01:02 AM Deejay: moin
02:59 AM Centurion-Dan2 is now known as Centurion_Dan
03:41 AM Loetmichel: *PFUAAAH* Months old milling machine cooling fluid all over my body. Tried to clean out a clog in the spindle cooling circuit with compressed air. Result: the end of the hose hopped off the tank and liberally hosed me with cooling fluid. Sometimes i am a **bit** clumsy. :)
03:41 AM XXCoder: yummy
03:43 AM Loetmichel: XXCoder: not really. At least i used some car radiator concentrate to prevent bio growth. so it only stinks of glycol and additives, not rotten and foul. *keep trying to see the positive* :)
03:44 AM XXCoder: :)
04:16 AM miss0r: g'day
04:16 AM XXCoder: yo
04:20 AM Tom_L: morning
04:21 AM XXCoder: lo
06:01 AM JT-Cave: morning
06:25 AM miss0r: morning JT-Cave
06:25 AM miss0r: XXCoder: hey! I just completed the scrap proto of the filter consoles, wanna see?
06:28 AM miss0r: (you know, the imperfect one that all the code is tested and adjusted on)
06:29 AM miss0r: https://imgur.com/a/14L0tss
06:32 AM JT-Cave: is that the oil filter adapter thingy
06:55 AM miss0r: JT-Cave yes
07:33 AM * JT-Cave confirmed his suspension that microsoft had indeed created the worst piece of crap software in the universe with windblows 10
07:34 AM JT-Cave: suspicion even
07:34 AM htasta: hahahahahaha told ya so :D
07:34 AM JT-Cave: no you didn't
07:34 AM htasta: did you set the network to metered so it wont use up all your data?
07:35 AM htasta: to force it's dumbarse updates on you
07:35 AM JT-Cave: it's not connected to the lan
07:35 AM htasta: oh, yeah that works. until you want to download something but I guess you can just use some usb transfer
07:35 AM JT-Cave: yup
07:36 AM htasta: which laptop did you end up buying? I member you said you needed 17" you got one of thems?
07:37 AM JT-Cave: https://www.amazon.com/gp/product/B08HRHP6M2
07:37 AM JT-Cave: wanted 17"
07:38 AM htasta: hahahahha this description:
07:38 AM htasta: CPU Manufacturer Intel
07:38 AM htasta: AMD Quad-Core Ryzen 7 3700U
09:04 AM Loetmichel: *grrr*... why do the 99,5% Isopropyl alcohol bottles have to resemble soda bottles? Nearly made a grave mistake... :P
09:09 AM Loetmichel: <- is cleaning PCBs from flux residue. just reached blindly for the soda bottle and nearly drank, forgetting the IPA bottle next to it.
09:09 AM Loetmichel: ... definitive a "no smoking" job :)
09:12 AM roycroft: they do not look like soda bottles in the us
09:14 AM JT-Shop: the VMC is pretty much cleaned out so time to make chips
09:19 AM roycroft: no april showers for the forseeable future
09:20 AM roycroft: we just got out of a years-long drought, and were finally back to normal precitipation, and now the spigot has turned off completely
10:34 AM veegee: Hey guys
10:35 AM veegee: I found roycroft's secret side hustle
10:35 AM veegee: http://imgbox.com/Szash6fy
10:35 AM veegee: It's sleazy but I guess it pays the bills
11:15 AM roycroft: that must be in upstate new york, near buffalo
11:24 AM veegee: roycroft lol Toronto. I was just driving on a road I don't usually take
11:26 AM veegee: https://www.crescenttool.com/MagentoShare/media/documents/nicholson-guide-to-filing-2014.pdf useful information
11:33 AM roycroft: oh, toronto is not too far from buffalo
11:33 AM roycroft: a roycrofter could have escaped up to there
11:34 AM roycroft: perhaps a draft dodger in the '60s
01:01 PM * drdoc was a draft dodger
01:01 PM drdoc: for something like 83 days
01:25 PM roycroft: i was not
01:25 PM roycroft: i did not need to be
01:25 PM roycroft: the draft was abolished right before my 18th birthday
01:25 PM roycroft: and when selective service registration was reinstated a few years later, i was outside the window of those who needed to register
01:26 PM roycroft: so i've been legally not registered for selective service my entire life
01:26 PM drdoc: the draft was abolished right before my 18th birthday, but the law didn't go into effect until 3 months after
01:26 PM drdoc: so, technically, I *was* required to register
01:27 PM drdoc: I declined
01:28 PM drdoc: So, I'm trying to decide on the display for the linuxcnc machine
01:28 PM drdoc: 20" 1600x1200 or 15" 1024x768 touch screen?
