12:40 AM gloops: yes you cant beat brass
01:09 AM gloops: wow that is a lot of money for that https://www.ebay.co.uk/itm/Emco-Unimat-3-Lathe-Milling-Machine/332614643169?
01:20 AM SpeedEvil: You can melt anything in a backyard furnace.
01:33 AM gloops: i suppose it depends what you mean by backyard furnace
01:33 AM Deejay: moin
01:34 AM gloops: charcoal fired you can melt brass, for copper up wards you need to be adding air and gas and larger volume of fire etc
01:36 AM * SpeedEvil is seriously pondering a vacuum furnace.
01:38 AM gloops: what does that do?
01:41 AM gloops: im going to make a kind of gingery furnace soon, just for ally, a slightly bigger more robust version disguised as a barbeque
01:42 AM SpeedEvil: gloops: It lets you use very odd insulators and has no issue with oxygen.
01:42 AM gloops: funny how the culture is, its perfectly ok to have a fire for entertainment - fire pit, in fact its very trendy, or for incinerating meat and stuff with the neighbours
01:43 AM gloops: SpeedEvil - i spot a drawback
01:43 AM gloops: youre trying to keep the heat in
01:43 AM gloops: a vacuum sucks it out
01:44 AM SpeedEvil: It doesn't.
01:44 AM SpeedEvil: Vacuum has no temperature.
01:44 AM gloops: wheres the oxygen coming from?
01:45 AM SpeedEvil: Air.
01:45 AM gloops: the vacuum has no temperature, but the air it sucks does
01:46 AM MarcelineVQ: he's not sticking a dyson over a campfire gloops :>
01:46 AM SpeedEvil: A vacuum furnace is a furnace that has essentially complete vacuum inside.
01:46 AM SpeedEvil: There is no convection.
01:46 AM gloops: wheres the fire?
01:46 AM SpeedEvil: Or meaningful heat transfer. Either resistive heat elements, or inductive.
01:46 AM fragalot: mornin'
01:47 AM gloops: well, i think its better to blow air in
01:47 AM gloops: morning fragalot
01:47 AM SpeedEvil: gloops: That's admittedly fun with molten titanium.
01:47 AM SpeedEvil: May not actually cast stuff very well though.
01:47 AM gloops: mine will
01:48 AM fragalot: gloops: a vacuum furnace is technically filled with the ideal insulator
01:48 AM gloops: the neighbours will look out and say oh look hes got his garden chimenea going :)
01:49 AM gloops: instead of 'jesus hes melting metal down the garden!'
01:50 AM MarcelineVQ: making clinkers is nice and all but an electric furnace seems like a lot less hassle
01:50 AM fragalot: MarcelineVQ: they are. :P
01:50 AM MarcelineVQ: I used to propane forge and it was hassle enough, these days I'd want induction
01:50 AM fragalot: just not cheap as an initial invention
01:50 AM fragalot: investment*
01:50 AM gloops: maybe, would be nice, but breaks the number 1 convention of all backyard projects
01:51 AM gloops: it costs money to build, and run
01:51 AM SpeedEvil: First kill the witnesses?
01:51 AM MarcelineVQ: first, agree on a place to meet that you wouldn't normally go to
01:51 AM gloops: charcoal is essentially free
01:51 AM fragalot: 2nd don't talk about fight club?
01:52 AM gloops: there is no point in melting scrap aluminium if the product is more expensive than you could have bought it for
01:52 AM fragalot: the electricity required to melt a small amount of metal isn't /that/ expensive
01:52 AM MarcelineVQ: there might not be a lot of point in the first place if you don't know what the scrap came from
01:53 AM gloops: i made some good plates from mixed scrap
01:53 AM gloops: stiffer id say than the ones i bought
01:53 AM fragalot: with scrap you have to be lucky
01:53 AM MarcelineVQ: aluminum is pretty finnicky, I can't imagine casting it is all that fun, even just having sharpie residue near it causes inclusions
01:53 AM fragalot: some alloys don't mix all that well
01:53 AM gloops: machines beautifully
01:54 AM gloops: in my experiments i found there was an optimum kind of fluidity at which to pour
01:54 AM gloops: ally tends to turn to slush very quickly
01:55 AM gloops: even during a few seconds pouring
01:55 AM MarcelineVQ: yeah, the point between cherry and molten is pretty stark
01:55 AM MarcelineVQ: lot of fun to learn to weld
01:55 AM fragalot: I dislike welding alu :P
01:56 AM MarcelineVQ: it's okay, if you're welding more than one thing, but getting it right first shot is a skilltest for sure
02:03 AM XXCoder: wow
02:03 AM XXCoder: I cant crimp rj45s. I keep getting failed cable test
02:03 AM XXCoder: I wonder if its crap rj45s or me
02:06 AM fragalot: is your tester set right?
02:06 AM fragalot: (eg. straight vs cross)
02:07 AM XXCoder: I would know if it was cross vs stright
02:07 AM fragalot: because even with my "bag of 100" for $1 from china, i've never had one fail straight after crimp
02:07 AM XXCoder: nah its crossed wires, not connected, etc
02:07 AM XXCoder: I dont get it
02:08 AM XXCoder: I very rarely fail and now 5 stright
02:08 AM fragalot: odd :P
02:08 AM XXCoder: indeed
02:08 AM fragalot: anyway, i'm off to make me some mill bits!
02:11 AM XXCoder: wires look very stright and professal style
02:11 AM XXCoder: all reaches end
02:11 AM XXCoder: so dunno seems to me that crimp in bits may have cut iffy
02:11 AM XXCoder: its this type https://www.youtube.com/watch?v=DnKDo0iV9Ec fragalot
02:11 AM XXCoder: heck his is bit more jagged and uneven
02:22 AM XXCoder: https://www.thingiverse.com/search?q=heat&sa=&dwh=305ad2fd66aa311
02:36 AM MrHindsight: https://youtu.be/YbOg_4rrJxc?t=20m41s Atlas V AFSPC-11 Live Launch
02:37 AM XXCoder: nice love to watch launches
02:40 AM MrHindsight: hen asked whether Boeing might launch a car into space, he replied instead that "We might pick up the one that's out there and bring it back."
02:40 AM XXCoder: lol
02:40 AM XXCoder: hey its pretty expensive car after all
03:10 AM XXCoder: hmm
03:10 AM XXCoder: I wonder which tool would tell me which end is badly crimped on ethernet cable
03:12 AM MarcelineVQ: electric fence testers can detect the direction of a short, wonder if that principle could be useful for you
03:12 AM MarcelineVQ: probably not since a bad crimp would be open rather than grounded I suppose
03:12 AM XXCoder: for some reason I am unable to make good cables
03:13 AM XXCoder: I wonder if those rj45 suck or its just me
03:13 AM MarcelineVQ: I've never had good luck with cat cable
03:13 AM XXCoder: before today I always made good cables
03:13 AM XXCoder: but those 3 peice rj45s dunno
03:14 AM XXCoder: and yeah been looking for such tool, cheap
03:14 AM XXCoder: because ethernet version costs so much
03:14 AM XXCoder: hundreds of bucks
03:15 AM IchGucksLive: morning froim germany
03:16 AM XXCoder: hey german guy
03:16 AM IchGucksLive: its unny temps are rising
03:16 AM IchGucksLive: XXCoder, how is it in washington still winter around
03:16 AM XXCoder: it havent been winter for over a month here
03:16 AM XXCoder: very often and heavy rains
03:17 AM IchGucksLive: general in germany 2 but i live in a spare area
03:17 AM IchGucksLive: the Low"mountans" and the rine holding up most if it comes from the east
03:17 AM IchGucksLive: Weather is wear
03:18 AM IchGucksLive: Spain got Snow last week never got this in historie so late
03:21 AM IchGucksLive: im off 2 garden
03:28 AM XXCoder: MarcelineVQ: https://www.amazon.com/DBPOWER-TD0091-Sc-8108-Network-Multifunction/dp/B00A20KO18?tag=top505-20
03:49 AM gloops: picked up a working dust extractor at the car boot, powerful but a bit noisy
03:49 AM gloops: £5 lol
03:50 AM XXCoder: fancy
03:50 AM XXCoder: add some cyclones and you goos
03:50 AM XXCoder: good
03:50 AM gloops: will check the bearings out sometime
03:51 AM gloops: yeah ill rig something up with this, ill get some pics later, surprised it worked, dont think the person even knew what it was, it isnt old
03:51 AM XXCoder: got link? curipis
03:51 AM XXCoder: curious
03:52 AM gloops: it wasnt online - car boot sale, like a market
03:52 AM XXCoder: I know
03:52 AM gloops: it actually says 'air blower' on the motor, not extractor
03:52 AM XXCoder: just wanted to see what it looks like
03:53 AM gloops: http://media2.airmovers.com/media/catalog/product/cache/1/image/800x/9df78eab33525d08d6e5fb8d27136e95/a/d/advertising-inflatable-blower-large.jpg
03:53 AM gloops: its actually that haha
03:53 AM gloops: these are for blowing inflatable castles up i think
03:54 AM XXCoder: adversing it says
03:54 AM XXCoder: so its like dancing guys
03:54 AM gloops: it was me who didnt know what it was lol
03:54 AM XXCoder: hey 5 bucks and it can extract dust pretty good with good cyclone system
03:54 AM gloops: however it might do the same job
03:54 AM gloops: it has got very powerful jet of air - and suck in the inlet, it will do it
03:56 AM gloops: mine isnt the same exactly, its got an industrial looking motor and proper no volt switch, i thought for £5 its worth that for the motor
03:56 AM gloops: would easy drive my wood lathe
03:56 AM XXCoder: motors that large easily way more than $5
03:56 AM gloops: ahh well, something to play with
05:24 AM jthornton: morning
05:25 AM XXCoder: yo
05:25 AM gloops: hi jthornton
05:26 AM jthornton: what's up?
