12:00 AM CaptHindsight[m]: use solder
12:08 AM miss0r: But with my own painting skills(Rather lack hereof) I would end up filling it to a massive glob that no air can penetrate :D
12:08 AM miss0r: It has 1mm thick fins, with a 1.3mm spacing
12:08 AM XXCoder: well can always mix solvent into paint till its very light
12:08 AM CaptHindsight[m]: yeah ^^
12:08 AM XXCoder: then dip it in and out. tape over areas that will be contact to heat source
12:08 AM miss0r: *someone* will be able to. But that pool of people does not include me :D
12:08 AM miss0r: my trackrecord with paint, tells me to stay well clear :D
12:08 AM CaptHindsight[m]: https://www.instructables.com/Simple-Tin-Plating-Copper-Without-Energy-or-Danger/
12:08 AM miss0r: indeed. I do have alot of 99.99% nickel strips I could use for plating though
12:08 AM CaptHindsight[m]: or remove the heatsink yearly and soak in acid
12:10 AM miss0r: I used to own this one back in the day: https://www.hwp.ru/Coolers/Volcano.11xe/Thermaltakevolcano11_4.webp
12:11 AM miss0r: better view: https://www.overclockersclub.com/siteimages/articles/thermaltakevolcano11/image4_thumb.jpg
12:11 AM miss0r: that looks all copper to me
12:12 AM XXCoder: wha https://inotrident.plasmics.com/
12:12 AM XXCoder: induction heating plastic how
12:13 AM miss0r: nah. Its just the nozzle that in induction heated. Then the plastic is forced through the heated nozzle like normally
12:13 AM miss0r: is*
12:13 AM XXCoder: ahh makes sense
12:13 AM miss0r: but they sure made it look spaceage :)
12:14 AM miss0r: anyway. I need to get on the road and service clients. See you around
12:14 AM XXCoder: later :)
01:57 AM Deejay: moin

08:25 AM skunkworks: morning
08:43 AM perry_j1987: morning
10:21 AM JT-Shop: I had to put conditional visibility for the slide buttons on the whirlpool machine
10:52 AM perry_j1987: roycroft i setted on the gridfinity design of boxes for my shop
10:52 AM perry_j1987: roycroft seems to have a huge community of people making stuff for the system
10:52 AM perry_j1987: hopefully keep me from having to design my own stuff for as much as possible
11:02 AM JT-Cave: replacement bowl from King Author Baking is also in a million pieces
11:12 AM roycroft: i might have just used the gridfinity design if it existed when i designed mine
11:12 AM roycroft: it's very similar to what i did
11:13 AM roycroft: i know that gridfinity has a bunch of other components besides hardware/fastener storage bins, but i'm not interested in anything else
11:14 AM roycroft: for my drawers that do not hold hardware/fasteners, i'll use my cnc router, whenever that is ready, to make custom inserts for holding tools, etc.
11:16 AM roycroft: i also made the decision, for better or worse, to not have a grid system in the drawers
11:17 AM roycroft: my thinking on that is that if i designed the boxes to fit snugly across the width of the drawer, and had a way to keep them from sliding back when a drawer is not full (and i have that), then it wouldn't be necessary to have the grid
11:17 AM roycroft: especially since the drawers are on ball-bearing drawer slides, and operate smoothly
11:33 AM perry_j1987: i have thought about mdf drawer inserts too of course
11:33 AM perry_j1987: would be neat if we had that colored MDF they have in europe
11:35 AM GTKplusplus6432[: I'm having a very weird problem with g38.2
11:36 AM * GTKplusplus6432[ uploaded an image: (1416KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/AXvmETyFGUJxWkNhCmsIVdOz/rn_image_picker_lib_temp_05dbe666-ba1e-4173-b085-3f669bdaf436.jpg >
11:36 AM GTKplusplus6432[: So, I'm running this probing program. When it gets to g38.2 it performs the move. It moves down. It stops. And then it says, on next line "probe is already tripped on next move
11:37 AM GTKplusplus6432[: Nevermind
11:37 AM GTKplusplus6432[: G38.2 is modal
12:12 PM LukePighetti[m]: no problem at all, my only goal was to get a linuxcnc discord setup, this one is more active, probably best for people to use this one!
01:44 PM CaptHindsight[m]: https://github.com/tomverbeure/panologic these look interesting for LCNC, they are ~$35 used
01:59 PM CaptHindsight[m]: $5 FPGA boards EBAZ4205 https://github.com/xjtuecho/EBAZ4205
02:07 PM JT-Shop: great if you live in mainland china...
