01:31 AM Deejay: moin
02:15 AM Loetmichel: mornin'
03:29 AM Loetmichel: hehe, works every time... *SNEEEEZE* ... phone call from the office above: "Gesundheit!" (bless you)... i think i should sneeze a bit less loud ;)
03:37 AM randy: morning
03:51 AM CaptHindsight[m]: Loetmichel: "Gesundheit!" from many thousands of km away
03:51 AM CaptHindsight[m]: that was you?
03:51 AM XXCoder: if that really happened, him and most people around first 1 KM would be dead
03:52 AM CaptHindsight[m]: is anyone really alive?
03:53 AM Loetmichel: XXCoder: well, the cowroker heard it through a 30cm++ concrete ceiling, a few closed doors and a staircase...
03:53 AM Loetmichel: so its not THAT off the mark ;)
03:54 AM XXCoder: lol
06:09 AM JT-Cave: mornng
07:07 AM unterhaus_: JT got the wire, thanks
07:59 AM JT-Cave: cool
08:05 AM simonious is now known as Simonious
08:07 AM perry_j1987: morning
08:08 AM Simonious: good morning
09:50 AM JT-Shop: wonderful dreamhost is screwed up and I can't access my stores...
10:04 AM perry_j1987: is this another "wix" commercial? :P
10:15 AM unterhaus: from the you can cnc anything file, fret dressing cnc machine. $250k https://plek.com/
10:15 AM unterhaus: ^guitar frets
10:18 AM roycroft: that may actually be a very good use of cnc
10:19 AM roycroft: it takes a lot of skill and patience to slot, install, and dress frets
10:20 AM unterhaus: obviously a guitar factory or big guitar dealer needs one
10:20 AM unterhaus: sweetwater does it to their guitars
10:21 AM unterhaus: don't know how the average guitar repairman is ever going to pay for it
10:31 AM roycroft: hmm, i just measured the ball screw that came with my linear rails
10:31 AM roycroft: it's exactly 400mm long, including the shaft ends
10:31 AM roycroft: exactly the same length as the rails
10:32 AM roycroft: i thought that might be the case, but it makes mounting it a bit more tricky
10:35 AM unterhaus: Roy, where did you get your ballscrew
10:44 AM roycroft: from teh auction site
10:45 AM roycroft: i don't have full travel on the rails, either, of course, so this is not restricting movement
10:45 AM roycroft: it just makes mounting the ball screw a bit different
11:23 AM roycroft: https://www.amazon.com/ULTECHNOVO-Printer-Synchronous-Reduction-Supplies/dp/B08P7864CL
11:23 AM roycroft: how is someone supposed to buy that?
11:23 AM roycroft: gear ratio? bore diameters? belt pitch and length?
11:25 AM roycroft: it does say it's shiny
11:25 AM roycroft: and that's all that matters, i suppose
11:28 AM unterhaus: probably 20 and 60 teeth, just like the ones they were copied from.
11:29 AM unterhaus: 5mm bore. Maybe
11:47 AM roycroft: i was not shopping for a gear set - it just popped up on another search i was doing
11:48 AM roycroft: but when i saw it i did wonder who would ever buy something like that with no specficiations listed
11:49 AM roycroft: but as you suggest, there may be some assumed underlying context there
11:58 AM roycroft: well there goes my tool budget for a bit
11:59 AM roycroft: the sander i've been watching for on festoolrecon.com for over 3 years finally just popped up
11:59 AM roycroft: and i was able to get it before anyone else
11:59 AM roycroft: the good news is that there is only one more sander on my list, and then i'm done buying sanders, and that last one is optional
12:07 PM unterhaus: I just got a dewalt cordless sander. Not having a cord is nice, not sure what to think about the sander yet though
12:08 PM CloudEvil: Is it coarse, rough and irritating?
12:08 PM roycroft: the one i just got is the beast that i've wanted for years
12:08 PM roycroft: a rotex 150
12:09 PM unterhaus: sanding is a necessary evil at best
12:11 PM roycroft: i don't enjoy it
12:11 PM roycroft: but that's why i'm willing to invest a lot of money in sanding machines - to make it as fast and painless as possible
12:12 PM JoseIgnacioRome4: Im trying to order some boards from mesaus but im getting a database error
12:12 PM Tom_L: JoseIgnacioRome4, he is having trouble with his host right now
12:12 PM Tom_L: check with him here for updates
12:13 PM JoseIgnacioRome4: Who was it?