01:29 PM roycroft: the former
01:29 PM roycroft: you are old
01:29 PM roycroft: the additional real estate will help
01:29 PM drdoc: lol, I are
01:30 PM roycroft: old eyes need all the help they can get
01:30 PM * roycroft speaks from experience
01:30 PM drdoc: hat's why I'm asking you.
01:53 PM roycroft: a touch screen is nice, but it doesn't help much if you can't read it
02:08 PM XXCoder: miss0r2: isnt that same photo you showed me bit ago? :)
02:09 PM miss0r2: theres more if you scroll down
02:09 PM miss0r2: I just put that in there for good measure ;)
02:10 PM * miss0r2 is beating my head in trying to make this CNC lathe do my bidding
02:10 PM XXCoder: ohh
02:11 PM XXCoder: nice
02:12 PM miss0r2: well.. I scrapped that part more than once during the "production"
02:13 PM miss0r2: It is absolutly unuseable :D but it looks the part atleast, if you do not inspect it too closely :D
02:13 PM miss0r2: But that is why I always make atleast one more than I need when doing small batches, so I can kick one around to do test setups on
02:14 PM XXCoder: indeed
02:14 PM XXCoder: i wonder if you could use one of holes on other side as bolt on for mounting strength
02:15 PM miss0r2: I have plently of mounting strength clamping the "ribbled" surface on the back. sorta the part that stiffens the angle
02:15 PM miss0r2: That is not my issue :D
02:16 PM miss0r2: One thing that realy fscked this one up was drilling one hole 10mm too deep, almost making it clean through the part
02:16 PM miss0r2: and other small alignment issues
02:16 PM XXCoder: doh
02:16 PM XXCoder: production you'd have special jaws for it
02:16 PM miss0r2: so one of the two 3/8BSF threads on the back only has half a thread on one side there hehe
02:16 PM XXCoder: one offs have hard life lol
02:16 PM miss0r2: Indeed. I've made 5 total
02:17 PM miss0r2: one was scrap.
02:17 PM miss0r2: :D
02:17 PM miss0r2: or it can still be used as an ornimental paper weight
02:17 PM XXCoder: just had interesting vise idea
02:17 PM XXCoder: you know how those special robot arm pick and place things have that rubber thing that can be soft or hard and firm?
02:18 PM XXCoder: use it for parts hold lol
02:18 PM XXCoder: doubt it'd be strong enough though lol
02:18 PM miss0r2: I doubt it will
02:18 PM miss0r2: :]
02:19 PM XXCoder: other probably useless interest - casing soft termosplastic, warm em up and cast it into part
02:19 PM XXCoder: so you have special jaws without expense of it
02:19 PM XXCoder: since you can melt em into blocks again
02:19 PM miss0r2: still doesn't sound too strong to me
02:19 PM miss0r2: I like to work the part hard :D
02:19 PM miss0r2: if I can get away with it anyway
02:19 PM XXCoder: probably bnot. maybe good only for small part
02:20 PM miss0r2: or rather small machining on large clamping surfaces
02:21 PM miss0r2: This lathe MUST be messing with me !
02:25 PM XXCoder: lol whats it do? owe you money? ;)
02:26 PM miss0r2: combination of me not knowing how many steps it takes to do one rev. of the z-axis with me not knowing anything about CNC lathes. Its a pretty steep learning curve atm
02:43 PM drdoc: something's terribly wrong here
02:44 PM CaptHindsight: is a 1/4-in-18 Npt hand tap so unusual now that hardware stores don't stock them?
