03:04 AM jym: morning Deejay
03:04 AM Deejay: :)
05:02 AM Tom_L: morning
05:02 AM jthornton: morning
05:02 AM XXCoder: hey
05:03 AM XXCoder: my laser board arrived!
05:03 AM jthornton: yippie
05:03 AM XXCoder: yep
06:08 AM jthornton: plug it in yet?
06:10 AM XXCoder: nah too tired to setup all
09:01 AM gregcnc: wtf?! I dreamed I had a 3d printer
09:03 AM sensille: that doesn't mean anything
09:03 AM sensille: did you wake up suddenly and sweaty?
09:05 AM gregcnc: loud neighbors woke me in the middle of the night
09:06 AM sensille: 3d printers are only good for printing 3d printers. you don't need one, you can just mill one
09:07 AM methods_: wtf you saying 3d printers are great for making vases
09:07 AM methods_: they wont' hold water
09:07 AM gregcnc: a 3d printer would make more than my mill right now
09:07 AM methods_: but it seems that everyone has to print one for some reason
09:08 AM sensille: if you're adventurous you can print an mpcnc with it
09:09 AM gregcnc: you know schaller bins? I think you could pay for a printer just by filling your toolbox with printed bins
09:27 AM Rab: gregcnc, I bet the filament costs more than the bins per equivalent unit.
09:27 AM Rab: And I bet the printed bins split apart if you load them with end mills or bolts or whatever.
09:27 AM gregcnc: except you can make them is sizes you actually want
09:28 AM Rab: I have no counter to this powerful argument.
09:28 AM gregcnc: prints aren't that bad people are flying printed model airplanes
09:28 AM Rab: People are flying styrofoam too.
09:43 AM justan0theruser is now known as justanotheruser
09:56 AM Loetmichel: *gaaaaa* wind10 shenannigans the Xth... $me sets .pdf standard app to "PDFX"... windows:Nope, wont do it! "We have found a problem with standard apps. Resetting .pdf to Edge." They REALLY want to annoy the sh** out of me!
09:57 AM Loetmichel: mind you: PdfX was running fine just when that message popped up!
12:01 PM * Loetmichel just went another 1/8 mile on his way home... have a strip of highway that starts at a traffic light and is straight and nearly flat. That car needs a service. :( Should be a bit faster for a 192hp 2001 BMW 525i touring. -> http://www.cyrom.org/palbum/main.php?g2_itemId=17640 I did it in 16.5 a while ago, but thats still not good (and i made no screenshot).
12:06 PM jym: Tired dogs... https://imgur.com/gallery/JNRCE
01:05 PM gloops: what does 'spindle override' do?
01:50 PM methods_: it lets you change the spindle feed from the programmed feed by a percentage
01:50 PM methods_: its usually used to adjust feedrate while running to get your "feeds and speeds" right
01:51 PM methods_: normally you'd use it when you're first setting up a part or if some tool was giving your issues
02:21 PM unterhaus: I'm trying to buy a scale for my acurite DRO. They don't have manuals listed under their part numbers
02:26 PM CaptHindsight: methods_: huh, I thought it was to test the speed at which the tool breaks
02:27 PM methods_: you can do that too
02:27 PM jym: CaptHindsight: !!!!!!
02:27 PM methods_: who let jym out again
02:27 PM jym: CaptHindsight: Tired dogs... https://imgur.com/gallery/JNRCE
02:27 PM methods_: :p
02:27 PM CaptHindsight: heh
02:27 PM * jym flings poo at methods_
02:28 PM * methods_ catches it and eats it
02:28 PM jym: SMF
02:28 PM CaptHindsight: methods_: they keep on trying to burn him out or leave him without power, he's invincible!
02:28 PM methods_: california strong
02:28 PM jym: CaptHindsight: Now, they are trying to snow me in
02:29 PM CaptHindsight: jym: they made weed legal here but sold out in a week
02:29 PM methods_: i hear california and oregon have plenty extra
02:29 PM gloops: methods thank you
02:30 PM methods_: np gloops
02:30 PM gloops: im assuming this depends on encoder feedback?
