02:03 AM XXCoder: OHHH
02:07 AM XXCoder: https://www.youtube.com/watch?v=d6SbRkM0C3s
02:07 AM XXCoder: teamup to make space rocket door!
02:07 AM XXCoder: pink_vampire|2: bet you will like it!
02:07 AM pink_vampire|2: I saw all the videos about project egress
02:07 AM XXCoder: nice ok
02:07 AM pink_vampire|2: there is bunch of youtubers involved in that
02:07 AM XXCoder: yeah
02:07 AM pink_vampire|2: look at adam savage youtube channel about it
02:09 AM XXCoder: got link?
02:09 AM Deejay: moin
02:09 AM XXCoder: yo
02:09 AM pink_vampire|2: one sec I will get you one
02:10 AM pink_vampire|2: https://www.youtube.com/watch?v=dc5PpE56qPw
02:10 AM pink_vampire|2: i just watch that now
02:12 AM pink_vampire|2: https://www.youtube.com/results?search_query=%23projectegress
02:13 AM XXCoder: ugh broachin
02:13 AM XXCoder: i really hate broach
02:14 AM pink_vampire|2: https://www.youtube.com/watch?v=G0QcXwXZ-G4
02:14 AM pink_vampire|2: XXCoder: you right, we all need edm machines
02:17 AM pink_vampire|2: PewDiePie 97,838,541 subscribers
02:18 AM XXCoder: unfortunately edm cant do the shape im broaching
02:18 AM XXCoder: its teeth all around inside bore, with one tooth missing
02:18 AM miss0r: mornin
02:19 AM XXCoder: yo
02:19 AM miss0r: anything interresting happending?
02:20 AM XXCoder: its simple enough, place tighten then press button, oil bore and tool, position arm then hold it as start broaching
02:20 AM XXCoder: its numbers that get me. single job lot is 220 part or 330, depending on which part
02:20 AM miss0r: gah. that sounds boring
02:20 AM XXCoder: and it is
02:20 AM miss0r: how do you cope?
02:20 AM XXCoder: reading.
02:20 AM XXCoder: one or 2 page per part
02:21 AM miss0r: makes sense
02:21 AM XXCoder: average reader could maybe manage a paragraph. im fast.
02:21 AM miss0r: one would go bat shit just looking at the machine
02:21 AM XXCoder: yeserday i bropached 40 but then it was in 3 hours only
02:21 AM XXCoder: i could go obver 150 if I had 10
02:22 AM miss0r: sweet. I am a fast reader myself. I read a book a week/week and a half, before I go to sleep
02:22 AM miss0r: nice
02:22 AM XXCoder: book a week? thats slow for me
02:22 AM XXCoder: i normally read 3
02:23 AM miss0r: hehe, keep in mind I only read in bed before sleep ;)
02:23 AM XXCoder: :)
02:23 AM miss0r: sadly/luckily I don't have time to read during the day
02:23 AM XXCoder: i dont read much in bed usually 10 to 20 min
02:23 AM miss0r: in my case it all depends on the book :)
02:24 AM miss0r: if you havent, I can realy recommend jan guillou's 100 year story
02:25 AM miss0r: the first one of the series "bridge builders"... I must have read that one three times already
02:25 AM XXCoder: i have focus focus on scifi and fantasy
02:26 AM miss0r: I like that too. But man, did this story catch a hold of me :D
02:27 AM XXCoder: i highly recommand the three body problem
02:27 AM XXCoder: cant find bridge builder. auther name? so many books..
02:28 AM XXCoder: https://www.librarything.com/series/Remembrance+of+Earth%27s+Past
02:28 AM XXCoder: very different kind of writing, I thoughly enjoyed entire entires and wish I can wipe my memory so I can read em all for first time again
02:28 AM miss0r: plot sounds good
02:29 AM miss0r: I just finished the last one of jan guillou's series last night, so I am on the lookout for a new book
02:29 AM XXCoder: starts in china in past, cultural revolution
02:29 AM XXCoder: starts off like history, confused me, glad I didnt stop
02:30 AM miss0r: I think I shall aquire that book
02:34 AM pink_vampire|2: https://www.youtube.com/watch?v=FjYeiJ1q-Tk
02:34 AM pink_vampire|2: this is look like a very nice tool to make
02:40 AM XXCoder: some parts is apparently weood.
02:40 AM pink_vampire|2: what do you mean?
02:40 AM XXCoder: https://www.youtube.com/watch?v=DDttNgCpquo
02:40 AM XXCoder: maybe hes making casting mold bu dunno
02:41 AM pink_vampire|2: i thought you are talking about the king way tool
02:45 AM XXCoder: hes making a lot of metal parts now
02:46 AM XXCoder: no cnc just manual
02:46 AM pink_vampire|2: who?
02:46 AM XXCoder: guy i just linked to
02:46 AM XXCoder: oh a lathe
02:47 AM XXCoder: first time hes using milling rather than woodshop stuff
02:49 AM XXCoder: and now mill
02:50 AM XXCoder: damn hes doing everuthing
02:54 AM miss0r: meh... he is using wood?
02:55 AM XXCoder: and metal
02:55 AM XXCoder: yeah was wondering lol
02:56 AM XXCoder: but why not
02:56 AM miss0r: yeah... I've been watching quite a few of those moon landing replica videos lately...
02:56 AM XXCoder: better than https://www.youtube.com/watch?v=0Wk_0hZW520
02:56 AM miss0r: It feels wrong not to use a proper material for the job
02:56 AM miss0r: yeah...
02:57 AM miss0r: this old tony also made a part
02:57 AM miss0r: which could've worked
02:57 AM XXCoder: 3 parts yeah
02:57 AM XXCoder: though alum is little weak
02:57 AM XXCoder: in least seems so to me dunno
02:57 AM miss0r: for a second there, I thought diresta was going to do a cast with the 3D prints
02:58 AM miss0r: I was disapointed
02:58 AM XXCoder: i thought same
02:58 AM XXCoder: in least its wood, it wont break by simply staying in controlled climate room for years like plastic 3d printed
02:59 AM miss0r: yeah
02:59 AM XXCoder: but same time its abs
02:59 AM XXCoder: pla does break but abs is pretty damn tough
03:00 AM XXCoder: now watching redbeardbastor
03:00 AM miss0r: I still feel 3D printers are for people living in their parents basement
03:01 AM XXCoder: including myfordboy?
03:01 AM XXCoder: man his parents must be immortal
03:01 AM miss0r: :D
03:01 AM miss0r: nah... its just the feel I have for'em :)
03:01 AM XXCoder: lots of uses for 3d printing though
03:01 AM miss0r: yeah
03:01 AM miss0r: I'm considering one myself :D
03:01 AM XXCoder: many of em should be display and stuff, but also casting molds, etc
03:02 AM miss0r: one of those with a liquid and a HD tft screen
03:02 AM XXCoder: SLA? ehh
03:02 AM XXCoder: expensive material and weaker overall
03:02 AM XXCoder: I want SLS lol but so expensive...
