01:19 AM Deejay: moin
05:01 AM JT-Cave: morning
05:01 AM XXCoder: hey
05:02 AM XXCoder: you linked me that probe thing that uses rods for contacts right?
05:02 AM XXCoder: also adjustable for centering
05:23 AM Loetmichel: *aahhhh* Half a day of dismantling and reassembling a new modified laserprinter. Works when the filter board is just plugged in "flying", throws a ton of different errors if its in its brass case. Finally found the problem: one of the EMI gaskets between the brass enclose and the filter PCB was to close to an FFC connector and touched the FFC contacts... but only when compressed enough to
05:23 AM Loetmichel: widen to that point. HUUUARGH!
05:24 AM Loetmichel: I HATE it when the errors hide that way!
05:25 AM XXCoder: lol
05:25 AM XXCoder: programming error that comes up once per 1000 uses is extremnely hard to find and fix too
05:26 AM Loetmichel: yep. What threw me for a loop was that it was a different error every time i reassembled it
05:26 AM XXCoder: ow
05:26 AM Loetmichel: depending on which signal was shorted to ground by that metallized fabric gasket
05:28 AM XXCoder: yeah
05:29 AM XXCoder: JT-Cave: i cant find that dratted probe. was it you who linked it to me? it used 6 precision rods rather than balls for 3d probe
05:40 AM JT-Cave: not me
05:40 AM XXCoder: drat
05:47 AM Tom_L: morning
05:47 AM XXCoder: yo
05:47 AM XXCoder: see above, you remember that project?
05:47 AM Tom_L: i made one
05:48 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/emc/probe_index.php
05:48 AM XXCoder: nice!
05:49 AM XXCoder: unfortunately not one im talking about. oh well
05:49 AM Tom_L: http://fadedbits.com/2011/02/touchprobe/
05:49 AM XXCoder: one im talking about uses 8 precision rods
05:49 AM Tom_L: http://www.vinland.com/Touch-Probe.html
05:49 AM Tom_L: no i didn't link that one
05:49 AM XXCoder: it was amazing because its far easier to source
05:50 AM XXCoder: and much more adjustable
08:10 AM gregcnc: https://www.precisionballs.com/images/tdsk5.gif
08:20 AM gregcnc: I vaguely remember something like this https://imgur.com/a/t3hz5AA
10:46 AM Loetmichel: maaan, deep cuts healing... $me has the ITCH on the left hand. its driving me crazy.
10:46 AM gregcnc: loetmichel consider a kevlar bodysuit
10:48 AM Loetmichel: gregcnc: wasnt that bad last week. Just slipped with the sharpened putty knife while removing 3d prints from the printbed. but now its healing and is ITCHING like crazy. -> http://www.cyrom.org/palbum/main.php?g2_itemId=17987&g2_imageViewsIndex=1
10:49 AM TekniQue: has anyone here used one of those chinese USB pendants with LinuxCNC?
10:50 AM gregcnc: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_XHC-HB04_Wireless_MPG_Pendant
10:54 AM jymmmm: Morning
10:55 AM jymmmm: They have some really nice people at precionballs.com
10:56 AM jymmmm: If you are local, they'll let you hand fill ball screws
10:57 AM TekniQue: local to where? Zhenzhen?
10:57 AM jymmmm: Los Angeleos
11:23 AM SpeedEvil is now known as Guest5643
11:38 AM Loetmichel: $me playing air guitar AND air drumset ... Ram Jam Black Betty is on the radio ;)
12:35 PM Tom_L: happy friday
12:41 PM gregcnc: is that what day it is?
01:13 PM roycroft: it is friday, and that fact pleases me to no end
01:48 PM * JT-Shop saw a drop of rain after lunch and took the rest of the day off
03:40 PM jymmmm: It's LOCKDOWN Friday... What I got on my phone today... https://i.imgur.com/fMDup6k.png
03:40 PM ve7it: jymmmm, !
03:41 PM jymmmm: Hi ve7it, how goes?
03:42 PM ve7it: not bad... just came back from a littlw walk... still huffing and puffing
03:42 PM jymmmm: up hil.... both ways?
03:42 PM ve7it: nice notice on your phone!
03:44 PM ve7it: I love how the news is promoting the vacine... most of us wont see it for at least a year... probably good... I couldnt even get a flu shot this year.. all booked up
03:47 PM Tom_L: jymmmm, doin ok?
