12:22 AM JesseG: Got my "close loop steppers" off of ebay today :D. They have the CL57T controller. There's a certain speed where the motor resonates LOL
12:27 AM JesseG: Supposed to not have any hunting LOL
12:27 AM JesseG: and it's also supposed to have following error support...
12:27 AM JesseG: but if I stall it it just keeps trying to catch up -but I only stalled it like over half a turn..
12:49 AM jesseg: teehee...
12:56 AM jymmmm: 152mm gun, gotta love it... https://youtu.be/CPxmGrgVfeY?t=623
01:12 AM Loetmichel: mornin'
01:12 AM jesseg: Good morning
01:16 AM Deejay: moin
01:18 AM Loetmichel: Jymmm: 152mm? sounds like Leopart/abrams
01:18 AM Loetmichel: leopard
01:44 AM jymmmm: Loetmichel: watch the video, it's alredy cued
02:15 AM Loetmichel: Jymmm: i have
02:16 AM Loetmichel: it was just that 152mm automatically links to the abrams/leopard cannon
02:16 AM Loetmichel: in my brain
02:18 AM * Loetmichel has to do a lot of 3d-model-> milling files today and then execute them and see if that all fits like planned. wish me luck... the "perks" of prototyping :-)
04:13 AM Loetmichel: Oh man, coworkers sometimes. $me on the way to the loo, Engineer cuts in and talks 10 minutes about some irrelevant stuff... I am already hopping from one foot to the other... "Hey, Peter, if i dont go peeing NOW you will have to clean up the mess i will make!". him: "Oh, didnt notice!" :-(
05:26 AM jthornton: morning
05:27 AM XXCoder: hey
05:28 AM XXCoder: Loetmichel: expect some design that allows you to pee while staying there chatting with enginner by that engineer soon ;)
05:28 AM Loetmichel: XXCoder: probably ;)
05:30 AM XXCoder: man work wasnt fun for me though
05:30 AM XXCoder: i ran very hard hardened steel parts
05:30 AM XXCoder: so I constantly check tools and change em
05:30 AM XXCoder: i lost quite a lot of productivity due to that
06:23 AM jthornton: almost done with the windows remodeling https://gnipsel.com/images/chickens/12x16-coop/Windows/
06:25 AM XXCoder: we finally finished restroom downstairs
06:25 AM XXCoder: its 95% done or so
06:25 AM XXCoder: looks nice
06:25 AM jthornton: I have to make 4 more pieces of trim for the east window and I'm done with the inside
06:26 AM jthornton: thanks
06:26 AM XXCoder: welcome
06:26 AM XXCoder: whats left is stairs and landing area heh then downstairs is finally done after over a year
06:29 AM XXCoder: thinking about painting upstairs restroom too
06:29 AM XXCoder: paint get chipped if i glance at it lol
06:29 AM XXCoder: super cheap paint
06:29 AM jthornton: wow that's cheap paint
06:30 AM XXCoder: yep. shitty home improvemenbt
06:30 AM XXCoder: downstairs was destoyed coupel months after we moved in because basement leaks water
06:30 AM XXCoder: it doesnt anymore due to sump pump but it was bad year
06:30 AM jthornton: gotta cover my tomato plants for tonight severe thunderstorms then low of 48°F
06:31 AM jthornton: that sucked
06:32 AM XXCoder: one postive out of that shitshow is that house is fully wired for cat6 and also downstairs now has very good isulation
06:32 AM jthornton: nice
06:33 AM XXCoder: upstairs not yet lol but we evenually plan to completely replace shitty outside walls
06:33 AM XXCoder: 1940s planks covered in 1980s alum sidings
06:34 AM jthornton: sunrise here time to let the hens out so they can chase bugs
06:34 AM XXCoder: as well as also rip out outside walls and put in insulation then new walls then new sidings
06:35 AM XXCoder: off to bed laters
06:41 AM jymmmm: jthornton: Isn't that automated now?
06:42 AM jthornton: not letting them out of the chicken run, I survey the chicken yard then let them out at sunrise
06:43 AM jthornton: the door from where they roost and the lights are automagic
06:44 AM jymmmm: jthornton: Ah, ok. When are you installing the surround sound and big screen?
06:44 AM jthornton: next week
06:44 AM jymmmm: jthornton: Cool. Why the mesh on the poly windows?
06:45 AM jthornton: what poly?
06:46 AM jymmmm: polycarb, I thought I saw the reflection, so that's just pure mesh not poly or glass?
