12:02 AM veegee: Found another forklift that looks much newer: https://www.kijiji.ca/v-heavy-equipment-machinery/mississauga-peel-region/hyster-forklift-runs-great/1498388577
12:07 AM veegee: Twice the cost of the first one, same model
12:07 AM veegee: Not sure if it's worth purchasing.
12:07 AM veegee: If I were to sell it again, would people care that it's newer? Not sure how it works for equipment like this
12:07 AM CaptHindsight: veegee: yeah, they want newer and lower hours
12:09 AM CaptHindsight: and hydraulic cylinder seals
12:09 AM CaptHindsight: Hyster is a good brand
12:16 AM CaptHindsight: Hyster / Yale
12:16 AM CaptHindsight: engine rebuilds and swaps are no big deal to me, since I can do all the work
12:16 AM CaptHindsight: but to the avg user, they want to just run it and maybe change the oil
12:22 AM skunkworks: pcw_mesa: but the error is only about 4 encoder counts at its peak
12:22 AM skunkworks: each encoder count is about .000019 and the peak error is only .00008ish
12:23 AM skunkworks: (which seems crazy to me)
12:25 AM skunkworks: CaptHindsight: we have a hyster..
12:35 AM veegee: Any thoughts on the pricing? Would be much appreciated
12:35 AM veegee: Thinking about buying it tomorrow
12:43 AM CaptHindsight: veegee: that is a good deal
12:44 AM CaptHindsight: as long as it works
12:44 AM CaptHindsight: or needs only something minor
12:44 AM CaptHindsight: look for leaks
12:45 AM CaptHindsight: no rod knocks or funny noises from the engine or transmission
01:01 AM Deejay: moin
01:16 AM Loetmichel: mornin'
01:19 AM Loetmichel: BTW: i did it and bought that 2004 E46 BMW 318i convertible... slight problem: the seller gave me the title, but forgot the last "TUEV" report. IN germany you need that to register a car and get new license plates. Also its a TON of work. That was to be expected though, its only 2950 eur after all.
01:27 AM CaptHindsight: Loetmichel: how often do you change cars?
01:37 AM Loetmichel: i didnt change my car
01:37 AM Loetmichel: i bought another one ;)
01:37 AM Loetmichel: for the summer ;)
01:47 AM CaptHindsight: ah
02:38 AM veegee: CaptHindsight thanks, going to buy it tomorrow.
02:47 AM pink_vampire: Tom_L: COOL! do you have any thermal paste or something between the motor and the coil?
03:20 AM * Loetmichel just has a bit of nostalgia... just pulling a few wires and mount a couple outlets to get our delivery desk laptop powered. MAAN is my sparky-fu rusty after 20 years no use ;)
05:14 AM JT-Cave: morning
05:14 AM XXCoder: yo
06:43 AM Tom_L: morning
06:44 AM Tom_L: pink_vampire, no
06:44 AM pink_vampire: so how it is transfer the heat?
06:44 AM pink_vampire: Tom_L: ^
06:44 AM Tom_L: quite well
06:45 AM Tom_L: it's a snug fit
06:45 AM JT-Cave: what are you making
06:46 AM Tom_L: https://www.youtube.com/watch?v=g0OLIth_cOI&feature=youtu.be
06:46 AM pink_vampire: PCB for vintage computer
06:47 AM Tom_L: nothing. she just noticed the coil on the motor
06:47 AM JT-Cave: ah
06:47 AM Tom_L: ^^ pi test.
06:49 AM JT-Cave: ah the copper tubing coil
06:53 AM Tom_L: nice last couple days here
06:56 AM pink_vampire: instead of drilling I'm doing 3mm pockets with 0.8mm endmill
07:00 AM pink_vampire: using*
07:28 AM Loetmichel: soo, aaand ANOTHER 700eur gone... Car registration service and insurance for a year... maan the OF registration bureay is nuts... called them" cant do online registration because of no internet passport". Their response: "then give it to a registration service, we dont to appointments for private persons at the moment... 50 eur extra just because corona :-(
07:42 AM miss0r: I have, apparently, lost an entire ER11 set... Fsck !
07:42 AM miss0r: I need to clean in here
07:43 AM miss0r: knowing it is in here *somewhere* is a poor consolation when I need it *NOW* ! :)
07:45 AM pink_vampire: miss0r: next time you need to use ER40
07:45 AM miss0r: yeah.. alot harder to loose :) But at the moment I am trying to grip a 1mm drill with a drillchuck that does not go lower than 3mm *sigh*
07:51 AM pink_vampire: do you have a pin vise?
08:32 AM miss0r: pink_vampire: I Don't even know what that is :)
08:33 AM miss0r: Do anyone in here have experience milling threads?
08:33 AM JT-Cave: Tom_L, does
08:34 AM miss0r: Tom_L: You around? I'm experiencing some funny issues tryig to mill an internal thread in a blind hole.