05:26 AM XXCoder: you buy rj45 plugs?
05:26 AM jthornton: me yea
05:26 AM XXCoder: how do you know if its quality rj45 for cat6?
05:26 AM XXCoder: because ones I got probably suck hard
05:27 AM XXCoder: I made 2 cables, both bad and one of those is still bad after severial attempts
05:27 AM jthornton: they have more little parts with them a thing that each wire goes in and a cross thing to separate the pairs
05:27 AM XXCoder: thats one I have, a 3 parter
05:40 AM jthornton: I like the ones that the wires can stick out for trimming after crimping
05:41 AM XXCoder: that seemed easiest
05:41 AM XXCoder: does that need special crimper?
05:41 AM XXCoder: what site you buy em from?
05:42 AM jthornton: no, regular crimper... I think I got them from Home Depot
05:46 AM miss0r: fragalot: so; any progress yet?
05:46 AM fragalot: miss0r: good timing, just came in for lunch :P
05:47 AM miss0r: I just got back from the th yearly farm visit with the kid :]
05:47 AM fragalot: finished the 1st motor bracket.. god this thing takes a lot of time on manual machines... especially because my Y isn't square to my X
05:47 AM miss0r: realy ? :D haha
05:47 AM fragalot: it's off by about 0.1mm over 60mm travel
05:47 AM miss0r: got any pictures?
05:47 AM gloops: you mean youre using a machine? haha thats cheating
05:48 AM fragalot: also - I trusted a datasheet rather than measuring the motor flanges, so that's about 13mm too big :p
05:48 AM miss0r: lol
05:48 AM XXCoder: jthornton: did you answer my questions? sorry disconnected
05:48 AM jthornton: <jthornton> no, regular crimper... I think I got them from Home Depot
05:48 AM gloops: i squared mine up with a poundshop rasp
05:49 AM XXCoder: cool thanks
05:49 AM XXCoder: where you buy em from?
05:49 AM XXCoder: https://www.amazon.com/Gold-Plated-Connector-itbebe-Pieces/dp/B07451LPHR/ I was considering this one
05:49 AM XXCoder: but reviews ehh
05:49 AM jthornton: that kind is more expensive than the regular cat 6 rj45
05:49 AM fragalot: miss0r: https://imgur.com/a/pAs5J
05:50 AM jthornton: yea those are good I think
05:50 AM fragalot: also, it's /impossible/ to tram the head in when flycutting on the mill I have
05:50 AM fragalot: if you move Z, it changes because it's so worn :P
05:50 AM XXCoder: thanks
05:50 AM jthornton: I like that you can verify the colors before you crimp
05:50 AM miss0r: fragalot: I don't understand your design there.... why are the bolt slots countermilled on what seems like the motor side?
05:50 AM fragalot: miss0r: because it's a 3-part bracket
05:51 AM fragalot: the outer holes are counterbored on the other side, which bolt the motor to this plate
05:51 AM miss0r: fragalot: Alright, I trust your design :)
05:51 AM fragalot: the other 4 are for little "L" brackets
05:51 AM fragalot: the only mistake I have on this part, is that the big counterbore for the motor flange is too large,.. but that's not the end of the world
05:52 AM miss0r: not _the_ world, just 'your' world
05:52 AM fragalot: anyway - i'm off to be all social & stuff
05:52 AM fragalot: ttyl!
05:53 AM XXCoder: jthornton: also got https://www.amazon.com/gp/product/B0716YRGDD/
05:53 AM miss0r: ttyl
05:55 AM XXCoder: gloops: tried that square diamond circle thingy yet?
05:59 AM jthornton: XXCoder: I have 2 of these http://www.kleintools.com/catalog/cable-testers-accessories/lan-scout-jr-continuity-tester
06:00 AM jthornton: I should put one up for sale I think
06:01 AM fragalot: Back!
06:01 AM fragalot: turns out i'm not needed for another while :P
06:01 AM XXCoder: yours looks a bit nicer but eh if it works it works for me :D
06:01 AM XXCoder: importantly it will tell me which end is bad by checking length
06:01 AM XXCoder: if its 0 well its end thats inserted lol
06:02 AM fragalot: miss0r: you're in this world too! .. Anyway it's obviously oversized so I can align it better... because the mill isn't square so the coördinates aren't perfect >.>
06:02 AM jthornton: I don't think mine tells me what end it is
06:02 AM XXCoder: you could abuse length that way
06:02 AM XXCoder: if length is equal to others and are shorted it will be either double length or same as others
06:03 AM XXCoder: while on "bad" short end it should show as length zero
06:03 AM XXCoder: I could be wrong though
06:04 AM XXCoder: http://www.cablinginstall.com/articles/print/volume-8/issue-3/cable-installer-tips/easy-open-short-testing-on-structured-wiring.html
06:49 AM jthornton: having to make standoffs for the corner posts on my chain link fence for a hot wire, seems no one makes any for 2.375 diameter posts
06:49 AM fragalot: what about 60mm ?
06:50 AM jthornton: I've not seen any 60mm standoffs for electric fence
06:53 AM gloops: well these TB6600 drivers will have to go
06:54 AM gloops: i cant f about with this anymore
06:55 AM fragalot: jthornton: inside or outside corner?
06:56 AM gloops: although im not convinced it is the driver, psu gives steady supply, driver starts up with lights on bright every time, but then just blacks out when running
06:57 AM jthornton: outside corners, inside would be easy just need an insulator
06:58 AM fragalot: found some from zareba but it looks naff
06:58 AM fragalot: http://www.zarebasystems.com/fi-shock-extension-bracket-insulator-iuclxy-fs
06:59 AM jthornton: yea I saw those and they look flimsy, might work for a line post but not a corner post
06:59 AM fragalot: diy it :p
07:00 AM jthornton: anyway I've made the part that same insulator will screw to yesterday, just need to burn out the standoff part and weld them together
07:03 AM jthornton: this is the prototype I made the other day https://imagebin.ca/v/3ySxFF5oqCNx
07:04 AM jthornton: I changed it to be longer and hold 2 insulators and be on a 45° to the fence line
07:05 AM ktc: Hi any later dvelopment of "https://github.com/jv4779/2x_laser" ??
