12:25 AM ChunkyPuffs: gloops where you at
12:33 AM ChunkyPuffs: hey gloops
12:33 AM ChunkyPuffs: streaming, trying to cut out some major shit
12:33 AM ChunkyPuffs: gonna try and do 3mm passes on a tool
12:33 AM ChunkyPuffs: https://twitch.tv/memetic_
12:38 AM ChunkyPuffs: gloops, you said you do 2000 mm/min with a 3mm bit at 14k rpm?
12:53 AM ChunkyPuffs: Tom_L, You still around? :D
12:53 AM ChunkyPuffs: I need to ask about chip rate
12:54 AM ChunkyPuffs: https://www.cnccookbook.com/cnc-feed-rate-calculator/
12:55 AM ChunkyPuffs: this thing, how do I find an ideal chipload for my bit?
12:59 AM ChunkyPuffs: Tom_L, In fact, I think I'm starting to get it
12:59 AM ChunkyPuffs: how do I figure out what pass depth is best for my material?
01:24 AM MarcelineVQ: ChunkyPuffs: it will depend on tool sitckout, machine rigidity, and how well the stock material is affixed. you will have to test it out to determine what's best for yours. I wouldn't recommend deeper than the endmill is wide for initial test runs. Start shallow and work your way up to what seems good with a few test cuts. listen to the cut, when you're getting too deep you can often hear a difference due to the vibrations being
01:24 AM MarcelineVQ: introduced from the tool deflecting
01:34 AM ChunkyPuffs: So the guess work is in only the passes you can do with a tool?
01:35 AM ChunkyPuffs: so 3mm vs 1mm per pass is guesswork, but everything else is science
01:35 AM MarcelineVQ: I don't understand the question
01:37 AM gloops: common sense approach - start with light cuts slow feed
01:38 AM gloops: 0.1mm pass, the lowest spindle speed practical, slow feed, 400mm/min
01:39 AM gloops: these calculators assume ideal conditions, totally rigid machine etc, this is a router
01:49 AM gloops: what will happen with deep/fast cuts, even though in theory the feed speed and cut is right (chipload) the machine wont be strong or rigid enough to hold the cut, it will vibrate and deflect causing the cut to be erratic and snap tools etc
02:04 AM Deejay: moin
02:13 AM ChunkyPuffs: gloops, why are you suggesting that I wait days for my cuts to finish
02:14 AM ChunkyPuffs: I don't know what planet you're on
02:14 AM gloops: haha, youll soon be on the same planet im on
02:15 AM gloops: you wont be cutting 3mm i dont think, or 1mm
02:15 AM ChunkyPuffs: Ijust successfully cut a piece out of 3mm passes, just fine, no worry whatsoever
02:15 AM ChunkyPuffs: I just succesfully planed at 2mm
02:16 AM ChunkyPuffs: although I don't feel comfortable at 2mm 2000mm/min
02:16 AM gloops: well ill concede on this occassion then
02:42 AM CaptHindsight: https://www.crowdsupply.com/class-b-project/motionpro-6600-motion-controller
02:42 AM CaptHindsight: stepper drivers capable of driving up to four NEMA 17/23/34 motors at up to 4 A per motor
02:42 AM CaptHindsight: up to 16 micro-steps
02:43 AM CaptHindsight: $250
02:43 AM sensille: comes with grbl?
02:44 AM sensille: just for convenience, i guess
02:44 AM CaptHindsight: doesn't have any smarts except for the stepper drivers current limiting as far as I can tell
02:45 AM CaptHindsight: https://classbproject.com/motionpro-6600-documentation/
02:46 AM sensille: that's what they say
02:46 AM sensille: but it's not really a bargain, why do they have to be that expensive?
