12:40 AM Lcvette: Doesn't work on my tablet
12:47 AM fragalot: Hi.
12:51 AM IchGucksLive: morning from germany
12:52 AM fragalot: Hi
12:55 AM IchGucksLive: fragalot, im starting to feel the effects people leving lcnc as on update lcnc nothing works
12:55 AM fragalot: :/
12:55 AM IchGucksLive: you realy need to get all config stuff renued
12:56 AM IchGucksLive: the big mashine im using here moves only 15mm/min
12:56 AM IchGucksLive: all axis nothing more
12:56 AM fragalot: wtf happened >.<
12:56 AM IchGucksLive: its only a 2.7.12 to 2.7.13 change
12:56 AM fragalot: things like this is why industry lags behind so much.
12:57 AM fragalot: everyone is afraid of updates and prefer to keep the minor bugs or inconveniences of the old version over a potential new issue
12:57 AM IchGucksLive: now i see Axis_0 i got Joint_0 or axis_x
12:57 AM IchGucksLive: there is now a version number that also effects the mashine
12:58 AM IchGucksLive: why does trivkins now put in kinetics INI
12:58 AM IchGucksLive: EMC line mixes it up num_joint Tray Axis
12:59 AM IchGucksLive: i got 4 schools working together on projekt with this isssues imposible to comunicate on settings
01:00 AM fragalot: is it possible to downgrade?
01:01 AM IchGucksLive: i dident see this at all and coudent belve people telling now as i installed 6 more systems yesterday in school i do belive them
01:01 AM IchGucksLive: i personly think that Ncam has a huge impact on the system
01:01 AM IchGucksLive: as it is now loaded at all configs first
01:02 AM IchGucksLive: without ini setup
01:02 AM IchGucksLive: this DEB packet might be the Worm / bug
01:02 AM IchGucksLive: i will setup the next 6 without ncam and see
01:03 AM IchGucksLive: guten morgen holzjunkie
01:04 AM IchGucksLive: im off 2 garden
01:05 AM IchGucksLive: fragalot, my personal statistics say we are in production of the 500th CNC mashine for schools
01:05 AM fragalot: good job! :D
01:07 AM holzjunkie: fragalot: hy
01:07 AM fragalot: Hello
02:34 AM Deejay: moin
04:15 AM Loetmichel: *GNHIHIHI* ... $me just cut a cable to long and i scolded myself (loudly) "OCH MICHEL! DU HAST DOCH EIN AUGENMASS DAS GEHT AUF KEINE KUHHAUT!" ... from five different directions you heard an "echo" in slightly different accents: "OOOOCHHH MICCCHEEELL!!!!" :-)
05:45 AM jthornton: morning
05:45 AM XXCoder: yo
05:55 AM jthornton: odd sunrise is 5:52 but the door doesn't open till 5:56... I wonder whats wrong with my code
05:55 AM XXCoder: it depends on sunrise calculation?
05:56 AM SpeedEvil: Are you on top of a tall mountain?
05:57 AM SpeedEvil: Also, you are remembering the sun has a finite diameter?
05:57 AM jthornton: the door should open at sunrise if no extra light is needed and now that I have 14+ hours of daylight no extra light is needed
05:58 AM SpeedEvil: (time to get a quarter of a degree over zero degree horizon from initial view of the sun may be >1min
05:58 AM SpeedEvil: Especially if northerly
05:59 AM XXCoder: in some reasons crossing horzon takes few hours and it changes mind and start sunset before finishing sunrise
05:59 AM XXCoder: *areas dammits words fail me
05:59 AM * jthornton wonders what we are talking about now
06:00 AM SpeedEvil: Sun worship.
06:00 AM Tom_L: global warming?
06:01 AM Tom_L: it gets blamed for everything
06:01 AM SpeedEvil: It turns out the real reason for global warming is that the sun is rising 4 minutes early
06:01 AM SpeedEvil: That'd add up.
06:02 AM SpeedEvil: jthornton: Also - incorrect position by some 100km would do that
06:03 AM jthornton: do what?