02:09 PM CaptHindsight[m]: $25+ shipping on Ali
02:12 PM CaptHindsight[m]: https://alitools.io/en/showcase?search=EBAZ4205
02:23 PM CaptHindsight[m]: https://www.youtube.com/watch?v=b6g5tNZZnVc
03:15 PM roycroft: i might argue that there is nothing great about living there
03:16 PM CaptHindsight[m]: if you like Chinese food it's not bad
03:16 PM roycroft: we get better ingredients here
03:16 PM roycroft: so there can be better chinse food here
03:17 PM CaptHindsight[m]: can you watch your next meal being slaughtered and cleaned out front on the sidewalk?
03:18 PM CaptHindsight[m]: uhmerican restaurants are not very dramatic
03:18 PM roycroft: since most of the food i eat is not slaughtered, i'm not sure that matters much to me
03:19 PM CaptHindsight[m]: do your veggies die natural deaths or were they murdered?
03:20 PM CaptHindsight[m]: https://www.youtube.com/watch?v=vXIdcA6mlV4
03:31 PM perry_j1987: i wonder if i could rig up some sort of o-ring plug that presses in the back of these er16 tool holders to shoot through the collets
03:31 PM perry_j1987: on this gang tooling
04:02 PM JT-Shop: got a photo of the beast?
04:25 PM perry_j1987: me?
04:25 PM perry_j1987: just those straight shaft er16 tool holders with the through hole
04:27 PM CaptHindsight[m]: https://3dprint.com/293842/lost-ice-casting-researches-3d-print-ice-to-build-complex-internal-microchannels/
04:28 PM perry_j1987: hope they have a battery backup on their freezer :P
04:54 PM skunkworks: CaptHindsight[m]: any luck?
04:55 PM CaptHindsight[m]: haven't gotten to it yet
04:57 PM CaptHindsight[m]: ntulinux/memleak will figure it out later
05:14 PM JT-Shop: interesting you have to use a combination of binary to decimal and decimal to hex on the P1AM PLC
05:16 PM JT-Shop: and bit masking to read inputs
05:29 PM CaptHindsight[m]: https://www.binaryhexconverter.com/binary-to-hex-converter skip a step
05:37 PM XXCoder: roycroft: seems today is last 80s day
05:37 PM XXCoder: f
05:38 PM CaptHindsight[m]: skunkworks: I'll be sure to send you the fix
05:38 PM XXCoder: not bad. rest of week at 70s f
05:38 PM CaptHindsight[m]: same here starting Sunday
05:39 PM roguish[m]: my forecast
05:39 PM * roguish[m] uploaded an image: (68KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/ennrwShqDTZyqXaKeoAYyFIV/image.png >
05:39 PM roguish[m]: 97 right now
05:44 PM roycroft: 29 here right now, and then a few days of cooling off before we're back in the 30s
05:45 PM roycroft: but the important thing is that it's getting late in the season, and it is cooling off earlier at night now
05:45 PM roycroft: and getting fairly cool overnight - the low tonight will be 14, and tomorrow night 11
05:45 PM roguish[m]: we were still 72 at midnight last night....
05:45 PM roycroft: it's when it stays in the 20s all night that things stay uncomfortable
05:46 PM JT-Shop: the important thing is I'm making sense of the programming for the P1AM
05:46 PM roguish[m]: thought you
05:46 PM roycroft: i just did some resawing
05:46 PM * JT-Shop feels like Tron
05:46 PM roguish[m]: you're retired.
05:46 PM roycroft: i had some 6/4 ash that was 9" wide
05:46 PM JT-Shop: that's what I thought
05:46 PM roycroft: i needed two boards 7/8" thick
05:46 PM JT-Shop: how did that go?
05:46 PM roycroft: so i resawed it
05:47 PM JT-Shop: roguish[m], for 5 weeks the wife is 3 years older than me :)
05:47 PM roycroft: i have two 7/8" thick boards now
05:47 PM roycroft: (i cut it in half lengthwise first)
05:47 PM roycroft: and with the cutoffs i'll get a full 3/8"
05:47 PM roguish[m]: JT-Shop: then you catch up a bit....
05:47 PM roycroft: so i'm pretty happy
05:48 PM roycroft: the board was 6/4, but it was s2s, so it really started out at 1-7/16" thick, not 1-1/2"
05:48 PM JT-Shop: when you resaw (I have almost no experience) is feed speed the most important thing?
