01:10 AM Deejay: moin
04:08 AM Loetmichel: hehe, just noticed that those CNC6040 are REALLY not meant to do heavy cutting. doing 0.3mm deep cuts in Alu right now, but on one side i forgot to cut away stuff earlier... so the 6mm two flute dips in a whole 2.3mm... result: the whole Z axis tilts enough on the x rails that it cuts 0.3mm deeper than intended. :(
04:09 AM Loetmichel: (not to mention that it sounds REALLY bad)
04:13 AM xxcoder[m]: ouch
04:14 AM xxcoder[m]: hopefully that didnt deform the machine frame
04:18 AM Loetmichel: xxcoder[m]: a 6040 has only two 25mm diameter "free flying" rails on C
04:18 AM Loetmichel: X
04:19 AM Loetmichel: so they simply "spring" a bit when the load increases
04:19 AM Loetmichel: there is nothing bent.
04:20 AM xxcoder[m]: good thing
04:26 AM Tom_L: morning
04:29 AM jpa-: http://essentialscrap.com/cnc/spindle.webm pretty similar to CNC3020 flex
04:32 AM xxcoder[m]: usually because it uses adopor between spindle and collet
04:32 AM xxcoder[m]: it uses set screw so its not centered
04:32 AM xxcoder[m]: or rather co-axial
04:34 AM jpa-: yeah, runout due to crappy spindle, flex due to crappy frame
04:36 AM xxcoder[m]: former is partially fixable
04:36 AM xxcoder[m]: using shims to get it more centered
04:36 AM xxcoder[m]: good for tool life
04:40 AM Loetmichel: jpa-: yes. just more extreme and its not the spindle flexing, its the gantry
04:41 AM jpa-: gantry is the main flex for me too
04:41 AM Loetmichel: the 800W/1500W three phase watercooled spindles are actually not THAT bad unless you get one where the cone for the ER11 is ground off center
04:41 AM jpa-: i'm planning to replace the whole spindle, that 400W DC motor spindle is total crap compared to the 800W three phase vevor spindle I got for a bigger machine
04:41 AM Loetmichel: indeed it is
04:42 AM Loetmichel: not only is it mounted on the motor shaft with a grub screw said motor shaft is 1/4"... WAY to small to take any side loads
04:43 AM Tom_L: one step above a dremel
04:44 AM Loetmichel: still: 2mm deep into alu with a 6mm mill bit is about the end of torque even for the 800W three phase. It drops the RPM enough that the VFD is starting to blink with a warning about slip
04:45 AM Loetmichel: at least at 120mm/sec feed
04:45 AM Loetmichel: 1200mm/min, sorry
04:50 AM jpa-: fswizard says 0.16 kW for that cut, but i guess it depends a lot on the toolbit and friction also
04:50 AM Loetmichel: yep
04:51 AM Loetmichel: standard 2 flute tungsten carbide bit ground for alu
04:51 AM jpa-: my toolbits tend to always gum up with aluminum chips, i should get some better polished ones
04:51 AM Loetmichel: the fact that the gantry flexes may be bad though, getting the cut deeper and so on
04:52 AM Loetmichel: jpa-: and/or get a spray pump bottle and some pure Isopropyl alcohol for cooling
04:52 AM Loetmichel: works great in alu
04:52 AM jpa-: that, too
04:52 AM Loetmichel: drawback: better not having any ignition source around.
04:52 AM jpa-: i have parts coming for mist coolant system, though i'm not sure what fluid i'll run in it
04:54 AM jpa-: it's a shared system at a hackerspace and people do aluminum and steel and whatever, so some general purpose cutting fluid
04:54 AM Loetmichel: btw: shopvacs that draw their cooling air from the vacuum hose and not from the room make decent flamethrowers when you use them to suck up spilled 99,5% IPA. Dont ask how i know :D
04:54 AM jpa-: and i'll have a mode that just blows air for clearing off plastic & wood chips
04:55 AM xxcoder[m]: wd-40 works for alum cutting too
04:55 AM xxcoder[m]: used it few times
04:55 AM Loetmichel: xxcoder[m]: it does. but its expensive AND leave stains on the alu
04:55 AM Loetmichel: IPA doesent
04:56 AM JT-Cave: morning
04:56 AM Loetmichel: mornin' JT
04:57 AM xxcoder[m]: loet its bit cheaper when its in gallons with no pressure
04:57 AM xxcoder[m]: no metal cans too. just plastic
04:57 AM Loetmichel: yeah, still a lot more expensive than pure alcohol.
