01:17 AM Crom: took me awhile to figure out how to set things up so I could home the Y axis at 0 past the bottom of the hole
01:48 AM IchGucksLive: moring from germany
01:59 AM IchGucksLive: morning archivist
02:11 AM IchGucksLive: off till later BYE from rainy germany
02:34 AM Deejay: moin
02:54 AM phipli: morning
03:31 AM gonzo__: morning
03:56 AM Loetmichel: mornin'... sometimes i wonder how much more patience our freelance-designer/mechanical engineer has... Boss just came down to the production floor... "that project that Elmar does... i changed [blablabla]"... thats the fifth time now the boss forces the designer to trash everything and start from scratch. I would have called the boss and told him where to put his project about 3 changes ago...
03:56 AM Loetmichel: especially because that project is supposed to be at the customer for 2 weeks now...
04:14 AM gonzo__: he's probably getting paid well
04:16 AM gonzo__: we have the same at my place, it's the contractors who get the shotty jobs, as they know they are not going to be stuck with it for ever
04:29 AM archivist: if customer messes me about too much I walk off
04:47 AM malcom2073: That's one thing I love about doing freelance work, the ability to fire clients
04:54 AM Hawku-fr is now known as Hawku
04:54 AM XXCoder: the arch is alive!
05:41 AM jthornton: morning
05:42 AM XXCoder: yo
11:07 AM Crom: morning
11:16 AM Jymmm: mornin Crom
11:16 AM Crom: going off to put a cleanout in a friends sewer line today
11:17 AM Jymmm: oh joy.... better you than us
11:17 AM Jymmm: Crom: I'm going to guess either iron or clay pipe too?
11:18 AM Jymmm: ...and tree roots too
11:21 AM Jymmm: Crom: Nice of you, but I don't envy you.
11:51 AM pink_vampire: morning
12:25 PM IchGucksLive: hi from germany
12:27 PM pink_vampire: IchGucksLive: hi from NY
12:29 PM IchGucksLive: My aunt has arrived today for a funeral from Westchester county
12:33 PM SpeedEvil: Hopefully not as the central attendee.
12:36 PM IchGucksLive: at 89 it is well a guess
12:37 PM IchGucksLive: but her sister died at 95
12:43 PM roycroft: that's older than the queen!
12:45 PM IchGucksLive: og she is only 85 ive been told from the back
12:45 PM roycroft: that's still older than the queen acts
01:26 PM IchGucksLive: its getting eben better by the latency as i checked that irq is a real issue on wheezy and latency<
01:36 PM IchGucksLive: this asus pc i wars given for free use in education are realy the hell of a mashine
01:36 PM IchGucksLive: and as the hardware info on wiki lcnc saying it can be run with less then 10k
01:37 PM roycroft: although you may find it hard to believe, given how it's pronounced, we spell it "machine" in english :)
01:37 PM IchGucksLive: 4 glxgears are running at 900fps eatch and i got 8k constand
01:37 PM * roycroft has been meaning to point this out for a few years
01:38 PM IchGucksLive: but basetread jumps to 18k when i close a terminal servo keeps below 10k
01:40 PM IchGucksLive: so i go for 25k in the setup and then when rtai delay error accurs i know the students did klick around
01:41 PM IchGucksLive: im off for today GN8 from Germany
01:42 PM roycroft: tell them to stop clicking and start working!
02:01 PM miss0r: Anyone in here from Scandinavia, who wants to own a IBM bladecenter H with three 7870-b3g units(each with two E5530 and 96gb memory) No harddrives. No powersupplies. It is located in Denmark. Should anyone be interrested the shipping fee is on them. I would estimate the block to weigh in at around 60 - 70kg.
02:56 PM Vitran: Is this the sort of logic I need to get a collet to work in the HAL? I have two buttons, two coils, and two lights http://i.imgur.com/fVIcYTB.jpg
02:57 PM Vitran: And I just realized it should be collet status, not spindle status after the flip flop
02:58 PM Vitran: And I realize now the open collet button should not be activated if the spindle is spinning....
02:59 PM cradek: I would use ladder
03:00 PM skunkworks: I second ladder
03:01 PM skunkworks: it is way easier to visualize this type of logic vs strait hal.
03:02 PM cradek: -|conditions for safe opening...|--|open request button|---(S)--
03:02 PM cradek: -|collet|---(open indicator)---
03:02 PM cradek: -|/collet|---(closed indicator)---
03:03 PM cradek: -|conditions for safe closing...|--|close request|---(R)--
03:03 PM cradek: where (S) and (R) are for the "collet" bit of course
03:04 PM Vitran: I have to learn the ladder now then. I was just scratching the surface on HAL.
03:04 PM cradek: sounds like you're doing a nontrivial machine
03:04 PM Vitran: Hardinge superslant
03:04 PM cradek: have a tool turret too?
03:04 PM Vitran: aye, two of them
03:04 PM cradek: ok yeah learn ladder
03:04 PM cradek: no other realistic way
03:05 PM cradek: a dozen things on the machine will be just like this
03:05 PM Vitran: Rob_H has the exact same machine and has retrofitted four of the same machines before. I asked him for code but he hasn't replied to that
03:05 PM cradek: a bunch of complex interlocks, some request to do something, triggers perhaps several states to go through to make it happen
03:06 PM cradek: heh you'll be better off making it work how you want
03:06 PM cradek: unless you have identical hardware and wiring someone else's configs probably aren't very useful
03:07 PM Vitran: It would give me an idea of what I am looking to make, but yes. Different machine
03:07 PM Vitran: He also replaced all the servos, which was how he got his machine
03:08 PM cradek: is the collet a dual-acting air solenoid that takes momentary activation to change state?
03:09 PM cradek: (I don't know the right terminology but do you know what I mean? you electrically push it open or closed by energizing something for a half second, and then it maintains that state)
03:10 PM cradek: I think that's how my hnc works
03:11 PM cradek: if so, then you have rising edge of the collet signal activating a timer that runs the opener, falling edge a different timer that runs the closer. state machines with timers are easy in ladder, tricky in hal.
03:12 PM Vitran: (phone call) I am not sure why it has two solenoids, but yes. It has two solid state relays that are powered to open or close the collet
03:13 PM Vitran: It is a hydraulic chuck.
03:14 PM Vitran: Maybe it has one to open, one to close, and if neither have power the collet stays in its prior state
03:14 PM cradek: right exactly
03:14 PM cradek: so you do need timers
03:14 PM cradek: triggered by rising or falling edge of the signal representing the desired current state
03:15 PM cradek: probably also interlock so motion doesn't continue until the timer runs out
03:22 PM Vitran: If I want an alert, such as an LED that shows me that there is low air pressure, would that be done in HAL? The machine has an auto-break on the X axis that is pneumatically triggered. I don't want to have low pressure apply the break.
