[17:43:57] <XXCoder> hazzy-m: only one actually
[17:44:03] <XXCoder> russia troll is blank pages
[17:44:19] <hazzy-m> yeah, just noticed, strange
[17:44:31] <hazzy-m> there are only two then :)
[17:44:34] <hazzy-m> logs
[17:44:43] <XXCoder> lol
[17:45:53] <hazzy-m> my server was sleeping on the job, just had to give it a good talking to
[17:48:35] <CaptHindsight> Linuxcnc has matured
[17:48:54] <CaptHindsight> most questions are searchable on the forums
[17:49:38] <CaptHindsight> unfortunately many people don't put in the effort to move away from winders
[17:50:09] <CaptHindsight> even the Chinese CNC's feature Mach vs LCNC
[17:50:51] <CaptHindsight> when I was in China there was an influence to write Chinese CNC applications
[17:51:33] <CaptHindsight> i think it was mainly due to the lack of Linux familiarity there
[17:51:56] <CaptHindsight> most had $2 winders ISO's on their computers
[17:52:26] <CaptHindsight> they only saw it as $2 vs free
[17:53:54] <CaptHindsight> https://www.automationtechnologiesinc.com
[17:54:12] <CaptHindsight> https://www.automationtechnologiesinc.com
[17:54:20] <CaptHindsight> or mach3/4 on his site
[17:54:37] <CaptHindsight> he sells the licenses and gets a %
[17:55:11] <CaptHindsight> I've asked him about LCNC and only get a blank stare
[17:55:24] <XXCoder> vcarve isnt that free? or was that different one with same name
[17:55:34] <XXCoder> not surpised no money inn lcnc
[17:55:54] <CaptHindsight> but he was almost jumping up and down about carrying the 3d printers and giving back a few $ to the designers
[17:56:27] <CaptHindsight> Vcarve pro $689
[17:56:45] <CaptHindsight> and so lesser version for $144
[17:56:50] <CaptHindsight> so/some
[17:57:35] <CaptHindsight> looks like 7-8 different versions with different prices

[18:12:15] <BitEvil> CaptHindsight: On the aforementioned topic of diamond infused knives.
[18:12:17] <BitEvil> https://phys.org
[18:12:24] BitEvil is now known as SpeedEvil
[18:12:49] <SpeedEvil> Now, engineers at the UCLA Samueli School of Engineering have developed a way to weld the alloy, known as AA 7075. The solution: infusing titanium carbide nanoparticles—particles so small that they're measured in units equal to one billionth of a meter—into AA 7075 welding wires, which are used as the filler material between the pieces being joined. A paper describing the advance was published in
[18:13:16] <SpeedEvil> https://www.nature.com
[18:13:31] <CaptHindsight> neat
[18:15:00] <SpeedEvil> http://sci-hub.tw 1.7% by volume of 40-60nm TiC
[18:15:35] <SpeedEvil> I would be truly astounded if this couldn't be extended to some other alloys that fail in similar manner.
[18:16:05] <CaptHindsight> have there been any recent patents aps for TiC rod?
[18:16:37] <SpeedEvil> Oooh
[18:16:40] <SpeedEvil> https://www.alibaba.com
[18:16:48] <SpeedEvil> $20-60/kg
[18:17:57] <CaptHindsight> a plasma setup to make particles isn't that complicated
[18:18:09] <CaptHindsight> was just thinking about making one the other day
[18:18:35] <CaptHindsight> but thats already cheap from China
[18:18:36] <SpeedEvil> CaptHindsight: Well, yes. And that might be a reasonable route if you can't cheaply buy it off the shelf for $0 (rounded) per kilo of prodct
[18:19:15] <CaptHindsight> i was thinking about copper
[18:19:21] <CaptHindsight> no copper oxide
[18:19:35] <SpeedEvil> ah
[18:19:40] -!- Roguish has joined #linuxcnc
[18:20:30] <CaptHindsight> packaged in Nitrogen or stabilized in a solvent
[18:21:33] <CaptHindsight> https://xingluchemical.en.alibaba.com
[18:23:14] <SpeedEvil> Oh. For the above diamond/copper I was just thinking molten infiltration
[18:23:53] <SpeedEvil> The nature paper says basically 'we melted aluminium, and flux and powder, and it just works' - then they extruded it.