02:30 PM gloops: or maybe frequency
02:30 PM CaptHindsight: yeah, the feds won't let it get transferred state to state
02:31 PM methods_: it usually just increases/decreases your spindle speed by a percentage
02:31 PM methods_: feedrate override does teh same thing
02:31 PM gloops: right
02:31 PM gloops: ive got my slider at 100% but noticed it goes to 120%
02:31 PM methods_: using a combination of spindle/feed override you can usually find a sweetspot for running your tools at
02:32 PM gloops: makes sense now
02:32 PM CaptHindsight: one thing to watch out for with increasing the spindle speed is that it will keep the same override % for all movement
02:32 PM methods_: assuming you're in the ballpark already for your override amounts
02:32 PM methods_: if you're way off your overrides won't give you enough room to find a good speed/feed
02:34 PM CaptHindsight: so it might be great when your moving horizontal across a surface but not good for a vertical plunge
02:35 PM gloops: well, ive not been paying the spindle readouts much attention as having no probs with cutting (wood) but i have realised that the frequency is sitting at around 340hz - when im setting speed of 24k - the max
02:35 PM gloops: it should be close to 400 hz
02:35 PM gloops: will have to check the files out tommorrow
02:36 PM CaptHindsight: gloops: analog out to the VFD?
02:36 PM CaptHindsight: for speed control
02:37 PM gloops: yeah pwm
02:37 PM gloops: 0-10
02:38 PM gloops: maybe got the scale out
02:39 PM gloops: (not done anything with linuxcnc for ages so a bit rusty)
02:39 PM CaptHindsight: or check the 0-10V with a meter at 10V, if it's still at 340Hz then something is off in the VFD
02:40 PM gloops: yeah thats a good idea ill run that test tommorrow
04:22 PM Deejay: gn8
04:23 PM jym: Deejay: gn9
05:17 PM _unreal_: ve7it, hello
05:18 PM _unreal_: tonight is the last night of @#$@34 around with my daughters science fair project FINALLY
05:18 PM _unreal_: few things to finish and it will be done
05:21 PM _unreal_: ve7it, I just got my first few parts. got the resistor or cap smd pack maybe both I forget? I got my dspics today in the mail. and I just got the transformer
05:21 PM _unreal_: today
05:22 PM ve7it: perfect
05:22 PM _unreal_: GOD if we could just be done with this @#$@#$ school project
05:23 PM _unreal_: we ended up using my cnc machine just to do the drawing. and put the drawings onto her machine to model for the pictures for her project
05:23 PM _unreal_: there is just to much left to do
05:23 PM ve7it: we had a pile of snow up here the last few days.... was warm and windy overnight, so about 1/2 of it melted... about 6" left... glad I didnt have to drive anywhere
05:23 PM _unreal_: I prefer blackice my self
05:24 PM _unreal_: with a fresh dusting
05:24 PM ve7it: lurking blackice... traps the unwary
05:25 PM _unreal_: always fun
05:25 PM _unreal_: ve7it, I got my threaded rods turned as well
05:25 PM _unreal_: well all but Z
05:25 PM _unreal_: I have not built Z yet so I dont know how to mark it
05:25 PM _unreal_: :/
05:25 PM ve7it: yea... I saw that go by... how do they look?
05:26 PM _unreal_: they look wonderful
05:27 PM _unreal_: I wish I had the tools. I'd LIKE to take my coupler nuts and do a case hardening
05:32 PM _unreal_: I COULD just get it HOT and oil quench them.
05:32 PM CaptHindsight: science project built by dad? :)
05:33 PM _unreal_: more or less. even on paper it more or less should have SAID childrens science fair project FOR parents to complete
05:33 PM CaptHindsight: I helped my son build a toothpick bridge one ~8th grade...