03:23 PM Vitran: the LED would be on the screen, not a physical one
03:24 PM Vitran: *to clarify. the break is deactivated by an air cylinder. It is there so that the turret does not fall down when power is removed
03:27 PM LeelooMinai: lol, got some small machine screw set box from China and there are 1.2mm (60 mil) hex nuts inside...
03:28 PM LeelooMinai: Some 1mm screws too
03:54 PM XXCoder: roycroft: Queen probably will die after I die lol
04:01 PM JT-Shop: what's up XXCoder
04:02 PM XXCoder: drank soylent and relaxing before I go to work
04:02 PM JT-Shop: cool
04:03 PM LeelooMinai: /me facepalms at Trump tweets
04:06 PM XXCoder: which one of em?
04:06 PM LeelooMinai: The one about facelift/bleeding - can someone just eject this idiot into space please?
04:08 PM XXCoder: 297 likes, vs 45's 24 likes. poor rated sure
04:08 PM LeelooMinai: He is really starting annoying me:)
04:09 PM XXCoder: starting? lol you have huge tol
04:10 PM LeelooMinai: He put fake TIME magazine covers with himself onto walls of 5 golf places of his...
04:12 PM LeelooMinai: I started to wonder if political parties are not outdated by this point. They clearly do not work.
04:13 PM XXCoder: what is supposed to happen is partities change and new ones come in, so on
04:13 PM XXCoder: usa its broken
04:14 PM LeelooMinai: Someone needs to "invent" something saner - based on internet, focusing on issues, panels of specialists focused on each problem, take money out of this, madness, etc.
04:14 PM XXCoder: gop have completely surrounded itself with bubble of lies and stories and are starting to float away. you see people reaction
04:15 PM LeelooMinai: Ok, but GOP, democrats, etc. - I see no benefit of artificial divisions like that.
04:15 PM XXCoder: huge amount of cities in usa signed paris agreement, ignoring centeral goverment
04:15 PM XXCoder: parties is good if its working
04:15 PM XXCoder: its not.
04:16 PM LeelooMinai: I mean if you take two random people from USa and put them in a room, there's a good chance they will be able to coomunicate, find common interests, etc. But if you seggregate them by some weird democrat/republican categories and start from there, you have much lower chance they will cooperate.
04:18 PM LeelooMinai: XXCoder: Parties are better than even worse ideas, like theocracy, oligarchy, etc., but I don't think they are that good at this point.
04:18 PM XXCoder: usa is becoming authorian type
04:18 PM XXCoder: wheee
04:19 PM roycroft: perhaps the greatest failing of our founding fathers is that they did not anticipate that we would devolve into triball party factionalism
04:19 PM XXCoder: little bit of theoracy in some states. some state recently signed to allow bible classes in schools. not qu'uan or koran or any other books
04:19 PM LeelooMinai: I think it reached a limit for capitalism - went full retard into the absurd land. Like USSR with communism, etc.
04:20 PM XXCoder: LeelooMinai: honestly NEARLY all forms of goverment work, as long as people are well treated and fairly judged. just that some forms of goverment fairly treating people is nearly impossible.
04:20 PM roycroft: the system they designed worked great at first, but when people started splitting up into tribes during our founding fathers' lifetimes things were not so great, and the founding fathers were aghast
04:21 PM XXCoder: for example very good king country booms under leadership. but king's son fucks it all up. easy
04:21 PM XXCoder: election system blocks that better but witness usa
04:21 PM JT-Shop: Oedipus Rex
04:22 PM LeelooMinai: Imo voting should be compulsory. If you don't vote, there's some penalty, like for not filinf taxes etc.
04:22 PM LeelooMinai: But that does not work for people in power, so they made sure it does not happen:/
04:22 PM JT-Shop: you should have to vote to get a cell phone lol
04:22 PM kyle___: it shouldn't be compulsory, but employers shouldn't be allowed to block employees from voting
04:22 PM XXCoder: whats also needed is better zoning. gerrymangering is out of control some areas.
04:22 PM SpeedEvil: LeelooMinai: that doesn't hugely help it when the problem is an uneducated electorate
04:22 PM XXCoder: JT-Shop: that would ramp up voting so fast.
04:23 PM XXCoder: SpeedEvil: also kinda true. hence all that school fund cutting
04:23 PM kyle___: definitely need voter ID laws too
04:23 PM kyle___: yikes
04:23 PM roycroft: election day should be a national holiday
04:23 PM roycroft: that would make it a lot easier for folks to vote
04:23 PM XXCoder: kyle___: not when ID is impossible to get for some groups of people
04:23 PM roycroft: but the republicans are all about voter suppresion, so they're not going to let that happen
04:23 PM XXCoder: roycroft: yes!
04:24 PM LeelooMinai: Well, how about you vote, but you don't know who you vote for. You just go through a list of proposed policies, check which ones you agree with, and they use this...
04:24 PM XXCoder: kyle___: AND yes some GOP areas abuse that in order to exclude poor
04:24 PM roycroft: we need electoral reform, 100% public financing of elections with NO private money allowed, and preference voting
04:24 PM roycroft: that's how we fix our mess
04:25 PM roycroft: by electoral reform i mean fair redistricting and enabling, not suppressing, votes
04:25 PM LeelooMinai: Right, too bad it's not happening... probably ever - it's far too gone by now.
04:25 PM kyle___: really though?
04:25 PM XXCoder: yep roy
04:25 PM kyle___: why can't the poor get IDs?
04:25 PM roycroft: how about the feds start giving money to the states based on how many people actually voted, not on total population?
04:25 PM XXCoder: many factors
04:25 PM roycroft: because republicans don't want them to have ids, kyle___
04:26 PM kyle___: that's ridiculous
04:26 PM roycroft: but it could also lead to your forced removal by the house, should it determine that you are responsible for the messeno it's not
04:26 PM kyle___: I want everyone to have IDs
04:26 PM roycroft: as an example
04:26 PM roycroft: alabama enacted a voter id law
04:26 PM kyle___: this isn't a partisan issue, it's just the integrity of our voting system
04:26 PM XXCoder: kyle___: voting scam is very rare
04:26 PM kyle___: that's what every democrat says
04:26 PM SpeedEvil: kyle___: Because the ID process is often very hard. If you don't have transport, and the place to get IDs is open only when you're in work, which if you leave, you will be fired from, ...
04:26 PM XXCoder: and ironically it tend to be rich that says.
04:26 PM roycroft: and then closed the dmv offices in the 7 counties with the highest african-american population in the state
04:26 PM XXCoder: *does
04:26 PM LeelooMinai: Obviously they know that if everyone voted, they would never win anything.