05:48 PM roycroft: everything is the most important thing :)
05:48 PM JT-Shop: I hear that
05:48 PM roycroft: to get good results it all has to be spot on
05:49 PM roycroft: when i raised the blade guide to the height i needed i checked the fence for parallelness (vertically) to the blade
05:49 PM roycroft: and it was off by about 1/64"
05:49 PM roycroft: i spent a fair amount of time fussing with that to get it perfect
05:50 PM roycroft: the bow products bandsaw featherboard is amazing
05:50 PM roycroft: i got that set up to put a fair amount of pressure on the board just in front of the blade
05:51 PM roycroft: the board was jointed so the edge that rides on the table was exactly 90 degrees from the face that rides on the fence
05:51 PM roycroft: and after all that, including setting the blade up well, yes it's all about feed rate
05:52 PM roycroft: and handling of the board
05:52 PM roycroft: that outfeed table i made a few weeks ago is the real key to being able to manage long boards
05:52 PM JT-Shop: I spend a bit of time making sure the blade is parallel to the fence
05:52 PM roycroft: every time you move the blade guide up or down you have to recheck that
05:53 PM roycroft: what i do when i start the cut is hold the board on the infeed side with both hands and guide it very carefully to get the cut started
05:53 PM JT-Shop: I didn't know that
05:53 PM XXCoder: I guess guide arent parallel\
05:53 PM roycroft: after about 6" has gone through, i reach my left hand around behind the blade and "pinch" the board back to the fence
05:54 PM roycroft: on my saw it's a fairly coarse rack and pinion adjuster, with a big knob to lock it in place when the adjustment is done
05:54 PM roycroft: so there's some play in the mechanism
05:55 PM JT-Shop: on the outfeed side of the board you pinch it
05:55 PM JT-Shop: ?
05:55 PM roycroft: and mine is the more precise style - almost all older bandsaws, and many new ones, just have a round or hex rod in a rough-cast socket with a thumb screw to hold it in place
05:55 PM roycroft: yes
05:55 PM roycroft: that helps keep it from wandering off the fence
05:55 PM JT-Shop: https://gnipsel.com/images/p1am/inputs.png
05:55 PM JT-Shop: I've never tried that
05:55 PM roycroft: you don't have to pinch hard
05:55 PM JT-Shop: programming the p1am is colorful
05:56 PM roycroft: you don't need to close up the kerf at all
05:56 PM roycroft: you're just keeping it guided along the fence
05:57 PM JT-Shop: I did pretty good the last few tries with the bow feather rubber thingy
05:57 PM roycroft: i use this to help set the fence parallel to the blade:
05:57 PM roycroft: https://www.axminstertools.com/ujk-technology-bandsaw-buddy-101807
05:57 PM roycroft: you just attach it to the blade with the rare earth magnets
05:58 PM roycroft: there's a groove in front of the magnets for teeth clearance
05:58 PM roycroft: then you just set up your fence parallel to the bandsaw buddy
05:58 PM JT-Shop: I just draw a line on a board and follow the line and if it's parallel to the fence I'm done
05:59 PM roycroft: that works very well
05:59 PM roycroft: the bandsaw buddy avoids having to do a test cut
05:59 PM JT-Shop: I also use a rule to check the blade making sure i don't touch the tooth
05:59 PM roycroft: ash is very hard
06:00 PM JT-Shop: I'd like to look a the web page but it's too demanding
06:00 PM roycroft: and it has that fir-like hard/soft thing going on, which makes it difficult to cut evenly
06:00 PM roycroft: the axminster web page?
06:00 PM JT-Shop: yea, gotta save this save that
06:00 PM XXCoder: website is still viewable with noscript
06:01 PM JT-Shop: did I mention I hate cookies
06:01 PM JT-Shop: what is noscript?
06:01 PM roycroft: welcome to the eu :)
06:01 PM roycroft: even though they're not in the eu any more
06:01 PM XXCoder: jt it stops website scripts from running. firefox and possibly other browsers
06:01 PM roycroft: we're going to have the same type of privacy laws here soon
06:01 PM JT-Shop: really
06:01 PM roycroft: i just reject all the stuff they let me reject, and go on my merry way
06:02 PM roycroft: https://www.ebay.co.uk/itm/UJK-Bandsaw-Buddy-/351732083825
06:02 PM XXCoder: yeah its annoying sometimes but often enough i can just read without stupid ads and such
06:02 PM roycroft: maybe that's better
06:02 PM CaptHindsight[m]: piracy or privacy laws?