[18:23:58] <SpeedEvil> (to get the rods)
[18:25:43] <CaptHindsight> yeah, I was thinking about printed vs plated PCB's
[18:25:56] <SpeedEvil> ah
[18:28:27] <CaptHindsight> the rods seem easy to make
[18:29:02] <SpeedEvil> yeah. Molten aluminium + powder + blendtek
[18:29:08] <CaptHindsight> " This method and introduced mechanisms provide an innovative pathway to fabricate filler wires which enable arc welding for other hard to weld material systems and have the potential to improve welding of dissimilar materials."
[18:29:44] <SpeedEvil> CaptHindsight: It doesn't really stop there.
[18:30:06] <SpeedEvil> As it could be quite inexpensive if you put it at the beginning of your average rolling mill/...
[18:30:19] <XXCoder> theres pcb services that you can get 10 for $5
[18:30:21] <SpeedEvil> Or casting.
[18:30:35] <XXCoder> within certain complex level plus size i guess
[18:30:41] <SpeedEvil> For metals that have problems with grain size on welding.
[18:31:00] <SpeedEvil> grain growth in the base metal leading to cracks
[18:32:12] <XXCoder> CaptHindsight: is that breakout board or what
[18:32:27] <XXCoder> also wow so many inputs and some outs
[18:33:26] -!- Tom_L has quit []
[18:33:45] -!- Tom_itx has joined #linuxcnc
[18:33:57] <SpeedEvil> Hmm. Diamond nanopowder is unfortunately 'expensive' at $10/g.
[18:36:32] <CaptHindsight> XXCoder: the goal is to print boards faster and cheaper than plating
[18:37:09] <XXCoder> just directly deposting metal traces eh
[18:37:34] <CaptHindsight> has to be copper
[18:37:59] <SpeedEvil> Silver works too, and a few other metals.
[18:38:14] <CaptHindsight> yes, but the cost is too high
[18:38:40] <XXCoder> how about abusing the inkjet system?
[18:38:42] <SpeedEvil> Silver is $15/oz or so. At 1 oz/sqft, that is not prohibitive.
[18:38:54] <XXCoder> just lay copper powder alloy, then burn it into copper traces
[18:39:26] <CaptHindsight> XXCoder: we have already been doing it for years but
[18:39:36] <CaptHindsight> raw materials and patents have been the issues
[18:39:49] <SpeedEvil> Patents are annoying.
[18:40:05] <SpeedEvil> Some are legit, 99.99% are not.
[18:40:08] <XXCoder> yet something worthy to have otherwise people wont bother to invent
[18:40:17] <XXCoder> but yeah rounded recangle, apple inc
[18:40:25] <XXCoder> THAT is one of unworthy ones.
[18:40:32] <CaptHindsight> system works as planned
[18:40:40] <XXCoder> did you know theres hundreds thousands of patents on phones?
[18:40:54] <SpeedEvil> XXCoder: Sure. But inventions need to be actually hard - on the level of 100* the total effort it would take an average engineer to do a full patent search for an invention.
[18:41:08] <SpeedEvil> XXCoder: Or rather not 100* - but average patents in a product *
[18:41:17] <XXCoder> cull useless patents out and its easier to search
[18:41:36] <SpeedEvil> Or it's not a patent on a technology, it's a tax on engineers developing stuff as normal.
[18:41:38] <CaptHindsight> it's designed to keep YOU from playing
[18:41:58] <gloops> misread that as 'cull useless patients' lol
[18:42:10] <XXCoder> capt what should happen is inventor has exclusive rights for while, then everyone can join in the fun
[18:42:15] <XXCoder> but it doesnt
[18:42:38] <CaptHindsight> ayes, the system has been hijacked
[18:42:39] <XXCoder> lol gloop
[18:42:51] <SpeedEvil> See also copyright 'for a limited period'.
[18:42:59] <XXCoder> mickey mouse finally expired
[18:43:14] <XXCoder> this year is first time usa has copy expirations for 20 years
[18:43:46] <XXCoder> https://www.theguardian.com
[18:44:07] <XXCoder> 1922 is now public
[18:44:08] <SpeedEvil> There is an argument for >15 years. There is no reasonable argument for life+70.