12:13 PM Tom_L: JT-Shop, JT-Cave
12:13 PM JoseIgnacioRome4: Oh yea
12:14 PM JoseIgnacioRome4: Damn that sucks i just got to read the scroll back
12:24 PM JT-Cave: yo
12:25 PM JT-Cave: yeah working on it dreamhost changed something
12:42 PM unterhaus: How are things in Rome?
12:49 PM roycroft: very italian, i should think
12:50 PM roycroft: or as my father, in his horrible midwestern accent would say, "eyetalian"
12:56 PM JT-Shop: finally got a live chat at dreamhost
01:02 PM JoseIgnacioRome4: Ohh seems to be back
01:03 PM JT-Shop: yeah they upgraded the server and it changed the ip I needed to use!
01:05 PM * JT-Shop has to go back to Revere... lots of parts to make for them
03:04 PM roycroft: i am so tired of spam/scam calls from "the national center for medicare"
03:05 PM roycroft: they are the rudest people on the planet, other than maga maniacs
03:05 PM XXCoder: geez
03:05 PM roycroft: i politely ask them to not call during business hours and they start lecturning me that i have to listen to them because what they have to tell me is more important than anything else
03:05 PM XXCoder: I wonder if some of MANY calls I get on my phone is that scam
03:05 PM roycroft: i've gotten a dozen or so of those calls lately
03:05 PM XXCoder: well too bad im not answering anytime soon
03:05 PM roycroft: i think i'll stop being polite
03:06 PM roycroft: i still get a lot of calls from the "department of visa and mastercard"
03:06 PM XXCoder: now that I have live captions I probably can answer calls see if anything, and just scream if its scam crap
03:06 PM XXCoder: or make all kinds of weird noises
03:07 PM roycroft: about 95% of all phone calls i get are scammers
03:07 PM XXCoder: 100% for me lol
03:07 PM roycroft: and people wonder why i dislike telephony
03:10 PM unterhaus: if you answer then you get more calls
03:10 PM unterhaus: hard to believe
03:10 PM XXCoder: unterhaus: doesnt always work
03:10 PM XXCoder: I get bunch of calls daily
03:11 PM XXCoder: I never answer, and I never gave number to anyone
03:11 PM roycroft: i primarily need to act according to my new rule all the time instead of some of the time
03:11 PM roycroft: the rule is: after i say "hello", i wait 1.5 seconds
03:11 PM roycroft: if there's no response, i hang up
03:12 PM Tom_L: i don't generally wait that long
03:12 PM roycroft: that takes care of most of the scam calls that are initiated by an autodialler and then auto routed
03:12 PM roycroft: you must not be friends with many spacey hippie types :)
03:13 PM Tom_L: maybe a couple
03:13 PM roycroft: this one a few minutes ago took 2-3 seconds to connect to the scammer
03:13 PM roycroft: so i broke my rule
03:13 PM roycroft: i think i'll start being most strict on that
03:14 PM Tom_L: on a rare moment, i'll feed them what they want for as long as they want right up until they want personal information then i tell them they are scamming me
03:14 PM Tom_L: that's only if i'm very bored
03:15 PM Tom_L: and i throw in a few questions i'm sure they can't answer
03:16 PM roycroft: like "what is the airspeed velocity of an unladen swallow?"
03:16 PM unterhaus: one of the last scammers I talked to started talking to himself
03:18 PM unterhaus: but if you really want to drive them nuts, sign up for jolly roger and have one of their bots do the work
03:18 PM unterhaus: "hold on, there's a fly in the room"
03:21 PM roycroft: i think i need to generate a white list of acceptable phone numbers, and let those ring directly to me
03:21 PM unterhaus: our house has been so peaceful ever since at&t shipped us a device that can't talk to one of their towers
03:22 PM roycroft: the rest i'd route to an auto-attendant that announces "we're happy to talk to any and all solicitors. the rate for our time is $125/hour, and there is a 30 minute minimum. if you wish to be connected to a live person, please have your credit card ready and press '1' now."
03:22 PM unterhaus: they would just give you your own card number
03:23 PM roycroft: if they did i would know
03:23 PM unterhaus: I got the cables through the lathe again, but it's being stubborn. Haven't gotten enough out to be useful
03:24 PM unterhaus: had to take a break
03:25 PM Tom_L: well we're happy to entertain you
03:26 PM roycroft: and we only charge $125/hour to do so
03:32 PM XXCoder: cheap!
