12:08 AM rue_shop1: anyone here made an EDM supply?
12:25 AM rue_shop1: ok I think I should have switched bits and just used the 1.5mm for the 2mm slot...
01:45 AM Deejay: moin
01:46 AM rue_shop1: morning
01:46 AM rue_shop1: heh, I set the finishing pass for the same dep/pass as the initial cut, I bet I end up with the same marks
02:51 AM veegee: any way to purify the exhaust from the propane forklift while using indoors?
02:51 AM veegee: CaptHindsight ^? Not sure if they come with a catalytic converter
02:52 AM veegee: but I'm thinking of putting something on there to filter the particulate matter at the very least
02:52 AM veegee: I'm not worried about CO or CO2, I have sensors to monitor content
02:53 AM veegee: And you can recover fully from CO poisoning
02:53 AM veegee: I don't want particulate matter clogging my lungs and potentially causing some kind of cancer
02:54 AM veegee: Also gas diffusion is pretty fast and I'll have forced ventilation. Particulate matter tends to get everywhere, settle on surfaces, etc.
02:56 AM XXCoder: vee hose to outside?
02:56 AM XXCoder: dunno lol
02:56 AM XXCoder: forced air of course
02:59 AM CaptHindsight: afterburner

05:11 AM jthornton: morning
05:13 AM XXCoder: yo
05:40 AM htasta: hey hou, I'm setting up my 7i76e and used Pncconf for that, I set all motors max velocity to 3000mm/min but when I open axis I only get 1500mm/min. Is there another setting I have to change in order to get the 3000mm/min?
05:41 AM jthornton: I don't think anyone here uses pncconf
05:42 AM htasta: lol ok.
05:42 AM jthornton: might be time to look at your ini file
05:43 AM htasta: yeah I can find it in the ini obviously but I was curious if I can set it in the pncconf
05:43 AM jthornton: ask on the forum in the pncconf section
05:47 AM htasta: lol I found it, it's an axis setting. strange that the axis setting is not set to the highest value of the motors.
05:47 AM htasta: but pncconf seems to do weird stuff anyway, it set my limits to -0.01mm but I entered 0.0
05:48 AM jthornton: not really strange as joints might have a higher speed than an axis and yea it's strange
05:48 AM htasta: so not strange for 1500mm/min but strange for -0.01? :D
05:50 AM jthornton: a do all program like that must be a nightmare for Chris to keep up with I know I've written some configuration tools for Linuxcnc
05:51 AM htasta: haha yeah that's very true
05:52 AM htasta: do you happen to know if I can have longer dir hold and dir setup times than 10us with the 7i76e?
05:52 AM jthornton: I don't see why not
05:53 AM htasta: cuz pncconf doesn't let me :D
05:53 AM andypugh: Do you need it? They don’t normally need to be very ling.
05:53 AM andypugh: (long)
05:53 AM htasta: I had my machine run with parallel port before and it ran "fine" with 5,5 and 20,20
05:53 AM andypugh: But, yes, you can edit the numbers in the INI (or possibly the HAL, depending on how pncconf sets it up)
05:54 AM htasta: I had one axis run with 4500mm/min there and it never stopped (dunno if that was what caused me to get bad lengths on parts)
05:54 AM htasta: now I set it to 4500mm/min and it stopped the motor pretty quickly
05:54 AM htasta: but the dir times are the same 5;5 so I'm confused a little haha
05:56 AM jthornton: it really depends on the stepper drive timing requirements
06:00 AM htasta: sadly I don't know them, they depend on a cap and I don't know the value of that cap, but I haven't put much time into researching that. maybe it's time now to dig into that :D
06:01 AM jthornton: http://linuxcnc.org/docs/2.8/html/config/stepper-diagnostics.html#_testing
06:06 AM htasta: yeah I tested them when using the pport and I jerked around on the moving thing to "simulate" a load and it did 4500mm/min fine. now without jerking just load free it stops, so something else has to be fucky :D
06:18 AM rs[m]2: htasta: realistic acceleration setting is very important for stepper systems. acceleration too high -> motor stalls
06:18 AM htasta: I set it to 10us;10us now it it seems to work, nice time to run the test you linked. :D
06:19 AM htasta: rs[m]2: I set it to 250mm/sec^2
06:19 AM htasta: is that high or low? :D
06:19 AM htasta: the pncconf default was 750mm/s^2 but I guess that's for good machines not mit cheap chinese 6040 haha
06:21 AM jthornton: https://dpaste.com/BQY7JYBJL my X axis on my plasma table
06:22 AM jthornton: for example... also note the power supply for the drives is 63vdc and voltage = speed
06:23 AM htasta: thx for the example, the units are inches, right?
06:23 AM jthornton: aye
06:30 AM htasta: ok, it had to be something else, I set it to 5us in the ini now and it still works, so it has to be some other setting that the pncconf changed to make 4500mm working. i set the 4500mm in the ini before = error and after 4500mm in the pncconf it works even when setting the set times to 5us in the ini
06:31 AM htasta: yeah I guess I have to do some more reading on the ini and which settings influence stuff :D
06:38 AM htasta: thx for the help guys, imma do some testing now after walking the doggo :þ
06:54 AM Tom_L: morning
07:04 AM miss0r: morning
07:22 AM jthornton: morning
07:24 AM jthornton: I wonder why caja thinks a .ngc file is a Neo-Geo Pocket Color ROM?