08:35 AM miss0r: I *think* I might have gotten some theory wrong. Should I not be able to halt all axis movements at any given point and move the still rotating tool towards the center of the hole without wrecking the formed thread?
08:35 AM JT-Cave: are you programming it by hand?
08:36 AM JT-Cave: you would think so but I arc out of the thread with my thread calculator
08:36 AM miss0r: no.. err.. somewhere in the middle of automatic and manual. I'm generating the code in mastercam, which is basically just doing a helical bore at the same pitch as the thread
08:37 AM miss0r: does that arc still move down in z/follow the pitch?
08:37 AM JT-Cave: yes
08:38 AM JT-Cave: breakfast time here
08:40 AM miss0r: hmm
08:40 AM miss0r: I just don't understand why that would be nessesary
08:40 AM miss0r: On the other hand I am wrecking parts at the moment. I just can't wrap my head around why that should be done..
08:40 AM miss0r: also, the design does not allow for me to exit in that way
08:41 AM miss0r: I am already 0.25mm from the bottom of the bore
08:43 AM miss0r: hmm.. This might be a clearance issue actualy
09:58 AM pink_vampire: miss0r: I did rigid tapping on my mill
10:02 AM skunkworks: pink_vampire: cool!
10:02 AM skunkworks: https://youtu.be/GrzJKXBsXvM
10:08 AM pink_vampire: skunkworks: nice lathe!
10:30 AM jymmmm: good morning
11:10 AM Loetmichel: soo, got our delivery intake "desk" PC done. installed some outlets for the PSU, milled an aluminium wall mount for the dell notebook and the barcode reader, installed it all... now boss has to get barcode-ready software ;)
11:10 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17818&g2_imageViewsIndex=1
11:20 AM skunkworks: heh - at 150ipm - servos are spinning at 3750 rpm
11:39 AM sync: yeah, in one of the handling units I have I spin the servo to about 6krpm
11:51 AM Tom_L: miss0r, i initially wrote my macro to do a linear move back to the center but changed it to an arc which makes it a bit smoother
11:51 AM miss0r: Tom_L: Impressive timing. I have been gone since 5 minutes after I wrote the questuin till now. I literally just walked in the door
11:52 AM miss0r: But tell me: Should it make a difference? other than a nicer "outlet" of the thread form
11:55 AM Tom_L: gimme a sec. just walked in
11:58 AM Tom_L: no it shouldn't matter
11:59 AM Tom_L: even if you have a linear leadout it's not gonna stop that much to notice anyway
12:01 PM Tom_L: i think it's more 'correct' to have the arc leadout back to center
12:01 PM miss0r: yeah BUT :)
12:01 PM miss0r: that arch then *must* follow the same pitch until it has cleared the threadform
12:01 PM miss0r: and I've no more depth in this bore to spare
12:01 PM Tom_L: of course
12:02 PM miss0r: which is the entire reason I've decided to mill this thread
12:02 PM miss0r: :)
12:02 PM miss0r: (Haven't tried it before today)
12:02 PM Tom_L: it's such a short area i doubt it would be noticeable either way
12:02 PM miss0r: indeed.
12:02 PM miss0r: What I think happened earlier is I ran out of clearance
12:03 PM miss0r: it would seem the mill decided to stop moving down during the last 1/4 turn or something like that.
12:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent.jpg
12:03 PM miss0r: I can clearly see that it would not have been able to move down further, yet theres no "smearing" marks at the bottom of the bore..
12:03 PM Tom_L: that's 3 pass
12:03 PM miss0r: indeed. I'm doing this in one go..
12:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin.jpg
12:04 PM Tom_L: both internal and external
12:04 PM miss0r: its a M65x3.5, which translates to a 2.0mm stepover on a 19mm shank.. its not bad
12:04 PM Tom_L: i'm sure one pass is fine, i just don't push it on my mill
12:05 PM miss0r: hmm... I will get back to you on this.. :) Are you around later, should I run into other questions?
12:05 PM miss0r: What mill are you running?
12:05 PM Tom_L: the one i made
12:05 PM * miss0r 's memory is poor at best
12:05 PM miss0r: I'm sure a picture will refresh my memory for me :)
12:06 PM Tom_L: https://www.youtube.com/watch?v=g0OLIth_cOI
12:06 PM miss0r: oh, by the way: I ended up downloading your entire IRC log and searched for the data that I needed on a linux box.
12:07 PM miss0r: Indeed. I remember it now
12:07 PM miss0r: I just can't remember what it is I was interrested enough to know that I scripted a downloader to get it all from your site...