06:46 AM jthornton: aluminum screen with hardware cloth over that
06:47 AM jymmmm: so nothing to keep heat in/water out?
06:47 AM jthornton: roof keeps water out, who needs heat when it's hot outside
06:48 AM jymmmm: but it snows in your area doens't it?
06:48 AM jthornton: west side will have a lean too
06:48 AM jthornton: sometimes, chickens don't need heat they are self insulated
06:49 AM jthornton: what is important is draft free ventilation in the winter
06:49 AM jymmmm: ah ok.
06:53 AM jthornton: https://gnipsel.com/images/chickens/12x16-coop/louvers/
06:57 AM jymmmm: WOW, are you thinking about moving in by chance? lol
06:58 AM jymmmm: jthornton: nice job on the louvers btw
07:01 AM jthornton: thanks, they were fun to figure out
07:02 AM jymmmm: Yeah, I bet =)
07:03 AM jthornton: https://gnipsel.com/images/chickens/12x16-coop/wall/
07:07 AM jymmmm: When I saw the first pic I was gonna ask how did you connect the frames together, then I saw the pocket screws =) But on the last pic, the door/wall is inside another building???
07:14 AM jthornton: https://gnipsel.com/images/chickens/12x16-coop/wall/door05.jpg
07:14 AM jthornton: that is installed in the coop dividing wall
07:15 AM jthornton: https://gnipsel.com/images/chickens/12x16-coop/wall/door04.jpg
07:16 AM jthornton: view from the outside of the coop which is inside a larger shed
07:16 AM JavaBean|new is now known as JavaBean
07:21 AM Tom_L: morning
07:22 AM jymmmm: jthornton: ah ok =)
07:22 AM jymmmm: Tom_L good morning =)
07:24 AM Tom_L: mmm, looks like the router needs a kick in the pants... brb
09:05 AM jesseg: hey who here was it that is using Chinesium hybrid closed loop steppers?
10:28 AM The_Ball: jesseg, not using it yet, but I have one to play with
10:31 AM skunkworks: The_Ball: did you see.. https://www.youtube.com/watch?v=C0Wz8vnFAQU
10:33 AM The_Ball: oh wow, that's seriously cool
10:33 AM The_Ball: skunkworks, how are you holding up? I hear you guys are getting hit pretty bad with the virus
10:35 AM -!- #linuxcnc mode set to +v by ChanServ
10:39 AM skunkworks: we are in the midwest. hasn't hit this area yet. Mostly staying home.
10:39 AM skunkworks: The_Ball: how about you guys?
10:39 AM cradek: but you're getting hit pretty bad with the republicans
10:39 AM skunkworks: No comment.
10:39 AM cradek: sorry
10:39 AM The_Ball: We're doing well here in Norway and in Australia so far
10:39 AM skunkworks: the state supreme court voted against postponing voting... But voted remotely..
10:47 AM methods_: sounds legit
10:49 AM The_Ball: skunkworks, samcoinc has been doing a lot of cool stuff
10:59 AM skunkworks: The_Ball: I try to keep busy :)
11:02 AM The_Ball: oh, that's your account? I thought that were two different people
11:10 AM The_Ball: skunkworks, so you've built stmbl, been on my bucket list for a long time. Is that controlling your servo spindle?
11:12 AM Loetmichel: *giggle* Never thought the old beater still has it in it... I accidentally just painted two black upside down "??" on the tarmac while coernering onto the speedway... $me pressed the "DSC" button afterwards to get rid of the "DSC off" led in the dash ;)
11:16 AM skunkworks: The_Ball: yes - but I am not using it as a 'servo'
11:30 AM The_Ball: Nice, I've been chasing the IRAM for a while, need to replace the horribly noisy servo amplifiers in the big iron
11:37 AM Tom_shop is now known as Tom_L
11:40 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube2.jpg
11:40 AM Tom_L: gonna make one of those for something to do
11:57 AM Deejay: re
12:06 PM Loetmichel: Tom_L: that looks like a variant of the classic "turning a cube" Lathe machinist apprentice part
12:44 PM Tom_L: Loetmichel, yeah similar. the kid made one in his class and next is the turners cube. i figured it would be something to do
12:44 PM Tom_L: but physical class is suspended for now
12:51 PM skunkworks: cool
12:52 PM Tom_L: he got his turners block all squared up and class cancelled :(
12:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube1.jpg
12:53 PM Tom_L: i did a small one long time ago that turned out fair
12:56 PM skunkworks: http://electronicsam.com/images/woodcube.jpg
12:57 PM Noxz: I tried to look for any opensource android DRO projects, but appears the main one coming up (touchdro) is closed source (for the android end).. any known open android ones out there?