07:33 AM jthornton: dumb it thinks that if you use %%
08:43 AM jymmmm: morning
08:48 AM jymmmm: Interesting.... IF you are 70 or older, the DMV has automatically extended your drivers license one year past it's expiration.
09:44 AM foadsf: Hello everyone, I have also created a #linuxcnc channel on our Discord server https://discord.gg/YSvyrZq . the server was initially created for Elmer FEM, but now is hosting many other CAD/CAM/CAE FLOSS out there including #freecad #salome #solvespace #caelinux ... and many other. it will be great to have you guys also over there
09:48 AM rs[m]2: hmm. joined discord, fan begins to spin
09:48 AM foadsf: nice to have you over there ;)
09:49 AM rs[m]2: closed again, fan stops spinning
09:49 AM rs[m]2: foadsf: sorry that would drain my battery. don't know what discord is doing, as there doesn't seem to be all that much activity, but it pins one CPU
09:49 AM rs[m]2: just sitting there
09:52 AM foadsf: well, Discord app is a bit resource hungry. I suggest that you install the mobile app https://discord.com/download if you want to stay in touch with the community
09:53 AM rs[m]2: mobile app on the pc?
09:54 AM Tom_L: thanks but i'm fine right here
09:56 AM rs[m]2: foadsf: matrix works quite well for people that are afraid of "real" IRC clients, and you can use it to talk in #freenode irc channels
09:57 AM foadsf: I think you need a personal server for that. Am I wrong?
09:57 AM Tom_L: i've used it a little in the past
09:57 AM Tom_L: no server needed
09:58 AM rs[m]2: no personal server needed, but you could use your own if you wanted to
09:58 AM foadsf: any instructions? So it acts like a IRC client?
09:59 AM Tom_L: i wasn't given any
09:59 AM rs[m]2: it has a bidirectional gateway / mirror built in
09:59 AM rs[m]2: so each matrix user has its separate irc nick
10:00 AM Tom_L: shows up here with an [m] by the name as you can see
10:00 AM jymmmm: Uh, just use the webcaht??? https://webchat.freenode.net/
10:00 AM Tom_L: some like pics etc gettin in the way
10:00 AM rs[m]2: foadsf: https://matrix.org/bridges/

10:03 AM Tom_L: https://gist.github.com/fstab/ce805d3001600ac147b79d413668770d
10:04 AM Tom_L: #hazzy uses it alot
10:04 AM Tom_L: (qtpyvcp channel for linuxcnc gui)
10:05 AM jymmmm: telnet://irc.freenode.net 6667
10:05 AM Tom_L: bbs
10:05 AM jymmmm: teletype
10:05 AM Tom_L: smoke signals
10:06 AM Tom_L: you got plenty o that
10:06 AM jymmmm: morse code
11:07 AM _unreal_: hello
11:09 AM Rab: _unreal_, sup
11:10 AM Rab: Here's another artist being flung around by a robot arm: https://www.youtube.com/watch?v=Xn813NKlhzI
11:11 AM Rab: Hopefully faked, it looks pretty unsafe.
11:15 AM _unreal_: hi
11:16 AM _unreal_: the motoman is clearly animated
11:17 AM _unreal_: the sinking between the body and the "" attachment"" clearly are rough
11:18 AM Rab: _unreal_, there are a couple scenes where it drags her or picks her up where I couldn't see an actual attachment method.
11:18 AM Rab: _unreal_, what can you tell me about polishing starboard?
11:19 AM _unreal_: use high grit sandpaper
11:19 AM _unreal_: define polish? are you taling shiny mirror?
11:19 AM _unreal_: talking
11:19 AM _unreal_: or just smooth no micro hairs
11:19 AM _unreal_: ?
11:19 AM Rab: Just smooth to the touch. Yeah, that.
11:19 AM Rab: Tried flame polishing?
11:19 AM _unreal_: then just sandpaper
11:20 AM _unreal_: STARBOARD does not polish well for long
11:20 AM _unreal_: doesnt wear much ether but wont hold a shiny polish
11:20 AM Rab: Makes sense.
11:20 AM _unreal_: your likely looking for an 800-1k grit finish
11:21 AM _unreal_: so
11:21 AM _unreal_: 120, 220, 400, 600-800 and finish with 1k grit
11:21 AM _unreal_: you wont need to go any higher then that
11:21 AM _unreal_: also
11:21 AM _unreal_: when you get to the 400+ your likely going to want to use wet sand paper
11:21 AM Rab: I was going to try it for some custom bathroom shelves. But it seems like if it has a rough finish, it'll be impossible to keep clean once dirt gets in the surface.
11:22 AM _unreal_: starboard will mildo like a MOFO in a bathroom IF its not very smooth
11:22 AM _unreal_: but you can bleach clean it nicely
11:22 AM Rab: _unreal_, hmmmm, maybe it's a bad idea then.
11:22 AM _unreal_: I'm not going to say that
11:23 AM Rab: I guess I could always try it, then replace with painted wood if it doesn't hold up. :P
11:23 AM _unreal_: its litteraly designed for the marine industry
11:23 AM Rab: yah
11:23 AM _unreal_: I'm just saying scratches will mildew
11:24 AM Rab: I guess there is danger in having an exposed surface that will degrade if someone uses an abrasive cleanser.