12:07 PM Tom_L: heh
12:08 PM Tom_L: i had more i think but either lost them or they're on a hdd i'm not using right now
12:08 PM miss0r: meh.. back to the lathe to make a few blanks to accept the thread. Thanks for your time
01:24 PM CaptHindsight: skunkworks: ha Wi reopened? Was going to pop up for supplies
01:24 PM CaptHindsight: ha/has
01:35 PM bmbbsr: Hi From a Sunny Day in Germany tomorrow is Holiday :-)
01:35 PM bmbbsr: pcw_home, Are You Online Sir
01:36 PM bmbbsr: pcw_mesa, Sir are you here in the IRC Chat
01:36 PM pcw_home: Yes
01:36 PM bmbbsr: pcw_home, Die the German Defect 7i76e arrive
01:37 PM bmbbsr: Principal dident get some info until now
01:38 PM bmbbsr: pcw_home, you know the part with the Solder under the pins
01:39 PM pcw_home: Yes I got the card, it looks like someone removed/replaced the Ethernet Jack
01:39 PM bmbbsr: NO
01:39 PM bmbbsr: i tryed also to remove this as i removed the LED
01:39 PM pcw_home: the fault is that the Ethernet chip has been damaged somehow
01:40 PM bmbbsr: As i told you in the mail i dident know if they powerd it
01:40 PM Rab: CaptHindsight, I ended up with both single- and dual-serial variants of the CH382L 3250 card. The vendor sent the correct version and didn't want the old one back. All ports were recognized by andy's RTAI kernel, and they all worked fine with my parallel BoB.
01:42 PM CaptHindsight: Rab: the kernel devs backported all known variants to 4.something
01:42 PM Rab: The serial ports are recognized but not working on the dual-port variant, so that's kinda strange...but I really only wanted the parport function. I guess I'll undertake to update the WCH wiki when I'm convinced I haven't missed anything.
01:42 PM CaptHindsight: good to know that there are no odd new versions out there .... yet
01:43 PM Rab: Heh, wait two weeks.
01:43 PM pcw_home: (3.3V --> GND short)
01:43 PM bmbbsr: pcw_home, In the after Thinking i shoudent have tryed to fix it as you told me to do ,Send it back as it has been deliverd
01:44 PM CaptHindsight: Rab: I think that there are 2 pin strap resistors to set the PCI id, the Chinese data sheet has the info
01:44 PM pcw_home: Looks like the Ethernet got connected to something bad
01:45 PM bmbbsr: I dident power it at all as i did see the shortige at first look
01:45 PM Rab: CaptHindsight, yeah, there is some info on the wiki.
01:46 PM Rab: I also have both cards installed, since I had two free single-lane slots. So three parports!
01:46 PM CaptHindsight: Rab: just be careful, some people get mad at you for using "old ports" :)
01:47 PM bmbbsr: pcw_home, Do yiou think ther is a change of replacment,under this surcomstances
01:48 PM CaptHindsight: I've been seeing more and more of this on various forums, people are getting so well trained to think that "new" means better that they really hate older hardware that is just fine for their application
01:48 PM pcw_home: its probably possible to replace the Ethernet chip and fix the board (with a hot air workstation)
01:52 PM bmbbsr: pcw_home, its a Big iron Student Center ther is no Solder at all ,and i got in trouble with my tiny iron on the LED side
01:53 PM bmbbsr: so for me no way to replace a SMD chip
01:53 PM pcw_home: I can try
01:54 PM bmbbsr: Thank you the Student will Like You if you can do it
01:55 PM bmbbsr: Time is nho issue the mashine Build is delayed to 2022
01:56 PM bmbbsr: CaptHindsight, is this you are talking about a arduino based aplication
01:58 PM bmbbsr: pcw_home, can i ask you back in 4weeks on this 7i76e
02:01 PM CaptHindsight: bmbbsr: not specifically, I am asking in general
02:02 PM bmbbsr: CaptHindsight, i'am wondering why not the new Cheep ESP32 with the 2 RT kernals and one nonRT for Communication is used in CNC aplications
02:04 PM CaptHindsight: bmbbsr: because nobody is willing to spend the effort to actually write it and they are only thinking about open loop applications
02:05 PM bmbbsr: Have a Nice Sunny weekend
02:06 PM rmu|w: tomorrow is a public holiday in germany and other catholic parts of europe
02:11 PM CaptHindsight: in the US we get this Monday as a holiday
02:11 PM CaptHindsight: has to do with those wars over there :)
02:13 PM rmu|w: memorial day?
02:13 PM CaptHindsight: yes
02:14 PM CaptHindsight: also considered the start of the summer season
02:15 PM jymmmm: miss0r2: What's your name?
02:16 PM miss0r2: jymmmm: Andreas - Why do you ask?