[18:44:36] <CaptHindsight> XXCoder: https://www.nano-di.com
[18:44:41] <XXCoder> SpeedEvil: what I would set is lifetime or 25 years, whichever is longest
[18:44:44] <SpeedEvil> Your average young authors work if published in 1922 would not now expire till 240
[18:44:47] <XXCoder> no more than that
[18:44:49] <SpeedEvil> 2040
[18:45:30] <gloops> i dont know, an inventor might only make one thing in his lifetime that generates any income
[18:45:49] <XXCoder> ie: if published, then die 10 years later, then it gets 25 years from publish date. if author lives more than 25 years afterwards then it expires anyway
[18:46:16] <XXCoder> gloops: inventing and creating is different invention patent lives maybe 7 years depend on counyru
[18:46:23] <XXCoder> supposely anyway
[18:46:45] <CaptHindsight> XXCoder: get some $ and lobby for this change in congress
[18:47:02] <XXCoder> hah good luck getting enough money
[18:47:05] <CaptHindsight> and then get the WTO to follow
[18:47:11] <gloops> i suppose anyway with the pace of technology now, most inventions are superceded pretty quickly, within a decade or so
[18:47:45] <XXCoder> gloops: yeah the rationale of 7 years for patents. but companies is cheating on it
[18:47:59] <XXCoder> so patents is very messy and diffult to figure out.
[18:48:03] <CaptHindsight> https://www.youtube.com
[18:48:07] <XXCoder> hell even patent lawyers have problems.
[18:48:37] <CaptHindsight> XXCoder: Is the camera man sitting on a roller coaster ??
[18:48:49] <XXCoder> CaptHindsight: was that circuit board printer?
[18:48:59] <CaptHindsight> motion sickness warning
[18:49:00] <XXCoder> also, damn bad camerawork, couldnt watch for more than minute
[18:49:01] <CaptHindsight> yes
[18:49:07] <CaptHindsight> yeah awful
[18:49:25] <XXCoder> no shit. im extremely sensive to it when i am even slightly sick, and I am still recovering
[18:50:15] <XXCoder> damn cameraperson trying to make it extreme cool by fancy camera shooting, and it all ends up looking like home video.
[18:52:18] <XXCoder> dont they have ever heard of anti-shake tech? oh its too soon, just onvented 15 years ago or so
[18:52:37] <SpeedEvil> Gimbals are getting nice and inexpensive.
[18:52:54] <XXCoder> unfortunately more and more people just use phone
[18:53:02] <XXCoder> which dont exactly have room for those stuff
[18:53:14] <skunkworks> have 2/3rds of the gantry crane running.. Nice having vfd's running the motors. No more clunk - clunk motion.
[18:53:18] <SpeedEvil> I mean gimbals you stick the whole phone on.
[18:53:34] <XXCoder> thats true
[18:53:44] <XXCoder> that is if people ever remember it exists
[18:54:09] <SpeedEvil> Then there is always the 'if teh phone wasn't tehre, there would be no video' thing.
[18:54:16] <skunkworks> Thought I took a video - but I must have just taken a picture.. Duh
[18:56:55] <CaptHindsight> well the UI on the phones for the phone and camera get worse every update
[18:57:16] <CaptHindsight> it's like these devs never make phone calls
[18:57:59] <XXCoder> nor take pics or videos lol
[18:58:15] <SpeedEvil> I last made a phone call on my phone 10 years ago.
[18:58:31] <SpeedEvil> (pics and video is a very fair point though)
[18:58:45] <CaptHindsight> SpeedEvil: do you just teleport these days?
[18:58:51] <SpeedEvil> My 10yo phone (camera app comes on when you open the physical shutter) is arguably better.
[18:59:15] <XXCoder> lol once people can teleport there go whole vehicle industry, roads, phones
[18:59:27] <XXCoder> airplane industry and airports too
[18:59:30] <CaptHindsight> he might be from the future
[18:59:59] <CaptHindsight> his telepod might have crashed or malfunctioned stranding him here
[19:07:44] <CaptHindsight> https://www.youtube.com Laser welding in Super Slow Motion
[19:08:42] <XXCoder> gonna love how much it looks like water.
[19:08:46] <XXCoder> or even mecury
[19:09:17] <XXCoder> man time scale is so brief
[19:11:42] <SpeedEvil> :)
[19:12:20] <Tom_itx> do they use filler while laser welding?
