04:41 AM Loetmichel: *sigh* i HATE HP switches... coworker: "can you configure this FF5700 to do 4 Vlanslinked thru for measuring?" $me: "i have NO idea about HP console commands, do you expect me to learn a new script language on the fly with an $xxxx device?" turns out: my boss DOES expect me to :-(
04:55 AM Loetmichel: soo, called HPE support... letz see if there is someone who can use me as "remote hands" to walk me thru that over telephone ;)
05:01 AM Jymmm: Loetmichel: Hope you have a support contract =)
05:02 AM Loetmichel: i have now ;)
05:02 AM Loetmichel: ... waiting on the callback
05:04 AM Jymmm: Loetmichel: How much did that cost?
05:07 AM Jymmm: Loetmichel: Manual http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c04406879-4.pdf
05:18 AM Jymmm: Page 94 - Enabling automatic configuration archiving
05:23 AM jthornton: morning
05:25 AM Tom_L: morning
05:26 AM Tom_L: 78°F already
05:26 AM Tom_L: Hi 97
05:30 AM XXCoder: boo
05:30 AM jthornton: 72°F here with a high of 88°F
05:31 AM XXCoder: 54f here
05:31 AM XXCoder: yeserday was quiet cloudy till late, then HEEEAVY rain
05:31 AM XXCoder: first in weeks
05:31 AM XXCoder: jthornton: most of shop office and regions like deburr room is now led lit
05:32 AM XXCoder: half of main machines area is led lit now
05:34 AM jthornton: are they the motion activated kind?
05:35 AM XXCoder: yeah
05:35 AM XXCoder: it seems bit dimmer than old lights but not a lot
05:36 AM XXCoder: but odd to see parts of shop dark
05:39 AM jthornton: a local factory I do a lot of work in swapped out all they 1000w MH lights for motion activated LED fixtures
05:39 AM XXCoder: found out its free from tacoma city, they are working hard to end cf lights
05:40 AM XXCoder: side postive for me is old lights is quite hot, new led ones will keep shop cooler during hot days
05:40 AM jthornton: yea that's a plus
05:41 AM XXCoder: still remember first year I worked there lol
05:41 AM XXCoder: it reached 110f
05:41 AM jthornton: yuck
05:41 AM XXCoder: it was hell weeks
05:41 AM XXCoder: 110f lasted 2 work days
05:42 AM XXCoder: but weeks after and before was over 100 too
06:19 AM XXCoder: interesting use of mill https://www.youtube.com/watch?v=TtBeYsx0kEs&
06:24 AM Loetmichel: Jymmm: nothing. we are a "hp partner" ;)
06:32 AM beachbumpete1: Mornin' :)
07:07 AM XXCoder: besides making metal black colored, what does super blue do anyway
07:20 AM Tom_L: gets your fingers dirty
07:20 AM Tom_L: true blueing is done with heat
07:22 AM Tom_L: motion activated lights are for lazy workers that want to nap
07:23 AM XXCoder: lol
07:23 AM XXCoder: okay o what true bluing does?
07:23 AM Tom_L: i don't know if it protects the metal any or not but it looks cool
07:24 AM Tom_L: 'gun blue'
07:25 AM Loetmichel: its only cosmetic i belive
07:26 AM Loetmichel: at least bruied steel DOES rust
07:26 AM Loetmichel: Blued
07:26 AM Tom_L: Bluing also helps to maintain the metal finish by resisting superficial scratching, and also helps to reduce glare to the eyes of the shooter when looking down the barrel of the gun. All blued parts still need to be properly oiled to prevent rust.
07:26 AM Loetmichel: i figured as much
07:26 AM XXCoder: interesting. thankls
07:27 AM Tom_L: Steel in a tempering oven, held at 205 °C (401 °F) for a long time, will begin to turn brown, purple or blue, even though the temperature did not exceed that needed to produce a light-straw color. Oxidizing or carburizing heat sources may also affect the final result.
07:27 AM Loetmichel: XXCoder: its just a layer of iron (II) oxide
07:28 AM Tom_L: https://upload.wikimedia.org/wikipedia/commons/thumb/8/89/Tempering_standards_used_in_blacksmithing.JPG/300px-Tempering_standards_used_in_blacksmithing.JPG
07:28 AM Loetmichel: which is while harder than steel still softer than diamond for example, also not chemically stable like colourless chrominum oxide (thats what protects stainless stell from rusting)
08:25 AM gregcnc: oddball fanuc mill https://indianapolis.craigslist.org/for/d/danville-rare-fanuc-cnc-milling-machine/6916984942.html
08:40 AM Inline is now known as Guest82382
08:44 AM Inline_ is now known as Inline
10:13 AM Deejay: hi
11:19 AM -!- #linuxcnc mode set to +v by ChanServ
11:49 AM perry_j1987: milling these holes sure is loud compared to drilling :P
11:50 AM perry_j1987: one nice thing about lathes... so quiet
12:06 PM CaptHindsight: A36 vs. 1018 Steel
12:08 PM CaptHindsight: do you find A36 a bit more difficult to machine?
12:19 PM perry_j1987: i've never had a problem with either
12:19 PM perry_j1987: (never done any machining with steel yet haha)
01:28 PM perry_j1987: hows everyone doing
01:29 PM jym: Yeah, it's quite in here lately, usually is during the summer
01:29 PM perry_j1987: you mean the guys venture outside away from the cnc machines when its nice out?
01:29 PM perry_j1987: thats not ok
01:30 PM jym: I guess so, those bastards!!!