02:44 PM drdoc: I'm doing some simple toolpaths is MeshCAM to try it out
02:44 PM drdoc: CaptHindsight: yes
02:44 PM drdoc: spot drilling 14 holes is a 15-minute op
02:45 PM drdoc: That ain't right
02:47 PM miss0r2: drdoc: Perhaps you forgot to uncheck "slow living"
02:47 PM drdoc: lol
02:48 PM drdoc: It *really* wants to drill the holes too, and I don't want to
02:48 PM drdoc: drill press is a lot faster after I "punch" centers, and I don't need the precision
02:48 PM miss0r2: tell its whos boss.. and when you are done with that, come tell my cnc lathe here that I am in charge.
02:49 PM roycroft: i find i can get precision to within <0.005" if i'm careful using a sensitive drill press
02:49 PM drdoc: first I need to find the bookmark to that online toolpath simulator
02:49 PM miss0r2: FSCK ME THIS IS DANGEROUS !
02:49 PM roycroft: that's good enough for most of the holes i drill
02:49 PM drdoc: roycroft: it's a $50 chinesium tabletop
02:50 PM drdoc: you're doing orders of magnitude better than me
02:50 PM drdoc: :-)
02:50 PM roycroft: there's more imprecision drilling to final size with a twist drill instead of using an undersize drill and a reamer than the imprecision of using a sensitive drill press instead of a milling machine
02:50 PM miss0r2: Using a touch screen here, trying to determin the settings for the ballscrews and have a TI mounted in X+ direction. Apparently the 'checktool' button is right below the incremental X+ button.. one slip of the finger and the thing came racing almost breaking my TI...
02:51 PM drdoc: roycroft: I won't argue that.
02:51 PM drdoc: wow
02:51 PM roycroft: now to be clear, i don't ususually get that kind of precision on a senstive drill press, because i don't need it
02:52 PM roycroft: but i can get it if i want to
02:52 PM drdoc: right
02:52 PM drdoc: that takes some time and care
02:52 PM roycroft: one of the more important lessons i learned early on in my machining classes was to machine to specifications, and no better
02:52 PM drdoc: I need half a mm for this part
02:53 PM drdoc: heh
02:53 PM drdoc: one of my foremen used to yell at me
02:53 PM miss0r2: roycroft: What I learned is that imprecisions stack.
02:53 PM miss0r2: Something like that atleast. and I am reminded daily :D
02:53 PM drdoc: "@!#$^$%#^&(*^R#$ DOC!! This ain't no Swiss Watch!!!
02:53 PM miss0r2: lol
02:54 PM roycroft: it's similar to one of the most important lessons one is taught in engineering classes, and a lesson that separates engineers from hacks - design to the required specifications, with an appriate margin of error, and no better
02:54 PM drdoc: miss0r2: if you cut to spec, stacked tolerance is the engineer's problem
02:54 PM miss0r2: drdoc: I've had that argument with a client or two over time. My repons is; "if I cannot get to do it properly, I will go away and you can find someone else to do it your way"
02:54 PM roycroft: miss0r2: that is correct, but that's part of the equation
02:55 PM drdoc: roycroft: at my last IT job we did enough custom fixtures to keep a solidworks person
02:55 PM roycroft: if you understand your process then you will be able to figure out how precise you need to be at each step of the process
02:55 PM bjorkintosh: drdoc, maybe it's indeed not a "@!#$^$%#^&(*^R#$ swiss watch" maybe it's a George Daniels!
02:55 PM miss0r2: I hate clients telling me to just slap a piece of duct tape on it, and it will be fine. I usualy tell them, theres no need to call me then
02:55 PM drdoc: one of her first projects was a mount plate for prototype motherboards
02:56 PM miss0r2: roycroft: THE EVERLASTING QUEST FOR PRECISION !
02:56 PM bjorkintosh: to how many decimal places?
02:56 PM drdoc: she sent the drawings off to the chinese contractor with default tolerance set
02:56 PM drdoc: +/-0.002"
02:56 PM miss0r2: on that node: I'm going to go look at an ID&OD cylindrical grinder later this week, with purchase in mind
02:57 PM miss0r2: drdoc: lol
02:57 PM roycroft: and they translated that to +/-0.002mm?