12:58 PM Noxz: an alternative is to run proper linux
01:00 PM Loetmichel: yeah, Tom_L, thats what i had in mind. good to know its called a "turners cube"
01:01 PM Loetmichel: skunkworks: what wood?
01:01 PM Loetmichel: looks a bit like "hartgewebe"
01:02 PM FinboySlick: Anyone played with one of those yet? If it can hit good latency target it looks like an amazing LinuxCNC board: https://www.youtube.com/watch?v=WzEf_K5POio
01:02 PM Loetmichel: (resin laminated fabric)
01:02 PM Loetmichel: i think you guys over there call it "phenolic"
01:04 PM FinboySlick: Loetmichel: And you guys call it dasdingausharzundleinwand ?
01:09 PM Loetmichel: FinboySlick: we call it "Hartgewebe"
01:09 PM Loetmichel: or "harpapier" if its made of paper and phenolic resin instead of canvas
01:09 PM Loetmichel: Hartpapier
01:10 PM Loetmichel: lierally "hard fabric" and "hard paper"
01:10 PM FinboySlick: I just love how you guys can glue up words together and form new ones.
01:11 PM Loetmichel: FinboySlick: Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz
01:11 PM Loetmichel: yes, thats a real law ;)
01:12 PM Loetmichel: at least i once was one ;)
01:13 PM Loetmichel: FinboySlick: https://en.wikipedia.org/wiki/Rinderkennzeichnungs-_und_Rindfleischetikettierungs%C3%BCberwachungsaufgaben%C3%BCbertragungsgesetz
01:16 PM skunkworks: Loetmichel: I think it was black walnut
01:18 PM Loetmichel: skunkworks: ah, thanks
01:18 PM Loetmichel: really looks a bit like that phenolic canvas stuff
01:20 PM Loetmichel: https://seglerbedarf.de/media/images/org/lt65931040.jpg
01:20 PM Loetmichel: ah, "tufnol" is another name for it
01:21 PM Loetmichel: if you cut that at the right angle it has nearly the same structure as your square
01:22 PM Tom_L: Loetmichel, turners cube since it can be done on a lathe
01:22 PM CaptHindsight: Noxz: DRO = digital read out?
01:22 PM Tom_L: the first one can't
01:23 PM Tom_L: nice one skunkworks
01:24 PM Noxz: CaptHindsight, Yes
01:25 PM Noxz: I would like to import values from a toolmaker's (measuring) microscope, and want a method of "autmatically" storing the values into a database without further processing, and figure an android tablet is a very simple and cheap platform for a DRO capable of a bit more, just no open source projects that I could find
01:25 PM Noxz: wow, please excuse the stuck space bar
01:26 PM Noxz: umm, nevermind, my irc client went weird
01:28 PM Tom_L: Noxz, you see this one: https://hackaday.com/2017/05/26/making-an-inexpensive-dro/
01:28 PM Tom_L: dunno if it OS or not
01:29 PM Noxz: I would be more interested in a tablet format more than anything
01:30 PM Tom_L: https://hackaday.com/2012/09/24/adding-digital-readout-to-a-non-cnc-mill/
01:30 PM Noxz: Yuriy is the TouchDRO guy, and afaik the android source is NOT open
01:30 PM Noxz: he opened the sensor bluetooth modules and whatnot
01:30 PM Tom_L: ahh
01:31 PM Noxz: LittleMachineShop sells a tablet loaded with it - and specifies a 'fully licensed' or similar version - whcih means they likely asked him for some alterations etc
01:31 PM FinboySlick: Noxz: What does the microscope look like?
01:32 PM Noxz: it's a vintage Leitz UWM, Digital, with Heidenhain LID 310 scales, 10 micron grating and sinusoidal Vpp - wo I will interpolate and bluetooth those out - preferbly to an android display
01:33 PM Noxz: so, jsut two axis, but I have further plans of why I wanted opensource
01:33 PM FinboySlick: Noxz: 'easy' android development is to make a web app that is compatible with the android web browser.
01:33 PM Noxz: for instance, if each part was on a pallet with a barcode I could use ZXing lib to rea those from the tablet camera (I have done this from a webcam on a little linux ARM device)
01:34 PM Noxz: yup - I thought about going the web route as well
01:34 PM FinboySlick: Noxz: It could be simple enough to fit in an arduino.
01:34 PM Noxz: but then I still need a screen + inpout interface
01:34 PM FinboySlick: Well, you can use any android browser for that.