07:08 AM jthornton: looks like it works to me
07:10 AM enleth: jthornton: I keep the ceramic bodies of old screw-in fuses to use them as insulators (mostly for heating elements), but I'm not sure if any suitable fuses are common in the US
07:10 AM enleth: we've got tons of IEC 60269 D-type fuses here, they're still being used in old buildings
07:10 AM enleth: that's a big, sturdy ceramic tube
07:11 AM jthornton: I've not seen a ceramic fuse in years... I've seen some that looked like a coke bottle in some German equipment I had many years ago
07:11 AM enleth: exactly this
07:11 AM jthornton: a bag of insulators is $5
07:11 AM Sabotend_ is now known as Sabotender
07:11 AM enleth: those bottle-shaped fuses are unfortunately still widespread
07:12 AM jthornton: I had to go to a ship supply to find them in New Orleans
07:13 AM enleth: no earlier than last month I gutted one panel that used those and replaced them with DIN rail breakers
07:14 AM enleth: "panel" is a big word actually, for a bunch of cast iron enclosures
07:14 AM sync: diazed are not that bad
07:15 AM enleth: http://images29.fotosik.pl/128/40b8a8e888265e5a.jpg something like this
07:15 AM sync: NH is actually quite common when the mains impedance is low
07:16 AM enleth: sync: except that a breaker is almost always better
07:18 AM enleth: fuses in electrical systems should only be used to protect parts of the system itself, e.g. on sub-panel connections, to provide selective coordination that breakers aren't capable of
07:19 AM enleth: actual loads (light fixtures, outlets, directly wired machines) should use breakers
07:20 AM sync: yes, at the point of load a breaker is probably better
07:20 AM enleth: that way, the fuses only act when something goes *very* wrong, like someone driving a forklift into a panel, or drilling into a cable connecting two panels
07:20 AM enleth: or a whole panel being overloaded
07:21 AM sync: yes, but it all depends
07:22 AM sync: I have a few things fused by fuses because breakers were cost prohibitive due to the large fault current that could happen
07:22 AM enleth: conversely, breakers should not be used for sub-panel connections, because they're not selective, a short circuit can easily knock out power to a large section of the system if breakers are used everywhere
07:23 AM enleth: well, unless those are selective breakers that cost 10-20x more
07:24 AM sync: I almost exclusively use selective breakers for that now
07:24 AM enleth: if you have the budget for those, sure
07:24 AM sync: as the TAB2007 requires layman operatable disconnect devices
07:25 AM enleth: ah, right
07:25 AM enleth: but that would be covered by a fuse and a separate isolator switch too
07:26 AM enleth: or actually disconnect switch if it's supposed to be disconnected under load
07:27 AM sync: yes but a selective breaker does it in one unit
07:27 AM enleth: again, if you have the budget, that's obviously the best solution
07:30 AM sync: I have not found them really cost prohibitive
07:30 AM sync: the ones with neutral cutoff are expensive tho
07:31 AM sync: for whatever reason
07:34 AM sync: I also used a few of those minized isolator switches
07:35 AM enleth: maybe the price ratios are different here, all selective breakers I can get are close to 20x the price of a regular breaker of the same class and current
07:36 AM enleth: could be a bit of a chicken and egg problem with supply and demand
07:36 AM sync: yeah
07:37 AM enleth: so I'm using fuses and disconnect switches/contactors
07:37 AM sync: I have a few residual voltage devices to replace
07:37 AM sync: really annoying things
07:38 AM sync: yeah, but my time is more expensive than putting a smcb in
07:39 AM ktc: Hi any later dvelopment of "https://github.com/jv4779/2x_laser" ??
07:40 AM sync: in the house there is now an external waste water treatment thing
07:40 AM sync: and there is ~30m of wire in the ground
07:40 AM sync: which has a isolation resistance of ~10MOhms
07:40 AM sync: which is enough to trip the residual voltage switch regularily
08:17 AM JT-Shop: the part the insulators mount to https://imagebin.ca/v/3yTJcQY5hRdQ
08:40 AM Loetmichel: Yesterday I thought of all you americans that stand in awe seeing europeans live in houses built 100s of years ago. My wife, my mother in law and me went out for dinner last night... to a place that once was a farm house and now is a mediterran restaurant. And the the door stock tells "AD 1776"... ;) It was a really nice dinner though, the interieur of the house is all anew while the walls
08:40 AM Loetmichel: and half timber structure is all original. :-)
09:11 AM Bruno: hallo zusammen, jemand hier der mir auf deutsch eine Frage beantworten kann?
09:12 AM Loetmichel: Bruno: sure
09:12 AM Loetmichel: but be aware that the germans here in the channel are not the ones that are really "experts" at linuxCNC
09:13 AM Loetmichel: it may be better to make the effort and try to spell out the question in english.
09:16 AM Bruno: mein Englisch reicht dazu leider nicht, ich versuche es dann später noch einmal, bis dahin erst einmal vielen Dank
09:19 AM Loetmichel: *Sigh* didnt i say "sure"?
09:28 AM IchGucksLive: hio all
09:29 AM IchGucksLive: Loetmichel, böse falle
09:29 AM Loetmichel: ?
09:29 AM IchGucksLive: sure=sicherlich
09:30 AM IchGucksLive: Loetmichel, there are germans i cnad belive who dont understand english ;-)
09:30 AM Loetmichel: yeah, thats what i meant
09:31 AM IchGucksLive: so why dident you answer german one word
09:31 AM Loetmichel: "sure we vcan answer ion german, but nost of us germans are not that "expert" with linuxcnc, which may be leading to some less than desireable answers"
09:31 AM Loetmichel: -v
09:31 AM Loetmichel: -o
09:32 AM IchGucksLive: then all my work is useless
09:32 AM * Loetmichel needs to sort his fingers again ;)
09:32 AM IchGucksLive: if people are blocked
09:32 AM Loetmichel: blocked???
09:32 AM IchGucksLive: it needed ONE Word to tell him that he can in German
09:33 AM Loetmichel: ah, you meant why didnt i tell him that in german?
09:33 AM IchGucksLive: yes
09:33 AM Loetmichel: sorry, my fault for using the main laguage in this channel
09:33 AM Loetmichel: i didnt even notice that could be a problem until he left.
09:34 AM IchGucksLive: some cand be pationt
09:35 AM Loetmichel: i assumed while not being able to speak most germany are able to read english pretty well
09:35 AM Loetmichel: never occured to me otherwise
09:35 AM ziper: how bad is using a tap to cut tapered threads compared to other methods
09:35 AM Loetmichel: +it
09:37 AM Loetmichel: IchGucksLive: also sag ihm "entschuldigung" von mir, es war nicht meine absicht ihn zu vertreiben, im gegenteil.
09:37 AM IchGucksLive: ziper, https://www.gesswein.com/p-10547-tapered-thread-mandrels.aspx
09:41 AM ziper: I was thinking more like pipe thread
09:41 AM IchGucksLive: ziper, there are cheep irons
09:41 AM IchGucksLive: fits all sizes RG ...
09:44 AM rmu: hmm. don't ask to ask...
09:44 AM IchGucksLive: Loetmichel, schneidkluppe in englisch
09:45 AM IchGucksLive: ziper, https://www.ebay.de/itm/Schneidkluppensatz-8tlg-Schneidkluppe-Gewindeschneider-Rohrschneider-Kluppe-SE/222587662389
09:46 AM IchGucksLive: ziper, im searching for the english equal i cand find
09:46 AM rmu: i need new spindle bearings. anybody now a reputable (and affordable) source in de/at, need 2 bearings type 7007 and 2 type 7005, speed up to 24000RPM
09:46 AM IchGucksLive: rmu, TUSNELDA
09:46 AM IchGucksLive: rmu, Kugellagershop Berlin
09:47 AM rmu: IchGucksLive: danke *checking
09:47 AM rmu: *
09:48 AM rmu: IchGucksLive: "tap" for "innengewindeschneider" and "die" for "schneidkluppe" AFAIK
09:50 AM IchGucksLive: rmu, there are eyal bearings for cars about 25Euros
09:50 AM IchGucksLive: eqal
09:51 AM rmu: with the same speed rating?
09:52 AM IchGucksLive: i guess not that fast
09:52 AM rmu: my local SKF distributor wants 800€ for those 4 bearings... :(
09:52 AM IchGucksLive: as cars tyrers dont make 24k rpm

10:14 AM ktc: rmu: chinese spindle all use these bearings
10:28 AM IchGucksLive: hi
10:32 AM rmu: these seem to be spindle grade and are about 72€ pp https://www.kugellager-express.de/spindellager-b7007-c-t-p4s-ul-35x62x14-mm
10:35 AM rmu: hmm i thought those were FAG, but seems they are noname just using the same code
10:38 AM IchGucksLive: rmu, let me grap the skf catalog
10:38 AM rmu: 7007 CDGA/P4A AKF should work

10:53 AM IchGucksLive: im off till later
11:17 AM fragalot: hi
11:18 AM jthornton: what is the metric size of framing lumber that is near to a 2" x 6" which is really 1.5" x 5.5"
11:19 AM fragalot: 42x140
11:19 AM jthornton: thanks
11:19 AM fragalot: or 145, can't remember
11:19 AM fragalot: you can also get 50x150
11:19 AM jthornton: 140, 145 what ever it takes
11:19 AM jthornton: cool
11:53 AM miss0r: Apparently theres a function in my mazda 5 central locking remove, that opens the windows. I have no idea how it works. I have two buttons 'lock' 'unlock' on there, but now I have twice managed to open the windows with it. Both times I was completely unaware what was going on. Today I managed to do it while it rained, only to realize it after....
11:53 AM miss0r: WTF !
