12:09 AM Connor1 is now known as Connor
01:24 AM Valen: Those sorts of things aren't normally going to be paying the contestants more than an appearence fee at best
01:25 AM Valen: Also the stupid time constraints mean any minor screwup (which happens) will kill off any hope of doing a good job
01:33 AM roycroft: yes, and i get the minor screwups bit
01:33 AM roycroft: but making the blade outwith the stipulated parameters is automatic disqualification
01:33 AM roycroft: and they have tape measures
01:34 AM roycroft: quenching in water ruins the blade 80+% of the time
01:34 AM roycroft: and they know that
01:34 AM roycroft: yet they do it anyway
01:34 AM roycroft: those are the two "screwups" i don't understand
01:34 AM roycroft: which is what makes me wonder of those parts are staged
01:59 AM CaptHindsight: they seem to make those shows that appeal to people that enjoy watching drama and people that are stressed and uncomfortable
01:59 AM CaptHindsight: they aren't shows to pass on skill and knowledge
02:00 AM CaptHindsight: same for cooking shows
02:00 AM sensille: is it possible to get linear encoders for a reasonable price? my ebay-skills say 'no'
02:01 AM CaptHindsight: arrogant and condescending "judges" that seem to only want to belittle the cooks or craftsmen
02:02 AM CaptHindsight: hi I'm a pompous judge and I'm just going to mess with you
02:03 AM CaptHindsight: sensille: glass encoders?
02:03 AM sensille: yes
02:03 AM Loetmichel: mornin'
02:04 AM gloops: 3 sided corbels on a 3 axis router, 5 times the fecking about
02:04 AM CaptHindsight: sensille: http://www.dropros.com/
02:05 AM gloops: first cut https://ibb.co/d6BPXNt
02:05 AM CaptHindsight: Loetmichel: are you still experiencing north africa temps?
02:06 AM gloops: i now have to flip that to machine the 2 other sides, picking the profile up perfectly of course
02:06 AM sensille: CaptHindsight: thanks
02:06 AM gloops: the model is about as square as if it were made with breast silicone
02:08 AM Loetmichel: CaptHindsight: nope, pretty mellow now, ~20°C this morning
02:08 AM Loetmichel: *uuups* pinted a few parts yesterday, one of the two ender3s -> Spool empty... so i stopped the print.. came back to the company this morning: one printer finished and cool, the other had extruder and bed on PLA temps all night :-( Should have switched it off after stopping the print :-(
02:10 AM CaptHindsight: sensille: do you consider those prices reasonable?
02:16 AM sensille: they do look quite a lot like the chinese ones. are they any better? if the accuarcy is comparable to heidenhain then the prices are very reasonable
02:16 AM sensille: my dream is to get genuine heidenhain from someone who doesn't know what he's selling :)
02:18 AM gloops: some used for sale in the states
02:19 AM gloops: https://www.ebay.co.uk/itm/30-Futaba-Pulscale-digital-linear-encoder-scale-SB601A/123860395132?
02:20 AM CaptHindsight: sensille: US sales and warranty
02:20 AM CaptHindsight: 1um is 1um
02:21 AM gloops: Futaba is expensive
02:22 AM CaptHindsight: nothing personal, but I doubt you're building anything any more precise than these
02:22 AM sensille: +- 10um it says
02:24 AM sensille: that's not completely out of reach
02:24 AM * Wolf__ is perfectly happy with his cheap china dro https://www.aliexpress.com/item/32789719488.html
02:25 AM CaptHindsight: I build things that are more precise but it all temp controlled or measured by a laser over temp
02:27 AM sensille: Wolf__: the scales seem to be the same as dropros
02:27 AM Wolf__: yup, just less support if you need it
02:30 AM CaptHindsight: lifetime Chinese warranty or good luck finding us, whichever comes last
02:30 AM sensille: :)
02:32 AM Wolf__: Siton tech I found mentioned on a bunch of home shop forums, figured why not, even if something dies in the kit the original cost + replacement was still way under US based resellers
02:40 AM CaptHindsight: https://www.shars.com/products/measuring/digital-readouts-dro?dir=asc&order=price
02:41 AM sensille: those easson scales come with an accuracy report. as it is chinese, the question is: are they real?