04:57 AM Loetmichel: at least here in germany
04:58 AM xxcoder[m]: ipa prices rose a lot but probably reverting now
04:58 AM Loetmichel: yep
04:59 AM Loetmichel: what i loke about pure alcohol either ethanol or IPA for cooling is that it tends to evaporate without any residue
04:59 AM Loetmichel: VERY convenient for making parts that are visible afterwawrds
05:01 AM jpa-: somehow having the whole CNC enclosure full of IPA fumes is a bit worrying :)
05:03 AM Loetmichel: jpa-: bah, whats the worst that can happen? a slight "Woof" and you need a new enclosure window. BTDT... :)
05:04 AM jpa-: :D
05:07 AM xxcoder[m]: just start drawing in eyebrows too
05:07 AM Loetmichel: You know, the kind of "woof" from the joke about "how to get a cat to bark? Use a jerrycan of petrol and a lit match on it!" makes.
05:08 AM Loetmichel: xxcoder[m]: funny enough my eyebrows seem to be non-flammable.
05:08 AM xxcoder[m]: ouch
05:08 AM Loetmichel: so far i have been in many of those "woof" moments and never had anything but my arm/hand hairs burned off
05:08 AM xxcoder[m]: lol

09:49 AM roguish[m]: JT-Cave: so, Starlinking????
09:50 AM roguish[m]: very cool
09:57 AM JT-Cave: the box arrives today
09:57 AM JT-Cave: I have the Best Effort plan until they have enough sats to upgrade me to Residential
10:01 AM roguish[m]: what rates are you expecting?
10:01 AM roguish[m]: better than your current?
10:06 AM JT-Cave: I hope so
10:07 AM JT-Cave: <JT-Cave> 13.9 Mbps download 0.61 Mbps upload today
10:07 AM JT-Cave: even if it's only a tiny bit better unlimited is worth changing now
10:10 AM roguish[m]: sounds pretty good. too bad the gov't can't get it's ass in gear and actually do what it talks about.......
10:18 AM JT-Cave: I'm still waiting for my high speed fiber for rural areas to do something besides sit in the ground and not be connected to anything
10:19 AM * JT-Cave heads out for a while
12:44 PM solarwind: CaptHindsight[m] I bought this and it arrived today: https://www.amazon.ca/gp/product/B088BNS8HT/
12:45 PM solarwind: The reviews are probably all correct regarding its thermal shock resistance and so on, but the tolerances are still impressive and the price isn't outrageous
12:45 PM solarwind: I have no plans to subject it to high temperatures. I just want to use it with oils for my machine tools and air tools. All regular plastic syringes degrade, especially the rubber plunger
12:47 PM solarwind: I need to make some out of steel and nitrile O-ring plungers if I can't get the tolerances I need. But I think I can. I was able to turn a 15cm shaft out of mild steel to +/- 1µm on my lathe the other day by finishing with a vertical shear tool
12:47 PM solarwind: Still haven't had a chance to pick up that toolpost grinder from ZincBoy[CAON][m] D:
12:48 PM solarwind: but yeah CaptHindsight[m] that syringe behaves like an air bearing after wearing it in for a few minutes
12:50 PM * roycroft wonders whether a high precision syringe is necessary when used a machinery oiler
12:51 PM roycroft: i was given a box of insulin syringes a few year ago
12:51 PM roycroft: they are old, and glass
12:51 PM roycroft: i find them useful for injecting oil or glue in things, and i have so many that i usually dispose of them after use
12:52 PM solarwind: It's not about the precision, it's just that all the oils except silicone oil eat the plastic and rubber plunger and contaminate the oil
12:52 PM roycroft: but i find a spring bottom oil can works fine for most things
12:54 PM roycroft: for really fine things like watch jewels, a dip oiler is the thing to use
01:17 PM roguish[m]: anyone need a new car. get this one.... https://interestingengineering.com/transportation/electric-hypercar-debuts-us
01:19 PM Tom_L: i'd rather have a gas guzzling bugatti veyron
01:19 PM roycroft: no, i would never want that
01:19 PM roycroft: as an american, i would feel "emascualted" if i drove a thing like that
01:20 PM roycroft: or so i've been told
01:20 PM Tom_L: you could plug it in right next to your prius
01:20 PM roycroft: i'm not sure that's true, but i would not want to risk jeopardising my manhood
01:20 PM roguish[m]: oh come on you guys. ya know ya'd love to drive it....