06:03 AM XXCoder: sunrise time error
06:03 AM XXCoder: 100km would be still be within same timezone for most timezones in usa, horzionally
06:04 AM SpeedEvil: jthornton: 100km will offset it by around 4 minutes
06:04 AM SpeedEvil: (east-west)
06:04 AM * jthornton still wonders what we are talking about
06:05 AM XXCoder: sunrise time vs actua;
06:05 AM XXCoder: west border of timezone would have different sunrise time than east border
06:05 AM XXCoder: 6 minutes is very possible
06:05 AM Tom_L: dense cloud cover over Poplar Bluff is the culprit
06:06 AM Tom_L: or you forgot to wind the mainspring
06:10 AM * jthornton gets the microscope out to look for a spring
06:11 AM jthornton: https://paste.ubuntu.com/p/Xkb9rHTMB4/
06:11 AM XXCoder: why? spring is everywhere!
06:11 AM XXCoder: ;)
06:11 AM jthornton: we didn't get a spring
06:12 AM XXCoder: here it went directly to summer, then directly to fall type weather
06:13 AM XXCoder: weather here gets worse each year
06:13 AM jthornton: https://paste.ubuntu.com/p/77CSHhk7vX/
06:14 AM XXCoder: is today first day it decides time open based on sunrise time>?
06:14 AM jthornton: no that happened the other day
06:14 AM jthornton: I think the door has been opening a bit later each day for some reason
06:15 AM XXCoder: wonder if theres dirty data error
06:16 AM XXCoder: basically it reuses variable and as result theres calculation error
06:18 AM XXCoder: dont look like anything that could cause that
06:19 AM XXCoder: im not too familiar with your system, but when does "root code" run? meaning its not in function
06:19 AM XXCoder: lighton = timezone('US/Central').localize(datetime.datetime.now())
06:19 AM XXCoder: for example
06:20 AM jthornton: might be a problem with the web page it tosses up reporting door open time as lighton.strftime(timeformat)
06:20 AM XXCoder: does your device call entire code timed?
06:21 AM jthornton: not sure what your asking
06:21 AM XXCoder: well im not familiar on how your device works with source code you posted
06:22 AM XXCoder: does it call script each day or whatever, or only when it powers on and it calls itself sometimes?
06:23 AM jthornton: it's running on a RPi and runs all the time, the status function is run each minute and the update is ran at 2am each day
06:23 AM jthornton: update is what sets the sunrise/sunset times etc each day
06:23 AM XXCoder: so rpi loads this python script and it runs itself as long as its powered on?
06:24 AM jthornton: yes, the script is run as a service on the RPi
06:24 AM XXCoder: ahh found it;. i was wondering where lighton gets updated
06:26 AM XXCoder: I guess lighton.strftime(timeformat) is api fnction call to control hardware?
06:27 AM jthornton: no, it's just a variable formated in the timeformat
06:27 AM XXCoder: oh yeah forgot that some types has builtin functions
06:28 AM XXCoder: been too long
06:28 AM XXCoder: how do it send data to control light and door?
06:28 AM XXCoder: ah GPIO
06:29 AM jthornton: if not lights:
06:29 AM jthornton: if sunrise < now and now < dusk:
06:29 AM XXCoder: is that set pin high or low or whatever?
06:29 AM jthornton: that is what opens the door
06:29 AM jthornton: yea
06:29 AM XXCoder: cool. I do want to learn to do stuff like that but dunno if will lol
06:29 AM jthornton: ok it's only a web page issue the door opened at sunrise
06:30 AM XXCoder: I still remember this insane bug in my code that I took all day to find
06:30 AM jthornton: I tried for years to learn C but never had a reason to use it so it never stuck
06:30 AM XXCoder: it was simply missing var->pointer = null;
06:30 AM XXCoder: c isnt that different from python honestly
06:31 AM XXCoder: it dont care about whitespace unlike python though lol and some differences like -> for dereference
06:32 AM jthornton: yea lighton is a stale variable and is the wrong one to report door open time
06:34 AM XXCoder: maybe just need some lookup table as backup
06:36 AM XXCoder: https://www.kickstarter.com/projects/1252280491/myst-25th-anniversary-collection/posts/2189271
06:36 AM XXCoder: only week left for myst kickstarter heh
06:37 AM jthornton: no, I just need to use the actual door open time not the lighton time in the web page
06:43 AM jthornton: hmmm firefox locked up again
06:44 AM XXCoder: cool :)
06:44 AM XXCoder: dunno on ff
06:44 AM XXCoder: it happened to me, but it was because firefox updated while still open
06:45 AM miss0r: hello people o/
06:45 AM XXCoder: hey person
06:45 AM miss0r: ^^
06:46 AM miss0r: did you just assume my race?
06:46 AM XXCoder: race is not species. :)
06:46 AM miss0r: species then ;)
06:46 AM miss0r: Does that quality for a "metoo" campaign? :P
06:46 AM XXCoder: also, aliens can be people, specist!