01:30 PM Loetmichel: perry_j1987: or they take the CNCs with them
01:30 PM perry_j1987: somebody should call their mothers
01:30 PM jym: Loetmichel: Question... which coil do you use and at what wattage?
01:31 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12691&g2_imageViewsIndex=1 <- for a nice camping weekend with some 150 also dron fanatics for example ;)
01:31 PM Loetmichel: jym: aspire nautilus2 replacement coils at 1.2 and 1.6 ohms
01:31 PM perry_j1987: lol
01:31 PM Loetmichel: regular kanthal
01:31 PM jym: Loetmichel: so you do NOT use the sub ohm coil?
01:32 PM Loetmichel: i used the two 0.8 ohm coils that were delivered
01:32 PM Loetmichel: worked the same for me
01:32 PM jym: Loetmichel: what wattage?
01:32 PM Loetmichel: i only have the vapes set to 20W
01:33 PM jym: Loetmichel: I know it comes with one of each coil, just not sure which I would use (and why)
01:33 PM jym: Loetmichel: I do like VG more than PG
01:34 PM ve7it: jym, just say no to vapes!
01:34 PM jym: ve7it: and why is that?
01:34 PM Loetmichel: i have noticed that the nautilus coils tend to wick not enough juice for more than 20W if you do it sustained
01:34 PM ve7it: just giving ya a hard time!
01:34 PM jym: ve7it: carry on =)
01:34 PM Loetmichel: bursts are ok with more, but it starts to taste "burned" after 2-3 sec at 40W
01:36 PM jym: Loetmichel: OH that bites. My current drip tank has two coils and I'm using ss mesh instead of cotton wick
01:36 PM * Loetmichel mouth vapes. i dont like drip tanks, to inconvenient
01:37 PM Loetmichel: perry_j1987: i was milling more replacement parts for drones that weekend than i was being in the air with MY drone ;)
01:38 PM jym: Loetmichel: Well, that's why I'm looking for another setup, I just have a mech mod and drip tank right now, not a hip holster full of vape pens =)
01:38 PM perry_j1987: does that mean your not good at flying? :P
01:38 PM miss0r2: so.. my buds wedding present is complete: https://imgur.com/a/Kylf6eM hehe
01:38 PM Loetmichel: perry_j1987: for the OTHER 150 drone pilots
01:38 PM Loetmichel: not spare parts for MY drone
01:38 PM perry_j1987: ah heh
01:38 PM miss0r2: I ended up scrapping the idea of making my own woman template, did a final web search on the danish equivalent of craigs list, and found this beauty for next to nothing :)
01:39 PM Loetmichel: miss0r2: thats called a mannequin though, not a "woman template" ;)
01:39 PM jym: Loetmichel: you mobile cnc freak ;)
01:40 PM miss0r2: Loetmichel: Yeah, I know what THAT is called :) but I was going to cut out a woman template in 12mm plywood
01:40 PM perry_j1987: lol woman template
01:40 PM Loetmichel: perry_j1987: we had a guinnes record try that weekend IIRC. 130++ drones simultaneously in air... piloted, not on auto!
01:40 PM jym: miss0r after seeing that, and as a WEDDING gift (not a bachelor party gag), might I suggest origami / flower dollar bills?
01:40 PM Loetmichel: on a single soccer field ;)
01:41 PM perry_j1987: no wonder your mill was busy heh
01:41 PM miss0r2: jym: Thought about it.. decided this was the better way to go - no way they will ever forget :D
01:41 PM jym: miss0r or cover the undies in the money?
01:41 PM Loetmichel: perry_j1987: i desinged my own centerplate out of 3mm thick Carbon fibre
01:42 PM Loetmichel: that got taken on quite well in the community
01:42 PM miss0r2: jym: Meh... since the picture was taken, I moved the dollar bill decks from the front to the back, and filled the bra with more bills. also, using magnets, I added some "dropped" bills on the stand base
01:42 PM Loetmichel: it had the fame of being "indestructible"... so i had to do quite a few for my fellow pilots there
01:42 PM jym: miss0r lol
01:43 PM Tom_L: Loetmichel all the drones inside a gym?
01:43 PM miss0r2: I guess time will tell how many frowns this will generate :) I can live with whatever amount :D
01:43 PM Loetmichel: Tom_L: nope, it was a soccer field where we met
01:44 PM Tom_L: that would be a record to beat..
01:44 PM Loetmichel: look at the date of that picture
01:44 PM Loetmichel: 130 simultaneously flying drones WAS a record back then
01:47 PM jym: Loetmichel: how did you power your mobile cnc?
01:48 PM Loetmichel: there was a ton of extension cords and "baustromverteiler"
01:48 PM Loetmichel: hmmm
01:48 PM Loetmichel: wonder what the english word for that is...
01:48 PM jym: inverter?
01:49 PM Loetmichel: Worksite power dristribution boxes
01:49 PM FinboySlick: miss0r2: My main objection is that they're only 1$ bills. You cheaped out on that gift.
01:49 PM jym: ah
01:49 PM miss0r2: FinboySlick: Hey, i'm not made of money :)
01:49 PM Loetmichel: and yes, i had a 1500W APC UPS in the car because the extension cords werent THAT reliable
01:49 PM FinboySlick: No but the gift is!
01:50 PM miss0r2: FinboySlick: But to be fair, I should've gotten bigger bills, so I didn't have to keep two decks intact.. that looks strange
01:50 PM miss0r2: but nontheless.. :)
01:50 PM miss0r2: Anyway, I'm off. See you around
01:50 PM FinboySlick: miss0r2: It isn't real friendship under $50 notes.