03:02 AM XXCoder: fsm is cheapest of all sadly
03:03 AM miss0r: hehe :) A friend of mine works in a toolshop, where they just bought 4 3D printers at a serious price each. I can just have him print me stuff
03:03 AM XXCoder: smarter
03:03 AM XXCoder: thats only way to be cheaper than fsm, no printer
03:04 AM miss0r: yeah... At some point I was dreaming of doing castings here. But I also need to keep profit in mind, sadly.. :)
03:04 AM miss0r: so, printing the shapes and using them to do the sandmold
03:05 AM XXCoder: yeah
03:05 AM XXCoder: myfordboy have done it many times
03:05 AM XXCoder: he used to always hand make stuff then do finishing stuff
03:06 AM XXCoder: he now just 3d print then hand finish it with bondo sand paint etc
03:06 AM XXCoder: super glossy specifically
03:06 AM miss0r: yeah, its realy nice what he makes.
03:07 AM miss0r: Though, what I wanted to cast around here was iron...
03:07 AM miss0r: that takes a little more power than I feel comfortable with, I think :D
03:07 AM XXCoder: tough
03:07 AM XXCoder: didnt watch any iron casting but I know need much hotter temps
03:08 AM miss0r: yeah
03:17 AM miss0r: I need to get a move on - mother in laws birthday... see you later
03:18 AM XXCoder: later :)
03:26 AM Loetmichel: GNAH! now our local waste power plant lost it completely. It was open for private disposal of trash every saturday from 8 to 12 AM... now its only open one saturday a month. next date: aug.10, 2019. And then they wonder why people throw their tras on the road/in the woods. That was the last chance to get rid of household trash if your trascans are to small :-(
04:41 AM Tom_L: morning
04:47 AM XXCoder: hey
04:47 AM XXCoder: drat! didnt win that engine from myfordboy lol
04:47 AM XXCoder: jerry and perry won
04:47 AM XXCoder: trange how first names is very similiar
04:47 AM XXCoder: https://www.banggood.com/SH-02-Stirling-Engine-Model-Educational-Discovery-Toy-Kits-p-1155670.html this one
05:13 AM XXCoder: coool https://www.youtube.com/watch?v=OyhfQYHnJuM
05:29 AM XXCoder: that was fun video
06:18 AM jthornton: morning
06:22 AM XXCoder: yo
06:28 AM gloops: hmm, reverse direction of cap start motor, change wires on start winding?
07:05 AM gloops: well anyway, ive got a left handed shaper for the time being haha
07:29 AM Tom_L: yeah reverse the wire on the start winding
07:30 AM Tom_L: (single phase)
07:35 AM jthornton: well I just thought I might get debian 10 installed here this morning... nothing but issues
07:41 AM Tom_L: installing the OS or installing linuxcnc on the OS?
07:45 AM jthornton: well the first cd was not the non free one so I had to download it and burn it to a dvd and it looks like it just finished
07:49 AM jthornton: well no it's still working lol
07:49 AM XXCoder: what issues
07:51 AM jthornton: just various issues like cd would not boot then a sata plug was not fully seated so it took a while to figure out what the error message meant
07:52 AM XXCoder: oh thats fun
07:52 AM jthornton: then I downloaded a live dvd so that took longer and burning is taking longer just eating up all my free time this morning
07:55 AM XXCoder: i bet yeah
07:55 AM XXCoder: i never found anything more time draining than anything to do with os and installing it
07:56 AM XXCoder: careful or you will look up at clock and its hour later... and later find out it was actually 5 days and hour later
07:59 AM Elmo40: it takes time to set those 1's and 0's in proper order. ;-)
08:40 AM _unreal_: byond a shadow of a doubt, phone cord has become my fav sensor wire. for limits, and encoders etc... it flexes over and over with little risk of breaking
08:48 AM rmu: jthornton: ever tried https://wiki.debian.org/PXEBootInstall
08:49 AM rmu: combine with apt-cacher-ng
08:55 AM _unreal_: I think the last time I ever used pxeboot was in the late 90's
08:59 AM jthornton: never tried that
09:27 AM perry_j1987: morning
10:46 AM _unreal_: jthornton, are you responding to me? or rmu ?
10:54 AM skunkworks: _unreal_: I have used shielded stranded network cable...
10:55 AM Tom_L: unshielded is a bad idea
10:55 AM _unreal_: Tom_L, how so for limit switches
10:56 AM _unreal_: skunkworks, network cable=bad idea. its solid strand. subject to breaking
10:56 AM Tom_L: noise
10:56 AM _unreal_: phone cord is designed for flex
10:56 AM _unreal_: Tom_L, I dought many peole have ever had noise issues on limit switches.
10:56 AM _unreal_: not saying it doesnt happen. just saying its kind of a 1 in a million.
10:57 AM _unreal_: unless your dealing with finer control like hall sensors. and optical. then I could see maybe having faulse triggers
10:57 AM _unreal_: MAYBE
10:58 AM roycroft: not all network cable uses solid wire - i buy spools of stranded cat6 cable
10:59 AM jym: roycroft: What for?
10:59 AM roycroft: for connecting devices to switches/patch panels
11:00 AM roycroft: the solid wire cable is for permanent wiring runs that are attached to walls, etc.
11:00 AM roycroft: but anything that might move around should use stranded cable
11:01 AM roycroft: for the aforementioned reason
11:03 AM jym: roycroft: but are you using it for terminating on a RJ45? or just hookup wire?
11:05 AM roycroft: primarily for network use
11:06 AM roycroft: i don't often need 4 pair cables for general hookup use
11:11 AM jym: roycroft: ah ok
11:12 AM roycroft: the only point that i was making is that network cable is available in stranded as well as solid form
11:12 AM roycroft: i was not arguing for any specific application
11:23 AM jym: I wasn't either, was just curious as to stranded cat6 usage is all =)
11:24 AM roycroft: pretty much any pre-made ethernet cable you buy will use stranded wires
11:24 AM jym: I usually just crimp my own, but it's cat5e
11:25 AM roycroft: the only difference is how tightly the wires are twisted
11:25 AM jym: yeah, cross talk
11:29 AM _unreal_: If any of you are interested. I made a pcb design for using rj11
11:29 AM _unreal_: its designed as a limit switch setup. with a few simple options
11:29 AM _unreal_: I have a few versions as well
11:31 AM _unreal_: but they all have one thing in comon. a solder bridge and a JST header. I design them with 2 options. one allows it to be setup as a fixed function (the solder bridge). The jst header allows you to use a jumper or a lead wire to a switch. so you can enable/disable limit switches. comes in handy when triggering a limit switch and you need to get off it. :)
11:31 AM _unreal_: all the jumper does is break power supply
11:32 AM roycroft: rj45 connectors are cable type specific, btw - there are three types of those connectors
11:32 AM roycroft: one for flat stranded cable, one for round stranded cable, and one for round solid cable
11:44 AM perry_j1987: just watched the astronaut launch to the spacestation
11:44 AM * roycroft still remembers watching the moon walk live
11:45 AM roycroft: it's one of those singular memories in one's life
11:45 AM roycroft: i dug out my x-y table last night and it's both rusty and incredibly inaccurate
11:46 AM roycroft: i was going to mount it on my rotary table this morning and make my jig, but it appears i'll be spending much of the weekend cleaning it up and probably making the gibs flat and smooth
11:47 AM roycroft: as far as the inaccuracy goes, i suppose i'll probably have to use an indicator to measure travel, which sucks
11:48 AM roycroft: but the alternative would be to not use it, and do multiple setups for each part, which poses its own challenges
11:49 AM roycroft: and i have three parts that each have two points of rotation to machine - the stacked table setup is the only thing that makes sense to me
12:24 PM jthornton: all right debian 10 is now up and running on my dev pc
12:27 PM mmachines: looking for some beginner advice on making holes in Al tooling plate (CNC router not a mill)
12:27 PM mmachines: making holes for M4 screws - through hole not to be tapped.
