12:00 AM * evilroot misses that reactor
12:02 AM evilroot: My own personal star . . . . the Fire Inspector really lost his shit about it being in my dorm room though
12:02 AM evilroot: So I sold it on the Anandtech forums. Wonder if that's still even a thing
12:02 AM pfred1: I remember Anandtech
12:02 AM roycroft: i didn't do the sanitary welds, but i designed that brewhouse and built the rest of it myself
12:02 AM pfred1: it was computer hardware benchmarking site
12:02 AM pfred1: that and tomshardware
12:02 AM roycroft: the next iteration of the control panel will have arduinos for the pid controllers, and a rpi as the main controller, and nixie tube displays
12:03 AM pfred1: https://forums.anandtech.com/
12:03 AM roycroft: at the other end of the spectrum, this happened last winter:
12:03 AM roycroft: www.zymurgasm.com/Aspen/Aspen1.jpeg
12:04 AM roycroft: www.zymurgasm.com/Aspen/Aspen2.jpeg
12:04 AM roycroft: there's a finnish farmhouse beer called sahti
12:04 AM roycroft: the mash is filtered through a hollowed-out aspen log that is lined with juniper branches
12:04 AM roycroft: the juniper is used for bittering in lieu of hops
12:04 AM pfred1: of course
12:04 AM roycroft: next spring i plan on making sahti
12:05 AM roycroft: it will be a very primative brew
12:07 AM * roycroft finally finished cutting that tree down a few weeks ago and saved two nice pieces for the kuurna (filtering log)
12:10 AM pfred1: I have to do some tree work here
12:10 AM pfred1: I should drop some big ones
12:10 AM roycroft: i brew some ancient brews, in a family called gruits
12:10 AM roycroft: which use herbs other than hops for bittering
12:10 AM pfred1: stick with the classic
12:10 AM roycroft: i'm working on a seminar that will be about brewing without instruments
12:10 AM roycroft: no thermometer
12:10 AM roycroft: no hydrometer
12:10 AM roycroft: no scale
12:10 AM CaptHindsight: roycroft: doesn't that summon evil nordic faeries?
12:10 AM roycroft: it might
12:10 AM pfred1: that's like how i make pancakes
12:10 AM roycroft: i like teaching people how brewing works
12:10 AM roycroft: not how to blindly follow recipes
12:10 AM roycroft: i teach how hydrometers work
12:11 AM pfred1: one can pop a beer cap with a lighter too
12:12 AM * evilroot yawns
12:12 AM CaptHindsight: roycroft: do you hold up all your trees using electrical and telephone wires?
12:12 AM pfred1: you can get in there without a church key!
12:12 AM evilroot: I used to have a Rotavap
12:12 AM evilroot: AKA the ultimate personal distilling machine
12:12 AM roycroft: those overhead wires made felling that tree interesting
12:12 AM evilroot: Then I got broke and sold it. Story of my life
12:13 AM evilroot: But it was crazy awesome for a while
12:13 AM roycroft: fortunately, when i started cutting the upper limbs off, the tree sprung back up a bit
12:13 AM roycroft: i still have to pull the stump
12:13 AM roycroft: i'm going to wait until the rainy season starts before i work on that
12:13 AM roycroft: the soil around the stump is like concrete right now
12:14 AM roycroft: i would have to jack hammer it to dig it up
12:14 AM pfred1: easy digging here it is all sand
12:15 AM roycroft: hard clay here
12:15 AM CaptHindsight: I had a similar one. I think they like electrical wires
12:15 AM pfred1: dig all day never see a rock
12:15 AM roycroft: and rocks
12:15 AM pfred1: nope no rocks at all here its weird
12:15 AM pfred1: biggest rock I ever saw was about a half an inch quartz pebble
12:15 AM CaptHindsight: 3ft soil followed by 100ft of clay then miles of limestone
12:15 AM pfred1: basically an overgrown grain of sand
12:16 AM pfred1: I put it on my windowsill
12:16 AM pfred1: I was about 5 feet down when i found it
12:17 AM pfred1: it's like playing at the beach
12:17 AM CaptHindsight: we had a glacier covering the area till about 10k years ago, left these big lakes
12:18 AM roycroft: http://zymurgasm.com/BrewSystem/QuadWort/4PostBoil.jpeg
12:18 AM roycroft: there's some of my westvlateren-12-like beer
12:19 AM roycroft: http://zymurgasm.com/BrewSystem/QuadWort/1MashIn.jpeg
12:19 AM roycroft: that's how the wort looked when i first mashed in
12:20 AM roycroft: i did a double decoction brew for that
12:20 AM roycroft: decoctions are when one pulls a small amount of the wort from the mash tun and boils it, then returns it to the mash to increase the temperature
12:20 AM roycroft: http://zymurgasm.com/BrewSystem/QuadWort/2FirstDecoction.jpeg
12:21 AM roycroft: that's after the first decoction
12:21 AM roycroft: decoctions develop color, amongst other things
12:21 AM roycroft: http://zymurgasm.com/BrewSystem/QuadWort/3SecondDecoction.jpeg
12:21 AM roycroft: that's after the second decoction
12:21 AM roycroft: noticeably darker
12:22 AM CaptHindsight: roycroft: have a wide shot of the whole setup?