[19:14:29] <SpeedEvil> Tom_itx: some processes do
[19:15:36] <SpeedEvil> It's more autogenous though in general I think.

[19:24:28] <andypugh> Taking shape… https://photos.app.goo.gl One original and two clones in process.
[19:24:50] <XXCoder> nice
[19:25:02] <XXCoder> order or for youself?
[19:25:38] <andypugh> One for myself, one spare to sell or in case of something going wrong.
[19:25:55] <XXCoder> not bad idea. easier to make 2 same time.
[19:26:21] <andypugh> Yes, it’s a habit I have got in to. Make 2, or 3, and keep the best one.
[19:27:13] <CaptHindsight> andypugh: https://forum.linuxcnc.org
[19:27:13] <jthornton> what is the offset for on the base?
[19:27:38] <CaptHindsight> jthornton: you and PCW are tied for 2nd place :)
[19:32:12] <XXCoder> https://www.youtube.com
[19:32:23] <XXCoder> sucky camera warning
[19:32:48] <XXCoder> he usually dont do handcams thankfully so its just showing stuff at start
[19:42:37] <XXCoder> so that material type grabs oil and stays wet with it
[19:42:44] <XXCoder> keeping machine lubicated
[19:43:01] <XXCoder> i wondered why some parts at work was made with those stock. I know now I guess
[19:44:08] <Tom_itx> it's rather abrasive isn't it?
[19:44:17] <XXCoder> not as bad as fiberglass
[19:44:22] <XXCoder> but yes
[19:44:38] <Tom_itx> phenolic?
[19:44:50] <XXCoder> no idea what that word is
[19:44:55] <Tom_itx> looks like it
[19:47:54] <XXCoder> interesting
[19:49:29] <XXCoder> one board, 1/4 inch 12"x24" is 32 bucks absically
[19:50:18] <XXCoder> 84 bucks for same but half inch
[19:52:57] <gregcnc> the amount of time he spends on custom tooling is incredible
[19:53:06] <XXCoder> no crap
[19:53:35] <XXCoder> im pretty sure he was very very expensive worker, and worth it when he wasnt retired
[19:53:53] <gregcnc> I don't think he is retired
[19:54:46] <XXCoder> dunno he talked about going to place he used to work at, maybe just moved on from. dunno
[19:57:32] <XXCoder> millions of slots each of em have to be "dermeled" ouch
[19:58:22] <gregcnc> tedium doesn't bother him, that's why he is good at what he does
[19:58:50] <XXCoder> it does or does not for me, sometimes i just grind away at work and wow shift is done already
[19:58:54] <XXCoder> but sometimes not
[19:58:56] <gregcnc> most people would give up at that's close enough
[19:59:55] <XXCoder> hes sealing those away while working on other aways.
[19:59:59] <XXCoder> parts*
[20:00:06] <XXCoder> so it dont have dirt or something
[20:09:48] <MarcelineVQ> like that circular dovetail cutting pattern at 24:00
[20:14:36] <hazzy-m> https://www.instagram.com
[20:15:22] <XXCoder> marc yeah that was interesting
[20:16:16] <XXCoder> arudinos dunno lol
[20:16:30] <XXCoder> I want a pendant or in least board controls but dont know hoiw to do it
[20:18:06] -!- CaptHindsight has quit [Remote host closed the connection]
[20:18:38] <hazzy-m> I've been using the 8bit ADCs on the 7i76 for reading pot overrides, but they drift very badly, the ones on the arduino seem better so far ...
[20:19:00] <hazzy-m> would not trust the arduino for anything critical though
[20:23:11] <skunkworks> hazzy-m: I think andypugh make a smart serial slave out of an arduino...
[20:23:46] <hazzy-m> oh, that would be nice!
[20:24:42] <skunkworks> hazzy-m: or a... https://mesaus.com
[20:27:58] <hazzy-m> I was planning to get that, but decided to play with the Arduino and see if it might work well enough
[20:28:22] <hazzy-m> all I have are three pots to read, nothing critical

[20:59:00] <XXCoder> lol fancy
[20:59:08] <norias> wtf
[20:59:21] <XXCoder> i dont know if it works well under stress of daily work
[20:59:31] <norias> hate it
[20:59:36] <norias> next.