01:21 PM Tom_L: not if it doesn't make alot of noise
01:21 PM roycroft: i'd be terrified to drive it, actually
01:21 PM roycroft: i'm a good driver, but that's a $3 million car
01:22 PM roycroft: on a closed track with no other vehicles around, it would be fun to drive
01:22 PM roguish[m]: no guts, no glory
01:22 PM Tom_L: the motors might be good for something... cnc
01:22 PM roycroft: but on a highway full of american drivers, i woul dbe absolutely terrified to drive it
01:22 PM roguish[m]: put your two tones to the floor boards......
01:22 PM roycroft: i'm not into sports cars and fast driving anyway
01:23 PM roycroft: i'm more of a putt-putt enjoy the scenery kind of driver
01:23 PM roycroft: keep in mind that i've driven air-cooled volkswagens for much of my life
01:23 PM Tom_L: i had a 68 bug
01:24 PM Tom_L: put a southwind heater in it
01:24 PM roycroft: hopefully not one with that auto-shifting transmission thing
01:24 PM Tom_L: those were kinda hard to find
01:25 PM roycroft: those old bugs had two major problems:
01:25 PM roycroft: 1. the fuel tank was above the carburetor, people did not perform maintainance on the vehicle, the fuel lines would crack, spilling fuel on the engine and causing a big fire
01:26 PM Tom_L: 914 porche were horrid about that
01:26 PM roycroft: 2. the back seat, which sits right on top of the battery, would sag over time, the battery would short out on the seat springs, catching the horeshair stuffing on fire
01:26 PM roycroft: the recurring theme is "big fire that destroys the vehicle"
01:27 PM roycroft: easily preventable, but so often it happened
02:40 PM JT-Shop: just sold my Huth HB-10 :)
02:44 PM xxcoder[m]: jt it arrived? does it work well?
02:45 PM JT-Shop: it == Starlink dish? no, it's out for delivery
02:48 PM xxcoder[m]: oh lol ok
02:48 PM xxcoder[m]: hope it goes well
02:52 PM roycroft: i have a harbor freight tubing roller
02:52 PM roycroft: a little lower tech than that hb-10
02:54 PM JT-Shop: I have a homemade bender for square tube up to 1"
02:54 PM roycroft: nice
02:54 PM roycroft: that would be useful
02:55 PM roycroft: i have a welding table that i can tack weld pegs to, and a rosebud tip for my torch
02:55 PM roycroft: so i can do bends like that too
02:55 PM JT-Shop: https://www.leevalley.com/en-us/shop/tools/power-tool-accessories/guides/68347-festool-guide-rails
02:55 PM roycroft: but not as easily
02:56 PM JT-Shop: looking at the FS 1400/2
02:56 PM roycroft: there are a couple things you should consider before ordering guide rails
02:56 PM roycroft: 1. do you think you might ever build euro-style cabinets using the 32mm grid system?
02:56 PM JT-Shop: no
02:56 PM roycroft: if so, festool have a 32mm grid kit for their routers that works with some of their guide rails
02:57 PM roycroft: those rails have holes drilled in them
02:57 PM roycroft: 2. do you think you'll ever want to use the track saw on a vertical surface?
02:57 PM JT-Shop: hmm, I don't think so...