04:26 PM kyle___: but rhode island is currently trying to explain 189k invalid votes away
04:26 PM roycroft: forcing people to drive sometimes hundreds of miles to get an id
04:27 PM roycroft: i'm not a democrat
04:27 PM roycroft: and it's not just democrats that are saying that
04:27 PM LeelooMinai: "democrats are not even people" :)
04:27 PM kyle___: http://www.providencejournal.com/news/20161025/voter-rolls-off-by-189000-in-ri-journal-analysis-finds
04:27 PM roycroft: republican legislators say that as they pat themselves on the back for passing voer id laws
04:27 PM XXCoder: LeelooMinai: I'm not people, I am a person. ;)
04:27 PM kyle___: voter ID needs to be accompanied with national compulsory ID
04:28 PM roycroft: sure
04:28 PM XXCoder: kyle___: fee required im sure
04:28 PM LeelooMinai: XXCoder: I was just quoting Eric Trump:)
04:28 PM kyle___: fwiw, I'm not a republican
04:28 PM roycroft: because we really want to be the "papers, please!" country
04:28 PM kyle___: and no, there should be no fee, it should be handed out at birth
04:28 PM kyle___: I think voting is the one place where you want "papers, please!"
04:28 PM roycroft: a national id would destroy the very freedom on which this country was founded
04:28 PM roycroft: why, kyle___?
04:29 PM roycroft: there is virtually no voter fraud at all
04:29 PM kyle___: that's just false
04:29 PM kyle___: plainly false
04:29 PM roycroft: and what little there is is mostly perpetrated by republicans
04:29 PM roycroft: no it's not
04:29 PM kyle___: see my link above
04:29 PM XXCoder: kyle___: ypur site is literally unreadable
04:29 PM XXCoder: very light gray on white
04:30 PM kyle___: that's your complaint? lol
04:30 PM XXCoder: yes
04:30 PM kyle___: jesus christ this isn't worth my time
04:30 PM roycroft: there are orders of magnitude more people unjustly disenfranchised by voter id laws than frauds prevented
04:30 PM XXCoder: lol kyle hates disabled I'd guess
04:30 PM LeelooMinai: voter fraud, lol - people are too lazy for things like that
04:30 PM roycroft: another alternative facts person could not take the heat
04:33 PM roycroft: that link that kyle___ posted won't load for me
04:33 PM roycroft: but based on the url, i am going to assume it is discussing problems with voter registration rolls
04:33 PM XXCoder: roycroft: dont bother, its very gray on white, worse case of "white virus" design ever
04:33 PM LeelooMinai: XXCoder: Hmm, I see "normal" colors.
04:33 PM roycroft: and discrepencies in voter registration rolls is not evidence of fraud by any stretch of the imagination
04:34 PM roycroft: i'll agree that the voter rolls should be cleaned up
04:34 PM XXCoder: as long as cleanup is not fraud by itself
04:34 PM roycroft: but just because a dead person is not removed from the rolls does not mean that someone is voting in place of that person
04:34 PM LeelooMinai: XXCoder: Looks like this to me: http://i.imgur.com/N4i93SW.png
04:34 PM XXCoder: couple states is refusing to allow released criminals vote, even though it is legal in their own laws
04:34 PM roycroft: just because someone is registered to vote in multiple states does not mean that person votes more than once
04:35 PM roycroft: unless the person is part of the trump family or in the trump inner circle :)
04:35 PM roycroft: florida requires a convicted felon to have a personal interview by the governor to gain reinstatement of voting rights
04:35 PM LeelooMinai: All of this is just distractions from really serious issues.
04:35 PM roycroft: and then the governor can decide completely arbitrarily
04:36 PM roycroft: aah, that web site finally loaded
04:36 PM roycroft: and yes, it's exactly what i thought it was
04:36 PM XXCoder: doh yime to go to work
04:37 PM XXCoder: laters
04:37 PM roycroft: an article about an issue that should be addressed, but is completely unrelated to voter fraud
04:37 PM cradek: there were a few real cases this time around: https://www.washingtonpost.com/news/the-fix/wp/2016/12/01/0-000002-percent-of-all-the-ballots-cast-in-the-2016-election-were-fraudulent/
04:38 PM JT-Shop: why can't I print a stupid image at 100% the image size?
04:38 PM * LeelooMinai goes to check if that PL adhesive cured
04:38 PM LeelooMinai: It's a scarily strong stuff btw
04:39 PM roycroft: cradek: i've never denied that there is *some* voter fraud
04:39 PM cradek: so much more relevant: https://www.nytimes.com/2016/09/08/opinion/voter-suppression-in-north-carolina.html
04:39 PM roycroft: my argument is that the voter id and polling restrction laws that republicans pass disenfranchises orders of magnitude more legitimate voters than the cases of fraud they prevent
04:40 PM roycroft: and are targeted at suppressing the vote of minorities
04:40 PM cradek: yes that is a fact that's not disputed by any serious person
04:40 PM roycroft: repblicans generally think that wealthy, landed white men should be the ones voting
04:40 PM Deejay: gn8
04:40 PM roycroft: and not anyone else
04:40 PM roycroft: the whole pushback on this is ridiculous
04:41 PM roycroft: republicans are doing terrible things, and they scream tha anyone who calls them on it is "partisan"
04:42 PM roycroft: if a person murders another person and i say the murderer is a bad person, does that make me "partisan"?
04:42 PM roycroft: of course it doesn't
04:42 PM roycroft: and it's no different when it comes to things politicians and political parties do
04:42 PM cradek: the most important thing happening right now is the wisconsin districting case the scotus is hearing
04:42 PM roycroft: yes
04:42 PM roycroft: that's going to be a landmark case
04:42 PM LeelooMinai: Well, when I first started talking to US people on IRC after moving from Poland to Canada, I was surprised how "assholish" they were about people that do not have a lot of money. Now I understand that how a lot of people in USA think - if you are not rich, you are seen as inferior automatically. Was pretty weird for me, since when I was young no one around thought that way.
04:44 PM cradek: LeelooMinai: many american protestants believe the poor are poor because they're immoral
04:44 PM JT-Shop: you must have been on the #reprap channel
04:44 PM * Jymmm lmao
04:44 PM cradek: LeelooMinai: (and that combines with racism in some really unsavory ways)
04:44 PM Jymmm: cradek: thats funny
04:44 PM * roycroft quotes steinbeck again
04:45 PM LeelooMinai: JT-Shop: I would think that reprap people are not very rich:)
04:45 PM roycroft: "the reason socialism never took root in the us is that the poor don't see themselves as an exploited proletariat, but as temporarily embarrassed millionaires"
04:46 PM Loetmichel: maaan, i hate that company. "deutsche telekom AG"... biggest internetprovider in germany, and they are not able to get their radius servers and DSL links up and running... -> http://www.cyrom.org/palbum/main.php?g2_itemId=16721&g2_imageViewsIndex=1 ... letzs see how long that lasts now... the first drop was at 19:06 btw...
04:46 PM roycroft: in modern days we call it "joe the plumber syndrome"
04:46 PM * JT-Shop wanders out to talk to the chickens
04:46 PM roycroft: my tapered mandrel arrived today
04:46 PM Jymmm: JT-Shop: Do they talk back?
04:46 PM LeelooMinai: Right, initially I thought those people were some kind of masohcists.