01:51 PM miss0r2: FinboySlick: If thats the going rate, I'd struggle to even afford one friend :)
01:51 PM * miss0r2 is out
01:51 PM jym: miss0r see ya stripper boy
01:51 PM jym: boy*
01:52 PM Loetmichel: FinboySlick: maaan, you are pretty greedy, you know that?
01:56 PM FinboySlick: Loetmichel: I'm being progressive. Think of it like minimum-wage for friendship.
01:56 PM FinboySlick: Universal Basic Stipper.
01:56 PM jym: lmao
01:58 PM FinboySlick: jym: https://streamable.com/tgl0q I thought that was amusing.
01:58 PM FinboySlick: Figured it might be to you too.
01:59 PM FinboySlick: 88mm anime girl
01:59 PM FinboySlick: (as this is the shot from a Tiger 1 tank in the movie)
01:59 PM jym: FinboySlick: no anime pleasse.
02:00 PM FinboySlick: Only half, only half.
02:00 PM FinboySlick: You get Brad Pitt to make up for it in the second half.
02:00 PM jym: FinboySlick: It's anime, not much can make up for bad anime
02:05 PM perry_j1987: someone gave me a dremel 7700 cordless
02:05 PM perry_j1987: its actually pretty handy
02:06 PM perry_j1987: nice not having a cord
02:07 PM jym: perry_j1987: SET YOURSELF FREE, CUT ALL THE CORDS!!!!
02:08 PM perry_j1987: heh
02:08 PM perry_j1987: i would like a solar/wind powered shop some day
02:24 PM justan0theruser is now known as justanotheruser
03:37 PM Deejay: gn8
03:54 PM jym: perry_j1987: Then yu better move to the Mojave Desert or Antartica
04:00 PM chupacabra: What is everybodys favorite cam setup?
04:01 PM perry_j1987: jym or use it as excuse to not get any work done heh
04:01 PM jym: Never!!!
04:27 PM Nick001-Shop: Where are the G54-59 offsets stored?
04:28 PM JT-Shop: .var file
04:34 PM jym: NEVER EVER BUY "Wagan Tech" (Fremont company) products. Just had a brand new never opened inverter blow up before it was even turned on
04:36 PM andypugh: These things can happen. The real test is whether they send an immediate replacement.
04:36 PM jym: andypugh: No, had another one blow up too, just thought it was getting old. And they will not replace it because I can't find the receipt
04:37 PM jym: te cap blew on both of them
04:37 PM Nick001-Shop: lathe.var file? All of a sudden I have a ~4" error in Z0 location
04:41 PM andypugh: jym: OK then they suck.,
04:42 PM jym: andypugh: =) Just wanted to warn about the brand just in case
04:44 PM jym: andypugh: At least with HArbor Freight crap, you know what you are getting into and have 90 days to return it =)
04:46 PM jym: But... Now I have a nice aluminum enclosure to install the hour meter for the generator in =)
04:50 PM XXCoder: jym: wonder if that pre-blown one was returnee
04:52 PM pcw_mesa: Yeah, keep shipping it until it doesn't return...
04:56 PM jym: XXCoder: Sealed clam shell packaging, so nope
04:57 PM XXCoder: only way open is break?
04:57 PM XXCoder: can still be repacked at factory
04:57 PM jym: pcw_mesa: and sold at frys
05:00 PM jym: XXCoder: f that was the case, then that's why I giave a warning to everyone
05:00 PM XXCoder: indeed
05:01 PM XXCoder: utter qa failure on either case
05:01 PM jym: kinda hard to QA blown caps
05:02 PM jym: or will-blow-caps =)
05:02 PM XXCoder: easy actually for blown, it oesnt turn on or doesnt work lol
05:03 PM jym: plug into lighter, caps beign to charge, then POW
05:15 PM andypugh: plug in to lighter?
05:16 PM jym: andypugh: Cigar lighter socket in car (12VDC)
05:16 PM andypugh: Ah, right, that type of inverter.
05:17 PM jym: YEah, just a lil 140W job, for like recharging laptops on the road
05:17 PM andypugh: (Coming soon, to a pickup truck near you, 20kW 120V socket on the bed powered by the engine alternator)
05:17 PM jthornton: lol
05:18 PM jthornton: just short the laptop battery to the truck battery for an instance charge!\
05:18 PM andypugh: Not a joke, jthornton
05:18 PM jym: andypugh: The toyota hybrids (non US) actually have a 220VAC kit to power your home, and it's suppose to be the most effeciant generator there is
05:19 PM jym: it will even auto start the engine when the batteries are low
05:19 PM andypugh: This application was based on the observation of how many pickup trucks were spotted lugging a cement mixer + generator.
05:19 PM jthornton: our old Honda Civic hybrid would not start the car from the big battery
05:20 PM jym: jthornton: still doesn't to my knowledge
05:20 PM jym: which is strange that you still need a SLA battery for a hybris
05:21 PM jthornton: dunno about the new Honda Insight or not don't even know where the small battery is in it or the big battery
05:21 PM jthornton: it has fold down rear seats so it ain't behind the back seat like the old Civic
05:23 PM jym: jthornton: what hybrid do you have now?
05:24 PM jthornton: 2019 Honda Insight
05:40 PM andypugh: Inside my lathe apron I currenly have a horribly fiddly three-way terminal block, on the end of a wire, that the limit prox connects to.
05:40 PM andypugh: It’s unsatifactory.
05:41 PM andypugh: What I want there is a mating connector, with three pins, that is cage-clamp on at least one side.