06:02 PM roycroft: oh, there's a version for the us now
06:02 PM roycroft: with our funny measurement system
06:03 PM roycroft: it's called the bandsaw companion
06:03 PM roycroft: bandsaw buddy is probably trademarked
06:03 PM roycroft: https://www.chipsfly.com/bandsaw-companion.html
06:03 PM roycroft: there you go
06:03 PM roycroft: you could make one in a couple hours
06:04 PM roycroft: probably in a half hour, actually
06:04 PM JT-Shop: much nicer web page
06:04 PM roycroft: anyway, i find it really useful
06:05 PM roycroft: it just takes a few seconds to set the fence parallel, no matter what blade i have in the saw
06:05 PM XXCoder: how do that bar thing work
06:05 PM JT-Shop: I find a 12" ruler to be as accurate as I need for tracking
06:05 PM roycroft: well, i haven't bothered to do it with my 1/8" blade
06:05 PM roycroft: i don't think it would work well with that
06:06 PM JT-Shop: yep that would be challenge for sure, but if you have a small blade installed your not cutting straight lines anyway
06:06 PM roycroft: if you're resawing something thick and hard, you really want super accuracy
06:06 PM roycroft: right - the only reason i use the 1/8" blade is for cutting curves
06:06 PM roycroft: and now that have that nice new scroll saw (made in your state), i'll rarely use a 1/8" blade on the bandsaw
06:07 PM roycroft: new to me, i should say
06:09 PM roycroft: xxcoder: are you talking about the bandsaw buddy when you say "bar thing"?
06:09 PM * JT-Shop calls it a day
06:10 PM XXCoder: roy yeah. jt night
06:10 PM roycroft: stumpy nubs has a video about it
06:10 PM roycroft: one moment
06:10 PM XXCoder: nubs dont sound like good guy to listen for bandsaw advice ;)
06:13 PM roycroft: https://www.youtube.com/watch?v=h49c-Ckjr9w
06:13 PM roycroft: go in about a minute an 17 seconds and the guy starts demoing the bandsaw companion
06:13 PM XXCoder: ok
06:15 PM XXCoder: magnet fence is interesting
06:15 PM roycroft: i guess his product is called fast
06:15 PM XXCoder: id use indictor bases for much stronger hold but bit expensive
06:16 PM roycroft: yeah, the carter fence might be interesting
06:16 PM roycroft: but can align mine quite easily
06:16 PM XXCoder: i notice hes pressing in like you said to do
06:16 PM roycroft: it really helps
06:17 PM roycroft: every bandsaw blade is going to sit on the tires differently
06:17 PM roycroft: and most bandsaw tires are crowned slightly, so depending on what part of the tire the blade is tracking on, it's going to be angled slightly
06:18 PM roycroft: it's not like a tablesaw where you can align the table and the t-tracks once and be done
06:18 PM roycroft: the alignment is different for every blade on a bandsaw
06:18 PM roycroft: and even the same blade will change its alignment with different blade tension
06:19 PM XXCoder: geez
06:19 PM roycroft: for cutting thing wood, a slight misalignment is not a big deal
06:19 PM roycroft: but when resawing it makes a really big difference
06:20 PM XXCoder: I guess so, because dont want wedged slabs
06:20 PM roycroft: so you just have to go through the steps of aligning everything whenever you install a new blade or adjust the current one
06:20 PM roycroft: right
06:20 PM roycroft: and as i said earlier, even the blade guide can alter the alignment when you move it up and down
06:21 PM XXCoder: I guess its just not designed for repeatability but thankfylly adjustable
06:21 PM roycroft: with a metal cutting band saw you guide the blade by running it hard against the guide bearings
06:21 PM roycroft: but a metal bandsaw blade moves at 150-300fpm or so
06:22 PM roycroft: so it's not going to create a lot of heat
06:22 PM roycroft: with a wood bandsaw you're running at 3000fpm or so
06:22 PM roycroft: if you run guide bearings right up on the blade to hold it rigidly in place you'll be smoking bearings every day
06:23 PM roycroft: so on a wood bandsaw, the "guides" don't touch the blade normally
06:23 PM XXCoder: I saw designs that use oiled wood
06:23 PM roycroft: there's a gap of a few thousandths
06:23 PM roycroft: on my old bandsaw that's what i used
06:23 PM roycroft: i did not oil the wood
06:24 PM roycroft: i replaced the metal guide blocks with lignum vitae blocks
06:24 PM roycroft: lignum vitae is an extremely hard wood, and is naturally very oily
06:24 PM XXCoder: interesting
06:24 PM roycroft: i ran that saw for about 20 years like that