02:57 PM miss0r2: perhaps they misread " for '
02:57 PM drdoc: no, they cut plates to +/-0.002"
02:57 PM drdoc: +/-0.02 would have been fine
02:58 PM roycroft: yes, 0.002" is overboard for sure
02:58 PM roycroft: tolerance is important
02:58 PM drdoc: and damned expensive
02:58 PM miss0r2: hehe yeah
02:58 PM roycroft: overprecision costs money, and reduces profit
02:58 PM drdoc: it can also kill assembly
02:58 PM roycroft: reduced profit = reduced job security
02:59 PM drdoc: it certainly reduced Missy's
02:59 PM roycroft: it's an honest mistake for a newbie
02:59 PM roycroft: once
02:59 PM roycroft: after the first time it's a serious liability
02:59 PM drdoc: they didn't fire her, but she got thoroughly schooled
02:59 PM drdoc: yeah
02:59 PM roycroft: but did they specify the tolerance when they gave her the job?
03:00 PM roycroft: or was she expected to know that already?
03:00 PM roycroft: it needs to be in the work order
03:00 PM roycroft: every time
03:00 PM drdoc: I think they told her a hundredth
03:01 PM roycroft: oh, then it was totally on her
03:01 PM drdoc: yeah
03:01 PM roycroft: but still, she should be allowed to make that mistake once
03:01 PM roycroft: it cost the company money, but spending it one time is a training expense
03:01 PM drdoc: I've worked, in production, with tolerances from +/-0.375" to +/-0.0005
03:01 PM drdoc: roycroft: 100 plates
03:02 PM drdoc: 25-odd threaded holes
03:02 PM roycroft: so who was responsible for checking her drawings before they were sent off to the manufacturer?
03:02 PM roycroft: that's something that's always done, no matter how experienced the cad operator
03:03 PM drdoc: IHNI. I thought they went overboard, but I was just the IT Dude
03:03 PM XXCoder: drdoc: worse one i had was -0 +.0003"
03:03 PM roycroft: that's why title blocks in drawings have a "drawn by" and a "checked by" field, which must never be signed by the same person
03:03 PM drdoc: that's tight
03:04 PM roycroft: but at least, in the end, you got some really nice, precise mounting plates
03:04 PM drdoc: often the worst problem with overprecision isn't cost of the part, but assembly time.
03:04 PM drdoc: yes we did
03:04 PM roycroft: other mistakes could have resulted in both extra expense and useless parts
03:05 PM drdoc: oh yeah
03:05 PM drdoc: the guy she replaced had that set made with a riser in front of the USB ports
03:05 PM drdoc: the riser wasn't optional and neither were those ports
03:06 PM drdoc: that was the straw that kilt his camel
03:07 PM drdoc: he was everybody's worst nightmare - highly trained CAD guy who thought he was an engineer
03:07 PM drdoc: and no shop experience at all
03:08 PM roycroft: engineers should be required to spend 2 years in the field working the trades before they can get their pe license
03:08 PM drdoc: at least
03:08 PM roycroft: like a graduating med student needs to do an internship before getting a medical license
03:09 PM roycroft: towers are not made of ivory in the real world
03:09 PM drdoc: I did get an engineer under a truck with me at a welding job
03:10 PM drdoc: I was tacking 2 rods together to get 3-4 inches of overhead weld where he'd specced it, where a beveled weld from the top would have been fine
03:11 PM drdoc: I talked my foreman into talking his supervisor into putting that engineer on the floor with me while I did the job
03:11 PM drdoc: his work improved quite a lot
03:12 PM drdoc: ...and I was a rock star around the shop for a while
03:12 PM roycroft: holy, moly, that scared me
03:13 PM roycroft: i installed the td ameritrade destop app today
03:13 PM drdoc: lol
03:13 PM drdoc: get a bubble?
03:13 PM roycroft: i was just doing some work, when i heard this really loud "DING DING DING DING DING DING"
03:13 PM drdoc: ah
03:13 PM roycroft: it's 4pm eastern time
03:13 PM drdoc: right
03:13 PM roycroft: trading just closed at the nyse
03:13 PM roycroft: and the app was letting me know
03:14 PM drdoc: and you thought something was coming unmanufactured
03:14 PM roycroft: i like the app so far, but i don't like that feature
03:14 PM roycroft: i had no idea what was going on at first
03:15 PM drdoc: I gotta go work out this catch-22
03:15 PM drdoc: I need a bigger, stouter gantry plate for this new spindle
03:15 PM drdoc: but I need the new spindle mounted to make it
03:15 PM miss0r2: yay. the lathe sucessfully turned down a piece of cylindrical stock!