11:24 AM _unreal_: I guess a better way to think of it is like a cutting board that has knife score lines that are black with deeply embeded mildew
11:24 AM _unreal_: thats what you have to be careful of
11:24 AM Rab: _unreal_, yeah, that's what I was envisioning.
11:25 AM _unreal_: as to mounting it. is it going to go into a shower?
11:25 AM _unreal_: or just in the bathroom?
11:25 AM Rab: _unreal_, in the bathroom above waist height. So not a wet location per se, just a humid one.
11:25 AM _unreal_: then you have NOTHING to worry about
11:26 AM Rab: Think small shelves next to the mirror.
11:26 AM _unreal_: part of the reason why lots of stuff in showers are typically ceramic or fiberglass
11:27 AM _unreal_: and super smooth is to cut down on the mildew. because the surfaces are "" super smooth""
11:27 AM Rab: Cool, I'll move forward. Know of a cheap source for 1" starboard?
11:27 AM _unreal_: ehhhh
11:27 AM _unreal_: your in cali right?
11:27 AM Rab: Texas
11:27 AM _unreal_: your in texas right
11:27 AM _unreal_: hehe
11:27 AM _unreal_: home depot, lowes has it
11:32 AM _unreal_: amazon
11:32 AM _unreal_: ebay
11:32 AM _unreal_: ebay will likely be the cheapest. you can find lots of it at "west marine" stores and PAY OUT THE FUCKING ASS
11:32 AM Rab: Nearest port is Galveston, not much yacht culture. ;)
11:32 AM Rab: I'll bet.
11:32 AM renesis: rab: the crushable parts looked edited like they could be fake
11:32 AM _unreal_: if there are marina's year you there is a chance you could get scraps cheap
11:32 AM Rab: I found a supplier, might be Tap Plastics, which beat eBay by $10 or so for the 12x12" sizes I wanted.
11:32 AM renesis: the flinging parts look hard to fake without using something else as dangerous
11:32 AM _unreal_: rab as I said you can do all kinds of amazing stuff with it.
11:32 AM Rab: renesis, any real footage might have been sped up, too, with choreographed "whiplash" moves.
11:32 AM _unreal_: ball end bits make amazing finishes if your doing rounds.
11:32 AM renesis: rab: its not much safer like that
11:32 AM renesis: robot could still flip out and smash her into the floor
11:32 AM Rab: _unreal_, I was gonna try a corner routing bit for a bullnose, but I'm not sure my CNC router has enough torque for that.
11:34 AM renesis: maybe they captured her motion with cable rigging and pneumatics, seems a lot more like accepted movie stunt tech
11:34 AM Rab: The track looks insubstantial. I assume if it's real, it's seriously anchored. But if they can fake any of it, they'd probably fake all of it.
11:34 AM renesis: right
11:35 AM renesis: the parts where shes on the floor and it grabs her on the back look faked
11:36 AM renesis: those are the parts that scare me the most, tho, even with tested choreography
11:36 AM Rab: My Oakland homies have this thing. I really don't feel like they respect its capabilities. https://sudoroom.org/wiki/Giant_robot_arm
11:36 AM renesis: is power was lost while accelerating towards her, would punch her into the ground
11:37 AM Rab: They might have it anchored now. Notice how it's just sitting on a pallet in the pic.
11:37 AM renesis: ha, yeah and thats a little motoman
11:37 AM renesis: last job they had cells with ones like twice that size
11:38 AM renesis: theres fences, but seems like the thing could chuck a bigass casting over the fence pretty easy if it wanted
11:39 AM renesis: as if the forklifts racing around and overhead cranes everywhere wasnt enough to be paranoid about
11:41 AM _unreal_: rab this is being interesting.
11:41 AM renesis: rab: re: your comments below, bot makes have their own languages and abstracted XYZ motions
11:42 AM _unreal_: so my daughters cnc machine is "working" I still need to mill the parts out to make the primary pen/spindle/laser mount
11:42 AM Rab: It moves fast if it wants to. I "broke" the controller by putting in point A to point B moves that fell within max combined velocity, but exceeded individual speed of the joints involved so it errored out. That was educational. (And hopefully that was corrected in the last 25 years.)
11:42 AM renesis: figuring out the motions is a lot of trig and matrix math
11:42 AM _unreal_: its only going to have but its at least moving
11:42 AM renesis: rab: how broke?
11:42 AM _unreal_: right now I'm trying to get her to start reading and LEARN what her machine does and how to make it work
11:47 AM Rab: renesis, firmware error that persisted after restart, which seemed pretty weird. IIRC we had to re-load the firmware from floppy disk or some shit, then it was fine.
11:49 AM Rab: I'm sure there's a proper method to clear the problem, but we were all far from being Yaskawa experts.
11:50 AM renesis: that sucks
11:51 AM Rab: But the experience left me feeling that there should be an automated bullhorn to scream at everyone to vacate the arm's work envelope if they want to live.