05:41 PM andypugh: Does anyone konw of such a thing?
05:42 PM SpeedEvil: I suppose it's not sensible for me to suggest 3.5mm headphone plug/socket.
05:42 PM andypugh: I could probably use one of the smaller PCB pluggable headers. But then I am soldering wires and heat-shrink to PCB pins, which is workable.
05:43 PM andypugh: SpeedEvil: I looked at them, but they are not “field wirable” if and when a prex sensor fails. It needs solder.
05:43 PM andypugh: (prox sensor)
05:45 PM SpeedEvil: https://www.aliexpress.com/item/32814510907.html
05:46 PM SpeedEvil: decent high contact pressure 'chocolate block' type replacement
05:46 PM SpeedEvil: maybe in combination with.
05:46 PM andypugh: Too fiddly!
05:47 PM andypugh: I need to make this connection down a 20mm gap between a lathe saddle and apron.
05:47 PM SpeedEvil: I mean for handling the rewiring, rather than day-day plugging
05:48 PM andypugh: But, those are interesting: They are a clone of a Wago product that Wago don’t actually make: https://www.youtube.com/watch?v=OP86SxqP7I8
05:48 PM SpeedEvil: I was just about to link that.
05:48 PM SpeedEvil: :)
05:48 PM SpeedEvil: i have a bag of them on the boat.
05:49 PM andypugh: Are they salt resistant?
05:50 PM SpeedEvil: I have doubts.
05:50 PM SpeedEvil: Oh.
05:50 PM andypugh: My experience of boat electrics is “leave several feet of slack everywhere for re-termination”
05:50 PM SpeedEvil: I mean on the boat from china
05:50 PM andypugh: Ah!
05:53 PM andypugh: Most interesting cable on the boat was the one from the Windex on the top of the mast, down the mast. That’s a cable hanging 30m (100’) vertically in a tube with no intermediate support.
05:54 PM SpeedEvil: Properly terminated cable with a mechanical element I guess.
05:54 PM andypugh: And, of course, it flaps around as you sail.
05:54 PM andypugh: It didn’t appear to be anything special.
05:56 PM andypugh: The Windex did fail, and I offered to pop up the mast and have a look. So I was hoisted up 30m on a rope, and found that the windex arm was 2m (6’) long, and I was in a harness hard against the masthead pulley. I could _see_ the windex. But there was really no way to get any limb more than half-way there.
05:58 PM SpeedEvil: :)
05:58 PM SpeedEvil: just lean the boat over a bit.
05:58 PM Jymmm: andypugh: No kevlar stress relief line in the cable?
05:58 PM andypugh: Another time I went up half way to look at the steaming light. You know how you need three hands to operate a multimeter? Now try having to use one of the three to hold on to the mast to avoid swinging about like a pendulm (it was quite choppy, this was in the middle of the Pacific)
05:58 PM SpeedEvil: ^What I was meaning with 'mechanical'
05:59 PM andypugh: SpeedEvil: Ah, are you referring to this approach? https://www.youtube.com/watch?v=y4loB_UGxw8
06:01 PM mmachines: that aliexpress page has DIN rail mounted wago style connectors
06:01 PM mmachines: hadn't seen them before, not sure how useful it is if you mount on the DIN rail it's easy enough to use the screwdriver
06:02 PM SpeedEvil: https://www.youtube.com/watch?v=kiv0fxFcV3I - I was thinking of originally
06:02 PM SpeedEvil: How to Get An 85 Ft Mast Under A 65 Ft Bridge
06:06 PM andypugh: Pah! They should have done it under sail.
06:07 PM SpeedEvil: :)
06:08 PM SpeedEvil: If you lash two boats together by the masts, is it a catamaran?
06:09 PM jym: Looks like he's done that before, but how???
06:11 PM andypugh: With a bit of maths, and markers on the halyards, you can be very confident that when the weights are touching the water you will fit under the bridge.
06:11 PM jym: andypugh: As far as you 30m of free hanging cable... fiber optic cable has a kevlar strand to prevent stretching. Could it have soemthing like that?
06:11 PM andypugh: Though, of course, a fair bit of work with the tide-tables will also be required.
06:12 PM andypugh: jym: It could. It didn’t.
06:12 PM jym: andypugh: No I mean how did he actually tilt the boat up/back once the weights were in place?
06:12 PM jym: andypugh: Ah, heh
06:13 PM andypugh: jym: He pulled the weights back inboard with another bit of string.
06:13 PM jym: and literally swung them out to begin the tilting?
06:14 PM andypugh: The really clever part is actually using weights that float (or nearly float) so that you don’t explore the too-far instability.
06:15 PM andypugh: I imagine that to start the manouvre they simply lifted the weights up off the deck and steered out from under them.
06:16 PM jym: Ah gotcha
06:18 PM jym: So, how many times do you practice that before doing the real thing =)
06:19 PM jym: and is "Here, hold my beer..." part of the process????
06:20 PM andypugh: It is a pretty easy thing to try out, I guess. Just do it somwhere where the bridge isn’t
06:20 PM jym: Sure, but you only got ONE shot to get it right =)
06:21 PM jym: You know what boat stands for.... BUCK OUT ANOTHER THOU$AND =)
06:21 PM andypugh: You can use a similar approach when your keel is stuck on the bottom, though you don’t have the “steer out from under” there.
06:21 PM andypugh: But standing the crew on the boom and swinging that out...
06:22 PM SpeedEvil: Also, you can try it out with the mast over a beach
06:22 PM SpeedEvil: so it can't go too far
06:23 PM andypugh: once the weights hit the water the system changes enormously.