11:53 AM fragalot: hold down the unlock button
11:53 AM fragalot: and it opens
11:53 AM fragalot: hold down the lock button
11:53 AM fragalot: and it closes
11:54 AM miss0r: ...okay, that works
11:54 AM * fragalot is trying to think about what to do about the non-squareness of his RF45
11:54 AM miss0r: But that is annoying when you have no idea about it :D
11:54 AM fragalot: i'm not sure if it's just wear, or if the thing has never been perpendicular to begin with
11:54 AM IchGucksLive: fragalot, how can this bee
11:55 AM IchGucksLive: its a X table
11:55 AM fragalot: IchGucksLive: the Y is not square to X by 0.15mm/100mm
11:55 AM IchGucksLive: it only got 150mm
11:55 AM fragalot: the RF45 has more than 150mm travel
11:56 AM miss0r: Other than scraping the saddle, I don't know
11:56 AM IchGucksLive: there are 2 screws at the side for tilding
11:56 AM fragalot: IchGucksLive: where?
11:57 AM gloops: flat plate and angled gibs?
11:57 AM IchGucksLive: if it is the n2f
11:57 AM IchGucksLive: hi deanforbes
11:58 AM fragalot: it's a clone offered through HBM in 2008
11:58 AM miss0r: fragalot: http://cdn1.grizzly.com/manuals/g0484_m.pdf side 34
11:58 AM fragalot: with a larger table
11:58 AM miss0r: I see no way of ajusting it
11:58 AM IchGucksLive: fragalot, http://s3.cnccookbook.com/CCMillTramAdj.html
11:58 AM fragalot: IchGucksLive: oh no, the tram isn't the issue
11:58 AM gloops: twisting the carriage wont make it move square though
11:58 AM fragalot: and I have a mod similar to that
11:59 AM fragalot: (mine has a much larger gap there so it's less elegant, but the principe is the same)
11:59 AM fragalot: IchGucksLive: i'm talking about X and Y, not Z
11:59 AM fragalot: if I indicate in a DIN/00 square along X, and indicate the Y,.. it's off.
11:59 AM fragalot: a lot.
11:59 AM miss0r: fragalot: So, you sould've ordered everything from me then, ay ? :þ
12:00 PM fragalot: miss0r: at the moment i'm squaring it all up sticking straight up in the air, which works well
12:00 PM fragalot: and as far as the hole coordinates go.. calculator
12:00 PM miss0r: syre
12:00 PM miss0r: with a u
12:00 PM fragalot: which is a right paint
12:00 PM fragalot: -t
12:00 PM IchGucksLive: isend there a harden tiny pice of steel to get the trimm alredy
12:01 PM IchGucksLive: along the 45Deg
12:01 PM fragalot: IchGucksLive: my Z column is perfectly square (after I spent 3 days getting that straight)
12:01 PM fragalot: and the head is also perfect
12:01 PM fragalot: the issue is the table itself, and the saddle
12:01 PM miss0r: most likely the saddle
12:02 PM IchGucksLive: dovetail guide
12:02 PM fragalot: well yeah, that's the part that "decides" how square it will be :P
12:02 PM fragalot: http://cdn1.grizzly.com/manuals/g0484_m.pdf page 32, part 26
12:03 PM miss0r: fragalot: Take the saddle off and scrape it in. you will be happier with that
12:03 PM fragalot: miss0r: i'm sure I would be, but this will delay the mill by another month or 2 :P
12:03 PM miss0r: That is true... but what are your alternatives? nothing sucks more than a mill out'a square
12:03 PM fragalot: plus I really need to get me a way to lift it off
12:04 PM fragalot: very true
12:04 PM miss0r: lift it off? the table?
12:04 PM fragalot: table & saddle
12:04 PM miss0r: That thing can't be more than 25-30kgs ?
12:04 PM miss0r: or am I seriously underestimating the design?
12:04 PM fragalot: I think the individual parts will be around that, but to scrape them in i'll need to lift them on & take them off A LOT.
12:05 PM fragalot: when I first got it, we took it down to 3 parts.. the base & table, the Z column, and the head
12:05 PM miss0r: can't you just do it right the first time? :D
12:05 PM fragalot: all of them required 2 people to lift, and a lot of cursing :P
12:05 PM miss0r: lol
12:05 PM IchGucksLive: the problem is as they are ontop of etch you need to do it on a other mashine
12:06 PM IchGucksLive: as you lose the system you are not able to scratch the y
12:06 PM miss0r: you just need the body of a danish viking :D
12:06 PM fragalot: miss0r: :) I imagine you're quite a bit taller than I am
12:06 PM * Loetmichel just applied all the contents of both of these cans onto the BMW convertibles canopy... hopefully thats waterproof again now... (MAAAN, that stuff REEKS of solvents!) -> https://www.ebay.de/itm/161704339390
12:06 PM fragalot: and having had a desk job for the past 6 years also hasn't helped
12:06 PM miss0r: I wouldn't know ;)
12:07 PM miss0r: fragalot: how does that mill compare to the X2 ?
12:07 PM fragalot: syyl: have you scraped in your RF45 table saddle?
12:07 PM fragalot: miss0r: a lot bigger
12:08 PM Loetmichel: fragalot: i know that feeling. i used to do mobile stages for 10 years. now i am a production manager in a computer company for the last 9... stamina: gone ;)
12:08 PM fragalot: Loetmichel: yup :D
12:09 PM miss0r: fragalot: Then how does it compare to the ZX7045
12:09 PM fragalot: at least the willpower remained
12:09 PM fragalot: miss0r: same machine
12:10 PM miss0r: ahh... can't you just take off the table and leave the saddle for the next lift?
12:10 PM fragalot: perhaps
12:10 PM fragalot: but i'd need to get me a good reference surface first
12:11 PM fragalot: my cast iron surface place is both too small, and completely the wrong tool to scrape in dovetails :D
12:11 PM miss0r: You can always ship it to me, I'll gladly overcharge you for squaring it up ;)
12:11 PM IchGucksLive: i woudt mesure the high point mark it unmount it and scratch 1/4
12:11 PM fragalot: miss0r: at that point i'm sure it'd be cheaper to just buy a better mill xD
12:12 PM miss0r: hehe
12:12 PM fragalot: miss0r: https://i.imgur.com/ARLay6M.jpg
12:12 PM fragalot: that thing
12:12 PM IchGucksLive: fragalot, the 0,15 is in tolerance to the ISO
12:12 PM miss0r: is the error consistent? (can you make the error move, if you 'rough it up' a bit?)
12:12 PM fragalot: IchGucksLive: for what standard???
12:12 PM IchGucksLive: m
12:12 PM fragalot: miss0r: fairly
12:13 PM IchGucksLive: 7168
12:13 PM miss0r: hmm... I would consider starting out by just stoning the mating surfaces, and see if there isn't just a dimple in there
12:14 PM fragalot: I really need to find me some precision stones
12:14 PM miss0r: I see the error: You are using electric heating one just ONE side of the machine, no wonder its bend on'ya :D
12:14 PM fragalot: the ones I have now have just been manually lapped on a diamond plate, but i'm not convinced that plate is as flat as it once was
12:14 PM fragalot: miss0r: lol
12:14 PM miss0r: Don't worrie about that. Just take your two flattest stones and rub them together for a while, with some alcohol
12:15 PM miss0r: wipe em off, dry rub'em together and blow it off. Then its plenty fine for what you need it to do here
12:15 PM fragalot: I have some stones that are a perfect example of why the 2 stone method isn't actually reliable :P
12:15 PM fragalot: they both look like ( and the curve matches perfectly
12:16 PM miss0r: well, it doesn't work with small boulders from the yard, I tried to warn'ya
12:16 PM miss0r: I keep three stones, I square to eachother
12:16 PM fragalot: I use a diamond lap from thingybobber
12:16 PM fragalot: DMT
12:16 PM miss0r: that works too
12:17 PM fragalot: anyway - I guess I'll try stoning it
12:17 PM fragalot: need to take it all apart to put in some oil grooves anyway
12:17 PM miss0r: no exessive stoning, just give it a rub and see if it has any odd high spots
12:18 PM fragalot: but before I do that,. I think i'll test the squareness along the whole travel of the table
12:18 PM miss0r: You need to be a special kind of stupid to fsck up the saddle onj that machine
12:18 PM fragalot: miss0r: previous owner ran it on 220V for 8 years, and I don't think he's ever changed the oil, or even oiled the ways once
12:18 PM fragalot: it's a 400V machine
12:19 PM miss0r: ...ahh
12:19 PM fragalot: Yup. :P
12:19 PM miss0r: well, there you have it - A special kind of stupid
12:19 PM fragalot: well it was cheap
12:20 PM fragalot: and delivered to my doorstep
12:23 PM miss0r: can't argue with that
12:23 PM miss0r: How long have you known this error to be there?