02:57 PM roycroft: if so, some of the new style rails have a cutout in them that lets you attach some holders that will stick it to a wall
02:58 PM roycroft: so the ones at lee valley are the old style
02:58 PM roycroft: the fs 1400/2 is $145
02:58 PM roycroft: the fs 1400/2 (lr32) is $149
02:59 PM roycroft: so to get the 32mm holes is $4 more
02:59 PM roycroft: 32mm-spaced holes, rather
02:59 PM roycroft: the fs 1400/2-KP, which takes the adhesive pads, is $165
03:00 PM roycroft: https://www.festoolusa.com/products/guide-systems/guide-rails/577043---fs-14002-kp#Overview
03:00 PM JT-Shop: odd the fs 2424/2-lr32 is only 95" long
03:01 PM roycroft: 95.43"
03:01 PM roycroft: because 2424mm = ~95.43"
03:01 PM JT-Shop: seems odd to not be 8' capable
03:01 PM roycroft: there's a 2700 and a 3000
03:02 PM JT-Shop: not in the lr32 series
03:02 PM roycroft: when you're drilling on a 32mm grid you're not normally drilling the full length, top to bottom
03:02 PM roycroft: no
03:02 PM JT-Shop: that makes sense
03:02 PM roycroft: but even if you're making a ceiling-height cabinet with 32mm holes for shelves, you're going to have a little dead space at the top and bottom
03:02 PM roycroft: you're not going to put a shelf pin 32mm above the bottom
03:03 PM roycroft: or even 32mm above the bottom of the bottom panel, which would be 51mm commonly
03:04 PM roycroft: anyway, even though you answered "no" to both questions, the cost difference is so little you might consider one of the other options anyway
03:04 PM roycroft: a nice thing about the ones that take the adhesive pads is that there is a slot for a pad in the middle that is just big enough to fit the systainer handle through
03:04 PM roycroft: so you could carry the saw and the rail with one hand
03:05 PM roycroft: those rails only go up to 1900mm though
03:06 PM roycroft: i think if i were starting fresh today, i'd get a 1400mm kp rail first
03:06 PM roycroft: then i'd get a 1400 lr32 rail
03:06 PM roycroft: and i would be able to join them for ripping 8' sheets
03:07 PM JT-Shop: the only difference is the holes?
03:07 PM roycroft: eventually i'd get a 2700 or a 3000
03:07 PM roycroft: yes
03:07 PM roycroft: i got the 2700, and it works on a 97" sheet of mdf, but just barely
03:07 PM roycroft: there's a big price bump between the 2700 and the 3000, which is why i got the 2700
03:07 PM roycroft: but if i were doing it over i might bite the bullet and get the 3000
03:08 PM roycroft: the 2700 is $355, and the 3000 is $245
03:08 PM roycroft: er,$425
03:08 PM roycroft: i have a 32mm jig system, and it works, but it's fiddly
03:09 PM roycroft: i would never be able to use it in production
03:09 PM JT-Shop: thanks for the info, gotta cut a couple of rafters and install them
03:09 PM roycroft: sure
03:10 PM roycroft: and btw, if you ever end up getting a festool contractor saw, it works on the same rails you'll get for your current saw
03:10 PM roycroft: but you can get special rails that lock the saw on the track and let you set repeatable angles
03:10 PM CaptHindsight[m]: 32mm dia shelf pins,man that should hold some weight
03:10 PM roycroft: your saw won't fit on those rails
03:11 PM roycroft: https://www.leevalley.com/en-us/shop/tools/jigs-guides-and-fixtures/42200-veritas-32-cabinetmaking-system?item=05J0602
03:11 PM roycroft: that is what i have for 32mm grids
03:11 PM CaptHindsight[m]: oh never mind,that must be 32mm spacing
03:11 PM roycroft: it takes a long time to set it up
03:11 PM roycroft: but it is very accurate when set up carefully
03:12 PM roycroft: https://roycroft.us/New_Cabinets/04_Cabinet_Side_Panel.jpeg
03:12 PM roycroft: that was done using the jig
03:12 PM CaptHindsight[m]: looks like a jig with holes spaced every 32mm
03:12 PM roycroft: yes
03:13 PM roycroft: standard drawer slides have their mounting holes on a 32mm grid
03:14 PM CaptHindsight[m]: do they make a jig that actually slides with an encoder wheel?