06:24 PM andypugh: More impressed by this :-) https://www.youtube.com/watch?v=7ZmJtYaUTa0
06:32 PM jym: the bridge was cool
06:35 PM andypugh: Danny Macaskill does more impressive stuff, but on a bike built for the job. Thouigh as a skier I love wgan Candine Thovex does, have you seen this? https://www.youtube.com/watch?v=R1NagZN2kjY
07:02 PM jym: Every way to cook an egg...  https://www.youtube.com/watch?v=qWAagS_MANg
07:05 PM XXCoder: apparently reserant AW is now 100 years old
07:05 PM XXCoder: got annv. mug lol
07:10 PM jym: Is A&W still in business?
07:11 PM XXCoder: yeah
07:11 PM XXCoder: few of em left but still going
07:11 PM jym: Cool, they have good burgers
07:12 PM XXCoder: i want to go to fuddrickers
07:12 PM XXCoder: whatever its spelled, looks vaguely like a curse
07:12 PM jym: But I thought &W was way over 100yo, more like 120
07:12 PM jym: fudruckers
07:12 PM XXCoder: https://www.fuddruckers.com/
07:14 PM jym: I"m just not all impressed by them, or even Five Guys
07:14 PM XXCoder: i miss rice junkie
07:14 PM XXCoder: but way too hard to go there
07:14 PM jym: I used to love In and out, but they changed long ago
07:15 PM jym: (around here) surprisingly the best place to get a burger is the hospital cafeteria and cheap too
07:16 PM SpeedEvil: jym: do they cover 'place in the plastic egg tray at 120C in the oven for one hour?'
07:16 PM jym: SpeedEvil: in over yes, not in plastic though =)
07:16 PM XXCoder: in n out was decent
07:16 PM andypugh: There is 45 minutes in a sous-vide bath
07:16 PM jym: XXCoder: Was, over like 15 years ago
07:16 PM XXCoder: then they heavily donated to anti-lgbt and stuff so yeah no more
07:17 PM SpeedEvil: jym: the plastic is very deformed at the end, but does not stick to the eggs, so it's fine.
07:17 PM andypugh: I am waiting to see if “virgin boy eggs” feature.
07:17 PM jym: XXCoder: They've always been a theology organization, look on the bottom of every soda cup =)
07:17 PM XXCoder: I know.
07:17 PM XXCoder: i dont care
07:17 PM jym: SpeedEvil: lol
07:17 PM XXCoder: but when they support rights supression groups thats when I cut them off
07:17 PM SpeedEvil: No water, no tray, no effort.
07:17 PM jym: XXCoder: I didn't know they were anti-lgbt though
07:19 PM jym: XXCoder: Just another reason not to even bother with them anymore. and their fries kinda suck
07:19 PM XXCoder: i never did have courage to order animal style
07:19 PM jym: XXCoder: animal burger or animal fries?
07:19 PM XXCoder: both
07:20 PM jym: animal buger I liked, animals fries were blah
07:20 PM XXCoder: ironically they also pissed off gop people by donating to big business supporting democrats also
07:20 PM jym: lol
07:20 PM roycroft: most religions make a large part of their living by hating on some group of people who are not exactly like themselves
07:20 PM XXCoder: its olvious they support anyone who would "strach back" back
07:20 PM roycroft: so any time you encounter a "faith based" company/group/whatever you can be pretty sure they're gonna do some hating
07:21 PM XXCoder: roy i thought in n out was exception
07:21 PM XXCoder: maybe they was, indeed, was. but have changed.
07:22 PM jym: Turtle's first strawberry... https://www.youtube.com/watch?v=CsxSXVbNL0Q
07:22 PM roycroft: so i was just cutting a single point thread, which i haven't done in a while
07:22 PM roycroft: please to sanity check me
07:22 PM roycroft: i had the compound set to 29.5 degrees
07:23 PM roycroft: i made sure the cutter was ground to exactly a 60 degree included angle, and was exactly perpendicular to the work
07:23 PM roycroft: i touched off
07:23 PM roycroft: set the cross slide and compound to zero
07:23 PM roycroft: then started cutting by turning the compound in 0.010" at a time
07:23 PM XXCoder: jym: lol literally bigger than it
07:24 PM roycroft: the thread was moving to the left and i could see the steps in it, so it was kind of "smeared"
07:24 PM jym: XXCoder: by DOUBLE too
07:24 PM roycroft: i.e. each pass was to the left of the previous
07:24 PM roycroft: i stopped turning the compound and started just using the cross slide and the thread cleaned up
07:24 PM XXCoder: "* Please note: Russian tortoises like me should generally not eat fruits, as our guts are not equipped to handle the sugar. I was only allowed to have a few tiny nibbles of this strawberry as a special treat before Mom took the strawberry away."
07:25 PM jym: XXCoder: Tease
07:25 PM roycroft: but unless i'm on crack or otherwise demented, i've always used the compound to cut threads
07:26 PM andypugh: roycroft: Wrong 29.5 degrees maybe?
07:26 PM roycroft: the cutter is moving towards the spindle as i advance it
07:26 PM roycroft: so i think it's the right one
07:27 PM andypugh: Where is zero>
07:27 PM roycroft: you're not saying i'm an idiot so that means that it should have worked
07:27 PM roycroft: which zero?