01:34 PM Noxz: so why not an inexpensive android tablet? sub $100 nowadays
01:35 PM FinboySlick: Well, the point I'm making is make it wif+tcp instead of bluetooth.
01:36 PM FinboySlick: Then you can do most of the heavy lifting in javascript on the tablet (or any browser).
01:36 PM Noxz: the only reason I would do BLE is because I have a devkit for a certain chip - but have also looked at the ESP32
01:36 PM Noxz: I think a browser based one may be the way to go in the end, too
01:37 PM Noxz: the main t hing I want to do is easily track each (barcoded) part, so I can maybe detect when/where things go awry - and it's certainly cheaper than any CMM
01:38 PM Tom_L: just so the tools don't need certification...
01:39 PM Noxz: but, CMM is essentially the goal
01:40 PM Tom_L: my bud got the table from his first cmm back from the guys that purchased his business. they'd left it out in the rain
01:40 PM Tom_L: still a good granite plate but that's about it
01:41 PM Noxz: I have a 600x900x~75mm surface plate on a proper 3 point stand
01:41 PM Noxz: mostly been covered as I work on tooling up
01:47 PM Noxz: I think the web browser makes a bit of sense, actually.. because as I am doing CAD/CAM I can use the interface on an actual computer to create templates of positions/values to check and verify... Oh, I also heard from [professional] machinists that most CMM software is terrible, so I haven't been driven enough to pursue looking at that solution
01:48 PM FinboySlick: The tool you sell once. Software is what you use to keep people locked in.
01:48 PM Noxz: the barcode reading aspect through the android camera may be a miss w/ the browser? I'd have to look into that further
01:49 PM FinboySlick: Well, if the camera is good enough and you can use OpenCV, you won't need the microscope at all ;)
01:50 PM Noxz: this is sort of the reason I wanted an already existing open source android project
02:04 PM skunkworks: Tom_L: never actaully finished one. That was me trying to play with o-words when I had to add them manually to emc2
02:22 PM Noxz: a user elsewhere gave the advice of using an older DRO with serial output that can then be read and pushed into a database (for part/feature tracking).. decent option
02:26 PM Rab: Noxz, have you investigated this bitbucket repo? https://www.yuriystoys.com/2012/12/source-code-for-dro.html
02:26 PM Rab: Post is from 2012, no idea if there's still anything there. Looks like a bitbucket account is needed to see it, so I can't check.
02:27 PM Rab: Hmm, looks like it's gone according to later comments.
02:28 PM Noxz: oh, doh
02:28 PM Noxz: would have been a good find though
03:45 PM Deejay: gn8
04:22 PM Tom_L: 88°F
04:23 PM Tom_L: so much for a mild spring
05:10 PM andypugh: It’s like a switch was thrown and the weather said “winter off / summer on”
05:12 PM andypugh: Though in the UK today was _lovely_
05:12 PM andypugh: At least in my part of Essex.
05:12 PM andypugh: I tidied my workshop
05:13 PM andypugh: And then had a really fun machining job. Converting a big R8 fly-cutter to BT30 for my mill.
05:14 PM andypugh: The bottom part of R8 is the same as BT / CAT / INT 30, so this isn’t so hard in some ways. But it was a workholding challenge.
05:16 PM andypugh: This is close enough to the same design for discussion:
05:16 PM andypugh: https://www.amazon.co.uk/Cutter-Shank-Bridgeport-Milling-Machine/dp/B076HS45Y9
05:16 PM andypugh: Except mine is 4” / 101mm dia and takes a 16mm cutter.
05:17 PM andypugh: Step 1 was to hold the parallel shank in the lathe chuck and add a cenre drilled hole in the bottom of the tool slot.
05:18 PM andypugh: Then I hacksawed off the shank to approx lenght
05:19 PM andypugh: Luckily my version had a small flat section on the low part of the sloping face, so I could clamp it on the mill table and drill another centre hole in the cut-off end.
05:20 PM andypugh: Then I machined between centres to make the new taper cone.
05:20 PM andypugh: In a bit of unexpected luck the 16mm slot would fit round the jaws of a 3-jaw chuck so no drive dog was needed.
05:21 PM andypugh: Then it got more trickier.
05:24 PM andypugh: You have to be braver than me to drill axial holes between centres :-)
05:49 PM flyback: is elmo40 ok?
05:49 PM flyback: not seen him in weeks
05:51 PM Loetmichel: i have seen him a few days ago
05:51 PM Loetmichel: pretty sure
05:51 PM Loetmichel: cant say if here or in some other channel though
05:52 PM Rab: Last comment on March 11, last part on March 23, client pi____ last part on March 24.