03:14 PM roycroft: that veritas jig also works as a dowel jig
03:14 PM CaptHindsight[m]: then spacing can be whatever you wish
03:14 PM CaptHindsight[m]: like cnc accuracy without cnc, just the encoder readout
03:14 PM roycroft: i don't think so
03:15 PM roycroft: but you can use a shaper origin for that
03:15 PM roycroft: the 32mm grid has been a standard since the 1950s, though
03:15 PM CaptHindsight[m]: but I don't like stickers
03:15 PM roycroft: it wouldn't be prudent to build cabinets on another grid system
03:15 PM roycroft: you don't need the tape any more
03:15 PM CaptHindsight[m]: say i want to drill decorative holes
03:16 PM roycroft: for small items at least
03:16 PM roycroft: if they're decorative then then they don't need to be precise :)
03:16 PM CaptHindsight[m]: spaced every 35mm
03:16 PM roycroft: in fact, making them precise destroys the "artisan aesthetic"
03:16 PM roycroft: anyway, the shaper origin can do that
03:16 PM CaptHindsight[m]: nah I want to vary the distance between holes like screen print
03:17 PM CaptHindsight[m]: but on big pieces
03:17 PM CaptHindsight[m]: say 4x8 sheets, beyond what the shaper origin can do
03:17 PM roycroft: https://www.shapertools.com/en-us/plate
03:17 PM roycroft: and that work for small stuff
03:17 PM roycroft: i'm sure they'll come out with something for big pieces
03:18 PM roycroft: or you can make something yourself using their tape, but making it more permanent
03:18 PM CaptHindsight[m]: maybe i should first
03:18 PM CaptHindsight[m]: why can't I?
03:18 PM CaptHindsight[m]: no tapes
03:18 PM CaptHindsight[m]: well more like a tape measure
03:19 PM CaptHindsight[m]: encoder reel
03:19 PM CaptHindsight[m]: like a fishing rod and reel
03:20 PM CaptHindsight[m]: https://media.ifm.com/CIP/mediadelivery/rendition/8f9244e89e435a4881577edd5ceeb9dc/-B600-FJPG/RMS001
03:22 PM CaptHindsight[m]: https://www.maslowcnc.com/ like this only more precise
03:23 PM CaptHindsight[m]: encoder cable assisted shaper
03:23 PM roycroft: the maslow router has underwhelmed me
03:23 PM xxcoder[m]: interesting
03:24 PM CaptHindsight[m]: the maslow almost does it right
03:24 PM CaptHindsight[m]: it just needs to be combined with the shaper
03:24 PM Rab: The term of art in my field is "string pot", and the encoding equivalent seems to be a string or "draw wire" encoder.
03:24 PM xxcoder[m]: i think that router is cool, but yeah it has quite number of limitions
03:24 PM CaptHindsight[m]: and it can still be driven by an operator by hand
03:25 PM CaptHindsight[m]: so it would have the range of the maslow but the accuracy of the origin
03:25 PM roycroft: i think that if you wanted to drill a bunch of holes spaced at precisely 35mm you could make a jig to do that in a few minutes
03:25 PM roycroft: festool have purchased shaper
03:26 PM roycroft: and they've done it kind of like cisco do things
03:26 PM roycroft: they bought it for the technology, not the product
03:26 PM CaptHindsight[m]: but I want the flexibility of CNC without the big cartesian system
03:26 PM roycroft: there is already a festool patent for a circular saw that self-adjusts
03:26 PM roycroft: using the shaper technology
03:26 PM CaptHindsight[m]: and I still have two hands
03:26 PM roycroft: so it's a track saw that doesn't need a track
03:28 PM CaptHindsight[m]: maybe a laser guided system is better
03:28 PM CaptHindsight[m]: I can do both and compete with myself
03:29 PM roycroft: https://machineatlas.com/news/new-festool-patent-track-saw-meets-shaper-origin/
03:29 PM CaptHindsight[m]: why we need patent reform
03:29 PM CaptHindsight[m]: fricken obvious again
03:29 PM roycroft: yet there is no prior art
03:29 PM roycroft: they don't have it perfected yet anyway
03:30 PM CaptHindsight[m]: never send a kid to do a mans (adults) job
03:31 PM CaptHindsight[m]: there's the almost do spirit
03:31 PM justHaunted is now known as _justHaunted
03:31 PM _justHaunted is now known as justHaunted
03:34 PM roycroft: i just picked up a nice wristwatch on ebay
03:34 PM roycroft: my current watch needs a service, and the timeframe for that is measured in months, not weeks or days
03:34 PM roycroft: so i thought it would be good to get a second watch that i can wear while the first one is in the shop
03:35 PM roycroft: i toyed with the idea of servicing it myself, but to do it properly would cost me about $1k in tools/equipment
03:36 PM JT-Shop2: cradek, is The Time Guy
03:36 PM roycroft: https://www.ebay.com/itm/175432402700
03:36 PM roycroft: that should look nice with a new crystal
03:37 PM roycroft: andypugh has a horology background as well
03:37 PM xxcoder[m]: many many things is olvious in hindsight
03:37 PM roycroft: or since he's british, i should say an horlogy background
03:37 PM CaptHindsight[m]: he's an adult, what he does in private is not my concern
03:38 PM JT-Shop2: https://timeguy.com/cradek/
03:38 PM roycroft: "Please note: I have temporarily stopped taking new work because my backlog has grown unreasonably long."