02:47 AM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver/mx4660/
02:49 AM CaptHindsight: oh geez TB6600 drivers
02:52 AM gloops: yes the old faithful
02:52 AM gloops: 4 in one driver has the drawback - one goes, the lot is kaput
02:53 AM CaptHindsight: has a AVR opn board for GRBL and USB , oh noes
02:53 AM CaptHindsight: opn/on
02:54 AM CaptHindsight: goes back to zzz
04:09 AM XXCoder: booyah
05:12 AM Tom_L: morning
05:22 AM Tom_itx is now known as Tom_L
05:22 AM XXCoder: hey tachoknight
05:22 AM XXCoder: er Tom_L
05:24 AM XXCoder: hey jt
05:27 AM selroc: aloha
05:28 AM XXCoder: hey
05:28 AM jthornton: warming up a bit today to 40F
05:30 AM jthornton: last two nights a hen has laid an egg from the roost
05:31 AM XXCoder: high 40s f all day and night. also rain all day and night
05:32 AM jthornton: wet and cold not any fun
05:32 AM XXCoder: yeah
05:32 AM XXCoder: got MASSIVELY splashed on way home
05:32 AM XXCoder: couldnt see for few 60 mph seconds
05:33 AM jthornton: yikes
05:33 AM XXCoder: yeah
05:34 AM jthornton: I spent all afternoon reverting reconciliations on my business accounts until I got back to June
05:35 AM jthornton: finally got them all reconciled... what a pia to have 4 accounts linked to each other
05:35 AM XXCoder: sounds fun
05:38 AM jthornton: after having my business account hacked through paypal I setup a buffer account that I use to receive transfers from paypal then I transfer out of that to a holding account the business account gets funds from the holding account because I've had it hacked through the debit card lol
05:40 AM XXCoder: ugh
05:40 AM jthornton: now I need to figure out a way to order from alexpress without using a regular bank account because they deny payment to them lol
05:48 AM gloops: dont talk to me about splashing lol, went through some water yesterday now van wont do more than 20 lol
05:48 AM XXCoder: doh
05:51 AM jthornton: electrical issue?
06:02 AM _abc_: Hi. Does anyone know if pipe cutter wheels, hardened steel, can be relatively easily mounted on a bearing of some sort for machining (scoring) purposes?
06:02 AM _abc_: Things like these https://www.homedepot.com/p/Imperial-Replacement-Tube-Cutter-Wheel-Set-3-Piece-TC1B/301045439
06:02 AM _abc_: Obviously the original journal "bearing" is better ignored.
06:04 AM _abc_: Ahh they make them with ball bearings too - nice
06:04 AM _abc_: https://www.amazon.com/RIDGID-29973-Stainless-Replacement-Bearings/dp/B003T0FVLG/ref=pd_sim_469_6/131-2815215-6787411?_encoding=UTF8&pd_rd_i=B003T0FVLG&pd_rd_r=1841c75f-f305-11e8-93f7-555294ed87de&pd_rd_w=xXF2A&pd_rd_wg=Fmcwz&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=18bb0b78-4200-49b9-ac91-f141d61a1780&pf_rd_r=7J9CZ52QYB51SRZNGVDB&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=7J9CZ52QYB51
06:04 AM _abc_: SRZNGVDB
06:04 AM _abc_: eww
06:04 AM _abc_: https://www.amazon.com/RIDGID-29973-Stainless-Replacement-Bearings/dp/B003T0FVLG/ref=pd_sim_469_6/131-2815215-6787411 -- should work
06:05 AM jthornton: you don't have to post anything after /ref inclucing /ref
06:05 AM _abc_: So, has anyone attached such a wheel to a cnc to score/rut material with? There's usually an extra A axle motor to set the wheel angle orientation on the material.
06:06 AM XXCoder: some spindle can set its position and hold
06:06 AM jthornton: wow that has a roller bearing, I've thought of using one to make a wire stripper
06:06 AM _abc_: I don't have such a thing.
06:07 AM XXCoder: well theres another otion, just move around adjusted for rotating
06:07 AM XXCoder: possible have "strach sheet" used only for rotating it
06:07 AM _abc_: Trailing link like mode is used on some PVC cutters. Roland etc.
06:07 AM _abc_: That is not ok for heavy duty use normall. It can be used but it's a hack
06:08 AM _abc_: normally
06:08 AM _abc_: Ridgid is a big name in tools? I do not see anything from them in Europe.
06:09 AM _abc_: Okay so I know what to look out for.
06:48 AM jthornton: wow I can use a GB per day for the rest of the month lol
06:49 AM Jymmm: jthornton: gone in sixty seconds
06:49 AM XXCoder: fancy
06:50 AM Jymmm: jthornton: Can't you rent a hilltop and toss up a cell repeater?
06:50 AM _abc_: Rent a hilltop?!
06:50 AM Jymmm: _abc_: Yes, that'show many transmitters are done commercially
06:51 AM XXCoder: jthornton: looked some into hui?
06:51 AM XXCoder: can it make some interactable stuff or is it just display data?
06:52 AM Jymmm: _abc_: https://en.wikipedia.org/wiki/Mount_Wilson_(California)#Television_on_Mount_Wilson
06:53 AM jthornton: lets see cell data for 3GB here cost as much as 10GB of sat data...
06:53 AM Jymmm: jthornton: $50/mo unlimted tmoble prepaid,
06:54 AM jthornton: yea if you have tmobile towers around
06:54 AM Jymmm: jthornton: Do you have a hilltop to test?