04:46 PM roycroft: it has lots of little grooves in it
04:47 PM roycroft: so it's been well-used
04:47 PM JT-Shop: Jymmm: sure they don't have a lot of words but can communicate
04:47 PM cradek: JT-Shop: do chickens have about as much personality as dogs?
04:48 PM Jymmm: JT-Shop: haha, nice =)
04:49 PM JT-Shop: I've only had 1 dog so I can't draw a conclusion from my experience I can say each one has different habits and mannerisms
04:49 PM LeelooMinai: And in 5 minutes JT-Shop: "co co... hello, I am a chicken. i finally managed to trap the featherless weird bird into the cage he made. any idea how to use caps using only a beak?"
04:49 PM roycroft: chickens definitely have personalities
04:50 PM roycroft: i would rather have chickens than dogs though
04:50 PM roycroft: chickens give you eggs
04:50 PM roycroft: dogs just give you poop
04:50 PM JT-Shop: chickens it's a double header you get eggs and poop
04:50 PM cradek: that is a big benefit
04:50 PM roycroft: yes
04:51 PM roycroft: and you can use the poop to grow yummy veggies
04:51 PM JT-Shop: my dog was like a child to us and was very smart
04:51 PM LeelooMinai: Chicken don't give people eggs - people steal eggs from chicken:p
04:51 PM * JT-Shop still tries to figure out how to harvest the poop from the run
04:59 PM phipli: JT-Shop : with a hose
04:59 PM LeelooMinai: Buy ana animal that eats chicken poop? :)
05:00 PM phipli: I made a wire tray for the bottom of our run - I remove it when I move the run knock most of it off (for the compost heap) and hose the rest down.
05:00 PM phipli: Lawn grows far too quickly now
05:01 PM roycroft: i know folks who move their chicken runs periodically, so they can easily harvest and compost the droppings
05:01 PM LeelooMinai: Or be a star of the next Hacker News: "Arduino Powered Optical Recognition Chicken Poop Picker Upper"
05:02 PM Vitran: Sounds fowl
05:03 PM cpresser: different requirements
05:03 PM * cpresser ducks. wrong window. sorry
05:04 PM JT-Shop: phipli: dirt floor
05:05 PM phipli: If you leave it too long, it becomes concrete
05:06 PM phipli: Got some new milling tools in the post today
05:06 PM phipli: a face mill and some end mills
05:06 PM phipli: yay tools <dances>
05:06 PM JT-Shop: yea
05:07 PM phipli: heh. When I first got my mill, I didn't have much disposable income, so I basically bought a 10mm end mill and a 3mm end mill...
05:07 PM phipli: and used them for everything
05:07 PM JT-Shop: I got the ESP8266 to get the NPT time and noticed it uses the Time.h library just for time_t which is just a UL
05:08 PM phipli: the new ESP8266 arrived?
05:08 PM phipli: It is nice to get the right tool for the job now
05:09 PM JT-Shop: yea, seems to have more memory I think
05:09 PM JT-Shop: and the example ran right out of the box after adding my SSsomething and password
05:11 PM phipli: SSID
05:11 PM JT-Shop: yea that one lol
05:11 PM phipli: My code is a little more tricky, you have to transfer some file to the flash memory first
05:11 PM phipli: and to set the SSID + Password, you press both limit switches
05:12 PM JT-Shop: I saw how to do that with my examples
05:12 PM phipli: hum. also need either pull ups or downs (will check in a second) on the limit switches)
05:12 PM JT-Shop: neat
05:13 PM phipli: https://esp8266.github.io/Arduino/versions/2.0.0/doc/filesystem.html
05:13 PM phipli: useful page
05:13 PM phipli: I used that to learn how to use the "file system"
05:25 PM JT-Shop: yea I got a paycheck today!
05:26 PM JT-Shop: phipli: so I'm wondering whay I need a RTC for if the wifi checks the time once an hour and updates the internal clock?
05:30 PM phipli: My esp8266 doesn't have an RTC connected
05:31 PM phipli: checks once a day
05:31 PM phipli: and hasn't been even a second out yet
05:36 PM JT-Shop: got my exp8266 up here now
05:44 PM robotustra: hi
05:45 PM robotustra: is there any new linux cnc documentation in russian?
05:46 PM JT-Shop: sorry current documents are in English only
05:47 PM robotustra: does anybody made own cnc lathe?
05:47 PM JT-Shop: sure
05:47 PM Tom_L: http://www.cnc-club.ru/forum/index.php
05:47 PM robotustra: JT-Shop: did you?
05:47 PM Tom_L: you could ask there
05:47 PM CaptHindsight: robotustra: some did some translating into Russian a few years ago and then stopped
05:48 PM robotustra: CaptHindsight: but that documentation in EMC
05:48 PM JT-Shop: I made a cnc plasma cutter and converted a lathe and mill to LinuxCNC
05:48 PM zeeshan: hi
05:48 PM zeeshan: :)
05:48 PM CaptHindsight: robotustra: EMC is the old name for linux CNC
05:48 PM JT-Shop: zeeshan: where have you been in the outback?
05:48 PM zeeshan: busy at work
05:48 PM zeeshan: :{
05:48 PM JT-Shop: I hear you
05:49 PM zeeshan: are you busy too?
05:49 PM zeeshan: its been like 200 mph here the last couple of months
05:49 PM Tom_itx: bad comes in bundles
05:49 PM JT-Shop: yea, not making much headway but busy
05:49 PM robotustra: CaptHindsight: how big is the difference between 2.7.9 linux cnc and EMC2?
05:49 PM Tom_itx: lost my mill hdd and doesn't look promising to recover anything
05:49 PM JT-Shop: I'm in the process of moving a bunch of stuff from partners garage to my shop... my goodness we collected a bunch of shit over the years
05:50 PM CaptHindsight: http://psha.org.ru/ did lots of the Russian translating, he is not as active as he used to be
05:50 PM JT-Shop: he passed away the other day so I'll wait a while to finish cleaning out his garage
05:50 PM zeeshan: why are you moving
05:50 PM CaptHindsight: robotustra: it's very similar
05:50 PM zeeshan: oh man..
05:50 PM zeeshan: sorry to hear that
05:50 PM JT-Shop: he got down with cancer last Sep
05:51 PM robotustra: I'm trying to choose right controller-motor-panel for the future cnc lathe
05:51 PM CaptHindsight: robotustra: some has changed, you can ask here or check the logs for differences
05:52 PM CaptHindsight: controller-motor-panel?
05:52 PM robotustra: I mean I want to do not standard thing
05:52 PM JT-Shop: sounds like your putting the cart ahead of the horse a bit
05:52 PM CaptHindsight: robotustra: what is not standard?
05:53 PM robotustra: no, I already built cncn mill but I don't quite happy with the current controller
05:53 PM JT-Shop: crap I can't find how I setup ardweene for the modemcu esp8266
05:53 PM CaptHindsight: robotustra: is it Linux CNC right now?