02:16 PM jymmmm: miss0r2: No, n you were suppose to say miss0r2, it's to see if you rememebred your own name =)
02:17 PM jymmmm: miss0r2: To see how poor your memory is, and if we need to start bankruptcy procedures =)
02:18 PM miss0r2: Indeed :D
02:18 PM miss0r2 is now known as miss0r
02:18 PM miss0r: ahhh... much better
02:18 PM jymmmm: lol
02:18 PM miss0r: Tom_L: I just made a successfull thread
02:19 PM miss0r: Tom_L: Apparently the cad software decided to do an additional 30 degrees of travel after the depth was reached... with no z movement, mind you.
02:19 PM miss0r: Clearing that up fixed it
02:19 PM jymmmm: ve7it: Lawernce!!!!
02:19 PM ve7it: jymmmm, !
02:20 PM jymmmm: ve7it: Are you on Victoria Island?
02:21 PM ve7it: Vancouver Island..... Victoria is about 2hours drive south from here (same island)
02:21 PM ve7it: Island also goes about 4hours drive north from here
02:21 PM jymmmm: ve7it: That is some SERIOUSLY thick undergrowth
02:21 PM ve7it: my bush or the islands?
02:22 PM jymmmm: Hmmm, IDK, just saw a special on Vancuver ISland, where 10 ppl were placed 5 miles about to survive the longest
02:22 PM ve7it: yea... west side of island is pretty much rain forest
02:22 PM jymmmm: apart*
02:23 PM jymmmm: And your side isn't?
02:24 PM ve7it: yea... I go bear hunting where that was filmed.... missed the trip this year due to virus.. it is beautiful, but ya dont want to get lost!
02:24 PM jymmmm: Yeah, one guy tagged out within hours due to the sheer qty of bears, I would too
02:25 PM ve7it: east side is a little more open... farming on a coastal plain ( for maybe a 5 mile wide strip, then mountains )
02:25 PM jymmmm: and you are on the east side?
02:26 PM ve7it: yup... looking across about 20 miles of water to the mainland.... Whistler is about 80 miles inland on the mainland side
02:28 PM jymmmm: gotcha. I was watcing the show and wondering if I could survive there. In some areas I saw 3 to 5" diam trees, and I'm thinking, cut those suckers down and make a bear fence =)
02:32 PM jymmmm: ve7it: do you have battery backup?
02:35 PM ve7it: https://drive.google.com/open?id=1jgpU7QIrG8hmsVKus8IXmL7jrUjRwyTd
02:35 PM jymmmm: ah ok
02:36 PM ve7it: jymmmm, I do have a small ups on computer and router
02:36 PM jymmmm: ve7it: nothing on the ham gear?
02:36 PM ve7it: also 1.8Kw honda gen on propane and a 6kw diesel genset
02:37 PM jymmmm: Nice, which conversation kit did you use on the honda? I have the EU2000i
02:37 PM ve7it: The hame gear is on 2 big gell cells that are float charged.... they are very old now... old telco batteries I think
02:39 PM jymmmm: ve7it: Ok, I have two projects you might be interested in... 1) i building your own iron battery, and 2) I'm working on building a 14.8V@60AH battery
02:39 PM ve7it: I have an old honda noisy contruction type genset... converted it last year to make it more reliable for starting when needed... some chineese carb kit bolted right on
02:40 PM ve7it: fingers not connected to brain....
02:40 PM jymmmm: ve7it: 1) the iron battery... http://oh8stn.org/blog/2018/12/09/diy-solar-generator-576wh/ youtube video showing the build there too
02:40 PM ve7it: tell me more.... saw some of your 14.8v battery discussion... those are cool cells
02:41 PM jymmmm: He's a ham in norway iirc
02:43 PM ve7it: there is a guy building a new house across the street... he put 8kw in solar panels on his roof tied to the grid (no batteries). Its interesting here... the power company doesnt want to pay you for power, but they will authorize connection of a solar installation that keeps your bill at 0.
02:44 PM ve7it: Pretty gray winters here... it will be very interesting to see how his system performs... sales hype vs real power production
02:45 PM jymmmm: ve7it: 2) My battery is based on those 3.7V@60AH cells. I plan on doing 4S, so 14.8V@60AH = 888WH, with a BMS. Then add an inverter, a way to charge from vehicle, mains, and perhaps solar too
02:46 PM jymmmm: ve7it: The battery+bms+connectors should cost me about $160, so roughly $0.13USD per WH
02:47 PM ve7it: prices are getting interesting as surplus ecar batteries come available... just need to bolt a tesla to the roof!
02:48 PM jymmmm: You cna already do that with a prius, they have a module to power your home from it directly, just not in North America
02:48 PM CaptHindsight: anyone know the exact chemistry of the cells that tesla uses?
02:48 PM ve7it: I am watching batteries as I want to build an ebike.... 48V 15AH is in the range of batteries I am looking at.