[20:59:44] <XXCoder> $5 blade! because of dumbass logo on it
[20:59:53] <XXCoder> im so ordering it lol
[21:00:17] <norias> i hate any utility knife that isn't fixed blade
[21:00:25] <XXCoder> i bought 100 for $8 something. used 15 of em in rebuild
[21:00:33] -!- justanotheruser has joined #linuxcnc
[21:00:38] <gregcnc> just happened to click his YT showing a shop he bought
[21:00:49] <XXCoder> so many drywall cutting lol
[21:01:07] <norias> i'm actually really picky about my utility knife
[21:01:16] <norias> there's one specific model i prefer
[21:01:26] <norias> of course, i'm a plasterer's son
[21:01:34] <norias> i grew up with them
[21:02:42] <Rab> That doesn't look very ergonomic.
[21:03:00] <XXCoder> Rab: hmm didnt think of that but yea
[21:03:08] <XXCoder> imange holding that cutting drywall for hours.
[21:03:17] <XXCoder> them rounded but still sharp corners
[21:03:28] <Rab> I guess if you want your EDC utility knife to approximate the painful experience of trying to use your EDC Leatherman pliers...
[21:04:06] <gregcnc> no people just keep it in their pocket to open amazon boxes
[21:07:25] <gregcnc> I carry one of these https://www.knifecenter.com
[21:07:56] <XXCoder> i dont carry a knife. amazon boxes I just open by hand. easy enough.
[21:08:07] <XXCoder> probably from days I used to break hundreds of boxes a day
[21:08:31] <SpeedEvil> https://www.aliexpress.com for me on a neckchain.
[21:08:47] <SpeedEvil> On a 'ID retractor'.
[21:08:49] <SpeedEvil> So handy
[21:09:13] <XXCoder> for work I have slide out breakable blade
[21:09:28] <XXCoder> easy enough to use plier break blade and theres fresh part
[21:09:29] <gregcnc> also some flavor of swisstool
[21:09:47] <XXCoder> its $1 and its still in use for couple years lol
[21:10:37] <andypugh> I haven’t even started the Arduino sserial slave, though I do think it’s a good idea. Though I have decided that I will probably use this instead, more CPU higher serial rate: https://www.adafruit.com
[21:13:04] <andypugh> Puzzled by him buying bearings and destrying them, you can buy loose needles: https://simplybearings.co.uk
[21:13:48] <SpeedEvil> ^hah also.
[21:13:57] <XXCoder> 100 for 12 pound
[21:14:06] <SpeedEvil> The above knife is pictured before the 'route out liner lock step
[21:14:35] <XXCoder> dunno where he lives at but maybe price isnt worth it, or maybe shipping isnt possible or too expensive?
[21:15:08] <SpeedEvil> Or just spending another few minutes to save $2 isn't worth it.
[21:15:27] <SpeedEvil> He does not seem to be focussed on cost.
[21:16:32] <andypugh> I am not 100% convinced that he will get a reult better than the original prismatic eays
[21:16:44] <SpeedEvil> I do hope he posts results.
[21:17:00] <SpeedEvil> It's an interesting project
[21:17:20] <XXCoder> indeed
[21:17:45] <XXCoder> its not something i would use, likely but still interesting, and I learned something about that material
[21:18:30] <SpeedEvil> I suspect also if you were somewhat more cavalier in your attitude, you could put it in fuzzy, and let the filters catch the fuzz
[21:18:45] <andypugh> I have hours of footage of my fixed steady manufacture. I probably should publish it, as it’s pretty unusual as CNC horizontal milling.
[21:20:20] <XXCoder> phenolic i milled those bunch of time but loearned what it is by that video
[21:21:14] * norias perks up.
[21:21:22] <norias> andypugh: horizontal milling?
[21:22:55] <andypugh> There is a UK brand called “Tufnol” with a bizarre naming scheme. “Carp Brand” “Whale Brand” etc: Carp, Vole, Whale, Crow and then numbers. there must be a fun story there.
[21:23:09] <XXCoder> is this good deal I wonder https://www.aliexpress.com
[21:23:25] <andypugh> norias: Yes, I decided that for the parts i am making the horizontal spindle makes more sense
[21:23:46] <norias> andypugh: what machine is this?