12:22 AM roycroft: i don't remember the temperatures i used offhand, and can't be bothered to go find my logs, but i probably decocted to about 63c, then 67c for those decoctions
12:23 AM roycroft: the wort gets boiled down quite a bit (about 30% or more) in the kettle
12:23 AM roycroft: which concentrates the wort, darkening it
12:23 AM roycroft: also, the boiling action darkens it further
12:24 AM roycroft: http://www.zymurgasm.com/BrewSystem/BrewDay2/IMG_1014.JPG
12:24 AM roycroft: that shows the whole brew stand from the front
12:24 AM roycroft: http://www.zymurgasm.com/BrewSystem/BrewDay2/IMG_1022.JPG
12:24 AM roycroft: and from the rear
12:25 AM roycroft: i have a new kettle now
12:25 AM roycroft: and the control panel has been redone, but looks pretty simliar to the pictures i've posted
12:26 AM CaptHindsight: nice
12:27 AM roycroft: http://www.zymurgasm.com/BrewSystem/ControlPanelWiring/FirstPowerUp/
12:28 AM CaptHindsight: was thinking about putting a setup together but I have too many other projects
12:28 AM roycroft: there are some pictures of the new control panel
12:28 AM roycroft: i'm really happy with the molex connectors i added
12:29 AM roycroft: the old panel was a total spaghetti mess of wiring, because the panel chassis and the front panel were wired directly to each other
12:30 AM roycroft: none of the pictures of my brew system are organized at the moment
12:30 AM roycroft: i'm working on a new website that will document things better
12:30 AM roycroft: but too many projects, too little time ...
12:33 AM roycroft: http://www.zymurgasm.com/kuurna2.jpeg
12:33 AM roycroft: there's one of those finnish apsen log filters
02:22 AM IchGucksLive: morning from germany
02:23 AM XXCoder: hey from smokey tacoma
02:23 AM XXCoder: air condition is creeping up again :( its at 86
02:23 AM Deejay: moin
02:23 AM XXCoder: hey from smokey tacoma
02:24 AM IchGucksLive: yestrerday i have seen burning mountan lie in around tacoma
02:24 AM MarcelineVQ: fires flaring up again? it seemed a bit hazy here at the end of the day
02:24 AM IchGucksLive: i think cnbc
02:24 AM pfred1: fire!
02:24 AM XXCoder: MarcelineVQ: that is assuming it stopped
02:25 AM XXCoder: it didnt
02:25 AM XXCoder: just that cold front cleared it away but its building smoke up again here
02:25 AM XXCoder: tomorrow rain will clear it again, and hopeflly kill few fires
02:25 AM pfred1: fire good
02:26 AM XXCoder: pfred1: its part of nature, just that its real annoying and my body seem to react badlu with smoke, im been poorly for weeks now
02:26 AM pfred1: I don't like smoke either
02:27 AM pfred1: how about that guy that jumped into the Man?
02:27 AM pfred1: now there was a real fan of fire
02:27 AM XXCoder: youre talking about burning man event?
02:27 AM pfred1: heh yeah
02:27 AM XXCoder: I do want to go there see some stuff, though not overnight
02:28 AM pfred1: BM is far from cool anymore
02:28 AM XXCoder: I'd love to bring interpeter with me
02:29 AM XXCoder: why pf
02:29 AM pfred1: they used to hold it on a beach
02:29 AM pfred1: too many posers there now
02:30 AM XXCoder: and more darktards I guess lol
02:30 AM pfred1: dilletants whatever you want to call them hipsters?
02:30 AM pfred1: assholes basically
02:30 AM XXCoder: swo, what happens if hipsters becomes popular?
02:30 AM XXCoder: meaning over 50% are hipsters
02:32 AM MarcelineVQ: they'll have to change the meaning of the word again
02:33 AM pfred1: the sad thing is by the time I hear about anything it is far past done
02:34 AM XXCoder: ya know, what if I play randomly on some music thing, and since im very unknown, would I get lots money from hipsters that pretend they love me because im not well known?