02:48 PM jymmmm: and it will start the engine automatically when the battery gets low
02:49 PM ve7it: CaptHindsight, as far as I know, the original teslas used like 6000 cells of the 18650 Lipo variety
02:49 PM CaptHindsight: https://electrek.co/2020/04/24/tesla-paten-electrode-million-mile-battery/
02:50 PM CaptHindsight: ve7it: were they buying them or making them?
02:50 PM jymmmm: ve7it: https://diysolarforum.com/threads/bms-common-port-vs-seperate-port.468/ this sight has a lot of info you might be able to use
02:51 PM ve7it: tesla now has huge battery factories
02:51 PM jymmmm: ve7it: MY battery should weight in at about 8 lbs
02:54 PM CaptHindsight: ve7it: I wasn't sure if they made the cells or just assembled the packs
02:59 PM jymmmm: ve7it: the batteries new from china $500 https://www.aliexpress.com/i/33036157794.html
03:01 PM perry_j1987: afternoon guys
03:02 PM jymmmm: ve7it: https://diysolarforum.com/threads/lg-chem-batteries-from-battery-hookup-5-94-kwh.4592/
03:02 PM jymmmm: hi perry_j1987
03:05 PM XXCoder: dazng thats expensive battery
03:06 PM perry_j1987: bought a new truck
03:06 PM perry_j1987: now my toy money is gone for a while
03:16 PM ve7it: jymmmm, that battery place has a lot of choices for surplus batteries... shipping to Canada is rude... $130USD for one order I put together
03:18 PM jymmmm: ve7it: HazMat fees, know anyone in Washington state?
03:19 PM XXCoder: 500 usd per mile if I act as delivery
03:19 PM jymmmm: $100/mile delivery service
03:20 PM jymmmm: CBD
03:20 PM ve7it: not really.... with ferries it is an all day round trip to seatle and about $200 in fares! + gas
03:20 PM XXCoder: did I say it was cost? nay
03:20 PM XXCoder: its my fee ;)
03:21 PM jymmmm: ve7it: That's a business you could start... US delivery to Canada, slow, but much cheaper
03:23 PM jymmmm: ve7it: Just dress like Santa Claus and nobody will ask questions =)
03:23 PM XXCoder: when I had a business I shipped to canada cheaper than people in cananda can ship to canada
03:24 PM ve7it: yup... like internal flights... could fly to London cheaper than to a northern community in this province.
03:28 PM Deejay: gn8
03:30 PM Tom_L: miss0r glad you figured it out
03:32 PM XXCoder: what was issue?
03:33 PM Tom_L: cad software had a mind of it's own
03:35 PM miss0r: I have the first "plug" done. I will upload picture evidence now :)
03:35 PM XXCoder: pics or it didnt happen ;)
03:36 PM Tom_L: that's my policy
03:36 PM miss0r: :]
03:36 PM miss0r: https://imgur.com/a/sxAjcLp
03:36 PM miss0r: Its hard to make out the thread... its hard to take a photo of something that shiny :D
03:37 PM miss0r: its a M65x3.5 thread
03:37 PM XXCoder: looks nice
03:37 PM miss0r: Thanks... I wrecked 3 before I figured out what was going wrong...
03:38 PM Tom_L: looks good
03:38 PM XXCoder: what was happening?
03:38 PM miss0r: For some reason the cad decided that I could not just simply stop doing a helix and move to the center...
03:39 PM miss0r: It insisted that I needed to move aditional 30 degrees without moving down in z, before it would move to center - effectively wrecking 30 degrees of threads
03:39 PM Tom_L: typically those threads will have an undercut at the bottom
03:39 PM miss0r: I could not persuade the cad to not do so, I had to remove it in the Gcode
03:39 PM miss0r: Tom_L: They do here as well
03:39 PM miss0r: (hard to tell on the photo)
03:39 PM Tom_L: yeah
03:40 PM XXCoder: wow weird
03:41 PM miss0r: I still need to drill a vent hole in the top and engrave some breaking fluid information to the lid
03:41 PM miss0r: yeah.. I have no idea what that was about
03:41 PM miss0r: also, I did not see it when I turned the 3D helix drawing.. or I was not looking hard enough that is
03:42 PM miss0r: I can see it now that I know it is going to do it
03:42 PM Tom_L: did you give it a start / stop angle?
03:42 PM miss0r: nope
03:42 PM miss0r: just a start depth and an end depth
03:42 PM miss0r: and ofcourse the diameter and pitch
03:42 PM miss0r: I have defined a starting point, though
03:43 PM miss0r: but nothing that should force it to exit it anywhere in particular
03:43 PM XXCoder: wonder if theres settings on thread finishing
03:43 PM miss0r: indeed.. well, it has no idea it is a thread, as I am just using a helical tool path
03:43 PM XXCoder: aha maybe thats finish pass
03:44 PM miss0r: no finish pass defined
03:44 PM XXCoder: if its a bore, then it would need to finish all around so theres no stub spot
03:45 PM miss0r: that is defined by a check box called "make path at final depth", which is unchecked
03:45 PM SpeedEvil: miss0r: is that a replacement oil cap?