05:54 PM robotustra: what I have now is: Win7+Mach3+TB6560+NEMA17
05:54 PM robotustra: I want on my new lathe LinuxCNC+?+?+?
05:55 PM JT-Shop: stepper?
05:55 PM robotustra: where ?+?+? are things to difine to be happy
05:55 PM CaptHindsight: robotustra: you can change to LCNC using a LPT port + BOB to control the TB6560's
05:55 PM robotustra: do you know about clearpath?
05:56 PM robotustra: can LCNC spool to comport?
05:56 PM robotustra: for instance if I make own controller on the base of atmega2560
05:56 PM CaptHindsight: https://www.teknic.com/products/clearpath-brushless-dc-servo-motors/
05:57 PM robotustra: could I send G-code to this controller via usb?
05:57 PM CaptHindsight: robotustra: well LCNC won't run on a atmega2560
05:57 PM robotustra: CaptHindsight: you didn't got what I want
05:57 PM robotustra: I explain
05:57 PM CaptHindsight: robotustra: all you would need is a LPT PCI/e card and a BOB
05:58 PM robotustra: I want 2 bilt stages
05:58 PM robotustra: what is BOB?
05:58 PM LeelooMinai: Band of Brothers
05:58 PM CaptHindsight: ~$10 break out board
05:58 PM robotustra: 1 sec
05:59 PM robotustra: I'll explain my plan ant you are velcom to ruin it
05:59 PM CaptHindsight: ok :)
06:00 PM CaptHindsight: http://wiki.fablabtoscana.it/images/thumb/1/14/Linuxcnc-controller.jpg/500px-Linuxcnc-controller.jpg.png
06:00 PM zeeshan: i've been tryiung to work with nextgencam to make a post processor for our dual spindle lathe machine
06:01 PM zeeshan: it's annoying how the turrett wants to go to home position whenever it changes tools
06:01 PM CaptHindsight: https://i2.wp.com/www.ijohnsen.com/blog/wp-content/uploads/2016/09/bob-banggood-image.png
06:01 PM CaptHindsight: BOB ^^
06:01 PM zeeshan: in conversational, it only goes away from the z=0 work coordinate + maximum tool length + an extra clearance space
06:01 PM CaptHindsight: an example
06:02 PM CaptHindsight: robotustra: https://i2.wp.com/www.ijohnsen.com/blog/wp-content/uploads/2016/09/bob-mj58.png
06:02 PM robotustra: 1st stage: 1) I make a lathe with steppers with loop control or servo on the base of arduino of whatever WITH MANUAL CONTROL using a keyboard. Stage 2: I connect LCNC to this board using USB cable to spool G-codes into the controller board, as 3d printers usuallu does
06:02 PM CaptHindsight: robotustra: LCNC doesn't support control over USB
06:03 PM robotustra: CaptHindsight: that was the question
06:03 PM CaptHindsight: the difference is that LCNC was written by older and wiser people that know that they don't know everything and with room to grow and be flexible
06:04 PM phipli: robotustra: try GRBL
06:04 PM robotustra: it means I have to make an pin by pin input to read from LPT
06:04 PM robotustra: and reply of couse
06:04 PM CaptHindsight: the LPT is all outputs except for limit switches
06:05 PM CaptHindsight: the control loop is all in the PC
06:05 PM robotustra: ok
06:05 PM CaptHindsight: not out remotely on a card on a USB bus
06:05 PM robotustra: does BOB support manual input?
06:06 PM robotustra: I think I can find PC with built in LPT
06:06 PM CaptHindsight: a BOB is a just a brak out board that has isolation between the PC and the IO's
06:06 PM robotustra: ok
06:06 PM CaptHindsight: robotustra: you can buy PCI or PCIe LPT cards for $10
06:06 PM robotustra: CaptHindsight: thanks, I don't really need, I have
06:07 PM robotustra: ok, if BOB does not support - how can I make a manual control of the lathe?
06:07 PM CaptHindsight: GRBL and the repcrap was written by young know-it-alls that didn't see down the road very far
06:07 PM CaptHindsight: you can have LCNC and manual control of a lathe
06:08 PM robotustra: phipli: what is GRBL?
06:08 PM robotustra: CaptHindsight: I don't like control mill from kbd
06:08 PM robotustra: and mouse
06:08 PM CaptHindsight: https://github.com/gnea/grbl
06:09 PM robotustra: for cnc it's more less ok, but for lathe I don't think it will be ok, because I have to put my eyes on the part
06:09 PM robotustra: that's what I don't like in my current cnc mill
06:10 PM robotustra: if I want to do some manual operations the control is not comfortable
06:10 PM CaptHindsight: when people convert manula mills and lathes to CNC they swap to ballscrews
06:10 PM robotustra: and I would like to remove all flywheels from the lathe and control it by button presses
06:10 PM CaptHindsight: and they can choose to leave the cranks on the ends for manual operation
06:11 PM robotustra: I will build mine from the scratch
06:11 PM CaptHindsight: even easier then
06:11 PM robotustra: yes
06:11 PM robotustra: I have an expetience
06:11 PM CaptHindsight: by manual do you mean "turn a crank"?
06:12 PM robotustra: this is my cnc mill https://www.youtube.com/watch?v=BwhQ6ab06e0
06:12 PM CaptHindsight: other options besides keyboard and mouse are, pendant, joystick or game controller
06:13 PM LeelooMinai: Even midi keyboard will work:p
06:13 PM CaptHindsight: https://www.youtube.com/watch?v=8eAo4aijab0 LinuxCNC Game controller pendant
06:13 PM robotustra: that's why I want to make own controller, it can be joystick based
06:14 PM LeelooMinai: robotustra: I found a joystick being a fail for this.
06:14 PM CaptHindsight: https://www.youtube.com/watch?v=Hqrooh92vNY
06:14 PM CaptHindsight: LinuxCNC pendants - VistaCNC, ShuttleXpress, Keypad
06:14 PM LeelooMinai: You risk activating two axis at once by accident
06:14 PM CaptHindsight: other options ^^
06:14 PM robotustra: LeelooMinai: so, then I'll make a custom KBD
06:15 PM LeelooMinai: robotustra: I am just saying - be careful of joystick idea. You want 3 axis anyways - imo proper keyboard switches, mechanical are much better - you can get them cheap from china.
06:15 PM robotustra: LeelooMinai: no, 2 only
06:15 PM CaptHindsight: robotustra: up to you, but LCNC already has a few options
06:16 PM robotustra: CaptHindsight: which HMI is supported in LinuxCNC?
06:16 PM LeelooMinai: robotustra: Well, still - it's not a plane you are pilotin - sometimes you will want to just step once, and with joystick it will be a a PITA.
06:16 PM CaptHindsight: I'm sort of glad nobody did a gestural interface
06:17 PM CaptHindsight: http://www.criticalcommons.org/Members/ironman28/clips/FFminorityReportGesturalinterfaceH264.mov/
06:17 PM robotustra: CaptHindsight: that's what I'm doing ar work :)
06:17 PM CaptHindsight: robotustra: are you from the future?