03:38 PM perry_j1987_: oh man
03:38 PM perry_j1987_: just had explosion in the shop
03:38 PM perry_j1987_: flipped on the lathe and POP from the VFD
03:56 PM roycroft: uh oh
03:56 PM roycroft: you have a loose/shorted wire between the vfd and your motor, i would wager
03:56 PM roycroft: or the motor is bad
03:57 PM JT-Shop: so recently we upgraded to MySQL 8, during this upgrade the IP to access may have been changed wtf
03:59 PM roycroft: huh?
03:59 PM roycroft: first of all, why is anyone in the universe still using mysql?
03:59 PM roycroft: all the sane people moved to mariadb a long time ago :)
04:00 PM roycroft: second, wtf does upgrading the database engine code base have to do with networking?
04:00 PM roycroft: my.cnf should still be my.cnf
04:00 PM JT-Shop: beats me
04:02 PM JT-Shop: I guess I'm not sane...
04:03 PM roycroft: really, mariadb works so much better than mysql
04:03 PM roycroft: it's way faster, less buggy, and 100% compatible
04:04 PM roycroft: and it does not have a soracle license strung around its neck
04:05 PM JT-Shop: don't think I had a choice...
04:08 PM perry_j1987_: the vfd screen didnt come on and followed by loud pop
04:08 PM perry_j1987_: taking it out of the machine now but cant find a flat screwdriver to loosen the wires to the motor
04:08 PM perry_j1987_: they are REALY cinched down heh
04:15 PM roycroft: sure you do
04:15 PM roycroft: choose to use not dreamhost if that's all they offer :)
04:16 PM _unreal_: I'm trying to decide if I want to buy an ER16 1.5kw spindle or if its even worth bothering
04:16 PM _unreal_: thoughts?
04:16 PM roycroft: i like the er20 2.2kw spindles
04:16 PM _unreal_: that is beyond the means of my new builds specs
04:17 PM roycroft: but if you're just doing really light cuts, the 1.5kw spindle may work
04:17 PM _unreal_: my current tiny cnc machine has a 300watt spindle
04:17 PM _unreal_: I do aluminum and liter materials
04:18 PM _unreal_: the new machine build is going to be 2x more rigid fingers crossed
04:19 PM _unreal_: my X back plane will be 2 4080 C channels stacked
04:19 PM _unreal_: so VERY rigid
04:19 PM roycroft: if you're using small cutters that may work ok
04:20 PM _unreal_: that extrusion will be about 28" long/wide
04:20 PM perry_j1987_: main thing i liked is the water cooled instead of aircooled in my 2.2kw
04:20 PM _unreal_: and I'm trying to decide between SBR rail and the square rail
04:21 PM _unreal_: for the X
04:21 PM _unreal_: if I get the SBR that will add a lot of STIFFNESS to the X as well
04:21 PM roycroft: watercooled means you don't have stray fans moving things around where you want to control airflow for chip clearing and extraction
04:21 PM _unreal_: yes thats part of why I'm getting the new spindle
04:21 PM _unreal_: I already have an ER11 1.5kw
04:22 PM _unreal_: but for my HOME machine I'm toying with if its worth paying a bit extra for the ER16
04:22 PM perry_j1987_: its real nice with er20
04:22 PM _unreal_: I'm not going bigger then ER16
04:22 PM _unreal_: no need
04:22 PM _unreal_: because I dont need a 2.2kw spindle
04:26 PM _unreal_: er16 goes upto a 3/8 shank, ER20 goes upto 1/2" I dont need 1/2"
04:26 PM _unreal_: no reason for me to ever run that large of a bit. not on a 25x25" work area
04:27 PM _unreal_: I'd need like 1000 oz/in steppers or equal servos
04:27 PM _unreal_: again not reasonable
04:27 PM perry_j1987_: edge finder i have is over 3/8 shank
04:27 PM perry_j1987_: it just limits your tool selection
04:28 PM _unreal_: as much as I hate to admit it. this machine will be sitting in my room, till I escape this house
04:28 PM perry_j1987_: i got a job that i have to have a 1/2 bevel tool to have long enough flutes for a single finish pass etc
04:29 PM _unreal_: and this new machine build is only a little larger then the footprint of my current machine
04:29 PM _unreal_: my current machine has a tooling area of 7.75x12.75"
04:29 PM _unreal_: but the rest of the machine BASE extends out housing the PSU's, controllers etc.....
04:30 PM _unreal_: the current machine will transistion into a lite etchings machine for PCBs, and labling signs etc.....
04:30 PM _unreal_: GOD if my stocks would ever recover I'd have the cash to escape :9
04:30 PM _unreal_: :(
04:32 PM t4nk_freenode: hehe... forget it, _unreal_, you've been had.