03:16 PM drdoc: miss0r2: success!
03:16 PM miss0r2: Now I just need to figure out why the threading part absolutly did not work!
03:16 PM miss0r2: the E-stop came in handy right fast in a hurry
03:17 PM miss0r2: okay.. nothing fits.. *sigh*
03:17 PM miss0r2: Was supposed to be 9.6, but it turned it down to 8.12.... FAK !
03:27 PM JT-Shop: opps
03:27 PM miss0r2: FFS
03:27 PM miss0r2: I figured it out.
03:28 PM miss0r2: Apparently I made the apprentice mistake of reading diameter for radius
03:29 PM miss0r2: well.. that acounts for some of it atleast...
03:35 PM JT-Shop: LinuxCNC control?
03:38 PM Tom_L: miss0r2, i can't view your new design. imgur hates ff
03:39 PM XXCoder: i use ff
03:39 PM * Tom_L feels JT-Shop is in love with windows10
03:39 PM XXCoder: works fine
03:39 PM Tom_L: what version?
03:40 PM Tom_L: this is 87.0 32 bit
03:40 PM XXCoder: jt is a tsundere, in least with windows? lol
03:42 PM Tom_L: it makes the video card flicker on and off
03:42 PM Tom_L: seems to be just that site
03:49 PM * JT-Shop smacks Tom_L with a frozen salmon
03:54 PM miss0r2: tom_l: so.. where do you want it uploaded?
03:55 PM * miss0r2 slaps JT-Shop with a hardback printed edition of the windows ME buglist
03:55 PM miss0r2: just a dab will do
04:06 PM Tom_L: i'll try chrome if i have it on here
04:10 PM Tom_L: works on the other pc
04:11 PM Tom_L: so that works just as good as the previous one?
04:15 PM Centurion_Dan: So what do you guys use for cad these days??
04:15 PM Tom_L: smartcam
04:15 PM Centurion_Dan: er CAD/CAM
04:17 PM Centurion_Dan: I started recently with OpenSCAD, and really love that programming paremetric design approach, but the lack of easy fillet/radius/chamfer is a bit of a struggle. So I'm now taking a dive into FreeCAD - so much better then when I looked at it years ago.
04:19 PM Tom_L: i don't like oscad
04:19 PM Tom_L: freecad is getting better.... slowly
04:22 PM XXCoder: yeah i still remember .13 days
04:22 PM XXCoder: if you looked at wrong section of window, it crashed then lol
04:23 PM XXCoder: next version should be super awesome, with new edge ids
04:23 PM XXCoder: so altering earlier steps shouldnt break eevrything
04:25 PM miss0r2: Tom_L: Yeah, but it looks cooler and takes alot less time to produce
04:25 PM XXCoder: depends on what youre making I guess
04:25 PM Tom_L: less time = mo money
04:25 PM miss0r2: alright, the skim cut doing threading worked fine. the the next cut all but plunged and stalled the thing !!!
04:26 PM miss0r2: tom_L: Indeed
04:28 PM Tom_L: looking at that setup, you didn't want to try softjaws?
04:29 PM Tom_L: you could maybe have had a P1 & P2 and run them together in one jaw set
04:29 PM miss0r2: well, this works fine, and it doesn't leave any real marks. Nothing that won't get removed in the water polish anyway
04:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/A3_P2.jpg
04:30 PM Tom_L: i chamfer the right and left sides in one op
04:30 PM Tom_L: one part is always ahead of the next
04:30 PM miss0r2: Right :)
04:31 PM Tom_L: from the looks of how you did it, you could have made a set i think
04:31 PM XXCoder: tom yeah often used at my last job
04:32 PM Tom_L: since i don't make that many, i just shave it off until it's gone then put on another set
04:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/A3_batch/Batch8.jpg
04:34 PM Tom_L: that was before i had my radius cutters
04:35 PM XXCoder: pretty good
04:35 PM Tom_L: i wish i'd have gotten a couple more
04:36 PM Tom_L: ninja star: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/cutter5.jpg
04:37 PM XXCoder: fancy
04:37 PM Tom_L: never used it
04:38 PM XXCoder: what was orginal reason for bying?