06:17 PM CaptHindsight: :)
06:17 PM LeelooMinai: Right, and then you scratch your nose and boom - you have a hole in a $1k vise.
06:18 PM robotustra: not yet :)
06:18 PM robotustra: I just did a dataglove
06:18 PM robotustra: and it works
06:18 PM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl take a look at all the GUI's
06:18 PM robotustra: 15+6 DOF
06:18 PM LeelooMinai: lol, perl web page in 2017
06:19 PM robotustra: What about lathe control I'm very conservative
06:19 PM LeelooMinai: robotustra: I would not use that word, ever, again:p
06:19 PM CaptHindsight: https://www.youtube.com/watch?v=PC3N-uadAk0
06:19 PM LeelooMinai: It's tainted by now
06:20 PM LeelooMinai: too bad those rubbery keyboards have terrible tactile feedback.
06:20 PM robotustra: CaptHindsight: hm, this one will be too big for my lathe
06:21 PM robotustra: I got Cherry-Mx keys to build one
06:21 PM CaptHindsight: robotustra: run the lathe simulation on the LiveCD
06:21 PM CaptHindsight: I think it uses AXIS
06:21 PM robotustra: CaptHindsight: no need yet
06:22 PM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Screenshots
06:22 PM robotustra: I'm a real world man, I don't do simulations other than in real physical wold
06:22 PM robotustra: world
06:22 PM CaptHindsight: heh, to see examples
06:23 PM robotustra: why I was asking about manual control besides LCNC is that I don't want to involve computers to lathe something manually
06:23 PM robotustra: envolve*
06:23 PM robotustra: or involve*
06:23 PM CaptHindsight: just turn off LCNC and use the cranks
06:23 PM robotustra: CaptHindsight: NO CRANCS
06:23 PM robotustra: CaptHindsight: NO CRANCSCRANKS*
06:23 PM CaptHindsight: steppers/servos with ballscrews
06:24 PM robotustra: no
06:24 PM robotustra: press buttons
06:24 PM robotustra: for run and jog
06:24 PM CaptHindsight: or use a joypad or similar
06:24 PM robotustra: 21st century, what cranks?
06:24 PM CaptHindsight: yeah or buttons
06:24 PM robotustra: forget about cranks
06:24 PM CaptHindsight: cranks with encoders mounted on skateboards
06:25 PM robotustra: I can't crank as precise as servo does
06:25 PM CaptHindsight: the cutting tool follows the path of the rider
06:25 PM CaptHindsight: or maybe GPS and truck
06:25 PM robotustra: again, READER, not WRITER
06:26 PM robotustra: so, you have answered to the part of my questions, thanks
06:26 PM CaptHindsight: it's a bit lost in translation
06:26 PM CaptHindsight: but close enough
06:26 PM CaptHindsight: my Russian is terrible
06:27 PM robotustra: my inglish too
06:28 PM CaptHindsight: https://www.youtube.com/watch?v=VWDVuDAmUK8 a big trackball could be another fun interface
06:29 PM robotustra: what about touchpanel on the top of the display?
06:30 PM CaptHindsight: take a look at Touchy
06:30 PM CaptHindsight: https://www.youtube.com/watch?v=XGDq6620fPQ
06:30 PM CaptHindsight: http://linuxcnc.org/docs/2.4/html/gui_touchy.html
06:34 PM CaptHindsight: back to work here Прощай
06:34 PM robotustra: it's not good work
06:34 PM robotustra: it's not good word
06:34 PM Tom_itx: CaptHindsight did you find the stepper driver you were looking for?
06:34 PM robotustra: this word means that you say buy buy forever
06:35 PM CaptHindsight: heh
06:35 PM robotustra: right word is Пока
06:35 PM CaptHindsight: hasta
06:35 PM CaptHindsight: Tom_itx: your clock is off
06:35 PM CaptHindsight: Tom_itx: ordered a few to be sure I get one tomorrow
06:35 PM Tom_itx: that's likely not all that's off
06:39 PM robotustra: hm, may be I can put my controller instead of computer+LCNC and connect it to BOB
06:40 PM robotustra: in this cace I'll be able to remove manual and put LCNC
06:40 PM robotustra: case*
06:40 PM robotustra: swap them
06:45 PM robotustra: actually I find out that free hands controls are not very good
06:46 PM robotustra: the hand should be mounted on the control firmly to make small movements precisely
06:48 PM JT-Shop: say goodnight Gracie
06:49 PM robotustra: goodnight Gracie
06:51 PM robotustra: why does BOB has USB connector?
06:52 PM robotustra: have*
06:52 PM CaptHindsight: for power only
06:52 PM robotustra: oh ok
06:58 PM robotustra: BOB has only 1 pin to control spindle?
06:59 PM robotustra: on/off?
06:59 PM robotustra: no rev/fvd?
07:04 PM CaptHindsight: the Chinese images and labels are the most accurate
07:04 PM CaptHindsight: are/are not
07:13 PM CaptHindsight: http://linuxcnc.org/docs/html/examples/spindle.html
07:15 PM CaptHindsight: robotustra: between the old Russian docs and asking here you should be able to build whatever you want
07:18 PM robotustra: who sets the spindle RPM? LCNC or VFD?
07:21 PM robotustra: is it possible to control RPMs on spindle using this VFD from LCNC? http://www.ebay.com/itm/2-2KW-ER20-WATER-COOLED-SPINDLE-MOTOR-AND-2-2KW-VFD-MATCHED-INVERTER-DRIVE/250748327119
07:24 PM robo: Hi all, I'm trying to set "soft limits" on an old leadscrew cncrouterparts table with a geko g540 and nema steppers. I have home and limit switches for each axis. If I set home switch location < min table travel, will that stop travel before limit/home switches?
07:26 PM robotustra: robo: try it
07:27 PM robotustra: robo: nobody can answer your question, you have to try it
07:27 PM robotustra: it should but it mustn's to stop
07:28 PM * robotustra don't have any limit switches on the mill
07:59 PM robotustra: who can tell me why the slides on cnc lathe are tilted at some angle, but not parellel to the ground?
08:00 PM robo: im getting close - is there a way to reload the .ini without restarting linuxcnc?
08:04 PM robotustra: what a nice cnc lathe https://www.youtube.com/watch?v=eipyve8xv24
08:28 PM malcom2073: robotustra: So the saddle doesn't fall on the ground?
08:40 PM robotustra: malcom2073: are you about the angle placement?
08:43 PM robotustra: cute engine https://www.youtube.com/watch?v=lgAgG27_Oj8
08:45 PM SpeedEvil: http://www.f1-2000.co.uk/ I wishhadn't stalled.
08:46 PM malcom2073: robotustra: I'm not sure what your question is asking?