03:48 PM jymmmm: Tom not bad, the cells I got are discharging just sitting on the bench, so yeah, need to find new ones.
03:50 PM Tom_L: no charger?
04:01 PM jdh__: I could have gotten a flu shot at 15 different places on my drive home from work.
04:54 PM JT-Cave: what good does a flu shot do?
04:54 PM Tom_L: gives you the flu?
04:54 PM JT-Cave: yeah don't need that lol
04:55 PM * JT-Cave has never gotten a flu shot
04:56 PM Tom_L: me either
04:56 PM Tom_L: can't recall ever getting the flu either
04:56 PM Tom_L: at least not bad enough to put me down
04:57 PM Tom_L: is 2.8.x upgradeable on wheezy?
04:57 PM Tom_L: from 2.7.x
04:57 PM Tom_L: i thought about putting it on the mill this weekend
05:05 PM JT-Cave: 2.8 should work on wheezy... what version of debian is that?
05:05 PM djdelorie: if you've never gotten the flu, thank all the people around you who did get the shot ;-)
05:05 PM JT-Cave: thank the cat and the birds?
05:05 PM djdelorie: and the bats, don't forget the bats.
05:06 PM JT-Cave: I need to build a target retrieval system for 10 lane indoor shooting range
05:06 PM JT-Cave: bats don't hangout with me... I see some from time to time
05:08 PM JT-Cave: I wonder where my stepper winder example is...
05:09 PM JT-Cave: crap now firefox is looking for matches for my local html page instead of loading it wtf
05:11 PM JT-Cave: I wonder what kind of motor I can find to use for the target retriever??? pretty small would work it's just a piece of paper
05:19 PM Tom_L: sounds like a fun challenge
05:20 PM JT-Cave: should be pretty straight forward I "think"
05:20 PM Tom_L: heck my sherline spindle motor might do that :)
05:20 PM Tom_L: cable driven?
05:20 PM JT-Cave: I'm thinking maybe a 60rpm 12vdc gear motor
05:21 PM JT-Cave: that's what I'm thinking a paracord driven system
05:21 PM Tom_L: you building the target holder and the whole thing?
05:21 PM JT-Cave: going to talk to the guy Monday
05:21 PM Tom_L: may want steel cable in case it gets hit
05:22 PM JT-Cave: depends on how high up it can be, steel would be heavy and take more power
05:22 PM Tom_L: true
05:25 PM JT-Cave: light rain here, temp goes back under Sunday night
05:27 PM JT-Cave: went to put the anti-kickback shaft with 29 kickback things and 30 spacers but something is wrong the shaft does not line up on the far side so a bit of testing tomorrow to see which way the bent shaft goes back in...
05:39 PM Tom_L: been cloudy all day but no precip
05:39 PM -!- #linuxcnc mode set to +v by ChanServ
05:44 PM andypugh: Well, no more work for me this year.
05:44 PM JT-Cave: is that good or bad?
05:44 PM andypugh: (I actually had enough holiday to stop last Friday, but I can carry some over, and hopefully we can actually go places next year.
05:46 PM XXCoder: hey andy
05:46 PM andypugh: These sold well (I said I would make them for the price of a beer) https://www.ebay.co.uk/itm/Holbrook-Tailstock-Dibber/114570478643 But can you guess what they are for?
05:47 PM pfred1: clearly a trepanning set
05:47 PM XXCoder: screwdrivers ;)
05:47 PM pfred1: for those without enough holes in their heads
05:48 PM andypugh: A clue: They fit into a hole in the top of the tailstock of a Holbrook lathe.
05:51 PM Tom_L: made on a Holbrook lathe?
05:52 PM andypugh: Indeed: https://youtu.be/KrkwFbDMcsY
05:52 PM JT-Cave: no idea what a dibbler would be used for on a lathe
05:53 PM JT-Cave: but you need to make more your out of stock on both sizes
05:53 PM jdh__ is now known as jdh]
05:53 PM andypugh: There is a reservoir in the tailstock for lubricant, the dibber sits in that as a cap, and the blade is for applying lubricant to your tailstock centre.
05:54 PM JT-Cave: interesting indeed
05:54 PM Tom_L: mighty fancy dip stick :)
05:54 PM andypugh: It is, as far as I know, a unique feature of Holbrook lathes.