02:51 AM IchGucksLive: later ;-)
03:02 AM gloops: why dont they write simple instructions for chinese kit
03:02 AM gloops: most things these days are made so that idiots can fit them
03:03 AM gloops: but you need a degree in electronics if you have to work it out yourself
03:04 AM archivist: they dont like learning english to write the manuals
03:05 AM gloops: well they could get some western business to draw one up
03:06 AM archivist: that would eat into profits too
03:06 AM gloops: it only needs one to do it, the rest could copy it, they copy the kit anyway
03:07 AM archivist: I dont think they like the cost of a sheet of paper either
03:07 AM gloops: right, i connect the vfd, then im using stepconfig to deal with the pins ?
03:08 AM gloops: or where do i allocate the pins from the breakout board
03:08 AM archivist: stepconf is a beginners tool yes then you may want to edit the hal files direct
03:09 AM gloops: archivist i have had 4 lengthy sensuous emails from an alleged chinese lady asking if my spindle is ok and am i leaving feedback - id rather have had a wiring diagram in english
03:10 AM gloops: hal is where pins are set? i havent looked in hal much at all yet, i will learn this when i get the damn thing running
03:11 AM archivist: is there some pdf available or example where someone else used one
03:11 AM CaptHindsight: gloops: it's more like a pride thing
03:11 AM gloops: been looking, not found a clear one yet, quite a few for mesa and gecko stuff, not so much for old pc and bob
03:12 AM CaptHindsight: my partners there would never ask me to proof anything even when I'd ask them to please do so
03:12 AM archivist: for some setups, stepconf cannot deal with all connections, it does not have every possible use programmed in(impossible)
03:12 AM gloops: i guess im just gonna have to go and do it, the hardest part is getting up to start
03:13 AM CaptHindsight: gloops: it's easier when someone else takes you chair :)
03:13 AM CaptHindsight: you/your
03:13 AM gloops: well, i think i can work it out, what annoys me is that it takes a lot longer if you dont know what you are even looking at
03:15 AM archivist: knowing some electronics terms helps :) ask when stuck
03:15 AM gloops: i got a video for the wiring, but using mach 3, wiring is same, ill do that then look at config
03:16 AM archivist: video is just wrong for this sort of thing
03:16 AM gloops: vdd is 0-10v signal yes?
03:16 AM archivist: pwm drives 0-10
03:16 AM gloops: its all there is, id rather have a diagram and sit and study it and compare to the hardware ive got
03:17 AM gloops: on the breakout board i got a vdd pin, the video is using that for 0-10v signal, and grounded
03:17 AM gloops: another 5v pin for on/off
03:17 AM gloops: thats all i want, speed - on/off
03:18 AM archivist: this bob http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG ?
03:18 AM XXCoder: thats essentaly what I have alsop
03:18 AM XXCoder: works well.
03:18 AM gloops: yes thats the only pic ive found, im going with that wiring
03:19 AM archivist: note the connections on that image
03:19 AM gloops: fwd on vfd is on..i think
03:20 AM gloops: grounding to common rail
03:20 AM archivist: noo
03:20 AM archivist: see also http://www.collection.archivist.info/archive/mirror/cnc/bob/$_58.JPG
03:20 AM archivist: grounds are isolated by the bob be careful
03:21 AM gloops: http://www.commenthow.com/article/display/8944?offset=6&max=1
03:21 AM archivist: that is one of its main jobs, isolate grounds to reduce electrical noise
03:22 AM gloops: i mean ground on vfd end goes to common?
03:24 AM archivist: there are a few grounds, input ground, the 5v ground, and check with a meter, the 0-10 gnd is common with the 12v input
03:24 AM archivist: it should be safe to connect the 5 and 12v grounds
03:25 AM archivist: there are some other versions in http://www.collection.archivist.info/archive/mirror/cnc/bob/
03:26 AM archivist: but I dont connect 5v and 12v grounds I have them isolated
03:27 AM archivist: because where is your 5v from? usually the pc therefore it is not isolated
03:28 AM archivist: the drivers also have isolation built in so the bob does not need to isolate drive signals to the stepper drivers
03:31 AM archivist: so I used the relay output to enable the vfd, it is stuck in forward only
03:33 AM gloops: yes relay for on off
03:33 AM gloops: my pwn pin on the bob is marked vdd
03:33 AM gloops: does that sound right?
03:41 AM archivist: no
03:42 AM archivist: the pwm internally drives the 0-10 v output, ignore it
03:43 AM archivist: just connect the signal to the correct pin on the parallel port, connect 12v then check the 0-10 output
03:46 AM gloops: finishing this tea then im on it
03:47 AM MrSunshine_: i can backlash compensate each joint right ?
03:47 AM MrSunshine_: even if the joints drive the same axis
03:48 AM archivist: never tried to do that
03:48 AM archivist: but probably
03:48 AM gloops: would think so
03:48 AM gloops: BACKLASH =
03:49 AM archivist: scanned a manual, had breakfast now steam engine time ish
03:50 AM gloops: do you ever have any dealings with a man from kiveton park near rotherham, archivist?