04:32 PM t4nk_freenode: that's what it's all about
04:32 PM _unreal_: hell last year if the company I work for has not fucked me up so bad at work on my stocks. found out they did it intentionally. fucking up my breaks etc.... JUST to fuck me up. one of my stocks I sold for $109 profit, has I held it 5 more months I'd have made around $200k +/- $30k
04:33 PM _unreal_: god... I'd have been SOOOOOOOO out of this house
04:34 PM t4nk_freenode: lol... that may still come :))
04:34 PM _unreal_: IF they legalize POT in the USA I'm a millionair with one of my stocks
04:36 PM _unreal_: when I get my taxes done if the price is still as low as it is right now I'll add an other 10k-20k shares. even if it ran to close to $4 again I'd make what? $100k ish right now
04:36 PM _unreal_: democrats are KILLLLLLLLLING the usa stock market
04:36 PM t4nk_freenode: hehe.. yep, that's the way to go.. throw more money at it :))
04:37 PM t4nk_freenode: I'm gonna go put something down the toilet myself, BBL!
04:38 PM _unreal_: well thats some money wasted
04:39 PM t4nk_freenode: look man... in a couple of months.. you'll be making coasters professionally all day long, and making trillions of $$$$$
04:39 PM t4nk_freenode: when your machine is done
04:43 PM t4nk_freenode: I can see the headlines already 'Florida male uses brushless DC servo motors to revolutionize coasters: they are now 23% more round'
04:43 PM _unreal_: ugh
04:44 PM _unreal_: I'm trying to find a 110v 1.5kw ER16 SPINDLE aliexpress amazon etc.... can not seem to find one
04:45 PM _unreal_: I have an er11 that fits everything already picked out
04:45 PM _unreal_: but if anyone knows of one I'm still trying to find one that matches the specs i'm lookgin for
04:46 PM roycroft: https://www.amazon.com/Huanyang-Spindle-Milling-24000RPM-Carving/dp/B07LG233LM
04:46 PM roycroft: that is the one to purchase
04:47 PM roycroft: and get the 4 bearing one, not the 3 bearing one
04:47 PM roycroft: oh, wait
04:47 PM _unreal_: thats a 2.2kw I will not go over 1.5k
04:47 PM roycroft: the 4 bearing one is only available in 2.2kw
04:47 PM _unreal_: most of the 1.5kw have 4 bearings as well
04:47 PM roycroft: so i guess you have to get the 3 bearing model if you want 1.5kw max
04:48 PM roycroft: oddly, there's an 800w 4 bearing huanyang, but not a 1.5kw bearing one from them
04:49 PM roycroft: their 800w 4 bearing spindle is water-cooled, but it's er11, not er16
04:49 PM _unreal_: damn every 1.6kw ER16 spindle kit I've found they are out of the 110v version
04:49 PM FinboySlick: Mine has an ER11 spindle similiar to this. Having to fiddle with collets during tool changes is probably one of the first things I'd change.
04:49 PM roycroft: i would have no use for that
04:49 PM roycroft: because i use 12.7mm tooling all the time
04:51 PM FinboySlick: Just thought I would mention in case it could be a factor. I'm actually considering a spindle change just because of it.
04:51 PM roycroft: finboyslick: i've been looking for something that would let me use the tormach tool system with an er spindle, but i've come up with nothing
04:52 PM roycroft: nobody in the cnc router world seems to use tts
04:52 PM roycroft: for what i'll be doing, at least at first, i don't think it will be a big deal
04:52 PM roycroft: i'll probably use a single tool for most jobs
04:57 PM jdh: takes up too much Z. most routers don't have much z anyway
04:58 PM roycroft: i'm designing the router myself
04:59 PM roycroft: and i can raise the z to accomodate it if necessary
04:59 PM roycroft: at the risk of less rigidity
04:59 PM roycroft: but yes, for folks buying off-the-shelf, that could be a problem
05:00 PM roycroft: unless manufacturers start adding it themselves
05:00 PM roycroft: i don't care if it's tormach
05:00 PM roycroft: but some kind of indexible tool holding system would be really nice for cnc routers
05:01 PM jdh: you could make your own. tts is a 3/4" shaft
05:04 PM roycroft: i'll look into it more in a bit
05:05 PM _unreal_: wow I cant not even find a spindle motor its self
05:05 PM roycroft: when i get off work today i'll be working on making my z axis go up and down
05:05 PM _unreal_: 1.5kw er16 110v
05:05 PM _unreal_: every place I look is out
05:05 PM _unreal_: tons of ER11's
05:05 PM _unreal_: AND PLENTY OF er16 1.5kw 220V
05:05 PM _unreal_: I cant use 220
05:06 PM roycroft: well i gave you a like for one
05:06 PM _unreal_: ?