05:54 PM JT-Cave: lol
05:55 PM JT-Cave: is the lube for a dead center?
05:55 PM JT-Cave: or even the centre
05:55 PM andypugh: Yes, most of the lathes date from a time when that it all that there were. Though there is on in my 1965 Minor too.
05:56 PM JT-Cave: I think that old Atlas I had included a dead centre
05:56 PM Tom_L: i think mine has one but i got a live center for it
05:57 PM JT-Cave: hmm I seem to recall a half dead center of sorts
05:59 PM andypugh: If you need a half-centre then it has to be a dead centre.
06:00 PM JT-Cave: yep
06:00 PM andypugh: But, wierdly, my dad once got (cheap) a live-centre that was ground into a half-centre. Never worked out if it was for a very specific part, or if someone really didn;t think it through and ruined a live centre before reealisiing their error.
06:02 PM JT-Cave: I guess if your doing a cam or something on a cnc lathe it "might" work
06:03 PM XXCoder: I hate special tools lol. I remember one tool that require this steps to be done: put 45 degree tool on toolholder. measure it. take tool in toolholder to grinder and grind tip off
06:04 PM JT-Cave: I think I see where someone screwed up the submakefile in 2.7 and lost the columns in the man pages but too tired to try and fix that today
06:06 PM JT-Cave: andypugh, I reworked the alignment example to make it work both for x axis and y axis... one was broken
06:14 PM andypugh: JT-Cave: Thanks. Whether anyone will find it is debatable, but it’s nice to be able to point forum and mailing list users at an example that they can run when they ask the question.
06:15 PM JavaBean: https://kvia.com/news/us-world/2020/12/11/after-51-years-the-zodiac-killers-cipher-has-been-solved-by-amateur-codebreakers/
06:17 PM pfred1: JavaBean yeah that cypher has been "solved" many times
06:17 PM pfred1: it's probably gibberish
06:17 PM JavaBean: still interesting
06:18 PM pfred1: after the first cypher got cracked he likely made up the second one just for laughs
06:19 PM pfred1: and made it unsolveable
06:23 PM andypugh: Maybe the same guys could try https://en.wikipedia.org/wiki/Voynich_manuscript
06:27 PM CaptHindsight: andypugh: happy time off work to you!
06:27 PM andypugh: I doubt that I will run out of projects to do.
06:28 PM andypugh: This will be the first christmas that I have ever spent at home by myself.
06:28 PM CaptHindsight: andypugh: how is the new RTAI behaving for you?
06:29 PM andypugh: I haven’t really looked at it since I put the debs out.
06:29 PM CaptHindsight: yes, lots of firsts this year
06:29 PM Tom_L: andypugh, your mum doesn't video chat?
06:29 PM andypugh: (other projects)
06:29 PM Tom_L: set her up with something...
06:29 PM andypugh: My mum will be spending the day with my sisters.
06:30 PM andypugh: (My dad will be isolated in the old folks home, so I don’t feel I have the right to sulk too much)
06:30 PM CaptHindsight: andypugh: i lost track, did you still get errors when you made the debs? load/unload or running the absolute value test etc
06:30 PM andypugh: Yes, with the debs the abs loop still crashes.
06:31 PM CaptHindsight: thanks
06:31 PM andypugh: I am not sure that the load/unload does. In that it crashed once, but possibly that was something else. I ran 150,000 cycles without a crash
06:33 PM CaptHindsight: happy Friday, bbl
06:52 PM XXCoder: regrinding carbide inserts https://youtu.be/UUVvgcvlbBs
07:01 PM andypugh: That was ironic
07:02 PM XXCoder: in what way?
