tom_L: just rubber hose pushed on the fitting
05:13 PM Tom_L: that stuff cracks after while
05:14 PM Tom_L: at least the outer
05:15 PM CaptHindsight: ooooouuuuucchhhh
05:15 PM CaptHindsight: sorry over reacted
05:24 PM jthornton: push on hose with the correct fitting will not come apart without a knife
05:25 PM Tom_L: it's been on there for years
05:26 PM jthornton: the weave on the cord is like a chinese finger thing
05:26 PM Tom_L: yeah
05:28 PM Tom_L: did you see the latest rev of the thread macro?
05:28 PM Tom_L: user selectable number of passes
05:29 PM Tom_L: hard to say where it'll go next
05:29 PM jthornton: lol, no I've not seen it... sounds like chicken coop programming there is no end lol
05:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro_multipass2.jpg
05:30 PM Tom_L: inside & outside
05:30 PM jthornton: cool
05:30 PM Tom_L: lead in changes depending on which one you pick
05:30 PM Tom_L: center for the inside, outside for the other one
05:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/ThreadMill_Multi.mcl
05:32 PM Tom_L: major, minor diameters then it divides them equally
05:32 PM jthornton: looks pretty straight forward programming
05:32 PM Tom_L: it is. kinda limited in some ways
05:33 PM Tom_L: no for next loop
05:33 PM Tom_L: gotta use while
05:34 PM Tom_L: the whole thing is alot easier to edit compared to a fusion360 post or such
05:48 PM tiwake: CaptHindsight: hey, I just got back from that houstex convention
05:48 PM CaptHindsight: nice time?
05:48 PM tiwake: I was vibrating the entire time... lol... I love machines so much
05:48 PM tiwake: last night I slept for 10-11 hours
05:49 PM tiwake: (was at the show yesterday)
05:49 PM tiwake: they had some 3D printers, but no SLS type
05:49 PM CaptHindsight: big shows can be fun
05:51 PM tiwake: they had one there where it was a plastic+metal thing and the plastic gets baked out
05:52 PM tiwake: I didn't like it though
05:53 PM tiwake: gotta buy special crap
05:58 PM CaptHindsight: they make most of their money on the special crap
05:58 PM tiwake: yeah
05:58 PM tiwake: I don't want special crap, I just want SLS... heh
05:59 PM CaptHindsight: the closed designs all use the inkjet model
05:59 PM CaptHindsight: lock in
05:59 PM tiwake: CaptHindsight: for SLS, does there have to be support structures? or is the surrounding powder good enough support?
06:00 PM CaptHindsight: there seems to be price fixing for plastic SLS powders
06:00 PM CaptHindsight: the surrounding power is the support
06:00 PM tiwake: alright, figured it would be fine
06:00 PM tiwake: what about warping for larger parts? does it happen very much?
06:02 PM tiwake: cause I want to build an SLS that would be able to make an engine head... heh
06:03 PM Tom_L: it can
06:04 PM tiwake: Tom_L: can if I don't make the settings correct or something?
06:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/temp/prints/Ti_print2.jpg
06:04 PM tiwake: suppose it would also depend on the material
06:04 PM Tom_L: see the lego at the top?
06:04 PM Tom_L: that's TI
06:05 PM CaptHindsight: tiwake: the powders are typically held in an oven during printing
06:05 PM CaptHindsight: this help keep the materials from warping
06:05 PM tiwake: hmm
06:05 PM CaptHindsight: less power to melt/sinter is required
06:05 PM CaptHindsight: you don't typically hit the powders with a laser at room temp
06:06 PM tiwake: unless its something like sugar, yeah
06:06 PM CaptHindsight: often it is just below the melt temp by a few degrees
06:06 PM tiwake: hmm
06:06 PM CaptHindsight: sugar printers are more for fun than exact part tolerances
06:07 PM tiwake: well sure... heh
06:07 PM tiwake: for elaborate cake toppings
06:07 PM CaptHindsight: https://imgur.com/ukGDmqf the build chamber has the lid removed in this pic, it's on the left
06:08 PM tiwake: how powerful of a laser do you think I want? and probably a CO2 laser?