05:07 PM roycroft: it's 3 bearing, but it meets all your other requirements
05:07 PM roycroft: https://www.amazon.com/Huanyang-Spindle-Milling-24000RPM-Carving/dp/B07LG233LM
05:08 PM _unreal_: those are er11's not er16's
05:08 PM roycroft: oh, sorry
05:08 PM _unreal_: and the 2.2kw is er20... too big
05:08 PM _unreal_: for my needs
05:09 PM roycroft: it's actually the same size
05:09 PM roycroft: but it does require more power
05:09 PM _unreal_: the one I'm looking for is all over aliexpress but they are OUT
05:09 PM _unreal_: out of stock
05:10 PM _unreal_: plenty of air cooled er16 110v 1.5kw spindles as well, but I want water cooled
05:18 PM _unreal_: WHOLY crap I found ONE spindle that is an ER16 1.5KW 110v on ebay just the spindle
05:19 PM _unreal_: now I'm wondering is it worth it to get the er16 at $225 JUST for the spindle, and still need the mount, the VFD, collets ETC.... or go with the er11 kit for the same price with lots of bells and whistles?
05:20 PM roycroft: you don't have a vfd for it yet?
05:22 PM Rab: Man, McMaster-Carr's site is broken in the latest Firefox update.
05:22 PM _unreal_: palm to face
05:22 PM roycroft: oh, never mind
05:22 PM roycroft: all the bundles with those specs seem to be air-cooled
05:22 PM Rab: 403 - Forbidden: Access is denied.
05:22 PM Rab: You do not have permission to view this directory or page using the credentials that you supplied.
05:22 PM _unreal_: roycroft, I can not find a KIT with VFD, AND MOUNT AND EVERYTHING with the 1.5kw 110v er16 setup
05:23 PM Rab: Works fine in Chromium, obv.
05:23 PM roycroft: nothing works "fine" in chromium
05:23 PM roycroft: because when you run chrome you're handing your life over to google
05:23 PM _unreal_: now saddly I just found a 2.2kw kit on alexpress with EVERYTHING and freeshipping to the USA for $212
05:23 PM Rab: Updating Google on your every move works fine!
05:24 PM _unreal_: OH never mind
05:24 PM _unreal_: missed clicking something
05:24 PM _unreal_: shipping from USA $315
05:27 PM _unreal_: hum just found a 2.2kw with everything for $294 I dont need the bigger setup but if the price matches what the 1.5kw kit I'm wanting is then fuck it I"ll get the bigger one :(
05:27 PM _unreal_: dont want the extra weight though
05:32 PM Rab: Yeah, I have a 2.2kw spindle and it's not light.
05:34 PM Rab: I changed my Firefox useragent to Chrome and mcmaster.com works great.
05:34 PM Rab: Not too cool.
05:37 PM _unreal_: no wonder that kit is so cheap, its an aliexpress "fire sale"
05:39 PM perry_j1987_: go with 2.2
05:39 PM perry_j1987_: and then you will itch to build the next mill even bigger :)
05:39 PM _unreal_: so this kit comes with the VFD, water pump, spindle, spindle mount, 13 collets, a bit of hose maybe enough for SUPPLY
05:39 PM _unreal_: next mill/bigger wont happen till I get out of this MF'ING house
05:40 PM _unreal_: ya I just cant justify it
05:40 PM _unreal_: the really good value kit from amazon
05:42 PM _unreal_: vfd, h2o pump, 14 collets, some v bits, data cable and a few other small bits... from amazon prime for $239.99, or this aliexpress one that is a 2.2kw, with all the same major hardware just no bits or fun small stuff. for $294 I mean $50 more for 2x the machine
05:43 PM _unreal_: thats hard to turn down
05:43 PM _unreal_: I'd rather the 1.5kw for the weight savings
05:43 PM _unreal_: and sourcing from the USA it will be here in a week+
05:47 PM Rab: Might be easier to do a return through Amazon. Those spindles are occasionally bad out of the box.
05:51 PM _unreal_: ok 2.2kw spindle ordered
05:52 PM _unreal_: $314 total
05:52 PM roycroft: if you're going to buy a 2.2 spindle, get a huanyang
05:52 PM roycroft: not a huanyang clone
05:54 PM _unreal_: I'm not worried
05:54 PM _unreal_: it comes with a YL620-A VFD
05:55 PM _unreal_: and the spindle its self IS a haujiang
05:58 PM _unreal_: does anyone know what gauge wire a 2.2kw spinle takes to the motor?