12:24 PM fragalot: only made a part large enough to notice today
12:24 PM fragalot: and it's the first time i've tried squaring something along that plane
12:24 PM fragalot: so.. a few hours?
12:24 PM miss0r: :]
12:26 PM miss0r: I know a guy who is excellent at scraping this stuff in... He is somewhat pricy though :D
12:26 PM fragalot: i'd rather not spend more than the mill is worth
12:26 PM fragalot: which is like €600 as a good drill press :P
12:26 PM miss0r: Hehe, I get that
12:27 PM miss0r: But you are not realy going to spend alot of money on a new mill, with your CNC build comming along, that will take over that stuff anyway ;)
12:27 PM fragalot: Yup.
12:30 PM fragalot: i'm kindof tempted to scour ebay for a dovetail straightedge
12:30 PM fragalot: but at the same time i want something to check it first
12:30 PM fragalot: at which point I may as well make one
12:30 PM fragalot: which means I need to get a larger surface plate
12:30 PM fragalot: which in turn requires somewhere to put it
12:30 PM fragalot: .. I need a bigger shed
12:31 PM IchGucksLive: fragalot, we all need always a biger mashine#
12:31 PM fragalot: IchGucksLive: I need an accurate machine, not a bigger one :P
12:31 PM fragalot: perhaps I should invest my life savings in euro millions
12:31 PM fragalot: liquidize my assets
12:31 PM IchGucksLive: buy a maho 500
12:31 PM fragalot: IchGucksLive: can't fit that
12:31 PM IchGucksLive: or a 400p
12:32 PM IchGucksLive: the 400 is the same size as a rf65
12:32 PM fragalot: i'm limited to something that fits through an 83cm wide path, and can be hand lifted in place.
12:32 PM IchGucksLive: if you take the X and Y of you can
12:33 PM IchGucksLive: if you get a older one it might be XZ
12:33 PM IchGucksLive: as lots of G18 mashines under 1,5k euros
12:33 PM fragalot: where?
12:34 PM IchGucksLive: maschinesucher finds all over
12:38 PM fragalot: I refuse to use machinesucher as it has a little belgian flag for "french"
12:38 PM fragalot: :P
12:39 PM IchGucksLive: fragalot, what are you using
12:39 PM IchGucksLive: ebay local
12:40 PM fragalot: problem with ebay is that listings are likely to be in dutch, and our word for mill is so ambiguous that 95% of the listings are either for woodworking or agriculture
12:40 PM IchGucksLive: https://www.ebay-kleinanzeigen.de/s-cnc-fr%C3%A4smaschine/k0
12:43 PM IchGucksLive: full retrofit linuxcnc GMS 2.5k
12:44 PM IchGucksLive: Wagner FCW450
12:46 PM IchGucksLive: ok im off for today IF BRUNO joins in POLEASE tell him im always at 7PM
12:48 PM fragalot: http://crispyn.be/images/20171122_060540.jpg?crc=80431698 <= that one is for sale near me
12:49 PM fragalot: and as much as i'd like it
12:49 PM fragalot: there is no way I can get it into the shed xD
12:49 PM gregcnc: that's a substantial machine
12:50 PM fragalot: Yup
12:50 PM fragalot: I like crispyn, very friendly dealer
12:50 PM fragalot: they also import RF45 clones, but have 2 ranges of it.. the standard, and their reworked modeol where everything is scraped in by hand
12:51 PM fragalot: alas, the price reflects that, lol
12:54 PM miss0r: Have you fixed it yet ? :D
12:54 PM fragalot: no, it's pissing it down & I don't feel like walking to the shed anymore today xD
12:55 PM miss0r: nice attitude :D Can't you just bring a laptop along for the ride? (use it as shelter, to not mess up your hairstyle)
12:55 PM miss0r: or, just chat to us from there
12:55 PM fragalot: wifi doesn't reach there. I've been meaning to run a cable, or get a wifi extender, but that hasn't happened yet
12:57 PM miss0r: you need that, bad.
12:57 PM fragalot: Yup
12:57 PM miss0r: Can't you just setup a wifi hotspot on your phone?
12:57 PM fragalot: I tried that once and windows decided to download a 2gb update
12:58 PM fragalot: & my work phone's contract only covers .5gb
12:58 PM fragalot: which is ridiculously low for modern day use
12:58 PM fragalot: also - i'm already ordering an extender :D
12:58 PM miss0r: wow, yeah. I have 40gb I think
01:01 PM fragalot: repeater ordered.
01:01 PM miss0r: but that does not satisfy my curiosity 'now'... :)
01:01 PM fragalot: what do you want to know?
01:02 PM fragalot: rain stopped :P
01:03 PM miss0r: Just wanted you to take it apart, snap a few photos and stone it ect :D
01:04 PM fragalot: Yeah that's not happening today :D
01:04 PM miss0r: :D
01:05 PM gloops: right, couple of leadshine drivers on the way, tb6600 is pure shit, anyone who says they are good on these cnc blogs must be on the payroll
01:07 PM gloops: if they want £7 that bad, id rather give them £7 and them tell me not to buy their shitty time wasting crap
01:11 PM gloops: trump is 100% right
01:12 PM fragalot: what did he say this time
01:13 PM gloops: tariff china out of existence
01:20 PM miss0r: fragalot: Doing some sort of spring cleaning in here (yes, it is much needed). I'm getting rid of my x-carve now. I think my brother in law would love to have it in his shop (that poor fool), but that way I still have 'some' access to it, should I suddenly need it
01:21 PM fragalot: I looked at getting an x-carve a few times, but it just looks like such a dinky toy
01:21 PM miss0r: yeah, I did alot of reinforcements to it, to make it into a decent wood router
01:22 PM miss0r: I actualy did a cutout in 0.5mm steel plate with it :o
01:22 PM fragalot: o.O
01:22 PM miss0r: I carved a CS:GO logo in the computer cabinet for my neighbors 10 year old kid :D
01:22 PM fragalot: :D
01:22 PM miss0r: the only real project I made with this thing was my subwoofer case
01:23 PM miss0r: Other than that, i just use it as a table with an annoying height
01:23 PM fragalot: lol
01:23 PM fragalot: I saw it as an engraver
01:23 PM fragalot: but then I saw how much Z variation it's got
01:24 PM fragalot: and how flexible the frame is, so if you have it upstairs & someone fills the bath the thing warps :P
01:24 PM miss0r: hehe yeah, thats why I reinforced it ;)
01:26 PM miss0r: also; when i got this one (I got it for free, mind you), it was equipped with the 'minimal' spindle, if you can even call it that. It was just a low power brushed DC motor with a tiny bearing in each end. Then they had glued an ER11 collect chuck on the output shaft. That thing was absolutly WORTHLESS
01:26 PM fragalot: hahah
01:27 PM miss0r: and it had been run for a while, so it was absolutly sloppy! we are talking 1mm radial play
01:27 PM fragalot: that's so you can knurl things
01:27 PM miss0r: no wonder the guy just wanted to throw it out. (he didn't know much about these things)
01:28 PM miss0r: Sure :] I made a few new brackets for and and installed a good quality dewalt router to it
01:29 PM miss0r: that and I sandwiched a 4mm steel plate between the two seprate x-axis guides, which were flopping in the breeze
01:30 PM miss0r: plus a few other low budget solutions to make it even remotely usable... haha: also: when I power it up, I need to use a large woodworkers angle & force a few steps on one of the y axis steppers to get it just about within reason in squareness
01:30 PM fragalot: >.<
01:31 PM miss0r: routers with two steppers using belts are prone to that error. Not that the frame is always off like this one, but that design _requires_ that the belts are setup exactly the same(linear location of the teeth) & the stepper angle needs to be calibrated
01:32 PM gloops: well, i have built the router that cannot be improved
01:32 PM gloops: but still im waiting for the electronics equal to it
01:37 PM fragalot: gloops: what's the problem?
01:37 PM gloops: shit couple of drivers
01:38 PM fragalot: I thought you replaced those already?
01:38 PM gloops: yes i did with the same junk
01:38 PM miss0r: gloops: give us a quick update on the error you are experiencing
01:39 PM fragalot: gloops: and it's the same issue?
01:39 PM gloops: it isnt so much an error as just crap hardware
01:39 PM miss0r: you are making it hard for us to lend you a hand with that description
01:40 PM gloops: fragalot no not the same issue, i had only really used the tb6600s for jogging up and down, homing etc, they seemed fine, however their tendency to drop the ball after more than a minute or two cutting has now become apparent
01:40 PM fragalot: gloops: are they warm?
01:40 PM gloops: warm yes, but not very warm or hot
01:41 PM gloops: they just power off for no apparent reason, switch power off and back on - they light up again
01:41 PM miss0r: Are you supplying the steppers with enough juice?