06:55 AM jthornton: test what
06:55 AM Jymmm: _abc_: hilltop antenna farm... https://upload.wikimedia.org/wikipedia/commons/b/b6/Mt_Wilson_antenna_farm_winter.jpeg
06:55 AM Jymmm: jthornton: coverage availability
06:56 AM jthornton: we have att and verison only here
06:56 AM Jymmm: jthornton: as I understand it, you are in a hole/valley, yes?
06:56 AM jthornton: sorta, I'm out in the wilderness lol
06:57 AM jthornton: only a few years ago we got a tower near enough to receive cell service here and with the tower only 2 bars but enough for texting lol
06:58 AM Jymmm: jthornton: Gotcha. Well if you can get to a hilltop, you could always toss up a hardware solution to extend coverage to you. It might cost $600 in hardware, then you could use cellular
06:58 AM jthornton: that's when I got rid of my cell booster antenna lol
06:59 AM jthornton: and get cellular from where? cali?
06:59 AM jthornton: I had an $800 cell booster mounted at the top of the hill...
07:00 AM jthornton: <jthornton> we have att and verison only here
07:00 AM Jymmm: and still only 2 bars?
07:00 AM Jymmm: and still only 2 bars WITH the booster?
07:00 AM jthornton: booster is long gone
07:00 AM Jymmm: why?
07:00 AM jthornton: don't need it anymore
07:01 AM Jymmm: since you got sat data ?
07:01 AM jthornton: and it only worked in the shop
07:01 AM jthornton: no I have a cell tower a few miles away now...
07:02 AM jthornton: my neighbor tried every cell solution possible and gave up and went back to sat...
07:02 AM Jymmm: jthornton: have you considered getting all those gators to just hold up micro repeaters for ya?
07:06 AM Jymmm: Verizon is offering unlimied data prepaid for $65/mo, 8GB/$45mo
07:07 AM XXCoder: 65 a month is pretty dang cheap
07:08 AM Jymmm: AND... he could sell service to his neighbors too
07:11 AM jthornton: my neighbor lives in a trashy trailer and does not have any money
07:12 AM Jymmm: jthornton: pay with goats?
07:12 AM jthornton: they don't have any livestock only kids
07:13 AM Jymmm: jthornton: free child labor?
07:13 AM jthornton: they are too fat to do any work lol
07:13 AM Jymmm: lol
07:14 AM Jymmm: well, they can split firewood and lose weight at the same time
07:14 AM Jymmm: ...and stack it too
07:21 AM XXCoder: call it woodteris
07:22 AM XXCoder: feee games till stack of uncut wood runs out
07:22 AM ChunkyPuffs: So, I'm cutting through 10mm at a time with a 3mm bit using adaptive clearing
07:22 AM ChunkyPuffs: the guy who works for autodesk seems confident in this method of using all the flute rather than just the tip of the flute
07:22 AM ChunkyPuffs: Well, used to.
07:23 AM ChunkyPuffs: This is basically a breakthrough, it's incredible.
07:36 AM _abc_: is it?
07:42 AM gregcnc: adaptive is the answer to all world problems
07:56 AM jesseg: What is adaptive about it?
07:56 AM gregcnc: adaptive aka: high speed milling
07:57 AM jesseg: it may be too early for me to be attempting to think here... but I'm still not sure what's high speed or adaptive about simply doing a more shallow cut on a longer length of the bit..
07:58 AM jesseg: unless the high speed refers to the fact that there can be an improvement of productivity
07:58 AM jesseg: and maybe autodesk just needed some slick marketing jargon so they called it adaptive and high speed :D
07:59 AM gregcnc: that's basically it, but CAM alos calculates apprpriate entry and exit moves so as to minimize shock onthe tool
07:59 AM gregcnc: that's why you get the odd toolpaths
07:59 AM jesseg: Oh -- compiler style optimization for toolpaths?
07:59 AM jesseg: I can dig that.
08:00 AM jesseg: but I'd call it CSOFTP or simply HOTP - Highly Optimized Toolpaths :P
08:08 AM gloops: probably less stress on a 3mm tool bearing less force along the length than having all the force at the point levering on the collet?
08:08 AM gloops: whether any actual time is saved - youd have to time both
08:09 AM gregcnc: force is force
08:10 AM gloops: yes but spread
08:10 AM gregcnc: no
08:10 AM gloops: very different moment at the collet
08:10 AM gregcnc: does the collet care?