06:46 AM * jthornton doesn't race any more
06:47 AM miss0r: My shop looks like someone pulled the pin on a handgrenade in here
06:47 AM jthornton: my bme280 arrived yesterday
06:47 AM XXCoder: thought you was planning to clean up?
06:47 AM miss0r: XXCoder: I've only gotten to that part now. Apparently a few people with machine issues decided to call me
06:48 AM jthornton: fixed the code https://paste.ubuntu.com/p/xWpNw5vhWT/
06:49 AM miss0r: can't complain about that tough, its what I do for a living :]
06:49 AM jthornton: now to clean up the door open part
06:49 AM XXCoder: indeed miss0r
06:49 AM jthornton: I hear ya, I've had more work than I've had in a long time the last year... had to pay taxes for once
06:50 AM miss0r: jthornton: for once? sounds serious :D
06:51 AM jthornton: well it was a few years not making enough to have to pay taxes and I was investing a lot in equipment and buildings
06:51 AM miss0r: Keep in mind I live in Denmark... I think we are number 2 or 3 on the list of most taxed countries in the world
06:51 AM jthornton: and had a lot of time to do stuff with no work
06:51 AM miss0r: When I embarked on selfemployment, I thought I would have a little more time to tinker around with things. It turns out, so far, I was mistaken
06:52 AM jthornton: I've been to Denmark a few times to visit the Enkotec company
06:52 AM miss0r: Indeed
06:53 AM XXCoder: I would love self-employment but I got no idea on what
06:53 AM XXCoder: also, im not sure if I'd be good boss to myself
06:53 AM miss0r: heheh. I have that same issue, my boss is a dick :D
06:53 AM jthornton: ENKOTEC A/S Head Office & Factory Sverigesvej 26 DK-8660 Skanderborg
06:53 AM XXCoder: I'd be opposite, I'd allow my employee to slack off all time
06:54 AM miss0r: XXCoder: Just figure out what you love to do, and then see if it os possible to make a living from
06:54 AM jthornton: yea same here my boss is a workaholic bastard
06:54 AM miss0r: :]
06:54 AM miss0r: He would rather drive me 6' under, than give me some time off
06:55 AM miss0r: I'm pretty psyched about going to germany next week. First international client
06:55 AM jthornton: cool
06:55 AM miss0r: They were willing to pay me 0.75eur pr kilometer i drive to get there + my hoursly wage
06:56 AM miss0r: so I make some pretty decent money while spinding ~6 hours in my car each way
06:56 AM XXCoder: whats you do in general? machine maintance and repair?
06:56 AM miss0r: That is what I love about the machining market here. people pay up!
06:57 AM miss0r: XXCoder: Yeah. I also build addon machinery
06:57 AM miss0r: even small machines
06:57 AM XXCoder: man we need you there at shop :P one machine soon finished on MAJOR tuneup, 2 machines broken
06:57 AM XXCoder: you willing to fly to usa for free? anmd work for free since I cant pay you, since I am not boss of company ;)
06:57 AM miss0r: You are more than welcome to place an order ;)
06:58 AM miss0r: hehe. I think my actual boss(wife) would have issues with that ;)
06:58 AM XXCoder: I bet! lol
06:58 AM miss0r: I wouldn't mind traveling a little more as a professionally.
06:59 AM miss0r: I love getting a bit around and see new stuff
06:59 AM XXCoder: I love traveling but no idea what to do professionlly that would need travel time
06:59 AM jthornton: I had to go to a plastic injection factory yesterday an assembly machine was messing up on station 3... after about 2 hours I finally sorted out the home switch on the indexer was worn out
06:59 AM miss0r: Hehe. If you are good enough/huge demand for what you can do, it just handles itself
07:00 AM miss0r: jthornton; Pretty satisfying, ha?
07:00 AM miss0r: I get a kick out'a repairing machine tools
07:01 AM miss0r: XXCoder: You could do what I do?