01:42 PM miss0r: okay, either you are having a power supply issue, or they ARE getting too hot
01:42 PM gloops: ive tried the max and lower settings, no different
01:42 PM gloops: ive monitored the voltage coming from psu it seems constant
01:43 PM fragalot: is it both X and Z that do it, or just one?
01:43 PM gloops: mainly one driver - which is practically useless, the other same driver has done it once or twice
01:44 PM gloops: i changed one of these before for the same thing
01:44 PM miss0r: have you tried measuering the current from the PSUs while trying to provoke an error?
01:45 PM miss0r: hmm.. what is the voltage from your power supplys?
01:45 PM gloops: well ive only got multimeter, difficult to do with one pair of hands and eyes, have not seem the moment the driver stops
01:45 PM fragalot: tbh.. That's what you get when yuo go for the cheapest option rather than buying american made
01:45 PM gloops: ive had it to 39v and down to 28v
01:46 PM miss0r: ...? down to 28volts ?
01:46 PM gloops: fragalot further reading on these drivers shows quite a lot of people saying the same thing
01:47 PM gloops: its a 24-48v supply, ive had it to the max the drivers will take and down to 24v - no difference
01:47 PM miss0r: alright
01:49 PM miss0r: I would love to see a photo of your box where you have them installed, the step drivers
01:49 PM gloops: ive just closed a blog i was reading, apparently if you change one component - opto something, theyre totally reliable
01:50 PM miss0r: an optocoupler ?
01:50 PM gloops: well the other 2 different drivers have no problem, not lost a step yet, theyre in the same compartment
01:51 PM gloops: maybe that yeah
01:51 PM fragalot: optocouplers are likely to lose steps if they are bad or soldered improperly, but they won't fix the issue requiring the driver to reboot
01:51 PM gloops: -- I'm also using TB6600 based controllers... these super-cheap ones:
01:51 PM miss0r: so, the issue is with the two steppers that are running the same axis/sharing an input signal?
01:51 PM gloops: and they're fine apart from after about 10 minutes any of X/Y axes will die, all indicator lights off on driver, until I power cycle it. They don't seem very warm and they don't auto-recover as you might expect if it were overheating. It's perhaps too different from your circuit but maybe someone here recognises the problem.
01:52 PM gloops: miss0r no that axis is fine, different drivers / psu
01:52 PM gloops: its the y axis and z - z is not so bad, but it has missed, which is bad really, it cant do that lol
01:53 PM gloops: that is the same problem as i get, as that kid posted
01:55 PM gloops: the top post someone identifies the problem, and solution for these drivers http://www.mycncuk.com/threads/11083-TB6600-HY-DIV268N-5A-Problems-and-possible-solutions
01:55 PM fragalot: which ones are you getting instead?
01:56 PM gloops: DM542T
01:56 PM fragalot: his issue sounds nothing like what you have
01:56 PM fragalot: with the controller requireing a reboot
01:57 PM gloops: not expensive by any means, i wanted 2 more dm542a s as the ones i have have proven reliable so far, forgot about them from the start
01:57 PM fragalot: that's really something that is either caused by:
01:57 PM fragalot: - bad solder joints
01:57 PM fragalot: - heat
01:57 PM fragalot: - electrical noise & the chip fucks up
01:57 PM gloops: a reboot - power cycle
01:57 PM fragalot: same thing for embedded systems
01:58 PM gloops: well thats what mine do, power off/on theyre back
01:58 PM rmu: sorry to interrupt. gloops: what power supplies do you use?
01:58 PM gloops: i dont know just some nameless chinese things
01:59 PM gloops: the ebay psu
01:59 PM rmu: you mentioned you have X and Y/Z on different PSUs?
01:59 PM gloops: right
02:00 PM rmu: the drivers are configured for the proper motor current?
02:00 PM gloops: if 2 drivers are on same psu, if psu fails - both drivers go out
02:00 PM gloops: that doesnt happen
02:00 PM rmu: otherwise, PSUs on X and Y/Z are identical?
02:00 PM gloops: ive had the drivers configured for any possible eventually
02:01 PM gloops: yes
02:01 PM rmu: is this some kind of switch mode PSU?
02:01 PM gloops: these drivers are junk, its fraud to even claim theyre stepper drivers
02:02 PM rmu: blaming the drivers will not solve your problem ;)
02:02 PM rmu: if they are switch-mode, it could help to add some (large-ish) capacitors next to the drivers
02:03 PM fragalot: and also TVS diodezs
02:03 PM rmu: if the driver has to brake the motor, it will actually feed the current back into the PSU, and some switch-mode PSUs don't like that
02:03 PM gloops: this kind of thing https://www.ebay.co.uk/itm/480W-Switching-Power-Supply-48V-10A-DC-Fr-CNC-Stepper-Servo-Motor-Driver-Spindle/123070801507?
02:04 PM rmu: the capacitor helps with that
02:04 PM fragalot: oh wow they even cheaped out on the ventilation holes
02:04 PM gloops: rmu that doesnt happen with my other drivers
02:05 PM rmu: gloops: what other drivers
02:05 PM gloops: dm542a
02:05 PM gloops: the old faithful
02:05 PM fragalot: so the X is on dm542a's?
02:05 PM fragalot: or Y,..
02:05 PM gloops: yes
02:05 PM gloops: the X - 2 motors
02:05 PM fragalot: that is a critical bit of information we were not given up to now :P
02:06 PM gloops: what difference does it make which axis theyre on?
02:07 PM fragalot: the difference being that the axis you kept referring to as "working fine" uses a different set of drivers than the one that doesn't doesn't strike you as "this information could have been helpful to share"? :P
02:07 PM gloops: the main problem is here is lost time, ill receive the new drivers later in the week, fit them, and the problem is over
02:07 PM gloops: i said that 3 times already lol
02:07 PM fragalot: not when I was paying attention. :D
02:09 PM miss0r: that cannot possibly be gloops fault... :)
02:09 PM rmu: gloops: even the chinesium-drivers should not just crap out, i suspect you have either a thermal problem, flaky PSU, or bad connection to motors.
02:09 PM fragalot: especially not both
02:10 PM gloops: another thing, you dont have a big choice if you want any of this stuff quick here, very limited what is actually on the island and can be posted in a couple of days
02:11 PM fragalot: are you sure?
02:11 PM fragalot: I bought my drivers and motors from a UK vendor
02:11 PM miss0r: I have to run. See you guys around
02:11 PM fragalot: cya miss0r
02:11 PM gloops: motors yes, and tb6600s and high end drivers maybe
02:12 PM gloops: one of the reasons i went for tb6600s was because theyre everywhere
02:12 PM rmu: gloops: if you really want to understand power supply issues with steppers check out the gecko drive FAQ
02:13 PM gloops: ok, i will but will have to be later now
02:13 PM rmu: gloops: that stuff is relevant for all stepper drivers, not only geckos
02:14 PM rmu: gloops: https://www.geckodrive.com/support/step-motor-basics/power-supply-basics.html
02:15 PM rmu: gloops: and try to take a picture of your electrical wiring and post it somewhere
02:30 PM gloops: ok rmu, i see the point about return power going back from decellerating motor
02:31 PM gloops: but if this is the problem, why doesnt it happen when jogging at top speeds?
02:31 PM gloops: i mean, it would happen every time i use fast speed
02:31 PM fragalot: not really
02:32 PM syyl: fragalot
02:32 PM fragalot: issues like this are semi-random; and your jog deceleration might be slower than what is needed for a standard rapid
02:32 PM syyl: nope, no scraping on that machine yet
02:32 PM fragalot: hi syyl
02:32 PM fragalot: syyl: do you have any issues with X and Y not being entirely square at the furthest travel towards you?
02:32 PM syyl: nope :)
02:32 PM syyl: even as the ways look crazy
02:33 PM syyl: the overall geometry is quite good
02:33 PM fragalot: guess i'll be taking mine apart then :P
02:33 PM syyl: oh i lied
02:33 PM CaptHindsight: what is your best impression of a stepper motor?
02:33 PM syyl: i scraped the gibs
02:33 PM syyl: because they where a complete mess :D
02:33 PM pcw_home: switching supplies often don't have sufficient output capacitance to absorb decel energy without an excessive voltage rise
02:33 PM fragalot: syyl: I guess that'd be a good place for me to start
02:33 PM gregcnc: happy April snow?
02:34 PM gloops: pcw voltage rise - output?
02:34 PM fragalot: syyl: any idea for a good source for a dovetail "master" ?