03:45 PM miss0r: SpeedEvil: yeah. I hope I can make it fit the replacement oil resevoir I also have to make :)
03:46 PM SpeedEvil: miss0r: Meanwhile, I approached a similar problem on my tree pruner chainsaw by sanding off the outside plastic threads from the end of the tank, jamming a 2l bottle top + cap over it with PTFE tape, and securing with a couple zip-ties.
03:46 PM SpeedEvil: Works great and is airtight. (minus the hole I drilled for a vent)
03:47 PM miss0r: on this piece of brilliant english engineering, it was decided to place the two resevoirs for clutch and brake bluid right next to the dashboard in full sunlight.. that original plastic does not handle UV well...
03:47 PM SpeedEvil: Oh dear.
03:47 PM miss0r: lol nice
03:47 PM SpeedEvil: Aluminium is somewhat more UV resistant.
03:47 PM miss0r: also.. I have found out that I can buy two plastic replacements for 50usd....
03:48 PM miss0r: BUT I AM COMPLETING THIS
03:48 PM SpeedEvil: :)
03:49 PM miss0r: SpeedEvil: This is the first attempt at making the resevoir: https://imgur.com/a/qp3NoIX
03:49 PM miss0r: I fscked the threads and turned them down, just to see what it would look like
03:50 PM SpeedEvil: That looks robust.
03:50 PM miss0r: well it is.. All the dimensions are copied from somethat that was already robust when it was made from plastic...
03:51 PM miss0r: :)
03:51 PM SpeedEvil: I prefer brass sheet for that sort of thing, as it can just easily be formed and solderd.
03:51 PM SpeedEvil: But for that size of container, not really an issue.
03:53 PM miss0r: nah. Now I just want to make it pretty.. :) Although, I think I might have to beadblast it to make it less shiny. I don't want to have it constantly blinding me while driving in the sun
03:56 PM Tom_L: sounds like you need a vibratumbler
03:56 PM XXCoder: would vaporblasting cause texture too? or too weak? lol
03:56 PM miss0r: I wouldn't mind having that, truthfully
03:57 PM miss0r: XXCoder: It slightly mattens it
03:57 PM XXCoder: theres bunch of materials like glass or walnuts
03:57 PM miss0r: using glass that is
03:59 PM XXCoder: i guess co2 ice is too weak to affect surface which is the point
03:59 PM miss0r: I have no experience with that, but I assume it would be too weak
04:18 PM miss0r: showcase photo, vent is drilled and rubber gasket inserted: https://imgur.com/a/3h02RQa
04:18 PM miss0r: Thats it for tonight. See you around
04:21 PM Tom_L: nice one
04:29 PM perry_j1987: whats that
04:38 PM jymmmm: perry_j1987: IDK, but looks cool =)
04:40 PM Tom_L: oil cap
04:40 PM Tom_L: oil reservoir cap
05:59 PM andypugh: Somebody just sent me a link to a Youtube video of me on the telly in 1987.
05:59 PM skunkworks: heh. the traj section had maximum acc set to 6in/sec². wondered why it seemed sluggish even though i increased the axis acc
06:00 PM skunkworks: andypugh: how?
06:00 PM andypugh: How do you mean how?
06:01 PM skunkworks: so.. 50in/sec² has a peek error now of .0002"
06:01 PM skunkworks: andypugh: how did they get the videi?
06:01 PM andypugh: They found an old VHS of “Top Gear” (a popular motoring programme) that our Fire Engine (and myself, as a 20-year-old) were on.
06:02 PM Tom_L: B&W ?
06:02 PM Tom_L: :)
06:02 PM skunkworks: wow! that is awesome!
06:02 PM andypugh: https://youtu.be/3KiARdTBmVA?t=209
06:03 PM andypugh: actually, rewind to the beginning
06:05 PM Tom_L: pretty cool
06:08 PM skunkworks: andypugh: which one is you?
06:08 PM andypugh: The one closest to the camera at 209 seconds.
06:10 PM skunkworks: got it :)
06:17 PM skunkworks: andypugh: does that still go on?
06:17 PM andypugh: What?
06:18 PM skunkworks: (the run)
06:18 PM andypugh: Yes. But not this year.
06:19 PM skunkworks: ah. I bet
06:20 PM andypugh: 2019: https://www.youtube.com/watch?v=cENlwJT4ggA
07:08 PM veegee: CaptHindsight I bought the forklift. I test drove it and checked for the things you said. It worked great
07:09 PM veegee: Turns out they were only using it indoors and selling it cheap because the economy slowing down and all that
07:09 PM andypugh: That’s one heck of an impulse buy.