08:10 AM gloops: no but the tool does
08:11 AM gloops: if you have a 10ft crow bar fixed one end etc
08:11 AM gloops: 10lb on the tip - massive leverage
08:11 AM gloops: 1lb per foot - different matter
08:11 AM gregcnc: clearly, but if you load either to break the tool the tool is broken
08:12 AM gloops: oh yeah the tool will still snap at some point
08:12 AM gregcnc: one factor is tool wear. if you're using the whole flute, you use it all
08:13 AM gloops: yeah but you got to make more passes
08:13 AM gregcnc: I suggest you read up on it
08:13 AM gloops: i dont need it lol
08:13 AM gregcnc: if you want to talk about it
08:14 AM gloops: im learning by talking about it
08:14 AM _abc_: What type of steel is exhaust pipe made of?
08:14 AM _abc_: Stainless?
08:14 AM gloops: abc - crap
08:14 AM gregcnc: sometimes
08:14 AM gregcnc: whatever you pay for
08:14 AM gloops: mostly mild steel
08:14 AM _abc_: Let's assume it is not quite crap, but a piece of aftermarket kit bought on purpose, used
08:15 AM _abc_: Is it not high temp rated? Why is is known to be hard to weld?
08:15 AM gregcnc: i wouldn't assume anything
08:15 AM gloops: i dont know of it being high temp or anything, manifold is different
08:15 AM gregcnc: what's the real question?
08:15 AM gloops: exhausts are hard to weld because theyre usually corroded
08:16 AM _abc_: I would like to make something which is exposed to high temps and use that material
08:16 AM gloops: water vapour from the inside, the elements from outside
08:16 AM _abc_: Yes.
08:17 AM gloops: someone at the steelos made one from copper - it sagged
08:17 AM _abc_: Aren't grooved bearings carrying a VV in the type name? I found one which has VV and no groves
08:17 AM gregcnc: groove?
08:17 AM _abc_: gloops: sagged under weight or from heat?
08:17 AM gregcnc: either or both
08:17 AM _abc_: gloops: VV DIN bearings are supposed to have a V groove
08:17 AM gloops: abc heat then its own weight probably
08:17 AM gregcnc: use the spec number
08:18 AM _abc_: I am looking online for a catalog/etc based on VV in the type
08:18 AM gloops: strange im about to weld an adaptor on an exhaust
08:22 AM gregcnc: i don't think there is a DIN spec for v guide bearings
08:23 AM _abc_: There is
08:23 AM gregcnc: what's the number?
08:24 AM _abc_: https://www.vxb.com/V-Groove-Bearings-s/235.htm
08:24 AM gregcnc: DIN xxxx
08:26 AM Contract_Pilot: Sup.
09:05 AM gregcnc: Contract_Pilot are you running a path pilot lathe?
09:08 AM Contract_Pilot: Sort of put it on back burner last spring.
09:08 AM Contract_Pilot: Not much let to do to it minor tweaks.
09:08 AM gregcnc: ok I was trying to figure out if it had turning cycles like major controls
09:09 AM Contract_Pilot: Need to get some pulleys install limit switches and make a tool post.
09:34 AM weenerdog: howdy
09:39 AM jthornton: hay
09:54 AM jesseg: jthornton, hey you got chickens right?
09:55 AM methods_: he iz the chkn man
09:56 AM JT-Shop: jesseg: yes I have some hens
09:57 AM JT-Shop: did you know chickens don't cluck?
09:57 AM jesseg: JT-Shop, well, in fact I did not know that, but we may have to define "don't" or "cluck" to continue this conversation
09:58 AM methods_: does anyone really give a cluck
09:59 AM jesseg: anyway I discovered something interesting.. if you take a freshly hatched chick and hold it in your hands and breath warm air into your hands to warm up the little bugger, he'll try to climb right into your mouth because it's warm and moist. I guess he thinks he's under his mommies wing LOL
10:01 AM JT-Shop: never tried that with a fresh chick
10:01 AM JT-Shop: they are amazing actually as they can sort out everything without a mom to teach them
10:02 AM jesseg: JT-Shop, what do you mean when you say chickens don't cluck, though?
10:03 AM jesseg: I only tried it with one chick. But I tried it twice and it worked twice.
10:04 AM methods_: you're all a bunch of crazy mother cluckers
10:04 AM jesseg: on a roll there methods_ :D
10:04 AM methods_: heheh
10:04 AM methods_: i'm here all day
10:05 AM Roguish: don't give up your day job....
10:07 AM methods_: this is my day job sheesh
10:07 AM methods_: you're all a bunch of suckahs workin like slaves
10:07 AM gregcnc: it' what we pay him for
10:07 AM methods_: i tell chikn jokes professionally
10:08 AM methods_: i make $30,000 dollars a month......
10:09 AM Roguish: cheap labor.