02:34 PM pcw_home: linear supplies typically have very large output capacitance just for filtering
02:34 PM syyl: i made mine myself
02:34 PM syyl: out of durabar
02:34 PM fragalot: I guess that's an option
02:35 PM syyl: richard king is selling scraping tools at the moment i think
02:36 PM gloops: so maybe motor return through the driver to the psu is causing a voltage spike back to the driver?
02:36 PM fragalot: syyl: does he sell them online or do I need to contact him directly?
02:36 PM syyl: i think he had them on ebay
02:36 PM syyl: just read it on practical machinist
02:36 PM gloops: in any case, i cant do anything about that, i need drivers that deal with it
02:36 PM syyl: didnt look, because shipping to germany would be a killer
02:37 PM fragalot: not worth checking out for me either then
02:38 PM fragalot: shipping to belgium isn't cheaper than to germany :P
02:38 PM syyl: haha
02:38 PM syyl: yes
02:38 PM rmu: gloops: the driver can't just eat the kinetic energy of the motor or make it disappear
02:38 PM fragalot: gloops: TVS diodes are cheap & would probably solve the problem
02:39 PM gloops: but it doesnt happen on the other axis
02:39 PM rmu: gloops: theory: motor feeds back current to PSU, causes voltage spike, triggers protection of PSU, PSU shuts off, driver goes into undervoltage or brownout and waits to be powercycled
02:39 PM gloops: where you have 2 motors feeding back together
02:39 PM gloops: that sounds reasonable yes rmu
02:40 PM gregcnc: if the motor is generating voltage i don't think that would happen.
02:40 PM gregcnc: but there could be some time after voltage drops to when the PSU wakes up
02:41 PM rmu: gloops: perhaps more friction on X axis, and Z axis moving down needs braking
02:42 PM fragalot: or the other drives have a better circuitry with internal clamping diodezs
02:42 PM rmu: gloops: nevertheless, post photos
02:42 PM fragalot: why does that z always appear when I type diodezs >.<
02:42 PM fragalot: DIODEZS
02:42 PM fragalot: what
02:42 PM fragalot: diodes
02:42 PM fragalot: weird
02:43 PM fragalot: seems if I type E and S in rapid succession my laptop throws in a free Z
02:43 PM gloops: as much as im eager to learn, at this point im willing to buy a solution for this, ive seen the thing work, its ok, i need to get it working
02:44 PM gloops: reliably
02:44 PM rmu: gloops: so get a toroid transformer, rectifier, capacitor, and gecko drives ;)
02:45 PM gloops: well, lets not get too excited lol
02:45 PM gregcnc: capacitance or shunt regulator
02:46 PM fragalot: this is such a weird keyboard bug
02:46 PM gloops: ill get similar drives to the other axis, ill get another psu, thats all it needs
02:49 PM JT-Shop: yep torid + gecko 80v drives are a super combination.
02:49 PM JT-Shop: Antek if you can get them over there are super power supplies
02:50 PM JT-Shop: not to be confused with Antec...
02:56 PM gloops: how about leadshine drivers?
02:57 PM JT-Shop: everything I hear about genuine leadshine is good
02:59 PM gloops: well, im not sure if the 2 ive got are genuine but ive had no problem with those, got 2 very similar coming this week
03:04 PM fragalot: JT-Shop: https://imgur.com/gallery/KiqZ03t
03:05 PM gloops: forgot to get chicks vid again..may have some baby goats any day too
03:09 PM gloops: whats happening with this plane collision in Germany ?
03:17 PM fragalot: hey pink_vampire
03:17 PM pink_vampire: hi fragalot
03:46 PM dioz: i use ~300kwh a month, how big a solar panel do i need?
03:46 PM dioz: to generate say.. ~130% of that monthly
03:47 PM fragalot: there are better places to ask that question
03:47 PM dioz: where?
03:47 PM dioz: TELL ME
03:47 PM fragalot: it depends a lot on your location, local regulations (taxes?), roof angle, direction, etc..
03:47 PM fragalot: try searching for solar forums in your country
03:49 PM gloops: dioz - DIY wind generator
03:49 PM dioz: turbines
03:49 PM fragalot: you're actually not allowed to put those up here
03:49 PM fragalot: fairly big fines on them too
03:49 PM phipli: hydro?
03:50 PM fragalot: phipli: might as well drill a thermal well whilst you're at it too
03:50 PM gloops: you can buy them in BQ here, or you could anyway
03:50 PM phipli: fragalot, my parents have the perfect garden for hydro - I'm very envious
03:50 PM phipli: stream that drops about 30 foot
03:50 PM fragalot: nice
03:51 PM phipli: next house I get will have some very specific requirements
03:53 PM Deejay: gn8
03:54 PM gloops: n8
03:55 PM rmu: 300KWh is not THAT much
03:55 PM gloops: https://www.theguardian.com/business/2009/feb/06/windpower B&Q pulled the turbines, wow didnt realise it was that long ago
03:57 PM gloops: The results of the study, which tested different types of turbines in different locations, showed the worst performing devices provided less energy than needed for a conventional lightbulb for an hour, or even to power the turbine's own electronics.
03:58 PM fragalot: Yup. wind needs to be large & in a windy location to make sense
03:59 PM gloops: hydro has to be best, but not something many people can undertake on their own property
04:00 PM dioz: i would think a wind turbine would be dangerous
04:00 PM dioz: TBH
04:00 PM dioz: those things get bucking hard if the winds right
04:00 PM dioz: and imagine it blowing up and ending up in your neighbours eye socket or somethin
04:01 PM fragalot: There you have the reason why they aren't allowed here
04:01 PM fragalot: :)
04:01 PM gloops: one on a farm near here, id say about 30ft high, been shredded twice, he never bothered with it again, its still there in a sorry state
04:03 PM phipli: hydro is the best, but high capital cost
04:04 PM phipli: and requires the right... landscape
04:04 PM dioz: i've seen some decent DIY hydro rigs for people who live near streams
04:04 PM dioz: low cost setups that generate a fair amount of power
04:04 PM phipli: if you don't have the earth moving kit though
04:04 PM dioz: yash
04:04 PM phipli: even putting in the pipework can be expensive
04:04 PM fragalot: that's because they aren't worried about efficiency
04:05 PM fragalot: same principle behind those water hammer pumps
04:05 PM fragalot: nobody cares if you lose 95% of the energy (or water) available if it's all free and there is an endless supply :P
04:06 PM gloops: the screw turbines are big fish killers though
04:06 PM phipli: you filter the supply
04:06 PM phipli: put a screen at the inlet
04:06 PM phipli: and for diy you'd do better with a crossflow
04:07 PM gloops: how about a plain old water wheel?
04:07 PM phipli: crap efficiency
04:07 PM phipli: crossflow is similar, but better
04:07 PM fragalot: at least go for a pelton wheel if you're going down that route
04:07 PM phipli: http://cink-hydro-energy.com/wp-content/uploads/2017/03/horizontal.gif
04:08 PM phipli: two chances to extract energy
04:08 PM gloops: i dunno the old water wheel, low environmental impact, actually rather pleasant thing to go by
04:08 PM phipli: fragalot, pelton has some requirements that are hard to meet
04:08 PM fragalot: it does
04:09 PM phipli: https://upload.wikimedia.org/wikipedia/commons/b/bf/Water_Turbine_Chart.png
04:09 PM phipli: for home stuff, crossflow or kaplan
04:09 PM phipli: but... Kaplan have compound curves on the blades
04:12 PM fragalot: nothing gloops can't make on his cnc
04:12 PM gloops: cant do the undercuts
04:13 PM gloops: could do it in layers
04:13 PM phipli: machine some dies and press them?
04:13 PM fragalot: you make the bladezs separately and dovetail them in
04:13 PM fragalot: seriously that keyboard glitch
04:13 PM fragalot: eds
04:14 PM gloops: fragalot i think thats a kind of freudian slip - hints at your past as a hax0r
04:14 PM fragalot: if I hit E D and S in rapid succession, it puts a z in
04:14 PM fragalot: or if I hold down e and d, then push s, it always types zs
04:15 PM gloops: you could make molds an laminate them, grp
04:15 PM gloops: fill with foam
04:16 PM phipli: Laser sinter them
04:18 PM phipli: If I spill my drink in my keyboard, does it say "connection reset by beer"?
04:19 PM gloops: it never did for me
04:20 PM phipli: for all those times?
04:22 PM gloops: i keep the keyboard mostly under the ledge these days, this one is doing well over a year old
04:30 PM JT-Shop: hey phipli
04:31 PM JT-Shop: this is what I ended up with and very delicious http://gnipsel.com/recipes/snacks/pickled-eggs.html
04:31 PM dioz: i have never spilled a drink on my keyboard
04:31 PM dioz: and i've been keyboard warrior for years and years
04:32 PM phipli: hey JT-Shop
04:33 PM Roguish: cokacola is the worst...........