05:53 PM andypugh: So, if anyone is reading my stuff, the next puzzle was drilling and tapping the hole in the end for the pull-stud.
05:54 PM andypugh: Luckily I have previously made a fitting for my lathe spindle that take BT30 (for using milling holders, and for making milling holders)
05:56 PM andypugh: So, to drill the hole, the solution I came up with was to clamp a lump of aluminium in the tool slot and face that off flat with the tailstock pushing the fly cutter into the BT30 socket on the lathe. This gave me a flat surface to clamp down to the mill table, where I could drill, tap and bore the pull-stud thread and register,
05:56 PM andypugh: (ie, the tool slot for the fly-cutting tool)
05:57 PM Tom_L: all turned out nice n centered?
05:57 PM andypugh: I don’t knw…
05:57 PM andypugh: You see, I have no idea how to do the dog slots.
05:58 PM Tom_L: is the tool fairly hardened?
05:58 PM Tom_L: surface hard
05:58 PM andypugh: Indeed to cut square-edged holes right next to the BT30 taper.
05:59 PM sync: machine a female taper in a piece of square stock and mount it in there
05:59 PM andypugh: No, luckily it is fairly soft.
05:59 PM andypugh: sync: The problem is that the taper shank is now in the way of all my tooling.
06:00 PM andypugh: Though perhaps skunkworks has shown the way!
06:00 PM andypugh: I could make round holes then square them out with his magic boring technique,
06:01 PM andypugh: Hmm, that might be fun.
06:01 PM Tom_L: if you trust the accuracy
06:01 PM andypugh: It’s not so critical for the drive dogs.
06:01 PM Tom_L: that's true
06:02 PM andypugh: That’s actually a really interesting idea.
06:04 PM Tom_L: how do you go about setting the tool?
06:04 PM Tom_L: center the tip on X Y 0?
06:07 PM andypugh: Bore a test hole, I suppise, and measure.
06:14 PM BitEvil is now known as SpeedEvil
06:18 PM flyback is now known as fishhead
06:18 PM fishhead is now known as i8086
06:19 PM i8086 is now known as flyback
06:20 PM sync: get a long weldon holder andypugh?
06:20 PM sync: or make one?
06:20 PM andypugh: Give me a few minutes to make a model….
06:24 PM _unreal_: hi

06:27 PM _unreal_: try teling that to ve7it
06:27 PM _unreal_: I'm building/using dont know much about the design
06:27 PM rue_mohr: I had LOTS of problems with PICs locking up in high EMI environments
06:27 PM _unreal_: and software, ve7it designed and programmed it
06:28 PM _unreal_: any idea what the source issue was? ASIDE from emi
06:28 PM _unreal_: All of my wiring is twisted and or beaded
06:28 PM CaptHindsight: Tom_L: 80F yesterday, 33F tonight, you don't know what to wear from when you leave to you return
06:28 PM rue_mohr: mircochips products just do NOT take well to noise
06:28 PM rue_mohr: they latch up
06:28 PM _unreal_: CaptHindsight, lol
06:29 PM _unreal_: rue_mohr, as i said everything is going to have protection on it
06:29 PM _unreal_: I'm also mounting these inside a metal shell
06:29 PM CaptHindsight: was 70F and humid just hours ago
06:29 PM _unreal_: CaptHindsight, was almost 90 today expect 70's for the low ;)
06:29 PM _unreal_: as always
06:30 PM CaptHindsight: volatile past few days
06:30 PM rue_mohr: I like how we all have a circa 1980 website tucked away somewhere
06:30 PM _unreal_: ?
06:30 PM rue_mohr: :)
06:30 PM CaptHindsight: the textured paper background
06:31 PM _unreal_: ?
06:31 PM _unreal_: I'm lost
06:31 PM rue_mohr: and the hand written code
06:31 PM CaptHindsight: http://ve7it.cowlug.org/dspic-servo.html
06:31 PM rue_mohr: and the decorations
06:31 PM _unreal_: thats not 80's thats 2k's
06:31 PM rue_mohr: http://ruemohr.org/
06:31 PM rue_mohr: mine isn't any better
06:32 PM _unreal_: I'd have to archive.org to show you mind AND YES the same
06:32 PM _unreal_: rue_mohr, heheh
06:32 PM _unreal_: remember the net apliences days?