03:50 AM archivist: no
03:50 AM gloops: forget his name now, i got an old lathe off him, hes got a fair sized unit full of old steam stuff and machines
03:51 AM gloops: he had a tractor and another engine outside
03:51 AM archivist: just had to scan a Gent clock manual for Midland Railway centre :)
03:53 AM gloops: it is fascinating stuff, expensive hobby though
03:53 AM gloops: anyway bbl
03:54 AM MrSunshine_: does backlash compensation work best with climb milling or conventional ?
03:59 AM archivist: conventional, best not to need it
04:00 AM archivist: climb can pull the material in by backlash amount causing a tool break
04:17 AM MrSunshine_: archivist, yeah gonna look at if i can add another nut to the equation but im not sure it will be enough space for one :/
04:28 AM gloops: how about single split nut
04:29 AM MrSunshine_: its ballscrews ...
04:31 AM evilren: split nut works awesome on my taig
04:32 AM evilren: theres forum post somewhere about heat forming split nuts from delrin using the screw
04:32 AM evilren: i think it was for ballscrews, dont remember tho
04:33 AM gloops: they do sell antibacklash secondary nuts for ballscrews, i cant see it working for a mill though
04:34 AM gloops: people with lazers and light routers maybe, you some load on with a mill though
04:38 AM gloops: right, am connected to vfd for on/off circuit on the relay pins on bob, how do i confid that switch?
04:38 AM gloops: no option in stepconfig for those pins
05:32 AM jthornton: morning\
05:33 AM XXCoder: yo
05:41 AM jthornton: hmm the arduion editor find and replace is a bit dumb
05:44 AM XXCoder: yeah?
05:44 AM jthornton: yea it doesn't limit the search to whole words lol
06:55 AM jthornton: now if I can just figure out how to set the time in the DS3231 from the pc time and date...
07:49 AM SpeedEvil: https://www.youtube.com/watch?v=FxVPM08jnGM - neat. 123 block lego
07:50 AM XXCoder: fancy
07:51 AM SpeedEvil: Pretty simple idea.
07:51 AM SpeedEvil: as the best are
07:53 AM XXCoder: dont 123 usually need baking then grind to good precision
07:57 AM SpeedEvil: yes, that's the next step
07:58 AM SpeedEvil: he has a surface grinder, and sends stuff out to be hardened
07:58 AM SpeedEvil: (in his other videos)
08:00 AM XXCoder: ahh ok
08:00 AM XXCoder: too bad I never had chance to make couple 123s.
08:01 AM XXCoder: that was my next manual milling training
08:01 AM XXCoder: but I got hired so yeah
08:11 AM SpeedEvil: :)
08:12 AM XXCoder: to make up I bought 2 of em because why not.
08:12 AM XXCoder: come in handy few times lol
08:15 AM XXCoder: well later heh
09:15 AM gloops: https://www.robotics.org.za/image/data/Stepper_Motor_Automation/CNC_Breakout/OT382_functions.jpg
09:15 AM gloops: this breakout board
09:16 AM gloops: by default linuxcnc is allocating pin 14 for spindle on and off, (spindle) test shows 6v for on and .3 volts for off, no change at the spindle
09:17 AM gloops: pretty lost as to which pin to use for 0-10v or 0-5v for speed control
09:17 AM gloops: lncnc allocating pin 15
09:20 AM gloops: i dont think this board can do it
10:40 AM miss0r: Fuck! I just drilled through a part with a 25mm drill to make some clearance for easier boring the bearings in the end... only I forgot that the axle seals that was to go on the inside of the bearings only measured 22mm on the outside ! :'(
10:41 AM Jymmm: miss0r: get bigger seals?
10:42 AM miss0r: not that fits the axle, no. I'm looking at ordering some
10:42 AM Jymmm: miss0r: or a walrus instead
10:43 AM miss0r: is that a slang I do not know, or are you being funny and talking about a huge animal? :]
10:43 AM Jymmm: seals, walrus, and other aquatic mammals, oh my!
10:44 AM miss0r: being funny i see.... :]
10:44 AM miss0r: And I don't want to remake the axle... I hate machining stainless
10:45 AM miss0r: well.. when the diameter is that small atleast
10:46 AM miss0r: Bleh. I've just decided to order a pizza and call it a day. see you around
10:56 AM IchGucksLive: hi all
11:01 AM gloops: hi Ichs
11:01 AM gloops: just the man!
11:07 AM gloops: https://www.robotics.org.za/image/data/Stepper_Motor_Automation/CNC_Breakout/OT382_functions.jpg
11:07 AM gloops: have a quick look at that is you get a minute
11:08 AM IchGucksLive: gloops: its the old Board
11:08 AM IchGucksLive: no extras
11:09 AM IchGucksLive: as i said to you better to invest 5USD
11:09 AM gloops: so cant connect vfd
11:09 AM gloops: which type of board?