02:43 AM Wolf__: I look at it this way, probably accurate enough for my mill with what I’m doing, if I needed true report and traceable cert I would be expecting to pay for that…
02:44 AM CaptHindsight: I only buy components to impress my dates
02:44 AM CaptHindsight: if 1um glass scales aren't enough for them, they are probably too high maintenance anyway
02:45 AM Wolf__: =D lol
02:45 AM sensille: :)
04:53 AM Loetmichel: *giggle* just got a Laerprinter delivered to repair it... opened the box: "hmm, shouldnt that thing be WHITE, not black?" ... seemms the parcel service played a bit of football with the package ;) *$me whips out the toner vacuum*
04:54 AM XXCoder: lol
05:05 AM Tom_L: morning
05:10 AM jthornton: morning
05:10 AM XXCoder: morning
05:11 AM XXCoder: Loetmichel: talking about black, I got order of black 2.0 lol
05:11 AM XXCoder: and evenually black 3.0
05:12 AM Loetmichel: thats that nano stuff that absorbs 99,99% light?
05:12 AM XXCoder: nothing gets 99.99%
05:12 AM XXCoder: vantablack is at 99.6%
05:13 AM XXCoder: black 2.0 is at 96% and black 3.0 is 99%, but both is easy to use
05:13 AM XXCoder: just paint
07:17 AM Loetmichel: XXCoder: interesting
07:17 AM XXCoder: oh yes forgot to say this: vantablack is very special material. you cant touch it
07:18 AM XXCoder: frankly black 3.0 is good enough. heck, 2,0 is in many cases.
07:18 AM Loetmichel: it needs to be applied by vacuum deposition iirc?
07:18 AM Loetmichel: vanta black i mean
07:18 AM XXCoder: theres also spray can of it but loses some matte
07:18 AM XXCoder: 99.3% I think
07:18 AM XXCoder: very expensive
07:18 AM * Loetmichel remembers using a candle to soot the inside of telescope tubes
07:19 AM Loetmichel: back in the day
07:19 AM Loetmichel: worked pretty well
07:19 AM XXCoder: ah yeah soot was very dark
07:19 AM XXCoder: not quite to level of those but yeah
07:19 AM XXCoder: ultracheap
09:21 AM Deejay: hi
09:23 AM JT-Shop: hi
10:23 AM * SpeedEvil thinks of the discovery of purest green.
10:29 AM perry_j1987: morning all
10:44 AM jym: goooooooooooood morning vietnaaaaaam!!!
10:48 AM jym: Oh man, the marinating chicken smells *SO* good <drooling>
10:59 AM norias: hi...
10:59 AM norias: i found the tool table file...
10:59 AM norias: but does anyone know where the file for the atc is?
10:59 AM norias: and what the name is?
11:03 AM jym: norias: ThisS?
11:03 AM jym: norias: This??? https://forum.linuxcnc.org/10-advanced-configuration/31754-how-to-build-atc-carousel-in-linuxcnc
11:06 AM norias: i'll poke through there
11:06 AM norias: i'm starting to think the atc just puts it's info in the tool table
11:06 AM norias: interesting that the linuxcnc tool table doesnt have wear data
11:07 AM norias: yeah, i think it's in the tool table
11:08 AM norias: but what you shared will be handy if i eventually make a different atc
11:12 AM jym: norias: Can just google "linuxcnc blah"
11:13 AM norias: yeah
11:13 AM norias: thanks
12:11 PM perry_j1987: hmm can fusion 360 apply texture to a model or do i need to look into blender
12:59 PM selroc: hi pink_vampire, sumpfralle2 and all
02:10 PM Loetmichel: gnihi, you can see in the background that even if you load the same file at the same time into to identical 3d printers and have them settings copied they STILL get out of sync: https://www.youtube.com/watch?v=VBb6vFMjX5M
02:10 PM Tom_L: friction
02:11 PM unreal_ is now known as Guest39449
02:28 PM gloops: how did the grapes carving tuen out unreal_ ?
02:32 PM jym: Loetmichel: and how was that in real time?
03:57 PM Deejay: gn8
04:07 PM unreal_ is now known as Guest88066
05:09 PM Tom_L: andypugh, back from Spain?
05:11 PM jthornton: hmm my grass I planted in the woods is growing :)
05:12 PM Elmo40: Loetmichel, how is the print started on each printer?
05:12 PM Elmo40: plus, is accel the same on both printers?
05:15 PM Tom_L: ok, garage is finally cleaned out of basement stuff
05:15 PM jthornton: stuff you had to toss?