11:51 AM renesis: sounds like maybe it tried to do something and physics said no and it didnt forget what it tried to do
11:51 AM renesis: um
11:51 AM renesis: thats kind of standard for these things when theyre moving
11:52 AM renesis: if youre within the envelope, there should be interlocked stops keeping it from doing anything
11:52 AM renesis: the whole safe co-op bot thing scares me
11:52 AM Rab: Haha, no interlocks, just a wooden pallet.
11:53 AM renesis: right, so i definitely got your back on the whole not respecting its capabilities
11:54 AM Rab: I think it's been just for show in recent years.
11:54 AM renesis: some distributor sales guy tried to sell me on having a 6 axis bot working alongside line workers, i didnt respond because inside i was like JEZUS FUCK ARE YOU MAD
11:55 AM renesis: work maybe cuts some corners, but least theyre good about sticking guards on everything
11:56 AM renesis: like, tiny cylinder can pinch a pinky on retract? it gets the acrylic shielding
11:58 AM renesis: they complained a bit when i showed how two button activate wasnt safe, because it was positioned where it was easier to activate with elbows than hands, with hands in crush points
11:58 AM renesis: "THEN THEYRE NOT FOLLOWING WORK INSTRUCTION" which would be an argument for disabling all the safety shit
11:58 AM renesis: but they changed it
11:58 AM Rab: heh, yeah
11:59 AM Rab: Did they reposition the buttons, or put hoods on them?
11:59 AM renesis: DID THEY NOT FIRE THAT GIRL? like wtf her supervisor is the one that showed us she was faster doing it like that
11:59 AM renesis: i repositioned them out to the sides
12:00 PM renesis: so it was closer to the machine, but not possible to elbow them, maybe not intuitive, was faster tho besides safer
12:00 PM renesis: using flush buttons probably would have worked
12:01 PM renesis: but if the buttons were replaced later, they would prob just use what was available
12:01 PM renesis: and they usually use mushrooms for fast slappability
12:01 PM Rab: I operated one of these when I was a teenager, it left me a believer in two-button activate. https://www.wirebids.com/lots/view/polar-mohr-115-ce-paper-cutter-w-microcut-programmer/15262
12:02 PM renesis: i also defeated the one button taped down cheat
12:02 PM Rab: There's a prominent optical fence that seems useless, I guess it's to keep the operator from sticking their head in.
12:02 PM renesis: they have buttons wired physically in series on a lot of machines
12:03 PM renesis: rab: or some second operator
12:03 PM renesis: but i wired both buttons to the controller directly, and the cycle wont reset unless both buttons go up after going down
12:04 PM Rab: renesis, crafty.
12:05 PM renesis: crafty people on both sides
12:06 PM renesis: i dont blame the ops tho, sometimes their targets dont make sense so theyre always figuring out ways to go faster
02:06 PM CaptHindsight: Are machine manufacturers making the setup process for machines easier for less knowledgeable people?
02:07 PM CaptHindsight: Are they becoming more like a toaster oven where you just set it at 250F for 20 minutes and you come back when it is done?
02:08 PM CaptHindsight: Do you just enter the material type thickness and size and the machine figures out the rest? Tool choice, feeds and speeds being the rest.
02:15 PM jymmmm: sounds good to me
02:22 PM {HD}: anyone have a shreadder they use for recycling stuff? I want a small shredder fitted to like a 55gal drum to throw steel scrap into.
02:26 PM CaptHindsight: most of my steel scrap is in chip form
02:26 PM CaptHindsight: larger stuff gets placed outside for scavengers to pickup
02:28 PM CaptHindsight: things like 55gal metal drums get rinsed and taken to the salvage yard
02:28 PM CaptHindsight: we have to clean them and have an opening large enough for someone to examine the inside for cleanliness
02:30 PM Tom_L: you don't sort and sell?
02:34 PM CaptHindsight: don't have enough hips to care
02:35 PM CaptHindsight: and the bigger scrap feeds a poor scrapers family
02:35 PM CaptHindsight: hips/chips
02:35 PM CaptHindsight: I don't have big hips either
02:36 PM {HD}: Is scrapping even profitable anymore?
02:36 PM Tom_L: yeah chips aren't worth as much
02:36 PM Tom_L: {HD}, depends on the volume
02:37 PM Tom_L: the shop my kids work at sort and save but they probably have 50 cncs
02:37 PM CaptHindsight: https://live.staticflickr.com/4131/4965035939_90f42d9e29_z.jpg
02:38 PM CaptHindsight: I left a bunch of drums outside once marker scrap
02:38 PM CaptHindsight: they took them once
02:38 PM Tom_L: sanford and son
02:38 PM CaptHindsight: yeah
02:39 PM CaptHindsight: probably though they found a gold mine just to discover that the metal recyclers don't take dirty drums
02:40 PM CaptHindsight: be back later when I can spell again
02:50 PM robotustra: test
03:08 PM Deejay: gn8
04:13 PM roycroft: cutting dovetails in really hard wood that is 2-3x as thick as usual is not 2-3x as difficult to do - it's more like 10-15x as difficult
04:13 PM roycroft: add that to my never having cut hounds tooth dovatails before, and things are going very very slowly
04:13 PM roycroft: but i have not screwed up yet!