07:09 PM veegee: andypugh lol! I was talking about it for the past 2 days on here
07:09 PM veegee: I just set up a hobby metalworking shop with a friend
07:10 PM andypugh: I wish I had the space to even consiser that.
07:10 PM veegee: And I need to load my vertical mill and stuff
07:10 PM Tom_L: quite the hobby ehh?
07:10 PM veegee: I got the Hyster S50CT(?) for $3,500 CAD
07:10 PM veegee: Tom_L yeah I need to figure out how to make some income quick before it eats through my savings
07:11 PM Tom_L: sell masks?
07:11 PM veegee: The thing looks barely used. Dude threw in a full tank of propane
07:11 PM Tom_L: everyone else is
07:11 PM Tom_L: nice
07:11 PM veegee: Tom_L I only have the 3m respirators that protect me, but not other people
07:12 PM veegee: But I have the good P100 filters and organic vapour cartridges with acid gas protection
07:12 PM veegee: People are too stupid to know that for their purposes, it's equivalent to me not wearing a mask so I get away with it
07:12 PM andypugh: (I had to design the fly-press base so I could slot a bicycle underneath. The bandsaw table bolts to the flypress table. The cutter grinder is on top of the lathe tool roller cabinet, that needs to be on rollers so that I can get to the lathe oil change stuff and tension belts etc. The lathe just has room at the other end for gas bottles for the welders. on a shelf under the workbench.)
07:12 PM Tom_L: you should jump into the 'i survived' market
07:13 PM Tom_L: hats, tees, mugs....
07:13 PM andypugh: Mask making machine is $60k. 5k masks per day.
07:14 PM veegee: andypugh are you serious?
07:14 PM veegee: I can buy that right now
07:15 PM veegee: But no idea what the cost of raw materials is and all that
07:15 PM andypugh: https://www.aliexpress.com/item/4000963428437.html
07:16 PM veegee: Shipping costs $70,000 lol
07:16 PM andypugh: Hmm, not the one I saw before. Shipping is crazy
07:16 PM veegee: But I would figure the market is saturated by now
07:17 PM veegee: And have to think about certification and actual filtering capability testing
07:17 PM andypugh: https://www.aliexpress.com/item/4000844441816.html
07:17 PM andypugh: Cheaper shipping
07:18 PM andypugh: My workplace bought one. They give us masks at the door now.
07:18 PM veegee: Why aren't Costco/Walmart etc doing that now
07:19 PM veegee: How do we know what the filtering capability is?
07:19 PM Tom_L: i dare say most of the ones i've seen are for looks
07:19 PM andypugh: If you make them, it depends in the material you xhoose.
07:19 PM andypugh: (And, the single-car-garage I described a few minutes ago, one side) https://photos.google.com/photo/AF1QipNaWjnoycsYIbkmKGxbxXvlZYGE7z0Dd5dJ2dtM
07:20 PM Tom_L: 404
07:20 PM veegee: 404
07:20 PM veegee: I'd do it, but seems like the market would be saturated
07:21 PM andypugh: Hmm. https://photos.app.goo.gl/DRmJsTPbMRNHDq6F6
07:21 PM veegee: Looks like a very risky thing
07:22 PM veegee: andypugh where do you work?
07:22 PM andypugh: Ford
07:23 PM andypugh: They bought a mask machine for the US, UK, EU and China, I believe.
07:23 PM veegee: You mean just one for all of those locations?
07:23 PM veegee: Or one for each location?
07:23 PM veegee: $100,000 for them is like finding a penny between the couch cushions
07:23 PM veegee: like less than that
07:23 PM andypugh: One for each locatio.
07:24 PM veegee: If you had $100,000 right now, would you buy it and make masks?
07:24 PM andypugh: Yeah, I think they can’t do maths. If I die of CoVid it would save them the price of a mask machine.
07:24 PM andypugh: So they could save double the money by not biyng them
07:25 PM veegee: Ok now I'm actually kinda interested
07:25 PM veegee: but I don't want to risk $100k
07:25 PM veegee: But I do have the warehouse space to do it
07:25 PM veegee: Who would I sell to though?
07:25 PM andypugh: They bought the machine 2 months ago, when supply was an issue.
07:25 PM andypugh: What’s the going rate on eBay?
07:26 PM andypugh: or Amazon?
07:26 PM veegee: I searched face mask and got a page full of shitty cloth mask results
07:26 PM andypugh: The trick would be to find a niche colour, or something.
07:26 PM Tom_L: andypugh, when you built lcnc for the rpi did you use ./configure --with realtime=uspace flag?
07:26 PM andypugh: Tom_L: Tes
07:26 PM andypugh: Yes
07:26 PM Tom_L: thanks
07:26 PM veegee: about $50 CAD for 50 masks
07:27 PM Tom_L: will that let it run nomally then?