05:15 PM Tom_L: mowed and spent the rest of the afternoon breaking down boxes
05:15 PM Tom_L: sorted it out yes
05:15 PM jthornton: got the last piece of siding up this afternoon
05:15 PM Tom_L: kept some, tossed some
05:16 PM Tom_L: well, good to hear! come on over...
05:16 PM jthornton: I bush hogged the trails I have through the woods dang it was 2' high
05:16 PM jthornton: not done lol got to caulk, paint etc...
05:17 PM jthornton: need to finish the gutters after that then move on to the next wall
05:17 PM pcw_mesa: CaptHindsight: http://freeby.mesanet.com/xy100.zip
05:19 PM jthornton: yea it's Friday and quitting time, the boss is not looking so I'm done working for the day
05:19 PM pcw_mesa: 7i92 config with standard 5Axis BOB on P2 and XY100 + DPainter on P1 (inboard connector)
05:19 PM Tom_L: same here. just showered and plans are to do nothing
05:48 PM Elmo40: for me it has been beer-o-clock since noon ;-)
05:51 PM justan0theruser is now known as justanotheruser
06:35 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20190802_161629.jpg
06:35 PM skunkworks: Should we take bets on how long until I actually etch a panel for this?
06:36 PM jym: Food porn https://i.imgur.com/3xuzdKq.jpg (just finished making that an hour ago)
06:36 PM Tom_L: maybe after the numbers rub off a few times
08:13 PM CaptHindsight: pcw_mesa: thanks, got it
08:15 PM CaptHindsight: jym: chicken or trail findins?
08:15 PM jym: chicken satay
08:18 PM justan0theruser is now known as justanotheruser
08:25 PM perry_j1987: been watching all the vids from KiCon
08:25 PM perry_j1987: wish i could have made it
08:48 PM roycroft: indexing all three tables on my mill took a very long time, but i'm there now
08:49 PM XXCoder: yay
08:49 PM roycroft: i was going to make one of my parts tonight, but it took me a couple hours to get the mill set up
08:49 PM roycroft: the two x tables are parallel to within less than a tenth now :)
08:50 PM roycroft: it is time to make dinner though, so i'll make parts in the morning
08:50 PM XXCoder: yummy
08:51 PM XXCoder: you sharing?
08:51 PM roycroft: sure, come on over
08:51 PM roycroft: i'm not sure what i'm going to make yet though
08:51 PM XXCoder: eh not worth plane ticket lol
08:51 PM roycroft: i have to go to market and see what looks good and fresh
08:51 PM roycroft: i'm weary - i went in to work at 6 again this morning
08:51 PM roycroft: so i might just make pasta or nachos or something simple like that
08:52 PM XXCoder: :)
08:52 PM XXCoder: ever tried pototo salad burrito?
08:52 PM roycroft: if there's some nice looking fresh salmon i might do some grilling
08:52 PM roycroft: no
08:52 PM XXCoder: replace meat with pototo salad
08:52 PM roycroft: i have had breakfast burritos with potatoes in them
08:52 PM roycroft: potatoes, eggs, onions, beans
08:52 PM XXCoder: add hot sauce, cheese, small amount of sour cream
08:52 PM roycroft: and cheese, of course
08:53 PM XXCoder: some plants stuff. cold and yummy. perfect for hot days
08:53 PM roycroft: so interestingly, i found that bumping the upper x-y table to get it parallel to the lower one was rather tricky
08:53 PM roycroft: i ended up bolting it down hard on the rotary table
08:53 PM roycroft: and moving the rotary table a few minutes to get it dialedin
08:54 PM roycroft: then i just reset the index dial on the rotary table to zero
08:54 PM roycroft: i should have figured that out earlier on - it would have saved me a fair amount of frustration
08:55 PM XXCoder: nothing like doing it to learn it
08:55 PM roycroft: yes
08:55 PM roycroft: next time it will take half the time to set up
08:55 PM roycroft: this is why i did a complicated setup for my first rotary table job
08:56 PM roycroft: it will make simple jobs a lot easier
08:56 PM roycroft: and i won't be intimidated by a complicated setup again
08:56 PM XXCoder: :)
08:56 PM roycroft: at least, in my mind, this was a complicated setup
08:57 PM roycroft: maybe others think it's standard fare
08:57 PM roycroft: but i'm not a real machinist, so my perspective is different
08:58 PM roycroft: i even drew arrows on all the dials so in the morning when i forget which direction i indexed them i'll still be able to figure it out :)
08:59 PM Tom_L: <---->
08:59 PM roycroft: that would be the arrow for a zero backlash lead screw
09:00 PM roycroft: my ancillary x-y table has about 0.020" backlash after i tuned it up
09:00 PM roycroft: it was more like 0.060" when i started
09:01 PM roycroft: the jigs i'm making are for routing some wooden parts, so i'm going overboard on accuracy already
09:01 PM roycroft: but it's the learning experience that is most important to me on this project
09:01 PM roycroft: the jigs are almost just a bonus
09:02 PM * roycroft heads off to market to see what piques his taste buds this evening
09:03 PM XXCoder: man
09:03 PM XXCoder: I want shop :(
09:24 PM _unreal_ is now known as unreal_
09:40 PM infornography: ..do you think this would mill aluminum?