09:24 PM veegee: I'm so excited
09:24 PM veegee: and I just can't hide it
09:25 PM veegee: I'm about to lose control (on a 23,000 lb forklift) and I think I like it
09:25 PM veegee: $2,500 deal of the century. Everything works
09:26 PM veegee: Also my custom made 1,000A full bridge motor controller works really nicely
09:26 PM XXCoder: youre truning shop into display collection of forklifts? ;)
09:26 PM veegee: Even etched the PCB myself via toner transfer and ferric chloride. I should get it made by an actual PCB manufacturer with solder mask and silk screen
09:27 PM veegee: XXCoder this one's for outside. I decided against making a ramp when I got this deal
09:27 PM XXCoder: :)
09:27 PM veegee: So I can load my car inside with the forklift now easily
09:27 PM veegee: My Jeep Wrangler Unlimited is < 5,000 lb so I don't need to even think about load centres and all that
09:28 PM veegee: The machine will easily put it on the roof of the building no problem
09:30 PM XXCoder: lol cool though
10:04 PM veegee: This god damn winter makes my skin dry
10:04 PM veegee: the one and only bad thing about Canada is the winter weather
10:05 PM veegee: I've tried everything, nothing works. Lotion doesn't last long enough
10:05 PM veegee: Any kind of oil like vaseline clogs the pores and causes acne
10:05 PM veegee: Alpha hydroxy acid works but it stings your whole face and makes it feel like it's on fire on already cracked and dry skin
10:06 PM veegee: So now I'm sitting here like a jackass putting tape on my face and peeling it off to get rid of the layer of dry skin
10:06 PM XXCoder: how about cocoa butter by company jasom
10:06 PM veegee: It should work, but the only problem is it doesn't last long
10:06 PM XXCoder: its been helpful on my dry skin, its far dryer here this year than usua;
10:07 PM veegee: and what's worse, my feet get sweatier for some reason
10:07 PM veegee: because of the dry weather, not the lotion
10:08 PM veegee: I got a prescription of retin-A that promotes shedding the outer skin layer. It makes the skin peel off like a snake shedding its skin
10:08 PM veegee: it reveals a super smooth moist fresh layer, but it's insanely sensitive
10:09 PM veegee: even mild lotion makes it burn like crazy
10:09 PM XXCoder: woulnt know if cocoa butter one would burn or not
10:09 PM veegee: It's not the cocoa butter, it's usually the _other_ things in it like glycerin
10:09 PM XXCoder: mayb look up what oil is good for skin and just directly pply that
10:10 PM veegee: Yeah oil will work but makes me break out
10:10 PM veegee: I was super acne prone as a kid. It naturally went away with age, but it'll come straight back if I clog the pores with oil
10:11 PM XXCoder: i hate trying to google stuff like that. natural bullshit results
10:11 PM veegee: damn, I remember the university days, had to use benzoyl peroxide and all sorts of stuff
10:11 PM veegee: worked really well though
10:12 PM XXCoder: maybe some very thin oil to soak in, but pores would clear out easily?
10:13 PM XXCoder: one im using is pretty light but not that light. ligher than fairly heavy oil typical in skin creams
10:13 PM veegee: Fell for that once, great way to dissolve all the natural skin oil and make it even more dry
10:13 PM veegee: Oh, thought you meant like kerosene
10:13 PM veegee: or brake cleaner
10:13 PM veegee: (just kidding, I'd never put brake cleaner on my face lol)
10:14 PM XXCoder: i stopped lotion for a bit because theres some skin damage that it keeps getting worse (while dry skin around it has improved)
10:14 PM XXCoder: so far skin isnt drying out agaib
10:14 PM veegee: Alpha hydroxy acid works the best so far
10:14 PM XXCoder: is that even a oil?
10:14 PM veegee: Not at all
10:15 PM veegee: it's a weak acid, like citric acid
10:15 PM veegee: it promotes shedding the outer layer of skin, growth of new skin and collagen
10:15 PM XXCoder: using this btw https://images-na.ssl-images-amazon.com/images/I/61Dj8lF5QzL._SY450_.jpg
10:16 PM veegee: But until your skin gets used to it, the roughness of your own fingerprint hurts while applying it
10:16 PM XXCoder: ouch
10:16 PM veegee: and it stings like you can imagine - acid on fresh skin
10:17 PM veegee: like it hurts way more than pouring alocohol or hydrogen peroxide on a wound
10:17 PM XXCoder: whys you doing that anyway
10:17 PM veegee: just because of the huge surface area
10:18 PM veegee: it's a standard process for restoring the elasticity and moisture of skin
10:18 PM veegee: I just have more sensitive skin than average
10:18 PM veegee: just on the face, fine everywhere else. Weird.
10:19 PM XXCoder: oh well
10:19 PM veegee: where's that damn heroin when I need it
10:23 PM XXCoder: dont know jej