04:14 PM JT-Shop: nice
04:14 PM roycroft: and when i finally get to the pins, that is in walnut, so it will be way easier to work with
04:14 PM roycroft: ash is a real bitch to hand tool
04:14 PM roycroft: it's super super hard, and it's all splintery and splitty
04:15 PM roycroft: read the grain wrong or tap a chisel a wee bit too hard or crooked and you have a giant splinter
04:15 PM JT-Shop: ouch
04:16 PM roycroft: two weeks ago today i did something i should have done years ago though
04:16 PM roycroft: i have a small cabinet next to the utility sink in my shop
04:16 PM roycroft: it normally has a dish rack on it and i use it to drain/dry brewing gear
04:16 PM roycroft: and i usually just leave the gear there, covered with a towel, because i'm too lazy to put it all away
04:17 PM roycroft: but i cleared all of that stuff off, and turned the countertop into a dedicated sharpening station
04:17 PM roycroft: so i can run over every few minutes and lightly hone/lap my tools, before they get dull
04:17 PM roycroft: i do not know why i did not think of doing this years ago
04:19 PM roycroft: i've been making temporary spaces for sharpening, and it was such a pain to pull the diamond/ceramic/leather plates out, set them up on a waterproof mat, and clean the area all up after i avoided sharpening in the middle of a work session
04:19 PM roycroft: i'd just sharpen at the beginning and work until the tools got too dull
04:20 PM roycroft: now i sharpen like every 15 minutes, and it only takes a few seconds
04:21 PM roycroft: anyway, this is the home stretch
04:21 PM roycroft: once these dovetails are done, i can do the final assembly of the bench top, and then my bench will be fully functional
04:22 PM roycroft: i'm actually pretty pleased - it's not the 15th yet, my self-imposed deadline - and by the 15th i should be very close to completion
04:22 PM roycroft: i'm at 213.5 hours right now, right in the middle of my 200-250 hour estimate
04:23 PM roycroft: given the slowdown both in pace and in time able to be spent due to the smoke this past week, i think i'm doing well
04:55 PM zipper is now known as Guest57497
04:57 PM JT-Shop: yea probing routine is working now https://ibb.co/SVCx5FJ
04:57 PM Tom_L: cool
04:58 PM Tom_L: inputs to a file?
04:58 PM JT-Shop: yea
04:58 PM Tom_L: crazy decimal places :)
04:58 PM JT-Shop: https://dpaste.com/8SCZSB24T
04:59 PM Tom_L: nice one
04:59 PM JT-Shop: yea for a plastic tubby lol
04:59 PM Tom_L: will it probe z as it goes?
04:59 PM JT-Shop: no, just XY
05:00 PM JT-Shop: it will probe odd shapes to some degree
05:00 PM Tom_L: you could pick up the z level as you go
05:00 PM Tom_L: do layers
05:00 PM JT-Shop: https://dpaste.com/7YBQ6ZDB7
05:02 PM Tom_L: nice
05:03 PM Tom_L: spent the last couple hours redoing a couple docs i lost the files for
05:03 PM Tom_L: at least i had a printout
05:04 PM JT-Shop: that can be a pita
05:10 PM jymmmm: Tom_L: dot matrix printout?
05:11 PM Tom_L: jymmmm, fanfold
05:11 PM jymmmm: Tom_L: In that case.... https://cloud.google.com/functions/docs/tutorials/ocr
05:12 PM Tom_L: i considered that but didn't wanna involve google
05:12 PM jymmmm: gotcha
05:12 PM Tom_L: they're nosey enough as it is
05:13 PM jymmmm: Tom_L: Google Inc, the commercial division of the NSA
05:21 PM CaptHindsight: scanner software used to come with OCR
05:22 PM CaptHindsight: a few open source OCR apps still out there that run locally
05:22 PM Tom_L: yeah i thought i might still have some but don't
05:24 PM Tom_L: it's nearly done now anyway
05:34 PM roycroft: hmm
05:34 PM roycroft: the smoke advisory was until noon tomorrow
05:34 PM roycroft: it's been revised to end at 11pm tonight
05:35 PM roycroft: it's still really smoky, and the aqi is currently 445 here, but that the advisory expiry time has been rolled back is encouraging
05:42 PM CaptHindsight: https://fire.airnow.gov/
05:44 PM XXCoder: low 200 here now
05:44 PM CaptHindsight: looks like we get winds here from the fires that are measurable
05:45 PM CaptHindsight: 2000 miles away
05:46 PM CaptHindsight: it's rare a that a forest fire has a noticeable effect around here
05:48 PM _unreal_: Cutting my first part for my daughters cnc machine
05:48 PM _unreal_: sigh.. this is going to take a bit of time
05:49 PM Tom_L: i thought it was nearly done
05:50 PM t4nk_freenode: first part _unreal_ ???
05:50 PM t4nk_freenode: you've been 'working' on this project... for over a year or so ;)
05:51 PM t4nk_freenode: btw my drill press is about done!
05:51 PM _unreal_: final parts for her Z
05:51 PM _unreal_: pen holder, "" spindle mount "" and laser mount
05:51 PM _unreal_: but i'm only going to set her up with a pen holder
05:53 PM jymmmm: YAY I was able to order my flashlight finally!!!
05:53 PM XXCoder: jymmmm: what flashlight?
05:54 PM _unreal_: flash light?