12:27 PM mmachines: plate is 0.25" thick. I have 1/8" diameter cutter.
12:28 PM jthornton: a drill bit is the best tool to make a hole
12:29 PM mmachines: ok well I could put it on the drill press - I thought I would try the CNC
12:29 PM jthornton: is the router only one size collet?
12:29 PM mmachines: I have fixed size collets 1/8", 1/4", 3/8", 1/2"
12:30 PM jthornton: I would first drill the hole with a drill bit then open it up with the end mill
12:31 PM mmachines: ok I see. I wasn't sure if I should peck drill then try spiral or spiral drill from the start.
12:32 PM gregcnc: RPM?
12:32 PM jthornton: I'd bet way too fast rpm
12:32 PM gregcnc: for drilling probably
12:32 PM mmachines: I can manually select RPM down to 10K (Porter Cable 8902)
12:33 PM gregcnc: spiral with an end mill is fine, i did that for a long time
12:33 PM gregcnc: make sure you can get the chips out
12:35 PM mmachines: ok thanks
12:36 PM gregcnc: start with a small helix angle and feedrate and see what the machine is capable of
12:36 PM jthornton: yea I would drill them first and take light doc so the end mill does not flex
12:37 PM jthornton: bbib gotta shut down and connect up some hard drives to this pc
01:10 PM jthornton: hmm if I connect a second hard drive up debian 10 either won't boot up or it boots the os on the second hard drive...
01:11 PM jthornton: I wonder if installing from a flash drive is the issue...
01:12 PM Tom_L: write over the boot sector of the 2nd drive
01:12 PM Tom_L: i've had to do that before
01:12 PM jthornton: I don't think that is the problem because if there is no os it just hangs
01:20 PM Tom_L: i write 0000 to the first few sectors then bail out so it doesn't write the whole disk
01:20 PM Tom_L: very effective
01:20 PM Tom_L: grub didn't wanna let go of it for some reason
01:24 PM jthornton: there are some suggestions about fstab being wrong and the data drive being auto mounted which makes some sense
02:05 PM jthornton: the solution was to install the grub customizer and uncheck search for other operating systems
02:06 PM jthornton: except I can't mount the drive...
02:19 PM jthornton: hmm the 2TB drive mounts...
02:44 PM perry_j1987: just got done watching NYCCNC's Starrett factory tour
02:45 PM perry_j1987: that place is huge
03:11 PM skunkworks: x and y have about .0025 backlash...
03:15 PM andypugh: _unreal_ was the video any help?
03:15 PM _unreal_: andypugh, remind me which video again? you've posted a few
03:15 PM Nick001-Shop: Can I use a 7i29 card with resolvers with 5i23 & 7i49 & 2-7137TA cards?
03:16 PM skunkworks: .0005 error over 7 inches.. I can live with that.. http://electronicsam.com/images/greenmachine/IMG_20190720_150919.jpg
03:16 PM _unreal_: skunkworks, I'm designing a new probe right now
03:17 PM skunkworks: _unreal_: I am happy with this one :) it seems close enough for this machine..
03:17 PM _unreal_: how much did it set you back?
03:17 PM _unreal_: $150 ish?
03:18 PM skunkworks: I would have to ask - dad scored it from a local online auction.. I am thinking 50ish or so
03:19 PM skunkworks: we have one for each running machine. they are so nice.
03:19 PM _unreal_: cool
03:20 PM skunkworks: The other 2 are 'big' http://electronicsam.com/images/KandT/prhttp://electronicsam.com/images/greenmachine/IMG_20190720_150919.jpghttp://electronicsam.com/images/greenmachine/IMG_20190720_150919.jpgobe/PROBE2.JPG
03:20 PM _unreal_: interesting
03:20 PM _unreal_: ya I'm building a tiny one
03:20 PM _unreal_: trying to anyways
03:21 PM skunkworks: I started to - then we found cheap ones on ebay
03:25 PM _unreal_: My issue is I have to have a really low profile one for my machine
03:25 PM _unreal_: and I dont have one yet
03:25 PM _unreal_: My rope and anchor design on a spoon came out good BTW
03:25 PM _unreal_: !! good as it could be I should say
03:25 PM skunkworks: rope and anchor?
03:27 PM _unreal_: https://drive.google.com/open?id=1sykAFGCVxiSlMvAsu3eu47pUtPO9t10d
03:28 PM _unreal_: to mill onto a wooden spoon
03:28 PM _unreal_: came out decent
03:29 PM _unreal_: had some depth issues here and there but thats because the @#$%@#$%$#@ dollar store spoons are crap and there thickness changed a lot
03:29 PM roycroft: dollar stores are to be avoided whenver possible
03:29 PM jthornton: well that
03:29 PM roycroft: they are nothing more than mini wal*marts
03:29 PM jthornton: 's nice all my stuff I copied to the 1TB is not there
03:30 PM roycroft: at least you copied it and not moved it
03:30 PM jthornton: I just installed debian 10...
03:30 PM roycroft: i've had mixed results with buster
03:30 PM skunkworks: uh oh...
03:30 PM pink_vampire: _unreal_, look like an interesting design for a spoon
03:30 PM _unreal_: buster?
03:30 PM roycroft: 50% of my upgrades went swimmingly
03:30 PM _unreal_: thanks pink_vampire
03:30 PM roycroft: buster = debian 10
03:31 PM skunkworks: latest debian
03:31 PM _unreal_: I'll post a picture when I get it
03:31 PM roycroft: 50% of my upgrades have blown up magnificently
03:31 PM roycroft: fortunately all the upgrades so far have been on non-production machines
03:31 PM jthornton: what issues did you have with 10?
03:31 PM roycroft: the 50% that failed could not find the lvm volumes after rebooting with the new kernel
03:32 PM roycroft: and i've had no time to dig into things to try to figure out what happened
03:32 PM _unreal_: picture of the spoon will be uploaded in a min
03:32 PM roycroft: but they would start rebooting, then the kernel would complain that it can't find any lvm volumes, and since / is on an lvm volume, things would come to a screeching halt
03:32 PM jthornton: I had to install the grub customizer and turn off look for other os's so I could add another drive
03:32 PM _unreal_: There it is https://drive.google.com/open?id=1D-k13xqrv-9Z-6ok8anqo4-VMt7iCLG4
03:33 PM roycroft: afaik there is no rhyme nor reason to half working and half not working
03:33 PM roycroft: i have a very standard installation procedure that i use for every machine
03:33 PM gloops: 6 jaw chuck https://www.facebook.com/marketplace/item/106684226933571/
03:33 PM roycroft: including standard filesystems with standard sizes
03:34 PM roycroft: every vm gets the same basic install
03:34 PM roycroft: they all use xfs as the filesystem
03:34 PM roycroft: i'll add a second volume group for service-specific filesyystems such as /var/www/html or /var/lib/mysql
03:35 PM roycroft: but every vm gets the exact same standard os installation
03:35 PM roycroft: so i don't get why half failed and half worked fine
03:35 PM roycroft: my sample size is small at this point - i've had three successes and three failures
03:35 PM roycroft: but it's still odd
03:36 PM jthornton: now if I can remember how I changed the drive name from /media/john/3c64298b-e466-415c-8764-05f2537a2586 to /media/john/storage???