07:02 AM XXCoder: nah
07:02 AM miss0r: why not? you like to tinker as well
07:02 AM XXCoder: im great cnc operator, weak cnc machinist
07:02 AM XXCoder: yeah never was good, but did do some stuff, like modify 3d printer
07:04 AM jthornton: miss0r: yea I love solving problems and interesting ones like that the problem was not even at the station
07:04 AM miss0r: If people ask me to look at something, I just say: sure. Thinking to myself, I can learn that along the way :]
07:04 AM jthornton: I've worked on that machine so many times I printed out the PLC ladder and have it in a binder
07:06 AM miss0r: yeah.. I have to go look at a mill tomorrow, I've done some repairs on. on that particular machine, I have hired in a siemens PLC programmer to come help out. I don't have 50k eur to spend on a lisence for that PLC :D
07:07 AM miss0r: enough talk.. I need to start cleaning in here
07:08 AM XXCoder: have fuj
07:08 AM XXCoder: fun
07:08 AM miss0r: don't worrie, that won't happen
07:10 AM jthornton: wow 50k for a license for siemens plc?
07:44 AM miss0r2: apparently cleaning the shop in a white t-shirt is a bad choice... Who would've known
08:32 AM miss0r2 is now known as miss0r
08:44 AM miss0r: there we go. Now the drill press, the cnc mill and the lathe is cleaned... *sigh* Now for the rest of the shop
08:49 AM SpeedEvil: https://science.ksc.nasa.gov/shuttle/missions/51-l/docs/rogers-commission/Appendix-F.txt On failure.
09:34 AM miss0r: Do you guys know what those gear up units for milling spindles are called? like a 1:3 ratio or something
09:35 AM gregcnc_: spindle speeder
09:35 AM miss0r: Excellent. thanks
09:37 AM miss0r: It would seem that is yet another thing I want, that will make me go bankrupt.
09:38 AM gregcnc_: used market?
09:39 AM miss0r: Still expensive.
09:40 AM gloops: hmm, 25mm radiator bagging seems perfect to make a sleeve on planer roller - if i can get it on
09:41 AM miss0r: My local tool pusher just called me, telling me about a great offer they have at the moment: An electric spindle add-on for my ISO40. It does from 2000 to 55000 rpm. its equipped with a ER11 collect. But it is only 350watt. AND it costs ~3500 eur
09:41 AM gregcnc_: was going to say build an electric spindle
09:41 AM miss0r: So I started looking at gearheads, as I have landed a pretty big order that requires me to run with some quite small endmills
09:41 AM gregcnc_: you wont' need more than 350W for ER11 spindle
09:42 AM miss0r: hmm.. true
09:42 AM miss0r: still.. you can strap a 6mm endmill in an er11... I wouldn't run a 6mm with 350watts any day of the week
09:43 AM gregcnc_: if you intend to run a lot of 6mm tools look at the power curve
09:43 AM gregcnc_: and duty cycle
09:43 AM miss0r: yeah. I'm not going to buy that spindle add-on. Its more money than I payed for the cnc mill
09:44 AM miss0r: I might go ahead and buy a chinesium on(one of the better chinesium ones) and make a bracket to fit it to the mill, for the operation at hand
09:44 AM miss0r: chinesium spindle, that is
09:44 AM miss0r: This looks like quality: https://www.ebay.co.uk/itm/CNC-400W-Spindle-Motor-ER11-Mach3-PWM-speed-controller-Mount-engraving-set/111938787450?epid=627874500&hash=item1a1012587a:g:U~EAAOSwT6pVxVxR
09:45 AM gregcnc_: buy 5 and mount them on a bar to cut your production time?
09:46 AM gregcnc_: are there "better" chinese spindles or just resellers that actually inspect and offer some support for higher price
09:48 AM miss0r: Yeah. I'm thinking of getting one with a vfd. I just hate how little information theres available on fleabay. Like; I can't tell if its a single phase or three phase VFD. so the fact that they write 220-250 volts, would be alright for me, if its a single phase.. but I don't have that low voltage available here for three phases
09:49 AM gregcnc_: I think they are all single phase, you don't have a suitable VFD laying around?
09:49 AM miss0r: They are too big
09:49 AM miss0r: hehe.. I even have two that are too small. only 200 watts
09:49 AM miss0r: or maybe 250, I can't remember
09:50 AM Rab: Wonder if that motor has sleeve bushings instead of bearings.
09:50 AM gregcnc_: i don't think I've ever seen any that small, even in catalogs
09:50 AM miss0r: rab: I've come across those motors before. They have a TINY ball bearing in the front, and a brass bushing in the rear
09:51 AM miss0r: Its a thin shaft comming out of the motor, with a 'beefy' er11 shank pressed on there. Everything about it is awfull
09:51 AM miss0r: gregcnc_: home made
09:52 AM miss0r: hmm.. if I go ahead and get a 2.2kw one, I better choose the watercooled one, I think
09:52 AM miss0r: Otherwise it will undoubtedly get too hot in a hurry
09:55 AM miss0r: also, a spingle advertised for 8-24k rpm with sealed grease filled bearings? am I the only one that finds that shady ?