11:09 AM gloops: i mean what am i looking for specifically
11:09 AM IchGucksLive: i told you to get the newer one
11:10 AM IchGucksLive: https://www.youtube.com/watch?v=I00ArvYvZgI
11:10 AM IchGucksLive: this has all onboard that you need just connect
11:10 AM gloops: i only get one sessions logs, ill have a look on ebay anyway, looking for 0-10v pin and a relay
11:10 AM IchGucksLive: the board has all on it
11:11 AM IchGucksLive: dont spend 10USD on a Analog/pwm
11:11 AM IchGucksLive: then getting a board at 6USD
11:11 AM gloops: ok ill look for it by sight lol, these things dont have names or numbers
11:11 AM IchGucksLive: its the mach interfaceboard
11:12 AM IchGucksLive: you are in the uk or
11:12 AM gloops: yeah in uk, local stock wont be $5 - more like £30 or £40
11:13 AM IchGucksLive: i see 10
11:14 AM gloops: cant see any like that
11:14 AM IchGucksLive: i cand give you the item number as it tryes to get me to german dealers first
11:14 AM IchGucksLive: 282043216600
11:14 AM IchGucksLive: 331632334051
11:15 AM IchGucksLive: 262501735617
11:16 AM IchGucksLive: be informed only the green one is the good
11:16 AM IchGucksLive: the blue will not make it
11:18 AM gloops: right, 282043216600 is ok for it? thats in the post in a couple of clicks, in fact ill look for the quickest post, probably the same though
11:19 AM gloops: had a couple of hours messing with it this morning, realised what you were saying before
11:23 AM gloops: http://www.ebay.co.uk/itm/Cnc-5-Axis-Interface-Breakout-Board-For-Stepper-Motor-Driver-Cnc-Mill-Mach3-BS-/201730661523?hash=item2ef8159c93:g:kSAAAOSwImRYHZJA < one here in UK quicker post and surprisingly cheaper
11:25 AM IchGucksLive: gloops: get it you will be impressed
11:25 AM gloops: right its on its way, i can still get this finished this week
11:25 AM IchGucksLive: get the connectors also if you are using standard bricks its easy to mount
11:25 AM gloops: which connectors?
11:25 AM IchGucksLive: the white ones
11:26 AM IchGucksLive: or are you using cables
11:26 AM gloops: ahh right yes can see the plugs - im only using cables atm
11:26 AM IchGucksLive: the Pin 14 is the trick
11:26 AM gloops: would be better with the connectors
11:26 AM IchGucksLive: the connectors are JST-xh-3s
11:26 AM gloops: yes i noticed linuxcnc was setting p14 as spindle on/off
11:26 AM IchGucksLive: look in uk ebay on it
11:26 AM gloops: by default
11:27 AM IchGucksLive: dont leve the bricks powerd connect EN via pin14
11:27 AM IchGucksLive: and use Mashine enabled in the stepconf
11:27 AM IchGucksLive: the relai will give you the Spinle FWD
11:28 AM IchGucksLive: and the 0-10 the speed
11:28 AM IchGucksLive: go liniar on the stepconf
11:28 AM IchGucksLive: so 0=0 and 1=24000
11:28 AM IchGucksLive: then you are good at RPM over 7000
11:29 AM gloops: right some of that is making sense now lol, now ive actually looked at it
11:30 AM gloops: will have to work out the pin 14 part
11:30 AM gloops: this is standard hi/low pin yes?
11:34 AM gloops: right, in the post, i can now close about 10 windows with wiring diagrams for the old board
11:36 AM IchGucksLive: thats why it is so popular
11:36 AM IchGucksLive: but its a mess
11:37 AM IchGucksLive: it is quite easy
11:37 AM IchGucksLive: im off
11:42 AM MacGalempsy: good moring
11:42 AM MacGalempsy: *morning (at least here)
11:55 AM JT-Shop: yep still morning here too lol
11:56 AM Loetmichel: MacGalempsy: good morming from germany...(wife let me sleep 'til 18:00) ;)
11:57 AM gloops: early evening here in UK, kinda grey with a few blue bits of sky, violent short showers earlier
11:59 AM Loetmichel: gloops: same here... just looked outside: my convertible windows are foggy from the inside. meaning whe had some really violent showers today...
11:59 AM Loetmichel: <- puts on some trousers ang goes outside, opening the canopy, so it can dry out ;)
12:00 PM gloops: i left something out on the drive and the rain was so hard i couldnt go out for it, would have been soaked in seconds
12:09 PM MacGalempsy: Loetmichel! What a great wife!
12:09 PM MacGalempsy: Did she bring you dinner in bed?
12:12 PM Loetmichel: MacGalempsy: you mean after exiling me to the guest room this night for snoring?