05:55 PM jymmmm: XXCoder: The same flashlight I've had for 5 years, just a backup in case I lost or broke the one I have... https://www.fasttech.com/p/1826602
05:55 PM XXCoder: dag thats wright kol
05:56 PM jymmmm: lol
05:57 PM jymmmm: It's been a damn good flashlight, bright, compact, and dual group
05:57 PM _unreal_: t4nk_freenode, pictures?
05:57 PM t4nk_freenode: yeah, I'll snap some in a bit
06:07 PM _unreal_: t4nk_freenode, https://drive.google.com/file/d/1rFEx3XtYgrmPli6b3nXNBJTHIRIF4vIo/view?usp=sharing
06:08 PM _unreal_: t4nk_freenode, ?
06:11 PM t4nk_freenode: looks like Lego ;)
06:13 PM jymmmm: CaptHindsight: Forget the smoke, I wanna see the satellite fires
06:15 PM jymmmm: CaptHindsight: (seriously, that's the kind of info we are not getting if we need to evacuate)
06:19 PM Tom_L: https://www.fire.ca.gov/incidents/
06:19 PM Tom_L: that?

06:33 PM CaptHindsight: real time fire sat data and map overlays
06:34 PM jymmmm: CaptHindsight: THANK YOU VERY MUCH!!!
06:34 PM jymmmm: Just need to find the time
06:34 PM jymmmm: like how old the data is, how often it's updated
06:34 PM CaptHindsight: they show the sat time overpasses
06:35 PM CaptHindsight: click Orbit Tracks and Overpass Times
06:37 PM CaptHindsight: jymmmm: looks like you get ~8 passes a day, 2 directly over you
06:38 PM CaptHindsight: 10:15 and 21:30 werethe last passes
06:38 PM jymmmm: CaptHindsight: so the data can be 24 hours old? Not like update every 15 minutes?
06:38 PM jymmmm: oh, so every 3 hours?
06:41 PM jymmmm: CaptHindsight: Times are in UTC? or "local" time?
06:41 PM CaptHindsight: 4 satellites in polar orbits
06:42 PM t4nk_freenode: _unreal_, https://postimg.cc/gallery/9DtzC0D
06:42 PM CaptHindsight: each make an orbit every 12 hours bu the looks of it
06:42 PM CaptHindsight: yeah was checking on the time they use
06:43 PM CaptHindsight: looks like NOAA-20 just went by minutes ago over you
06:44 PM CaptHindsight: right now it's ~20 mile north of Chico CA
06:44 PM CaptHindsight: just learning how to read the site
06:46 PM _unreal_: t4nk_freenode, I was expecting something 3d printed not purchased parts
06:46 PM jymmmm: CaptHindsight: where are you seeing te 20 miles north of?
06:46 PM t4nk_freenode: ? purchased parts?
06:47 PM t4nk_freenode: there's bolts, and threaded rod
06:47 PM t4nk_freenode: this is exactly what I got the printer for... to help me construct things
06:47 PM CaptHindsight: jymmmm: NOAA-20 satellite
06:48 PM t4nk_freenode: what good would a drill press be if it were all 3d printed?
06:48 PM CaptHindsight: a miracle
06:49 PM jymmmm: CaptHindsight: I see day and night for NOAA-20
06:49 PM t4nk_freenode: lol
06:50 PM jymmmm: CaptHindsight: screenshot maybe?
06:54 PM Tom_L: jymmmm, the menu on the right
06:54 PM Tom_L: the "I" on the satelite... click it
06:55 PM jymmmm: Tom_L: I see a day and a night
06:55 PM _unreal_: t4nk_freenode, if you can get into milling aluminum. it opens a whole new world of things to do
06:55 PM _unreal_: and build
06:56 PM _unreal_: IF/WHEN/ONCE you hve a working cnc mill
06:57 PM jymmmm: CaptHindsight: orbutal times are in UTC
06:57 PM * Tom_L gives jymmmm the satelite joystick
06:58 PM jymmmm: Tom_L: a screen shot would be better
06:58 PM jymmmm: brb

06:59 PM t4nk_freenode: I had never seen that picture before
07:00 PM _unreal_: I just took it
07:00 PM _unreal_: them
07:00 PM t4nk_freenode: lol, that's a real surprise ;)
07:00 PM _unreal_: othe white one is the panel for my daughters cnc machine main controller box
07:01 PM _unreal_: what is a surprise?
07:07 PM Thorhian: This is my machine so far. I have the X/Y axis running. Hopefully I'll have the Z motor mount done tomorrow.
07:07 PM Thorhian: https://imgur.com/a/NQiVhwt
07:08 PM _unreal_: Thorhian, make sure you have a good cover over your slides and balls crews
07:08 PM _unreal_: you'll likely want a rubber cover that rolls up at the ends
07:10 PM Thorhian: I have already bought some neoprene rubber for that purpose _unreal_ ;)
07:10 PM Thorhian: First chips hopefully will happen this week.
07:14 PM _unreal_: GOOD LORD thats a dull drill bit
07:14 PM _unreal_: EEEEEEEEEEEEEEE
07:15 PM Thorhian: ?