10:08 AM SpeedEvil: 'guaranteed sealed, with a operating temperature of no less than 250C at 24Krpm'
10:18 AM hazzy-dev: miss0r: woodworking equipment frequently uses grease lubed bearings in 30K + spindles, low load, but last a long time and run plenty cool
10:18 AM hazzy-dev: so it can be done with quality bearings and low preload
10:22 AM rmu: older woodworking spindle here has 2 pairs of 15° angular contact P4 ball bearings, not sealed
10:22 AM rmu: up to 24krpm
10:23 AM rmu: grease lubricated
10:25 AM gregcnc_: proper bearings and grease
10:31 AM hazzy-dev: proper grease being Kluber
10:31 AM hazzy-dev: :D
10:33 AM hazzy-dev: Actually Klüber grease
10:33 AM hazzy-dev: (the sideways colon makes all the diff)
10:42 AM gloops: the 250v is a bit misleading, the vfd takes 250v, the spindle is 3 phase
10:43 AM gloops: when i first looked at them i messaged the chinese seller asking if the spindle was 250v - reply 'it says 250v'
10:43 AM gloops: me thinking i could just buy the spindle and run it from the 240v mains
10:44 AM gloops: (single phase)
11:17 AM lcvette: Gloops you need 3 phase power?
11:17 AM lcvette: or a vfd?
11:17 AM rmu: gloops: why is it misleading
11:19 AM lcvette: if he is new to motors and ac power of industrial nature i can see it being confusing
11:20 AM rmu: in europe, 3 phase power and 3 phase motors are quite common. but i don't know situation in UK
11:22 AM lcvette: yeah not sure where he is
11:22 AM lcvette: in the US, all residential is single phase power
11:23 AM lcvette: only industrial and commercial gets 3 phase power
11:23 AM gregcnc_: you still need a VFD for a 400hz spindle
11:23 AM lcvette: so if we want 3 phase power for a larger machine we need either a digital or rotary phase converter
11:24 AM lcvette: correct
11:24 AM gregcnc_: yeah that sucks
11:24 AM rmu: do rotary phase converters still exist? are they installed in new installations?
11:24 AM gloops: it was misleading to me who doesnt know anything about electronics, 240-50 volts implied the spindle was single phase
11:24 AM lcvette: i just installed one
11:24 AM lcvette: in my shop
11:24 AM lcvette: 25hp
11:24 AM gregcnc_: rotary probably makes up 95% of the market
11:27 AM rmu: and that thing really is an electric motor and a synchronous generator? coupled together?
11:27 AM gregcnc_: digital converters are still super expensive
11:27 AM gloops: 3 phase is pretty standard for commercial concerns here
11:27 AM lcvette: its just a motor all in one
11:27 AM lcvette: no coupling
11:27 AM rmu: jeah, its' probably one case
11:27 AM gregcnc_: one stator
11:27 AM rmu: does it have brushes?
11:27 AM gregcnc_: no
11:27 AM gregcnc_: you can use a three phase motor as a converter
11:27 AM rmu: how does it run on single phase... capacitor?
11:27 AM rmu: ok
11:27 AM gregcnc_: capacitor start, capacitors to balance the output pahses
11:27 AM gregcnc_: but phase perfect is nice
11:28 AM lcvette: super high tech
11:28 AM lcvette: lol
11:28 AM lcvette: mine is not
11:28 AM gregcnc_: blue one?
11:28 AM lcvette: no mine is a basic capacitor bank RPC
11:28 AM lcvette: it is balanced
11:29 AM lcvette: quite well i might add
11:29 AM rmu: this all is beyond stupid
11:29 AM lcvette: but not a phase perfect
11:29 AM rmu: what is the machine doing with 3 phase power?
11:29 AM rmu: surely the spindle motor has some kind of VFD
11:29 AM gregcnc_: spindle motors
11:29 AM lcvette: and servo motors
11:29 AM rmu: and the servo amps also have some DC tank circuit
11:30 AM lcvette: my spindle is 5.5kw
11:30 AM rmu: so you go AC single phase -> AC 3 phase -> DC (in VFD / servo amp) -> some kind of vector controlled 3phase
11:30 AM lcvette: too big for single phase
11:30 AM gregcnc_: not entirely true
11:30 AM gregcnc_: but when they build the machine they don't oversize the drive for single phase input
11:30 AM rmu: lcvette: but you go single phase -> 3 phase in the first place, so it't not too big for single phase
11:31 AM Loetmichel: gregcnc_: REALLY? 95% of the market? at the current iron and copper prices?