06:32 PM _unreal_: iopener stuff like that
06:33 PM rue_mohr: it kinda flew by for me
06:33 PM _unreal_: regardless
06:33 PM rue_mohr: I was always serving off spare pc's
06:33 PM _unreal_: I have iopeners and other toys from them
06:33 PM _unreal_: that time
06:33 PM _unreal_: anyways
06:33 PM rue_mohr: :)
06:33 PM _unreal_: I have an eznet 200
06:33 PM _unreal_: 2 of them
06:33 PM _unreal_: geode cpu, blaa blaa blaa very hackable
06:34 PM _unreal_: last year I finally cracked part of that annoyed me since 2000 when I got it
06:34 PM _unreal_: 19 years
06:34 PM _unreal_: and I figured out how to get quake and doom2 and stuff like that to work on it
06:34 PM rue_mohr: :)
06:35 PM _unreal_: was a stupid few autoexec/config.sys entries and they suddenly worked
06:35 PM andypugh: I have the first website I hand coded in 1992 still up.
06:35 PM _unreal_: interesting
06:36 PM andypugh: I don’t think that any 1980s web sites exist.
06:36 PM rue_mohr: actaully thats a good point
06:36 PM rue_mohr: might have been a bit far back there
06:37 PM andypugh: The firs browser was written in 1991
06:37 PM SpeedEvil: gopher
06:37 PM SpeedEvil: sorta
06:37 PM CaptHindsight: most sites written in the 90's looked similar
06:37 PM andypugh: 1992 was when we got an email at work “a new thing has been invented called the world wide web, here are the seven sites that currently exist”
06:38 PM CaptHindsight: https://www.digitalspy.com/tech/a797267/11-forgotten-websites-that-used-to-rule-the-internet-from-aol-to-myspace/
06:38 PM andypugh: (I only remember 3 of the seven now, CERN, CIA World Factbook, Vatican Library)
06:39 PM _unreal_: I loved napster
06:40 PM andypugh: Yeah, but those came along lots later.
06:40 PM Loetmichel: quite a bit later i may add ;)
06:40 PM andypugh: I was working at a University at the time, before the general public arrived.
06:40 PM p0g0: archie, jughead, & gopher...
06:41 PM andypugh: There are still a couple of gopher servers running.
06:41 PM _unreal_: I really miss the old gaming sites
06:41 PM andypugh: I think that some of the current browsers still accept gopher://
06:42 PM CaptHindsight: newgrounds to test flash
06:43 PM CaptHindsight: and 100% flash websites, how awful
06:44 PM andypugh: 395 Gopher servers running: https://en.wikipedia.org/wiki/Gopher_(protocol)
06:45 PM andypugh: (dropped to 144, now on the way up again.)
06:46 PM _unreal_: zone.com mplayer.net gamespy heat.net
06:52 PM rue_mohr: ve7it, nice site!
06:52 PM rue_mohr: my in-circuit cap tester needs a scope :)
06:55 PM flyback: I rememeber newgrounds
06:55 PM flyback: yeah they got screwed when adobe abandoned shockwave and now flash soon
06:55 PM _unreal_: how about gizmozone.com
06:57 PM _unreal_: https://web.archive.org/web/20000304124508/http://www.heat.net/
06:58 PM _unreal_: I still have a free shirt from them and DOG tags
06:58 PM _unreal_: in mint condition
06:58 PM _unreal_: and other stuff
06:59 PM _unreal_: SOOOOOOO many hours of gaming
06:59 PM _unreal_: I was in my teens when they first opened
07:03 PM andypugh: sync: https://a360.co/2XrXPuF
07:05 PM andypugh: ^ that’s a 3D model of my fly cutter. The whole thing is a workholding nightmare, and the drive dog holes add another level on top.
07:05 PM andypugh: The easu answer is to go in from the side with a big cutter.
07:06 PM _unreal_: andypugh, What is the diam?
07:06 PM andypugh: Going in from the top is pretty much impossible with anything small enough to make reasonable corners.
07:06 PM andypugh: 100mm is the biggest dia
07:06 PM _unreal_: ahh
07:07 PM andypugh: But the polygonal boring thing really might work.
07:07 PM _unreal_: andypugh, I didnt know you used fusion
07:07 PM _unreal_: ! infact I think I remember you POO POO'ing fusion360 once
07:08 PM andypugh: I couldn’t figure out how to make my Inventor license work any more, and Fusion means I can avoid using a VM.
07:09 PM andypugh: I don’t think I poo-pooed it. I might have said that Inventor was better. Bit the CAM in Fusion is rather ahead of the (free layer) Inventor CAM
07:16 PM flyback is now known as carlsagan
07:16 PM carlsagan is now known as flyback
07:28 PM sync: yeah I guess a long tapered extension could work andypugh
07:31 PM andypugh: I am more interested in the technically interesting solution.