04:33 PM phipli: enjoying the pickles?
04:33 PM JT-Shop: wife put some in pickle juice and yuck! these are good
04:35 PM phipli: https://www.youtube.com/watch?v=n_6p-1J551Y
04:37 PM JT-Shop: hmm sometimes they don't show the whole cube but neat
04:39 PM phipli: I've been playing with gtk and python
04:39 PM phipli: is that what you use for your guis JT-Shop?
04:39 PM JT-Shop: yea gtk and python are my go to programming tools
04:40 PM phipli: do you use Glade or something else?
04:42 PM JT-Shop: yea Glade for complex projects
04:42 PM JT-Shop: how's your flock?
04:43 PM phipli: dioz, https://www.aliexpress.com/item/High-quality-20kw-150rpm-low-rpm-horizontal-wind-turbine-generator-permanent-magnet-ac-generator/32663144305.html
04:43 PM phipli: JT-Shop, not too bad - one has started sleeping under the others and getting covered in poop
04:43 PM phipli: the others are well
04:44 PM phipli: yours?
04:44 PM phipli: how is the trouble maker?
04:44 PM JT-Shop: he's in the neighbors freezer and real quiet now
04:45 PM MarcelineVQ: hoho
04:45 PM JT-Shop: she brought 12 of her trouble makers to a lady that processes chickens so Henry went with them...
04:46 PM phipli: http://elephantandchicken.co.uk/chickenProjects/20180414_Chickens.jpg
04:47 PM phipli: Most helpful he's been in a while then
04:47 PM phipli: can you guess who got pecked about 3 seconds later?
04:47 PM JT-Shop: yea, no more problems
04:48 PM JT-Shop: the black and white one
04:48 PM JT-Shop: what is the white stuff?
04:48 PM JT-Shop: brb gotta finish a batch of pickled eggs
04:49 PM phipli: something like this : https://www.amazon.co.uk/Hentastic-Foraging-Cake-Feeder-available/dp/B00FGR6ED4/
04:53 PM JT-Shop: cool, time for some chicken treats
04:57 PM phipli: I should vanish anyhow
04:57 PM phipli: night folks
05:00 PM XXCoder: dang thats expensive motor
05:04 PM JT-Shop: night
05:05 PM JT-Shop: sign in as someone you don't like and click on buy it now lol
05:06 PM JT-Shop: well crap now we have a freeze warning for tonight
05:07 PM XXCoder: lol
05:07 PM XXCoder: dang freeze?
05:07 PM XXCoder: here its just forever rains
05:08 PM XXCoder: this is when calfornia people move back to calfornia
05:08 PM XXCoder: SAD
05:08 PM JT-Shop: refrigerator quit cooling... gotta drain the hose now
05:08 PM * JT-Shop wonders if this winter will ever end
05:09 PM XXCoder: don't worry in 10 years it will end
05:10 PM JT-Shop: I better go do it now or I'll forget
05:33 PM fred4106: Has anyone here build linuxcnc on linux-mint 18.3 with the "4.1.0-1-rtai-686-pae" kernel?
05:36 PM XXCoder: im not sure why linuxcnc must be on latest os
05:36 PM XXCoder: I would just make sure it works well
05:37 PM XXCoder: and update only when linuxcnc updates
05:37 PM pink_vampire|3: the lathe is up and running!
05:37 PM pink_vampire|3 is now known as pink_vampire
05:38 PM XXCoder: yay!
05:38 PM XXCoder: made anything yet?
05:38 PM pink_vampire: no,
05:39 PM pink_vampire: i just finished the wiring
05:39 PM pink_vampire: and did a test for the motor
05:39 PM XXCoder: cool :)
05:40 PM pink_vampire: i need to make a cover for the electrical box
05:40 PM fred4106: I had it running on the released iso. I just kept getting into situations where I wanted to get a program and my options where either, build it and all deps from source or not get it all. Current pet project is getting an xbox kinect to scan an object on a 4 axis mill and build a point cloud and .stl model.
05:41 PM XXCoder: I would build another pc for that
05:41 PM fred4106: I had both parts working, but integrating them onto one pc/linux install is a nightmare
05:41 PM XXCoder: I wouldnt want to use linuxcnc pc as pc for other stuff also
05:41 PM XXCoder: keep it as clean as possible for best perforance
05:42 PM pink_vampire: it's a manual lathe
05:42 PM XXCoder: pink it was to fred :)
05:42 PM pink_vampire: mmm ok
05:47 PM XXCoder: pink I'm curious what you plan to make on it lol
05:51 PM fred4106: So I should have a second pc do the machine vision part of the project and have it issue move commands over the network to linuxcnc pc or something?
05:52 PM fred4106: Not that it dosent make sense to do it that way. Just means setting up another pc in the garage. Wife is already upset with the Mill and one pc...
05:53 PM XXCoder: I wonder if something like orangepi could do scan stuff
05:55 PM fred4106: Realtime scanning is resource intensive, but just taking and storing the depth maps is pretty minimal resource wise
05:55 PM fred4106: Its the "converting to 3d model"
05:55 PM fred4106: that takes lots of processor time
05:55 PM XXCoder: hmm yeah
05:56 PM XXCoder: orangepi even ripoff cheap chinseium ones, is 4 core cpu
05:56 PM XXCoder: so its far more powerful than raspi
06:15 PM CaptHindsight: https://www.youtube.com/watch?v=xMP_AfiNlX4&feature=youtu.be
06:15 PM CaptHindsight: Building Prototypes Dan Gelbart part 1 of 18 Introduction
06:15 PM pink_vampire: very good videos!
06:16 PM CaptHindsight: Dan Gelbart views ~100K, reprap Miliions :)
06:18 PM SpeedEvil: yeah
06:18 PM SpeedEvil: Flexures are cool
06:19 PM pink_vampire: every video there are super useful
06:19 PM CaptHindsight: the whole series
06:19 PM gregcnc: pssh who would want to work to microns
06:20 PM CaptHindsight: A morons guide to microns
06:43 PM enleth: coincidentally, I'm working on a simple spectrometer design right now for a friend who's trying to build one
06:44 PM enleth: and I'm using some of Tom Lipton's tricks
06:45 PM enleth: to get micron precision in the finished assembly when not a single individual part is anywhere close to that
06:45 PM pink_vampire: what kind tricks?
06:46 PM Roguish: enleth: hey, which Tom Lipton ?
06:46 PM Roguish: link?
06:46 PM pink_vampire: oxtools
06:46 PM enleth: Roguish: oxtoolco
06:46 PM Roguish: use to work with him at Berkeley National Lab.
06:47 PM Roguish: very nice guy.
06:47 PM enleth: pink_vampire: the way he makes flextures, differential screws and kinematic mounts out of bog-standard hardware
06:47 PM enleth: Roguish: lucky you
06:49 PM enleth: I'd like to meet him someday, but I'm not particularily fond of traveling in general, and traveling to the US in particular
06:50 PM Roguish: he's here in the San Francisco area. East Bay, Martinez.
06:50 PM Roguish: no, oh, Benicia I think.
06:50 PM Roguish: just around the corner. so is Mesanet.
06:51 PM enleth: that's like right nex...
06:51 PM enleth: right.
06:51 PM enleth: I was about to say that
06:52 PM enleth: well, I guess *if* I visit the US anytime soon, it's going to be SV, so there's a non-zero chance I could drop by if he happens to be in the mood to have a visitor
06:53 PM Roguish: what's 'SV'
06:53 PM enleth: Silicon Valley
06:53 PM Roguish: yeah, that's here. other end of the Bay.
06:55 PM gregcnc: what's that about making differential screws?
06:56 PM enleth: Roguish: BTW, do you know if he's by any chance from Canada? I showed his videos to my boss, a Canadian from around Toronto, who kinda looks like Tom but 30 years younger, and even sounds quite alike, with similar speech patterns and mannerisms - and my boss said that Tom actually does sound somwhat Canadian in general, not just similar to him
06:57 PM Roguish: no. no clue.
06:59 PM enleth: gregcnc: you get two screws with a very small TPI difference and diameters selected so that you can drill one of them axially and tap it to accept the other one, then you screw the outer one into one part and anchor the inner one to the other part
06:59 PM enleth: gregcnc: the result you get is a micrometer precision screw made out of hardware store products
07:00 PM enleth: oh, and one needs to have a left handed thread, doesn't matter which
07:00 PM gregcnc: eh, that won't work for what i want to to. I wanted to avoid broaching a tiny hex