11:31 AM Loetmichel: VFDs are much cheaper for the same power, are they not?
11:31 AM gregcnc_: 1/5 the price
11:31 AM rmu: gregcnc_: what do you mean with "don't oversize the drive"?
11:31 AM lcvette: i understand they could over size the drive but that isn't recommended above 5 hp
11:31 AM rmu: why do you have to oversize the drive for single phase input?
11:31 AM gregcnc_: the drive must be over size to run single phase input
11:31 AM gregcnc_: compared to 3phse input
11:32 AM rmu: why?
11:32 AM gregcnc_: you tell me?
11:32 AM gregcnc_: the power side must ba capable of the input current
11:32 AM rmu: it probably needs a PFC, but that is advisable with 5KW even with a rotary phase converter
11:32 AM lcvette: my spindle is a servo spindle
11:32 AM rmu: input current is not less in 3 phase case, only divided on 3 phases
11:32 AM gregcnc_: exaclty
11:33 AM rmu: yes, but this current ultimately is supplied by one phase
11:33 AM gregcnc_: most 3ph drives will allow derated 1ph input
11:33 AM rmu: yeah, because they use cheap 6 diode rectification
11:34 AM rmu: in europe, VFDs above some specific power rating need to have active PFC
11:34 AM gregcnc_: i don't design them, just what i've read in manuals and by other who do stuff with them they aren't rted for
11:34 AM rmu: in case of one-phase supply, a single phase PFC is much simpler than 3phase PFC
11:34 AM Loetmichel: rmu: probably all, becasue the power rating is 100W iirc
11:35 AM rmu: hmm. strange
11:35 AM rmu: nevermind
11:36 AM lcvette: in either case.. my RPC works
11:36 AM lcvette: :)
11:36 AM gregcnc_: yes probably keep the shop warm in winter, but summer?
11:36 AM lcvette: inverstment was $1400 shipped
11:36 AM lcvette: it actually doesn't get very warm
11:36 AM rmu: this really is technology that should have dies 100 years ago ;)
11:36 AM gregcnc_: what is idle current>
11:36 AM rmu: died
11:37 AM lcvette: i dunno
11:37 AM lcvette: haven't checked it
11:37 AM gregcnc_: that will tell you real losses
11:37 AM lcvette: where should i check?
11:38 AM gregcnc_: it's about 10-12A for a 25HP, only >2kW
11:40 AM lcvette: is that good or bad?
11:40 AM gregcnc_: just is. basically all the becomes heat in the shop
11:41 AM lcvette: guess its good i have a climate controlled shop
11:41 AM lcvette: lol
11:42 AM lcvette: mid 90's outside and a nice 68 degrees in the shop, i like it cool
11:43 AM Loetmichel: hihi
11:45 AM * Loetmichel just sat in his convertible without any A/C... all day sun on the closed black canopy.. and a few leaks the last few months. so i got in and felt like i entered a turkish sauna fully clothed... HAD to open the canopy to drive the car ;)
12:01 PM fragalot: Hi
12:12 PM CaptHindsight: old leaky convertibles are just giant mold and mildew petri dishes
12:12 PM IchGucksLive: hi
12:12 PM Rab: Expand that to most old cars. Once the side window or trunk seals go, it's over.
12:12 PM fragalot: CaptHindsight: what makes you say that? :P
12:13 PM CaptHindsight: for added fun leave some food in the trunk over the summer
12:14 PM IchGucksLive: Q at all is there a Reload g-code button in Gmoccapy
12:19 PM CaptHindsight: old car horror stories
12:19 PM fragalot: CaptHindsight: but the mold is what keeps the seats soft
12:21 PM Rab: Gotta have something, after the leather takes on the consistency of wood veneer.
12:22 PM gregcnc_: my interior is just falling off
12:22 PM IchGucksLive: university just called in the mashine has burned off Ouch
12:23 PM IchGucksLive: the old mashines around the education getting wear
12:23 PM gregcnc_: students found self destruct button?
12:24 PM IchGucksLive: i think so
12:24 PM CaptHindsight: how else will they learn?
12:24 PM fragalot: beatings.