05:33 PM _unreal_: My daughter decided to do her project on CNC machines
05:33 PM CaptHindsight: was used a s a model for the next several years since it held over 150lbs
05:34 PM _unreal_: because I'm building her one
05:34 PM _unreal_: its mostly complete
05:34 PM _unreal_: its just a "photo" prop right now
05:35 PM CaptHindsight: around the same time i think they had a save the egg from breaking contest
05:35 PM _unreal_: its amazing how much load a toothpick can take ;)
05:35 PM _unreal_: hehe
05:35 PM _unreal_: nothing works as well as foam peanuts
05:35 PM CaptHindsight: build a device to keep an egg from breaking when dropped from the school roof and kicked down 5 flights of stairs
05:36 PM _unreal_: ya its called hard boiled ;)
05:36 PM CaptHindsight: they had a list of banned components, styrofoam was included
05:36 PM _unreal_: bastards
05:36 PM CaptHindsight: heh, they made you crack the egg after he won to make sure it was still uncooked
05:38 PM CaptHindsight: gI think we used an polycarb or ABS box with the egg suspended by small bungies
05:39 PM CaptHindsight: egg in a cage with (foam filled), think they banned shave cream after that as well
05:40 PM CaptHindsight: science teacher ran out of stairs to kick it down
05:43 PM CaptHindsight: shaving cream or hail gel, forget what we used
05:43 PM CaptHindsight: hail/hair
05:43 PM CaptHindsight: is there hail gel?
05:44 PM jym: hair gel?
05:44 PM jthornton: Dippity-do lol
05:44 PM CaptHindsight: jym: yes the egg was suspended in a metal jar filled with gel
05:45 PM CaptHindsight: the jar was suspended by small bungies
05:46 PM jym: CaptHindsight: rainbow colored? cause that's important to know
05:46 PM CaptHindsight: lots of glitter
05:46 PM _unreal_: ve7it, msg
05:48 PM CaptHindsight: i think popcorn was also not on the list of banned materials
05:49 PM Tom_L: popcorn might be a little less predictable
05:50 PM CaptHindsight: thinking about it now we probably could have coated the egg in a flexible urethane, as long as you could still crack it after testing
05:51 PM CaptHindsight: genetically modified chickens that lay eggs with extra thick shells
05:55 PM jthornton: my buddy has some hens that lay really thick shelled eggs
05:55 PM CaptHindsight: are the more difficult to crack?
05:55 PM CaptHindsight: the/they
05:55 PM jthornton: yes
05:56 PM CaptHindsight: if you could get them to alternate the grain of the shells that would help
05:56 PM CaptHindsight: like plywood
05:56 PM CaptHindsight: then the chicks could not get out
05:57 PM ve7it: c section for chicks
05:57 PM jthornton: you would have to build stronger chicks
05:57 PM ve7it: knock 3 times when ready
05:57 PM CaptHindsight: jthornton: any bites on the mill yet?
05:57 PM jthornton: just spammers
05:57 PM jthornton: lol
05:58 PM CaptHindsight: yeah, takes me a week or two to get those to drop off
05:59 PM CaptHindsight: skunkworks: I saw that using NTP helped with latency on the pi4..
05:59 PM jthornton: I can't seem to get vlc installed on a rpi3 with a recent debian...
05:59 PM CaptHindsight: skunkworks: did you try playing youtubes in smplayer with the hardware codecs while running LCNC?
06:01 PM CaptHindsight: jthornton: no package or conflicts or??
06:02 PM jthornton: can't find it lol
06:02 PM CaptHindsight: I just started using Gentoo 64bit on the pi4 https://github.com/sakaki-/gentoo-on-rpi-64bit
06:06 PM jthornton: I've never seen Gentoo, what is it and how is it different than debian or others?
06:06 PM ve7it: back
06:08 PM CaptHindsight: jthornton: they tend to have better docs and you have to compile everything vs just install a binary package
06:08 PM CaptHindsight: the link above is a binary gentoo install so you can hit the ground running
06:09 PM _unreal_: forth
06:09 PM CaptHindsight: Gentoo is a completely custom install that you have to build, so you have to know what you are doing
06:09 PM jthornton: is it as minimal as OpenBox desktop?
06:10 PM CaptHindsight: minimal as no desktop
06:10 PM CaptHindsight: but the Gentoo image in the link ^^ is a complete install with lost of packages
06:10 PM CaptHindsight: lost/lots
06:12 PM jthornton: damn don't even remember poking a hole in my arm today but sure enough there is one
06:12 PM jthornton: https://www.youtube.com/watch?v=MlR3lZc2x9c
06:13 PM CaptHindsight: Chicken Fort Knox!