03:36 PM jthornton: yea that is odd
03:37 PM pink_vampire: _unreal_, I can't believe this CNC did such an amazing finished wooden spoon
03:37 PM _unreal_: :)
03:39 PM _unreal_: the rope design would have shown better but the bamboo thickness is not constant
03:39 PM jthornton: Partition 2 does not start on physical sector boundary. that don't look good
03:39 PM pink_vampire: _unreal_, I thought you about to do like 3D machining, or modifying the original spoon
03:39 PM * roycroft has a bit of rust removal and cleanup to do on the x-y table still, so it will be a while, but he would still welcome suggestions on aligning that table with the primary one
03:40 PM _unreal_: pink_vampire, I want to do somoe 3d milling but I have yet to figure out how to get fusion360 to generate a 3D nc path
03:40 PM _unreal_: I have a grape vine design thats in STL that I need to convert.
03:40 PM _unreal_: and scale down to about 1"
03:40 PM pink_vampire: same as 2d
03:40 PM roycroft: _unreal_: andypugh posted a link to a grabe video last night for you just as you were leaving
03:40 PM roycroft: did you see the link?
03:41 PM roycroft: grape
03:41 PM roycroft: he said he made the video specifically for you
03:42 PM pink_vampire: you salect the facea you want to cut, and defind a machining boundaries and from that point it is exactly like 2d
03:43 PM _unreal_: oh ya that yes I did watch that
03:43 PM pink_vampire: it is very easy,
03:48 PM _unreal_: right now I'm kind of looking over my window sholder so to speak ;) I'm designing a smaller better touch probe design. like my last one but even simpler and smaller
03:48 PM _unreal_: but same number of parts.
03:48 PM _unreal_: and number of parts being very few
03:48 PM pink_vampire: https://i.imgur.com/mTHrVJs.png I did this Haammer handle in HSM few years ago
03:49 PM pink_vampire: hammer
03:49 PM pink_vampire: _unreal_ ^
03:49 PM _unreal_: hsm?
03:51 PM pink_vampire: HSM is an actual CAM software that integrated into SolidWorks
03:56 PM _unreal_: ahh
04:01 PM pink_vampire: _unreal_, look up hsmworks and hsmexpress
04:04 PM _unreal_: ugh.... I have to enter new milling bits. just got some new bits in themail
04:04 PM pink_vampire: any idea how to make 4x60mm strips from 3mm acrylic sheet?
04:05 PM _unreal_: ?
04:05 PM _unreal_: as in cut them?
04:05 PM pink_vampire: 600mm***
04:05 PM _unreal_: ?
04:05 PM skunkworks: laser?
04:05 PM _unreal_: 60 or 600
04:05 PM skunkworks: ;)
04:05 PM pink_vampire: 4x600
04:05 PM _unreal_: pink_vampire, what level of accuracy do you need?
04:06 PM Deejay: gn8
04:06 PM _unreal_: there are different methods of cutting but melting is the biggest issue
04:07 PM pink_vampire: good enough to the point that I can weld it with the solvent
04:07 PM _unreal_: pink_vampire, I'd say a table saw VERY thin table saw blade and deep teeth
04:08 PM _unreal_: I just got these in the mail https://www.amazon.com/gp/product/B07C6TCXJ9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
04:11 PM pink_vampire: now you need to find a garbage bin
04:12 PM andypugh: _unreal_: Actually, I am fuzzy now on if it was uou who was trying to make G-code from STL and was finding all the tutorials were for a different UI. I am horrible at keeping track of names.
04:13 PM _unreal_: yes me and grape
04:13 PM pink_vampire: for drilling just use a twist drill, those burr style drills just break too easy, and get clogged very fast
04:14 PM pink_vampire: even with my 60,000 rpm I have very hard time running them reliably
04:15 PM pink_vampire: _unreal_ ^
04:17 PM _unreal_: pink_vampire, those are rotory rasps
04:17 PM _unreal_: they should not break easy
04:17 PM _unreal_: there not drill bits
04:18 PM _unreal_: they mill fiberglass like butter
04:18 PM _unreal_: though the really small one's in the kit need a very slow feed rate
04:19 PM andypugh: So not _entirely_ like butter then?
04:20 PM _unreal_: !@#$!@#%!@#$
04:20 PM _unreal_: freaking software keeps crashing
04:21 PM pink_vampire: _unreal_, what do you want to do with them?
04:23 PM pink_vampire: actual machining on composite material? or just engraving and such?
04:23 PM _unreal_: PCBS
04:23 PM _unreal_: pcb's
04:24 PM _unreal_: I've already tested and these mill pcbs like butter
04:24 PM _unreal_: and dont ware down
04:24 PM pink_vampire: _unreal_, well that's amazing
04:25 PM skunkworks: _unreal_: for isolation cutting?
04:25 PM pink_vampire: I'm just using regular fluted end mills
04:26 PM pink_vampire: _unreal_, what RPM and feeds and speeds are you using?
04:28 PM skunkworks: I have used these for isolation milling... https://www.precisebits.com/products/carbidebits/scoreengrave.asp
04:29 PM skunkworks: happy with them - but I don't know if I would do that again.. So inexpenive to have them done now
04:29 PM _unreal_: my spindle has a max of 12k
04:29 PM _unreal_: I run at max
04:30 PM _unreal_: pink_vampire, look up rotor zip rotory rasps
04:30 PM _unreal_: rotozip
04:30 PM _unreal_: or dremel. but the rotozip one's are cheaper
04:30 PM _unreal_: you can cut fiberglass with them all day and they will NOT ware down
04:30 PM pink_vampire: it is designed to cut through sheetrock not composites
04:30 PM _unreal_: though the 1/8 shank one's are very prone to breaking if they chatter
04:31 PM _unreal_: pink_vampire, I'm in the marine industry that is what we use. AND they are designed for grout
04:31 PM _unreal_: grout is ROCK rock is like diamond.