12:12 PM Loetmichel: no, she didnt
12:14 PM MacGalempsy: :( that is no good.
12:15 PM MacGalempsy: updating will have to reboot in a moment
12:26 PM MacGalempsy: huh, no update
12:26 PM MacGalempsy: I mean no reboot required
12:32 PM IchGucksLive: hi im back ;-)
12:34 PM IchGucksLive: gloops: still online
12:34 PM gloops: still around for a bit, hi
12:35 PM IchGucksLive: shoudt i make you a short wire diagramm for the vfd to the bob
12:35 PM gloops: would be very useful if you have time, it wont be here till wednesday though,
12:36 PM gloops: not doing much work this week so i have time to study it and get it working - spindle is last thing to do
12:37 PM IchGucksLive: is this your vfd https://planet-cnc.com/controlling-spindle-output-board/
12:38 PM IchGucksLive: schemativ of cause
12:38 PM IchGucksLive: but better to show a image of the rewal document that came with it
12:38 PM gloops: looks pretty much the same, im just looking for any serial number in the papers, nothing at all
12:39 PM IchGucksLive: so FOR and DCM goes to the RELAI
12:39 PM IchGucksLive: no matter what in and out
12:39 PM IchGucksLive: and the VI goes to 0-10V
12:40 PM IchGucksLive: ACM is the 0-10V gnd pin next to the 0-10V pin on the board
12:40 PM gloops: http://www.ebay.co.uk/itm/1-5KW-AIR-COOLED-SPINDLE-MOTOR-1-5KW-VFD-HIGH-SPEED-INVERTER-MILL-GRIND/172380219589?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D46150%26meid%3D2164db5d6cf34e9d90654bcc90b29261%26pid%3D100005%26rk%3D5%26rkt%3D6%26mehot%3Dag%26sd%3D201484921885&_trksid=p2047675.c100005.m1851
12:40 PM IchGucksLive: gloops: SHORT TIP only the words up to the ? are used on ebay
12:41 PM gloops: right, ill screenshot that and save it
12:41 PM gloops: ok
12:41 PM IchGucksLive: thats it
12:41 PM IchGucksLive: so please mark my lines and copy past and yoiu are up
12:41 PM IchGucksLive: but i will do it for you
12:41 PM IchGucksLive: 5min
12:42 PM gloops: saved on desktop - Ichs spindle wiring
12:42 PM gloops: can understand why i was having trouble wiring it up - when the board didnt have the pins lol
12:51 PM IchGucksLive: gloops: done
12:51 PM IchGucksLive: uploading
12:52 PM IchGucksLive: http://heimwerkermarkt-tretter.de/VFD_bob_wire.jpg
12:53 PM gloops: right got it
12:53 PM gloops: dcm is a ground, and acm
12:53 PM gloops: VI 0-10v
12:53 PM gloops: FOR = 5v on/off relay
12:53 PM IchGucksLive: DONT mess up
12:53 PM IchGucksLive: it is 4wirers
12:53 PM gloops: lol
12:54 PM gloops: just check if ive got VI
12:54 PM IchGucksLive: FOR is GND
12:54 PM IchGucksLive: dont connect it to a BOB pin
12:54 PM IchGucksLive: you will see a nice firerwork
12:55 PM IchGucksLive: as the left SMD will take a nice hole burn
12:55 PM IchGucksLive: Connect as it is shown
12:55 PM gloops: ahh
12:55 PM IchGucksLive: the 12V isent to be connected to the VFD
12:55 PM IchGucksLive: keep this appart
12:56 PM gloops: not got port marked VI - have got 10v IN
12:56 PM gloops: i can study this anyway and look at it
12:56 PM IchGucksLive: pleas make a photo/picture of the VFD pionout in the documentation
12:59 PM IchGucksLive: ok i think you will do it right
01:01 PM IchGucksLive: im off for today ;-) got work todo corn harvest is right at the beginning
01:01 PM gloops: ok i will upload pic for tommorrow
01:02 PM gloops: thanks for the help Ichs
01:02 PM malcom2073: evilroot: You Dave?
01:02 PM evilroot: No . . .
01:02 PM evilroot: o.O
01:03 PM archivist: which dave, they are common
01:03 PM malcom2073: someone posted a picture of your Seiko on a facebook CNC group
01:04 PM evilroot: I have sold a few
01:04 PM evilroot: Just sold one to a guy from the Sparkfun channel, that might be him
01:04 PM evilroot: What's the group?
01:05 PM malcom2073: https://www.facebook.com/groups/cncdiy
01:06 PM malcom2073: evilroot: how much you selling them for?