06:09 PM CaptHindsight: CO2 can do any colored materials
06:09 PM tiwake: aluminum?
06:09 PM CaptHindsight: sure
06:10 PM CaptHindsight: 1050nm diode lasers require dark powders
06:10 PM tiwake: I'd imagine a few hundred watts
06:10 PM tiwake: at least
06:11 PM CaptHindsight: depends on how fast you want to sinter
06:12 PM CaptHindsight: it's a matter of how many joules hits the material, so think watts over time
06:12 PM CaptHindsight: 200w in 1 second vs 20w in 20 seconds
06:13 PM CaptHindsight: er 10 seconds would be equal
06:13 PM CaptHindsight: also laser spot size
06:13 PM CaptHindsight: smaller the spot the higher the energy density
06:14 PM CaptHindsight: but there are practical limits on spot size vs wavelength
06:17 PM CaptHindsight: https://sci-hub.tw/10.1007/s40684-017-0037-7
06:17 PM CaptHindsight: Lasers in Additive Manufacturing: A Review
06:19 PM tiwake: I'll have to review it
06:21 PM Jymmm: Tom_L: https://i.imgur.com/DYASkL5.jpg
06:22 PM Tom_L: what's the coupler end fit?
06:22 PM Jymmm: I'm just going to wait 48 hours for the dope to dry.
06:22 PM CaptHindsight: propane flame thrower
06:23 PM Jymmm: Tom_L: Propane ACME on one end
06:24 PM Jymmm: Tom_L: this on the other... https://www.amazon.com/DozyAnt-Propane-Natural-Quick-Connect/dp/B06Y3HTK8W/
06:25 PM Jymmm: Tom_L: If you buy this ACME Tee, then you get four parts you can take apart and use as needed... https://www.amazon.com/dp/B00I8NS6Q6/
06:26 PM Jymmm: $13 for 2 vs $10 for one
06:27 PM Jymmm: CaptHindsight: Nah, tapping into the 250gal propane tank quick connect
06:28 PM Jymmm: for the generator and/or emergency propane heater instead of using the 5 gal tanks.
06:28 PM Tom_L: i got lantern adapters that conenct to the tank
06:28 PM Jymmm: Tom_L: I'm tapping into the 250gal tank, not bbq tanks
06:29 PM Tom_L: i don't have a 250 gal tank
06:30 PM Jymmm: Well, that's what II'm working on because it's a 50ft run
06:30 PM Jymmm: But, it'll be after the regulator, so what, 1/2 PSI I believe
06:31 PM Tom_L: https://www.pinterest.com/hubbard2089/painted-propane-tanks/
06:31 PM Tom_L: does it look like any of those?
06:31 PM Jymmm: https://66.media.tumblr.com/be3708c322daf1f66ee9fed03567fa99/tumblr_inline_pbbz92MWxd1rjqy8o_500.jpg
06:32 PM Jymmm: Tom_L: ^^^^^^
06:33 PM Tom_L: no style
06:34 PM Jymmm: I'm just hoping that 1/4 PU hose holds up
06:35 PM Jymmm: and is actually able to deliver the needed volume
06:35 PM Tom_L: why not use hard copper?
06:35 PM Jymmm: for propane???
06:35 PM Tom_L: well i mean the tube instead of a hose
06:36 PM Jymmm: Right now, this is a temporary/emergency way to tap into the big tank.
06:37 PM Jymmm: If there was an extended outage, I might run out of propane using 5Gal tanks. I dont have to worry about that now.