04:31 PM _unreal_: fiberglass is "glass" there for its like rock
04:32 PM _unreal_: anything that works on cutting a cinderblock, or tile works on fiberglass
04:32 PM pink_vampire: the only RotoZip that I know about is the stuff that you cut holes in sheetrock
04:32 PM _unreal_: :)
04:32 PM _unreal_: https://www.lowes.com/pd/dremel-steel-grout-removal-bit-accessory/1000348185?cm_mmc=shp-_-c-_-prd-_-tol-_-google-_-lia-_-129-_-rotaryandoscillatingtools-_-1000348185-_-0&kpid&store_code=1069&gclsrc=aw.ds&&k_clickID=go_1736136440_67585270066_338469082292_aud-363972024615:pla-424719174430_c_9012012&gclid=CjwKCAjw98rpBRAuEiwALmo-yrmsP98-whzRRNDc5Tog2SsICKXEA1xyx8o51xZOSxX7swnSUGkgCBoCeQkQAvD_BwE
04:33 PM _unreal_: You can run these till the cows come home on fiberglass and the will never break or ware out
04:33 PM _unreal_: they do NOT cut wood well
04:33 PM _unreal_: FYI
04:33 PM _unreal_: https://www.lowes.com/pd/rotozip-steel-1-8-in-cutting-bit-accessory/1086945?cm_mmc=shp-_-c-_-prd-_-tol-_-google-_-lia-_-129-_-rotaryandoscillatingtools-_-1086945-_-0&kpid&store_code=1069&gclsrc=aw.ds&&k_clickID=go_1736136440_67585270066_338469082292_aud-299487635210:pla-424719174430_c_9012012&gclid=CjwKCAjw98rpBRAuEiwALmo-yjZ3DXNN_6-6G052NdznaRnxbb3E7qYeenGqVGh1uG0jNg6tbhtudhoC7_cQAvD_BwE
04:34 PM _unreal_: dirt cheap
04:34 PM _unreal_: you can get them in larger sizes as well
04:34 PM _unreal_: the 1/4" version that I use in my router at work. can cut solid fiberglass panel like its butter
04:35 PM _unreal_: I've been using the same bit for about 2 years. they will break LONG before they ware
04:35 PM _unreal_: though they dont cut metal and they burn if you hit wood
04:38 PM pink_vampire: very interesting! I was always stick to a regular end mills and never had a problem, the only thing that I'm not really sure about those rasps, is how do you holding a dimension, it might be a good solution for roughing but I can't see how you can get a nice straight and accurate edge on the part
04:39 PM Tom_L: .
04:44 PM pink_vampire: ...
04:46 PM roycroft: you get a raspy edge with them
04:46 PM roycroft: maybe you like that
04:59 PM _unreal_: they do produce a raspy edge
04:59 PM _unreal_: like a very light saw tooth finish
04:59 PM _unreal_: but they are amazing on hard materials. dont work on metals
05:27 PM _unreal_: shhhhh
06:09 PM _unreal_: milling one of my limit switches now
06:09 PM _unreal_: err limit switch interfaces
06:13 PM _unreal_: where did everyone go?
06:16 PM andypugh: What? Everyone. There’s billons of them.
06:17 PM XXCoder: oh yes everyone. they left in huge space ark. sun will nova in few years
06:17 PM XXCoder: i dont relaly care so im staying
06:19 PM andypugh: I thought it was to escape a mutant star goat?
06:20 PM * jthornton was spending quality time with the chickens
06:21 PM _unreal_: jthornton, didnt ruffle any feathers did you?
06:22 PM andypugh: So, I have a 4GB SD card image for the Pi4 I want to share. Where to put it?
06:22 PM _unreal_: pi4?
06:23 PM _unreal_: I'll upload the photos in a few.
06:23 PM andypugh: Too big for github. It’s bigger than anything else in www.linuxcnc.org/iso by a factor of 4, so that seems a bit of a stretch
06:23 PM jthornton: linuxcnc.org/dists
06:23 PM _unreal_: andypugh, google drive
06:23 PM jthornton: really, why so big?
06:23 PM andypugh: My google drive is full of Gmail
06:23 PM _unreal_: so pay them $2 USD and get 100gb
06:24 PM _unreal_: or setup your own FTP
06:24 PM _unreal_: I'm on a mission now to find one of those 12v "car" vacuum cleaners
06:24 PM _unreal_: I want to use it for my cnc machine
06:24 PM andypugh: jthornton: I spent ages making it smaller! It was a 32GB image of a 32GB SD card, but I downloaded a thing to make it fit on an 8GB SD card and then zipped it to 4GB
06:25 PM _unreal_: I figure HELL I have plenty of 12v psu's and those things are very quite. and not very powerful
06:25 PM _unreal_: and small
06:25 PM _unreal_: great for clearing dust
06:25 PM andypugh: And rated to run for 15 minutes a month
06:26 PM _unreal_: damn straight 15 hour minuts a month
06:26 PM _unreal_: I'll likely swap out the motor for something a little more worthy
06:27 PM _unreal_: 12min to go
06:27 PM _unreal_: I want to speed the feed rate up sooooooooooooooooooooooooooooo bad
06:27 PM _unreal_: but I cant because that carbide cutter is 1/4" long at .6mm
06:27 PM _unreal_: no taer
06:27 PM _unreal_: taper
06:27 PM jthornton: raspbian full zip is only 2GB
06:27 PM XXCoder: andypugh: oh dont worry about that goat, nova will end it
06:28 PM _unreal_: I take that back. its .5" long and 1/4" flute
06:28 PM jthornton: ah you built it on a 32GB card...
06:29 PM andypugh: jthornton: Yes, but shrunk it back down. It does have LinuxCNC-dev on it, and extra kernels.
06:29 PM jthornton: ah yea kernels take up a lot of room
06:30 PM _unreal_: 7min to go
06:30 PM andypugh: I could remove the non-RT one, but I am not sure how to do so cleanly
06:31 PM jthornton: do you have the synaptic package manager installed?
06:31 PM andypugh: And “cleanly” can be a problem, I already removed the GUI when trying to purge libre-office earlier.
06:31 PM _unreal_: lol
06:31 PM jthornton: oh my
06:31 PM _unreal_: andypugh, I know that one
06:31 PM _unreal_: I've practiced it a few times
06:32 PM andypugh: (It was lovely and small, and did actually have lxrt (?) if you tried “startx” when it finished booting to the command line
06:32 PM jthornton: got to see if I can recover all my files from a drive that I copied to when I should have copied them to the nas
06:33 PM andypugh: jthornton: I think that the 2GB images are the “lite” version, which downloads Gnome Desktop if you later choose that in the rapi-config utility
06:34 PM jthornton: the lite one is 368.4MB
06:34 PM jthornton: the regular one is 1.1GB
06:35 PM jthornton: hmm they have raspbian buster now
06:35 PM andypugh: Yes, this is Buster I am taliking about
06:36 PM jthornton: and they are all much smaller... 426MB to 1945MB
06:36 PM skunkworks: andypugh: what kinda latency are you getting with rpi4?
06:36 PM jthornton: time for the cricket rodeo with the chickens
06:36 PM andypugh: And maybe I could, if I was good at this stuff, and had nothing better to do, and could be bothered, make this smaller than 4GB. But I suspect that no more than 2 people want this anyway.
06:37 PM _unreal_: shit
06:37 PM _unreal_: well the milling is great but I forgot that the traces are two small for that bit
06:37 PM andypugh: skunkworks: About 30µS
06:37 PM skunkworks: wow - amazing.. that would do software stepping...
06:37 PM andypugh: It’s absolotely usable,
06:38 PM skunkworks: how many gpio does it have?
06:38 PM skunkworks: (I know there isn't a driver yet0
06:39 PM _unreal_: back in a bit running to the good will to see if there are any of those vac's
06:39 PM _unreal_: fingers crossed
06:39 PM andypugh: I don’t know without doing a Google search. Cerainly enough to fill a DB25 as I made some adaptors years ago
06:39 PM skunkworks: andypugh: oh - I remember that.. you had one at stuarts shop
06:40 PM andypugh: I had _20_ at Stuarts shop, and gave them away.