04:38 PM Tom_L: it was free
04:38 PM Tom_L: local tool guy
04:38 PM XXCoder: nice
04:38 PM Tom_L: he gets used cutters as well as new
04:39 PM Tom_L: most of them get sold to scrap by the pound
04:40 PM Tom_L: i had some reason for it but wound up doing something else
04:54 PM roycroft: so the lastest work fun
04:54 PM roycroft: "the phones don't work"
04:55 PM roycroft: this after my boss emailed me earlier saying he deleted a bunch of sip trunks from the sip vendor that we were not using
04:55 PM roycroft: and that was fine
04:55 PM drdoc: lol
04:55 PM roycroft: i confirmed that all the ones we are using were still there, and stil provisioned properly
04:55 PM roycroft: so that was not the problem at all
04:55 PM roycroft: but then i logged into the pbx
04:55 PM roycroft: where are all the trunks?
04:55 PM roycroft: there were none
04:56 PM roycroft: there were no sip trunks
04:56 PM roycroft: there were no inbound routs
04:56 PM roycroft: routes
04:56 PM roycroft: there were no outbound routes
04:56 PM roycroft: so i asked my boss
04:56 PM roycroft: he said "yeah, i deleted a bunch of stuff we don't need from the phone switch, but all the extensions, announcements, and voicemail boxes are still there"
04:57 PM roycroft: i'm like "um, and you deleted all the sip trunks, inbound routes, and outbound routes"
04:57 PM roycroft: and he still yells at me for refusing to give him the passwords for the network switches/routers/firewalls
04:57 PM XXCoder: geez
04:58 PM roycroft: i'd rather get yelled at than give up those passwords
04:58 PM drdoc: amen
04:58 PM roycroft: so i just forwarded all the incoming trunks to his cell
04:58 PM roycroft: and told him i'd rebuild the pbx tomorrow
04:58 PM drdoc: you scared my cats
04:58 PM drdoc: :-D
04:58 PM roycroft: and that i won't get the other work done that he wanted me to do
04:59 PM roycroft: the scary thing is - i don't think he's sabotaging things on purpose
04:59 PM roycroft: if he were just being an asshole that's more understandable than this
04:59 PM drdoc: not much to understand
05:00 PM drdoc: intelligence is really knowing when you don't know
05:00 PM roycroft: and in part, given that he's in his mid-70s now, knowing that you don't know what you used to know
05:00 PM roycroft: although he's always been like this to a degree
05:00 PM roycroft: it's getting a lot worse now
05:01 PM roycroft: oh well, 12 more minutes and i'm done for the day
05:01 PM roycroft: i'm hoping to finish my blasting cabinet today
05:01 PM roycroft: if the caulk has kicked off finally
05:02 PM roycroft: i have to cut a piece of glass for the view window, screw the door back on, and do a little painting on the outside, once i clean up the caulk
05:02 PM roycroft: so it's really only a half hour of work yet to go
05:11 PM Tom_L: 2 min
05:17 PM drdoc: shazzbat
05:17 PM * drdoc forgot to order belt & pulleys
05:18 PM Tom_L: what series belt?
05:19 PM drdoc: probably 3GT
05:19 PM drdoc: since I need both pulleys and a belt, whatever works...
05:20 PM Tom_L: GT3 is harder to find than GT2
05:20 PM drdoc: 75mm center to center, 8mm bores
05:20 PM drdoc: true
05:20 PM drdoc: I guess a wide GT2 would do fine - it's a ~250in/oz stepper driving it
05:22 PM drdoc: I have a ton of GT2 pulleys, all 5mm bores
05:22 PM Tom_L: i think i used something else on my z stepper but did use GT2 15mm wide on the spindle
05:22 PM drdoc: XL is really easier to find in this size
05:23 PM Tom_L: i think i did use xl on that
05:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Motor_Mounted2.jpg
05:23 PM Tom_L: spindle
05:23 PM drdoc: yup
05:24 PM drdoc: you sure that isn't 3mm?
05:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Motormount2.jpg
05:24 PM Tom_L: z axis
05:24 PM drdoc: yes
05:24 PM Tom_L: it's 5mm
05:24 PM Tom_L: the spindle
05:24 PM drdoc: ah
05:24 PM Tom_L: 15 wide
05:25 PM drdoc: right
05:26 PM drdoc: the problem with XL is that when you go looking for belts, what you get is fashion accessories for big women
05:26 PM Tom_L: sdp-si
05:27 PM Tom_L: use their center distance calculator
05:27 PM drdoc: got that page up
05:27 PM * JT-Shop is finally making forward progress on the machine...
05:30 PM Tom_L: JT-Shop, which machine?
05:33 PM JT-Shop: spoke lathe feeder
05:34 PM Tom_L: ahh yeah
05:35 PM JT-Shop: finally got the pneumatics in so I can get back to design/build
05:37 PM drdoc: Tom_L: boo-yah! Found XL pulleys & belt to fit for next-day delivery.
05:37 PM drdoc: I'll order a *good* set if they fit. ;-)
05:41 PM Tom_L: i generally have to bore one of them
05:51 PM drdoc: Hmmm. I just figured out why this stepper motor was free
05:52 PM drdoc: Inductance: 9mH +/- 10%
05:52 PM drdoc: ow.
05:52 PM drdoc: I guess driving Z that will do
05:53 PM Tom_L: my z has gobs of torque
05:53 PM Tom_L: with 570 in oz 3:1
06:01 PM snakedGT is now known as snaked
06:47 PM Lcvette: hey all, what brand model touch screen are you guys using with success in debian 10 buster?
06:55 PM roycroft: i have an old elo touchscreen that worked fine until i installed buster, and now it's really flaky and unusable
06:56 PM roycroft: that's an answer to the opposite of what you asked, but it may be apt
06:56 PM * Lcvette uploaded an image: (20KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/yHiRSJdRIRcRxuCkADziutoA/Screenshot_2021-04-06_19-44-07.png >
06:57 PM Lcvette: hmmm
06:57 PM Lcvette: i have not tried my elo machine on buster 10 yeat
06:57 PM roycroft: that machine is on my workbench right now, actually, and i mean to work on it very soon
06:57 PM Lcvette: * i have not tried my elo machine on buster 10 yet
06:57 PM roycroft: it has a tiny wifi adapter that needed some m2.5 screws to secure, and i just got that done the other day
06:57 PM roycroft: the touch screen is the next thing to tackle
06:58 PM roycroft: btw, things going to plan is great
06:58 PM roycroft: my blasting cabinet is working again, and i'd say a conservative estimate is that there is a 200-300% improvement in efficiency
08:54 PM Bleepshop: roycroft: I've got 2 ELOs, you may need to download the calibration tool from them and run it in a Windows VM to get the NVRAM in the screen set properly.
08:56 PM Bleepshop: One is a POS terminal and the other one is in an old Rock-Ola internet connected jukebox I converted for shop tunes.
08:57 PM -!- #linuxcnc mode set to +v by ChanServ
09:02 PM roycroft: thanks, i'll look into that
09:02 PM roycroft: it did work fine until buster, though
09:05 PM Bleepshop: I had problems with teh one in the Rock-Ola right from Go. It used to be a Win CE machine and I had to totally redo the screen calibration when I swapped it over to Fedora 33 with Kodi.
09:12 PM roycroft: i've spent almost no time sorting out the problem with buster
09:12 PM roycroft: what little time i've had to work on that machine i've spent getting the wifi adapter working
09:12 PM roycroft: that's done, so the touch screen is the next thing

09:36 PM snakedGT is now known as snaked
09:42 PM skunkworks: hmm - I must have made it big time... I see ads at the begining of my videos now...
09:46 PM roycroft: youtube is almost intolerable now
09:46 PM roycroft: it's full of vile, nasty political and gun ads that cannot be skipped
09:47 PM roycroft: one used to be able to skip those
09:49 PM Tom_L: roycroft, you use adblocker?
09:49 PM roycroft: i do use an adblocker, but it does not work on youtube any more
09:49 PM Tom_L: or uBlock
09:49 PM Tom_L: seems to on mine
09:50 PM roycroft: if i'm not watching a live stream i try to download youtube videos
09:50 PM roycroft: and that's enough effort that i don't watch many of them any more
09:50 PM roycroft: our election is long over - i really don't know why there are so man political ads now, and why they cannot be skipped any more
09:52 PM roycroft: i used to like to watch youtube videos on my big tv in my living room, but there are no ad blockers for that
09:52 PM roycroft: so i get even more ads when i do that
10:10 PM skunkworks: Huh. I get very few ads that I consider bad.. Mostly 3d printing, machining, random stuff.