07:15 PM _unreal_: I'm doing my pecking cycle
07:15 PM _unreal_: all my 1/8th bits are f'ed
07:16 PM _unreal_: need to get more just have not wated to go to the store
07:16 PM Thorhian: Time to sharpen them lol
07:18 PM _unreal_: eeeeeeeeeeee
07:18 PM _unreal_: and I have ear plugs in too... my god
07:19 PM jymmmm: back
07:21 PM _unreal_: t4nk_freenode, notice the spindle RPM display on the left hand side of one of those photos I posted
07:26 PM t4nk_freenode: yeah
07:26 PM _unreal_: OH THANK GOD thats over
07:26 PM _unreal_: switching bits going back to milling
07:35 PM _unreal_: Thorhian, how are you planning on setting up your cover?
07:35 PM _unreal_: just draping? or is it going to be long enough that it requires the ends to be furled?
07:38 PM _unreal_: t4nk_freenode, uploading some more photos
07:39 PM _unreal_: https://drive.google.com/file/d/1D-0Kw51HgCqjT-5U4aN6qLpiST3BZx36/view?usp=sharing https://drive.google.com/file/d/1D36TAAbS0Wm4iubMwxe88_YHzj4yk9cN/view?usp=sharing
07:39 PM _unreal_: t4nk_freenode, like I said when you get to the point you can start milling aluminum it opens a LOT of doors
07:40 PM _unreal_: you guys can clearly see the drilled holes are a bit :sss CHEWY
07:40 PM _unreal_: god what a racket that was
07:40 PM _unreal_: EEEEEEE
07:40 PM _unreal_: you can see a nice chip load
07:40 PM _unreal_: 1/8th bit so the chips are small
07:41 PM _unreal_: I likely should speed the feed rate up a bit but the bit deflects a bit so.. ehh
07:41 PM _unreal_: wish my vacuum was stronger
07:42 PM _unreal_: just not enough suck to really clean the chips so I have to clean out the deep areas if I'm making a pass that is only a blade thick :(
07:44 PM _unreal_: ?
07:44 PM _unreal_: I've used upto a 1/4" end mill on my new spindle and BOY it was no slouch cutting aluminum :)
07:45 PM _unreal_: was VERY pleased with the results of that project
07:49 PM _unreal_: now I' to a point I have to clean it after every damn pass
07:56 PM _unreal_: hum quiet
08:22 PM _unreal_: yay my aluminum part is almost done
08:25 PM _unreal_: t4nk_freenode, a min left till my part is done and I'll clean it up
08:25 PM _unreal_: post a photo
08:25 PM _unreal_: :)
08:25 PM _unreal_: you'll be designing and printing parts to build a cnc machine in no time LOL
08:28 PM _unreal_: you know you have your feeds/speeds good when your metal part that was cut dry is just slightly worm to the touch
08:28 PM _unreal_: :)
09:11 PM t4nk_freenode: I'm not happy with the plastic rack... I slapped it on because I thought it would be nice
09:11 PM t4nk_freenode: ok, it is, lol.. but I didn't use a decent infill.. so I'm afraid I'll break it if I use too much force
09:14 PM t4nk_freenode: maybe I'll just fit a threaded rod, I wanna fit my normal drilling machine on there too
09:35 PM XXCoder: damn
09:35 PM XXCoder: went outside for few minutes to move stuff
09:35 PM XXCoder: bad air is bad
09:35 PM roycroft: it is
09:35 PM XXCoder: glad i cant smell it, my bro suffered lol
09:35 PM XXCoder: i can feel bad air though its not great
09:36 PM roycroft: i'll be glad when it clears up
09:38 PM XXCoder: indeed
09:38 PM roycroft: the holiday fire (the one just to the east of here) continues to grow, but with the westerly winds it's moving back towards the mountains
09:39 PM roycroft: one of the evacuation zones has been oked for folks to go home again
09:39 PM roycroft: but to remain ready to leave again
09:39 PM roycroft: and that's the evacuation zone closest to where i live
09:43 PM roycroft: the dense smoke advisory is still set to expire at 11pm tonight
09:44 PM roycroft: i'll be surprised if it clears up much by then
09:44 PM roycroft: the smoke is still really thick here
09:45 PM XXCoder: prediction says tomorrow will be 150s then down from there
09:45 PM roycroft: and the wind is only 10km/h, and slowing down
09:45 PM roycroft: so unless we're on the very very edge of the smoke it's oint going to be much better by 11
09:46 PM roycroft: the station near my house indicates an aqi of 713.4 at the moment
09:59 PM jymmmm: XXCoder: HEY, I have an idea.... why not make an air filter???
09:59 PM XXCoder: :P
10:00 PM Tom_L: must be approved though
10:00 PM jymmmm: must be ghetto faboulus
10:00 PM roycroft: where to get the parts?
10:01 PM Tom_L: 2x 20 x 20 quality air filters
10:01 PM roycroft: i was at a home depot store yesterday, and there were zero filters of any kind to be had
10:01 PM Tom_L: 1x cardboard box
10:01 PM roycroft: someone asked about them, and the store clerk said that they got a huge shipment in early that morning and they were gone within minutes
10:02 PM Tom_L: do you have a locke supply there?