01:07 PM evilroot: $1200 for the larger ones
01:07 PM evilroot: $900 for a bit smaller
01:07 PM malcom2073: Ah alright nm :)
01:07 PM evilroot: Honestly the motors and linear rails are worth more, but I'd hate to do that
01:08 PM malcom2073: My dad buys those all-in-one actuators, but he grabs them when they show up below $150
01:08 PM MacGalempsy: Hi Malcom
01:08 PM malcom2073: Hiya
01:08 PM evilroot: You mean the fully enclosed servos with drives built in?
01:08 PM malcom2073: No, the linear rail/screw/servo combos
01:08 PM evilroot: Ahh
01:09 PM evilroot: On the Y axis these have a 500W servo and like a 20mm ballscrew, with 25mm THK linear rails and pillow block bearings
01:09 PM evilroot: I don't really see that showing up at under $150 heh
01:10 PM malcom2073: They do heh
01:10 PM evilroot: Damn, really?
01:10 PM malcom2073: Yeah, you gotta watch the auctions pretty close, he usually gets 1 or so am onth
01:10 PM malcom2073: month*
01:11 PM malcom2073: Larger ones are less common, 15-20mm square rail are a bit more common, and built in recirculating troth style rails are even moreso
01:13 PM malcom2073: I think these had only 15mm rails: https://scontent-atl3-1.xx.fbcdn.net/v/t1.0-9/19511377_1467342916663342_3921492005640386333_n.jpg?oh=ad888beab27b60d153f2e7299749359e&oe=5A606CA0
01:22 PM gloops: oh sorry, was me that posted that pic - didnt think it was your private pic just something on the web
01:24 PM malcom2073: Well he posted it here, so it probably wasn't that private :P
01:25 PM malcom2073: gloops: What did you mean by diyable? Like, could you make your own out of the raw rails, screw, and motor?
01:26 PM gloops: was mainly thinking of the one sided X axis design- would be a challenge to make one like that
01:26 PM gloops: rigid enough for work
01:26 PM malcom2073: I mean, that's not that much different than the normal head of say, a knee mill
01:26 PM archivist: making with raw rails/screws etc is possible
01:26 PM malcom2073: overhanging like that
01:27 PM gloops: i suppose yeah, for wood router people its more normal to think of 2 seperate rails
01:27 PM archivist: just remember the straightness of rails is the mounting of them
01:28 PM gloops: you have got some leverage going accross there
01:29 PM malcom2073: So does a knee mill, it's all about rigidity
01:31 PM archivist: add webs etc
01:31 PM gloops: well yeah, but a lot of those are castings and so on, hmm there are radial arm saws like that though
01:38 PM gloops: someone will probably make one out of MDF just to show how it done lol
02:16 PM CaptHindsight: who was making the polymer granite spindle holder (or similar) in stages?
02:16 PM CaptHindsight: was wondering how it turned out
02:30 PM * sadisticroot yawns
02:33 PM gloops: not seen it mentioned for a while, he was talking about setting the bearings in it, sounds a bit tricky
02:36 PM CaptHindsight: a week or so, he's up in one of those frozen northern EU countries
02:54 PM MrSunshine_: phew double nuts in place .. got the backlash down some .. but aparently is backlash in the otehr screw also :/ and need to get the gantry squared ... can compensate it but its a mechanical error to be fixed ...
02:58 PM CaptHindsight: after going through this you might appreciate why $3k positioners and $20 mills are made they way they are
02:58 PM CaptHindsight: $20k/$20
03:02 PM Cromaglious_: OK, finally got the T nut for the BXA cut down for my lathe, took 0.040" off the bottom of an 5/8 insert holder.
03:02 PM Cromaglious_: now I can get down to center height
03:03 PM Cromaglious_: I was about 0.030" above center height at lowest point
03:04 PM Cromaglious_: well my $13 fleabay 3/8" 3 flute carbide endmill is holding up well.
03:10 PM JT-Shop: rain quit, sun came out and now it's really warm and muggy
03:12 PM Tom_itx: cool here
03:13 PM JT-Shop: looks like mid 80's here all week
03:17 PM CaptHindsight: we had fall here a week ago and now it's back to July humidity
03:58 PM Cromaglious_: hmmm
03:58 PM * sadisticroot is still comparison shopping breakout boards
03:58 PM Cromaglious_: 22.5c right now... slightest of breezes
03:59 PM Cromaglious_: just emailed SIEG about pricing on some stuff.. I hear if you order more than 3 machines they do shipping..
04:00 PM sadisticroot: I'm really not seeing any advantage to the higher end boards over the simple parallel stuff
04:00 PM sadisticroot: Given the G320X handles most of the heavy lifting
04:02 PM sadisticroot: Or am I missing something?