12:24 PM IchGucksLive: in the last 10 years the mashine never worked that hard
12:25 PM IchGucksLive: they are up on 24 mashines till oktober
12:25 PM IchGucksLive: selfmade
12:26 PM CaptHindsight: the proof is in the pudding
12:27 PM CaptHindsight: sounds like smart kids
12:27 PM fragalot: or a good teacher
12:27 PM IchGucksLive: i had this more then once
12:28 PM IchGucksLive: if mashines stay in corner or basement wet place for years
12:28 PM IchGucksLive: then get reaktivated on a 6+ hr shift for weeks
12:28 PM IchGucksLive: they might get broken
12:29 PM IchGucksLive: they are told to clean change oil hydraulik and make the check
12:29 PM CaptHindsight: how they learn about electrolytes, oxidation, rubber boots vs rubber gloves and live wires, etc etc
12:30 PM CaptHindsight: why ground fault protection was in vented
12:30 PM IchGucksLive: im off for today need to close the garden down as night temps fall around 5Deg
12:45 PM gloops: w..t
12:46 PM gloops: trial with 10mm foamex covered with chrome vinyl - cuts well but upcut spiral snags vinyl, may work with downcut
01:01 PM gloops: actually the mrs has just pointed out that its the clear protective film thats snagged lol, its pretty good
01:05 PM phipli: Hum. I've got greenfly
01:05 PM phipli: Never had so many stowaways on the cycle home
01:10 PM CaptHindsight: better than bringing home crabs
01:12 PM gregcnc_: why does luggage need to be smart?
01:15 PM fragalot: gregcnc_: so it can track you.
01:15 PM fragalot: https://www.discworldemporium.com/829-thickbox_default/the-luggage.jpg
01:16 PM gregcnc_: https://www.engadget.com/2018/05/17/smart-luggage-company-raden-shuts-down-airline-regulations/
01:18 PM fragalot: why couldn't they make it work with a wind-up clockwork rather than shut down?
01:18 PM gregcnc_: who wants to wind their luggage?
01:18 PM fragalot: :P
01:18 PM fragalot: it winds itself as you scoot it along on the wheels
01:18 PM fragalot: or each time you pull up / insert the handle bar
01:18 PM gregcnc_: you have a kickstarter worthy idea
01:19 PM fragalot: Thank you. I'll get right on that
01:19 PM gloops: make some pyrethrum spray phipli, organic
01:20 PM phipli: gloops, or just attach a chicken to my handlebars
01:22 PM adamj12b: does anyone know how how I can assign a physical button to clear errors on screen? for example clear a following error
01:23 PM gloops: shouldnt be getting errors adamj12b
01:23 PM fragalot: adamj12b: http://www.linuxcnc.org/docs/html/man/man1/halui.1.html
01:24 PM fragalot: adamj12b: or if you use axis, see section 11.9 http://linuxcnc.org/docs/html/gui/axis.html
01:25 PM adamj12b: fragalot: I am currently using axis but am moving to gmoccapy once my new console is built
01:26 PM fragalot: http://www.linuxcnc.org/docs/html/gui/gmoccapy.html section 5.7
01:27 PM gloops: greenfly plague on Look North lol
01:28 PM adamj12b: fragalot: Thank you. This is exactly what I was looking for.
01:29 PM fragalot: :-)
01:29 PM gloops: interesting, the last time we have a greenfly explosion like this was 1976...notable summer
01:58 PM gloops: need a UK supplier of something like Extira, at the same price as plywood
02:03 PM JT-Shop: lol PayPal just had me fill out a customer dissatisfaction survey on the dispute
02:08 PM phaxx: they never seem to put "go fuck yourselves with a rusty bar" into those drop-down menus, it's really disappointing.
02:09 PM Tom_L: JT-Shop, gettin rain yet?
02:12 PM miss0r: Heh, starting this shop up 5 years ago, I would never have imagined I would produce enough chips in here for me to actualy using a shovel to removing them from time to time. lol
02:13 PM JT-Shop: Tom_L: no, dry as a popcorn fart
02:15 PM * JT-Shop goes to hang the TV on the wall
02:19 PM JT-Shop: looks like a tiny bit to the east of me
03:05 PM CaptHindsight: http://www.automation-overstock.com/categories.asp?cat=9

03:07 PM CaptHindsight: gregcnc_: ^^ local
03:07 PM gloops: i hate meeces to pieces...not really though
03:07 PM XXCoder: CaptHindsight: I understand grinded ballscrews is very accurate, but whats "rolled" ballscrews?