07:27 PM andypugh: Exactly
07:27 PM roycroft: i'm cutting from right to left
07:27 PM roycroft: so i set the cross slide and compound both to zero
07:27 PM roycroft: move to the right
07:27 PM roycroft: advance the compound
07:27 PM roycroft: make a pass
07:27 PM roycroft: back out the cross slide
07:27 PM roycroft: move to the right
07:27 PM roycroft: dial the cross slide back in to its zero
07:27 PM roycroft: advance the compound
07:28 PM roycroft: make another pass
07:28 PM roycroft: lather, rinse, repeat
07:28 PM andypugh: If zero is “no taper” then you need 60.5 on the degree marks
07:28 PM roycroft: oh, i see what you mean
07:28 PM roycroft: now i'll have to check to see where zero is
07:29 PM roycroft: i thought it was no taper
07:29 PM roycroft: the thread works ok, but it's ugly
07:29 PM roycroft: fortunately i have more ss rod, so i can make a not-so-ugly one when i figure out what i did wrong
07:29 PM roycroft: i used to cut threads like this frequently, but it's been months
07:29 PM andypugh: Does the compound look to be at about a sort of thread angle?
07:30 PM roycroft: yes
07:30 PM roycroft: it looks like it's half the angle
07:30 PM roycroft: half the included angle
07:30 PM roycroft: like if i had a mirrored compound it would form a proper thread groove
07:30 PM andypugh: OK, I was just speculating what could possibly go wrong in a moment of weakness :-)
07:31 PM roycroft: i'm all for thinking this is some kind of moment of weakness
07:31 PM andypugh: Were you using the threading dial?
07:31 PM roycroft: i'm totally blaming it on operator error until proven otherwise
07:31 PM roycroft: yes
07:31 PM roycroft: and it was a 1/2"-13 thread
07:31 PM andypugh: Maybe the 127 wheel is still fitted from a previous metric thread?
07:31 PM roycroft: i was indexing on the same point of the dial every time
07:32 PM roycroft: but it cut much more, if not entirely, consistently when i stopped advancing the compound
07:32 PM roycroft: and started advancing the cross slide
07:32 PM andypugh: Good point.
07:32 PM roycroft: if it's not indexing correctly the problem would not go away when i advanced the other
07:32 PM roycroft: it might change
07:32 PM roycroft: but it would not go away
07:32 PM andypugh: But maybe that was enough to mask a very slight offset?
07:33 PM roycroft: the only thing i've checked so far is to ensure that the thread dial is engaging well, so it's not slipping
07:33 PM andypugh: I think it might be worth looking for a funny in the gear teain.
07:34 PM andypugh: (gear train)
07:34 PM roycroft: i think what i should do is insert another piece of rod, put some blue layout dye on it, and do repeated scratch cuts
07:34 PM roycroft: see if it varies without making any changes
07:34 PM roycroft: if that's the case i can start blaming the lathe
07:34 PM andypugh: Yes, that would show up an extra tooth in the change wheels
07:34 PM roycroft: and yeah, taking a look at the gear train would be a good idea
07:35 PM roycroft: the half nut does not engage as easily as i should like
07:35 PM roycroft: but it does engage, and i'm 100% confident i'm engaging it consistently at the same point on the thread dial
07:36 PM roycroft: this lathe has a quick change gear box, so i don't change the gears around very often, because i don't need to
07:37 PM roycroft: which makes it unlikely that i changed them incorrectly
07:37 PM roycroft: and when i did my initial scratch pass the thread pitch was spot on
07:38 PM roycroft: something that my machining instructors deeply engrained in me was to always make a scratch pass and verify with a thread pitch gauge before cutting the thread
07:38 PM roycroft: it did not take much convincing for me
07:39 PM roycroft: but i'm sure they deal with young whippesnappers all the time who are cocky and infallible
07:39 PM roycroft: so they really hammer that home hard
07:40 PM roycroft: to the point that i think i'm physically incapable of cutting a thread without verifying the thread pitch first
07:40 PM roycroft: i just don't think my hand can pull the lever to engage the half nut if i haven't done that yet
07:41 PM roycroft: i'll go dykem a rod and see if multiple scratch passes move around - that will be a good next test
07:41 PM andypugh: I just tell LinuxCNC what I want, and a thread happens.
07:41 PM roycroft: some day i may do that
07:41 PM roycroft: but not today
07:41 PM roycroft: thanks for the sanity check
07:56 PM sync: andypugh: the more interesting tidbit is, that I averaged 98kmh over the last 6500km and only used 7.9l/100km in that time
07:56 PM mmachines: I guess it's not possible to somehow pass an argument to an MDI command in linuxcnc hal?
07:56 PM andypugh: l/100 means nothing to me, and furthermore is a stupid unit :-)
07:57 PM mmachines: say I have in the .ini: MDI_COMMAND = M113
07:57 PM andypugh: mmachines: No, it is entirely possible
07:57 PM mmachines: and M113 is a bash script
07:57 PM andypugh: You can pass P and Q as $1 and $2 (IIRC)
07:58 PM andypugh: http://linuxcnc.org/docs/2.7/html/gcode/m-code.html#mcode:m100-m199
07:58 PM andypugh: There are even examples there
07:58 PM mmachines: hmm ok thanks but I'm thinking of say with a net statement
07:59 PM andypugh: Huh? How can you concieve of netting an M-code?
08:00 PM andypugh: You could make the bash script “setp my.hal.pin $1” I suppose
08:00 PM andypugh: Can we back up a level, what do you hope to achieve?