[21:23:56] <andypugh> Harrison Universal
[21:24:16] <norias> googling now
[21:24:36] <norias> ahh, badass
[21:24:56] <norias> cnc?
[21:25:09] <XXCoder> andypugh: upload it. whynnot?
[21:26:07] <andypugh> norias: Unedited, https://www.youtube.com
[21:26:49] <andypugh> Not originally CNC, I modified it.
[21:27:04] <norias> very cool
[21:27:11] <XXCoder> linuxcnc?
[21:27:19] <andypugh> Of course :-)
[21:27:32] <XXCoder> nice
[21:27:36] <XXCoder> ui looks different
[21:27:37] <norias> i have a soft spot of horizontal spindles
[21:28:12] <XXCoder> andy I really want encoder wheel and knobs pendant even if machine is small
[21:28:17] <XXCoder> using keyboard is INSANE
[21:28:24] <XXCoder> i feel so unsafe using keyboard
[21:28:47] <andypugh> The UI is “Touchy"
[21:29:07] <XXCoder> did you see jthornton's work on documing new ui style?
[21:29:13] <XXCoder> its FAR more customizable
[21:29:55] <andypugh> Glade (including Gscreen) is very cutsomizable. Except Glade is buggy and PyGTK is unsupported and buggy
[21:30:12] <XXCoder> its not glade but interesting
[21:30:20] <XXCoder> lets see if I saved link
[21:30:27] <andypugh> norias: Horizontals can be so much more rigid.
[21:30:35] <norias> aye
[21:30:45] <XXCoder> i'd think so, tools is held on both ends
[21:30:49] <XXCoder> https://forum.linuxcnc.org andypugh
[21:31:05] <andypugh> XXCoder: I have been folloeing develipment on the forum
[21:31:12] <norias> i sorta want to make a hobby cnc that's horizontal
[21:31:16] <XXCoder> i dont read forums unfortunately lol
[21:31:17] <norias> like, tormach sized
[21:31:22] <norias> modern horizontal
[21:31:32] <XXCoder> wow interesting
[21:31:34] <norias> hsk spindle, tool changer, etc
[21:31:40] <andypugh> I moved the steady nearer the drive end for other ops, to make it even stiffer.
[21:31:42] <XXCoder> there is some stuff horzionals is just best on
[21:32:00] <andypugh> Though I have concluded that my arbour is bent. Not sure what to do about that.
[21:32:39] <norias> i've been reading about motor design
[21:32:45] <norias> so i can design a motorized spindle
[21:32:56] <norias> or understand what i'm buying if i buy one
[21:33:11] <norias> i was thinking of doing the spindle as a "government project" at work
[21:33:24] <norias> i could heat treat and cylindrical grind whatever i need
[21:37:44] <andypugh> I think that you would need a gearbox for a horizontal spindle. I am running at 100rpm at the moment, and that isn’t even wth a particularly big cutter.
[21:39:31] <XXCoder> andy cant buy replacement arbour? or use lathe to make one after reverse engineering?
[21:40:07] <XXCoder> im sure not even remotely compliant to your model mill but https://www.victornet.com
[21:40:19] <norias> andypugh: why a gearbox?
[21:40:46] <andypugh> Arbours come up occasionally on eBay, but are quite expensive. I definitely could make one, and have made 1 1/4 and 27mm ones for gear hobs.
[21:41:43] <andypugh> norias: To get the speed range. My mill runs from 45 to 1000 rpm. You won’t get that with a direct drive, and the 1000 is annoyingly slow.
[21:42:27] <norias> hmm, yeah, i don't know yet
[21:42:53] <norias> what is it, though, a 220V single phase induction motor driving your spindle?
[21:43:37] <XXCoder> is it upgradable?
[21:44:24] <andypugh> It was originally a 440V three-phase. I had it rewired internally for 24-V three-phase and run it through a VFD for infinitely variable speed. Lowest speed is 1 rpm. (and it’s unstoppable)
[21:44:44] <andypugh> (240V 3-phase)
[21:45:32] <norias> ahh, ok
[21:46:11] <andypugh> Here is an unusual use for the lowest speed, with the VFD wound down, https://www.youtube.com
[21:47:13] <XXCoder> nice