10:09 AM methods_: heheh
10:09 AM jesseg: JT-Shop, well anyway, chickens do make a sound which I always thought was "clucking." The roosters make it when they find a fresh pile of food and they do it to call the hens over for a snack, and the hens with chicks do it to talk to the chicks and show them where food is. It sounds like this: https://www.youtube.com/watch?v=ZG3NlOgy0Zo
10:10 AM jesseg: oh that video then goes onto cackling
10:11 AM JT-Shop: no rooster here lol he was a pain in the rear so he went to freezer camp
10:12 AM JT-Shop: mine make all kinds of noises lol but never cluck
10:12 AM jesseg: JT-Shop, are we thinking about the same thing though when we say "cluck?"
10:14 AM JT-Shop: yea the rooster in the video was clucking for sure
10:14 AM methods_: hahahah freezer camp
10:14 AM methods_: i'm addin that to my chicken joke book
10:15 AM jesseg: methods_, ok you heard about the parrot that had the vocabulary of a sailor? he was always cussing and his new owner was trying to train him not to - he tried everything from cold water to rolled up news papers and the old bird just cussed all the worse.
10:15 AM jesseg: So finally he put the bird in the freezer for a few minutes to cool down.
10:16 AM methods_: hehehehe
10:16 AM jesseg: Suddenly the cussing stopped. Worried that he'd killed the bird he quickly took it out.
10:16 AM methods_: don't leave me hanging
10:16 AM jesseg: The parrot was totally changed. Completely stopped cussing.
10:16 AM jesseg: All he said was "What did the turkey do?"
10:16 AM methods_: hahahahahah
10:16 AM methods_: that's funny
10:19 AM jesseg: methods_, did you hear about this guy who was installing a new carpet for an old lady?
10:20 AM jesseg: As he was going about his job, he went to get his pack of cigarettes out of his pocket, but they weren't there, so he figured he'd left them in the truck. Not waiting to take the time to go get them he just kept on working.
10:21 AM jesseg: But as he went, he found a lump under the newly installed carpet. He figured it must be his pack of cigarettes, and not wanting to tear the carpet back up to get them, he just pounded them flat with his heel and kept on going.
10:22 AM jesseg: After he was all done, he headed out to his truck. But just as he was getting into the cab, two things happened simultaneously: He noticed his pack of cigarettes on the dash board, and he heard the lady calling out "Have you seen my parakeet?"
10:26 AM Rab: 4 minutes, still no punchline
10:26 AM jesseg: The punchline is that the thing he smashed flat under the carpet was the lady's pet parakeet bird
10:27 AM jesseg: but it was implied
10:27 AM jesseg: but I guess if I have to explain it, it's no good
10:27 AM Rab: I've owned a bunch of chickens, I'm positive I've heard hens cluck.
10:27 AM phaxx: I liked it.
10:28 AM jesseg: Rab, yeah they do. when you feed them often.
10:28 AM Rab: It was a weird dynamic because we had way too many roosters (like 1:1).
10:28 AM jesseg: or when they have chicks. I saw a friend's hen sitting on eggs yesterday and I scratched her behind the years andshe was clucking
10:30 AM Rab: We also had a hen which switched genders--like, going from normal laying/brooding/chick raising behavior, to aggressiveness and humping other hens.
10:32 AM weenerdog: bok bok
10:33 AM Rab: boKOK
10:34 AM JT-Shop: yea I have one that liked to jump on other hens back and her name is Mable (Mean Ass Bitch le) but she stopped when the other hens started doing it back
10:35 AM Rab: haha
10:38 AM weenerdog: linuxcnc = linux chickuns n clucking
10:39 AM methods_: heheh
11:29 AM weenerdog: i'm developing a love/hate relationship with fusion
11:29 AM * JT-Shop skipped the love part and went directly to hate it
11:29 AM weenerdog: except without the love
11:29 AM weenerdog: lol
11:30 AM weenerdog: maybe i'll design my build in freecad
11:35 AM Getty: XXCoder: i am an idiot, that card would never fit into that computer :D just by the power
11:36 AM Getty: XXCoder: but now i used that new card to upgrade another PC :D lol just dont know how to go from here
11:38 AM JT-Shop: Getty: XXCoder is asleep
11:43 AM Getty: JT-Shop: yeah he can read later, not important
11:46 AM Getty: i was really stupid to expect to put a high end gfx card in a pre-built dell computer, even tho if the connector fits
12:22 PM JT-Shop: well all 70 parts are done deburring the 530 holes x 2 sides for 1060 holes to debur lol
12:28 PM Getty: well, in worst case you just do it by hand <badumtss>
12:29 PM Getty: my dad actually drilled nearly everything by himself instead of using the CNC, because he said it was a good moment to think
12:29 PM Getty: he also made his boards by himself, good that all those chemicals are now gone ;)
01:47 PM gregcnc: lol time to get rich https://youtu.be/qKX7AW73i8s
01:49 PM syyl_: that guy is so full off himself
01:50 PM syyl_: yeah, fixture plates are a buisness idea
01:50 PM syyl_: because there are not enough people that are drilling holes in plate
01:51 PM CaptHindsight: have you met most uhmericans?