05:58 PM _unreal_: spindle
05:59 PM _unreal_: I'm looking for a bit of 4 conductor shielded
06:01 PM Tom_L: i'd think 16 would be adequate
06:01 PM _unreal_: I'm guessing 16 guage
06:01 PM Tom_L: i got a roll of 18
06:01 PM _unreal_: thats rated for what 13 amps 110
06:02 PM _unreal_: I do wonder what a 2.2kw spindle can handle?
06:03 PM _unreal_: aside from MORE then what my build will be able to handle
06:09 PM roycroft: if you are feeding single phase power to a vfd, you should derate your vfd, and get the next size up
06:09 PM roycroft: so for a 2.2kw spindle you should get a 3kw vfd
06:09 PM _unreal_: LOL
06:09 PM roycroft: if it's 3 phase to 3 phase you don't need to do that
06:09 PM _unreal_: no
06:09 PM _unreal_: LETS RECAP
06:09 PM _unreal_: My new machine bild will NOT be able to push this spindle to its limits
06:10 PM _unreal_: or even close
06:10 PM _unreal_: and I'm talking about the wire going from the spindle to the vfd.
06:10 PM roycroft: what if you crash?
06:10 PM Tom_L: but if you later build one and transfer the spindle you'll be screwed
06:10 PM _unreal_: not wall to vfd
06:10 PM _unreal_: Tom_L, thats a long ways away
06:10 PM roycroft: but it's your blue smoke
06:11 PM roycroft: you can do with it what you will
06:11 PM roycroft: i personally prefer to keep it well-contained and out of sight
06:11 PM Tom_L: you're just boreing
06:11 PM roycroft: yeah, i'm no fun any more
06:12 PM roycroft: i may have a radical rethink of my x axis
06:13 PM roycroft: i'm not sure why i'm thinking about that while i'm working on the z
06:13 PM roycroft: i'll stop
06:13 PM roycroft: one axis at a time :)
06:14 PM _unreal_: roycroft, I told you if your going to design the machine DESIGN from the z first
06:14 PM roycroft: i don't recall your telling me that, but that is what i did, starting in december or november
06:14 PM _unreal_: its in the longs many times
06:14 PM _unreal_: many many times
06:14 PM roycroft: i got to the point where i needed to rough in the rest of the machine before i could start fine tuning the z axis design
06:15 PM roycroft: but i did start with the z
06:15 PM roycroft: some of your ideas i did incorporate into the current iteration
06:16 PM _unreal_: or let me re-fine that. DRAW a place holder for your working DECK, assumed size. then build your spindle at the max height you expect to need it
06:16 PM roycroft: https://roycroft.us/CNC-Router/Full-Assembly-Preliminary-3.jpeg
06:16 PM roycroft: https://roycroft.us/CNC-Router/Full-Assembly-Preliminary-3-Front-View.jpeg
06:16 PM _unreal_: then you can build the the rest of the zx and finally y SETUP
06:16 PM roycroft: note that the spindle mounting plate hangs lower now
06:16 PM roycroft: i'm adding the z axis ball screw now, and i've not posted any pictures of that yet
06:17 PM roycroft: it's time to go timing gear shopping
06:17 PM roycroft: then i can design the motor mount, and finish th3 ez
06:17 PM roycroft: the z
06:17 PM _unreal_: The reason for that FLOW is because you place the most important part that EVERYTHING is based on FIRST
06:18 PM roycroft: i'm not sure why you are continuining to try to convince me to do the thing that i've been doing all along
06:18 PM _unreal_: once you have it placed at the maximum working height you desire from a "working deck" then all of the math offsets for z carriage design, Z frame, X frame designed height become easy
06:18 PM roycroft: but carry on, if you will
06:19 PM _unreal_: palm tof ace, because you said you where building from the table up before and have not corrected so far as I can recall since
06:20 PM roycroft: i've said from day one that i'm designing the z axis first
06:20 PM roycroft: and that after a point i needed to determine how much z travel is needed, and where i would be able to mount it to get the clearance i need, and that i needed to rough in the rest of the machine to determine those things
06:20 PM roycroft: which is what i did
06:21 PM roycroft: then i returned to the z axis to finish it up
06:21 PM _unreal_: now I am torn on what kind of bearings I should go with for the x
06:21 PM perry_j1987_: lme20uuj
06:21 PM roycroft: i am now able to bury the spindle nose in the spoil board and still get the full 150mm clearance above the spoil board that i want
06:21 PM t4nk_freenode: euh... you are doubling up on your linear rails I hope, _unreal_ ?