06:13 PM jthornton: aye, it's a must around here if you want to keep chickes
06:13 PM jthornton: chickens
06:15 PM CaptHindsight: jthornton: didn't you have a problem with dogs getting onto your property?
06:15 PM jthornton: yea the first group was killed by a dog... he didn't get to go home
06:40 PM Tom_L: is that in your newest shop?
06:42 PM jthornton: the old garden shed lol
06:43 PM jthornton: and the dog owner complained to my buddy I just took it to get his shots... I gave him some shots for sure
06:43 PM Tom_L: hard to keep track of all your buildings
06:43 PM jthornton: I know I get lost from time to time
06:44 PM jthornton: or I forget why I went to a building... and say crap why did I come here
06:45 PM Tom_L: i hear ya
07:24 PM Tom_L: jthornton, you got the new one all tech'd out too?
07:29 PM norias: howdy
07:39 PM SpeedEvil is now known as Guest65195
07:52 PM norias: haas has hsk spindles now
08:52 PM CaptHindsight: https://www.ebay.com/itm/Mag-Werkzeugspindel-Hsk-63-Uniflex-HSK63-Milling-Spindle-CNC-Spindel-D-1015-4492-/274085113671
08:52 PM CaptHindsight: is apparently unused with slight storage traces US $1,357.11
08:53 PM CaptHindsight: a bargain
08:53 PM CaptHindsight: I need to upgrade my Matsuura
08:53 PM norias: hmmm
08:53 PM norias: hsk63
08:55 PM CaptHindsight: there are a bunch of them on ebay
08:55 PM norias: nice
08:55 PM ziper: CaptHindsight, what kind of matsuura do you have
08:55 PM norias: if i were building a machine, that's what i'd want
08:55 PM ziper: a friend offered me one, I don't know anything about it
08:55 PM CaptHindsight: ziper: mc-710v
08:56 PM CaptHindsight: ziper: what model?
08:56 PM beachbumpete1: evening :)
08:57 PM CaptHindsight: ziper: https://www.ebay.com/itm/MATSUURA-MC-710V-2-Ram-Master-1-Yasnac-Control/303323528025
08:57 PM ziper: dunno, this is the only picture I have https://i.imgur.com/wVbo34r.jpg
08:57 PM ziper: he doesn't know the details and its a few hundred miles away
08:58 PM CaptHindsight: likely a 500
08:58 PM CaptHindsight: skunkworks has one
08:59 PM beachbumpete1: Matsuura make a great machine
09:00 PM beachbumpete1: parts are not too cheap I hear
09:01 PM CaptHindsight: lots of older units to cannibalize
09:01 PM beachbumpete1: thats true
09:01 PM CaptHindsight: the whole machine above is what $2500 or best offer
09:02 PM ziper: I need a shop
09:02 PM ziper: the car garage isn't cutting it
09:03 PM CaptHindsight: ziper: likely this model https://www.ebay.com/itm/Matsuura-RA-1-Vertical-Maching-Center-Year-1990/113811291209
09:04 PM CaptHindsight: but a new old stock HSK spindle for only $1500 with shipping
09:04 PM CaptHindsight: why bother rebuilding
09:04 PM ziper: christ 10k pounds
09:05 PM CaptHindsight: yeah
09:05 PM beachbumpete1: wish mine was that cheap
09:05 PM beachbumpete1: I am still trying to fix mine... :(
09:05 PM ziper: how hard is it to rebuild a spindle? do they typically have races are is the wear surface the spindle itself?
09:05 PM CaptHindsight: your bearings were as much or close
09:05 PM CaptHindsight: ziper: depends on what is wrong
09:05 PM beachbumpete1: yeah my brand new bearings were just over a grand
09:06 PM CaptHindsight: just bearings or needs to be reground and balanced
09:06 PM CaptHindsight: heh $15K for a rebuilt https://www.ebay.com/itm/REBUILT-HSK-SPINDLE-HSK-A100-WITH-PAPERWORK-AND-TEST-REPORT-MCM-LATHE/352509069653
09:07 PM CaptHindsight: some shop without rebuilding skills will eventually buy it
09:07 PM beachbumpete1: never thought I would enjoy 3D printing as much as I am
09:08 PM CaptHindsight: on the Formlabs or?