07:27 PM Tom_L: no run in place...
07:27 PM andypugh: I reckon you need a gimmick at this point, or to have got in earlier.
07:28 PM veegee: Yeah probably
07:28 PM andypugh: Tom_L: You are rip unless you build debs. I am not sure if building debs works in Pi. It didn’t in November.
07:29 PM Tom_L: i'm trying to compile 2.8 for it instead of 2.9 which is on the image
07:44 PM CaptHindsight: veegee: that would be >$5K USD here
07:56 PM veegee: Now time to put some servos on it to make it an R/C forklift
07:57 PM jdh: AGV(FL)
07:57 PM veegee: So I can mount a bucket on the forks and paint/wash the walls up high and roll the forklift along
07:59 PM jdh: we get get a forehead scan coming through the vehicle gate by a guy with a fluke thermometer who also hands us a surgical mask.
08:09 PM jymmmm: jdh: You should put a heating pad on your forehead before getting to the gate, so it reads 115F =)
08:10 PM andypugh: jymmmm: No, you shouldn’t. Just having the idea is as far as this needs to go.
08:10 PM jymmmm: andypugh: At 115F, you would be DEAD
08:11 PM andypugh: Because it would lead to being not allowed in, then contact tracing, and lots of ther folk being tested, and quarantined and, and…
08:12 PM andypugh: Like the security guard knows that?
08:13 PM jdh: we do have armed guards at the gate. the guys doing temp scans are just contractors. the guy I got today is an electrician
08:14 PM jymmmm: jdh: using a fluke temp gun?
08:16 PM jdh: yep.
08:17 PM jdh: I heard it had to read less than 95F
08:17 PM jdh: but, never asked. and I try not to touch the mask he hands you with the gloves he has been wearing to play on his phone and drink coffee
08:19 PM jymmmm: heh
08:20 PM jdh: I just say thank you and drive by
08:21 PM Tom_L: mask not required?
08:26 PM jymmmm: Just lick his face and keep driving
08:29 PM CaptHindsight: I go out in a Santa costume
08:29 PM jdh: He's wearing a mask.
08:30 PM jdh: mask required at work if you can not be distant for x amount of time.
08:56 PM Tom_L: andypugh, do you recall how the debs failed?
08:56 PM Tom_L: seems to be building
08:56 PM andypugh: I didn’t get that far, so it has probably been fixed.
08:58 PM CaptHindsight: is USPS 2 day priority still taking 3-4 days?
08:58 PM Tom_L: no idea
08:58 PM Tom_L: my usual 2 day is looking like it's back to 2 days again though
08:58 PM CaptHindsight: a few weeks ago i noticed when shipping it was telling you 3+ days
09:32 PM skunkworks: pcw_mesa: So - the reason it looked so good is it was capping the acceleration at 6in/s^2...
09:32 PM skunkworks: So - at 50in/sec^2 I get a peak following error of .0002"
09:32 PM skunkworks: (still ok with that)
09:34 PM skunkworks: so that is 10 encoder counts. (which is what I would expect)
09:35 PM skunkworks: now it is pretty instant in moving to 150ipm ;)
09:39 PM skunkworks: (that poor little lathe - I think from the factory it was 30ipm max)
09:39 PM skunkworks: we need to get some automatic oiling on it.
09:40 PM Tom_L: ok debs built
09:40 PM andypugh: Grand
09:41 PM Tom_L: looks like it built es fr en
09:42 PM Tom_L: wonder if i need linuxcnc-uspace-dbgsym_2.8.0-pre1_armf.deb
09:42 PM Tom_L: 6 debs in all
09:44 PM Tom_L: no those 3 are docs
09:49 PM Tom_L: looks good.. installed ok
09:51 PM andypugh: I dont think you need dbgsym]
09:51 PM Tom_L: no, i just loaded the one main .deb
09:51 PM Tom_L: should i post them somewhere?
09:51 PM skunkworks: Grounding the drives and power and a few other things so far seems to have stopped the random estops..
09:52 PM andypugh: There are Pi debs on the buildbot now
09:52 PM Tom_L: for 2.8?
09:52 PM Tom_L: i didn't know that
09:53 PM andypugh: http://buildbot.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-armhf/]
09:54 PM Tom_L: good to know :)
09:55 PM Tom_L: which one to use though?
09:55 PM Tom_L: latest date?
09:55 PM andypugh: I would assume so
09:56 PM Tom_L: well at least i know it builds ok on the arm
10:02 PM jymmmm: Floating table... https://youtu.be/80uQSWkdevQ?t=1141
10:02 PM skunkworks: well neat.. Looks like the external raid box was failing...
10:02 PM skunkworks: Replaced it and so far so good.
11:39 PM jymmmm: skunkworks: you replaced the raid box? Like the whole thing?