06:21 PM perry_j1987_: unless your doing sbr rails
06:22 PM roycroft: i can only just bury it
06:22 PM _unreal_: bearing I mean the x rails
06:22 PM roycroft: and i'll have a hard stop to prevent that
06:22 PM _unreal_: perry_j1987_, I'm toying with SBR's
06:22 PM perry_j1987_: sbr or linear rails
06:22 PM perry_j1987_: linear has a shorter stack
06:22 PM perry_j1987_: less lever effect
06:22 PM _unreal_: but if I do SBR's then I would really be smartest to mount one at the TOP and one at the bottom of the extrusion
06:23 PM roycroft: i don't like the height of sb r rails
06:23 PM roycroft: they are cheaper, but they add too much height
06:23 PM _unreal_: roycroft, THAT is my issue
06:23 PM _unreal_: height
06:23 PM roycroft: i want low profile wherever i can get it
06:23 PM _unreal_: My target is 5" of z
06:23 PM roycroft: and mine is 150mm of z
06:24 PM roycroft: so a little more than yours, but similar
06:24 PM roycroft: i got 400mm rails to get that 150mm working height
06:24 PM _unreal_: since I just ordered that 2.2kw :S that throws off my original Z rails I was going to use
06:25 PM roycroft: the 2.2kw spindle is the exact same size as the 1.5kw
06:25 PM roycroft: it may weigh a bit more, but not much more
06:25 PM roycroft: the smaller, 60mm spindles are air-cooled
06:25 PM _unreal_: POWER I should be able to FEED more
06:26 PM _unreal_: but
06:27 PM _unreal_: hum
06:27 PM _unreal_: if I do get everyting solved with the ve7it motor drivers...
06:27 PM _unreal_: and use the brushed servos
06:27 PM _unreal_: hum
06:28 PM _unreal_: I wonder what the OZ/IN value is for that Y motor...
06:28 PM _unreal_: its going to be 30v 100watt so pushing what 3 amps
06:28 PM _unreal_: err no 4.5 amps
06:29 PM _unreal_: makes me wonder if I should consider getting an other one of those scooters to dig out the motor or find one online
06:34 PM perry_j1987_: cant believe this VFD went pOP today
06:34 PM _unreal_: ?
06:34 PM perry_j1987_: on one of my lathes
06:34 PM _unreal_: the pOP heard round the world.
06:34 PM perry_j1987_: turned it on and POP
06:34 PM _unreal_: hum
06:34 PM perry_j1987_: arc marks on the plastic shroud inside near one of the big caps
06:35 PM perry_j1987_: everything looks in order on the boards though so odd
06:35 PM _unreal_: what failed? a trace or a cap
06:35 PM perry_j1987_: traces look ok
06:35 PM perry_j1987_: havnt probed around yet
06:35 PM perry_j1987_: just to see if there were any voltage left on the caps before handling
06:35 PM _unreal_: cap or transistor
06:36 PM perry_j1987_: only thing in the area of the burn mark is one of the caps
06:57 PM CaptHindsight[m]: sacrificial Chinese caps
06:58 PM roycroft: before you replace or repair your vfd i strongly urge you to test your motor to make sure it is still good
06:58 PM roycroft: a faulty motor can blow up a vfd real good
06:59 PM roycroft: it wouldn't be prudent to replace the vfd and have the same thing happen because you haven't fixed the problem
07:00 PM _unreal_: roycroft, he said it blue TURNING it on
07:00 PM _unreal_: blew
07:00 PM _unreal_: I'm not saying your wrong
07:00 PM _unreal_: but if the last time he used it and there were no issues with use....
07:01 PM roycroft: yes, and if the motor failed, or if one of the wires to the motor has shorted/been cut, that would cause the vfd to blow up
07:01 PM roycroft: i'm not saying a vfd cannot blow up on its own
07:01 PM _unreal_: its highly likely a CAP issue or something contaminating the controller. (shorting) like metal filings
07:01 PM roycroft: i'm just saying that a faulty motor or motor wiring is often the cause
07:01 PM roycroft: and it should be investigated to be sure
07:02 PM _unreal_: hay perry_j1987_ after you fix the CAP(s) test your motor ;)
07:02 PM roycroft: it's not hard to check the motor and motor connectionss
07:02 PM roycroft: and doesn't cost as much time as a new vfd costs
07:05 PM perry_j1987_: CaptHindsight[m] its ac tech usa made lol
07:05 PM CaptHindsight[m]: a few thousand years ago they probably would have thought that the VFD died due to a bad omen, juju, curse or a hex placed by a powerful witch or similar
07:06 PM perry_j1987_: all phases 6.7 ohms
07:07 PM CaptHindsight[m]: heat the motor up to 60C or so and see if the resistance changes
07:07 PM _unreal_: failed component. who knows it may still be in fixable condition
07:07 PM CaptHindsight[m]: where was the capacitor made?