09:08 PM beachbumpete1: both
09:09 PM beachbumpete1: I use my tronxy X5SA-400 a lot more
09:09 PM beachbumpete1: the formlabs is at work
09:09 PM CaptHindsight: https://imgur.com/zvxoHUT 21 x 12" print area DLP
09:09 PM beachbumpete1: so mostly work stuff on that one
09:10 PM beachbumpete1: Thats a big LCD
09:10 PM beachbumpete1: does it work well?
09:10 PM CaptHindsight: uses a 4K dlp projector
09:10 PM CaptHindsight: https://imgur.com/zKNtBAg
09:10 PM beachbumpete1: Right now I am in the middle of a build of a 3D printed Electric Cello :)
09:11 PM CaptHindsight: working on the sand mold/core printers
09:11 PM beachbumpete1: what is that spinny thingy?
09:12 PM CaptHindsight: can have 16 4K projectors
09:12 PM CaptHindsight: a post-it on the z-axis screw :)
09:12 PM beachbumpete1: hehe
09:12 PM CaptHindsight: can check motion from several feet away
09:13 PM beachbumpete1: http://www.o-cello.com/
09:13 PM beachbumpete1: I am building one of these right now
09:13 PM beachbumpete1: thats a high tech solution hehe
09:14 PM CaptHindsight: how tall is it?
09:14 PM beachbumpete1: ya know I am not sure
09:14 PM CaptHindsight: pic needs a banana or similar for reference
09:14 PM beachbumpete1: but it is supposed to be a 4/4 cello size
09:15 PM beachbumpete1: It uses a 36 inch steel rod thru the middle that goes down to the aluminum foot rod if that helps any
09:15 PM CaptHindsight: 20cm sections, oh man on FDM, will be ready by summer :)
09:16 PM beachbumpete1: I gotta order my carbon fiber bow and strings, pickup, steel rods, etc..
09:16 PM beachbumpete1: actually I have most of it already printed
09:16 PM beachbumpete1: my machine is 400mmx400mm
09:16 PM beachbumpete1: I am printing like 10 parts at a time
09:16 PM CaptHindsight: https://www.filamentive.com/product/wood/
09:17 PM beachbumpete1: ya like that wood filament?
09:17 PM beachbumpete1: have not tried it yet
09:17 PM beachbumpete1: I plan to veneer the fingerboard with ebony veneer so it will feel more like a real cello
09:17 PM CaptHindsight: printed wood vs cnc carved from wood
09:17 PM beachbumpete1: the rest will be either plastic or painted not sure which
09:18 PM beachbumpete1: I hearthe wood stuff is nice tho.
09:18 PM beachbumpete1: Most of these guys are just using PLA
09:20 PM beachbumpete1: I am anxious to see how it sounds
09:20 PM beachbumpete1: there are tons of 3D printed electric violins that seems to work pretty well so I am optimistic this will be more of the same
09:22 PM ziper: beachbumpete1, that thing looks sweet
09:22 PM ziper: if I had any musical talednt i would try it
09:24 PM beachbumpete1: I think is is really cool design
09:24 PM beachbumpete1: I take guitar lessons and I play the keyboard a little bit. I have a small bedroom studio I goof around in.
09:24 PM CaptHindsight: $2000 vs $200,000 vs $700,000 Violin Bows https://www.youtube.com/watch?v=Yc91BW-KOgA
09:25 PM beachbumpete1: I love the way a cello can sound too
09:25 PM beachbumpete1: I know they are crazy what some of the bows cost
09:25 PM Tom_L: beachbumpete1, you ever finish machining the guitar?
09:25 PM beachbumpete1: the one I am getting is like $40
09:25 PM beachbumpete1: Tom_L: no man my machine is down
09:26 PM Tom_L: spindle?
09:26 PM beachbumpete1: yup
09:26 PM beachbumpete1: dont have another grand to throw at it right now
09:26 PM Tom_L: bearings never quieted down ehh?