03:39 PM roycroft: he's just the same as all the other shops
03:39 PM roycroft: the problem is that watchmakers are dying off in droves, becuase they're mostly ancient
03:39 PM CaptHindsight[m]: didn't cradek mention that he lost his old shop?
03:40 PM roycroft: and not enough young people are taking up the trade
03:40 PM xxcoder[m]: sucks but then we cant mandate people take up hobbies. 😦
03:40 PM roycroft: what i don't get is why you have to leave your watch for months to get a service
03:40 PM -!- #linuxcnc mode set to +v by ChanServ
03:40 PM CaptHindsight[m]: roycroft: well it's mostly just swap batteries and adjust the bands now
03:40 PM roycroft: why not make a reservation, pay a fee up front, and when it's your time you drop it off?
03:41 PM roycroft: those people are plentiful, capthindsight
03:41 PM CaptHindsight[m]: xxcoder: if you have time for hobbies we aren't working you hard enough
03:41 PM roycroft: and they also do case cleanings and replace crystals
03:41 PM roycroft: that watch i just bought needs a crystal, and i'm confident i can get that done quickly
03:41 PM roycroft: it likely needs a service too
03:42 PM xxcoder[m]: capt makes sense. many people with families work 2 jobs, if its not highly paid position job
03:42 PM roycroft: if it does, i'll determine whether that one or my other one is in worse shape
03:42 PM roycroft: and get the service on the one that needs it the most first
03:42 PM CaptHindsight[m]: I only fully destroy my watches, I never just go part way, why i only wear cheap watches
03:44 PM xxcoder[m]: I just use pebble classic
03:47 PM roycroft: i stopped wearing watches a long time ago because i kept destroying them
03:47 PM roycroft: but i do like wearing one at times, and finally figured out that i could wear a watch and keep it nice as long as i took it off whenever i was doing something that might damage it
03:48 PM roycroft: that strategy has worked out well
03:49 PM CaptHindsight[m]: probably less unsuspected street violence there
03:51 PM CaptHindsight[m]: I don't think that the shaper origin even adjusts its Z
03:52 PM CaptHindsight[m]: can you drill a series of holes x distance apart with the shaper origin?
03:52 PM CaptHindsight[m]: and with varying or even the same depths?
03:54 PM roycroft: i'm not sure how it handles z
03:54 PM roycroft: it certainly cannot do 3d carving
03:55 PM roycroft: i'm still not convinced that the shaper origin would be useful for me
03:55 PM CaptHindsight[m]: it doesn't i asked
03:55 PM xxcoder[m]: that wall thing rpouter?
03:55 PM roycroft: when i was starting to work on my 3d router design i considered the shaper origin instead
03:55 PM roycroft: no, the "hand held" cnc router
03:55 PM CaptHindsight[m]: xxcoder: Shaper Origin
03:55 PM xxcoder[m]: if I recall right, it has 2 positions only for z? been a while since I researched that
03:55 PM roycroft: the sticker tape is what made me not be interested
03:55 PM xxcoder[m]: ie no cut an full depth
03:55 PM xxcoder[m]: ah that one dunno
03:56 PM roycroft: it seemed i'd be spending half my money on rolls of tape if i bought one
03:56 PM xxcoder[m]: yeah if I recall right that tape is quite expensive.