07:34 PM _unreal_: :)
07:34 PM _unreal_: GOD this is daunting
07:35 PM _unreal_: I'm looking at the 4th/final pcb to build for this project of mine
07:35 PM _unreal_: its not that I want to do it its that I REALLY dont want to soldering a 4th one together
07:35 PM _unreal_: build time is like 5 hours
07:36 PM _unreal_: cnc mill it, cnc drill it, manually drill some holes, mount all the though hole parts, then the SMD parts
07:36 PM _unreal_: ARG
07:36 PM _unreal_: I'm already on my 3rd corona
07:37 PM _unreal_: corona WITH LIME :)
07:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube1.jpg
07:39 PM Tom_L: boredom block
07:40 PM _unreal_: lol
07:40 PM _unreal_: boredem block
07:41 PM _unreal_: I only wish I could be bored
07:41 PM _unreal_: my industry can not be shut down
07:42 PM _unreal_: we work on military boats, police boats, coast guard ETC..... boats plus the luxury million dollar boats
07:42 PM Tom_L: you keep the drugs you find in em?
07:43 PM _unreal_: ! dont people just dont know how to SHUT UP
07:43 PM _unreal_: ;)
07:49 PM JavaBean|new is now known as JavaBean
07:51 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200408_194958.jpg
07:51 PM skunkworks: doesn't fit.. ran out of time ;)
07:53 PM skunkworks: andypugh: ^
07:53 PM skunkworks: I really now need to fit a better encoder...
07:54 PM _unreal_: skunkworks, what kind of encoder do you need?
07:55 PM skunkworks: something with a lot more than 152 counts per rev
07:55 PM _unreal_: ahh something that is not tooth count
07:56 PM _unreal_: !
07:56 PM skunkworks: real encoder.. ;)
07:56 PM _unreal_: skunkworks, you may as well mount a second pulley and direct drive an encoder
07:56 PM _unreal_: I'd suggest a 1:1 ratio if you can
07:57 PM skunkworks: sure - quite a few ways to do it. Just didn't think I would need a higher count encoder.
07:57 PM _unreal_: ?
07:57 PM Tom_L: pretty soon you'll be making your own endmills :)
07:57 PM _unreal_: skunkworks, a high quality CHEAP
07:58 PM Tom_L: i got mine off some old medical equipment
07:58 PM _unreal_: timing belt driven encoder is going to set you back $16 and still give you 400ppr
07:58 PM _unreal_: running on the cheap
07:58 PM Tom_L: not made for it but it's been working quite well for a long time
07:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/spindle_enc2.jpg
07:59 PM _unreal_: skunkworks, regardless a higher res encoder will giveyou smoother results/movments on your xy
08:00 PM _unreal_: Tom_L, ;) how dare you steal my descritpion
08:01 PM _unreal_: Tom_L, just ordered this. big upgrade over my current spindle on my home machine https://www.aliexpress.com/item/4000801582283.html?spm=a2g0s.9042311.0.0.50cd4c4drV2WdF
08:02 PM Tom_L: wow, that's smaller than mine
08:02 PM Tom_L: 300 W?
08:02 PM _unreal_: its much bigge then my current
08:02 PM _unreal_: My current is a brushed 200watt
08:03 PM Tom_L: so 50% increase
08:03 PM _unreal_: Tom_L, https://drive.google.com/open?id=1D-k13xqrv-9Z-6ok8anqo4-VMt7iCLG4
08:03 PM Tom_L: so put that one on your daughters
08:04 PM _unreal_: ! DONT tempt me
08:04 PM _unreal_: ! I should take and post a photo of the progress on the design/build of that one
08:04 PM _unreal_: looks really good. NOT working yet but looks good
08:05 PM _unreal_: I've just not bothered to solder the control wires together and the motor wires etc...
08:05 PM _unreal_: That and I goofed and forgot to write down the pinouts as I was making them.... I have now written them down BUT
08:08 PM _unreal_: OMG that smells so good
08:08 PM _unreal_: cooking boiled dinner
08:14 PM CaptHindsight: hopefully not burgers or cake
08:15 PM _unreal_: ?\
08:15 PM gregcnc: boiled cake...
08:17 PM _unreal_: lol WHO eats this slop
08:17 PM CaptHindsight: just baked a cake here
08:18 PM * _unreal_ is about 1.5 hours away from din
08:18 PM _unreal_: sigh
08:19 PM CaptHindsight: gregcnc: situation intensifies here
08:19 PM _unreal_: ?