08:46 PM malcom2073: SpeedEvil: I heard rumor he's still slowly working on it, I forget who from though
08:46 PM malcom2073: someone in here
09:26 PM robotustra: cool, I got my answer, VFD can be controlled through RS485 from LCNC https://www.youtube.com/watch?v=1NF8EFoPlrk
10:36 PM cncnoob: Anyone out there using a VFD? I'm looking at some from Automation Technologies and I'm confused about the RPM ranges
10:36 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-spindle/1-5kw-air-cooled-motor-spindle-and-matching-inverter-and-1-5kw-vfd/
10:37 PM cncnoob: That guy is air cooled but claims to have an RPM range of 0 - 24000
10:37 PM LeelooMinai: cncnoob: I have GS2 VFD from auitomationdirect - it's supported by linuxcnc.
10:37 PM cncnoob: What kind of RPM range does it have?
10:38 PM roycroft: that depends on your spindle motor
10:38 PM cncnoob: This other one I'm looking at from Automation Technologies is watercooled and it says it has an RPM range of 6000 -24000
10:38 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-spindle/1-5kw-vfd-spindle-inverter-kl-vfd15-110vac-input-with-1-5kw-water-cooled-spindle/
10:38 PM cncnoob: Both of those VFDs come with a spindle motor, like a package deal
10:40 PM cncnoob: optimally I would like to have a motor that would happily run from 500 to at least 10000 without any gearbox
10:41 PM LeelooMinai: cncnoob: From what I remember I had some doubts about it when setting things up. I think it was mostly because I was expecting the RPM being configured explicitelly, but I had to focus more on the spindle base frequency and then set some multipliers, etc. but in the end I could reach 16k RPM, etc. no problem, just display could not handle more than 4 digits, so it is showing 9999 there, but from the linuxcnc point of view everything
10:41 PM LeelooMinai: now checks.
10:42 PM LeelooMinai: So I guess to summarize: that GS2 drive can handle speeds over 10k RPM fine, even though figuring that out from the specs is not obvious.
10:43 PM cncnoob: With the motors I've been looking at I'm more worried about the low end of the range. 6000 RPM is way to fast for a lot of things, and if that is as slow as those motors I linked to would go I would have to figure something else out (different motor or gearbox).
10:43 PM LeelooMinai: The docs ares pretty good otherwise. Far better than what you can get with Chinese ones.
10:43 PM LeelooMinai: cncnoob: I can run my spindle at 100 RPM with it.
10:45 PM cncnoob: Awesome!
10:45 PM LeelooMinai: cncnoob: Of course with AC spindle + VFD drive one thing is being able to go that low, another is what torque it will have then - but that's kind of orthogonal topic.
10:45 PM cncnoob: Right
10:45 PM cncnoob: This is for a mini mill so I don't need a ton of power
10:46 PM LeelooMinai: In any case, I have tested range 100 to 16kRPM or so with it.
10:46 PM cncnoob: I want the versatility though.
10:46 PM LeelooMinai: It's well build and has reasonable price too.
10:46 PM LeelooMinai: built*
10:47 PM cncnoob: what motor are you running?
10:48 PM LeelooMinai: Chinese 800watt AC spindle.
10:48 PM LeelooMinai: Air cooled.
10:58 PM cncnoob: Is your VFD 110v? How about your motor? Does it look anything like the one shown here?
10:59 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-spindle/1-5kw-air-cooled-motor-spindle-and-matching-inverter-and-1-5kw-vfd/
10:59 PM LeelooMinai: Yes, typical Chinese one. Yes, I got 110V VFD
11:00 PM LeelooMinai: 400Hz base frequency - same
11:00 PM LeelooMinai: But ER11
11:00 PM roycroft: cncnoob: if you're needing a wide range of speeds on a min-mill, you might consider using the stock spindle for low speds, and getting a high speed spindle for when you need the faster speeds
11:01 PM roycroft: also, if you're using an asian import vfd, getting one rated for more power than you need is a good idea
11:01 PM roycroft: if you have a 1.5kw motor, get a 2.2kw vfd for it
11:01 PM roycroft: the vfd will run cooler and last longer
11:03 PM cncnoob: So you would advocate switching out the drives when I need low speed? I guess I could do that. Doesn't seem very convenient though. I think I would be more apt to install a gearbox if I couldn't find a motor that would work from 500 - 10000 RPM
11:03 PM cncnoob: based on what @LeelooMinai is saying it sounds like there are motors out there that have the range I want though
11:04 PM roycroft: if it were me (and it might be, as i'm doing a mini-mill cnc conversion soon), i'd make a fixture for the high speed spindle
11:04 PM roycroft: and mount it when needed
11:04 PM cncnoob: How high of speed are you wanting to get?
11:04 PM roycroft: but i mostly machine steel
11:04 PM roycroft: 1200rpm is fine for 90% of my stuff
11:05 PM roycroft: but i want to be able to do some really fine stuff at times, and would like 20k rpm for that
11:05 PM cncnoob: oh
11:05 PM roycroft: i don't know what your work load will be
11:05 PM cncnoob: I will not be doing steel very often, but when I do it will be thin, like 1/8" or 1/16"
11:05 PM roycroft: and i'm not suggesting that what i need would work for you
11:06 PM roycroft: if you mostly need high speeds, then a single spindle might work for you
11:06 PM cncnoob: yeah I understand, it is good to hear what other more experienced people are doing though
11:06 PM roycroft: be aware that you'll lose most torque if you go really really slow with it
11:07 PM cncnoob: I don't want to spend $$$ then find my setup doesn't hit my target speeds
11:07 PM roycroft: so when you need to machine steel you'll have to take really really light cuts
11:07 PM cncnoob: I'm used to doing that already because all the stuff I've been making is tiny
11:08 PM cncnoob: The largest bit I'm using most of the time right now is a 1/8" end mill
11:08 PM cncnoob: I'll do bigger stuff later I'm sure as my projects change
11:16 PM CaptHindsight: roycroft: http://www.upi.com/Health_News/2017/06/28/Researchers-create-new-probiotic-beer-that-boosts-immunity/2701498662639/
11:20 PM roycroft: that's nothing new
11:20 PM roycroft: if one drinks enough beer one is invincible
11:20 PM roycroft: that has been the case for millennia
11:21 PM cncnoob: hah
11:22 PM cncnoob: @roycroft, are you planning on sticking with the stock holder on your mini mill when you do your motor conversion?