10:11 PM skunkworks: I ignore them mostly.
10:11 PM skunkworks: Never used an ad blocker. (very good at tuning things out)
10:11 PM roycroft: i don't get why i get so many horrible ads
10:12 PM roycroft: i do not own any guns, and i am not interested in owning any, yet i get all sorts of "self defense" and "firearm safety course" ads
10:12 PM roycroft: sometimes 3-4 of them in a single video
10:12 PM roycroft: and i get heaps of "the government won't let us do what we want" political ads
10:13 PM roycroft: basically, i get inundated with ads that i find highly offensive and completely antithetical to who i am and what i believe in
10:13 PM roycroft: somehow youtube think i'm a redneck moron or something
10:14 PM Tom_L: :)
10:15 PM Tom_L: damn hippie
10:15 PM skunkworks: Do you live in redneck country?
10:15 PM Tom_L: orgon
10:15 PM Tom_L: oregon
10:15 PM * skunkworks doesn't know if that is redneck country..
10:15 PM Tom_L: i'd guess the complete opposite end of the US for rednecks
10:16 PM roycroft: oregon has a lot of rednecks
10:16 PM roycroft: and a lot of hippies
10:16 PM roycroft: and a lot of portlandians
10:16 PM Tom_L: i'm probably just North of 'pure' redneck country :)
10:16 PM skunkworks: odd. wonder why? I do get a random political ad from time to time - but it is usually aligned to mine..
10:17 PM roycroft: i think actually youtube know that i find those ads offensive, and keep showing them to me to try to coerce me into giving them money for their premium ad-free service
10:17 PM skunkworks: Hmm - maybe. Evil!
10:17 PM Tom_L: you must do something somewhere to let them know...
10:18 PM Tom_L: a while back we were driving by a place and i asked the Mrs what something was. by the time we got home we both had received emails about it
10:18 PM roycroft: siri or alexa must have been listening
10:19 PM Tom_L: google
10:19 PM roycroft: i use duckduckgo as my search engine
10:19 PM Tom_L: but neither of us were actively using the phone
10:20 PM roycroft: and i don't seem to get tracked as well as when i used google
10:21 PM Tom_L: the only thing that really bothers me is the spam calls i get during the day
10:21 PM roycroft: 90+% of the calls i get on my cell are spam
10:21 PM Tom_L: i think i had 4 today
10:22 PM roycroft: 4-6 are about average for me
10:22 PM roycroft: per day
10:22 PM roycroft: and usually at least a couple on the land line
10:22 PM Tom_L: but i use my phone during my work so i feel obligated to answer it
10:22 PM roycroft: my cell phone is a work phone
10:22 PM Tom_L: for a long time i was blocking the numbers but it did little good
10:23 PM roycroft: i do have to answer it whenever it rings during work hours
10:23 PM Tom_L: same here
10:23 PM roycroft: the spammers are spoofing local numbers now, which makes it even worse
10:26 PM ziper: are higher temper aluminum alloys easier to file?
10:26 PM Tom_L: probably won't gum up as bad
10:28 PM Tom_L: T6 is pretty common
10:28 PM ziper: thats what I was thinking
10:29 PM Tom_L: and i dunno the difference between T6 and T651 but i have a little of both
10:29 PM Tom_L: i'm sure it's the process but don't know what
10:29 PM Tom_L: maybe age hardening
10:30 PM Tom_L: https://www.cnclathing.com/guide/difference-between-t6-and-t651-aluminum-tempers-designation-system-explain-cnclathing
10:31 PM ziper: I really just mean between t6 and untempered
10:31 PM Tom_L: i know but i was curious and shared
10:31 PM ziper: i see
10:32 PM Tom_L: stress relieved and T6 isn't
10:33 PM Tom_L: for example when you run a shell mill across it, T6 will tend to warp more than T651
11:15 PM pcw_home: I get lots of adds for 50K Tek MSOs