08:01 PM mmachines: OK just hacking on my config trying to think of a simpler way to manage all of the MDI commands
08:01 PM andypugh: If you want to set a HAL pin value from G-code then look at M67
08:02 PM mmachines: currently I connect separate pins to separate MDI commands with say : net mynet halui.mdi-command-NN mypin
08:03 PM mmachines: wondering if I could somehow eliminate separate MDI commands and have say a single script that accepts arguments to decide what to do
08:03 PM andypugh: Yes. You can do that.
08:04 PM andypugh: bash doing magic and halcmd is one pay. Python and the LinuxCNC Python interface allows still more.
08:05 PM perry_j1987: hey guys, what endmill would you suggest for brass, 1/8 as i. need to bore some 5 or 6mm holes in about 20mm thick brass bars
08:06 PM sync: andypugh: about 30mpg
08:06 PM mmachines: OK interesting. I am using the Python interface for a few things
08:06 PM andypugh: Possibly HSS as it tends to be sharper. (I have never cut myself on a carbide milling cutter). Brass likes a very sharp cutter.
08:06 PM mmachines: but don't currently see a way to connect say multiple pyvcp pins to a single MDI command
08:07 PM andypugh: Switch ti GladeVCP and an embedded Python handler?
08:08 PM perry_j1987: HSS prob better for less rigid machines too not as likely to shatter if you look at it wrong
08:08 PM perry_j1987: how many flute
08:09 PM mmachines: ok thanks I will look into it maybe GladeVCP or Qt at some point. I'm using default AXIS and pyvcp embedded panel and floating panels now
08:09 PM andypugh: Flutes probably depends on your spindle speed and torque
08:09 PM perry_j1987: its one of those 6040 cnc 2.2kw spindles
08:09 PM perry_j1987: 24,000 rpm max
08:09 PM andypugh: In that case,1 or two flutes.
08:09 PM jym: andypugh: Heh, ask jthornton about the cutter I turned him on to =)
08:12 PM jym: andypugh: carbide c-flute cutter design for cutting plastics
08:13 PM perry_j1987: all these cutters with longer flutes just say good for plastics and woods heh
08:14 PM jym: perry_j1987: Uh no, Theres are specifically made for plastics and work very well
08:15 PM perry_j1987: im trying to find one for brass
08:15 PM jym: engraving?
08:16 PM jym: perry_j1987: engraving brass or cutting brass?
08:16 PM perry_j1987: helical boring some holes in brass
08:16 PM perry_j1987: my spindle is too fast for drilling
08:16 PM jym: ah
08:16 PM jym: no clue
08:44 PM perry_j1987: https://littlemachineshop.com/products/product_view.php?ProductID=3990&category=1387807683 this one looks pretty good
08:45 PM XXCoder: interesting
08:47 PM perry_j1987: looks like much better motor and more rigid frame than the other ones
08:52 PM Tom_L: i was looking at a 700w one but they want too much for it
08:52 PM Tom_L: spindle motor that is
08:53 PM Tom_L: i'd want more range than that one has
08:54 PM perry_j1987: treadmill motor then? :)
08:55 PM Tom_L: i dunno
08:56 PM XXCoder: isnt there 1000w china solutions?
08:56 PM XXCoder: 1000w * china = around 800w
09:01 PM perry_j1987: the other mini mills are 350w brushed
09:01 PM Tom_L: XXCoder most if not all are high speed no torque
09:01 PM XXCoder: true
09:01 PM jym: perry_j1987: https://www.grizzly.com/products/Grizzly-Mill-Drill/G0758
09:01 PM XXCoder: belt torque tho?
09:01 PM Tom_L: then i'd have the same problem perry_j1987 has
09:01 PM Tom_L: i'm not looking for problems
09:01 PM jym: I wish dremel cotoff wheels weren't so fragilee
09:01 PM roycroft: so if anyone is interested, i think i have solved my problem with the lathe
09:01 PM XXCoder: thought he had issue of spindle being too fast?
09:01 PM roycroft: the index dial on the cross slide was loose, and was slipping when i backed the cutter off
09:02 PM roycroft: so the "fix" is going to be a new shaft, or turning the existing one down until it's concentric again
09:03 PM roycroft: i might be able to do that by removing the shaft, which meands dismantling the cross slide
09:03 PM roycroft: putting it between centers
09:03 PM roycroft: and maybe using some emory cloth to make it round again
09:03 PM roycroft: or mounting some kind of tool holder on the apron where the cross slide normally lives
09:03 PM roycroft: or finding someone else with a lathe to do it for me or leet me use their lathe
09:06 PM roycroft: if i had set the compound to exactly 30 degrees, instead of 29-1/2 degrees, i might not have seen the stepping/smearing
09:44 PM Vitran: Looks like the timing belt pulley on my encoder is a little worn out. https://i.imgur.com/VkFtVL0.jpg
09:45 PM Vitran: But the belt looks good https://i.imgur.com/5CfNXyk.jpg https://i.imgur.com/O5Yb4Lm.jpg https://i.imgur.com/uiXFTnB.jpg
09:46 PM Vitran: I asked Hardinge how much for a new pulley. $1460 usd, and a new shaft is required. $1045 for that. I asked and nope, they did not misplace the decimal place.