11:22 PM roycroft: i'm planning on using the stock spindle and motor for most work
11:22 PM roycroft: and fabricating a spindle mount for an auxiliary spindle for high speed work
11:23 PM cncnoob: I have an R8 and I would like to keep it, but I think I might need to upgrade my bearings. Not sure if there is any other reason an R8 wouldn't work at speeds over 10K
11:24 PM cncnoob: or if it would even be ok at 10K
11:25 PM LeelooMinai: CaptHindsight: lol @ a heading on that site: "Study: Lack of health insurance can shorten lives"
11:25 PM roycroft: i'm building a wood router table soon, and will use a 2.2kw water-cooled spindle for it with a vfd
11:25 PM roycroft: that will run at speeds from about 8krpm to 22krpm
11:26 PM roycroft: i want to do some cnc engraving, which would require a high speed spindle, but that may not be necessary - i'm about ready to do some etching that may work for me instead of doing engraving
11:27 PM roycroft: so it's very possible that i'll just stick with the stock spindle/motor on my mini-mill indefinitely
11:30 PM CaptHindsight: cncnoob: it depends on how well it is balanced
11:32 PM CaptHindsight: and R8 with a drawbar is kind of clunky
11:35 PM cncnoob: Humm
11:36 PM cncnoob: @CaptHindsight all the spindle motors I'm looking at have an ER holder which would kill my dream of having a power draw bar
11:36 PM CaptHindsight: https://www.tormach.com/uploads/923/TD10368_HSS_Install_0216A_WEB-pdf.html
11:36 PM CaptHindsight: ^^ take a look at what Tormach did for higher speeds
11:36 PM cncnoob: That is why I wanted to keep the R8. That and because I already purchased a bunch of R8 holders :)
11:37 PM cncnoob: yep, ER20
11:37 PM CaptHindsight: some R* holders are speced and balanced for 10k rpm
11:37 PM CaptHindsight: R*/R8
11:40 PM LeelooMinai: Hmm, spindle breaking procedure in that PDF - running 1 hour at increasing speeds
11:40 PM LeelooMinai: Ṅever heared that before.
11:41 PM cncnoob: @LeelooMinai are you running 110V or 220V VFD?
11:41 PM LeelooMinai: cncnoob: 110 - as the machine is in my bed/room

11:41 PM cncnoob: haha
11:42 PM cncnoob: What is the highest frequency of your VFD?
11:42 PM CaptHindsight: http://www.ebay.com/itm/New-3KW-Water-Cooled-Automatic-Tool-Changer-ATC-Spindle-Motor-380V-BT30-for-CNC/222513525604
11:42 PM CaptHindsight: 15k rpm bt30 ATC
11:43 PM roycroft: my vfds max at 400Hz
11:43 PM LeelooMinai: cncnoob: 400Hz
11:43 PM CaptHindsight: cheap China model http://www.ebay.com/itm/CNC-9KW-220-380V-ATC-Spindle-Motor-ISO30-BT30-China-HSD-Spindle-11KW-VFD-1000Hz/122359169694
11:44 PM cncnoob: And your 800w motor is rated to handle 400Hz?
11:44 PM roycroft: http://www.ebay.com/itm/162289056146
11:44 PM roycroft: this is what i'm looking at for my wood router spindle
11:45 PM LeelooMinai: cncnoob: It has 400Hz base frequency, yes
11:45 PM roycroft: i'm looking at a water cooled spindle because on the wood router table the spindle will be inverted
11:45 PM CaptHindsight: keep it cool, hope for a good one
11:45 PM roycroft: and in an environment full of sawdust
11:46 PM roycroft: the water cooled ones are sealed, so they won't fill up with sawdust
11:46 PM cncnoob: good reason to stick with the watercooled
11:46 PM cncnoob: I'm looking at the little brother of that one
11:46 PM CaptHindsight: cool will extend the life of even poor bearings
11:46 PM CaptHindsight: but that won't help with runout
11:46 PM cncnoob: What I don't get is that this one says its RPM range is 0 - 24000 and it is air cooled
11:46 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-spindle/1-5kw-air-cooled-motor-spindle-and-matching-inverter-and-1-5kw-vfd/
11:47 PM cncnoob: but this one says its RPM range is 6000 - 24000
11:47 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-spindle/1-5kw-vfd-spindle-inverter-kl-vfd15-110vac-input-with-1-5kw-water-cooled-spindle/
11:47 PM cncnoob: and it is water cooled
11:47 PM cncnoob: maybe a typo on the first one?
11:48 PM CaptHindsight: cncnoob: careful with the Chinaco parts, it's difficult to find good ones
11:49 PM cncnoob: I've had good luck with the stuff from automation technology so far... for the most part
11:49 PM CaptHindsight: I have an order coming from them tomorrow, their website is not accurate when it says in stock
11:49 PM cncnoob: Yeah, their website needs work for sure
11:49 PM CaptHindsight: I get very few things from them now
11:49 PM CaptHindsight: they are near me
11:49 PM CaptHindsight: too much bad stuff
11:49 PM cncnoob: yeah, same. Only like 2 days and I get it
11:50 PM cncnoob: They sent me the wrong motors once
11:50 PM CaptHindsight: crunchy bearings
11:50 PM cncnoob: but they fixed it
11:50 PM CaptHindsight: bearings with detents
11:50 PM CaptHindsight: routers with mm's of lash
11:50 PM cncnoob: I purchased a probe from them as well, but I wasn't happy with the quality
11:50 PM cncnoob: it works though
11:50 PM cncnoob: that is no good
11:50 PM cncnoob: did you send back?
11:50 PM CaptHindsight: I don't get much from Shars either
11:50 PM CaptHindsight: just too poor quality
11:51 PM CaptHindsight: you end up paying for it with poor results
11:51 PM CaptHindsight: and having to buy better cuttings tools anyway
11:51 PM cncnoob: My whole setup is from china :(
11:51 PM cncnoob: other than the thompson ballscrews
11:51 PM CaptHindsight: cncnoob: I usually pick up in person to be sure I get something I can use
11:51 PM cncnoob: and they make more noise than I would like
11:52 PM CaptHindsight: motors die, drivers die too early
11:52 PM cncnoob: I'm not as close as you I guess so I don't have that luxury
11:52 PM cncnoob: Humm
11:52 PM CaptHindsight: so I mostly avoid them
11:52 PM cncnoob: I don't use my machine every day, so I'm not taxing it a lot
11:53 PM CaptHindsight: i used to think that...
11:53 PM cncnoob: I over sized my drivers and motors for my machine though so it isn't being stressed at all
11:53 PM CaptHindsight: but then you need it for something and it lets you down
11:53 PM cncnoob: Where do you get your stuff now?
11:53 PM CaptHindsight: all over
11:53 PM CaptHindsight: I prefer used vs automation technology
11:54 PM cncnoob: Honestly if it wasn't for the cheap China stuff I wouldn't be able to do any milling
11:54 PM CaptHindsight: Parker, A&B, Yaskawa etc
11:54 PM cncnoob: just to expensive otherwise
11:54 PM CaptHindsight: I have 20 year old parker stuff that just won't die
11:58 PM CaptHindsight: I pulled out some supported rail and bearings from Automation tech I got a couple of years ago
11:58 PM CaptHindsight: I'm using it for a drawer vs any positioning
11:58 PM CaptHindsight: the bearings are noisy
11:59 PM CaptHindsight: and this is 20mm supported rail
11:59 PM CaptHindsight: cheap crap