09:26 PM beachbumpete1: have not been able to get the new bearings working ok
09:26 PM CaptHindsight: beachbumpete1: how did the bearing swap work out, last I recall you were starting to break them in
09:27 PM CaptHindsight: oh no
09:27 PM beachbumpete1: they are noisy for some reason and I cannot get them over like 2k without worry
09:28 PM beachbumpete1: I have to rip it down again and inspect but I have been so damn busy with work and my kid was in the hospital for almost a month
09:28 PM beachbumpete1: so things have been kinda crazy
09:28 PM beachbumpete1: then there was Christmas/holidays
09:28 PM CaptHindsight: ok now (the child)?
09:28 PM beachbumpete1: yeah she is fine thankfully
09:29 PM beachbumpete1: really sucks about my spindle bearings
09:29 PM beachbumpete1: Its like having a nice car you cant drive
09:30 PM CaptHindsight: I unfortunately know all the hospitals in the are too well for similar reasons
09:30 PM CaptHindsight: are/area
09:30 PM beachbumpete1: your kids have illnesses/issues
09:31 PM CaptHindsight: yeah, even when grown, memleak is still walking with cane after 6 months
09:31 PM beachbumpete1: memleak?
09:32 PM CaptHindsight: he does the RTAI work
09:32 PM CaptHindsight: https://github.com/NTULINUX/RTAI
09:33 PM beachbumpete1: This is one of your kids?
09:33 PM CaptHindsight: yeah
09:34 PM beachbumpete1: nice, sorry to hear about the cane, hope it heals well
09:34 PM CaptHindsight: 6 weeks is what they said back in August
09:34 PM CaptHindsight: hah
09:35 PM beachbumpete1: at least they expect it
09:36 PM beachbumpete1: Its funny I was working on the main body parts of this cello
09:36 PM beachbumpete1: and they are in like six different pieces
09:36 PM beachbumpete1: I was surprised how well they fit
09:36 PM CaptHindsight: a bit of an interference fit?
09:36 PM beachbumpete1: I need to deburr them and do a little sanding
09:36 PM beachbumpete1: yeah sort of
09:37 PM beachbumpete1: but they should go together reasonably well.
09:37 PM beachbumpete1: One of the makes talks about epoxying the pieces together once they are on the steel shaft
09:37 PM beachbumpete1: that sounds reasonable to me
09:38 PM CaptHindsight: that should hold them
09:38 PM beachbumpete1: and it will allow me to sorta putty the imperfections with some thick epoxy
09:38 PM beachbumpete1: the headless design is very nicely done
09:38 PM beachbumpete1: it uses Bass guitar tuning machines
09:39 PM beachbumpete1: and the pickup is for an acousting cello actually
09:39 PM beachbumpete1: fairly clever design honestly
09:39 PM _unreal_: beachbumpete1, back to the hospital dance again?
09:39 PM beachbumpete1: no thank God
09:39 PM beachbumpete1: she is home and doing great now
09:39 PM beachbumpete1: no more seizures or anything
09:40 PM beachbumpete1: back to school
09:40 PM beachbumpete1: she even rides her hoverboard
09:40 PM beachbumpete1: for awhile there I thought she was never going to be able to
09:40 PM beachbumpete1: for fear of having an episode and crashing etc
09:42 PM CaptHindsight: great that it's under control
09:42 PM beachbumpete1: yeah man
09:43 PM CaptHindsight: neurology is still a vast to be explored frontier
09:43 PM beachbumpete1: its funny you say that
09:43 PM CaptHindsight: wish there was more going on
09:43 PM beachbumpete1: they did every conceivable test on her for a month
09:43 PM beachbumpete1: and they STILL are not entirely sure WHY it was happening
09:44 PM beachbumpete1: the only thing good is that they found a medicine that stopped it
09:44 PM beachbumpete1: apparently most seizures can be sourced to their causes
09:44 PM CaptHindsight: been there
09:44 PM beachbumpete1: apparently not all the time
09:46 PM CaptHindsight: https://drive.google.com/file/d/19Icwb-fOron31ADhwb3RkyYShtNXt1Py/preview micro robot meets an Ameoba
09:47 PM CaptHindsight: have to get them 10-100x smaller to ride inside neurons
09:47 PM CaptHindsight: in and along
09:47 PM CaptHindsight: start mapping all this out
09:48 PM beachbumpete1: thats nutz
09:51 PM CaptHindsight: you can just about print one of those bots with a DLP printer
09:51 PM CaptHindsight: DLP and an inverse microscope
09:51 PM beachbumpete1: is the res that high on those now?