03:56 PM CaptHindsight[m]: it needs a way of knowing where Z is and also a way of holding Z position
03:56 PM xxcoder[m]: well if it has 2 position thing also, thats not too bad also
03:56 PM xxcoder[m]: just limited
03:57 PM CaptHindsight[m]: one way to add Z stability is increase the diameter of the base of the shaper
03:58 PM xxcoder[m]: cant do massive voids yeah.
03:58 PM CaptHindsight[m]: so a 2 ft dia baseplate would give you 1 ft dia of Z area
03:59 PM CaptHindsight[m]: if you had an arm to track Z then it could be larger
04:01 PM CaptHindsight[m]: if i commercial the shaper I'd like to use roycroft for the infomercial
04:03 PM roycroft: that's why i like their "workstation" thing
04:03 PM roycroft: for small parts it eliminates the tape
04:07 PM roycroft: building my over/under cnc router/router table is a better solution for me though
04:08 PM roycroft: there are applications for which the shaper origin is perfect, and unmatched, though
04:08 PM roycroft: for example, installing inlay in a wooden floor
04:16 PM xxcoder[m]: indeed
04:16 PM xxcoder[m]: that would be fun for children room. wood floorm then make inlays of random stuff
04:45 PM CaptHindsight[m]: what if want to do 4x8 sheets?
04:46 PM CaptHindsight[m]: 1mm accuracy is more than good enough
04:47 PM CaptHindsight[m]: 1/25th inch
04:55 PM jdh: I have a project to measure items between 60-160 inches long within a few thousandths. and one end of some of the items has an inferred datum.
04:58 PM roycroft: i hope you have really good temperature control in your metrology lab
05:01 PM jdh: yeah. measurement occurs on the factory floor (table)
05:03 PM ZincBoy[CAON][m]: Laser interferometer
05:10 PM jdh: you would have to fixture a target I think.
05:10 PM jdh: the other end has a nice square datum which helps.
05:48 PM xxcoder[m]: just table or Surface?

10:18 PM * roycroft is still dubious about a yo-yo router
10:19 PM * roycroft is willing to be proven wrong
10:19 PM xxcoder[m]: BAH I like irc to discord /me command format a lot better than discord /me format
10:20 PM xxcoder[m]: I do want to try that 4x8 stand up router thing, but no room lol
11:14 PM CaptHindsight[m]: https://www.livescience.com/51026-what-is-trigonometry.html
11:14 PM CaptHindsight[m]: it's all in there
11:16 PM CaptHindsight[m]: adjacent, opposite and hippopotenuse
11:18 PM roycroft: there's a new clickspring clips
11:18 PM roycroft: a longish clip
11:19 PM roycroft: looks like more knurling
11:19 PM xxcoder[m]: aww I wont be able to watch any till I repair pc at sat lol
11:20 PM xxcoder[m]: sat, just in time for certain blondhack video lol
11:22 PM roycroft: he's making a nice knurled brass knob, and he made a hardened form tool for the knob profile
11:24 PM xxcoder[m]: nice. cant wait to watch it. rpi4 stalls too much on videos so ill watch later
11:24 PM roycroft: i cannot wait until november 9th
11:25 PM roycroft: the shouty political ads will stop and the shouty phone calls will stop
11:25 PM roycroft: or at least taper off
11:26 PM Thorhian[m]: Have you tried watching them via MPV instead of in a web browser?
11:27 PM xxcoder[m]: mpv?
11:28 PM Thorhian[m]: It’s a video player. There are scripts out there to stream and play YouTube videos directly to it. Might be more performant.
11:29 PM xxcoder[m]: probably, though in mnost case I watch videos from links in my rss feed program newsflash
11:29 PM xxcoder[m]: so I dont really have links at this time
11:31 PM Thorhian[m]: Ah. I sometimes use a dmenu script to search and play videos.
11:32 PM xxcoder[m]: ok
11:32 PM xxcoder[m]: well if zI browse randomly, most videos just dont interest me