06:25 PM roycroft: i'd go through a couple or three sets of guide blocks per year
06:26 PM roycroft: lignum vitae is expensive, but the guide blocks are about 10mmx10mmx15mm, and a set of them is 4 blocks
06:26 PM roycroft: a small piece of wood makes a *lot* of guide blocks
06:26 PM XXCoder: true. no reason to cheapen when it lasts very long time for one bar
06:26 PM roycroft: actually they're more like 25mm long
06:26 PM roycroft: but still, not much wood
07:33 PM _unreal_: shhhh
07:37 PM infornography: don't speak, just let it happen
07:48 PM t4nk_fn: don't even try, rather ;)
08:46 PM roycroft: xxcoder: i think there's a corrolary to jeremy schmidt's catch phrase when it comes to wood bandsaws: "if there are too many variables to make it practical to make it perfect, make it very adjustable"
08:46 PM roycroft: corollary, rather
08:46 PM XXCoder: nice
08:46 PM XXCoder: and indeed wise sating
08:46 PM XXCoder: saying
08:48 PM roycroft: so i'm not just trying to justify my $800+ investment in the domino machine, but i'm pretty sold on dominos now
08:48 PM roycroft: i just glued up a couple boards that i need to turn into one big, wide board
08:48 PM roycroft: and aligning them was both effortless and worked perfectly with the domino machine
08:49 PM roycroft: i've been using a biscuit joiner for about 40 years, and even after all that time i still have occasional alignment issues
08:49 PM XXCoder: this machine? ;) https://youtu.be/Rt_qRJrerEs
08:50 PM roycroft: the strength of dominos vs. biscuits does not even come into play here, because the glue joint itself should be stronger than the dominos/biscuits, if it's done properly
08:50 PM roycroft: not that one :)
08:50 PM XXCoder: :)
08:51 PM roycroft: https://www.youtube.com/watch?v=sD2QxrwuvJk
08:51 PM roycroft: that one
08:52 PM XXCoder: thats cool
08:52 PM roycroft: it's both more precise than a biscuit joiner and requires no measuring/marking out
08:53 PM roycroft: so it's really fast
09:04 PM XXCoder: nice

09:07 PM XXCoder: sigh someone on matrix gonna ban that guy lol
09:10 PM roycroft: intercourse yourself, spammer
09:10 PM roycroft: :)
09:10 PM XXCoder: lol
09:11 PM XXCoder: its like meat seller trying to sell meat to vegans

09:11 PM XXCoder: this place is way wrong
10:53 PM roycroft: you know, the cast of tos complained a lot about their costumes, and how they did not get laundered regularly and made them all smell rather "ripe" while on set
10:54 PM XXCoder: you sure its not TNG?
10:54 PM roycroft: but the way kirk seems to get his shirt torn or cut or ripped off every episode, that probably wasn't a problem for shatner
10:54 PM XXCoder: first 2 seasons was ... rank
10:55 PM XXCoder: the suits was very stinky lol
10:55 PM roycroft: it was probably a problem on all the series
10:55 PM XXCoder: only first 2 I think
10:55 PM XXCoder: I wonder if sharter tore shirts all time to get of smell lol
10:56 PM XXCoder: rather than looking badass
10:56 PM XXCoder: most ergerous shirt rip is tha vaccine one
10:56 PM roycroft: tonight is amok time
10:56 PM XXCoder: doc shot everyone though shirt, except for kirt. rip sleeves and shot
10:56 PM roycroft: spock gets horny and kills kirk
10:58 PM XXCoder: fun one
10:58 PM XXCoder: first time Vulcan home world was shown, though not a lot of it
10:59 PM XXCoder: if I remember right, it was supposely "close to earth" as in mars, so its all reddish but they changed mind and set planet far from earth
11:01 PM roycroft: i think you're right
11:04 PM XXCoder: did you ever read very early cartoons of star trek?
11:04 PM roycroft: no
11:04 PM XXCoder: early ones has fire coming out of warp engines lol (or in least fire-like flares anyway)
11:04 PM roycroft: i was a weird nerd kid - i wasn't into comics
11:05 PM XXCoder: I never could afford comics lol I read em way later, by downloading
11:05 PM XXCoder: or rather get comics cdrom star trek
11:07 PM XXCoder: example https://www.amazon.com/Star-Trek-Complete-Comic-Collection/dp/B001B5KYR2
11:08 PM XXCoder: earliest ones also get scale weird, ship is quite a bit smaller lol
11:08 PM roycroft: there were fewer pixels in the olden days
11:09 PM roycroft: so folks had to conserve them
11:09 PM XXCoder: lol
11:28 PM W1N9Zr1 is now known as W1N9Zr0
11:55 PM XXCoder: weird that rss-master entered. its a bot that never says anything but new entries in rss feed in rss feed channel in discord