10:02 PM jymmmm: Could use old fabric
10:02 PM Tom_L: hvac supply
10:02 PM roycroft: furnace filters are now like dust masks were in march
10:02 PM Tom_L: i get em by the box
10:02 PM Tom_L: i got a whole box full
10:03 PM roycroft: you would not be able to get a box full on the west coast right now
10:06 PM roycroft: and the thing is, one would need a hepa filter to clean the air of the harmful particulates
10:06 PM roycroft: they're really small
10:06 PM roycroft: i've been running the dust filter (non-hepa) in my garage shop, as well as the a/c unit
10:07 PM roycroft: and they help with some of the smell and irritants, but i know that the air is still hazardous
10:07 PM Tom_L: https://www.acehardware.com/departments/heating-and-cooling/air-quality/air-filters?facetValueFilter=tenant~A04648%3a10-merv%2ctenant~A04648%3a8-merv&query=undefined&categoryId=986
10:08 PM jymmmm: You can make a water based air filter too
10:08 PM jymmmm: aka party bong
10:08 PM Tom_L: YEAH!!
10:10 PM XXCoder: Tom_L: dang! i was lucky to buy em right before smoke get bad
10:10 PM XXCoder: its keeping this house nice and clean aur
10:11 PM Tom_L: i keep several on hand all the time
10:11 PM XXCoder: i have third sheet I might cut into shape and use for my ac intake filtering
10:12 PM XXCoder: though I would sequeeze it a bit for more surface area
10:18 PM roycroft: 443.1 right now
10:18 PM roycroft: so it really dropped in a short period of time
10:18 PM XXCoder: wow
10:19 PM XXCoder: still over twice here lol
10:19 PM XXCoder: 208 here
10:19 PM roycroft: it was down to 128 yesterday morning for a bit
10:19 PM roycroft: but with the kind of drop we just had, perhaps we are on the very edge of the smoke
10:20 PM roycroft: and perhaps by 11 we'll actually have some nice, fresh ocean air
10:20 PM roycroft: that would be lovely
10:21 PM roycroft: and it's supposed to rain later on this week, which would start washing the ash away
10:21 PM roycroft: it might stop looking like the moon
10:21 PM XXCoder: 58f here rain thursday
10:22 PM _unreal_: t4nk_freenode, infil can be a tricky thing.
10:22 PM XXCoder: 293 now wow!
10:22 PM _unreal_: you also want to look at melting the surface
10:22 PM XXCoder: increased a kiot
10:22 PM _unreal_: XXCoder, ?
10:23 PM _unreal_: ?
10:23 PM _unreal_: no idea what your talking about
10:23 PM roycroft: air quality index
10:23 PM _unreal_: ? ok.....
10:23 PM _unreal_: I'm in south florida
10:23 PM roycroft: we're not
10:23 PM _unreal_: :p
10:24 PM roycroft: when you have hurricanes we discuss them here
10:24 PM _unreal_: HEH
10:50 PM CaptHindsight: only they keep missing him
10:51 PM CaptHindsight: how does one become an adult and still think this way?
10:53 PM XXCoder: you guys talking with unreal?
10:53 PM Tom_L: no, he's not real
10:55 PM CaptHindsight: fodder for situational comedy
10:56 PM _unreal_: i'M UNREAL
10:56 PM _unreal_: lol
10:57 PM _unreal_: well I'm happy with the finish quality of the first major part I made
10:57 PM CaptHindsight: negative attention theater
10:57 PM _unreal_: tomorrow after work I'll setup my xy and run the part on the reverse side to do the half round deletion
10:58 PM _unreal_: rather then MAKING/MILLING a jig to do the other side
10:58 PM _unreal_: no point
10:58 PM _unreal_: I can do the rest on my drill press for the first part
10:58 PM _unreal_: I'm torn between doing a few of the other parts in aluminum or doing them in starboard
10:58 PM _unreal_: hum
10:59 PM CaptHindsight: XXCoder: are you just downwind or are your fires near?
10:59 PM XXCoder: nowhere near fires
10:59 PM XXCoder: quirk of wind patterns
11:00 PM _unreal_: I'm just enjoying a SEA breaze here :)
11:00 PM _unreal_: sigh midnight
11:00 PM _unreal_: guess I should head to bed
11:00 PM _unreal_: I do have to work tomorrow :(
11:00 PM XXCoder: one of reasons we almost never get snow beyond light snow that dont surive contact with ground heh

11:01 PM _unreal_: WHAT SEA BREEZE?
11:02 PM _unreal_: That state... is on fiyaaaaaaaaaa. That state is on fiyaaaayayaaaaaa...
11:04 PM _unreal_: FUNNY. how CALI could clear about 2k acers of forest in patches and thinning via logging. revive an industry etc.. BUT NO.... FUCK NO.... they would rather blame global worming and let tens of thousands of acers burn to the ground.
11:04 PM _unreal_: 2k=20k
11:07 PM _unreal_: t4nk_freenode, you have a few options. as far as your printed parts. one you can use an IRON and melt the surface. BUT that will only gain you so much. the other and BETTER follow up option. is to get cheap EPOXY AND A chicken injection syringe and long tiny drill bits depending on the parts. drill a hole and inject your parts with epoxy
11:07 PM _unreal_: when it cures you have a far more rigid part.
11:08 PM _unreal_: an other option is to stop short of the final layer and fill the infill with cheap epoxy resin. becuarful its not one that will thermal on its self in mass.