07:07 PM perry_j1987_: the VFD was mfg in 2000
07:08 PM _unreal_: CAPS
07:08 PM perry_j1987_: so the caps are in there sideways with a PCB between them and the shroud
07:08 PM CaptHindsight[m]: https://www.arrow.com/en/research-and-events/videos/arrow-tech-trivia-capacitor-plague
07:08 PM perry_j1987_: there's black marks on the inside of the shroud by one of the caps (the one on top)
07:09 PM CaptHindsight[m]: they also just wear out
07:09 PM CaptHindsight[m]: The Capacitor Plague was an event around 2002 thru 2005 involving capacitors produced from about 1999 to 2003.
07:10 PM perry_j1987_: hmm interesting
07:10 PM _unreal_: a lot of really good computers got fucked by that
07:10 PM CaptHindsight[m]: but you got 22 years out of it
07:11 PM CaptHindsight[m]: i call that a win unless the power was on only for a day or two
07:12 PM CaptHindsight[m]: so cold here the o-rings in the fuel rails are leaking
07:12 PM _unreal_: second use ever LOL
07:12 PM CaptHindsight[m]: hope the car doesn't go boom like the Challenger
07:12 PM _unreal_: ya its like 70 here again
07:12 PM perry_j1987_: it would be best to get a new VFD before trying to fix this one
07:13 PM perry_j1987_: so i have a spare kickin around
07:13 PM perry_j1987_: i do see 1998 etched into one of the pcbs
07:13 PM roycroft: it's cold here today too
07:13 PM roycroft: about 5 degrees right now
07:14 PM roycroft: and it might get down below freezing again tonight
07:15 PM * roycroft wonders why he gets medicare spam and debit card for your kids spam at the same time
07:25 PM skunkworks: https://youtu.be/7HtqwcKDlCk
07:31 PM Tom_L: skunkworks, did you get rid of that noise?
07:33 PM skunkworks: i think so... Couple bypass caps
07:33 PM Tom_L: fairly easy fix..
07:34 PM XXCoder: caps to smooth power spikes and dips out?
07:36 PM skunkworks: I also lowered the voltage to +/-5v instead of 12
07:47 PM snaked is now known as snakedGT
09:34 PM Bleepshop: roycroft: It's 0C, snowing and we've got 2 weather fronts colliding on top of us sometime tonight.
09:50 PM roycroft: it's 1 degree here
09:51 PM roycroft: and light cloud cover, so it will likely freeze tonight again
09:55 PM _unreal_: ok huge weight off sholders. just got my license renew done.. 30min online bs
09:55 PM _unreal_: I guess I dont have to get an eye check or anything??
09:55 PM _unreal_: I mean being in my 40's I'm SOOOO old.
10:18 PM Bleepshop: _unreal_: Wait till you hit 50 and they start carding you for beer and cigarettes.
10:23 PM XXCoder: nobody will card me for beer and cigarettes
10:23 PM XXCoder: ever
10:24 PM _unreal_: ?
10:24 PM XXCoder: not when I was 10, not when I was 18, not now, not when i'm 100
11:08 PM Bleepshop: XXCoder: I was buying Marlboros and Jack Daniels at 17 in Rhode Island [21+ state] back in 1981. It helped that I was already sporting a mustache and greying hair.
11:08 PM XXCoder: lol ok
11:09 PM XXCoder: well reason they wont card me is simple
11:09 PM XXCoder: I arent buying em
11:09 PM XXCoder: ;)
11:09 PM Bleepshop: Then I turned 50 and New Mexico decided that EVERY transaction for alcohol or tobacco had to have valid ID 4 days later. LOL
11:09 PM XXCoder: lol
11:10 PM Bleepshop: I smoke, but don't drink. I was popular as the designated driver who could also buy.
11:11 PM XXCoder: when I was growinf up, I saw enough drunk people and at 12 years old? or so I decided I'll never drink
11:31 PM Bleepshop: Pretty much the same here.
11:42 PM XXCoder: yeah nothing like looking at adults completely out of control
11:42 PM XXCoder: smoking well I never saw reason to, till 9 years ago? my lungs got damaged and yeah its no go since then lol
