12:09 AM rue_shop3: want to move to canada yet?
12:12 AM Tom_L: it's getting ridiculous here
12:12 AM Tom_L: that incident already made it into wikipedia
12:12 AM rue_shop3: the authorities are doing it to 'make the country a better place'
12:12 AM rue_shop3: someone has a warped sense of better
12:12 AM Tom_L: i just hope they catch the gamers
12:13 AM Tom_L: i need to finish mounting it though
12:13 AM rue_shop3: cool
12:13 AM rue_shop3: is the drive gonna fit ok?
12:13 AM Tom_L: i only got about an hour to work on it tonight
12:14 AM Tom_L: should
12:14 AM Tom_L: i _am_ gonna extend that Z overhang though
12:14 AM Tom_L: probably another 2" or so
12:14 AM rue_shop3: (sorry, I have to distance myself from the insane real world)
12:14 AM Tom_L: so 6" instead of 4
12:14 AM rue_shop3: wow
12:14 AM Tom_L: did you see all the travel it has?
12:15 AM rue_shop3: no, it looks great
12:15 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/X_Axis_travel2.jpg
12:15 AM rue_shop3: I been working on the helping hands thing
12:15 AM Tom_L: with it all the way in, it doesn't quite reach the far edge of the table
12:16 AM rue_shop3: the range is larger than the table tho?
12:16 AM Tom_L: yeah
12:16 AM rue_shop3: ...
12:16 AM rue_shop3: tool changer on edge?
12:16 AM Tom_L: i just want to make sure the spindle can reach the edge of the table
12:16 AM Tom_L: when it's all the way in
12:17 AM Tom_L: i'm sure i won't use all the Y travel
12:17 AM Tom_L: but if i have an awkward part or something it will still fit
12:18 AM rue_shop3: remember the moce you extend that out, the more of the track play you get
12:18 AM Tom_L: i know
12:18 AM rue_shop3: c, is c close to r? seriously?
12:20 AM rue_shop3: still dont see any of those drarwrs with clean handles....
12:20 AM Tom_L: the bottom ones are
12:21 AM Tom_L: hah, i pull them out from the bottom
12:21 AM Tom_L: that's why
12:25 AM Tom_L: i'm gonna have to raise it up though, the drag chain won't bend tight enough to fit under the X table
12:27 AM Tom_L: i think i could have gotten away with smaller chain too
02:35 AM ferdna: ...
05:31 AM rue_shop3: helping hands are comming togethor, slowly as the 3d printer cant keep up
05:31 AM veverak: well
05:31 AM veverak: from bussiness view
05:31 AM veverak: the fact that I builded two 3D printers in my company has benefits
05:32 AM rue_shop3: builded -> built
05:32 AM veverak: ah, yeah
05:32 AM rue_shop3: past context
05:32 AM veverak: yeah, completely forgot
05:32 AM rue_shop3: is the other language russian?
05:32 AM rue_shop3: I feel I should know this by now
05:33 AM veverak: I want to leave the company, but stay for maintanenace of things I created
05:33 AM veverak: benefit? I can still play with 3D printers and nothing of the boring stuff around ;)
05:33 AM veverak: rue_shop3: mine other? no, czech language
05:33 AM rue_shop3: oh
05:34 AM rue_shop3: its 3:30am
05:34 AM rue_shop3: I should probably go to sleep
05:34 AM veverak: both are slavic languages though
10:34 AM To_Aru_Shiroi_Ne is now known as ToAruShiroiNeko
11:01 AM robotustra: <@rue_shop3> want to move to canada yet?
11:01 AM robotustra: do you think canadian police is less violint?
11:02 AM anonnumberanon: rue_shop3 you wanted me to freaking work on metal stuff? What you talking about? Look here: https://pasteboard.co/H0D9InE.jpg
11:03 AM * anonnumberanon is glad to have a real reason not to be productive
11:04 AM anonnumberanon: And its -8c
11:04 AM Tom_L: that's a pitiful excuse
11:04 AM anonnumberanon: -8
11:04 AM anonnumberanon: -8
11:04 AM anonnumberanon: -8
11:04 AM Tom_L: that's a pitiful excuse
11:04 AM Tom_L: that's a pitiful excuse
11:04 AM Tom_L: that's a pitiful excuse
11:05 AM Tom_L: unless you're deceased you should always be productive
11:05 AM robotustra: fuck stupid dumb police
11:05 AM robotustra: idiots
11:05 AM robotustra: fucking idiots
11:06 AM Tom_L: i think the gaming industry should hold some accountability too
11:06 AM robotustra: I think police should verify better
11:06 AM Tom_L: i'm not disagreeing with that
11:08 AM robotustra: this case shows how stupid system is
11:08 AM robotustra: somebody called - they went and killed somebody
11:08 AM robotustra: as stupid as that
11:08 AM robotustra: no verification, nothing
11:09 AM robotustra: it's called social engineering hack
11:09 AM Tom_L: one person arrested was in another state
11:10 AM robotustra: one more thing - if you play shooting games, do not use tweeter of any other social media
11:10 AM robotustra: do not use live chats
11:10 AM robotustra: and so on
11:12 AM anonnumberanon: Oh well ill still do stuff but inside. On the computer. I am trying to finalize my last push towards PWM driver. If dont work then ill either limit the resolution to 5 microseconds or move to arm.
11:13 AM anonnumberanon: Nah man i think the guy who got shot didnt act correctly. He must have made a small mistake.
11:14 AM anonnumberanon: You dont open your door to anyone shouting and carrying guns. You try to diffuse the situation
11:14 AM anonnumberanon: I would have called the cops and asked to speak with the negotiator.
11:16 AM robotustra: anonnumberanon, he got a bullet, do you think your life should depend on artificial situation where you should not do any mistakes?
11:16 AM robotustra: it's rediculous
11:16 AM anonnumberanon: No i dont but with the police state you have no choice
11:16 AM anonnumberanon: You must know about interacting with the police now more than ever
11:17 AM robotustra: https://imgur.com/B3GyCH0
11:17 AM anonnumberanon: This was a huge police fuckup though.
11:17 AM robotustra: may be because ppl should fuck the police's brain more often?
11:17 AM anonnumberanon: Was that swat or police who shot?
11:18 AM anonnumberanon: Swat usually dont happy trigger finger.
11:18 AM anonnumberanon: They have better trigger discipline and control.
11:19 AM anonnumberanon: Yeah i saw your starret last night all i could think was dont ever run with this thing in your hand...
11:19 AM robotustra: what?
11:20 AM robotustra: I'm just checking the table flatness
11:20 AM robotustra: it's withig +- 0.001"
11:20 AM robotustra: acceptable
11:24 AM anonnumberanon: Yeah this thing has 2 very sharp ends it looks quite dangerous
11:37 AM robotustra: which one?
11:37 AM robotustra: scrapers?
11:37 AM Tom_L: no, his new height gage
11:37 AM robotustra: they should be sharp to scrape metal
12:02 PM anonnumberanon: Robotustra im talking about ur new tool
01:08 PM rue_mohr: next tues is back to work
01:08 PM rue_mohr: hopefully I dont just go into shock