01:51 PM gregcnc: high end niche products made by people who have spent most of their waking hours trying to break into
01:51 PM syyl_: a hand full
01:54 PM gregcnc: though some of the things I see on instagram (other than new biax scrapers) that people make and sell for unheard of prices really blow my mind
01:54 PM CaptHindsight: youtubes are full of hardly know anythings making howto videos
01:54 PM gloops: i knew star wars would come in to it
01:54 PM gregcnc: that guy making titanium key caps...
01:54 PM syyl_: i love when they make a one off part
01:55 PM gregcnc: the guy with the golf club keychains...
01:55 PM syyl_: and think they need to push speed/feed/doc to absolute max
01:55 PM Rab: A fixture pallet system made in somebody's garage on a Shapeoko? Shut up and take my money!
01:55 PM syyl_: because otherwise the chinese will steal his job
01:55 PM CaptHindsight: time is money :)
01:55 PM gloops: what good is money with no time?
01:56 PM CaptHindsight: Rab: he has a video for that as well https://www.youtube.com/watch?v=7Py9zuhPOR4
01:56 PM syyl_: how much time did i gain when my setup failes because of pushing everything? ;)
01:56 PM gregcnc: what does this nerd guy make? he has some product
01:56 PM syyl_: heavy duty aluminum!
01:57 PM syyl_: oh boy
01:57 PM CaptHindsight: gregcnc: videos for makers
01:57 PM syyl_: am i elitist for thinking that tooling out of aluminium is disposable? ;)
01:57 PM CaptHindsight: syyl_: depends on your perspective
01:57 PM gregcnc: sometimes that is the point
01:58 PM CaptHindsight: if you let hardly know anythings define you then maybe
01:58 PM Rab: First comment on that second video: Jan Detlefsen 2 months ago What are you guys actually producing?
01:59 PM syyl_: that unboxing video is as useless as
01:59 PM syyl_: um
01:59 PM syyl_: dont know
01:59 PM CaptHindsight: syyl_: what if you have never opened a box before?
01:59 PM syyl_: i think most humans can adapt to that concept pretty fast
02:00 PM syyl_: using a sharpened rock to slice open something
02:00 PM Rab: What if you've never sat through 30 seconds of Haas splash screens before?
02:00 PM CaptHindsight: deserves a video howto :)
02:00 PM syyl_: i will do videos on trivial things too
02:00 PM syyl_: but man. unboxing without checking anything on it?
02:01 PM CaptHindsight: how to not miss the bowl when relieving yourself
02:01 PM syyl_: throw it on a surface plate and run a indicator over it
02:03 PM CaptHindsight: which shoe or sock do you put on first?
02:03 PM CaptHindsight: lets move on to the important questions
02:03 PM syyl_: :D
02:04 PM CaptHindsight: why are all the videos on how to use some software applications always using some version that only they have or with mysterious plug-ins?
02:04 PM CaptHindsight: or they don't edit out their mistaken mouse clicks
02:05 PM syyl_: or edit at all
02:05 PM CaptHindsight: I watched >10 videos on inkscape to g-code examples
02:05 PM syyl_: haha
02:05 PM syyl_: a world of pain
02:05 PM CaptHindsight: before I just tried stuff
02:07 PM Rab: Quality comment: https://www.youtube.com/watch?v=7Py9zuhPOR4&lc=UgxpgfKOoQdqjSPhvQF4AaABAg
02:07 PM CaptHindsight: yeah, no good docs, but it does work once you get the hang of how they thought about it
02:07 PM CaptHindsight: Russian to English docs didn't help much
02:08 PM CaptHindsight: http://www.scorchworks.com/index.html this dev is interesting
02:08 PM Rab: I started with the just try stuff...I only know how to do one thing in gcodetools as a result, but I sure know how to do it, and I'm terrified to deviate.
02:09 PM CaptHindsight: he doesn't have much for tools but his software works
02:09 PM CaptHindsight: and he doesn't use github
02:09 PM CaptHindsight: Rab: I spent a few days just trying things...