04:03 PM Cromaglious_: well I'm running JMC.MOTOR.com NEMA23 iHSS56-36-20 (2nm 285ozin) integrated closed loop steppers. I need step generation and read sensors
04:03 PM Cromaglious_: jmc-motor.com
04:04 PM sadisticroot: All I really need are step/dir, reading if there is an error signal, and of course endstops
04:04 PM Cromaglious_: http://jmc-motor.com/products.php?cid=248&id=118 ooops iHSS57-36-20
04:05 PM sadisticroot: Plus a relay for the spindle. I figure I'll control the spindle speed manually
04:05 PM sadisticroot: https://www.ebay.com/p/W6-Upgraded-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-Mach3-USB-Cable/1873801680?iid=262485750955
04:05 PM sadisticroot: Honestly it seems like this would be fine
04:05 PM sadisticroot: Right?
04:06 PM Cromaglious_: I'm using a ebay bob http://www.ebay.com/itm/5-Axis-Breakout-Board-with-Optical-Coupler-CNC-for-MACH3-Stepper-Motor-Driver-/162144263602?epid=514119363
04:06 PM sadisticroot: Looks like the same board
04:07 PM Cromaglious_: same thing... lose the USb connector and get a 24v to 5v buck converter and wire in the 5v
04:08 PM Cromaglious_: then you don't have to futz with the usb cable
04:09 PM Cromaglious_: I was reading 12000 rpm with 36000 pulses minute (3 magnets) through that board
04:11 PM Cromaglious_: my problem is step generation. crappy computer can't get high enough step rates to satify me
04:16 PM sadisticroot: I already have 5v on the bot
04:16 PM sadisticroot: The motors run at 70V
04:16 PM Cromaglious_: Dial Gauge Test Indicator Precision Metric with.Item ID: 302368645261 Quantity: 2 Estimated delivery: Mon. Oct. 16 - Sat. Nov. 4 Paid: $20.62 with PayPal
04:17 PM sadisticroot: Cromaglious_: is that the computer or the parallel port's limitations?
04:17 PM Cromaglious_: computer atom 1.4ghz mini itx board
04:18 PM sadisticroot: Oh yeah, I remember
04:18 PM Cromaglious_: far as I know a parallel port with a 3' cable can do around 1mhz
04:18 PM Deejay: gn8
04:18 PM Cromaglious_: nite dj
04:18 PM sadisticroot: I'll be running an i7 with 8gb ram so ought to be fine
04:19 PM Cromaglious_: no parallel port on this machine :(
04:19 PM sadisticroot: Any recommendations on a spindle motor? I want to be able to do aluminum
04:19 PM Cromaglious_: oops this is a Core2 T6600, new laptop is a i7-7500U dell
04:20 PM Cromaglious_: I just got a ER16 65mm air cooled 1.5kw spindle with VFD (needs 240vac though) $283
04:20 PM Cromaglious_: looking for the listing
04:22 PM sadisticroot: I have 240, no issue there
04:22 PM sadisticroot: 1.5kw seems overkil for soft metal?
04:24 PM sadisticroot: I'm seeing 1.5kW er16 spindles on ebay for $140ish
04:25 PM sadisticroot: I'd prefer air cooled for simplicity
04:25 PM gloops: you want 1.5kw at least
04:25 PM gloops: only same price as 800kw anyway
04:26 PM Cromaglious_: this one iswhat I bought. http://www.ebay.com/itm/1-5KW-ER16-Air-cooled-Spindle-Motor-80mm-Four-Bearing-1-5KW-Inverter-VFD/232395496310

04:29 PM Cromaglious_: I also just bout a HF 44991 mini mill and added the Tormach Tooling System to it. TTS
04:31 PM Cromaglious_: now I can do STEEL! YAY
04:32 PM Cromaglious_: been machining all my lathe tool post tnuts finally..
04:45 PM CaptHindsight: http://www.ebay.com/itm/Colombo-Router-Spindle-12-2HP-continuous-duty-ISO-40-/132144563006 $1600
05:07 PM SpeedEvil: I don't need one that powerful, do you think he'd split it into a 3hp one for 400?
05:08 PM CaptHindsight: I think you just turn down the amps to get that :)
05:08 PM CaptHindsight: turn down/small amps
05:12 PM CaptHindsight: new old stock http://www.ebay.com/itm/Hardinge-Spindle-AA0704105-12000-RPM-BT40-NEW-/252970867893
05:12 PM CaptHindsight: tempting
05:33 PM gloops: i want all these machines and kit, problem is no time, takes ages to build one
05:34 PM sadisticroot: Hrm, I just realized I have an AC spindle driver . . . .
05:41 PM sadisticroot: Its 3-phase though
05:44 PM sadisticroot: Holy CRAP
05:44 PM sadisticroot: Its 27A 5.5kW!
05:45 PM sadisticroot: I had no idea the old spindle on that thing was so huge
06:32 PM Cromaglious_: ok 44991 is on the old dead air conditioner I screwed a 2x12 to the top