09:51 PM CaptHindsight: gets you down to couple microns geometry
09:52 PM CaptHindsight: http://ma.ecsdl.org/content/MA2012-02/59/3990.full.pdf#page=1&view=FitH
09:53 PM CaptHindsight: for under $1000
09:54 PM CaptHindsight: https://gmwgroup.harvard.edu/files/gmwgroup/files/757.pdf
09:56 PM beachbumpete1: interesting
09:56 PM beachbumpete1: that is a quite different machine than the larger format one you posted no?
09:56 PM CaptHindsight: so think of sensors that can fit inside and along cells and monitor activity, chemistry etc
09:56 PM CaptHindsight: report back or transfer data to outside sensors
09:57 PM beachbumpete1: how fast do you think your resin printer could make this cello?
09:57 PM CaptHindsight: yes, you use a DLP but rather than expand the image you use a microscope backwards and reduce the image
09:57 PM CaptHindsight: 100um/sec Z
09:57 PM beachbumpete1: These machines do not use wipers do they?
09:58 PM CaptHindsight: depends
09:58 PM beachbumpete1: our Form 2 is very cool
09:58 PM CaptHindsight: you can do continuous (layerless) prints
09:58 PM beachbumpete1: but damn that resin is messy
09:59 PM CaptHindsight: yeah, i have drums of it here
09:59 PM beachbumpete1: we bought the whole kit with cleaning stations etc
09:59 PM CaptHindsight: try not to get any on the floor
09:59 PM beachbumpete1: and it still seems to get everywhere
09:59 PM CaptHindsight: the worst is still white heat sink compound
10:00 PM CaptHindsight: you open a tube in one room and it will have left a smear on the backside of a drawer that is never opened in a room at the other end of the building
10:00 PM beachbumpete1: the print quality on the machine is quite impressive tho
10:00 PM beachbumpete1: hehehe
10:01 PM CaptHindsight: we have start making tini machines that make even smaller machines
10:01 PM CaptHindsight: tini/tiny
10:01 PM beachbumpete1: Once I get this cello finished and a few odds and ends prints I want to build I would like to explore more high quality FMD printing.
10:02 PM CaptHindsight: micro tools that make nanotools
10:02 PM CaptHindsight: that make nano machines
10:02 PM CaptHindsight: not much down at the small end of the spectrum
10:04 PM CaptHindsight: Intel is working on DNA synthesizers that aren't too small since they were worried about losing the DNA made in tool small a quantity
10:04 PM CaptHindsight: if the DNA factory sits on the head of pin the whole factory can get lost :)
10:05 PM CaptHindsight: how do you warehouse tiny tiny nano drops of DNA?
10:06 PM CaptHindsight: that is how I got into all of this
10:07 PM CaptHindsight: having kids at the doc and they have no clue to how things really work
10:07 PM beachbumpete1: https://i.imgur.com/1zCipzD.jpg
10:09 PM kanzure: CaptHindsight: any progress?
10:09 PM beachbumpete1: this is the knee rests, the electronics cabinet including the graphic equalizer and 1/4 inch jack/headphone jack, bridge and a few other bits and pieces.
10:09 PM CaptHindsight: kanzure: not holding my breath for anyone else to get much done
10:12 PM CaptHindsight: kanzure: I also avoid people that spin your wheels (all talk no action) :)
10:14 PM kanzure: *shrug* action is only where you look for it
10:18 PM beachbumpete1: goodnight
10:18 PM CaptHindsight: hasta
11:22 PM veegee: Adjusting the backlash on this mill is a pain in the ass
11:22 PM veegee: but at least I only have to do it once and it's pretty consistent through its movement range. not much wear in the center vs the edges