02:10 PM CaptHindsight: the frustrating things is that you get no feedback or missleading feedback when converting objects to paths and then paths to g-code
02:11 PM LeoNerd: inkscape->gcode is almost universally terrible, I find
02:11 PM gregcnc: this appears to be him. looks like he's vacuum forming the bodies
02:11 PM gregcnc: http://rawspeedrc.com/
02:11 PM LeoNerd: No decent plugins for generating it directly. inkscape's DXF output is rubbish, so no luck there either
02:12 PM LeoNerd: jscut.org isn't *too* bad but it's not great for doing anything repeatably, and it takes a long time of lots of manual clicking to get any useful results
02:13 PM Rab: CaptHindsight, I've learned to inspect objects/paths in "Edit paths by nodes" mode, saves a ton of heartache. As for gcode feedback...don't you get the gcode path preview overlay?
02:14 PM CaptHindsight: Rab: yes but maybe it's my version of Inkscape when I select an object I often get not object selected when running convert to paths yet the paths show up
02:14 PM CaptHindsight: not/no
02:14 PM Rab: The little lines and arrows pop up on the screen after running path to gcode: http://reboots.g-cipher.net/rabbot/image/spacer_toolpaths.png
02:15 PM CaptHindsight: Rab: if successful I get those as well, but I'll also get blank g-code output with divide by zero as an error
02:16 PM CaptHindsight: http://www.scorchworks.com/Dmap2gcode/dmap2gcode.html
02:17 PM CaptHindsight: generates g-code to cut depth
02:17 PM CaptHindsight: based on a gray scale image darkness or lightness
02:17 PM CaptHindsight: this is the one that comes included with LCNC
02:18 PM CaptHindsight: Rab: do you use it to engrave just the outlines or also all the fills?
02:18 PM Rab: CaptHindsight, might be worth your while to mess with the options in the Path to Gcode and Preferences tabs of the plugin, particularly making sure that 'Minimum arc radius' is something sane.
02:18 PM CaptHindsight: is 0.000001mm asking too much :)
02:20 PM Rab: CaptHindsight, I've tried to do automatic fills. I've done fills the hard way, i.e., laying down a bunch of paths the width of the tool to cover an area.
02:20 PM CaptHindsight: I was looking all this over before writing some 5-axis CAM for CNC inkjet and airbrush
02:20 PM Rab: uhh make that "I've never tried to do automatic fills"
02:21 PM CaptHindsight: the interesting part I need to write is "tools" for airbrush since it's variable like a V-shaped cutter
02:22 PM Rab: CaptHindsight, have you looked at the Eggbot print driver for Inkscape? Seems like it might be very similar in concept.
02:23 PM fragalot: syyl_: moral of the story: never trust a youtuber.
02:23 PM syyl_: yes
02:23 PM syyl_: agreed
02:23 PM CaptHindsight: open the nozzle 0.05mm and you get a .2mm line, 0.1mm and .5mm line etc
02:23 PM syyl_: and yes i know that i am part of the problem :D
02:23 PM Rab: I haven't delved into it at all, but supposedly the purpose is to warp a rectangle over the surface of an egg (and then draw it with the EggBot). https://github.com/evil-mad/EggBot/releases/tag/2.7.1
02:24 PM CaptHindsight: Rab: yes, saw that
02:25 PM CaptHindsight: rab scortshworks will do that
02:25 PM CaptHindsight: Rab: https://imgur.com/a/NYNWYAX cnc airbrush on contoured parts
02:27 PM syyl_: speaking of youtube
02:27 PM Rab: CaptHindsight, are you moving Z-axis to match the contour for consistent line width?
02:27 PM syyl_: grimsmo has a new video
02:27 PM syyl_: they always seems so funny clueless
02:28 PM CaptHindsight: Rab: the airbrush can vary the line width by modulating the needle valve, it will be 5-axis
02:28 PM CaptHindsight: as well as adjusting the nozzle air pressure
02:29 PM Rab: CaptHindsight, 5-axis motion? So you will also be able to draw lines down the sides of the contours? :)
02:29 PM CaptHindsight: Rab: yes
02:30 PM Rab: CaptHindsight, sounds non-trivial but excellent.
02:30 PM CaptHindsight: the line widths are continuously variable
02:30 PM CaptHindsight: well from 0.15mm to ~25mm
02:31 PM CaptHindsight: am able to spray lines at 1m/sec
02:31 PM CaptHindsight: so coloring an egg would be a few seconds
02:32 PM Rab: CaptHindsight, can you reliably turn the airbrush on/off entirely? Like, without blobs or other artifacts at the line ends?
02:32 PM CaptHindsight: yeah
02:32 PM fragalot: if you use good quality valves in the right locations, sure
02:33 PM CaptHindsight: https://i.imgur.com/EAF5oPj.jpg
02:33 PM MarcelineVQ: can you vary the paint and air independently?
02:33 PM fragalot: we run our spray nozzles at up to 250Hz
02:33 PM Rab: I guess that's happening in the pics, although looks like there's some dwell in a few places.