06:40 PM andypugh: So you might have one.
06:40 PM skunkworks: I don't think I took one..
06:40 PM skunkworks: (didn't think I would ever play with a pi...
06:41 PM skunkworks: I did score a mesa ethernet board. (which we used on the matsuura..)
06:42 PM andypugh: There are 28 actual GPIO pins, Some of which also do UART and SPI.
06:43 PM skunkworks: so - smart serial?
06:43 PM skunkworks: smop
06:43 PM andypugh: But there is also the Mesa 7C80
06:43 PM skunkworks: sure
06:43 PM skunkworks: does the eithernet and wireless play well with realtime?
06:44 PM andypugh: Soft-sserial is a very interesting idea. As is EtherCAT
06:44 PM andypugh: That is yet to be determined.
06:45 PM andypugh: Hakan on the forum has a 7i76E hooked up to the Pi Ethernet, and it seems to be working. They have moved the Ethernet off the USB bus.
06:45 PM andypugh: So it is possible that it might work.
06:51 PM andypugh: Cool. Several months old, but a simulation of the very first web broswer running in your web browser: https://worldwideweb.cern.ch/browser/
07:09 PM _unreal_: no luck at goodwill. did find a $300 sound bard for $20 and an apple usb wall wart charger for a buck
07:17 PM _unreal_: Well that settles it. i'm going to have to redraw that PCB for use with a .6 end mill
07:26 PM Tom_L: andypugh you could post it on my server but not sure how you'd get it there
07:26 PM roycroft: the gibs for this x-y table look like they were plasma cut out of a piece of rusty bedframe
07:27 PM * roycroft is spending more time on this project than he hoped he would need to
07:27 PM andypugh: _unreal_: The Apple wall-warts are the best
07:27 PM _unreal_: yep
07:27 PM _unreal_: this one My daughter is going to be given a @#%@!#$%@#$# ever touch it lecture
07:27 PM andypugh: (according to a YouTube video that measured regulation and ripple)
07:28 PM _unreal_: andypugh, you know they are good when they are heavy :)
07:28 PM * _unreal_ starts blinking
07:28 PM pink_vampire: I don't know why the IRC is so unreliable and keep disconnecting all the time
07:28 PM _unreal_: I am dumb
07:28 PM _unreal_: I just finished setting up my starboard scraps and didnt put a waste board under it
07:28 PM XXCoder: llooks like your connection has some kind of issue
07:29 PM XXCoder: pink
07:32 PM pink_vampire: I'm on the phone and everything work fine other than the IRC, I was trying that wifi network and also the cellular network, and even in the computer is keep disconnected, are there other programs work fine, I'm using Whatsapp Signal Discord Slack and Skype, and none of them have any issue
07:33 PM pink_vampire: it is almost impossible to get more than 12 hours connection to the IRC without getting disconnected, I've no idea what happened, back in the days it was very very reliable
07:33 PM XXCoder: yeah not sure. been very steady here
07:35 PM pink_vampire: I wish it was a way to combine several protocols did the same chat, see if you have a problem with IRC can connect with other things but to get to the same chat
07:35 PM pink_vampire: did = to*
07:39 PM andypugh: IRC is very stable for me.
07:39 PM andypugh: pink_vampire: Which client do you use?
07:39 PM andypugh: Actually, that’s a daft question, I will know nothign about your client
07:40 PM andypugh: But you could try a different one.
07:40 PM andypugh: (I use Colloquy, but that’s probably not on your platform)
07:41 PM pink_vampire: on the phone it is Yaaic, and on the computer is kvirc
07:42 PM pink_vampire: I guess the minimum is if the connection got disconnected it should reconnect
07:42 PM XXCoder: mine is explictly set to NOT recommect
07:42 PM andypugh: On the computer, why not try running another couple of clients in parallel, and se if they all go down at the same time?
07:43 PM andypugh: (Colloquy is Mac-only so I supect no good for you)
07:45 PM pink_vampire: the funniest thing is when it's disconnect its disconnect in the phone and also in the computer and the computer use the internet of the house and the phone use cellular network and those are two different clients on two different platforms
07:47 PM andypugh: Hmm, then that rather points at a server-side problem.
07:49 PM pink_vampire: what do you mean by server-side I'm connecting do freenode like I do for years
07:50 PM pink_vampire: here's an update on the lvds cable: https://i.imgur.com/QCqkqzl.jpg
07:51 PM pink_vampire: 15 wires to go
07:53 PM andypugh: Freenode seems to “net split” quite frequently.
07:54 PM andypugh: ref the LVDS: M20 crimp terminals?
07:54 PM andypugh: Not sure what I am seeing, do the bottom set loop round to join the bundle?
07:55 PM andypugh: (The insulation looks like you have soldered rather than crimped?)
08:03 PM pink_vampire: yeah, I opened the crimper than a point of a needle, and then re crimp the new wires and add a little bit of solder
08:04 PM cerna: <pink_vampire "I wish it was a way to combine s"> Maybe plumbed Matrix room? Or something like it.
08:05 PM pink_vampire: cerna, not sure what do you mean by that
08:06 PM andypugh: pink_vampire: You can buy the crimps, and the tool. (I have both as I use these for connecting Mesa cards. Oh, and because I need no excuse to buy tools)
08:06 PM cerna: Matrix IM, matrix.org, hazzy at QtPYVCP is using it. It basically bridges Matrix IM rooms to IRC channels.
08:07 PM cerna: Other protocols too.
08:07 PM cerna: You can then connect on both ends.
08:08 PM pink_vampire: what I meant is to combine all the big platforms WhatsApp Discord slack and the IRC and create one big room so people can connect from whatever platform they want and get the same chat
08:09 PM andypugh: Ah, but you need to understand that those platforms are all in it for the money, and plan to, themselves, be the one true platform.
08:09 PM Rab: Wasn't XMPP something like that?
08:10 PM cerna: Well, you can. There is bridge for IRC, Slack, Discord. I am using Matrix as an IRC bouncer.
08:10 PM hazzy-m: I don't think matrix is in it for money
08:11 PM andypugh: pink_vampire: https://www.mouser.co.uk/Search/Refine?Keyword=M20-1180042
08:11 PM hazzy-m: Yeah, I'm here from the matrix mobile app
08:13 PM andypugh: pink_vampire: https://www.amazon.com/IWISS-IWS-3220M-Connector-0-03-0-52mm²-Ratcheting/dp/B078WPT5M1/ref=sr_1_8?keywords=d-sub+crimp&qid=1563671277&s=gateway&sr=8-8
08:13 PM pink_vampire: andypugh, looks like a nice find
08:14 PM pink_vampire: where have you been a week ago??
08:14 PM andypugh: Sorry!
08:15 PM andypugh: Buy sime for next time?
08:16 PM andypugh: Anyway, sleep beckons.
08:16 PM pink_vampire: hazzy-m, so let's say you want to share an image you just click on the phone and share it or you need to go to third-party website and upload it and then come back to the IRC and then share the url?