02:03 PM robotustra: that's the plan https://imgur.com/B6iN6vL
02:05 PM mrdata: oooh
02:08 PM anonnumberanon: How does that giant compass thingy even scrape?
02:27 PM robotustra: it's not a compass
02:27 PM robotustra: it's dial indicator
02:27 PM robotustra: I measure the deflection from flat surface
02:28 PM robotustra: and the niddle is needed to scrape a line horizontal to the surface plate
02:28 PM robotustra: at definite distance
02:44 PM anonnumberanon: Ah i see
02:46 PM Tom_L: ok, got a pile of cheap limit switches today
02:48 PM robotustra: good ones?

06:28 PM malcom2073: ferdna: https://www.hammfg.com/
06:28 PM malcom2073: Find a part number you want, and look it up on digikey/mouser/newark, they're not terribly expensive
06:28 PM rue_shop3: getting the guy around the corner to print you the other box is prolly cheaper and faster
06:29 PM malcom2073: True, but that's not commercial.
06:29 PM rue_shop3: are you gonna next tell me its not mass manufacturable?
06:29 PM ferdna: malcom2073, cool... thank you!
06:30 PM malcom2073: Nope, 3d printed parts are quite mass manufacturable
06:36 PM * Tom_L goes out to the shop

10:25 PM rue_mohr: whoa
10:25 PM rue_mohr: hey nice tap guide
10:25 PM Tom_L: home brew of course
10:25 PM Tom_L: i did one for M5 and M6
10:26 PM rue_mohr: someone ate your package
10:26 PM Tom_L: not much left in it now
10:26 PM rue_mohr: did you have to straighten those strips at all?
10:27 PM Tom_L: no they were the same thickness so i cut them to length and went to town
10:27 PM * rue_mohr squints
10:27 PM rue_mohr: steel?
10:27 PM Tom_L: i'm not concerned about the width on them

10:31 PM rue_mohr: I'm gonna be back at work wonder why the hell I didn't get any work done on __________________________
10:31 PM rue_mohr: and I wish I knew what it was
10:32 PM robotustra: Tom_L, you added some bars to be able to flip rails?
10:33 PM robotustra: and add some space for nut?
10:35 PM Tom_L: clearance for the screw yes
10:46 PM Tom_L: i'm quite impressed how 'tight' this thing is compared to the sherline
10:47 PM Tom_L: i haven't put any indicators on it yet but it's pretty darn solid
11:12 PM rue_shop3: ok, best case, tiny13 can to 19Khz pwm
11:13 PM Tom_L: spool feeder looks good
11:16 PM rue_shop3: :)
11:17 PM rue_shop3: the surprise was that the best part is it holding it up
11:17 PM Tom_L: what triggers the feeder?
11:28 PM Tom_L: rue_mohr, those tap guides is what you do with leftover lathe pieces that are too short for anything else
11:49 PM anonnumberanon: little C practice before bed, let's see how i can quickly remember how to sort structs with one of their elements as comparison function
11:54 PM anonnumberanon: anyone can also tell me the expression to do port manipulation on an avr?
11:55 PM anonnumberanon: forgot if it's like PORTB = 3; or something, to for instance turn bits 0 and 1 on.