02:33 PM MarcelineVQ: Because you could auto-paint the shit out of a model if you could
02:33 PM CaptHindsight: yeah, that was trying inksacpe and g-code tools with some hand editing
02:33 PM Rab: Yeah, this would be awesome for model graphics.
02:34 PM CaptHindsight: custom (low volume) parts
02:35 PM CaptHindsight: vs in mold labelling/decorating
02:35 PM CaptHindsight: also for anodizing graphics
02:35 PM Rab: ooo yeah
02:35 PM CaptHindsight: http://i.imgur.com/YWTTTte.jpg
02:36 PM CaptHindsight: targeting something like a gun stock, receiver and barrel in a minute or two
02:37 PM MarcelineVQ: What's the common method for that sort of thing? permanent decals?
02:37 PM CaptHindsight: I've been doing this with inkjet for several years but inkjet can't handle recesses over 2mm
02:37 PM Rab: Looks like that gun was hydrodipped: http://www.hydrodip.com/
02:38 PM CaptHindsight: Rab: yeah so it's not anodized, so it will come off pretty easilt
02:39 PM Rab: I wondered how robust that film was.
02:39 PM CaptHindsight: it's not
02:39 PM CaptHindsight: you have to overcoat
02:39 PM fragalot: that's why they typically clear coat it
02:39 PM CaptHindsight: but you can put a clear powder coat over
02:39 PM Rab: I guess there are serious indelible airbrush inks?
02:40 PM CaptHindsight: you can airbrush powdercoat as well
02:40 PM CaptHindsight: for anodize you print into the pores before sealing
02:40 PM CaptHindsight: so the aluminum gets anodized but before sealing you print into the nanopores, then seal
02:41 PM Rab: Let me guess, next project after/during 5-axis CAM is multiple brush heads? ;)
02:41 PM CaptHindsight: one brush, 4 color CMYK
02:41 PM CaptHindsight: for in the nozzle blending
02:41 PM Rab: You can mix in the airbrush?
02:41 PM Rab: wow
02:41 PM CaptHindsight: there is a spot color airbrush
02:41 PM fragalot: how long does it take to change colors?
02:42 PM CaptHindsight: let me find the link
02:42 PM CaptHindsight: https://www.madisonartshop.com/spectrum-2000.html
02:43 PM CaptHindsight: they just have a valve that swaps color lines
02:43 PM CaptHindsight: so it's at least a few mL between color changes
02:43 PM CaptHindsight: rather several mL
02:44 PM Rab: Silentaire needs to take some better product photos.
02:44 PM fragalot: I wonder if they have a cleaning liquid in between to flush the old color through without wasting ink
02:45 PM CaptHindsight: fragalot: I don't have one but I have heard that it just wastes ink between changes
02:45 PM Rab: All the vendors are using the sorry graphic on this page: https://www.silentaire.com/silentaire/spectrum.asp
02:45 PM CaptHindsight: ink is cheap to make, well many inks
02:46 PM fragalot: perhaps, but it still feels "wrong" :)
02:46 PM CaptHindsight: yeah wasn't their goal
02:47 PM CaptHindsight: I'm still working on the 4-color brush
02:47 PM CaptHindsight: no waste for color changes is the goal
02:48 PM fragalot: no waste will not be possible if you want them to actually mix, but it is possible to minimize it so much that you could potentially hide the changes under the dark spray areas
02:48 PM CaptHindsight: or rather have continuously variable color
02:49 PM CaptHindsight: if you have dark areas you can hide them in or you just make a rapid to the gutter and dump ink
02:49 PM fragalot: yup
02:50 PM CaptHindsight: single nozzle inkjet off the shelf runs at up to ~1200 drops/sec
02:50 PM fragalot: I wonder how clean you can get the nozzle in between colors if you air blast it into the gutter first
02:52 PM fragalot: inkjet is a pretty neat tech, unless if you use electrostatic deflection on it, and you are the technician that needs to align it
02:52 PM CaptHindsight: continuous inkjet
02:52 PM CaptHindsight: CIJ
02:54 PM CaptHindsight: I used some diesel fuel injectors a few years ago
02:55 PM fragalot: fuel injectors work really well, but they do NOT like water
03:08 PM CaptHindsight: Rab: 5-axis machines aren't cheap, so not sure if it's for the hobby market
03:09 PM CaptHindsight: I guess you could use a cheap chinaco 5-axis

03:42 PM CaptHindsight: you can see in the t-slot that inkjet can't reach more than a couple mm into a recess
03:49 PM Deejay: gn8
03:58 PM CaptHindsight: who makes a decent drill press these days for sale in the US?
04:00 PM CaptHindsight: https://www.mscdirect.com/product/details/80631815