08:18 PM Wolf__: irc was around before cellphones and digital cameras were common…
08:18 PM XXCoder: yep
08:18 PM hazzy-m: Can just click an icon next to the message box to take a picture, on IRC it will show as a link, on riot matrix client it shows imbedded
08:19 PM XXCoder: it existed during era that websites is plain and simple
08:19 PM * hazzy-m uploaded an image: ima_8bb4297.jpeg (68KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/qioqAAifQUWjMJrnNvWkcnsO >
08:20 PM Wolf__: thats pretty cool
08:20 PM hazzy-m: I still prefer IRC, but matrix is really convenient since I travel a lot and can use my phone
08:20 PM Rab: hazzy-m, nice 547+1A4. I gave away that exact combo not too long ago, in less nice condition.
08:21 PM Wolf__: some day I’ll bother to setup a zrc
08:21 PM hazzy-m: Rab: thanks, it's a fantastic scope!
08:21 PM XXCoder: https://bigthink.com/technology-innovation/protein-from-air that is insane.
08:21 PM Rab: hazzy-m, also the elite tilting Scopemobile.
08:23 PM * hazzy-m uploaded an image: ima_492e5b4.jpeg (129KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/LgnGSABYSoomYrWxMFPXTQTS >
08:24 PM hazzy-m: I have quite a few other scopes, but this is my favorite and in best condition
08:24 PM Rab: I always wanted to put 2x 1A4s in a 555 to make an 8-channel beast.
08:24 PM hazzy-m: It was originally from Y22 at oak ridge
08:24 PM pink_vampire: can you delete those images?
08:24 PM hazzy-m: That would be sweet!
08:25 PM hazzy-m: pink_vampire: yes, not sure what happens in IRC though, links will remain obviously
08:26 PM XXCoder: delete it
08:26 PM Rab: hazzy-m, excellent. I had a couple scopes with NASA tags, maybe from Ames or one of the other less-noteworthy sites.
08:26 PM XXCoder: ill check if it still works for irc
08:27 PM pink_vampire: yeah I know that the links will remain for example on Discord you can delete the image but the links sometimes stay so if you have the URL you can still see the image even if you deleted it
08:27 PM hazzy-m: Ok second one is deleted
08:27 PM XXCoder: still works
08:28 PM XXCoder: force reloaded still works
08:28 PM pink_vampire: if you want to upload an image to imagur from the phone it's basically force you to make a hidden post out of it
08:28 PM XXCoder: so basically dont upload private images
08:29 PM hazzy-m: So must stay on the server for some time, wonder how often they purge
08:29 PM hazzy-m: Or if they do
08:32 PM XXCoder: dunno
08:32 PM hazzy-m: Rab: we have a "diaper changing table" that has a property of the AEC tag on it lol
08:33 PM _unreal_: aec?
08:35 PM hazzy-m: Atomic Energy Commission
08:40 PM hazzy-m: It was once a desk at Los Alamos in the 40s before it became a changing table in the early 50s, and it remains that to this day
08:42 PM _unreal_: I'm going for an other beer. any one else want one?
08:43 PM hazzy-m: _unreal_: I'll take one, thanks.
08:45 PM _unreal_: miller high life, here ya go...
08:45 PM hazzy-m: just what I wanted cheers!
08:47 PM _unreal_: sigh...
08:47 PM _unreal_: I'm milling a new waste board
08:47 PM _unreal_: my other one is just far to chewed up
08:48 PM _unreal_: I should really reorder that file
08:48 PM _unreal_: to zig zag
08:48 PM _unreal_: rather then finish at the far end. come all the wya back to zero to start popping holes again
08:49 PM _unreal_: only a 15min file
08:52 PM _unreal_: interesting how my motor controller PSU fan only seems to turn on when the machine is just iddling doing nothing
08:52 PM _unreal_: ok I have a fresh waste board
08:52 PM _unreal_: kind fo
08:52 PM _unreal_: of
08:53 PM cerna: Anybody here hacked ELF file sections?
08:58 PM _unreal_: elf file?
08:59 PM cerna: Executable and linkable format. I am playing with it from 20.30, now it's 3.54 and I am KO.
09:00 PM _unreal_: ya almost 10pm here
09:16 PM _unreal_: finally new waste board down
09:16 PM _unreal_: almost hate to mill into a new waste board after the effort it takes to build one
09:16 PM _unreal_: I really should automate it a little more though :/
09:27 PM Tom_L: _unreal_ you didn't use my zig zag file?
09:28 PM Tom_L: i use an aluminum plate and just face it off for a clean look
09:28 PM _unreal_: I did but I have since changed the number of holes
09:29 PM _unreal_: I have a better aluminum plate
09:29 PM _unreal_: then I did before
09:31 PM _unreal_: there was a discrepincy between my win software and turbocnc
09:31 PM _unreal_: and even though the numbers weere right. my hole spacing was off
09:32 PM _unreal_: i had to rebuild the plate so I changed the number of holes. I found that the number that was there before was good but the average spacing need was diffeent
09:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Sacrificial_plate.jpg
09:36 PM Tom_L: it was on my sherline
09:37 PM hazzy-m: Tom_L: how is your mill holding up? running good still?
09:37 PM Tom_L: runs fine, haven't used it in a bit since i can't get to it right now
09:37 PM Tom_L: basement contents are in the garage after a flood
09:38 PM Tom_L: hazzy, how's things with you?
09:39 PM hazzy-m: ouch, thats not good
09:39 PM Tom_L: qtpyvcp n all...
09:39 PM hazzy-m: Both my mills are in the same predicament, but its not because of a flood, just too much junk lol
09:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/basement/water_heater_split.jpg
09:39 PM Tom_L: decided to give up in a big way
09:41 PM hazzy-m: whoa! That does not happen often, saw one like that once but I thought it must have frozen, maubey not ...
09:42 PM hazzy-m: cranking along, been busy with day job so qtpyvcp and play time has been limited
09:42 PM Tom_L: no warning at all
09:42 PM Tom_L: i know the feeling
09:43 PM Tom_L: finally got the walls dry and started cleanup
09:43 PM _unreal_: sigh... waiting for my file to finish milling
09:43 PM hazzy-m: do you think it was a pressure surge?
09:43 PM Tom_L: i have no idea
09:43 PM Tom_L: i wouldn't think so
09:44 PM Tom_L: it would certainly be a first here
09:44 PM _unreal_: most likely rust
09:44 PM _unreal_: and a bad weld seam
09:44 PM _unreal_: seeing as how it was perfectly vertical I would easly guess that was along the weld
09:44 PM _unreal_: and old and rusted
09:45 PM hazzy-m: whithin the past 10yrshere the code has changed to require a pressue tank on the watter heater to absorbe surges, so I guess it can be a problem, but seems unlikly
09:45 PM Tom_L: haven't looked at the actual tank so who knows, that's just the outter wrapper
09:45 PM hazzy-m: yeah, be intersteing to see how the tank actually failed
09:46 PM Tom_L: i'm waiting to be sure the ins doesn't want it before i look
09:47 PM hazzy-m: very good idea, they might want to look for bullet holes lol
09:47 PM _unreal_: hazzy-m, thats for water hammer
09:47 PM _unreal_: has far FAR more to do with running the water and sutting the valve off fast
09:48 PM _unreal_: you have a lot of water weight moving fast that acts like a hammer
09:48 PM Tom_L: they have shock absorbers for that
09:48 PM hazzy-m: _unreal_: yes, but the watter hammer supressors are usualy much smaller and at the appliance end of the line
09:49 PM Tom_L: wasn't due to that since everybody was asleep
09:49 PM hazzy-m: in watter hammer the pressure spike is at the valve, not up stream like were the heater would be
09:52 PM hazzy-m: ah, they are expansion tanks to absorbe the exess watter as it expands due to temp rises, that makes sense
09:52 PM Tom_L: kinda like a well tank?