06:38 PM Tom_L: https://www.picclickimg.com/d/l400/pict/272836955001_/Coleman-Camp-Stove-Regulator-12-foot.jpg
06:38 PM Tom_L: i had one of those hooked up to a small heater for a while
06:39 PM Jymmm: Yeah, I have a hose too, but not to tap into the 3/4" black pipe, thus that setup I posted a pick of
06:39 PM tiwake: hmm
06:39 PM Jymmm: in a safe manner, and now able to connect to anythign that needs it using those ACME fittings
06:40 PM Jymmm: and I cna evacuate the hose before disconnecting
06:41 PM tiwake: if I had a line boring machine or jig of some sort for boring out the cam journals in ford overhead cam engines, I could get a fair amount of work
06:41 PM tiwake: anyone know about stuff like that?
06:48 PM Tom_L: we had one for VW cases
06:49 PM tiwake: Tom_L: was it a sunnen?
06:49 PM tiwake: or a custom thing?
06:50 PM Tom_L: custom iirc
06:51 PM Tom_L: did all the journals at once
06:51 PM tiwake: how was the machine set up?
06:51 PM Tom_L: you inserted it in the case and used a good size drill iirc
06:51 PM Tom_L: it's been a day or so since i've seen it
06:52 PM tiwake: heh
06:53 PM tiwake: now that I'm thinking about how things need to line up and stuff, I should be able to make something
06:54 PM Tom_L: https://www.youtube.com/watch?v=M1v-2HGfHOE
06:55 PM Tom_L: it was very similar if not that one
06:57 PM tiwake: interesting
06:57 PM Tom_L: we did dozens of em back in the day..
06:58 PM Tom_L: quite literally in and out in a day
06:59 PM Tom_L: did that and added stud inserts so the cylinder studs wouldn't pull out again
07:09 PM Tom_L: i'm not sure how that feed mechanism worked
07:12 PM Tom_L: https://www.thesamba.com/vw/classifieds/detail.php?id=1563369
07:12 PM Tom_L: out of stock
07:18 PM Tom_L: tiwake can you get oversize bearings for the camshaft bores?
07:28 PM tiwake: Tom_L: on the ford cam bearings, it just rides on the bare aluminum
07:29 PM tiwake: so need to cut oversize, weld it up, and cut back to size
07:29 PM tiwake: or something like that
07:30 PM Tom_L: what about warpage?
07:30 PM Tom_L: and oil passages
10:40 PM skunkworks: http://electronicsam.com/images/greenmachine/20190222_155408.jpg
10:44 PM Tom_L: did you have to swap encoders?
10:45 PM Tom_L: get that all tuned and you can send it to me for my spindle :)
10:45 PM skunkworks: I am in the process of swapping encoders.. the cui ones seem to suck/
10:45 PM skunkworks: for feedback anyways. we have one on the K&T spindle - for motor rpm. Seems to work fine in that situation.
10:46 PM Tom_L: that was 750w right?
10:46 PM Tom_L: iirc
10:46 PM skunkworks: yes
10:46 PM Tom_L: what's the black box?
10:47 PM skunkworks: middle picture?
10:47 PM Tom_L: yeah
10:48 PM skunkworks: it is a supply from an amc servo drive that was bad.. Has filtering and clamping.
10:48 PM skunkworks: (it is the dc supply for the power stage of the servo drive)
10:48 PM Tom_L: what voltage?
10:49 PM skunkworks: it is rectifying 120v - so it outputs about 160
10:49 PM skunkworks: ish
10:49 PM Tom_L: yeah
10:49 PM skunkworks: http://electronicsam.com/images/KandT/testing/stmbl/psi.png
10:49 PM Tom_L: that's what i wondered
10:49 PM skunkworks: cui encoder.
10:49 PM Tom_L: if it was direct off 120vac
10:49 PM Tom_L: nice
10:49 PM Tom_L: :)
10:50 PM skunkworks: normal optical encoder...
10:50 PM skunkworks: http://electronicsam.com/images/greenmachine/Screenshot_2019-02-24_14-59-15.png
10:50 PM Tom_L: didn't know they were sawtooth output
10:50 PM Tom_L: figured they'd be more square
10:51 PM skunkworks: - no - that is the jog of the servo drive - it is saw tooth because it is 1 per rev...
10:51 PM skunkworks: The noise is what I was showing
10:59 PM skunkworks: same tuning between the 2