03:07 PM XXCoder: what is its creation process
03:08 PM gregcnc_: rolled just like threads are rolled
03:08 PM CaptHindsight: 2 seconds at the Google finds https://www.youtube.com/watch?v=5-25X1a1nzY
03:09 PM CaptHindsight: Profiroll Ball Screw Rolling
03:09 PM XXCoder: interesting
03:09 PM XXCoder: almost like kurling
03:09 PM CaptHindsight: https://www.youtube.com/watch?v=rwArBBcUNr4
03:09 PM gregcnc_: where are they?
03:09 PM CaptHindsight: Thread Rolling Process
03:10 PM XXCoder: does it just literally push metal in or somehow cuts em?
03:10 PM CaptHindsight: no cut
03:10 PM gregcnc_: plastic deformation
03:10 PM CaptHindsight: push
03:10 PM XXCoder: interesting
03:10 PM CaptHindsight: roll
03:11 PM XXCoder: your second video link is nice
03:13 PM XXCoder: I guess rolled is stronger but maybe slightly less accurate?
03:16 PM gloops: i had some big rolled ballscrews on a garage door opener, stupidly threw them out
03:16 PM XXCoder: dang thats fancy
03:16 PM XXCoder: most is chain based
03:18 PM gloops: im sure the nuts were plastic
03:19 PM XXCoder: yeah but still fancier than average lol
03:21 PM gloops: chain is probably more accurate lol
03:26 PM gregcnc_: my next garage door opener will be linuxcnc
03:26 PM XXCoder: fancy
03:26 PM XXCoder: I wonder if some system like rspi or chip can control such a system
03:26 PM gregcnc_: you know i want that door to stop one the micron
03:29 PM gloops: im bricking mine up, car cant even fit in it anyway
03:29 PM gregcnc_: you'll need a strong motor to lift a brick door
03:29 PM XXCoder: defy expections. lower the door not rise
03:29 PM gloops: not with counterweights
03:30 PM gloops: have you got it going yet lcvette?
03:31 PM gloops: im making some progress with materials, foamex and vinyl wrap is excellent
03:31 PM lcvette: ive been making parts for my home limit switches
03:31 PM gloops: foam/composites are the way to go for quality traditional items
03:32 PM lcvette: have the x axis completed now, working on the Y axis, but im going to take a break from that because all my computer stuff came in!
03:34 PM lcvette: i was wondering before i go and load the Preempt stretch version again if that is the recommended version for the hardware i am now going to be running?
03:36 PM gloops: im sure they said rtai
03:37 PM lcvette: cant im running 7i92
03:37 PM lcvette: need the preempt rt kernel
03:38 PM lcvette: just been seeing some of the other gents in here running different versions of the preempt kernel than the one i had
04:59 PM Deejay: gn8
07:42 PM gregcnc_: hand programming cylindrical interpolation for Fanuc C axis is some effort, but it worked
08:07 PM Tom_L: nice
08:52 PM enleth: so I started watching the NYC CNC watch factory tour that begins with the Makino wire EDM
08:53 PM enleth: looks like a very nice machine, probably quite expensive
08:53 PM enleth: made in Japan, or at least by a Japanese company
08:53 PM enleth: but with all the millions upon millions they put into design and manufacturing, they couldn't even get the fucking labels worded in proper English
08:54 PM tiwake: heh
08:54 PM enleth: "abnormal discharge happens if machining start without locking energizing plate", "energizing plate and base will be damage if contact is not kept"
08:55 PM enleth: that's just one label
08:56 PM enleth: when I see stuff like this, I always start wondering, "if they didn't care here, in a very visible place, where it was EXTREMELY simple and cheap to get it right in compared to the whole work and effort that went into this... where else did they decide they don't care too?"
09:03 PM enleth: obviously this is just anegdotal evidence, but when I used to apply this thinking to software, back when I worked as a technology architect for payment systems and one of my responsibilities was vetting stuff delivered by external contractors before it was allowed to be deployed, I've seen some very hard correlation between completely harmless but highly visible instances of not giving two shits about
09:03 PM enleth: details like proper wording and grammar, proper naming of entities, etc., and very serious but non-obvious problems hidden deep in the code
09:03 PM enleth: I wonder if the same holds for machinery
09:07 PM phaxx: that's basically my experience from the software world too, also curious if it holds in other engineering disciplines. I find it hard to believe that it wouldn't hold.