09:46 PM Tom_L: of course
09:47 PM Vitran: it is an XL belt, 50 tooth, 3/8" bore. Needs some custom machining to make it thinner
09:47 PM Vitran: Would be a shame if someone had a lathe that could do that instead of buying a new one
09:48 PM Tom_L: i'm sure someone here probably would
09:48 PM Vitran: I jest. I can still use the old pulley. I just find it funny Hardinge would charge that much
09:48 PM Tom_L: that pulley looks pretty rough
09:49 PM Vitran: The old pulley works. It was working fine until I tightened the belt
09:49 PM Vitran: The pulley had flat walls. The belt wore the flanges onto the pulley
09:50 PM Vitran: Problem is, by tightening it the diameter of the pulley is not the same as the spindle's gear. I was trying to figure out why the rpm on the spindle was so wonky
09:51 PM Vitran: Spindle RPM chart. I thought it was my spindle motor, a shunt motor, was bad. I think it was just jumping when the peak or base of the timing belt hit the top or base of a pocket. https://i.imgur.com/7PAzTyX.jpg
10:18 PM roycroft: vitran must not know hardinge very well if a $1.5k quote for that part seems out of line coming from them
10:18 PM Vitran: Eh,
10:19 PM Vitran: I found the same gear for $33 from Toronto Pulley
10:19 PM roycroft: i'm not saying it's out of line in the real world
10:19 PM roycroft: i'm saying it should not be a surprise that hardinge charge that much
10:19 PM roycroft: they are very high on parts
10:19 PM roycroft: very very high
10:20 PM Vitran: Their other parts are not that much. Collets are ~$104 each, which, compared to ebay prices, isn't insane
10:21 PM Vitran: Ebay 16C collets are not going below $50 very often
10:21 PM Vitran: And, being in Canada and near a university, half the parts are metric and half are imperial and 16C collets have a 0.004" range. FML for how many I will end up getting
10:21 PM roycroft: collets are not parts
10:23 PM roycroft: a lot of lathe manufacturers' parts are really expensive, but hardinge are definitely on the high side
10:23 PM roycroft: even import lathes like jet/enco/grizzly have some very expensive parts
10:23 PM Tom_L: which side of canada?
10:24 PM Vitran: Ontario
10:24 PM * roycroft would guess toronto or southwest ontario
10:24 PM Vitran: Stoney Creek, near Toronto
10:24 PM roycroft: where all the car parts are made for the us manufacturers
10:24 PM roycroft: half in american standard units and half metric
10:25 PM Vitran: I am using an ER32 collet block in the spindle to hold most of my parts now
10:25 PM Vitran: if it is on orders of <5.
10:25 PM roycroft: i just read, btw that myanmar are converting to metric finally
10:26 PM roycroft: that leaves the usa and tunisia as the only two countries in the world that aren't metric
10:26 PM roycroft: er, liberia, not tunisia
10:29 PM roycroft: and even liberia are starting a slow transition to si units
10:29 PM roycroft: petrol is sold by the litre there now
10:29 PM Vitran: I thought the British were a little imperial
10:30 PM roycroft: kind of like you are
10:30 PM roycroft: officially metric, but somewhat imperial on the street
10:31 PM roycroft: the us adopted the metric system in the 1860s
10:31 PM roycroft: and then again in the 1970s
10:31 PM roycroft: one of these centuries we'll finish converting over
10:32 PM Vitran: Try finding a Roberson screwdriver in Alabama. They like staying stuck
10:32 PM roycroft: they call them "square drive"
10:32 PM roycroft: and yes, are all but impossible to find in parts of this country
10:33 PM roycroft: but electricians use robertson screws quite commonly im most of the us
10:34 PM Vitran: I heard but cant verify that a company near us needed to ship Roberston screwdrivers with their machines for the electricians in some states.
10:35 PM roycroft: personally i don't use them much
10:35 PM roycroft: i don't like the way the head looks
10:35 PM roycroft: so if it's a fastener that is going to show i don't use it
10:35 PM roycroft: for hidden fasteners i prefer torx to robertson
10:35 PM roycroft: but before torx became common i used robertson a lot more
10:35 PM Vitran: I feel it doesn't strip as much compared to a hex
10:37 PM roycroft: i use slotted or phillips head screws for furniture/general woodworking, and for things that are visible in the house
10:37 PM roycroft: for machinery i usually use hex drive fasteners
10:38 PM roycroft: i'm rather detail oriented - i almost always soldier any fasteners that will show, no matter what the application
10:38 PM roycroft: it's a way for me to channel my anal retentive energy in a non-destructive way :)
10:40 PM Vitran: I had a friend help me do some wiring on the lathe. To connect a frayed wire to a round hole he would get a furrel, crimp it to the wire, add hot glue to the opening of the crimp, then add heatshrink to the wire/furrel so that vibration wouldn't break the connection
10:41 PM Vitran: Little did he know that when he crimped it he crimped onto the wire insulation and cut some of the wires in the process underneath all that glue. Also, this was on the front control plate of the lathe and the wires were ziptied to anchors so not in a place of vubration
10:41 PM Vitran: But he had fun doing it
10:49 PM Vitran: I am also making a bar pusher for my lathe Doesn't seem that hard so far. I used my dad's old lathe. Apparently this was a first time for someone using a secondary rest. I need 27" of travel on a bed that had only 19" of travel.
10:50 PM Vitran: https://imgur.com/0ptsdze https://i.imgur.com/Zcgn6Hl.jpg https://i.imgur.com/x5nMkyj.jpg https://i.imgur.com/kTQ2sAi.jpg https://i.imgur.com/DAr1uyI.jpg https://i.imgur.com/ntzclCV.jpg
10:51 PM Vitran: I then make a cylinder head to go inside the pipe. Add air pressure at the end and it will push a bar through the collet.
10:51 PM Vitran: I based it off of this guy's video https://www.youtube.com/watch?v=RkN7ke9f_ys
10:52 PM Vitran: I was finishing up doing the internal 1-11/16" of the cap that goes on the end when the spindle synchronization stopped working.