09:42 PM infornography: https://www.ebay.com/itm/US-DIY-3040Z-CNC-Router-Frame-Milling-Machine-Ballscrew-Kit-w-300W-DC-Spindle/273943448160?hash=item3fc84d4a60:g:91IAAOSwWs9dOUVn
09:46 PM XXCoder: finally a link heh
09:46 PM XXCoder: would say yes, carefully
09:49 PM roycroft: there is not much z on that thing
09:49 PM infornography: Do you think the ballscrew would have any benefits on that style of machine? I can find complete machines in about the same brice range without the ballscrew.
09:49 PM roycroft: i wouldn't call it a mill by any stretch of the imagination
09:49 PM roycroft: it is a router
09:49 PM roycroft: and can probably do light aluminium stuff
09:50 PM infornography: *price*
09:53 PM roycroft: that entire machine costs less than the cost of a single decent quality ball screw
09:53 PM roycroft: crappy ball screws are no better than acme screws
09:53 PM XXCoder: depends on user case. i wouldnt use that for close tol parts
09:58 PM roycroft: a cheap ball screw will usually have lower friction than an acme screw, which allows you to use smaller motors on the machine
09:59 PM roycroft: but a cheap ball screw may not be as accurate as a well-made acme screw
09:59 PM roycroft: there are no easy answers to your questions :)
09:59 PM XXCoder: indeed
10:00 PM infornography: fair enough
10:00 PM roycroft: that listing states clearly that it is not for milling
10:01 PM roycroft: it's an engraver
10:01 PM roycroft: which means light 2d work on sheet goods
10:02 PM roycroft: if you want to do actual milling of non-ferrous metals something more like a grizzly g0704 with a cnc conversion is what you should be looking at
10:14 PM infornography: https://www.ebay.com/itm/CNC-2417-USB-Desktop-Metal-Mini-Engraver-PCB-Milling-Machine-DIY-Mill-Router-Kit/182890439400?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D57921%26meid%3Dc2bfc94f4f3045fba24ceaf35faf8a6d%26pid%3D100005%26rk%3D6%26rkt%3D12%26sd%3D273943448160%26itm%3D182890439400%26pg%3D2047675&_trksid=p2047675.c100005.m1851#rwid
10:14 PM infornography: LOL Endorsed by Santa!
10:14 PM XXCoder: makes sense
10:15 PM XXCoder: makes toys on it
10:15 PM XXCoder: totally.
10:16 PM roycroft: santa?
10:17 PM roycroft: don't you really mean SATAN?
10:23 PM pcw_home: Satan Claws?
10:24 PM roycroft: well isn't that special
10:25 PM XXCoder: https://i.pinimg.com/originals/0c/b7/fa/0cb7fa331c42c08034a855825a1bcd4c.jpg
10:26 PM XXCoder: orginial http://anotherwebcomic.com/letters_to_satan
10:27 PM XXCoder: very related http://anotherwebcomic.com/santas_souls lol
10:33 PM roycroft: https://www.youtube.com/watch?v=YHyW0N5f7zQ
10:35 PM infornography: lulz
10:47 PM roycroft: and another forged in fire contestant made a blade that was too big
10:47 PM roycroft: he even measured it a half dozen times before turning it in
11:00 PM XXCoder: heh watched that series yeah I remember that one
11:07 PM Wolf__: heh I sorta know someone that was forged in fire