09:52 PM Tom_L: with a bladder inside
09:53 PM hazzy-m: yeah, I guess so, they look very similar
09:53 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20190720_214449.jpg
09:53 PM skunkworks: rigid tapped at 2000 rpm :)
09:54 PM hazzy-m: skunkworks: Nice!!
09:54 PM hazzy-m: STMBL?
09:54 PM skunkworks: yes
09:54 PM _unreal_: tapped at 2k rpm?
09:54 PM skunkworks: yes
09:54 PM hazzy-m: I really need to get mine set up so I can play with them
09:54 PM Tom_L: nice
09:55 PM skunkworks: I have a video but I need to splice some footage together..
09:55 PM _unreal_: What bit are you using for tapping?
09:56 PM _unreal_: or are you using a TAP to do that?
09:56 PM Tom_L: a tap
09:56 PM Tom_L: that's the point of rigid tapping
09:56 PM _unreal_: 2k rpm would thread that in the blink of an EYE
09:56 PM skunkworks: something I found in the tap drawer.. :)
09:57 PM skunkworks: shavings go out the bottom
09:57 PM skunkworks: _unreal_: this is the same tap - just not as thick materail
09:58 PM skunkworks: https://www.youtube.com/watch?v=F7QulGiMt20
09:58 PM skunkworks: yes fast
09:58 PM hazzy-m: yikes!
09:58 PM skunkworks: 750w spindle...
09:59 PM Tom_L: sam, what cad did you use on that?
09:59 PM skunkworks: samcad
09:59 PM hazzy-m: that is impressive
09:59 PM Tom_L: i noticed there were 2 z return levels
09:59 PM Tom_L: mine does that sometimes
09:59 PM Tom_L: z return and z clear
10:00 PM skunkworks: Tom_L: that is a linuxcnc artifact.. when it extracts - it keeps moving z up until the spindle reverses.. then moves back down to z clear
10:00 PM Tom_L: oh yeah that makes sense
10:01 PM hazzy-m: I guess then it also has moved up enough that it can get back up to speed before reaching the z-clear again
10:01 PM Tom_L: no, it will start threading at any speed
10:01 PM Tom_L: the axis and spindle are in synch
10:02 PM hazzy-m: has anybody played with Rene's fast retract threading cycle?
10:02 PM Tom_L: not me
10:02 PM skunkworks: hazzy-m: hmm forgot about that... I should try that.
10:02 PM Tom_L: is that for a lathe or mill?
10:02 PM skunkworks: retract at 4000rpm ;)
10:02 PM skunkworks: it is for rigid tapping
10:02 PM Tom_L: hmm
10:02 PM hazzy-m: Yes, then you'd be hauling!
10:03 PM skunkworks: I would have to do the math for z...
10:03 PM skunkworks: I don't remember what my max is - maybe 150ipm//
10:03 PM skunkworks: so far the machine hasn't skipped a beat
10:03 PM Tom_L: i try to keep mine well under the limits
10:04 PM skunkworks: I added backlash comp for x and y - see how that goes
10:04 PM skunkworks: so far probing is now right on.
10:04 PM skunkworks: _unreal_: http://electronicsam.com/images/greenmachine/IMG_20190720_215120.jpg
10:04 PM Tom_L: i'm not too fond of that because it happens at the beginning of the cut and sometimes can gouge the material
10:05 PM Tom_L: i haven't added any to mine yet
10:05 PM Tom_L: i probably should check it since it's run a while
10:05 PM skunkworks: I should just get some better ballscrews.. some day
10:06 PM skunkworks: hazzy-m: did you see the 'encoder'?
10:06 PM hazzy-m: skunkworks: no
10:06 PM skunkworks: https://www.youtube.com/watch?v=QY_vmW1djao
10:07 PM hazzy-m: I'm behind on watching your videos ...
10:07 PM skunkworks: Thats ok...
10:07 PM -!- #linuxcnc mode set to +v by ChanServ
10:09 PM skunkworks: seb_kuzminsky: !
10:10 PM hazzy-m: skunkworks: very nice! I need to do something similar to that on the boss, using the back gear gear ...
10:11 PM Tom_L: ok gnite everyone
10:11 PM hazzy-m: gn8
10:12 PM hazzy-m: skunkworks: which gear tooth sensors did you use?
10:12 PM skunkworks: umm
10:14 PM seb_kuzminsky: skunkworks: i'm back after a brief blackout
10:14 PM skunkworks: Heh - ok. Pedal bike generator?
10:15 PM hazzy-m: these? https://www.allegromicro.com/en/Products/Sense/Magnetic-Speed/Transmission-Sensor-ICs/ATS667.aspx
10:15 PM hazzy-m: opps, I should have read the description in the vides lol
10:19 PM skunkworks: hazzy-m: umm I don't know.. I don't have the invoice here from digikey
10:20 PM skunkworks: hazzy-m: yes - I am pretty sure it is a 667
10:20 PM skunkworks: biab
10:20 PM hazzy-m: skunkworks: you put it in the video description!
10:29 PM * hazzy-m drifts off to sleep
10:46 PM skunkworks: heh
10:46 PM skunkworks: Right - that's what I did ;)
11:19 PM XXCoder: pink_vampire: lol know whats funny?
11:19 PM XXCoder: my switch died short time after me talking about how reliable irc is!
11:19 PM XXCoder: im using wireless now
11:20 PM pink_vampire: you see I told you
11:20 PM XXCoder: lol
11:20 PM XXCoder: it sucks, we need larger than normal switch
11:21 PM pink_vampire: I solder one more pair
11:21 PM XXCoder: so we cant just go to store and buy one
11:21 PM XXCoder: 16 port switch
11:21 PM XXCoder: 16 port isnt enough we need 24
11:21 PM pink_vampire: I have one I think there's like 32 or 24 something really big and it is 1GB
11:22 PM XXCoder: 1 gbps switch eh
11:22 PM XXCoder: pretty decent
11:22 PM pink_vampire: I know, you got used to fibers so fast
11:22 PM XXCoder: heh no fiberglass connection here
11:23 PM pink_vampire: it was a defective unit and I just replace some parts in it and it was back to normal
11:24 PM XXCoder: wow wish i can do that
11:24 PM pink_vampire: lol I need to call my internet company and ask for composite internet connection
11:24 PM XXCoder: switch here seem ti be fried
11:25 PM skunkworks: Instead of rgb?
11:25 PM pink_vampire: it was pretty simple some capacitors and stuff like that,I did it years ago
11:26 PM pink_vampire: ti?
11:32 PM pink_vampire: he is gone