08:20 PM gregcnc: was hoping it would be levelling off
08:21 PM CaptHindsight: the models show us levelling in another 1-2 weeks
08:21 PM CaptHindsight: around here
08:22 PM CaptHindsight: gregcnc: pm
08:24 PM CaptHindsight: https://covid19.healthdata.org/united-states-of-america you can chart the predictions based on country and state
08:25 PM _unreal_: less then ideal LOLOLOL https://www.youtube.com/watch?v=R-PdPtqw78k
08:30 PM unterhaus: I just got everything I needed to bake bread today. Yeast was a bit of adventure
08:31 PM CaptHindsight: i cheated and used self rising
08:32 PM gregcnc: we did a couple in the bread maker, used to do it a lot
08:33 PM CaptHindsight: unterhaus: cake or powdered?
08:35 PM jymmmm: CaptHindsight: YAY it'll all be over June 28th =)
08:35 PM CaptHindsight: jymmmm: can't wait to start licking!
08:36 PM unterhaus: I got some yeast from a neighbor from facebook
08:36 PM unterhaus: cnc home made tablesaw. Uses mach https://www.youtube.com/watch?v=Yft8yBKOPAE&feature=youtu.be
08:37 PM BitEvil: I've been wondering abou tthat sort of thing for a while
08:37 PM jymmmm: CaptHindsight: I that was your profession?
08:37 PM BitEvil is now known as SpeedEvil
08:38 PM CaptHindsight: jymmmm: yup official at the post office in the stamp section
08:43 PM sync: skunkworks: oh, did you use your method on the outside?
08:44 PM CaptHindsight: I need one with 6ft wings
08:45 PM CaptHindsight: 99% cutting of plastic sheet
08:45 PM sync: haha seems like it's the same story over the pond unterhaus
08:49 PM CaptHindsight: but I need to rip 8-10ft strips
08:50 PM CaptHindsight: the fence is too wobbly
08:51 PM CaptHindsight: just think how much better that saw could be with LCNC
08:58 PM CaptHindsight: smarter than the average bear https://youtu.be/io9SxQXcYzo?t=89
09:07 PM skunkworks: sync: yes - 'lathe mode'
09:19 PM unterhaus: the control cabinet on that saw would have gotten him pretty far towards the cost of a nice cabinet saw
09:20 PM unterhaus: people have trouble with their cast metal trunnions, hate to think about how long a wood trunnion would last
09:28 PM CaptHindsight: unterhaus: https://i.imgur.com/LOriL1y.png I get these trunnions from an outfit down in tenn
09:29 PM CaptHindsight: they are cast then machined, this one is ~23" wide
09:31 PM CaptHindsight: not perfect, but a good starting point
10:11 PM skunkworks: CaptHindsight: how expensive?
10:14 PM CaptHindsight: skunkworks: https://www.ebay.com/usr/stan.mms?_trksid=p2047675.l2559
10:14 PM CaptHindsight: just the trunnion without the motor or bearing and stand on the left is ~$1500
10:15 PM CaptHindsight: https://www.trunniontable.com/
10:20 PM Rab: CaptHindsight, cast iron?
10:20 PM CaptHindsight: Rab: yes
10:20 PM fdarling: to change the font size in LinuxCNC (Axis), do I really have to edit the Python sourcecode?: http://linuxcnc.org/docs/2.8/html/gui/axis.html#_change_the_text_font
10:23 PM CaptHindsight: they hold <0.002" between centers over 23"
10:24 PM CaptHindsight: we make them better if we need it
10:25 PM CaptHindsight: that is worst case, they show up under <.001"
10:35 PM Tom_L: fdarling, i don't think axis has changed much from 2.7 to 2.8 has it? the documentation sure has
10:37 PM _unreal_: nothing like picking boiled dinner out of your teeth
10:48 PM _unreal_: oeveryone must be asleep
10:49 PM Tom_L: nope just ignoring you :D
10:49 PM Tom_L: actually i was reading
10:51 PM JavaBean: who are you ignoring?
10:52 PM Tom_L: nobody actually, _unreal_ just felt lonely
10:53 PM * JavaBean cries out, keeps forgetting how much it hurts to put lotion on his hands
10:54 PM _unreal_: it puts the lotion in the basket
10:54 PM Tom_L: it's those cuts you don't feel that concern me
10:54 PM JavaBean: yeah? well those girls weren't dealing with 23% humidity in that hole
